Rich County, UT flood risk explained
Flood hazard in Rich County sits at the 3th national percentile, among the lowest flood hazard in the country; driven by inland rivers and flash flooding rather than the coast — FEMA's model puts a flood event here at about once every 9 years. County-wide, not parcel-specific: FEMA's real flood-zone map is queried live, never shipped as a download.
Rich County's flood-insurance compliance gap
FEMA hasn't published a residential structure count for Rich County's mapped flood zone, so a reliable mandatory-compliance percentage can't be computed here — see the data quality guide for why this gap exists for roughly a quarter of US counties. Looking beyond the mandated zone, 0.1% of all residential structures in Rich County carry flood coverage voluntarily or otherwise — relevant because most NFIP claims nationally come from outside the mapped SFHA.
Rich County against the rest of the country
Among the 3144 US counties FEMA scores for flood hazard, Rich County ranks 3055 — 1 being the highest hazard nationally — and 2978 by population among all 3144 counties covered here, where 1 is the largest. Rich County, Utah is home to about 2,752 people across 1,028.758 square miles of land.
