flood zone

Water risk territory

A flood zone is an area officially designated as being at risk of flooding, typically mapped by government agencies for insurance and building purposes.

Properties in a flood zone often require special insurance and face construction restrictions.

The term also applies more loosely to any low-lying area prone to flooding: We bought the house knowing it was in a flood zone.
