I <br />SITR EVALUATION RSPOBT <br />JENSEN BOMSB <br />Lot 6, Block 2 <br />MoCULLEY FARM <br />4-18-81 <br />On April 15, 1981 six percolation holes were dug 6 inches in <br />diameter and 3 feet in depth. These holes were tested on April 17 <br />at which time the soil borings were dug 6 inches in difaeter'to the <br />4 foot depth and 3 inches in diameter to the 8 foot depth, The per- <br />colation holes were dug with both a power auger and a bucket type <br />hand auger while the soil borings were dug with the hand augers, <br />The primary site is located west of the proposed house at the <br />toe of a steeper slope where quite a bit of bleak loam had been <br />deposited over the Tars. Because the better soil exists near the <br />surface a shallow trench system should be installed with the tren- <br />ches being no deeper than one foot in the natural soil. Also, since <br />the drainfield area is located at the toe of the slope an intercep- <br />tor drain should be installed above the drainfield to divert any <br />runoff water from entering the treatment area. This trench should <br />be a couple of feet lower than the drainfield trenches with drain - <br />tile being placed in the bottom and rook placed over the top. A <br />few inches of black dirt can then be placed at the surface to es- <br />tablish a grass cover. <br />Additional design information follows. If any other informa- <br />tion is needed, please contact me. <br />Sincerely. <br />PSRCORt INC. <br />Mark 13, Gronberg. P.R. <br />
