Texas context
Hurricanes (Gulf coast), flooding, drought
Texas Gulf coast has the largest FEMA VE/AE coverage of any state. Inland flooding (Hurricane Harvey 2017) triggered FIRM panel revisions for Houston metro. Drought + induced seismicity affect EPA SDWIS compliance in West Texas. Tornado risk in the Panhandle.
Florida context
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.
