The city of New Rochelle, about 40 minutes from New York City by train, is a model for overcoming the NIMBYs that have halted development elsewhere. The suburb added 2,500 new apartments over the past eight years and has a total of 6,300 in the pipeline. One in five will be market rate, with artists getting first preference. How did they do it? Mainly by seeking extensive community input and expediting the zoning and environmental review process. Though it’s often tough to rally local political support for development, it’s integral to get buy-in from area residents and show them — using virtual reality goggles, for one — how areas can be revitalized.
