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.

Among the 3144 US counties FEMA scores for flood hazard, Grant County ranks 874 — 1 being the highest hazard nationally — and 823 by population among all 3144 counties covered here, where 1 is the largest. Grant County, Indiana covers 414.089 square miles and counts roughly 66,458 residents.
