BACKGROUND: Due to excessive rain events during the winter of 2016/2017 Sacramento area levees experienced varying forms of erosion. The construction work for this site is remedial in nature, which involves rehabilitating the existing levee that experienced flood damage. In order to construct the adjacent levee, dewatering of the ditch at the landside levee toe may be required. The entire site will initially be cleared, grubbed and stripped of organics, vegetation and all loose, wet or deleterious material. The landside slope will be excavated to facilitate placement of fill on the landside slope and a landside berm. A keyway will be excavated below the location of the new levee toe. Upon completion, the slope will be seeded and the levee crown and toe road will be surfaced with aggregate base.
