Figure 3.18: Proactive and reactive policy

The advantage of proactive policy in flood risk areas is that the blocking of the roads will be
reduced to an absolute minimum. The roads can be opened for traffic directly after a flood. So
nuisance to the population and industry will be reduced to a minimum. Another benefit is that
the costs for the maintenance in a proactive policy are in general lower, that the maintenance
costs in a reactive policy. Access to the site is easier and the surroundings are not destroyed.
The cleaning of an affected area may also be a time consuming and an expensive activity.

In spite of the advantages the benefits depend on the specific case and location. The results of
a proactive policy will be compared with a reactive policy in chapter 4.
