Responses to Environmental Checklist For CEQA Compliance b. ite design Best Management Practices P c. Applicable Routine Source Control BMP Selecting and sizing the Treatment Control BMP e. Mechanisms by which funding for long-term operation and maintenance of all structural BMP will be provided Operation and Maintenance Plan to describe the long-term operation and maintenance requirements of all applicable structural BMP and to identify the entity in charge of implementation • The proposed project would be subject to City of Santa Ana Federal Clean Water Protection Enterprise Fees. 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 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? Less than Significant 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 would just replace similar materials. F. Place housing within a 100-year floodplain, as mapped on a federal Flood Hazard Boundary or Flood Insurance Rate Map or other flood hazard delineation map? G. Place within a 100-year floodplain structures which would impede or redirect flood flows? H. Place housing within a 100-year floodplain, as mapped on a federal Flood Hazard Boundary or Flood Insurance Rate Map or other flood hazard delineation map? No Impact 7~~~~49 9
