Voters in Port Washington, Wisconsin approved a referendum that restricts data centers in their jurisdiction, reports Torrie Herrington for NOTUS.

According to Herrington, "While the Port Washington referendum requires city leaders to get voter approval before awarding tax incentives to data center developers, it does not stop the $15 billion Vantage Data Centers project already under construction."

While Port Washington is not the first city to advance or pass legislation regulating data centers, it is the first to pass a voter-approved referendum. A proposed moratorium on new data centers is making its way through the U.S. Congress.
