Atlanta Regional Commission: Metro Planning and Government Coordination

The Atlanta Regional Commission (ARC) functions as the primary metropolitan planning organization and regional coordinating body for the 11-county Atlanta area, shaping decisions that cross city and county lines in ways no single municipality can address alone. This page covers ARC's definition, statutory role, operational mechanisms, the planning scenarios where it holds authority, and the boundaries separating its jurisdiction from those of individual local governments. Understanding ARC's function is essential context for anyone navigating Atlanta's regional governance landscape.

Definition and scope

The Atlanta Regional Commission is a state-created regional planning agency established under the Georgia Planning Act of 1989 (O.C.G.A. § 50-8-30 et seq.) and designated by the federal government as the Metropolitan Planning Organization (MPO) for the Atlanta urbanized area. As an MPO, ARC receives federal transportation funding authorization under 23 U.S.C. § 134, which mandates that urbanized areas with populations exceeding 50,000 maintain a designated MPO to qualify for federal surface transportation dollars.

ARC's 11-county planning region includes Cherokee, Clayton, Cobb, DeKalb, Douglas, Fayette, Forsyth, Fulton, Gwinnett, Henry, and Rockdale counties, along with the municipalities within those counties. The City of Atlanta sits at the core of this region but represents only one member jurisdiction among dozens. ARC's member governments collectively encompass a population exceeding 4 million people, making it one of the largest regional planning bodies in the southeastern United States (ARC, About the Atlanta Regional Commission).

Scope limitations and coverage boundaries: ARC's authority is advisory and coordinative, not regulatory in the traditional sense. ARC does not enact zoning ordinances, issue building permits, or levy taxes — those powers remain with individual cities and counties. Georgia state law governs the enabling framework; federal transportation law governs MPO functions. ARC's plans do not supersede local comprehensive plans but must be consistent with the regional plan for a local government to remain in good standing for state and federal funding eligibility. Jurisdictions outside the 11-county boundary — such as Barrow, Butts, or Spalding counties — are not covered by ARC's planning authority and fall under separate regional development centers. This page does not address those adjacent planning districts or ARC's activities related to the Atlanta Regional Workforce Development Board, which operates under separate federal workforce legislation.

How it works

ARC operates through three primary functional areas: transportation planning, land use and livability planning, and aging services administration.

Transportation Planning
As the federally designated MPO, ARC develops the following required documents:

  1. Regional Transportation Plan (RTP) — a long-range plan covering at least a 20-year horizon, updated every 4 years in the Atlanta nonattainment area, identifying capital and operational investments for roads, transit, freight, and active transportation (FHWA, Metropolitan Transportation Planning).
  2. Transportation Improvement Program (TIP) — a 4-year, fiscally constrained list of federally funded projects drawn from the RTP.
  3. Unified Planning Work Program (UPWP) — an annual document describing planning activities and budgets funded by federal metropolitan planning grants.

ARC's Policy Board, composed of elected officials and gubernatorial appointees from the member counties and cities, approves these documents. The Citizen Advisory Committee provides structured public input before Policy Board votes.

Land Use and Livability Planning
ARC administers the Regional Development Plan under the Georgia Planning Act, which requires each member local government to maintain a state-qualified comprehensive plan. Local governments submit their plans to ARC for regional review; ARC certifies whether they meet minimum standards. Municipalities and counties that fail to maintain qualified plans can lose eligibility for certain state funding programs administered through the Georgia Department of Community Affairs (Georgia DCA).

Aging Services
ARC serves as the Area Agency on Aging for a 10-county service area under the federal Older Americans Act (42 U.S.C. § 3001 et seq.), administering nutrition, transportation, caregiver support, and in-home assistance programs for residents aged 60 and older.

Common scenarios

Transportation project prioritization: When GDOT or MARTA seeks federal funding for a highway interchange, bus rapid transit corridor, or trail extension within the 11-county area, that project must appear in ARC's TIP to be eligible for federal dollars. Local governments lobby ARC's committees during update cycles to have their projects included — a process that intersects directly with Atlanta's Department of Transportation priorities and Atlanta's urban development initiatives.

Air quality conformity: The Atlanta region is classified as a nonattainment area under the National Ambient Air Quality Standards for ground-level ozone. ARC must certify that the RTP and TIP conform to the State Implementation Plan (SIP) approved by the U.S. EPA. Projects that do not demonstrate air quality conformity cannot receive federal highway or transit funding, giving ARC a structurally binding role even though it issues no direct regulatory orders.

Local comprehensive plan reviews: When a city like Roswell or Smyrna updates its comprehensive plan — particularly land use maps affecting density near regional corridors — ARC reviews the update for consistency with the Regional Development Plan. Comments from ARC can flag conflicts with regional housing or transportation goals, which matters for Atlanta's affordable housing policy discussions that spill across municipal lines.

Aging services delivery: A Fulton County resident aged 72 seeking meal delivery or home care support may be referred to a provider network contracted through ARC's aging services division, not through Atlanta city government, illustrating how ARC delivers direct services in parallel to municipal programs.

Decision boundaries

ARC's authority intersects with — but does not replace — the decision-making of individual governments. The distinctions below clarify where ARC leads and where it defers.

ARC decides:
- Whether a proposed transportation project appears in the federally required TIP and RTP
- Whether a local comprehensive plan meets minimum state qualification standards
- How federal Older Americans Act funds are allocated among service providers in the aging services area
- The technical methodologies used in regional travel demand modeling and air quality conformity analysis

ARC does not decide:
- Zoning classifications, density allowances, or site plan approvals — those belong to cities and counties (see Atlanta Zoning and Land Use)
- Which contractor wins a public works bid — that remains with the procuring government (see Atlanta Government Contracts and Procurement)
- The City of Atlanta's capital budget — that process runs through the Mayor's Office and City Council (see Atlanta City Budget Process)
- Tax rates or fee structures for any member jurisdiction (see Atlanta Taxes and Fees)

A critical contrast exists between ARC's MPO role and the Georgia Regional Transportation Authority (GRTA). GRTA holds state-granted powers to operate express bus service and, under certain conditions, to impose development restrictions near regionally significant transportation facilities — actual regulatory authority that ARC does not possess. ARC plans; GRTA can act. Both are referenced in the Atlanta State and Federal Government Relations context, but they are structurally distinct bodies.

The Atlanta Metro Authority home provides a broader orientation to the regional governance landscape within which ARC operates alongside city and county bodies.
