Mr. Capachietti stated that the applicants installed temporary above ground propane tanks on site during the National Grid strikes. The approved gas line was supposed to go beneath the parking area before the lot was built. Due to the National Grid strikes the gas line was instead installed along the edge of the parking area. The now situated gas line now presents an unfavorable location for a proposed restoration area. The area was seeded but the trees that were proposed to be installed were replaced with a Canadian yew hedge instead to provide for screening. The Commission asked what the restoration efforts were along the trench line. Mr. Kirby stated that the trenched area was reseeded. Abutters, Ms. Jill Barres and Ms. Sharon Hayes, located at 426 Concord Avenue, raised their concerns regarding the adequacy of the screening, the relocation of the gas line, the fill that has been installed and the snow storage areas. It was discovered that the gas line is incorrectly shown on the submitted plan. The applicant stated that the retaining wall installed limits the planting options. The Commission asked what the setback is between the gas line and the property line. The applicant stated that there is about a six to eight foot setback.
