Responses to Environmental Checklist For CEQA Compliance 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. No impacts would occur C. Substantially alter the existing drainage pattern of the site or area, including through the alteration of the course of stream or river, in a manner which would result in substantial erosion or siltation on or off-site? D. 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? Less Than Significant Impact The project site is generally flat and located in an urbanized area currently served by an existing storm drain system. The proposed project will not alter the existing drainage pattern of the site and will connect to the storm drain system as required by the City regulations. As previously noted, erosion or siltation could occur during construction related earthmoving activities. The project would be required to comply with the requirements of the NPDES General Construction permit and project approved SWPPP. During the site grading and construction short-term runoff impacts would be addressed through the incorporation of construction erosion and sediment control and flooding BMPs. Compliance with the permit requirements, the project's construction-related impacts of erosion and/or flooding would less than significant. 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? No Impact The City of Santa Ana is a participant in the National Flood Insurance Program (NFIP). Communities participating in the NFIP must adopt and enforce minimum floodplain management standards, including identification of flood hazards and flood risks. Participation in the NFIP allows communities to purchase low cost insurance protection against losses from flooding. The published Flood Insurance Rate Maps (FIRM) for the project site is included on Community Panel No. 06002320256H. The project site is located entirely in Zone X, which is defined as areas beyond the limits of the 100-year flood and 500-year flood. The project site protected from the 1 percent annual chance flood by a levee constructed above the natural bank of the Santa Ana River to the east of the project site. Since the implementation of the proposed project would not place housing within a mapped flood hazard area, there would be no impact. IX. Land Use and Planning A. Physically divide an established community? C. Conflict with any applicable habitat conservation plan or natural community plan? 75A-47
