Is Darlington County, SC in a flood zone?
FEMA's National Risk Index puts Darlington County's flood hazard at the 64.2th percentile nationally — below the national norm for flood hazard — driven by inland rivers and flash flooding rather than the coast — FEMA's model puts a flood event here at about once every 2 years. This describes the county, not any one street — FEMA only publishes exact parcel zones through a live map service.
Who actually carries the flood insurance FEMA requires
Out of 165 homes FEMA counts inside Darlington County's mapped flood zone, 34 carry the flood policy federal law requires there — 20.6% compliance, short of full coverage. Across all residential structures in Darlington 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.
