Is Macon County, TN in a flood zone?
FEMA's National Risk Index puts Macon County's flood hazard at the 31.2th percentile nationally — among the lowest flood hazard in the country — 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. This describes the county, not any one street — FEMA only publishes exact parcel zones through a live map service.
Macon County's flood-insurance compliance gap
Out of 185 homes FEMA counts inside Macon County's mapped flood zone, 11 carry the flood policy federal law requires there — 6% compliance, short of full coverage. Across all residential structures in Macon 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.
