Inner Core Committee (ICC)

Inner Core Committee map screenshotThe Inner Core Committee (ICC) consists of 21 cities and towns within the metropolitan Boston area. ICC emerged as a forum through which issues of mutual concern could be explored and joint and cooperative action fostered. Communities in the ICC region are among the most urban and populous within the MAPC planning area and deal with a host of unique challenges. The ICC is also MAPC’s largest subregion, representing the largest number of municipalities of any subregion, about 51% of the MAPC region’s population – over 1.6 million residents.

The ICC consists of representatives from twenty-one of the metropolitan area’s innermost communities: Arlington, Belmont, Boston, Brookline, Cambridge, Chelsea, Everett, Lynn, Malden, Medford, Melrose, Milton,* Needham*, Newton, Quincy, Revere, Saugus, Somerville, Waltham, Watertown and Winthrop. The Boston Redevelopment Authority and the Metropolitan Area Planning Council are also voting members of the Committee.

*Milton and Needham have dual membership in ICC and the Three Rivers Interlocal Council (TRIC).

See below for information on Inner Core communities, upcoming meetings, and Inner Core Committee documents, and contact information.


Inner Core Committee meetings are open to the public; non-members and representatives of neighboring municipalities are also encouraged to attend ICC meetings. In addition to ICC membership, many Inner Core communities are represented in other groups convened by MAPC, including the MAPC Council and the Metro Mayors Coalition.

Starting in September 2014, the Inner Core will meet on the second Thursday of every other month. View our FY15 Work Plan.

The ICC newsletter is the best way to stay updated; contact Jenn Erickson to be added to the email list.
