Public awareness .
Raised road level over a length of 20m along the north of Portumna Harbour.
Vertical Sector Gate to act as a barrier to flooding across the entrance to Portumna Harbour to prevent the inlet receiving flood water directly from the Shannon. The structure would consist of a set of gates which could be closed after a flood warning, and open during normal conditions to allow the passage of boats.

| Askeaton Flood Relief Scheme |
Limerick |
Progress the development of a Flood Relief Scheme for Askeaton |
Progress the project-level development and assessment of a Flood Relief Scheme for Askeaton, 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 Askeaton that may be implemented after project-level assessment and planning or Exhibition and confirmation might include:
Construction of 968m of new flood defence walls and 405m of new flood defence embankments;
Increased conveyance from the tributary to the River Deel. This tributary is located upstream of the town centre and flows into the River Deel from the West. This involves widening and deepening approximately 30m of the tributary channel and replacing 130m culvert linking the tributary to the main channel. The replacement culvert would flow underneath the road and the Aeroboard factory premises, and requires a new headwall at the upstream extent to prevent overtopping. The existing arterial drainage scheme needs to be maintained as part of this option. |
| Listowel Flood Relief Scheme |
Kerry |
Progress the development of a Flood Relief Scheme for Listowel |

The proposed measure for Listowel that may be implemented after project-level assessment and planning or Exhibition and confirmation might include:
Increase the height of 0.9km of existing embankments and raise approximately 30m of road in order to eliminate flood risk to the properties within the 1% AEP event.
Flood forecasting to allow the community/local authority to ensure that the amenity walkway along the river is cleared and appropriate pedestrian diversions are in place.
Existing maintenance regime for the Feale along with a maintenance programme for the improved and existing defences. |
| Athleague Flood Relief Scheme |
Roscommon |
Progress the development of a Flood Relief Scheme for Athleague |
Progress the project-level development and assessment of a Flood Relief Scheme for Athleague, 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 Athleague that may be implemented after project-level assessment and planning or Exhibition and confirmation might include:
Construction of a 190m new flood defence wall, 340m embankment and a floodgate to defend properties.
The introduction of the above flood defences and their location will interfere with existing drainage. Current flood surface water drainage flows directly in the Silver Stream. During flood events the Silver stream acts as a flow path for flood waters from the River Suck. A series of sewers, non-return valves and a pumping station will be required to ensure that pluvial flooding is also reduced. This would have additional benefits which are not captured within the CFRAM process. The costs of the required upgrade sewer have not been included in the costing for this measure. |

Progress the project-level development and assessment of a further fluvial Flood Relief Scheme for Foynes to augment the existing coastal Scheme, including environmental assessment as necessary and further public consultation, for refinement and preparation for planning / exhibition and, if and as appropriate, implementation. The proposed further measure for Foynes that may be implemented after project-level assessment and planning or Exhibition and confirmation might include:
A 1.26km long quay/sea wall is required to defend the AFA from the 0.5% AEP event. Floodgates would also be required at a number of locations along the wall to maintain access to the port. It is important to note that the exact positioning of the wall would need to be determined during detailed design stage following consultation with all the relevant stakeholders, as there are a number of pipeline and other utility services within the working corridor of the proposed defence wall.
An improved outfall structure is required on the Foynes River where it discharges at the quay, to prevent tidal ingress. It was noted at the Public Consultation Day in Foynes during the Draft Flood Mapping stage that "the sluice gate at this location is not currently maintained and there is silt build up, maintaining and removing the silt would help reduce flood risk". Therefore, this measure should be an improved sluice or flapped outfall arrangement with an accompanying active inspection and maintenance regime.
A 37m long flood defence wall with a typical height of 0.6m above ground level.
A 85m long flood embankment with a typical height of 1m above ground level.
The existing arterial drainage maintenance scheme will need to be maintained as part of this option. |
