Grant County, IN Flood Zone & Flood Risk Data
Grant County, IN flood risk explained
Flood hazard in Grant County sits at the 73.4th national percentile, a middling flood hazard by national standards; driven by inland rivers and flash flooding rather than the coast, FEMA's model puts a flood event here at about once every 2 years. County-wide, not parcel-specific: FEMA's real flood-zone map is queried live, never shipped as a download.
Grant County's flood-insurance compliance gap
11.3% of the homes FEMA requires to carry flood insurance in Grant County, those inside the mapped Special Flood Hazard Area, actually have a policy in force: 44 policies against 388 mandated structures, which means a meaningful share of legally-required coverage simply isn't there. Looking beyond the mandated zone, 0.2% of all residential structures in Grant County carry flood coverage voluntarily or otherwise, relevant because most NFIP claims nationally come from outside the mapped SFHA.
