Approve the project plans (Attachment A) and specifications (Attachment B) for Jeffrey Sewer and Water Replacement, Specification Number 1000090; and 2. Authorize staff to advertise for bids; and 3. Authorize the City Manager to award the Construction Contract pursuant to Section 3.24.190 of the Municipal Code for the bid total, if the lowest responsible bid is within the publicly disclosed funding amount of $2,410,000; and 4.

DISCUSSION Background Replacement and rehabilitation of wastewater collection pipes is part of an ongoing program to maintain aging and deteriorating infrastructure. This program has several objectives: 1) ensure reliable removal of waste; 2) reduce the need for emergency repairs; 3) reduce the need for preventive maintenance; and 4) ensure uninterrupted wastewater flow without health hazard or effluent leakage. This project will accomplish these objectives for part of the City’s wastewater collection system. Replacement of water distribution pipes and related facilities is an ongoing program to replace aging, substandard, and deteriorating infrastructure, with the added benefit of lowering costs and reducing customer impacts associated with emergency repairs. This program has several objectives: 1) ensure reliable water service; 2) reduce the need for emergency repairs; and 3) and to enhance available fire flows. The Project The Jeffrey Sewer and Water Replacement Project (Project) proposes replacement of approximately 3,178 lineal feet of sewer main on Westmont, Jeffrey, Cerro Romauldo, and Tassajara (Attachment D). The existing sewer pipes planned for replacement work have been video inspected and confirmed to have reached the end of their useful life. Item 6 Packet Page 61 The Project also proposes to replace 2,571 lineal feet of water main on Jeffrey and Cerro Romauldo. The waterlines that will be replaced with this Project are substandard (undersized) and deteriorated. Their replacement will eliminate capacity limitations and improve water flow. Replacing these waterlines will result in lower costs to the City and reduced customer impacts associated with emergency repairs. Reducing or eliminating the number of required emergency repairs provide more time for maintenance staff to complete preventive maintenance, which prolongs the expected service life of Water Distribution facilities and equipment. This Project also includes an additive alternate bid item. With additive alternate bid items, the contractors provide cost of items of work and once known, the City will make the determination whether to award this portion of the work. This Project’s additive alternate bid items include the installation of 255 lineal feet of sewer main by open trenching and 308 lineal feet of sewer main by pipe bursting. Pipe bursting installs a sewer pipe inside the existing sewer pipe resulting in a new sewer pipe of the same or greater size than the prior sewer pipe size. Previous Council or Advisory Body Action This Project was identified in the 2019-21 Financial Plans that were approved by Council. Policy Context The City Council approved the Wastewater Collection System Infrastructure Renewal Strategy in January 2016.
