Florida top concern
Hurricanes, sea-level rise, sinkholes
Florida has the most extensive FEMA NFHL coverage in the US — coastal AE/VE zones plus inland AE driven by storm-surge modeling. Citizens Property Insurance Corp absorbs much of the high-risk private-market shedding. Radon risk concentrates in central FL limestone karst counties; sinkholes are tracked by FDEP separately.
