The bond transaction to finance Cobb County's portion of the Atlanta Braves' new stadium closed last week after a yearlong delay arising from three Cobb residents' challenges to the bond validation.

Approval by the Cobb Board of Commissioners on Sept. 8 was the final step needed to close the Sept. 9 transaction for $376.6 million in AAA-rated taxable bonds. The fixed-rate, 30-year bonds are being issued by the Cobb-Marietta Coliseum & Exhibit Hall Authority.

The total cost for the new stadium, called SunTrust Park, is projected at $672 million. Cobb County will use $368 million of the $376.6 million bond issue to pay for its share of the stadium project, said James Pehrson, the comptroller for the Cobb County Office of Finance and Economic Development, in an announcement.
