Conservation Commission — March 31, 2026

**Lexington Conservation Commission — Meeting Recap, March 31, 2026**

The commission's March 31st meeting was largely routine, with unanimous votes across the board. But two issues are worth Lexington residents' continued attention.

**Eversource Herbicide Use in Wetland Areas:** Commissioner Tom Whelan raised a concern that Eversource is applying herbicides in utility easements that pass through wetland areas containing sensitive native plant species. This is not a new tension in conservation work — utility companies have maintenance obligations, but chemicals applied in or near wetlands can cause lasting ecological harm. The commission did not initiate any formal enforcement or regulatory process. Instead, Whelan was assigned to send staff a marked aerial map identifying the sensitive areas, with the apparent intent of communicating restrictions to Eversource. The scope of the issue — which wetland areas are affected, what chemicals are being used, and how frequently — was not quantified at the meeting. Residents living near utility easements and anyone who cares about Lexington's wetland health should watch for whether this leads to any formal, documented commitment from Eversource.

**After-the-Fact Amendments for Wetland Buffer Violations:** Two separate applications came before the commission seeking approval for construction that had already been built closer to wetland buffers than originally permitted. At 8 Blueberry Lane, a roof was built nearer to the wetland than the approved order allowed; the commission granted an amendment after confirming the applicant made corrections including roof trimming and restoration planting. At 560 Concord Avenue, a roof came in 190 square feet larger than approved and deck modifications were made without prior authorization; the commission continued that case to April 14th, pending an engineering review of stormwater calculations. Both cases may have legitimate explanations, but seeing the same pattern twice in one meeting is worth noting — particularly in terms of whether the amendment process functions as a genuine deterrent or a routine fallback.

**Other Actions:** The commission approved an order of conditions for an athletic field at 328 Lowell Street, which includes a 2,500 sq ft wetland replication area and native tree plantings (oaks strongly preferred; white pine explicitly excluded by the chair). Two new staff members were introduced: Assistant Conservation Director Evan Page and Regulatory Aide Mason Bunker, who will work 10 hours per week on regulatory compliance. The next regular meeting is April 14th; a site visit for 114 Wood Street is scheduled for April 21st at 6pm.
