Project? Impacts? Impacts? Verification? Impacts? With implementation of the mitigation measures listed in the IS/MND, implementation of the Proposed Project would not result in any residual significant impacts related to increased risk of flooding from stormwater runoff, from water quality effects from long-term urban runoff, or from short-term alteration of drainages and associated surface water quality and sedimentation. Based on these circumstances,the Proposed Project would not result in any residual significant and unavoidable adverse impacts to surface water hydrology and water quality. IS/MND Mitigation Measures: • Mitigation Measure HWQ-l: Implement Construction Best Management Practices • Mitigation Measure HWQ-2: Avoid Cutting Through Creeks • Mitigation Measure HWQ-3: Implement Best Management Practices • Mitigation Measure HWQ-4: Implement Recycled Water Best Management Practices Project Change Discussion: The proposed changes to the Proposed would have the same impacts to hydrology and water quality than the Original Proposed Project. The addition of 720 feet or 0.1 mile of new pipeline would not result in any new impacts as was evaluated in the IS/MND. Also, the construction activities associated with the revised pipeline conveyance facilities would be substantially the same as they were originally described in the IS/MND as they would also be constructed within existing roadways, highly disturbed areas, and/or public right-of-ways. The Revised Proposed Project therefore would not have any incrementally significant hydrology and water quality effects as defined in CEQA Guideline section 15162(a). Land Use and IS/MND Planning Page 3-29 NI No - No No Yes IS/MND Discussion: The IS/MND concluded that the Proposed Project would not have any adverse or significant effects on land use or land use planning. Specifically,the Proposed Project would not result in a disruption,physical division,or isolation of existing residential or open space areas. The Proposed Project would not conflict with any applicable land use plan,policy,or regulation of an agency with jurisdiction over the Project area. The Proposed Project would also not conflict with the provisions of an adopted Habitat Conservation Plan, Natural Conservation Community Plan, or other approved local,regional,or state habitat conservation plan. As a result,no mitigation is necessary. IS/MND Mitigation Measures: • None identified or necessary. Project Change Discussion: The proposed changes to the Proposed would have the same impacts to land use and land use planning as the Original Proposed Project. The addition of 720 feet or 0.1 mile of new pipeline would not result in any new impacts as was evaluated in the 1S/MND. Also, the construction activities associated with the revised pipeline conveyance facilities would be substantially the same as they were originally described in the IS/MND as they would also be constructed within existing roadways, highly disturbed areas, and/or public right-of-ways. The Revised Proposed Project therefore would not have any incrementally significant land use and land use planning effects as defined in CEQA Guideline section 15162(a). December 2014 3-7
