Richland County, WI flood risk explained
Flood hazard in Richland County sits at the 62.9th national percentile, below 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 1.2 times a year. County-wide, not parcel-specific: FEMA's real flood-zone map is queried live, never shipped as a download.
Richland County's flood-insurance compliance gap
Out of 105 homes FEMA counts inside Richland County's mapped flood zone, 12 carry the flood policy federal law requires there — 11.4% compliance, short of full coverage. Looking beyond the mandated zone, 0.3% of all residential structures in Richland County carry flood coverage voluntarily or otherwise — relevant because most NFIP claims nationally come from outside the mapped SFHA.
