To fix seepage of the Mississippi River through the existing levee and avoid potential flood control system failure.
The U.S. Army Corp of Engineers’ original scope consisted of 15,200 SF of sheet pile driven through the crown of the Mississippi River levee including jet grouting under two existing siphon pipes. APC proposed a value-engineering option to USACE to remove/reinstall the siphons pipes and install sheet piles for the entire length of the project, thus eliminating the need and more importantly, the additional cost for jet grout.
Our value-engineering proposal increased the quantity of sheet piles to 22,800 SF while removing all jet grouting. A compacted levee embankment was installed by APC to raise the levee to the current levee elevation standards. All this work was safely performed while maintaining access to residences and a marine terminal business on the unprotected side of the levee. Once the embankment was completed, an asphalt walking path was installed on the levee allowing residents to enjoy the scenic Mississippi River.
