Is Anderson County, KY in a flood zone?
FEMA's National Risk Index puts Anderson County's flood hazard at the 34.4th 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 once every 1 years. This describes the county, not any one street — FEMA only publishes exact parcel zones through a live map service.
Who actually carries the flood insurance FEMA requires
18.6% of the homes FEMA requires to carry flood insurance in Anderson County — those inside the mapped Special Flood Hazard Area — actually have a policy in force: 30 policies against 161 mandated structures, which means a meaningful share of legally-required coverage simply isn't there. Across all residential structures in Anderson County, not just the ones FEMA mandates, 0.4% carry an NFIP policy — most flood damage nationally happens outside the mapped high-risk zone, so that broader number matters too.
