Voters in the Milwaukee suburb of Port Washington have voted to limit the construction of future data centers, unless the community has a say. The measure was passed through a grassroots effort that required collecting signatures across the 12,000-person town. The vote was prompted by a controversial project in the area, the Vantage Data Centers Lighthouse Campus, a $15 billion computing hub for OpenAI and Oracle, which is part of a $500 billion Trump-backed initiative known as "Stargate". The ordinance will require approval from voters for tax breaks for development projects over $10 million. However, it will not halt construction of an AI data center project that began in December.
