Sandymount Flood Defences

A flood defence scheme for the promenade section, mainly remedial and strengthening works to the existing floodwall are being investigated. The provision of floodgates to pedestrian access points would be required. The assessment of different solutions for flood alleviation works between Sean Moore Park and the promenade have been considered. Environmental appropriate assessment studies are currently being progressed.

Chapelizod Works

The removal of fallen and overhanging trees was completed by the weir at Chapelizod. River debris and excess silt have been removed immediately downstream of this weir, and existing channels between the river islands have been restored.

Camac River

Following the flooding of 24th October 2011, emergency works were carried out to reinstate the collapsed floodwall at Lady’s Lane. The scheme involved the construction of 90m of new floodwalls and other ancillary works. The contract was substantially completed in August 2012. These works do not afford protection to the National standard of 1:100 year event for fluvial flooding but reinstate the level of protection that existing prior to October 2011. The Eastern Region Flood Risk Assessment and Management Study for both the Camac and Poddle rivers has been advanced, and it is anticipated that an overall cost beneficial scheme may arise from this study to give flood protection to areas of the Camac river that are prone to flooding.

Fitzwilliam Quay

This contract involved the reconstruction of a section of approximately 40m of quay wall the collapsed into the river at Fitzwilliam Quay. The contract involved the placement of king post piles, contiguous bored pile, ground anchors, reinforced concrete walls and ancillary works. The contract was completed in May 2012.
