Is Jackson County, WV in a flood zone?
FEMA's National Risk Index puts Jackson County's flood hazard at the 75.8th percentile nationally — a middling flood hazard by national standards — driven by inland rivers and flash flooding rather than the coast — FEMA's model puts a flood event here at about 2.1 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.
Mandatory flood insurance compliance in Jackson County
Out of 886 homes FEMA counts inside Jackson County's mapped flood zone, 49 carry the flood policy federal law requires there — 5.5% compliance, short of full coverage. Across all residential structures in Jackson County, not just the ones FEMA mandates, 0.7% carry an NFIP policy — most flood damage nationally happens outside the mapped high-risk zone, so that broader number matters too.
