Angry constituents — including an activist who challenged Mayor Bill de Blasio at the Park Slope YMCA last year — demanded local action from the term-limited pol during a 2020 presidential forum Tuesday.

“I am the 72-year-old homeless woman who confronted you at your gym last October,” Nathylin Flowers Adesegun told the mayor during a Working Families Party 2020 Live Online Q&A in Manhattan Tuesday night.

“I asked you that you set aside more housing from your affordable housing plan for more homeless New Yorkers and you refused,” she scolded the mayor through a video feed.

“Your homeless plan will create twice as many units of housing for people who will pay over 2,500 per month in rent than it will for those who are homeless. Why should Americans trust someone who justifies spending public resources to build housing for people who make six figures while there’s record homeless and suffering in the city?” Adesegun asked.

However, figures from the Department of Housing Preservation and Development show that 11,553 new apartments for the homeless have been built, compared to 12,434 middle units for middle class families she was likely referencing — leaving a much smaller gap than her question suggested.

De Blasio responded to the activist who spoke up about 10 minutes into the hour-long forum.

“I respect all activists and I respect people who have a strong view, but there’s facts that need to be added to this equation,” he said.

He defended his affordable housing program, saying that 700,000 people will benefit from the plan.

De Blasio also said the program includes housing for the working and middle class because, “We want an economically diverse city and because people of all those income levels are struggling to live here.”

Another activist, Giancarlo Alicea Fernandez with the civic group Community Voices Heard, hammered de Blasio about conditions in the city’s beleaguered public housing authority.

“Mr. Mayor you have lifted up all that you have done for affordable and public housing in New York City, but as a resident of public housing in New York City I can tell you that the conditions in our homes are still undignified and dangerous,” Fernandez fumed.

“Toxic mold in my home has repeatedly sent my mother to the emergency rooms with migraine headaches,” he said.

Fernandez asked the mayor to commit $1 billion in city spending a year to repair NYCHA properties.

“So far in my administration we’ve committed $6 billion to fix public housing,” de Blasio claimed.

Actually the mayor has only promised or provided $4.4 billion, according to a press release his administration put out in March. Half the funds are legally required under a settlement with the federal government.

City Hall attributed much of the $1.6 billion gap to a de Blasio administration decision to end NYCHA’s payments to NYPD for police services and to the city budget in lieu of paying property taxes — worth more than $1 billion over 10 years.
