Ste. Genevieve County, MO flood risk explained
Flood hazard in Ste. Genevieve County sits at the 52.6th 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 once every 1 years. 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 195 homes FEMA counts inside Ste. Genevieve County's mapped flood zone, 24 carry the flood policy federal law requires there — 12.3% compliance, short of full coverage. Looking beyond the mandated zone, 0.5% of all residential structures in Ste. Genevieve County carry flood coverage voluntarily or otherwise — relevant because most NFIP claims nationally come from outside the mapped SFHA.
