Subdivision Regulations

Subdivision regulations describe local requirements and limitations on how land may be subdivided. Subdivision regulations cover a wide variety of issues, including water supply and wastewater disposal. For groundwater protection, the regulations should ensure that on-site wastewater disposal systems (septic systems) and storm water infiltration structures do not contaminate groundwater.

For more information on alternatives for subdivision and site plan review regulations, contact your regional planning commission or the NH Office of Energy and Planning at 271-2155.
