Douglas County, NV: flood risk, in FEMA's own numbers
On FEMA's National Risk Index, Douglas County scores at the 73.8th percentile for flood hazard, rated "Relatively Moderate" — a middling flood hazard by national standards. 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 1 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 Douglas County
Out of 1,571 homes FEMA counts inside Douglas County's mapped flood zone, 495 carry the flood policy federal law requires there — 31.5% compliance, short of full coverage. Looking beyond the mandated zone, 3% of all residential structures in Douglas County carry flood coverage voluntarily or otherwise — relevant because most NFIP claims nationally come from outside the mapped SFHA.
