Construction crews are working on a 31.1-acre site in Stone Mountain, Georgia to build a new mixed-use development called Mountain Marketplace. The project, led by Fuqua Development, will feature a Costco store exceeding 150,000 square feet as the anchor tenant, along with other retail like Chick-fil-A and Whataburger, a community park, and a 248-unit residential development by Greystar.

Why it matters

The development will revitalize the former site of the Stone Mountain Tennis Center, which served as an Olympic venue during the 1996 Atlanta Games but has been closed and demolished since 2007. The new project aims to bring new commercial and residential options to the area along the DeKalb-Gwinnett county border.

The details

The Mountain Marketplace development will include a 150,000+ square foot Costco store as the anchor tenant, along with other retail like Chick-fil-A, Whataburger, and a bank. Greystar is also building a 248-unit residential development called Flats at Mountain Marketplace on six acres of the site. The project will feature 1.12 acres of community greenspace and a 10-foot-wide multi-use path.

  • The tennis center was closed in 2007 and demolished in 2018.
  • Gwinnett County's Board of Commissioners approved the sale of the site to Fuqua Development in 2024.
  • Construction on the Mountain Marketplace development is currently underway.
  • The Costco store is expected to open in late 2026.
