Perry County, OH flood risk explained
Flood hazard in Perry County sits at the 47th national percentile, 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 1.6 times a year. That's a county-wide figure, not a per-address one — FEMA's parcel maps are a live lookup, not a bulk file.
Perry County's flood-insurance compliance gap
13.4% 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: 81 policies against 606 mandated structures, which means a meaningful share of legally-required coverage simply isn't there. Looking beyond the mandated zone, 0.6% of all residential structures in Perry County carry flood coverage voluntarily or otherwise — relevant because most NFIP claims nationally come from outside the mapped SFHA.
How Perry County compares nationally
Among the 3144 US counties FEMA scores for flood hazard, Perry County ranks 1727 — 1 being the highest hazard nationally — and 1298 by population among all 3144 counties covered here, where 1 is the largest. Perry County, Ohio is home to about 35,682 people across 407.94 square miles of land.
