SITE EVALUATION REPORT <br />FOR WILLOW PROPERTIES <br />( GARY PETERSON ) <br />OROKC, KINKESCTA <br />5-30-53 / <br />On Kay 4~30, 1953 six percolation holes were tested on <br />each of 10 lots and 3 soil borings taken on each lot as well <br />in accordance with the provisions of Individual Sewage Sys- <br />ten Treatment Standards(WPG-UO) adopted in 1976 by the Minn­ <br />esota Pollution Control Agency. In addition, other soil bor­ <br />ings were taken in lower areas to determine the possibility <br />of obtaining more than 10 lots but water tables were found <br />to be very high and the soils were found to be very slowly <br />permeable. <br />According to the soils maps and the information we <br />found in the field, the higher areas had very good soils for <br />drainfields while the lower areas and swales had extremely <br />poor soils for drainfields. Thus, we tended to stick to the <br />higher areas while still leaving room for ample building <br />sites. Hov;ever, once houses are proposed to be constructed <br />it .might be desired to shift some of the drainfield areas. <br />Then r w testing would be reouired and it would be ccvise- <br />sble to keep as high up o.u the k.ncbr ■.£ was previously tes­ <br />ted. <br />E-.cn site testeil v;oul j be . cce;. table for eifner stan­ <br />dard or sliHllow trench drr.infield system and is notea on the <br />attaciied drawing. It also might be necessary to use inter­ <br />ceptor drains to divert runoff water but this would be men-' <br />tioned in the system design for the individual houses once <br />they are ready for construction.
