Corps awards contract for removal of Interim Closure Structures

NEW ORLEANS – The U.S. Army Corps of Engineers, New Orleans District awarded a $17 million contract to St. Rose, LA, based small business M.R. Pittman Group, LLC for removal of the Interim Closure Structures (ICS) at three outfall canals along the New Orleans lakefront.  

The 17th Street, London and Orleans avenues outfall canals ICS will be demolished with all associated above ground equipment, machinery, buildings and platforms removed.  The work also includes removal of exposed sheet piling, partial removal and replacement of scour protection, concrete capping of I-Walls, placement of riprap, aesthetic improvements and other incidental work.

Work is scheduled to begin in December 2018 and be completed in summer 2020.  For additional information or questions, please call the Army Corps Construction Hotline at (877) 427-0345.

The ICS were constructed in 2006 to temporarily provide 100-year level of risk reduction while the Permanent Canal Closures and Pumps (PCCP) were designed and built.  The ICS performed as designed by preventing surge from Lake Pontchartrain from entering the outfall canals during six named-storm events, including Hurricanes Gustav, Ike, Isaac and Nate.

The PCCP have since replaced the ICS and provide a permanent and sustainable means for defending against a 100-year storm surge event, or an event that has a 1-percent chance of occurring in any given year.  Construction of the PCCP began in May of 2013 and was completed in May of 2018.  Operation and maintenance of the structures is now undertaken by the Southeast Louisiana Flood Protection Authority-East.
