How much flood risk does Henry County actually carry?
Henry County lands at the 27.3th 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 once every 1 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 Henry County
Out of 84 homes FEMA counts inside Henry County's mapped flood zone, 24 carry the flood policy federal law requires there — 28.6% compliance, short of full coverage. Across all residential structures in Henry County, not just the ones FEMA mandates, 0.5% carry an NFIP policy — most flood damage nationally happens outside the mapped high-risk zone, so that broader number matters too.
