The Barataria Basin Barrier Shoreline is the regional segment of the Gulf Coast of the Louisiana that is situated between the west bank of the Mississippi River at the active delta and the eastern shore of Terrebonne Bay. The project consists of two reaches. The Caminada Headland is located at the southern end of Lafourche and Jefferson Parishes. Shell Island is part of the Plaquemines Parish barrier island chain.

The purpose of the proposed action is to restore the geomorphic (physical) function of the barrier island. Restoration of the shoreline and coastal marshes of Caminada Headland and Shell Island would restore critical habitat, form and function, and long-term sustainability of the barrier shoreline.

Shoreline restoration and protection at Caminada Headland and Shell Island is needed to stabilize the geomorphic features and reduce the rapid rate of shoreline loss. Materials will be pumped from offshore (Caminada) and riverine (Shell Island) sources to restore the dune, shoreline, and interior marsh habitats. The restoration of the shoreline and marsh will protect the interior marsh and chenier ridge habitats for essential fish and wildlife species by providing a buffer from the marine influences of the Gulf of Mexico.
