Avoidance of building in hazard zones: Appropriate location of houses on properties
Exclude new developments that would increase the damage by shifting the location of the planned building outside the hazard area of the property.

All pluvial flood events with damages should be documented and analysed regarding causes and impacts. The measure includes the assessment of buildings and infrastructure concerning their usability (e.g. transport routes, water supply, waste water disposal). Collected data are the basis for compensation requests to insurance or public disaster funds (if available). Moreover, lessons learnt can…
Potentially affected persons – esp. property owners – have to take personal provisions. However, establishment and maintenance of private protection structures is challenging and often not done on a regular basis. Authorities should promote and stipulate appropriate property protection measures at least by provision of information on web sites and written material.
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…
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…
Organisational precautions as well as emergency measures are taken immediately after an event in order to guarantee the functionality of structures that aim at the protection against pluvial flooding (e.g. removal of debris and mud).
