Climatology The climate is semi-arid with winter and spring rainfall of seven.to ten inches per year. The rainfall is seasonal with low heavy fog in the winter months. Snow in not a factor in annual precipitation. Low temperature in the winter ranges from 20 to 50 degrees Fahrenheit. Summer high temperatures range from 80 to 110 degrees Fahrenheit, with no precipitation- Winter and spring winds may reach 70 MPH on very rare occasions. ; Land Use and General Plan Designations Current land use of the project site is an irrigated orchard which is not in r 9 production at this time and one residence. Irrigation is by the furrow method with water supplied by well. The project site's General Plan designations are AIG (General Agriculture) and OS/RC (Open Space Resource Conservation), and the zone is AG-40 (General Agriculture, 40- acre minimum parcel size). The project site is also within the Mineral Resource Zone (MRZ-2) as designated by the State Mines and Geology Board. i. Aesthetics The proposed project would have structures to 40 feet in height that could be seen from all directions within a five mile radius. Quarry operations are below the surface and would . only be seen from within 50 feet the project boundary. Pursuant to Section 9-1415.3(m) of the San Joaquin County Development Title, proponent shall construct a five-foot berm with mature landscaping (to eight feet in height above the berm) to reduce aesthetic impacts. The berm would surround the property on the side facing Koster Road. Traffic on Koster Road would not therefore see the quarry operation. The aggregate processing plant and asphalt concrete plant would remain visible from Koster Road.- However, visual exposures would be localized and experienced by relatively few viewers. 3.3 PROJECT OBJECTIVES Objectives of Project Proponent DSS Engineering Contractors, the project proponent, proposes to excavate sand and gravel resources from the project site. With the proposed project, the proponent intends to provide a reliable, continuous supply of aggregate products over an approximately 56- year period for the rapidly growing San Joaquin region. Aggregate production would be driven.by market demand, anticipated by the proponent to be approximately 400,000 tons per year for the first seven years and increasing to 550,000 tons per year for the remaining 49 years. Aggregate would be transported from the excavation site to the processing plant by conveyors and scrapers and transported by truck from the processing plant to point of . use.
