Mayor Bill de Blasio last week unveiled a sweeping new plan to restructure the city's homeless shelter system and open 90 new shelters in the next five years. NY1's Courtney Gross takes a look at where those shelters could possibly go, locations that could become flashpoints for neighborhood pushback. 

Mayor Bill de Blasio says he wants to keep homeless people closer to the communities where they come from. 

"The people who will be served will be from your community. Every community will take care of their own. And we're going to match the number of folks in shelter to the capacity in the community," de Blasio said.

It's a critical piece of the mayor's new plan to open 90 new homeless shelters throughout the city. 

So NY1 examined data from last October, showing where the nearly 60,000 people in the shelter system had once called home, their last known address.

Each marker represents a community district. The darker the marker, the more people are coming from that area into the shelter system.

The highest number goes to Community Board 5 in Brooklyn covering East New York. More than 2,800 people had entered the system from there. 

Right now, there are not enough shelters in the district to house them all. 

Next comes Community Boards 4 and 5 in the Bronx, including West Concourse and Morris Heights. 

They are areas that are full of cluster-site shelters, which are landlord-operated and known for poor conditions. The city has promised to shut them down. 

That means all these areas could get some of the new shelters. 

Other communities with a number of shelters now could get even more, while neighborhoods with fewer people entering the system could get a lot less. 

Take Community Board 12 in the Bronx, the northern edge of the borough. 

"The idea that we are not adequately addressing the needs of this board is a little frightening," said George Torres, district manager of Bronx Community Board 12.

There were more than 1,900 people who came into the shelter system from here. But the area only has space for a little more than 1,000 individuals in shelters. 

"I don't want to pit one Bronx community versus another Bronx community. The concern in citing these facilities is, you have some district that are already overburdened. And I feel like Community Board 12 is one of those districts," Torres said.

We do not see this debate ending anytime soon as communties across the city continue to discuss what exactly it means to do their fair share.
