Compliance requires filing a <br />Notice of Intent (NOI), a Risk Assessment, a Site Map, a Stormwater Pollution Prevention <br />Plan (SWPPP) and associated best management practices (BMPs), an annual fee, and a <br />signed certification statement. <br />RR HYD-4: All development pursuant to the General Plan Update shall comply with the <br />requirements of the Orange County MS4 Permit (Order R8-2009-0030, NPDES No. <br />CAS618030, as amended by Order No. R8-2010-0062). The MS4 Permit requires new <br />development and redevelopment projects to: <br />• Control contaminants into storm drain systems <br />• Educate the public about stormwater impacts <br />• Detect and eliminate illicit discharges <br />• Control runoff from construction sites <br />• Implement best management practices and site -specific runoff controls and <br />treatments for new development and redevelopment. <br />Dry Utilities <br />RR U-10: New buildings are required to achieve the current California Building Energy <br />and Efficiency Standards (Title 24, Part 6) and California Green Building Standards Code <br />(CALGreen) (Title 24, Part 11). <br />RR U-11: All new appliances would comply with the 2012 Appliance Efficiency <br />Regulations (Title 20, California Code of Regulations, Sections 1601 through 1608). <br />Explanation of the Rationale: <br />Water <br />The Project would involve the installation of water mains, hydrants, fire sprinklers, and proposed <br />recycled water and irrigation laterals and meters based on City and County input during the design <br />permitting phase. The water infrastructure improvements would comply with the City of Santa Ana <br />Design Guidelines for Water and Sewer Facilities and City of Santa Ana's Construction <br />Standards. Construction impacts associated with the installation of new water mains, fire <br />hydrants, and water connections would be temporary and would primarily involve trenching in <br />order to place the water lines below ground within previously disturbed roadways.
