Rockefeller Group Development Corporation built a 1.5 million-square-foot distribution center for General Mills in the City of Social Circle in Walton County, Georgia, 50 miles east of Atlanta. Work on the project began in spring 2009 and was  completed  in May 2010.

The new facility handles 167 trucks per day, 5,000 per month, to support the Southeast distribution operations of General Mills, one of the world's leading food companies. General Mills operates in over 100 countries and markets more than 100 consumer brands, including Cheerios, Häagen-Dazs, Nature Valley, Betty Crocker, Pillsbury, Green Giant, Old El Paso, and Progresso.

The building is the largest industrial one in the United States to earn LEED Gold certification, the second-highest designation a new building can receive from the US Green Building Council (USGBC). The building is also the second largest LEED Gold certified industrial building in the world.

RGDC and General Mills originally sought LEED-silver certification for the building. However, the number of credits accrued in five green design categories — sustainable sites, water efficiency, energy and atmosphere, materials and resources and indoor environmental quality — well exceeded the number of credits needed for LEED-silver.

RGDC  built the facility on a 130-acre site on East Hightower Trail, which is served by Georgia Railroad and CSX Intermodal, making the location ideal for distribution.

The building is 2,322 feet long, almost a half mile, with 8 rail doors alongside the railroad and storage capacity for 500 trailers. According to real estate research firm PPR, the facility is the largest build-to-suit distribution center begun in 2009. It includes more than 25,000 square feet of office space to accommodate administrative operations for the site. General Mills has the option to expand the building by 143,000 square feet to a total of more than 1.6 million square feet.

Key Sustainability Facts about the Social Circle Distribution Facility:

• Achieved a 48.9 % reduction in water use with low flow plumbing fixtures - reducing the building’s impact on local infrastructure and operation costs.
• Energy efficient light fixtures, occupant sensors, high efficient HVAC systems, roof mounted up-blast exhaust fans and wall louvers account for a 50.2% more energy efficient performance over typical industrial buildings, reducing the burden on the local power company and reducing operating costs for the facility.
• 33.88% of the materials used on the project were composed of pre-consumer and post-consumer recycled content. 
• 77.2% of the construction waste was diverted from landfills by sorting materials and sending them to the appropriate recycling centers. 
• 55.13% of the construction materials were extracted, processed or manufactured within 500 miles of the project site, helping support the local economy.
• Each area of the facility has at least 30% more outdoor air ventilation than normal. (Air quality is a key component of LEED certification.)
