Alvarado Trunk Sewer SDP (PTS No. 596507)

The City of San Diego is undertaking a sewer infrastructure project to replace approximately 5.0 miles of gravity trunk sewer using both open trench and trenchless techniques, including slip-lining and micro-tunneling, with average trench depths of 20 feet and jacking pits reaching 19 to 26 feet. Concurrently, 1.6 miles of existing sewer main will be abandoned. Work primarily occurs within public rights-of-way and city-owned utility easements, with a limited 950 linear foot segment extending into Adobe Falls Open Space Canyon, where construction access will utilize an existing maintenance path. Staging areas are designated within paved public areas and adjacent developed private property near trenchless pits. Environmental mitigation is central to the project, requiring revegetation of disturbed habitats in the canyon using a specified blend of Riparian and Diegan Coastal Sage Scrub container plants and hydroseed, with ongoing monitoring and maintenance until vegetation establishment meets defined success criteria. The project is governed under the California Environmental Quality Act (CEQA), with a Mitigated Negative Declaration approved as the environmental review document, and associated fees totaling $2,354.75 for Fish and Wildlife and $50.00 for county processing have been paid to fulfill regulatory requirements. The project spans multiple zoning classifications and public lands along a corridor extending from Fairmount Avenue to Alvarado Road near the La Mesa border, with construction activities coordinated through the City of San Diego Public Works Department. No formal contract value, pricing structure, or delivery schedule is publicly documented, and the project is administered under a Site Development Permit rather than a traditional procurement contract, with inspection and acceptance performed on-site by the City as the lead agency. There is no designated Contracting Officer’s Representative, technical officer, or formal payment processing system identified, and the project’s execution relies on compliance with local environmental permits and state-mandated mitigation protocols.
