Is Lewis County, KY in a flood zone?
FEMA's National Risk Index puts Lewis County's flood hazard at the 64.9th 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 1.9 times a year. County-wide, not parcel-specific: FEMA's real flood-zone map is queried live, never shipped as a download.
Lewis County's flood-insurance compliance gap
Homes with a federally backed mortgage inside Lewis County's mapped high-risk flood zone (the Special Flood Hazard Area, or SFHA) are legally required to carry an NFIP flood policy. In practice, 7.4% of them do — 40 active policies against 544 structures FEMA counts in that zone, leaving a real compliance gap. Across all residential structures in Lewis County, 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.
