We just got a huge win for one of the most important conservation areas in the South – the rural ACE Basin.
On behalf of local residents, SELC sued and just reached a settlement that prohibits data centers across a majority of the ACE Basin in Colleton County, South Carolina, including a massive 850-acre, $6 billion data center proposal.
This newly protected area is home to some of the most ecologically sensitive areas along the three major rivers that form the basin: the Ashepoo, the Combahee, and the Edisto.
This 1.6-million-acre watershed is steeped in rich history and diverse Lowcountry culture that also serves as prime habitat for waterfowl, migratory birds, and endangered species.
The agreement establishes a “Data Center Exclusion Area” covering a majority of the ACE Basin in Colleton County. Most significantly, it includes the 850-acre parcel on the headwaters of the Ashepoo River where the original Eagle Rock data center complex was proposed in December 2025.
Since the proposal was announced, Colleton County residents, environmental groups, and people from across South Carolina have made one thing clear: this is the wrong place for a data center.
We’re thrilled that this area will be protected from data center development but remain committed to continuing to work with county leaders, residents, and stakeholders to help ensure that any data center projects in Colleton County and beyond are developed responsibly and with the transparency and accountability communities deserve.
This victory shows us what we can accomplish when we work together with communities across the South.
Data centers are rapidly expanding across our region, and SELC is working alongside communities to ensure this growth doesn’t come at the expense of clean air, clean water, wildlife, and the people who call the South home.
Getting It Right: Local Approaches to Data Center Development
A new resource from the Southern Environmental Law Center demystifies one of the best—and sometimes only—tools to ensure responsible data center development: local zoning authority.
Data centers are an increasingly prominent part of our modern society and can power valuable services. But they are also extremely resource-intensive and can consume vast amounts of energy, water, and land. Their explosive growth in the Southeast and elsewhere is putting tremendous pressure on energy systems, electricity rates, water supplies, and natural and historic resources, while often generating significant air and noise pollution.
Local zoning authority often provides communities with their best opportunity to exert any meaningful influence over data center development. This report offers various considerations for using zoning ordinances and local advocacy to address the unique challenges data centers present and to promote transparent and accountable decision-making about these facilities.
Section One explores some of the community and environmental impacts that data centers can cause. Section Two discusses various options for how local zoning ordinances can effectively empower local governing bodies to address data center development in an informed, responsible, and transparent way. Section Three discusses real-world examples of data center-specific development requirements that could be included in zoning ordinances. Finally, Section Four offers suggestions on how communities can engage most effectively on individual data center proposals.
Combining thoughtful zoning ordinances with smart public involvement is one of the best strategies currently available for shaping responsible data center development, and it is one that all localities confronting this growing challenge should be pursuing.
