Sustainable Lexington Committee Minutes of November 29, 2022 the next month the goal is to meet with Jon and Chuck and determine what would work best for moving the document forward. New turf fields proposed for ATM 2023 - concerns about PFAS content. Cindy explained that the Lincoln Park playing fields are targeted for renovation, and there is concern about PFAS and artificial turf. Melissa explained that the three rectangular fields at Lincoln Park are nearing the end of their useful life. Recreation will be asking Town Meeting for replacement of the Lincoln 1 field with another synthetic field. Considerable discussion followed about the costs of synthetic vs. natural, the challenges of a former landfill site, the greater intensity of use possible on synthetic fields (and the value of higher use given that the high school fields will be offline during high school construction), concerns about runoff contaminated by materials used in artificial fields; and the greater heat index experienced on artificial fields. A 2019 memo the Town’s field consultants was referenced that addressed concerns about PFAS in artificial turf and the inability to accurately measure it at the time, which Cindy will circulate to the committee. Melissa invited members of the committee to attend the CPC meeting next week. Cindy asked who might be willing to attend the meeting and prepare beforehand; Rick volunteered but said his time is limited, and Cindy left open a call for another volunteer. Town staff were thanked for attending. High School Building Committee Update. Dan reported that the committee had a good discussion at their last meeting and will be meeting again in January, and would welcome any communications from anyone with questions or concerns. Lin asked if any thought has been given to how to dispose of whatever is demolished or deconstructed. Mike explained that they haven’t yet; Dan added that it’s important to raise these questions about building outcomes now because the time pressure will be enormous once we’re in the MSBA pipeline. Transition to Town ‘Solar Buildout Plan’ from assessment of the Town's solar potential. Maggie reported that, following on Dan’s analysis, the Town Manager will bring the question to the Select Board of whether we want to undertake more analysis and planning. Dan noted that it’s also well within our responsibilities to bring it to the Select Board ourselves. Update on facility projects: •Mike reported that the solar hot water project for the town pool passed at Town Meeting and they have started to design the project, with a heat pump for back-up. They expect to be sending it out for bids by January and hope to have it up and running before the start of the pool season Memorial Day weekend. •All the school solar canopies should be connected by the end of December. The fire station array is now operational, and the police station solar canopy design will go to the HDC Thursday evening, with the goal of having a final design ready for Town Meeting. .3
