All Lafourche Parish's protective barrier islands--Timbalier Island, Isles Dernieres and Grand Isle-- sustained severe erosion and land loss in the 2005 hurricane season. Coastal barrier dunes, marsh and beaches are the parish's first line of defense, helping reduce storm surge and flood damage to Port Fourchon, the South Lafourche economic corridor, and the Lafourche Parish ring levee system. Hurricane Katrina over-wash eroded and caused significant land loss on eastern Timbalier. Risk of tidal flooding increases as these critical barriers shrink and become less effective at reducing wave energy.
Expedite restoration of Timbalier Island, Isle Derniers, and Grand Isle to restore coastal barrier islands that reduce tidal flooding in south Lafourche Parish. Establish a series of approximately 15 miles of slurry pipelines with pumps and outlet units for slurry distribution will be used to restore 5 square miles of barrier islands (estimated hurricane loss on these three islands). Pipeline locations would be established to harvest sediment from the "Ship Shoal" location in the Gulf of Mexico (this is an existing sediment source). Sediment materials will be transported via pipeline slurry to barrier island locations where land loss has occurred. This project will establish a permanent system of barrier island restoration that will help to maintain these islands.
This project has a community wide impact because it provides the first line of defense for critical National infrastructure such as Port Fourchon, which is the inter-modal hub of Louisiana's offshore energy industry, as well as the economic engine of Lafourche Parish.
