At the time of the 1989 reconnaissance,the site�vas devoid of vegetation as a result of recently <br /> ' grading activities. M existing building foundation and 7-foot deep by 5-foot diameier cistem were <br /> located in the western poRion of the site. These sWctures were removed as paA of the original site <br /> development and were locaied outside of the areas of the proposed addition. The site s!oped gently <br /> downward from east to west having an overall m�ief of approximately 3 ft. Exploration of subsurface soil <br /> conditions at the site was accomplished by excavating four test piu (TP-1, TP-2, TP-3, and TP-4) with a <br /> rubber-tired backhoe at the approximate locations shown on Figure 2. <br /> .� <br /> IJ <br /> ` I • <br /> I52&U21:1PROJECT11011005010�FASTAqNT qPT.DOC I-2 I.MIDAUA$$OCIATES � <br />
