The 4,420-acre Golden Triangle Marsh project proposed in the 2017 Coastal Master Plan provides a vital wetland buffer along urban areas of New Orleans. The area has has been significantly impacted by human intervention. Dominated by brackish marsh, this area was badly damaged by saltwater intrusion and erosion following the dredging of the now-closed Mississippi River Gulf Outlet (MRGO).

This 700-acre Golden Triangle Marsh creation project (PO-0163) is located near the confluence of two major navigation and shipping channels — the MRGO and the Gulf Intracoastal Waterway. This project used sediment from nearby Lake Borgne to create and restore marsh. Restoration of this area is critical as it provides flood protection and enhances community resilience for the Greater New Orleans area, while also provides estuarine habitat for fish and wildlife in Lake Borgne and the Mississippi Sound.

Construction of the Golden Triangle Marsh Creation project began in 2021 and is now complete.
