Permits and Utility Rules for Stump Grinding in Derry
Most backyard stump grinding in Derry needs no permit. Two situations deserve a check first.
Waterfront lots. Under the Shoreland Water Quality Protection Act, RSA 483-B:9 (opens in a new tab), stumps and their root systems inside the 50-foot waterfront buffer must be left intact unless removal is approved by NHDES or done for runoff control or planting, and removed stumps must be replaced with pervious surfaces or new woody vegetation. Lots on Beaver Lake, Big Island Pond and other public waters should be measured before any grinding.
Digging near utilities. New Hampshire's damage prevention law, RSA 374:51 (opens in a new tab), requires premarking the work area in white and notifying Dig Safe at least 72 hours ahead, not counting weekends and legal holidays.
If a stump sits in or near a wetland or stream bank, RSA 482-A:3 (opens in a new tab) may require a state wetlands permit. This is general guidance, not legal advice. When we see a permit question on your property, we will point it out so you can confirm with the Town of Derry or NHDES.
