LEROY CRANDALL <br />AND ASSOCIATES <br />Page 2 <br />by cultivation to depths of two to three feet. The ground surface is relatively <br />level. <br />SOIL CONDITIONS <br />Existing fill soils were not encountered in the exploration borings. <br />Local fill deposits could occur between boring locations. <br />The natural soils to depths of 14 to 25 feet consist primarily of <br />clay. The deeper soils consist primarily of sand and silt with lesser deposits <br />of silty sand and clayey sand. The soils to depths of two to three feet are <br />currently wet and soft. Below the two- to three-foot depth, the soils are <br />moderately firm to firm. The deeper sand and silt are firm. The clay soils <br />are expansive and would swell and shrink with changes in the moisture content. <br />- <br />Water was measured in the borings as shallow as ten feet below the <br />existing grade.Data relative to the water levels are presented on the bor- <br />ing logs in the attached Appendix. <br />RECOMMENDATIONS <br />FOUNDATIONS <br />General <br />Although expansive, the natural soils beneath the site are moderately <br />firm to firm below a relatively shallow depth, and the proposed building may <br />be supported on spread footings established in the moderately firm undisturbed <br />naturdl soils. We recommend that any existing fill soils and the upper. natural <br />soils be excavated and replaced with properly compacted fill and that any planned <br />.
