Avoidance of building in hazard zones: Prevention by designation of specific grassland or protection zones in development or zoning plans
Damage from pluvial floods can be reduced by taking pluvial floodwaters into consideration in development and zoning plans and by establishing free pathways for runoff. This can be done by building regulations, e.g. by designation of special grassland or protection zones in risk areas in the zoning plan. Such zones serve for retention and a controlled discharge of the water masses in case of heavy rain.
