Mohave County, AZ: flood risk, in FEMA's own numbers
On FEMA's National Risk Index, Mohave County scores at the 97.1th percentile for flood hazard, rated "Relatively High" — well above the national norm for flood hazard. 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 10.4 times a year. County-wide, not parcel-specific: FEMA's real flood-zone map is queried live, never shipped as a download.
Mandatory flood insurance compliance in Mohave County
Out of 2,464 homes FEMA counts inside Mohave County's mapped flood zone, 453 carry the flood policy federal law requires there — 18.4% compliance, short of full coverage. Looking beyond the mandated zone, 0.5% of all residential structures in Mohave County carry flood coverage voluntarily or otherwise — relevant because most NFIP claims nationally come from outside the mapped SFHA.
