ITEM BACKGROUND: This agenda item provides a resolution setting an Interim Standard for determining the elevation of future road improvement projects in Monroe County as specified in the Final Report for the Monroe County Pilot Roads Project: The Sands and Twin Lakes Communities and directing initiation of a Countywide Roads Analysis to identify near -term roads subject to risk. The King Tides in 2015 provided a preview of what the County can expect as sea level rise becomes a reality. The impacts exemplify flooding from events but also from more regular tidal intervals that would be expected to be more impactful with higher sea levels. Knowing that the County would be addressing increased flooding from King Tides, storm events and /or general sea level rise countywide, the County decided to move forward with a "Pilot effort" to test methodologies for determining future flood risk scenarios and the policy framework for making these decisions relative to ongoing roadway improvement projects. Two communities were chosen for this study where impacts from the King Tides in 2015 were highest, one in Key Largo and one in Big Pine Key. Specific roadway areas within those communities were further defined as the Shaw, Crane, Adams area in Key Largo area as well as Father Tony Way and the Avenues in Big Pine Key. Pilot Roads Proiect Linkage to GreenKeys Earlier this year, Monroe County accepted the GreenKeys Sustainability Action Plan which had several recommendations related to infrastructure planning in light of future sea level rise projections. The GreenKeys plan showed that approximately 150 miles of County roadways may be exposed to intermittent flooding by 2030. Therefore the recommendations design criteria will need to consider this larger county -wide need to assure that further recommendations for road elevation projects are developed appropriately. Recommendations from the GreenKeys Plan relevant to this Pilot Study include: ■ 1 -19, "Pilot project to conduct Comprehensive Feasibility Study for Enhanced Stormwater and Tidewater Criteria (prioritizing areas) for near -term areas subject to inundation risk, including nuisance flooding (in two locations). ■ 2 -14, "Conduct a countywide roads analysis to identify near -term roads subject to inundation risk, including nuisance flooding. This will include researching where related green infrastructure would be appropriate. Increase the percentage of funding invested in green infrastructure." ■ 2 -36, "Ensure that all new nuisance flooding data informs future road decisions. These data will also need to be considered for future road decisions. This will require coordination with FDOT for impacts to State Roads (U.S. Highway 1). Pilot Roads Report Overview The Final Report for the Pilot Roads project is being presented to the County Commission in three (3) parts. The three parts are: • Part 1 of the Report and BOCC presentation in November 2016 focused on: • Project Background • Assumptions and Methodology • Results of analysis for design alternatives • Cost Comparisons between alternatives • Part 2 of the Report and BOCC presentation in December 2016 focused on: • Brief overview of alternatives and issues presented at November 22 BOCC meeting • Legal background regarding level of service for roads and drainage • Key factors to consider under 4 broad categories • Case studies to address sea level rise in road improvement projects • Developing a uniform countywide policy to address sea level rise in road improvement projects • Part 3A Resolution in January 2017 focuses on acceptance of the Final Report for the Monroe County Pilot Roads Project: The Sands and Twin Lakes Communities including its recommendation related to the two Communities and directs staff to determine final cost estimates for the design and construction of the Recomendations in Section 4.5 of the Final Report and direct staff to move forward with the design phase for the Recommendations. • Part 3B Resolution in January 2017 focuses on setting an Interim Standard for determining the elevation of future road improvement projects in Monroe County as described in the Final Report for the Monroe County Pilot Roads Project: The Sands and Twin Lakes Communities and directs staff to begin moving forward with a Countywide Roads Analysis to identify near -term roads subject to inundation risk, including nuisance flooding. The Resolution recognizes that a Countywide Roads Analysis has been recommended in the GreenKeys Sustainability Action Plan (Recommendation 2 -14) that will help develop an understanding of the economic and policy impacts of adopting an annual flooding return period with a sea level rise assumption for future road improvement projects. The Resolution also recognizes that the Countywide Roads Analysis will take some time to complete, but in the meantime the Interim Standard included in the Recommendations and Appendix 2 Methodology from the Final Report are an appropriate standard for determining the elevation of road improvement projects. It should be noted that the Resolution acknowledges that the Countywide Roads Analysis may result in different standards for determining the elevation of road improvement projects based upon projected levels of sea level rise in the future. The action directed is to 1) Approval of the Interim Standard and 2) move forward with a Countywide Roads Analysis.

WHEREAS, Monroe County roads have been impacted by tidal flooding in 2015 and 2016 from King Tides; and WHEREAS, knowing that Monroe County would be addressing increased flooding from King Tides, storm events and /or sea level rise countywide, the County decided to move forward with a "Pilot Roads Project" to test methods for determining future flood risk scenarios and set a policy framework for making road elevation decisions relative to future road improvement projects; and WHEREAS, the Board of County Commissioners accepted the GreenKeys Sustainability Action Plan in 2016 which included Recommendation 1 -19 for a "Pilot project to conduct a Comprehensive Feasibility Study for Enhanced Stormwater and Tidewater Criteria (prioritizing areas) for near -term areas subject to inundation risk, including nuisance flooding (in two locations)"; and WHEREAS, specific roadway areas were chosen within two communities for the study where impacts from King Tides were the highest including the Twin Lakes Community in Key Largo (Shaw Drive, Crane Street and Adams Drive) and the Sands Community in Big Pine Key (Father Tony Way and the Avenues); and WHEREAS, the Final Report for the Monroe County Pilot Roads Project: The Sands and Twin Lakes Communities, includes a Methodology and Technical Background (Part 1), Recommendations and Legal and Policy Analysis (Part 2), Appendix 1: "Methodology for development of flood level estimates for the two communities" and Appendix 2: Draft Ordinance; and WHEREAS, the methodology for development of flood level estimates for the two communities identifies water elevations that represents values for an allowable annual flooding return period (not to exceed 7 days) and also includes sea level rise projections (IPCC AR5 Median from the Southeast Regional Climate Compact's Unified Sea Level Rise Projection, 2015) in determining desired final roadway elevations for road improvement projects; and WHEREAS, the GreenKeys Sustainability Action Plan also included Recommendation 2 -14 to "Conduct a Countywide Roads Analysis to identify near -term roads subject to inundation risk, including nuisance flooding" and Recommendation 2 -36 to "Ensure that all new nuisance flooding data informs future road decisions. These data will also need to be considered for future road decisions "; and WHEREAS, the Countywide Roads Analysis (Recommendation 2 -14) will help develop an understanding of the economic and policy impacts of adopting an annual allowable flooding return period with a sea level rise assumption for future road improvement projects; and WHEREAS, because the Countywide Roads analysis will take some time to complete, in the interim, the Recommendations and Appendix 1 Methodology from the Final Report for the Monroe County Pilot Roads Project: The Sands and Twin Lakes Communities serves as an appropriate Interim Standard for determining the elevation of road improvement projects; and WHEREAS, the County realizes the Countywide Roads Analysis may result in different future standards for determining the elevation of road improvement projects based upon projected levels of sea level rise in the future and will therefore use the Interim Standard until a Revised Standard is accepted and approved. THEREFORE BE IT RESOLVED by the Board of County Commissioners of Monroe County that: The above recitals are hereby incorporated into this resolution as restated herein constitute the legislative findings and intent of the Board of County Commissioners of Monroe County, Florida. The Recommendations and Appendix I Methodology from the Final Report for the Monroe County Pilot Roads Project: The Sands and Twin Lakes Communities will serve as an appropriate Interim Standard for determining the elevation of road improvement project until a Revised Standard is developed in the future. In order to determine the countywide impacts of establishing a uniform methodology for incorporating sea level rise projections into future road improvement projects, the Board of County Commissioners hereby directs staff to move forward with a Countywide Roads Analysis project to identify near -term roads subject to inundation risk, including nuisance flooding. The Board of County Commissioners hereby directs staff to budget funds in the FY17 /18 budget for the Countywide Roads Analysis project. This resolution shall take effect immediately upon adoption.
