AUTHORIZATION: Section 22 of the 1974 Water Resources and Development Act (WRDA), Planning Assistance to States (PAS).

TYPE OF PROJECT: Flood Risk Management

LOCATION: Nashville, TN

CONGRESSIONAL INTEREST:  Cooper (TN-05), Hagerty (TN), Blackburn (TN)

NON-FEDERAL SPONSOR: City of Nashville, TN

 

BACKGROUND:  The City of Nashville has experienced repeated flooding in the last decade, including a large flood in March 2021.  This flood preparedness initiative is a joint effort with Metro Nashville Water Services, Planning Commission, Office of Emergency Management, Corps, U.S. Geological Survey, and National Weather Service.  The city and Corps are partnering to develop tools for a comprehensive flood warning and response plan in Davidson County.  This includes county wide updates to stream models and inundation mapping for a range of potential flood events, and updates to flood insurance studies. This information allows emergency responders to react to critical areas of the county during natural disaster events.  The models are being shared with FEMA for inclusion in the Flood Insurance Map update for Davidson County.

 

IMPORTANCE: Updating the FIS will help better define floodplains and reduce future flood risk. Providing better tools for decision makers and emergency responders will also reduce flood risk.
