W A7 E R E N E R G Y L I F E RIVERSIDE PUBLIC UTILITIES Board Memorandum PUBLIC UTILITIES BOARD OF PUBLIC UTILITIES DATE: October 19, 2012 ITEM NO: 4 SUBJECT: CONSTRUCTION OF THE STEWART INTAKE DRAIN RELOCATION PROJECT ISSUE: That the Board of Public Utilities consider approval of a capital expenditure in the amount of$385,000 for the construction of the Stewart Intake Drain Relocation Project. RECOMMENDATION: That the Board of Public Utilities approve the capital expenditure of $385,000 for Work Order No. 1108632, which includes all design, utility potholing, railroad flagmen, construction, change order contingencies, construction management, inspection and geotechnical testing for the Stewart Intake Drain Relocation Project. BACKGROUND: The Stewart Intake Facility is located in the City of San Bernardino and serves an important role in regulating the water pressure within Riverside Public Utilities' (RPU) San Bernardino Supply Pipeline. The overflow and runoff from the Facility currently drains through a 30-inch concrete pipe located within the Union Pacific Railroad right-of-way to a storm channel located in Hunts Lane. The cities of Colton and San Bernardino, in association with the San Bernardino Associated Governments (SANBAG), are constructing a railroad grade separation at Hunts Lane over the railroad tracks. The proposed bridge foundation is in conflict with the existing Stewart intake drain line and will, therefore, require relocation of the drain line. The railroad grade separation project is located on Hunts Lane southeast of the Interstate 10 and Interstate 215 interchange at the Union Pacific Railroad crossing (Attachment 1). The Stewart Intake Drain Line Relocation project will involve the construction of approximately 210 linear feet of 30-inch reinforced concrete pipe within the Union Pacific Railroad right-of-way and an easement on private property, construction of a junction structure into an existing San Bernardino storm drainage facility, and abandoning 500 linear feet of existing 30-inch concrete pipe. This project has a tight timeline to meet the schedule of the Hunts Lane Railroad Grade Separation project that is currently underway. Staff has solicited construction bids from RPU's Contractor's Panel, and the lowest responsive bidder will be selected to perform the work of the project. FISCAL IMPACT: The Riverside Public Utilities is responsible for costs associated with its utility conflicts within the Union Pacific Railroad right-of-way. The capital expenditure for the entire project is estimated to be $385,000. This includes all design, utility potholing, railroad flagmen construction, change order contingencies, construction management, inspection and geotechnical testing, as summarized in the following table:
