Dubuque County, Cascade, Iowa, enact data center moratoriums amid project proposals
Several jurisdictions in the tri-state area, including southeast Dubuque County and Cascade, Iowa, have recently enacted data center moratoriums. This action follows proposals for new data center projects in the region since December. The ongoing situation impacts the future of a planned data center in Cascade, which remains in the hands of private entities.
Local government bodies across the tri-state region, including areas within Dubuque County and the city of Cascade, Iowa, have implemented moratoriums on data center development. These pauses on construction and permitting come in response to a surge of proposed data center projects since December, including sites near Cassville, Wisconsin, and within southeast Dubuque County.
The Dubuque County Courthouse was reportedly filled to capacity during a county supervisors meeting on May 26, 2026, indicating significant public interest in these developments. The decision on a specific data center project planned for Cascade, Iowa, is now dependent on two unnamed private entities, following the imposition of these development freezes.
