Kenosha County, WI: flood risk, in FEMA's own numbers
On FEMA's National Risk Index, Kenosha County scores at the 76.6th percentile for flood hazard, rated "Relatively Moderate" — a middling flood hazard by national standards. The hazard here is driven by inland rivers and flash flooding rather than the coast — FEMA's model puts a flood event here at about 2 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
14.9% of the homes FEMA requires to carry flood insurance in Kenosha County — those inside the mapped Special Flood Hazard Area — actually have a policy in force: 91 policies against 612 mandated structures, which means a meaningful share of legally-required coverage simply isn't there. Looking beyond the mandated zone, 0.3% of all residential structures in Kenosha County carry flood coverage voluntarily or otherwise — relevant because most NFIP claims nationally come from outside the mapped SFHA.
