Levee improvements to continue at four new sites in 2021

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. The 1997 Sacramento flood events revealed deep under-seepage on the Sacramento River, including in areas that were remediated to address through-seepage with shallow cutoff walls in the early 1990s. 

Construction is set to begin this spring on four new seepage/stability sites, and will improve approximately 1.8 miles of levee. The work will entail installation of seepage cutoff walls on both sides of Business 80/Highway 50 just upstream of Miller Park, on the south side of the little pocket, and on the north side of the big pocket.

This is the second major construction contract to address seepage and stability concerns with the levee between Old Sacramento and the Freeport Regional Water Intake Facility near Sacramento’s Pocket neighborhood. In 2020, construction crews installed nearly three miles of seepage cutoff wall along the Sacramento River East Levee, and a 400-foot-long seepage berm on the landside levee adjacent to Front St. In total, the American River Common Features 2016 project is expected to construct approximately 9 miles of slurry cutoff walls along the Sacramento River East Levee, and will add erosion protection at a number of locations.
