RE: Septic System Installation, 502 Haydenville Road
Dear Mr. Flinker:
At its meeting of August 9 , 2012, the Northampton Conservation Commission discussed the
proposed septic work within the buffer zone at your property. The Commission voted that the
work as shown on the attached plan can be considered a field change to the October 27 2008
Order of Conditions for rebuilding of the barn. The Commission found that the work will not
constitute an alteration to the resource area, and can be allowed under the existing Order as it is
located farther from the resource area than work to the barn.
The Commission voted that prior to any septic work, erosion control must be installed between
the limit of work and the pond.
All other aspects of the Order of Conditions remain in effect.
Thank you-
Sarah LaValley
