Conservation Commission: July 28, 2026

The Chelmsford Conservation Commission meeting on July 28, 2026, primarily focused on environmental concerns related to a recent aquatic herbicide treatment in Freeman Lake. Residents raised issues about potential damage to the native pickerweed population following the application of diquat, a herbicide used to control invasive aquatic plants. Water and Wetland, the contractor responsible for the treatment, presented evidence and expert testimony asserting that the treatment was conducted in compliance with all regulations and that the herbicide should not have affected the pickerweed. The commission discussed options including monitoring the situation over the next 30 days, requiring an independent third-party survey at the applicant's expense, or issuing enforcement orders if necessary. Additionally, the commission addressed procedural matters such as continuing regulatory hearings, requiring site compliance monitoring for a major construction project, and approving meeting minutes. The discussion also included plans to develop informational materials for new homeowners about wetlands regulations and updates on local land management and volunteer activities. No contract awards or new procurement actions were reported, but the commission indicated intentions to draft an RFP for site compliance monitoring related to ongoing construction projects.
