a) Would the project violate any water quality standards or waste discharge requirements? (No • Substantial Change from Previous Analysis) A Preliminary Hydrology Study of Existing and Proposed Conditions and a Water Quality Manage- ment Plan were prepared for the MacArthur Place South project. The EIR identified impacts to hydrology and water quality that would result from project implementation. Recommendations from the technical studies for hydrology and water quality will continue to be observed. No changes have occurred in this area from the analysis provided in the EIR. Therefore, the EIR remains adequate and complete for this topic. b) Would the project substantially deplete groundwater supplies or interfere substantially with groundwater recharge? (No Substantial Change from Previous Analysis) No changes have occurred in this area from the analysis provided in the EIR. Therefore, the EIR remains adequate and complete for this topic. c) Would the project substantially alter the existing drainage pattern of the site or area, including through the alteration of the course of a stream or river, in a manner which would result in substantial erosion or siltation on or off site? (No Substantial Change from Previous Analysis) The EIR identified impacts to the existing and proposed drainage for the proposed project and described the requirements to mitigate impacts to hydrology and water quality. No changes have occurred in this area from the analysis provided in the EIR. Therefore, the EIR remains adequate and complete for this topic. d) Would the project substantially alter the existing drainage pattern of the site or area, including through the alteration of the course of a stream or river, or substantially increase the rate or amount of surface runoff in a manner which would result in flooding on- or off-site? (No Substantial Change • from Previous Analysis) The EIR identified impacts to hydrology and water quality that would result from project implementa- tion. No changes have occurred in this area from the analysis provided in the EIR. Therefore, the EIR remains adequate and complete for this topic. e) Would the project create or contribute runoff water which would exceed the capacity of existing or planned stormwater drainage systems or provide substantial additional sources of polluted runoff? (No Substantial Change from Previous Analysis) The EIR identified impacts due to runoff that would result from project implementation. No changes have occurred in this area from the analysis provided in the EIR. Therefore, the EIR remains adequate and complete for this topic. ~ Would the project otherwise substantially degrade water quality? (No Substantial Change from Previous Analysis) The EIR addressed potential impacts to water quality and included mitigation measures to reduce impacts. Mitigation Measures HW-1 through HW-11 included in the EIR are incorporated herein by reference and will be implemented to reduce impacts. No changes have occurred in this area from the analysis provided in the EIR. Therefore, the EIR remains adequate and complete for this topic. ~ Would the project place housing within a 100 year flood hazard area as mapped on a federal Flood Hazard Boundary or Flood Insurance Rate Map or other flood hazard delineation map? (No Substantial Change from Previous Analysis) The EIR identified impacts to hydrology and water quality that would result from project implementa- • tion. The project is not located in a 100-year flood hazard area. No changes have occurred in this area Resolution No. 2009-025 Page 37 of 95 MacArthur Place South EIR Addendum 39
