Payette County, ID flood risk explained
Flood hazard in Payette County sits at the 33.9th 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 4 years. County-wide, not parcel-specific: FEMA's real flood-zone map is queried live, never shipped as a download.
Payette County's flood-insurance compliance gap
FEMA hasn't published a residential structure count for Payette 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, 0.2% of all residential structures in Payette County carry flood coverage voluntarily or otherwise — relevant because most NFIP claims nationally come from outside the mapped SFHA.
