Project Award Honorable Mention: ENGEO acknowledged for Public Large Budget category for Goldfields 200-year Levee Project

Goldfields 200 Year Levee Project, Marysville, CA

The alarm was sounded when an engineering evaluation of the Yuba Goldfields revealed that there was a vulnerability in the flood control system in Reclamation District 784 (RD 784). TRLIA heard the alarm loud and clear; there was no way that they would allow a breach in the tailings piles within the Yuba Goldfields to circumvent the levees protecting the communities of Linda, Olivehurst, Arboga, and Plumas Lake!  To protect these communities and the integrity of decades of levee improvements, TRLIA assembled a team of geotechnical, civil, hydrologic, and environmental consultants to fix the problem. The solution: a new, 2.6 mile long levee – the 200-year Goldfields Levee Project. This outstanding project not only shored up the local flood protection system but also extended the State Plan of Flood Control to true ‘high ground’.


The project included construction of a new 2.6 mile long levee, effectively extending the Yuba River South Levee to natural high ground. The levee was constructed to provide protection during a 200-year flood event with a flow in the Yuba River of 180,000 cubic feet per second. During a 200-year flood event, the new levee was designed to contain flood water that could emanate from a breach in the tailings piles within the Yuba Goldfields. The project provides flood protection to the communities of Linda, Olivehurst, Arboga, and Plumas Lake, allowing these communities to maintain their eligibility for low-cost flood insurance and be free of flood-related building restrictions.


During design, ENGEO mapped the geomorphology and explored the subsurface conditions with a combination of borings, test pits, and geophysical surveys. The levee alignment was split into seven representative reaches to evaluate slope stability, seepage, and settlement. Eight cross sectional models and one plan view model were developed and analyzed. Under-seepage was identified as the primary geotechnical concern, which required mitigation for the levee to meet the requirements of California’s Urban Levee Design Criteria (ULDC).


The levee has 3:1 (horizontal:vertical) landside and waterside slopes, a 20-foot-wide crown, and, at its tallest point, is approximately 17 feet tall. To mitigate under-seepage effects, the project included a soil-bentonite (SB) cutoff wall under over 80 percent of the entire length of the levee alignment. Cutoff wall depths ranged from approximately 35 to 70 feet deep. Where the levee tied-in into the existing Yuba River South Levee, a seepage berm was included along the land-side corner of the connection point to provide additional under-seepage mitigation because of the potential for concentrated seepage. Observation wells were installed at the toe of the seepage berm to provide redundancy and allow for monitoring of under-seepage pressures during a future flood event.


The levee crossed over a Brophy Water District irrigation canal that provides irrigation water to farmers south of the project area. At this crossing, a box culvert and gate riser structure were constructed and a portion of the canal was re-routed. A temporary diversion was utilized during construction so that there were no impacts to the irrigation district’s customers while the levee was being built.


Other project features included toe roads, ramps, a pipe crossing, and three detention basins. The detention basins also served as borrow sources for levee embankment fill during construction.
