Uinta County, WY: flood risk, in FEMA's own numbers
On FEMA's National Risk Index, Uinta County scores at the 34.1th 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 28 years. This describes the county, not any one street — FEMA only publishes exact parcel zones through a live map service.
Who actually carries the flood insurance FEMA requires
Out of 619 homes FEMA counts inside Uinta County's mapped flood zone, 60 carry the flood policy federal law requires there — 9.7% compliance, short of full coverage. Looking beyond the mandated zone, 0.7% of all residential structures in Uinta County carry flood coverage voluntarily or otherwise — relevant because most NFIP claims nationally come from outside the mapped SFHA.
How Uinta County compares nationally
