BROWN ROAD <br />7-29-83 <br />On Jxoly 23-26, 1983 two percolation holes were tested and two aoil <br />borings were taken on the above property according to the provisions of <br />Individual Sewage Treatment Systems Standards ( WPC-40) in order to find <br />another area for a new drainfield. The area chosen was on a flat slope at <br />the base of a bank which is at least 75 feet back from the marsh and at <br />an elevation of about 4 feet above the swamp or marsh. <br />The soils were fairly sandy and had very good permeability which <br />■would require a shallow trench system because of the possibility of a • <br />high water table. However, in order to maintain at least 3 feet of i > . <br />separation between the bottom of the trench and the water table, some <br />•A., i <br />•* . * •. * -Vf* ^ <br />loanQT sand or sandy loan fill will be needed to be placed before <br />construction of the trenches. Also, grading should be done <br />in order to divert runoff water from entering the runoff <br />site. Sinc'e the water level in the borings is the same as <br />that of the marsh, an interceptor drain will not be necessary <br />with the systeri. <br />Additional system design ir.formation follows. If any <br />other infirroajion is needed, please contact me. <br />Sincerely, <br />FERCOR, INC. <br />/ <br />Mark S. Gronberg, P.E. <br /><1
