Mr. James Hanson <br />August 2, 1976 <br />Page two <br />due to disturbance of the unconfined surface soil by equipment, --the cone was <br />driven to a depth of approximately 18 inches below the existing grade. It was <br />observed that with depth the soil became increasingly dense, and the blow counts <br />varied between 32 and 54 inches for one foot of penetration. However, in location <br />5, the rod was driven an additional 6 inches to a depth of 24 inches below the <br />existing grade and the penetration from 18 to 24 inches was 20 blows. Therefore, <br />from the results of these tests, it is our opinion that the compaction meets the <br />requirement. However, we recommend that additional testing be performed as fill <br />is placed to final grade. <br />If there are any questions with regard to this report, please do not hesitate <br />to contact us. <br />Very truly yours, <br />SOIL TESTING SERVICES OF MINNESOTA, INC. <br />J - <br />Philip S.
