BACKGROUND: The City of Riverside Public Works Department is currently undergoing final design of a proposed railroad grade separation project along Iowa Avenue between Paimyrita Avenue and Spring Street. This railroad grade separation project will involve the construction of a highway bridge to create an overpass above the existing railroad tracks. The project would require that the existing utilities within the roadway be relocated, including the existing water pipeline facilities. The three affected water pipeline facilities include a segment of Riverside Public Utilities' (RPU) crucial San Bernardino water supply pipeline, a section of the transmission pipeline delivering water from the Electric Street well, and a portion of the water distribution pipeline within Iowa Avenue. Construction of the grade separation project is scheduled to begin at the end of 2011. The water pipeline facilities need to be relocated in advance of that date to clear the way for the grade separation project. Authorization is requested to construct the Iowa Avenue Railroad Grade Separation 12-inch, 16-inch and 48- inch Water Pipeline Relocation Project, Bid No. 6949. The project will generally entail the construction of approximately 1,400 linear feet of 48-inch water pipe, 2,600 linear feet of 16-inch pipe,2,800 linearfeet of 12- inch pipe, 900 linear feet of 8-inch pipe, 135 linear feet of 30-inch steel casing to be bored and jacked beneath the railroad tracks and 135 linear feet of 24-inch steel casing to be bored and jacked beneath the railroad tracks,along with abandonment of the old pipelines. The work will also include the construction of all associated pipeline appurtenances and asphalt paving.
