� <br />r SITE EVALUATION REPORT i <br />FOR THE EDGAR HERTZ PROPERTY <br />_.- 1820 FOX STREET, ORONO <br />5-31-80 <br />On May 17, 1980 Rix percolation holes were tested and <br />s <br />three soil borings taken. The percolation holes were dug 6 <br />inches in diameter to a 42 inch depth. The soil borings were <br />dug 6 inches in diameter to the 4 foot depth and 3 inches in <br />diameter to the remaining depth by hand augers. <br />The average percolation rate for the tour holes in the <br />primary drainfield site was 21.5 minutes per inch. This rate, <br />along with the lack of a high water table woula enable this <br />site to meet the requirements for a standard drainfield. There <br />ie a topographical problem which will require the trenches to <br />be constructed In a v-shape in order to remain relatively level <br />for the entire length of the trench. <br />The alternate site also meets the requirements for a stan- <br />dard drainfield system. However, this area is higher than the <br />probable building site 3o a T;uT^ .would rro3t likely nrcc to b <br />used in this situation. <br />More information concerning the design of the system will <br />• <br />be needed once the size and location of the house are known.If <br />there are any questions or additional informatioA!.needed, plea:-e <br />contact me. <br />Sincerely, <br />PERCOR, INC. <br />Mark S.
