W A T E R E R £ R G Y i i F RIVERSIDE PUBLIC UTILITIES Board Memorandum PUBLIC UTILITIES BOARD OF PUBLIC UTILITIES DATE: October 05, 2012 ITEM NO: 6 SUBJECT: OVERHEAD LINE RELOCATION PROJECT FOR RYAN BONAMINIO PARK AT THE TEDUESOUITE ARROYO-WORK ORDER NO. 1110587 ISSUE: Board of Public Utilities approval is requested for Work Order No. 1110587. RECOMMENDATION: That the Board of Public Utilities approve the estimated capital expenditure of $1,010,000 for Work Order No. 1110587 to relocate and reconfigure existing 69 kV overhead facilities to accommodate the construction of the Ryan Bonaminio Park at the Tequesquite Arroyo improvements. BACKGROUND: There is an existing overhead 69 kV wood pole line near Tequesquite Avenue, northerly of Palm Avenue, which bisects the open space proposed for the new Ryan Bonaminio Park at the Tequesquite Arroyo (Project). The work proposed will consist of relocation of the 69 kV wood pole line out of the proposed Project, acquisition of any necessary easements, and installation of approximately 10,500 linear feet of Aluminum Conductor Composite Core Cable (ACCC). As illustrated in the attachment, the existing 69 kV wood pole line crosses diagonally over City property and in an open field. The line is not within an existing easement area and instead is co-located on City property. The line will be relocated to the street right-of-way in order to avoid interference with the improvement of the property for the Project, as the operation of the Park could interfere with proper maintenance and operation of the 69 kV line. ACCC cable incorporates advanced technologies resulting in lighter weight cable, increased current carrying capabilities, and enhanced strength over traditional 69 kV aerial conductors. Consistent with the Riverside Public Utilities' (RPU) Strategic Plan goal to maximize the use of technology to improve utility operations, staff has recommended this new cable type be used on this project. Engineering was performed in collaboration with RPU staff and a consultant from the Consultant's Panel. Electrical work will be performed by RPU field forces. Civil construction will be performed by contract crews from the Contractor's Panel. FISCAL IMPACT: The capital expenditure for the project is estimated to be $1,010,000 and is as follows: % of Total Construction Contract-Civil Work $115,596 12% Construction RPU-Electric Overhead $730,559 72% Design, Permits, Construction Management, Ins ection $72,027 7% Contingency 10% $911818 9% Subtotal: $1,010,000 100% Sufficient funds are available in the Major Transmission Line Project Account No. 6130000-470620.
