How much flood risk does Franklin County actually carry?
Franklin County lands at the 56th 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 once every 1 years. This describes the county, not any one street — FEMA only publishes exact parcel zones through a live map service.
Mandatory flood insurance compliance in Franklin County
Out of 67 homes FEMA counts inside Franklin County's mapped flood zone, 20 carry the flood policy federal law requires there — 29.9% compliance, short of full coverage. Across all residential structures in Franklin County, not just the ones FEMA mandates, 0.3% carry an NFIP policy — most flood damage nationally happens outside the mapped high-risk zone, so that broader number matters too.
