Madison considers where data centers could be built
Madison is developing a zoning framework that would permit smaller data centers in designated areas while limiting large facilities to industrial zones. The proposed rules would include noise mitigation and separation requirements, with public feedback through October and a formal council vote expected in January.
Madison officials are considering a data center zoning framework that would divide facilities into small, medium and large categories. The proposal would cap buildings at 100,000 square feet, restrict large facilities to industrial areas, require noise mitigation and impose at least 1,000 feet of separation between medium and large data centers. It would exclude hyperscale facilities and multibuilding campuses.
The city’s Department of Planning and Economic Development developed the preliminary framework after months of research. Dominic Parker, a professor of applied economics, said smaller facilities could reduce potential economic benefits such as jobs, property tax revenue and land sales, but might also limit noise and quality-of-life impacts. Madison plans to collect feedback from residents and business committees before introducing the ordinance to the Common Council in November, with a final vote anticipated in January.
