They’ll get out of shelters on their own.

That’s the shocking explanation Big Apple officials gave to City Council members Thursday on why they’re kicking single adult migrants out of city-run shelters after 60 days to make room for families.

“We have to make decisions every day that are impossible choices, ones that we don’t want to make,” said Zach Iscol, commissioner of the city’s Emergency Management Department.

So far, the city has issued approximately 1,500 eviction notices, with the clock starting on July 24, to migrants at emergency shelters run by its Health and Hospitals. If they can’t find alternative housing, they’re allowed to reapply.

“We should not underestimate the abilities, the resourcefulness, the agency of the people in our care,” Iscol said. “And a lot of them, I think, given 60 days, will find another place. They will be able to get out on their own feet.”

But Iscol warned the new revolving door for the shelter system could be quickly overwhelmed if the flow of migrants from the southern border does not slow down.

More than 103,000 people — roughly half of the migrants — are either living in city-run or city-funded shelters or other emergency facilities set up to provide shelter.

Desperate for space, officials are set to open tent cities in the parking lot of the sprawling Creedmore psychiatric facility in Queens and on soccer fields on Randall’s Island, said Ted Long, a top official at the city’s public hospital system, which will oversee the sites.

Progressives and homeless activists have slammed the administration for pursuing the policy amid the Big Apple’s larger housing crisis.

“The administration has not provided any further concrete plan for housing people who reached the 60-day limit,” said Public Advocate Jumaane Williams.

“Migrants are sleeping on sidewalks and parks and the bridges and highways.”

More than 54,800 asylum seekers are currently staying at one of Gotham’s 188 emergency shelter sites set up to cater to the migrant influx.
