Boggio Administrative Assistant Minutes Public Hearing 680 Reservoir Road November 28, 2022 Meeting Posted: Yes Place: Town Hall, 17 Main Street, Lunenburg, MA Time: 6:05 p.m. Present: Matthew Allison, Matthew Brenner, Amanda Reid, Adam Burney Absent: Erik Torgersen The Hearing was to hear and review an application for stormwater management permit under Chapter 204 of the Code of the Town of Lunenburg for a single-family home at 680 Reservoir Road. The applicants/owners were David and Leigh Sarnoski, 1312 N. Main Street, Lancaster, MA. Brian Marchetti, McCarty Engineering, represented the applicant s/owners. The property consisted of ~11.5 acres ; there wo uld be approximately 1.7 acres of disturbance. Due to wetlands, the house was situated in the upland area and towards the rear of the parcel. They would stay out of the 30 foot no -touch zone, except for by the street as wetlands restrict the frontage. With pavement and ~8,000 square feet of driveway, total impervious was ~1/3 acre. The impervious area was pitched to the south and a peastone diaphragm would run along the south side of the driveway. There w ere two rain gardens on site; one near the street and the other back towards the house. The rain gardens discharge d to the adjacent resource area. The natural flow w as towards the street to a culvert that crossed under Reservoir Road. The Board was in receipt of a review letter from Jeffrey Walsh, P.E., Graves Engineering, Inc. (GEI). The letter indicated no issue with compliance to stormwater requirements of Section 204. There would be a slight increase in the post -development runoff rates. The front yard was raised for the septic system, which GEI stated would cause further flood storage on the abutting property (owned by the Conservation Commission). The Plan was revised to add a drainage pipe running north to south for a flow path. GEI issued a follow-up review letter shortly before the meet ing in which J. Walsh stated that the Plan was revised to include an eight-inch diameter drainage pipe to maintain the existing flow path. Due to the length of the north -south drainage pipe, M. Brenner asked about possible clogging over the coming years . B. Marchetti responded that the pipe was completely on private property and maintenance was the responsibility of the property owner. The Board requested a trash rack (grate -like structure) be installed on either end to prevent large debris from enteri ng and clogging the pipe. Maintenance would be covered in the O&M Plan. ===PAGE 2=== Minutes, 11.28.22 680 Reservoir Road Page 2 The owner was anxious to get started. Due to the timeline of administrative preparation from Decision endorsement through to the conclusion of the appeal period, the owner requested the Board approve timbering to bring in materials while the administrative process was on -going. F or access, the applicant would stump the length of the proposed driveway. Under the Zoning Bylaw, this was not supposed to start until the Decision had been filed. The rain garden proposed at the drive entrance would be used as a temporary settling basin. Board consensus was to allow the applicant to move forward with timbering. Two Special Conditions would be added to the Decision; the trash rack and the extent of clearing. M. Brenner made Motion to close the hearing for 680 Reservoir Road, A.
