Dubuque County supervisors split on data center ordinance as residents voice concerns

Dubuque County supervisors are currently divided over the specifics of a new data center ordinance, despite a consensus that such regulations are necessary to safeguard local resources and residents. The county previously enacted a 12-month moratorium on data center development in May, and no formal applications have been submitted to date.

During a recent work session, Supervisor Ann McDonough questioned the necessity of data centers in the community, suggesting the ordinance could ultimately prohibit hyperscale facilities. This viewpoint clashes with Supervisor Wayne Kenniker, who advocates for a workable ordinance rather than an outright ban. Supervisor Harley Pothoff expressed concern that continued disagreement would hinder progress.

Residents, including commercial airline pilot Matt Moore, voiced strong opposition, citing worries about potential electromagnetic interference with the Dubuque Regional Airport and the University of Dubuque aviation program. Moore also expressed a desire to preserve the county's rural character, stating he prefers "farms, not server farms." Ron Breitbach, a member of the Dubuque County Zoning Commission, questioned the financial benefits data centers would bring to the county in terms of tax receipts.

The supervisors acknowledge the need to evaluate data center impacts on environmental preservation, water and utility infrastructure. The county plans to hold weekly work sessions and at least four public town hall meetings by October 1, 2026, aiming to release a draft ordinance within four months and a final version in about 10 months after further public input. The first information meeting is scheduled for June 23 at the Peosta Rec Center.
