The Pass Chaland to Grand Bayou Pass Barrier Shoreline Project is located along the Bay Joe Wise Headland between the confluence of Bayou Huertes with the Gulf shoreline to Grand Bayou Pass in Plaquemines Parish, Barataria Basin, Louisiana. Wetland, dune and marsh habitats within the project area have undergone substantial loss due to oil and gas activities, subsidence, sea level rise, and storm erosion.

Development of fragmentary islands from breaches in the barrier headland and subsequent inlet formations have resulted from increased tidal prism storage and storm related impacts.

CEC is part of an integrated consulting team providing comprehensive services for implementation of the Project (BA-35, CWPPRA Priority Project List 11) by the National Martine Fisheries Service and the Louisiana Department of Natural Resources.

The Project is funded and authorized in accordance with the provisions of the Coastal Wetlands Planning, Protection, and Restoration Act (16 U.S.C.A., Sections 3951-3956) and has been approved by the PL 101-646 Task Force.

The Project objective is to protect and preserve the structural integrity of the barrier shoreline. The Project includes construction of a 1,000 feet wide marsh platform using 2.5 million cubic yards of dredged material, and a beach and dune component to address the severity of erosion along the gulf-front shoreline using 800,000 cubic yards of dredged material. The marsh and dune will be planted with appropriate vegetation. The Project area anticipated to benefit by the marsh, beach and dune creation is 359 acres, which will protect/create approximately 161 acres of barrier island habitat at year 20 of the design life.

The scope of services includes engineering and design, evaluating the site conditions of the proposed borrow areas and fill sites, analyzing potential adverse effects of utilizing the borrow sites, maintaining safe navigation and flushing through the passes on each end of the headland without stabilization, identifying potential conflicts with oyster leases and oil and gas activities, documenting construction access, modeling circulation and flushing through the estuary to preserve water quality in the bay and tributaries, evaluating the economic and technical feasibility of the conceptual project, preparing detailed plans and specifications, providing permit technical assistance, and developing monitoring plans.
