A day after Mayor Bill de Blasio unveiled a sweeping plan to fight homelessness, City Hall revealed the locations of four of 90 proposed new shelters. NY1's Courtney Gross filed the following report.

The city's homeless czar is hopeful about the mayor's new plan to open 90 homeless shelters in the next five years. 

"It's been a successful process that we have already opened one of the four, and we are at the beginning of the process with the other three,"

But NY1 has learned the exact locations of the first four shelters in that plan. And if those are any indication, City Hall is in for a big fight.

"I want to emphasize the fact this is not a NIMBY conversation. It's a fairness and equity conversation," said City Councilman Robert Cornegy of Brooklyn.

"I want to make sure this is an issue the entire city of New York is addressing together and not certain neighborhoods that are being singled out specifically," said City Councilman Laurie Cumbo of Brooklyn.

Local representatives do not seem happy. 

Take a shelter in Robert Cornegy's district. It's slated to be a shelter for about 100 single men age 50 or above. The shelter is two blocks away from the Brooklyn Children's Museum.

Cornegy says his district already has 15 shelters. 

"The residents in close proximity to that shelter are really upset. They believe it will have a negative impact on everything from their property values to their quality of life," he said.

There are two more slated for that area of Brooklyn.

About twelve blocks away, there will be a shelter for families with children.

Another shelter for women is slated for Prospect Heights.

Both of those are in Cumbo's disrict. 

"We just do not have enough information," Cumbo said. "We are demanding at this time that we have a thorough and comprehensive understanding so that we can talk with our community and find out how they are feeling about this."

City Hall has promised to engage the community more. In fact, the mayor has said community members should get 30 days' notice before the city opens a new shelter. 

But still, out of the first four, just one was immediately welcomed. A LGBT shelter opened in Ritchie Torres' district last week.

"Again, the need is real, and the mayor does have an obligation to site shelters and provide people with temporary housing," Torres said.
