Faced with mounting social needs and continuing fiscal constraints, more and more cities “mint” money through their zoning codes to finance a wide array of public amenities. Through the land use regulatory technique formally known as “incentive zoning,” cities grant private real estate developers the legal right to disregard zoning restrictions in return for their voluntary agreement to provide urban design features such as plazas, atriums, and parks, and social facilities and services such as affordable housing, day care centers, and job training.
