CITY OF SANTA ANA <br />Planning and Building Agency <br />St. Barbara Catholic School <br />Project No.: D-6289-01 <br />Soils Condition <br />Soils under the project area consisted of minor fill at the top followed <br />Approved <br />FOR PERMIT ISSUANCE <br />consisting of sand, silty sand, sand with some silt and clay, light brown to gray, coarse <br />grained, and dense to very dense in consistency. <br />A more detailed soil profile is shown on Plates I-1 through I-3, Log of Test Holes <br />(Appendix A). <br />Laboratory Testing <br />Laboratory testing was performed following a review of the field investigation data to be <br />evaluated. Tests included physical testing to determine foundation load bearing <br />characteristics, shear strength for slope stability, earth pressure parameters, and selective <br />classification tests. <br />A. Moisture and Density <br />In -Place density and moisture content values were determined by laboratory testing, and <br />results are included in the Log of Test Holes as shown on Plates I-1 through I-3. <br />B. Mechanical Analysis <br />Mechanical analysis by the hydrometer test method was performed to confirm field <br />classifications. Test results are as follows: <br />Boring No. <br />Depth (feet) <br />Percent Sand <br />Percent Silt <br />Percent Clay <br />B-1 <br />0-3 <br />73 <br />20 <br />7 <br />B-2 <br />0-3 <br />81 <br />12 <br />7 <br />B-3 <br />0-3 <br />77 <br />8 <br />15 <br />4 <br />
