Is Rockingham County, VA in a flood zone?
FEMA's National Risk Index puts Rockingham County's flood hazard at the 84.6th 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 2.4 times a year. This describes the county, not any one street — FEMA only publishes exact parcel zones through a live map service.
Who actually carries the flood insurance FEMA requires
Out of 1,350 homes FEMA counts inside Rockingham County's mapped flood zone, 196 carry the flood policy federal law requires there — 14.5% compliance, short of full coverage. Across all residential structures in Rockingham 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.
