How much flood risk does Vermillion County actually carry?
Vermillion County lands at the 33th percentile of FEMA's National Risk Index for flooding, "Very Low" territory — among the lowest flood hazard in the country — with the hazard driven by inland rivers and flash flooding rather than the coast — FEMA's model puts a flood event here at about 3.9 times a year. County-wide, not parcel-specific: FEMA's real flood-zone map is queried live, never shipped as a download.
Vermillion County's flood-insurance compliance gap
14.8% of the homes FEMA requires to carry flood insurance in Vermillion County — those inside the mapped Special Flood Hazard Area — actually have a policy in force: 45 policies against 304 mandated structures, which means a meaningful share of legally-required coverage simply isn't there. Across all residential structures in Vermillion County, not just the ones FEMA mandates, 0.6% carry an NFIP policy — most flood damage nationally happens outside the mapped high-risk zone, so that broader number matters too.
