Data Centers

Data centers are specialized facilities that house the computing and networking systems needed to run applications and to store, process, and manage large amounts of data.

The demand to develop new data centers has been rapidly increasing amidst the Artificial Intelligence (AI) boom. As data centers become increasingly common nationwide and in the St. Louis region, concerns have arisen around their environmental, economic, and community impacts.

Large-scale data centers can require tremendous amounts of water and energy to sustain, straining local utilities and potentially impacting residents’ utility bills; create noise and heat pollution; and cause other nuisances that negatively affect surrounding neighborhoods.

Planning Commission considers Data Center zoning regulations

February 5, 2026 6:00 AM - March 12, 2026 5:00 AM

The City of St. Louis Planning & Urban Design Agency (PDA) published a detailed report and proposed framework for data center zoning regulations on February 5, 2026, as the City seeks to establish clear and thoughtful rules on where and under what conditions and requirements data centers could be allowed in the City of St. Louis.

The framework presented in the report remains a work in progress and will be refined through community feedback, stakeholder conversations and discussions with the Planning Commission and the Board of Aldermen. The recommendations will be presented at the next Planning Commission meeting on Wednesday, Feb. 11. Members of the public will be able to attend and comment at the public hearing held during the meeting.
