Wilson County, NC flood risk explained
Flood hazard in Wilson County sits at the 77.2th national percentile, a middling flood hazard by national standards; 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.
