American River Common Features, 2016 Flood Risk Management Project, Sacramento, California

The American River Common Features 2016 Flood Risk Management Project, identified by solicitation number A4794, is a comprehensive effort to reduce flood risk in Sacramento, California, by addressing slope stability, seepage, and erosion along the levees of the American and Sacramento Rivers. Managed by the Central Valley Flood Protection Board and the California State Lands Commission, the project involves design refinements to the authorized 2016 ARCF Project. Key technical components include the Magpie Creek Project, the installation of a Piezometer Network, and various erosion contracts, specifically American River Erosion Contracts 3B North, 3B South, 4A, and 4B, as well as Sacramento River Erosion Contract 3. The scope also encompasses the American River and Sacramento River mitigation sites, with specific work including approximately 1,700 linear feet of bank protection along the Sacramento River east levee. The project is governed by strict environmental and land-use regulations, requiring compliance with the California Environmental Quality Act (CEQA) through the certification of Environmental Impact Reports and the adoption of Mitigation Monitoring and Reporting Programs. To facilitate these works on sovereign land, the California State Lands Commission has approved a 49-year General Lease for public agency use, extending through June 22, 2075. The project's execution involves engineering design modifications, footprint expansions, and compensatory habitat mitigation to ensure the stability of the levee systems and the protection of the surrounding watershed.
