Fort Bend County, TX: flood risk, in FEMA's own numbers
On FEMA's National Risk Index, Fort Bend County scores at the 97.6th percentile for flood hazard, rated "Relatively High" — well above the national norm for flood hazard. The hazard here is driven by inland rivers and flash flooding rather than the coast — FEMA's model puts a flood event here at about 1.7 times a year. This describes the county, not any one street — FEMA only publishes exact parcel zones through a live map service.
Fort Bend County's flood-insurance compliance gap
Out of 6,535 homes FEMA counts inside Fort Bend County's mapped flood zone, 2,739 carry the flood policy federal law requires there — 41.9% compliance, short of full coverage. Looking beyond the mandated zone, 15.5% of all residential structures in Fort Bend County carry flood coverage voluntarily or otherwise — relevant because most NFIP claims nationally come from outside the mapped SFHA.
