The Challenge

To Be Met

The Mid-Barataria Sediment Diversion Project (BA-153) has been identified as a large-scale, long-term restoration project recommended for implementation in Louisiana’s Comprehensive Master Plan for a Sustainable Coast. The Project is the largest proposed sediment diversion that will reconnect the Mississippi River to the Barataria Basin. Sediments and freshwater will be transported into the nutrient starved basin while maintaining the current level of flood protection to the area. The Project is proposed to have a design flow capacity of 75,000 cfs while maximizing the Sediment to Water Ration (SWR). The goal of the project is to reestablish deltaic processes in order to build, sustain, and maintain land.

The Solution

Our Creative Approach

As a major subconsultant, TBS is providing engineering and design services for the beneficial use of excess material from the Project. The project will utilize an alternative delivery method known as Construction Management at Risk (CMAR). The Design Team will work with the CMAR contractor to incorporate constructability into the design of the Project. TBS is also providing the following: magnetometer surveys; Mississippi River sediment monitoring surveys; Mississippi River levee tie-in floodwalls; NOV Levee tie-in; LA 23 floodwalls; wing wall design (intake); outfall channel design; utility relocation coordination; beneficial use of excavated materials; and the MBSD monitoring plan.
