Ga. Code § 50-8-37
A regional commission shall review all applications of municipalities, counties, authorities, commissions, boards, or agencies within the area for a loan or grant from the United States, the state, or any agency thereof if review by a region-wide agency or body is required by federal or state law, rule, or regulation. In each case requiring review, the municipality, county, authority, commission, board, or agency shall, prior to submitting its application to the United States or state or agency thereof, transmit the same to the regional commission for its review. The comments of the regional commission shall then become a part of the application, to be appended thereto when finally submitted for the consideration of the United States, the state, or any agency thereof.
