Sequoyah County, OK: flood risk, in FEMA's own numbers
On FEMA's National Risk Index, Sequoyah County scores at the 73.6th percentile for flood hazard, rated "Relatively Moderate" — a middling flood hazard by national standards. 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 2 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.
Mandatory flood insurance compliance in Sequoyah County
Out of 741 homes FEMA counts inside Sequoyah County's mapped flood zone, 54 carry the flood policy federal law requires there — 7.3% compliance, short of full coverage. Looking beyond the mandated zone, 0.4% of all residential structures in Sequoyah County carry flood coverage voluntarily or otherwise — relevant because most NFIP claims nationally come from outside the mapped SFHA.
