How much flood risk does Prentiss County actually carry?
Prentiss County lands at the 40.6th percentile of FEMA's National Risk Index for flooding, "Relatively Low" territory — below the national norm for flood hazard — with the 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. That's a county-wide figure, not a per-address one — FEMA's parcel maps are a live lookup, not a bulk file.
Prentiss County's flood-insurance compliance gap
Out of 211 homes FEMA counts inside Prentiss County's mapped flood zone, 3 carry the flood policy federal law requires there — 1.4% compliance, short of full coverage. Across all residential structures in Prentiss County, not just the ones FEMA mandates, 0.1% carry an NFIP policy — most flood damage nationally happens outside the mapped high-risk zone, so that broader number matters too.
