<br />The City of Santa Ana does not contain any impaired water <br />bodies, as defined by Section 303 of the Clean Water Act. <br />However, the City does contain several drainage facilities that <br />convey surface water runoff into bodies of water that are <br />classified as impaired. <br /> <br />Approval of the proposed amendment to the Municipal Code to <br />establish an ordinance for the regulation of Big Box retail uses <br />would not directly involve routine waste discharges that would <br />be in conflict with water quality standards established by the <br />State Regional Water Quality Control Board, in that the approval <br />of the proposed ordinance would not involve any long term <br />operations or construction activities that would involve the <br />discharge of water. Through the conditional use permit process, <br />future Big Box retail uses implemented under the proposed <br />ordinance would be evaluated for potential water quality impacts <br />and would be subject to the City's storm water protection <br />requirements. <br /> <br />B. Substantially deplete groundwater supplies or interfere <br />substantially with groundwater recharge such that there <br />would be a net deficit in aquifer volume or a lowering of <br />the local groundwater table level. <br /> <br />Q. Have a potentially significant adverse impact on <br />groundwater quality? <br /> <br />No Impact <br /> <br />The City of Santa Ana receives 66% of its water from underground <br />water supplies. The underground water basin in the City ranges <br />from -50-feet to +40-feet above sea level. Presently, the City <br />pumps underground water from 21 water wells. Fourteen of the <br />water wells pump ground water into small surface reservoirs. The <br />remaining seven water wells pump underground water into the <br />City's distribution system. <br /> <br />Approval of the proposed amendment to the Municipal Code to <br />establish an ordinance for the regulation of Big Box retail uses <br />would not result in adverse impacts to underground water <br />supplies or prevent the recharge of underground water supplies, <br />in that approval of the proposed ordinance would not involve any <br />activities that would impact underground water supplies or <br />provide impervious surfaces that would prevent the recharge of <br />underground water supplies. Additionally, Big Box retail uses <br /> <br />7~~7 <br />
