CHALMETTE LEVEE LOOP, BAYOU BIENVENUE TO BAYOU DUPRE, REACH LPV-145

New Orleans, Louisiana

The U.S. Army Corps of Engineers, as part of the overall extensive New Orleans hurricane flood protection program, raised the levees on the west side of the MRGO channel and Lake Borgne in St. Bernard Parish. The existing levee from Bayou Bienvenue to Cavernarnon is approximately 15 miles long and was severely damaged by Hurricane Katrina. The LPV 145 Project is the northernmost segment of the T-wall project, approximately 30,300 feet long. The pile-supported concrete T-wall extended the levee protection up to Elevation (+) 30 feet MSL from an existing levee embankment of (+) 18 feet MSL. As part of a joint venture, Massman was awarded this contract by the Corps under an ECI Incentive contract, an alternative contracting method for special projects. The project's critical location made this work a priority for the Corps to include in the hurricane protection measures to be completed by June 2011, prior to the hurricane season. The design of this T-wall section was only 20% complete during the proposal period.
