The purpose of our investigation was to evaluate the stability of the previously graded cut and fill slopes. Based on our site reconnaissance and previous subsurface investigation of the subject site, we anticipate that the existing cut and fill slopes constructed at a 2: 1 (horizontal:vertical) slope ratio to maximum heights of approximately 25 and 30-ft, respectively, are surficially and grossly stable. Minor erosion rills were observed within the fill slopes. These areas should be scarified a rninimum of 1-ft below the ground surface, moisture conditioned to near optimum moisture, and recompacted to 90 percent of the maximum density as determined by ASTM D-1557. Proper seeding and planting of the slopes should follow as soon as practical to inhibit erosion and deterioration of the slope surfaces. Proper moisture control will enhance the long-term stability of the finish slope surface. Our investigation was performed using the degree of care and skill ordinarily exercised, under similar circumstances, by reputable Engineers and Geologists practicing in this or similar localities. No other warranty, expressed or implied, is made as to the conclusions and professional advice included in this report. TIris report is issued with the understanding that it is the responsibility of the owner, or his representative, to ensure that the information and recommendations contained herein are brought to the attention of the architect and engineer for the project and incorporated into the plans, and the necessary steps are taken to see that the contractor and subcontractors carry out such recommendations in the field.
