Sustainable Lexington Committee Minutes of June 22, 2023 !Marcia asked whether canopies be put on roofs over heat pumps. Mark said yes, but there are height restrictions. Cindy and Lin suggested that maybe that could be an allowable use and not impact height. o Rick suggested that the town could apply to put solar on the sound walls on Rt 128 since that project has been slow. The highway department created the application process to support those types of efforts. He does not know why people are not taking advantage of it. o Lin suggested that the Town engage a consultant to help move solar installations forward and actively reach out to building owners and invest in solar. She thought that maybe Mass CEC would support it. o Lin suggested that there should be a zoning bylaw to require solar for new developments. o Celis reminded the committee of the opportunity be an offtaker for the solar array developed in Sandwich, MA and suggested that the town should consider future opportunities.

The average jet flight into Hanscom is a 2.5 hour flight. !Hanscom has released an RFP to build hangers over a ¾ mile stretch of the property that would add 2.3x the current private jet hanger space. This would logically mean an increase of 2.3x the number of current private jet flights. •Andy asked whether the increase in hanger space necessarily meant that there would be more flights. Mark replied that there is some argument that the hangers will decrease “ferry” flights, but he expects that increased jets mean increased flights. o Mark walked through a presentation describing his estimates for emissions from Hansom and the proposed increase in flights. !Rick commented that in addition to CO2, the emissions are similar to diesel and include toxics. !Mark commented that Massport is working to get rid of piston aircraft, and move to jets. Also, Cape Air is looking at buying Eviation Alice electric planes – limited to a .6
