How much flood risk does Hardin County actually carry?
Hardin County lands at the 52.9th percentile of FEMA's National Risk Index for flooding, "Relatively Low" territory — below the national norm for flood hazard — with the hazard driven by inland rivers and flash flooding rather than the coast — FEMA's model puts a flood event here at about 1.7 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 Hardin County
Out of 246 homes FEMA counts inside Hardin County's mapped flood zone, 29 carry the flood policy federal law requires there — 11.8% compliance, short of full coverage. Across all residential structures in Hardin County, not just the ones FEMA mandates, 0.4% carry an NFIP policy — most flood damage nationally happens outside the mapped high-risk zone, so that broader number matters too.
