NASHVILLE — Plans to construct a major data center campus adjacent to the Nashville Zoo have sparked an unusual and intense local debate, pitting economic development interests against environmental and community concerns. The proposed facility, to be built less than 320 feet from the zoo’s habitat for clouded leopards, a vulnerable species, has drawn bipartisan criticism and prompted a temporary halt on similar developments in the Nashville area.

The permit application for the data center by DC BLOX, an Atlanta-based company, was filed earlier this month for a 69,000-square-foot building designed to supply 10 megawatts of power for computational use. The facility would replace a much smaller, roughly 2,000-square-foot data center on the same site, which had supported a call center previously operating there. DC BLOX also plans a second, significantly larger building of at least 261,000 square feet, projected to deliver 40 megawatts of power. The entire campus is expected to cost at least $700 million.

The announcement has stirred broad opposition, including from Tennessee country singer Brad Paisley, who called the plan “an absolute nightmare scenario,” and Senator Marsha Blackburn, the Republican gubernatorial front-runner, who urged reconsideration of the project's location due to the zoo’s status as a vital educational and economic asset. Nashville Mayor Freddie O’Connell later backed a temporary moratorium on new large data center approvals in the region, citing concerns raised during a planning commission meeting that drew a large, impassioned crowd.

Local officials, environmental advocates, and community members have expressed unease about potential negative effects on the zoo's animals, particularly the clouded leopards that have been a focal point of the facility’s conservation program. Since 1991, the zoo has welcomed 51 cubs of this elusive species, including a recent 12-week-old cub named Azi, born close to the proposed construction site. Animal health experts warn that noise, light pollution, and other disturbances from the data center could disrupt the sensitive habitats of clouded leopards and other species, such as hyacinth macaws and okapis, another endangered forest-dwelling animal slated for a new exhibit.

Zoo President Rick Schwartz and Dr. Heather Schwartz, who oversees the zoo’s animal health, voiced alarm at the project’s proximity, emphasizing the lack of time to fully assess the impact on wildlife. They noted that the zoo had previously considered purchasing neighboring buildings—the ones now slated for demolition and redevelopment by DC BLOX—to expand conservation and educational efforts.

DC BLOX’s chief revenue officer, Chris Gatch, acknowledged that more community engagement could have occurred before filing the permit but defended the company’s plan, stating that they do not believe the data center would harm the zoo’s animals. He highlighted that the site is in an area designated for industrial use, and pointed out that Nashville’s growth necessitates accommodating new data center infrastructure. Gatch also dismissed comparisons to the previous smaller facility as inadequate to contextualize the scale of the new campus.

Despite reassurances, the debate reflects wider tensions in Nashville over rapid urban growth, environmental preservation, and infrastructure needs. Residents have voiced concerns about other potential impacts, including increased power consumption and environmental pollution. Opponents have filed challenges aimed at requiring the project to undergo further review amid a new Tennessee law that grants certain property rights upon permit application filing, rather than upon final approval.

With the clock ticking and a moratorium set to expire in November, community leaders and residents are mobilizing to influence how Nashville balances technological expansion with the protection of its cherished local institutions and wildlife.
