Commission issues wetlands Order of Conditions for 40 Cobb St.; fence condition added

The Mansfield Conservation Commission on May 18 approved an Order of Conditions (DEP SE 211‑1029) allowing construction of a single‑family dwelling and driveway at 40 Cobb St., with specific limits on grading within the 50‑foot buffer to an intermittent stream associated with Back Bay Brook.

Conservation and Environmental Planner Katelyn Gonyer told commissioners that the proposed 38‑by‑26‑foot house would sit mostly outside the 50‑foot buffer and that only minor grading was proposed within it. The application originally showed a future 20‑by‑26‑foot addition; the applicant agreed to remove that future‑addition language from the plan so the Order of Conditions would not automatically authorize the expansion. "The only thing that may change is the fencing," the applicant noted during the discussion, and the commission added an explicit special condition allowing a chain‑link fence due to the applicant's family needs.

The commission attached a set of standard special conditions to the permit, including a record of order and plan of record, strict limits of work, erosion stabilization, pre‑construction notification, wetland flagging, an as‑built certification (COC) requirement, knotweed management, prohibition on dumping lawn clippings, restrictions on synthetic chemicals, and signage for the residential project. The added fencing condition was approved as part of the final motion. The motion passed unanimously, 5–0 (mover: Ryan O'Hara; seconder: Aaron Roth).
