Is Iowa County, IA in a flood zone?
FEMA's National Risk Index puts Iowa County's flood hazard at the 32.6th percentile nationally — among the lowest flood hazard in the country — driven by inland rivers and flash flooding rather than the coast — FEMA's model puts a flood event here at about 1.9 times a year. This describes the county, not any one street — FEMA only publishes exact parcel zones through a live map service.
Iowa County's flood-insurance compliance gap
26.4% of the homes FEMA requires to carry flood insurance in Iowa County — those inside the mapped Special Flood Hazard Area — actually have a policy in force: 65 policies against 246 mandated structures, which means a meaningful share of legally-required coverage simply isn't there. Across all residential structures in Iowa 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.
