Is Clallam County, WA in a flood zone?
FEMA's National Risk Index puts Clallam County's flood hazard at the 75th 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 once every 5 years. County-wide, not parcel-specific: FEMA's real flood-zone map is queried live, never shipped as a download.
Clallam County's flood-insurance compliance gap
Clallam County is one of the counties where FEMA's own denominator for mandated flood-zone structures is missing, so no compliance rate is shown rather than a guessed one — the data quality guide covers how common this is. Across all residential structures in Clallam County, not just the ones FEMA mandates, 0.8% carry an NFIP policy — most flood damage nationally happens outside the mapped high-risk zone, so that broader number matters too.
