What’s this about?
The Built Environment & Health (BEH) project is an interdisciplinary program of research at Columbia University. Led by epidemiologist Andrew Rundle, BEH uses spatial data to examine the implications of the built environment, including land use, public transit, and housing, for physical activity, diet, obesity, and other aspects of health. With a focus on New York City, BEH research will inform public policy to promote health in the city and metropolitan area. BEH is affiliated with the Robert Wood Johnson Foundation Health & Society Scholars program at Columbia.
Zoning Change in New York City
Advocates for New Urbanism or “active living” often identify zoning as a policy strategy to make cities more walkable. Because zoning regulates both building size and land use, changes in zoning can affect both population density and the availability of shops and restaurants within a walkable distance. New York City Mayor Michael Bloomberg’s sustainability plan, PlaNYC, advocates rezoning city neighborhoods to allow higher-density development near subway stops, allowing more New Yorkers to use public transit instead of private automobiles.
However, zoning change can be a politically complicated process. Some communities resist “upzoning” because of concern about gentrification and displacement of low-income families, or about the loss of a distinctive neighborhood character. In fact, population growth in New York City has been accompanied by a wave of “downzoning,” in which neighborhoods seek to limit new, higher-density development.
With summer high school interns Alexa Nichols and Carolyn Ruvkun, BEH is studying zoning change in New York City between 2003 and 2007, with a focus on the more extensive rezonings required to go through the Uniform Land Use Review Procedure (ULURP) application process. Using ULURP applications as well as parcel-level data on zoning characteristics, this project will show whether recent zoning change has made the city more or less walkable.
