Apalachee Nine-County Regional Vulnerability Assessment

Halff partnered with the Apalachee Regional Planning Council (ARPC) to conduct a comprehensive climate vulnerability assessment across nine counties in Florida’s Apalachee Region. The regional assessment evaluated more than 17,000 critical and regionally significant assets against current and future climate hazards, including tidal flooding, storm surge, sea-level rise, extreme rainfall and compound flooding.

Using GIS analysis, hazard modeling and site-specific evaluations, Halff identified infrastructure vulnerabilities and developed a comprehensive technical report supported by more than 90 maps. The assessment provides a consistent, data-driven understanding of regional exposure and highlights vulnerabilities that may affect critical infrastructure, public services and community assets.

The resulting assessment equips regional and local governments with actionable information to prioritize infrastructure improvements, pursue resilience funding and guide future hazard mitigation and climate adaptation strategies. By establishing a shared technical foundation across nine counties, the project supports coordinated regional planning and more informed resilience investments.
