These signs indicate the presence of a resource area protected under the Massachusetts Wetlands Protection Act and the Grafton Wetlands Protection Bylaw. Under the Bylaw, the Conservation Commission prohibits alteration and disturbance within twenty-five feet of resource areas. This area is called the no-disturb zone. As a condition of a Wetlands Permit, the Commission may require signage to ensure notification, recognition of, and respect for, resource area boundaries. These signs shall not be removed or relocated without written authorization from the Grafton Conservation Commission.
