Levee upgrades to build on recent flood risk management efforts

The Sacramento Metropolitan area is one of the most at risk areas for flooding in the United States due to its location at the confluence and within the floodplain of two major rivers. Significant levee improvements, primarily through the construction of 22 miles of seepage cutoff walls, were completed on the American River in 2016 as part of the Water Resources Development Act (WRDA) 96/99 project. Now, this project will add up to 11 miles of bank protection for Lower American River levees. But this portion includes more than just the American River. Sections of the Natomas East Main Drainage Canal (NEMDC), Arcade Creek, and Magpie Creek would be improved to address identified seepage, stability, erosion, and height concerns.

Current Project Activities for American River Levees


  • American River Contract 1

    Objective: This water-side bank protection repair project is located within the City of Sacramento, California. This particular reach of river bank has been identified as a critical erosion risk in the highest velocity reach of the American River within Sacramento and needs to be brought up to modern bank protection standards.

    Duration:  Construction is slated to begin in spring 2021 and continue through October 2021. There is a possibility that this work could take two seasons, but that has yet to be determined. Site preparation work in advance of construction would likely be conducted between October 2020-February 2021.  

    Work Areas: This repair site is located only on the south side of the American River from just upstream of the H Street bridge near Sacramento State University downstream to Paradise Beach.
