Implementation of the proposed project would not adversely affect the functionality or capacity of the existing water supply system. (Less Than Significant Impact) 4.17.2.2 Sanitary Sewer/Wastewater Treatment Impacts Operation of the proposed project would result in the generation of approximately 2,763 gpd of wastewater,which is a net increase of 2,639 gpd compared to the existing land use. This increase represents less than one-tenth of one percent of the total wastewater generated in the City. Redwood City has a Capital Improvement Program(CIP) developed for the wastewater system. Every year wastewater proj ects are reviewed,prioritized and implemented to provide sufficient facilities and system capacity to serve the City. Improvement projects ranging from rehabilitation of existing pump stations and replacement of aging sewer infrastructure are completed yearly. In August 2008, Redwood City completed an evaluation of the sewer capacity analysis that provided a list of improvements that are necessary to support future planned growth through the year 2030.44 The proj ect is a part of the residential growth anticipated for Redwood City which will be served by the improvements identified in the City's CIP. Therefore,implementation of the project would not adversely affect the functionality or capacity of the sanitary sewer or wastewater treatment facilities. As a condition of approval,the project will be required to pay a fair share mitigation fee toward the CIP. (Less Than Significant Impact) 4.17.2.3 Storm Drainage The existing site is 61 percent impervious. The existing storm drainage system has sufficient capacity to support the current land use. The project would increase impervious surfaces at the site by 13 percent which would decrease on-site filtration and increase the amount of water entering the storm drainage system. While the project will result in an increase in stormwater runoff,the runoff will be diverted through bioswales which are designed to filter pollutants as well as allow for infiltration into the ground. Pursuant to the regulations of the RWQCB,the bioswales must be numerically sized to allow of infiltration equal to pre-project conditions. Therefore,with implementation of the proposed stormwater control plan,the storm drainage system will have sufficient capacity to accommodate the proposed project. (Less Than Significant Impact) 4.17.2.4 Solid Waste Impacts The project would generate approximately 387 pounds of solid waste per day45 which is 361 pounds per day more than the existing jewelry store use. As stated in Section 4.17.1.4,the California Integrated Waste Management Board(CIWMB)has determined that the Ox Mountain Landfill has a remaining capacity of at least 31 million cubic yards or 80 percent of the landfill's total potential capacity.46 The project would increase solid waste generation from the project site but would be �The improvements listed in the CIP are not part of the proposed project and would be analyzed under a separate environmental review process. 4s Based on the assumed residential solid waste generation rate used in the General Plan EIR of 8.6 pounds of solid waste per dwelling unit per day which is a conservative estimate since these would be smaller units will fewer people per unit. �California lntegrated Waste Management Board. 20ll. <http://www.calrec cl�gov/a�rofiles/Facility/LandfilULFI'rofileIl.as�?Ct7II�=4Il&FACII�=4Il-AA-0002> Accessed September 12,2012.
