Consultant says unpermitted culvert and clearing altered wetlands at 86 Lynwood Street; commission schedules site-flagging and continuation

Charles Karen of Karen Environmental Consulting told the Gardner Conservation Commission that a desktop review and aerial imagery indicate substantial clearing on the Duffy property at 86 Lynwood Street beginning around 2018–2019, accompanied by regrading and a newly installed culvert. Karen said those changes appear to have altered setbacks and buffer areas and in some places involve rock armoring or a “jetty” adjacent to a small pond and vegetated wetlands.

The presenter recommended soil sampling, physical flagging of resource boundaries, removal or rearrangement of rock armoring, plantings (winterberry, highbush blueberry) and stabilization of disturbed slopes. Karen said the culvert is a change in the site's hydrologic flow and that the team needs to flag the location precisely before preparing a restoration or site plan — and noted a licensed civil/river engineer (Chris Scott) can prepare a formal site plan if required.

The property owner described using a larger pipe and placing crushed stone under what he called a failing pond outlet; he said his intent was maintenance and beekeeping rather than disturbance. Commissioners and staff stressed that a distinction must be made between historical disturbance and new, unpermitted alteration; they recommended treating the resource area conservatively (worst-case perennial mapping) because drought conditions complicate field verification. The commission agreed to ask the owner to flag the suspected boundaries, to arrange a group site visit after flagging, and to continue the hearing to June 9 to allow surveys and a restoration plan to be prepared.

The commission emphasized that restoration work should minimize additional disturbance and include erosion controls, and said it expects a clearer, data-rich engineering presentation before any final determination.
