Floodplain
A floodplain is land adjacent to a watercourse over which water flows or would flow in times of flood, if defences were not in place.
The flood zone area classification system devised by the Environment Agency refers to:
- Flood Zone 1: Land outside the floodplain. There is little or no risk of flooding in this zone.
- Flood Zone 2: The area of the floodplain where there is a low to medium flood risk.
- Flood Zone 3: The area of the floodplain where there is a high risk of flooding.
