The alteration of terrain permit program is intended to protect New Hampshire surface waters by controlling soil erosion and managing stormwater runoff from developed areas. A permit is required whenever a project proposes to disturb more than 100,000 square feet of terrain (50,000 sf if within the protected shoreland). 

The program applies to both earth moving operations, such as gravel pits, as well as industrial, commercial and residential developments. 

Permits are issued by DES after a technical review of plans and documentation submitted with an application and the appropriate fee. DES personnel are available to discuss proposed projects on a preliminary basis prior to submission of the application so as to assure compliance with the program.
