Monroe County, OH Flood Zone & Flood Risk Data
Monroe County, OH flood risk explained
Flood hazard in Monroe County sits at the 50.9th 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 1.9 times a year. This describes the county, not any one street, FEMA only publishes exact parcel zones through a live map service.
Monroe County's flood-insurance compliance gap
7.8% of the homes FEMA requires to carry flood insurance in Monroe County, those inside the mapped Special Flood Hazard Area, actually have a policy in force: 20 policies against 255 mandated structures, which means a meaningful share of legally-required coverage simply isn't there.
