St. Tammany Parish Draft Feasibility Report available for review

Published June 11, 2021

The U.S. Army Corps of Engineers, New Orleans District released its St. Tammany Parish Feasibility Study Draft Report with Integrated Environmental Impact Statement for a 45-day public review and comment period.

The Tentatively Selected Plan (TSP) identified in the draft report consists of approximately 14 miles of levees and 2 miles of floodwall in Slidell, clearing and snagging of Bayou Patassat, channel improvements in Mile Branch, and elevations and floodproofing for approximately 8,500 structures located in the 50-year flood plain.

The goal of the St. Tammany Parish Study is to develop alternatives to reduce flood damages caused by hurricane and rainfall events. The study is funded by the Bipartisan Budget Act of 2018 and was initiated in January 2020 following execution of the Feasibility Cost Share agreement with the Coastal Protection and Restoration Authority Board.

The general public, interested parties, and stakeholders are invited to comment on the TSP. The draft report contains a description of the project, an evaluation of the alternatives under consideration, and an analysis of potential environmental impacts. All public comments received will be addressed and considered accordingly as part of the continued development of the TSP into a more detailed recommended plan.

Due to COVID-19, USACE will host virtual public meetings to provide information on the TSP and to receive public comments; times and meeting details will follow in a subsequent media release and advertisements. Information about public meetings, including login information, will be posted to the New Orleans District website:

The New Orleans District will accept written comments on the TSP for a 45-day period starting June 11, 2021 through July 26, 2021. All comments received during the public review period will be considered as part of the decision-making process.
