City updates vulnerability assessment, identifies focus areas and 20 grant-ready projects under Resilient Florida planning grant
Summary
Gainesville staff and consultants updated a hydrologic model and exposure analysis under a Resilient Florida planning grant, identified focus areas and will screen up to 30 adaptation projects (10 city / 10 GRU shortlist) to pursue implementation grants; final deliverables are due in June 2025.
City resiliency staff and consultant Jones Edmunds reported to the Commission on Feb. 20 that the Resilient Florida planning grant update to the regional vulnerability assessment included a refined hydraulic model, new lake bathymetry and updated soils data, and that the team has mapped critical assets exposed to increasingly extreme rainfall events.
Consultant Brett Cunningham said the project re-used and refined the Alachua County vulnerability assessment model, ran the required design storm scenarios (baseline and future change-factor scenarios for 2040 and 2070) and produced exposure and sensitivity analyses for the city’s roughly 9,500 critical assets (excluding roads). The project uses a combined exposure–sensitivity–adaptive-capacity method to rank asset vulnerability and then overlays equity indicators (CDC/ATSDR social vulnerability datasets) to create “focus areas.” Two focus areas were identified in the city; one central focus area had a clustering of critical municipal assets and utility infrastructure.
Staff said the planning grant now moves to the adaptation screening phase. The team will screen up to 30 candidate adaptation projects (15 Public Works and 15 GRU), reduce those to a 20-project shortlist (10 city, 10 GRU), develop concept-level cost estimates and submit grant-ready project descriptions. Resilient Florida implementation grants typically fund design and construction for eligible public infrastructure projects (historically up to 50% of eligible costs, and competitive). Staff said they expect to complete the planning deliverables by June 2025 so that projects can be submitted in the next grant window.
Commissioners asked for examples of adaptation measures; staff said potential measures would include flood-storage or conveyance projects, raising electrical panels or other hardening of utility infrastructure, localized floodproofing and drainage improvements. Staff said priority would go to projects inside the identified focus areas because the Resilient Florida scoring rubric awards additional points to projects that are in those focus geographies. The department also confirmed the scope is flood-focused under the grant, not the broader hazard set that Alachua County modeled (county earlier included wildfire, water-supply and other vulnerabilities).
