Subsequently, the City Council included the comprehensive technical study in the two - year work plan, and on February 16, 2016, authorized a contract with RMC to complete the study to determine how the utilities could be extended. The study is now complete. DISCUSSION: The completed RMC study is attached to this report as "Attachment 1." Figure 4 on page 10 of the study indicates graphically how public water pipelines can be constructed to serve each property in the Happy Valley area while complying with the Pleasanton Municipal Code requirements that each property have a direct connection to a public water main. Figure 6 on page 15 of the study shows how the sewer system can be extended to serve each property, again in a manner compliant with the Pleasanton Municipal Code requirement that each property have a direct connection to the pubic sewer main. Figures 4 and 6 are both accurate representations of how to deliver public water and sewer to each property in the Happy Valley Area. For those that require more details, the study also includes technical analysis to ensure the pipelines proposed in Figures 4 and 6 will provide the services as required is further discussed below. Adequacy of Existing Water and Sewer Infrastructure The study reviewed existing utilities to determine if any improvements or upgrades are necessary outside the Happy Valley Area to accommodate the extended services. The study determined the existing utilities were sized appropriately to be extended without requiring any upgrades. In the case of the water, existing City water tanks provide adequate storage to meet peak demands of the extended service area with no upgrades required. Proposed Water and Sewer Infrastructure Extensions For water, the study also considered pressures, pipe sizes, water flow rates, etc. that are necessary to provide adequate water pressure at each property, and water flow rates necessary at each fire hydrant placed along the alignment of the pipeline at spacing consistent with City standards. In the case of sewers, it was determined that each proposed pipeline would work with gravity flow and not impact the downstream facilities including the pump stations in the City's existing sewer system. All proposed sewer pipes are sized to both maintain adequate flushing velocity and allow maintenance with existing City -owned equipment. (Note: Due to the area topography, some Happy Valley properties may need to install individual sewer pump facilities on their property to lift their waste flows to the gravity sewer main to be located within the streets.) Finally, the study considered two alternatives; 1) Serve each property in the area with water and sewer as they currently exist (92 parcels), and 2) Serve each property with water and sewer at build -out as considered in the 2002 Happy Valley Specific Plan (125 parcels.) It should be noted that the study revealed there is not a lot of difference between the piping systems needed in each of the two scenarios, and therefore the estimated costs are similar. Page 3 of 7
