In Connecticut, councils of governments, also known as COGs, are regional planning organizations that bring together the chief elected officials or professional managers from member municipalities in Connecticut. Since 2015 and 2022, the Connecticut planning regions served by COGs have been recognized as county equivalents under state and federal law respectively, superseding the eight legacy counties in the state for most federal funding and statistical purposes.
The COGs are meant to aid coordination among neighboring cities and towns, and between the towns and the state government, on issues including land use, zoning, and transportation. They serve some functions analogous to county governments in other states, but have no independent taxing authority (Connecticut disbanded county governments in 1960). Councils of government also host some intermunicipal services based on the needs and voluntary participation of member or client municipalities. Councils, or COGs, receive funding through membership dues, state grants, and federal grants.
