The commission’s discussion on unauthorized construction centered on the lack of proper permitting and the notion of “permitting after the fact.” A member clearly articulated their objection to the practice, highlighting frustration over plans being treated as mere guidance rather than binding documents. Despite the deviations from the original plan, some members noted that certain modifications, such as repositioning a driveway to direct runoff away from a resource area, might have resulted in a net positive effect. However, there was a consensus on the need for a thorough evaluation of these changes to understand their impact on the environment.

The commission debated the merits of requiring additional shrub plantings to compensate for unapproved tree removals, preferring this approach over mandating the removal of unauthorized structures. They agreed to guide the applicant toward adding three to six shrubs, which would enhance the site’s ecological and aesthetic value.

Further discussion highlighted a reluctance to rush approvals without fully comprehending the implications of the unauthorized work. The commission decided to defer a final decision to allow the applicant time to consider the requested plantings and gather necessary documentation.

Attention then shifted to the contentious issue of dredging, with the commission addressing an enforcement order for dredging activities that had occurred without the necessary permits. The Massachusetts Department of Environmental Protection recommended a third-party peer review to assess the impact and suggested allowing the area to renaturalize. The commission explored the challenges of managing sediment disturbance and the potential for invasive species to return.

Members were divided on the value of conducting an underwater survey to assess the dredged area’s footprint and volume, with some voicing skepticism about its reliability and cost-effectiveness. The conversation pivoted to the importance of collaboration and community involvement, with public comments highlighting the need for a cohesive approach to lake management. Residents raised concerns about the feasibility of preventing motorboat traffic in certain areas and the implications of manual weed removal.

The meeting also covered the potential for collaboration with neighboring Westford to address invasive species through herbicide treatments. Discussions acknowledged past missteps in lake management and emphasized a non-punitive approach to rectifying these issues.

The commission proceeded to a public hearing regarding a septic system replacement on Worcester Drive. Updates were provided on the project’s approval by the Board of Health, including technical comments and waivers. The commission unanimously approved the motion to close the public hearing and issue an order of conditions.

The session concluded with an update on Littleton’s Tree City USA application, approved for the third consecutive year, underscoring ongoing efforts in environmental management. An administrative note highlighted upcoming discussions by the select board on docks on Lakeshore Drive, with a commitment to address these issues in future meetings.
