Subdivision Approval

DES must review all applications and plans for subdivisions, and issue an “Approval for Subdivision” before any structures from which wastewater will be discharged are built or before other site alteration activity specific to the proposed subdivision commences. In addition, subdivided lots or units may not be sold, leased or rented until DES issues an Approval.

Purpose
The subdivision of real property requires a review by DES to ensure that each resulting parcel or unit supports the long-term wastewater absorption requirements without causing environmental damage, overload, or a public health risk.

Applicability
Pursuant to RSA 485-A:29, I, Water Pollution and Waste Disposal/Submission and Approval of Plans and Specifications, DES regulates the subdivision of land into two or more lots if the proposed lots will not be served by municipal sewers and one (or more) of the proposed lots is less than five acres. Subdivision approval is required for lots under 5 acres, leased land, campgrounds and condominium creation; for both residential and commercial developments where septic systems are, or will be used.
