The Braves want the new stadium in Cobb County to be environmentally friendly. 

Mike Plant, Braves' executive vice-president of business operations, tells the Marietta Daily Journal, construction plans call for a 30,000 gallon irrigation tank under the field. 

Water pooling on the field during heavy rains will be sucked through a filtration system into a storage tank and reused for irrigation later. 

Plant also says the Braves intend to utilize energy efficient lighting at the ballpark.  The Braves want the stadium to be a Leadership in Energy and Environmental Design (LEED) certified building.

AT&T Park in San Francisco & Marlins Park in Florida are both LEED-certified, according to mlb.greensports.org. 

Construction on the stadium continues.  Plant says the concrete caissons needed for the foundation of the stadium are nearly complete.  Two additional rigs were brought in for the drilling to keep the project on schedule.
