Cobb MSPLOST Referendum Project List Approved by ATL, Proceeding to BOC Vote

On Thursday, June 6th, 2024, the Atlanta Transit Link (ATL) Authority unanimously approved Cobb County DOT’s narrowed-down list of projects for its potential Mobility SPLOST (MSPLOST) referendum. The larger list of Cobb’s projects were amended into the ARTP on April 4th per the ATL’s HB930 process. Yesterday’s final approval now allows the Cobb County Board of Commissioners to vote on whether to place a Mobility SPLOST referendum on the November 2024 ballot, which, if passed, would fund the narrowed-down list of mobility projects.

During the ATL meeting, an ATL staff presentation covered important criteria for Cobb’s projects in context of the ATL review process: 1) Consideration of Approved or In-Progress Projects in Neighboring Counties, and 2) Consideration of Additional Federal or State Funding. The numbers show that of the $14.5 billion estimated cost over 30 years, 21% will come from federal or state funding. The remaining $10.9 billion would come from MSPLOST revenue. The ATL Staff  found that Cobb’s Project List meets “the statutory criteria outlined in OCGA § 48-8-269.45(C)” and recommended that the ATL board approve the list.
