W A T E R E N E3W& RIVERSIDE PUBLIC UTILITIES Board Memorandum P U B L I C U T I L I T I E S BOARD OF PUBLIC UTILITIES DATE: March 5, 2010 ITEM NO: 4 SUBJECT: CIRCUIT 1290 RELIEF AT LA SIERRA AVENUE BETWEEN COCHRAN AND CLARKSDALE AVENUE —WORK ORDER NO. 1014689 ISSUE: Board approval is requested for Work Order No. 1014689. RECOMMENDATION: That the Board of Public Utilities approve the estimated capital expenditure of $94,664 for Circuit 1290 Relief project, which encompasses a small area from Cochran and Clarksdale Avenues along La Sierra Avenue, and all surrounding areas shown on the attached map. BACKGROUND: This upgrade project is taking place due to Circuit 1290 experiencing an overload of 102% during peak times, along with low voltage at the end of the circuit. The cable at select locations is too small to handle future load in the area and needs to be upgraded. Since there is a tie to another circuit (Circuit 1285) at one of these locations, it was found to benefit the area to place an above ground switch for faster response in transferring load in times of emergency. Upgrading the cable now will allow growth to proceed in the area and not be affected by an outage from the smaller cable being burned up. The scope of the work involving the upgraded circuit consists of installing approximately 1 switch, 1 PJC, and replacing approximately 4200 feet of underground cable. Engineering was performed by staff and construction will be performed by either Utility staff or by contractors using the Utility Contractor's panel. FISCAL IMPACT: The total estimated cost for Work Order No. 1014689 is $94,664. % Of Total Construction-(Contract) Electric Conduit & Sub-Structures $18,000.00 19.02% Construction-Cables, Structures $59,229.00 62.56% Design, Construction Management, Inspection, Easement Acquisition $17,435.00 18.42% Subtotal: $94,664.00 1 100% Funds are budgeted and available for this project in the Line Rebuilds Account No. 6130000-470603.
