8.A. - Page 102 Section 4: Evaluation of Environmental Impacts the existing treatment plants. Furthermore, residential development is not subject to point- source discharge requirements. The project will not impact compliance with RWQCB treatment requirements. Future housing development will not interfere with compliance with RWQCB wastewater treatment requirements. The proposed Housing Element does not change any applicable land use designations and does not propose or anticipate any specific development proposals. Thus, no impact will occur. b) Less than Significant Impact. The Housing Element is a General Plan policy document that addresses housing need in the City; no actual development or rezoning /re- designation of land is proposed as part of the Housing Element. As such, adoption of the Housing Element, by itself, would not generate water or wastewater. Future development constructed pursuant to General Plan and Housing Element policy will incrementally increase water demand and wastewater discharges. Wastewater treatment for Redwood City is provided by the SBSA treatment plant, located at the northeastern end of the Redwood Shores peninsula. SBSA operates under a joint powers authority (JPA) with four member agencies: the cities of Redwood City, Belmont, and San Carlos, and the West Bay Sanitation District (serving Menlo Park, Atherton, Portola Valley, and parts of East Palo Alto and San Mateo County). The City Public Works Department is responsible for operation and maintenance of the sanitary sewer collection system serving Redwood City. The system consists of approximately 280 miles of sewer mains, along with 31 sewer lift stations. Improvements to the wastewater collection pipelines are ongoing, with continual updates and replacements to the existing system. The SBSA treatment plant has an operating capacity of 29 million gallons per day (mgd) average dry weather flow (ADWF). The plant is permitted by the RWQCB to discharge 29 mgd ADWF into San Francisco Bay. The current permitted peak wet weather capacity of the SBSA facility is 71 mgd. Redwood City has been allocated about 13.8 mgd of average dry weather capacity at the SBSA treatment facility. Based on the per capita wastewater generation rate of 70 gpd assumed for the 2008 SBSA flow study, the total estimated average dry weather flow for the City in 2030 will be 8.17 mgd, which is well below the City's allocation of 13.8 mgd. To ensure that both existing and future water system infrastructure needs are met, General Plan Program BE- 134 calls for the preparation of a Water Master Plan that will include recommendations to ensure the long term viability of the system in light of any anticipated capacity changes, as well as to ensure reliability of the system during seismic events. According to the City, the Water Master Plan will include a capital improvement program as well as an integrated seismic improvement program. Further, Policy NR -3.1 requires new development to fund its fair -share costs associated with the provision of water service, which will help ensure that adequate funding is available to implement the capital improvement program. As the need for new or upgraded water infrastructure is identified through the Water Master Plan and CIP, those projects will undergo their own environmental review at the time they are authorized for design and construction. With the General Plan programs implemented, the proposed Housing Element will not require or result in the construction of new water or wastewater treatment facilities or expansion of existing facilities. Impacts will be less than significant. General Plan Building Environment Element Programs Program BE -134 Water Master Plan. Consider completing a Water Master Plan that includes recommendations to improve water distribution capacity and utilize water demand assumptions from future UWMPs and the General Plan.
