� . <br /> S Mr.Charles Thompson <br /> Project BL-04-05907 <br /> � October 27,2004 <br /> Page 5 <br /> � ' <br /> , <br /> = Underground utilities brought into the site should avoid crossing the areas of deep fill and organic soils, <br /> � if possible. It appears that the most prudent area for utilities entering the site would be from the <br /> � northeast corner of the site. <br /> � G3. , Building Pad Preparation <br /> � We recommend the vegetation and organic soil be removed from the proposed building pad and oversize <br /> � areas. The following tabulation indicates the anticipated excavation depths at the boring locations. <br /> '�, Table 1.

The surface compaction will aid in densifying soils disturbed during soil <br /> , excavation. This work should be observed by a qualified geotechnical engineer or his representative. <br /> � <br /> � ' <br /> � <br />
