BACKGROUND: Magnolia Substation has served Riverside’selectric system for68 yearsand is scheduled to be decommissioned in 2018 due toobsoleteand unreliable aged infrastructure. The site is deemed unsuitable for a new electric substation and will be vacated for sale. Riverside Public Utilities’ (RPU)existing Fiber Optic Cable Network (fiber network) interconnects through Magnolia Substationalong Central Avenue and Riverside Avenue to the City’s Fire Station #3, located at 6395 Riverside Avenue. The fiber networkisanintegral part of the communication infrastructure that serves RPU’s electricsubstations and other City facilities for voice, video and data services. Since RPU is demolishing and vacating the MagnoliaSubstation property, it is necessary to relocate the fiber network.

An existing splice closure near the intersection of Central Avenue and Riverside Avenue will be utilized to reconnect Fire Station #3 to Plaza Substation. RPU will also utilize existing underground infrastructures along Riverside Avenue and Merrill Avenue to re-establish the fiber network at Plaza Substation.In addition, the Casa Blanca–Magnolia–Riverside Substations overhead fiber network will be spliced at an existing pole to establish the Casa Blanca to Riverside Substations fiber network.
