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 North bank of the Lower American River (LAR) in Sacramento, California (CA).
