Analysis Project Site History The existing quarry was originally permitted in 1957, and renewed under Excavation Permit EP-75-3. An Environmental Impact Report was prepared in 1975 (EIR-75-6). The permit was for the extraction of 1,500,000 cubic yards of sand and gravel. In 1981 Excavation Permit (EP-81-6) was approved by the Board of Zoning Adjustment for the removal of 500,000 tons of material over a five year period. On September 12, 1989, the Planning Commission approved Quarry Excavation application no. QX-89-0002, with an expiration date of August 31, 2009. On April 14, 1998 the Board of Supervisors approved Development Title Text Amendment TA-98-0001 to allow for the Continuation of an Accessory Use for an existing Quarry Operation if the resources are nearly exhausted or have been exhausted subject to the approval of a Revisions of Approved Actions Application. Pursuant to the approved Development Title Text Amendment, the applicant filed a Revisions of Approved Actions application to modify the Conditions of Approval to permit the continued operation of the authorized accessory uses. On March 4, 1999 the Planning Commission approved this application and the Community Development Department has modified this Staff Report to correctly reflect the permitted Accessory Use(s) once the resources are exhausted. Permitted Accessory Use(s) shall include an asphalt batch plant, storage silos, a sand and gravel processing plant, truck scales, accompanying stockpiles, storage, offices, and shop. On March 4, 1999 the Planning Commission approved a Revisions of Approved Actions application for Quarry Excavation permit no. QX-89-0002 extend the life of the permit 30 years from the original date of approval, with an expiration date of March 4, 2029 and to the excavation and rehabilitation, shall be complete prior to 30 years from the date of approval of the Revisions of Approved Actions. Project Setting Permitted activities for the site consist of processing of aggregate materials (sand and gravel). Aggregate is trucked to the site from source pits, washed, screened and crushed. Additional sand is excavated from the quarry located northeast of the project site and transported via conveyor belts underneath East River Road to the processing facilities. The processed aggregate is either directly hauled to the construction site, or is used for the onsite asphalt concrete hot mix batch plant(AC plant). The site consists of reclaimed areas, reserve areas, wash ponds, production facilities, administrative offices, and access roads. The reclaimed and reserve areas are mostly planted in orchards. The orchards are farmed by independent contractors. The project site is adjacent to the north, south, east and west by agricultural lands (almond and walnut orchards)and scattered residences.
