Environmental Checklist <br />CEQA Compliance <br />operated near capacity without a third standby pump. The lack of redundancies is <br />particularly an issue because trash and rags frequently enter the pump and render them <br />inoperable. Additionally, ventilation in the dry pit of the existing lift station is inadequate, and <br />the dry pit access is prone to flooding during rain events which requires the City to maintain <br />sand bags around the access cover from November to February each year. Furthermore, <br />the access to the dry pit is located in the middle of a pedestrian sidewalk which must be <br />closed for extended periods of time during entry. In addition, the pumps, motors, and other <br />equipment have exceeded their design life. <br />The existing lift station within Bristol Street is composed of a packaged station measuring <br />12 feet in diameter and 10 feet in height, with an entry tube measuring approximately four <br />feet in diameter. Demolition of the existing lift station would involve the abandonment in <br />place of the existing lift station, which would include removal and disposal of all pumps, <br />suction, and discharge piping, valves, fittings, control panels, conduits, wiring, <br />miscellaneous piping, exhaust fans, duct piping and ladder. The lift station would then be <br />filled with sand. Demolition also would require the abandonment in place of the existing <br />four-foot diameter by 20-foot deep wet well manhole, which also would be filled with sand. <br />The upper 15 inches of the existing 8-foot diameter by 16-foot deep wet well also would be <br />removed and filled with sand. An existing generator, located southerly of the existing lift <br />station, would remain in place and would serve as a back-up power source for the proposed <br />lift station. Finally, some removal and replacement of existing sidewalk and roadway <br />pavement would occur in association with proposed demolition activities. Please refer to <br />Figure 4, Existing Lift Station Demolition Plan, for a graphical depiction of the proposed <br />demolition activities. <br />The proposed facility would be constructed at the western end of San Lorenzo Avenue, <br />immediately north of Segerstrom Avenue and south of an existing alley. As part of the <br />construction of this proposed facility, some demolition activities would occur, as depicted in <br />Figure 5, Proposed Lift Station Demolition Plan. Demolition activities would include the <br />removal and disposal of existing pavement, curb, and gutter (both within the existing alley, <br />the western end of San Lorenzo Avenue, and the northern edge of Segerstrom Avenue); <br />the removal of existing trees and landscaping; the removal of an existing six-foot tall block <br />wall; and the removal of an existing power pole. During construction activities a temporary <br />construction easement is proposed to be located within an adjacent parcel (APN No. 410- <br />411-19) comprising approximately 900 s.f. in size. Figure 6, Temporary Construction <br />Easement, depicts and describes the area proposed for the temporary construction <br />easement. The temporary construction easement is necessary to allow for the removal of <br />the existing solid block wall and to facilitate the construction of a new wall along with backfill <br />and removal of shoring. Additionally, during construction of the proposed project the driveway <br />of the property located at 2909 Bristol Street (Studio Inn) will be impacted periodically, but the <br />access to the property will be maintained at all times and the construction of the driveway will be <br />done one half at a time. Driveways along Segerstrom Avenue as well as the main entrance to <br />the site from Bristol Street will not be impacted. <br />Figure 7, Proposed Lift Station Site Plan, depicts the physical improvements proposed as <br />part of the project. As shown, the project would require the repaving of a portion of the <br />western end of San Lorenzo Avenue, portions of the existing alley, and a portion of <br />Page 4 of 64 <br />75E-8 <br />
