Docusign Envelope ID: AADFOE75-B4D9-497C-9EO1-CC295BDCOA36 May 1, 2025 / Page 3 of 9 11723.11 —Vulnerability Assessment City of Sunny Isles Beach 100 -year return period (1% annual chance) flood event. d. Land use data — sourced from the OF GeoPlan Center future land cover data for the entire state, which is updated annually as more data become available from various municipalities. Florida 2060 and Florida 2070 projects land use scenarios (UF GeoPlan Center, 2022). Local water management districts, counties, and the CITY. The identified critical CITY assets will be assembled in GIS. The GIS metadata should incorporate a layer for each of the four asset types as defined in s. 380.093(2)(a) 1-4, F.S. GIS files and associated metadata must adhere to the Resilient Florida Program's GIS Data Standards, and raw data sources will be defined within the associated metadata. In the process of researching background data, the CONSULTANT will identify data gaps, where missing data or low -quality information may limit the VA's extent or reduce the accuracy of the results. The CONSULTANT will present the CITY with recommendations to address the identified data gaps. The CITY will determine if funding is available and take remedial action to rectify any gaps of necessary data, if applicable. Deliverables: CONSULTANT will provide the following: 1) a technical report to outline the data compiled and findings of the gap analysis; 2) a summary report to include recommendations to address the identified data gaps and actions taken to rectify them, if applicable; and 3) GIS files with appropriate metadata of the data compiled, to include locations of critical assets owned or maintained by the CITY as well as regionally significant assets that are classified and as defined in s. 380.093(2)(a) 1-4, F.S. Task 2 Exposure and Sensitivity Analysis CONSULTANT will perform an exposure analysis to identify the depth of water caused by each sea level rise, storm surge, and/or flood scenario. Pursuant to s. 380.093, F.S., the following scenarios and standards will be used for the exposure analysis: 1) All analyses performed in North American Vertical Datum of 1988 (NAVD88). 2) Two local sea -level rise scenarios; the 2022 NOAA Intermediate -Low and Intermediate sea level rise projections. 3) Two planning horizons that include planning horizons for the years 2050 and 2080. 4) Local sea level data that has been interpolated between the two closest NOAA tide gauges. Local sea level data may be taken from one such gauge if the gauge has higher mean sea level. Data taken from an alternate gauge may be used with appropriate rationale and FDEP approval if it is publicly available or submitted to the FDEP. 5) Encompass the entire CITY and include all critical assets owned or maintained by the CITY. 6) The exposure analysis will use the most recent publicly available DEM which meets the defined minimum standard of 3 -meter cell size. 7) The "Modified Bathtub Model," pursuant to the 2017 NOAA publication Detailed Method for Mapping Sea Level Rise Inundation (NOAA, 2017), will be used to identify all potentially flooded areas. Pursuant to s. 380.093, F.S., the water surface depths (i.e., flood scenarios) used to evaluate assets will include the following data: 1) Tidal flooding, including future high tide flooding, must use thresholds published and provided by the FDEP. The analysis should also geographically display the number of tidal flood days expected for each scenario and planning horizons. 2) Current and future storm surge flooding, using publicly available NOAA or FEMA storm surge data. The initial storm surge event used must equal or exceed the current 100 -year Engineering Inspired Design. 0
