Bouldin Island Multi-Benefit Levee Setback Project

Reclamation District No. 756 is advancing the Bouldin Island Multi-Benefit Levee Setback Project along the Mokelumne River in Stockton, California, with a focus on ecological enhancement and infrastructure resilience. The project involves a 5,000-linear-foot levee setback to establish a waterside planting bench designed to restore Shaded Riverine Aquatic habitat, while simultaneously rehabilitating the levee structure to meet Bulletin 192-82 standards for long-term sustainability. Concurrently, the District’s Camp 5 Pump Station will be replaced to ensure continued flood protection and water management. Construction is scheduled to commence on May 31, 2025, with all in-water work confined to the window of August 1 through October 31 to align with fish species life cycles and minimize ecological disruption. Work activities are restricted to the months of May through November over two consecutive years to accommodate environmental constraints and regulatory permitting timelines. All project activities must comply with a comprehensive set of environmental, safety, and operational mandates. A Stormwater Pollution Prevention Plan is required, including sediment control, re-vegetation, and spill response protocols. Dust and air quality mitigation measures—such as dust suppressants, speed limits on unpaved roads, and EPA-compliant equipment with idling restrictions—are mandatory to meet San Joaquin Valley Air Quality Management District thresholds. Hazardous materials must be stored in original containers with intact labels and managed under secondary containment systems. The project must adhere to CEQA, CESA, and federal protections for Waters of the U.S., and includes biological monitoring by qualified biologists to safeguard special-status species, with buffer zones and real-time oversight in place. Cultural resource protections require immediate work stoppage and consultation with the Native American Heritage Commission and Most Likely Descendants upon discovery of human remains. Training for all personnel on environmental and cultural resource protocols is required, along with strict site operation rules including no-smoking zones, equipment maintenance to prevent fluid leaks, and fire prevention measures. Final inspection and acceptance occur on-site at Bouldin Island under the authority of the District as Lead Agency. Submissions for environmental documentation are due by February 26, 2026, via the CEQAnet portal and hardcopy delivery to MBK Engineers in Sacramento. No contract value, pricing structure, or federal acquisition regulation clauses are specified in the available documentation, and no contracting officer or financial administration details are provided.
