Is Long County, GA in a flood zone?
FEMA's National Risk Index puts Long County's flood hazard at the 20th percentile nationally — among the lowest flood hazard in the country — driven by coastal storm surge rather than inland rivers — FEMA's model puts a surge event here at about once every 83 years. 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 Long County
Out of 317 homes FEMA counts inside Long County's mapped flood zone, 149 carry the flood policy federal law requires there — 47% compliance, short of full coverage. Across all residential structures in Long County, not just the ones FEMA mandates, 3.7% carry an NFIP policy — most flood damage nationally happens outside the mapped high-risk zone, so that broader number matters too.
