SITE EVALUATION REPORT <br />FOR BRUCF. DREN HOMES <br />LOT 4, BLOCK 1, McCULLEY FARMS <br />Orono, Minnesota <br />5-6-85 <br />On May 2-3, 1985 six percolation holes were tested and three soil borings <br />..en on the above property in order to determine suitable drainfield sites <br />for both a primary system and a possible future alternate site. Testing was <br />done under the provisions of Individual Sewage Treatment Systems Standards <br />(WPC-40). <br />Originally some soil borings were taken to the southwest of the proposed <br />house, but because of water running in the holes it was decided to test at <br />the higher flat area to the northeast of the house. While the soils here were <br />fairly good, there still was enough of a water table .so that a shallow trench <br />system would be needed on the primary site(holes 1-4) and a mound on the alt- <br />ternate site. Also, the use of an interceptor draintile is recommended to <br />divert runoff water from the drainfield site and lower the water table. This <br />may preclude the use of a mound on the alternate site in the future. <br />Additional system design information follows. If any other information <br />is needed, please contact me. <br />Sincerely, <br />PERCOR, INC. <br />Mark S. Gronberg, P. F. 7 <br />
