Developments of Regional Impact

Mitigating the Impact of Large-Scale Developments

Under the Georgia Planning Act, any large-scale development, or one that is likely to impact neighboring jurisdictions, is subject to review as a Development of Regional Impact (DRI). ARC is responsible for conducting these reviews.

A DRI review is intended to foster communication and coordination between local governments and other relevant agencies and to provide a means of identifying and assessing potential impacts before conflicts arise.

A jurisdiction must submit information on potential DRIs to ARC for review and comment or risk losing Qualified Local Government (QLG) status with the Georgia Department of Community Affairs (DCA). Once submitted, ARC gathers input from neighboring jurisdictions and other potentially affected parties and produces a report detailing comments and recommendations. After the review is complete, the local government retains its authority to make the final decision regarding approval of the development.

GRTA DRI Reviews

Under state law, both ARC and Georgia Regional Transportation Authority (GRTA) are required to review DRIs. ARC provides staff support, under contract, to GRTA for the administration of that agency’s DRI reviews. The GRTA reviews focus on traffic impacts of proposed projects and potential mitigation measures. The agency’s focus and process are related to but distinct from those at ARC.

ARC administers the GRTA process according to GRTA’s existing Principles and Procedures for DRI Review and DRI Review Package Technical Guidelines, which remain in effect. GRTA continues to exercise executive oversight of its DRI process. GRTA also maintains authority and responsibility over its DRI Notices of Decision (NODs), including any conditions included therein.

This applies to reviews in all 13 counties in GRTA’s jurisdiction, which includes three counties outside ARC’s state-designated 10-county footprint. GRTA DRI reviews in these three counties (Coweta, Forsyth and Paulding), while administered by ARC, do not preempt or replace the DRI reviews performed by the regional commissions of which they are members.

DRI Pre-Review/GRTA Methodology Meeting

The pre-review meeting is an important initial step in determining whether a proposed development warrants regional review as a DRI. It is also typically combined with the GRTA DRI methodology meeting, in which assumptions for a GRTA-required traffic study are discussed and solidified.

Pre-review/methodology meetings are typically held on Monday afternoons at ARC, upon request from the host local government.
