Requirements and possibilities of best management practises for storm water run-off from the view of ecological townplanning

The character of urban water cycle does not comply with the principles of sustainability. The task of restructuring the urban water cycle is to create a system which is close to a natural. The approached method for this research was to develop and demonstrate a new comprehensive system in two cities of Germany (Dortmund and Zwickau). Standardized types of settlement structure were developed in order to obtain transferable results and to portray the total spectrum of urban planning situations.
