tie into the trunk line near the intersection of the Arroyo Mocho <br /> and the S.P. railroad tracks (Point 14, Figures 3 and 4). A <br /> new 15" line should be provided, along the Southern Pacific <br /> Railroad track south of the Arroyo Mocho from Santa Rita Road to <br /> pick up the sewage flow generated from these areas. The 15" line <br /> size is based on the 1967 Black Report assumption that the 1.75 MGD <br /> reserve may be flowing in at this point in the system. <br /> <br />WEST OF SANTA RITA ROAD <br /> <br />1. New Stoneridge Line - Bypass at Existing East Amador Trunk - Full <br /> Buildout <br /> <br /> In order to alleviate the overloading of the trunk iine, a new <br /> line should be provided running north from the treatment plant to <br /> Johnson Drive, east along Stoneridge Drive, and connecting to the <br /> existing trunk at Hacienda Drive (See Figure 4). This new line <br /> would pick up a large portion of the flow generated by HBP (Phase II), <br /> the Meyer Business Park, the Pleasanton Park, and other areas along <br /> Hopyard Road by intercepting the existing 18" line flowing down <br /> Hopyard Road. Figure 4 compares, with the addition of the Stoneridge <br /> line bypass, the capacity of the line against the flow generated <br /> assuming full projected buildout. <br /> <br /> In Figure 4, the new Stoneridge line is extended down Hacienda <br /> Drive and tied into the trunk line. With this new Stoneridge bypass <br /> line, the flow in the existing trunk between Hacienda Drive and <br /> treatment plant at full buildout will be at or below the capacity <br /> of the existing line. The last reach will have a flow of 8.8 MGD <br /> compared to a maximum capacity of 11.0 MGD. The total flow for the <br /> two lines will be 8.8 + 11.0 = 19.8 MGD. <br /> <br />-9- <br /> <br /> <br />
