Because the preliminary design study in this EIR cannot be considered conclusive in terms of specific roadway reconstruction requirements , it is recommended that the applicant initiate a detailed design study to determine the eventual roadway improvements needed on Davis Road and Ray Road - hile Road prior C32 to final map approval . It does not appear that Peltier would be measurably affected. " ( Page 4 . 2-19 , draft EIR ) . The issuance of the quarry excavation permit will be contingent ,,-- upon compliance with conditions of approval imposed by the County. While it is not uncommon for the County to address the maintenance and restoration of the haul roads in their conditions of approval , it has been our experience that detailed design studies historically have not been required . The nature and scope of any such studies related to the haul roads , would be more appropriately addressed by the County' s Public Works Department in the conditions of approval for the quarry excavation permit . Water Resources The water balance calculations show the make-up wat.?r requirement . to be in the range of 200 to 400 acre-feet during the late summer and early fall of these dry years . In order to meet the water needs of the project , as presently planned , this water would be obtained either from groundwater pumping , from summer diversions from the Mokelumne River under riparian. right ( see following discussion ) , or from a combination of these two sources . . . . . . If obtained from groundwater , it would be equal to twice to three times the present amount of groundwater withdrawal , and would exceed the estimated local recharge of the aquifer , adding to the existing overdraft conditions in the area. " ( Page 4 . 6-12 , draft C33 EIn ) The expansion and year-round maintenance of the Tracy Lakes , along with the increased use of water for irrigation ( golf course and pasture ) and domestic water supply will result in a net loss of cater to tiie local surface and ground»ester system in comparison with existing conditions . The main losses :ill be from lake evaporation and evapotranspiration from turf and other irrigate areas . " ( Page 3-3 , draft EIR ) . The existing groundwater resources in San Joaquin County are in a state of overdraft . Project plans to pump groundwater for lake water level maintenance and irrigation will further add to the overdraft conditions . This could affect groundwater levels locally to the detriment of other water users in the area. " ( Page 5-4 , draft EIR ) . The draft EIR does not make mention of the fact that during normal and wet years , the proposed project will result in a net recharging of the groundwater aquifers . Table 4 . 6-3 of the draft EIR presents the water balance for the project during normal , or average rears and indicates that approximately 103 acre-feet of water per year will be lost to seepage . The large majority of this seepage would contribute III�i6
