The Louisiana Trustee Implementation Group is seeking public input on a draft restoration plan proposing an investment of up to $2 billion in the Mid-Barataria Sediment Diversion project. If approved, the large-scale project would reconnect the Mississippi River to Louisiana’s Barataria Basin. The project will allow the controlled release of freshwater, nutrients and sediment back into the basin to rebuild wetlands and contribute to the broader restoration of its ecosystem.

The Draft Phase II Restoration Plan #3.2 is available for public comment for 60 days through May 4, 2021, with virtual public meetings to present the draft plan and draft environmental impact statement April 6, 7, and 8, 2021. The draft plan evaluates six design alternatives for the diversion project and identifies one of them as preferred.

NOAA and the Coastal Protection and Restoration Authority (CPRA) are lead Trustees for the draft plan, which was prepared jointly with the other Louisiana Restoration Area Trustees.

Concurrent with release of the draft restoration plan, the U.S. Army Corps of Engineers is releasing a draft environmental impact statement, also available for public comment for 60 days. The environmental impact statement and information on how to submit comments are on the Army Corps’ website.

Reducing Land Loss Exacerbated by the Deepwater Horizon Oil Spill

Louisiana and the Barataria Basin are in the midst of a land loss crisis. The Basin has lost more than 276,000 acres of land since the 1930s. Wetlands in the Basin were the most heavily impacted by the Deepwater Horizon oil spill, which accelerated a severe land loss trend threatening Louisiana’s estuaries. The oil spill and response activities significantly accelerated the rate of wetland loss in the area.

The project would restore and sustain a significant amount of wetland habitat—tens of thousands of acres—and the resources that depend on them, over the next several decades. At peak capacity, the proposed preferred alternative would transport up to 75,000 cubic feet per second of freshwater and its sediment and nutrients—harnessing nature through engineering to re-establish the natural process that originally built Louisiana’s coastal wetlands.

Draft Restoration Plan Comment Period and Virtual Public Meetings

Public comments will be accepted for 60 days through May 4. We encourage you to review and comment on the draft plan by submitting comments online, by mail, or during virtual public meetings listed below.

Virtual Community Conversations with Environmental Law Institute and the Restore the Mississippi River Delta

The Louisiana Trustee Implementation Group, CPRA, and the Environmental Law Institute have partnered to host a dialogue—facilitated by the Restore the Mississippi River Delta—to provide information on the Mid-Barataria Sediment Diversion.

These virtual meetings will provide the public with an informal opportunity to learn and ask questions about the project and the permitting process. CPRA and Louisiana Trustee Implementation Group members will guide participants through the recently released draft environmental statement and draft restoration plan.  We will also discuss how participants can participate in the upcoming formal public meetings and submit formal public comments.

These meetings are not an opportunity to comment formally on the draft restoration plan and draft environmental impact statement, like the meetings scheduled for April 6 – 8. These virtual community conversations are a chance to better understand the two documents and the Mid-Barataria Sediment Diversion project through a dialogue with the participating organizations.

Additional Background Information and Documents

Recognizing the loss of marsh productivity caused by the Deepwater Horizon oil spill and the importance of Louisiana’s marshes to the Gulf of Mexico ecosystem, the historic 2016 Natural Resource Damages settlement allocated almost half of the funding, $4 billion, to restoring Louisiana’s coastal and nearshore habitats.

In 2017, the Louisiana Trustee Implementation Group released a draft and in 2018 approved a final strategic restoration plan prioritizing large-scale sediment diversion, marsh creation, and ridge restoration techniques and approaches for the Barataria Basin. The strategic plan included the Mid-Barataria Sediment Diversion and other projects for evaluation and planning.
