Kewaunee County, WI: flood risk, in FEMA's own numbers
On FEMA's National Risk Index, Kewaunee County scores at the 30.2th percentile for flood hazard, rated "Very Low" — among the lowest flood hazard in the country. The hazard here is split between inland river flooding (about once every 1 years) and coastal storm surge (about once every 65 years). County-wide, not parcel-specific: FEMA's real flood-zone map is queried live, never shipped as a download.
Who actually carries the flood insurance FEMA requires
FEMA hasn't published a residential structure count for Kewaunee County's mapped flood zone, so a reliable mandatory-compliance percentage can't be computed here — see the data quality guide for why this gap exists for roughly a quarter of US counties. Looking beyond the mandated zone, 0.3% of all residential structures in Kewaunee County carry flood coverage voluntarily or otherwise — relevant because most NFIP claims nationally come from outside the mapped SFHA.

Your street may differ from Kewaunee County's average
