Hoover's Legacy: Bad Zoning Codes
"Under zoning, new neighborhoods were segregated by income, and commerce was torn asunder from both customers and workers. Timeless ways of creating great places were ruthlessly outlawed. The sprawl spawned by zoning spread from sea to shining sea.
Almost everyone admits the environmental and social devastation caused by sprawl. Yet it remains the law. What's been lacking is the tool for producing great places instead of bleak, auto-dependent landscapes. If "zoning" is the DNA of sprawl the coding that endlessly replicates the bleak landscape of autotopia, then what is the DNA of livable communities?
It is found in timeless ways of building, updated for the 21st Century, including the need to accommodate cars. It regulates incompatible uses without the absurdities of conventional zoning. It is calibrated for new buildings to contribute to their context and to the larger goal of making a great place. It does so primarily by regulating the form of buildings, since that is what determines the long-neglected public realm of streets and sidewalks."
