Natomas Basin - Reach A

The U.S. Army Corps of Engineers (USACE), in partnership with the California Central Valley Flood Protection Board (CVFPB), California Department of Water Resources (DWR) and the Sacramento Area Flood Control Agency (SAFCA), will be constructing 3.5 miles of levee improvements along the Garden Highway levee from Farm Rd to Gateway Oaks Dr. This work is part of the American River Watershed Common Features - Natomas Basin project authorized by Congress in 2014.  

Geotechnical engineering analyses have shown that the levees are susceptible to seepage and many portions of the levee have significant landside slope stability and long-term operations and maintenance concerns. Upcoming levee improvements are expected to begin in 2022, and will address identified deficiencies by constructing an adjacent levee to widen the existing levee, installing seepage cutoff walls up to 145 feet deep, and constructing landside seepage berms.
