About this file
This file is a presentation deck for the 2025 Mississippi Valley Division (MVD) Industry Day, focusing on the Mississippi River and Tributaries (MR&T) Project. The presentation highlights critical infrastructure investments, flood control efforts, and upcoming contract opportunities across multiple U.S. Army Corps of Engineers districts in seven states. Key project areas include Mississippi River Channel Improvement (with 341 miles of dikes and 1,058 miles of revetment), Mississippi River Levee System reconstruction, Atchafalaya Basin development, and the Morganza to the Gulf hurricane protection project.
The document outlines significant investment and impact statistics, including $21.5 billion invested since 1928, preventing $2.45 trillion in flood damages, with a 114:1 return on investment. Upcoming contract opportunities are detailed, with Atchafalaya Basin projects ranging from $0-$20 million and Morganza to the Gulf contracts ranging from $30-$100 million, with multiple features under design and construction. The presentation covers projects involving levee enlargements, seepage berms, sheet pile installations, and flood risk management across Mississippi River districts, positioning potential contractors for future federal infrastructure work.

6MISSISSIPPI RIVER LEVEES
The Mainline Mississippi
River Levee System (MRL) extends from Cape
Girardeau, MO to Head of
Passes, LA and is approximately 1,610 miles in length.
The MRL lies within the
Memphis, Vicksburg, and New Orleans Districts.
Segments of the MRL in all
3 Districts are below the authorized grade and/or require other work such as seepage remediation or slope flattening.
MISSISSIPPI RIVER LEVEE CONSTRUCTION
• Levee Enlargements
• Seepage Berms
• Sheet Pile
• Relief Wells

ATCHAFALAYA BASIN OVERVIEW
• The Atchafalaya Basin is the largest existing wetland in the
United States encompassing 1.4 mil acres of land.
• The Atchafalaya Basin consists of 450 total miles of levees and floodwalls.
• The System is designed to carry one half of the 3,000,000 CFS project flood at the latitude of Old River, Louisiana.
• Tentative projects for award consist of levee lifts/enlargements
• There are eight (8) contracts:
o Seven (7) features under design o One (1) currently in construction
• Two (2) contracts tentatively upcoming for award before 2027
• Project awards range in magnitude from $0 to $20M
MORGANZA TO THE GULF
• Morganza to the Gulf (MTG) is designed to reduce the risk of damage related to storm surge to approximately 52,000 structures and a population of over 200,000 in an area of intense concentration of energy infrastructure near the confluence of two nationally significant navigation corridors in the Mississippi River and the Gulf Intracoastal Waterway (GIWW).
• The project is designed to provide a 100-year level of risk reduction (LORR) hurricane and storm risk reduction project in
Terrebonne and Lafourche Parishes, Louisiana, while ensuring navigational passage and tidal exchange.
• MTG consists of 98 total miles of levees and structures.
• Tentative projects for award include Structures
(floodgates, control structures, floodwalls), levees, wetland creation, and compensatory mitigation credit procurement.
