Is Iron County, MO in a flood zone?
FEMA's National Risk Index puts Iron County's flood hazard at the 64.5th percentile nationally — below the national norm for flood hazard — driven by inland rivers and flash flooding rather than the coast — FEMA's model puts a flood event here at about once every 1 years. This describes the county, not any one street — FEMA only publishes exact parcel zones through a live map service.
Iron County's flood-insurance compliance gap
2.9% of the homes FEMA requires to carry flood insurance in Iron County — those inside the mapped Special Flood Hazard Area — actually have a policy in force: 32 policies against 1,087 mandated structures, which means a meaningful share of legally-required coverage simply isn't there. Across all residential structures in Iron County, not just the ones FEMA mandates, 0.5% carry an NFIP policy — most flood damage nationally happens outside the mapped high-risk zone, so that broader number matters too.
Iron County against the rest of the country
