Dozens of Crown Heights residents showed up at a town hall meeting Thursday evening to oppose the opening of a new family shelter in their neighborhood, part of Mayor de Blasio’s plan to open 90 new shelters citywide.

This shelter is supposed to house 132 homeless families with children who are also from Crown Heights. But in this community district, which already has 15 shelters, Dion Ashman had a message for the Mayor: open a shelter in his own neighborhood.

“Let him know before he even touches Crown Heights again that he needs to put that shelter in Park Slope,” he said.

Ashman said he'd spent 53 years in the neighborhood and worked on improving it. Now, he’s devising a plan to protect Crown Heights from taking on even more shelters.

“We will be moving forward with a great deal of action,” he said.

He said that may include following in the footsteps of residents from a neighboring community district. They got a preliminary injunction against a shelter for senior men that was supposed to open last month.

Another resident who came to Thursday's town hall, Ann McKenna, said she’s opposed to the family shelter because she believes the homeless already have a negative impact on her neighborhood.

“They loiter in the subway. They loiter in the streets,” she said. “They beg people for money and follow people.”

The city said it plans to open the family shelter in Crown Heights in May, but reduce the overall number of shelters in the district to six by the end of June.
