Rules to Check Before Mulching in Derry
Mulching brush on an upland back lot usually needs no permit. Water and wetlands are where the rules come in.
Protected shoreland. Under RSA 483-B:9 (opens in a new tab), the woodland buffer covers protected shoreland within 150 feet of the reference line, and at least 25 percent of the area between 50 and 150 feet must be kept as natural woodland. Inside the first 50 feet, stumps and roots must stay in the ground. Mulching that would cut into those areas should be planned with NHDES rules in mind.
Wetlands. RSA 482-A:3 (opens in a new tab) requires a state permit to excavate, remove or fill in banks, marshes and swamps, and Derry's Wetlands Conservation Overlay District (opens in a new tab) adds local limits, including a 150-foot buffer around prime wetlands.
Steep slopes near water. NHDES lists disturbance of slopes of 25% or steeper within 50 feet of surface water as an Alteration of Terrain (opens in a new tab) trigger.
This is general guidance, not legal advice. Confirm with the Town of Derry or NHDES for your parcel, and we will point out anything on site that raises a permit question.
