The central focus of the meeting was the proposed installation of a transmission water main connecting the Smith Street Water Treatment Plant to the Crooked Springs Water Treatment Plant. Brian Sadowski of Aecom represented the Chelmsford Water District in presenting the project details, which are vital due to elevated levels of PFAS, a group of harmful chemicals detected in the water distribution system. The plan involves replacing existing pipes with an eight-inch water main along Smith Street, continuing with a new ten-inch main on Parkers Road, and using directional drilling techniques for specific sections to minimize disruption. The urgency of this project is underscored by recent EPA regulations, with public utilities required to meet strict PFAS limits by 2029.

Members of the commission queried the environmental impact of the extensive works, particularly concerning the Massachusetts Wetlands Protection Act. The project will affect various protected areas, including riverfront zones and flood-prone lands, although no direct impact on vegetated wetlands within the work limits was noted. Concerns about potential negative effects on the wetlands and surrounding ecosystems were raised, with assurances that best management practices like erosion control would be employed. The project is described as a limited project under Massachusetts regulations, with mitigation efforts to restore the area post-construction.

The commission acknowledged the need for thorough environmental assessments and documentation to ensure compliance with all relevant laws while addressing the need for clean water. A continuation of the hearing was approved to allow further input from the Department of Public Works (DPW) and address any additional concerns raised by community members.

Another topic was a proposed pollinator garden project, discussed by a certified Master Gardener, who outlined plans to cultivate native plant species to attract essential pollinators. The project seeks collaboration and funding sources, with suggestions to partner with local individuals offering plants for transplantation. The commission discussed the potential to involve community members, including local Master Gardeners, to support the garden’s development and monitor pollinator activity.

In addition, a project involving the installation of a lightweight walkway received attention. The design, using high-density polyethylene pipe, aims to provide a durable, elevated structure that minimizes environmental disruption. Volunteers played a role in its construction, with the commission noting positive feedback from users. This project is part of broader efforts to enhance accessibility and enjoyment of natural areas, despite some structures needing urgent repairs.

The meeting also addressed ongoing issues with property management and encroachments on conservation land. Urgency was expressed over potential encroachments near the Kouis property, with calls for a survey to clarify boundaries. Furthermore, concerns about invasive species management led to discussions on community training initiatives and securing resources for invasive control.

Public concerns were noted, especially regarding the Freeman Lake area and the installation of a dock that might encroach on conservation land. A survey was deemed necessary to resolve boundary uncertainties. The commission also discussed other ongoing projects, including new developments and compliance issues with property owners, highlighting the challenges of balancing development and conservation priorities.
