Connecticut’s nine planning regions are the geographic subdivisions that took over the coordinating role counties play in other states. Each region is run by a Council of Governments made up of the chief elected officials of its member towns, and together they handle regional planning, transportation funding, and shared services across the state’s 169 municipalities. Connecticut is the only state that fully abolished county government, a change that took effect on October 1, 1960.
What Replaced Connecticut’s Counties
Connecticut’s eight original counties dated to 1785, but by the mid-twentieth century they had become administrative shells. Real political power sat with the state and the towns. By the time the General Assembly acted through Public Act 152 in the 1959 session, the counties’ main remaining job was running jails, with smaller duties covering courthouse buildings, weights and measures, road disputes, and certain trust funds. The state absorbed those functions and rolled the small county workforce into state civil service.1Connecticut General Assembly. County Government Abolishment
The eight legacy names — Fairfield, Hartford, Litchfield, Middlesex, New Haven, New London, Tolland, and Windham — still appear on mail and in daily conversation, but they carry no governmental authority. In their place, the state designated planning regions whose boundaries follow how people actually live, work, and commute.
The Nine Planning Regions
The Office of Policy and Management designates the state’s planning regions under Connecticut General Statutes Section 16a-4a.2Justia. Connecticut Code 16a-4a – Office of Policy and Management. Duties and Powers There are nine of them:
- Capitol Region, covering the Hartford metropolitan area and surrounding towns
- Greater Bridgeport, along the southwestern coast
- Lower Connecticut River Valley, around Middletown and the river shoreline
- Naugatuck Valley, the corridor around Waterbury
- Northeastern Connecticut, rural towns in the state’s northeast corner
- Northwest Hills, in the northwest
- South Central Connecticut, the New Haven metropolitan area
- Southeastern Connecticut, along the coast near New London
- Western Connecticut, around Danbury and the panhandle near New York
The boundaries reflect economic ties, transportation corridors, natural features, and demographic patterns rather than the old county lines.3U.S. Bureau of Labor Statistics. New 2024 Connecticut Counties
How the Regions Are Governed
Each planning region is run by a Council of Governments, or COG, established under Chapter 127 of the Connecticut General Statutes. The governing body of every COG is composed of the chief elected officials of its member municipalities. That means mayors and first selectpersons sit at the table, so the people making regional decisions answer directly to local voters.
COGs can accept federal and state grants, enter into service agreements with member towns, and take on programs that other states hand to counties. A town can contract with its COG to deliver any service the town is authorized to perform on its own, and the COG can pass authority down to smaller groups of towns when that makes sense.4Connecticut General Assembly. Connecticut Code Chapter 127 – Regional Councils of Governments
Day-to-day work is handled by professional staff under an executive director appointed by the council. Staff bring expertise in transportation planning, land use, economic development, emergency preparedness, and geographic information systems. For smaller towns that can’t afford a full-time planner or engineer, COG staff effectively function as an extension of the municipal government.
What Planning Regions Actually Do
Regional Planning and Land Use
Each COG must prepare a Regional Plan of Conservation and Development at least once every ten years, covering land use, housing, highways, parks, schools, utilities, agriculture, and environmental protection. Regions along Long Island Sound must also address water quality and pollution reduction.5Connecticut General Assembly. Connecticut Code Chapter 127 – Regional Councils of Governments
When a town updates its own Plan of Conservation and Development, it submits the update to the COG, which issues an advisory report on how the town’s plan lines up with regional, state, and neighboring plans. Advisory is the operative word. The General Assembly has made clear that a COG referral cannot override a local land use decision. Towns keep full zoning authority.
Transportation and Federal Funds
Several COGs also serve as Metropolitan Planning Organizations, the federally mandated bodies that program federal highway and transit dollars within designated metropolitan areas.6Naugatuck Valley Council of Governments.

Funding – MetroCOG For a state with 169 small municipalities, this keeps every town from independently lobbying for road money.
Shared Services
The statute authorizes 25 categories of regional services, including engineering, animal control, public safety, emergency management, health, housing, recycling, household hazardous waste collection, fire protection, and solid waste disposal.4Connecticut General Assembly. Connecticut Code Chapter 127 – Regional Councils of Governments In practice, some COGs run regional animal control so small towns don’t each need a shelter and officer. Others coordinate group purchasing, share specialty public works equipment, or provide contract planning services to towns without their own planning office.
How Planning Regions Are Funded
COGs draw revenue from state appropriations, federal grants, and municipal dues. The main state vehicle is the Regional Planning Incentive Account. Starting with the fiscal year ending June 30, 2024, that account distributes seven million dollars a year to the nine COGs through a formula that combines a base payment with a per capita amount tied to the most recent census. OPM develops the formula in consultation with the COGs and reviews it every five years.8FindLaw. Connecticut General Statutes 4-66k
Federal transportation planning funds add another significant revenue stream for the COGs that serve as Metropolitan Planning Organizations. Member towns pay annual dues under formulas set by each COG’s bylaws, and COGs can charge for contract services like planning assistance and engineering support.
Federal Recognition as County Equivalents
In 2022, the U.S. Census Bureau adopted Connecticut’s nine planning regions as county-equivalent geographic units, replacing the eight legacy counties.9U.S. Census Bureau. Change to County-Equivalents in the State of Connecticut for 2022 ACS Census data products starting with the 2022 American Community Survey use the new boundaries, and by 2024 all Census Bureau operations and publications reflect the nine planning regions rather than the old counties.
The shift matters beyond mapmaking. Federal agencies now track demographics, economic trends, and labor statistics using the planning region boundaries.3U.S. Bureau of Labor Statistics. New 2024 Connecticut Counties When federal grants and formula funding are distributed on a per-county basis, Connecticut’s planning regions qualify the same way counties do elsewhere.10Federal Register.
