Bethel Census Area, AK flood risk explained
Flood hazard in Bethel Census Area sits at the 9.6th national percentile, not rated by FEMA’s risk index; split between inland river flooding (about once every 200 years) and coastal storm surge (about once every Infinity years). This describes the county, not any one street — FEMA only publishes exact parcel zones through a live map service.
Bethel Census Area's flood-insurance compliance gap
FEMA hasn't published a residential structure count for Bethel Census Area'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, 2.4% of all residential structures in Bethel Census Area carry flood coverage voluntarily or otherwise — relevant because most NFIP claims nationally come from outside the mapped SFHA.

Among the 3144 US counties FEMA scores for flood hazard, Bethel Census Area ranks 2859 — 1 being the highest hazard nationally — and 1919 by population among all 3144 counties covered here, where 1 is the largest.
