QUESTION NO.13

QUESTION: Councillor N. Fennell

Recent heavy rainfall (weekend 14th/15th) saw water levels rise significantly at both the Liffey and Griffeen Rivers in Lucan, and above some of the new infrastructure, submerging the entire Weir Promenade and some building materials here and at the Village Green - To now ask the manager to detail any impacts that this might have on project completion works and timeline and if a statement can be made on the matter.

REPLY:

The Lucan Village Green and the Promenade at the Liffey Weir are situated in next to the Griffeen and Liffey Rivers, both of which are subject to periodic fluctuations in water levels. The design of the works have incorporated provisions to accommodate occasional flooding events.

During a recent heavy rain, the Griffeen River experienced a short-duration flood at the Village Green Amphitheatre. This event did not adversely affect the ongoing works. The release of water from the Leixlip Dam resulted in inundation of the Promenade area. To safeguard the works from unintended pedestrian access, temporary fencing had been installed. A section of this fencing was displaced by floodwaters and subsequently reinstated. In addition, all machinery was relocated away from the water to prevent potential damage.
