Manhattan has become the third borough to reject citywide zoning proposals that are key to Mayor de Blasio's ambitious affordable housing plan. As NY1's Michael Scotto reports, it's likely the plans will be overhauled before the City Council votes on them.

Mayor Bill de Blasio is running into major opposition as he tries to push forward his plan to build or preserve 200,000 units of low- and middle-income housing.

On Monday, the Manhattan Borough Board — made up of the borough president, community board chairpersons and city councilmembers — approved resolutions rejecting two key zoning proposals unless they are revised, the third borough to do so.

"This proposal is way too broad and way too unified," said Community Board 4 Chairwoman Christine Berthet.

"We all want affordable housing," said Manhattan Borough President Gale Brewer. "We know how to get there. And I think that's what the Administration needs to look at."

The mayor's proposals would require affordable housing units in all new apartment buildings in newly rezoned neighborhoods and allow, in some cases, developers to build taller.

But, some Manhattan leaders worry the affordability requirements wouldn't be strong enough and that taller buildings would hurt the character of neighborhoods and accelerate gentrification.

"We want the hills and the valleys, we want sunlight, obviously we welcome any new development but it should be development that takes into account the community that is there," said Community Board 12 Chairman George Fernandez.

Mayor de Blasio brushed off the votes, which are only advisory.

"It's a whole new approach and of course there will be doubting Thomases at first," the mayor said. "But over time I think we'll show people over time that it works."

The proposals are expected to be tweaked before the City Council votes on them next year. That vote by council members is the one that really counts. 

The head of the council committee responsible for zoning laws acknowledged the zoning proposals would have had more community support if they had more neighborhood-specific details.

"It would have been easier but it wouldn't be that pragmatic because realistically speaking, in order to build more affordable housing in the city of New York you have to look at the entire city of New York," said Councilman David Greenfield.

But as the Mayor is learning, it's often difficult to get the entire city on board with one plan.
