The record, newest first

  1. Digital Realty's project page (undated, read on this date) described two buildings, about 212 MW initial IT load, roughly $3 billion including over $100 million of site cleanup, and a first phase due in early 2028. (Digital Realty, Oct. 30, 2026)

  2. Forest Park staff outlined a draft community-benefits package tied to a possible tax abatement for Digital Realty. (Soar Citizen Portal (AI-generated meeting summary), March 27, 2026)

  3. City staff recommended approval with buffer, wall and sound conditions for the 1.6 million and 200,000 sq ft buildings. (City of Forest Park Urban Design Review Board, July 18, 2025)

  4. Forest Park's design review board tabled concept approval for a two-building data center at 0 Fort Gillem; staff said the use is allowed by right. (City of Forest Park Urban Design Review Board, June 20, 2025)

  5. A regional-impact review (DRI 4482, 'ATL 15 and 16') was filed for the Forest Park site; Digital Realty told the AJC the 97-acre campus would total 1.9 million sq ft. (Georgia Department of Community Affairs, Oct. 30, 2026; Atlanta Journal-Constitution, June 2, 2025)

Conflicts and open questions

  • The Forest Park design-review documents do not name Digital Realty; they are linked here by location and the matching two-building layout.
  • The Digital Realty project page is undated; its source date is the day it was read.
  • The design-review outcome on July 18, 2025 was not found.
  • The design-review case covered a 47.19-acre parcel with buildings of 1.6 million and 200,000 sq ft (1.8 million total), slightly smaller than the 97 acres and 1.9 million sq ft Digital Realty describes.
  • The March 2026 Forest Park summary is an AI-generated meeting summary; Clayton County consent is needed to abate county taxes.
