bA- Z6 <br />B. Water Distribution and Emergency Storage System <br />Potential Impact: The proposed Project and the Higher Occupancy <br />Scenario may adversely affect the water distribution and emergency storage system <br />around the Project site. (Potentially Significant) <br />Mitigation: The following mitigation measures, as set forth in the FEIR, <br />are hereby adopted and will be implemented as provided in the Mitigation Monitoring <br />Program: <br />Mitigation Measures UT -2.1 and UT -2.2 <br />Finding: Mitigation Measures UT -2.1 and UT -2.2 are feasible and would <br />reduce the potentially significant environmental impact described above to a less -than- <br />significant level. <br />The area surrounding the Project site is served by several old 10 -inch and <br />12 -inch water mains. Water distribution lines around the Medical Center may not be <br />adequately sized to handle the increased demand in flow and pressure from the <br />proposed Project. The system around the Kaiser site is complex and its flows would be <br />altered by the new building components and project phasing. While the City believes <br />there is sufficient existing water pressure and supply under normal service conditions, <br />increased demand from expansion of the Medical Center (under either Kaiser's <br />projected employment figures or the Higher Occupancy Scenario), coupled with <br />emergency service conditions, would likely exceed the capabilities of the water <br />distribution and emergency storage system in the project vicinity. <br />The mitigation measures would reduce the potential impact described <br />above to less than significant levels by using the City's water distribution model and <br />design standards to evaluate the effect of each new building on pipe capacities, water <br />storage tank requirements, and pump station capacity. To avoid any impacts on the <br />City's water distribution and emergency storage system, Kaiser would be responsible <br />for the cost of analysis, design, and construction of all necessary upgrades and new <br />water transmission and distribution systems in accordance with City Engineering Policy <br />Standards and Guidelines to adequately serve the project. In addition, Kaiser would be <br />responsible for the cost of analysis, design, and construction of a new water tank and <br />pump station in accordance with City Engineering Policy Standards and Guidelines to <br />adequately serve the proposed project during emergency service conditions. <br />The potential impact of the Project as contemplated in the Higher <br />Occupancy Scenario would be similar to the potential impact of the Project as proposed, <br />because the layout of the Project as contemplated in the Higher Occupancy Scenario <br />would be similar to the layout of the Project as proposed. Likewise, the mitigation <br />measure would be similarly effective with respect to the Project as proposed and the <br />Project as contemplated in the Higher Occupancy Scenario. <br />14 <br />
