How much flood risk does Appomattox County actually carry?
Appomattox County lands at the 14.7th percentile of FEMA's National Risk Index for flooding, "Very Low" territory — among the lowest flood hazard in the country — with the hazard driven by inland rivers and flash flooding rather than the coast — FEMA's model puts a flood event here at about 1.1 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.
Appomattox County's flood-insurance compliance gap
Out of 38 homes FEMA counts inside Appomattox County's mapped flood zone, 5 carry the flood policy federal law requires there — 13.2% compliance, short of full coverage. Across all residential structures in Appomattox 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.
