Environmental Checklist For CEQA Compliance Act. However, the city does contain several drainage facilities that convey surface water runoff into bodies of water that are classified as impaired. The proposed SEZ does not propose any specific construction, renovation, or demolition projects. Any future development occurring as an indirect result of the SEZ would be required to go through the City's development review process, and would be evaluated for potential impacts to water quality under CEQA. Where needed, mitigation measures using the above referenced regulations would be required to avoid or minimize potential water quality impacts caused by any individual project occurring as an indirect result of the proposed SEZ. Therefore, impacts of the proposed SEZ to water quality are considered less than significant. B. Less-Than-Significant Impact. The SEZ .does not propose any specific construction, renovation, or demolition projects, yet potential groundwater impacts could occur from development as an indirect result of the SEZ business incentives. Therefore, any future development occurring as an indirect result of the SEZ would be required to go through the City's development review process, and would be evaluated for its potential impacts to groundwater supplies or groundwater recharge. Currently, the city receives 64% of its water from groundwater wells; this percentage is regulated by the Orange County Water District's allowable basin pumping percentage (City of Santa Ana 2005:2-3). This amount can be adjusted as needed based on groundwater basin hydrologic conditions (City of Santa Ana 2005:2-4). Therefore, the potential of the SEZ to indirectly result in activities that would substantially deplete groundwater supplies or interfere substantially with groundwater recharge is considered to be less than significant. C. Less-Than-Significant Impact. The proposed SEZ covers an area of existing intense urban development. Runoff from existing and future developed areas would continue to be conveyed via manmade drainage s#ructures, and ultimately drain to the Santa Ana River and the Pacific Ocean. Any future development occurring as an indirect result of the proposed SEZ financial incentives would be required to go through the City's development review process. Any future individual project would be evaluated for any increase in the rate and flow of water runoff and/or increase in polluted runoff under CEQA. Where needed, mitigation measures would be required to avoid or minimize potential impacts caused by any individual project occurring as an indirect result of the proposed SEZ at the time of the project's review. Therefore, impacts of the proposed SEZ to water quality are considered less than significant. D. Less-Than-Significant Impact. The proposed SEZ covers an area of intense urban development. Runoff from developed areas would continue to be conveyed via manmade drainage structures, ultimately draining to the Santa Ana River. Given the intense existing urban development within the proposed SEZ, it is not likely that the proposed SEZ designation would substantially alter drainage patterns or cause substantial offsite erosion due to induced development and growth as a result of SEZ business incentives. Furthermore, any future individual project indirectly resulting from the proposed SEZ financial incentives would be evaluated under CEQA during the City's development and review process. At this time impacts would be evaluated related to changes in drainage and erosion and mitigation measures would be proposed. Thus, the proposed SEZ would have less-than- significant impacts. E. Less-Than-Significant Impact. The entire proposed project area is within the City of Santa Ana. It is located within the 100-year floodplain and the 500-year floodplain (City of Santa Santa Ana State Enterprise Zone November 2007 Initial Study 3-24 J8S 00814.07 19E-38
