Chapter 4 Environmental Setting, Impacts, and Mitigation Measures P. Utilities and Service Systems With respect to drainage, flood control, and non-point source pollution, the Specific Plan commits to the provision of adequate onsite storm water detention capacity and coordina- tion with Zone 7 on stormwater release patterns to meet regional flood control objectives. (1) Water Supply System and Wastewater Collection The Phase I infrastructure systems for potable water supply and wastewater collection are complemented in the Phase II Specific Plan by graphics showing lines that (a) existed in 2000, (b) were constructed in conjunction with Phase I development, and (c) would be built to serve Phase II (see Figures 24 and 25). (2) Surface Water Management As described in Chapter 4 Part H (Hydrology and Water Quality), the Phase II Specific Plan would have the following characteristics with respect to surface water management: . Land uses that provide extensive permeable surfaces in the form of public park land and open space. . Management of storm drainage through provision of onsite stormwater detention facilities incorporated into the landscape. Based on a hydrologiC study49, the stormwater detention facilities were sized to accommodate the full development of the site (both Phase I and Phase II) so that the discharge rate from the basins would not exceed the pre-development rate of discharge for the 1 OO-year storm. It is the intention of the City that all development within the Plan area fully comply with Provision C.3 requirements of the Countywide National Pollutant Discharge Elimina- tion System (NPDES) permit including hydromodification requirements. . Surface and groundwater quality would be protected by designing the potential agri- culture club to channel animal waste to the City's sanitary sewer, or to otherwise manage that waste to avoid its pollution of either surface or groundwater. In addition, the site plan for the Phase II Specific Plan will accommodate a water quality feature (a pond of about one acre in surface area) along the redesigned drainage channel along the eastern edge of the property. This pond would be used for debris/sediment control only, not hydromodification. (3) Solid Waste The Specific Plan includes land uses that will generate a certain amount of solid waste. While no estimates of solid waste generation for the project have been prepared, data assembled by the California Integrated Waste Management Board (CIWMB) can be used to estimate potential levels of solid waste generation. Land used predominantly as lawn (sports fields, turf) generates 7.6 tons of waste per acre per year.so Businesses that include 49 Balance Hydrologic, Inc., November, 2000. 50 Carr, Nancy, California Integrated Waste Management Board, e-mail communication with Mundie & Associ- ates, January 12,2006. 157
