It is important to emphasise that eliminating zoning will not address the problems of social segregation and segregated land use if conditional urban developments are not grounded in a city-wide vision for urban spatial development. The German zoning system provides a useful example of an approach that relies on zoning, and also allows for flexibility and a mix of uses throughout most of an urban area. As in single-use zoning, land-use zones are separated into categories, such as residential, commercial, industrial and mixed use. However, in each zone, other uses are also allowed either automatically or based on conditions (see Table 2.4).
