CT Planning Regions

Published by State of Connecticut | State of Connecticut | Metadata Last Checked: November 14, 2025 | Last Modified: 2025-01-08
This CT Planning Regions layer consists of individual polygons representing each of the 9 planning regions that make up the state of Connecticut. This feature layer is directly derived from the CTDOT Municipalities feature layer geometry, created by CT Department of Transportation. The municipalities are dissolved into their associated regional Councils of Governments. This feature layer includes US Census Federal Information Processing Standards (FIPS) codes that are associated with each municipality. This was included based on information from Connecticut County to County Subdivision Crosswalk from the US Census. Connecticut’s 9 planning regions provide a geographic framework within which municipalities can jointly address common interests and coordinate such interests with state plans and programs.  CGS Section 16a-4a authorizes the Secretary of the Office of Policy and Management (OPM) to designate or redesignate the boundaries of logical planning regions. CGS Section 4-124j authorizes the member municipalities of each planning region to establish a formal regional governance structure known as a council of governments (COG). These regions have been recognized as county-equivalents and supersede the eight legacy counties in the state.
