Check your flood risk on a map (Flood Risk Assessment Wales Map)

Check if you're at risk

The Flood Risk Assessment Wales map shows your risk of flooding from:

• rivers
• the sea
• surface water and small watercourses
• reservoirs

The map also provides additional information about your area, such as:

• the location of flood defences
• the areas benefitting from flood defences
• shoreline management plans

This map has no official status for planning purposes. We advise you to use the information contained within the Flood Map for Planning / Development Advice Map for development planning matters. Together, these two maps form the Wales Flood Map. 

You can also see all the areas we cover for free flood warnings and alerts.
