Flood Hazard: Planning Approach To
Risk Mitigation

Abstract
Control of risks associated with floods in recent years has a central role in urban
planning scientific research. This is related to the increased incidence of these
phenomena whose the root cause was found in the greater frequency of extreme
rainfall events as a result of climate change. In Italy the phenomenon became
dramatic because of the numerous human casualties that occur each year.
Without prejudice to the need for interventions that effectively act on climate
change, there is a need to provide interventions to mitigate the consequences in
the short-term. The Department of Urban Planning at Naples University has
conducted a thorough research on the case, objectively verifying the impact that
human activity has on the dramatic consequences of rainfall events, also
highlighting the lack of efficiency of the traditional mitigation measures based
on the construction of huge detention basins dug in the ground. This is due to
three main reasons: such interventions require financial investments that local
communities often do not have; the creation of detention basins cause the
removal of large quantities of soil for agricultural use; the continuous increase in
impervious surfaces due to urbanization implies the need to cope with the masses
of water ever more impressive and therefore the dry ponds already created
quickly become insufficient. The research proposes some interventions and best
practices that, if adopted, can radically reduce the impact of extreme rainfall on
public safety, enabling an efficient participation of private capital in investments
through the use of leverage financial and fiscal incentives.
Keywords: flood risk mitigation, anthropogenic activity, impervious surfaces,
urbanization, slow-release tanks.
