I F F RIVERSIDE PUBLIC UTILITIES WON Board Memorandum PUBLIC UTILITIES BOARD OF PUBLIC UTILITIES DATE: OCTOBER 2, 2015 ITEM NO: 7 File ID — 15 -3128 — C SUBJECT: CONSTRUCTION OF THE CREST AVENUE AND HEDRICK AVENUE WATER MAIN RELOCATION PROJECT— WORK ORDER NO. 1522100 FOR $123,000 ISSUE: The issue for Board of Public Utilities consideration is to approve a capital expenditure in the amount of $123,000 for Work Order No. 1522100 to construct the Crest Avenue and Hedrick Avenue Water Main Relocation Project. RECOMMENDATION: That the Board of Public Utilities approve a capital expenditure of $123,000 for Work Order No. 1522100, which includes all design, construction, paving, contract administration, inspection and construction contingency costs for the Crest Avenue and Hedrick Avenue Water Main Relocation Project. BACKGROUND: The Riverside Transmission Reliability Project (RTRP) is a joint project with Southern California Edison (SCE) which provides Riverside Public Utilities (RPU) a second connection to the state electric transmission grid to address long -term capacity and reliability needs of the City's electric utility system. SCE's portion of the project includes construction of approximately 10 miles of double- circuit 230kV transmission lines and a 230kV switchyard. RPU's portion of the project includes the installation of approximately 10 miles of 69kV sub - transmission lines, construction of a new substation, improvements to five existing substations, relocation of existing distribution lines and installation of new telecommunication lines. A segment of the proposed 69kV improvements are in conflict with an existing 4 -inch Asbestos Cement (AC) water main located in the parkway near the intersection of Crest Avenue and Hedrick Avenue and needs to be relocated in advance of the RTRP. In order to facilitate the water main relocation, a new pipeline will be constructed within Crest Avenue, which will enable the abandonment of approximately 330 linear feet of existing 4 -inch and 6 -inch 1950's vintage AC water pipeline in the parkways of Crest and Hedrick Avenues. The water main relocation work will generally entail the construction of approximately 300 linear feet of 8 -inch ductile iron pipe, one fire hydrant, two water services and two system connections, along with all necessary fittings and appurtenances. These new improvements will allow approximately 330 linear feet of existing 4 -inch and 6 -inch AC pipeline to be abandoned. The work identified will be constructed by the Water Division's field forces. Other than routine service tie - overs, this project is not expected to disrupt service to RPU water customers.
