National Flood Risk Maps

Flood risk maps provide an indication of flood risk from rivers, the sea and surface water.  

The Department of Infrastructure has developed island-wide indicative flood maps for river, tidal and surface water flooding.  Whilst these maps provide a good indication of the areas of land at risk of flooding, they do not contain sufficient information to be used to determine flood risk to individual properties. 

The interactive map allows you to view the flood risk types individually by turning on and off each layer.  Addresses can be located by entering a house name, road or postcode into the search bar at the top of the page.
