AGENDA ITEM WORDING: SUSTAINABILITY: Discussion and direction on work performed under Amendment No. 9 for design of a roadway paving project for Stillwright Point, under the contract with HDR, Inc. for the Roads Vulnerability Analysis and Capital Plan for County-maintained roads, to provide updated modeling information and guidance on permissible raising of roadway elevation without affecting the existing (Pre) hydraulic parameters. TIME APPROXIMATE It:00 A.M. ITEM BACKGROUND: This item is to provide a presentation, followed by discussion and direction from the Board of County Commissioners, on the professional services provided by HDR Engineering, Inc. (HDR) for the Monroe County (County) Roadway Vulnerability Analysis and Capital project for design of a roadway paving project for the Stillwright Point Community. Updated modeling information will be presented to provide guidance on permissible raising of roadway elevation without affecting the existing (Pre) hydraulic parameters. Items to be discussed include: • Amount of paving (road raising) that can be accomplished through a General Stormwater permit from SFWMD. • Updated cost estimates for repaving only and repaving/removal and replacement of road base. o Explanation of the additional challenges and cost incurring for the road base replacement. o Pros/Cons of base replacement • Design and Construction Schedule of work for both options • Flowage Easements and Hydraulic Modeling At the December 13, 2023 commission workshop held to discuss options for road adaptation projects for Stillwright Point, the commission directed staff to move forward with design of a potential roadway paving project for Stillwright Point. The amendment was approved at the January 31, 2024 BOCC meeting and included the design of a roadway paving project with an option for construction for a new roadway base. The estimate for a paving project without a new road base was $2,587,062. 3441 The estimate for a paving project with a Base Reconstruction Alternative was $4,407,703. Estimates will be updated during the presentation.

A paving.only road maintenance project is likelya'renewal'of capital acilities. Policyrequires consideration of sea level rise,but does not require designing to that standard. lfthe paving-only maintenance proect is pursued,recommendation is to cle7ri policvso that the decision not to consider sea-levelrise is notl inconsistent with the intent to considerit.Policycan also be clarified to state that maintenance-onlypr6ects do nothave to consider sea level rise. Policy 1502.1.5: By 2025, Monroe County shall initiate an inventory of existing and IIII� planned infrastructure up to the 2045 horizon, based upon the vulnerability mapping, updated elevation data, the Countywide Roads and Stormwater Vulnerability Assessment, the Watershed Management Plan,the GreenKeys Plan and other appropriate vulnerability information for capacity to accommodate projected sea-level rise over the life expectancy of that infrastructure.Monroe County shall identify the infrastructure within those areas, its useful life and any retrofits or capital projects necessary to address the impacts of sea level rise. • These strategies may include defense, accommodation, or and relocation projects, or not building planned infrastructure in vulnerable locations,to address the impacts of sea level rise. Monroe County will consider developing design criteria, in conjunction with a broader asset management planning process. Ord. No. 013-2022 , § 2(Exh. 1), 8-17-2022). Analysis: Its likely that the choice to NOT elevate the road to address sea level rise or providestormwater management is contemplated by this policybecauseit would be a decision to NOT build infrastructure(elevate roads)in a vulnerable location. No recommendation for chance Pay 1502.1.6: Monroe County shall utilize a planning,design and permitting standard for IIII� infrastructure and public facilities that includes a sea level rise(SLR)assumption of 10"-17"by 2040,based on a year 2000 baseline,as developed bythe Southeast Regional Climate Compact (2019 update).Adaptation and resiliency planning strategy development shall also considerthis sea level rise projection.The County shall continue to review and update sea level rise projections when new and pertinent data is available. (Ord.No.013-2022,§2(Exh.1),8-17-2022) Analysis: This policy does require infrastructure and public facilities projects to account for sea level rise and a paving only road maintenance project may be considered infrastructure and/or a public facility requiring it to meet this design standard, if the having-on r�uject is�ursue�,the recommendation is to modify this Dolicv to recognize that there may be instances where the County decides not to build infrastructure projectsto meet this standard because of the environmental challenges of the location. Pay 1502.1.7: Monroe County shall ensure that new,renovated and replacement public facilities and infrastructure,such as streets and bridges,water and wastewater treatment plants,police stations and fire stations,and any other public facilities that the County has authority over,are designed in a manner which considers the useful life of public facilities and infrastructure.The County shall also considerthe potential impacts from flood risk,climate change,including rising sea levels and shoreline stabilization needs,on its infrastructure and public facilities.(Ord.No. 013-2022, §2(Exh.1),8-17-2022) Analysis: It is likely that a paving-only road maintenance project could be considered renovated` infrastructure. Does this policy prohibit a paving-only road maintenance project?Maybe/maybe not,but if the paving onbL r-o pursued,the recommendation is to modi the oli to recognize thattherp maybe instances where the County decides not to build infrastructure r °ectsto at this standard because of the environmental challenges of the location, 00 a III � �III IIIIIIIIIII�I��i�lilllolll�""' �'�""'`� Illlllllllll�l�i 11p0�' • The intent of the policies is to plan for current and future flooding conditions by designing projects to account for them in their design. • While one policy does contemplate that there may be instances where the IIIIIII� County does not actually design projects this way and may not adapt infrastructure in those locations, the intent of the other policies is to adapt infrastructure for sea level rise. IIIIIIIUu� • If the County does implement a paving-only project, some may oppose that approach (seeking a longer-term fix) and use certain policies to challenge the project as inconsistent with Comp Plan. If the paving-only project is pursued, recommendation is to modify policies to better account for the fact that the County may notada titsinfrastructureto address sea level rise and futureflooding and that projects may end up being •maintenance only'ratherthan adaptation, q III � IIII�III • Flood-related real estate disclosures take 2 forms: 1) General flood risk notification 2) Notificationfor certain properties subject to flood risl<(waterfront/shoreline IIIIIIIU IIIIIIIIII example) IIIIIIIIII • Florida is likely to increase the amount of information required in real estate transactions related to flooding: � w HB 7049,if signed bythe Governor, will require disclosure offiling insurance claims related to flood damage(including tidal flooding and rainfall flooding)and recei t of Federal assistance related to flood damage to the property owner. • Leon County general flood disclosure: It shall be unlawful for a seller or landlord of residential property, with knowledge U that such property has experienced flooding or is otherwise flood prone,to fail to disclose such facts in writing to a prospective buyer or tenant when such flood conditions are not readily observable and are not known to the prospective buyer or tenant • Broward,Delray and others for shorelines/seawalls: • The following disclosure in not less than fourteen-point,capitalized,bold-faced type: THIS REAL ESTATE IS LOCATED INA TIDALLYINFLUENCED AREA.

A designation of areas where elevations are low, right of way is constrained,flooding conditions are occurring now, routinely, and road designs (elevation and drainage) may not be able to meet service expectations. • Why do it? A policy tool to clarify how the County will evaluate projects in those "constrained" areas and manage future obligations and liability. • Where would it apply.
