At the May 2 Planning Board site walk, officials reviewed Onyx Corp.’s phased excavation plan, which includes significant terrain removal and road grading near the Campbell Mill Rd. and Brookline Rd. intersection.
Two specific points from the meeting warrant community attention. First, Board member Chris Jones noted that the Board is willing to consider waivers for the 3-acre maximum limit per project phase, provided Onyx Corp. gives "sufficient justification." This indicates the Board may be open to allowing larger-scale construction phases than current regulations typically permit.
Second, the scale of the excavation has raised direct questions regarding environmental mitigation. While Onyx Corp. representatives expressed a willingness to pave the secondary access road to reduce impacts, the Board and residents discussed ongoing concerns regarding dust, noise, and the potential risk to neighboring well and septic systems (specifically mentioning the proximity to abutter Dillon Conner's property).
As this project progresses, residents should stay informed on whether these waivers are sought and what specific, enforceable protections will be required to safeguard local infrastructure and neighbors' water supplies.
