<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 a zoning ordinance for a Specific District and any <br />subsequent construction according to this zoning document would <br />not result in adverse impacts to underground water supplies or <br />prevent the recharge of underground water supplies, in that <br />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 />would not be permitted in areas where underground water recharge <br />occurs. <br /> <br />C. Substantially alter the existing drainage pattern of the <br />site or area, including through the alteration of the <br />course of stream or river, or substantially increase the <br />rate or amount of surface runoff in a manner, which would <br />result in flooding on or off-site? <br />D. Create or contribute runoff water which would exceed the <br />capacity of existing or planned stor.m water drainage <br />systems or provide substantial additional sources of <br />polluted run-off? <br /> <br />L. Result in increased impervious surfaces and associated runoff? <br /> <br />M. Create a significant adverse environmental impact to drainage <br />patterns due to changes in runoff flow rates or volumes. <br /> <br />No Impact <br /> <br />7"4'59 <br />
