3.0 ENVIRONMENTAL CHECKLIST <br />1388 Bancroft Avenue Project City of San Leandro <br />Initial Study/Mitigated Negative Declaration November 2018 <br />3.0-74 <br />Nevada, with the remaining 10 percent coming from protected watershed lands and reservoirs in the East Bay Hills (San Leandro 2016b). <br />WASTEWATER <br />Wastewater collection and treatment for the project site is provided by the San Leandro Public <br />Works Department, Wastewater Treatment Division. The City operates and maintains the San Leandro Water Pollution Control Plant (WPCP), which serves about 55,000 residents, as well as <br />businesses, in the northern two-thirds of San Leandro. The WPCP is permitted by the San Francisco <br />Bay RWQCB to provide secondary treatment of up to 7.6 million gallons per day (mgd) average <br />daily dry water flow. In 2010, the actual average dry water flow to the plant was 4.9 mgd, leaving 2.7 mgd of unused permitted dry weather flow capacity in 2010 (San Leandro 2016b). <br />STORMWATER <br />The San Leandro Public Works Department owns and maintains 175 miles of storm drain conduits throughout the city. The City’s storm drain system feeds into a larger system owned and operated <br />by the Alameda County Flood Control and Water Conservation District (ACFCD). The ACFCD’s <br />drainage facilities include levees, pump stations, erosion control devices, and culverts. Stormwater <br />on the project site is currently discharged into the City’s municipal storm drain system in the adjacent streets and conveyed to the ACFCD stormwater collection system. <br />SOLID WASTE <br />Alameda County Industries (ACI) has a franchise agreement with the City to provide solid waste and recycling disposal services. In 2014, the California Department of Resources Recycling and <br />Recovery (CalRecycle) reported that 93 percent of the city’s solid waste disposal waste went to <br />a total of four landfills: Altamont Landfill, Forward Sanitary Landfill, Potrero Hills Landfill, and Vasco <br />Road Sanitary Landfill (San Leandro 2016b). <br />CHECKLIST DISCUSSION <br />a, e) Less Than Significant Impact. Wastewater generated by the proposed project would be <br />conveyed through the City’s sanitary sewer system to the Water Pollution Control Plant. The San Francisco Bay RWQCB regulates water quality and quantity of effluent discharged <br />from the City’s Water Pollution Control Plant. The treatment plant is permitted to provide <br />secondary treatment of up to 7.6 mgd, and the actual average dry water flow to the plant <br />in 2010 was 4.9 mgd. Thus, the WPCP had 2.7 mgd of unused permitted dry weather flow capacity in 2010 (San Leandro 2016b). The volume of wastewater generated by the <br />proposed project is estimated to be approximately 6,459 gallons per day (gpd),3 which <br />would be accommodated by the excess treatment capacity at the WPCP. Since the plant <br />has excess capacity and the wastewater generated by the proposed project would represent a minimal addition, the project’s impact would be less than significant. <br />b, d) Less Than Significant Impact. As discussed above in the response to checklist item a), the <br />proposed project would be served by the City’s WPCP, which had 2.7 mgd of unused <br />permitted dry weather flow capacity in 2010 (San Leandro 2016b). The proposed project is estimated to generate about 6,459 gpd of wastewater. As described above for checklist <br /> <br />3 Consistent with the methodology of the General Plan EIR (San Leandro 2016b), the volume of wastewater is estimated to be 80 percent of the project’s water demand, which is calculated in checklist item b, d).
