South Campshires Flood Protection Project

The South Campshires between Butt Bridge and Sir John Rogerson’s Quay are a
section of the original Dublin docklands quay wall which is lower than the average wall height  along the north or south quays. This area is vulnerable in the event of
exceptionally high tides in this tidal zone of the River Liffey. The flood cell includes significant business, retail and densely populated residential Area.

  • The overriding purpose of the South Campshire Flood Protection Project (SCFPP) is to provide an increase in protection against coastal flooding along the south city quays from Butt Bridge to approximately 50m east of the Samuel Beckett Bridge, having regard to the requirements of current users of the area

  • Dublin City Council applied to an Bord Pleanala for Planning Approval to construct the South Campshire Flood Defences on 12th. July 2011 in accordance with Section 175 of the Planning & Development Act 2000. The Application was accompanied by an Environmental Impact Statement and followed wide ranging consultation.

  • Full details of the Project were made available during the statutory period of public consultation.

  • An Bord Pleanala approved the proposal, subject to certain conditions, on 18th. May 2012

  • Following a procurement process, Dublin City Council has, on 23rd. July 2012, engaged Consulting Engineers, URS Ireland, to complete the detailed design, complete the tender process and supervise the construction of the works.

  • The protection will, for the most part, consist of a new wall which will be approximate 800mm  to 900mm high, depending on its location, and have a number of openings to allow access to the Campshires, pedestrian bridges and walkway.

  • The flood protection takes different forms at several sections over its length including high quality concrete finish wall, granite wall, raised parapets and waterproofing of existing buildings along the Campshires. Sections of the flood protection wall are staggered throughout the length of the Campshires to provide pedestrian permeability and integrate and improve the layout and landscape of the Campshires

  • Due to the location of the proposed Flood Defences, and in consultation with Dublin City Council, the project incorporates a two way segregated cycle lane from Butt Bridge to connect to the recently completed cycleway at the new Beckett Bridge, together with a new or upgraded footpath over the full length of the project

  • URS Ireland and DCC Project Management Office made a presentation on the project to Dublin City Council South East Area Committee on the 10th of September 2012 and will maintain continuous consultation with local residents and business interests through the design and construction phases.

  • Construction is expected  to begin in Q4 2013 and be completed by Q4 2014.

Clontarf Promenade Development and Flood Defence Project

Update 4th March 2013

Since the decision was made on 5th. December 2011 not to proceed with the proposed Clontarf Flood Defence Scheme, Dublin City Council’s Environment & Engineering Department has been working with the Clontarf Residents Association and Clontarf Business Association.

Arising from these discussions, a workshop was held on 23rd. October 2012, attended by these Groups and by DCC and facilitated by an agreed Independent Facilitator. An Agreed Report was produced by the Facilitator and this will be placed on the websites of Dublin City Council and the Clontarf Residents and Business Associations shortly.

In relation to next steps, it was agreed at the Workshop that a small working group representing a multi-disciplinary team from DCC, together with the local residents and business groups, would be put in place to examine what options were available that would adequately address the coastal flood risk, while being also acceptable to the local interest groups. This was set out in the following agreed statement:

“Dublin City Council, The Clontarf Residents Association (CRA) and Clontarf Business Association (CBA) thank Mr. George Ryan, independent chair for completing his report on a joint workshop and intend to set up a joint working group to explore options for a Clontarf Promenade Development and Flood Defence Project based on the recommendations of the workshop” The first meeting of this Joint Working Group was held on 21st February 2013 and further meetings are planned.

Dollymount Promenade and Flood Protection Project

The DFPP is part of the S2S Project which was included as an objective of the current Development Plans for Dublin City Council, and Dun Laoghaire Rathdown County Council and has also been included in the Dublin Docklands Development Authority’s Masterplan and the Dublin Transportation Office’s Platform for Change. The completion of S2S is also a policy within the Governments’ Cycle Policy Framework 2009.

The overriding design parameter of the project is the provision of a promenade, cycleway and flood defence.  Coastal Flood Protection measures have also been included as an integral part of the design of the Dollymount Promenade & Flood Protection Project.

This project is currently in the detailed design stage. The Environmental Impact Statement (EIS) was submitted in June 2009 to An Bord Pleanála for Planning Approval. Subject to funding, the project will commence in the summer of 2010.

The design life for the proposed promenade will be 120 years. However, for the design of coastal protection structures a national design standard of a return period of 200 years should be adopted for the design. The extreme high water level (based on Dublin Port) for a return period of 200 years is predicted at a level of +3.13mOD (Malin) for a base year of 2005. According to Dublin Coastal Flood Protection Plan (DCFPP) climate change / sea level rise recommendations, an annual sea level rise of 4.15mm/year should be included in all future designs for flood defence or other structures. This includes an allowance of 0.3mm/year for land subsidence.
Indicative proposals of such defences have been included on the preliminary design drawings.

 

Sandymount Coastal Flood Defence Scheme

Sandymount Coastal Flood Defence Scheme currently consists of two phases. Phase 1 relates to the promenade wall from Gilford Ave to St. Alban’s Park. Phase 2 relates to the seawall between Gilford Ave and Seafort Ave.
 
Phase 1 consists of raising the existing wall located at the back of footpath by up to 360mm and the installation of floodgates in the vehicular and pedestrian accesses along the promenade. It involves removal of one pedestrian and one vehicular entrance and reducing the size of some of the other openings. Phase 1 will be entering a planning process in the coming months and commencing construction in 2017.
 
Phase 2 is currently at preliminary design stage with coastal defence options being reviewed. Extensive Environmental Impact Assessments will have to be carried out due to Dublin Bay labeled a Special Area of Conservation. It is at least 3-4 years from construction.
 
Flood defences have already been constructed opposite Marine Drive with the permanent closure of a pedestrian opening beside Merrion Gates.

DCC Presentation on Sandymount Coastal Flood Defence Scheme - Phase 1 given at the Sandymount Hotel on July 21st 2016.
