Reducing Waste and Protecting Ecosystems

We work closely with many local partners like LexZeroWaste, Lexington Living Landscapes, and many more organizations for maximum impact.

Advocating for Policy Change

LexCAN has helped turn climate ideas into town bylaws — including the nation’s first gas-powered leaf blower ban and a law banning fossil fuels in new home construction. Advocacy isn’t just talk.

Lexington High School Building Project: Environmental Justice Community Meeting

February 5th 2026 | 6:30 pm - 8:30 pm

Join Zoom Meeting Here

The Massachusetts Environmental Protection Act (MEPA) review process provides opportunities for public review of a project’s potential environmental impacts. The town of Lexington’s School Building Committee’s Lexington High School Project will host a virtual Environmental Justice (EJ) community meeting to specifically engage EJ communities and community-based organizations on the project and MEPA process.

The Lexington High School Project would involve demolition of the existing school building and its associated infrastructure to address aging facilities, expand shared spaces, enhance safety, and ensure resiliency. The project is currently undergoing environmental review under MEPA procedures, where an Expanded Environmental Notification Form (EENF) was filed on August 15, 2o25, and an EENF certificate was issued on October 17, 2025. The project team has commenced work on preparing a Single Environmental Impact Report (SEIR), as a requirement of the EENF Certificate. The EENF Certificate also encouraged the town to continue public outreach, including opportunities for the public to learn more about the project and continue to offer comments and ask questions as the project goes through the Remaining Environmental Review Process. The meeting on this date is one such opportunity. The Town of Lexington School Building Committee is committed to providing ample access and opportunity to stay up-to-date on this project, consistent with the EENF Certificate. Previous meeting information and further project details and further understanding and involvement of this project is available through MEPA or the Lexington High School project website.
