Permits to Check Before Clearing Land in Merrimack
Alteration of Terrain. NH DES requires a permit when earth moving cumulatively disturbs more than 100,000 square feet over 10 years, or more than 50,000 square feet if any part is in protected shoreland (Env-Wq 1502.58 (opens in a new tab); RSA 485-A:17 (opens in a new tab)).
Wetlands. Excavating, removing or filling in wetlands and banks needs a state permit (RSA 482-A:3 (opens in a new tab)). Merrimack's zoning ordinance adds a Wetlands Conservation District and a Flood Hazard Conservation District, where grading, filling and excavation count as development (Town zoning ordinance (opens in a new tab)).
Intent to Cut. If clearing produces timber, the owner may need to file a notice of intent to cut with the town's assessing office before cutting (RSA 79:10 (opens in a new tab)). Land conversion cuts can be exempt up to set limits with the permits for the new use (RSA 79:1 (opens in a new tab)).
Confirm with Merrimack's Community Development and assessing offices for your parcel. This is general guidance, not legal advice.

How Much Does Land Clearing Cost in Merrimack?
HomeGuide (opens in a new tab) puts national land clearing averages at about $1,200 to $8,000 per acre: roughly $1,200 to $2,500 for light brush and small trees, $2,500 to $4,500 for moderate growth, and $4,500 to $8,000 for dense woods with large trees. Grading for a small home site is listed separately at about $2,000 to $5,000 on mostly level land and much more on rocky ground. These are national reference ranges, not our prices. Land clearing has too many variables for a calculator, so we price it after looking at the lot. If part of the job is brush or small trees, our forestry mulching cost calculator gives a rough starting point.
What changes the price here
- Tree size and density across the parcel
- Wetland or flood district limits on the clearing area
- Slopes on the lot
- Stump removal versus grinding in place
- Hauling distance and volume of logs and brush
- Grading and site prep after clearing
