The Cape Cod Commission is a regional planning authority and department of Barnstable County. It was created in 1990 by an Act of the Massachusetts General Court and confirmed by a majority of county voters.
In the wake of an unprecedented growth boom in the 1980s, the Cape Cod Commission Act found that the region known as Cape Cod (a geographic region largely co-extensive with Barnstable County) possesses unique natural, coastal, historical, cultural and other values which are threatened by uncoordinated or inappropriate uses of the region's land and other resources.
