At the July 16 Planning Board meeting, two major topics dominated the discussion: the impact of the Onyx Corporation project in Mason and upcoming shifts in Brookline's land-use regulations.
Regarding the Onyx Corporation excavation, the Board is focusing on protecting our local infrastructure and environment. Because the project is in a neighboring town, there is a risk to Brookline's roads and the water quality of Lake Potanipo. Board members discussed the need for enforceable conditions—such as dedicated road maintenance funds and mandatory water testing—rather than relying solely on a non-binding Memorandum of Understanding (MOU). The Board is currently coordinating with the Town Engineer and Mason officials to ensure these protections are real and enforceable.
Additionally, the Board is looking at significant updates to site plan regulations. This includes redefining 'frontage' to align with state changes regarding Class 6 roads and potentially revising how 'farming' and 'agriculture' are defined. These regulatory shifts will influence how future development and business operations are managed in Brookline. These items are slated for discussion in upcoming work sessions.
