When am I required to file an application with the Conservation Commission?

Under the Massachusetts Wetlands Protection Act Regulations (310 CMR 10.00) the Conservation Commission has statutory jurisdiction for activities within the Riverfront Area and within 100 foot buffer zone to wetlands including, but not limited to coastal and inland banks, swamps, and marshes. The Mashpee Conservation Commission also has jurisdiction within 100 feet of the 100 Year Flood-plain under the Town Wetland Bylaw, Chapter 172.

There are two kinds of applications under these regulations. For small projects 50 feet and greater away from wetland resources a Request for Determination of Applicability may be filed. Examples of small projects that may fall under this category could be the construction of decks, sheds, and native landscaping.

The second type of filing is the Notice of Intent filing which is for more complex projects such as construction of dwellings, removal of vegetation, regrading, and additions. These projects often require engineered plans showing the wetland resources on-site, abutter notification, and a public hearing.

Forms are available at the Conservation Commission’s Office and also online.
