The city Department of City Planning has been studying 12 to 15 neighborhoods across the five boroughs that are "ripe for increased density," said Alicia Glen, New York City's deputy mayor for housing and economic development at a Crain's real estate conference on Tuesday. She also noted that she expects to see buildings to start stemming from the administration's rezonings by the end of 2015. Each neighborhood development will be extensively studied, and each will take four or five years to complete, according to Ms. Glen.
In terms of how much of the new developments will be required to be affordable under the city's new mandatory inclusive zoning plan, she predicted there would be no hard and fast rule.
"It's going to be neighborhood by neighborhood," Ms. Glen said. "There is no magic wand that we'll wave and everybody has to build 20% or 30% affordable housing."
She pointed to East New York and central Brooklyn as two areas that would likely be targeted for heightened development. In the case of Central Brooklyn the deputy mayor pointed out that it is significantly less dense today than it was for most of the 20th century, which means that it already has the transit capabilities and infrastructure in place to support increased numbers of residents. The administration's mandatory inclusionary zoning rules will also be driven by neighborhood needs, she said.
