This is a drawing exhibit for the California Department of Corrections and Rehabilitation (CDCR) related to repair and stabilization services for solid waste disposal areas at the California Correctional Institution in Tehachapi, California. The project involves stabilization work across four disposal areas: the Main Landfill Disposal Area (786,000 square feet or 18.0 acres), the Construction and Demolition Disposal Area (191,000 square feet or 4.38 acres), the Auto Parts Disposal Area (122,000 square feet or 2.80 acres), and the Burn Ash Area (45,000 square feet or 1.0 acre), for a combined total of 1,099,000 square feet or 25.2 acres of disposal areas within an inspection area of 2,011,000 square feet or 46.2 acres. The scope of work includes clear and grub operations; installation of geotextiles (6 ounces per square yard for swales and 10 ounces per square yard for exposed waste areas); placement of six-inch layers of one-to-one-and-a-half-inch clean crushed gravel; repair of drainage channels on main roads and dirt roads; and installation of rip rap at a culvert entrance. Estimated quantities include approximately 1,449 cubic yards of clean crushed gravel importation and repairs, 77,950 square feet of geotextile fabric, 950 linear feet of main road channel repair, 1,450 linear feet of dirt road channel repair, and 1,470 linear feet of burn ash disposal area channel repair.

The site construction drawings identify topographic survey data compiled from photography dated May 17, 2002, by Inland Aerial Surveys Inc., with horizontal and vertical control assumed to be local. The project drawings were prepared by Inland Aerial Surveys (IAS) for CDCR and show elevation contours ranging from approximately 3,890 feet to 4,650 feet across the facility. Construction details specify that contractors must repair any rutting observed in dirt roads, conduct repairs to exposed waste areas by placing six-to-ten-inch layers of clean crushed gravel over geotextile, repair all disturbed ground with minimum six-inch layers of crushed gravel, and provide topographic survey mapping within a 100-foot offset from the estimated limit of waste upon project completion to document all repairs performed. The drawings contain three pages of site maps, general notes, construction notes, and engineer's estimated quantities necessary for bid preparation and project execution.
