MEETING OF LUCAN / PALMERSTOWN / NORTH CLONDALKIN AREA COMMITTEE

Tuesday, September 23, 2025

MOTION NO.4

MOTION: Councillor C. Brady

This committee calls on the Chief Executive to report on recurring and severe flooding incidents in Lucan, including at Lucan Village, Hillcrest, and Finnstown. The report should include a full investigation into the causes of flooding at each location, identify which agency is responsible for providing a solution — whether South Dublin County Council or Uisce Éireann — and, where SDCC is the responsible body, provide a detailed engineering report outlining the underlying problems and setting out a long-term solution to mitigate future flooding.

REPORT:

SDCC responded to flooding events at 3 locations in Lucan following an Orange Rainfall event on 21st July 2025.  This orange rainfall event resulted in up to 50mm of rainfall in the Dublin area. These flooding events are surface water related and are the responsibility of SDCC.

South Side of Lucan Bridge - SDCC responded and found the gullies were blocked and were restricting the water flow.  The gullies were cleaned and the pipeline was jetted.     

Hillcrest - the gullies and pipeline were clear at time of inspection by SDCC.  This event has been recorded and will require further investigation if flooding reoccurs.

Finnstown - the flooding had gone at the time of inspection by SDCC.  The gullies and pipeline were jetted as a precaution.  This event has been recorded and will require further investigation if flooding reoccurs.

The Natural Water Section has noted these 3 flooding sites in Lucan and should these areas flood again, further investigation will be taken.
