With just days left before the City Council takes a vote on Mayor de Blasio's plan to close Rikers Island, supporters of the proposal are turning up the pressure.

"Thursday, the City Council gonna vote,” said Reverend Al Sharpton at a Nation Action Network rally. “They should vote against the keeping of Rikers Island, they should close it. Call, email your councilman and let ‘em know you can play games all you want, but I am a voter and I'm telling you I want to see this plan."

Nearly three years after closing Rikers was first proposed by former City Council Speaker Melissa Mark-Viverito, the plan to shutter the notoriously violent jail is closer to becoming a reality.

Jonathan Lippman, former chief judge of the State of New York, helped author this report, which has served as a roadmap to close the facility and replace it with four smaller, borough-based jails.

“We've been working on this for two-and-a-half years and I think we are going to see a lot coming together in terms of the councilmen who are thinking about it, they're coming to final conclusions,” said Lippman. “The time is now, if we don't get this done now, it's going to be another 30 years that Rikers Island, that miserable, horrible place will continue to exist and we can’t allow that."

As the de Blasio administration and the City Council head into final negotiations, sources tell NY1 the administration is working to increase program funding and other services where the new jails would be located.

But some members of the Bronx and Queens delegations remain opposed to the plan.

"I think there is going to be a community reinvestment announcement that’s what we are really talking about,” said Stanley Richards, the executive vice president of the Fortune Society. “As we reduce the number of people who are going through the criminal justice system, there's going to be a significant reinvestment in those communities that's hardest hit. I know those 'no' votes are not going to vote 'no' against community reinvestment."

A vote on Mayor de Blasio's plan to close Rikers Island is scheduled for next week. Every jail facility on the island is expected to close by 2026.
