Carroll County, MS flood risk explained
Flood hazard in Carroll County sits at the 20.4th national percentile, among the lowest flood hazard in the country; 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.
Carroll County's flood-insurance compliance gap
Out of 56 homes FEMA counts inside Carroll County's mapped flood zone, 11 carry the flood policy federal law requires there — 19.6% compliance, short of full coverage. Looking beyond the mandated zone, 0.3% of all residential structures in Carroll County carry flood coverage voluntarily or otherwise — relevant because most NFIP claims nationally come from outside the mapped SFHA.
