Sanpete County, UT: flood risk, in FEMA's own numbers
On FEMA's National Risk Index, Sanpete County scores at the 24.5th 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. County-wide, not parcel-specific: FEMA's real flood-zone map is queried live, never shipped as a download.
Sanpete County's flood-insurance compliance gap
Homes with a federally backed mortgage inside Sanpete 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, 21% of them do — 66 active policies against 315 structures FEMA counts in that zone, leaving a real compliance gap. Looking beyond the mandated zone, 1% of all residential structures in Sanpete County carry flood coverage voluntarily or otherwise — relevant because most NFIP claims nationally come from outside the mapped SFHA.

Among the 3144 US counties FEMA scores for flood hazard, Sanpete County ranks 2417 — 1 being the highest hazard nationally — and 1424 by population among all 3144 counties covered here, where 1 is the largest. About 30,732 people live in Sanpete County, Utah, spread over 1,589.816 square miles.
