W A 7 E R E N E R G Y I I f E RIVERSIDE PUBLIC UTILITIES Board Memorandum PUBLIC U T I L I T I E 5 BOARD OF PUBLIC UTILITIES DATE: September 21, 2012 ITEM NO: 6 SUBJECT: CONSTRUCTION OF THE ORANGE STREET, WATKINS DRIVE AND MISSION INN AVENUE WATER MAIN REPLACEMENT PROJECTS ISSUE: That the Board of Public Utilities consider approval of the capital expenditure in the amount of$560,000 to construct the Orange Street, Watkins Drive and Mission Inn Avenue Water Main Replacement Projects. RECOMMENDATION: That the Board of Public Utilities approve the capital expenditure of$560,000 for Work Order Nos. 1120005, 1120006 and 1120007,which includes all design and construction costs for the Orange Street,Watkins Drive and Mission Inn Avenue Water Main Replacement Projects. BACKGROUND: The work identified on Orange Street, Watkins Drive and Mission Inn Avenue will be constructed by the Riverside Public Utilities (RPU) Water Division's field forces. This project is part of RPU's ongoing water main replacement program to replace aging and undersized water mains and improve fire protection. In particular,the pipelines to be replaced as part of this project are undersized and have experienced numerous leaks over the past few years. The detailed project locations are shown on Attachment 1. The work on Orange Street will occur between Spruce Street and Russell Street and will generally entail the construction of approximately 400 linear feet of eight-inch ductile iron pipe,four water services and all other related fittings and appurtenances. The work on Watkins Drive will occur near the Interstate 215160 freeway ramps,and will generally entail the construction of approximately 200 linear feet of 12-inch ductile iron pipeline, one water service and all other related fittings and appurtenances. The work on Watkins Drive is within the Caltrans right-of-way, as well as the County of Riverside. Appropriate encroachment permits have been obtained from each of these agencies. The work on Mission Inn Avenue will occur between Brockton Avenue and Chestnut Street and will generally entail the construction of approximately 400 linear feet of twelve-inch ductile iron pipe, four water services, one fire hydrant, as well as all other necessary fittings and appurtenances. Once the new water pipelines are installed, RPU will be responsible for trench resurfacing. The trench resurfacing will be in accordance with Publics Works paving standards. Due to the relatively small size of the project areas,the trench resurfacing work will be performed by the Public Works Department Streets Division. However, if the backlog of Public Works Department Streets Division projects precludes the paving to occur on schedule,staff will solicit paving bids from RPU's Contractors' Panel. A budgetary estimate for the paving work has been included in this authorization.
