The United States Army Corps of Engineers (USACE) Sacramento District (SPK) anticipates a potential requirement for design-bid-build (DBB) construction services to conduct erosion control and levee strengthening protections along the South bank of the Lower American River (LAR) in Sacramento, California (CA). The anticipated project is required to continue American River Common Features (ARCF) erosion reduction efforts along the LAR. Prior efforts were awarded under USACE contract W9123824C0014, LAR Contract 3 (C3) A. The anticipated forthcoming requirement is referred to as “LAR C3B” (Contract 3B). The Government anticipates work will be required along the South bank of the American River (Site 4-1) to include constructing launchable rock toe, launchable trench, bank protection, and tie backs along approximately 1.5 miles of river, located on the left (South) bank, which roughly extends from Watt Avenue upstream to near Mayhew Drain. The Government anticipates work will include excavating, placement, and regrading of material on the riverbank slope and levee embankment, installation of soil-filled rock slope protection on the waterside levee face and riverbank, soil and rock placement to construct river toe protection and planting bench features, instream wood structure placement on the planting benches, construction of buried launchable trench features in the overbank, tie-in of erosion protection elements to existing rock revetment features, providing temporary erosion control for stabilization of disturbed soil areas, and import and placement of riprap. The Government anticipates vegetation clearing will be performed under a separate Government contract prior to erosion protection efforts. The Government anticipates the requirement will be fully designed.
