How much flood risk does Vigo County actually carry?
Vigo County lands at the 85.1th percentile of FEMA's National Risk Index for flooding, "Relatively Moderate" territory — a middling flood hazard by national standards — with the hazard driven by inland rivers and flash flooding rather than the coast — FEMA's model puts a flood event here at about 4 times a year. County-wide, not parcel-specific: FEMA's real flood-zone map is queried live, never shipped as a download.
Vigo County's flood-insurance compliance gap
Out of 1,676 homes FEMA counts inside Vigo County's mapped flood zone, 402 carry the flood policy federal law requires there — 24% compliance, short of full coverage. Across all residential structures in Vigo County, not just the ones FEMA mandates, 1.2% carry an NFIP policy — most flood damage nationally happens outside the mapped high-risk zone, so that broader number matters too.
Where Vigo County ranks
