Voters in Monterey Park, a city of about 60,000 near Los Angeles, approve what multiple outlets describe as the first U.S. citywide permanent ban on data centers enacted through a public vote. In a special election on June 2, residents backed Measure NDC by a wide margin, with early results reported around 86% in favor. The measure amends the city’s land use plan to prohibit data centers across the city in perpetuity.

Supporters, including the mayor and City Council, argue the ban is meant to protect air quality and drinking water and to prevent public-health impacts, as well as limit effects on local electricity and water rates. They also cite concerns that data centers are difficult to remove once allowed.

The decision follows months of opposition to a proposed large facility, described by sources as roughly 247,000 to 250,000 square feet, that had been planned by HMC StratCap. After residents organized and pushed officials to change course, the company reportedly backed away rather than pursue legal action.

Other jurisdictions have taken steps such as moratoriums, including in Maine and the Milwaukee suburb of Port Washington, but Monterey Park’s vote stands out as the first voter-enacted permanent prohibition.
