The spending, the study said, will result in $116 million in tax revenues for the state, city, and county over the next 15 years, and in the creation of 2,100 new jobs between 2011, when construction is scheduled to be completed, and 2020.

The study also asserts that the new hall, a glass, steel, and white concrete structure dominated by two swooping "leaves," will become an iconic symbol of Atlanta, attracting tourists and "creative-class" workers.

"The city and state are working toward an energetic, vibrant future. We want to play our part," said ASO president Allison Vulgamore. "The Symphony Center is an essential project for the ASO's future, as worldÔ_class arts are essential for a worldÔ_class city. The partnership possibilities with education, business, arts, and tourism will strengthen all these areas as Atlanta and Georgia strive to create one of the great communities of the 21st century."

According to the Atlanta Journal-Constitution, the study, which cost the ASO more than $10,000, is part of the orchestra's efforts to secure public funding for the Symphony Center. The orchestra has raised $100 million, and is hoping to get $100 million from local governments. The cost of the building is estimated at $300 million.
