After a flood event the recovery phase starts. Initially, all the water needs to be removed, either by flowing away naturally or through pumping out of the area. The area then requires to be cleaned, with any damaged buildings and infrastructure restored. This process should be carefully planned, and be based primarily on the damage done by the storm event. Some basic infrastructure like roads, electricity supply, water supply and sewerage should be restored before individual properties can be restored and normal living and working functions can start again (see §7.3).
A common challenge is to make sure that there is sufficient money for recovery, either by private insurance, public compensation or a mix of both (see §7.2). If such instruments are not in place, there is a risk that restoration of certain areas will take a significant time or will not be possible at all. An example of such a problematic situation is the recovery in New Orleans after hurricane Katrina which took up to four years to recover the principal areas, but with individual residences requiring up to double that time.
A final challenge is how to use the experiences and lessons from past flood events to improve future flood risk management (see §7.4).
Common challenges and related good practices can be found in Chapter 4 on integrated planning, collaboration and coordination, Chapter 6 (During a flood) and in this Chapter 7 (After a flood).
