MEETING OF LUCAN / PALMERSTOWN / NORTH CLONDALKIN AREA COMMITTEE

Tuesday, September 23, 2025

QUESTION NO. 1

QUESTION: Councillor C. Brady

To ask the Chief Executive for an update on noise monitoring in the Lucan-Palmerstown North-Clondalkin area, including progress on the implementation of the Noise Action Plan 2024-2028 including given the consistently high noise levels recorded by the Lucan monitor, what actions are planned to address this issue, and what is the expected timeline for implementation?

REPLY:

South Dublin County council have completed a pilot acoustic project in the Lucan area that had been identified as a High Priority Action Area in relation to environmental noise.  The aim of the project was to verify the representativeness of the strategic noise mapping results and to establish the effectiveness of sound mitigation measures on the N4 within South Dublin County Council.

Noise levels were calculated for two noise mitigation scenarios: the resurfacing of sections of the N4 with a lower noise road surface, and the implementation of a 50km/h speed reduction zone, assuming a constant population, in accordance with EPA guidance. Noise models for 2024 and 2039 were compared to assess the number of people exposed to noise and the associated health impacts.

While the project determined both mitigation measures to have a benefit, any noise mitigation measures carried out would have to be done in conjunction with Transport Infrastructure Ireland (TII) as the TII are responsible for the maintenance and upgrade of all major roads in Ireland one of which is the N4. Noise mitigation measures can however have impacts on other areas such as surface durability and traffic flows etc. 

Members of the Environmental Health team will participate in the Dublin Agglomeration Noise Working Group which incorporates members from the TII. We will continue to liaise with them in relation to environmental noise in Lucan.
