The homeowner asked that tree cutting be kept to a minimum. To best obtain this directive the contractor placed a small portion of the trench within 10 -feet of the lot line. The closest distance is 5 -feet as scaled on the Record Drawing. This should not affect the neighbor lot. The neighbor well has sufficient separation @ 135 -feet. The septic system is not close to the neighbor system. Please grant this small waiver amount to the lot line. Thanks -Steve e ��F OF ®B.. Steve Esq % O�Sy C�j - n256 AN ��► � ai n w It, rt_ P.O.

A new design is submitted to mitigate this damage. A new soil test reveals SW w/gravel and no groundwater; no bedrock at depth. The design calls for a new trench and a new septic tank. Slopes and easements are depicted on the drawing. The terrain is generally a flat slope at the trench site, and the remainder of the area. The system design size is a duplex at 6 bedrooms. The existing system was designed under direction of DEC. No records of construction. I contacted previous engineer Lou Butera & he gave no construction information. Please review the wastewater system design for the existing duplex. I have included design plans & specs, design guidelines, & soil test.
