Site Drainage <br /> All disturbed surface runoff would either be directed to silt ponds or contained within the mining <br /> excavations. No separate dedicated storm water retention ponds are proposed. <br /> The overall mining would be self-contained, meaning that surface drainage would be directed to the open <br /> pits. As mining commences at the site, all storm water drainage would be directed to the operating pits. <br /> Water would be directed to the operating pits through a series of berms, ditches, pipes, and regrading to <br /> prevent erosion and sedimentation. Upon final reclamation, site drainage would drain towards the <br /> northeast and southeast corners where it would first pond in two separate sumps, then percolate into the <br /> ground. <br /> Plant Construction <br /> The plant construction will commence once the site preparation and grading of the plant site has been <br /> completed. The stationary plant will be constructed in the Phase IX area. The general plant layout is <br /> depicted in Figure 3-5. The general components of the aggregate plant include: <br /> Primary crushing and screening tower <br /> • Surge pile <br /> • Three secondary and tertiary crushing and screening towers <br /> • Wet side washing and screening tower <br /> • Product stockpiles <br /> Drive under product load-out tower <br /> • Radial stacker conveyor <br /> • Conveyors <br /> At its highest point, the aggregate plant will be 65 feet tall. The height limit for the agricultural zone is 35 <br /> feet for dwellings and buildings that are accessory to dwellings. However, "other structures" have no <br /> height limit. (Development Title, Table 9-610.2). <br /> Construction of Ancillary Uses <br /> Ready-Mix Concrete Plant <br /> A ready-mix concrete batch plant will be constructed within the Phase IX area to the northwest of the <br /> aggregate plant. Figure 3-5 depicts the location of the batch plant. The concrete batch plant, with an <br /> estimated production of 350,000 cubic yards per year, would have an office measuring approximately 500 <br /> square feet in size. The major components of the batch plant include: <br /> • Cement silos <br /> • Aggregate bins <br /> • Conveyors <br /> • Baghouse <br /> • Bermed admixture tank farm <br /> • Concrete reclaimer <br /> • Concrete-lined washout basins <br /> San Joaquin County QX-01-2\Lonestar California <br /> Community Development Page 5 <br />
