Is Perry County, TN in a flood zone?
FEMA's National Risk Index puts Perry County's flood hazard at the 47.1th 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.
Perry County's flood-insurance compliance gap
Homes with a federally backed mortgage inside Perry 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, 10.9% of them do — 50 active policies against 459 structures FEMA counts in that zone, leaving a real compliance gap. Across all residential structures in Perry County, not just the ones FEMA mandates, 1.4% carry an NFIP policy — most flood damage nationally happens outside the mapped high-risk zone, so that broader number matters too.
