East Timbalier Island Restoration Project
East Timbalier Island Restoration Project
East Timbalier is a 400-acre island in LaFourche Parish, Louisiana and is part of an island chain that fronts Terrebonne/Timbalier Bay. Construction on East Timbalier was completed in December 1999 and involved the creation of emergent habitat to increase the longevity of the island using soft-structural techniques (sand placement) and hard structures (rubble mound revetment) where shoreline stabilization was needed. Almost three million cubic yards of sediment were utilized to establish a 200-foot wide dune and a 600-foot wide marsh along the length of the island. This created 170 acres of intertidal marsh and is helping to protect thousands of acres of existing fringing marsh to the north. To further stabilize the dredged sediments, 13,000 feet of sand fences and approximately 20,000 plugs of marsh grasses were added in May 2000 and June 2001 respectively.
