Review Plan for Engineering and Design Products for the Gallatin, Tennessee Flood Risk Reduction Project

The purpose of this project is to reduce flood damages in the East Camp Creek Watershed. A feasibility report was approved in March 2019 and the Entrance Detention project was the recommended plan. The project is a detention structure located at Triple Creek Park owned by the City of Gallatin. The Entrance Detention project is a 780-foot earthen storage structure with an average height of 4 feet and heights up to 10 feet. The width of the structure would be 10 feet at the top of the structure. The entire structure would be armored with stone protection to prevent erosion and ensure structural integrity during overtopping events. The upstream and downstream sides of the structure are designed to be constructed at 2H:1V slope to ensure structural slope stability and accommodate the placement and retention of sufficient armor stone. The structure is designed with a culvert placed in the channel of the existing stream.
