Boggio Administrative Assistant Minutes Public Hearing 1325 Massachusetts Avenue January 27, 2020 Meeting Posted: Yes Place: Town Hall, 17 Main Street, Lunenburg, MA Time: 7:00 PM Present: Matthew Allison, Tanner Cole, Marisa Thompson, Paula Bertram, Adam R. Burney The Hearing was to hear and discuss a stormwater management special permit under Ch. 204 of the Code of the Town of Lunenburg for an earth rem oval project at 1325 Massachusetts Avenue, Map 062, Parcel 0003. Owners/Applicants are Daniel and Jean Proctor, 1529 Massachusetts Avenue, Lunenburg, MA. Owners/applicants were represented by Frank McPartlan, Ducharme & Dillis Civil Design Group, Inc. (‘DDCDG’). The project calls for the removal of 50,000+/ - cubic yards of material. The site is mostly grassed with woodlands along the perimeter . A single family residence is located on the lot. A twenty foot buffer, to remain untouched and wooded, wil l be maintained along the property lines. The site will be graded to a large flat 1% pitched area, which will drain to a stormwater management area (a basin with infiltration capacity) on the west side of the property . That will discharge into the existi ng wetland buffer. An earth removal permit has been received from the Select Board. As the site is zoned commercial, the property owner wanted t he stormwater management area designed to capture runoff from the earth removal as well as any impervious area that may occur with future development. The basin has been designed up to a 100 -year storm. The basin has been created with forebays, one at each end and one in the middle. Three manholes are proposed for any future development. The outlet structure i s designed to promote groundwater recharge. The site will not discharge to any critical area. During earth removal, a double row of silt fence will be placed along the wetland side of the property. Slopes will be stabilized with erosion control matting. The flatter areas will be stabilized with wood chips until seeded. A gravel access drive will be constructed once approval is received from MassDOT. P. Bertram disagreed with DDCDG’s comment that the site would not discharge to any critical area. S he had looked at the ACEC (Areas of Critical Environmental Concern) map and opined that this address falls within an ACEC. The map of the Cowdrey area shows an ACEC going down Townsend Harbor Road and across Massachusetts Avenue. P. Bertram has concerns with pre- and post- development stormwater and is of the opinion that the Board should be looking at this from both the earth removal viewpoint and possible future commercial development. She felt the Board is only looking at a small portion of this project, while there is a large r one coming. A. Burney responded that the Board can only act on the current application, not something that may take place in the future. DDCDG reiterated that the basin was designed to handle 77,000 s quare feet of impervious s urface. P. Bertram noted d rainage calculations were available, but a full stormwater plan was not done as the project meets pre - and post - requirements. She also questioned if there was sufficient hydrology information. P. Bert ram inquired as to a planting plan. DDCDG responded that plantings are shown on the Earth Removal Permit Plan. ===PAGE 2=== Minutes, 1325 Massachusetts Avenue Page 2 D. Proctor noted he will be doing a site walk with abutter Dale Erskine to determine what trees are to remain. Arborvita es will also be planted along her property line. P. Bertram is looking for a sequencing timeline for stormwater stabilization. DDCDG responded erosion control barrier s will be installed first along the limits of the property . Where earth is to be removed, the basin will be constructed first . P. Bertram would like this documented. A. Burney noted an email he received f rom abutters Gerry and Dale Erskine, 1331 and 1335 Massachusetts Avenue. They had concerns with noise, dust, duration of project, and buffer materials. Full email is on file in the Planning Office. A. Burney noted most of their concerns are with earth removal, not the stormwater management. A peer engineering review letter was also received from Graves Engineering, Inc. (GEI) after th e close of business. A. Burney summarized that review letter for the Board. GEI had no issues with compliance to the Stormwater and Storm Sewer Bylaw. There were review comments relative to Hydrology Computations and Stormwater Management and general en gineering comments. Review let ter is on file in the Planning Office. P. Bertram would like to see screening and proposed stabilization on a revised plan . She is also looking for assurance that the project complies with best management practices for an ACEC and wants a vegetation/planting schedule and sequencing schedule. DDCDG requested the hearing be continued to February 10, 2020. A. Burney will relay the Board’s questions/concerns to GEI for response. P. Bertram made Motion to continue the Hearing to February 10 th, T. Cole Seconded, all aye. Hearing recessed 7:50 PM.
