RECOMMENDATION: That the Board of Public Utilities approve Work Order No. 1706279 in the total amount of $2,450,000 for all design, construction, paving, and construction contingency costs for the Wells and Cypress Water Main Replacement Project (Phase 1). BACKGROUND: On July 10, 2017, the Riverside Board of Public Utilities (Board) received a report outlining planned Electric and Water capital improvement projects for fiscal year 2017/18, which included the Wells and Cypress Water Main Replacement Project that entails replacing roughly 3.7 miles of water mains. Due to the reprioritization of projects, this project has been divided into three (3) phases to fit within the budgetary allotments of upcoming fiscal years and to coincide with the planned schedule for Public Works paving projects. The Wells and Cypress Water Main Replacement Project (Phase 1) is part of Riverside Public Utilities (RPU) ongoing water main replacement program to replace old and high priority leaky mains. The project area consists of existing 2, 4, 6, and 8 -inch steel, cast iron, and asbestos cement water mains that were installed between 1926 and 1972. Based on their leak history, age, and size, these water pipelines have been identified as high priority pipelines for replacement to enhance system reliability and improve fire flow capacity. This project will occur ahead of the Public Works Department's (PW) fiscal years 2019/20 and 2020/21 Arterial and Minor Streets Maintenance Projects that entail resurfacing several streets throughout the City. As currently planned, PW project will include the streets covered by this water main replacement project (FY2019/20 — Eddystone Street and Singleton Way; FY2020/21 — Orlando Drive, Citadel Court, Temecula Place, Galway Court, Silverado Place, Remington Drive, Modesto Drive and Daniel Drive). Collaborating with PW provides an opportunity to reduce RPU's overall paving costs. Subsequent phases of this project will be brought for consideration to the Board in future fiscal years.
