. . . <br /> THIS ITEM HASSITE EVALUATION REFORT BEEN <br /> FOR TIM ADAMS MICROFILMED <br /> THE FARE AT LONG LAKE <br /> 12-2.8-62 <br /> On October 28-29, 1982 and November 13-14, 1982 six lots <br /> were tested to determine what type of drainfield would be <br /> possible on each of the lots . Three perco],ation holes were <br /> tested on each lot and one soil boring. ilt the time a house <br /> , is to be constructed, some additional testing will be needed <br /> but the testing done now gives a very good indication what <br /> type of system can be used on the primary drainfield site . <br /> The percolation holes were dug 6 inches in diameter to <br /> the )1.2 inch depth while the soil borings were dug 6 inches <br /> in diameter to the 4 foot depth and 3 inches in diameter to <br /> ' the remaining depth. <br /> An average percolation rate of 27.4 minutes per inch on <br /> lot 2 with no high water table would allow a standard system. <br /> Lots 12 and 13 are to be combined and had an average rate of <br /> 20.7 minutes per inch but because of a possible high water <br /> table, a shallow trench system should be used. Lots 16 and 17 <br /> were also combined and had an average rate of 25.0 minutes <br /> 14, <br /> per inch with no high water table which would allow a stand- <br /> ard system. Lot 18 had a lot of black loam with some heavy, <br /> wet clay soils underneath and had an average percolation rate <br /> of 48.7 minutes per inch. A shallow trench system will be <br /> needed with black loam brought over the trenches for cover. <br /> Also, it would be helpfull if some grading was done or a pond <br /> made to keep the runoff water to the north side of the lower <br /> flat area and away from the drainfield area. <br />
