Is Itawamba County, MS in a flood zone?
FEMA's National Risk Index puts Itawamba County's flood hazard at the 28.2th 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 2 years. County-wide, not parcel-specific: FEMA's real flood-zone map is queried live, never shipped as a download.
Who actually carries the flood insurance FEMA requires
Out of 119 homes FEMA counts inside Itawamba County's mapped flood zone, 6 carry the flood policy federal law requires there — 5% compliance, short of full coverage. Across all residential structures in Itawamba County, not just the ones FEMA mandates, 0.2% carry an NFIP policy — most flood damage nationally happens outside the mapped high-risk zone, so that broader number matters too.
