Zoning is way to control activities, which is important for a city. But as we all know cities are dynamic, some people even suggest that the city is a living organisim. froming this point of view, “zoing” should work in different ways comparing with exisiting and conventional “zoning” practices.
I think “zoning” is also a tool for the authority to managing the city. It is economic, social, and political matter—difficult to do much helping a better result as a powerless urban designer.
