Any activity proposed within a wetland resource area or its buffer zone must be reviewed by the Conservation Commission and receive a permit for the work unless noted as an exempt activity in the Tewksbury Wetland Bylaw or State Wetlands Protection Act. Examples of wetland resource areas include - rivers, streams (perennial or intermittent), riverfront areas (land within 200 feet of a river or perennial stream), flood plains, vernal pools and freshwater wetlands like swamps and marshes. If you are unsure whether your property is within a wetland area or buffer zone, please contact the Conservation Agent.

Permit Applications

The three types of permit applications that are filed with the Conservation Commission are described below:

Request for Determination of Applicability (RDA): This application is generally meant for minor projects within the buffer zone that will have no impact on a wetland resource area. 

Notice of Intent (NOI): This application is generally meant for projects involving significant work in the buffer zone or any work proposed within the wetland resource area. 

Abbreviated Notice of Resource Area Delineation (ANRAD): This application is generally filed to have the Conservation Commission confirm the boundaries of various wetland resource areas (e.g., bordering vegetated wetlands, Bank of a stream, etc.) within a project site. ANRAD applications do not propose any construction activities; however, the application can indicate whether the ANRAD being filed is associated with a single-family home.
