Summary:

Zoning and land development limitation is a management based adaptation approach that aims to minimize flood impacts on people and infrastructure. This approach divides urban areas into zones with varying degrees of development restrictions depending on flood-risk level. Construction or reconstruction is often prohibited in high-risk areas, for example floodplains, while in other areas restricted development is permitted, given certain building regulations are followed. These regulations address flooding impacts and resilience, thus ensuring buildings are constructed to withstand or adapt to flood events. Examples include requiring flexible buildings and infrastructure and setting minimum floor heights. Apart from reducing the risks and impacts of floods, zoning has a number of environmental benefits that can improve freshwater ecosystem resilience, which in turn makes it less likely to flood in the future.
