A federal portal where the public can look up flood hazard maps for an address or area.
The Federal Emergency Management Agency, known as FEMA, hosts the Flood Map Service Center, a portal where users can search an address and view flood hazard maps. Walls near creeks, low areas and drainage ways may be affected by floodplains and flood rules. Owners in Nashville can check the maps to understand whether their property or a wall site lies in a mapped flood hazard area.
We are a private company and are not part of FEMA. Floodplain rules can limit what may be built, and local officials interpret them, so we encourage owners to talk with city staff when a project is near a creek or low area. We use flood information to plan drainage, wall type and materials, and to decide when extra permits or engineering are likely. The official portal is straightforward to use.
