How much flood risk does Racine County actually carry?
Racine County lands at the 85.7th 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 1.6 times a year. That's a county-wide figure, not a per-address one — FEMA's parcel maps are a live lookup, not a bulk file.
Racine County's flood-insurance compliance gap
Out of 465 homes FEMA counts inside Racine County's mapped flood zone, 212 carry the flood policy federal law requires there — 45.6% compliance, short of full coverage. Across all residential structures in Racine County, not just the ones FEMA mandates, 0.5% carry an NFIP policy — most flood damage nationally happens outside the mapped high-risk zone, so that broader number matters too.
