Florida taxpayers could be on the hook for the $218 million cost of converting a training airport in the Everglades into an immigration detention center that may soon be empty of detainees.

ORLANDO, Fla. (AP) — Florida taxpayers could be on the hook for $218 million the state spent to convert a remote training airport in the Everglades into an immigration detention center dubbed “ Alligator Alcatraz.”

The center may soon be completely empty as a judge upheld her decision late Wednesday ordering operations to wind down indefinitely.

Shutting down the facility for the time being would cost the state $15 million to $20 million immediately, and it would cost another $15 million to $20 million to reinstall structures if Florida is allowed to reopen it, according to court filings by the state.

The Florida Division of Emergency Management will lose most of the value of the $218 million it has invested in making the little-used airport suitable for a detention center, a state official said in court papers.

Built in just a few days, the facility consists of chain-link cages surrounding large white tents filled with rows of bunk beds. As of late July, state officials had already signed more than $245 million in contracts for building and operating the facility, which officially opened July 1.

President Donald Trump toured the facility last month and suggested it could be a model for future lockups nationwide as his administration races to expand the infrastructure needed to increase deportations.

The center has been plagued by reports of unsanitary conditions and detainees being cut off from the legal system.
