FEMA flood zone rules in Huntsville, AL β also called floodplain regulations or special flood hazard area (SFHA) rules β determine flood insurance requirements and elevation standards for new construction.
Huntsville participates in the National Flood Insurance Program (NFIP) with Community Rating System (CRS) participation providing flood insurance discounts. Tennessee River, Flint River, and Aldridge Creek flood zones require elevation certificates.
Huntsville Code Chapter 16 (Flood Damage Prevention) adopts FEMA FIRM maps. New construction in Special Flood Hazard Areas (SFHA) must elevate lowest floor 1 foot above base flood elevation (freeboard). Substantial improvement (50% rule) triggers full compliance. Elevation certificates required before CO issuance.
Unpermitted SFHA construction: $500-$5,000 fine plus required removal/elevation. NFIP policy denial risk.
