Perry County, IN flood risk explained
Flood hazard in Perry County sits at the 49th 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 2.5 times a year. County-wide, not parcel-specific: FEMA's real flood-zone map is queried live, never shipped as a download.
Mandatory flood insurance compliance in Perry County
9.7% 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: 32 policies against 330 mandated structures, which means a meaningful share of legally-required coverage simply isn't there. Looking beyond the mandated zone, 0.5% 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.
