There are a number of reasons for this severe and detrimental loss of land, including: sea level rise, subsidence, saltwater intrusion, manmade contributions, the Deepwater Horizon oil spill and subsequent response activities, and side effects of our current levee system. Our levees, which provide critically important flood protection to our coastal communities, have cut off the Mississippi River from Barataria Basin, restricting it from depositing sediment and nutrients into the basin.
Since the 1930’s, Barataria Basin has lost more than 276,000 acres of land.
If we do nothing to address our land loss crisis, Barataria Basin is expected to lose an additional 274,000 acres of land over the next 50 years. The estuary will collapse, and the communities, industry, wildlife, and fisheries that rely on the basin will no longer be able to do so.
The Louisiana Coastal Protection and Restoration Authority has determined, as part of its Coastal Master Plan, that sediment diversions are the state’s best chance at restoring, building, and sustaining wetlands and retaining a functional ecosystem that will preserve the communities, culture, species, and industries that rely on it.
Sediment diversions are designed to re-establish the natural processes that originally created the delta and restore and maintain wetlands lost over the past century – something other projects, like dredging and barrier island creation, cannot fully do.
We need an integrated approach to coastal protection and restoration, using all the tools in the toolbox to rebuild and sustain land.
The Mid-Barataria Sediment Diversion is one of the largest and most innovative coastal restoration efforts ever undertaken and one of the largest environmental infrastructure projects in the history of the United States.
