Flood Map for Planning – Present day extents (defended and undefended)

Alternative title(s)

Abstract

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. They show the extent of land at risk of flooding to a defined annual exceedance probability (AEP) or chance of flooding each year. These scenarios show a present day risk; climate change scenarios are available separately. These datasets include the following scenarios: ● Undefended: 0.1% AEP (1 in 1000) Rivers/Sea ● Undefended: 1% AEP (1 in 100) Rivers/ 0.5% AEP (1 in 200) Sea ● Defended: 0.1% AEP (1 in 1000) Rivers/Sea ● Defended: 1% AEP (1 in 100) Rivers/ 0.5% AEP (1 in 200) Sea The undefended products show flood extents that ignore the presence and condition of flood defences. The 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. These datasets are 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.

Quality and validity

Lineage

These flood outlines are created using local flood model outputs and national flood model information. These are combined by our new National Flood Risk Assessment (NaFRA2) system to generate extents of land at flood risk, with the aim of using the best available flood risk information in any one location.
