J L f / TO: // Jeanne A. Kabusth, Zoning A<’.in ni st valor A rx 7 r. FROM:Michael P. Caffron, Septic System Inspector DATE;May 7, 1979 SUBJECT: Site Evaluation for Sc-ptic System v457 - Johnstc-n S\ibJivision LOT 1 -ilie lot contains the existing house, garage and tennis court. Tlie lot has not been tested for a secondary drainfield site. Condilit.n and location of the existing systems has not yet been pinpointed; however, the owner thinhs his Sifptic tanks are to the west of the house. U’ell locatic>n, te-nnis court, stcc-p slopes, and hardcovcr/pioperty line setbacks as well as a 75' wetlands setback combine to severely limit future expansion area on tliis lot. Tt is likely that the existing system is partially within proposed Lot 2. I woiild recommend that based on location of the existing system and the need for a useful expansion area, the proposed lot line should be moved to the \jcst. Pending a final determination of the location of the existing system, it may be necessary to change lot configurations slightly to preserve the 2-acre dry buildable requirement. 1 LOT 2 - This lot has been tested and would require a mound system or both the primary and alternate fields, 'fhe testing was done near the proposed easterly lot line which may change. Again, the existing system for Lot 1 may be on Lot 2 and lot line changes may be in order. There appear to be adequate soil typos and useful area for drain field to accommodate various house locations. LOT 3 -Lot has been tested and w , *ld be acceptable for a standard drainfield. The lot is severely limited by wetlands on two sides and in the middle, all requiring 75' setback from drainfield The house location could be a critical factor on this lot. A house located anj’whore except abutting the easterly building setback could severely encroach on the useful drainfield area. Without the pi'oper house location this lot may be unbuildable.
