The area surrounding the Project site is served by several old 10- inch and 12 -inch water mains. Water distribution lines around the Medical Center may not be adequately sized to handle the increased demand in flow and pressure from the proposed Project. The system around the Kaiser site is complex and its flows would be altered by the new building components and project phasing. While the City believes there is sufficient existing water pressure and supply under normal service conditions, increased demand from expansion of the Medical Center (under either Kaiser's projected employment figures or the Higher Occupancy Scenario), coupled with emergency service conditions, would likely exceed the capabilities of the water distribution and emergency storage system in the project vicinity. The mitigation measures would reduce the potential impact described above to less than significant levels by using the City's water distribution model and design standards to evaluate the effect of each new building on pipe capacities, water storage tank requirements, and pump station capacity. To avoid any impacts on the City's water distribution and emergency storage system, Kaiser would be responsible for the cost of analysis, design, and construction of all necessary upgrades and new water transmission and distribution systems in accordance with City Engineering Policy Standards and Guidelines to adequately serve the project. In addition, Kaiser would be responsible for the cost of analysis, design, and construction of a new water tank and pump station in accordance with City Engineering Policy Standards and Guidelines to adequately serve the proposed project during emergency service conditions. The potential impact of the Project as contemplated in the Higher Occupancy Scenario would be similar to the potential impact of the Project as proposed, because the layout of the Project as contemplated in the Higher Occupancy Scenario would be similar to the layout of the Project as proposed. Likewise, the mitigation measure would be similarly effective with respect to the Project as proposed and the Project as contemplated in the Higher Occupancy Scenario. C. Wastewater Collection System, Transmission System and Treatment Capacity Potential Impact: The proposed Project and the Higher Occupancy Scenario would result in increased wastewater flows from the project site. While there is sufficient capacity at the wastewater treatment plant to accommodate the additional flows from the Master Plan, the number of buildings, their locations, and their sequencing may adversely affect the local wastewater collection system and transmission system. (Potentially Significant) Mitigation: The following mitigation measure, as set forth in the FEIR, is hereby adopted and will be implemented as provided in the Mitigation Monitoring Program:
