Upper Yuba River Levee  Improvement Project

The Upper Yuba River Levee Improvement Project completed a levee system designed to provide 200-year flood protection for 40,000 residents in South Yuba County [map].

The need for additional improvements on Yuba River levees was indentified and  improvements include seepage remediation [cutoff wall and seepage berm], corrections to slope geometry, and erosion protection on four levee segments [segment map]. Construction was completed in 2012.

Originally, the project was expected to cost $68 million.  Based on levee design changes and favorable construction bids, the revised project cost was approximately $36 million. Of that amount, $25 million was paid for by the State Department of Water Resources. As part of its funding agreement with the state, TRLIA provided a 30 percent cost share for the project, or approximately $11 million. The local share was  covered through reimbursement and credit from the State for prior construction work, and funding from prior development agreements.

 In early 2013, we were notified that the project was recognized as the Project of the Year 2012 by the American Society of Engineers - Sacramento Section..
