FEMA flood zone rules in Baton Rouge, LA — also called floodplain regulations or special flood hazard area (SFHA) rules — determine flood insurance requirements and elevation standards for new construction.
Baton Rouge has extensive FEMA-designated flood zones throughout East Baton Rouge Parish. The 2016 Great Flood devastated the area. Flood insurance is critical, and new construction must meet strict floodplain management standards.
Baton Rouge and East Baton Rouge Parish have extensive FEMA-designated flood hazard areas along the Amite River, Comite River, Bayou Manchac, and numerous other waterways. The August 2016 Great Flood caused catastrophic damage across the region, highlighting the city-parish's significant flood vulnerability. FEMA Flood Insurance Rate Maps designate Special Flood Hazard Areas where flood insurance is mandatory for federally backed mortgages. The city-parish stormwater management ordinances require new construction to elevate above Base Flood Elevation. The East Baton Rouge Stormwater Master Plan guides flood mitigation efforts. The city-parish participates in the National Flood Insurance Program and Community Rating System.
Construction in flood zones without proper permits and elevation certificates violates local and federal regulations. Non-compliance may affect NFIP coverage.
