Is Dane County, WI in a flood zone?

FEMA's National Risk Index puts Dane County's flood hazard at the 94.3th percentile nationally — well above the national norm for flood hazard — driven by inland rivers and flash flooding rather than the coast — FEMA's model puts a flood event here at about 2.1 times a year. This describes the county, not any one street — FEMA only publishes exact parcel zones through a live map service.

Who actually carries the flood insurance FEMA requires

Out of 757 homes FEMA counts inside Dane County's mapped flood zone, 131 carry the flood policy federal law requires there — 17.3% compliance, short of full coverage. Across all residential structures in Dane 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.
