How much flood risk does Perry County actually carry?
Perry County lands at the 32.1th percentile of FEMA's National Risk Index for flooding, "Very Low" territory — among the lowest flood hazard in the country — with the hazard driven by inland rivers and flash flooding rather than the coast — FEMA's model puts a flood event here at about 2.5 times a year. County-wide, not parcel-specific: FEMA's real flood-zone map is queried live, never shipped as a download.
Perry County's flood-insurance compliance gap
7.4% of the homes FEMA requires to carry flood insurance in Perry County — those inside the mapped Special Flood Hazard Area — actually have a policy in force: 14 policies against 190 mandated structures, which means a meaningful share of legally-required coverage simply isn't there. Across all residential structures in Perry County, not just the ones FEMA mandates, 0.2% carry an NFIP policy — most flood damage nationally happens outside the mapped high-risk zone, so that broader number matters too.
