SITE EVALUATION R13PORT <br />FOR DAVID NITZ <br />Lot 79 Block 1 <br />FARVIEW <br />9-4-79 <br />On September 1, 1979 six percolation holes were tested and <br />3 soil borings taken. The percolation holes were dug to a 42 inch <br />depth with 6 inch diameter hand and power augers as were the soil <br />borings to the 4 foot depth. The remaining depth for the soil bor- <br />ings was dug with a 1 inch diameter hand auger and a 3 inch diame- <br />ter power auger. <br />The average percolation rate for the six percolation holes <br />was 7.2 minutes per inch. Mottled soil existed in soil boring # 3 <br />at 4.5 feet and in soil boring # 2 at the same depth. There was <br />some alight mottling also in hole two at 2.5 feet in the clay lay- <br />er which was underlain by a sandy loam layer which extended to the <br />4.5 fo3t depth were a clay loam and more mottling existed. Because <br />of the slope of the lot quite an amount of water flows down through <br />this drainfield area. This water must be diverted by grading above <br />this drainfield area. It will also be necessary to install an inter <br />captor drain at least 10 feet upslope from the drainfield area and <br />5 to 6 feet deep with rock being placed over this drain and some <br />black dirt and grass cover at the top. This will also help to di- <br />vert water from the drainfield area. Besides these measures it will <br />necessary to install a shallow trench system with the drain tile <br />being installed about a foot deep in the natural soil. <br />
