Undoubtedly, stormwater management has to consider several objectives derived from overall environmental concepts. For a translation of these objectives into practical measures, concrete target values are necessary. Objectives and target values are needed for flood protection, water quality and the water balance. On the other hand, a large variety of different measures is available. These measures have different effects on different objectives and depend on many influential factors. The main future task for the engineer will be to find the "best" measure regarding the local conditions and the objectives. To provide assistance for this task, a catalogue with information about different measures is presented. The measures are compared regarding the water balance, the behaviour for typical design storms, the potentials for removing pollutants and the costs. With this catalogue a preselection of measures, for example for a master plan, is possible.
