7.B. - Page 104 2 Environmental Analysis 2.17 UTILITIES AND SERVICE SYSTEMS Appendix K contains the Utilities and Service Systems Report that describes the existing utilities within the project area and evaluates the potential project impacts to utility systems including wastewater, stormwater treatment,water supply, and solid waste facilities. The project area would be located within a developed area that contains wastewater,water supply, and solid waste systems. Section 2.10,Hydrology and Water Quality, discusses the existing stormwater drainage facilities within the project area in more detail. The City's 2005 Capital Improvement Program (CIP) objective is intended for replacing existing storm drain pipes with new polyvinyl chloride (PVC) pipes,ductile iron pipes (DIP), or reinforced concrete pipes (RCP) to accommodate current discharge rates from stormwater runoff and storm events (City of Redwood City,2011). The local wastewater systems in the project area are owned and operated by the City,which has a joint powers authority ownership with the South Bayside System Authority (SBSA). The SBSA operates a wastewater treatment plant near Radio Road on the eastern part of Redwood Shores. The SBSA has a current operating capacity of 29 million gallons per day (mgd) average dry weather flow (ADWF) and a peak wet weather flow (PWWF) of 71 mgd to discharge to the San Francisco Bay (City of Redwood City,2010). The SBSA has an existing 48-inch sewer force main that runs along the east side of US-101 freeway and would be directly adjacent to the proposed project facilities (City of Redwood City,2011). The City's potable water supply is provided by the San Francisco Public Utilities Commission (SFPUC) through the Hetch Hetchy regional water system (City of Redwood City,2011 The South Bayside Waste Management Authority (SBWMA) has a joint powers agreement (JPA) with the City for managing solid waste generated in the City. The Ox Mountain Landfill is the primary landfill to which solid waste in the City is transported to and disposed of. The landfill currently has 80 percent (31 million cubic yards of space) left and is permitted to operate through 2018 (City of Redwood City,2010). AT&T, Comcast,and Astound provide cable services in the City; Pacific Gas and Electric (PG&E) provides electric and gas services for the City. AT&T conduits run under the US 101 freeway where the proposed joint-use path would be located. Additionally, PG&E has two 25-kV lines in an underground utility trench that cross under the highway where the proposed joint-use path would go. Both of these utilities would be relocated to a deeper elevation underneath the proposed joint-use path to minimize the disruption of any cable or electricity services prior to project construction. This would minimize the impact to existing cable,gas,and electric utility services in the area to a less than significant level. 2-64 US 101 Pedestrian Undercrossing and Bair Island Road Storm Drain Pump Station Project
