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.
