San Antonio ICE Detention Center: DOJ Talks on NEPA Pause

The San Antonio ICE detention center planned for a 640,000-square-foot East Side warehouse may be put on hold while the federal government studies its environmental effects, under a deal the city says it is negotiating with the Justice Department. City attorneys said Nov. 9 that DOJ contacted them after San Antonio sued DHS and ICE in October, and that the proposed agreement would pause both the lawsuit and the conversion work while reviews under the National Environmental Policy Act are carried out. Nothing has been signed, and no court filing on a deal has been reported.

ICE has the money and a target date but not the environmental paperwork. The 2025 reconciliation law set aside $45 billion for immigration detention, available through September 2029, according to Axios. ICE held 65,765 people in detention as of July 11, 2026, 70.6 percent of them with no criminal conviction, and Texas held more ICE detainees than any other state in fiscal 2026, 16,450 as of July 9, according to data compiled by TRAC at Syracuse University. The site at 542 Southeast Loop 410 is designed for up to 1,500 people, and KENS 5 reported ICE is targeting June 2027, so a review that runs well into next year would collide with that schedule.

What the city says, and what Washington has not said

The City Attorney’s Office said DOJ “reached out to begin discussions on the federal government’s plans to comply” with NEPA, that under the proposed agreement “work to convert the property into a detention facility would not proceed during that process,” and that “details are still under discussion,” News 4 San Antonio and the San Antonio Express-News reported. Mayor Gina Ortiz Jones said the agency “has said they will comply and do an environmental review,” according to the Express-News. DHS and ICE did not respond to requests for comment from the Express-News and KSAT, so the federal government has not described the terms itself.

“We’re still very much in the fight,” District 7 Councilwoman Marina Alderete Gavito told the Express-News, while District 2 Councilman Jalen McKee-Rodriguez told the paper a full environmental impact review could take up to a year. Councilmembers Marc Whyte and Misty Spears opposed the suit when it was filed, calling it the wrong fight, News 4 San Antonio reported.

Federal money is already sunk into the building. ICE bought it for $66.1 million earlier this year, KENS 5 reported, and awarded GardaWorld Federal Services a $17.3 million conversion contract in August that federal contract records show has grown to $61.8 million, according to KSAT. ICE, in a press release quoted by Fox San Antonio, projects 1,211 jobs and more than $26.6 million in tax revenue and says the site would undergo community impact studies.

Why a negotiated pause may suit both sides

NEPA is procedural. It requires an agency to study a major project first, through an environmental assessment and, if effects look significant, a longer impact statement, but it does not let a judge veto a detention center on policy grounds. For the city, a pause delivers most of what an injunction would, without the risk of losing in court. For the government, doing the study removes the suit’s strongest claim, that no review was done at all. Because the Supreme Court’s 2025 ruling in Seven County Infrastructure Coalition v. Eagle County requires wide deference to agencies on a review’s depth, a completed assessment is likely to be far harder to attack than a missing one.

The open question is which document DHS prepares. An environmental assessment that ends in a finding of no significant impact could take months and leave the city a narrow challenge. City Attorney Andy Segovia told Texas Public Radio when the city sued that he expects significant effects, which points toward the longer path, as covered when San Antonio filed its NEPA lawsuit.

San Antonio would join other conversions slowed by environmental law rather than immigration rulings. Federal officials agreed in May to delay a Roxbury, N.J., warehouse until an environmental assessment is done, New Jersey Monitor reported. See the frozen New Jersey detention center. In September, a federal judge halted construction of an ICE facility in Gilroy, Calif., in a suit by Santa Clara County and the state, after finding no proof of an environmental analysis, ABC7 reported. Site-level fights matter more to opponents because a new Congress has limited ways to claw back multiyear ICE funding, and the administration has vowed no slowdown in enforcement after the midterms.

What to watch

A joint motion to stay the case in federal court, which would make the pause formal and enforceable.
Whether DHS announces an environmental assessment or a full impact statement, and whether it opens a public comment period.
Whether work actually stops and ICE revises its 2027 target.
