Three Rivers Interlocal Council (TRIC)


Smart Growth & Regional Collaboration

The Three Rivers Interlocal Council (TRIC) is one of MAPC’s eight subregions comprised of thirteen communities located southwest of Boston: Canton, Dedham, Dover, Foxborough, Medfield, Milton, Needham, Norwood, Randolph, Sharon, Stoughton, Walpole, and Westwood.

TRIC gets its name from the three major rivers in the sub-region: the Neponset, Charles, and Canoe River. The mission of TRIC is to support cooperative municipal planning that links the impacts of growth and development in each town to aggregate impacts felt throughout the region. TRIC meets monthly to review and discuss issues of inter-municipal significance. Participants at TRIC meetings can include Local Council Representatives, town planners, members of Boards of Selectmen and Planning Boards, Town Administrators, Chambers of Commerce, and interested citizen-planners. All meetings and events are open to the general public.

First we heard from Mark Fine, MAPC's Director of Municipal Collaboration, about the regional collaboration work MAPC does on behalf of its communities. This work includes:

  • Serving as grant recipient for Massachusetts' four homeland security regions, managing grants from the U.S. Department of Homeland Security and the Massachusetts Executive Office of Public Safety and Security;
  • Operating a collective procurement program that contracts on behalf of its communities for public safety, fire, public works, highway, bicycle, and energy related equipment as well as public services; and
  • Facilitating collaborative projects between multiple municipalities as well as municipal efficiency projects. This work includes creating regional coalitions, helping communities contract for or provide services to one another, conducting community services and facilities analyses, and working with communities to create strategic plans.

We also heard from Amanda Chisholm, Chief Economic Development Planner at MAPC, who discussed current economic indicators for the TRIC region and MAPC's regional economic development work. This work includes:
