Wood County, WI: flood risk, in FEMA's own numbers
On FEMA's National Risk Index, Wood County scores at the 77.7th 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 once every 1 years. County-wide, not parcel-specific: FEMA's real flood-zone map is queried live, never shipped as a download.
Mandatory flood insurance compliance in Wood County
17.9% of the homes FEMA requires to carry flood insurance in Wood County — those inside the mapped Special Flood Hazard Area — actually have a policy in force: 74 policies against 414 mandated structures, which means a meaningful share of legally-required coverage simply isn't there. Looking beyond the mandated zone, 0.4% of all residential structures in Wood County carry flood coverage voluntarily or otherwise — relevant because most NFIP claims nationally come from outside the mapped SFHA.
