One member expressed skepticism about the project’s feasibility, emphasizing the risks associated with extensive topographic changes. They highlighted the vulnerability of the site to erosion and environmental issues if left bare before adequate stormwater protection is in place. The commission explored alternative approaches that could preserve the site’s existing topography and minimize disruption. The conversation revealed a consensus on the need for a more formalized plan for phasing construction and implementing temporary erosion control measures.

Concerns about stormwater management were prominent, with discussions on how stormwater basins would interact and what stabilization protocols would be implemented during the construction process. The stormwater review team had raised issues regarding compliance with the town’s stormwater bylaw requirements. The commission suggested the engineering team revisit the plan to better address stormwater issues and maintain tree cover, which plays a role in safeguarding water quality.

The meeting also included a discussion on the proposed mapping initiative for vegetation management along Natick’s rail infrastructure. This involved mapping various spray application zones, with particular attention to areas near sensitive water bodies. The conversation identified “no application” zones where herbicide spraying is restricted and discussed the rationale for transitions between restricted and less restricted zones. Concerns about potential herbicide runoff into Beaver Dam Brook and other water bodies were addressed, resulting in a proposal to amend the spray zones to extend protection across certain areas.

In another agenda item, the commission reviewed a request for a certificate of compliance for a stormwater permit on Windermere Lane. The project, completed in 2023, featured a large rain garden that was functioning well, with no complaints from neighboring properties. A change in tree species due to the owner’s allergy was noted, but it did not affect the permit compliance. The motion to issue the certificate of compliance passed with one abstention.

The commission also considered a request for determination of applicability for Keolis, concerning vegetation management along the commuter rail line. The discussion focused on ensuring that the vegetation management plan adhered to local and state regulations while effectively managing growth near the rail line. The commission stressed the importance of maintaining clear communication regarding environmental protections and the management of vegetation in proximity to sensitive areas.

Additionally, a public comment session saw Rick Devereux, a resident of South Natick Hills, express concerns about extensive tree clearing and blasting activities associated with a local development project. Devereux sought clarity on the number of trees involved and the potential impact of blasting on nearby residences. He also raised questions about stormwater runoff implications, with the commission assuring him that addressing runoff is a critical part of their process.

The meeting also addressed the potential construction of a path along the railway corridor, which would avoid triggering Article 97 actions. Concerns about soil disturbance and testing for contaminants, particularly heavy metals, were discussed. The commission showed support for the project, contingent on further details being clarified, and considered applying for Community Preservation Act funds.
