Approval of past meeting minutes. The minutes of October 25 were approved as written.
Comments from residents; emails to committee mailbox; new business.
•Todd reported on the email inbox. The Cub Scouts asked again if someone from SLC could
attend a January 26 meeting to talk about being involved in town government. Todd has let
them know that he will attend the meeting. Rick offered to help if needed. Todd also
responded to a request from another town for information about our heat pump program.
•Cindy announced that Andy Joynt was appointed by the Select Board to the open position on
the committee the evening before. Because he hasn’t completed the open meeting law and
ethical training required, he cannot vote this evening, but hopefully will be fully qualified by
the next meeting. Everyone expressed their warm welcome.
Sustainability and Resilience Officer updates:
•High performance building policy update: Maggie introduced us to the current versions of
the two documents she circulated by email (the guidance is new), reviewed some highlights,

and noted a few things that have been modified since our last discussion. These include the
inclusion of ground-mounted solar and not just building-mounted solar in reporting, air
quality details, additional detail on toxics, pesticides and IPM, and trees. Issues that were
brought up by committee members and discussed: accounting for stand-alone solar (i.e.,
energy sent to the grid) v. behind-the-meter solar (i.e., energy used by the building) and the
recommendation to stay aligned with the approach used for BEU-D; concern about use of
artificial materials that can be proven later to contain toxics v. natural materials (e.g. grass v.
artificial turf).- Mike Cronin clarified that this policy is focused on Facilities not on fields,
and the committee member commented that maybe there should be a parallel effort for DPW
and Recreation; current and desired indoor measurements of CO2 and particulate matter.
•Waste: trash and recycling; food waste; zero waste plan: A new waste contract continues to
be discussed with the task force. DPW is reviewing various proposals, some of which are not
at a workable price point, and they are exploring how to bridge the next year while looking
ahead to larger waste disposal changes in the year following. Questions were asked about
how to counter the perception among some residents that materials separated from the other
waste for recycling are not, in fact, being recycled, and about the pilot Black Earth
composting program in DPW’s Program Improvement Request budget, which will target
about 700 new customers in addition to the 1300 existing ones. The draft of the Zero Waste
Plan has been received from the consultant and is being reviewed by the task force.
•BEU-D: the town’s reporting guidance is being finalized, and Maggie is planning a training
program next year for affected owners.
•Heat Smart: The town’s heat pump program is about to launch, with eight volunteer advisers/
coaches now trained and ready to go. Maggie hopes to have it live in a week or so.
•LexHAB: Maggie and Cindy are working with LexHAB on a two-session event for LexHAB
residents on how to lower energy costs through a variety of available programs, including
community solar and hope to eventually expand it to the Lexington Housing Authority and
other eligible town residents.
•Green Fleet Policy: The policy was adopted in 2021 and calls for maintaining an inventory
and preparing a transition plan. Maggie has begun to work on both.
•Climate Action Plan: The branding committee has completed its work, and there is a logo and
tag line: “Resilient Lexington: Our Pathway to a Sustainable Future”.
SustainabLY update: Tanay reported that they have been researching possible projects, including
the application to the library, and are brainstorming issues they want to promote or advocate for,
such as small business composting, electronic waste recycling, and single-use plastics.
Integrated Building Construction and Design Policy. Celis reported that they have met with the
Permanent Building Committee to present the current draft and are getting good feedback. Over

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.

Annual Town Meeting 2023 - Article to adopt municipal opt-in specialized building code. Cindy
explained that the new stretch code will become effective for residential properties on January 1,
2023 (with an additional phase-in for HERS ratings in 2024) and for commercial properties on
July 1. Adoption of the new specialized municipal opt-in (sometimes called net zero, but isn’t
quite), requires Town Meeting action. She and Maggie have met with building staff to improve
understanding of the new code. After some discussion, it was voted unanimously to ask the
Select Board to put an article on the Annual Town Meeting warrant to adopt the new specialized
opt-in code.
Investigation of networked geothermal in Lexington. Cindy explained that a lot is happening on
networked geothermal around the country and we should try to move this forward in Lexington.
Hartwell is a promising location with interest from the Town Manager. She and Maggie have
been discussing this with Ken Karnofsky, who couldn’t join us this evening. She asked if
someone on the committee would be interested in working on this and exploring ways the town
could help move this forward. Andy volunteered. Some discussion followed about possible
business models and the challenge of working with the utilities. Mark noted that there is the
potential for significant grants from the federal government.
Tree Statement of Concern. As an FYI, Charlie explained that a group of tree advocates,
including Rick, Marcia, and Ricki as well as himself, have been meeting to discuss how to raise
awareness of the importance of a robust tree canopy in town as a defense against the localized
impacts of climate change, and how to build political support for measures to do more. They
have written a Statement of Concern that Charlie circulated to the committee a few days ago, and
will be presenting to committees, organizations in town, and the general public in the next few
weeks/months. A few questions were asked, and it was agreed to put it on the agenda for the next
committee meeting.
Next Meeting: The next regularly scheduled meeting of the Sustainable Lexington Committee
will be held at 6 pm on December 20, 2022.
The committee voted to adjourn at 9:06 pm.
Respectfully submitted,
Charlie Wyman
