USACE SPK DBB Construction - Lower American River, Site 2-1

The U.S. Army Corps of Engineers (USACE), Sacramento District (SPK), anticipates a potential requirement to repair erosion at Site 2-1 located on the American River in Sacramento, California. Work is anticipated to include design-bid-build (DBB) construction services to provide roughly 5,500 feet of stream bank protection and stabilization of the existing levee, to protect critical infrastructure against the effects of erosion during large flood events. Most vegetation will be cleared from the project footprint prior to construction; however, the Contractor will be required to clear remaining vegetation and stumps, grub, and strip the project footprint, place soil and rock revetment on the waterside levee face and riverbank, place soil and erosion control netting to construct planting benches, place instream wood structures on the planting benches, and plant and seed the placed material. About 4,100 feet of the site will require working in the active channel of the American River to place material. The project will require import and placement of approximately 143,000 tons of rock riprap, approximately 38,000 tons of bedding material, approximately 31,000 cubic yard of top soil, approximately 180 trees, and approximately 855 live cuttings to be planted on-site.
