Flood Map for Planning – 3.3% AEP defended (present day)

The Flood Map for Planning includes several layers of information, which includes data created to support the use of Flood Zones in the planning process. This dataset shows the extent of land at risk of flooding to a defined annual exceedance probability (AEP) or chance of flooding each year.

This dataset represents the following scenario:

● Defended: 3.3% AEP (1 in 30) Rivers/Sea

Defended products take into account the presence of flood defences and assume that they operate in the way they were intended (or designed) to function. This does not include any asset failure (or removal) scenarios.

This dataset is designed to only give an indication of flood risk to an area of land and are not suitable for showing whether an individual property is at risk of flooding. This is because we cannot know all the details about each property.

Information on flood depth, speed or volume of flow is not included. Attribution statement: © Environment Agency copyright and/or database right 2025. All rights reserved.
