Sacramento North River Levee - Geotechnical Engineering and Material Testing

West Sacramento is a vibrant riverfront community centrally located in Northern California. West Sacramento shares the Sacramento River with neighboring Sacramento, with the deep water ship canal serving the Port of Sacramento. Incorporated in 1987, West Sacramento encompasses approximately 22 square miles, with a population just over 55,000. The West Sacramento Federal Project (Project) was authorized in the 2016 Water Infrastructure Improvements for the Nation Act. The Project has a current estimated cost of $2.01 billion. Before the Project received a New Start designation, WSAFCA and State of California (State) invested nearly $210 million in advanced construction to immediately reduce flood risk to the 55,000 residents, property, and businesses in the City. This advanced construction included the first component of the authorized Project, the Southport Levee Improvement Project, and three segments in the north area of the City. The Corps has received approximately $153,000,000 to date in pre-construction engineering and design (PED) and construction funds for the Federal Project, which is being used to design and construct the next increments of the Federal Project, the Yolo Bypass East Levee project and Sacramento River North Levee (SRNL) 1S Contract. The SRNL 3E erosion protection project is the next phase of the Project. SRNL was studied at a feasibility level in the West Sacramento Project General Reevaluation Report. The levee seepage improvements project is currently at the 65% design phase. In advance of additional federal appropriations, WSAFCA intends to advance design of the erosion protection phase of the Project. The geotechnical subsurface investigations requested in this proposal will be used to determine recommended future improvements for design and construction along the west bank of the Sacramento River.
