Why It Matters
A push to disincorporate the Arizona city of Surprise has emerged as one of the most aggressive local responses yet to the Trump administration’s immigration detention expansion. If successful, the effort would strip the city council of its authority and hand governance to the Maricopa County Board of Supervisors — a drastic maneuver that activists say reflects their frustration with elected officials who have declined to formally oppose a federal detention facility planned in their backyard.
What Happened
Lobbyist and progressive advocate Jeremy Helfgot filed a disincorporation petition with the Maricopa County Board of Supervisors on Tuesday, timed to coincide with the Surprise City Council’s final meeting before its summer recess. The petition argues that because the council has refused to take a public stand against a planned immigration detention center, residents should have the option to transfer local governance to the county level.
The U.S. Department of Homeland Security purchased a 418,400-square-foot warehouse in Surprise in January and began plans to retrofit it into an immigration detention facility. The site sits roughly one mile from a public high school whose student body is more than 60 percent Hispanic. Initial plans called for housing up to 1,500 detainees, though that figure has since been reduced to 542. GardaWorld Federal was contracted as the private security provider for the project.
Mayor Kevin Sartor has consistently maintained that the city lacks legal authority to act against a federal installation. In March, Sartor and four other city officials met with DHS officials to request revenue reimbursement and a formal enforcement agreement — stopping well short of opposition. More than 1,000 residents packed a February council meeting to demonstrate against the facility, with little visible impact on the council’s posture.
“If the city’s elected and professional leadership cannot stand up, will not stand up, will not take a stand to even meet with their constituents to discuss critical issues of safety and security, then maybe this city doesn’t deserve to have its own independent control,” Helfgot said on June 16.
Resident Brittany Bishop framed the stakes in blunt terms, warning that allowing the facility to open would permanently define the city’s identity.
By the Numbers
173,000 — approximate population of Surprise, Arizona’s fastest-growing cities.
70,000 — signatures activists estimate are needed to meet the two-thirds voter threshold required by the petition.
6 months — the window organizers have to gather those signatures once the Maricopa County Board of Supervisors approves the petition language.
542 — current planned detainee capacity after a federal stop-work order was issued and subsequently rescinded, prompting a scale-back from the original 1,500.
3 of 6 — nonpartisan Surprise City Council seats up for election this year, giving opponents a potential electoral avenue alongside the disincorporation effort.
Zoom Out
The Surprise situation reflects a broader national pattern in which local governments find themselves caught between federal immigration enforcement priorities and vocal resident opposition. The Trump administration has also pursued policy changes that could affect the status of hundreds of thousands of DACA recipients, adding urgency to immigration-related activism at the state and municipal level.
Arizona Attorney General Kris Mayes filed a lawsuit against the Trump administration in April, arguing that federal law bars the warehouse conversion because of a hazardous chemical storage facility nearby. That litigation represents the most formal legal challenge to the project so far. The Arizona Legislature closed its 2026 session after an all-night push on several high-profile measures, leaving immigration-related local conflicts largely unaddressed by state lawmakers.
What’s Next
Before signature gathering can begin, the Maricopa County Board of Supervisors must review and approve the petition language. If that hurdle is cleared, activists will have six months to collect roughly 70,000 valid voter signatures — a significant organizational undertaking in a city of 173,000. Three council seats are also on the ballot this year, offering a parallel path for opponents of the detention facility to reshape local leadership through conventional elections. Attorney General Mayes’s lawsuit remains pending, and its outcome could affect whether the warehouse conversion proceeds regardless of the disincorporation effort’s fate.
