At least 75 migrants will temporarily stay inside the gym at PS 188 in Coney Island, two NYC councilmen confirmed — with one of the pols calling the temporary site a “puzzling” move by City Hall.  

Dozens of migrants will be housed at the gym outside the Brooklyn elementary school with no timetable on how long the building will be used as an emergency site for migrants, City Council members Justin Brannan and Ari Kagan said Sunday evening.

“Unclear how long they will need to stay. This location remains puzzling to me,” Brannan tweeted.

Kagan, a Republican, also said in a tweet there was no “timeframe when this gym would be returned to the Coney Island community.”

The school is currently in Kagan’s district, but following the redistricting of council seats, both pols are fighting for the seat that would cover PS 188.

The migrants’ arrival comes just two days after the principal at PS 188 warned the city to choose the school facility as an emergency, temporary site for migrants.

Several migrant families were supposed to be sent to the stand-alone gym adjacent to the rest of the school building late last week, but the plan was put on hold amid community outrage.

The Big Apple continues to struggle mightily to house and care for the flood of migrants arriving from across the southern border – with many of them bused from border states like Texas. Over the last year, tens of thousands of migrants have reached the city.

Migrants could be seen milling around the Sandra Feldman Gymnasium Sunday night.

Antuan, a 21-year-old migrant from Venezuela, told The Post that officials informed him and others they were only staying at the building until Monday.

“They put us here because they don’t want us out on the streets,” he explained. “They’re processing us, giving us our paperwork and then we leave.”

Antuan, who reached New York on Sunday after eight months in Texas, said all the migrants were given a psychological assessment to determine whether they were dangerous before being sent to the Brooklyn neighborhood.

Brannan said in an interview Sunday that City Hall informed him the migrants began arriving at the school gym Sunday evening.

He questioned why city officials chose the Coney Island neighborhood for a migrant site because the area lacks services for them and public transportation is poor.

“And I think overall just housing folks in a public school setting, a public school gym, is just concerning and I think the location is just puzzling,” Brannan said.

The Democratic lawmaker also criticized how City Hall has communicated to the community about the site.

“I think people in the community are obviously compassionate and understanding but the way you find out about something, that colors everything,” Brannan said.

One neighbor asked why the school was the best place to house migrants.

“Why a school? That’s the part I don’t get. There’s always other options. A lot of the buildings around here, they have fallout shelters that are spacious, and used for emergencies,” a woman on the block told The Post.

School safety agents who work at PS 188 were also concerned about what their role would be with migrants there.

“School Safety Agents are trained to protect children, not migrants. National Guard and federal assistance are needed. We protect City school children. That’s our responsibility. Not migrants,” said Local 237 Teamsters spokesman Hank Sheinkopf in a statement to The Post Sunday.  

City Hall press secretary Fabien Levy said the city is opening emergency shelters and respite centers daily, “but we are out of space” in a statement Sunday night. More than 4,200 migrants arrived in the last week with the city receiving hundreds of asylum seekers daily, he added.

NYC Mayor Eric Adams has said repeatedly the city is running out of options with even more migrants expected thanks to the end of Title 42, a Trump-era policy that allowed for the quick expulsion of some border-crossers over COVID-19 concerns.

The policy ended last week.

City Hall has also faced uproar over its plan to bus migrants staying in city shelters to hotels in upstate Rockland and Orange counties. More than 80 migrants – all single men — were shipped to Newburgh hotels in Orange County, last week.

Orange County Executive Steven Neuhaus filed lawsuits Friday to stop the hotels from housing migrants. 

Rockland County also took legal to thwart the city’s plan.

More than 140 sites and eight mega-shelters have been opened in the city.
