Title: American River Watershed Common Features Mayhew Levee Project
Description: The project would involve reconstructing the entire 4,300 feet of levee to meet current Corps engineering standards. The work would include excavating portions of the old levee and then realigning, recontouring, and raising the levee by adding and compacting fill material. During construction, a 50- to 60-foot deep by 2-foot-wide slurry wall would be installed beneath the new levee to prevent piping of foundation materials that could trigger a failure of the structure. The new levee would be an average of 8 feet high and have a 2H:1V landside slope and 3H:1V waterside slope. The levee crown would be 20 feet wide and covered in aggregate base material.
