A polycentric region with several green corridors.
Greenway corridors can be laid out, at least partially, along existing stream corridors to take advantage of natural vegetation and ecology, but taking care to protect sensitive features – for example, placing the more disruptive pathways along the banks above stream corridors.
They can also be developed out of previous corridors, such as the Ringstrasse in Vienna redeveloped from the corridor formed by the old city wall.
