100 RISK REDUCTION MEASURES
Walls and dams for the protection of areas at high risk
By diverting the water away, adverse consequences in areas at risk are prevented in the event of floods up to design event levels. E.g. the property or parts of the property can be protected by a wall that surrounds the building and keeps running surface water away from it. However, before constructing a wall, investigations have to be carried out to determine whether the diversion of pluvial flood water does not infringe on the rights of third parties and if capacities for retention of water falling directly on the property are big enough. If necessary, additionally water retention measures have to be taken into consideration.
