A small group of people marched into the Cobb Commissioners’ office Friday, hoping for answers on the stadium deal.

“We’re here to deliver to our board of commissioners a copy of a letter in which we presented them a number of questions,” said Ben Williams, president of the Cobb County Chapter of the Southern Christian Leadership Conference (SCLC), one of a dozen people crowded into the reception chamber.

“Our research into the financial projections shows there are too many gaps,” said protest leader Rich Pellegrino. “It’s based on hyperbole and not fact.”

The stadium deal was approved by Cobb commissioners in a 4-1 vote last month, paving the way for a $672 million stadium at I-285 and I-75. Braves executives also plan to surround the stadium with a $400 million business, residential and entertainment complex designed to bring in revenue even in the off season.

Pellegrino said questions center on the true cost of the new stadium and about how the deal came about.

“Anytime there’s lack of transparency, that’s the suspicion – that there’s corruption,” he said.

The letter gives county commissioners two weeks to answer. If they choose not too – or if the answers are not satisfactory to Pellegrino and his group, the activists threaten to push for an ethics investigation or file a lawsuit, or both.

County spokesman Robert Quigley said commissioners have not yet seen the letter and will respond appropriately when they do.
