The Lake Borgne Marsh Creation (LBMC) Project Increment One is one of six projects selected through the Natural Resources Damage Assessment (NRDA) process to mitigate impacts as a result of with the Deepwater Horizon Oil Spill. As outlined in the Final Restoration Plan dated January 2017 prepared by the Louisiana Trustee Implementation Group (TIG), the Plan focuses on the implementation of the large-scale marsh creation projects due to the immediate benefits to coastal habitats directly impacted by the oil spill. This specific project is anticipated to create approximately 3,700 acres of marsh with an anticipated construction budget of $62M. When completed, the project will represent one of the largest marsh creation projects to be implemented by the Coastal Protection and Restoration Authority (CPRA) to date. Borrow material for the marsh creation is procured from Lake Borgne; however, an evaluation of borrow material from the Mississippi River, as well as Mobile (Alabama) Sands were considered in the design of the project. The marsh creation area will extend from the eastern shore of the Bayou Yscloskey approximately 4.3 miles to the east toward Lena Lagoon.

As the lead engineer & project manager, DDG has coordinated all data collection activities including topographic, bathymetric, magnetometer, and side-scan survey; geotechnical data collection, and environmental data collection analysis to define the marsh creation borrow and fill areas, prepare detailed designs and cost estimates, obtained all required regulatory permits, and supported bidding services. DDG is currently performing construction administration and full-time inspection services on behalf of CPRA. The project is expected to be completed in Q4 2025.
