Converse County, WY: flood risk, in FEMA's own numbers
On FEMA's National Risk Index, Converse County scores at the 40.4th 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 once every 6 years. 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 Converse County
Out of 377 homes FEMA counts inside Converse County's mapped flood zone, 16 carry the flood policy federal law requires there — 4.2% compliance, short of full coverage. Looking beyond the mandated zone, 0.3% of all residential structures in Converse County carry flood coverage voluntarily or otherwise — relevant because most NFIP claims nationally come from outside the mapped SFHA.
