Is Marshall County, KY in a flood zone?
FEMA's National Risk Index puts Marshall County's flood hazard at the 47.3th 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 2.1 times a year. This describes the county, not any one street — FEMA only publishes exact parcel zones through a live map service.
Marshall County's flood-insurance compliance gap
16.7% of the homes FEMA requires to carry flood insurance in Marshall County — those inside the mapped Special Flood Hazard Area — actually have a policy in force: 59 policies against 354 mandated structures, which means a meaningful share of legally-required coverage simply isn't there. Across all residential structures in Marshall County, not just the ones FEMA mandates, 0.6% carry an NFIP policy — most flood damage nationally happens outside the mapped high-risk zone, so that broader number matters too.
