Locally-Based, Regionally-Driven Government  


TJCOG serves almost 2 million people in Chatham, Durham, Johnston, Lee, Moore, Orange, and Wake counties. The organization leads and coordinates a range of regional efforts that span across local boundaries, including transportation planning, development and land-use, housing affordability, water resource planning, disaster recovery and resilience, and economic development coordination. Additionally, the organization houses the Triangle J Area Agency on Aging, which oversees county aging initiatives and serves as a central source of information for older adults and their caregivers.

An Extension of Our Local Government Members

TJCOG is a local government by law, however we are also a member organization for our local governments and rely on both the support and engagement of those communities and staff for existence and relevance. As the needs of our members change, the services provided by TJCOG also change.

Who are our members?

Why Regional Government?

The challenges and opportunities faced by the local governments in the TJCOG region are often not unique to one community. Job access, transit modes, growing population, and aging residents are only a small few of the many issues that rely on a birds-eye and systemic perspective to ensure equity, accessibility, and a great quality of life for every resident in every local community.

Early Beginnings

TJCOG came into being during the creation of the Research Triangle Park in the late 1950's. Coordinated development was needed between the cities, towns, and counties surrounding the park, and the Research Triangle Regional Planning Commission was the entity to lead that coordination. Durham, Orange, and Wake counties; the cities of Durham and Raleigh; and the town of Chapel Hill joined together to form the organization and ensure strategic and going joint planning across the Triangle. 

Why the J? 

In 1970, the Councils of Government (COG) system that exists today across the state of North Carolina was created to more effectively administer services and funds from the federal and state governments to local municipalities. Each COG or region was identified by a letter of the alphabet (moving from west to east). The Research Triangle Regional Planning Commission was a natural fit to become Triangle J Council of Governments.
