X <br /> ANALYSIS: Surface Water and Drainage - State and federal government agencies are responsible for <br /> standards for storm water discharge under the authority of the Clean Water Act (33 U.S.C. § 1251 et <br /> seq.). As part of the requirements, all storm drainage that discharges into public waters would be <br /> required to meet water quality standards outlined in new National Pollution Discharge Elimination <br /> System (NPDES) Permit requirements. The project will not affect existing drainage patterns in the <br /> project vicinity. No significant new sources of runoff water would be created by the project that would <br /> exceed the capacity of stormwater drainage systems, nor would new sources of polluted runoff be <br /> created. The storage reservoir and pump station facilities will be designed to accommodate additional <br /> storm runoff generated by impervious surfaces. <br /> The project does not include new housing, and does not change the 100-year flood hazard area. The <br /> project proposes no structures to be placed within a 100-year flood hazard area such that they would <br /> impede or redirect flood flows. The project contains no elements that would expose people or <br /> structures to a significant risk of loss, injury or death involving flooding. The potential exists for recycled <br /> water to contact surface water bodies in one of two ways: 1) application rates to irrigated areas which <br /> are too high, and 2) mixing with stormwater runoff. Because of the high quality of the recycled water <br /> that is produced, surface runoff would not be detrimental to existing surface water quality of adjacent <br /> streams and sloughs. However, recycled water may contain sufficient nutrients to promote algae <br /> growth, so excessive runoff to surface water bodies should be avoided. Recycled water is generally not <br /> used for irrigation during wet weather, when there is higher potential for surface runoff to neighboring <br /> creeks and sloughs. In addition, based on operation reports for the First Step Recycled Water Project, <br /> application rates are monitored by users during dry weather so that surface runoff due to excessive <br /> irrigation is avoided. The City will continue to conduct periodic inspections to ensure that these <br /> conditions are observed. <br /> 20 <br />
