Parker Room, Town Office Building 1625 Massachusetts Ave Chair Philip Hamilton opened the meeting at 6:32pm in the Parker Room of the Town Office Building Commissioners Present: Phil Hamilton, Alex Dohan, Dick Wolk, Kevin Beuttell, Ruth Ladd, Duke Bitsko Others present: Karen Mullins, Conservation Administrator and Casey Hagerty, Conservation Department Assistant 6:32pm 5 John Hosmer Lane, Ph. Brook II Lot 6, Order of Conditions, 201-290, BL243 Compliance Status Cindy Sherman- representative Ms. Sherman explained that an Order of Conditions was issued on this property in 1990. The project was completed but a Certificate of Compliance was never followed up on. One of the requirements of the Order was for a Conservation Restriction to be placed on a portion of the property. During this process, two issues were discovered. The first was that the driveway was built outside of the easement area. The second is that part of the rip rap wall of the tennis court was intruding into the Conservation Restriction area. In order to address these problems, the applicant has revised the plan to move the easement to include the driveway area and pull back the CR so that the wall of the tennis court is not included in the restricted area. Questions and comments from the commission: The commission has how much of the wall extended into the originally proposed CR area. Ms. Sherman explained that she was unsure of the exact amount but it was very minor. She stated that they looked at extending the CR in another area on the site, but they were limited by an easement that runs through the site. The commission asked what the time line for achieving the Certificate of Compliance is. Ms. Sherman explained that at this point, she is asking the commission for feedback on the Conservation Restriction before she submits it to the state. Once the state approves, they will come back for their Certificate of Compliance. The commission stated they are comfortable with the changes to the proposed Conservation Restriction. 6:46pm Insignificant Plan Changes Request: DEP 201-1066, BL 1023, Brookhaven, 960-1010 Waltham St. Mr. Dick Wolk recused himself from the hearing. Jim Borrebach, OHI Engineering, Bill Dailey- attorney, James Freighling- Brookhaven Mr. Borrebach explained that during the Planning Board process a few changes were made. Additionally, once the architectural and mechanical plans were drawn up a few changes were made to the site plans. The changes were mostly related to the stormwater runoff amounts. They have made some slight revisions to the stormwater systems and are able to meet the Town By laws in all areas. Mr. Borrebach stated there are some other small changes including removing one proposed gazebo, moving a sidewalk, and shifting underground utilities. The sewer connection has been slightly modified to create a drop and allow for better flow. Additionally, he stated that there is a possibility that they will have to bring the electrical utilities through duct bank over the culvert rather than from Waltham Street as originally proposed. They should be hearing from the electrical company soon about this change. Questions and comments from the Commission: The Commission asked if the Engineering Department has signed off on the proposed changes to the stormwater system. Ms. Mullins stated that they have. The commission stated that if there are any additional changes to the stormwater system, the applicant will have to come back to the commission for approval. The commission asked when they should be hearing from the electrical company. The applicant stated that they should be hearing from the electrical company in the next few weeks. They will know the result prior to creating the duct bank. Motion to approve insignificant plan change made by Ms. Ladd and seconded by Mr. Beuttell.

They are proposed to demolish the existing fire station and build a new one in its place. Currently, there is no stormwater management on the site. They are proposed different BMPs to manage all the stormwater on site including biorentention basins, sediment forebays, and subsurface infiltration systems. They are also proposing to use permeable pavement in the parking areas in the rear of the station. All of the work proposed is outside of the buffer except for the invasive species removal. Mr. McGary stated that the site is divided by Camelia Way. They are proposed to relocate the parking along Camelia Way to the side further from the wetlands. Mr. Liddy explained that they have submitted a planting mitigation plan for the proposed work. There was an error in the narrative; they are using a New England Wildflower grass mix for the ground cover rather than garlic mustard. They are proposing manual removal of the invasive species except for knotweed which they will use pesticide. Mr. Hamilton entered the Engineering Report into the record. Mr. Hamilton entered comments from the Planning Board and Historic District Commission into the record. Questions and comments from the Commission: The commission asked whether Camelia Way is an easement or Right of Way. Mark Barrett, Lexington Facilities Department, stated that they are working with Town Counsel to determine that. They are planning on referring to it as an easement. He stated that during construction, the businesses behind the Fire Station will have access to Camelia Drive. The commission asked for more detail regarding the estimated seasonal high ground water. The applicant stated he will provide that. The commission asked how the pervious pavement was modeled. Mr. McGary explained that he did not take that into account in the stormwater calculations. The commission asked if the applicant could add a deep sump to the catch basin that does not have any proposed pretreatment. The applicant stated they could. The commission asked for more details regarding the oil water separator. The commission expressed concern that it would not work as proposed. The commission asked that the applicant look at planting more street trees. The commission stated that they want native species not cultivars planted on site.
