ITEM BACKGROUND: In order for the County to meet Community Rating System (CRS) Class 4 criteria, the Land Development Code needs to be amended to eliminate the ability for a manufactured/mobile home to be placed at an elevation below base flood elevation (BFE) within the Urban Residential Mobile Home —Limited District (URM-L). The County currently allows mobile homes to be rebuilt on 36' piers, instead of being built to minimum flood elevation standards of other structures. The proposed change would result in the same level of flood protection (elevation requirements) for all homes (manufactured or non -manufactured) within the County. Currently, the Monroe County Floodplain regulations allow for the substantial improvement and replacement of manufactured/mobile homes in URM-L zoned manufactured/mobile home parks to be placed at 36 inches above grade, if the unit meets the criteria of Section 1224(b)(4), regardless of flood risk, including FEMA Special Flood Hazard Areas (SFHA) flood zones or BFE, unless the manufactured/mobile homes are substantially damaged by flooding. Sec. 1224(b)(4) Manufactured homes. a. Effective June], 1977, no manufactured home not already in place shall be placed within areas of special flood hazard except in an existing manufactured home park or subdivision, as hereafter defined. In the event that the Federal Emergency Management Agency eliminates the existing manufactured home park or subdivision requirement of 44 CFR 60.3(c)(12), then no manufactured home may be placed below the base flood elevation. b. A manufactured home that is to be placed on a qualified lot rnaY be placed at an elevation below base flood elevation provided that: 1. The lot which the manufactured home is to be placed is located in an existing manufactured home park or subdivision and is contiguous to and surrounded by manufactured homes not at base flood elevation. 2. The manufactured homes that are placed or substantially improved (for other than substantial damage due to a flood) on sites in existing manufactured home parks or subdivisions in flood hazard areas shad be elevated so that the mangfactur°ed home chassis is .Qipported lay' r°einf6r�ced pier°s or gather° foundation elements that are no Tess than 36 inches in height ahwly thegrade at the site. A lower foundation system could be used if the top of the finished floor of the manufactured home or the bottom of the beam (for V zones) would be at or above the base flood elevation using such foundation. 3. All other foundations requiring elevation of the structure in order to meet the floodplain standards must comply with Section 122-3(c), the provisions of subsection (b)(5) of this section or chapter 18 of the Florida Building Code whichever is applicable. On January 21, 2020, the County was informed to qualify for a CRS Class 4 rating, the County must meet a set point criteria in the CRS program and meet certain prerequisite standards, including an effective regulatooy program to prevent a recurrence of flooding. Communication with ISO Program Coordination/CRS Specialists included that a modification to current floodplain regulation provisions for elevating manufactured/mobile homes is necessary to meet the class 4 prerequisite. Allowing mobile homes to build back on 36' piers, below the minimum flood elevation does not meet the Class 4 prerequisites. Note, ISO/CRS Specialists are responsible for reviewing community requests for Community Rating System classification and verifying implementation of activities credited by the CRS prior to FEMA granting the CRS class. Excerpt from the CRS Coordinator's Manual: 211.c. Class 4 Prerequisites A Class 4 or better community must demonstrate that it has programs that minimize flood losses, minimize increases in future flooding, protect natural floodplain functions. and protect people from the dangers of flooding. Even though it pray, leave enough points. a community that cleared most of the buildings from its floodplain with disaster assistance funds after a flood cannot be a Class 4 or getter if it does not have an effective regulatory pr.ogr.anr to prevent a recurrence of the problem.. The community must demonstrate that it has taken appropriate steps to eliminate or minimize future flood losses. To do this. a Class 4 or better community must receive credit for the following CRS activities. (a) Activity 430 (Higher Regulatory Standards) —Tire community must show that it enforces higher regulatory standards to manage new development in the floodplain. (i) The community must adopt and enforce at least a 1-foot freeboard requirement (including equipment or mechanical items) for all buildings constructed, substantially improved and/or reconstructed due to substantial damage. and buildings allowed to be floodproofed, throughout its SFH: . except those areas that receive t3SP credit under Activity 420 (Open Space Preservation). In unnumbered A. AOand V Zones. the community must first determine a base flood elevation consistent with the techniques credited under Activity 410 (Flood Hazard Mapping). If the provision with the elevation exception was removed from the Land Development Code, the County may qualify for a Community Rating System (CRS) Class 4 rating. This would increase premium discounts for structures in the unincorporated SFHA from 25% to 30%, which would equate to a savings of approximately $6,376,373 per year, from the current discount of approximately $5,317,202. History of CRS Participation and Discount Based on this information, staff is evaluating Land Development Code revisions as follows. The proposed text changes are shown with additions underlined and deletions are sue. Sec. 1224... Standards for Issuance of Building Permits in Areas of Special Flood Hazard. (a) Generaliv. No building permit for proposed construction or development activity within an area of special flood hazard shall be granted, by the Building Official or the floodplain administrator, unless the proposed new construction is in compliance with the standards set forth in this chapter. In all areas of special flood hazard, the following standards apply: (b) Additional standards. In all areas of special flood hazard where base flood elevation data has been provided the following provisions are required: (4) Manqfactured homes. a.

All of these manufactured/mobile homes (100%) are within the SFHA flood zone (see attachment maps). Staff has reviewed the eight URM-L designated manufactured/ mobile home parks and provided the following summary based on an analysis of best available data: Manufactured/ mobile # of MHs # of home (NM) count* # # that must additional URM-L existing Property based on June field currently currently elevate to affected MHs manufactured/ address visits, aerial imagery SFHA elevated elevated at BFE +lft with proposed mobile home parks & department data below or above under policy change (does not include BFE BFE current to remove 36" other structure types) code** exception* Stock Island I 5031 5th Ave 77*** AE 8 2 75 2 0 00126550-000000 2 Stock Island 6500 93 * * * AE 9 93 0 45 48 00126090-000000 Maloney Ave 3 Stock Island 6531 12*** AE 9 9 3 4 5 00125740-000000 Maloney Ave AE 10 4 Stock Island 6529 4 AE 9 3 1 3 0 00125750-000000 Maloney Ave AE 10 5 Stock Island 6511 10*** AE 9 10 0 0 10 00132350-000000 Maloney Ave AE 10 6 Stock Island 6621 24* * * AE 9 24 0 14 10 00125770-000000 Maloney Ave AE 10 Big Coppitt 00121761- 55 ca AE 10 7 000000-F 131*** 126 5 88 38 ChiccaoRd VE 10 00121762- 000100+ AE 9 Cudjoe AE 11 8 00188681- 701 Spanish 424*** VE 12 289 135 248 41 Main Dr 000000+ VE13 VE 15 Total 775 556 219 404 152 *1 his does not include vacant spaces/parcels. "This estimate could increase, if during permitting a property is determined to have been substantially damage by flood. * * * This analysis is not intended for the recognition of development rights or to identi_ fy permitted or unpermitted work, and should not be used nor relied upon for these items. There are approximately 20,200 total structures in the SFHA flood zone. Of these structures, there are approximately 775 manufactured/mobile homes in these eight (8) existing manufactured/mobile home parks within the URM-L designation in the unincorporated County. Staff estimates of the 775 manufactured/mobile homes, that approximately 219 (28%) are currently elevated at or above BFE and 556 (72%) are currently elevated below BFE. Some of the 775 manufactured/mobile homes would already be required to elevate based on the current adopted regulations because the home is not contiguous to and surrounded by manufactured homes not at base flood elevation (BFE). Staff estimates this would be approximately 404 (52%) the 775 manufactured/mobile homes. It is important to note that as these manufactured/mobile homes are replaced and elevated to BFE under the current provisions of the Floodplain Regulations, the manufactured/mobile homes units contiguous to these replaced units will then be subject to elevating to BFE (i.e. a continual domino effect). If the provisions with the elevation exception were removed from the Land Development Code, then the manufactured/ mobile homes within the eight (8) existing URM-L designated manufactured/ mobile home parks would be required to elevate above current requirements upon replacement. This would be a gradual process, as the units would not need to be elevated until they are replaced or substantially damaged or substantially improved (the proposed change would apply at the time of replacement). Staff estimates of the 775 manufactured/mobile homes, that approximately 152 (20%) would be the number of additionally affected manufactured/mobile homes [i.e. if elevation exception was removed, these units would be required to elevate above the currently required 36 inches, even if the units were contiguous to and surrounded by manufactured homes also not at base flood elevation (BFE)]. Overall, the rate of replacement in these URM-L parks is slow, so it would take multiple years before all the manufactured/mobile homes would be elevated. Staff would also suggest an amendment to allow detached dwellings within the URM-L district which will provide property owners with another housing option with greater resilience and wind - load provisions. Note, as proposed a detached dwelling would be permitted as of right through the approval of a building permit. While approved via a building permit, the request for a detached dwelling would be subject to the requirements of the comprehensive plan and the other provisions of the land development code, such as development standards, bulk regulations, rate of growth ordinances, etc. As a whole, the proposed elevation change will result in the same level of flood protection and resiliency as other homes (i.e. non -manufactured) within the County. While it is recognized that there are financial impacts in elevating manufactured/mobile homes higher than what is currently required, the benefits (not being damaged by flooding) of elevating to the BFE + lft when the home is replaced generally outweighs the elevation costs in the long term. Since the impacts of Hurricane Irma, the County has been working on numerous recovery, post disaster and resiliency proposals/programs and there are several potential funding opportunities for the owners of these manufactured/mobile homes to participate in rebuilding and elevating their homes. Note, if owners of these manufactured/mobile homes participate in rebuilding and elevating their homes with federal funds, the manufactured/mobile homes would need to be elevated at least 2 feet above BFE due to requirements within the Code of Federal Regulations. There following programs are potentially available to replace, elevate and reduce the risk of flooding: • FEMA Hazard Mitigation Grant Program (HMGP) for mitigation measures • Flood Mitigation Assistance (FMA) Grant Program to reduce or eliminate the long-term risk of flood damage to buildings, manufactured homes and other structures insured under the NFIP Pre -Disaster Mitigation (PDM) funds for hazard mitigation planning and implementation of mitigation projects Rebuild Florida Program to demo, repair, reconstruct and elevate primary homes Voluntary Home Buyout Program utilizing Community Development Block Grant -Disaster Recovery funding Research conducted by the Florida Floodplain Managers Association (FFMA) in 2019, determined the following Florida communities do not allow the 36-inch elevation option: 1.

Morehead City, NC County, A local example with higher regulatory standards is the City of Key West which has adopted the following requirements for manufactured/mobile homes: Sec. 122-1276. - Standards. Manufactured housing may be permitted in the city if the units comply with the following standards: (1), The city's adopted building codes-, (2) The state building standards of F.S. chs., 320 and 553-, ,(3), U.S. Department of Housing and Urban, Development Manufactured Home Construction and Safety Standard's of 1974,(i.,e-: F.S. § 320.823):-, ,(4), All applicable provisions of the comprehensive plan, and land development regulations; ,(5)). Adopted city fire codes; and ,(6), All manufactured housing shall be designed in a manner compatible with conventional housing including rooffine, fenestration, foundation and similar features, impacting compatibility.The finished floor elevation for manufactured housing shall be designed with site improvements necessary to preserve compatibility with surrounding structures. Sec. 34-1345. - Manufactured homes. (1) Generaf. All manufactured homes instailled in flood hazard areas shall be installed by an installer that is licensed pursuant to F.S. § 320-8249, and shall comply with the requirements of Chapter 15C.- 1, F.A.C. and the requirements of this ordinance. If located seaward of the coastal construction control line, all manufactured homes shall comply with the more restrictive of the applicable requirements. (2) Foundations. All new manufactured homes and replacement manufactured homes installed in flood hazard areas shall be installed on permanent: reinforced foundations, that: (a), In flood hazard areas (Zone A) other than coastal high hazard areas, are designed in accordance with the foundation requirements of the Florida Building Code, Residential Section R322.2 and this ordinance- (b), In coastal high hazard areas (Zone V), are designed in accordance with the foundation requirements of the Florida Building Code, Residential Section R322.3 and this, ordinance. (3) Anchoring. All new manufactured homes and replacement manufactured homes shall be installed ,using methods, and practices which, minimize flood damage and shall be securely anchored to an adequately anchored foundation system to resist flotation,, collapse or lateral movement. Methods of anchoring include, but are not limited to, use of over-thie-top or frame ties to ground anchors. This anchoring requiirement is in, addition to applicable state and local anchoring requirements, for wind resistance. (4) Elevation. Manufactured homes that are placed, replaced, or substantially improved sha.11 comply with, section 34-136(4)(a) or (b) of this ordinance, as applicable. (a), General efevation requirement. Unless subject to the requirements of section 34-136( ' 4)(b) of this, ordinance,, all manufactured homes that are placed, replaced, or substantially improved on sites located: 1. Outside of a manufactured home park or subdiviston-, 2. In a new manufactured home park or subdivislon;; 3. In an expansion to an existing manufactured home park or subdivision; or 4.

While Monroe County's approach would eventually get most mobile homes elevated to where they should, be the regulation leaves a portion of the most vulnerable current population and building inventory at risk. Some mobile homes may never be required to elevate since no one is adjacent to them. This would be the same as only requiring elevation of a SI/SD structure when the adjacent structure has been elevated which we would never accept. As a group it was decided Monroe County's current regulations do not meet the Coordinator Manual's intent, which is to get everyone elevated as soon as possible. A modification for a class 4 could be considered only after the regulation is amended to meet the class 4 prerequisite Best regards, Sherry Sherry Harper Director, Natural Hazards Phone: +1.850.682.1998 1 Mobile: +1.850.902.5075 1 Fax: +1.201.748.1869 verisk.com I vCard I Map I Email lrl County�� Mope ; c'�' )' �� r� "16- 4 BOARD OF COUNTY COMMISSIONERS ,- � + Mayor Heather Carruthers, District 3 Mayor Pro Tem Michelle Coldiron, District 2 IleOI1da Keys Craig Cates, District 1 J ��1 David Rice, District 4 Sylvia J.

AGENDA ITEM WORDING: Presentation of draft unincorporated Monroe County Repetitive Loss Area Analysis (RLAA), which is a required element for the County to achieve Class 4 in the Community Rating Sytem (CRS) which would give a 30% discount (estimated annual savings of $6.3 million or average annual policy holder discount of $464) to all National Flood Insurance Program policy holders, instead of a 25% discount (estimated annual savings of $5.1 million or average annual policy holder discount of $350), which Monroe County currently has (CRS rating — Class 5). ITEM BACKGROUND: Participants in the National Flood Insurance Program (NFIP) are able to enter the Community Rating System (CRS) if they are considered in "good standing". Monroe County was not in good standing for decades. After 6 community assistance visits and over 300 audit findings, the County successfully received a letter of good standing and was eligible to enter the CRS program. Over the past several years the County achieved a 25% discount by becoming a class 5 in the CRS program. Class 5 last year saved policy holders $5.1 Million dollars. Each year, a similar amount is saved by this ranking. Prior to Hurricane Irma the County entered into a contract with Lori Lehr, CFM, consultant to work toward a Class 4, which would save approximately $6.4 Million annually. See table below. The County must score over 3000 points to enter a class 4 Ptremiurn Reduction CRS Class Credit Points In SFHA Outside SFHA 1 4,500+ 45% 10% 2 4,000-4,499 40% 10% 3 3, 500-3, 999 3 5 % 10% 4 3,000-3,499 30% 10% 5 2,500-2,999 25% 10% 6 2,000-2,499 20% 10% 7 1,500-1,999 15 % 5 8 1,000-1,499 10% 5 9 500-999 5 % 5 10 0-499 0 % 0 Further, the County must also complete certain threshold items including: • Sea Level Rise projections impact on drainage infrastructure (already completed and approved by the Board). • Drainage Maintenance Plan (completed) • Repetitive Flood Loss Area Analysis (RLAA) — item being presented on 1/22/20.

One measure of the intensity and impact of these floods is flood insurance claims. Between 1978 and 2017, there were 11,205 flood insurance claims paid in unincorporated Monroe County. Of those, 10,896 (97%) were from the six major storms discussed in Chapter 2. The average claim payments for the last two, Wilma and Irma, were over $30,000 and $35,000, respectively. Many properties in the County have been subject to repetitive floods. Nationally, the cost of paying repetitive insurance claims have made them a priority for the National Flood Insurance Program. Under FEMA's definition of a repetitive loss property, only a little more than 1% of the County's flood insurance polices account for 19% of the claim payments since 1978. Repetitive flooding is therefore a major concern in Monroe County. Analysis Instead of focusing on just the officially designated repetitive loss properties that have flooded two times or more in the past, this analysis looks at repetitive loss areas. An "area" has the repetitive loss properties designated by FEMA and other nearby properties that are exposed to the same flood risk (often called "repetitive loss properties in waiting"). Monroe County has 60 repetitive loss areas which have from one to 699 properties with a total of 9,546 properties. Appendix A has maps and summary data on the 60 repetitive loss areas in unincorporated Monroe County. The data come from on a windshield survey, claims data, and County Appraiser files. The exact location of the 4FEMA-designated repetitive loss properties cannot be identified because of the Privacy Act. For this analysis, there is no differentiation between FEMA repetitive loss, single loss, insured but no claim payments, and uninsured properties. All properties exposed to the repetitive flood hazard deserve attention. Table below is a summary of the areas. Area RL, __. Loss Sintilarh +_w Total : ! ! \ \ m !» 490 , ! _ !> r, z ! : a s , !

Chapter 3 discusses alternative mitg§oprojects maddress these impacts. They are organized under two approaches: Flood control projects Nonstructural projects Sec structures Acquisition Seawalls Elevation • Beach and dune nourishment Mitigation reconstruction • Drainage improvements Barriers • Dry floodproofing • Wet floodproofing Different projects do better in different situations, so Chapter 4 identifies ways to determine the best approaches to mitigate the impacts of repetitive flooding. Chapter 5 concludes with recommendations for the County and for repetitively flooded property owners. County actions focus on protecting critical facilities and roads and helping property owners with information, technical assistance, and funding. Recommended property owner actions include learning about nonstructural measures that they can implement and sources of financial assistance and maintaining flood insurance coverage.

(a) The Act provides that flood insurance shall not be sold or renewed under the program within a community, unless the community has adopted adequate flood plain management regulations consistent with Federal criteria. Responsibility for establishing such criteria is delegated to the Federal Insurance Administrator. (b) This subpart sets forth the criteria developed in accordance with the Act by which the Federal Insurance Administrator will determine the adequacy of a community's flood plain management regulations. These regulations must be legally -enforceable, applied uniformly throughout the community to all privately and publicly owned land within flood -prone, mudslide (i.e., mudflow) or flood -related erosion areas, and the community must provide that the regulations take precedence over any less restrictive conflicting local laws, ordinances or codes. Except as otherwise provided in § 60.6, the adequacy of such regulations shall be determined on the basis of the standards set forth in § 60.3 for flood -prone areas, § 60.4 for mudslide areas and § 60.5 for flood -related erosion areas. (c) Nothing in this subpart shall be construed as modifying or replacing the general requirement that all eligible communities must take into account flood, mudslide (i.e., mudflow) and flood -related erosion hazards, to the extent that they are known, in all official actions relating to land management and use. (d) The criteria set forth in this subpart are minimum standards for the adoption of flood plain management regulations by flood -prone, mudslide (i.e., mudflow)-prone and flood -related erosion -prone communities. Any community may exceed the minimum criteria under this part by adopting more comprehensive flood plain management regulations utilizing the standards such as contained in subpart C of this part. In some instances, community officials may have access to information or knowledge of conditions that require, particularly for human safety, higher standards than the minimum criteria set forth in subpart A of this part. Therefore, any flood plain management regulations adopted by a State or a community which are more restrictive than the criteria set forth in this part are encouraged and shall take precedence.

(a) A flood -prone community applying for flood insurance eligibility shall meet the standards of § 60.3(a) in order to become eligible if a FHBM has not been issued for the community at the time of application. Thereafter, the community will be given a period of six months from the date the Federal Insurance Administrator provides the data set forth in § 60.3 (b), (c), (d), (e) or (f), in which to meet the requirements of the applicable paragraph. If a community has received a FHBM, but has not yet applied for Program eligibility, the community shall apply for eligibility directly under the standards set forth in § 60.3(b). Thereafter, the community will be given a period of six months from the date the Federal Insurance Administrator provides the data set forth in § 60.3 (c), (d), (e) or (f) in which to meet the requirements of the applicable paragraph. (b) A mudslide (i.e., mudflow)-prone community applying for flood insurance eligibility shall meet the standards of § 60.4(a) to become eligible. Thereafter, the community will be given a period of six months from the date the mudslide (i.e., mudflow) areas having special mudslide hazards are delineated in which to meet the requirements of § 60.4(b). (c) A flood -related erosion -prone community applying for flood insurance eligibility shall meet the standards of § 60.5(a) to become eligible. Thereafter, the community will be given a period of six months from the date the flood - related erosion areas having special erosion hazards are delineated in which to meet the requirements of § 60.5(b). (d) Communities identified in part 65 of this subchapter as containing more than one type of hazard (e.g., any combination of special flood, mudslide (i.e., mudflow), and flood -related erosion hazard areas) shall adopt flood plain management regulations for each type of hazard consistent with the requirements of § § 60.3, 60.4 and 60.5. (e) Local flood plain management regulations may be submitted to the State Coordinating Agency designated pursuant to § 60.25 for its advice and concurrence. The submission to the State shall clearly describe proposed enforcement procedures. (f) The community official responsible for submitting annual or biennial reports to the Federal Insurance Administrator pursuant to § 59.22(b)(2) of this subchapter shall also submit copies of each annual or biennial report to any State Coordinating Agency. (g) A community shall assure that its comprehensive plan is consistent with the flood plain management objectives of this part. (h) The community shall adopt and enforce flood plain management regulations based on data provided by the Federal Insurance Administrator. Without prior approval of the Federal Insurance Administrator, the community shall not adopt and enforce flood plain management regulations based upon modified data reflecting natural or man-made physical changes. 1.10e Attachment B - Manufactured home/mobile home analysis [41 FR 46975, Oct. 26, 1976.

The Federal Insurance Administrator will provide the data upon which flood plain management regulations shall be based. If the Federal Insurance Administrator has not provided sufficient data to furnish a basis for these regulations in a particular community, the community shall obtain, review and reasonably utilize data available from other Federal, State or other sources pending receipt of data from the Federal Insurance Administrator. However, when special flood hazard area designations and water surface elevations have been furnished by the Federal Insurance Administrator, they shall apply. The symbols defining such special flood hazard designations are set forth in § 64.3 of this subchapter. In all cases the minimum requirements governing the adequacy of the flood plain management regulations for flood -prone areas adopted by a particular community depend on the amount of technical data formally provided to the community by the Federal Insurance Administrator. Minimum standards for communities are as follows: (a) When the Federal Insurance Administrator has not defined the special flood hazard areas within a community, has not provided water surface elevation data, and has not provided sufficient data to identify the floodway or coastal high hazard area, but the community has indicated the presence of such hazards by submitting an application to participate in the Program, the community shall: (1) Require permits for all proposed construction or other development in the community, including the placement of manufactured homes, so that it may determine whether such construction or other development is proposed within flood -prone areas; (2) Review proposed development to assure that all necessary permits have been received from those governmental agencies from which approval is required by Federal or State law, including section 404 of the Federal Water Pollution Control Act Amendments of 1972, 33 U.S.C. 1334; (3) Review all permit applications to determine whether proposed building sites will be reasonably safe from flooding. If a proposed building site is in a flood -prone area, all new construction and substantial improvements shall (i) be designed (or modified) and adequately anchored to prevent flotation, collapse, or lateral movement of the structure resulting from hydrodynamic and hydrostatic loads, including the effects of buoyancy, (ii) be constructed with materials resistant to flood damage, (iii) be constructed by methods and practices that minimize flood damages, and (iv) be constructed with electrical, heating, ventilation, plumbing, and air conditioning equipment and other service facilities that are designed and/or located so as to prevent water from entering or accumulating within the components during conditions of flooding. (4) Review subdivision proposals and other proposed new development, including manufactured home parks or subdivisions, to determine whether such proposals will be reasonably safe from flooding. If a subdivision proposal or other proposed new development is in a flood -prone area, any such proposals shall be reviewed to assure that (i) all such proposals are consistent with the need to minimize flood damage within the flood -prone area, (ii) all public utilities and facilities, such as sewer, gas, electrical, and water systems are located and constructed to minimize or eliminate flood damage, and (iii) adequate drainage is provided to reduce exposure to flood hazards; (5) Require within flood -prone areas new and replacement water supply systems to be designed to minimize or eliminate infiltration of flood waters into the systems; and (6) Require within flood -prone areas (i) new and replacement sanitary sewage systems to be designed to minimize or eliminate infiltration of flood waters into the systems and discharges from the systems into flood waters and (ii) onsite waste disposal systems to be located to avoid impairment to them or contamination from them during flooding. (b) When the Federal Insurance Administrator has designated areas of special flood hazards (A zones) by the publication of a community's FHBM or FIRM, but has neither produced water surface elevation data nor identified a floodway or coastal high hazard area, the community shall: (1) Require permits for all proposed construction and other developments including the placement of manufactured homes, within Zone A on the community's FHBM or FIRM; (2) Require the application of the standards in paragraphs (a) (2), (3), (4), (5) and (6) of this section to development within Zone A on the community's FHBM or FIRM; (3) Require that all new subdivision proposals and other proposed developments (including proposals for manufactured home parks and subdivisions) greater than 50 lots or 5 acres, whichever is the lesser, include within such proposals base flood elevation data; (4) Obtain, review and reasonably utilize any base flood elevation and floodway data available from a Federal, State, or other source, including data developed pursuant to paragraph (b)(3) of this section, as criteria for requiring that new construction, substantial improvements, or other development in Zone A on the community's FHBM or FIRM meet the standards in paragraphs (c)(2), (c)(3), (c)(5), (c)(6), (c)(12), (c)(14), (d)(2) and (d)(3) of this section; (5) Where base flood elevation data are utilized, within Zone A on the community's FHBM or FIRM: 1.10e Attachment B - Manufactured home/mobile home analysis (i) Obtain the elevation (in relation to mean sea level) of the lowest floor (including basement) of all new and substantially improved structures, and (ii) Obtain, if the structure has been floodproofed in accordance with paragraph (c)(3)(ii) of this section, the elevation (in relation to mean sea level) to which the structure was floodproofed, and (iii) Maintain a record of all such information with the official designated by the community under § 59.22 (a)(9)(iii); (6) Notify, in riverine situations, adjacent communities and the State Coordinating Office prior to any alteration or relocation of a watercourse, and submit copies of such notifications to the Federal Insurance Administrator; (7) Assure that the flood carrying capacity within the altered or relocated portion of any watercourse is maintained; (8) Require that all manufactured homes to be placed within Zone A on a community's FHBM or FIRM shall be installed using methods and practices which minimize flood damage. For the purposes of this requirement, manufactured homes must be elevated and anchored to resist flotation, collapse, or lateral movement.
