We interpreted the medium dense <br /> 1 brown sand to be weathered native soils. Underlying this material,the soil boring encountered medium <br /> dense, brown to gray sand with silt to the depth explored of approximately 11.5 feet below the ground <br /> surface. We interpreted this material to be recessional outwash. <br /> Soil boring B-6 was located near 4414 Ridgemont Drive. The soil boring encountered about 3 inches of <br /> asphalt pavement at the surface. Below the asphalt pavement, the soil boring encountered very loose, <br /> brown sand with silt to a depth of about 4.5 feet below grade. We interpreted the very loose soils to be <br /> undocumented fill. Below the fill material,the soil boring encountered loose,brown sand with silt to a <br /> depth of about 7.0 feet below the ground surface. We interpreted this material to be weathered native <br /> soils. Underlying weathered soils, the soil boring encountered medium dense, brown to gray sand with <br /> silt to the depth explored of approximately 11.5 feet below the ground surface. We interpreted the <br /> medium dense sand with silt to be recessional outwash?. <br /> Soil boring B-7 was located near 912 Wetmore Avenue. The soil boring encountered about 4 inches of <br /> asphalt pavement at the road surface. Underlying the asphalt pavement, the soil boring encountered <br /> very loose, brown silty sand with gravel to a depth of about 4.5 feet below grade. We interpreted the <br /> very loose soils to be undocumented fill. Below the fill material, the soil boring encountered medium <br /> dense/very stiff, brown to gray, silty sand interbedded with silty clay to a depth of approximately 9.5 <br /> feet below the surface. We interpreted the medium dense/very stiff soils to be recessional outwash. <br /> Underlying this material, the soil boring encountered dense, brown to gray, silty sand with clay to the <br /> depth explored of approximately 11.5 feet below grade. We interpreted the dense soils to be glacial <br /> Idrift. <br /> Soil boring B-8 was located near 816 Wetmore Avenue. The soil boring encountered about 6 inches of <br /> asphalt pavement at the ground surface. Underlying the asphalt pavement, the soil boring encountered <br /> loose to medium dense, brown silty sand with trace gravel to a depth of about 1.5 feet below grade. We <br /> interpreted this material to be undocumented fill. Below the fill material, the soil boring encountered <br /> stiff to very stiff, gray to brown sandy silt to the depth explored of about 11.5 feet below the ground <br /> surface. We interpreted the sandy silt to be recessional lacustrine deposits. <br /> Soil boring B-9 was located near 716 Wetmore Avenue. The soil boring encountered about 5 inches of <br /> asphalt pavement at the road surface. Underlying the asphalt pavement, the soil boring encountered <br /> loose to medium dense, brown silty sand with gravel and cobbles to a depth of approximately 4.5 feet <br /> below grade. We interpreted this material to be undocumented fill. Below the fill material, the soil <br /> boring encountered medium dense, gray to brown silty sand with clay to a depth of about 7.0 feet below <br /> the ground surface. We interpreted the medium dense soil to be recessional outwash. Underlying this <br /> material,the soil boring encountered stiff to very stiff, gray sandy silt with clay to the depth explored of <br /> Krazan&Associates,Inc. <br /> Offices Serving The Western United States <br /> I <br />
