Yolo Bypass Wildlife Area Habitat and Drainage Improvements Project

The project involves major habitat and drainage improvements within the Yolo Bypass Wildlife Area in West Sacramento, California, led by the California Department of Fish and Wildlife to enhance wetland management and agricultural operations. Key components include installing new water control structures, expanding canals, replacing existing culverts, raising road grades, separating dual-function ditches, relocating and installing water pumps, and constructing two con-span bridges. An addendum modifies the original plan by eliminating the cross canal pump station, replacing it with passive drainage structures to reduce long-term costs and environmental impacts while maintaining functionality. The project is located near Interstate 80 and the Sacramento Deep Water Ship Channel and is subject to multiple environmental regulations, including the Clean Water Act (Sections 401 and 404), the Endangered Species Act (Section 7), and the National Historic Preservation Act (Section 106), requiring coordination with the U.S. Fish and Wildlife Service, State Historic Preservation Officer, and culturally affiliated tribes such as the Federated Indians of Graton Rancheria and Yocha Dehe Wintun Nation. Environmental analyses under CEQA are completed, with mitigation measures documented in appendices covering habitat maps, historical resources, and monitoring protocols. The project is funded through a combination of U.S. Army Corps of Engineers Section 1135 funds and NAWCA grants, with no formal contract pricing or line items identified in the available documentation, suggesting the work may be executed through interagency agreements or grant-based funding mechanisms. Oversight is managed by the CDFW’s Region 3 – Bay Delta office, with Garrett Spaan as the primary point of contact, and environmental compliance, worker safety (Cal/OSHA), and stormwater management (SWPPP) are critical operational requirements. No formal contract clauses, evaluation factors, or contracting officer representative appointments are specified, indicating the document reflects an environmental planning and approval record rather than a solicitation or awarded contract.
