Surface mining permits are issued and administered by Alameda County to regulate surface mining operations, to ensure that adverse environmental impacts are minimized, and mined lands are reclaimed to a usable condition. In 1981, Alameda County adopted a specific plan for the quarry areas between Pleasanton and Livermore to function as a master reclamation plan to address (and mitigate impacts of) mining operations within the area designated for quarry use by the Alameda County General Plan. PGC has submitted various applications for SMPs to Alameda County for the three parcels in question in recent years; however Alameda County staff has indicated that these applications have been withdrawn, subsequently resubmitted, and then on occasion been put on hold by PGC pending negotiations with the likely mining operator, Vulcan Materials. Alameda County staff indicates there is currently no approval for mining on any of the three sites.10 Traffic Engineering Pleasanton Traffic Engineering staff has provided an initial evaluation of potential traffic impacts from an industrial park -type development on the three sites. Based on this preliminary assessment, from a Traffic Engineering perspective, industrial development as contemplated by the City of Livermore will add several hundred peak hour trips to and from 1-580. The intersection of Stoneridge Drive and EI Charro Road has three southbound left turn lanes and two westbound right turn lanes, and these lane geometries appear to be adequate to handle the increased traffic volume. It is anticipated that the Interstate -580 interchange at EI Charro Road will be widened in the next 5-10 years; the City of Pleasanton would like to see how any project -related traffic impacts this interchange as well as on other critical City of Pleasanton roads and intersections. The City would request a comprehensive traffic study be completed, including the development of these parcels and other cumulative projects in the vicinity (in Pleasanton, Livermore and Dublin) to determine what traffic impacts may result and how they should be mitigated. The City of Livermore's long-range circulation plans in this area include capacity improvements on Jack London Boulevard (increasing the road from its existing two -lanes to four lanes, as well as eliminating the existing "s - curve" on Jack London north of SMP 39); the City of Pleasanton would request that these improvements be advanced as the three sites are developed. 10 The land on which SMPs are approved have underlying zoning designations of Water Management and Large Parcel Agriculture under the Alameda County East County Area Plan. Subject to the provisions of Measure D, the Water Management land use designation provides for sand and gravel quarries, reclaimed quarry lakes, watershed lands, arroyos, and similar and compatible uses. The Large Parcel Agriculture designation provides for agricultural uses, agricultural processing facilities, limited agricultural support service uses, secondary residential units, visitor -serving commercial facilities, recreational uses, public and quasi - public uses, solid waste landfills and related waste management facilities, quarries, wind farms and related facilities, and utility corridors. Therefore, presumably, the Industrial land use designation in Alameda County East County Area Plan would need to be modified for a SMP to be approved for the subject properties. Page 7 of 10
