Is Adams County, MS in a flood zone?
FEMA's National Risk Index puts Adams County's flood hazard at the 59th percentile nationally — 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 1.4 times a year. That's a county-wide figure, not a per-address one — FEMA's parcel maps are a live lookup, not a bulk file.
Adams County's flood-insurance compliance gap
Out of 106 homes FEMA counts inside Adams County's mapped flood zone, 13 carry the flood policy federal law requires there — 12.3% compliance, short of full coverage. Across all residential structures in Adams County, not just the ones FEMA mandates, 0.3% carry an NFIP policy — most flood damage nationally happens outside the mapped high-risk zone, so that broader number matters too.
