ftp <br /> the west. This material weathered and was transported downstream to the mouth of the <br /> canyon, where it was deposited forming a radial fan. The dominant rock types found in the <br /> fan are metagreywacke (sandstone), quartz and chert. Minor amounts of ultramafic and <br /> volcanic rock are also present. The gravels of the Corral Hollow Fan range up to 135 ft. in <br /> thickness, thinning and decreasing in coarseness toward the east, away from the mouth of <br /> the canyon. <br /> The property is nearly flat-lying, ranging in elevation from 148 to 138 feet above sea level <br /> and sloping to the northeast. The soils are classified as Sorrento gravelly clay loam derived <br /> from a sedimentary rock source. The property's Storie Index rating is 85 (see Appendix E). <br /> Gravels underlie this soil and are dominant to over 80 feet for most of the site. Clay lenses <br /> from a few feet up to 20 feet thick occur sporadically throughout this deposit. The <br /> groundwater is estimated by John Jones (City of Tracy water treatment plant) to be at a <br /> depth of ±140 feet. <br /> Soil Stability Study <br /> A soil review is underway by Kleinfelder and Associates. Results will be submitted upon <br /> completion. <br /> Landscaping and Fencing <br /> ` Oleander bushes and/or acacia longifolia bushes will be planted at 10-foot intervals along <br /> MacArthur Road. Three-strand barbed wire fencing 4 feet in height will be placed around <br /> r <br /> the site. <br /> Air <br /> Teichert will comply with all San Joaquin County Air Pollution Control District rules and <br /> regulations. Dirt roads used for access to the site or for the transport of material will be <br /> kept moist with water. Water spraying equipment will be available to reduce any dust <br /> generated during the removal of overburden, excavation of aggregate, and loading materials. <br /> The first 100 feet of access road adjoining MacArthur Road will be paved. <br /> 5 M 50464-B <br />
