Maintenance of Northwestern Basin Rehabilitation (L02P22)

The project involves the rehabilitation of the Northwestern Basin in the Las Flores Unincorporated Area of Orange County, California, with work focused on repairing and upgrading critical infrastructure components. Activities include removing and replacing a damaged corrugated metal pipe (CMP) riser, installing grout from the access road to the riser, clearing vegetation from the concrete turn-around pad, replacing existing rip rap, inspecting and clearing blockages in the weep holes of the retaining wall, and injecting grout into voids beneath the existing pipe. Construction is expected to last approximately five months and is scheduled for completion in spring 2027, with minimal disruption as all staging will be conducted on-site and only eight truck trips are anticipated. Best Management Practices will be implemented throughout the project to ensure environmental compliance. The work is classified under CEQA as a Class 1 exemption for existing facilities, and the project is exempt from fees under state codes governing fish and game and government operations. The contracting entity is Orange County through its Public Works and Construction division, with no formal solicitation number issued, indicating this is a forecasted project rather than an active procurement. Administrative operations are managed from the 601 North Ross Street office in Santa Ana, and payment can be made via cash, check, or credit using receipt number 30-01/20/2026-0030. While the project’s scope and timeline are detailed, no contract value, pricing structure, or specific payment office details are provided. Inspection and acceptance occur on-site, with government staff responsible for oversight, and no formal contracting officer’s representative or technical representative roles are designated. Environmental documentation, including a Notice of Exemption and CDFW No Effect Determination, must be submitted as part of compliance, but no formal contract clauses, evaluation criteria, technical specifications beyond CEQA exemptions, or packaging and labeling standards are included. The project is executed under local jurisdictional authority without reference to federal acquisition regulations, military standards, or federal procurement mechanisms.
