City Council Speaker Corey Johnson said New Yorkers are furious that Big Apple first lady Chirlane McCray’s $1 billion mental health plan ThriveNYC spends just a fraction of its behemoth, taxpayer-funded budget on the people who need the most help.

“You’ve seen anger from the public who see a huge amount of money associated with it and they still see a tremendous number of seriously mentally ill people living on the streets and on the subways and people are saying, ‘If you’re spending that amount of money on mental illness in New York City, why isn’t it going to those people,'” Johnson said Tuesday on Fox 5’s “Good Day New York.”

Johnson announced that the council redirected some ThriveNYC funds — to launch another McCray initiative, the $43 million New Family Home Visits program.

He praised that program as a “good thing” because it’s about postpartum care, but he stressed that more than 13% of ThriveNYC’s budget should go toward helping the seriously mentally ill.

“I think a majority of that money, not 13%, needs to go to people with serious mental illness,” Johnson said. 

“One of the big things in New York City that we’re seeing right now is there are not enough long-term care, psychiatric care beds so even if you get someone in the hospital, even if you get someone into treatment, there aren’t enough beds right now to keep them for a long period of time to get them stabilized,” he said.

Johnson said it’s unclear if ThriveNYC is effective because “they haven’t had metrics in place.”

But he is hopeful that its new director, former NYPD Deputy Commissioner Susan Herman, will improve the program.

“She’s a talented person. I think she’s trying to rationalize it and right-size it and bring in metrics and understand what agencies are doing what and to be really clear about how it’s working and how it’s not working,” Johnson said.
