How much flood risk does Nome Census Area actually carry?
Nome Census Area lands at the 5.7th percentile of FEMA's National Risk Index for flooding, "No Rating" territory — not rated by FEMA’s risk index — with the hazard 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.
Nome Census Area's flood-insurance compliance gap
Nome Census Area 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 Nome Census Area, not just the ones FEMA mandates, 0.9% carry an NFIP policy — most flood damage nationally happens outside the mapped high-risk zone, so that broader number matters too.
