Nash County, NC: flood risk, in FEMA's own numbers
On FEMA's National Risk Index, Nash County scores at the 82.5th percentile for flood hazard, rated "Relatively Moderate" — a middling flood hazard by national standards. The hazard here is driven by inland rivers and flash flooding rather than the coast — FEMA's model puts a flood event here at about 1 times a year. This describes the county, not any one street — FEMA only publishes exact parcel zones through a live map service.
Mandatory flood insurance compliance in Nash County
Out of 741 homes FEMA counts inside Nash County's mapped flood zone, 366 carry the flood policy federal law requires there — 49.4% compliance, short of full coverage. Looking beyond the mandated zone, 1.4% of all residential structures in Nash County carry flood coverage voluntarily or otherwise — relevant because most NFIP claims nationally come from outside the mapped SFHA.
