St. Charles City Hall had a standing-room-only vibe Tuesday night as residents pressed the City Council to decide whether data centers should be banned inside city limits. Supporters of a ban warned that large, warehouse-style facilities could strain water supplies, drive up energy demand, generate constant noise and alter neighborhood character. Opponents countered that tighter regulations, not a blanket prohibition, would better protect the city's interests. After hours of public comment, councilmembers took no vote, leaving a final decision for May 19.
What the ordinance would change
City staff's draft zoning amendment would add a formal definition of "data center" to Chapter 400 of the city code and revise the current definition of "warehouse" so that data centers are no longer listed as permitted or conditional uses. Under the way the code is structured, that change would effectively keep data centers out of St. Charles. Staff says the rewrite follows a yearlong moratorium and a review of potential water, power and noise impacts; the draft and staff memo are posted in the Agenda Center at City of St. Charles.
Voices at City Hall
Dozens of residents took turns at the microphone, and the room was sharply divided between those calling for an outright ban and those urging caution. Supporters of the ordinance leaned heavily on water, energy and noise concerns, with Kara Elms of the City of St. Charles Clean Water Advocates among those pressing the council to move forward. Opponents argued that the city should continue to regulate new developments rather than prohibit them entirely, according to First Alert 4.
Part of a larger Missouri fight
St. Charles is hardly alone in wrestling with where massive computer facilities should go. The council first imposed a one-year moratorium in August 2025 after a proposed 440-acre project near Highway 370 drew hundreds of opponents, as reported by GovTech. Backlash over data centers has already had political consequences in nearby Festus, according to reporting from KCUR. Protesters have also rallied in Nodaway County against a proposed AI data center, local station KQ2 reported.
What to watch next
Councilmembers did not take action at Tuesday's meeting. The ordinance is scheduled for a final vote on May 19, city records show, and staff is expected to continue studying infrastructure impacts and collecting public comment before the council decides.

Why the fight matters locally
The zoning debate is tied to bigger questions about incentives and who pays for regional infrastructure. Statewide reporting has identified roughly $77 million in data center sales tax breaks that are helping fuel local skepticism. For background on those incentives and neighborhood pushback, see coverage of $77 million state data-center tax breaks.
