Chattanooga, Tennessee property owners and developers must follow local floodplain rules when planning construction or land changes in identified flood zones.

Overview of Floodplain Rules

The City of Chattanooga enforces floodplain management to reduce risk to life and property, align with the National Flood Insurance Program, and regulate construction, fill, and substantial improvements in mapped flood hazard areas. Rules cover elevation requirements, lowest floor standards, and conditions for development in Special Flood Hazard Areas (SFHAs). The planning and development division and stormwater management coordinate reviews for permits and compliance.

Check the city maps early in project planning to avoid delays.
