FEMA flood zone rules in Roswell, GA — also called floodplain regulations or special flood hazard area (SFHA) rules — determine flood insurance requirements and elevation standards for new construction.
Properties along the Chattahoochee River and Big Creek in Roswell sit within FEMA Special Flood Hazard Areas (Zone AE). New construction or substantial improvement in those zones requires elevation to at least 1 foot above Base Flood Elevation (BFE), a floodplain development permit, and an Elevation Certificate.
Roswell participates in the National Flood Insurance Program (NFIP) and uses FEMA Flood Insurance Rate Maps (FIRMs) to identify Special Flood Hazard Areas. The Chattahoochee River corridor along Riverside Park and Azalea Drive, plus Big Creek and Vickery Creek floodplains, are mapped Zone AE with established BFEs. Roswell's floodplain ordinance requires the lowest floor of any new structure (including basement) in Zone AE to be elevated at least 1 foot above BFE - 'freeboard' that exceeds the federal minimum. Substantial improvements (renovation cost exceeding 50% of pre-improvement market value) trigger the same elevation requirement for the entire structure. A floodplain development permit is required for any work in the SFHA, including fill, grading, and accessory structures. An Elevation Certificate by a Georgia-licensed surveyor or engineer is required at final inspection.
Building in a FEMA Special Flood Hazard Area without a floodplain permit is a serious violation that can result in NFIP sanctions, denial of flood insurance, and Municipal Court fines up to $1,000 per day. The city can also order removal of non-compliant structures.
