"Legislation allowing for the regional sales tax was created this year. The new law divides Georgia into 12 transportation districts, including one for metro Atlanta that takes in Cherokee, Clayton, Cobb, DeKalb, Douglas, Fayette, Fulton, Gwinnett, Henry and Rockdale counties. It provides for the tax to be imposed if approved within the district by a special referendum in 2012.
Transportation officials anticipate the 10-year tax will generate $16 billion, about one-tenth of what metro Atlanta needs to fix its traffic woes."
Various cities in the greater Atlanta area feel like they're being taxed to support transportation projects that won't benefit them, and are opposing the one-cent sales tax increase.
