Bayou Dupont Sediment Delivery System

PROJECT LOCATION:

The project is located adjacent to Bayou Dupont and southeast of Cheniere Traverse Bayou in the vicinity of Ironton in Plaquemines Parish and Lafitte in Jefferson Parish, Louisiana. The general area lies west of Louisiana Highway 23 and just north of the Myrtle Grove Marina within the Barataria Basin.

PROJECT DESCRIPTION:

This project will create/restore approximately 538 acres of brackish marsh by delivering sediments dredged from the Mississippi River via pipeline, and planting marsh vegetation. The project would dredge sediment for marsh creation from the Mississippi River, and deliver it to an adjacent area within the Barataria Basin. Project area marshes have degraded to almost entirely open water due to a combination of causes including lack of natural freshwater and sediment input, subsidence, and the dredging of oil and gas canals. The proximity to the Mississippi River is an excellent opportunity to design a sediment delivery system that will utilize sediment from the river to restore and create wetlands in this area of critical need. Unlike most marsh creation projects, this project will not borrow material from existing shallow bay bottoms, which may have implications for surrounding sediment dynamics and water quality at the borrow area. Ideally, this sediment would be transported into areas of need using freshwater/sediment diversions.

PROJECT STATUS: (Project Status Last Updated: 21-Jan-2013 )

Additional post-primary construction activities will not be pursued. Sponsors will be proceeding with construction grant close-out activities.

FUND STATUS:

The current project estimate is $27,231,106 , which includes $26,716,592 for construction first costs, and $403,701 and $110,813 for 20 years of monitoring and operations and maintenance, respectively.
