anf^ Responses to Environmental Checklist For CEQA Compliance R. Cause or contribute to an exceedance of applicable surface or groundwater receiving water quality objectives or degradation of beneficial uses? S. Impact aquatic, wetland or riparian habitat? No Impact The City of Santa Ana is included within four watersheds, San Diego Creek, Santa Ana River, Talbert and Westminster. Each of these watershed areas are under the jurisdiction of the Santa Ana Regional Water Quality Control Board and subject to the objectives, water quality standards and Best Management Practice requirements established in the Santa Ana River Basin Plan and Orange County Drainage Area Management Plan. The City of Santa Ana implements the goals, objectives and requirements of the Basin Plan and Drainage Area Management Plan through the City's Local Implementation Plan. Storm water flows from the project site would be conveyed to an underground storm drain before ultimately discharging into Santa Ana River watershed. The Santa Ana Regional Water Quality Control Board has identified Santa Ana River as impaired by nutrients, sediments, metals and pesticides. Since no new construction is proposed for this project, there will be no impact to the hydrology and water quality from the project. B. Substantially deplete groundwater supplies or interfere substantially with groundwater recharge such that there would be a net deficit in aquifer volume or a lowering of the local groundwater table level. No Impact The proposed project would not interfere with ground water recharge because the project area is not located in an area that is known to recharge the ground water system. Additionally, construction operations for the proposed project are limited to exterior improvements and interior tenant improvements and would not encroach onto the underground water basin. Implementation of the proposed project would not result in significant impacts to any underground water supplies. C. Substantially alter the existing drainage pattern of the site or area, including through the alteration of the course of 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? D. Create or contribute runoff water which would exceed the capacity of existing or planned storm water drainage systems or provide substantial additional sources of polluted run- off? No Impact The project site is located within an urbanized area with improved drainage facilities. The proposed project would not introduce additional impervious surfaces unto the project site. There would be no significant increase in the surface water flows generated from the project site because the site is currently imperious and the project will not change the existing conditions. 75C-100 7
