Locations at significant risk (Greater Belfast Sub Plan)

Belfast is in a basin between two sets of hills. Many watercourses flow from these hills through small catchments either into the Lagan in the centre of Belfast or directly into Belfast Lough. Within the developed area of the city of Belfast, many of these watercourses are culverted.  As a result, there are many screens, grills and culverts that can cause localised flooding problems.

The main Rivers contributing to the flood risk are the Lagan, Blackstaff, Farset, Connswater, Knock and Loop. While there is little tidal flood history, there is potential for significant tidal flooding in the centre of Belfast as indicated on the publically available Strategic Flood Map.

Using information from the preliminary flood risk assessment (Word 60kb), we are currently in the process of determining areas at significant flood risk. When this is completed, we will post information in this section on the locations identified as being at significant flood risk within the Greater Belfast sub plan.
