Westplan's yet-to-be-named development calls for 310 apartments, a 200-room hotel, 65,000 square feet of office space, and 11,000 square feet of retail.
Westplan Investors earlier this month presented plans to City of Smyrna to erect a mixed-use development in Cumberland near SunTrust Park and The Battery Atlanta totaling more than 525,000 square feet.
The Cobb County Courier first reported the plans.
The 8.7-acre site at 2800 / 2810 Spring Road is currently home to a strip mall and the Emerson Center.
Westplan purchased the site in May for $7.2 million.
The yet-to-be-named project calls for 310 apartments, a 200-room hotel, 65,000 square feet of office space, and 11,000 square feet of retail.
The project, which has been tabled to a vote in September by the Smyrna planning and zoning board, would involve annexing 5.9 acres into Smyrna from unincorporated Cobb.
Westplan's mixed-use development would be the fourth major project in that immediate area adding to Cumberland Mall, Cobb Galleria and SunTrust Park/The Battery Atlanta.
If approved, the project would break ground early 2018 with an expected grand opening in 2020.
