Waitt, Jr., Meridian Associates, Jason Hicks, Artis Senior Living, Gary Larson, Landscape Architect Mr. Grant stated that this project will be presented at a hearing in front of the st Planning Board on May 21. Mr. Kirby gave a description of the site and proposed removal of fill and debris as well as a restoration plan for the area. The structure is proposed as a one-story building, approximately 30,000 sq. ft. with a loop style driveway, 24’ wide to accommodate for emergency vehicle access. Mr. Kirby explained the 2010 restoration plan effort and the proposed restoration plan for 2014. Mr. Novak explained how the infiltration systems will function. Comments from the Commission as follows: Ms. Miller read the engineering review stating:  Soil tests were done and the soil is predominantly fill  Engineering has had several opportunities to review these plans in the design process  A comprehensive drainage report was submitted. The calculations are responsible. They show a reduction in runoff from the site after project completion compared to pre-existing conditions  The project includes a stormwater infiltration system to compensate for the loss of permeable surface area  Engineering is satisfied with measures shown to protect existing sanitary sewer that crosses the property. The construction of the culvert crossings will have to be done with coordination with DPW  Engineering expects to have the opportunity to review the design for the retaining walls when they are available  As-built drawings of the utilities on the site will have to be submitted and approved on completion of the project Mr. Langseth commented on pre and post development runoff. The Commission discussed the old pipe outlet location and Mr. Novak explained a new pipe is proposed to completely replace the old pipe. Mr. Bitsko commented that the planting schedule is acceptable, but the language regarding monitoring needs to be clarified to reflect over a five year period. The Commission and Mr. Kirby discussed the bordering vegetated wetlands and wetland boundary. Mr. Kennedy asked how the culvert design was determined. Mr. Novak replied that the culvert will contain a headwall and two pipes which will help wildlife movement. Mr. Wolk asked about the access for Fire Department all around the proposed building. Mr. Kirby responded and stated the width of the access driveway was discussed with the Fire Department. Mr. Wolk asked for the construction sequence schedule. Ms. Miller read a letter into the record from an abutter. Bob, Trustee of Swammonland Trust voiced concerns about vernal pools and wildlife in the area. He asked what the impact this project would have on the brook. Mr. Novak replied that there is no increase in runoff as a result of this proposal. David Kessler of 20 Barberry Road commented on mitigation for this area in the past and asked if there would be light pollution. Mr. Kirby explained that DEP required Mr. Sellars to restore the area. Mr. Larson stated that zoning regulates lighting in which the light source needs to be kept inside a container with lenses and shields directed downward. A lighting plan will be submitted because no light is allowed beyond the property boundary. Mr. Langseth asked for the plan to show the light impact on the wetland areas. Michael Bliss of 13 Barberry Road commented on the high water table. Motion made and seconded to continue the hearing to June 3, 2014 at 7:00 pm at the request of the applicant, 7-0 in favor. 8:32 pm Cont.
