The Cape Cod Commission is charged with recommending the designation of Districts of Critical Planning Concern, or DCPCs. A DCPC is a powerful planning tool that allows a town or a group of towns to impose a moratorium — a "time out" — on certain types of development or activities in a specified area to plan for and adopt special rules and regulations that will protect natural, coastal, scientific, cultural, architectural, archaeological, historic, economic, or recreational resources or values of regional, statewide, or national significance.

DCPC Process

Districts of Critical Planning Concern are generally nominated by a town or several towns, although they may also be nominated by the Cape Cod Commission itself and by two bodies of Barnstable County regional government: the Barnstable County Commissioners (the executive branch) and the Barnstable County Assembly of Delegates (the legislative branch).

Once nominated, a moratorium on certain development or types of activities may go into effect in the specified area. If accepted for consideration, the proposal undergoes an extensive public hearing process conducted by the Cape Cod Commission.

Upon consideration of the nomination materials and all public testimony, the Cape Cod Commission then decides whether to recommend a nominated district for DCPC designation by the Assembly of Delegates and the County Commissioners. If a district is ultimately approved by these bodies, the rules — known as "implementing regulations" — that the nominating communities create to promote the purposes for which the DCPC was designated then govern development in the designated DCPC area.

To date, Barnstable County has designated 12 Districts of Critical Planning Concern that were nominated by their respective towns, the County Commissioners, or the Cape Cod Commission.

  • Centerville Village Center/Craigville Beach DCPC—Designated in May 2008 to protect 380 acres of land in two separate areas, Centerville Village Center and the Craigville Beach area, from inappropriate development that threatened historic and scenic character as well as flood hazard protections and water quality concerns. The Centerville Village Center DCPC was designated to support the small-scale economy of the village center and protect its historic resources. The Craigville Beach DCPC was designated to enhance flood hazard protections along the barrier beach, protect views to Nantucket Sound, and moderate the scale of new development to preserve historic resources and limit water quality impacts to the Centerville River and nearby ponds. Implementing Regulations were adopted by the Cape Cod Commission and the Barnstable County Assembly of Delegates, and were added to the town’s zoning regulations in July 2009 (Centerville Village District) and January 2011 (Craigville Beach District).

  • Ocean Management Planning DCPC (Cape-wide)—Designated in April 2010 in an effort to plan for development in Cape Cod's ocean water, this was the first Cape-wide DCPC. The County Commissioners made the nomination in December 2009 in anticipation of the final Massachusetts Ocean Management Plan on December 31, 2009. The designated DCPC included all the ocean waters and land below and air above within Barnstable County, starting from a line drawn 0.3 nautical miles seaward from Mean High Water (MHW) around Barnstable County and extending to 3 nautical miles from MHW, or the state jurisdictional boundary.
    Ordinance establishing the DCPC: Barnstable County Ordinance 10-03
  • Fertilizer Management DCPC (Cape-wide)—Designated in 2013 to protect water quality and educate residents on Best Management Practices for fertilizer application. This second Cape-wide DCPC was the first one nominated by the Cape Cod Commission itself. The Commission proposed the Cape-wide DCPC in response to state legislation that would remove the ability of individual communities to regulate fertilizers. The Cape Cod Commission subsequently worked with towns and stakeholders to develop the DCPC "implementing regulations." 
    Ordinance establishing the DCPC: Barnstable County Ordinance 13-07
  • Eastham DCPCDesignated in 2017 to guide economic development in the town's commercial areas, encourage mixed use development, and improve safety along the Route 6 corridor.
