The proposed measure for Wicklow, Ashford and Rathnew that may be implemented after project-level assessment and planning or Exhibition and confirmation might include physical works, such as a series of hard defences, storage and improvement of channel conveyance. The Channels layer identifies the watercourses forming part of Arterial Drainage Schemes. The proposed measure consists of diverting surface water flow originating from the hills to the north and west of Raphoe by the creation of an open channel to collect and divert flows away from the town. Information on new and past flood events can be, and is, submitted from a variety of sources (government, private and individuals) for inclusion as it becomes available. The proposed measure for Birr that may be implemented after project-level assessment and planning or Exhibition and confirmation might include; The Mulkear River (Cappamore) Certified Drainage Scheme was constructed from 1998 to 2002. This map was made using satellite images (Copernicus Programme Sentinel-1), field data, aerial photos, as well as flood records from the past. The flapped gates on the Sluice River at Portmarnock Bridge prevent the propagation of high tides upstream of this bridge. Flood protection in the benefiting lands was increased as a result of the Arterial Drainage Schemes. The outputs of this study are considered suitable to inform the assessment of flood risk at a community level. The FEM-FRAMS was initiated in 2008 and included assessment of Laytown, Bettystown and accompanying coastal areas. Full details are available here. The purpose of the Flood Maps is not to designate individual properties at risk of flooding. Hard Defence would also include a 253m long section of raised road where space is restricted for walls or embankments. in Phase 2 of the Irish Coastal Wave and Water Level Modelling Study (ICWWS 2018). is not accounted for and needs to be considered separately. Culvert; Upgrade the existing Kilclooney Road Bridge on the River Deerpark; Regarding of the riverbed upstream and downstream of Kilclooney Road Bridge to maximize efficiency of the upgraded structure; Public Awareness, Flood Forecasting will also be required as part of this measure; The West and East Atlas channels need to be maintained to ensure their full capacity can be utilised in a flood event.

The Minister and Land Commission were exempted from any responsibility for maintenance of land sold by the Land Commission under Section 10 of the Land Act, 1965, and this responsibility falls on the current landowners, in line with the provisions of the Land Acts. 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. This will fit into the height of the existing river walls and maintain some visual connection. Following approval of the Climate Change Adaptation Framework key sectors and Local Authorities are required to develop sectoral and local adaptation plans. Consequently, there will be areas where no erosion to transpose EU Regulations and Directives such as the EIA, SEA, and Habitats Directives and the Aarhus Convention. over 2m width). When the drainage system is surcharged rainwater overflows into these storage areas and is released by gravity when the storm subsides and water levels in the drainage network abate. Freeboard for all walls and raised river banks is in excess of 0.3m above the peak flood level. Such was the case in the Manning catchment in 1978. The proposed measure consist of flood walls and embankments to protect vulnerable properties in Inchigeelagh.

The Scheme, comprises flood defence walls and embankments along the Morell River, the Annagall Stream, the Tobenavoher Stream and the Hartwell River. The purpose of the schemes was to improve land for agriculture, to ensure that the 3 year flood was retained in bank this was achieved by lowering water levels during the growing season to reduce waterlogging on the land beside watercourses known as callows. However, there is a history of extensive flooding, which could not be replicated in the CFRAM Study Mapping. Land use management would be applied to the catchments in order to mitigate any adverse effects from constructing the hard defences on a protected species. This system would provide the ability to inform managing authorities and the public of the potential for failure or overtopping of flood defence structures and to trigger emergency response plans. Downstream of the existing embankment, the existing wall will need to be assessed and will need to provide a flood defence function up to a level of 5.8m OD. This system would provide the ability to inform managing authorities and the public of the potential for failure or overtopping of flood defence structures and to trigger emergency response plans. The scheme, that comprised improved channel conveyance, raised wall, culvert bypasses and screen upgrades, provides protection against a 1:50 to 1:100 year flood event (1-2% Annual Exceedance Probability) for 40 plus properties, against flooding from the Carysfort Maretimo Stream. The Scheme comprises of a combination of embankments, walls, channel straightening, bridge underpinning and localised dredging and is expected to provide protection against a 100-Year flood (1% Annual Exceedance Probability) for 80 properties against fluvial flooding. This is because the flood risk in the Milltown AFA is relatively low. The Skibbereen Flood Relief Scheme was initiated in 2011 following major flooding in 2009.
