Project Description

The project will create or restore approximately 774 acres of broken marsh and open water, which comprises the restoration of 694 acres of degraded marsh and nourishment of 80 acres of marsh, through the construction of approximately 44,000 linear feet of containment dikes. This marsh restoration will provide 494 acres of intertidal habitat and 263 acres of subtidal habitat. The project will help buffer the surge barrier, which would increase flood protections to highly populated areas of New Orleans and provide important estuarine habitat for Lake Borgne. The Golden Triangle Marsh Creation project is in the eastern portion of the Golden Triangle Marsh and is adjacent to New Orleans, Louisiana, and the surrounding communities in Orleans Parish and St. Bernard Parish. The Golden Triangle Marsh, which is a narrow band of brackish marsh, is directly east of New Orleans between Lake Borgne and the confluence of the Mississippi River Gulf Outlet (MRGO) and the Gulf Intracoastal Waterway (GIWW). The northern portion of the marsh falls within the Bayou Sauvage National Wildlife Refuge (NWR), which is one of the last remaining marsh areas adjacent to Lakes Pontchartrain and Borgne. This project was funded for Engineering and Design through the RESTORE Act (Resources and Ecosystems Sustainability, Tourist Opportunities, and Revived Economies of the Gulf Coast States Act) and was then selected for implementation with Natural Resources Damage Assessment (NRDA) funds in the Louisiana Trustee Implementation Group (LA TIG) Final Restoration Plan/Environmental Assessment #6 in April 2020.
