• Mitigation Measures UT -5.1 and UT -5.2 Finding: Mitigation Measures UT -5.1 and UT -5.2 are feasible and would reduce the impacts of the Project and the Higher Occupancy Scenario related to increased wastewater flows and storm water runoff to less -than- significant levels. The City of Redwood City possesses an option to purchase an additional 2.685 mgd from the Stage II expansion of the South Bayside System Authority's water treatment facility to accommodate wastewater flows from Kaiser and other cumulative development. Currently, approximately 2.08 mgd out of the 2.685 mgd sewer treatment capacity rights are available for purchase. This additional capacity is sufficient to accommodate the projected wastewater flow from the proposed Project or the Higher Occupancy Scenario. However, under the proposed Project and the Higher Occupancy Scenario, development would occur at the Project site over a 20+ -year horizon. Depending on the schedule of construction at the Project site, the remaining reserve capacity could be exhausted, and development and purchase of additional wastewater treatment capacity as part of a Stage III expansion would be necessary. In addition, the local sewer collection system and the South Bayside System Authority's sewer transmission facilities would need to be upgraded. The Storm Drain Sub - basin, in which the Project site is located, is relatively small and serviced by the Maple Street Storm Drain Pump Station and the (K -Mart) Pump Station at Steinberger Creek, as shown in the FEIR. Although the effects of the proposed Project and the Higher Occupancy Scenario on storm water volumes is expected to be less than significant, the storm drains may already be at capacity. Cumulative development may therefore adversely affect the piping system and the pump stations at Maple Street and at Steinberger Creek. The contribution of the proposed Project and the Higher Occupancy Scenario to this cumulative effect is anticipated to be less than significant; this assumption shall be confirmed as Kaiser requests subsequent approvals for phases of the Project. Mitigation Measures UT -5.1 and UT -5.2 would reduce the cumulative impact of the proposed Project or the Higher Occupancy Scenario on wastewater treatment and the storm drain system to a less- than - significant level by providing funding for increased wastewater treatment and the storm drain system capacity. If additional wastewater treatment capacity rights are needed at the South Bayside System Authority's wastewater treatment facility due to the increase of flows from any future phases of the proposed Project or the Higher Occupancy Scenario, Kaiser would provide its fair share of funds for South Bayside System Authority's Stage II, or future stages of expansion of rights. If additional storm drain collection capacity or pump station capacity is needed due to the increase of storm water flows from any future phases of the Master Plan, Kaiser would provide its fair share of funds for improvements to the storm drain facilities.
