Conservation Division Overview

The Conservation Division serves three primary purposes:

  • to administer and enforce state and local wetlands protection codes, as well as the state Stormwater Management Policy
  • to manage over 1,300 acres of town-owned conservation land and monitor conservation easements and restrictions
  • to conduct outreach and education regarding the town's natural resources and watersheds

Conservation Commission

The Conservation Commission serves to protect and preserve the natural resources of the town and to acquire land for conservation and recreation purposes. A major aspect of the Conservation Commission’s work is to protect the streams, rivers, and wetlands in Lexington by overseeing the permitting process for activities that may affect these areas. Learn more>>

Wetlands Protection

The Wetlands Protection Act (Massachusetts General Law Chapter 131, Section 40) prohibits any filling, excavation, or other alteration of the land surface or vegetation in wetlands, floodplains, or within 100 feet of wetlands, regardless of ownership, without a permit from the local Conservation Commission. Town rules (Chapter 130) also apply to activities that may impact wetlands.  Learn more about applying to do work within 100 feet of a wetland, 200 feet of a river or stream or area that may cause additional runoff>>

Conservation Land

Map labelled Interactive GIS MapsOver 1,300 acres--or approximately 12% of the town's area--have been protected in Lexington either as town-owned conservation lands or as conservation restrictions or easements.

Lexington Conservation Stewards

A dedicated team of volunteers, the Lexington Conservation Stewards are citizens who care for Lexington’s conservation land and other natural open space. Some attend work days to help build  boardwalks and restore meadows. Some carry a trash bag and pair of clippers with them when they go for a walk on one of our trails. Some apply for grants, help to design new trails, or help maintain our orchard at Cotton Farm. Whatever their level of involvement, Stewards are keeping an eye and a helping hand on our conservation land.

 A volunteer board, called the Steward Directors, oversees stewardship projects and reports to the Conservation Commission. The Steward Directors accept new members to this leadership body on a rolling basis. Joining is easy! Learn more>>
