Washakie County, WY: flood risk, in FEMA's own numbers

On FEMA's National Risk Index, Washakie County scores at the 48.6th 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 2 years. County-wide, not parcel-specific: FEMA's real flood-zone map is queried live, never shipped as a download.

Mandatory flood insurance compliance in Washakie County

Homes with a federally backed mortgage inside Washakie County's mapped high-risk flood zone (the Special Flood Hazard Area, or SFHA) are legally required to carry an NFIP flood policy. In practice, 9.1% of them do — 4 active policies against 44 structures FEMA counts in that zone, leaving a real compliance gap. Looking beyond the mandated zone, 0.2% of all residential structures in Washakie County carry flood coverage voluntarily or otherwise — relevant because most NFIP claims nationally come from outside the mapped SFHA.
