This section contains the following subsections: 1.1 Background 1.2 Purpose and Authority 1.3 Scope 1.4 References 1.5 Plan Organization 11111111111��L11111111111 This document comprises a Local Mitigation Strategy for Monroe County, Florida. Each year in the United States,natural and human-caused hazards take the lives of hundreds of people and injure thousands more.Nationwide,taxpayers pay billions of dollars annually to help communities, organizations,businesses, and individuals recover from disasters. These monies only partially reflect the true cost of disasters because additional expenses incurred by insurance companies and non-govemmental organizations are not reimbursed by tax dollars. Many natural hazards are predictable, and much of the damage caused by hazard events can be reduced or even eliminated. Hazards are a natural part of the environment that will inevitably continue to occur,but there is much we can do to minimize their impacts on our communities and prevent them from resulting in disasters. Every community faces different hazards,has different resources to draw upon in combating problems, and has different interests that influence the solutions to those problems. Because there are many ways to deal with hazards and many agencies that can help,there is no one solution for managing or mitigating their effects. Planning is one of the best ways to develop a customized program that will mitigate the impacts of hazards while accounting for the unique character of a community. A well-prepared hazard mitigation plan will ensure that all possible activities are reviewed and implemented so that the problem is addressed by the most appropriate and efficient solutions. It can also coordinate activities with each other and with other goals and activities,preventing conflicts and reducing the costs of implementing each individual activity. This plan provides a framework for all interested parties to work together toward mitigation. It establishes the vision and guiding principles for reducing hazard risk and proposes specific mitigation actions to reduce identified vulnerabilities. In an effort to reduce the nation's mounting natural disaster losses, the U.S. Congress passed the Disaster Mitigation Act of 2000 (DMA 2000)to invoke new and revitalized approaches to mitigation planning. Section 322 of DMA 2000 emphasizes the need for state and local government entities to closely coordinate on mitigation planning activities and makes the development of a hazard mitigation plan a specific eligibility requirement for any local government applying for federal mitigation grant funds. These funds include the Hazard Mitigation Grant Program(HMGP), the Building Resilient Infrastructure and Communities (BRIC)program(formerly the Pre-Disaster Mitigation(PDM)program), and the Flood Mitigation Assistance(FMA)Program, all of which are administered by the Federal Emergency Management Agency(FEMA)under the Department of Homeland Security. Communities with an adopted and federally approved hazard mitigation plan thereby become pre-positioned and more apt to receive available mitigation funds before and after the next disaster strikes. �A('Irvrc)e courity, Mt�flht]",3L fllscfi�cda,4� oca��� Mitigat'ar'i Strategy Jw"W&�'y 2(`)26 SECTION 1: INTRODUCTION This plan was prepared in coordination with FEMA Region 4 and the Florida Division of Emergency Management(FDEM)to ensure that it meets all applicable federal and state planning requirements. A Local Mitigation Plan Review Tool, found in Appendix A,provides a summary of FEMA and FDEM's current minimum standards of acceptability and notes the location within this plan where each planning requirement is met. 11111111111��L2 U A AUIIIIIIIIIIIIIII�������illillillillilI 0 The Board of County Commissioners directed the Monroe County Emergency Management Department to coordinate and facilitate the development of the LMS, and subsequent 5-year updates, in conformance with state and federal guidelines. This plan was developed in a joint and cooperative manner by members of a Local Mitigation Strategy Working Group (LMSWG)which included representatives of County and City departments, federal and state agencies, citizens, and other stakeholders. This plan will ensure all jurisdictions in Monroe County remain eligible for federal disaster assistance including the FEMA HMGP, BRIC, and FMA programs. This plan has been prepared in compliance with Section 322 of the Robert T. Stafford Disaster Relief and Emergency Assistance Act(Stafford Act or the Act), 42 U.S.C. 5165, enacted under Section 104 of the Disaster Mitigation Act of 2000, (DMA 2000)Public Law 106-390 of October 30, 2000, as implemented at CFR 201.6 and 201.7 dated October 2007. Additionally,this plan meets the requirements set forth by the Florida Administrative Code Chapter 27P-22. This plan will be adopted by each participating jurisdiction in accordance with standard local procedures. Copies of adoption resolutions are provided in Section 9 Plan Adoption. This document comprises a Multi-Jurisdictional Local Mitigation Strategy for Monroe County. The planning area includes all incorporated municipalities and unincorporated areas in the region. All participating jurisdictions, along with additional local entities, are listed in Table 1.1. lt�he������4euse Participating,3urisdictions Participating Local Entities Monroe County Florida Keys Aqueduct Authority(FKAA) City of Key Colony Beach Florida Keys Electric Cooperative(FKEC) City of Key West KEYS Energy Services City of Layton College of the Florida Keys City of Marathon Islamorada Village of Islands The focus of this plan is on those hazards deemed"high"or"moderate"priority hazards for the planning area, as determined through the risk and vulnerability assessments. Lower priority hazards will continue to be evaluated but will not necessarily be prioritized for mitigation in the action plan. Monroe County followed the planning process prescribed by FEMA, and this plan was developed under the guidance of a Local Mitigation Strategy Working Group (LMSWG) comprised of representatives of County, City, and Town departments; citizens; and other stakeholders. The LMSWG conducted a risk assessment that identified and profiled hazards that pose a risk to the planning area, assessed the planning areal s vulnerability to these hazards, and examined each participating jurisdiction's capabilities in place to mitigate them. The hazards profiled in this plan are listed below: �A('Irvrc)e courity, Mt�I���tl 3L fllscfi�cda,4� oca��� MitigaU'ar'i Stjrategy Jw"W&�'y 2(`)26 ����)age 2 SECTION 1: INTRODUCTION — Flood — Tropical Cyclones — Severe Storms (Thunderstorm Wind, Lightning, Hail) — Tornadoes and Waterspouts — Wildfire — Coastal Erosion — Drought — Extreme Heat — Sea Level Rise and Other Climate Change Characteristics — Radiological Incident — Cyber Attack 11111111111�� The following FEMA guides and reference documents were used to prepare this document: — FEMA 386-1: Getting Started: Building Support for Mitigation Planning.

The area predicted to flood during the I% annual chance flood, sometimes referred to as the "I 00-year"flood. — Hazard is defined as the natural or technological phenomenon, event, or physical condition that has the potential to cause property damage, infrastructure damage, other physical losses, and injuries and fatalities. — Mitigation is defined as actions taken to reduce or eliminate the long-term risk to life and property from hazards. Mitigation actions are intended to reduce the need for emergency response—as opposed to improving the ability to respond. — National Flood Insurance Program (NFIP), located within the U.S. Department of Homeland Security, Federal Emergency Management Agency(FEMA), is charged with preparing Flood courity, Mt�I tl 3 L fllscfi�cda,4� oca�� Mitigat'ar'i Strategy Jw"W&�'y 2(')26 ����)age Liii SECTION 1: INTRODUCTION Insurance Rate Maps, developing regulations to guide development, and providing insurance for flood damage. — Risk is defined as the potential losses associated with a hazard. Ideally,risk is defined in terms of expected probability and frequency of the hazard occurring,people and property exposed, and potential consequences.

This plan is an update to the 2020 Monroe County Multi-Jurisdictional Local Mitigation Strategy,which included participation from all jurisdictions involved in this plan update: City of Key Colony Beach, City of Key West, City of Layton, City of Marathon, and Islamorada Village of Islands. The previous plan was approved by FEMA in January 2021. This local mitigation strategy update involved a comprehensive review and update of each section of the existing plan and an assessment of the success of the County and participating jurisdictions in evaluating, monitoring and implementing the mitigation strategy outlined in their existing plans. Only the information and data still valid from the existing plans was carried forward as applicable into this update. The following requirements were addressed during the development of this County plan: — Consider changes in vulnerability due to action implementation; — Document success stories where mitigation efforts have proven effective; — Document areas where mitigation actions were not effective; — Document any new hazards that may arise or were previously overlooked; — Incorporate new data or studies on hazards and risks; — Incorporate new capabilities or changes in capabilities; — Incorporate growth and development-related changes to inventories; and — Incorporate new action recommendations or changes in action prioritization. Changes by plan section are summarized as follows: Section 1 provides an introduction to the Local Mitigation Strategy and remains largely unchanged from the previous update. Section 2 has been updated to reflect the 2025 planning process. This section describes the combined CRS and DMA compliant planning process the consultants used to facilitate the LMSWG through this LMS update and summarizes public outreach and agency coordination efforts that were conducted throughout the plan update process to meet the more rigorous requirements of the 2017 CRS Coordinator's Manual, in addition to DMA requirements. Detailed documentation of the planning process is compiled separately in Appendix B. This section also presents summary data on the status of mitigation actions from the 2020 strategy as a way to report on implementation progress of the 2020 update. Section 3 was updated to reflect the most up-to-date population, demographic, economic, and housing statistics. Details on land use and growth trends were updated to reflect recent changes in county-wide growth management strategies. Section 4 presents the hazard identification,hazard profiles, and vulnerability assessment findings. Section 4.2 provides a comparison of the hazards addressed in the 2023 State of Florida Enhanced Hazard Mitigation Plan and the 2020 Monroe County Multi-Jurisdictional Local Mitigation Strategy and provides the final decision made by the LMSWG as to which hazards should be included in this 2025 plan update. Updated data has been incorporated into each hazard profile.New vulnerability analyses were performed based on updated parcel data and population estimates. Where still relevant, data from the 2020 LMS was carried forward and incorporated into this section. In addition to the specific changes in hazard analyses identified in Section 4.3 and 4.5,the following items were also addressed in this 2025 plan update: GIS was used,to the extent data allowed,to analyze the priority hazards as part of the vulnerability assessment. li �iii .d ai,4 IIL...o III iii t lii ii iii*.m Strategy wi"m �&i. .: .6 SECTION 2: PLANNING PROCESS — The discussion on growth and development trends was enhanced utilizing 2023 American Community Survey data. — An effort was made to provide underserved communities and vulnerable populations with opportunities to participate in and contribute to the plan update process. Engagement opportunities were provided through the public survey, the plan website, and stakeholder coordination. Section 5 was updated to reflect current local regulatory, administrative, fiscal, and other capabilities, including changes that have occurred in the last five years. This section was also updated to include a more detailed discussion of continued compliance with the NFIP, including how each jurisdiction manages substantial damage and substantial improvement. Section 6 presents the mitigation strategy. The goals have been updated to reflect LMSWG and community priorities. This section also discusses the categories of mitigation alternatives considered and the process used to prioritize mitigation actions. For the LMS update,this process differs from the community's additional HMA prioritization process, which is detailed in Appendix D. This section also details completed and deleted actions from the 2020 strategy as a way to report on implementation progress and separate these removed actions from those that the county and participating jurisdictions will be pursuing moving forward. Section 7 presents the Mitigation Action Plan which presents all continued and new actions that will be pursued by the participating jurisdictions. Mitigation action status updates are provided for actions that were carried forward from the 2020 plan to explain progress made or barriers to implementation. Section 8 outlines the process for distribution, adoption, implementation, and maintenance of the plan. This section was updated to reflect recent and upcoming plan integration opportunities. Section 9 contains all applicable documentation of plan adoption from all participating communities. The plan annexes detail additional risk, capability,NFIP compliance, and mitigation strategy information for each participating community. ....................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................... mlll�i uuuummu�a uuuuuuuuuumm luuumuuu� ��N G um uu uuuuuuuuuuuuu uuuuuuuuuumm m uVluuuuuuuuuuuuu uuuuuuuuuuuum uuuuuuuuuuuum uuuuuuuuuu. The planning process for preparing the Monroe County Multi-Jurisdictional Local Mitigation Strategy was based on DMA planning requirements and FEMA's associated guidance. This guidance is structured around a four-phase process: Planning Process; Risk Assessment; 3 Mitigation Strategy; and 41 Plan Maintenance. Into this process,the planning consultant integrated a more detailed 10-step planning process used for FEMA's Community Rating System(CRS) and Flood Mitigation Assistance (FMA)programs. Thus,the modified 10-step process used for this plan meets the requirements of six major programs: FEMA's Hazard Mitigation Grant Program(HMGP); Building Resilient Infrastructure&Communities (BRIO) Program; CRS Program; FMA Program; Severe Repetitive Loss Program; and new flood control projects authorized by the U.S. Army Corps of Engineers (USAGE). Table 2.1 shows how the 10-step CRS planning process aligns with the four phases of hazard mitigation planning pursuant to the Disaster Mitigation Act of 2000. li �iii .d ai,4 IIL...o III iii t lii ii iii*.m Strategy wi"m �&i. .: .6 IIC: u e 8 SECTION 2: PLANNING PROCESS mulllll uu IIIIII iandIII�� IIIIIII IIIIII III)III IIIIIII IIIIIII IIIIIII �� � � ���� IIIIIII IIIIII IIIIIII IIIIIII III IIIIIII IIIIIII IIIIIII(IIIIIII WI�IoI.

PROCESS Planning Step 1:Organize to Prepare the Plan With the County's commitment to participate in the DMA planning process, community officials worked to establish the framework and organization for development of the plan. An initial meeting was held with key community representatives to discuss the organizational aspects of the plan development process. Monroe County Emergency Management led the effort to reorganize and coordinate for the plan update. Consultants from WSP assisted by facilitating the planning process and preparing the plan document. Planning Step 2:Involve the Public Public involvement in the development of the plan was sought using various methods, as detailed in Section 2.6. Planning Step 3: Coordinate The existing LMSWG, formed for development of the 2020 Monroe County Multi-Jurisdictional Local Mitigation Strategy, was reconvened for this plan update. Membership was updated where necessary to ensure each community had adequate representation from staff and stakeholders. More details on the LMSWG are provided in Section 2.4. Stakeholder coordination was incorporated into the formation of the LMSWG and was also sought through additional outreach methods. These efforts are detailed in Section 2.8 and documentation of additional stakeholder outreach is provided in Appendix B. Coordination with Other Community Planning Efforts and Hazard Mitigation Activities In addition to stakeholder involvement, coordination with other community planning efforts was also seen as paramount to the success of this plan. Mitigation planning involves identifying existing policies, tools, and actions that will reduce a community's risk and vulnerability to hazards. Communities in the Monroe County use a variety of planning mechanisms, such as comprehensive plans, subdivision regulations, building codes, and ordinances to guide growth and development. Integrating existing planning efforts, mitigation policies, and action strategies into this plan establishes a credible and comprehensive plan that ties into and supports other community programs.

Geographic information systems (GIS)were used to display, analyze, and quantify hazards and vulnerabilities. A draft of the risk and vulnerability assessment was made available on the plan website for the LMSWG, stakeholders, and the public to review and comment. li �iii .d ai,4 IIL...o III iii t lii ii iii*.m Strategy J a iii`.m U a iii. .: .6 SECTION 2: PLANNING PROCESS The LMSWG also conducted a capability assessment to review and document the planning area's current capabilities to mitigate risk from and vulnerability to hazards. By collecting information about existing government programs,policies, regulations, ordinances, and emergency plans,the LMSWG could assess those activities and measures already in place that contribute to mitigating some of the risks and vulnerabilities identified. A more detailed description of the risk assessment process and the results are included in Section 4 Risk Assessment. ....................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................... Planning Steps 6 and 7: Set Goals and Review Possible Activities WSP facilitated a discussion with the LMSWG to review and revise the planning goals and objectives and consider a comprehensive range of mitigation alternatives. The LMSWG also discussed a method of selecting and defending recommended mitigation actions using a series of selection criteria. This information is included in Section 6 Mitigation Strategy. Planning Step 8: Draft an Action Plan A complete first draft of the plan was prepared based on input from the LMSWG regarding the draft risk assessment and the goals and activities identified in Planning Steps 6 and 7. This draft was shared for LMSWG, stakeholder, and public review and comment via the plan website. LMSWG,public, and stakeholder comments were integrated into the final draft for FDEM and FEMA Region 4 to review and approve, contingent upon final adoption by all participating jurisdictions. ....................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................... 2.3.4 PHASE IV- PLAN '"O" Planning Step 9: Adopt the Plan To secure buy-in and officially implement the plan,the plan will be reviewed and adopted by all participating jurisdictions. Resolutions will be provided in Section 9. Planning Step 10: Implement,Evaluate and Revise the Plan Implementation and maintenance of the plan is critical to the overall success of hazard mitigation planning. Up to this point in the planning process,the LMSWG's efforts have been directed at researching data, coordinating input from participating entities, and developing mitigation actions. Section 8 Plan Maintenance provides an overview of the strategy for plan implementation and maintenance, outlines the method and schedule for monitoring,updating, and evaluating the plan, and discusses plan integration and how to continue public involvement. .......................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................

The LMSWG included 39 staff members and 43 outside stakeholders. Table 2.3 lists the membership of the LMSWG,the agencies and jurisdictions they represented, and members' attendance at meetings. Many of these representatives were involved in the development of the 2020 LMS and have since participated in regular plan reviews and maintenance. Additional staff from each jurisdiction were invited to participate, as needed,to ensure representation from each community. An effort was also made to involve additional stakeholders who could represent or coordinate with underserved communities and vulnerable populations. li �iii .d ai,4 IIL...ou III iii.tlii ii iii*.m Strategy wi"m u'��&i. .: .6 IIC:�I ��..III..III V c w.. `: d > > > > > > > V o U W �' a 0 IM - ° •� wM s m p_ E O u •— W _ i — c: — O •� •c6 can Q O '— DC v�i •`� N ca c6 E s O 4> >, 4, a '� U N c� v) N O j �-' �V) Q O '— U j • _ 0 0 0 o a w �, Q .o a� Q p o p _ m � � E � � � M �, � s � U � 4,J (, � a � E � � a � U � � � o ,0 .� •� o •� U V }' m o O o w cn m o U (D U O a) O _ O }, a) O U o U U •� o J U a to U D w LE to U a m a cn L% U U w U cUn D u O U V u a In +J U U o � o o C °' 4 °' i O U U U N •cNn •v0i N M N N O O N Q Q •M W Q v O o6 p 06 : v U U 0 0 Q 0 Q O U D z U m D a m D, J U V Q z a w W o E '� i Q +� i v) O s = 4-+ u N N — to 0) c a) M (3) i oC Q Q a o�c o = a a o o C a) (D Uv i 0 On s°LL Q U w i d N ;-> 1 0 v n .c6 U m U ,. s s s Z U U U U 0 Z m m m m Q N N U U u� O (p M M M M c >1 a >, p m ..

Agendas,minutes, and sign-in sheets for the LMSWG meetings are included in Appendix B. The meeting dates and topics discussed are summarized in Section 2.5 Meetings and Workshops. All LMSWG meetings were open to the public. The DMA planning regulations and guidance stress that each local government seeking FEMA approval of their mitigation plan must participate in the planning effort in the following ways: — Participate in the process as part of the LMSWG; — Detail where within the planning area the risk differs from that facing the entire area; — Identify potential mitigation actions; and — Formally adopt the plan. For the Monroe County LMSWG, "participation"meant the following: — Providing facilities for meetings; — Attending and participating in the LMSWG meetings; — Collecting and providing requested data(as available); — Providing an update on previously adopted mitigation actions; — Managing administrative details; — Making decisions on plan process and content; — Identifying mitigation actions for the plan; — Reviewing and providing comments on plan drafts; — Informing the public, local officials, and other interested parties about the planning process and providing opportunity for them to comment on the plan; — Coordinating and participating in the public input process; and — Coordinating the formal adoption of the plan by local governing bodies. Detailed summaries of LMSWG meetings are provided under Section 2.5 Meetings and Workshops, including meeting dates, locations, and topics discussed. During the planning process,the LMSWG members communicated through face-to-face meetings, email, and phone conversations. This continued communication ensured that coordination was ongoing throughout the entire planning process even though not all LMSWG members could be present at every meeting. Additionally, draft documents were distributed via the plan website so that the LMSWG members could easily access and review them and provide comments. ....................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................... u l ° u S0 Su 2 �N4 ��N G S A��N m WO The preparation of this plan required a series of meetings and workshops for facilitating discussion, gaining consensus, and initiating data collection efforts with local government staff, community officials, and other identified stakeholders. More importantly, the meetings and workshops prompted continuous input and feedback from relevant participants throughout the drafting stages of the plan. Table 2.4 summarizes the key meetings and workshops held by the LMSWG during the development of the plan. In many cases,routine discussions and additional meetings were held by local staff to accomplish planning tasks specific to their department or agency such as reporting on changes to local capabilities,updating the status of mitigation actions, and identifying new actions. This includes data collection meetings held between the planning team and the participating jurisdictions. These meetings were informal and are not documented here.

MISSION u 6 ��N VO uuuumumuu V ��'14 IIIIIIIIIIIIIII IIIIIIIIIIIIIII uuumuuu U uuuuuuuuuu III . An important component of any mitigation planning process is public participation. Individual citizen and community-based input provides the entire planning team with a greater understanding of local concerns and increases the likelihood of successfully implementing mitigation actions by developing community "buy-in" from those directly affected by the decisions of public officials. As citizens become more involved in decisions that affect their safety,they are more likely to gain a greater appreciation of the hazards present in their community and take the steps necessary to reduce their impact. Public awareness is a key component of any community's overall mitigation strategy aimed at making a home, neighborhood, school,business, or entire planning area safer from the potential effects of hazards. Public involvement in the development of the plan was sought using various methods including open public meetings, an interactive plan website, a public participation survey, and by making copies of draft plan documents available for public review online and at government offices. Additionally, all LMSWG meetings were made open to the public. All public meetings were advertised on the plan website,which was shared on local community websites. Where possible, advertisements were also posted on community websites and social media. Copies of meeting announcements are provided in Appendix B.

The public survey requested public input into the planning process,risk perception,past hazard events, and the identification of mitigation activities to lessen the risk and impact of future hazard events. The survey is shown in Appendix B. The survey was publicized online and made available on the plan website. In total, 126 survey responses were received. The following is a list of high-level summary results and analysis derived from survey responses: — Most responses came from residents of Unincorporated Monroe County, followed by Islamorada and Key West. — 86%of respondents have experienced a hazard event in the County in the past. Over two thirds of these experiences were related to hurricane and the remaining responses noted flooding events. Around 34% of respondents specifically mentioned Hurricane Irma. — There is significant concern among respondents about future hazard impacts. On average,respondents rated their concern at 4.4 out of 5. — Flood, Tropical Cyclone, and Sea Level Rise were rated the highest risk hazards. Wildfire,Drought, and Radiological Incident were rated the lowest risk hazards. — About 73% of respondents have taken actions to protect their home and neighborhood from hazards. Some respondents reported property protection measures such as elevating their home, altering li �iii .d ai,4 IIL...o III iii t lii ii iii*.m Strategy J a iii`.m U a iii. .: .6 SECTION 2: PLANNING PROCESS drainage patterns on their property, installing hurricane roof brackets for wind protection, or applying for acquisition.

The Florida Keys,which consist of an archipelago that sweeps southwesterly from southeastern Miami-Dade County for almost 150 miles, are located precariously between the Gulf of Mexico and the Atlantic Ocean. The area of Monroe County located on the Florida mainland is bordered by Collier County to the north and Miami-Dade County to the east. A location map is provided in Figure 3.1. The entire mainland portion of Monroe County is within Everglades National Park or Big Cypress National Preserves,with only 14 total residential buildings. The Florida Keys are characterized by long,narrow, and low-lying islands that average four to seven feet above mean sea level. The Florida Keys archipelago includes 74 named islands identified by the County's parcel data and detailed in Figure 3.2. The planning area comprises a total land area of approximately 982.2 square miles of land area. Large areas of submerged lands associated with parks and preserves also fall within Monroe County,bringing the County's total area to approximately 3,738 square miles.

They provide critical habitat for many plant and animal species that could not survive in other habitats. They are also critical for water management as they absorb and store vast quantities of storm water,helping reduce floods and recharge aquifers. Not only do wetlands store water like sponges, they also filter and clean water as well, absorbing toxins and other pollutants. Monroe County is home to many parks,preserves, beaches, and other natural areas. Mainland Monroe County is home to the western portion of Everglades National Park. There are also 11 state parks: — Curry Hammock State Park — Fort Zachary Taylor Historic State Park — John Pennekamp Coral Reef State Park — Bahia Honda State Park — Long Key State Park — Indian Key Historic State Park — Dagny Johnson Key Largo Hammock Botanical State Park — Florida Keys Overseas Heritage Trail — Windley Key Fossil Reef Geological State Park — San Pedro Underwater Archaeological Preserve State Park — Lignumvitae Key Botanical State Park The Monroe County Facilities Maintenance Department maintains 23 parks and beaches, covering more than 100 acres.

Figure 3.7 displays social vulnerability information for Monroe County by census tract according to 2022 data and analysis by the Centers for Disease Control and Prevention(CDC). The CDC's Social Vulnerability Index(SVI) indicates the relative vulnerability within census tracts based on 15 social factors: poverty,unemployment, income, education, age, disability,household composition,minority status, language, housing type, and transportation access. Higher social vulnerability is an indicator that a community may be limited in its ability to respond to and recover from hazard events. Therefore,using this SVI information can help the Region and jurisdictions to prioritize pre-disaster aid, allocate emergency preparedness and response resources, and plan for the provision of recovery support.

Table 3.10 and Table 3.11 provide details on housing characteristics in Monroe County and incorporated jurisdictions according to data from the 2020 Decennial Census and 2019-2023 ACS 5-Year Estimates. According to the 2020 Decennial Census,there are 53,961 housing units in Monroe County, of which 67.5 percent are occupied. Compared to the state, occupancy rates are lower across the county and all incorporated jurisdictions. Approximately 39.5% of occupied units are renter-occupied. A high percentage of renters is an indicator of higher pre-and post-disaster vulnerability because, according to III aii iiiri:)e courity, WSIII: IIM u.1 III ill ,iii iii ..lii ii w iii III Ill uu III III ii t iii ad aii°i Strategy J a iii*.m u a i a SECTION 3: PLANNING AREA PROFILE Cutter, et al. (2003),renters often do not have the financial resources of homeowners, are more transient, are less likely to have information about or access to recovery aid following a disaster and are more likely to require temporary shelter following a disaster. The City of Key West has the highest rate of renter- occupied housing, at 55.6%. Higher rates of home ownership in some jurisdictions, including Islamorada and unincorporated Monroe County,where owner-occupied housing rates are all above 70 percent,may indicate that more residents in these areas are able to implement certain types of mitigation in their homes. The housing growth rate since 2010 has been positive in Key West(2.3%), Marathon(3.9%), unincorporated Monroe County(4.6%), and Monroe County(2.3%) as a whole. Key Colony Beach has experienced the largest decrease in overall housing units at-29.9 percent, followed by Layton(-9.8%), and Islamorada(-1.1%). Nearly 58 percent of housing units in Monroe County are detached single family homes. The next most common housing type is 10 or more apartments,which make up 11.4 of all housing units. Apartments are followed by mobile homes,which make up 9.5% of the county's housing; mobile homes can be more vulnerable to certain hazards, such as tornadoes and wind storms, especially if they aren't secured with tie downs. Almost half of Monroe County's housing, 48.5 percent,was built prior to 1980. Age can indicate the potential vulnerability of a structure to certain hazards. For example,Monroe County first entered the National Flood Insurance Program in 1973. The Cities of Key Colony Beach, Key West, and Layton all entered the NFIP in 1971,however Marathon and Islamorada did not enter the NFIP until years later. This indicates that a significant portion of housing within Monroe County was not build to floodplain standards. miulVlilVli um uuumuum I � ������� a mum pool of i �uu inm mum umuu �'�'� � u uu'� uumm � puu pnn .m um II i� u�m um� ��. °°°° IIIIIII IIIIIII .

U.S. Route 1 (US 1), also known as the Overseas Highway, is the single road that forms the backbone of the transportation network in the Florida Keys and serves as the sole link to the Florida mainland. US 1 runs 126 miles from Florida City, in Miami Dade County,to Key West. The mostly two-lane highway is maintained by the Florida Department of Transportation. Along the route, there are 42 bridges totaling 19 miles. The Overseas Highway is a lifeline for the Keys, serving as both a highway and a"main street;"it drives the local economy by bringing food,materials, and tourists from the mainland. In addition to US 1,Monroe County maintains approximately 450 miles of roads, including 37 bridges. Card Sound Road—a toll road—serves as an alternate to US Highway 1 in some places. Mainland Monroe is primarily government owned parks and preserves and has few roads. The only County maintained road is Loop Road, a 16 mile loop off of US 41 that crosses the Miami Dade and Collier County lines. Key West,Marathon, Key Colony Beach, Islamorada, and Layton are all responsible for the streets within their boundaries that are not maintained by the state or the county. The County has two primary airports. Key West International Airport(EYW)is located within the Key West city limits, two miles east of the main commercial center. EYW is the primary passenger airport in the Keys and served more than 1.3 million passengers in 2023. Florida Keys/Marathon International Airport(MTH)is located within the Marathon city limits directly adjacent to US 1. MTH is a general aviation airport that currently does not have any scheduled passenger flights but does have charter air service. Both airports are self-supporting Enterprise Funds,which operate using money generated by rates and charges levied on airport tenants and users. The Airports Department operates the facilities and provides comprehensive aviation services. Bus service is provided by Greyhound to the Key Largo bus stop,the Marathon airport, and the Key West Bus Station. Key West Transit provides public bus service with five routes in the City of Key West and one route for the Lower Keys Shuttle,traveling between Key West and Marathon. Miami-Dade Transit provides the Dade-Monroe Express between Florida City and Marathon. ....................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................... 3.52 UTILITIES Electric power for the County is provided by the Florida Keys Electric Cooperative (FKEC) from the Upper Keys (Miami-Dade County Line)to Marathon at the Seven Mile Bridge and by Keys Energy Services KEYS) from the Seven Mile Bridge to Key West. The electric transmission lines in the county are above-ground, and transmission poles are located in the water at bridge crossings between keys. FKEC is a member-owned not-for-profit electric utility. The cooperative brings power from the mainland to the Florida Keys to serve approximately 33,000 accounts via a 138,000-volt transmission line. The transmission line is jointly owned by FKEC and KEYS,with FKEC responsible for maintenance in their territory. FKEC purchases nearly 100 percent of its power from Florida Power&Light, although generators in Marathon and two solar arrays also contribute to power supply. FKEC operates 6 substations and maintains over 800-miles of distribution power lines. Keys Energy Services is a municipal owned public utility headquartered in Key West serving more than 28,000 customers. KEYS purchases all of its power through Florida Municipal Power Agency(FMPA) and imports the power from the mainland via the 13 8,000 volt transmission line.

P SECTION 3: PLANNING AREA PROFILE megawatts of generation on Stock Island. The local generation is used to meet peak loads and for emergency backup in the event of loss of the transmission line. KEYS operates 9 substations and maintains over 900 miles of distribution power lines (340 miles three phase equivalent). Water service in the Florida Keys is provided by the Florida Keys Aqueduct Authority(FKAA), an independent state agency with the primary purpose and function to obtain, supply, and distribute an adequate water supple to the Florida Keys. FKAA provides potable water across the County along with reclaimed water and wastewater services in select areas. In total,FKAA delivers approximately 16.5 million gallons of drinking water per day. The Authority manages the infrastructure to supple water, including a pipeline that originates in Florida City(Miami-Dade County)bringing water from the Biscayne Aquifer. The main pipeline that connects the upper keys is laid underwater; some distribution pipelines, however, are connected to roads and bridges and may be vulnerable to washout. FKAA additionally operates two reverse osmosis emergency water treatment plants to provide an alternate source when water cannot be supplied through the pipeline. FKAA is required to meet or exceed the latest edition of the Florida Building Code when building or renovating its facilities; it also complies with the minimum design standards for flood protection of water and wastewater infrastructure set by the Florida Department of Environmental Protection. ....................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................... 3.6 uuuuuuum IIkq a um A��Nuuuuu uuuuuuuu II uuuuuuuu uuumum uuuuu mu 1 uuuuuuu C Uumi IIII uuuuuuu uuuuuuuuuuuuuu uuuuuuuu uuuuuuuuuuuuu uuuuuuuuum. 14uuuuuuuutli uuuuuuuuuuuum A��� Monroe County and each of its jurisdictions use a comprehensive land use plan to guide their growth. A community's comprehensive plan and future land use map help determine development decisions and indicate where growth can be expected to occur based on land suitability and the community's overall vision and priorities. In 1975,the Florida Keys were designated as an Area of Critical State Concern by the Administration Commission and then by the Florida Legislature in 1979. This designation is intended to protect environmental and natural resources of regional and statewide importance,historical archaeological resources, and major public facilities and public investments; these resources include the only coral reef system in North America, and the third largest in the world, and one of the most ecologically diverse ecosystems in the United States. Due to this designation, federal and state involvement in the County's land use planning is extensive. ....................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................... MONROE C Land use in Monroe County is managed by the Monroe County Planning and Environmental Resources Department. The department has four offices: Comprehensive Planning, Current Planning, Environmental Resources, and Marine Resources; floodplain management also falls within this department. Across these offices,the department is responsible for the administration of the County's comprehensive plan and land development regulations, including processing amendments to the plan(comprehensive planning). Additionally, the department reviews development proposals for compliance with the plan, including environmental compliance (current planning). The County's adopted comprehensive plan,most recently updated in 2010 to plan through the year 2030, guides future growth and community development. Monroe County's Comprehensive Plan states that"Monroe County shall manage future growth to enhance the quality of life, ensure the safety of County residents and visitors, and protect valuable natural resources."It designates the following future land use categories to guide growth within the county: — Agriculture — Mixed Use/Commercial Fishing — Airport District — Mainland Native III .III ill .iii iii ..lii ii iii III Ill ou III III iii t iii atiii aii°m Strategy Jaiir'i u a�i a 2,02,6 SECTION 3: PLANNING AREA PROFILE — Conservation — Public Buildings/Lands — Commercial — Public Facilities — Education — Recreation — Industrial — Residential Conservation — Institutional — Residential High — Military — Residential Low — Mixed Use/Commercial — Residential Medium Monroe County's future land use map is available via an online GIS application. .......................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................

CITY OFL The City of Layton updated its comprehensive plan in 2016. Through this plan,the city sets out to "maintain the residential character of Layton,manage the rate of development and population growth to provide small-town ambiance, improve quality of life for residents..." The comprehensive plan provides an existing land use map (as of 2007)as well as a future land use map. These maps, shown side-by-side in Figure 3.10 and Figure 3.10 are almost identical—meaning that the city intends to maintain the current development pattern. Layton concentrates commercial and institutional development along the U.S. 1 Corridor and reserves the area behind these commercial/institutional spaces for single-family homes. It divides future land uses into four categories: Single-family,Multi-family, Recreation, and Conservation.

CITY OF MARATHON The City of Marathon passed its most recent comprehensive plan in 2005. The comprehensive plan seeks to direct future growth towards "lands which are inherently most suitable for development" and it promotes "conservation,preservation, and protection of environmentally lands." Through the future land use map,the city primarily encourages mixed use development along the U.S. 1 corridor and reserves areas for conservation and recreation. It also favors medium and high-density residential development, rather than just low residential. Future land use categories include: — Airport — Conservation — Industrial — Mixed Use Commercial — Public — Recreation — Residential High — Residential Medium — Residential Low The City's future land use map is available via an online GIS application on the City website. .......................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................

The Monroe County Rate of Growth Ordinance(ROGO) controls the number of dwelling units—both permanent and seasonal—that can be permitted in Monroe County and incorporated municipalities. The ROGO was initially adopted in 1992 as a response to the inability of the road network to accommodate a large-scale hurricane evacuation in a timely fashion. During the initial evacuation study, a series of complex models was developed to determine the number of additional dwelling units that could be permitted without exceeding a 24 hour evacuation from the Keys. As a result, a tool was developed to equitably distribute—geographically and over time—the remaining number of permits available. Based on the supply of vacant buildable lots,the ROGO distributes a pre-determined number of allocations for new residential permits by ROGO Year—generally from July 13'of one year through July 12'of the next year. To further address concerns of carrying capacity,the County implemented the tier system. This system designates all land outside of mainland Monroe into three general categories for purposes of its land acquisition program and smart growth. Both systems recognize the finite limits of the carrying capacity of both the natural and man-made systems in the Keys. Their goal is to ensure public safety through the ability to maintain a hurricane evacuation clearance time. Both the ROGO and Tier III .III ill .iii iii ..lii ii iii III IIL...ou III III iii t iii atiii ar''I Strategy Jaiir'iu ai SECTION 3: PLANNING AREA PROFILE System exclude the Ocean Reef Club planned development in Key Largo based on the Ocean Reef Club Vested Development rights letter. The three tiers are as follows: - Tier I: Natural Areas - Tier II: Transitional and Sprawl Reduction Area(on Big Pine Key and No Name Key, only) - Tier III: Infill Area; includes a special protection area as a subset(Tier III-A) Under the Rate of Growth Ordinance,the number of permits to be allocated between July 13'2013 through July 13th 2023 was to not exceed 1,970. These allocations were to be divided yearly and across market rate units, affordable housing units,mobile homes, and institutional residential units. The County required at least 20 percent of yearly allocations to be affordable units. Annual permits were also divided between three subareas: Upper Keys, Lower Keys, and Big Pine Key/No Name Key. On February 10, 2020,the county adopted Ordinance No. 006-2020 amending section 13 8-24 of the Monroe County Land Development Code. Through this adoption,the County extended the ROGO time period through 2026. In so doing,the number of permits available annually was reduced. Table 3.12 below illustrated the permits to be made available under this new ordinance amendment.

The predominant form of non-residential development in the Keys is commercial,mainly retail trade and services; this includes tourism related development such as marinas and restaurants. Non-residential development is also controlled to maintain a balance of land uses between residential and commercial. The Non-residential Rate of Growth Ordinance (NROGO) limits the square footage of new commercial development to 239 square feet per each new residential permit issued. In unincorporated Monroe County,this means a maximum of 47,083 square feet of floor area per NROGO year. This is also to be distributed across the same three subareas as the ROGO permits.

The Keys attract both seasonal residents and short-term visitors with an amenable climate and many recreational opportunities. The economy is dominated by tourism;the service sector,primarily hospitality,is the largest segment of the private sector followed by retail trade. As such an important piece of the economy, the tourism industry supplements the tax base in Monroe County. A major hurricane or other disaster event that keeps visitors away will lead to reduced revenue associated with the Bed Tax, Sales Tax, and Infrastructure Tax. ....................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................... 3.7 7 WAGE,S AND EMPLOYMENT Per the 2023 ACS 5-Year Estimates,the median household income for Monroe County was $82,430, which exceeds the state's median household income ($71,711). Household income is higher in each Monroe County jurisdiction than in the state. Income is highest in Key Colony Beach and Islamorada and lowest in Layton. Compared to the state, a smaller portion of the population is living below the poverty line in the County and all jurisdictions,but more of the population lacks health insurance across the County and in all incorporated jurisdictions except Islamorada. Overall,Monroe County and its jurisdictions experience higher household incomes and lower unemployment and poverty rates than the state of Florida.

It describes how the County met the following requirements from the 10-step planning process: — Planning Step 4: Assess the Hazard — Planning Step 5: Assess the Problem As defined by FEMA,risk is a combination of hazard,vulnerability, and exposure. "It is the impact that a hazard would have on people, services, facilities, and structures in a community and refers to the likelihood of a hazard event resulting in an adverse condition that causes injury or damage." This hazard risk assessment covers all of Monroe County, including the unincorporated county and all incorporated jurisdictions participating in this plan. The risk assessment process identifies and profiles relevant hazards and assesses the exposure of lives, property, and infrastructure to these hazards. The process allows for a better understanding of the potential risk to natural and technological hazards in the county and provides a framework for developing and prioritizing mitigation actions to reduce risk from future hazard events. This risk assessment followed the methodology described in the FEMA publication Understanding Your Risks Identifying Hazards and Estimating Losses (FEMA 386-2, 2002),which breaks the assessment down to a four-step process: n� r e III:IIL...

Significance was measured in general terms and focused on key criteria such as frequency and resulting damage,which includes deaths and injuries, as well as property and economic damage. One key resource in this effort was the National Oceanic and Atmospheric Administration(NOAA)'s National Center for Environmental Information(NCEI),which has been tracking various types of severe weather since 1950. Their Storm Events Database contains an archive by county of destructive storm or weather data and information which includes local, intense and damaging events. NCEI receives storm data from the National Weather Service(NWS),which compiles their information from a variety of sources, including but not limited to: county, state and federal emergency management officials; local law enforcement officials; SkyWarn spotters;NWS damage surveys; newspaper clipping services; the insurance industry and the general public, among others. The NCEI database contains 413 records of severe weather events that occurred in Monroe County in the 25-year period from 2000 through 2024.

Federal and/or state disaster declarations may be granted when the Governor certifies that the combined local, county and state resources are insufficient, and that the situation is beyond their recovery capabilities. When the local government's capacity has been surpassed, a state disaster declaration may be issued, allowing for the provision of state assistance. If the disaster is so severe that both the local and state government capacities are exceeded, a federal emergency or disaster declaration may be issued allowing for the provision of federal assistance. — Emergency declarations: When federal assistance is needed,the President of the United States can declare an emergency for any occasion or disaster. Emergency declarations aide State and local efforts in providing emergency services that help protect human lives. — Major disaster declarations: When a local government's capacity has been surpassed, a state disaster declaration may be issued, allowing for the provision of state assistance. Federal and/or state disaster declarations may be granted when the Governor certifies that the combined local, county, and state resources are insufficient, and the situation is beyond their recovery capabilities. Records of designated counties for FEMA major disaster declarations start in 1964. Since then, Florida has been designated in 88 major disaster declarations, and Monroe County,has been designated in 27 major disaster declarations, as detailed in Table 4.3, and 18 emergency declarations, as detailed in Table 4.4. °°° Illlllhlllllll °°° IIIIIII IIIIIII IIIIII IIIIIII IIIIIII IIIIIII Illilll IIIIIII IIIIIII° IIIIIII IIIIIII tlllilll IIIIIII IIImoIIIIIIIvIIIPoe CouIIIIIII,Iltly Disaster# Dec.Date Incident Type Event Title 4834 10/11/2024 Hurricane Hurricane Milton 4828 9/28/2024 Hurricane Hurricane Helene 4806 8/10/2024 Tropical Storm Hurricane Debby 4673 9/29/2022 Hurricane Hurricane Ian 4486 3/25/2020 Biological COVID-19 Pandemic 4337 9/10/2017 Hurricane Hurricane Irma 4084 10/18/2012 Hurricane Hurricane Isaac 1785 8/24/2008 Tropical Storm Tropical Storm Fay 1609 10/24/2005 Hurricane Hurricane Wilma 1602 8/28/2005 Hurricane Hurricane Katrina 1595 7/10/2005 Hurricane Hurricane Dennis 1551 9/16/2004 Hurricane Hurricane Ivan 1545 9/4/2004 Hurricane Hurricane Frances 1539 8/13/2004 Severe Storm(s) Hurricane Charley and Tropical Storm Bonnie 1359 2/5/2001 Freeze Severe freeze 1345 10/4/2000 Severe Storm(s) Heavy rains and flooding 1306 10/20/1999 Hurricane Hurricane Irene IIP �i �i .��i � � I i�l tii'i i*.m Strategy y a iii`.m U a iii. .: .6 IIC:.)Eigei Ll.

Natural Hazards The 2021 Monroe County plan and 2023 State plan addressed this Flood Yes hazard.As a coastal county,over 99 percent of the county is within the 100-year-flood plain,and the county is also vulnerable to localized and stormwater flooding. Both the 2021 Monroe County plan and the 2023 State plan Tropical Cyclones Yes addressed Tropical Cyclones.Since 1965,the county has received 16 Major Disaster declarations from FEMA for Hurricanes/Tropical storms. The 2021 Monroe County plan profiled these hazards separately. Severe Storms and Yes From 2000 to 2024,the County experienced 225 thunderstorm and Tornadoes tornado events(including waterspouts)causing over$5.5m in damages. The 2021 Monroe County plan as well as the 2023 State plan Wildfire Yes addressed this hazard.Although NCEI reports only 1 wildfire in Monroe County,the State plan reports parts of mainland Monroe have moderate to high burn probability. The 2021 Monroe County LMS and the 2023 State Plan addressed Coastal Erosion Yes this hazard.The 2024 State Critically Eroded Beaches Report identified 13 critically eroded beaches in the middle and lower keys tota I ly 15.02 m i I es. Drought as included in both the 2021 Monroe County LMS and the Drought Yes 2023 State Plan. NCEI reports 12 instances of drought in the county; the LMSWG decided to continue to evaluate drought in this plan update. Sea Level Rise was addressed in the 2021 Monroe County LMS as Sea Level Rise Yes well as the 2023 State plan. NOAA's Sea Level Rise Viewer shows the County will experience impacts from even just one foot of sea level rise. The 2021 Monroe County LMS and the 2023 State Plan addressed Extreme Heat Yes this hazard.Although NCEI reports zero instances of extreme heat in the county,the LMSWG decided to include it in this plan update. This hazard was not included in the 2021 Monroe County LMS. Sinkhole No According the 2023 State H M P, Monroe County has a low susceptibility to sinkholes,therefore the LMSWG chose to not include sinkholes in this plan update. Winter storms and freezes were not included in the 2021 LMS. Winter Weather No Although there have been some instances of low wind chill in the Keys,the LMSWG noted that the Keys are generally not at risk to winter weather.

Ilf:���)E g ���..111 SECTION 4: HAZARD IDENTIFICATION&RISK ASSESSMENT Included in Hazard this LMS Explanation for Decision update? Earthquake was not included as a hazard in the 2021 Monroe County LMS. Earthquakes are very rare in the State,the peak ground acceleration (PGA)with a 10% probability of exceedance in Earthquake No 50 years is 0%gravity-the lowest potential for seismic ground shaking.As FEMA recommends earthquakes only be evaluated in areas with PGA of 3%or more,this hazard was excluded from the plan update. While there is some tsunami risk for low-elevation (less than 15 feet Tsunami No above mean high tide),they are extremely rare in the Florida Keys. The state HMP concludes the probability of future tsunamis is low. Technological Hazards The 2021 Monroe County LMS and the 2023 State Plan addressed Radiological Yes this hazard. Due to the County's proximity to the Turkey Point Incident Nuclear Generating Station,the LMSWG decided to include it in this update. The 2021 Monroe County LMS and the 2023 State Plan addressed Cyber Attacks Yes this hazard.The LMSWG determined that because of recent events, it should be included in this update. Hazardous No This hazard was not included in the previous Monroe County LMS Materials Incident and not suggested by the LMSWG for inclusion in this update. This hazard was not included in the previous Monroe County LMS. Transportation No The LMSWG discussed this hazard and the consequences of Incident transportation incidents on the Keys. However,this hazard was ultimately not included in this update. Agricultural No This hazard was not included in the previous Monroe County LMS Disruption and not suggested by the LMSWG for inclusion in this update. This hazard was not included in the previous Monroe County LMS Human Health No and not suggested by the LMSWG for inclusion in this update. Incident Health hazards are addressed by public health departments and emergency operations planning. Harmful Algal No This hazard was not included in the previous Monroe County LMS Bloom and not suggested by the LMSWG for inclusion in this update. Domestic Security This hazard was not included in the previous Monroe County LMS Incident No and not suggested by the LMSWG for inclusion in this update. These threats are addressed by emergency operations planning. Mass Migration No This hazard was not included in the previous Monroe County LMS and not suggested by the LMSWG for inclusion in this update. This hazard was not included in the previous Monroe County LMS Civil Disturbance No and not suggested by the LMSWG for inclusion in this update. These threats are addressed by emergency operations planning. Dam Failure No The 2023 State Plan reported there were no high or significant hazard dams in Monroe County. Space Weather No This hazard was not included in the previous Monroe County LMS and not suggested by the LMSWG for inclusion in this update.

Each hazard was evaluated to determine its probability of future occurrence and potential impact. A vulnerability assessment was conducted for each hazard using either quantitative or qualitative methods depending on the available data,to determine its potential to cause significant human and/or monetary losses. A consequence analysis was also completed for each hazard. Each hazard is profiled in the following format: This section provides a description of the hazard, including discussion of its speed of onset and duration, as well as any secondary effects followed by details specific to the Monroe County planning area. This section includes information on the hazard's physical extent,with mapped boundaries where applicable. This section includes information on the hazard extent in terms of magnitude and describes how the severity of the hazard can be measured. Where available, the most severe event on record is used as a frame of reference. This section contains information on historical events, including the location and consequences of known past events on record within or near the Monroe County planning area. C This section gauges the likelihood of future occurrences based on past events and existing data. The frequency is determined by dividing the number of events observed by the number of years on record and multiplying by 100. This provides the percent chance of the event happening in any given year according to historical occurrence (e.g. 10 winter storm events over a 30-year period equates to a 33 percent chance of experiencing a severe winter storm in any given year). Where applicable,this section discusses how climate change may or may not influence the risk posed by the hazard on the planning area in the future. This section quantifies,to the extent feasible using best available data, assets at risk to natural hazards and potential loss estimates. People,properties and critical facilities, and environmental assets that are vulnerable to the hazard are identified. Future development is also discussed in this section, including how exposure to the hazard may change in the future or how development may affect hazard risk. The vulnerability assessments followed the methodology described in the FEMA publication Understanding Your Risks Identifying Hazards and Estimating Losses (August 2001). The vulnerability assessment first describes the total vulnerability and values at risk and then discusses vulnerability by hazard. Data used to support this assessment included the following: li �iii .d ai,4 IIL...o III iii.tlii ii iii*.m Strategy J a iii`.m U a iii'. .: .6 IIC:.)'I'g i 53 SECTION 4: HAZARD IDENTIFICATION&RISK ASSESSMENT — GIS datasets, including building footprints,topography, aerial photography, and transportation layers; — Hazard layer GIS datasets from state and federal agencies; — Written descriptions of inventory and risks provided by the 2023 Florida Enhanced State Hazard Mitigation Plan; — Written descriptions of inventory and risks provided by the 2020 Monroe County Local Mitigation Strategy and other relevant documents including the 2019 Critically Eroded Beaches Report and the Regional Climate Action Plan; — Exposure and vulnerability estimates derived using local parcel and building data; and — Crop insurance claims by cause from USDA's Risk Management Agency. Two distinct risk assessment methodologies were used in the formation of the vulnerability assessment. The first consists of a quantitative analysis that relies upon best available data and technology,while the second approach consists of a qualitative analysis that relies on local knowledge and rational decision making. The quantitative analysis involved the use of FEMA's Hazus-MH, a nationally applicable standardized set of models for estimating potential losses from earthquakes, floods, and hurricanes. Hazus uses a statistical approach and mathematical modeling of risk to predict a hazard's frequency of occurrence and estimated impacts based on recorded or historic damage information. The Hazus risk assessment methodology is parametric, in that distinct hazard and inventory parameters such as wind speed and building type were modeled using the Hazus software to determine the impact on the built environment. Monroe County's GIS-based risk assessment was completed using data collected from local, regional and national sources that included Monroe County, Florida DEM, and FEMA. Vulnerability can be quantified in those instances where there is a known,identified hazard area, such as a mapped floodplain. In these instances,the numbers and types of buildings subject to the identified hazard can be counted and their values tabulated. Other information can be collected regarding the hazard area, such as the location of critical facilities, historic structures, and valued natural resources (e.g., an identified wetland or endangered species habitat). Together, this information conveys the vulnerability of that area to that hazard. Related hazards or hazards with cascading impacts are noted in this section. Changes in development that may affect exposure,vulnerability, or the hazard occurrence are described. ��::: ��::: S III Specific problems that can be addressed through mitigation are summarized in this section. The conclusions drawn from the hazard profiling and vulnerability assessment process can be used to prioritize all potential hazards to the Monroe County planning area. The Priority Risk Index(PRI)was applied for this purpose because it provides a standardized numerical value so that hazards can be compared against one another(the higher the PRI value, the greater the hazard risk). PRI values are obtained by assigning varying degrees of risk to five categories for each hazard(probability,impact, spatial extent, warning time, and duration). Each degree of risk was assigned a value (1 to 4) and a weighting factor as summarized in Table 4.6. PRI ratings by category for the planning area as a whole are provided throughout each hazard profile. Ratings specific to each jurisdiction are provided at the end of each hazard profile. The results of the risk assessment and overall PRI scoring are provided in Section 4.6 Conclusions on Hazard Risk. li �iii .d ai,4 IIL...o III iii t lii ii iii*.m Strategy wi"m �&i. .: .6 SECTION 4: HAZARD IDENTIFICATION&RISK ASSESSMENT "'"""' IIIIIII IIIIIII 4, IIIIIII IIIIIII IIIIIII IIIII`tyIIIIIII IIIIIII IIIIIII P""' RISK ASSESSMENT LEVEL DEGREE OF RISK CRITERIA INDEX WEIGHT CATEGORY PROBABILITY UNLIKELY LESS THAN 1%ANNUAL PROBABILITY 1 What is the likelihood of a POSSIBLE BETWEEN 1&10%ANNUAL PROBABILITY 2 30% hazard event LIKELY BETWEEN 10&100%ANNUAL PROBABILITY 3 occurring in a given ear?

Hazard ProbabilityImpact Spatial WarningTime Duration PRE P Extent Score Coastal Erosion Likely Limited Moderate Less than 24 hrs Less than 1 week 2.5 Coastal erosion is a process whereby large storms, flooding, strong wave action, sea level rise, and human activities, such as inappropriate land use, alterations, and shore protection structures,wear away the beaches and bluffs along the coast. Erosion undermines and often destroys homes,businesses, and public infrastructure and can have long-term economic and social consequences. According to NOAA, coastal erosion is responsible for approximately$500 million per year in coastal property loss in the United States, including damage to structures and loss of land. To mitigate coastal erosion, the federal government subsidizes beach nourishment projects and other shoreline erosion control measures. Since 2018,the federal government has spent more than$770 million for emergency beach nourishment projects in Florida, Georgia, and the Carolinas. Coastal erosion has both natural causes and causes related to human activities. Gradual coastal erosion and accretion results naturally from the impacts of tidal longshore currents. Severe coastal erosion can occur over a short period when the state is impacted by hurricanes,tropical storms and other weather systems. Sand is continually removed by longshore currents in some areas,but it is also continually replaced by sand carried in by the same type of currents. Structures such as piers or sea walls,j etties, and navigational inlets may interrupt the movement of sand. Sand can become "trapped" in one place by these types of structures. The currents will, of course, continue to flow,though depleted of sand trapped elsewhere. With significant amounts of sand trapped in the system,the continuing motion of currents (now deficient in sand)results in erosion. In this way,human construction activities that result in the unnatural trapping of sand have the potential to result in significant coastal erosion. Erosion rates and potential impacts are highly localized. Severe storms can remove wide beaches, along with substantial dunes, in a single event. In undeveloped areas,these high recession rates are not likely to cause significant concern,but in some heavily populated locations, one or two feet of erosion may be considered catastrophic (NOAA, 2014). Estuaries are partially enclosed, coastal water bodies where freshwater meats saltwater from the ocean. They are influenced by tides but still protected from the full force of ocean waves. Estuaries are often referred to as bays or sounds. Estuarine coastlines can experience erosion through short-term processes, such as tides, storms,wind, and boat wakes, as well as long-term processes, such as sea level rise. Many variables determine the rate of estuarine erosion including shoreline type, geographic location and size of the associated estuary, the type and abundance of vegetation, and the frequency and intensity of storms. Warning Time: 1 —More than 24 hours Duration: 3—Less than I week Erosion can occur along any shoreline in the county. In Monroe County, erosion is typically caused by coastal tides, ocean currents, and especially storm events such as hurricanes and tropical storms. Erosion li �iii .d ai,4 IIL...o III iii t lii ii iii*.m Strategy J a iii`.m U a iii. .: .6 IIC:.)Eige 5 SECTION 4: HAZARD IDENTIFICATION&RISK ASSESSMENT rates are dependent on many characteristics, including soil type. The Lower Keys,having more calcium carbonate beaches, are more susceptible to erosion than the Upper and Middle Keys. In fact,the Upper Keys do not have naturally occurring beaches are thus less susceptible to erosion. The Florida Department of Environmental Protection(DEP)regularly monitors Florida's coastline and determines geographic areas of the state that are at high risk to erosion. DEP defines a critical erosion area as: "a segment of shoreline where natural processes or human activity have caused or contributed to erosion and recession of beach or dune system to such a degree that upland development, recreational interest, wildlife habitat, or important cultural resources are threatened or lost. Critical erosion areas may also include peripheral segments or gaps between identified critical erosion areas which, although they may be stable or slightly erosional now, their inclusion is necessary for continuity of management of the coastal system or for the design integrity of adjacent beach management projects." Per DEP's Strategic Beach Management Plan,there are 36.3 miles of beaches in the Florida Keys Region, from just south of Key Biscayne(in Miami-Dade County)to the Dry Tortugas (in Monroe County). Of these beaches, 15.02 miles are critically eroded, all in the Monroe County portion of the region. Table 4.9 below lists the locations of these critically eroded beaches as reported in the 2024 Critically Eroded Beaches report. These shorelines are also mapped in Figure 4.1. Mainland beaches of Key McLaughlin and Cable Sable fronting the Gulf of Mexico are not included in the list below due to insufficient data,however both beaches did sustain severe erosion during Hurricane Wilma in 2005. The Distal Sand keys,west of Key West,were also left out of the below assessment due to insufficient evidence. The Fills, in Islamorada between mile marker 77 and 79,have experienced significant erosion and received funding in the past to address these issues. Additionally, erosion has impacted Key's Energy infrastructure. Erosion around utility and transmission poles has led to the removal and relocation of such infrastructure. It should be noted that many of the designated critically eroded beaches have undergone some level of restoration. The shorelines where these beach restoration projects have taken place have improved compared to their pre-project condition,however,these shorelines retain their critical erosion designation in order to retain their state of Florida funding eligibility for long term management and beach project maintenance and monitoring. More details on the methods used to determine the location of critically eroded beaches and the impacts of such erosion on individual locations may be found in Florida DEP's Critically Eroded Beaches Report.

Erosion rates can vary significantly across the county due to several factors including fetch, shoreline orientation, and soil composition. To account for these variations, long-term erosion can also be measured by land cover changes and increases in open water. While a small fraction of the shoreline may exhibit accretion over a short period of time, cumulative impacts can still indicate an overall loss of estuarine coastline and marsh habitat.

Only emergent wetlands and all development types were the only land cover areas to see an increase during this time period. Increases in developed land likely result in increased impervious surfaces,which may increase stormwater runoff, alter drainage patterns, and further exacerbate erosion and flood issues. In terms of the magnitude of impacts, erosion may cause property damage when severe but is unlikely to cause injury or death.

Erosion is typically an ongoing process;however, it can be intensified and accelerated during storm events,particularly hurricane storm tides. Per an examination of event narratives in NCEI records for hurricanes,tropical storms, storm surges, and coastal floods,the following instances of major erosion are noted in Monroe County: August 17,2008 (Tropical Storm)—Tropical Storm Fay crossed through the Lower Florida Keys of Monroe County during the evening of August 18. Damage and preparedness costs to government facilities and infrastructure totaled 2.8 million dollars,with about one million dollars due to coastal flooding damage to roads, and 200,000 dollars due to erosion. September 9,2008 (Tropical Storm)—Hurricane Ike passed well southwest of the Florida Keys and into the Gulf of Mexico. However, Ike's large wind field produced tropical storm force winds during September 9-10, 2008. Total damage to government property in Monroe County was estimated at$13.5 million dollars. Approximately $1.2 million damage in debris removal and erosion occurred county-wide due to storm surge flooding,with$2.6 million estimated from combined effects from wind and wind- blown rain. Erosion occurred to the causeways surrounding the Card Sound Bridge. November 7,2020 (Tropical Storm)—Tropical Storm Eta passed northwest through the middle Florida Keys on November 8 through 9, 2020. Primary impacts from wind occurred as result of a primary rain band which drifted very slowly north through the Upper Florida Keys. Peak wind gusts were mostly in the 50 to 60 mph range, downing trees and large tree limbs,utility lines, and a billboard. One residence was destroyed by a fallen tree resulting in 1 minor injury. Two other residential structures were significantly damaged, with three inaccessible due to blocked streets. About 20 separate power outages affected about 1,000 customers,mostly in Key Largo. Storm Surge flooding was generally in the 1.5 to 2.5 foot range,producing significant street flooding in oceanside Key Largo neighborhoods. The northbound right-of-way was damaged including major erosion, loss of riprap, and about 3,000 feet of fencing along northbound U.S. Highway 1 along the west end of Barnes Sound and Manatee Bay. Minor over wash occurred in the middle Florida Keys at Key Colony Beach, along with yard and dock flooding along the Florida Bay side of Marathon. Widespread rainfall of 3.5 to over 8 inches was measured throughout the Keys,with the highest totals in Key Largo. Damages were estimated near$500K due to mostly from homes damaged by falling trees and tree limbs, as well as utility damage. Storm Surge damage near$1 OOK due to wave action on top of a minor storm surge to the U.S Highway 1 right-of-way. July 5,2021 (Tropical Storm)—Tropical Storm Elsa moved north-northwest from western Cuba,through the western Straits of Florida, and passed between the Marquesas Keys and Dry Tortugas into the southeast Gulf of Mexico. Numerous rain bands moved northwest and north through the Lower and Middle Florida Keys,with strong tropical-storm-force wind gusts measured near Key West from the evening of July 5th through the afternoon of July 6th. Maximum winds over the Florida Keys of Monroe County were recorded at 52 mph with gusts to 70 mph at Key West. Wind impacts were confined to damage to trees and utility lines,mostly in Key West proper. No storm surge was recorded in the Florida Keys, however the onshore southerly winds raised water levels just below 1.0 foot above normal at Key West closer to low astronomical tide. Moderate oceanside beach erosion occurred at Key West along with over wash from heavy wave action. Storm total rainfall up to near 7.5 inches resulted in brief but significant street flooding in Key West midday on July 6th. The Strategic Beach Management Plan report notes the following storms caused erosion of County beaches: Hurricane Andrew(1992;Upper Keys) li �iii .d ai,4 IIL...o III iii t lii ii iii*.m Strategy wi"m �&i. .: .6 SECTION 4: HAZARD IDENTIFICATION&RISK ASSESSMENT — Hurricane Georges (1998; Upper,Middle, and Lower Keys) — Hurricane Irene(1999; Middle and Lower Keys) — Hurricanes Rita and Wilma(2005; Upper,Middle, and Lower Keys) — Tropical Storm Fay(2008) — Hurricane Isaac(2012) — Hurricane Irma(2017) Hurricane Irma caused moderate to severe erosion along most beaches in the Middle and Lower Florida Keys. As reported in the Hurricane Irma Post-Storm Report, as Irma made landfall in the Keys with the eye around Cudj oe Key, areas within and to the east of the eye sustained major beach and dune erosion, including complete destruction of entire dune systems in some cases along with destruction of fences and beach access walkways. The Lower Keys to the west of the eye, in the weak quadrant, sustained only minor beach erosion. Details by location can be found in the Post-Storm Report. Erosion and accretion are natural processes that are likely to continue to occur. The likelihood of significant instances of erosion will likely be tied to the occurrence of hurricane,tropical storm, and nor'easter events. Although NCEI only reports on erosion impacts from 4 events over the 25-year span between 1999 through 2024, DEP reports on an additional 7 events. In total,this equates to a 44 percent chance of erosion occurring every year. Additionally, drawing from the likelihood of hurricanes,tropical storms, and Nor'easters, erosion is likely to occur. Probability: 3—Likely As discussed under Climate Change in Section 4.5.5, climate change is expected to make heavy rain events and tropical storms and hurricanes more frequent and intense. As a result, the erosion typically caused by these storms can be expected to occur more frequently. Coastal erosion is also expected to increase as a result of rising seas. A 2018 study found that globally,between 1984 and 2015 erosion outweighed accretion. However,the study could not conclude the degree to which erosion during this period is attributed to climate changes or increased coastal development.Nonetheless, increases in erosion have been observed and are expected to continue.

Economic Condition of Beach re-nourishment projects to counter erosion are extremely costly. the Jurisdiction Water dependent industries may suffer from lost shoreline and degraded water quality. Public Confidence in the Erosion is unlikely to impact public confidence. Jurisdiction's Governance Natural hazards are often interconnected. Any given hazard may lead to, or be spurred by, another hazard —sometimes referred to as cascading disasters. Coastal erosion may be associated with tropical cyclones, coastal storms, storm surge, and flood. Increased development along the coastal areas vulnerable to erosion could speed up or intensify existing erosion processes. Enhanced development anywhere on the coast could create new erosional hotspots if not managed properly. U.S. Highway 1 is at risk where erosion is occurring along Sea Oats Beach. Erosion that impacts US Highway 1 could interrupt transportation on the entire Island Chain. As highlighted in Table 4.11,numerous recreational beaches and parks are at risk due to Coastal Erosion. Loss of such beaches would threaten the Keys' vital tourist economy. Mitigation strategies to address losses caused by coastal erosion should align with the Strategic Beach Management Plan for the Florida Keys Region. li �iii .d ai,4 IIL...o III iii t lii ii iii*.m Strategy J a iii`.m U a iii. .: .6 IIC:.)Eigei 65 SECTION 4: HAZARD IDENTIFICATION&RISK ASSESSMENT ui i Y Y uuuumll� oi �������miioi� im uumm uuuuu'uuu°m II uuuumuuuu The following table summarizes coastal erosion hazard risk by jurisdiction. Exposure to erosion varies slightly across jurisdictions,particularly in spatial extent. The ratings below are based on the length of miles of critically eroded beaches in each jurisdiction. The impact of erosion across jurisdictions is relatively similar—impacting public and private interests. Importantly, if erosion impacts transportation infrastructure it effects public and private interests the same. Layton is the only jurisdiction without a critically eroded shoreline, so it received impact and spatial extent ratings of 1; however, given the number of hurricanes and storms that impact the county,there is still a possibility that erosion might occur in Layton in the future,therefore it was rated as possible. Other jurisdictions received probability ratings based on prevalence of past and current erosion challenges.

It is a normal,recurrent feature of climate that occurs in virtually all climate zones. The duration of a drought varies widely. There are cases when drought develops relatively quickly and lasts a very short period, exacerbated by extreme heat and/or wind, and there are other cases when drought spans multiple years, or even decades. Studying the paleoclimate record is often helpful in identifying when long-lasting droughts have occurred. Common types of drought are detailed below in Table 4.13. IIIIIII assflllilll °itlili IIII11111li� Type Details Meteorological Drought Meteorological Drought is based on the degree of dryness (rainfall deficit) and the length of the dry period. Agricultural Drought Agricultural Drought is based on the impacts to agriculture by factors such as rainfall deficits,soil water deficits, reduced ground water,or reservoir levels needed for irrigation. Hydrological Drought Hydrological Drought is based on the impact of rainfall deficits on the water supply such as stream flow, reservoir and lake levels,and ground water table decline. Socioeconomic Socioeconomic drought is based on the impact of drought conditions Drought (meteorological,agricultural,or hydrological drought)on supply and demand of some economic goods.Socioeconomic drought occurs when the demand for an economic good exceeds supply as a result of a weather- related deficit in water supply. Source:National Drought Mitigation Center The wide variety of disciplines affected by drought, its diverse geographical and temporal distribution, and the many scales drought operates on make it difficult to develop both a definition to describe drought and an index to measure it. Many quantitative measures of drought have been developed in the United States, depending on the discipline affected,the region being considered, and the application. Several indices developed by Wayne Palmer, as well as the Standardized Precipitation Index, are useful for describing the many scales of drought. The U.S. Drought Monitor provides a summary of drought conditions across the United States and Puerto Rico. Often described as a blend of art and science,the Drought Monitor map is updated weekly by combining a variety of data-based drought indices and indicators and local expert input into a single composite drought indicator. The Palmer Drought Severity Index(PDSI) devised in 1965,was the first drought indicator to assess moisture status comprehensively. It uses temperature and precipitation data to calculate water supply and demand, incorporates soil moisture, and is considered most effective for unirrigated cropland. It primarily reflects long-term drought and has been used extensively to initiate drought relief. It is more complex than the Standardized Precipitation Index(SPI) and the Drought Monitor. li �iii .d ai,4 IIL...o III iii t lii ii iii*.m Strategy J a iii`.m U a iii. .: .6 IIC: SECTION 4: HAZARD IDENTIFICATION&RISK ASSESSMENT The Standardized Precipitation Index (SPI) is a way of measuring drought that is different from the Palmer Drought Severity Index(PDSI). Like the PDSI,this index is negative for drought, and positive for wet conditions. But the SPI is a probability index that considers only precipitation,while Palmer's indices are water balance indices that consider water supply(precipitation), demand(evapotranspiration) and loss (runoff). The State of Florida adopted a Drought Action Plan in 2007 that specifies response strategies to varying levels of declared drought. These rules provide the framework to coordinate statewide response to drought. Warning Time: I —More than 24 hours Duration: 4—More than one week Drought is a regional hazard that can impact large swaths of land—across county and even state lines. In the event of a drought, the entirety of Monroe County will experience impacts.

Figure 4.3 details the classifications used by the U.S. Drought Monitor. A category of D2 (severe) or higher on the U.S. Drought Monitor Scale can typically result in crop or pasture losses,water shortages, and the need to institute water restrictions. Drought in Florida occurs on a regular, cyclical basis. The different areas of Florida are randomly affected and sometimes equally affected. Counties that are expected to experience the most weeks of drought each year are the northern and central counties. Monroe County is susceptible to almost every level of drought on the U.S. Drought Monitor scale, however since 2000 it has not experienced and exceptional drought. The most severe period of drought since 2000 occurred in the spring of 2011 and reached extreme drought across 17% of Monroe County.

The following narratives were compiled from the Dashboard search results for Monroe County: — In November 2006, continuing drought conditions and related water supply concerns prompted the South Florida Water Management District to impose voluntary water use restrictions for residents and agriculture producers in Broward,Miami-Dade, Monroe, and Palm Beach Counties. Residents were asked to limit lawn irrigation and personal water use. — As a result of the ongoing drought in March 2007,the area received about half of the rainfall that they normally received leading to low water levels for Lake Okeechobee—the areas main backup water supply. Mandatory water restrictions were put into effect for the South Florida Water Management District. The restrictions are intended to reduce water consumption by 15%. Farmers were moved to Phase 2 to reduce consumption by 30%. — More than 30 Florida counties were declared to be natural disaster areas by the U.S. Department of Agriculture due to cold and drought between November 5 and December 17,2010. — In March 2018,the Florida Forest Service warned of a heightened wildfire risk statewide as drought conditions persisted. Extreme fire risk existed in Monroe,Miami-Dade, Broward,Lee, Martin,Indian River, Brevard, Highlands,Polk and Orange counties. The worst drought in Florida's recorded history was from 1954-1956 resulting in the loss of many of crops and a lot timber were lost. The Northern Counties got the worst part of the drought but most of the State was in drought for all of 1956. Another major drought occurred in 1981-1982 when rain was scarce, and Lake Okeechobee reached the lowest water level ever recorded. All the State was in moderate or severe drought,but many regions were out of drought by the end of 1981. Florida had another severe drought from 1998 to 2001. During this, crops were destroyed, lake levels were at an all-time low, and wildfires raged. This drought caused the water management districts to restrict water use,municipalities to hike water rates, and many restaurants were ordered to stop serving water except for to customers who asked. Several wildfires also occurred in 2007, including one in Monroe County,because of a drought from 2006 to 2007. This period saw the largest rainfall deficit since the 1950s and was considered a one in 25-year drought event. From 2010 to 2012, the State saw a drought that affected most counties,but the northern central and Panhandle regions were classified as in"extreme drought"for an extended period. Again in 2016, drought conditions developed and lasted into 2017 causing many wildfires. �A('Irvrc)e courity, fllscfi�cda,4 IIL...o III itigatii'a r'i Strategy Jw"W&''y 2(`)26 SECTION 4: HAZARD IDENTIFICATION&RISK ASSESSMENT There has never been a Presidential Major Disaster Declaration for drought in Florida. However, the USDA has declared agricultural disasters because of drought. Disaster designations help producers get loans and emergency assistance in these situations. 4.0 Based on historical occurrences,the probability that the County will experience some level of drought is likely,with Monroe County in drought 42 percent of the time during the period from 2000 through 2024. Over the same time period, approximately 133 weeks were categorized as a severe (D2) drought or greater; which equates to a 10 percent chance of severe drought in any given week. Probability: 3—Likely The Fourth National Climate Assessment reports that average and extreme temperatures are increasing across the country and average annual precipitation is decreasing in the Southeast. Heavy precipitation events are becoming more frequent,meaning that there will likely be an increase in the average number of consecutive dry days. As temperature is projected to continue rising, evaporation rates are expected to increase,resulting in decreased surface soil moisture levels. Together, these factors suggest that drought will increase in intensity and duration in the Southeast. The Fifth National Climate Assessment upholds the climate trends reported in the Fourth Assessment and presents additional patterns in the Southeast that exacerbate climate risk and impacts. These patterns include population growth,high proportion of the population with health issues or underlying health conditions, and a large, climate-dependent agricultural sector.'

PEOPLE Drought can affect people's physical and mental health. For those economically dependent on a reliable water supply, drought may cause anxiety or depression about economic losses,reduced incomes, and other employment impacts. Conflicts may arise over water shortages. People may be forced to pay more for water, food, and utilities affected by increased water costs. Drought may also cause health problems due to poorer water quality from lower water levels. If accompanied by extreme heat, drought can also result in higher incidents of heat stroke and even loss of human life. The Florida Keys experience dry and wet seasons and are sometimes characterized by an and climate. As the County is supplied by water from the mainland,residents always need to be aware of preserving water,but especially during drought periods. The Florida Key's Aqueduct Authority and the South Florida Water Management District will issue restrictions as needed. Such restrictions are predominantly intended for lawn and vegetation maintenance,but irresponsible water use will affect residents' access to water with continued development. .......................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................

ENVIA10NMENT Drought can affect local wildlife by shrinking food supplies and damaging habitats. Sometimes this damage is only temporary, and other times it is irreversible. Wildlife may face increased disease rates due to limited access to food and water. Increased stress on endangered species could cause extinction. Residents are aware of the need to use native vegetation and ground cover to avoid the need for excessive watering. Drought conditions can also provide a substantial increase in wildfire risk. As plants and trees die from a lack of precipitation,increased insect infestations, and diseases all of which are associated with drought they become fuel for wildfire. Long periods of drought can result in more intense wildfires, which bring additional consequences for the economy,the environment, and society. Drought may also increase likelihood of wind and water erosion of soils. .......................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................

Any given hazard may lead to, or be spurred by, another hazard —sometimes referred to as cascading disasters. Drought may be associated with wildfire and extreme heat. Drought is predominantly controlled by larger weather patterns and less by human development. However, increased development and the resulting increasing impervious surfaces would mean less surface water would be able to directly infiltrate into the ground. Further,because the County's water is predominantly supplied by the Biscayne aquifer in Miami-Dade County,new development and population growth in Monroe County as well as Miami-Dade and other areas supplied by the aquifer will increase water demand. In turn,this could lower the threshold for socioeconomic drought in terms of an inability of water supply to mee water demand. Drought is a regional hazard. If drought impacts Monroe County, it will similarly be impacting neighboring counties and towns. The Keys get most of their drinking water from the Biscayne Aquifer and supplement with water from the Floridan Aquifer. In the case of a drought,water supply could be impacted. Water is already transported long distances to reach the keys, and in drought circumstances the distance water must travel could increase. Drought can create or exacerbate water quality issues. Though the Biscayne Aquifer is of superior quality, the Floridan Aquifer is considered brackish and experience saltwater intrusion. The following table summarizes drought hazard risk by jurisdiction. Drought risk is uniform across the planning area. Warning time, duration, and spatial extent are inherent to the hazard and remain constant across jurisdictions. Drought most commonly and severely impacts agricultural activities, of which there are few in the County. In more heavily developed areas,the magnitude of drought is less severe,with lawns and local gardens affected and potential impacts on already constrained local water supplies during severe,prolonged drought.

X111TREME HEAT Hazard Probability Impact Spatial Warning Time Duration PRI Extent Score Extreme Heat Likely Limited Large More than 24 More than 1 '7 hrs week Per information provided by Ready.gov, in most of the United States extreme heat is defined as a long period(2 to 3 days) of high heat and humidity with temperatures above 90 degrees. As temperatures rise, our bodies naturally cool down by sweating. In extreme heat,the body must work extra hard to maintain a normal temperature and sweating might not be enough to cool down. When this happens, a person's body temperature rises faster than it can cool itself. Additionally,when the humidity is high, as is common during extreme heat events in North Carolina, evaporative cooling through sweating becomes less effective. Heat-related illnesses occur when the body overheats from exposure to high temperatures and in severe cases can cause damage to the brain and other vital organs. Heat-related illnesses can also arise from moderate to vigorous physical activity in hot situations. Extreme heat often results in the highest annual number of deaths among all weather-related disasters. On average,the number of extreme heat days has been increasing each year,putting residents at a higher risk of heat-related illnesses. In 2023,more people in the United States died of heat-related illness than any year on record. Per Ready.gov, older adults, children, and people with certain illnesses and chronic conditions are at greater risk from extreme heat; and humidity increases the feeling of heat. The National Weather Service(NWS)uses the heat index, also known as apparent temperature,to determine when to issue health alerts. The heat index is a measure of how hot it really feels when the relative humidity is considered along with the actual air temperature. In most areas of the country,the NWS generally issues alerts "when the heat index is expected to exceed 105T -I IOT for at least two consecutive days,"but they also work with local partners to determine the most appropriate conditions for a specific geography. Ambient air temperature is one component of heat conditions,with relative humidity being the other. The relationship of these factors creates what is known as the apparent temperature. The Heat Index Chart in Figure 4.5 uses both factors to produce a guide for the apparent temperature or relative intensity of heat conditions. li �iii .d ai,4 IIL...o III iii t lii ii iii*.m Strategy J a iii`.m U a iii. .: .6 IIC:.)Eigei 1741 SECTION 4: HAZARD IDENTIFICATION&RISK ASSESSMENT IIIIIII""""""IIIIIII ""e 11114, °t IIIIIII IIIIide IIIIIII P"''IIIIIIP' NWS Heat, ICI l Tempe,rature, (QF1) F 80 82 84 8,6 88 90 92 94 96, 2 104 106 108 110, r „ Di a vi, .. ,i9 M ', V u 11 83 85 �. a f �rQVl�� i 01 �u u ev 66, Bs V I vi, > 75r. ui', Wu WIWffWirf... 3. :V I vi it u pi b«r iu 9 r `v Li e4 o— ea Dis `s,"nth Protonged Expossure or'Strenuous Activity ED Caut ionr�xIe CajtlIlII EM ria r1gelr EXtren ile Diai,17ger� Source:National Weather Service(NWS)https://www.weather.gov/safety/heat-index Note:Exposure to direct sun can increase Heat Index values by as much as 15°F.The shaded zone above 105°F corresponds to a heat index that may cause increasingly severe heat disorders with continued exposure and/or physical activity. During these conditions,the human body has difficulties cooling through the normal method of the evaporation of perspiration. Health risks rise when a person is overexposed to heat. The most dangerous place to be during an extreme heat incident is in a permanent home,with little or no air conditioning. Those at greatest risk for heat-related illness include people 65 years of age and older,young children, people with chronic health problems such as heart disease,people who are obese,people who are socially isolated, and people who are on certain medications, such as tranquilizers, antidepressants, sleeping pills, or drugs for Parkinson's disease. However, even young and healthy individuals are susceptible if they participate in strenuous physical activities during hot weather or are not acclimated to hot weather.

A heat advisory is issued when temperatures reach 105°F and a warning is issued at 115°F. Impacts of extreme heat are not only focused on human health, as prolonged heat exposure can have devastating impacts on infrastructure as well. Prolonged high heat exposure increases the risk of pavement deterioration, as well as railroad warping or buckling. High heat also puts a strain on energy systems and consumption, as air conditioners are run at a higher rate and for longer; extreme heat can also reduce transmission capacity over electric systems. Warning Time: I —More than 24 hours Duration: 3—Less than one week Monroe County and its jurisdictions are susceptible to high temperatures and incidents of extreme heat. Spatial Extent: 4—Large The extent of extreme heat can be defined by the maximum apparent temperature reached. Apparent temperature is a function of ambient air temperature and relative humidity and is reported as the heat index. The NWS Southern Region sets the following criteria for heat advisory and excessive heat warning: — Heat Advisory—Heat Index of 108°F or higher or temperature of 103°F or higher — Excessive Heat Warning—Heat Index of I I YF or higher for any duration or temperature of 103°F or higher Table 4.16 notes the highest temperature on record at nine weather stations in Monroe County according to the Southeast Regional Climate Center,which maintains temperature records for the highest maximum temperature each month. uum uum IIIIIII IIIIIII uu""'IIIIIII ii w uuuuuuuu uumm IIIIIII m m uum uuuu o uu IIIIIII V IIIIIII m n III,ouuuu.IIIIIII uuuum �� IIIIIII IIIIIII Temperature Location Date 101OF Dry Tortugas August 1992 960F Key West I nt'I Airport August 2024* 100OF Bahia Honda State Park July 2023 970F Curry Hammock State Park July 2011* 990F Duck Key July 1987 930F Islamorada August 2010 980F Tavernier September 1963 95OF John Pennekamp State Park July 2018 970F Flamingo Ranger Station September 2013 Source: Southeast Regional Climate Center;only for stations with records within the past 20 years. *Some maximum temperatures were recorded more than once,where this occurred,the most recent occurrence is noted.

Per the Fifth National Climate Assessment, "The number of extreme warm days (above 95°F) is expected to continue increasing with every increment of global warming"and that"heatwaves in the Southeast are happening more frequently and are occurring during a longer heat season, with some cities also showing increasing trends in their duration and intensity."Additional heat stresses can be attributed to the urban heat island effect which can increase the temperature of those living in urban environments compared to rural areas. The number of days over 95°F is expected to increase by between 10 and 40 days annually within the Everglades area of Monroe County as shown in Figure 4.6. Data is unavailable for the Florida Keys.

Any given hazard may lead to, or be spurred by, another hazard —sometimes referred to as cascading disasters. Extreme heat may be associated with drought and wildfire. More intensive development can increase the urban heat island effect—where the concentration of structures, infrastructure, and human activity traps and stores heat resulting in localized"heat islands." Information is not available on the extent to which impervious surface coverage has changed since the adoption of the previous hazard mitigation plan. Populations most vulnerable to the effects of excessive heat are children under the age of 5 and those over the age of 65. Key Colony Beach and Layton have more than a third of their population in the 65 and above category. Key west has over 5% of its population in the under 5 category. The county and participating jurisdictions may want to consider identifying community spaces that can serve as cooling centers and publicize those spaces in advance of forecasted extreme heat. The following table summarizes extreme heat hazard risk by jurisdiction. Extreme heat risk does not vary significantly by jurisdiction.

As defined by FEMA, a flood is a general and temporary condition of partial or complete inundation of two or more acres of normally dry land area or of two or more properties. Flooding can result from an overflow of inland waters or an unusual accumulation or runoff of surface waters from any source. Flooding causes more damage in the United States than any other severe weather related event, an average of$5 billion a year. Approximately 90 percent of presidentially declared disasters result from flood-related natural hazard events. Taken as a whole,more frequent, localized flooding problems that do not meet federal disaster declaration thresholds ultimately cause the majority of damages across the United States. ....................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................... SOURCES L D Per the 2005 Flood Insurance Study(FIS), flooding results mainly from storm surge flooding in the areas of the county bordering the Atlantic Ocean and Gulf of Mexico when tidal surges,wave action, and heavy rainfall combine. The general topography of Monroe County is extremely flat,with natural elevations of 4 to 7 feet above mean sea level. Shallow slopes and the generally low-lying nature of the keys makes the County vulnerable to flooding during coastal events and heavy rains. Some rainfall in the area runs off into the surrounding seas and other rainfall that is caught in closed basins can drain relatively quickly into underlying coral rock and limestone soils that have high infiltration rates. However, there are still instances of rainfall flooding that does not runoff or drain quickly, causing water to accumulate in ponded areas. Additionally, there are approximately 170 miles of canals in the Florida Keys. Mismanagement and improper cleaning of these canals also causes flooding from heavy rains,hurricanes, and tidal systems. Coastal Tidal Flooding: All lands bordering the Atlantic and Gulf Coasts are susceptible to tidal effects and flooding. Coastal land such as sand bars,barrier islands and deltas provide a buffer zone to help protect human life and real property relative to the sea much as flood plains provide a buffer zone along rivers and other bodies of water. Coastal floods usually occur because of abnormally high tides or tidal waves, storm surge and heavy rains in combination with high tides,tropical storms and hurricanes. Shallow Ponding: Because much of the County is flat,whatever rainfall doesn't flow from an area tends to pond and percolate into the ground, causing water tables to rise during the wet season and periods of extended rainfall and reducing the capacity for soil storage and infiltration. Flash or Rapid Flooding: A flash flood occurs when water levels rise at an extremely fast rate as a result of intense rainfall over a brief period,possibly from slow-moving intense thunderstorms and sometimes combined with saturated soil, or impermeable surfaces. Flash flooding can happen in Special Flood Hazard Areas (SFHAs) as delineated by the National Flood Insurance Program(NFIP) and can also happen in areas not associated with floodplains. Flash flood hazards caused by surface water runoff are most common in urbanized areas,where greater population density generally equates to more impervious surface(e.g.,pavement and buildings)which increases the amount of surface water generated. li �iii .d ai,4 IIL...o III iii t lii ii iii*.m Strategy wi"m �&i. .: .6 IIC:�)Eigei P�..111 SECTION 4: HAZARD IDENTIFICATION&RISK ASSESSMENT Flash flooding is a dangerous form of flooding which can reach full peak in only a few minutes. Rapid onset allows little or no time for protective measures. Flash flood waters move at very fast speeds and can move boulders, tear out trees, scour channels, destroy buildings, and obliterate bridges. Flash flooding can result in higher loss of life,both human and animal,than slower developing river and stream flooding. Localized/Stormwater Flooding: Localized stormwater flooding can occur in Monroe County. Localized stormwater flooding occurs when heavy rainfall and an accumulation of runoff overburden the stormwater drainage system. The cause of localized stormwater flooding in Monroe County can be attributed to its generally flat topography, among other factors. Localized flooding may be caused by the following issues: — Inadequate Capacity—An undersized/under capacity pipe system can cause water to back-up behind a structure which can lead to areas of ponded water and/or overtopping of banks. — Clogged Inlets—Debris covering the asphalt apron and the top of grate at catch basin inlets may contribute to an inadequate flow of stormwater into the system. Debris within the basin itself may also reduce the efficiency of the system by reducing the carrying capacity. — Blocked Drainage Outfalls—Debris blockage or structural damage at drainage outfalls may prevent the system from discharging runoff,which may lead to a back-up of stormwater within the system. — Improper Grade—Poorly graded asphalt around catch basin inlets may prevent stormwater from entering the catch basin as designed. Areas of settled asphalt may create low spots within the roadway that allow for areas of ponded water. While localized flooding may not be as destructive as coastal flooding, it is a chronic problem. The repetitive damage caused by such flooding can add up. Sewers may back up,yards can be inundated, and homes,businesses and vehicles can be flooded. Drainage and sewer systems not designed to carry the capacity currently needed to handle increased storm runoff can cause water to back into basements and damage mechanical systems. These impacts, and other localized flooding impacts, can create public health and safety concerns. In addition to these different types of flooding, flooding in Monroe County is a factor of the amount and timing of rainfall and the tide cycle elevation. The amount of rainfall occurring in March would not have the same flooding effect if the same amount occurred in September. During the dry season,the water table elevation typically drops to several feet below natural ground elevations. This allows for larger storage volume in the soil, lakes, canals, ditches, and swales. During the wet season,however, the water table elevation is often near the natural ground surface, lakes are filled, and ditches are flowing. The rainfall added to such conditions creates more stormwater runoff. ....................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................... A floodplain, as shown in Figure 4.7 and Figure 4.8, is flat or nearly flat land adjacent to a stream,river, or body of water that experiences occasional or periodic flooding. In riverine floodplains, it includes the floodway, which consists of the stream channel and adjacent areas that carry flood flows, and the flood fringe,which are areas covered by the flood,but which do not experience a strong current. Floodplains are made when floodwaters exceed the capacity of the main channel or escape the channel by eroding its banks. When this occurs, sediments(including rocks and debris) are deposited that gradually build up over time to create the floor of the floodplain. Floodplains generally contain unconsolidated sediments, often extending below the bed of the stream. In coastal floodplains, zones are distinguished by wave heights. Floodplain boundaries are designated and routinely updated through cooperation between local governments, states and the FEMA.

The 500-year flood is the flood that has a 0.2 percent chance of being equaled or exceeded in any given year. The potential for flooding can change and increase through various land use changes and changes to land surface,which result in a change to the floodplain. A change in environment can create localized flooding problems inside and outside of natural floodplains by altering or confining natural drainage channels. These changes are most often created by human activity. The 1-percent-annual-chance flood,which is the minimum standard used by most federal and state agencies, is used by the National Flood Insurance Program(NFIP) as the standard for floodplain management and to determine the need for flood insurance. Participation in the NFIP requires adoption and enforcement of a local floodplain management ordinance which is intended to prevent unsafe development in the floodplain,thereby reducing future flood damages. Participation in the NFIP allows for the federal government to make flood insurance available within the community as a financial protection against flood losses. Since floods have an annual probability of occurrence, have a known magnitude, depth and velocity for each event, and in most cases,have a map indicating where they will likely occur, they are in many ways often the most predictable and manageable hazard. Warning Time: 3— 6 to 12 hours Duration: 3—Less than I week Regulated floodplains are illustrated on FIRMs,which are the official maps for a community on which FEMA has delineated both the Special Flood Hazard Areas (SFHAs) and the risk premium zones applicable to the community. SFHAs represent the areas subject to inundation by the 1-percent-annual- chance flood event. Table 4.19 summarizes the flood insurance zones identified by the Digital FIRMs (DFIRMs). 4.19 reflects the effective mapped flood insurance zones for Monroe County and Figure 4.10 shows the mapped preliminary DFIRM. Maps for each participating jurisdiction are provided in the jurisdictional annexes. Flooding can occur anywhere in Monroe County.

AE Zones,also within the 100-year flood limits,are defined with BFEs that reflect the combined influence of stillwater flood elevations and wave effects less than 3 feet.The AE Zone generally extends from the landward VE zone limit to the limits of the 100-year flood from coastal sources,or until it reaches the confluence with riverine flood sources. AE The AE Zones also depict the SFHA due to riverine flood sources, but instead of being subdivided into separate zones of differing BFEs with possible wave effects added,they represent the flood profile determined by hydrologic and hydraulic investigations and have no wave effects.The Coastal AE Zone is differentiated from the AE Zone by the Limit of Moderate Wave Action (LiMWA) and includes areas susceptible to wave action between 1.5 to 3 feet.

AREAS LIKELY TO FLOOD IN THE FU I I JRE Based on this assessment of the locations vulnerable to current flooding and potential changes to flood conditions discussed under the Climate Change and Changes in Development sections below, the following locations were identified as areas that are likely to flood in the future: — Special Flood Hazard Areas and 0.2% annual-chance floodplains: According to both the effective and preliminary FIRMs, about 94 percent of Monroe County is located within the SFHA, and between 0.1 and 0.2 percent of the county is located within the 0.2%annual-chance floodplain. These areas are at high risk of future flooding. While new development and redevelopment is limited, changes in floodplain development and future development within the watershed in general as well as climate change-driven changes in rainfall probabilities and intensities could increase the size of the SFHAs and/or the depth of flooding in these areas in the future. — Localized stormwater flooding areas: It is highly likely that areas without stormwater drainage infrastructure or with undersized or underperforming drainage infrastructure will continue to experience localized flooding problems. Specific problem locations are listed above. Areas with vacant land that may be developed and converted into impervious surface area may be more likely to flood in the future if steps are not taken to mitigate the impacts of development. — Repetitive loss areas: Many repetitive losses can be attributed to coastal flooding and storm surge events which may become more severe due to sea level rise. Therefore, it is very likely that unmitigated repetitive loss properties will continue to flood in the future. Repetitive loss counts are detailed later in this section and areas vulnerable to storm surge are detailed in Section 4.5.7. — Areas vulnerable to sea level rise: Sea level rise will increase vulnerability to high tide flooding and coastal flooding and can even increase stormwater flooding if drainage outfalls are impeded by higher water levels. Areas directly vulnerable to sea level rise are detailed in Section 4.5.5. These areas are likely to flood in the future. III �i �i .��i � � I i�lLi'i i*.m Strategy y wi"m �&i. .: .6 IIC:.)Eige 88 SECTION 4: HAZARD IDENTIFICATION&RISK ASSESSMENT Flood extent can be defined by the amount of land in the floodplain and the potential magnitude of flooding as measured by flood height and velocity. FEMA Flood Insurance Studies define the probability of flooding by flood events of a magnitude which are expected to be equaled or exceeded once on the average during a specific time period, or recurrence interval. Per this assessment, approximately 99 percent of Monroe County falls within the SFHA, an additional 5.2 percent of the County area is open water. Therefore, effectively 99 percent of the county's land area (not classified as open water) is within the SFHA. Table 4.20 provides a summary of the County's total area by flood zone on the 2005 effective DFIRM and a comparison to flood zone acreage on the preliminary DFIRM(released in December 2019). Changes from the effective DFIRM include over 62,000 acres of land no longer in the AE zone, over 44,000 acres now classified in the A zone,which was previously not included in the County's flood maps, and over 18,000 acres now classified as VE. Additionally, the preliminary maps represent an 79%increase in acreage in the 0.2% annual chance flood zone. Figure 4.11 shows the depth of flooding predicted from a I% annual chance flood.

Floods of other magnitudes may occur. The remainder of the planning areas is subject to moderate and low flood risk. Low risk is not no risk; areas outside the SFHA may still be flooded by heavy rain events and/or more severe coastal floods.

Several thunderstorm cells tracked northeast across Duck Key and Long Key,producing very heavy rainfall and minor flooding.A Long Key State Park, 5.38 inches of rain were observed in two hours,with a final storm total rainfall of 9 inches. State Park Rangers reported 6 campsites were washed out and a park road was flooded. There were also reports of a flooded parking lot at the Layton Post Office. 5.6 inches of rain were reported in Duck Key. August 18,2008—Tropical Storm Fay moved through the Lower Florida Keys during the evening of August 18, 2008,producing tropical storm force winds and heavy rainfall. Rainfall produced widespread street flooding in Key West. This flooding caused a small section of the tarmac at the Key West international airport to collapse. In total,rainfall amount of 3.5 to 4.0 inches were reported in the Key West area,up to 7.27 inches in Marathon, and 7.05 inches in Ramrod Key,resulting in temporary street and low area flooding. September 29,2010- Thunderstorms focused along a convergence zone indirectly related to Tropical Storm Nicole produced heavy rainfall and extensive street flooding over Lower and Upper Matecumbe Keys within the Village of Islamorada. Water entered one home on Lower Matecumbe Key, causing one family to be temporarily displaced. October 17,2011—Persistent showers and thunderstorms moved across the extreme Lower Florida Keys due to lower pressure over the Yucatan Peninsula. Street flooding of 3 to 4 feet deep was reported at the corners of White and Eaton Streets and Caroline and Margaret Streets in Old Town Key West, as well as at Donald and 20th Streets in New Town Key West. Several cars were stranded due to street flooding along South Roosevelt Boulevard between the Overseas Highway and Flagler Avenue, as well as near 1 st Street and North Roosevelt Boulevard. Isolated low elevation home flooding was observed in Mid Town Key West along Fogarty Avenue. October 19,2011 -A low pressure system in the eastern Gulf of Mexico assisted in the formation of three separate squall lines,which moved east through the Florida Keys and surrounding coastal waters from the evening of October 18th through morning of October 19th. Widespread gale-force wind gusts li �iii .d ai,4 IIL...o III iii t lii ii iii*.m Strategy wi"m �&i. .: .6 IIC:.)Eige 92 SECTION 4: HAZARD IDENTIFICATION&RISK ASSESSMENT and street flooding occurred across the Lower and Middle Florida Keys, along with a damaging waterspout across the Anchorage at Key West Harbor. Flooding was observed at Sigsbee Park at Dredgers Key in Key West, as well as up to three feet deep at the Stadium Apartments in New Town Key West. Flooding of side streets up to two feet was observed in Marathon. May 2,2013—Thunderstorms developed in cyclic fashion over Key West and adjacent nearshore waters over a duration of three hours,producing widespread street flooding and flooding to businesses along the lower elevations of Key West. Flooding was reported in the Old Town Historic District of Key West, including up to two feet of flood depth at the corner of Front and Simonton Streets, at Duval and Greene Streets, and at the corner of White and Eaton Streets and up to three feet in depth at Duval and Front Streets. Up to 7 inches of rain was measured at the Key West Wastewater Treatment Plant on the south end of Fleming Key. Several businesses had water inundation to around 6 inches in depth. Significant flooding was observed on Patterson Street in Mid-Town Key West, causing a commercial-sized dumpster to float down the street. Further flooding included inundation of two and a half feet along Thompson and George Streets, and up to one foot in depth at the corner of Jose Marti Drive and North Roosevelt Boulevard. A retention and floodwater staging pond overflowed due to blocked drainage culverts leading to the Gulf of Mexico under North Roosevelt Boulevard. Street flooding up to two feet in depth was also observed along South Roosevelt Boulevard between Flagler Avenue and the Overseas Highway. September 21,2015-Minor coastal flooding occurred in a few Florida Bayside neighborhoods in North Key Largo, due mostly to persistent large northeast fetch occurring offshore the southeast U.S. Coast. Due to the very small diurnal tidal range of 2 to 3 inches in the far eastern end of Florida Bay and Blackwater Sound. Continuous coastal flooding of streets began approximately 17:00 EST on September 21 st in the area of Adams and Shaw Drive in North Key Largo's bayside, gradually expanding to adjacent streets throughout the Blackwater Sound and Sexton Cove shorelines. While no homes or businesses were flooded,the depth of water reached as high as 0.8 feet by September 30th,with a couple streets becoming impassable to small vehicles. The flooding was confirmed by Monroe County Emergency Management and Key Largo Fire Rescue. October 5,2017-Abnormally high spring tides occurred throughout the Florida Keys as result of seasonal autumn King Tides and prolonged strong northeast to east winds. Coastal Flooding with saltwater depth 3 to 6 inches above street level observed at the corner of Truman Avenue and North Roosevelt Boulevard in Key West. U.S. Coast Guard and National Weather Service personnel confirmed further coastal flooding in the Upper Florida Keys,with saltwater depth 6 to 8 inches above streets on the oceanside of Rock Harbor, and minor flooding of the U.S. Highway 1 northbound lane at Sea Oats Beach, Lower Matecumbe Key, near Mile Marker 74.5. Coastal Flooding was also confirmed along West Ocean Drive in Key Colony Beach,with saltwater depth 6 inches over the road. Coastal flooding of near 1 foot in depth was observed near Sombrero Beach in Marathon. December 12,2018—A strong extratropical cyclone moving northeast over the Gulf of Mexico pushed a cold front through the Florida Keys. Strong west winds overspread the Florida Keys and Florida Bay, causing water levels to rise quickly. Water levels along several Florida Bay neighborhoods from near Mile Marker 100 through 106 off the Overseas Highway reported flooding of yards, docks, and streets generally from 6 to 18 inches in depth. Several ground-floor slab homes had flooding of attached porches, with water levels nearly entering the homes. May 10,2020—Thunderstorms developed in the early morning hours just north of a stationary front extending west-to-east across the Straits of Florida. Heavy rainfall produced widespread flooding on Long Key including the City of Layton. Secondary roads and parking lots were flooded through most portions of the City of Layton. Rainfall more than 4 inches was estimated by radar. June 4,2022—Rainfall from the early morning hours of June 3rd through the afternoon of June 4th totaled generally 6 to 11 inches in the upper Florida Keys, from 5.5 to 8.5 inches in the middle Florida li �iii .d ai,4 IIL...o III iii t lii ii iii*.m Strategy wi"m �&i. .: .6 IIC:.)Eige 93 SECTION 4: HAZARD IDENTIFICATION&RISK ASSESSMENT Keys, and 3 to 6 inches in the lower Florida Keys. Isolated flood damages occurred in the upper Florida Keys where rainfall was heaviest. Localized street flooding was observed in several neighborhoods in the Key Largo through Tavernier areas of the upper Florida Keys. In addition, a few boats on lifts with drain plugs left in were damaged or dropped into local canals due to the weight of accumulated rainfall onboard. November 15,2023— Strong low pressure over the eastern Gulf of Mexico resulted in a slow-moving pre-frontal trough focusing heavy convective rainfall over portions of the middle and upper Florida Keys. Heavy rainfall estimated by radar of 5 to 8 inches produced extensive poor drainage area flooding across Marathon and Key Colony Beach,with some streets with one to two feet depth of water. Several motor vehicles stalled due to flooding. December 17,2023—Bands of showers moved across the region on the 16th and early on the 17th, producing wind gusts up to 50-60 mph over the waters. Due to the prolonged period of gusty gradient winds and convective gusts, it led to a spike in high tides,which created coastal flooding in Palm Beach and Flamingo during the local high tides. The National Park Service reported coastal flooding that inundated the campgrounds,housing area, and maintenance areas around Flamingo. Eleven vehicles had water intrusion, and one required a tow truck. Four trailer pads closest to the shoreline had the concession resident trailers damaged, including one RV with heavy damage. August 20,2024—Higher than normal water levels occurred in late August due to the full moon cycle, or king tides, across the Gulf coast of South Florida. Minor coastal flooding was possible during high tide with the peak height. An Everglades National Park ranger reported minor saltwater flooding in Flamingo, on the flood-prone campground ad j acent to the water, during the high tide cycles. Standing water was less than one foot on the road at the Flamingo Campground. The Monroe County LMSWG also noted the importance of the following event: November 11-12, 1980: The"Veteran's Day Storm"resulted from the influence of a stalled cold front and Tropical Storm Jeanne that was over Cuba. In total,these combined systems produced 23 inches of rain in 24 hours. Even though much of the water was running off into the surrounding seas,the event resulted in widespread flooding especially in streets and low-lying areas. Weather Service reports indicated that 300 vehicles and 500 buildings were seriously damaged, resulting in$1 million in property damage,primarily in Key West. By definition the SFHAs are defined as those areas that will be inundated by the flood event having a 1- percent chance of being equaled or exceeded in any given year. Properties located in these areas have a 26 percent chance of flooding over the life of a 30-year mortgage. The shaded X Zone indicates areas that are estimated to be inundated by the flood event having a 0.2-percent chance of being equaled or exceeded in any given year. The SFHA and the Shaded X Zone indicate areas of high and moderate risk according to FEMA guidelines; however,this does not mean that flood risk is limited to these areas. There is also potential for other magnitudes of flood events to impact these and other areas in the region. While exposure to flood hazards vary across jurisdictions, all jurisdictions have high risk flood hazard areas, and the entire county faces some level of flood risk. Additionally,there is risk of localized and stormwater flooding as well as severe wind-driven surge in areas outside the SFHA. Based on these considerations as well as the 49 flood-related events recorded by NCEI over the last 24 years,the probability of flooding is considered highly likely(100% annual probability) for all jurisdictions. Probability: 4—Highly Likely li �iii .d ai,4 IIL...o III iii t lii ii iii*.m Strategy wi"m �&i. .: .6 IIC:.)Eige g ui. SECTION 4: HAZARD IDENTIFICATION&RISK ASSESSMENT The potential for flooding can change and increase. Various land use changes and changes to land surface can result in changes to the floodplain and flood prone areas. For example, an increase in impervious surface can create localized flooding problems inside and outside of natural floodplains by altering or confining natural drainage channels. These changes are often created by human activity. However, changes in precipitation frequency and intensity can also result in changes to flood magnitudes and probabilities. For example,what we currently define as the 1-percent-annual-chance flood may occur more frequently in the future. Per the Fourth National Climate Assessment, frequency and intensity of heavy precipitation events is expected to increase across the country. More specifically, it is"very likely"(90-100%probability)that most areas of the United States will exhibit an increase of at least 5% in the maximum 5-day precipitation by late 21 st century. Additionally, increases in precipitation totals are expected in the Southeast. Climate change will increase people's exposure to coastal flooding and likely cause an increase in inland flooding in the Monroe County region. Higher ocean temperatures will lead to more intense storms. As temperatures increase so does evaporation,producing greater rainfall intensity. A warmer atmosphere can hold more moisture,which can result in heavier, longer-lasting rainfall events. The increase in rainfall means effects of a storm can be felt miles away and far inland. Additionally,the speed at which tropical cyclones move, is expected to slow,meaning longer periods of storm-related rainfall will occur potentially causing disastrous inland flooding. As the intensity of coastal storms increase, coastal communities may experience higher levels of surge and more intense impacts from flooding. Surge depths will be higher as sea levels rise, expanding the boundary of coastal flood areas and impacting more communities along the coast.

E HODOLOGIES AND ASSUMPTIONS WSP conducted a Level 2 Hazus Flood Simulation by leveraging the 1%-annual-chance flood boundaries from the effective FEMA Flood Insurance Study dated 02/18/2005. Base Flood Elevations were converted to a depth raster using LiDAR topography obtained from USGS. WSP also leveraged the 2024 parcel data provided by Monroe County and building footprints for the loss determination. Parcels that were potentially at risk of flooding from the 1%-annual-chance flood zone were selected for analysis. Only areas that were contained within the extent of available LiDAR, and by extension the depth grid, were analyzed. This accounted for 99.9% of all structures in the SFHA. Losses were derived in Hazus using USAGE depth damage functions, shown in Table 4.23. Flood damage is directly related to the depth of flooding by the application of a depth damage curve. In applying the curve, a specific depth of water translates to a specific percentage of damage to the structure, which translates to the same percentage of the structure's replacement value. Figure 4.11 depicts the depth of flooding that can be expected within the Monroe County planning area during the 1%-annual- chance flood event. °° IIIIIII IIIIIII IIIIIII IIIIIII ������������1111���������������°����� Percent Damaged(%) Depth ( Agricultural Commercial Education Government Industrial Religious Residential 0 0 1 0 0 1 0 18 1 6 9 5 5 10 10 22 2 11 14 7 8 12 11 25 li �iii .d ai,4 IIL...o III iii t lii ii iii*.m Strategy J a iii`.m U a iii. .: .6 SECTION 4: HAZARD IDENTIFICATION&RISK ASSESSMENT Percent Damaged(%) Depth ( Agricultural Commercial Education Government Industrial Religious Residential 3 15 16 9 13 15 11 28 4 19 18 9 14 19 12 30 5 25 20 10 14 22 12 31 6 30 23 11 15 26 13 40 7 35 26 13 17 30 14 43 8 41 30 15 19 35 14 43 9 46 34 17 22 29 15 45 10 51 38 20 26 42 17 46 11 57 42 24 31 48 19 47 12 63 47 28 37 50 24 47 13 70 51 33 44 51 30 49 14 75 55 39 51 53 38 50 15 79 58 45 59 54 45 50 16 82 61 52 65 55 52 50 17 84 64 59 70 55 58 51 18 87 67 64 74 56 64 51 19 89 69 69 79 56 69 52 20 90 71 74 83 57 74 52 21 92 74 79 87 57 78 53 22 93 76 84 91 57 82 53 23 95 78 89 95 58 85 54 24 96 80 94 98 58 88 54 Source:Hazus Building foundation types were not available in the parcel or building data provided by Monroe County but are required for Hazus. Therefore,based on local knowledge and experience,WSP made the assumption that 40%of the foundations in Monroe County are elevated, 25% are crawl space, and 35% are slab on grade. Loss numbers are based on improved parcel values listed in the 2024 parcel data from Monroe County. Parcels with values greater than or equal to $5,000 are considered improved parcels. Parcels with building values less than$5,000 but with building footprint of single structure greater than 600sgft within boundary are considered improved parcels. All parcels with building values less than$5,000 and no building footprint or no single building footprint greater than 600sgft are considered unimproved parcels. Content value estimations are based on Hazus methodologies of estimating value as a percent of improved structure values by property type.

PEOPLE Flood events pose many threats to public health and safety. While such problems are often not reported, three general types of health hazards accompany floods: physical hazards from the water itself, environmental hazards in the aftermath of the flood, and long-term psychological hazards. These common health and safety hazards are detailed below: — Contaminated water: Floodwaters carry anything that was on the ground that the upstream runoff picked up, including dirt, oil, animal waste, and lawn, farm and industrial chemicals. Pastures and areas where farm animals are kept or where their wastes are stored can contribute polluted waters to the receiving streams. Floodwaters also saturate the ground, which leads to infiltration into sanitary sewer lines, or wastewater treatment plants may be flooded or over loaded. When wastewater treatment plants are flooded,there is nowhere for the sewage to flow. Infiltration and lack of treatment can lead to overloaded sewer lines that can back up into low-lying areas and homes. Even when it is diluted by flood waters,raw sewage can be a breeding ground for bacteria such as E.coli and other disease causing agents. Private sewer and septic systems may also introduce pollutants into floodwaters. Private wells may become contaminated through infiltration of polluted water. Given the many potential sources of contamination, direct or indirect contact with floodwaters poses a significant health risk for contraction of infectious disease. — Debris: During a flood, debris carried by floodwaters can cause physical injury from impact. During the recovery process,people may often need to clear debris out of their properties but may encounter dangers such as sharp materials or rusty nails that pose a risk of tetanus. — Unsafe food: If floodwaters come into contact with food items, that food may no longer be safe for consumption due to the potential contaminants in the floodwaters. Foods stored in cardboard,plastic bags,jars,bottles, and paper packaging may all be subject to contamination. Even if foods don't come into direct contact with floodwaters,the introduction of mold and mildew from flooding may cause foods to spoil faster. Additionally,power outages may cause refrigerated and frozen foods to spoil. — Mosquitos and animals: After most of the water has receded, stagnant pools can become breeding grounds for mosquitoes,which may carry infectious diseases such as West Nile virus or St. Louis encephalitis. Wild animals such as snakes or rodents may carried by floodwaters or lose their habitat and seek shelter in buildings. Snakes may also be swimming in floodwaters seeking higher ground. People may be at risk for bites or disease if they come in contact with these animals or animal carcasses. — Mold and mildew: Areas of a building that were exposed to excessive moisture can breed mold and mildew. Molds can start to grow in only 24 to 48 hours and will continue to grow without steps to dry out and disinfect the affected surface. Some molds are allergens,while others can produce harmful mycotoxins. Exposure to mold can cause respiratory problems; nasal and sinus congestion; eye,nose, and throat irritation; aches and pains; and effects on the nervous system. Infants, children, immunocompromised individuals, elderly adults,pregnant women, and individuals with respiratory conditions are all at higher risk. — Reentering a flooded building: Health hazards may occur when heating ducts in a forced air system are not properly cleaned after inundation. When the furnace or air conditioner is turned on, the sediments left in the ducts are circulated throughout the building and breathed in by the occupants. If the public water systems lose pressure,public water supplies may be contaminated, and a boil order may be issued to protect people and animals from contaminated water. — Mental stress: Long-term psychological impacts can result after having been through a flood and seeing one's home damaged and personal belongings destroyed. The cost and labor needed to repair a flood-damaged home can also put a severe strain on people, especially individuals who were li �iii .d ai,4 IIL...o III iii t lii ii iii*.m Strategy J a iii`.m U a iii. .: .6 IIC:.)Eige 9 7 SECTION 4: HAZARD IDENTIFICATION&RISK ASSESSMENT unprepared and uninsured. There is also a long-term problem for those who know that their homes can be flooded again. The resulting stress on floodplain residents takes its toll in the form of aggravated physical and mental health problems. IIII IIII IIII IIII IIII IIII Flood waters may prevent access to areas in need of response or to the critical facilities themselves which may prolong response time. See the Property section below for estimates of critical facility vulnerability. The public must understand that they should never drive through flooded streets. The Centers for Disease Control and Prevention report that over half of flood-related drownings occur when a vehicle is driven into flood water, and the next highest percentage of deaths is due to people walking into or near flood waters. The National Weather Service warns that just 6 inches of fast-moving flood water can knock down an adult, 12 inches can carry away a small car, and 2 feet can carry away most vehicles. When someone drives through floodwaters,they put their life and the lives of first responders at risk. First responders are at risk when attempting to rescue people from floodwaters. They are subject to the same hazards as the public and are more likely to be exposed to these hazards during response efforts. Floods can result in fatalities. Individuals face high risk when driving through flooded streets. According to NCEI records,however,there have been no deaths in Monroe County caused by flood events. An estimate of population at risk to flooding was developed based on the assessment of residential property at risk. Counts of residential buildings at risk were multiplied by a household factor for each jurisdiction, derived from a weighted average of the 2019-2023 American Community Survey's average household size for owner- and renter-occupied housing. The resulting estimates of population at risk are shown in Table 4.25. Overall, approximately 93,541 people live in high-risk flood zones.

FEMA considers loss ratios greater than 10%to be significant and an indicator a community may have more difficulties recovering from a flood. Loss ratios for all participating jurisdictions are at or above 10%. Therefore, in the event of a flood with a magnitude of the 1%-annual-chance event or greater, the planning area would face extreme difficulty in recovery. Even smaller,more probabilistic floods may also result in the county having difficulty recovering. Based on the results using the effective FIRM, estimated loss ratios are greatest in Layton and the unincorporated areas of Monroe County; therefore, these jurisdictions may face the greatest potential impacts from a flood event. Across the planning area there are 388 critical facilities located in the AE zone and 19 facilities located in the VE zone which may be at risk to more severe damages. There are 390 facilities located in the preliminary FIRM's SFHA. Table 4.28 details these critical facilities at risk to flooding by FEMA lifeline based on the effective FIRM and Table 4.29 details results for the preliminary FIRM. There are an additional 19 facilities (effective FIRM)and 43 facilities (preliminary FIRM) in the 0.2%-annual-chance floodplain(Shaded X).

A severe repetitive loss property is classified as such if it has four or more separate claim payments of more than$5,000 each(including building and contents payments) or two or more separate claim payments (building only)where the total of the payments exceeds the current value of the property. Repetitive loss properties and severe repetitive loss properties are a priority for mitigation because they have a known flood risk and are a drain on the NFIP. According to 2024 NFIP records,there are a total of 1,210 repetitive loss properties within the Monroe County planning area. of which 1,079 are residential and 131 are commercial or non-residential. Only 658 repetitive loss properties, less than 54% of the total in the region, are insured. There are 114 properties on the list classified as severe repetitive loss properties. Table 4.30 summarizes repetitive loss properties by jurisdiction in Monroe County as identified by FEMA through the NFIP. Jurisdictional annexes have general areas where repetitive losses have occurred throughout the community.

ENVIRONMENT During a flood event, chemicals and other hazardous substances may end up contaminating local water bodies. Flooding kills animals and in general disrupts the ecosystem. Snakes and insects may also make their way to the flooded areas. Floods can also cause significant erosion, which can alter streambanks and deposit sediment, changing the flow of waterbodies and potentially reducing their drainage capacity. Sea level rise can have numerous negative consequences on the environment including increased erosion and associated impacts. Another concern is the inundation of normally dry land,which could lead to the loss of marshes and wetlands and the positive benefits associated with those areas. These areas buffer against waves and storm surge,protect from erosion and even encourage accretion, and provide natural wildlife habitats. Sea level rise may also lead to saltwater intrusion as the groundwater table may also rise,potentially leading to contaminated drinking and agriculture water. .......................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................

Property, Facilities and Buildings and infrastructure, including transportation and utility Infrastructure infrastructure, may be damaged or destroyed by flooding. Impacts are expected to be localized to the area of the incident.Severe damage is possible. Environment Chemicals and other hazardous substances may contaminate local water bodies.Wildlife and livestock deaths possible.The localized impact is expected to be severe for incident areas and moderate to light for other areas affected by the flood or HazMat spills. Economic Condition of Local economy and finances will be adversely affected, possibly for an the Jurisdiction extended period. During floods(especially flash floods), roads, bridges,farms, houses and automobiles are destroyed.Additionally,the local government must deploy firemen, police and other emergency response personnel and equipment to help the affected area. It may take years for the affected communities to be re-built and business to return to normal. Public Confidence in Ability to respond and recover may be questioned and challenged if the Jurisdiction's planning, response,and recovery are not timely and effective. Governance Natural hazards are often interconnected. Any given hazard may lead to, or be spurred by, another hazard —sometimes referred to as cascading disasters. A flood event may be associated with coastal erosion, tropical storms and hurricanes, storm surge, sea level rise, and severe storms and tornadoes. New development or redevelopment, if it occurs in or near the SFHA or localized flooding areas, could increase exposure of people and property to flood impacts. Additionally, increased development anywhere in the County can create changes in the watershed by increasing impervious surfaces; such development will alter flood patterns as well as intensity of flooding events. This is especially true of increased development within or near identified floodplains. Though the County's Rate of Growth Ordinance determines the speed at which undeveloped parcels may be developed there is still potential for increased impervious surfaces on previously developed parcels. Islamorada, Layton and other locations that are fully built out will not face the same risks as the potential for new development and impervious surface coverage is limited. All incorporated jurisdictions have at least 89 percent of their total land area in the Special Hazard Flood area. Riverine floods could likely significantly impact these jurisdictions. It is important to consider how the recently released preliminary floodplain maps will impact flood insurance once effective. All jurisdictions in the County have a flood loss-ratio of greater than 10%;the loss ratio is higher in unincorporated Monroe (30%)than Countywide (25%). Per the Hazus analysis, 100 percent of developed parcels in the AE and VE zones are at risk to flooding (Key Colony Beach and Layton);Marathon(99.9%) and Islamorada(90.5%)have larger portions of parcels at risk than the County average(89.2%). Mitigation strategies should prioritize these properties. li �iii .d ai,4 IIL...o III iii t lii ii iii*.m Strategy J a iii`.m U a iii. .: .6 SECTION 4: HAZARD IDENTIFICATION&RISK ASSESSMENT As a community with a large seasonal population,the County and incorporated jurisdictions should consider whether shelters have adequate capacity for this influx of people, often during hurricane season. Less than 50%of repetitive loss buildings in Key Colony Beach(42%), Layton(0%), and unincorporated Monroe (47%) are insured. These buildings should be prioritized for elevation or acquisition. Localized and stormwater flooding blocking roadways (particularly U.S. Highway 1) may impede evacuation capabilities. Of the 430 critical facilities reported in this plan, 90 percent are within the effective SFHA; 86.2 percent in the AE zone and 4.4 percent in the VE zone. The communities must identify mitigation strategies that protect these facilities,which might include elevation of critical systems, elevation of the building, floodproofing, or relocation, among others. The following table summarizes flood hazard risk by jurisdiction. Flood risk due to high tide flooding, flash flooding, and stormwater flooding exists across the entire county. All participating jurisdictions have over 89 percent of their area in the SFHA and thus have a high degree of exposure to flooding; given that other sources of flooding and other levels of flooding may occur beyond these areas,the spatial extent was considered large for all jurisdictions. Impact ratings were based upon Hazus loss estimates as well as the overall risk of death or injury; all jurisdictions have loss ratios over 10. All communities also face a uniform probability of flooding.

Sea level rise is a result of global climate change. Climate change may be due to natural internal processes or external forces such as modulations of the solar cycles,volcanic eruptions, and persistent anthropogenic changes in the composition of the atmosphere or in land use(IPCC, 2023). Climate change is a natural occurrence in which the earth has warmed and cooled periodically over geologic time. The recent and rapid warming of the earth over the past century has been cause for concern as it is very likely due to the accumulation of human-caused greenhouse gases, such as CO2, in the atmosphere (IPCC, 2023). This warming is occurring almost everywhere in the world which suggests a global cause rather than changes in localized weather patterns. In 2023,the Intergovernmental Panel on Climate Change(IPCC) reported with high confidence that warming due to such emissions will cause long-term changes in the climate system such as sea level rise. There are generally two separate mechanics involved in global sea level rise. The first is directly attributed to global temperature increases,which warm the oceans waters and cause them to expand. The second is attributed to the melting of ice over land which simply adds water to the oceans. Global sea level rise is likely caused by a combination of these two mechanics and can be exacerbated on the local level by factors such as erosion and subsidence. The rate of sea level rise has varied throughout geologic history, and studies have shown that global temperature and sea level are strongly correlated. Due to sea-level rise projected throughout the 21 st century and beyond, coastal systems and low-lying areas will increasingly experience adverse impacts such as submergence, coastal flooding, and coastal erosion. The population and assets projected to be exposed to coastal risks as well as human pressures on coastal ecosystems will increase significantly in the coming decades due to population growth, economic development, and urbanization(IPCC, 2023). Monroe County is particularly vulnerable to the effects of sea level rise, due to its coastal location, subtropical environment, low topography and tourism economy. Warning Time: 1 —More than 24 hours Duration: 4—More than one week Sea level rise can occur anywhere along the coast in Monroe County. The Coastal Vulnerability Index (CVI), developed by United States Geological Survey(USGS),provides a preliminary overview of the relative susceptibility of the United States coast to sea level rise. The CVI is based on geomorphology, regional coastal slope, tide range,wave height,relative sea level rise, and shoreline erosion and acceleration rates. For each study area, each variable is scored on a 1-5 scale based on defined parameters, where "1"indicates low contribution to coastal vulnerability and"5"indicates high contribution to vulnerability. These scores are then aggregated into a single index through a mathematical formula. The resulting index gives an overview of where physical changes may occur due to sea-level rise. Figure 4.12 shows the CVI for Monroe County. Most of the Florida Keys have a CVI rating of high, except Big Torch Key and Howe Key, which are rated moderate. The mainland coastline is also rated moderate.

The NOAA Sea Level Rise Viewer provides a tool to examine potential sea level rise (SLR) scenarios which represent possible future sea level changes. This allows users to examine the feet of relative sea level rise for a given year and SLR scenario (low, intermediate,high,etc.). These scenarios were developed and used as inputs into the U.S. Global Change Research Program's Sustained Assessment process and the Fifth National Climate Assessment. The estimated impacts of 2040 projected sea level rise (SLR) for the intermediate-low scenario and the intermediate—high scenario are shown in Figure 4.13 and Figure 4.14,respectively. Both scenarios were also used in the Monroe County Vulnerability Assessment to evaluate risks and vulnerabilities of the County's infrastructure. The sea level rise estimate maps show inundation above mean higher high water (the average of each day's higher high tide line). Maps of sea level rise impacts by jurisdiction are available in individual jurisdictional annexes. As shown in the figures below,under the 2040 intermediate-low scenario the majority of the Keys is estimated to be inundated, and an even larger extent is impacted in the intermediate-high scenario. Sea level rise will likely affect coastal marsh lands as well as land along rivers, canals, and their tributaries. Additionally, sea level rise will likely increase future risk of flooding from the other flood hazards discussed in this plan, as more land will have a lower elevation relative to sea level. For example,with much of the barrier islands and wetlands inundated, inland areas will lose their natural protection and may become susceptible to coastal flooding with velocity wave action. li �iii .d ai,4 IIL...o III iii t lii ii iii*.m Strategy J a iii`.m U a iii. .: .6 IIC:)I g,m"III.'6 C1, W r." rN CO CD w11,111,111, A 13) 1`0 ............................................................................................................................................................................................................................................................................................................................................................................................................. ci .........I............. .,......... ............. ............

However, sea level rise has already begun to cause"clear sky"or"nuisance" flooding,which is brought on by high tidewaters rather than storm or rain events. Tidal flooding causes temporary inundation of low-lying areas during high-tide events. The 2022 NOAA Sea Level Rise Technical Report finds that the national rate of high-tide flooding has more than doubled since 2000 due to sea level rise.NOAA projects that by 2050 high tide flooding events will occur 45 to 70 days a year,triple the current rate. While sea level rise increases the frequency of these events, it also is expected to increase the depth and extent of tidal flooding. Figure 4.15 shows areas in Monroe County that are susceptible to high tide flooding as defined by NOAA based on derived national flood thresholds from NOAA Technical Report NOS CO-OPS 086: Patterns and Projections of High Tide Flooding along the U.S. Coastline Using a Common Impact Threshold.

The Center for Operational Oceanographic Products and Services (CO-OPS)has been measuring sea level for over 150 years,with tide stations operating on all U.S. coasts. Changes in Mean Sea Level (MSL), either a sea level rise or sea level fall, have been computed at 142 long-term water level stations using a minimum span of 30 years of observations at each location. These measurements have been averaged by month to remove the effect of higher frequency phenomena(e.g. storm surge) in order to compute an accurate linear sea level trend.

As such,the trend misses subtle variations and especially larger increases as climate change and CO2 levels have increased in recent years. Per the Southeast Florida Regional Climate Change Compact's Unified Sea Level Rise Projection 2019 Update,this linear trend estimates approximately 2 inches of sea level rise at the Key West, FL tide gauge from 2000 through 2019. However,using 5-year averages of mean sea level,this estimate is closer to 3.9 inches of sea level rise from 2000 to 2017. This 5-year average of monthly mean sea level illustrates the variability of sea level and highlights the increase in sea level above the linear trend, especially in the last decade. Figure 4.19 from the Unified Projection document illustrates these variations by displaying monthly mean sea level, 5-year averages of mean sea level, and the linear mean sea level trend.

Climate Central's Surging Seas Risk Finder notes that coastal floods are increasing. Figure 4.20 shows coastal flooding in the Key West Area(based on the Key West water level station) from 1955 through 2014 in 10-year increments. According to this data, from 1995 through 2004,the Key West area experienced 8 coastal flood days—seven of which were driven by climate-linked sea level rise. In the following 10 years, from 2005 through 2014,the number of coastal flood days increased to 32, a 300 percent increase. 30 of these coastal flood days can be attributed to climate-linked sea level rise.

King tides are predictable phenomenon that generally occur each fall when the alignment of the moon, sun, and Earth create a stronger gravitational pull on the ocean. Like many other coastal events, climate change has made King Tide flooding worse. In the Fall of 2019,the Upper Florida Keys experienced nearly three months of King Tide flooding,particularly in the Blackwaters Sound area. That year, Hurricane Dorian and other tropical storms in late August and early September interrupted the Gulf Stream, causing water to back up. Tides recorded along the Atlantic coast from the Carolinas to Florida were 6 to 18 inches higher than expected. Residents noted that in these low-lying areas with nowhere for water to drain,these events generally lasted seven to ten days in the past. In 2024,the peak king tide occurred during the super full moon in mid-October,which was the closest the moon came to the Earth during the whole year. The Earth's changing climate will continue to drive nonlinear trends in Sea Level that deviate from historic trends. This is especially pertinent in the coastal communities of South Florida on the frontlines of climate change and sea level rise and is the reason behind the South Florida Regional Climate Change Compact's Unified Sea Level Rise Projection. This document was created in unify the diversity of local Sea Level Rise projections in order to create a single, unified projection to ensure consistency in adaptation planning,policy, and infrastructure and siting design in the South Florida region. The first unified projection was developed and released in 2011,updated in 2015, and most recently updated in 2019. Each update has incorporated new research and data. The 2019 update incorporated the potential �A('Irvrc)e courity, fllscfi�cda,4 IIL...o III itigat'ar'i Strategy &i. 2(`)26 C:.)Eige 13 SECTION 4: HAZARD IDENTIFICATION&RISK ASSESSMENT for faster rates of melting of the Antarctic Ice Sheet as well as regional sea level rise rates as reported in the Fourth National Climate Assessment. It should be noted that in December of 2024,the South Florida Regional Climate Change Compact's Unified Sea Level Rise Projection issued a statement of continued use of the 2019 version as a full 5-year update and revision was not deemed necessary. The 2019 update begins in the year 2000, as this is the reference year for the most recently published NOAA projections, and uses two planning horizons: 20 years for land use (2040) and 50 years for infrastructure(2070). The projection used the Key West gauge as the reference gauge to maintain consistency with prior projections. The compact used three curves to guide various development across different time frames in the region. Importantly,the projections are regional rather than previously used global projections. The projections are as follows: — Short term: by 2040, sea level in the region is projected to rise 10 to 17 inches above 2000 mean sea level. — Medium term: by 2070, sea level in the region is projected to rise 21 to 54 inches above 2000 mean sea level. — Long term: by 2120, sea level in the region is projected to rise 40 to 136 inches above 2000 mean sea level. These projections are based on three global curves adapted for regional application: the median of the IPCC AR5 RCP 8.5 scenario as the lowest boundary, the NOAA Intermediate High Curve as the upper boundary for short term use (until 2070) and the NOAA High Curve as the upper boundary for medium and long-term use. Figure 4.21 below shows these projections. The IPCC Median Curve and the NOAA Intermediate High curve form the lower and upper bounds,respectively, for short-term use (through 2070). The IPCC median curve represents the most likely average sea level before 2070; sea level is rise is unlikely to exceed the NOAA Intermediate High curve by 2100. The NOAA High curve forms the upper bound for medium- and long-term use. Sea level rise is very unlikely to be higher than this curve before 2100.

The projections are to be used by a variety of audiences,including elected officials,urban planners, engineers, and developers, among others, across short-and long-term planning horizons for new projects or adaptation of existing projects, including infrastructure siting and design. The projection is an important complement to a vulnerability assessment in order to inform the user of the potential magnitude and extent of sea level rise now and into the future using various scenarios with associated timelines. In making infrastructure siting decisions, users must consider the nature,value, interconnectedness, and lifespan of existing and proposed infrastructure. The following summarizes the Unified Projection's recommendations for application of the three curves: IPCC Median Curve: The lower bound of the projection; can be applied to most infrastructure projects before 2070 or whose failure would result in limited consequence to others. NOAA Intermediate High Curve: Consider designing to this curve for projects in need of a greater factor of safety; this includes projects with a design life beyond 50 years. NOAA High Curve: Existing and proposed critical infrastructure should be elevated using this curve; projects that are not easily replaceable,have a long design life, and are interdependent with other infrastructure or services are included in this application. As noted in the 2024 Statement of Continued Use of the 2019 Southeast Florida Regionally Unified Sea Level Rise Projection, the Compact reviewed updates from the NOAA 2022 Sea Level Rise Technical Report as well as observational trends of sea level in the region. In the NOAA 2022 Report,it was shown that the projections for the year 2100 for each global scenario stayed the same as previous predictions.

Estimates for sea level rise are based on projected greenhouse gas emission levels and their associated impacts on global temperature change. Most sea level rise models do not fully account for ice melt, and therefore actual sea level rise may be significantly higher than current estimates suggest. As such,these projections contain substantial variability but are nonetheless important to consider when planning for coastal areas because they indicate where flooding can be expected should actual sea level rise meet estimated levels. .......................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................

PROPEPTY The increased number of flood days and general encroachment of shoreline associated with sea level rise will likely cause property damage, although it is unclear exactly what this will look like. Homes, businesses and vehicles will be susceptible to increased water damage. Homes within the areas that may be inundated will potentially be uninhabitable. Additionally,rising seas, and associated increased flood days, can overwhelm and undermine the effectiveness of stormwater drainage system and other infrastructure, such as roads and bridges. Table 4.32 estimates the number of parcels at risk to the 2040 intermediate—low and intermediate—high SLR scenarios.

Further saltwater intrusion into the aquifer will impact the entire Monroe County population as it relies on drinking water from this source. ....................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................... Sea level rise can have numerous negative consequences on the environment including increased erosion and all impacts associated with that. Another concern is the inundation of normally dry land,which could lead to the loss of marshes and wetlands and the positive benefits associated with those areas. These areas buffer against waves and storm surge,protect from erosion and even encourage accretion, and provide natural wildlife habitats. Finally, sea level rise may lead to saltwater intrusion as the groundwater table may also rise,potentially leading to contaminated drinking and agriculture water. .......................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................

Public Confidence in the Sea level rise is unlikely to impact public confidence. Jurisdiction's Governance Natural hazards are often interconnected. Any given hazard may lead to, or be spurred by, another hazard —sometimes referred to as cascading disasters. Sea level rise may be associated with tropical cyclones, storm surge, flood, and coastal erosion. New development at a local scale will not necessarily impact the rate of sea level rise. Increased development in potentially inundated areas,however,will increase vulnerability.

Residential property is most likely to be affected by sea level rise,which has implications on a local economy—both permanent and season residential units may no longer be livable. Education and outreach programs could increase residential and property owner buy-in on and implementation of mitigation options on an individual property scale. Various reports on sea level rise in the region exist—mitigation strategies should consider all reports; specifically detailing critical facilities at risk to sea level rise using a standard prediction would clarify mitigation strategies chosen to respond to this hazard. Key West,Marathon, Layton, and Unincorporated Monroe County will have the most parcels impacted by 2 feet of sea level rise. The following table summarizes sea level rise risk by jurisdiction. The coastal, low-lying geography of the region mean all jurisdictions face at least some risk from sea level rise.

S Thunderstorms result from the rapid upward movement of warm, moist air. They can occur inside warm, moist air masses and at fronts. As the warm,moist air moves upward, it cools, condenses, and forms cumulonimbus clouds that can reach heights of greater than 35,000 ft. As the rising air reaches its dew point, water droplets and ice form and begin falling the long distance through the clouds towards earth's surface. As the droplets fall, they collide with other droplets and become larger. The falling droplets create a downdraft of air that spreads out at earth's surface and causes strong winds associated with thunderstorms. There are four ways in which thunderstorms can organize: single cell, multi-cell cluster,multi-cell lines (squall lines), and supercells. Even though supercell thunderstorms are most frequently associated with severe weather phenomena,thunderstorms most frequently organize into clusters or lines. Warm,humid conditions are favorable for the development of thunderstorms. The average single cell thunderstorm is approximately 15 miles in diameter and lasts less than 30 minutes at a single location. However, thunderstorms, especially when organized into clusters or lines, can travel intact for distances exceeding 600 miles. Thunderstorms are responsible for the development and formation of many severe weather phenomena, posing great hazards to the population and landscape. Damage that results from thunderstorms is mainly inflicted by downburst Winds, large hailstones, and flash flooding caused by heavy precipitation. Stronger thunderstorms can produce tornadoes and waterspouts. While conditions for thunderstorm conditions may be anticipated within a few hours, severe conditions are difficult to predict. Regardless of severity, storms generally pass within a few hours.

LIGHTNING Lightning is a sudden electrical discharge released from the atmosphere that follows a course from cloud to ground, cloud to cloud, or cloud to surrounding air,with light illuminating its path. Lightning's unpredictable nature causes it to be one of the most feared weather elements. All thunderstorms produce lightning,which often strikes outside of the area where it is raining and is known to fall more than 10 miles away from the rainfall area. When lightning strikes, electricity shoots through the air and causes vibrations creating the sound of thunder. A bolt of lightning can reach temperatures approaching 50,000 degrees Fahrenheit. Nationwide, lightning kills 75 to 100 people each li �iii .d aii­4 IIL...o III iii t lii ii iii*.m Strategy J a iii`.m U a iii. .: .6 IIC:)�g,m"II2 SECTION 4: HAZARD IDENTIFICATION&RISK ASSESSMENT year. Lightning strikes can also start building fires and wildland fires, and damage electrical systems and equipment. The watch/warning time for a given storm is usually a few hours. There is no warning time for any given lightning strike. Lightning strikes are instantaneous. Storms that cause lightning usually pass within a few hours.

HAI L According to the National Oceanic and Atmospheric Administration(NOAA),hail is precipitation that is formed when updrafts in thunderstorms carry raindrops upward into extremely cold areas of the atmosphere causing them to freeze. The raindrops form into small frozen droplets and then continue to grow as they encounter super-cooled water which will freeze on contact with the frozen rain droplet. This frozen rain droplet can continue to grow and form hail. If the updraft forces can support or suspend the weight of the hailstone,hail can continue to grow. At the time when the updraft can no longer support the hailstone, it will fall to the earth. For example, a 1/4" diameter or pea sized hail requires updrafts of 24 mph,while a 2 3/4"diameter or baseball sized hail requires an updraft of 81 mph. The largest hailstone recorded in the United States was found in Vivian, South Dakota on July 23, 2010; it measured eight inches in diameter, almost the size of a soccer ball. While soccer-ball-sized hail is the exception,but even small pea sized hail can do damage. Hailstorms in Florida cause damage to property, crops, and the environment, and kill and injure livestock. In the United States,hail causes more than$1 billion in damage to property and crops each year. Much of the damage inflicted by hail is to crops. Even relatively small hail can shred plants to ribbons in a matter of minutes. Vehicles,roofs of buildings and homes, and landscaping are the other things most commonly damaged by hail. Hail has been known to cause injury to humans; occasionally,these injuries can be fatal. The onset of thunderstorms with hail is generally rapid. However, advancements in meteorological forecasting allow for some warning. Storms usually pass in a few hours. Warning Time: 4—Less than 6 hours Duration: I —Less than 6 hours ....................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................... According to the Glossary of Meteorology(AMS 2000), a tornado is "a violently rotating column of air, pendant from a cumuliform cloud or underneath a cumuliform cloud, and often(but not always)visible as a funnel cloud." Tornadoes can appear from any direction. Most move from southwest to northeast, or west to east. Some tornadoes have changed direction amid path, or even backtracked. Tornadoes are commonly produced by land falling tropical cyclones. Those making landfall along the Gulf coast traditionally produce more tornadoes than those making landfall along the Atlantic coast. Tornadoes that form within hurricanes are more common in the right front quadrant with respect to the forward direction but can occur in other areas as well. According to the NOAA,more than half of the landfalling hurricanes will spawn at least one tornado. Tornadoes are more likely to be spawned within 24 hours of landfall and are usually within 30 miles of the tropical cyclone's center. Tornadoes have the potential to produce winds in excess of 200 mph(EF5 on the Enhanced Fujita Scale) and can be very expansive—some in the Great Plains have exceeded two miles in width.

Joseph Golden,the distinguished waterspout authority with NOAA, defines a waterspout as a"funnel which contains an intense vortex, sometimes destructive, of small horizontal extent and which occurs over a body of water."In other words, a waterspout is a column of rotating, cloud-filled wind. There are two types of waterspouts. A tornadic waterspout generally begins as a true tornado over land in association with a thunderstorm and then moves out over water. They are influenced by winds associated with severe thunderstorms as air rises and rotates on a vertical axis.Fair weather waterspouts, on the other hand, are associated with developing storms systems,but not storms themselves. These types of waterspouts only form over open water,where they develop at the water's surface and climb skyward. Both types of waterspouts require high levels of humidity and relatively warm water temperatures compared to overlying air. The fair-weather variety is more common than the tornadic type. There are five stages of waterspout formation: Dark Spot: The water's surface takes on a prominent circular, light-colored disk surrounded by a larger dark area of indeterminate shape with diffused edges where the vortex reaches it. Spiral Pattern: A pattern of light and dark colored surface bands spiral out from the dark spot. Spray Ring: A swirling ray of dense sea spray,known as a cascade, forms around the dark spot with what appears to be an eye similar to that seen in hurricanes. Mature Vortex: This is the waterspouts most intense stage. It is now visible from the water surface to an overhead cloud mass as it achieves maximum organization and intensity. The funnel often appears li �iii .d ai,4 IIL...o III iii t lii ii iii*.m Strategy J a iii`.m U a iii. .: .6 SECTION 4: HAZARD IDENTIFICATION&RISK ASSESSMENT hollow,with a surrounding shell of turbulent condensate. The spray vortex can rise to a height of several hundred feet or more, often creating a visible wake and an associated wave train as it moves. Decay: The funnel and spray vortex begin to dissipate as the inflow of warm are into the vortex weakens. Systems that might produce waterspouts are outline in the National Weather Service's nearshore marine forecast and hazardous weather outlook, and this information is shared 12 to 24 hours prior to waterspout occurrences.NWS will issue a special marine warning when waterspouts are detected by doppler radar or trained spotters.

HUNDERSTOPINI WINDS Thunderstorm wind, lightning, and hail events do not have a defined vulnerability zone. The scope of wind, lightning and hail is generally defined to the footprint of its associated thunderstorm. Given the general size and movement of thunderstorm events, thunderstorm winds from one event may impact a large portion of the planning area. The entirety of Monroe County and its jurisdictions share equal risk to the threat of severe weather.

Tornados can occur anywhere in the County. Tornadoes typically impact a small area,but damage may be extensive. Tornado locations are completely random,meaning risk to tornado isn't increased in one area of the county versus another. Monroe County and its jurisdictions are uniformly exposed to tornadoes. Waterspouts are most common in tropical and subtropical waters such as the Florida Keys, Greek Islands, or off the coast of Australia. Waterspouts can occur in any of the water bodies in Monroe County.

SECTION 4: HAZARD IDENTIFICATION&RISK ASSESSMENT LIGHTNING AND HAIL The scope of lightning and hail is generally defined to the footprint of its associated thunderstorm. However, large-scale hail tends to occur in a more localized area within the storm, and lightning strikes and associated damages are highly localized and occur randomly. It should be noted that while lightning is most often affiliated with severe thunderstorms, it may also strike outside of heavy rain and might occur as far as 10 miles away from any rainfall. The entirety of Monroe County and its jurisdictions are uniformly exposed to each of these hazards. According to the Vaisala Interactive Global Lightning Density Map, shown in Figure 4.26,the majority of Florida experiences 32-641ightning events per square kilometer per year. The Florida Keys do experience slightly less lightning on average at 16-32 events per square kilometers per year.

For this severe weather risk assessment, High Wind, Strong Wind and Thunderstorm Wind data was collected. Hurricane Wind and Tornadoes are addressed as individual hazards. The following definitions come from the NCEI Storm Data Preparation document. Monroe County,FL WSP Multi-Jurisdictional Local Mitigation Strategy January 2026 Page 126 SECTION 4: HAZARD IDENTIFICATION&RISK ASSESSMENT — High Wind—Sustained non-convective winds of 40mph or greater lasting for one hour or longer or winds (sustained or gusts) of 58 mph for any duration on a widespread or localized basis. — Strong Wind—Non-convective winds gusting less than 58 mph, or sustained winds less than 40 mph,resulting in a fatality, injury, or damage. — Thunderstorm Wind—Winds, arising from convection(occurring within 30 minutes of lightning being observed or detected),with speeds of at least 58 mph, or winds of any speed(non-severe thunderstorm winds below 58 mph)producing a fatality, injury or damage. The Beaufort Wind Force Scale shown in Table 4.34 is an empirical measure that relates wind speed to observed conditions at sea or on land. In the United States,winds of force 6 to 7 are designated as "strong;" 8 to 9 "gale force;" 10 to 11 "usually results in a storm warning or tropical storm warning; and force 12 results in a hurricane warning. °°°' IIIIIII�IIIIIII °°"""°° IIIIIII° t lilt rid ce Sc6II e Rating (MPH) Name Appearance of Wind Effects On Water On Land 0 <1 Calm Sea surface smooth and mirror- Calm,smoke rises vertically like 1 1-3 Light Air Scaly ripples, no foam crests Smoke drift indicates wind direction,still wind vanes 2 4-7 Light Small wavelets,crests glassy, no Wind felt on face, leaves rustle, Breeze breaking vanes begin to move 3 8-12 Gentle Large wavelets,crests begin to Leaves and small twigs constantly Breeze break,scattered whitecaps moving, light flags extended 4 13-18 Moderate Small waves 1-4 ft, becoming Dust, leaves,and loose paper lifted, Breeze longer, numerous whitecaps small tree branches move 5 19-24 Fresh Moderate waves 4-8 ft taking Small trees in leaf begin to sway Breeze longer to form, many whitecaps, some spray 6 25-31 Strong Larger waves 8-13 ft,whitecaps Larger tree branches moving, Breeze common, more spray whistling in wires 7 32-38 Near Gale Sea heaps up,waves 13-19 ft, Whole trees moving,resistance felt white foam streaks of breakers walking against wind 8 39-46 Gale Moderately high (18-25 ft)waves Twigs breaking off trees,generally of greater length,edges of crests impedes progress begin to break into spindrift, foam blown in streaks 9 47-54 Strong High waves(23-32 ft),sea begins Slight structural damage occurs, Gale to roll,dense streaks of foam, slate blows off roofs spray may reduce visibility 10 55-63 Storm Very high waves(29-41 ft)with Seldom experienced on land,trees overhanging crests,sea white broken or uprooted,"considerable with densely blown foam, heavy structural damage" rolling, lowered visibility 11 64-72 Violent Exceptionally high (37-52 ft) Very rarely experienced; Storm waves,foam patches cover sea, widespread damage visibility more reduced IIP �i �i .��i � � I i�l tii'i i*.m Strategy y a iii`.m U a iii. .: .6 SECTION 4: HAZARD IDENTIFICATION&RISK ASSESSMENT Rating (MPH) Name Appearance of Wind Effects On Water On Land 12 73+ Hurricane Air filled with foam,waves over Devastation 45 ft,sea completely white with driving spray,visibility greatly reduced Source:NOAA Storm Prediction Center The strongest recorded thunderstorm wind event in the county occurred on February 2, 1998 when a C- MAN instrument recorded a peak wind speed of 119 mph at Long Key.

Prior to February 1, 2007, tornado intensity was measured by the Fuj ita(F) scale. This scale was revised and is now the Enhanced Fuj ita(EF) scale. Both scales are sets of wind estimates(not measurements) based on damage. The new scale provides more damage indicators (28) and associated degrees of damage, allowing for more detailed analysis,better correlation between damage and wind speed. It is also more precise because it takes into account the materials affected and the construction of structures damaged by a tornado. Table 4.38 shows the wind speeds associated with the enhanced Fujita scale ratings and damage that could result at different levels of intensity. °°° Illlllh lllllll °°"° IIIIIII IIIIIII IIIIIII IIIIIII � IIIIIII °t IIIIIII EF 3 Second Number Gust(mph) Damage 0 65-85 Light damage.

There is no scale comparable to the Fuj ita scale to measure the strength of a waterspout, however they generally are not expected to cause injury, death, or damage to residents or property in Monroe County. Waterspouts might be measured by their radius or wind speeds. An average waterspout is around 165 feet in diameter with wind speed around 50 mph, corresponding with an EFO tornado, and last on average 5 to 10 minutes. Larger waterspouts might have a maximum 330-foot diameter and can last as long as one hour. An October 2011 waterspout caused$10,000 in damages when it moved through the anchorage at Key West Harbor and damaged a vessel's cabin and hull after driving it ashore.

The strike survivor remained conscious and was treated at Lower Key Medical Center for minor injuries. July 22,2012—A positive-polarity lightning strike struck a residence in Key West within stratiform rainfall behind a northwest-moving squall line. The residence, a duplex,was severely damaged. The lightning struck the ground near the exterior j acuzzi in a side yard,near the front corner of the structure, leaving a hole in the ground roughly 2 feet by 2 feet and 18 inches deep. A ground rod and wire was installed for the Jacuzzi but not attached. The charge followed the exterior power conduit to an exterior junction box, where the box's cover was blown free. Wires were charred,the conduit destroyed. The residence's washer/dryer electric supply was charred. The electric meter box exploded with wires charred and burned and all connections melted. In the front of the residence,wood was charred under metal screws securing the exterior soffit. Aluminum window frames in the front of the residence were melted with windows knocked out. Light bulbs in various locations throughout the residence were blown, including the bedroom lamps and ceiling fixture,bathroom wall fixture, and kitchen ceiling light fixture. The bathroom mirror was shattered. The residence was declared unfit for occupation due to damage to the electrical system, although no fire resulted. Keys Energy Services replaced a blown fuse for a transformer serving the residence, and three other residences had tripped circuits but no permanent damage was reported. The struck residence was occupied by one female at the time of the strike,who was observed by rescue personnel to not have any injuries. November 2,2018—An isolated thunderstorm near the lower Florida Keys produced a damaging lightning strike to a residence on Barbados Lane on Ramrod Key. The strike resulted in roof and electrical system damage. A neighboring residence also experienced electrical system damage. ....................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................... HAI L NCEI records 7 separate hail incidents across 3 days between January 1, 2000 and December 31, 2024 in Monroe County. Of these, one event resulted in$250 in property damage, and no events resulted in death, injury or crop damage. The largest diameter hail recorded in the County was 1.75 inches,which occurred on April 27, 2003 in Key West. This was the largest hail ever reported since record began in 1871. The event was only the 11 th time hail of any size had been recorded in Key West. The average hail size of all events in the County was just under over one inch in diameter.

June 13,2007—A severe thunderstorm moved south out of Miami-Dade County on the mainland, crossed the east end of Florida Bay, and produced sporadic wind damage throughout North Key Largo, Key Largo and Rock Harbor. A landscaper reported 3/4 inch hail in Rock Harbor. June 15,2013—A surface frontal boundary moved into South Florida during the afternoon and generated numerous to widespread severe thunderstorms during the afternoon and early evening some with very large hail. Hail up to the size of baseballs and slightly larger was reported from two separate thunderstorms and this is only the sixth time since 1950 that baseball sized hail or larger has been reported anywhere in South Florida. A spotter reported nickel sized hail at the Loop Road Education Center. ....................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................... ORNADOES NCEI storm reports were reviewed from 2000 through 2024 to assess whether recent trends varied from the longer historical record.According to NCEI, Monroe County experienced 32 tornado incidents between 2000 and 2024, causing over$5.3 million in property damage but no injuries, fatalities, or crop damage. $5 million in damages came from one F2 event in Marathon on August 26, 2005. However,this damage estimate may be under reported, as damage was reported in the narratives of many events but was not recorded in terms of a monetary value.

Specific incidents with some level of impact include: July 1,2000—A waterspout moved onshore along the south end of Big Pine Key. The event resulted in damage to a bed and breakfast inn. August 26,2005—Tornado damage path began at the oceanfront at 73rd Street Ocean(F 1)in Marathon and moved northeast, crossing U.S. Highway 1 near 76th Street Ocean,passing through Marathon Airport before entering Florida Bay near the Sea Air Estates Subdivision. The most significant damage(F2) included concrete block residential structure shifted on foundation, A-frame residence shifted on pilings, and bent large steel I-Beams on recently constructed hangars at Marathon Airport. One boat sunk in canal. Extensive damage to porches and trees along narrow path. Damage from this tornado totaled$5 million. September 9 & 10,2008—Hurricane Ike moved west to west-northwest across eastern Cuba,just offshore the south-central coast, and then crossed through western Cuba into the Gulf of Mexico. Tropical storm force winds and two tornadoes were reported in the Florida Keys. Damage from these tornadoes totaled$145,000. The first tornado touched down on the Atlantic side of U.S. Highway One and moved toward the northwest. The tornado caused minor damage to facia on a business on the bayside of U.S. Highway One, then moved into a residential area. One residence had two broken windows and another residence had an exterior wall penetrated with a 2x4 carried from a home under construction over 250 yards. Several trees and large limbs downed. Estimated maximum wind speed 60 to 70 mph. The second tornado occurred when a violent waterspout associated with a supercell made landfall in Lower Matecumbe Key at Sunset Drive and moved northwest,crossing U.S. Highway One and then along Palm Drive through a residential section near Mile Marker 74 on the Overseas Highway. The tornado damage path ended on Buttonwood Lane before reaching Florida Bay. Most damage was to deck railings, screens,windows and soffits on numerous homes. A few homes displayed more significant damage, including penetration through exterior doors and walls,with one home losing 50 percent of its roof decking. The EF 1 rating with estimated maximum wind speeds of 90 to 100 mph was based on roof li �iii .d ai,4 IIL...o III iii t lii ii iii*.m Strategy wi"m �&i. .: .6 SECTION 4: HAZARD IDENTIFICATION&RISK ASSESSMENT damage to a residence along Palm Drive. Debris from sheet metal paneling and mangrove branches may have contributed to a major power outage throughout all of the Keys from Islamorada through Key West as it was carried across U.S. Highway One and a major electrical transmission line. December 18,2009—A supercell thunderstorm tracked northeast along the Florida Keys. The thunderstorm first produced a weak tornado at the extreme southeast tip of Key West and south Stock Island,then tracked northeast just north of Big Pine Key before crossing the Upper Florida Keys from the west-southwest at Key Largo. A second weak tornado was reported at several Florida Bay shoreline properties. A weak tornado produced EFO damage across the extreme southeast part of Key West through south Stock Island. The tornado was first observed by a motorist just offshore South Roosevelt Boulevard before moving briefly onshore at a hotel. Over a half dozen palm trees with some decay were snapped at the base. Lawn furniture was blown southeast in the tornado's wake. The tornado tracked northeast across Cow Key Channel before moving ashore again on south Stock Island along 12th Avenue. Two trees were downed, and a deck umbrella was lofted northeast from the east end of 11 th Avenue onto power lines on 5th Street,bringing down the lines and causing a power outage throughout the area. The tornado continued northeast and likely lifted or dissipated over 5th Avenue northeast of Bernstein Park where a small ornamental tree was found snapped at the base and several trashcans had fallen and rolled to the south or southeast. At the tornado's northeast terminus, a television cable line was downed. Maximum winds were estimated at 60 to 70 mph along the path from Key West through 11 th Avenue in Stock Island. The same supercell also caused a short-lived weak tornado near Mile Marker 104 of the Overseas Highway. The tornado produced minor damage with some outdoor furniture destroyed and ornamental palm trees downed in a parking lot at a Florida Bay-side business, and porch screens blown out at a restaurant next door. Maximum winds estimated at 65 mph. April 26,2010—A waterspout accompanying a line of severe thunderstorms moved onshore the Florida Bay side of Key Largo at the Marriott Florida Bay Resort. A tree was blown down blocking part of U.S. Highway 1 in front of the hotel. An outdoor day spa consisting of a thatched roof and bamboo shutters and interior mirrors was destroyed. Weighted deck loungers were blown across the pool deck and significant landscaping damage occurred on the waterfront side of the hotel. The tornado quickly dissipated over U.S. Highway 1. Estimated maximum winds were near 70 mph. April 5,2013—A complex surface low pressure system supported by a sharp upper trough of low pressure extending southward into the Gulf of Mexico produced strong thunderstorms in the Florida Straits. One thunderstorm produced a waterspout which moved ashore along the oceanside of Long Beach Drive and passed over a bed-and-breakfast inn at its maximum intensity and width of about 80 yards. Widespread damage to large limbs of native hardwood trees occurred, and one royal palm snapped at a level above 15 feet. A ground deck with four kayaks became airborne and dropped in mangroves 30 yards away. A large unmounted above-ground cistern containing nearly 200 gallons of water slid over 15 yards, knocking a large camping trailer off its front mount. Bolts securing a large grill to wood ground decking were sheared off. While numerous tables and lounge chairs were carried to the leeward side of the property, one 40-lb steel lounge chair was lifted to the edge of the roof line of the two-story residence, crushing the rain gutter,before settling in the lee of the structure. Small gravel and pea rock along the waterfront caused moderate to severe paint chipping on the oceanside of several homes. Screens including their wood frames were torn off several residences'oceanside porches,with one home losing about 40 percent of its oceanside vinyl siding. A phone line was downed along Long Beach Drive. The tornado continued across mud flats along the southeast edge of Coupon Bight,where only isolated damage to mangrove branches was observed. Small limbs were observed downed across Long Beach Drive between Southeast Point and U.S. Highway 1, eventually crossed through a campground just south IIP �i �i .��i � � I i�l tii i*m Strategy y wi"m �&i. .: .6 IIC: g,m"III SECTION 4: HAZARD IDENTIFICATION&RISK ASSESSMENT of the Spanish Harbor Channel Bridge. Several tents including one large aluminum-framed dome tent structure were overturned before the tornado likely passed into Spanish Harbor Channel. The intensity of the tornado at Spanish Harbor Channel had decreased since its original landfall with estimated winds near 60 mph. April 15,2018—A fast-moving pre-frontal squall line passing through the upper Florida Keys developed an embedded supercell thunderstorm along the Florida Bay side of Upper Matecumbe Key. The supercell thunderstorm moved east-northeast,producing a waterspout which was observed backlit by lightning shortly before making landfall as a tornado at Indian Mound Trail in Plantation Key, Islamorada. Large gumbo limbo tree limbs and the top of a palm tree were downed, as well as other hardwood trees. The rolling driveway gate on an adjacent residence was completely dislodged from its mounts and pushed into a trailered boat and car and an entire gutter and downspout system was removed from another residence. Numerous loose items were moved from the backyards and understory of homes onto front lawns and streets. Most of the observed damage in the Indian Waterways community were consistent with 60 to 70 mph, with possible spot values near 75 mph. The tornado crossed a patch of mangroves and undeveloped forest and reached greatest intensity at San Pedro Catholic Church where a large tree split at the trunk and an old-growth mahogany was uprooted, falling onto a portion of the structure connecting the rectory with the main church. The roof was not substantially damaged. However, several barrel tiles were removed from the peak ridges forming the hip roof pattern over the rectory, as well as from the southeast edge of the church, onto the top of the church's main entrance.Numerous large limbs were downed toward the east,with lightweight free-standing signs deposited northward cross the tornado path from right to left. Estimated wind speeds were maximized in the range of 90 to 100 mph with maximum width near 60 yards. The tornado continued toward the east-northeast, crossing U.S. Highway 1 and the Old Highway, but weakened such that only large tree limbs were downed. The tornado moved out over the ocean as a waterspout and made a second landfall near Lincoln Avenue on the far southwest portion of Tavernier's oceanside. A progressive narrowing of the damage path down to nearly 30 yards as well as a turn toward the northwest or north-northwest was observed. Impacts lessened and included damaged fences and large limbs gradually down to smaller limbs and twigs.No further impacts were observed northeast of Lowe Street. It is likely the wind speeds 55 to 65 mph were observed, weakening to below 50 mph roughly 3 blocks from the waterfront. February 18,2024 -A waterspout originating southwest of Cudjoe Bay made landfall as an EFO tornado over southern portions of Cud j oe Key. The tornado crossed U.S. Highway 1, and continued northeast as a waterspout until a second landfall as an EFO tornado over central Big Torch Key. The tornado was associated with a supercell thunderstorm with a well-defined mesocyclone moving northeast over the Lower Florida Keys. Due to the warm, humid nature and coastal geography,waterspouts occur in the Florida Keys more than anywhere else in the world. In fact,between 50 and 500 waterspouts occur per year.NCEI's storm event database changed how it reports on waterspouts and as of October 2001 ceased reporting waterspouts by county in favor of reporting by region(i.e. South Atlantic). However, for the period in which it did report by county(January 1996 through October 2001)Monroe County experienced 315 waterspout events across 184 separate days. Two of these events caused damage to property; none caused damage to crops, injuries or fatalities. Table 4.43 below lists waterspout events by date from 2000 through Sept. 2001; Table 4.43 summarizes waterspouts by location from Oct. 2001 through November 30,2024 to illustrate the frequency at which these events occur. li �iii .d ai,4 IIL...o III iii t lii ii iii*.m Strategy wi"m �&i. .: .6 SECTION 4: HAZARD IDENTIFICATION&RISK ASSESSMENT IIIIIII IIIIIII ii ��m ���� ���������������� IIIIIII' t' ������������ 1 IIIIIII�' IIIIIII' '���.IIIIIII� IIIIIII IIIIII IIIIIIP" IIIIIII IIIIIII " ,,,,,, �������������� #of Fatalities/ Property Location(s) Date Events Injuries Damage Key West I nt'I Airport 2/3/2000 3 0/0 $0 Summerland Key 3/5/2000 1 0/0 $0 Key Largo 3/18/2000 1 0/0 $0 Big Pine Key, Marathon 3/31/2000 5 0/0 $0 Key West Int'I Airport, Ramrod Key 4/8/2000 3 0/0 $0 Key West I nt'I Airport 5/7/2000 2 0/0 $0 Key West Int'I Airport 5/17/2000 3 0/0 $0 Marathon 5/23/2000 1 0/0 $0 Key West Int'I Airport, Plantation, Marathon 5/30/2000 3 0/0 $0 Key West Int'I Airport 5/31/2000 1 0/0 $0 Key West Int'I Airport, Duck Key 6/1/2000 3 0/0 $0 Key West I nt'I Airport 6/3/2000 2 0/0 $0 Key West Int'I Airport 6/4/2000 3 0/0 $0 Upper Key Largo 6/5/2000 1 0/0 $0 Key West I nt'I Airport 6/11/2000 1 0/0 $0 Key West I nt'I Airport 6/21/2000 1 0/0 $0 Big Pine Key 6/28/2000 1 0/0 $0 Key West I nt'I Airport 7/1/2000 1 0/0 $0 Marathon 7/2/2000 1 0/0 $0 Key West Int'I Airport 7/6/2000 1 0/0 $0 Marathon, Duck Key 7/16/2000 2 0/0 $0 Duck Key, Big Coppitt Island,Summerland Key 7/22/2000 3 0/0 $0 Key West Int'I Airport 7/23/2000 2 0/0 $0 Marathon 7/26/2000 1 0/0 $0 Duck Key, Key West Int'I Airport, Big Coppitt 7/28/2000 5 0/0 $0 Island Marathon 7/29/2000 1 0/0 $0 Key West I nt'I Airport 8/3/2000 1 0/0 $0 Key West I nt'I Airport 8/9/2000 2 0/0 $0 Marathon 8/11/2000 1 0/0 $0 Duck Key 8/15/2000 2 0/0 $0 Islamorada 8/16/2000 1 0/0 $0 Key West Int'I Airport 8/17/2000 2 0/0 $0 Big Pine Key 8/18/2000 1 0/0 $0 Long Key,Summerland Key, Key West, Duck Key 8/19/2000 4 0/0 $0 Key West Int'I Airport 8/21/2000 2 0/0 $0 Key West NAS 8/27/2000 1 0/0 $0 Key West I nt'I Airport 8/28/2000 1 0/0 $0 Marathon 9/9/2000 1 0/0 $0 Summerland Key 9/10/2000 1 0/0 $0 Marathon 9/11/2000 1 0/0 $0 Key West NAS 9/26/2000 1 0/0 $0 Marathon, Key West Int'I Airport 9/28/2000 3 0/0 $0 IIP �i �i .��i � � I i�l tii'i i*.m Strategy y a iii`.m U a iii. .: .6 IIC: g e"III SECTION 4: HAZARD IDENTIFICATION&RISK ASSESSMENT #of Fatalities/ Property Location(s) Date Events Injuries Damage Big Pine Key 9/30/2000 1 0/0 $0 Key West NAS, Key West I nt'I Ai rport, Ra m rod Key 10/1/2000 4 0/0 $0 Big Pine Key 10/5/2000 1 0/0 $0 Summerland Key 10/6/2000 1 0/0 $0 Key West Int'I Airport, Key West NAS, Marathon 10/8/2000 3 0/0 $0 Marathon 3/2/2001 1 0/0 $0 Islamorada 4/26/2001 1 0/0 $0 Key West, Key West I nt'I Ai rport 5/1/2001 3 0/0 $0 Key West Int'I Airport 5/20/2001 1 0/0 $0 Key West Int'I Airport 5/31/2001 1 0/0 $0 Key West Intl Airport, Big Pine Key, Ramrod Key 6/14/2001 3 0/0 $0 Big Pine Key, Big Coppit Island, Key West Int'I 6/16/2001 4 0/0 $0 Airport Big Coppit Island 6/17/2001 1 0/0 $0 Key West I nt'I Airport 7/11/2001 1 0/0 $0 Tavernier, Long Key, Duck Key 7/15/2001 3 0/0 $0 Key West I nt'I Airport 7/18/2001 1 0/0 $0 Key Largo 7/21/2001 1 0/0 $0 Key West I nt'I Airport, Key West NAS 8/10/2001 2 0/0 $0 Key West I nt'I Airport 8/11/2001 1 0/0 $0 Rock Harbor, Upper Key Largo 8/26/2001 2 0/0 $0 Key Colony Beach 9/8/2001 2 0/0 $0 Craig Key 9/12/2001 1 0/0 $0 Key West I nt'I Airport 9/18/2001 2 0/0 $0 Marathon 9/19/2001 1 0/0 $0 East Cape 9/22/2001 1 0/0 $0 Sugarloaf Key, Key West Intl Airport 9/26/2001 2 0/0 $0 Total 122 0/0 $O Source:NCEI IIIIIII� IIIIIII IIIIIII IIIIIII'"�������. � t IIIIIII �"'t' IIIIII IIIIIII IIIIIII IIIIIIP "'t t���������������� .2 4iii�� Location #of Events Fatalities/Injuries Property Damage Alligator Reef Light 23 0/0 $0 American Shoal Light 28 0/0 $0 Big Coppitt Key 64 0/0 $0 Big Pine Key 160 0/0 $200 Cosgrove Shoal Light 1 0/0 $0 Dry Tortugas 4 0/0 $0 Duck Key 37 0/0 $0 Islamorada 19 0/0 $0 Key Largo 37 0/0 $0 Key West 343 0/0 $4,000 Marathon 103 0/0 $0 Marquesas Keys 3 0/0 $0 IIP �i �i .��i � � I i�l tii'i i*.m Strategy y a iii`.m U a iii. .: .6 SECTION 4: HAZARD IDENTIFICATION&RISK ASSESSMENT Location #of Events Fatalities/Injuries Property Damage Molasses Reef Light 8 0/0 $0 Plantation Key 11 0/0 $0 Sand Key Light 26 0/0 $0 Smith Shoal Light 18 0/0 $0 Snipe Point 36 0/0 $0 Sombrero Key Light 25 0/0 $0 Summerland Key 61 0/0 $0 Tennessee Reef Light 10 0/0 $0 Total 1,017 0/0 $4,200 Source:NCEI Two of the recorded waterspouts caused$4,200 in property damage; no recorded events caused death or injury. Waterspouts have occurred in close proximity to all jurisdictions and unincorporated areas except for Layton and Key Colony Beach, however that does not mean they have not occurred. The following narrative descriptions describe the potential damage caused by waterspouts: August 5,2008—Towering cumulus cloud lines produced a couple waterspouts along the north side of the Lower Florida Keys. A short-duration waterspout was approximately one-mile northeast of Sugarloaf Key. The waterspout drifter over a vessel,producing minor damage. May 5,2019—Two waterspouts formed in succession and in association with a cloud line along the north side of Key West. The second waterspout was observed to develop within Garrison Bight outside of the Palm Drive Bridge, and drifted slowly west,reaching a dock at a sailing center. 3 catamarans were considerably damaged due to overturning while tied to the dock, causing the dock planking to twist and detach from the pilings. 3 other vessels at the same dock had minor damage with ripped covers and canopy tops. A video relayed by social media showed the width of the spray ring was only a few yards across,with the spray ring dissipating before the waterspout reached shore. No damage was observed onshore at the sailing center nor an adj acent marina. Based on historical occurrences recorded by NCEI for the 25-year period from 2000 through 2024, Monroe County averages 2.1 thunderstorm wind events per year—27 of these events caused property damage. Over this same period, 12 lightning events were reported which equates to an average of 0.48 lightning strikes per year. Additionally,the average hailstorm in Monroe County occurs in the afternoon and has a hail stone with a diameter of just over one inch. Over the 25-year period from 2000 through 2024, Monroe County experienced 7 reported hail incidents;this averages 0.28 reported incidents per year somewhere in the planning area. Based on these historical occurrences,there is a 100%chance that the County will experience severe weather each year. The probability of a damaging impacts is highly likely. ....................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................... In a 25-year period between 2000 and 2024,Monroe County experienced 32 separate tornado incidents. This correlates to over a 100 percent annual probability that the Region will experience a tornado somewhere in its boundaries. However, only one of these events was an F2; therefore,the annual probability of a significant tornado event is around 5 percent.

Probability: 4—Highly Likely C According to the National Aeronautics and Space Administration(NASA),thunderstorm events in the future are likely to become more frequent in the southeast because of weather extremes. Thunderstorm potential is measured by an index that NASA created called the Convective Available Potential Energy (CAPE) index. This measures how warm and moist the air is,which is a major contributing factor in thunderstorm/tornado formation. Between 1979 and 2021, Monroe County experienced 10-40 more days on average with CAPE at or above 1,000 J/kg, which is considered a high cape value. Figure 4.27 below shows the change in days with high potential for thunderstorms nationwide.

As the planet warms,wind shear,unlike warm,moist air, is expected to decrease. Therefore, it is difficult to predict if more supercell thunderstorm events and the tornadoes they can bring with them are more likely to occur. li �iii .b ai,4 IIL...o III iii t lii ii iii*.m Strategy J a iii`.m U a iii. .: .6 SECTION 4: HAZARD IDENTIFICATION&RISK ASSESSMENT Additionally, while supercell events are associated with tornadoes, only about 20%of supercell thunderstorms produce tornadoes. To complicate things further, no one fully understands how tornadoes are formed. Therefore,there is no identified conclusion on how climate change will impact tornadoes. The relationship between hail and climate change is also unclear, however, a 2022 study shows that climate change could increase severe and/or significant spring hailstorms within the Central U.S. (Fan, et.al, 2022). Lightning has a more direct correlation with increasing temperatures as it occurs more frequently when the temperature is hotter than when it is colder. Romps, et. al postulate that lightning will increase by 12%for every degree of rise global average air temperature. ....................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................... PEOPLE People and populations exposed to the elements are most vulnerable to severe weather. A common hazard associated with wind events is falling trees and branches. Risk of being struck by lightning is greater in open areas, at higher elevations, and on the water. Lightning can also cause cascading hazards, including power loss. Loss of power could critically impact those relying on energy to service, including those that need powered medical devices. Additionally,the ignition of fires is always a concern with lightning strikes. The availability of sheltered locations such as basements,buildings constructed using hail-resistant materials and methods, and public storm shelters, all reduce the exposure of the population. Individuals who work outdoors may face increased risk. Residents living in mobile homes are also more vulnerable to hail events due to the lack of shelter locations and the vulnerability of the housing unit to damages. The availability of sheltered locations such as basements,buildings constructed using hail-resistant materials and methods, and public storm shelters, all reduce the exposure of the population. Residents living in mobile homes are more vulnerable to hail, wind, and tornado events due to the lack of shelter locations and the vulnerability of the housing unit to damages. Overall,the housing stock in Monroe County includes 3,286 mobile home units,representing 9% of housing. Waterspouts are unlikely to cause death or injury—none were reported by NCEI. However, an exceptionally strong waterspout may lead to death or injury of individuals trapped on boat or in the water in its path. Since 2000,the NCEI records 4 injuries, and no fatalities attributed to lightning in Monroe County. NCEI records no fatalities, and no injuries attributed to wind,hail, or tornado events in Monroe County. ....................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................... PROPERTY All property, including residential and commercial buildings as well as critical facilities and infrastructure, are vulnerable to impacts from severe storms and tornadoes. Property damage caused by lightning usually occurs in one of two ways—either by direct damages through fires ignited by lightning, or by secondary impacts due to power loss. According to data collected on lightning strikes in Monroe County,recorded property damage was due to structure fires and damage to electrical systems. NCEI reports $73,000 in property damage due to lightning impacts over 25 years (2000-2024). Based on these records,the planning area experiences an annualized loss of$2,920 in property damage. The average impact from lightning per incident in Monroe County is $6,083. General damages to property from hail are direct, including destroyed windows, dented cars, and building,roof and siding damage in areas exposed to hail. Hail can also cause enough damage to cars to li �iii .d ai,4 IIL...o III iii t lii ii iii*.m Strategy J a iii`.m U a iii. .: .6 IIC: ,m..1II1. SECTION 4: HAZARD IDENTIFICATION&RISK ASSESSMENT cause them to be totaled. The level of damage is commensurate with both a material's ability to withstand hail impacts, and the size of the hailstones that are falling. Construction practices and building codes can help maximize the resistance of the structures to damage. Large amounts of hail may need to be physically cleared from roadways and sidewalks, depending on accumulation. Hail can cause other cascading impacts, including power loss. During a 25-year span between 2000 to 2024 in Monroe County,NCEI reported$250 in property damage as a direct result of hail. It should be noted that property damage due to hail is usually insured loss,with damages covered under most major comprehensive insurance plans. Because of this, hail losses are notoriously underreported by the NCEI. It is difficult to find an accurate repository of hail damages in Monroe County,thus the NCEI is still used to form a baseline. Wind events reported in NCEI for the 25-year period from 2000 through 2024 totaled$147,650 in property damage, which equates to an annualized loss of$5,906 across the planning area. Damage from tornadoes to property are both direct(what the tornado physically destroys) and indirect, which focuses on additional costs, damages and losses attributed to secondary hazards spawned by the tornado, or due to the damages caused by the tornado. Depending on the size of the tornado and its path, a tornado is capable of damaging and eventually destroying almost anything. Construction practices and building codes can help maximize the resistance of the structures to damage. Secondary impacts of tornado damage often result from damage to infrastructure. Downed power and communications transmission lines, coupled with disruptions to transportation, create difficulties in reporting and responding to emergencies. These indirect impacts of a tornado put tremendous strain on a community. In the immediate aftermath, the focus is on emergency services. Since 2000, damaging tornadoes in the County are directly responsible for nearly$5,336,700 worth of damage to property according to NCEI data. This equates to an annualized loss of$213,468. Waterspouts are unlikely to cause significant property damage unless they come on land as a tornado, in which case damage would be similar to that of a tornado. Otherwise,waterspouts may cause damage to property in the water, such as boats and other recreational items. Per NCEI,no property was damaged from waterspouts in Monroe County. ....................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................... ENVIPONMENT The main environmental impact from wind is damage to trees or crops. Wind events can also bring down power lines,which could cause a fire and result in even greater environmental impacts. Lightning may also result in the ignition of wildfires. This is part of a natural process,however, and the environment will return to its original state in time. Hail can cause extensive damage to the natural environment,pelting animals,trees and vegetation with hailstones. Melting hail can also increase both river and flash flood risk. Tornadoes can cause massive damage to the natural environment,uprooting trees and other debris within the tornado's path. This is part of a natural process,however, and the environment will return to its original state in time. Waterspouts may cause damage to marshes and wetlands.

Buildings are vulnerable to direct impact from tornadoes and from wind borne debris. Mobile homes are particularly susceptible to damage during tornadoes. Environment Potential fire ignition from lightning; hail damage to wildlife and foliage. Potential devastating impacts in storm's path. Economic Condition Lightning damage contingent on target;can severely impact/destroy critical of the Jurisdiction infrastructure and other economic drivers.Contingent on tornado's path;can severely impact/destroy critical infrastructure and other economic drivers. Public Confidence in Public confidence is not generally affected by severe weather events if the Jurisdiction's response and recovery are not timely and effective. Governance Natural hazards are often interconnected. Any given hazard may lead to, or be spurred by, another hazard —sometimes referred to as cascading disasters. Severe storms and tornadoes may be associated with floods and tropical cyclones. Development is not expected to impact the incidence of severe storms and tornadoes. As the county grows, overall asset exposure will increase,which may increase risk. Increases in mobile home and manufactured home units would cause more significant increases in vulnerability. Severe weather events are highly likely to continue occurring in Monroe County. Communities should consider examining power redundancy and surge protection solutions for critical facilities to maintain operations in the event of a power outage. Past severe storm events caused injuries to individuals outside and/or in high-risk locations during these events. Solutions might include an awareness campaign to educate the public on severe weather risk and preparedness. A robust tornado preparedness education and outreach program would benefit the community to understand risk and reduce damage; this might include the link between waterspouts and tornadoes,how to shelter from tornadoes, and damage caused from flying debris, among others. li �iii .d ai,4 IIL...o III iii t lii ii iii*.m Strategy J a iii`.m U a iii. .: .6 IIC: ,m..1II SECTION 4: HAZARD IDENTIFICATION&RISK ASSESSMENT The City of Marathon and the Unincorporated areas of the County have larger shares of mobile home units within their jurisdiction,the population living in these mobile homes are more vulnerable to tornado and wind impacts. Although the County utilizes the most recent Florida Building Code to ensure new buildings—especially critical facilities—can withstand severe winds associated with severe storms and tornadoes (as well as tropical cyclones),buildings that predate building codes are more vulnerable. A study of such buildings and potential retrofits would decrease vulnerability of these structures. The following tables summarize tornadoes and thunderstorm risk by jurisdiction. Most aspects of tornadoes and thunderstorm risk do not vary substantially by jurisdiction; however,wind and hail impacts may be greater in more highly developed areas with higher exposure in terms of both property and population density. Additionally,mobile home units are more vulnerable to wind damage. While mobile home units do not comprise a significant proportion of any jurisdictions' housing mix,mobile units make up 13%and 10% of the housing stock in unincorporated Monroe County and the City of Marathon, respectively. .......................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................

Hazard Probability Impact Spatial Warning Time Duration PRI Extent Score Tropical Cyclones Highly Likely Catastrophic Large More than 24 hrs Less than 1 week Hurricanes and tropical storms are classified as cyclones and defined as any closed circulation developing around a low-pressure center in which the winds rotate counter-clockwise in the Northern Hemisphere(or clockwise in the Southern Hemisphere) and whose diameter averages 10 to 30 miles across. A tropical cyclone refers to any such circulation that develops over tropical waters. Tropical cyclones act as a "safety-valve," limiting the continued build-up of heat and energy in tropical regions by maintaining the atmospheric heat and moisture balance between the tropics and the pole-ward latitudes. The primary damaging forces associated with these storms are high-level sustained winds,heavy precipitation, and tornadoes. The key energy source for a tropical cyclone is the release of latent heat from the condensation of warm water. Their formation requires a low-pressure disturbance,warm sea surface temperature,rotational force from the spinning of the earth, and the absence of wind shear in the lowest 50,000 feet of the atmosphere. Most hurricanes and tropical storms form in the Atlantic Ocean, Caribbean Sea, and Gulf of Mexico during the official Atlantic hurricane season,which encompasses the months of June through November. The peak of the Atlantic hurricane season is in early to mid-September and the average number of storms that reach hurricane intensity per year in the Atlantic basin is about six. While hurricanes pose the greatest threat to life and property,tropical storms and depressions also can be devastating. A tropical disturbance can grow to a more intense stage through an increase in sustained wind speeds. As an incipient hurricane develops,barometric pressure (measured in millibars or inches) at its center falls and winds increase. If the atmospheric and oceanic conditions are favorable, it can intensify into a tropical depression. When maximum sustained winds reach or exceed 39 miles per hour, the system is designated a tropical storm, given a name, and is monitored by the National Hurricane Center in Miami, Florida. When sustained winds reach or exceed 74 miles per hour the storm is deemed a hurricane. Hurricanes are given a classification based on the Saffir-Simpson Scale; this scale is reproduced in Table 4.46. The progression of a tropical disturbance is described below. Tropical Depression: A tropical cyclone with maximum sustained winds of 38 mph(33 knots) or less. Tropical Storm: A tropical cyclone with maximum sustained winds of 39 to 73 mph(34 to 63 knots). Hurricane: A tropical cyclone with maximum sustained winds of 74 mph(64 knots) or higher. In the western North Pacific,hurricanes are called typhoons; similar storms in the Indian Ocean and South Pacific Ocean are called cyclones. Major Hurricane: A tropical cyclone with maximum sustained winds of I I I mph(96 knots) or higher, corresponding to a Category 3, 4 or 5 on the Saffir-Simpson Hurricane Wind Scale. The greatest potential for loss of life related to a hurricane is from the storm surge. Storm surge is water that is pushed toward the shore by the force of the winds swirling around the storm as shown in Figure 4.28. This advancing surge combines with the normal tides to create the hurricane storm tide,which can increase the mean water level to heights impacting roads, homes and other critical infrastructure. In addition, wind driven waves are superimposed on the storm tide. This rise in water level can cause severe flooding in coastal areas,particularly when the storm tide coincides with the normal high tides. li �iii .d ai,4 IIL...o III iii t lii ii iii*.m Strategy J a iii`.m U a iii. .: .6 IIC: g,m..1II:. SECTION 4: HAZARD IDENTIFICATION&RISK ASSESSMENT The maximum potential storm surge for a location depends on several different factors. Storm surge is a very complex phenomenon because it is sensitive to the slightest changes in storm intensity, forward speed, size (radius of maximum winds-RMW), angle of approach to the coast,central pressure (minimal contribution in comparison to the wind), and the shape and characteristics of coastal features such as bays and estuaries. Other factors which can impact storm surge are the width and slope of the continental shelf and the depth of the ocean bottom. A narrow shelf, or one that drops steeply from the shoreline and subsequently produces deep water close to the shoreline, tends to produce a lower surge but higher and more powerful storm waves. A shallow slope, as is found off the coast of Monroe County,will produce a greater storm surge than a steep shelf.

Like hurricanes,nor'easters are ocean storms capable of causing substantial damage to coastal areas in the Eastern United States due to their strong winds and heavy surf.Nor'easters are named for the winds that blow in from the northeast and drive the storm up the East Coast along the Gulf Stream. They are caused by the interaction of the jet stream with horizontal temperature gradients and generally occur during the fall and winter months when moisture and cold air are plentiful. Nor'easters are known for dumping heavy amounts of rain and snow,producing hurricane-force winds, and creating high surf that causes severe beach erosion and coastal flooding. There are two main components to a nor'easter: (1) a Gulf Stream low-pressure system(counter-clockwise winds) generated off the southeastern U.S. coast, gathering warm air and moisture from the Atlantic, and pulled up the East Coast by strong northeasterly winds at the leading edge of the storm; and(2) an Arctic high-pressure system(clockwise winds)which meets the low-pressure system with cold, arctic air blowing down from Canada. When the two systems collide,the moisture and cold air produce a mix of precipitation and can produce dangerously high winds and heavy seas. As the low-pressure system deepens,the intensity of the winds and waves increases and can cause serious damage to coastal areas as the storm moves northeast.

Storm surge impacts are more limited, affecting areas along coastal and estuarine shorelines and reaching further inland depending on the height of the surge. All of Monroe County and its jurisdictions are vulnerable to hurricane and tropical storm surge. Figure 4.29 shows potential storm surge inundation for a 100-yr storm surge event and Figure 4.30 shows inundation for the 500-yr storm surge event. As shown in these maps, almost all of Monroe County and its jurisdictions are vulnerable to storm surge impacts from the 100yr storm surge event. The 500yr storm surge event inundates a similar extent but produces higher flood depths further inland. Maps of storm surge impacts by jurisdiction are available in individual jurisdictional annexes.

Wind speed is the determining factor in the Saffir-Simpson Scale(Table 4.46),which is used as a measure of hurricane intensity and rated on a scale of 1 to 5, with 5 being the most intense. Hurricane force winds can extend outward by about 35 miles from the eye of a small hurricane to more than 150 miles from the center of a large hurricane. Tropical storm force winds may extend even further, up to approximately 300 miles from the eye of a large hurricane. In general,the front right quadrant of a storm,relative to its direction of movement, is the most dangerous part of the storm. Wind speeds are highest in this area due to the additive impact of the atmospheric steering winds and the storm winds.

Categories 3,4, and 5 are classified as"maj or"hurricanes and,while hurricanes within this range comprise only 20 percent of total tropical cyclone landfalls,they account for over 70 percent of the damage in the United States.

Source:National Hurricane Center;Federal Emergency Management Agency The county is susceptible to the full force of every category of hurricane. In addition to the combined destructive forces of wind,rain, and lightning,hurricanes can cause a surge in the ocean,which also affects the severity of hurricane and tropical storm impacts. Storm surge affects areas along coastal shorelines and further inland depending on the height of the surge. Storm surge can raise the sea level as high as 25 feet or more in the strongest hurricanes. Storm surge can also cause extensive damage on the backside of a hurricane as storm surge waters are sucked back out to sea.

During the 24-year period from 2000 through 2024,NCEI records 29 hurricane and tropical storm events. The named storms associated with these events are summarized in Table 4.49. This table only represents those events reported to NCEI as a Hurricane or Tropical Storm. Where property damage estimates were broken out by type,NCEI reports only the value of wind-related damages. Hurricane Irma(2017)is reported by NCEI as a Hurricane,however there are no reported damages for Hurricane Irma despite the storm having a significant impact on the County. No official monetary figures have been reported,however Monroe County reports over 1,000 homes were destroyed and almost 3,000 suffered major damage. In total, 50 Florida counties were included in the disaster declaration and eligible for individual assistance. FEMA has approved over$1 billion individual and household program dollars across these counties.

Peak wind gusts to 64 mph were recorded at Sombrero Key Light, 61 mph at Long Key and 54 mph at Molasses Reef C-MAN stations during this convective band, along with reported wind gust to 52 mph from a spotter on Duck Key. Damage along the island chain from Marathon through Ocean Reef was limited to downed tree limbs, power lines and unreinforced signs, and almost entirely from the convective band. Beginning around 3:30 AM EST, strong gradient winds began in the Lower Keys and Dry Tortugas. Peak wind gusts of 62 mph were recorded at Sand Key C-MAN station,with gusts to 58 mph at Key West International Airport. Peak wind measurements of 46 to 52 mph were measured along the island chain from Boca Chica Key through Summerland Key. Wind damage including a few uprooted and snapped trees, large tree limbs, power lines, fences and unreinforced signs. A sailboat broke loose from moorings around 7:30 AM EST on August 13, striking a phase of a 115 kilovolt transmission line serving the lower Keys, causing a widespread power outage west of Marathon through Key West. Maximum storm surge was estimated to near 6 feet at Dry Tortugas/Garden Key. Wave action produced extensive flooding of the park grounds outside of the Fort Jefferson walls. Approximately 1000 feet of brickwork was lost on the outer moat wall,which was completely submerged at the time of high tide. Numerous finger docks and the deck of the main dock were destroyed. Scaffolding used during the Fort's multi-year renovation project was also damaged and found floating in the moat. The Dry Tortugas C- MAN station, which included instrumentation less than 15 feet above mean sea level,was also destroyed, likely from the combination of wave action and elevated tide levels. Maximum storm surge was estimated at one foot above normal at Key West. Wave action produced minor coastal flooding along the oceanfront. An estimated 11,000 visitors evacuated the Keys, causing an estimated tourism loss of 5.3 million dollars. li �iii .d ai,4 IIL...o III iii t lii ii iii*.m Strategy J a iii`.m U a iii. .: .6 IIC: 1g,m..1II SECTION 4: HAZARD IDENTIFICATION&RISK ASSESSMENT September 1,2004—As Hurricane Frances tracked from the northwest Bahamas through the central Florida peninsula, several outer rain bands crossed the Florida Keys producing short episodes of strong wind gusts. A peak wind gust of 93 mph was measured at the Sombrero Key Light C-MAN station, at an elevation of over 150 feet above mean sea level. Other notable wind gusts included 63 mph at Sand Key C-MAN and 68 mph at Molasses Reef C-MAN. Over land,peak wind gusts included 54 mph at the U.S. Coast Guard Group Key West, and 51 mph at the Key West Harbor. Stronger wind gusts were estimated along the south side of Marathon,near Flamingo Island, and in the squall that produced the extreme winds at Sombrero Key Light. These winds tore screens in porches in isolated fashion from Big Pine Key through Grassy Key and blew out plastic or vinyl panels of commercial signs in Marathon. Otherwise, damage was limited to downed tree limbs and minor power outages. As Frances passed to the north, strong northwest and west winds drove waters higher than normal along the Florida Bay shoreline up to 1 foot above normal at Vaca Key and estimated to near 2.5 feet above normal along the bayside of North Key Largo and Jewfish Creek. These tides produced minor flooding of side streets and a parking lot near Mile Marker 106 of the Overseas Highway. July 8,2005—Hurricane Dennis passed within 75 miles southwest of Key West as a category 2 hurricane. Over the Monroe County. In the Lower Keys,maximum winds were sustained at 61 mph with gusts to 74 mph at Key West and 59 mph gusting to 78 mph at Sand Key. Unofficial wind gusts to 107 mph were reported at Cudjoe Key. Maximum storm tides were estimated to 4.5 feet above mean sea level on the Atlantic shore of Key West near the International Airport. One fatality occurred aboard a vessel moored at Stock Island due to drowning. No injuries were reported. Property damage estimated at$6.8M due to wind damage mainly to roofing, electrical equipment, landscaping and mobile homes,with estimated$100K due to combined wind and rain damages to the Key West Airport. Minimum pressure reported was 998.8 mb at Sand Key. In the Middle Keys,maximum rainfall was 2.00 inches at Curry Hammock State Park, east of Marathon. Maximum winds were 74 mph gusting to 87 mph at Sombrero Key Light. Maximum storm tides were estimated at 2 to 3 feet above mean sea level,producing minor flooding under elevated homes at Marathon. Damage was estimated at $250K from wind damage to commercial signs, landscaping and electrical equipment. In the Upper Keys, the maximum rainfall was 1.55 inches at Tavernier. Maximum Storm Tides were estimated at 2 to 3 feet above mean sea level, overtopping bulkheads and producing minor street flooding. Maximum winds were recorded at 59 mph gusting to 68 mph at Carysfort Reef Light. Damage was estimated at$1 OOK mostly to landscaping and electric utility equipment. August 26,2005—Hurricane Katrina passed 40 miles north of Key West as a category one hurricane. Katrina passed 15 miles north Dry Tortugas National Park as a category 2 hurricane. Over the Monroe County Lower Keys,maximum winds were 62 mph with gusts to 77 mph at Sand Key. In the Middle Keys, Maximum winds were 67 mph with gusts to 80 mph at Sombrero Key Light, and in the Upper Keys, max winds were 61 mph with gusts to 77 mph at Molasses Reef Light. In Key West,rainfall totally 10.05 inches caused extensive street flooding and some residential flooding. At Curry Hammock State Park rainfall totaled 9.89 inches,resulting in widespread flooding. At John Pennekamp State Park in Key Largo,rainfall measured 5.94 inches. Storm tides were estimated at 2.5 feet above mean sea level at Key West, 1 foot at Molasses Reef Light, and 1.5 feet at Curry Hammock State park. Total property damage from the event in Monroe County was estimated at$6.9 million. $5 million of this damage was caused by a tornado in Marathon, and the remainder due to wind and rain damage. October 23,2005—The center of Hurricane Wilma moved northeast from the vicinity of Dry Tortugas northeast through 65 miles northwest of Key West during the night of October 23 to 24, 2005. Hurricane Wilma resulted in at least 2 injuries and at least$33 million in damages to Monroe County. In the Upper Keys, maximum winds were measured at 75 mph with gusts to 91 mph and averaged around 70 to 80 li �iii .d ai,4 IIL...o III iii t lii ii iii*.m Strategy wi"m �&i. .: .6 IIC: ,m..1II 8 SECTION 4: HAZARD IDENTIFICATION&RISK ASSESSMENT mph. In the Middle Keys,maximum winds measured 87 mph with gusts to 105 mph at Sombrero Key Light and averaged an estimated 80 to 90 mph. In the Lower Keys, maximum winds were measured at 71 mph with gusts to 83 mph before instrumentation failed. Peak wind gusts of 123 mph at Cudjoe Key and 133 mph at Dry Tortugas National Park were recorded by spotters and park personnel. Overall,winds averaged 80 to 90 mph across the Lower Keys. Monroe County experienced general Category 1 Saffir Simpson damage from wind. Rainfall associated with the storm was fairly light,ranging from 1.5 inches at Pennekamp State Park to 2.39 inches at Duck Key. The most destructive aspect of Hurricane Wilma was the storm surge. In the Upper Keys, Wilma primarily produced one storm tide along the bayside ranging from 4 to 5 feet above sea level with the worst in Lower Matecumbe Key. North of Key Largo,U.S. Route 1 was temporarily flooded at least 3 inches. In the Middle Keys,Wilma caused two separate storm tides. The first was 3 feet above mean sea level along the south shore of Marathon. The second tide was up to 9.5 feet above mean sea level along the north shore of Marathon. At one point during the storm,the City of Marathon was completely under water. Most homes and businesses sustained damage by flooding of 2 to 4 feet with severe electrical, drywall and mold-related damages. Wilma also caused two separate storm tides in the Lower Keys. The first was 4.5 feet above mean sea level along the south shore of Key West. The second ranged from near 6 feet above mean sea level at Key West to 8.5 feet along the north shore of Big Coppitt Key, Cudjoe Key, and Big Pine Key. About 60 percent of Key West was under water, and nearly 12000 vehicles were flooded. Most homes sustained damage by flooding of 2 to 3 feet with severe electrical, drywall and mold-related damages. August 17,2008—Tropical Storm Fay moved north from Cuba, through the Florida Straits, and passed north through the Lower Florida Keys. Fay affected mainland Monroe when the storm made landfall on August 19th near Cape Romano. Across the Upper Florida Keys, storm total rainfall ranged from 3.42 inches at Plantation Key to 4.38 inches at Islamorada. The highest sustained wind in the Upper Florida Keys was 37 mph with a peak gust of 53 mph recorded at Upper Matecumbe Key.A peak gust of 60 mph was recorded at the Islamorada Fire Station. Across the Middle Florida Keys, storm total rainfall ranged from 2.45 inches at Long Key to 7.27 inches at Marathon. The highest sustained wind in the Middle Florida Keys of 49 mph with a peak gust of 56 mph was recorded at Long Key. In the Lower Keys, storm total rainfall ranged from 3.35 inches at Key West International Airport to 7.05 inches at Ramrod Key. The highest sustained wind of 38 mph with a peak gust of 51 mph was recorded at Key West International Airport. A peak gust of 54 mph was recorded at Cudjoe Key. In mainland Monroe County,maximum sustained winds were estimated to be around 60mph at landfall and increased to around 65 mph. The Keys also experienced minor coastal storm tides during this event. In the Upper Keys such tides peaked at 2.5 feet above mean sea level along the south shore of Lower Matecumbe Key, equating to a storm surge less than one foot above astronomical tide levels. Similarly coastal storm tide peaked at 2.5 feet above mean sea level along the south shore of Marathon and in the Lower Keys. One direct serious injury due to wind-blown debris occurred in Marathon,but no fatalities were reported. 25,000 people, mainly visitors and non-residents of the Florida Keys,were evacuated. Countywide Tourism losses were estimated at 8 to 10 million dollars. Damage and preparedness costs to government facilities and infrastructure totaled 2.8 million dollars,with about one million dollars due to coastal flooding damage to roads, and 200,000 dollars due to erosion. Approximately 120,000 dollars damaged occurred due to wind. 2 tornadoes occurred in the Lower Keys,with no structural damage reported. Total damage due to the tornadoes was approximately one thousand dollars. September 9-10, 2017—Hurricane Irma made landfall over the Lower Florida Keys as a category 4 hurricane on the Saffir-Simpson Scale,with the eye crossing directly over Cudjoe Key. Due to the large radius of hurricane-force winds, destructive hurricane-force winds and storm surge impacted all of the Florida Keys. Extensive damage to residences,businesses, electric,water and communications utilities resulted. When Irma made landfall over Cudjoe Key, it had maximum sustained winds near 130 mph. li �iii .d ai,4 IIL...o III iii t lii ii iii*.m Strategy wi"m �&i. .: .6 IIC:)�g,m..1II SECTION 4: HAZARD IDENTIFICATION&RISK ASSESSMENT The highest sustained winds in the Lower Florida Keys were measured at 70 mph at the Key West Harbor,with a peak measured gust at 120 mph at the Key Deer National Wildlife Refuge and a private residence on Big Pine Key. Storm survey evidence estimated the highest 3-second wind gusts on Big Pine Key and Scout Key, at 150 to 160 mph. Rainfall totals of 6 to 12 inches were measured at available rain gauges,with a maximum of 12.54 inches at the Key Deer Wildlife Refuge on Big Pine Key. Maximum storm surge in the Lower Florida Keys was measured at 5 to 8 feet from Sugarloaf Key through Duck Keys,with total water height reaching a maximum of 5 to 6 feet above ground level in eastern Big Pine Key, and wave wash marks up to 20 feet above mean high water along Long Beach Road on the south side of Big Pine Key. In the Middle Florida Keys, storm surge estimates of 5 to 8 feet were evident from Marathon and Key Colony Beach, Grassy Key, and Duck Key. Storm surge values of 3 to 5 feet were observed from Conch Key through Long Key and Layton. Total water height ranged from around 4 to 5 feet above ground level along the western edge of Marathon and Key Colony Beach to about 2 feet above ground level in Layton. In the Upper Keys, storm surge of 3 to 4 feet was observed throughout Islamorada through Ocean Reef, as well as along Barnes Sound near Manatee Bay. Total water heights were generally 2 to 4 feet above ground level. In the Upper Keys, flooding of oceanside residences and businesses up to 2 feet occurred. In the Middle Keys, numerous mobile homes were destroyed in Marathon as the storm surge pushed them off their foundations. In the Lower Keys,major damage to mobile homes and marinas was observed along the oceanside, especially from Ramrod Key,through Big Pine Key,through Ohio Key. The eastbound lanes of U.S. Highway 1 were washed out just east of the Bahia Honda State Park entrance. Many residences and businesses were flooded at the maximum surge. More than 1,300 vessels were damaged or destroyed, requiring removal from the coastal waters. Differing reports detail injuries and fatalities attributed to the storm differently.NCEI reports a total of 10 fatalities—4 of which were directly attributed to the storm—and 40 direct injuries. Direct reports from Monroe County and the incorporated jurisdictions list no deaths(Layton, Key Colony Beach, Islamorada), 3 deaths (Key West), and 13 deaths (Monroe). Key West also reported 6 injuries. The list below summarizes other damages reported by the County and incorporated jurisdictions: — 85%of housing stock impacted,more than 4,000 homes destroyed or damaged(Monroe County); — Commercial lobster industry lost$3.7 million in traps, estimated economic loss of$38.9 million; — 80%of businesses suffered extended losses; — Tourism industry($2.7 billion) suffered long term impacts; — Extended power outages (11 days in most areas,up to 20 days to restore entire grid), some water system impacts; — Airports, schools,re-entry, and ports closed for as little as 7 and up to 15 days; — $25 million in property damages and$12 million in infrastructure damage, $16 million in economic impacts.

November 7,2020—Tropical Storm Eta passed northwest through the middle Florida Keys. Primary impacts from wind occurred as result of a rain band which drifted very slowly north through the Upper Florida Keys. Peak wind gusts were between 50 to 60 mph, downing trees and large tree limbs,utility lines, and a billboard. One residence was destroyed by a fallen tree resulting in one minor injury. Two other residential structures were significantly damaged,with three inaccessible due to blocked streets. About 20 separate power outages affected about 1,000 customers, mostly in Key Largo. li �iii .d ai,4 IIL...o III iii t lii ii iii*.m Strategy wi"m �&i. .: .6 IIC:)I g,m III60 SECTION 4: HAZARD IDENTIFICATION&RISK ASSESSMENT Storm Surge flooding was generally in the 1.5-to-2.5-foot range,producing significant street flooding in oceanside Key Largo neighborhoods. The northbound right-of-way was damaged including major erosion, loss of riprap, and about 3,000 feet of fencing along northbound U.S. Highway 1 along the west end of Barnes Sound and Manatee Bay. Minor overwash occurred in the middle Florida Keys at Key Colony Beach, along with yard and dock flooding along the Florida Bay side of Marathon. Widespread rainfall of 3.5 to over 8 inches was measured throughout the Keys,with the highest totals in Key Largo. Damages were estimated near$500K due to homes damaged by falling trees and tree limbs, as well as utility damage. Storm Surge damage was estimated around$1 OOK due to wave action to the U.S Highway 1 right-of-way. July 5,2021 —Tropical Storm Elsa brought numerous rain bands through the Lower and Middle Florida Keys, with strong tropical-storm-force wind gusts measured near Key West. Maximum winds over the Florida Keys of Monroe County were recorded at 52 mph with gusts to 70 mph at Key West. Wind impacts were confined to damage to trees and utility lines,mostly in Key West proper. A few power distribution circuits were out in the city of Key West due to fallen trees and tree limbs. Total customers impacted were estimated around 3,500 in the Lower Keys. No storm surge was recorded in the Florida Keys,however the onshore southerly winds raised water levels just below 1.0 foot above normal at Key West closer to low astronomical tide. Moderate oceanside beach erosion occurred at Key West along with overwash from heavy wave action. Rainfall estimates of 7.5 inches resulted in brief but significant street flooding in Key West. September 27,2022—Hurricane Ian moved north from far western Cuba into the western Straits of Florida. As Ian moved north over the Dry Tortugas and into the southeastern Gulf of Mexico, tropical storm force winds and damaging storm surge occurred across the Florida Keys. A secondary but lesser storm surge occurred along the Gulf of Mexico and Florida Bay side of the Lower and Middle Keys after Major Hurricane Ian moved inland the west coast of Florida, and well after tropical storm force winds had subsided. Sustained tropical storm force winds occurred in the Lower Florida Keys and were measured in the 45 to 60 mph range. Peak gusts of 79 mph at the Key West International Airport, 68 mph at the Naval Air Station Key West Boca Chica Field, and 75 mph at an electric substation on Big Coppitt Key. Wind damage occurred in the form of scattered large tree limbs downed,with isolated uprooted or snapped trees. Scattered fences were downed in the city of Key West,with isolated building damage. Total power outages peaked near 10,000 customers in the Lower Florida Keys,representing approximately one-third of the Keys Energy service area. August 29,2023—Hurricane Idalia produced tropical storm-force wind gusts occurred in squalls which passed mainly through portions of the Lower Florida Keys. The maximum winds and rainfall occurred with the passage of one strong rainband which resulted in isolated fallen trees and tree limbs, isolated power outages primarily affecting a street block or two at a time. The combination of an approaching spring tide and strong southerly winds sustained just below tropical storm force resulted in storm tides ranging from 1.0 to 2.5 feet above MHHW along the oceanside. Moderate to heavy ocean wave overwash and street flooding within a few oceanside neighborhoods on the southwest portion of Key West occurred within a few hours of high tide. August 3,2024—Hurricane Debby caused tropical storm-force wind gusts with rain bands extending throughout the Straits of Florida and Florida Keys. Sustained tropical storm force winds occurred over the coastal waters mainly from along the Lower Florida Keys west of the Seven Mile Bridge through Dry Tortugas. The tropical-storm force wind gusts resulted in fallen large tree limbs and isolated power outages primarily affecting a street block or a multi-unit residential complex at a time. The combination high tide and strong southerly winds sustained just below tropical storm force resulted in storm tides up to an estimated 1.8 feet above MHHWIalong the oceanside of the Lower Florida Keys,but lower water li �iii .d ai,4 IIL...o III iii t lii ii iii*.m .uira egy wi"m �&i. .: .6 SECTION 4: HAZARD IDENTIFICATION&RISK ASSESSMENT levels were measured at gauges in the lee along the Gulf of Mexico and Florida Bay side of the Florida Keys. Moderate to heavy ocean wave overwash resulted in temporary flooding on oceanfront low elevation streets in Key West. In combination with brief heavy rainfall from the rain bands, a section of State Road A 1 A in Key West was closed due to having little or no drainage in a construction zone. September 25,2024—Hurricane Helene moved northeast across the eastern Gulf of Mexico, strengthening to category 2 strength. Widespread lower-end tropical storm force winds overspread the Florida Keys and its adjacent coastal waters producing isolated large tree limb and utility line damage. Coastal flooding in lowest elevation parts of the Florida Keys occurred initially with storm surge around 1.5 feet MHHW along the oceanside of the Florida Keys accompanied by heavy wave action with coastal flooding across eastern Florida Bay. October 9,2024—Hurricane Milton moved northeast across the eastern Gulf of Mexico, gradually weakening from category 5 to category 4 strength while passing, at the closest approach, about 180 statue miles to the northwest of Key West. Widespread lower-end tropical storm force winds overspread the Lower Florida Keys and its adjacent coastal waters producing isolated large tree limb and utility line damage. Coastal flooding in lowest elevation parts of the Florida Keys occurred initially with storm surge around 1.5 feet MHHW along the oceanside of the Florida Keys accompanied by heavy wave action on, with storm surge in Gulfside and Florida Bayside. The highest storm surge values near 3.0 feet above MHHW occurred in Key Largo along Blackwater Sound. One tornado was observed as a waterspout moved ashore the far southwest portion of Key West. November 6,2024—The center of Hurricane Rafael passed 125 miles southwest of Key West as a category 2 hurricane. Lower-end tropical storm force winds impacted portions of the Lower Florida Keys producing isolated small tree limb damage. Minor coastal flooding and Atlantic-side wave overwash occurred in Key West. Brief street flooding occurred in Key West due to brief,heavy squalls from outer rainbands mainly impacted the Lower Florida Keys. Minor coastal flooding also occurred in Stock Island, and Boca Chica Key with water levels reaching near 1.2 feet above mean higher high water(MHHW). Minor street flooding occurred along with a temporary closure of State Road A 1 A(South Roosevelt Boulevard) in Key West within an ongoing construction zone. C Florida has over 8,000 miles of coastline that often gets hit by direct storms. The state is very vulnerable to the impacts of hurricanes and tropical storms as detailed in this section. Substantial hurricane damage is typically most likely to be expected in the coastal counties of the state; however,hurricane and tropical storm-force winds have significantly impacted areas far inland. Figure 4.32 shows, for any location, the chance of a hurricane or tropical storm affecting the area sometime during the Atlantic hurricane season. The figure was created by the National Oceanic and Atmospheric Administration's(NOAA) Hurricane Research Division, using data from 1944 to 1999. The figure shows the number of times a storm or hurricane was located within approximately 100 miles (165 kilometers) of a given spot in the Atlantic basin. Per this data,there has historically been approximately a 42%-48% chance of a hurricane occurring in Monroe County in any given year. li �iii .d ai,4 IIL...o III iii t lii ii iii*.m Strategy wi"m �&i. .: .6 IIC: I g,m SECTION 4: HAZARD IDENTIFICATION&RISK ASSESSMENT uuuuuuu� uuiil°Illpw � uuuuuuu wuo�pwu� umul i� i wuo �������� ������ IIIIIII ° IIII Illlllk III11111141IIIIIIIIIIII IIIIIII 1111114IIIIIII IIIIIII IIIIIII IIIIIIIIIIIIII t aIIIIIII 1111114 IIIIIII 11111141IIIIIIII IIIIIII 5O 12 6 1 �I 24 m m 40 m m m m k� m lu m 3 5N / .30N �u� �I 6N'' m m f� u�l r 4i,,, w �I� 3 G 4 I,; f��� 18 20 m 4-2 4 m uu ICI + 1 111111111� �I 1$ 1 1I w1 ��ull '!I VVVVVuuuuuu �� u I I�u'ul',lul ' 4' ��III I'll' 4 �7- 1 5 6 1 5� 18 r)4 �5R :56 4-r) 48 54 EO Source:National Oceanic and Atmospheric Administration,Hurricane Research Division In the 24-year period from 2000 through 2024,28 hurricanes and tropical storm have impacted Monroe County, which equates to over 100 percent annual probability of hurricane winds impacting the planning area in any given year. This probability does not account for impacts from hurricane rains or storm surge, which may also be severe. The probability of a hurricane or tropical storm impacting Monroe County is highly likely. Probability: 4—Highly Likely �i......... C................... ............... �MA` 11100 Monroe County's coastal location makes it a prime target for hurricane landfalls and changing climate and weather conditions may increase the number and frequency of future hurricane events. Hurricanes and other coastal storms may result in increased flooding, injuries,deaths, and extreme property loss. According to the US Government Accountability Office,national storm losses from changing frequency and intensity of storms is projected to increase anywhere from$4-6 billion in the near future. According to NOAA,weather extremes will likely cause more frequent, stronger storms in the future due to rising surface temperatures.NOAA models predict that while there may be less frequent, low-category storm events (Tropical Storms, Category 1 Hurricanes),there will be more, high-category storm events (Category 4 and 5 Hurricanes)in the future.

Monroe County Emergency Management employs Alert!Monroe mass notification system to share emergency notifications with residents quickly. Messages are pushed out to residents on preferred primary and secondary contact paths, including cell phone, SMS/text,home phone, or email. Residents listed in public phonebook databases are automatically subscribed,but the County encourages residents to self-register cell phones and emails. The system can provide alerts to all users in the County as well as tailored information to specific geographical areas and neighborhoods. ....................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................... EVACUATION Per Monroe County `s 2022 Comprehensive Emergency Management Plan,the County is the most vulnerable area in the United States to the threat of tropical cyclones. The low-lying islands that make up the Florida Keys are connected by 42 bridges and one single thoroughfare, the Overseas Highway or U.S. 1. For these reasons, an evacuation plan is especially necessary. The county has five main evacuation obj ectives: — Return of non-residents to the mainland; — Promote early voluntary evacuation; — Relocate vulnerable populations; — Selective evacuation of specific zones; and — Phased, general evacuation to mainland. Various factors are considered when the Director of Emergency Management decides to implement a mandatory phased evacuation and how far in advance to do so. Historic trends illustrate base clearance times for evacuating the keys ranges from 24 to 48 hours, with a minimum of 12 hours and a maximum of 30-plus hours. Another factor to consider is the time of year based on population changes due to tourism. For Tropical Storms and Category 1 and 2 hurricanes, all visitors will be asked to evacuate out of the County, Special Needs residents will be transported to an in-county shelter or out of the County to the Monroe County shelter at Florida International University, and mobile home residents will either be sheltered in-county or asked to evacuate. For a category 3 storm or greater, a phased evacuation is implemented, including all visitors, hospitals, special needs residents, and the general population. The evacuation timeline is as follows: Approximately 48 hours in advance of tropical storm winds,mandatory evacuation is initiated for non- residents, visitors,recreational vehicles,travel trailers, live-aboards, and military personnel. Approximately 36 hours in advance of tropical storm winds,mandatory evacuation is initiated for mobile home residents, special needs residents, and hospital and nursing home patients. Approximately 24 to 30 hours in advance of tropical storm winds,mandatory phased evacuation of permanent residents is initiated. The phased evacuation is accomplished through the determination of zones. The five zones, as seen in Figure 4.33, allow for selective evacuation,phased evacuation, and in-county shelter options. The five zones are as follows: li �iii .d ai,4 IIL...o III iii t lii ii iii*.m Strategy J a iii`.m U a iii. .: .6 SECTION 4: HAZARD IDENTIFICATION&RISK ASSESSMENT Zone 1: City of Key West, including Stock Island and Key Haven,to the Boca Chica Bridge (U.S. 1 Mile Marker(MM) 1 —MM 6) Zone 2: Boca Chica Bridge to the west edge of the 7-Mile Bridge(MM6-MM40) Zone 3: West end of the 7-Mile Bridge to the end of Long Key Bridge (MM40-MM63) Zone 4: West end of the Long Key Bridge to the confluence of CR 905 and 905A(3-way stop) (MM63- MM106) Zone 5: CR 905A to and including Ocean Reef(MM 106-MM 126.5) Although mainland Monroe is not heavily populated,National Parks Services employees and their families who reside there, and the Native American population,which occupies their trial land would evacuate to hurricane rated hotels,motels, or to the facility designated for hurricane shelter at Flamingo Park. Private residents would evacuate to Miami-Dade shelters. The sequence of the evacuation by zone may vary by individual storms. This evacuation plan applies to all municipalities to ensure safety of all county residents. li �iii .d ai,4 IIL...o III iii t lii ii iii*.m Strategy J a iii`.m U a iii. .: .6 IIC::) ,m�g "III 3" (ID .................. ............. ..............................................................................................................................................................................................................................................................................................................................................................................................................

PEOPLE Children, elderly, individuals with disabilities, and others who may have difficulty evacuating are especially vulnerable to harm from hurricanes. For those who are unable to evacuate for medical reasons, there should be provision to take care of special-needs patients and those in hospitals and nursing homes. Many of these patients are either oxygen-dependent, insulin-dependent, or in need of intensive medical care. There is a need to provide ongoing treatment for these vulnerable citizens, either on the coast or by air evacuation to upland hospitals. The stress from disasters such as a hurricane can result in immediate and long-term physical and emotional health problems among victims. Individuals in mobile homes are more vulnerable to hurricane winds, especially if their unit does not have tie downs and other wind safety measures. This is further evidenced by Monroe County's emphasis on evacuating manufactured home residents. Overall,there are 4,696 mobile home units in Monroe County, making up almost 9 percent of the County's total housing stock. Over 12 percent of the housing stock in Marathon is mobile home units. Additionally,there are over 3,300 mobile home units in unincorporated Monroe County, again making up close to 13 percent of the total housing stock. These communities may face more severe impacts from hurricane events as a result.

PROPERTY General damages to property are both direct(what the winds associated with hurricanes physically destroy) and indirect,which focuses on additional costs, damages and losses attributed to secondary hazards spawned by the hurricane, or due to the damages caused by the storm. Depending on the size and strength of the hurricane, associated winds are capable of damaging and eventually destroying almost anything. Construction practices and building codes can help maximize structures' resistance to damage. Secondary impacts of damage due to hurricane winds often result from damage to infrastructure. Downed power and communications transmission lines, coupled with disruptions to transportation, create difficulties in reporting and responding to emergencies. These impacts of a hurricane put tremendous strain on a community. In the immediate aftermath of a hurricane,the focus is on emergency services. Two Hazus level 1 analyses were used to determine hurricane risk. The first simulated the wind losses experienced during Hurricane Irma in 2017. The second was based on probabilistic parameters for the 50- year, 100-year, and 500-year return periods. This analysis produced estimates of the likelihood of varying levels of damage as well as building-related economic losses.Note that Hazus only assesses hurricane wind and does not account for any other hazards associated with hurricane. Table 4.53 provides the likelihood of damage at varying levels of severity by occupancy type expected for a storm of magnitude similar to Hurricane Irma(2017). Table 4.54 provides the likelihood of damage at varying levels of severity by occupancy type during three probabilistic hurricane events-a 50-year, 100- year, and 500-year return period. During an event of magnitude similar to Hurricane Irma's,more than 44%of buildings in the County are estimated to potentially sustain damages. 30%, 80%, and 72% of buildings in the county are likely to sustain damage during the 50-year, 100-year, and 500-year return period events, respectively. uuuu 1 uuuuuu uuu°II plVl iu uuu umu ����� ulllll �� ����� 11� 1'10 �������VI ulllllq I 1111 I�11 11111 mllo uu lm�v lm�v 11 11111 lm°1w ��������������� IIIIIII IIIIIII IIIIIII IIIIIII (IIIIIIIIIII IIIIIII IIIIIII IIIIIII. ����� I I IIIIIII um uIIII 1 IIIIIIIIIII IIIIIII III ��1 IIIIIII um� IIIIIII � pullll m�� III.IIIIIII IIIIIII .IIIIIII IIIIIII IIIIIII Ilullllu�.

This equates to a loss ratio of 9.6 percent. Estimated losses for a 50-year, 100-year, and 500-year probabilistic wind event total $3,541,879,320, $5,670,594,530, and $10,660,649,210,respectively; this equates to a loss ratio of 20 percent for a 50-year event, 31 percent for a 100-year event, and 59 percent for a 500-year return period event. These loss ratios are determined by dividing total estimated losses (from Table 4.55 and Table 4.56)by the total value at risk in the county (from Table 4.53 and Table 4.54). Estimates from a Hazus level 1 analysis use 2018 ACS 1-year estimates; actual losses or loss ratios may be higher depending on development changes in recent years. FEMA considers a loss ratio of 10 percent or more to be an indicator that a community will have significant difficulty recovering from an event. The 50-year, 100-year, or 500-year event will cause significant difficulties for recovery. Damages from an actual hurricane event would likely also involve storm surge and flood impacts that would raise the damage total. Therefore, even a 100-year hurricane event may cause more serious damages that what is reported here from Hazus. Table 4.57 below summarizes the number of buildings impacted by 100yr and 500 yr storm surge events. Buildings are counted only once for the lowest category storm they will be affected by; it can be assumed that a building affected by storm surge associated a 100yr event will also be impacted by a 500yr storm surge event. °°° Illlllhlllllll °°° °°°°°° IIIIIII IIIIIII IIIIIII IIIIIII IIIIIII IIIIIII Illlllh IIIIIII IIIIIII IIIIIII IIIIIIIIIIIIII°° IIIIII IIIIIII IIIIIIIo IIIIIII°°° 1111114 IIIIIII um mm uuuum Occupancy Estimated Structure Value Estimated Total Value Building Count Content Value 100yr Event 489524 $2394559250,646 $131,869,6819211 $37,324,931,858 Agriculture 1 $267,735 $267,735 $535,470 Commercial 4,221 $3,160,987,416 $3,160,987,416 $6,321,974,832 Education 59 $39,541,055 $39,541,055 $79,082,110 Government 1,490 $697,950,350 $697,950,350 $1,395,900,700 Industrial 456 $157,650,870 $236,476,305 $394,127,176 Religious 128 $70,063,480 $70,063,480 $140,126,961 Residential 42,169 $19,328,789,740 $9,664,394,870 $28,993,184,609 500yr Event 19689 $7509158,690 $512,936,550 $1,263,0959240 Agriculture 0 $0 $0 $0 Commercial 325 $189,452,819 $189,452,819 $378,905,638 Education 2 $2,320,805 $2,320,805 $4,641,610 Government 43 $71,480,016 $71,480,016 $142,960,033 Industrial 7 $2,453,522 $3,680,283 $6,133,805 Religious 8 $7,553,727 $7,553,727 $15,107,453 Residential 1,304 $476,897,801 $238,448,900 $715,346,701 Total 50,213 $24,205,409,336 $14,382,617,762 $38,588,027,098 IIP �i �i .��i � � I i�l tii'i i*.m Strategy y a iii`.m U a iii. .: .6 IIC: i I e..1117' SECTION 4: HAZARD IDENTIFICATION&RISK ASSESSMENT Due to the limitations of a Hazus level 1 analysis, damage estimates for critical facilities could not be calculated. Critical infrastructure, including the Keys' energy transmission pipelines, could also be impacted by hurricane winds. Given equal vulnerability to hurricane winds across all of Monroe County, all critical facilities are considered to be at risk. Certain buildings may perform better than others based on their age and construction, among other factors. Depending on their locations, critical facilities may also be at risk to storm surge flooding. Table 4.58 below provides counts for the number of critical facilities at risk to the 100yr and 500yr storm surge event. Based on these results, 94 percent of the assessed facilities are exposed to one storm surge.

ECONOMY The disruption of the local economy is an anticipated consequence of hurricanes that directly effects Monroe County. Beyond debris generation and destruction of property that require monetary inputs to haul away and rebuild, hurricanes and tropical storms have other significant impacts on the Monroe County economy. The primary industries in the Keys—retail, service,tourism, and fishing—are all likely to be negatively impacted by a hurricane or tropical storm. Any event causing visitors to stay away would result in losses to local businesses as well as tax revenue for the local economy. Any event that causes a power outage or damage to U.S. 1 is likely to have such impacts on tourism. Further, it has been noted that the perception of damage that lingers after recovery period may continue to keep visitors away. Additionally, the fishing industry would suffer from loss of power(for ice production), loss of communication infrastructure, and damage to U.S. 1 (transport to the mainland. Hazus reports the business interruption losses for a Hurricane Irma equivalent as well as a 50-, 100-, and 500-year probabilistic hurricane wind event as follows: uu°i poop u m �� i mum p IIIIIII��� lllllll 4� ����������������IIIIIIk������1� IIIIIII IIIIIII°°���������: IIIIIII IIIIIII° �t IIIIIII IIIIIII�1111114� tlllllll IIIIIII° IIIIIII����������� � 1111114���������1111111 IIIIIII�IIIIIII�IIIIIII IIIIIII°° �Illlllk�������������� Business Interruption Residential Commercial Industrial Others Total Hurricane Irma Equivalent Income $3,436,900 $89,815,800 $1,572,120 $826,360 $95,651,180 Relocation $90,981,700 $34,906,000 $7,226,720 $10,545,290 $143,659,710 Rental Income $51,899,210 $22,355,240 $1,624,670 $1,621,630 $77,500,760 Wage $8,096,770 $77,502,020 $2,602,340 $6,334,190 $94,535,330 Total $15494149580 $22495799060 $1390259860 $199327,470 $411,346,970 50-year Hurricane Event Income $21,878,560 $117,184,980 $1,536,580 $1,016,790 $141,616,910 Relocation $155,300,440 $44,346,270 $5,532,750 $12,802,390 $217,981,850 Rental Income $96,823,590 $29,766,300 $1,478,970 $1,287,130 $129,355,990 Wage $51,522,110 $109,657,080 $2,543,240 $6,617,800 $170,340,230 Total $32595249690 $30099549630 $1190919540 $21,724,110 $659,294,980 100-year Hurricane Event Income $23,784,240 $285,505,320 $4,342,860 $1,374,520 $315,006,930 Relocation $259,353,820 $99,128,960 $17,273,860 $29,934,620 $405,691,240 Rental Income $165,268,280 $66,216,650 $4,502,330 $4,649,470 $240,636,730 Wage $56,030,010 $251,959,670 $7,196,040 $10,160,310 $325,346,030 Total $504,436,340 $702,810,600 $33,315,080 $46,1189920 $1,286,6809940 500-year Hurricane Event Income $64,787,890 $522,325,220 $7,601,500 $3,061,180 $597,775,790 Relocation $384,432,210 $164,118,790 $24,645,670 $50,306,670 $623,503,340 Rental Income $279,299,610 $115,319,720 $7,201,580 $8,435,510 $410,256,430 Wage $152,626,150 $461,891,130 $12,626,530 $22,257,810 $649,401,630 Total $881,145,870 $1,263,654,860 $52,075,290 $84,061,180 $2,280,937,190 Source:Hazus .......................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................

SECTION 4: HAZARD IDENTIFICATION&RISK ASSESSMENT changes in habitat and food availability caused by high winds and intense rainfall. Endangered species can be dramatically impacted. Forests can be completely defoliated by strong winds. Although South Florida ecosystems have adapted to episodic massive disturbances such as hurricanes,the growth of urban environments have altered the natural ecology and thus the ability for those ecosystems to respond and recover from these events. In the Keys,the predominantly coastal floodplain serves different functions than a traditional floodplain and responds to disturbances differently. Although hurricanes are necessary and natural occurrences for the maintenance of the unique natural environment, they can still cause significant damage. The mangroves, which provide protective buffers from wind and storm surge,marshes,pine rockland forests,hardwood hammocks, and reef systems are all important parts of this unique natural environment. Many of these features have suffered significant damage during prior hurricanes. During Hurricane Andrew,many of the mangroves in Everglades National park were damaged; delayed mortality meant this continued well past the end of the storm, a phenomenon that has been observed after prior storms as well. After Hurricane Wilma, storm surge was especially detrimental to the pine rockland forest throughout the Florida Keys National Wildlife Refuge.Additionally,virtually all pines on Cudj oe Key were killed along with high mortality of young and mature trees on Big Pine, Sugarloaf, and Little Torch Keys. .......................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................

Specific foods can be taken away as high winds will often strip fruits,seeds and berries from bushes and trees.Secondary impacts may occur;for example, high winds and debris may result in damage to an above-ground fuel tank, resulting in a significant chemical spill. Economic Condition of Local economy and finances adversely affected, possibly for an extended the Jurisdiction period of time,depending on damages. Intangible impacts, including business interruption and additional living expenses, may also occur. Public Confidence in Public confidence may be affected by a major storm event requiring the Jurisdiction's substantial response and long-term recovery effort. Governance Natural hazards are,more often than not, interconnected. Any given hazard may lead to, or be spurred by, another hazard—sometimes referred to as cascading disasters. Tropical Cyclones may be associated with: Storm Surge, Flood, Coastal Erosion, Sea Level Rise, and Tornado. While increased development will not impact the incidence of hurricane wind, it will lead to more exposure, which in turn may increase risk. This is especially true for mobile home development,which is more at risk to wind. In Monroe County,mobile home development is limited by its ordinances— particularly limiting new mobile homes to designated mobile home parks and dictate the height at which these homes may be elevated. Like flooding, increased development will likely lead to increased impervious surfaces,which could potentially increase the impacts and patterns of storm surge. Because the County relies almost entirely on the Overseas Highway for evacuation purposes, any future development will impact evacuation time. The County has implemented a Rate of Growth Ordinance for both residential and non-residential development to keep evacuation time under 24 hours. The evacuation of the Florida Keys occurs entirely on US Highway 1 —if this highway becomes impassable due to rain or other roadblocks, evacuation will become increasingly difficult. The County and participating jurisdictions must continue to prioritize vulnerable communities,including keeping the special needs registry used during evacuations up to date. There is continued concern that these groups may not respond to evacuation orders; transportation to the mainland is also a concern. The County and jurisdictions rely on shelters on the mainland during evacuation times—availability of shelter space within and outside of the County is a concern as the County and region grow. Communities with greater shares of mobile home units—such as Marathon and Unincorporated Monroe County—are more vulnerable to hurricane winds. Visitors to Monroe County during the summer months may burden evacuation times. The population of Monroe County increases during the late autumn and winter; late in hurricane season, this increase in population may overburden the shelter capacity. li �iii .d ai,4 IIL...o III iii t lii ii iii*.m Strategy J a iii`.m U a iii. .: .6 IIC: ,m..1II 7' .

Due to its coastal geography, the entire county is susceptible to the impacts of hurricanes,tropical storms, and the associated storm surges and flooding. While hurricanes have the possibility of being catastrophic across all jurisdictions, certain areas have higher vulnerability. Impacts may be greater in more highly developed areas with greater amounts of impervious surface and higher exposure in terms of both property and population density. Areas with more mobile homes are also more vulnerable to damage,while areas with higher property values have greater overall exposure and potential for damages.

WILDFIRE 1 Hazard Probability Impact Spatial Warning Time Duration PRI Extent Score Wildfire Likely Limited Small Less than 6 hrs Less than 1 week 2. A wildfire is an uncontained fire that spreads through the environment. Wildfires can consume large areas, including infrastructure,property, and resources. When massive fires, or conflagrations, develop near populated areas, evacuations possibly ensue.Not only do the flames impact the environment,but the massive volumes of smoke spread by certain atmospheric conditions also impact the health of nearby populations. There are three general types of fire spread that are recognized. — Ground fires—burn organic matter in the soil beneath surface litter and are sustained by glowing combustion. — Surface fires—spread with a flaming front and burn leaf litter, fallen branches and other fuels located at ground level. — Crown fires—burn through the top layer of foliage on a tree,known as the canopy or crown fires. Crown fires, the most intense type of fire and often the most difficult to contain, need strong winds, steep slopes and a heavy fuel load to continue burning. Fuels to wildfires are subject to a variety of ignition sources,both natural and human caused. Generally, wildfires are started by humans, either through arson or carelessness. Fire intensity is controlled by both short-term weather conditions and longer-term vegetation conditions. During intense fires,understory vegetation, such as leaves, small branches, and other organic materials that accumulate on the ground, can become additional fuel for the fire. The most explosive conditions occur when dry,gusty winds blow across dry vegetation. Historically, fire starts have been contained quickly with minimal loss to property and structures. Weather plays a major role in the birth, growth and death of a wildfire. Weather conditions favorable to wildfire include drought,which increases flammability of surface fuels, and winds,which aid a wildfire `s progress. The combination of wind,temperature, and humidity affects how fast wildland fires can spread. Rapid response can contain wildfires and limit their threat to property. In support of forecasting for fire weather,the National Weather Service Fire Weather Program emerged. This service is provided to federal and state land management agencies for the prevention, suppression, and management of forest and rangeland fires. Monroe County experiences a variety of wildfire conditions found in the Keetch-Byram Drought Index, which is described in Table 4.62. The Keetch-Byram Drought Index(KBDI) for February 26, 2025, is shown in Figure 4.34. The KBDI for Monroe County and the surrounding areas at this time was between 200 and 400. °°° Illlllh IIIIIII 4, IIIIIII t°Illlllh IIIIIII IIIIIII IIIIIII IIIIIII°'IIIIIII IIIIIII °i IIIIIII IIIIIII IIIIIII Illilll IIIIIII IIIIIII°' IIIIIII IIIIIII IIIIIII' t lllilll IIIIIIISys°t IIIIIII KBDI Description 0-200 Soil and fuel moisture are high.

The Functional WUI is described as the classification of the land near buildings into zones that describe the wildfire risk mitigation activities appropriate for each zone. Buildings used in producing the li �iii .d ai,4 IIL...o III iii t lii ii iii*.m Strategy wi"m �&i. .: .6 g e..1II 1Y.7 IIY SECTION 4: HAZARD IDENTIFICATION&RISK ASSESSMENT Functional WUI are defined as greater than 40 square meters. There are five Functional WUI categories recognized. There are five Functional WUI categories recognized. — Direct Exposure: Burnable land cover within 75 m of a building. Buildings in this zone are exposed to ignition from convective and radiative heat from a wildfire, embers, and adjacent burning structures/outbuildings. — Indirect Exposure: Nonburnable land cover within 75 m of a building and less than 1530 m from a 500-ha contiguous block of wildland fuel. Buildings in this zone are exposed to ignition from embers and/or adjacent burning structures — Critical Fireshed: The burnable land cover from which a wildfire can reach a significant number of buildings within a single burning period. — Little-to-no Exposure: Nonburnable land cover within 75 m of a building and more than 1530 m from a 500-ha contiguous block of wildland fuel. Buildings in this zone are relatively safe from ember ignition and building-to-building spread. — Sources of Ember Load to Buildings: Burnable land cover more than 75 m from a building that produces embers capable of reaching nearby buildings. Ember production is a function of fire type and intensity; ember travel is a function of wind speed and direction. Ember modeling is based on fire modeling based on gridded historical climatology. The Southern Wildfire Risk Assessment(SWRA) estimates that 15 percent of Monroe County's population lives within the critical fire shed and 1 percent live in direct exposure to the Functional WUI. The expansion of residential development from urban centers out into rural landscapes increases the potential for wildland fire threat to public safety and the potential for damage to forest resources and dependent industries. Population growth within the WLJI substantially increases the risk of wildfire.

Fire Intensity ratings identify where significant fuel hazards and dangerous fire behavior potential exist based on fuels, topography,and a weighted average of four percentile weather categories. The Fire Intensity Scale consists of five classes, as defined by Southern Wildfire Risk Assessment and is shown in Table 4.64. Table 4.65 and Figure 4.36 show the potential fire intensity within the WLTI across Monroe County. Detailed maps of fire intensity by jurisdiction are provided in each community's annex. Table 4.64-Fire Intensity Scale Class Description 1,Very Low Very small,discontinuous flames,usually less than 1 foot in length;very low rate of spread;no spotting. Fires are typically easy to suppress by firefighters with basic training and non-specialized equipment. 2,Low Small flames,usually less than two feet long;small amount of very short-range spotting possible. Fires are easy to suppress by trained firefighters with protective equipment and specialized tools. 3,Moderate Flames up to 8 feet in length;short-range spotting is possible. Trained firefighters will find these fires difficult to suppress without support from aircraft or engines, but dozer and plows are generally effective. Increasing potential for harm or damage to life and property. 49 High Large Flames,up to 30 feet in length;short-range spotting common; medium range spotting possible. Direct attack by trained firefighters,engines,and dozers is generally ineffective,indirect attack may be effective.

SECTION 4: HAZARD IDENTIFICATION&RISK ASSESSMENT Per the Southern Wildfire Risk Assessment, 31 percent of Monroe County is non-burnable.Note that this includes areas of the County that are open water. A significant portion of the land area, approximately 29 percent, of Monroe County may experience a Class 4 or higher Fire Intensity, which poses significant harm or damage to life and property. However,the areas with greatest potential fire intensity are largely outside the WUI-including Everglades National Park. Potential fire intensity is also high on Big Pine Key. Approximately 2 percent of the county may experience Class 3 or 3.5 Fire Intensity,which has potential for harm to life and property but is easier to suppress with dozer and plows. The remainder of the burnable area(approximately 38 percent)would face a Class 1 or Class 2 Fire Intensity,which are easily suppressed. Florida participates in the national Ready, Set, Go! program which helps prepare first responders to best address wildfires when they occur. This program is also used as outreach to help citizens understand their risk and how to be prepared. As part of this program,the State produced a Wildfire Mitigation Plan. Monroe County has addressed fire hazards in their County Emergency Management Plan; however, it is considered a minimal threat. Impact: 2-Limited NCEI does not report any records of wildfire in Monroe County within the 25-year period from 2000 through 2024. However,the Florida Department of Agriculture and Consumer Services maintains records of acreage burned and number of fires within the State of Florida. According to this department, there were 167 fires between January 1 St, 2000 and December 31 St, 2024, averaging 6.7 fires per year. However, these fires burned only 186.8 acres in total, averaging 1.12 acres per fire.

Thunderstruck Fire: In 2007,the Thunderstruck Fire burned 7 acres on Big Pine Key, affecting vacant property adjacent to residential and commercial structures. The Florida Division of Forestry brought in resources from Miami to assist in controlling the fire. The U.S. Fish and Wildlife Service provided helicopter water drops to help control the fire spread. During this event, firefighters from several stations worked in yards of homes and several businesses to prevent damage. Flame lengths exceeded thirty feet, and nearly all the vegetation was killed as a result of severity and intensity. Big Pine Key Brush Fire: The Big Pine Key Brush Fire began around 2pm on April 22, 2018 in a wooded area on Big Pine Key. Due to strong winds and dry conditions,the fire spread quickly and burned a total of 72 acres. Due to a quick,unified response from 10 different agencies, including Monroe County Emergency Services,Florida Forest Service,the U.S. Fish and Wildlife Service and others from Key West to Georgia, only one home and an associated detached garage were destroyed, and 30 other homes were saved in the burn area. There were no reported injuries or loss of life. With help from 1.7 inches of rain recorded at the Big Pine Key Forestry site on April 27th,which reduced heat in the fire's interior,the fire was completely contained and put out by April 29th. Overall, 93 percent of the pine rock lands on Big Pine Key were left unburned. The State of Florida uses this Active Wildfires Dashboard to communicate to others where the currently burning wildfires are located. At the time this data is collected,there are 3 active wildfires in the state of Florida The region experienced prolonged periods of moderate to severe drought in 2000 to 2001, 2007 to 2008, 2009,20111 2015,and 2018. These periods of drought may explain some of the annual variation in fires and acreage burned. The Southern Wildfire Risk Assessment provides a Burn Probability analysis which signifies the likelihood of a wildfire burning a specific location within a set time frame - commonly represented as the chance of burning during one calendar year or wildfire season. According to the SWRA, Burn Probability can be expressed as a fraction(ex. 0.005) or odds (1-in-200) and is based on fire behavior modeling across thousands of simulations of possible fire seasons. In each simulation, factors contributing to the probability of a fire occurring, including weather and ignition likelihood are varied based on patterns derived from observations in recent decades. It is not predictive and does not reflect any currently forecasted weather or fire danger conditions. Burn Probability does not say anything about the intensity of a fire if it occurs. The Burn Probability for Monroe County is presented in Table 4.67 and illustrated in Figure 4.37.Note that approximately 30 percent of the land area in the County does not have a Burn IIP �i �i .��i � � I i�l tii i*m Strategy y a iii`.m U a iii. .: .6 SECTION 4: HAZARD IDENTIFICATION&RISK ASSESSMENT Probability class assigned to it.

The areas of higher burn probability are located on the mainland of Monroe County in Everglades National Park. The Keys themselves have a relatively low burn probability. The probability of wildfire across the county is considered likely, defined as between a 10%and 100%annual chance of occurrence. The mainland (Everglades National Park),and Big Pine Key are areas that have historically seen wildfire and area likely to experience wildfire again due to their higher burn probability and potential fire intensity.

As global temperatures rise,the likelihood of more frequent and prolonged periods of extreme heat increase,which can dry out vegetation, soil, and organic matter,making them more susceptible to ignition. Additionally,the intensification of drought conditions means that water availability for plants and ecosystems could become increasingly scarce, leading to a reduction in the moisture content of vegetation, soils, and decomposing organic material, all of which play a critical tole in wildfire dynamics. Moreover,the unpredictability of climate change means that both seasons could become more extreme in their respective ways, amplifying the impacts on wildfire behavior.

PEOP LE Wildfire pose significant risks to human life and health, causing fatalities, injuries, and long-term health complications such as respiratory issues due to smoke inhalation. To mitigate these dangers,it is crucial to implement comprehensive procedures for rapid warning and evacuation. Developing reliable early warning systems that utilize satellite monitoring, drones, and weather forecasts can help alert communities to emerging threats. Local authorities should communicate through various channels, including SMS alerts, social media and community radio, to ensure that messages everyone effectively. Effective communication and coordination among local fire departments, law enforcement, and emergency management agencies are vital for an orderly and safe evacuation process. After evacuations, providing support affected individuals and families is crucial,including access to medical care,mental health services, and resources for rebuilding. Establishing community networks can further assist residents during recovery. ....................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................... PROPERTY Wildfire can lead to sustainable direct property losses, impacting buildings,vehicles, landscaped areas, agricultural lands, and livestock. The destruction of homes and businesses not only results in financial losses but can also displace families and disrupt communities. One effective approach to increasing fire resistance is the use of fire-rated materials in construction such as non-combustible roofing, siding, and decks, as well as tempered glass windows that can withstand high temperatures. Additionally,building codes that require certain fire safety measures, such as proper ventilation and firebreaks, can further protect properties from encroaching flames. Landscaping practices are another vital element in reducing vulnerability to wildfires. By incorporating fire-resistant plants and creating defensible space around properties typically a buffer zone that extends at least 30 feet from structures homeowners can limit the flammability of their surroundings. Techniques such as maintaining a green lawn,using gravel or stone mulch, and keeping trees trimmed can minimize the potential for fire to spread to buildings. ....................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................... ENVIRONMENT Wildfires have the potential to cause extensive damage to forest and forage resources, significantly affecting both natural habitats and agricultural land. When a wildfire sweeps through a forest, it can obliterate vast areas of vegetation, leading to loss of trees, shrubs, and underbrush that provide habitat for wildlife. This destruction disrupts ecosystems, displacing animal species and impacting their food sources. li �iii .d ai,4 IIL...o III iii t lii ii iii*.m Strategy J a iii`.m U a iii. .: .6 IIC:) g e"I06 SECTION 4: HAZARD IDENTIFICATION&RISK ASSESSMENT Additionally, wildfires can severely damage agricultural crops on private land. The intense heat and smoke can harm plants,leading to reduced yields or complete crop failure. This not only affects farmers economically but can also have broader implications for local and regional food supplies. The destruction of crops can lead to higher food prices and food scarcity, impacting communities that depend on these resources. The recovery process can vary based on factors such as the severity of the fire,the type of ecosystem affected, and climate conditions. In many cases,wildfires can lead to the growth of new, diverse plant communities that enhance soil quality and increase habitat complexity. Additionally,the ash left behind can provide essential nutrients that stimulate the growth of new vegetation. .......................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................

Exposure to wildfire smoke can cause serious health problems within a community,including asthma attacks and pneumonia,and can worsen chronic heart and lung diseases.Vulnerable populations include children,the elderly, people with respiratory problems or with heart disease. Even healthy citizens may experience minor symptoms, such as sore throats and itchy eyes. Responders Public and firefighter safety is the first priority in all wildland fire management activities. Wildfires are a real threat to the health and safety of the emergency services. Most fire-fighters in rural areas are'retained'.This means that they are part-time and can be called away from their normal work to attend to fires. Continuity of Wildfire events can result in a loss of power which may impact operations. Operations(including Downed trees, power lines and damaged road conditions may prevent access Continued Delivery of to critical facilities and/or emergency equipment. Services) Property, Facilities and Wildfires frequently damage community infrastructure, including roadways, Infrastructure communication networks and facilities, power lines,and water distribution systems. Restoring basic services is critical and a top priority. Efforts to restore roadways include the costs of maintenance and damage assessment teams, field data collection,and replacement or repair costs. Direct impacts to municipal water supply may occur through contamination of ash and debris during the fire,destruction of aboveground distribution lines,and soil erosion or debris deposits into waterways after the fire. Utilities and communications repairs are also necessary for equipment damaged by a fire.This includes power lines,transformers,cell phone towers,and phone lines. Environment Wildfires cause damage to the natural environment, killing vegetation and animals.The risk of floods and debris flows increases after wildfires due to the exposure of bare ground and the loss of vegetation. In addition,the secondary effects of wildfires, including erosion,landslides, introduction of invasive species,and changes in water quality,are often more disastrous than the fire itself.

Wildfires,and extreme fire danger, may reduce recreation and tourism in and near the fires. If aesthetics are impaired, local property values can decline. Extensive fire damage to trees can significantly alter the timber supply, both through a short-term surplus from timber salvage and a longer- term decline while the trees regrow.Water supplies can be degraded by post-fire erosion and stream sedimentation. Public Confidence in Wildfire events may cause issues with public confidence because they have the Jurisdiction's very visible impacts on the community. Public confidence in the jurisdiction's Governance governance may be influenced by actions taken pre-disaster to mitigate and prepare for impacts,including the amount of public education provided; efforts to provide warning to residents; response actions;and speed and effectiveness of recovery. The following table summarizes wildfire hazard risk by jurisdiction. Wildfire warning time and duration do not vary by jurisdiction. Spatial extent ratings were estimated based on the percentage of direct exposure within the WUI;jurisdictions with approximately 10%to 50% of direct exposure were assigned a spatial extent rating of 3. Impact ratings were based on fire intensity data from SWRA. Jurisdictions with significant clusters of moderate to high fire intensity were assigned a rating of 3; all other jurisdictions were assigned a rating of 2. Probability ratings were determined based on burn probability data from SWRA. Only the unincorporated areas of the county have any areas with moderate to high burn probability and was thus given a probability rating of 3. All other jurisdictions were assigned a probability of 2.

Hazard Probability Impact Spatial Warning Time Duration PRI Extent Score Cyber Attack Possible Limited Small Less than 6 hrs More than 1 24 week The State of Florida Hazard Mitigation Plan defines a cyber incident as "an incident involving computers, networks, and information or services that affect daily operations of critical infrastructure,"noting that a Cyber Incident can be either malicious or stem from a system glitch or human error. The SHMP defines a cyber attack, then, as a cyber incident with malicious intent. Cyber-attacks use malicious code to alter computer operations or data. The vulnerability of computer systems to attacks is a growing concern as people and institutions become more dependent upon networked technologies. The Federal Bureau of Investigation(FBI)reports that"cyber intrusions are becoming more commonplace,more dangerous, and more sophisticated,"with implications for private- and public-sector networks. There are many types of cyber-attacks. Among the most common is a direct denial of service, or DDoS attack. This is when a server or website will be queried or pinged rapidly with information requests, overloading the system and causing it to crash. Malware, or malicious software, can cause numerous problems once on a computer or network, from taking control of users' machines to discreetly sending out confidential information. Ransomware is a specific type of malware that blocks access to digital tiles and demands a payment to release them. Hospitals, school districts, state and local governments, law enforcement agencies,businesses, and even individuals can be targeted by ransomware. Cyber spying or espionage is the act of illicitly obtaining intellectual property, government secrets, or other confidential digital information, and often is associated with attacks carried out by professional agents working on behalf of a foreign government or corporation. According to cybersecurity firm Symantec, in 2016 "...the world of cyber espionage experienced a notable shift towards more overt activity, designed to destabilize and disrupt targeted organizations and countries." Major data breaches -when hackers gain access to large amounts of personal, sensitive, or confidential information-have become increasingly common. The Symantec report says more than seven billion identities have been exposed in data breaches over the last eight years. In addition to networked systems, data breaches can occur due to the mishandling of external drives, as has been the case with losses of some state employee data. Cyber crime can refer to any of the above incidents when motivated primarily by financial gain or other criminal intent. The most severe type of attack is cyber terrorism, which aims to disrupt or damage systems in order to cause fear, injury, and loss to advance a political agenda. The State of Florida has several cyber security mechanisms. The Florida Computer Crime Center(FC3) conducts cyber investigations,training,research, and prevention, and developed the Florida Infrastructure Protection Center(FIPC). The FIPC was developed to anticipate,prevent,react to, and recover from acts of terrorism, sabotage, and cyber Grim. One component of the FIPC is the Computer Incident Response Team(CIRT)which is on-call to respond to critical cyber incidents in Florida. The Agency for State Technology developed a Statewide Strategic Information Technology Security Plan to protect the li �iii .d ai,4 IIL...o III iii t lii ii iii*.m Strategy wi"m �&i. .: .6 IIC:) g e"I09 SECTION 4: HAZARD IDENTIFICATION&RISK ASSESSMENT confidentiality, integrity, and availability of the state's IT resources. FDEM also has a Cyber Incident Plan. Warning Time: 4—Less than six hours Duration: 4—More than one week Cyber disruption events can occur and/or impact virtually any location in the state where computing devices are used. Incidents may involve a single location or multiple geographic areas.A disruption can have far-reaching effects beyond the location of the targeted system; disruptions that occur far outside the County can still impact people,businesses, and institutions within the County. Spatial Extent: 2—Small The extent or magnitude/severity of a Cyber disruption event is variable depending on the nature of the event. A disruption affecting a small, isolated system could impact only a few functions/processes. Disruptions of large, integrated systems could impact many functions/processes, as well as many individuals that rely on those systems. There is no universally accepted scale to quantify the severity of cyber-attacks. The strength of a DDoS attack is sometimes explained in terms of a data transmission rate. One of the largest DDoS disruptions ever, which brought down some of the internet's most popular sites on October 21, 2016,peaked at 1.2 terabytes per second. Data breaches are often described in terms of the number of records or identities exposed. The Florida State Hazard Mitigation Plan defines three levels of cyber-attacks: Unstructured: attacks with little to no organization and no significant funding. Such attacks are usually carried out by amateurs using pre-made tools to attack well known system flaws. These attacks are most common,but are also easily spotted by network security Structured: attacks with more organization and planning and decent financial backing. These attacks have specific targets and intend to disrupt operations to a specific organization or sector. The impacts might range from minimal to significant. Highly Structured: attacks involve extensive organization,planning, and funding. Attackers conduct reconnaissance and use multiple attacks to achieve their goals. Impact: 2—Limited The Privacy Rights Clearinghouse, a nonprofit organization based in San Diego,maintains an estimated timeline of 17,552 unique data breaches, of which at least 7,130 were acts of computer hacking,in the United States from 2005-2023. The database lists 700 total data breaches, including 330 hacking events in Florida,totaling over 19.6 million records breached since 2005. Similarly, some residents in the region were likely affected by national and international data breaches. Media reports indicate an uptick in cyber-attacks across the state. SecuLore also provides its own database of Cyber Attacks across the country via local media outlets, broken down by state and infrastructure affected. Based on local media outlets,Monroe County has seen the following four attacks: li �iii .d ai,4 IIL...o III iii t lii ii iii*.m Strategy J a iii`.m U a iii. .: .6 IIC:)I g,m"III 9 SECTION 4: HAZARD IDENTIFICATION&RISK ASSESSMENT September 2018 (Education): The Monroe County School District was forced to shut down its computer system for almost a week due to a cyber attack. The incident was first noticed by an employee who contacted the IT department. The event was eventually escalated to the District's internet security provider who advised securing and shutting down the entire system. The culprit was a ransomware called "GandCrab."No data was threatened and no demands for ransom were actually made, as the district had appropriately backed up its data. In order to reopen the system,the District had to rebuild each server individually. The system was first up and running again after three days,but had to be shut down only an hour later. It was then slowly restarted,but was delayed due to a cable and internet outage. May through November 2018 (Education): The Florida Keys Community College (FKCC)reported of suspicious activity,potentially phishing, on an employee's email account. An investigation into this suspicious activity revealed an unknown individual had access certain college employees' email accounts. The press release noted that some combination of name, address, date of birth, social security number, passport information,medical information,usernames, and passwords may have been accessible to the hackers. In response,the college notified potentially impacted employees and individuals, and offered those individuals 12 months of free identity protection services. FKCC also implemented increased security measures for account access such as multi-factor authentication. March 2020 (Local Government): Beginning in March of 2020, a software attack crippled the City of Marathon's communication system, including email, internet, and broadcast capabilities. The system was ransomed, and the attack and subsequent recovery took over 4 months. The City had to update and de- encrypt most computers. Costs associated include insurance policies, specialist and IT assistance, and time costs of systems being down. August through September 2020 (Local Government): For the two weeks between August 28'through September 16th, 2020,the computers in the Key West City Hall were inaccessible due to a suspected virus. These impacts also impacted the Key West Police Department. The networks at City Hall were shutdown voluntarily when the virus was initially discovered to allow IT workers to identify the problem and rebuild the servers. During this week,police officers were writing police reports on paper—with a backlog to be uploaded when the servers returned. Additionally, any requests for existing reports were difficult to fulfil because the reports would have to physically be located in the building. Community members could still pay parking tickets and apply for building permits,but this could not be done online and had to be done by mail or in person. Cyber attacks occur daily,but most have negligible impacts at the local or county level. The possibility of a larger disruption affecting systems within the county is a constant threat,but it is difficult to quantify the exact probability due to such highly variable factors as the type of attack and intent of the attacker. Minor attacks against business and government systems have become a commonplace occurrence but are usually stopped with minimal impact. Similarly, data breaches impacting the information of residents of Monroe County are almost certain to happen in coming years. Major attacks or breaches specifically targeting systems in the county are less likely but cannot be ruled out. Probability: 2—Possible S As discussed above,the impacts from a cyber attack vary greatly depending on the nature, severity, and success of the attack. li �iii .d ai,4 IIL...o III iii t lii ii iii*.m Strategy wi"m �&i. .: .6 SECTION 4: HAZARD IDENTIFICATION&RISK ASSESSMENT .......................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................

Radiological incidents related to transportation are described as an incident resulting in a release of radioactive material during transportation. Transportation of radioactive materials through Florida over the interstate highway system is considered a radiological hazard. The transportation of radioactive material by any means of transport is licensed and regulated by the federal government. As a rule,there are two categories of radioactive materials that are shipped over the interstate highways: — Low level waste consists primarily of materials that have been contaminated by low level radioactive substances but pose no serious threat except through long-term exposure. These materials are shipped in sealed drums within placarded trailers. The danger to the public is no more than a wide array of other hazardous materials. — High level waste,usually in the form of spent fuel from nuclear power plants, is transported in specially constructed casks that are built to withstand a direct hit from a locomotive. Radiological emergencies at nuclear power plants are divided into classifications. Table 4.70 shows these classifications, as well as descriptions of each. °°°' Illlllh�lllllll Il111111."°°°°°' Illilll Illilli IIIIIII IIIIIIIIIIIIIIIIIIIlIIIIII IIIIIII°°° IIIIIII IIIIIII s lllilll°flllilll ibillilll IIIIIII���� 1111114���� ��IIIIIII Emergency Classification Description Events are in progress or have occurred which indicate a potential Notification of Unusual degradation of the level of safety of the plant or indicate a security threat to Event(NOUE) facility protection has been initiated.

Warning Time: 4—Less than 6 hours Duration: 4—More than one week Turkey Point Nuclear Generating Station, located in the south of Miami-Dade County and northeast of the planning area, is a twin reactor nuclear power station. It has three currently operating units including two 802-megawatt units (units 3 and 4) and one 1,1 50-megawatt unit(unit 5). There are two retired 404- megawatt units (units 1 and 2) still on-site. Commercial operation began in 1967 and the most recent unit was completed in 2007. Units 3 and 4 are pressurized water reactors and unit 5 is a combined-cycle gas- fired unit. As the sixth largest power plant in the United States and third largest in Florida,it serves all of southern Florida. The plant is operated with a very high level of security. This is the location from which the most catastrophic nuclear accident might occur and will be the focal point of the nuclear analysis in this plan. In December of 2019,units 3 and 4 at Turkey Point Nuclear Generating Station was granted the world's first 80-year operating license. The Nuclear Regulatory Commission defines two emergency planning zones around nuclear plants: — Emergency Planning Zone (EPZ)—The EPZ is a 10-mile radius around nuclear facilities. It is also known as the Plume Exposure Pathway. Areas located within this zone are at highest risk of exposure to or inhalation of radioactive materials. Within this zone,the primary concern is exposure to and inhalation of radioactive contamination. Predetermined action plans within the EPZ are designed to avoid or reduce dose from such exposure. This is the designated evacuation radius recommended by the Nuclear Regulatory Commission and residents within this zone would be expected to evacuate in the event of an emergency. Other actions such as sheltering and the use of potassium-iodide must be taken to avoid or reduce exposure in the event of a nuclear incident. — Ingestion Pathway Zone(IPZ)—The IPZ is delineated by a 50-mile radius around nuclear facilities as defined by the federal government. Also known as the Ingestion Exposure Pathway, the IPZ has been designated to mitigate contamination in the human food chain resulting from a radiological accident at a nuclear power facility. Contamination to fresh produce, water supplies, and other food produce may occur when radionuclides are deposited on surfaces. Figure 4.3 8 shows the location of Turkey Point Nuclear Generating Station and the approximate 10-mile Emergency Planning Zone(EPZ)buffer and 50-mile Ingestion Pathway Zone(IPZ) around the plant. The northeastern-most tip of the Florida Keys,just north of Key Largo, falls within the 10-mile EPZ. Much of mainland Monroe and the Keys north of Islamorada fall within the IPZ.

May 8, 1974—During a routine test, it was discovered that two of the three Emergency Feedwater pumps which served unit 3 failed due to overtightened packing. The third pump also failed but was caused by a malfunction in the turbine. These failures,had they not been found and corrected, could have led to a nuclear disaster if other failures had occurred simultaneously. August 24, 1992—Category 5 Hurricane Andrew hit Turkey Point causing damage to many systems. The fire protection systems were partly disabled, two raw water tanks were destroyed, a third was drained, and the smokestack on unit I cracked. Offsite power was lost so onsite generators had to be operated for numerous days. February 26,2008—The loss of offsite power prompted both reactors to shut down which lead to a widespread power outage affecting 700,000 customers and a total of 2.5 million people. The originating event was an overheated voltage switch that caught fire in a substation 23 miles away from Turkey Point. Power was restored within 5 hours of the blackout. Large commercial locations such as Walt Disney World, Orlando International Airport, and Miami International Airport were affected. March 18,2017—An electrical fault happened in unit 3 causing the loss of a safety system and a reactor trip. This fault caused an arc flash which minorly burned one plant worker. All other safety systems were operational so there was no threat to the community or environment.

On August 17th,plant operators manually shut down the reactor as a response to rising steam generator water levels. On August 19th, an instrument sensed higher-than-expected neutron activity in the reactor core, causing the plant's protection system to automatically shut down the reactor during startup. On August 20th, a reactor was once again manually shut down after the loss of a steam generator feed water pump. These three shutdowns in a short time frame prompted a Nuclear Regulatory Commission(NRC)inspection. ( Radiological hazards are highly unpredictable.Nuclear reactors present the possibility of catastrophic damages,yet the industry is highly regulated and historical precedence suggests an incident is unlikely. Probability: I — Unlikely While climate change is not projected to have any direct impact on a potential nuclear power plant incident, the low-lying coastal location of the Turkey Point Nuclear Generating Station in Miami-Dade County means this plant is particularly susceptible to the impacts of sea level rise and increased storm surge. The plant won federal approval to continue operating through at least 2053. By the end of the plant's current license, Miami-Dade is planning for just under 2 feet of SLR while Turkey Point is planning for 0.5 to just over 1 foot of Sea Level Rise. The threat of increasing incidences of flood and higher storm surges could increase the likelihood of an event at Turkey Point. ....................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................... PEOPLE People within the 10-mile EPZ are at risk of direct exposure to radioactive material. People within the 50- mile EPZ are at risk of exposure through ingestion of contaminated food and water. Low levels of radiation are not considered harmful,but a high exposure to radiation can cause serious illness or death. Beyond those in the EPZ and IPZ,the entirety of Monroe County is potentially at risk because of operations at the Turkey Point Nuclear Generating Station. Turkey Point relies on a one-of-its-kind 5,900- acre cooling canal system—rather than the more commonly used cooling towers. Millions of gallons of saltwater have seeped from these canals into the Biscayne aquifer beneath the canals; an underground saltwater plume has spread more than 10.6 miles inland. As the majority of Monroe County's drinking water is supplied by the Biscayne Aquifer, continued,unresolved saltwater intrusion threatens the health of all residents. ....................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................... O PERTY A radiological incident could cause severe damage to the power station itself but would not cause direct property damage outside the station, especially with the distance between the reactor and the planning area.

Continuity of Operations An incident at the nuclear plant could interrupt power generation and (including Continued cause power shortages. Regular operations would likely be affected by the Delivery of Services) response effort an event would require. Property, Facilities and The plant itself could be damaged by a radiological incident. Nearby Infrastructure property and facilities could be affected by contamination. Water supplies,food crops,and livestock within 50 miles of the nuclear Environment plant could be contaminated by radioactive material in the event of a major incident. Economic Condition of The local economy could be affected if a radiological incident caused the Jurisdiction contamination of nearby areas. Property values and economic activity could decline as a result. Public Confidence in the A radiological incident would likely cause severe loss of public confidence Jurisdiction's Governance given that the hazard is human-caused and highly regulated. Public confidence can also be affected by false alarms. Natural hazards are often interconnected. Any given hazard may lead to, or be spurred by, another hazard —sometimes referred to as cascading disasters. Radiological Incidents, although not natural,may be associated with certain natural hazards, including flood,tropical cyclone,tornado, and sea level rise. Northeastern Monroe County is most at risk to the impacts of a radiological incident at the Turkey Point Nuclear Facility. An effective education and outreach program about the impacts of radiation within the EPZ would help reduce vulnerability to those living within this zone. The Village of Islamorada and areas north in Unincorporated Monroe County are within the Ingestion Pathway Zone,meaning food grown in this area or water will be impacted in the event of a nuclear emergency. Community members here are only at risk if they ingest impacted food/drinks and should be educated as such. The continued utilization of cooling canals at Turkey Point threatens further saltwater intrusion into the Biscayne Aquifer and in turn threatens the predominant drinking water source for the entire county. The following table summarizes radiological incident risk by jurisdiction. Risk is not expected to change substantially between jurisdictions,however jurisdictions overlapping with the Ingestion Pathway Zone were given an impact rating of critical. li �iii .d ai,4 IIL...o III iii t lii ii iii*.m Strategy J a iii`.m U a iii. .: .6 IIC:)Eige.11119 SECTION 4: HAZARD IDENTIFICATION&RISK ASSESSMENT Jurisdiction Probability Impact Spatial WarningDuration Score Priority Extent Time Islamorada 1 3 3 4 4 2.6 M Key Colony 1 2 3 4 4 2.3 M Beach Key West 1 2 3 4 4 2.3 M Layton 1 2 3 4 4 2.3 M Marathon 1 2 3 4 4 2.3 M Unincorporated 1 3 3 4 4 2.6 M Monroe County IIP �i �i .��i � � I i�l tii'i i*.m Strategy y a iii`.m U a iii. .: .6 IIC)a g e 2,1-1' SECTION 4: HAZARD IDENTIFICATION&RISK ASSESSMENT ....................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................... i,, .....................

This ranking carries a high threat to the general population and/or built environment. The potential for damage is widespread. Moderate Risk—Moderate potential impact. This ranking carries a moderate threat level to the general population and/or built environment. Here the potential damage is more isolated and less costly than a more widespread disaster. Low Risk—Minimal potential impact. The occurrence and potential cost of damage to life and property is minimal.

As in any planning process, it is important to try to establish which goals, objectives, and actions are feasible,based on an understanding of the organizational capacity of those agencies or departments tasked with their implementation. A capability assessment helps to determine which mitigation actions are practical and likely to be implemented over time given a local government's planning and regulatory framework, level of administrative and technical support, fiscal resources, and current political climate. A capability assessment has two primary components: 1) an inventory of a local jurisdiction's relevant plans, ordinances, and programs already in place; and 2) an analysis of its capacity to carry them out. Careful examination of local capabilities will detect any existing gaps, shortfalls, or weaknesses with ongoing government activities that could hinder proposed mitigation activities and possibly exacerbate community hazard vulnerability. The capability assessment also highlights the positive mitigation measures already in place or being implemented at the local government level,which should continue to be supported and enhanced through future mitigation efforts. The capability assessment completed for Monroe County serves as a critical planning step toward developing an effective mitigation strategy.

Other indicators included information related to fiscal, administrative, and technical capabilities, such as access to local budgetary and personnel resources for mitigation purposes, and existing education and outreach programs that can be used to promote mitigation. In addition to requesting LMSWG input,the planning team re-examined data from the 2020 plan and conducted a review of plans,policies, and ordinances in order to identify changes in capability over the past five years. The previous plan's capability assessment was developed using feedback from the LMSWG through a detailed Local Capability Self-Assessment worksheet.

It includes emergency response and mitigation planning, comprehensive land use planning, and transportation planning. Regulatory capability also includes the enforcement of zoning or subdivision ordinances and building codes that regulate how land is developed and structures are built, as well as protecting environmental,historic, and cultural resources in the community. Although some conflicts can arise,these planning initiatives generally present significant opportunities to integrate hazard mitigation principles and practices into the local decision-making process. Table 5.1 provides a summary of the relevant local plans, ordinances, and programs already in place or under development for Monroe County. A checkmark(v ) indicates that the given item is currently in place and being implemented. A plus sign(+) indicates that a jurisdiction is covered for that item under a county-implemented version. An asterisk(*) indicates that a jurisdiction is developing an item. Each of these local plans, ordinances, and programs should be considered available mechanisms for incorporating the requirements of the Local Mitigation Strategy. This information will help identify opportunities to address gaps, weaknesses, or conflicts with other initiatives and integrate the implementation of this plan with existing planning mechanisms where appropriate.

MANAGEMENT5.3.7.7 EMERGENCY Hazard mitigation is widely recognized as one of the four primary phases of emergency management, as is shown in Figure 5.1. In reality,mitigation is interconnected with all other phases and is an essential component of effective preparedness,response, and recovery. Opportunities to reduce potential losses through mitigation practices are most often implemented before a disaster event, such as through the elevation of flood-prone structures or by regular enforcement of policies that regulate development. However,mitigation opportunities can also be identified during immediate preparedness or response activities, such as installing storm shutters in advance of a hurricane. Furthermore, incorporating mitigation during the long-term recovery and redevelopment process following a disaster event is what enables a community to become more resilient over time.

A hazard mitigation plan, or local mitigation strategy, is a community's blueprint for how it intends to reduce the impact of natural and human-caused hazards on people and the built environment. The essential elements of a hazard mitigation plan include a risk assessment, capability assessment, and mitigation strategy. — All participating jurisdictions in this multi jurisdictional planning effort participated in and adopted the 2020 Monroe County Local Mitigation Strategy. — Key West and Layton/Key Colony Beach are currently(as of Spring 2025) developing vulnerability assessments and adaptation plans,which should be completed by the end of 2025. Key West's plan will culminate in a community-prioritized 10-year Adaptation Plan that identifies projects,budgets, and grants necessary to prepare the city and its residents for future climate hazards. — Islamorada and Marathon developed vulnerability assessments in 2024. III1\4arvroe courity,III:III III: IIL...ocaIII III l..'i' a:lii.iii s Ulia t . IIC: lge 2.,18 SECTIONS: CAPABILITY ASSESSMENT Monroe County and Islamorada, Layton, Key Colony Beach and Marathon are developing a combined vulnerability assessment beginning in 2025. SAS A disaster recovery plan serves to guide the physical, social, environmental, and economic recovery and reconstruction process following a disaster event. In many instances,hazard mitigation principles and practices are incorporated into local disaster recovery plans with the intent of capitalizing on opportunities to break the cycle of repetitive disaster losses. Disaster recovery plans can also lead to the preparation of disaster redevelopment policies and ordinances to be enacted following a hazard event. Monroe County's 2009 Recovery Plan outlines the following policies and procedures for post-disaster mitigation: 1. Assign a Hazard Mitigation Coordinator to lead the effort and provide overall coordination of the post—disaster mitigation planning process and grant proposal development. a. Ensure this person has the authority to cross departmental lines and ensure interdepartmental participation. 2. Review the County's Pre—Disaster Mitigation Plan; Determine updates and changes needed. 3. Participate on an Interagency Hazard Mitigation Committee (IHMC),made up of federal, state and local representatives who will prepare a report that serves as the basis for the hazard mitigation plan. a. The IHMC identifies opportunities for reducing or eliminating the long—term hazard risk to people and property. The IHMC report normally includes an analysis of the disaster incident, a historical perspective regarding disasters in the impacted area, and recommendations to bring various governmental agencies together to reduce the potential for future losses. 4. Coordinate with RF# 13 (Redevelopment(Planning and Community Development))to ensure the Post—Disaster Mitigation Plan and strategies are linked with land use plans, subdivision regulations,building codes, storm water management plans,the capital improvement plan, and other components of the County's Comprehensive Plan. 5. Identify and apply for federal and state post—disaster mitigation programs and funds. 6. Update the County's Hazard Mitigation Plan. In January 2020, Monroe County released its Post-Disaster Recovery Strategy,which serves as an operational framework intended to help Monroe County navigate resources that are available for long- term recovery, after FEMA Individual Assistance and Public Assistance are exhausted. Stakeholders from each of Monroe County's jurisdictions were included in the creation of the plan. The plan outlines long- term recovery procedures for various county functions. Long-term community recovery planning procedures that support post-disaster mitigation are listed below: Landfall to 3 months: — Work closely with Monroe County Emergency Management to understand data related to the FEMA Individual Assistance Program. Specifically, document the number of applicants,the amount of assistance provided to-date and the number of individuals denied assistance. It is also important to understand the number of households who are provided temporary sheltering assistance support through FEMA trailers,hotel lodging or other resources. — Review existing plans and ordinances to determine if adjustments need to be made to streamline recovery or address a specific need resulting from the disaster. III ����iii iiiro courity, IIL...ocaIII III l..'i' a t lii���.iii s Ulia te. J SECTIONS: CAPABILITY ASSESSMENT 3 to 6 months: — Coordinate with the Housing Recovery Team to conduct a survey of long-term housing repair needs that considers the appetite of homeowners for mitigation programs as well as voluntary buyout programs. 6 months to 1 year: — Coordinate the Housing Recovery Team to understand impacts on homeowners and renters and the need for new workforce housing to support long-term recovery. — Coordinate with the Economic Recovery Team to conduct a survey of local long-term business recovery needs (the survey conducted following Hurricane Irma is a great example). — Coordinate with the Infrastructure Recovery Team to understand infrastructure impacts and specific projects that will not be covered by the FEMA Public Assistance or the FEMA Hazard Mitigation Grant Program. — Coordinate with the Finance and Administration Teams to understand the long-term fiscal impacts the County and any additional support that may be needed to ensure a successful recovery. This can include financial assistance to support local tax revenue shortfalls or new positions that are needed to support long-term recovery and redevelopment. — Coordinate with the Finance and Administration to understand impacts to cultural and historic resources and any gaps in funding that may exist to ensure that these resources are restored. — Coordinate with the Environmental Restoration Team to understand impacts on the environment, including marine debris, fisheries, and other environmental concerns/impacts. — Coordinate with municipalities to understand how the disaster impacted their community and specific projects not covered by current resources,needed to support this recovery. — Conduct forums or listening sessions to get public feedback on important elements to preserve in the community and potential strategies to build-back in a way that may move the community in a more resilient direction in the future. 1 to 2 years: — Ensure that the collection of unmet needs and action plan development processes are transparent by posting relevant information to a central website for recovery and offering opportunities in-person and online for community members to ask questions and offer feedback on projects. — Work closely with the Public Information Officer to ensure that all opportunities to provide feedback are broadly disseminated through all advertising venues including social media,press releases, etc. — Work with schools and non-profit agencies to develop creative ways to involve students and the art community in soliciting feedback on redevelopment. — Develop a long-term recovery plan that builds on the information collected to date and outlines clear actions that are needed,with funding sources aligned to guide recovery and long-term redevelopment. — As resources are available to support long-term recovery, coordinate closely with municipalities and other eligible stakeholders to ensure that the opportunities are seized. 2+years: — Continue close coordination with all stakeholders as funding continues to roll out and provide webinars,meetings,newsletters and other media to get the word out about grant opportunities and facilitate a forum for communication. Key West has its own post-disaster redevelopment plan. IIIAarvroe courity,III:III III: IIL...ocaIII III l..'i' a:lii.iii s Ulia t ... SECTIONS: CAPABILITY ASSESSMENT An emergency operations plan outlines responsibilities and how resources will be deployed during and following an emergency or disaster. — All participating jurisdictions are covered under the Monroe County Emergency Management Comprehensive Plan,which was passed in 2022. S A continuity of operations plan establishes a chain of command, line of succession, and plans for backup or alternate emergency facilities in case of an extreme emergency or disaster event. — All participating jurisdictions are covered under the Monroe County Continuity of Operations Plan. The implementation of hazard mitigation activities involves agencies and individuals beyond the emergency management profession. Stakeholders may include local planners,public works officials, economic development specialists, and others. In many instances, concurrent local planning efforts will help to achieve or complement hazard mitigation goals. A comprehensive or land use plan establishes the overall vision for what a community wants to be and serves as a guide for future governmental decision making. Typically, a comprehensive plan contains sections on demographic conditions, land use,transportation elements, and community facilities. Given the broad nature of the plan and its regulatory standing in many communities,the integration of hazard mitigation measures into the comprehensive plan can enhance the likelihood of achieving risk reduction goals, objectives, and actions. — All participating jurisdictions have a comprehensive plan. — Key Colony Beach and Islamorada are currently updating their comprehensive plans. A capital improvements plan guides the scheduling of spending on public improvements. A capital improvements plan can serve as an important mechanism for guiding future development away from identified hazard areas. Limiting public spending in hazardous areas is one of the most effective long- term mitigation actions available to local governments. — All participating jurisdictions have a capital improvements plan in place. A historic preservation plan is intended to preserve historic structures or districts within a community. An often-overlooked aspect of the historic preservation plan is the assessment of buildings and sites located in areas subject to natural hazards, and the identification of ways to reduce future damages. This may involve retrofitting or relocation techniques that account for the need to protect buildings that do not meet current building standards or are within a historic district that cannot easily be relocated out of harm's way. 1 of the 6 participating jurisdictions have a historic preservation plan in place or under development. Zoning represents the primary means by which land use is controlled by local governments. As part of a community's police power,zoning is used to protect the public health, safety, and welfare of those in a IIN4arvroe Courity,III:III III: IIL...ocdI III l..'i' a:lii.iii S Ulia t . SECTIONS: CAPABILITY ASSESSMENT given jurisdiction that maintains zoning authority. A zoning ordinance is the mechanism through which zoning is typically implemented. Since zoning regulations enable municipal governments to limit the type and density of development, a zoning ordinance can serve as a powerful tool when applied in identified hazard areas. — All participating jurisdictions have a zoning ordinance in place and enforce zoning regulations. A subdivision ordinance is intended to regulate the development of residential, commercial,industrial, or other uses, including associated public infrastructure, as land is subdivided into buildable lots for sale or future development. Subdivision design that accounts for natural hazards can dramatically reduce the exposure of future development. All participating jurisdictions have a subdivision ordinance in place and enforce subdivision regulations. muIVV Ioouum muuV y muuu Building codes regulate construction standards. In many communities,permits and inspections are required for new construction. Decisions regarding the adoption of building codes (that account for hazard risk), the type of permitting process required both before and after a disaster, and the enforcement of inspection protocols all affect the level of hazard risk faced by a community. — All participating jurisdictions have building codes in place and enforce building code requirements. The adoption and enforcement of building codes by local jurisdictions is routinely assessed through the Building Code Effectiveness Grading Schedule(BCEGS)program, developed by the Insurance Services Office, Inc. (ISO). The results of BCEGS assessments are routinely provided to ISO's member private insurance companies,which in turn may offer ratings credits for new buildings constructed in communities with strong BCEGS classifications. The expectation is that communities with well-enforced, up-to-date codes should experience fewer disaster-related losses, and as a result should have lower insurance rates. In conducting the assessment, ISO collects information related to personnel qualification and continuing education, as well as number of inspections performed per day. This type of information combined with local building codes is used to determine a grade for that jurisdiction. The grades range from 1 to 10,with a BCEGS grade of 1 representing exemplary commitment to building code enforcement, and a grade of 10 indicating less than minimum recognized protection. Flooding represents the greatest natural hazard facing the nation,yet the tools available to reduce the impacts associated with flooding are among the most developed when compared to other hazard-specific mitigation techniques. In addition to approaches that cut across hazards such as education, outreach, and the training of local officials,the National Flood Insurance Program(NFIP) contains specific regulatory measures that enable government officials to determine where and how growth occurs relative to flood hazards. Participation in the NFIP is voluntary for local governments; however,program participation is strongly encouraged by FEMA as a first step for implementing and sustaining an effective hazard mitigation program. It is therefore used as part of this capability assessment as a key indicator for measuring local capability. To participate in the NFIP, a county or municipality must adopt a local flood damage prevention ordinance that requires established minimum building standards in the floodplain. These standards require that all new buildings and substantial improvements to existing buildings be protected from damage by a 1%-annual-chance flood event and that new development in the floodplain not exacerbate existing flood IIIAarvroe c ouii III:III &II:) IIL...ocaIII III l..'i' a:lii.iii s Ulia t ... SECTIONS: CAPABILITY ASSESSMENT problems or increase damage to other properties. Within the last five years, Monroe County and its incorporated communities adopted flood damage prevention ordinance updates establishing minimum elevation requirements communitywide,protecting development not only in the SFHA but also in areas currently mapped as moderate and low risk zones. A key service provided by the NFIP is the mapping of identified flood hazard areas. Flood Insurance Rate Maps (FIRMs) are used to assess flood hazard risk,regulate construction practices, and set flood insurance rates. FIRMs are an important source of information to educate residents, government officials, and the private sector about the likelihood of flooding in their community. All jurisdictions in Monroe County participate in the NFIP. NFIP policy and claim information for each participating jurisdiction are provided in the jurisdictional annexes along within an overview of NFIP participation activities and higher standards of floodplain management enforced in each community. All jurisdictions will continue to comply with all required provisions of the NFIP. Floodplain management is managed through zoning ordinances,building code restrictions, and the county building inspection program. The jurisdictions will coordinate with FDEM and FEMA to develop maps and regulations related to Special Flood Hazard Areas within their jurisdictional boundaries and,through a consistent monitoring process,will design and improve their floodplain management program in a way that reduces the risk of flooding to people and property. Additional details on Community Rating System (CRS)participation and substantial damage management procedures are provided below. An additional indicator of floodplain management capability is active participation in the CRS. The CRS is an incentive-based program that encourages communities to undertake defined flood mitigation activities that go beyond the minimum requirements of the NFIP. Each of the CRS mitigation activities is assigned a point value. As a community earns points and reaches identified thresholds,they can apply for an improved CRS class. Class ratings,which range from 10 to 1 and increase on 500-point increments, are tied to flood insurance premium reductions. Every class improvement earns an additional 5 percent discount for NFIP policyholders,with a starting discount of 5 percent for Class 9 communities and a maximum possible discount of 45 percent for Class 1 communities. Community participation in the CRS is voluntary. Any community that is in full compliance with the rules and regulations of the NFIP may apply to FEMA for a CRS classification better than class 10. The CRS application process has been greatly simplified over the past several years,based on community comments intended to make the CRS more user friendly, and extensive technical assistance is available for communities who request it. All communities in Monroe County participate in the Community Rating System. Each community's CRS Class is shown in Table 5.2. Key West is working toward a CRS improvement to a Class 4.

Islamorada's was completed and approved in 2024. Monroe County is updating their previous WMP that was adopted in 2019. The NFIP requires that participating communities regulate and enforce substantial damage and substantial improvement procedures such that, at a minimum,buildings that are damaged to 50 percent or more of their market value or improved by 50 percent or more of their market value are required to be brought into compliance with flood damage prevention regulations for new development, such as being elevated to the freeboard requirement.

An open space management plan is designed to preserve,protect, and restore largely undeveloped lands in their natural state, and to expand or connect areas in the public domain such as parks, greenways, and other outdoor recreation areas. In many instances open space management practices are consistent with the goals of reducing hazard losses, such as the preservation of wetlands or other flood-prone areas in their natural state in perpetuity. — The City of Marathon is in the process of developing a Parks, Recreation, and Open Space Master Plan. — All other jurisdictions do not have an open space management plan. A stormwater management plan is designed to address flooding associated with stormwater runoff. The stormwater management plan is typically focused on design and construction measures that are intended to reduce the impact of more frequently occurring minor urban flooding. — 4 of 6 participating jurisdictions have a stormwater management plan. — The City of Islamorada is currently developing an updated stormwater management plan, which is expected to be completed in 2026. — Monroe County, Key West,Layton,Key Colony Beach and Marathon are all currently developing CRS Activity 452.b Watershed Management Plans.

The ability of a local government to develop and implement mitigation projects,policies, and programs is directly tied to its ability to direct staff time and resources for that purpose. Administrative capability can be evaluated by determining how mitigation-related activities are assigned to local departments and if there are adequate personnel resources to complete these activities. The degree of intergovernmental coordination among departments will also affect administrative capability for the implementation and success of proposed mitigation activities. Technical capability can generally be evaluated by assessing the level of knowledge and technical expertise of local government employees, such as personnel skilled in using GIS to analyze and assess IIMarvroe Courity,III:III III: IIL...ocdI III l..'i' a:lii.iii SUrategy ...

The ability of a local government to implement mitigation actions is often dependent on the amount of money available. This may take the form of outside grant funding awards or locally based revenue and IIMarvroe Courity,III:III III: IIL...ocdI III l..'i' a:lii.iii S Ulia t ... ..18 SECTIONS: CAPABILITY ASSESSMENT financing. The costs associated with mitigation policy and project implementation vary widely. In some cases,policies are tied primarily to staff time or administrative costs associated with the creation and monitoring of a given program. In other cases, direct expenses are linked to an actual project such as the acquisition of flood-prone houses, which can require a substantial commitment from local, state, and federal funding sources. The Local Capability Self-Assessment was used to capture information on each jurisdiction's fiscal capability through the identification of locally available financial resources. Table 5.4 provides a summary of the results for each jurisdiction with regard to relevant fiscal resources.

This type of local capability refers to the mitigation strategies and actions that are developed by the communities in this plan. All communities in Monroe County pursue mitigation grant funding to implement property protection activities, including building elevations and acquisitions, as well as structural projects. The LMSWG coordinates regularly to review mitigation grant funding opportunities and prioritize projects for grant applications. In the past five years,Key West received an$11 million BRIC grant, funding a fire station and EOC, received funds from FDEP to develop a vulnerability assessment, and worked with the Florida Division of Historic Resources to complete an assessment and flood mitigation of historic properties. Islamorada has been working with USAGE on the Florida Keys Costal Storm Risk Management Project which will address US-I revetment on the Fill Keys, home elevations, and critical infrastructure floodproofing. LiDAR mapping is occurring throughout the county will support evaluation of potential elevation proj ects. ....................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................... 5.3.6 POLITICAL CAPABILITY One of the most difficult capabilities to evaluate involves the political will of a jurisdiction to enact meaningful policies and projects designed to reduce the impact of future hazard events. Hazard mitigation may not be a local priority, or it may conflict with or be seen as an impediment to other goals of the community, such as growth and economic development. Therefore,the local political climate must be considered in designing mitigation strategies, as it could be the most difficult hurdle to overcome in accomplishing their adoption and implementation. In completing the Local Capability Self-Assessment, HMPC representatives from each community were asked to rate political support as they perceive it and identify general examples of local political capability, such as guiding development away from identified hazard areas,restricting public investments or capital improvements within hazard areas, or enforcing local development standards that go beyond minimum state or federal requirements (e.g.,building codes, floodplain management, etc.). Table 5.6 below summarizes the different government structures in the jurisdictions as well as whether or not the governing bodies are supportive of mitigation efforts.

IIIIII As previously discussed, one of the reasons for conducting a capability assessment is to examine local capabilities to detect any existing gaps or weaknesses within ongoing government activities that could hinder proposed mitigation activities and possibly exacerbate community hazard vulnerability. These gaps,which indicate opportunities for improvement, have been identified for each jurisdiction in the tables found throughout this section. The participating jurisdictions used the capability assessment as part of the basis for the mitigation actions that are identified in Section 7; therefore, each jurisdiction addresses their ability to expand on and improve their existing capabilities through the identification of their mitigation actions. Each jurisdiction is unique in its planning, regulatory, fiscal,political, and outreach capabilities; additional details on jurisdictional capability, including existing mitigation in comprehensive planning efforts, and other details of local planning can be found in the Planning Area Profile.

This section describes the process for developing the mitigation strategy for the Monroe County Local Mitigation Strategy. It describes how the Region met the requirements for Planning Step 6 (Set Goals), Planning Step 7 (Review Possible Activities), and Planning Step 8 (Draft an Action Plan). This section includes the following sub-sections: — 6.1 Goals and Objectives — 6.2 Identification&Analysis of Mitigation Activities ....................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................... 6.11111111111 GOA���.....................S Requirement§201.6(c)(3)(i):[The mitigation strategy section shall include a]description of mitigation goals to reduce or avoid long-term vulnerabilities to the identified hazards. Goal setting builds upon the findings of Section 4,which documents the hazards and associated risks that threaten Monroe County, including the vulnerability of structures, infrastructure, and critical facilities. Section 5 evaluates each jurisdiction's capacity to reduce the impact of hazards. The intent of Goal Setting is to identify areas where improvements to existing capabilities and reductions in existing vulnerabilities can be made so that overall risk is reduced. Goals also guide the review of possible mitigation measures. This plan needs to make sure that recommended actions are consistent with what is appropriate for the County and the incorporated municipalities. Mitigation goals need to reflect community priorities and should be consistent with other local plans. — Goals are general guidelines that explain what is to be achieved. They are usually broad-based policy type statements, long term and represent global visions. Goals help define the benefits that the plan is trying to achieve. — Objectives are short term aims that,when combined, form a strategy or course of action to meet a goal. Unlike goals, objectives are specific and measurable. ....................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................... 6,,,,,7,,,,,7 COORDINATION WITH OTHER PLANNING EFFORTS The goals of this plan need to be consistent with and complement the goals of other local planning efforts. The primary planning documents that the goals of this plan should complement and be consistent with are the County and participating jurisdictions' comprehensive plans. Comprehensive plans are important because they are developed and designed to guide future growth within their communities so they encompass long-term strategies and can be critical to reducing long term vulnerabilities. Keeping the Local Mitigation Strategy and Comprehensive Plans consistent ensures that land development is done with awareness and understanding of hazard risk and that mitigation projects complement rather than contradict community development objectives. Another local resource that was reviewed for coordination was the Southeast Florida Regional Climate Change Compact Regional Climate Action Plan 3.0; Monroe County and all incorporated jurisdictions are part of the compact and the associated climate action plan.

All plans approved by FEMA after October 1, 2008, must also address the jurisdiction's participation in the NFIP, and continued compliance with NFIP requirements,as appropriate. To identify and select mitigation projects that support the mitigation goals and objectives, the risks and vulnerabilities associated with all hazards identified and evaluated in Section 4 Hazard Identification and Risk Assessment were evaluated for mitigation opportunities. The LMSWG analyzed viable mitigation options that supported the identified goals and objectives, addressed key problems,risks, or vulnerabilities, and aligned with other local plans and efforts. The LMSWG was provided with the following list of mitigation categories which are utilized as part of the CRS planning process but are also applicable to multi-hazard mitigation: — Prevention — Emergency Services — Property Protection — Structural Projects — Natural Resource Protection — Public Education The LMSWG was also provided with examples of potential mitigation actions for each of the above categories. The LMSWG was instructed to consider both future and existing buildings in evaluating possible mitigation actions. Facilitated discussions took place to examine and analyze the options. The LMSWG also considered which actions from the previous plan and subsequent annual updates that were not already completed should be continued in this action plan. A more detailed review of possible actions within each mitigation category that were reviewed by the LMSWG is provided in Appendix C. Actions that were completed or deleted are detailed in Section 2.9. ....................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................... 6 II�� IIIIII� II IIu�mlllllul Monroe County employs a three-step mitigation action prioritization process. Step One, defined in this section, is to identify a full range of possible mitigation activities and create a preliminary list of actions to pursue. Steps Two and Three are detailed in Appendix D. In the process of identifying continuing and new mitigation actions,the LMSWG was provided with a set of prioritization criteria to assist in deciding why one recommended action might be more important,more effective, or more likely to be implemented than another. LMSWG members were asked to rate each action with an approach modified from the FEMA STAPLEE criteria and then evaluate the general efficacy of each action. The LMSWG was first asked to give each action a positive(1 point),neutral (0 points), or negative(-I point)rating for each of the STAPLEE elements: — Socially Acceptable: Is the action acceptable to the community?Does it have a greater impact on a certain segment of the population?Are the benefits fair? — Technically Feasible: Is the action technically feasibly? Is it a long-term solution to the problem? Does it capitalize on existing planning mechanisms for implementation? — Administrative Resources: Are there adequate staffing, funding and other capabilities to implement the project? Is there adequate additional capability to ensure ongoing maintenance? Marvroe County,III::III III: IIM u.1 III t oc III III ii t ii g a t ii iiir'i strategy J a iiir''i u a iii�, 2,0 2,6 IIC: 22,5 SECTION 6: MITIGATION STRATEGY — Politically Supported: Will there be adequate political and public support for the project?Does the project have a local champion to support implementation? — Legally Allowable: Does the community have the legal authority to implement the action? — Economically Sound: Can the action be funded locally?Will the action need to be funded by an outside entity, and has that funding been secured? How much will the project cost? Can the benefits be quantified, and do they outweigh the costs? — Environmentally Sound: Does the action comply with environmental regulations? Does the action meet the community's environmental goals?Does the action impact land,water, endangered species, or other natural assets? Each action could receive a STAPLEE score between 7 and-7; however,no action was considered further if it scored less than 0 points. Next, the LMSWG was asked to consider each action's potential efficacy by answering the following questions with unlikely(0 points),maybe (1 point),probably(2 points), or definitely(3 points): — Will the action result in lives saved? — Will the action reduce property damages? — Will the action reduce the need for response actions? — Will the benefits exceed the cost? Each action could receive an additional effectiveness score of 0 to 12. Using these prioritization criteria, the LMSWG was able to score each action on a scale of 0 to 19. The prioritization ranking, simplified as High, Medium, or Low, for each mitigation action considered by the LMSWG is provided in the Mitigation Action Plan below. These priority rankings are defined as follows: — High: 14 to 19 points — Medium: 7 to 13 points — Low: 0 to 6 points In accordance with the DMA requirements, an emphasis was placed on the importance of a benefit-cost analysis in determining action priority, as reflected in the prioritization criteria above. For each action,the LMSWG considered the benefit-cost analysis in terms of: — Ability of the action to address the problem — Contribution of the action to save life or property — Available technical and administrative resources for implementation — Availability of funding and perceived cost-effectiveness The consideration of these criteria helped to prioritize and refine mitigation actions but did not constitute a full benefit-cost analysis. The cost-effectiveness of any mitigation alternative will be considered in greater detail through performing benefit-cost project analyses when seeking FEMA mitigation grant funding for eligible actions associated with this plan. ....................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................... 6m umu°pm uuuuuuuu uuuuuuuu uuuuuuu uuuuuum uuuuuum uuuuuuuuuuuuu uuuuuuu uuuuuuuuuuuuu uuuuuu°upplll uuuuuuuu uuuuuuuu i um , mummol Illlullliiul a uml uuuuum uuuuum uuuuuuuuuuuu uummmuuuuu uuuuuuu uuuuu iIIVi uuuuuuuuum. uuuuum uuuuuuuuuuuuu uuuuuuuuuuuuu uuumuun uuuuuuuuuuuum uuuuuuuuuuuum uuu In keeping with FEMA requirements for plan updates,the LMSWG evaluated mitigation actions identified in the previous plan to determine their current implementation status, including if an action was completed or, if not,whether it should be carried forward for future implementation or deleted from the IIIAarvroe courity,III:III III:I III .III ill .iii iii ..lii ii iii III Ill ou III III iii t iii atiii aii°m Strategy Jaiir'iu a�i a 2,02,6 IIC: g e 2,a2,6 SECTION 6: MITIGATION STRATEGY mitigation action plan.

Prioritization shall include a special emphasis on the extent to which benefits are maximized according to a cost benefit review of the proposed projects and their associated costs. This section provides the updated mitigation action plan,which was developed to reduce the risk and vulnerability of people,property, infrastructure, and natural and cultural resources to future disaster losses. Emphasis was placed on both future and existing development. Each mitigation action recommended for implementation is listed in these tables along with detail on the applicable jurisdictions,hazards addressed,the goal and objective addressed,the priority rating,the lead agency responsible for implementation,potential funding sources for the action, a projected implementation timeline(noted as the projected timeframe for completion), and the 2025 status and comments on this status for actions that were carried forward from the 2020 plan. n� III:IIL...

Implementation and maintenance of the plan is critical to the overall success of hazard mitigation planning. This section discusses how the Mitigation Action Plan will be implemented by participating jurisdictions and outlines the method and schedule for monitoring,updating, and evaluating the plan. This section also discusses incorporating the plan into existing planning mechanisms and how the public will continue to be involved in the planning process. It consists of the following three subsections: 8.1 Distribution 8.2 Implementation 8.3 Monitoring,Evaluation, and Enhancement 8.4 Continued Public Involvement ....................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................... 8 11111111111 II Upon adoption of the 2025 Monroe County Local Mitigation Strategy Update, the plan in its entirety will be posted on the Monroe County Emergency Management Department's website.Notice of its availability will be distributed to relevant Federal and State agencies, as well as local elected officials. The plan will be maintained on the Monroe County Emergency Management Department's website for public access throughout its duration. ...............................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................8 ........................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................ � MISSION IIIIIIIIIIIIIIIIIIIIIIIIII II IIIII IIII IIiliq�N4 ullllll'iiuuuuuuuuuum ���11111111111111111111 uuuuuuuuuuuum uuuuuuuuuuuuu Each jurisdiction participating in this plan update is responsible for implementing specific mitigation actions as prescribed in the Mitigation Action Plan(found in Section 7). In the Mitigation Action Plan, every proposed action is assigned to a specific local department or agency to ensure responsibility and accountability and increase the likelihood of subsequent implementation. Jurisdiction may update the actions applicable to their jurisdiction as needed without altering the broader focus of the LMS. In addition to the assignment of a local lead department or agency, an implementation timeline or a specific implementation date or window has been assigned to each mitigation action to help assess whether reasonable progress is being made toward implementation. The participating jurisdictions will seek outside funding sources to implement mitigation projects in both the pre-disaster and post-disaster environments. When applicable,potential funding sources have been identified for proposed actions listed in the Mitigation Action Plan. An important implementation mechanism that is highly effective and low-cost is integration of the Local Mitigation Strategy recommendations and their underlying principles into other plans and mechanisms. Where possible,plan participants will use existing plans and/or programs to implement the Mitigation Action Plan. LMSWG group members may consider integrating the findings, recommendations, and actions presented in the LMS into the following plans and ordinances, among others: — Comprehensive Plans; — Subdivision Ordinances; — Zoning Ordinances&Land Use Plans; — Building Codes; n� r e courity,III:IIL... III:II iii iii iii°:iii iii III IIL...o c III III iii�iii a t ii�r'i �m iii III . 1 , � iii.m.�iii. ..02 IIC:� ,61 SECTION 8: PLAN MAINTENANCE — Emergency Operations Plans; — Climate Change/Sea Level Rise Plans; — Capital Improvements Plans; — Small Area Plans; and — Repetitive Loss Plans; — Transportation Plans. Monroe County and its jurisdictions acknowledge the risk and the associated effects of hazards such as high winds,tropical cyclones and storm surge, flooding, and sea level rise. As such, data regarding risk assessments and options to mitigate such risk are incorporated into existing community planning mechanisms,which are detailed in each community's individual annexes. Moving forward, it will be the responsibility of the LMSWG representatives from each participating jurisdiction to continue to determine and pursue opportunities for integrating the findings,requirements, and strategies of this plan with other local planning documents. The LMSWG is also responsible for ensuring that the goals and strategies of new and updated local planning documents for their jurisdictions or agencies are consistent with the goals and actions of the Local Mitigation Strategy and will not contribute to increased hazard vulnerability in the planning area. Methods for integration may include: — Monitoring other planning/program agendas; — Attending other planning/program meetings; — Participating in other planning processes; and — Monitoring community budget meetings for other community program opportunities. Many identified mitigation initiatives are capital projects,the implementation of which is usually dependent upon the availability of funding. When such initiatives are prioritized, and funding is sought, each jurisdiction will comply with its existing rules regarding inclusion of projects in its Capital Improvement Plan or other budget and planning processes and documents. Opportunities to integrate the requirements of this plan into other local planning mechanisms shall continue to be identified through future meetings of the LMSWG and through the five-year review process described herein. Although it is recognized that there are many possible benefits to integrating components of this plan into other local planning mechanisms,the development and maintenance of this stand-alone Local Mitigation Strategy is deemed by the LMSWG to be the most effective and appropriate method to implement local hazard mitigation actions at this time. .......................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................

MAINTENANCE8,33 ROLE OF LMSWG IN IMPLEMENTATION, MONI 111117111111111110PING AND With adoption of this plan, each jurisdiction will be responsible for the implementation and maintenance of their mitigation actions. The LMS Coordinator from Monroe County Emergency Management will take the lead in all plan monitoring and update procedures. As such, each jurisdiction agrees to continue their relationship with the LMSWG and: — Act as a forum for hazard mitigation issues; — Disseminate hazard mitigation ideas and activities to all participants; — Pursue the implementation of high-priority, low/no-cost recommended actions; — Ensure hazard mitigation remains a consideration for community decision makers; li �iii .d ai,4 IIL...o III iii t lii ii iii*.,m Strategy wi"°W&i,. .: .6 SECTION 8: PLAN MAINTENANCE — Maintain a vigilant monitoring of multi-objective cost-share opportunities to help the community implement the plan's recommended actions for which no current funding exists; — Monitor and assist in implementation and update of this plan; — Report on plan progress and recommended revisions to the local governing boards; and — Inform and solicit input from the public. The LMSWG's primary duty moving forward is to see the plan successfully carried out and report to the local governing boards,FDEM,FEMA, and the public on the status of plan implementation and mitigation opportunities. Other duties include reviewing and promoting mitigation proposals, considering stakeholder concerns about mitigation,passing concerns on to appropriate entities, and providing relevant information for posting on community websites (and others as appropriate). Simultaneous to these efforts, it will be important to maintain a constant monitoring of funding opportunities that can be leveraged to implement some of the costlier recommended actions. This will include creating and maintaining a bank of ideas on how to meet local match or participation requirements. When funding does become available, the County will be positioned to capitalize on the opportunity. Funding opportunities to be monitored include special pre- and post-disaster funds, state and federal earmarked funds,benefit assessments, and other grant programs, including those that can serve or support multi-objective applications. ....................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................... Plan maintenance implies an ongoing effort to monitor and evaluate plan implementation and to update the plan as progress,roadblocks, or changing circumstances are recognized. The LMS Coordinator will be responsible for convening the LMSWG and initiating regular reviews. Regular maintenance will take place through quarterly conference calls and an annual meeting of the LMSWG. The LMSWG will also convene to review the plan after significant hazard events. The criteria recommended in 44 CFR 201 and 206 will be utilized in reviewing and updating the plan. ....................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................... . .3 MAINTENANCE Evaluation of progress can be achieved by monitoring changes in vulnerabilities identified in the plan. Changes in vulnerability can be identified by noting: — Decreased vulnerability as a result of implementing recommended actions; — Increased vulnerability as a result of failed or ineffective mitigation actions; and/or — Increased vulnerability as a result of new development(and/or annexation). Updates to this plan will: — Consider changes in vulnerability due to project implementation; — Document success stories where mitigation efforts have proven effective; — Document areas where mitigation actions were not effective; — Document any new hazards that may arise or were previously overlooked; — Incorporate new data or studies on hazards and risks; — Incorporate new capabilities or changes in capabilities; — Incorporate growth and development-related changes to asset inventories; and — Incorporate new project recommendations or changes in project prioritization. li �iii .d ai,4 IIL...o III iii t lii ii iii*.m Strategy J a iii`.m U a iii. .: .6 SECTION 8: PLAN MAINTENANCE To ensure effectiveness in meeting the goals set forth in this plan,the LMS working group will convene quarterly via conference call. More specifically, quarterly reviews will monitor changes to the following information: — Community growth or change in the past quarter along with updates to community plans. The implementation status of the mitigation strategy and individual mitigation action items,including noting completed items or progress made toward completion, amended items, and deleted items due to changed priorities or otherwise. — The number of substantially damaged or substantially improved structures by flood zone. — The renovations and mitigation activities to public infrastructure including water, sewer, drainage, roads, bridges, gas lines, and buildings. — The number of building and assets protected or mitigation. — Natural hazard occurrences that required activation of any Emergency Operations Center(EOC)in the County and whether the event resulted in a presidential disaster declaration. — Natural hazard occurrences that were not of a magnitude to warrant activation of the EOC or a federal disaster declaration but were severe enough to cause damage in the community or closure of businesses, schools, or public services. — The dates of hazard events descriptions. — Documented damages due to the event; include details on closure of places of employment or schools and the number of days closed, road or bridge closures due to the hazard event and length of time closed, and an assessment of the number of private and public buildings damaged and whether the damage was minor, substantial, major, or if buildings were destroyed. The assessment will include residences,mobile homes, commercial structures, industrial structures, and public buildings, such as schools and public safety buildings. 2 ANNI,.,,,,,,IAL EVALUATION AND UPDATES Per Florida Administrative Code Chapter 27P-22, and to ensure the LMS is current and continues to serve the interest of residents and visitors,the LMSWG will perform annual evaluations. By the end of September of each year,the LMS Coordinator will notify LMSWG members of the need to identify and compile revisions brought up through quarterly reviews. Working group members will submit any proposed revisions to Emergency Management to be discussed at the annual LMSWG meeting. Minor revisions may be handled by addenda while significant revisions will be submitted to FDEM. The LMS Coordinator will compile the proposed revisions and submit them to the Department of Community Affairs and FDEM by the last working day of January. Revisions may be warranted due to: — Hazard events that have occurred prompting a change in the characterization of risk and vulnerability or warrant the consideration of additional initiatives; — Significant changes, such as addition or deletion,to the critical facilities lists; — Changes to the NFIP's list of Repetitive Loss Properties; — Changes in develop that result in changes to the characterization of people and property that are at risk; — Changes to the list of mitigation initiatives including the addition of new initiatives, or the deletion or completion of existing initiatives; — Changes in department organization,regulations, comprehensive plans, and the like; and — Changes necessary to comply with State and Federal program requirements. li �iii .d ai,4 IIL...o III iii t lii ii iii*.m Strategy wi"m �&i. .: .6 SECTION 8: PLAN MAINTENANCE In the event of a major hazard event such as a hurricane or tropical storm,the LMSWG will convene after the event to discuss its impacts and initiate a discussion on how the LMSWG can influence mitigation in the recovery process. Whether shortly after an event or in response to receiving notice from FDEM that mitigation funds are available,the LMSWG will consider which project and initiatives will be prioritized. The LMS Coordinator will be responsible for reconvening the LMSWG for the Five-Year plan update. In part,this revision will be to incorporate the material collected for the annual updates in the four years prior. The five-year update will be submitted to FDEM and FEMA Region 4. With this plan update anticipated to be completed by January 2026,the next plan update for Monroe County will be completed by January 2031. ....................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................... 8 IllllhCO .............................. 1,................J Continued public involvement is imperative to the overall success of the plan's implementation. The quarterly review process will provide an opportunity to solicit participation from new and existing stakeholders and to publicize success stories from the plan implementation and seek additional public comment. Efforts to involve the public in the maintenance, evaluation and revision process may include: — Advertising LMSWG meetings in the local newspaper,public bulletin boards and/or local government office buildings; — Designating willing citizens and private sector representatives as official members of the LMSWG; — Utilizing local media to update the public of any maintenance and/or review activities; — Utilizing local government websites to advertise any maintenance and/or review activities; — Maintaining copies of the plan in public libraries or other appropriate venues; — Posting annual progress reports on the Plan to local government websites; — Heavy publicity of the plan and potential ways for the public to be involved after significant hazard events,tailored to the event that has just happened; — Keeping websites, social media outlets, etc. updated; — Drafting articles for the local community newspapers/newsletters; — Utilizing social media accounts (e.g. Twitter, Facebook). ....................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................... . . When the LMSWG reconvenes for the five-year update, they will coordinate with all stakeholders participating in the planning process including those that joined the committee since the planning process began to update and revise the plan. In reconvening,the LMSWG will be responsible for coordinating the activities necessary to involve the greater public, including disseminating information through a variety of media channels detailing the plan update process. As part of this effort,public meetings will be held and public comments will be solicited on the plan update draft. li �iii .d ai,4 IIL...o III iii t lii ii iii*.m Strategy wi"m �&i. .: .6 IIC:)E!Ige as 641 SECTION 9: PLAN ADOPTION 1111111111111) iiiiiiiiiiiiiiiiiiiiiillillillillillillillilI ...............................A �4 A 0 0 �4 Requirement §201.6(c)(5): [The plan shall include] documentation that the plan has been formally approved by the governing body of the jurisdiction requesting approval of the plan (e.g., City Council, County Commissioner,Tribal Council).

CONTIN(JED NFIP COMPLIANCE Monroe County entered the NFIP in 1973 by adoption of an ordinance that complies with the requirement of the program. The Floodplain Management Ordinance specifies standards for residential and non- residential construction and water supply and sanitary sewer systems that are located in the SFHA. It prohibits the alteration of sand dunes,mangrove stands, or wetlands if such alterations would increase the potential for flooding. The dominant standard in the ordinance requires that the lowest floor of buildings (including manufactured homes)be elevated to or above base flood levels. Enclosures below the elevated lowest floor are allowed only if they meet requirements specific to the flood zone. To ensure continued compliance with the NFIP,the County will continue to: — Enforce the adopted floodplain management ordinance, including reviewing all development proposals within the SFHA for compliance and inspection of permitted development and unpermitted activities; — Maintain records pertaining to development, including flood maps and Letters of Map Change,which shall be available for public inspection; — Notify the public when there are proposed changes to the ordinance or FIRMS; and — Promote the purchase of NFIP flood insurance policies as financial protection. ....................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................... ENCLOSURE.53 BELOW ELEVATED BUILDINGS In 1995, FEMA notified Monroe County that the illegal conversion and occupancy of enclosures below elevated residential structures had resulted from a deficiency in the County's enforcement of its IIM t.III it l LA iii iiisc lii(ft ii ai,4II IIL... c z)III III iii t iii a iii a Illr � . 3 ANNEX A:MONROE COUNTY UNINCORPORATED AREAS floodplain management regulations. The County was directed to correct the deficiency or face suspension from the NFIP. The BOCC appointed a task force to address the problem which developed the "Flood Insurance Inspection Program."NFIP-insured homes with enclosures below the Base Flood Elevation were to be inspected to identify deficiencies; these were to be corrected in order for flood insurance policies to be written. Over 2,000 properties had been inspected through 2009; 1,600 had been brought into compliance. In mid-2014, FEMA ended the pilot program but directed Monroe County to continue enforcement.

ANNEX A:MONROE COUNTY UNINCORPORATED AREAS A.2.4 WILDFIRE Table A.15 summarizes the acreage in unincorporated Monroe County that falls within the Functional Wildland Urban Interface(WLTI), categorized into zones that describe the wildfire risk mitigation activities appropriate for each zone. Areas in the Functional WUI are those areas where development and building structures may intermix with burnable land cover. Approximately, 1 percent of unincorporated Monroe County is categorized as having direct exposure to wildfire risk within the Functional WiJI. Table A.75-Functional Wildland Urban Interface,Unincorporated Monroe County 1� Rill I I i riii I M11111 I il�i 11 ill M11 �i il i i Till I Ili I( Direct Exposure 3,608 1% Indirect Exposure 6,518 2% Critical Fireshed 457638 14% Sources of Ember Load to Buildings 9,347 3% Little to No Exposure 3,863 1% loom Water 251,004 78% Source:Southern Wildfire Risk Assessment Figure A-19 depicts the Functional WUI for Monroe County,including incorporated areas. Figure A-20 depicts Burn Probability based on landscape conditions,percentile weather,historical ignition patterns, and historical prevention and suppression efforts. Fire Intensity Scale, which indicates the potential severity of fire based on fuel loads,topography,and other factors, is depicted in Figure A-21. Functional WUI areas are distributed throughout the county; the mainland is largely outside of any direct exposure in the Functional WUI. The biggest clusters of direct exposure are shown through out unincorporated areas of the Keys. Burn probability is low throughout the unincorporated areas on the Keys with some swaths of moderate burn probability in the Middle and Upper Keys areas. On the mainland,burn probability is low near the coast but much of the area included in Everglades National Park has a high burn probability. There are pockets of high fire intensity throughout the unincorporated areas of the County; areas with particularly large clusters include Big Pine Key and the mainland areas of Monroe County. Table A.16 provides building counts and values for critical facilities by FEMA lifeline that are located in areas categorized with direct exposure to wildfire risk on the Functional WUI scale.

Areas in the Functional WUI are those areas where development and building structures may intermix with burnable land cover. Approximately, 6 percent of Key Colony Beach is categorized as having direct exposure to wildfire risk within the Functional WUI. Table B.75-Functional Wildland Urban Interface,City of Key Colony Beach Direct Exposure 17 6% Indirect Exposure 0% Critical Fireshed 2 1% Sources of Ember Load to Buildings 0% Little to No Exposure 233 90% Water 6 2% Source:Southern Wildfire Risk Assessment Figure B-10 depicts the Functional WUI for Key Colony Beach. Figure B-11 depicts Burn Probability based on landscape conditions,percentile weather,historical ignition patterns, and historical prevention and suppression efforts. Fire Intensity Scale,which indicates the potential severity of fire based on fuel loads,topography, and other factors, is depicted in Figure B-12. Majority of the City is located within the Functional WLTI with pockets of direct exposure being spread evenly throughout. Where there is a probability of burning,in the northwestern corner of the City,the burn probability is rated as very low;the remainder of the City has no burn probability associated with it. There are small pockets of high and moderate potential fire intensity,but much of the city has no fire intensity rating. Table B.16 provides building counts and values for critical facilities by FEMA lifeline that are located in areas categorized with direct exposure to wildfire risk on the Functional WUI scale.

MISSION 11411111111111111 SEEN C.11111111111 ASS The City of Key West and the LMS Working Group provided a local inventory of critical facilities and community lifelines,which are a priority for mitigation planning and emergency management. Lifelines are the most fundamental services in the community that,when stabilized, enable all other aspects of society to function. Table C.1 provides a count of critical facilities by FEMA lifeline category in the City of Key West. Figure C-1 shows the locations of all critical facilities in the City of Key West. Table C.2 provides a detailed inventory of the critical facilities in the City of Key West, indicating each facility's FEMA lifeline category, flood zone, 1% annual chance flood depth, sea level rise, storm surge, and wildfire.

Table C.3 details the acreage of Key West's total area by flood zone on the effective DFIRM; it also shows a comparison to the preliminary DFIRM released in December 2019. Slightly over 89 percent of Key West falls within the mapped 1%-annual-chance floodplains; this area would grow to 92.9 percent on the 2019 preliminary maps. The data in this risk assessment is based off FEMA's 2005 DFIRM.

Areas in the Functional WUI are those areas where development and building structures may intermix with burnable land cover. Approximately, 4 percent of Key West is categorized as having direct exposure to wildfire risk within the Functional WUI. Table C.75-Functional Wildland Urban Interface,City of Key West Direct Exposure 142 14%,zo Indirect Exposure 0% Critical Fireshed 460 12% Sources of Ember Load to Buildings 266 7% Little to No Exposure 2781 73% Water 163 4% Source:Southern Wildfire Risk Assessment Figure G11 depicts the Functional WUI for Key West. Figure C-12 depicts Burn Probability based on landscape conditions,percentile weather,historical ignition patterns, and historical prevention and suppression efforts. Fire Intensity Scale,which indicates the potential severity of fire based on fuelloads, topography, and other factors, is depicted in Figure G 13. Functional WUI areas are focused along the outer edges of the City,with the central,downtown area being excluded from the Functional WUI. Where there is a rating for burn probability,mainly in southern and eastern Key West, it is very low; otherwise,much of the city is without a burn probability rating. There are pockets of moderate to high characteristic fire intensity, especially around the outer edges of the City,but a large swath of the City is not rated on the characteristic fire intensity scale. Table C.16 provides building counts and values for critical facilities by FEMA lifeline that are located in areas categorized with direct exposure to wildfire risk on the Functional WUI scale.

ME ���11 ���11 11411111111111111 ASS The City of Layton and the LMS Working Group provided a local inventory of critical facilities and community lifelines,which are a priority for mitigation planning and emergency management. Lifelines are the most fundamental services in the community that,when stabilized, enable all other aspects of society to function. Table D.1 provides a count of critical facilities by FEMA lifeline category in the City of Layton. Figure D-1 shows the locations of all critical facilities in the City of Layton. Table D.2 provides a detailed inventory of the critical facilities in the City of Layton, indicating each facility's FEMA lifeline category, flood zone, 1% annual chance flood depth, sea level rise, storm surge, and wildfire. More information on hazard vulnerability is provided in the hazard profiles.

Table D.3 details the acreage of Layton's total area by flood zone on the effective DFIRM; it also shows a comparison to the preliminary DFIRM released in December 2019. 100 percent of Layton falls within the mapped 1%-annual-chance floodplains; this would remain the same on the 2019 preliminary maps. The data in this risk assessment is based off FEMA's 2005 DFIRM.

ANNEX D:CITY OF LAYTON D.2.4 WILDFIRE Table D.15 summarizes the acreage in the City of Layton that falls within the Functional Wildland Urban Interface(WLTI), categorized into zones that describe the wildfire risk mitigation activities appropriate for each zone. Areas in the Functional WUI are those areas where development and building structures may intermix with burnable land cover. Approximately, 10 percent of the City of Layton is categorized as having direct exposure to wildfire risk within the Functional WiJI.

Figure D-11 depicts Burn Probability based on landscape conditions,percentile weather,historical ignition patterns, and historical prevention and suppression efforts. Fire Intensity Scale,which indicates the potential severity of fire based on fuelloads, topography, and other factors, is depicted in Figure D-12. Almost all of the outer edge of the City of Layton is within the Functional WUI and rated with direct exposure to wildfire. The conservation half of the city is within the Function WUI and rated with primarily sources of ember load to buildings and critical fireshded. Where there is a rating for burn probability,mainly in the eastern half of the City, it is low; otherwise,much of the developed portion of the city is without a burn probability rating. There eastern half of the City has moderate characteristic fire intensity,but the developed half of the City has very few areas with any ratings on the characteristic fire intensity scale. Table D.16 provides building counts and values for critical facilities by FEMA lifeline that are located in areas categorized with direct exposure to wildfire risk on the Functional WUI scale.

ASS ���11411111111111111 The City of Marathon and the LMS Working Group provided a local inventory of critical facilities and community lifelines,which are a priority for mitigation planning and emergency management. Lifelines are the most fundamental services in the community that,when stabilized, enable all other aspects of society to function. Table E.1 provides a count of critical facilities by FEMA lifeline category in the City of Marathon. Figure E-1 shows the locations of all critical facilities in the City of Marathon. Table E.2 provides a detailed inventory of the critical facilities in the City of Marathon, indicating each facility's FEMA lifeline category, flood zone, 1% annual chance flood depth, sea level rise, storm surge, and wildfire.

E2.7 FLOOD Table E.3 details the acreage of Marathon's total area by flood zone on the effective DFIRM; it also shows a comparison to the preliminary DFIRM released in December 2019. 100 percent of Marathon falls within the mapped 1%-annual-chance floodplains; this would drop to 99.6 percent on the 2019 preliminary maps. The data in this risk assessment is based off FEMA's 2005 DFIRM. Figure E-2 reflects the effective mapped flood hazard zones for Marathon while Figure E-3 displays the 2019 preliminary map. °°° Illlllhlllllll IIIIIIIIIIIIIIIIIII ° IIIIIII IIIIIII °°IIIIIII III IIIIII Illlllh°° Effective DFIRM(2005) Preliminary DFIRM(2019) Change from Flood Zone Percent of Percent of Effective Acreage Total(%) Acreage Total(%) (acres) AE 4,857.5 87.6% 4,664.8 84.1% -192.7 VE 686.9 12.4% 860.3 15.5% 173.4 AO 0.0 0.0% 0.0 0.0% 0.0 0.2%Annual Chance Flood 0.3 0.0% 18.4 0.3% 18.1 Hazard Unshaded X 0.0 0.0% 1.3 0.0% 1.3 Open Water 0.0 0.0% 0.0 0.0% 0.0 Total 5,544.7 10 0.0% 5,544.7 10 0.0% 0.0 SFHA Total 59544.4 100.0% 5,525.1 99.6% -19.3 Source:FEMA Effective DFIRM Note:The differences between the effective FIRM and the preliminary FIRM are significant will likely still change.These details are provided here only as a comparison-all further flood analysis is based in the 2005 Effective DFIRM.

ANNEX E:CITY OF MARATHON E.2.4 WILDFIRE Table E.15 summarizes the acreage in the City of Marathon that falls within the Functional Wildland Urban Interface(WLTI), categorized into zones that describe the wildfire risk mitigation activities appropriate for each zone. Areas in the Functional WUI are those areas where development and building structures may intermix with burnable land cover. Approximately, 9 percent of the City of Marathon is categorized as having direct exposure to wildfire risk within the Functional WiJI. Table E.75-Functional Wildlarid Urban Interface,City of Marathon Ago Direct Exposure 507 9% Indirect Exposure 0% Critical Fireshed 17803 33% Sources of Ember Load to Buildings 697 13% Little to No Exposure 2,124 39% Water 265 5% Source:Southern Wildfire Risk Assessment Figure E-10 depicts the Functional WUI for Marathon. Figure E-11 depicts Burn Probability based on landscape conditions,percentile weather,historical ignition patterns, and historical prevention and suppression efforts. Fire Intensity Scale,which indicates the potential severity of fire based on fuel loads, topography, and other factors, is depicted in Figure E-12. Much of the City of Marathon is within the Functional WUI; small areas of direct exposure are found along the outer edge of the City with larger groups of critical ire shed being found on Fat Deer Key, Long Point Key, and Boot Key. Where there is a rating for burn probability, scattered throughout the City, it is low;however,there are some larger groupings of moderate to high burn probability located on the eastern and western sides of the City. There are small areas of higher characteristic fire intensity particularly in northeastern Marathon,but large swaths of the City are not rated on the characteristic fire intensity scale. Areas outside of the Functional WUI are the largest areas rated for characteristic fire intensity. Table E.16 provides building counts and values for critical facilities by FEMA lifeline that are located in areas categorized with direct exposure to wildfire risk on the Functional WUI scale.

ASS ���11411111111111111 The Islamorada Village of Islands and the LMS Working Group provided a local inventory of critical facilities and community lifelines,which are a priority for mitigation planning and emergency management. Lifelines are the most fundamental services in the community that,when stabilized, enable all other aspects of society to function. Table F.I provides a count of critical facilities by FEMA lifeline category in the Islamorada Village of Islands. Figure F-I shows the locations of all critical facilities in Islamorada. Table F.2 provides a detailed inventory of the critical facilities in Islamorada, indicating each facility's FEMA lifeline category, flood zone, I%annual chance flood depth, sea level rise, storm surge, and wildfire. More information on hazard vulnerability is provided in the hazard profiles. °°° Illlllhlllllll IIIIIII °°IIIIIII Illilll liiiiii IIIIIII Illill °i � �II 1111114������������� I°��IIIIIII �°� IIIIIII.

Table F.3 details the acreage of Islamorada's total area by flood zone on the effective DFIRM; it also shows a comparison to the preliminary DFIRM released in December 2019.Nearly 93 percent of Islamorada falls within the mapped 1%-annual-chance floodplains; this would drop to approximately 90 percent on the 2019 preliminary maps. The data in this risk assessment is based off FEMA's 2005 DFIRM. Figure F-2 reflects the effective mapped flood hazard zones for Islamorada while Figure F-3 displays the 2019 preliminary map. °°° Illlllhlllllll IIIIIII IIIIIII IIIIIIIZoIIIIIIIiie,Ao���,,eageIllill IIIIIIIIIIIIIII Effective DFIRM(2005) Preliminary DFIRM(2019) Change from Flood Zone Percent of Percent of Effective Acreage Total(%) Acreage Total(%) (acres) AE 3,412.5 75.7% 3,538.3 78.5% 125.8 VE 755.6 16.8% 503.4 11.2% -252.2 AO 0.0 0.0% 0.0 0.0% 0.0 0.2%Annual 144.1 3.2% 357.0 7.9% 212.9 Chance Flood Hazard Unshaded X 194.4 4.3% 107.9 2.4% -86.5 Open Water 0.0 0.0% 0.0 0.0% 0.0 Total 4,506.6 100.0% 4,506.6 100.0% 0.0 SFHA Total 49168.1 92.5% 49041.8 89.7% -126.3 Source:FEMA Effective DFIRM Note:The differences between the effective FIRM and the preliminary FIRM are significant will likely still change.These details are provided here only as a comparison-all further flood analysis is based in the 2005 Effective DFIRM.

ANNEX F:ISLAMORADA VILLAGE OF ISLANDS F.2.4 WILDFIRE Table F.15 summarizes the acreage in the Islamorada Village of Islands that falls within the Functional Wildland Urban Interface(WLTI), categorized into zones that describe the wildfire risk mitigation activities appropriate for each zone. Areas in the Functional WUI are those areas where development and building structures may intermix with burnable land cover. Approximately, 14 percent of Islamorada is categorized as having direct exposure to wildfire risk within the Functional WiJI.

Figure F-11 depicts Burn Probability based on landscape conditions,percentile weather,historical ignition patterns,and historical prevention and suppression efforts. Fire Intensity Scale,which indicates the potential severity of fire based on fuel loads,topography, and other factors, is depicted in Figure F-12. Much of Islamorada is within the Functional WUI with some small clusters of direct exposure present along the outer edge. Where there is a rating for burn probability, scattered throughout the Village with WUI areas, it is very low; otherwise, much of the city is without a burn probability rating. There are small areas of higher characteristic fire intensity throughout the Village,but large swaths of the Village are not rated on the characteristic fire intensity scale. Table F.16 provides building counts and values for critical facilities by FEMA lifeline that are located in areas categorized with direct exposure to wildfire risk on the Functional WUI scale.

David Stroud and Abby Moore with WSP facilitated the nneeting following the agenda above.David began the presentation with why we Plan in the first Place.David discussed that the Disaster Mitigation ation Act(DMA)of 2000 which is codified i:n CCFR 201.6 requires local govemments,to update their hazard. utrat c,'VyudllxJaLe 1ar,uluarY2O25 wx.a11 s%r ten°,l"�"9�d�i Ili i�� ':;irou lh:;r-°A °t iang# as A 1 III ����ii iiiro C c)wri t WSIII:���� oc�)III III iii t iii a d oiii,''m SU,ategy 3 a u a 2,0 2 APPENDIX B:PLANNING PROCESS DOCUMENTATION mitigation plans every five years,to receive FEMA pre-and post-disaster mitigation Rinding t1irougli the Hazard Mitigation Assistance ftinding programs.David reviewed some trends in disasters including that we now have more frequent and intense hazard events and greater exposure to risk(people,property and critical infrastructure).In 2024 there were 27 billion-dollar disasters.Hazard mitigation is a priority for multiple reasons,including that the cost of doing nothing is too high,many events are predictable and repetitive,loss reduction can be effective,cast-hen eficial,and enviro nine ntall y-sound,there are legal and moral responsibilities to prevent disasters,and there are federal funds,available to support mitigation.The average benefit-cost ratio for federally-funded projects is 6:1. �IID-Z E C"T" V IV W IF V II E��W! David explained that we must follow the DMA planning process and this plan will integrate Conu-n-unity Rating System(CRS)Activity 5 1 lanning steps into the DMA four-plias,e planning process to meet the requirements of both programs.The DMA process provides continued eligibility for initigation.ffinding, guides initigation activities,in a coordinated.and economical manner,integrates hazard mitigation with other planning mechanisms,directs future development in a safe manner,and helps make communities more disaster resistant.The CRS program provides,policy holders,in participating communities with flood insurance discounts,based on the number of CRS p ints the communities earn.The flood insurance preinium reductions,are corninunity-wide. Cory asked if there is an opportunity for communities to improve their CRS rating through this process. David explained that it depends on the number of points each community has.While every point helps the communities,it may not be enough points,to put them over a new rating threshold. WSP will ensure that theupdated local mitigation strategy meets all FEMA planning requirements, coordinates with the natural hazards in the updated State Hazard Mitigation Plan,includes natural and hunian-caused hazards as identified by the LMSWG,incorporates local climate change data and findings, and addresses equitable outcomes. [D[A II'NJ Il'NJ JD Q Abby described the planning process in more detail. Phase 11-Orgianize Resources Phase 1 is already underway.The LMSWG was reconvened with some new members and will be asked to attend four meetings,provide input on risk and capability,update mitigation actions,and review plan drafts.LMS,WG members,especially staff,were,also asked to consider ways to involve the public throughout the planning process.Another priority is to,identify stakeholders that should be invited to participate in the planning process,especially those that may be able to represent u n.derserveld communities and/or vulnerable populations.To maximize CRS credit and support awareness of the plan, 30 outside stakeholders,must be invited to participate and provide input.Lori and David noted the importance of jurisdictional representation at the working group,meetings to,ensure maximum CRS credit. Phase 2-Asse�ss Risks Phase 2 covers,the risk assess Yu.ent,'which includes,the hazard identification,the vulnerability assessment, and the capability assessment.The hazards that were addressed in the previous plan were presented and are as follows,:tropical cyclones,flood,severe storms,(thunderstorm wind,lightning,and hail),tornadoes and waterspouts,sea.level rise and climate change,drought,wildfire,coastal erosion,extreme heal, radiological incident.,and cyber attack.Cory also asked if terror attacks should be included in this,plan. Abby explained that this may be better covered in an emergency operation plan,but that it could be included if the working group wants to include it.David further explained that it's only best to include if there is an associated mitigation action to include in the plan.Cory mentioned that they have received funding for barriers,in the past.Abby noted that the count has until March to decide if they want to include this in the plan. 7 I ic>ciaII Strategy J 1�3 1`11 1�J'a l�,�Y d?0 2 5 cxw a PA��t c a t 11, t ir C,�i ec ), e 2 Y Mo iii,iiii,oe Couiii,ity, oc�)III III itigadoir'l Strategy 3 a r''i u a i��y 2,0 2,6 APPENDIX B:PLANNING PROCESS DOCUMENTATION Mike,noted that the County lias,consi I dered sea walls and asked if this is�something that can be included in the mitigation strategy.Abby confin-ried that it could be included. Phase 3,-Develop a M[figation Strategy Phase 3 involves developing a mitigation strategy by reviewing and updating the plan goals and objectives,evaluating mitigation alternatives,,including existing and new projects,and drafting an action plan with prioritized projects.Abby reviewed different approaches to mitigation,the six FE,MA/CRS mitigation categories,and the count of actions,by category for each jurisdiction in the existing LMS,.In the plan update communities must have at least one action for each natural hazard to meet FEMA requirements and should include a�flood-related action for at least 5 of the 6 mitigation categories to maximize CRS credit,. Heather asked if one initigation action could cover multiple hazards.Abby explained that this is possible but noted that we want to try and address all hazards,especially high and medium risk hazards.Abby also highlighted that actions are only required for natural hazards—FEMA does not evaluate actions for human-cased hazards. Abby also explained that all existing projects included in the previous plan will need a status,update. WSP will send an excel spreadsheet to every jurisdiction to provide updates and comments on their actions. Phase 4-Adoption and I mplementMilon Phase 4 is where the communities must adopt and implement the plan.The communities and LMS,WG Neill meet quarterly to review the action plan and look for funding and opportunities to implement projects.The plan will continue to be updated every five years. S I E D U1 L. (IIII Abby presented a tentative schedule for the planning process,which includes additional LMSWG meetings around April,May,and June.The draft plan is due to FDEM in July.The plan must be approved by FDEM and FEMA and adopted by all communities before the current plan expires,in January 20, . l`J III,'X'T'STEIPS Abby discussed public outreach efforts,which includes public meetings facilitated by WSP,a public survey,and a plan website.Community staff were asked to post outreach on local websites and social media and consider ways to advertise the plan and the survey at community events.Tile plan website used for the previous,plan update will be rebooted and shared once it is available. WSP will work with the County to sched-Lite a public meeting.This meeting will probably be held virtually.WSP will provide publicity language for the survey and public meeting. WSP will be reaching out to jurisdiction representatives to,schedule Community Data Collection Meetings,to discuss,local hazard information,local capabilities,and mitigation action updates.WSP will reach out with date and time options over the next few weeks.Any community staff or stakeholders that can provide useful inforniation are welcome to join the calls. Abby asked the LMSWG to begin reviewing the existing actions and thinking about status updates.They can also begin considering new mitigation actions.The L,MSWG was,also,asked to look for opportunities to support,public engagement and to document any publicity and engagement efforts. 7 I ic>ciaII Strategy J 1�3''11 1�J'a l�Y 21 2 5 cxw a PA��t c a t� 11, t r C'�i ec J �:)' e 3 Y Mo iii-iiii-oe Couiii,ity, WS oc�)III Mitigadoiii,''l SU,ategy 3 a u a 2,0 2,6 ���)E,Ige Lill APPENDIX B:PLANNING PROCESS DOCUMENTATION Moore Nb;nN, il 6 IPM pN 4 PM 1 h8m ,.ulo VM�.

There are four main steps,in the IRA:identify hazards,profile hazard events,inventory assets,and estimate losses.Risk is a combination of a hazard,vulnerability,,and exposure.Each of these factors is evaluated in the,risk assessment process. To update the hazard identification,WS,P reviewed the hazards in the 2023,State Hazard Mitigation Plan and the hazards in the 2021 Monroe County LMS.All existing hazards in the Monroe County LMS were carried forward for re-evaluation.Cory asked if all State:hazards niust be included,and David clarified that hazards in the State plan that aren't relevant to the planning area are not included in the LMS.For example,winter storn,s and earthquakes are not evaluated in the LMS. Looking at FEMA Major Disaster Declarations,,there have been 27 disaster declarations that included Monroe County.Most of these events have been hurricanes and tropical storins.Heather Carruthers asked if this plan includes the mainland portion of Monroe County,as this may explain why the County has received declarations for freezes and fire.David confirmed that it does include the full extent,of Monroe County, David reviewed data,from NCEI Storin Events database,which is,compiled at a,county level and reports hazard events,by type along,with.any reported property damages,crop damages,deaths,injuries,and narrative descriptions,of the event.Reviewing past events from this database provides at least a basic understanding,of the types of events and impacts that can occur in the county. David concluded by listing the hazlards,that were identified for,inclusion in the plan update: Flood Padidlogical Incidents Tropical Cyclones Cyber,Attack SQ,vere Storms&Tornadoes WRdfi're Coastal Erosion Drought Elxtr"enle Heat I a Levei rise Heather Carruthers asked about the omission of earthquake from the hazard list and whether the hazard identification is only retrospective or if we also look forward at what can happen in the ftifure.She noted, having felt are earthquake in Monroe County.David clarified that we are looking at retrospective data as well as,future trends and projections.Ranger added that each hazard profiled will include a hazard specific discussion of impacts of climate change. Cory asked about the inclusion of transportation disruption and provided examples of how the Keys,have experienced disruptions and econoinic losses as,a result of road and bridge closures.WSP will evaluate this,further.

There are 430 identified critical facilities countywide,which have been sununarizied by FENIA.lifeline category.Critical facilities were identified using data from the existing L,MS,updates m community staff collected at the community data meetings,and certain energy,water,wastewater,and government facilities from the communities'Vulnerability Assessments.AJEngetmeyer asked if water systems, include wastewater facilities.Ranger confirmed that it does include wastewater facilities,and the full inventory will be provided so the LMSWG can confirin and add to the inventory if needed. H A,Z A III IID III I IE-S, David presented the Priority Risk Index(PRI),methodology which is used to rate each hazard on a set of standard criteria.This provides an overall risk rating to summarize and rank the risk of each hazard.The preliminary PRI ratings are,shown below: Hazard III`Probab" t Wa I TIm e Spatial ming i Durat'j"on �PRI y Impact M D T Co Scow Extent re Less than 11 week laistiW ErosJon Likely L j rn,i t ed Sr"niall More than,24 hr's or rought Likely Minor Large More than 24 hrs More thain I week Extreme Heat Likely Lir-nited Large More than 24 hrs Less than 11 week Flood Highly I ikely Criticall 11 argie 6 to 12,hours I ess than I week, 'ig L i'ly k e*y L ik 'ted .Va 0'Y rit'c'a I 't1c Sea Level Rise HigNly Likely Critical Large 11 More than 24 hrs More than I week Severe Storms& d jjg y I ely ILI 1 HJgNy Likely Lirnited Moderate Less than 6 hrs Less than 6 hrs Tornadoles Li v L I mit Wildfire Likely Limited Small Less than 6,hirs, Less than 1 week, R'a dogical inch lent!

Cory asked if coastal erosion is based on long-term erosion or impacts from specific storm events,.He noted that erosion is particularly a concern.in Key West around Higgs each and Martello.Alison Higgins agreed that the coastal erosion rating seems low;the individual criteria fit but the hazard,should be rated higher overall.Erosion has also been a major issue in Islarnorada,particularly when storni surge washed across the island in the Matecumbe area.Dan Sabino,asked whether the erosion that occurs,with severe stole s is covered under that hazard. David and Ranger presented summary infolmiation on each of the identified natural hazards.See slides 21-34 for more detail. Flood— Per the effective FIRM data,nearly 72%of the county is in Zone AE and over 22%,is in Zone VE; this is skewed by the large mainland portion of Monroe County and surrounding water area that is included in these acreages.Acreages will be provided by community in the plan which should provide a better picture of flood zone acreage where people live. — There are 3 5 244 buildings located in Zone AE and 2,716 in Zone VE.This is,Just exposure by flood zone.WSP is working on developing loss,estimates,using FEMA's Hazus software.WSP will also evaluate flood exposure and loss estimates using the preliminary FIRM.

Severe Storms&Tornadoes — There are 32 tornadoes reported in NCE,I from 2000-2024,which caused$5.3 million in property damages. — NCEI reports,12 damaging lightning strikes,causing$73k in property damage and 4 injuries,7 hail incidents,with hail tip to 1.75"in diameter,and 53 thunderstorm wind records causing$147k in damages.These events,are likely underreported but illustrate the type of damage that can and has occurred. Wildfire — WUI is,where structures meet undeveloped wildland or vegetative ftiels.An estimated 15%of the county' opulation lives within the critical fire shed,where fire can reach a significant number of buildings within a single burning period.About 1%,of the population lives,in areas of direct exposure, which is where burnable landcover is within 75m.of buildings. — From 2000-2024,FDACS reports 167 fires which burned 186 acres. — Bum probability is moderate to,high in over half of the county,but this is primarily in the mainland. %of the county is not included in bum probability estimates. — Current wildfire is in the Mianii-Dade side of Everglades.Monroe County's focus has been on fire watches,in Big Pine area. — In 20,17,after Irina there were issues with fires in Big Pine. Coastal Erosion — State Critically Eroded Beaches Report indicates 15.02 miles of Florida Key'36.3 miles of beaches are critically eroded.This includes erosion from stornis,wave action,sea level rise,human activity. — Dan Sabino noted there are areas where land around transmission poles eroded.Florida Keys Electric Coop also has,this issue and has moved poles with HMGP,funding. — Tom Harding indicated that a significant amount of work has been done at Sea Oats,Beach.Ranger acknowledged that ongoing work will be addressed in the hazard profile. Drought From 2000-2024 Monroe County was in drought 42%of the time,mostly in abnormally dry conditions.There is about a 10%chance of drought in any given week based on past occurrences. Extreme Heat — In 20,23,more people in the US died from Beat-related illness than arly year on record.Certain populations have higher vulnerability.Climate change is,expected to make extreme,heat worse across the southeast. — Highest temperature on record for Key West is 96 OF,which occurred,in July and Aug�List 2024.

Ranger indicated that we need to hold community data collection meetings,with Mo�nroe County and Marathon.Representatives froin these cominunities are asked to let WSP know availability for a meeting. We need to provide a count of repetitive loss,properties by Jurisdiction and indicate tile number that are residential vs.conmiercial.We would also like to incorporate mapping of repetitive loss,areas into the flood hazard profile.WSP can use FE.MA open data for repetitive loss property counts or communities can provide this summarized data if they already have it.WSP cannot handle,raw repetitive loss data froin FEMA unless we are in with third-party access oil your data sharing agreement.WSP will provide request forms to each eon inunity which you can submit to.FEMA if you wish to request updated data to share with us.

Abby ug,ge ted communities,think about the following changes are.d updates,over the past five years when updating;their capability results. — Additional finding — New r updated plains — New staff — Updated flood or open space regulations — New emergency warning systems or strategies — Completed mitigation projects Cory mentioned that open space management plans are difficult for all jurisdictions to,complete and asked)if this would reflect negatively on the municipalities.Abby said that it doesn't,and they can remove whatever isn't relevant to the comniu n.ities,The committee will discuss this topic further and report their decision to,WSP INew FEMA Requirements Abby briefly noted that there is a new FEMA requirement for substantial damage estimate procedures. The plan must include information on)now participating communities nities use the NFIP to reduce risk after a disaster through substantial damage and substantial improvement SI /Sl procedures.Abby noted that WSP has net yet received all the information on the community's unit 's post event procedures.These procedures don't have to be reported in detail,but the plan must document that these post event procedures exist within the community.

The committee asked if it was possible to add mitigation actions n post plan approval.Abby responded that it is possible but will require a plan amendment which can be a lengthy process,and it is,much easier t turn in the mitigation actions new.Additionally,Abby noted that mitigation actions with pending or u n.known ftunding;sources should still be included in the plan,. mitigation strategy is meant to,reduce the impact of hazards on existing,development and ensure future, development occurs in a way that minimizes vulnerability. ,Goals&Objectives Ranger reviewed the existing goals and objectives from the previous,plan update and discussed potential revisions to implement with the conu.-nittee for the current plan update.These revisions can be found on slides 17 and 18 of the presentation,No fuurther comments or revisions were recommended by the FIMPC. IMlitii ation Action IRequirements Ranger informed the conuiiittee that FEMA requires at least one mitigation n action for each identified. hazard in the plan update.All mitigation actions will need to be organized into the categories found below.Abby noted that to maximize CRS credit they should include flood-related actions in at least five of the six mitigation categories. l, Prevention Gland development plans&zoning,freeboard requirements,) a.

P II OJ II{r + V IIE R V II \A/ David explained that we must follow tihe DMA planning process and this plan.will Integrate "onu i-Linity Rating System(CRS)Activity 5 10 p,lanning steps into the DMA four-phase planning process to meet:the requirements of both programs.The DMA process provides continued eligibility for mitigation frwunding, guides snitigationn activities in a coordinated and economical manner,integrates hazard mitigation. with other planning mechanisms,directs future development in a safe manner,and helps make communities more disaster resistant.The CRS program provides policy holders in part icipating communities with flood,insuurance discounts,based on the number of CRS points the connnnuunities earn.The flood insurance premium reductions,are coiuirnnnuunity-wide. ,40111"tllf"a,:Y4 4,c,xJwii'Ay, I I a.i 10 lit ll(,,Jatlllrllr"stiriat (,,wjy Jiiirl°I141",i1Y 2 2b oc,fll I'"A1t11iqadoun'UralIe y—Pu,dahc ,Aeiet111rc 41 III ����III IIm C o wI WSIII IIL..�.oc�)III III III t iii a d oIII°m SU,ategy 3 z III°mu a Iy 2,0 2 IIC)'zge III''''''' '.7 APPENDIX B:PLANNING PROCESS DOCUMENTATION WSP will ensure that the updated local initigation strategy meets all FEMA planning requirements, coordinates with the natural hazards in the updated State Hazard Mitigation Plan,includes natural and huinan-caused hazards as identified by the LMSWG,incorporates local climate change data and findings, and addresses equitable outcomes. IIE-S S Abby described the planning process in more detail. Phase 11-Organize Reslources, Phase I is already underway.The LMSWG was reconvened with soine new members and will be asked to attend meetings,provide input on risk and capability,update mitigation actions,and review plan drafts. The planning team will also,identify stakeholders that should be invited to participate in the planning process,especially those that may be able to,represent underserved comin-unitiles and/or vulnerable populations..Abby asked attendees to suggest any grollips,people,or stakeholders,that should be included. Phase 2-Asse�ss R'I'sks Phase 2 covers,the risk assessment,which includes,the hazard identification,the vulnerability assessment., and the capability assessment.The hazards that were addressed in the previous plan were presented and are as follows:tropical cyclones,flood,severe storins,(thunderstorm wind,lightning,and hail),tornadoes and waterspouts,sea.level rise and climate change,drought,wildfire,coastal erosion,extreme heal, radiological incident,,and caber attack. Phase 3,-Dievelop a M[figation Strategy Phase 3 involves developing a.mitigation strategy by reviewing and updating the plan goals and objectives,evaluating mitigation alternatives,,including existing and new projects,and drafting an action plan with prioritized projects.Abby reviewed different approaches to mitigation,the six FE,MA/CRS mitigation categories:property protection,stnictural projects,emergency services,natural resource protection,and public education.In the plan update communities must have at least one action for each natural hazard to meet FEMA requirements and should include a flood-related action for at least 5 of the 6 mitigation categories to maximize CRS credit. Phase 4-Adapflion and I rnplementaltion Phase 4 is where the conununities must adopt and implement the plan.The communities and LMS,WG will meet quarterly to,review the action plan and look for Rinding and opportunities to implement projects.The plan will continue to be updated every five years,. � �IHEDUU�E"IID Q E-C"T S(I'�I Abby presented a tentative schedule for the planning process,which includes additional LMSWG meetings around April,May,and June.The draft plan is due to FDEM in Judy,The plan must be approved by FDEM and FEMA and adopted by all communities,before the current plan expires,in January 20, . I1111J VF SIT IIV 11P S Abby discussed public outreach efforts which include public meetings facilitated by WSP,a public survey,and a plan web site.The plan web site will host the survey,meeting materials,and draft plans,for review when made available. 7L�I ic>ciaII Strategy J 1�3''11 1G J'a�Y 21 0 2 5 'I cx�a PA��t c at ir a S t ii a t em­p i ii ir elet��ira g;14 1 e 2 J Mo iii,iiii,oe Couiii,ity, oc�)III III itigadoiii,''l SU,a tog y 3 a u a 2,0 2,6 f:�)age APPENDIX B:PLANNING PROCESS DOCUMENTATION Partild panift iim®;Oil x ......................

Other agencies and organizations must be contacted to determine if they have studies,plans and information pertinent to the Hazard Mitigation Plan,to determine if their programs or initiatives may affect the community's program,and to see if they could support the community's efforts. To incorporate stakeholder input into the plan,a variety of stakeholders were identified by the LMSWG and sent an email inviting them to attend a public meeting,review the draft plan,and provide feedback and comments. The coordination letter sent via email is provided below.A list of stakeholders detailing their involvement is provided in Table B.3.

As part of the process of developing the mitigation action plans found in Section 7,the LMSWG reviewed and considered a comprehensive range of mitigation options before selecting the actions identified for implementation. This section summarizes the full range of mitigation measures evaluated and considered by the LMSWG, including a review of the categories of mitigation measures outlined in the 2017 CRS Coordinator's Manual, a discussion of current local implementation and CRS credits earned for those measures, and a list of the specific mitigation projects considered and recommended for implementation. Mitigation alternatives identified for implementation by the LMSWG were evaluated and prioritized using the criteria discussed in Section 6 of this plan. ....................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................... ���������� CA �����������������������������M�S�II����������� ����������� �������������������������� ������������������������ ������������������������������ ������������������������������ �������������������������� IIIIIIIIIIIIIIIIIIIII ������������������������� IIIIIIIIIIIIIIII C. uuuuuuu uuuuuuu uumum III uuuuuuu uuuuum uuuuuu°°°um uuuuuuu uuuuum uuuuuumuumum uuuuuuu Vo, uuuuuuuuuuuum uuuuuuuuuuuum uuuuuuu uuuuuuuuuuuuu uuuuuuuu uuuuuuuuuuuum uuuuuuuuuuuum uuuuuum Once it was determined which flood hazards warranted the development of specific mitigation actions, the LMSWG analyzed viable mitigation options that supported the identified goals and objectives. The LMSWG was provided with the following list of mitigation categories which are utilized as part of the CRS planning process. — Prevention — Property Protection — Natural Resource Protection — Structural Projects — Emergency Services — Public Education and Awareness Action ideas within each of these categories were discussed and considered for inclusion in the plan. The LMSWG was encouraged to select actions to pursue within most if not all of these categories so as to develop a comprehensive approach to hazard mitigation. .......................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................

S Preventative measures are designed to keep a problem- such as flooding- from occurring or from getting worse. The objective of preventative measures is to ensure that future development is not exposed to damage and does not cause an increase in damages to other properties. Building, zoning,planning and code enforcement offices usually administer preventative measures. Some examples of types of preventative measures include: — Building codes — Zoning ordinance — Comprehensive or land use plan — Open space preservation — Floodplain regulations — Subdivision regulations Stormwater management regulations IJ Building codes provide one of the best methods for addressing natural hazards. When properly designed and constructed according to code,the average building can withstand many of the impacts of natural hazards. Hazard protection standards for all new and improved or repaired buildings can be incorporated into the local building code. Building codes can ensure that the first floors of new buildings are constructed to be higher than the elevation of the 100-year flood(the flood that is expected to have a one percent chance of occurring in any given year). This is shown in Figure C.1. Just as important as having code standards is the enforcement of the code. Adequate inspections are needed during the course of construction to ensure that the builder understands the requirements and is following them.

Any building or structure that falls within the scope of the IBC that is proposed in a flood hazard area is to be designed in accordance with ASCE 24. Freeboard is required as a function of the nature of occupancy and the flood zone. Dwellings and most other buildings have 1-foot of freeboard; certain essential facilities have 2-3 feet; only agricultural facilities,temporary facilities and minor storage facilities are allowed to have their lowest floors at the BFE. Building codes provide guidance on how to build in hazardous areas. Planning and zoning activities direct development away from these areas,particularly floodplains and wetlands. They do this by designating land uses that are compatible with the natural conditions of land that is prone to flooding, such as open space or recreation. Keeping the floodplain and other hazardous areas open and free from development is the best approach to preventing damage to new developments. Open space can be maintained in agricultural use or can serve as parks, greenway corridors and golf courses. Comprehensive and capital improvement plans should identify areas to be preserved by acquisition and other means, such as purchasing an easement. With an easement,the owner is free to develop and use private property,but property taxes are reduced or a payment is made to the owner if the owner agrees to not build on the part set aside in the easement. Although there are some federal programs that can help acquire or reserve open lands, open space lands and easements do not always have to be purchased. Developers can be encouraged to dedicate park land and required to dedicate easements for drainage and maintenance purposes.

Zoning can ensure compatibility of land use with the land's level of suitability for development. Planning and zoning activities can also provide benefits by allowing developers more flexibility in arranging improvements on a parcel of land through the planned development approach. Zoning regulations describe what type of land use and specific activities are permitted in each district, and how to regulate how buildings, signs, parking, and other construction may be placed on a lot. Zoning regulations also provide procedures for rezoning and other planning applications. The zoning map and zoning regulations provide properties with certain rights to development. a p 3 A Flood Damage Prevention Ordinance sets development standards for Special Flood Hazard Areas (SFHAs). Communities participating in the National Flood Insurance Program(NFIP) are required to adopt a flood damage prevention ordinance that meets at least the minimum standards of the NFIP; however, a community can incorporate higher standards for increased protection. For example, communities can adopt higher regulatory freeboard requirements, cumulative substantial damage definitions, fill restrictions, and other standards. Another important consideration in floodplain regulations is the protection of natural and beneficial functions and the preservation of natural barriers such as vegetation. Vegetation along a stream bank is extremely beneficial for the health of the stream. Trees and other plants have an extensive root system that strengthen stream banks and help prevent erosion. Vegetation that has sprouted up near streams should remain undisturbed unless removing it will significantly reduce a threat of flooding or further destruction of the stream channel. Stormwater runoff is increased when natural ground cover is replaced by urban development. Development in the watershed that drains to a river can aggravate downstream flooding, overload the community's drainage system, cause erosion, and impair water quality. There are three ways to prevent flooding problems caused by stormwater runoff: Regulating development in the floodplain to ensure that it will be protected from flooding and that it won't divert floodwaters onto other properties; Regulating all development to ensure that the post-development peak runoff will not be greater than it was under pre-development conditions; and Set construction standards so buildings are protected from shallow water. Zoning and comprehensive planning can work together to reduce future flood losses by directing development away from hazard prone areas. Creating or maintaining open space is the primary way to reduce future flood losses. Planning for open space must also be supplemented with development regulations to ensure that stormwater runoff is managed and that development is protected from flooding. Enforcement of the flood damage prevention ordinance and the flood protection elevation requirement provides an extra level of protection for buildings constructed in the planning area. Stormwater management and the requirement that post-development runoff cannot exceed pre- development conditions is one way to prevent future flood losses. Retention and detention requirements also help to reduce future flood losses.

It provides credit in two ways: points are awarded based on the community's Building Code Effectiveness Grading Schedule (BCEGS) classification and points are awarded for adopting the International Code series. In North Carolina, communities are limited by the State Building Code Council which has not implemented the most current version of the International Building Code. CRS credits are available for regulations that encourage developers to preserve floodplains or other hazardous areas away from development. There is no credit for a plan, only for the enforceable regulations that are adopted pursuant to a plan. Communities in Monroe County could receive credit for Activity 430—Higher Regulatory Standards and for Activity 420—Open Space Preservation for preserving parcels within the SFHA as open space. Preserving flood prone areas as open space is one of the highest priorities of the Community Rating System. The credits in the 2017 manual have doubled for OSP (Open Space Preservation). The participating communities could also receive credit for Activity 450 —Stormwater Management for enforcing regulations for stormwater management and soil and erosion control.

Property protection measures are used to modify buildings or property subject to damage. Property protection measures fall under three approaches: — Modify the site to keep the hazard from reaching the building; — Modify the building(retrofit) so it can withstand the impacts of the hazard; and — Insure the property to provide financial relief after the damage occurs.

Careful Berg design is needed so as not to create flooding or rm alI Ibarriers can be effelctive against:shalI ow f1 o,odin . drainage problems on neighboring properties. Depending on how porous the ground is, if floodwaters will stay up for more than an hour or two, the design needs to account for leaks, seepage of water underneath, and rainwater that will fall inside the perimeter. This is usually done with a sump or drain to collect the internal groundwater and surface water and a pump and pipe to pump the internal drainage over the barrier. Barriers can only be built so high. They can be overtopped by a flood higher than expected. Barriers made of earth are susceptible to erosion from rain and floodwaters if not properly sloped, covered with grass, and properly maintained. ....................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................... RELOCATION Moving a building out of a flood prone area to higher ground is the surest and safest way to protect it from flooding. While almost any building can be moved,the cost increases for heavier structures, such as those with exterior brick and stone walls, and for large or irregularly shaped buildings. Relocation is also preferred for large lots that include buildable areas outside the floodplain or where the owner has a new flood-free lot(or portion of the existing lot) available.

JILDING ELEVA Raising a building above the flood level can be almost as effective as moving it out of the floodplain. Water flows under the building, causing little or no damage to the structure or its contents. Raising a building above the flood level is cheaper than moving it and can be less disruptive to a neighborhood. Elevation has proven to be an acceptable and reasonable means of complying with floodplain regulations that require new, substantially improved, and substantially damaged buildings to be elevated above the base flood elevation. DEMOLITION n`' IWJ Some buildings, especially heavily damaged or repetitively flooded ones are not worth the expense to protect them from future damages. It is cheaper to � w demolish them and either replace them with new, flood protected structures, or relocate the occupants to a safer site. Demolition is also appropriate for buildings that are g ,:..„ �Ju4ui o,�oIDJ'NWuN o^P,ir,�rvjNd4ui4��1V, difficult to move—such as larger, slab foundation or rua - masonry structures and for dilapidated structures that are not cost-beneficial to protect. Demollshing a repetitively flooded home PILOT RECONSTRUC O If a building is not in good shape, elevating it may not be worthwhile or it may even be dangerous. An alternative is to demolish the structure and build a new one on the site that meets or exceeds all flood protection codes. FEMA funding programs refer to this approach as "pilot reconstruction." It is still a pilot program, and not a regularly funded option. Certain rules must be followed to qualify for federal funds for pilot reconstruction. ....................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................... RETROFITTING An alternative to keeping the hazard away from a building is to modify or retrofit the site or building to minimize or prevent damage. There are a variety of techniques to do this, as described below. Dry Floodproofing Dry floodproofing means making all areas below the flood protection level watertight. Walls are coated with waterproofing compounds or plastic sheeting. Openings, such as doors,windows and vents, are closed, either permanently,with removable shields, or with sandbags. Dry floodproofing of new and existing nonresidential buildings in the regulatory floodplain is permitted under state,FEMA and local regulations. Dry floodproofing of existing residential buildings in the floodplain is also permitted as long as the building is not substantially damaged or being substantially improved. Owners of buildings located outside the regulatory floodplain can always use dry floodproofing techniques. Dry floodproofing is only effective for shallow flooding, such as repetitive drainage problems. It does not protect from the deep flooding along lakes and larger rivers caused by hurricanes or other storms. Wet Floodproofing The alternative to dry floodproofing is wet floodproofing: water is let in and everything that could be damaged by a flood is removed or elevated above the flood level. Structural components below the flood level are replaced with materials that are not subject to water damage. For example, concrete block walls IIP ����iii iiiro courity, IIL..�.ou III III iii t iii ad aii°m Strategy a iiir.''m u a iii�� 2 2, APPENDIX Q MITIGATION ALTERNATIVES are used instead of wooden studs and gypsum wallboard. The furnace, water heater and laundry facilities are permanently relocated to a higher floor. Where the flooding is not deep,these appliances can be raised on blocks or platforms. Technically, insurance does not mitigate damage caused by a natural hazard. However, it does help the owner repair,rebuild, and hopefully afford to incorporate some of the other property protection measures in the process. Insurance offers the advantage of protecting the property, so long as the policy is in force, without requiring human intervention for the measure to work. Private Property Although most homeowner's insurance policies do not cover a property for flood damage, an owner can insure a building for damage by surface flooding through the NFIP. Flood insurance coverage is provided for buildings and their contents damaged by a"general condition of surface flooding" in the area. Most people purchase flood insurance because it is required by the bank when they get a mortgage or home improvement loan. Usually these policies just cover the building's structure and not the contents. Contents coverage can be purchased separately. Renters can buy contents coverage, even if the owner does not buy structural coverage on the building. Most people don't realize that there is a 30-day waiting period to purchase a flood insurance policy and there are limits on coverage. Public Property Governments can purchase commercial insurance policies. Larger local governments often self-insure and absorb the cost of damage to one facility,but if many properties are exposed to damage, self- insurance can drain the government's budget. Communities cannot expect federal disaster assistance to make up the difference after a flood. The CRS provides the most credit points for acquisition and relocation under Activity 520,because this measure permanently removes insurable buildings from the floodplain. Communities in Monroe County could receive credit for Activity 520—Acquisition and Relocation, for acquiring and relocating buildings from the SFHA. The LMSWG recommended that communities pursue the purchase buildings which are subject to flood damage in order to return this land to open space. The CRS also credits barriers and elevating existing buildings under Activity 530. The credit for Activity 530 is based on the combination of flood protection techniques used and the level of flood protection provided. Points are calculated for each protected building. Bonus points are provided for the protection of repetitive loss buildings and critical facilities. Communities could receive credit for Activity 360— Flood Protection Assistance by providing advice and assistance to homeowners who may want to flood proof their home or business. Advice is provided both on property protection techniques and on financial assistance programs to help fund mitigation. Flood insurance information for each community is provided in Section 5 and in greater detail in each community's annex. There is no credit for purchasing flood insurance,but the CRS does provide credit for local public information programs that, among other topics, explain flood insurance to property owners. The CRS also reduces the premiums for those people who do buy NFIP coverage. Communities in Monroe County could receive credit for Activity 330—Outreach Projects. Property protection mitigation options considered by the LMSWG are described below.

Resource protection activities are generally aimed at preserving(or in some cases restoring)natural areas. These activities enable the naturally beneficial functions of fields, floodplains,wetlands, and other natural lands to operate more effectively. Natural and beneficial functions of watersheds, floodplains and wetlands include: — Reduction in runoff from rainwater and stormwater in pervious areas — Infiltration that absorbs overland flood flow — Removal and filtering of excess nutrients,pollutants and sediments — Storage of floodwaters — Absorption of flood energy and reduction in flood scour — Water quality improvement — Groundwater recharge — Habitat for flora and fauna — Recreational and aesthetic opportunities As development occurs, many of the above benefits can be achieved through regulatory steps for protecting natural areas or natural functions. This section covers the resource protection programs and standards that can help mitigate the impact of natural hazards, while they improve the overall environment. Six areas were reviewed: �� �Fh II 'Nuu — Wetland protection — Erosion and sedimentation control — Stream/River restoration — Best management practices — Dumping regulations — Farmland protection Wetlands are often found in floodplains and topographically depressed areas of a watershed. Many wetlands receive and store floodwaters, thus slowing and reducing downstream flows. They also serve as IIIAarvroe Courity,III:III III: III .III ill .iii iii ..lii ii iii III IIL...ou III III iii t iii atiii aii°m Strategy 3 a iiir.m u a iii. IIC: g e APPENDIX Q MITIGATION ALTERNATIVES a natural filter,which helps to improve water quality, and they provide habitat for many species of fish, wildlife and plants. Farmlands and construction sites typically contain large areas of bare exposed soil. Surface water runoff can erode soil from these sites, sending sediment into downstream waterways. Erosion also occurs along stream banks and shorelines as the volume and velocity of flow or wave action destabilize and wash away the soil. Sediment suspended in the water tends to settle out where flowing water slows down. This can clog storm drains, drain tiles, culverts and ditches and reduce the water transport and storage capacity of river and stream channels, lakes and wetlands. There are two principal strategies to address these problems: minimize erosion and control sedimentation. Techniques to minimize erosion include phased construction,minimal land clearing, and stabilizing bare ground as soon as possible with vegetation and other soil stabilizing practices. �. There is a growing movement that has several names, such as "stream conservation," "bioengineering," or "riparian corridor restoration." The objective of these approaches is to return streams, stream banks and adjacent land to a more natural condition,including the natural meanders. Another term is "ecological restoration," which restores native indigenous plants and animals to an area. A key component of these efforts is to use appropriate native plantings along the banks that resist erosion. This may involve retrofitting the shoreline with willow cuttings,wetland plants, or rolls of landscape material covered with a natural fabric that decomposes after the banks are stabilized with plant roots. In all,restoring the right vegetation to a stream has the following advantages: — Reduces the amount of sediment and pollutants entering the water — Enhances aquatic habitat by cooling water temperature — Provides food and shelter for both aquatic and terrestrial wildlife — Can reduce flood damage by slowing the velocity of water — Increases the beauty of the land and its property value — Prevents property loss due to erosion — Provides recreational opportunities, such as hunting, fishing and bird watching — Reduces long-term maintenance costs Communities are required by state and federal regulations to monitor storm water drainage outfalls and control storm water runoff. Point source pollutants come from pipes such as the outfall of a municipal wastewater treatment plant. They are regulated by the US EPA. Nonpoint source pollutants come from non-specific locations and harder to regulate. Examples of nonpoint source pollutants are lawn fertilizers,pesticides, other chemicals, animal wastes, oils from street surfaces and industrial areas, and sediment from agriculture, construction,mining and forestry. These pollutants are washed off the ground's surface by stormwater and flushed into receiving storm sewers, ditches and streams. The term "best management practices" (BMPs)refers to design, construction and maintenance practices and criteria that minimize the impact of stormwater runoff rates and volumes,prevent erosion,protect natural resources and capture nonpoint source pollutants (including sediment). They can prevent increases in downstream flooding by attenuating runoff and enhancing infiltration of stormwater. They III\4arvroe courity,III:III III: III .III ill .iii iii ..lii ii iii III IIL...ou III III iii t iii atiii aii°m Strategy 3 a iiir.m u a i a IIC: Mm c i APPENDIX Q MITIGATION ALTERNATIVES also minimize water quality degradation,preserve beneficial natural features onsite,maintain natural base flows,minimize habitat loss, and provide multiple usages of drainage and storage facilities. BMPs usually address pollutants that are liquids or are suspended in water that are washed into a lake or stream. Dumping regulations address solid matter, such as shopping carts, appliances and landscape waste that can be accidentally or intentionally thrown into channels or wetlands. Such materials may not pollute the water, but they can obstruct even low flows and reduce the channels' and wetlands' abilities to convey or clean stormwater. Many cities have nuisance ordinances that prohibit dumping garbage or other"objectionable waste" on public or private property. Waterway dumping regulations need to also apply to "non-objectionable" materials, such as grass clippings or tree branches,which can kill ground cover or cause obstructions in channels. Regular inspections to catch violations should be scheduled. Many people do not realize the consequences of their actions. They may, for example, fill in the ditch in their front yard without realizing that is needed to drain street runoff. They may not understand how re- grading their yard, filling a wetland, or discarding leaves or branches in a watercourse can cause a problem to themselves and others. Therefore, a dumping enforcement program should include public information materials that explain the reasons for the rules as well as the penalties. Farmland protection is an important piece of comprehensive planning and zoning throughout the United States. The purpose of farmland protection is to provide mechanisms for prime,unique, or important agricultural land to remain as such, and to be protected from conversion to nonagricultural uses. Frequently, farm owners sell their land to residential or commercial developers and the property is converted to non-agricultural land uses. With development comes more buildings, roads and other infrastructure. Urban sprawl occurs,which can lead to additional stormwater runoff and emergency management difficulties. Farms on the edge of cities are often appraised based on the price they could be sold for to urban developers. This may drive farmers to sell to developers because their marginal farm operations cannot afford to be taxed as urban land. The Farmland Protection Program in the United States Department of Agriculture's 2002 Farm Bill (Part 519) allows for funds to go to state, tribal, and local governments as well as nonprofit organizations to help purchase easements on agricultural land to protect against the development of the land. There is credit for preserving open space in its natural condition or restored to a state approximating its natural condition. The credit is based on the percentage of the floodplain that can be documented as wetlands protected from development by ownership or local regulations. Communities in Monroe County could receive credit for Activity 420—Open Space Preservation for preserving a portion of the SFHA as open space. Additionally, credit is available for Activity 540—Drainage System Maintenance. Having a portion of the drainage system inspected regularly throughout the year and maintenance performed as needed would earn a community credit. Communities could also get credit under this activity for providing a listing of problem sites that are inspected more frequently, and for implementing an ongoing Capital Improvements Program.

Emergency services measures protect people during and after a disaster. A good emergency management program addresses all hazards, and it involves all local government departments. This section reviews emergency services measures following a chronological order of responding to an emergency. It starts with identifying an impending problem(threat recognition) and continues through post-disaster activities. I4-011 The first step in responding to a flood is to know when weather conditions are such that an event could occur. With a proper and timely threat recognition system, adequate warnings can be disseminated. The National Weather Service(NWS)is the prime agency for detecting meteorological threats. Severe weather warnings are transmitted through NOAA's Weather Radio System. Local emergency managers can then provide more site-specific and timely recognition after the Weather Service issues a watch or a warning. A flood threat recognition system predicts the time and height of a flood crest. This can be done by measuring rainfall, soil moisture, and stream flows upstream of the community and calculating the subsequent flood levels. On smaller rivers and streams, locally established rainfall and river gauges are needed to establish a flood threat recognition system. The NWS may issue a"flash flood watch." This is issued to indicate current or developing hydrologic conditions that are favorable for flash flooding in and close to the watch area, but the occurrence is neither certain nor imminent. These events are so localized and so rapid that a "flash flood warning"may not be issued, especially if no remote threat recognition equipment is available. In the absence of a gauging system on small streams,the best threat recognition system is to have local personnel monitor rainfall and stream conditions. While specific flood crests and times will not be predicted, this approach will provide advance notice of potential local or flash flooding.

More people can implement protection measures if warnings are early and include specific detail. The NWS issues notices to the public using two levels of notification: — Watch: conditions are right for flooding,thunderstorms, tornadoes or winter storms. — Warning: a flood,tornado, etc.,has started or been observed. A more specific warning may be disseminated by the community in a variety of ways. The following are the more common methods: — CodeRED countywide mass telephone emergency communication system — Commercial or public radio or TV stations — The Weather Channel — Cable TV emergency news inserts — Telephone trees/mass telephone notification — NOAA Weather Radio — Tone activated receivers in key facilities — Outdoor warning sirens — Sirens on public safety vehicles — Door-to-door contact — Mobile public address systems — Email notifications Just as important as issuing a warning is telling people what to do in case of an emergency. A warning program should include a public information component. The National Weather Service(NWS) established the StormReady program to help local governments improve the timeliness and cl effectiveness of hazardous weather-related warnings for the public. To 4?1ormRea be officiallyStormRead a community must: Y Y — Establish a 24-hour warning point and emergency operations center — Have more than one way to receive severe weather warnings and forecasts and to alert the public — Create a system that monitors weather conditions locally — Promote the importance of public readiness through community seminars — Develop a formal hazardous weather plan,which includes training severe weather spotters and holding emergency exercises Being designated a NWS StormReady community is a good measure of a community's emergency warning program for weather hazards. S The protection of life and property is the most important task of emergency responders. Concurrent with threat recognition and issuing warnings, a community should respond with actions that can prevent or reduce damage and injuries. Typical actions and responding parties include the following: iii iiiro C(D U i1 ty, WSIII: IIM t.1 III ill ,iii�iii ..iii ii iii III IIL...ou III III ii t iii atiii ar''i Strategy a iii*.m t 02,6 IIC:a Cml APPENDIX Q MITIGATION ALTERNATIVES — Activating the emergency operations center(emergency preparedness) — Closing streets or bridges (police or public works) — Shutting off power to threatened areas (utility company) — Passing out sand and sandbags (public works) — Holding children at school or releasing children from school(school superintendent) — Opening evacuation shelters (the American Red Cross) — Monitoring water levels (public works) — Establishing security and other protection measures (police) An emergency action plan ensures that all bases are covered and that the response activities are appropriate for the expected threat. These plans are developed in coordination with the agencies or offices that are given various responsibilities. Emergency response plans should be updated annually to keep contact names and telephone numbers current and to ensure that supplies and equipment that will be needed are still available. They should be critiqued and revised after disasters and exercises to take advantage of the lessons learned and of changing conditions. The end result is a coordinated effort implemented by people who have experience working together so that available resources will be used in the most efficient manner possible. There are six key components to a successful evacuation: — Adequate warning — Adequate routes — Proper timing to ensure the routes are clear — Traffic control — Knowledgeable travelers — Care for special populations (e.g., disabled persons,prisoners,hospital patients, schoolchildren) Those who cannot get out of harm's way need shelter. Typically,the American Red Cross will staff a shelter and ensure that there is adequate food,bedding, and wash facilities. Shelter management is a specialized skill. Managers must deal with problems like scared children, families that want to bring in their pets, and the potential for an overcrowded facility. ...............OCA��............... �M ��q 0 /C S C Flash flood warnings are issued by National Weather Service Offices, which have the local and county warning responsibility. Flood warnings are forecasts of coming floods, are distributed to the public by the NOAA Weather Radio, commercial radio and television, and through local emergency agencies. The warning message tells the expected degree of flooding,the affected river,when and where flooding will begin, and the expected maximum river level at specific forecast points during flood crest. Communities in Monroe County could receive credit for Activity 610—Flood Warning Program for maintaining a program that provides timely identification of impending flood threats, disseminates warnings to appropriate floodplain residents, and coordinates flood response activities. Community Rating System credits are based on the number and types of warning media that can reach the community's flood prone population. Depending on the location, communities can receive credit for the telephone calling system and more credits for additional measures, like telephone trees. Being designated as a StormReady community also provides additional credits.

C.2,5 S TR Lii, Four general types of flood control projects are reviewed here: levees, reservoirs, diversions, and dredging. These projects have three advantages not provided by other mitigation measures: — They can stop most flooding,protecting streets and landscaping in addition to buildings. — Many projects can be built without disrupting citizens'homes and businesses. — They are constructed and maintained by a government agency, a more dependable long-term management arrangement than depending on many individual private property owners. However, as shown below, structural measures also have shortcomings. The appropriateness of using flood control depends on individual project area circumstances. Advantages — They may provide the greatest amount of protection for land area used — Because of land limitations,they may be the only practical solution in some circumstances — They can incorporate other benefits into structural project design, such as water supply and recreational uses — Regional detention may be more cost-efficient and effective than requiring numerous small detention basins Disadvantages IIIAarvroe Courity,III:III III: III .III ill .iii iii ..lii ii iii III IIL...ou III III iii t iii atiii aii°m Strategy 3 a iiir.m u a iii.

Levees and floodwalls confine water to the stream channel by raising its banks. They must be well designed to account for large floods,underground seepage,pumping of internal drainage, and erosion and scour. Reservoirs reduce flooding by temporarily storing i Sri r�rl ri �)19f%JJJ' �� flood waters behind dams or in storage or detention basins. Reservoirs lower flood heights by holding back or detaining runoff before it can flow l r ivli Flo �f Ytt V O downstream.

Flood control reservoirs are most commonly built for one of two purposes. Large reservoirs are constructed to protect property from existing flood problems. Smaller reservoirs, or detention basins, are built to protect property from the stormwater runoff impacts of new development. A diversion is a new channel that sends floodwaters to a different location, thereby reducing flooding along an existing watercourse. Diversions can be surface channels, overflow weirs, or tunnels. During normal flows, the water stays in the old channel. During floods,the floodwaters spill over to the diversion channel or tunnel,which carries the excess water to a receiving lake or river. ...............OCA��........... �M ��q 0 /C S C Structural flood control projects that provide at least 100-year flood protection and that result in revisions to the Flood Insurance Rate Map are not credited by the CRS so as not to duplicate the larger premium reduction provided by removing properties from the mapped floodplain. Other flood control projects can be accepted by offering a 25-year flood protection.

Outreach projects are the first step in the process of orienting property owners to the hazards they face and to the concept of property protection. They are designed to encourage people to seek out more information in order to take steps to protect themselves and their properties. Awareness of the hazard is not enough; people need to be told what they can do about the hazard. Thus, projects should include information on safety,health and property protection measures. Research has shown that a properly run local information program is more effective than national advertising or publicity campaigns. Therefore, outreach projects should be locally designed and tailored to meet local conditions. Community newsletters/direct mailings: The most effective types of outreach projects are mailed or distributed to everyone in the community. In the case of floods,they can be sent only to floodplain property owners. News media: Local newspapers can be strong allies in efforts to inform the public. Local radio stations and cable TV channels can also help. These media offer interview formats and cable TV may be willing to broadcast videos on the hazards. ��::3sS The two previous activities tell people that they are exposed to a hazard. The next step is to provide information to those who want to know more. The community library and local websites are obvious places for residents to seek information on hazards,hazard protection, and protecting natural resources. Books and pamphlets on hazard mitigation can be given to libraries, and many of these can be obtained for free from state and federal agencies. Libraries also have their own public information campaigns with displays, lectures and other projects,which can augment the activities of the local government. Today, websites are commonly used as research tools. They provide fast access to a wealth of public and private sites for information. Through links to other websites,there is almost no limit to the amount of up to date information that can be accessed on the Internet. In addition to online floodplain maps,websites can link to information for homeowners on how to retrofit for floods or a website about floods for children.

HAZARD FC) Residents and business owners that are aware of the potential hazards can take steps to avoid problems or reduce their exposure to flooding. Communities can easily provide map information from FEMA's FIRMs and Flood Insurance Studies. They may also assist residents in submitting requests for map amendments and revisions when they are needed to show that a building is located outside the mapped floodplain. Some communities supplement what is shown on the FIRM with information on additional hazards, flooding outside mapped areas and zoning. When the map information is provided, community staff can explain insurance,property protection measures and mitigation options that are available to property owners. They should also remind inquirers that being outside the mapped floodplain is no guarantee that a property will never flood. ....................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................... PROPERTY T 0 While general information provided by outreach projects or the library is beneficial,most property owners do not feel ready to retrofit their buildings without more specific guidance. Local building department staffs are experts in construction. They can provide free advice,not necessarily to design a protection measure,but to steer the owner onto the right track. Building or public works department staffs can provide the following types of assistance: — Visit properties and offer protection suggestions — Recommend or identify qualified or licensed contractors — Inspect homes for anchoring of roofing and the home to the foundation — Explain when building permits are needed for home improvements. A Program for Public Information(PPI) is a document that receives CRS credit. It is a review of local conditions, local public information needs, and a recommended plan of activities. A PPI consists of the following parts,which are incorporated into this plan: The local flood hazard — The property protection measures appropriate for the flood hazard — Flood safety measures appropriate for the local situation — The public information activities currently being implemented within the community,including those being carried out by non-government agencies — Goals for the community's public information program — The outreach projects that will be done each year to reach the goals — The process that will be followed to monitor and evaluate the projects ...............OC4��............... �M ��q 0��S�J /C S C Communities in Monroe County could receive credit under Activity 330—Outreach Projects as well as Activity 350—Flood Protection Information. Credit is available for targeted and general outreach projects.

FDEM encourages the LMS to pre-identify(and"bank")projects and gather initial data to facilitate the priority setting process and aid in more rapid consideration in the post-disaster period. The LMS allows submissions from jurisdictions,utility agencies, and non-profit organizations, among others. It is expected that initiatives "banked"into the Mitigation Strategy(found in Section 7) are identified based on information and data contained within this plan and other relevant resources. Initiatives are expected to be consistent with current policies and regulations,technically feasible, likely to have high political and social acceptance, and be achievable using existing authorities and staff. These details are identified in the preliminary enhanced STAPLEE prioritization introduced in Section 6. This appendix further details the County's prioritization process for the projects prioritized for HMA grant consideration. .......................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................

Initiatives may be placed on the Mitigation Action Plan list by any eligible entity that provides minimum information. New additions to the Mitigation Action Plan during this cycle are considered part of the "bank"moving forward. The Working Group allows submissions on a quarterly basis, so that eligible entities are not constrained by an annual opportunity to identify and pursue projects and funding. When an initiative submits a new project outside of the 5 year LMS update cycle, they are to do so by submitting a Notice of Intent(NOI) form,which may be obtained from the LMS Coordinator through the IIIAarvroe Courity,III:III III I III IIL...ou III III iii t iii atiii air.m Strategy 3 a iir.m u a iii. 2.

Submission of NOIs require the following minimum information: — Name of owner/entity; — Name and brief description of initiative/project; — "Best estimate"of project costs; and — Identification of mitigation category,mitigation goal(s), and hazards addressed. ....................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................... TEP D.7.2 w TWO: PRIORI .................u�ED MITIGATION INITIATIVES' Implementation of the identified mitigation actions from Step One, especially site-specific initiatives, is usually dependent upon the availability of funding. A project that is on the Step One(Mitigation Action Plan)list is moved to the Step Two (Prioritized) list when the owner/entity anticipates developing and submitting the formal application to FDEM and FEMA; at this point,the LMSWG is charged with prioritizing projects for available funding.Notices of Funding Availability(NOFA)may be issued annually(i.e. for FEMA's FMA and BRIC programs)or after disasters that yield HMGP funds, in which case NOFAs are usually issued within 90 days. Whether on an annual basis or post-disaster,the LMSWG members would be notified and eligible entities would then decide whether they are prepared to submit the applicable information to formalize initiatives from Step One. The LMS working group is charged with developing a prioritized list of initiatives pursuant to State requirements (Chapter 27P-22.006); at any given time,priorities may change due to various factors such as recent damage, availability of non-federal cost share, or changes in priorities of the funding agency. When a NOFA is anticipated or received,the LMS Coordinator will notify entities that have initiatives in the Mitigation Action Plan. In order to have an initiative forwarded to the funding agency, detailed data specified in the Characterization Form,which can be obtained from the LMS Coordinator and will be sent out with the announcement of a NOFA, are required so that the LMSWG's Ranking Subcommittee can process and determine priorities—thus creating a Prioritized Initiative (Step Two)list. The most up to date Prioritized List can be found on the following page. The following minimum information will be required: — Name of owner/entity and the point of contact responsible for providing the detailed information; — Initiative/project title, description of the project, whether it benefits a critical facility, and whether the applicant has the legal authority to undertake the project; — Estimate of how quickly the project could be started and how long it would take to complete; — The LMS goals/objectives addressed, a scope of work and need, and the hazard(s) and problem(s) it would address; — Description of the general benefits, including number of people impacted, economic benefits, social benefits, environmental benefits, and whether historic resources are affected; — Estimated total project costs and whether a formal Benefit-Cost Analysis has been prepared or if the estimated benefits are based on the worksheet to approximate a Benefit-to-Cost Ratio; — Statements regarding feasibility; consistency with other plans,policies, codes and ordinances;permits and approvals necessary; level of effort to implement; and likely reception by the public; and — An attachment to approximate benefits and costs.

In order to maintain records that demonstrate progress toward the mitigation goals, such as the details found in Section 2.9,the LMSWG recognizes that is important to track completed initiatives as well as initiatives that are deleted from the list, including those for which sufficient information was not provided to retain on one of the other lists. At least once a year, entities that have initiatives on either list (regardless of source of funding)will report whether these initiatives have been completed, deleted, or are carried forward—subsequently remaining on the appropriate list. At any time, entities may request that an initiative be deleted. The LMS Coordinator will maintain a list of such action.
