What the Conservation Commission Does
The Lexington Conservation Commission was established in 1963 when Town Meeting voted to accept the Conservation Act (M.G.L. Chapter 40 51 and s. 8c), which had been passed by the Massachusetts legislature to promote and protect open space in the Commonwealth. The Commission's responsibilities were expanded to include administration and enforcement of wetlands protection when the Wetlands Protection Act(M.G.L. 131 Section 40) was created.
A major aspect of the Commission's work is overseeing the conditions under which work may be done that affects a river, stream or wetland in Lexington. Anyone seeking to work within 100 feet of a wetland, 200 feet of a river or stream, or in any area that may cause additional runoff into a wetland, river, or stream must obtain prior approval of the Commission. In order to get that approval, applicants must file under one of the two following procedures:
- Request for Determination of Applicability
- Notice of Intent/Abbreviated Notice of Intent

The Conservation Commission may also, in the name of the town, acquire land, easements, conservation restrictions or other contractual rights as necessary to maintain, improve, limit the future use of, conserve, and properly utilize open space areas and manage the same. There are a total of more than 1,300 acres of town-owned conservation land in Lexington. Many other wetland areas under private ownership are protected by conservation easements or conservation restrictions on development.
Endangered species protection falls under the jurisdiction of the state National Heritage and Endangered Species Program (NHESP). Any proposed work in both wetland and upland areas that will alter habitat for endangered and rare species must go through an NHESP permitting process.
