Beneficial Use of Dredged Sediment in Cameron Parish

The Louisiana Coastal Protection and Restoration Authority (CPRA) has announced that construction is complete on the Oyster Bayou Marsh Creation and Terracing project in Cameron Parish.

Located west of the Calcasieu Ship Channel near the Gulf of Mexico, this project used dredged sediment from the Gulf of Mexico to create and nourish approximately 600 acres of salt marsh and more than 2.5 miles of earthen terraces.

The work that has been completed here will work hand in hand with other restoration projects we’ve done in the area and demonstrates our commitment to southwest Louisiana,” said CPRA Board Chair Chip Kline. “Improving and protecting the ecosystems along Louisiana’s coast is vitally important to our state’s future.”

Prior to restoration, the project area had experienced altered hydrology, drought stress, saltwater intrusion and hurricane-induced damage that caused it to lose much of its valuable wetlands.

The newly created and nourished marsh will reduce the rate of wetland loss, and the earthen terraces will further reduce erosion north of the marsh area.

This CWPRRA project with at a cost of $31 million was designed to work synergistically with an earlier completed project, the Cameron Shoreline Restoration project. Completed in 2014, this project restored nine miles of shoreline from the Calcasieu Ship Channel’s entrance to beyond Holly Beach.

When you put 600 acres of new marsh between citizens of southwest Louisiana and the Gulf of Mexico along with 2.5 miles of earthen terraces it employs our multiple lines of defense strategies in terms of protection and restoration,” said Laurie Cormier, Calcasieu Parish coastal zone administrator and CPRA Board Member.

Another project nearing completion in the region is the Cameron-Creole Watershed Grand Bayou Marsh Creation project, located about six miles northeast of the community of Cameron.

This project benefits 534 acres of marsh. This was a CWPRRA funded project at a cost of $24.7 million. In January 2019, an additional $2.3 million was allocated from the Department of Natural Resources (DNR) mitigation and beneficial use funds, which could expand the project to an additional 50 or more acres of marsh restoration and nourishment.
