Is Issaquena County, MS in a flood zone?
FEMA's National Risk Index puts Issaquena County's flood hazard at the 10.2th percentile nationally — 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 3 years. That's a county-wide figure, not a per-address one — FEMA's parcel maps are a live lookup, not a bulk file.
Who actually carries the flood insurance FEMA requires
Out of 497 homes FEMA counts inside Issaquena County's mapped flood zone, 72 carry the flood policy federal law requires there — 14.5% compliance, short of full coverage. Across all residential structures in Issaquena County, not just the ones FEMA mandates, 10.5% carry an NFIP policy — most flood damage nationally happens outside the mapped high-risk zone, so that broader number matters too.
