Background: The MTG hurricane and storm damage risk reduction project is a levee system located approximately 60 miles southwest of New Orleans, Louisiana and includes most of Terrebonne Parish and a portion of Lafourche Parish between the Terrebonne Parish eastern boundary and Bayou Lafourche. The purpose of this project is to reduce the risk of damage caused by hurricane storm surges.

A review of the project is needed because of the increasing susceptibility of coastal communities to storm surge due to wetland loss, sea level rise, and subsidence. The MTG Project was initially authorized by Section 1001(24) of the Water Resources Development Act (WRDA) of 2007 in accordance with the Reports of the Chief of Engineers dated 23 August 2002 and 22 July 2003, at a total cost of $886.7 million.

The project was redesigned in the 2013 Integrated Revised Programmatic EIS (RPEIS) and Post Authorization Change Report, both to address the project cost increase beyond the statutory limitation in accordance with Section 902 of the WRDA of 1986, as amended, and to meet updated post-Hurricane Katrina design guidelines. The MTG Project was subsequently re-authorized by Section 7002(3)5 of the Water Resources Reform and Development Act of 2014 in accordance with the Report of the Chief of Engineers dated 8 July 2013, at an updated total cost of $10,265,100,000.

The MTG project was authorized to provide the 1% AEP level of hurricane and storm damage risk reduction while maintaining navigational passage and tidal exchange. The project consists of approximately 98 miles of levee including associated navigation, roadway, pump station fronting protection, and environmental control structures. The 2013 RPEIS provided an assessment for both programmatic and constructible features for the MTG project. Constructible features consisted of those project features that were determined to have sufficient design details to be constructed. Constructible features included levee reaches F1, F2, G1; the HNC Lock; and the Bayou Grand Caillou Floodgate. The remaining features were designed to a programmatic design level that would require supplemental National Environmental Policy Act documentation prior to construction. The mitigation plan for the constructible features included restoration of 427 acres of intermediate marsh, 358 acres of brackish marsh and 975 acres of saline marsh.

This SEIS will disclose the context and intensity of environmental impacts, including indirect and cumulative effects, for the final array of levee alignments and associated features. Any required mitigation will also be discussed.

The public scoping period is extended until August 26, 2024. Comments must be submitted by this date to ensure they are considered in the planning of the project and captured in the Scoping Report.
