Duke Bitsko – Aye Kevin Beuttell – Aye Alex Dohan – Recused Ruth Ladd – Aye David Langseth – Aye Holly Samuels – Aye Phil Hamilton – Aye Request for Insignificant Plan Change: Engineering/Wright Pierce, Marshall Rd Pumping Station, Construct retaining wall to accommodate grade changes and proposed planting plan Mr. Mark Maccio, project engineer from Wright Pierce presented before the Commission on behalf of the Town of Lexington’s Engineering Dept. Mr. David Pavlik of the Engineering Dept. was in attendance. They are proposing to construct an eighteen inch high retaining wall around the rear of the pumping station equipment in order to mitigate the steep slope on the property. A planting plan was proposed for the rear of the pumping station past from the retaining wall to the edge of the station area. Ms. Marilyn Fenollosa, an abutter to the project, inquired about the materials of the retaining wall and asked that the material look natural. Mr. Maccio stated that the keystone retaining wall system is to be made of pre-cast blocks that have a capstone on top. They are willing to change the wall material to rock or another more natural looking feature. Ms. Samuels suggested adding plants that would provide more screening such as evergreens. The Commission will discuss the proposed change at a future meeting. Request for an Information Meeting: Engineering/Wright Pierce, Hayden Ave and North St Pumping Station Upgrades Mr. Mark Maccio, project engineer from Wright Pierce and Mr. David Pavlik of the Lexington Engineering Department presented before the Commission. Mr. Maccio stated that the town intends on upgrading the existing pumping stations to a new submersible type pumping system. The existing station on Hayden Avenue is the second largest in town and is located close to wetlands. There is an easement on the property which they currently intend on working around. They are proposing invasive species management and vegetation for slope stabilization. Chairman Hamilton suggested that the Commission arrange a site visit. Mr. Maccio stated that they wish to relocate the North Street system to a higher ground elevation and possibly install a pathway connecting the street to the Recreation Trail. The decision to relocate the system was in order to avoid filling in the area.
