How much flood risk does Caswell County actually carry?
Caswell County lands at the 37.7th 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 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.
Caswell County's flood-insurance compliance gap
Homes with a federally backed mortgage inside Caswell County's mapped high-risk flood zone (the Special Flood Hazard Area, or SFHA) are legally required to carry an NFIP flood policy. In practice, 3.3% of them do — 1 active policies against 30 structures FEMA counts in that zone, leaving a real compliance gap. Across all residential structures in Caswell County, not just the ones FEMA mandates, 0% carry an NFIP policy — most flood damage nationally happens outside the mapped high-risk zone, so that broader number matters too.
