Docks and Piers

Docks and Piers

Prior to building a dock, proposals must be approved by the Conservation Commission by filing a Notice of Intent (see WPA Form 3, also located in 'Forms Filing Procedures, and Fees'.) 

If any activity is located within shellfish habitat or other Priority Wildlife Habitat, property owners must also file for a Massachusetts Endangered Species Act (MESA) review prior to any construction.

Once an Order of Conditions (permit) is issued by the Conservation Commission, the Harbormaster may issue a yearly permit for seasonal and/or floating docks. However, the Massachusetts Department of Environmental Protection (MassDEP) issues licenses for docks with pilings (Chapter 91 license).

Please note:

  • The intent of the Commission is to have the size of all Piers be as small as possible to avoid or Minimize Adverse Effects and cumulative adverse effects upon the wetland values.
  • The purpose of a dock is only to provide safe access to a watercraft.
  • Massachusetts Department of Environmental Protection (MassDEP) strictly forbids covered docks, floating sheds, gazebos, and seating areas on docks.
  • A dock / pier should be at least 3 feet wide, but no more than 4 feet wide, and should extend only to a point that provides a safe berthing.
  • Your dock cannot impede the ability for others to swim or navigate their watercraft easily and safely.
  • Planks should be spaced at least 3/4 inch apart to permit light filtration to protected wetland plants, including eelgrass.
  • The use of CCA (Copper Chromated Arsenic) pressure treated wood is toxic to both humans and wildlife and is strictly forbidden. There are safer pressure treated wood alternatives that do not contain CCA that are approved by the EPA.
