FEMA flood maps leave North Carolina homeowners uninsured after Hurricane Helene

On September 27, 2024, a flash‑flood emergency alert prompted mandatory evacuation for residents of Swannanoa, a community just outside Asheville, North Carolina. The Swannanoa River rose to historic levels after Hurricane Helene dumped heavy rain on the Appalachian region, submerging homes up to the attic. Liz Barker, a midwife and single mother, described the damage as "catastrophic" and noted that only one of the 24 flooded houses on her street had flood insurance.

Experts say the lack of coverage stems from misunderstandings of FEMA’s flood maps. Barker’s home was not located in a Special Flood Hazard Area, so federal flood insurance was not required. Nationwide, fewer than 1% of homes in Buncombe County carried such insurance at the time of the storm, leaving many homeowners exposed.

The situation highlights how FEMA’s mapping system can influence insurance decisions and leave millions of Americans without protection against severe flooding.
