Developing Louisiana’s Mid-Barataria Sediment Diversion


  • Louisiana needs to reinforce its coasts and shores; the Mid-Barataria Sediment Diversion was proposed.
  • Abt is helping to develop the restoration plan and reviewing impacts, including environmental justice impacts.
  • The project is open for public comment.
The Challenge

Louisiana needs to rebuild its eroding coastline, which is degrading in part because levees prevent sediment from the Mississippi River from replenishing coastal areas. The Mid-Barataria Sediment Diversion (MBSD) was proposed to reconnect the river to coastal wetlands, which will improve their productivity and sustainability over the next few decades. The Louisiana Coastal Protection and Restoration Authority and the Louisiana Trustee Implementation Group hired Abt to support the development of an MBSD Draft Restoration Plan, including supporting associated environmental impact studies. 

The Approach

Abt is working closely with Trustees, providing support that includes:

  • Preparing a draft restoration plan that describes and explains the Trustees’ recommendation to fund and implement the MBSD. 
  • Preparing a technical report evaluating the socioeconomic impacts of the MBSD for inclusion in the project’s Environmental Impact Statement (EIS).
  • Preparing a report evaluating the MBSD’s impact on low income and minority communities.
  • Providing technical review and comment on various aspects of the project’s EIS, which is being prepared by a third-party contractor.
The Results

The Draft Restoration Plan is currently available for public review and comment.
