Island Road Marsh Creation and Nourishment Project in Terrebonne Parish

under planning

The Louisiana Coastal Protection and Restoration Authority is planning to carry out the Island Road Marsh Creation and Nourishment Project in Terrebonne Parish. The project involves restoring marsh adjacent to the Twin Pipelines and parallel to Isle de Jean Charles. The work includes rebuilding the structural framework of degraded marsh near the Twin Pipelines and restoring resilient habitat by marsh creation and nourishment, which will create 229 acres of marsh, nourish 66 acres of existing marsh and result in approximately 206 net marsh acres after 20 years. Sediment would be mined from Lake Tambour and pumped into three confined disposal cells. Dikes would be gapped prior to demobilization for dewatering and additionally, no later than three years after construction, for tidal function. The project is valued at $40.4 million.
