Flood Relief Scheme Information

The Office of Public Works (OPW) is responsible for leading and co-ordinating the implementation of localised flood relief schemes to provide flood protection for cities, towns and villages, either directly or in association with relevant Local Authorities. This report page identifies the main schemes underway or completed under the OPW flood relief capital works programme. It does not include projects completed by Local Authorities under the Minor Works Scheme or certain other works undertaken directly by Local Authorities within their own works programmes.

Flood Relief Schemes are typically developed as follows:

  • Progress a Flood Relief Scheme - this is where OPW and the Local Authority are preparing a tender brief in order to appoint a Consultant.
  • Stage I - Scheme Development and Preliminary Design
  • Stage II – Planning Process or Public Exhibition / Confirmation
  • Stage III – Detailed Design
  • Stage IV – Implementation/Construction
  • Stage V – Handover of Works

* these schemes are small in size (<€1m) and will be progressed directly by the relevant Local Authorities with full funding from the OPW

Scheme County Proposed Measure Measure Outline
Freshford Flood Relief Scheme Kilkenny Progress the development of a Flood Relief Scheme for Freshford Progress the project-level development and assessment of a Flood Relief Scheme for Freshford, including environmental assessment as necessary and further public consultation, for refinement and preparation for planning / exhibition and, if and as appropriate, implementation. The proposed measure consists of a combination of flow diversion and improved channel conveyance methods, at risk properties would be protected by the construction of two flow diversion channels. Proposed diversion channel 1 being 3.12km long, 3m wide and 1.5m deep and proposed diversion channel 2 being 2.6km long, 3.5m wide for the first 878m and 3m wide for the remainder and 1.5m deep throughout. This option would also require seven 2.1m x 1m box culverts and a weir control at the confluence with the Upperwood watercourse. Two weirs would be removed on the Nuenna River (02WEIR02 at Chainage 1227 and 03WEIR01 and Chainage 1240). Improvement of Channel conveyance on the Upperwood River would involve the lowering of 216m of channel by 0.4m.
Inishannon Flood Relief Scheme Cork Progress the development of a Flood Relief Scheme for Inishannon Progress the project-level development and assessment of a Flood Relief Scheme for Inishannon, including environmental assessment as necessary and further public consultation, for refinement and preparation for planning / exhibition and, if and as appropriate, implementation. The proposed measure consist of walls and embankments with a maximum height of 2.0m along the River Bandon.
Dromod Flood Relief Scheme Roscommon Progress the development of a Flood Relief Scheme for Dromod Progress the project-level development and assessment of a Flood Relief Scheme for Dromod, including environmental assessment as necessary and further public consultation, for refinement and preparation for planning / exhibition and, if and as appropriate, implementation. The proposed measure for Dromod that may be implemented after project-level assessment and planning or Exhibition and confirmation might include; Construction of 368m of new flood defence walls, 263m of new embankments, and a 13m flood gate to defend properties. Flood forecasting. Promotion of Individual and Community Resilience.
Carysfort - Maretimo Flood Relief Scheme Dublin Progress the development of a Flood Relief Scheme for Carysfort - Maretimo Progress the project-level development and assessment of a Flood Relief Scheme for Carysfort-Maretimo, including environmental assessment as necessary and further public consultation, for refinement and preparation for planning / exhibition and, if and as appropriate, implementation. The proposed measure for Carysfort Maretimo HPW that may be implemented after project-level assessment and planning or Exhibition and confirmation might include physical works, such as a series of flood defence walls and five offline storage areas. The result is a reduced flow along the Carysfort Maretimo reducing the length and height of any hard defences required.

Letterkenny Flood Relief Scheme Donegal Progress the development of a Flood Relief Scheme for Letterkenny Progress the project-level development and assessment of a Flood Relief Scheme for Letterkenny, including environmental assessment as necessary and further public consultation, for refinement and preparation for planning / exhibition and, if and as appropriate, implementation. The proposed measure for Letterkenny AFA that may be implemented after project-level assessment and planning or exhibition and confirmation might include physical works. The proposed measure consists of a series of flood walls and embankments, along with the replacement of a footbridge on the Cullion watercourse. The hard defences will provide an SoP of 0.5% AEP for coastal flood events and an SoP of 1% AEP for fluvial flood events. The hard defences have an average height of 1.4m and a total length of 3.8km. The replacement of the footbridge will have a minimum soffit level of 6.5mOD Malin. The proposed measure would also involve extending and raising existing flood defences where they are found to have insufficient height/length to prevent flooding. It is assumed that existing flood defences can be extended, the required extension height and associated base width was determined. The proposed measure relies on flood protection being provided by some existing embankments that were constructed to provide protection to agricultural land, and that were not constructed to the modern engineering standards that would be applied now when providing urban flood protection. A detailed geotechnical structural and stability assessment of the existing embankments was not undertaken as part of the CFRAM study, but should be undertaken as part of the project-level assessment in progressing this measure.
Inistioge Flood Relief Scheme Kilkenny Progress the development of a Flood Relief Scheme for Inistioge Progress the project-level development and assessment of a Flood Relief Scheme for Inistioge, including environmental assessment as necessary and further public consultation, for refinement and preparation for planning / exhibition and, if and as appropriate, implementation.
