How much flood risk does Scioto County actually carry?
Scioto County lands at the 82th percentile of FEMA's National Risk Index for flooding, "Relatively Moderate" territory — a middling flood hazard by national standards — with the hazard driven by inland rivers and flash flooding rather than the coast — FEMA's model puts a flood event here at about 3.5 times a year. This describes the county, not any one street — FEMA only publishes exact parcel zones through a live map service.
Scioto County's flood-insurance compliance gap
9.8% of the homes FEMA requires to carry flood insurance in Scioto County — those inside the mapped Special Flood Hazard Area — actually have a policy in force: 163 policies against 1,660 mandated structures, which means a meaningful share of legally-required coverage simply isn't there. Across all residential structures in Scioto County, not just the ones FEMA mandates, 0.7% carry an NFIP policy — most flood damage nationally happens outside the mapped high-risk zone, so that broader number matters too.
