Washita County, OK: flood risk, in FEMA's own numbers
On FEMA's National Risk Index, Washita County scores at the 19.8th percentile for flood hazard, rated "Very Low" — among the lowest flood hazard in the country. 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 once every 2 years. This describes the county, not any one street — FEMA only publishes exact parcel zones through a live map service.
Washita County's flood-insurance compliance gap
Out of 66 homes FEMA counts inside Washita County's mapped flood zone, 10 carry the flood policy federal law requires there — 15.2% compliance, short of full coverage. Looking beyond the mandated zone, 0.2% of all residential structures in Washita County carry flood coverage voluntarily or otherwise — relevant because most NFIP claims nationally come from outside the mapped SFHA.
Where Washita County ranks
Among the 3144 US counties FEMA scores for flood hazard, Washita County ranks 2564 — 1 being the highest hazard nationally — and 2355 by population among all 3144 counties covered here, where 1 is the largest. About 10,839 people live in Washita County, Oklahoma, spread over 1,003.089 square miles.
