Re-locate an existing driveway associated with a raze and rebuild of a single- family dwelling within the 200-foot Riverfront Area Present for the Applicant: Rich Kirby, LEC Environmental Consultants, Inc. and Brian Morin, CJM builders Mr. Kirby stated the re-location of the driveway is within the jurisdiction of the Commission. The demolition and rebuild of a single-family dwelling is outside jurisdiction of the Conservation Commission. One tree is proposed to be removed. Comments from the Commission as follows: Ms. Miller read the engineering report stating, “This project is demolition of a dwelling and construction of a new single-family dwelling. A report of soils test results is on the plans. Calculations are responsive. New impervious area is offset with a subsurface infiltration system. The calculations show that the rates and volume of runoff after construction are less than existing conditions for the design storms. Water and sewer services are shown on the plan. The infiltration structure in the front yard must be situated such that it does not overlap the water and sewer services. Operation and maintenance instructions are part of the drainage report and are sufficient. The construction should be inspected by a design professional and as built drawing should be submitted to the Town Engineer. During construction, erosion and sedimentation control procedures should be in place. This should include a wheel-cleaning area for construction vehicles.” In response to Mr. Bitsko’s question, Mr. Morin commented that the stone pad would be removed after construction. Edward Cheng of 23 Ledgelawn Avenue asked about the direction of runoff from the re-location of the driveway. Mr. Kirby commented under the proposed conditions an infiltration system will capture runoff, therefore not displacing water onto other properties. Ms. Mullins commented relocating the driveway causes less impervious surface to be within the Riverfront Area. Motion made by Mr. Wolk and seconded by Ms. Dohan to close the hearing, 4-0 in favor. Ms. Dohan stated that after checking with Lynne Pease in the Selectmen’s Office, she can participate on both the Conservation Commission and Greenway Corridor Committee, as well as vote on both. Ms. Dohan will need to recuse herself when it becomes a conflict of interest. Ms. Dohan commented that she is unable to be an official liaison for the Greenway Corridor Committee, but the Conservation Commission does not need one. 8:27 pm Motion made by Mr. Wolk and seconded by Ms. Dohan to adjourn the meeting, 4-0 in favor.
