J. H. KLEINFELDER & ASSOCIATES <br />11 <br />File No. S-2568-5 <br />November 23, 1983 <br />Page Two <br />The results of the exploratory boring and laboratory testing indicates the <br />soils below the site are relatively fine-grained. The field percolation test <br />results are shown on Table L The average field percolation test result is 40 <br />minutes per inch. <br />Based on <br />this <br />information and experience for <br />such disposal systems, we anti- <br />cipate storm <br />water <br />will percolate at a rate of 1 <br />to 4 inches per day. A per- <br />colation rate <br />of 2 <br />inches per day should be used <br />for design. The variation in <br />this rate will <br />be a <br />factor of moisture content of <br />soil below ponds, surface con- <br />dition at bottom of ponds, and pond depth. <br />The recommendations made in this report are based on the results of our <br />field explorations and our understanding or the proposed construction. The <br />soils data from which this report was prepared are based on the results of five <br />test borings and five percolation tests made for this investigation. It is <br />possible that variations in the soil conditions could exist between or beyond <br />the points of exploration. Therefore, if any soil conditions are encountered <br />during construction which differ from those assumed in preparation of this <br />report, our firm should be notified so that we can review the situation that <br />exists and modify our recommendations if needed. <br />J. H. Kleinfelder do Associates has prepared this report for the use of <br />Mr. Dave Olmstead for design purposes in accordance with generally accepted soil <br />and foundation engineerinng practices. No other warranty, expressed or implied, <br />is made as to the professional advice included in this report. <br />This report is also issued with the understanding that it is the client's <br />responsibility to ensure that the information and recommendations contained <br />herein are called to the attention of the designer for the project and that <br />necessary steps are also taken to see that the recommendations are carried out <br />in the field. <br />We trust this report contains the information required. If you have any <br />questions regarding this report, please contact us. <br />Respectfully submitted, <br />J. H. KLEINFELDER & ASSOCIATES <br />Michael R. Erwin, C.
