flood zones
Water risk regions
Flood zones are geographic areas classified by their risk of flooding, typically mapped by government agencies for insurance and construction purposes.
Properties in high-risk flood zones often require special insurance and face building restrictions.
The house was in a flood zone, so the mortgage required flood insurance.
The designation affects property values and development decisions.
