Jasper County, TX: flood risk, in FEMA's own numbers
On FEMA's National Risk Index, Jasper County scores at the 55th percentile for flood hazard, rated "Relatively Low" — below 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 1.1 times a year. That's a county-wide figure, not a per-address one — FEMA's parcel maps are a live lookup, not a bulk file.
Jasper County's flood-insurance compliance gap
Out of 708 homes FEMA counts inside Jasper County's mapped flood zone, 134 carry the flood policy federal law requires there — 18.9% compliance, short of full coverage. Looking beyond the mandated zone, 2.4% of all residential structures in Jasper County carry flood coverage voluntarily or otherwise — relevant because most NFIP claims nationally come from outside the mapped SFHA.
Where Jasper County ranks
Among the 3144 US counties FEMA scores for flood hazard, Jasper County ranks 1480 — 1 being the highest hazard nationally — and 1371 by population among all 3144 counties covered here, where 1 is the largest. Jasper County, Texas is home to about 32,907 people across 938.655 square miles of land.
