Is La Paz County, AZ in a flood zone?
FEMA's National Risk Index puts La Paz County's flood hazard at the 91.5th percentile nationally — a middling flood hazard by national standards — driven by inland rivers and flash flooding rather than the coast — FEMA's model puts a flood event here at about 2.9 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 La Paz County
6.8% of the homes FEMA requires to carry flood insurance in La Paz County — those inside the mapped Special Flood Hazard Area — actually have a policy in force: 188 policies against 2,781 mandated structures, which means a meaningful share of legally-required coverage simply isn't there. Across all residential structures in La Paz County, not just the ones FEMA mandates, 1.5% carry an NFIP policy — most flood damage nationally happens outside the mapped high-risk zone, so that broader number matters too.
