On Thursday, the Department of City Planning (DCP) began the approval process for the plan, which looks to rezone about 300 blocks in the neighborhood to allow for thousands of new homes, including 4,000 units that would be income-restricted. The Downtown Core, running along Jamaica Avenue and Archer Avenue, would be rezoned to allow for buildings as tall as 18 stories and encourage high-density mixed-use developments with permanently affordable housing, active ground floor retail, and community services.
