Marsh Creation

New Orleans East Land-Bridge Restoration

  • Project TypeMarsh Creation
  • Project BasinPontchartrain-Maurepas Basin
  • ParishOrleans, St. Tammany

This project consists of marsh creation via the Sediment Conveyance Pipeline East project and is located in east New Orleans on a narrow landbridge separating Lake Pontchartrain from Lake Borgne, where local subsidence and canals have raised salinities. This, combined with the exposure to high wave energy, has resulted in rapid retreat of the shoreline and the expansion of ponds and lakes within the marsh. This project will create and restore marsh via a sediment conveyance pipeline. Restoration of the project area is a critical landscape feature. It separates Lake Pontchartrain from the Gulf, providing an estuarine habitat. It also is a crucial line of defense from storm surge for more than 1.5 million people in eight parishes, including the cities of New Orleans, Laplace, Madisonville, Mandeville and Slidell.
