"New York City’s Department of Environmental Protection (DEP) recently funded three new urban agriculture projects: a rooftop garden at a settlement house, a vegetable garden near the Gowanus Canal and a commercial rooftop farm atop a Brooklyn Navy Yard building. These projects are part of an innovative green infrastructure program to turn impervious roofs, vacant lots and streets into spaces that soak up the rain and prevent water pollution."
