BACKGROUND: The Riverside Public Utilities Plaza Substation reliability issues were addressed in the Electric System Master Plan Study, Section UG1 delivered in 2009. As a result, expansion of the Plaza was recommended. Additionally, the Public Works Riverside Avenue Grade Separation Project requires that Circuits 1251 and 1253, currently in an underground duct bank on Elizabeth Street, be relocated to adjacent Merrill Avenue. In order to accommodate these requirements, a new underground steel casing and conduit bank must be installed south of the Substation, crossing under the railroad tracks and extending to Merrill Avenue. Another underground duct bank will be installed east along Merrill Avenue, reconnecting with existing conduits at Riverside Avenue. Riverside Public Utilities (RPU) staff completed the project engineering with consideration given to the surrounding aesthetics, while ensuring that such consideration did not impact the cost of construction.
