Lower Dodder Flood Alleviation Works
Ringsend Bridge to New Bridge
All flood alleviation works are complete downstream of New Bridge. This work has entailed the placement of 665m of sheetpiles, the building of 1130m of reinforced concrete floodwalls and the construction of 130m of flood retaining earth embankment. The sheetpiles have mainly been placed to prevent a flow path for flood waters under the flood retaining structures to low lying estates such as Derrynane Gardens and O’Connell Gardens. Works at the Aviva Stadium were carried out in conjunction with the Lansdowne Stadium Development Company. These works now afford protection to the National Standard of a combined 1:200 year coastal and fluvial event for inter-tidal areas, and makes allowance for global warming to the year 2100.
Utility services, such as the 500mm County Sewer main have been re-laid to facilitate this work. This scheme also facilitated the upgrading of the footpaths along the banks of the river and the associated public lighting. Viewing platforms and benches have been placed by Lansdowne Lawn Tennis Club to enhance the river way for residents. Environmental mitigation measures such as the provision of fish holes in the river bed (on consultation with Inland Fisheries Ireland), the elimination of invasive plant species, the provision of an artificial otter holt and replanting of riverine habitat have also taken place.
Smurfit weir to Lansdowne Railway Bridge
The section of substantial extra work from Sherry Fitzgerald to Ballsbridge Motors should be completed in March 2017. The last section of wall on Beatty’s Avenue can then be completed and the riverbed reinstated to Inland Fisheries Ireland specifications. The existing scour mat under Balls Bridge will be lowered and re-laid during late spring/early summer 2017. The substantial extra works on Anglesea Road by the RDS will require a new planning permission. Consultations are currently taking place with all stakeholders with a view to getting planning permission later this year. Works at Embassy House and Herbert Park are complete. Works on Herbert Park Hotel Bridge are currently in abeyance due to stakeholder issues. It is still envisaged, however, that works on this bridge will be completed in 2017. The floodwall is constructed between Zardoz Court and 17A Anglesea Road. The wall at 1 Anglesea Road must be on a piled foundation and it is envisaged to procure a contractor in April 2017 to progress this section. Flood alleviation works are complete between the Dunluce development and the Licensed Vintners Association grounds. Work is currently ongoing in Anglesea Lane. It is envisaged that works up to 133 Anglesea Road will be completed by June 2017. Embankment works are completed in Donnybrook RFC with wall construction works scheduled over the second and third quarters of 2017. Flood works around Smurfit weir is scheduled for end 2017.
All flood works complete. An item of art is to be installed by the river in spring 2016 just downstream of New Bridge commemorating the works.
Lansdowne Railway Bridge to New Bridge
Flood alleviation works are now substantially complete along this section of the river. 335m of floodwall have been constructed as part of this work as well as 25m of flood retaining earth embankment. As in the previous section of works, improvements for pedestrians have been made to the river footpath by Marian College and the public lighting upgraded. Invasive species have been eliminated and replanting with native species is taking place. An area of land downstream of 79 Lansdowne Road will be left for wildlife. Currently, landscaping and replanting works are taking place, with this work scheduled for completion in March 2013.
All flood works complete. Some landscaping is to take place by the site adjacent 79 Lansdowne Road on completion of the parapet wall works to New Bridge.
Bridge Parapets at London Bridge and New Bridge
Following consultations with local residents associations, local representatives and other stakeholders, this scheme is currently going through the planning phase with submissions on the planning applications due for receipt by 3rd December 2012. The planning documentation can be found below. Dependant on planning approval, it would be envisaged to commence this work in March 2013.
The contract for the parapet strengthening works at New Bridge has been awarded. The process of agreeing the contractors proposed design for the post-tensioned cable system is currently being progressed. It is envisaged that construction work will now take place during the summer of 2017.

London and New Bridges Part 8 draft v12.1 FINAL 24-07-12.pdf [15]
Update: The planning permission was passed by Dublin City Council on 4th February 2013 with conditions. Work will start on London Bridge on 8th April and will take three and a half months to complete. Work will involve a road closure at the bridge for vehicular traffic and diversions will be in operation. Pedestrian access will be maintained at all times

Below is a Dublin City Council letter which will be circulated to all residents affected by the closure:
Letter to Residents [18]
Update July 2013: The above works at London Bridge have been extended to 1st September 2013. This prolongation of the road closure has arisen due to delays with relocating existing services (mainly ESB) within the bridge. Moving services requires outages of that service and this is not under our control. There has also been some delay due to the tops of the stone blocks, which form the bridge arches, being higher within the bridge than anticipated. This has required careful grinding down to a height that facilitates the placement of the reinforced concrete strengthening slabs without structurally weakening the arches.
Dublin City Council apologises for any inconvenience caused during the course of these necessary engineering works.
Below is a Dublin City Council letter which will be circulated to all residents affected by the extended closure:
Letter to Residents [19]
Bath Avenue and Londonbridge Road were reopened to traffic on 31st August 2013. The works on London Bridge are now substantially complete with the surrounding areas protected to the National Standard for flood alleviation works. Finishing works are currently being undertaken and pedestrian restrictions on the bridge, which will last until the end of this year, are locally in place to facilitate the placement of the original stone cladding back onto the bridge structure.
Design works and stakeholder liaison are well advanced for New Bridge, also known locally as Herbert Bridge and Lansdowne Road Bridge, and it is hoped to commence these works on completion of works at London Bridge.
Tender documents are being prepared for the placement of post-tensioned cables to the parapet walls, local raising of the walls, strengthening works to the bridge decking and other ancillary works. It is anticipated that these will go to tender this year with a view to works taking place over the summer of 2016.
This work will involve the construction, where necessary, of flood defence walls and embankments, raising of bridge parapets, work on weirs and other ancillary works similar in nature and design to previous schemes on the river. It is envisaged that mitigation works to ameliorate any adverse environmental and social impact will also take place. A consultant has been procured for the design of these works, and flood defence levels have been determined as an output of the River Dodder Flood Risk Assessment and Management Study. Consultation is taking place with relevant stakeholders and it is envisaged that progression to planning will occur in the first half of 2013.
Following the major flood event on the river on 24th October 2011, advanced works are taking place by the Sweepstakes apartments and at the Licensed Vintners Association building off Anglesea Road. These advanced works are scheduled for completion in March 2013.
As part of the Planning and Development Acts 2000 – 2011 and Planning and Development Regulations 2001-2012, Part 8, Dublin City Council is now applying for planning permission to carry out flood alleviation works on both sides of the river Dodder, from Lansdowne Road Railway Bridge to the Lower Smurfit Weir.

Planning permission was granted to this scheme on 1st July 2013 subject to 13 conditions. Construction works have commenced on site at Beatty’s Avenue and are scheduled to sequentially move upstream, with final completion by end 2015. Emergency works at the Licensed Vintners Association off Anglesea Road and the Sweepstakes apartments are complete.
Construction works are ongoing on this phase of works. Flood wall construction is largely complete at Beatty’s Avenue and Dodder View Cottages. The installation of the windows to sections of this wall will take place by November 2015. On structural assessment of the buildings on the opposite bank of the river to Beatty’s Avenue, extra walls have been designed and are being constructed for the section from Sherry Fitzgerald to Ballsbridge Motors. These substantial extra works will delay the final completion date. It is envisaged that this extra section of works will be completed by summer 2016. Works will then commence on lower the floor of the Balls Bridge scour mat. Works by Embassy House, including an extra section of wall strengthening works, are largely complete. Substantial extra works are now required to strengthen the wall on Anglesea Road by the RDS. This will require specialist piling, and tender documents have been drawn up for this work. It is anticipated that construction works along the rear of properties on Anglesea Road will take place during 2016 with completion by the end of that year. Flood works to Herbert Park and Donnybrook RFC are nearing completion. It is currently envisaged that works upstream of Donnybrook Bridge will largely take place in 2017, with the finish in Q2 of that year.
