Marysville Ring Levee Improvements

The Marysville Ring Levee Phase 2A North, 2A South, and 2B &3 projects presented substantial challenges in upgrading critical infrastructure to enhance flood protection along the Feather River in Marysville, CA. Phase 2A North required the construction of a seepage cutoff wall extending approximately 37 feet deep along the riverside toe of the levee, connecting seamlessly to an existing cutoff wall spanning from STA 195+68 to STA 208+11.
 
Concurrently, the project aimed to reconstruct the levee crown and slope to a 3:1 slope, extending it 10 feet towards the river, using specified fill materials. Challenges included the removal of stone and concrete rubble, replacement of asphalt concrete pavement, implementation of erosion control measures, and the temporary reconstruction of the bike trail and safety rail—all within stringent environmental and engineering guidelines.
 
Phase 2A South involved the partial degradation of the waterside embankment, necessitating the construction of a cutoff wall within the levee embankment degrade and subsequent reconstruction with an impervious slope blanket. The project scope encompassed extensive site security, restoration efforts, and utility management, including the replacement and protection of critical infrastructure such as sewer lines and fiber optics.
 
Phase 2B & 3 further extended these efforts, focusing on the installation of a cutoff wall using advanced deep mixing methods and addressing earthwork challenges through strategic material handling and compaction techniques. Utility management remained a critical aspect, particularly with the operation of a nearby pump station and the replacement of discharge pipes with durable welded steel, creating long-term reliability and performance.

To tackle these challenges on this geotechnical and heavy civil construction project, our team implemented a comprehensive solution. We employed advanced deep mixing methods to construct robust cutoff walls, ensuring continuity and integrity. We used precision earthwork techniques to reconstruct levee crowns and slopes, strictly adhering to specified dimensions and material requirements. We removed debris and replaced infrastructure, such as asphalt concrete paved roads, with precision to maintain structural integrity and functionality.

To control erosion, we meticulously seeded and implemented environmental safeguards to stabilize disturbed areas and protect the surrounding ecosystem. We strategically sourced and transported suitable borrow materials to facilitate efficient embankment construction, enhancing the levee’s stability and resilience against potential flood events.

We prioritized utility management, planning and executing protection, relocation, or replacement of critical infrastructure with great care. Coordination with local authorities and utility providers ensured minimal disruption and enhanced safety during construction.

Implementing these solutions yielded significant results for the Marysville Ring Levee project. We achieved enhanced flood protection capabilities by constructing robust slurry cutoff walls, effectively mitigating seepage risks and bolstering overall levee integrity. The extended levee crowns and improved slopes provided greater resilience against floodwaters, enhancing the levee’s ability to withstand potential disasters.

We minimized environmental impacts through comprehensive erosion control measures and careful management of construction activities, adhering to regulatory standards and preserving local habitats. We successfully replaced and protected critical utilities, ensuring uninterrupted service and enhancing community safety.

Overall, the project’s success was highlighted by improved infrastructure resilience, positive stakeholder feedback, and adherence to stringent engineering and environmental standards. The Marysville Ring Levee project stands as a testament to effective collaboration, engineering innovation, and dedication to community safety and environmental stewardship.
