How much flood risk does Wayne County actually carry?
Wayne County lands at the 68.6th 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 3.8 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.
Wayne County's flood-insurance compliance gap
Out of 667 homes FEMA counts inside Wayne County's mapped flood zone, 48 carry the flood policy federal law requires there — 7.2% compliance, short of full coverage. Across all residential structures in Wayne County, not just the ones FEMA mandates, 1% carry an NFIP policy — most flood damage nationally happens outside the mapped high-risk zone, so that broader number matters too.
