At the June 23 Conservation Commission meeting, the Board took a major step in the development of the Lexington High School project at 251 Waltham Street by approving the Order of Conditions.
This is a high-stakes decision for our community. The approval allows for significant wetland incursions—including impacts from the parking lot and the school building itself—and requires regulatory waivers for stormwater management and buffer zone violations. While the Commission reached a consensus that the project provides overall ecological improvements, they had to engage in intense technical debate to ensure the legal 'rationale for decision' met the strict standards required to justify these impacts.
To protect our local resources, the Commission has mandated specific groundwater monitoring in the replication areas to ensure the project's impact on hydrology is managed. Residents should stay tuned as the implementation of these conditions and the long-term mitigation efforts move forward.
