Mitigation Measure UT -3.1 Finding: Mitigation Measure UT -3.1 is feasible and would reduce the potentially significant environmental impact described above to a less -than- significant level. The projected average daily water demand for the proposed Project at buildout, calculated based on City standards, is 0.209 mgd (234 AFN), absent mitigation measures. Therefore, based upon Redwood City Engineering Policy Standards and Guidelines, the projected average daily wastewater flow for the proposed Project will be some factor less than the average daily water demand. The treatment plant currently has the permitted treatment capacity to handle the projected demand from the proposed Project and the Higher Occupancy Scenario at buildout based on the projected average daily water demand. The wastewater treatment plant has sufficient existing capacity to accommodate the proposed Project or the Higher Occupancy Scenario at buildout. However, the sewer collection and transmission systems are currently functioning at maximum capacities. In some cases, the pipes are functioning under surcharged conditions. The South Bayside System Authority's Maple Street Sanitation Pump Station and transmission pipe from Maple Pump Station to the treatment plant are at capacity during wet weather flow conditions. Because sewer collection and transmission systems are currently functioning at maximum capacities, any increase in wastewater flow could exceed capacity. To reduce the impact of the proposed Project or the Higher Occupancy Scenario on the wastewater collection system to less than significant levels, Mitigation Measure UT -3.1 requires Kaiser to be responsible for the cost of analysis, design, and construction of all necessary upgrades to or replacement of sewer collection and transmission to adequately serve the project. The proposed Precise Plan incorporates Mitigation Measures UT -3.1 by requiring necessary infrastructure or a financial contribution to collect, transmit, and treat wastewater. Wastewater calculations will be derived from the water demand projections. Any necessary infrastructure improvements to sewer collection and transmission systems, treatment and capacity will be evaluated at the time an application is submitted for each PC permit. D. Cumulative Wastewater and Storm Drain System Potential Impact: The proposed Project and the Higher Occupancy Scenario, in conjunction with other pending and future development, could have potentially significant wastewater and storm drainage impacts. (Potentially Significant) Mitigation: The following mitigation measures, as set forth in the FEIR, are hereby adopted and will be implemented as provided in the Mitigation Monitoring Program:
