The Tolka Flood Alleviation Scheme was initiated in 2002 following a major tidal flooding event in February of that year and a major fluvial flooding event in November 2002, these had estimated return periods of 68 and 100 years. The following table sets out the range of flood event probabilities for which coastal flood extent maps were developed, expressed in terms of Annual Exceedance Probability (AEP), and identifies their parallels under other forms of expression. Flood maps show how likely it is for an area to flood. Increase capacity of the diversion channel between Mackies River and the River Big. The proposed measure consists of a series of flood embankments, walls and improvement of channel conveyance. Construction of 455m of new flood defence walls and 2,435m of new flood defence embankments. The High End Future Scenario (HEFS) flood extents represent a projected future scenario for the year 2100 and As such, it may not show the true peak flood extents. The Mid-North Coast town was inundated with water, with many forced to evacuate. The map is a vector dataset. Maintain existing flood forecasting and public awareness campaign operated by the ESB. Coastal flooding may also be referred to as Tidal flooding in the Maps and Plans. One additional level gauge in Foxford is proposed. The Flood Maps have been developed from detailed engineering analysis and modelling.

It went to construction in 2016 and has been completed. Demountable flood gates will also be required to maintain access. The two storage areas on the Broomhall and Burkeen catchments have a total capacity of approximately 14,800m3.

This layer shows the modelled extent of land that might be flooded by rivers in a severe flood event. The potential effects of climate change have been separately modelled and reported on. Low Probability flood events have an indicative 1-in-a-200 chance (Dublin) or 1-in-a-1000 (Raphoe, Co. Donegal) of occurring or being exceeded in any given year. The Scheme comprises flood defence walls and flood gates on Georges Quay, City Quay and part of Sir John Rogersons Quay adjacent to the Liffey tidal estuary, provides protection against a 200-Year flood (0.5% Annual Exceedance Probability) in the tidal region for approximately 750 buildings. The flow diversion would be located immediately downstream of the bridge where a weir structure would be required to regulate the flow between the proposed flow diversion and the existing channel.

Construction of a new flood defence wall, embankment and floodgates. The proposed further measure for Foynes that may be implemented after project-level assessment and planning or Exhibition and confirmation might include: The Foynes Tidal Flood Alleviation Scheme was initiated in 2014 following major flooding in January and February of that year. The first phase was constructed in 2013 and comprised works to attenuate flood flows upstream of Harmonstown Road Bridge. The Scheme, which comprises, construction of hard defences (embankments & flood walls), culvert removal and the upgrade of three access bridges, is expected to provide protection against an estimated 100-Year fluvial flood (1% Annual Exceedance Probability) and a 200-Year flood (0.5% Annual Exceedance Probability) tidal event for 61 properties. It is expected to provide protection against a 200-Year tidal flood (0.5% Annual Exceedance Probability) and a 100-Year fluvial flood (1% Annual Exceedance Probability) for 246 properties against flooding from the Dungourney and Owenacurra Rivers. The improvement of channel conveyance consists of the removal of a weir on the Ballynerin watercourse. Approximately 2km of new drainage networks and collection systems have been put in place to date. Levels will trigger a warning to be issued to the few properties at risk. The OPW requires that insurers, who are party to the agreement, take full account of the information provided by the OPW when assessing exposure to flood risk for private dwellings and small businesses. the maps should not be used to assess the erosion hazard and risk associated with individual properties The slow response of the River Moy means it is possible to develop a fluvial flood forecasting and warning system for Ballina and Foxford using local level gauges. The Scheme, that comprises mainly of tidal Flood Defences walls and upstream storage in a retention basin upstream of the town, in addition to pump stations, localised defences and repair works to the existing channel banks, to provide protection against a 100-Year flood (1.0% Annual Exceedance Probability) for fluvial and a 200-Year flood (0.5% Annual Exceedance Probability) for tidal for 296 properties against flooding from either fluvial flooding, tidal flooding or both. It provides protection against a 200-Year flood (0.5% Annual Exceedance Probability) for 615 properties against flooding from Waterford Harbour, the River Suir Estuary and the Johns River. An increase in Flood event probabilities are referred to in terms of a percentage Annual Exceedance Probability, or AEP.

These combined measures provide protection to a 1% AEP fluvial event. The potential flood defences would consist of a series of flood embankments (average height of 1.5 m and a total length of 493m), flood walls (average height of 1.2m and total length of 589m) and flood gate (1m at bridge opening at crossing of Emmet Street and Thomond Road). The Scheme, that comprises Flood Defence embankments, berm/channel conveyance improvements, provides protection against a 100-Year flood (1% Annual Exceedance Probability) for 35 properties against flooding from Bandon River.

At risk properties would also be protected by installing a trash screen upstream of a bridge which is susceptible to blockage. This scheme provides protection against 100-Year flood (1% Annual Exceedance Probability) for 25 properties against flooding from the Morell River, the Annagall Stream, the Tobenavoher Stream and the Hartwell River. A Past Flood Event is defined as the occurrence of recorded flooding at a given location on a given date or on a recurring basis. A phase of the Scheme was completed from Causeway Road to the Bull Island Wooden Bridge in Q2 2017. The OPW is committed to providing the best available flood risk information to as wide an audience as possible. The proposed measure consists of a series of walls and embankments. The Scheme, which comprises of the construction of an overflow weir to divert flow to the Broadmeadow River and the improvement of channel and culvert capacity along channel C1/7 of the Broadmeadow and Ward Scheme, is expected to provide protection against a 100-Year flood (1% Annual Exceedance Probability) for 69 properties against flooding from channel C1/7 of the Broadmeadow and Ward Scheme. Embankments are walls of soil or sods that were erected to prevent flood water or high tides from entering land. These maps are focussed primarily (but not entirely) on flooding at seasonally Each community was divided into one or more map tiles depending on area, and maps were produced for each tile.

The proposed further measure consists of building hard defences, at risk properties would be protected by a series of flood embankments on the Burrin River and on the Knocknagee Stream in the Castle Oaks area.

High resolution forecasts are available at Galway Bay and, as part of a coastal flood forecasting system for Galway Bay, could be used to provide warning to the residents of Kinvarra. The potential improvement in channel conveyance would consist of a bridge and culvert replacement of 14m by 1.8m, 10m length arch bridge 4m by 2m, 15m length box culvert. Construct embankments along the right bank of the River Lee and Lower Ballynabrennagh to protect properties in Manor Village, Castlemorris Mews. This scheme is being undertaken by the OPW and will be maintained as part of current duties. It is currently at preliminary design stage, and is expected to go to planning in 2018. The scheme also provided trash screens and flap valves on channels, where appropriate, and repairing a damaged wall at Parsons Lane. High End Future Scenario (HEFS), High+ End Future Scenario (H+EFS) and High++ End Future Scenario (H++EFS) which represent a 0.5m, 1.0m, 1.5m and 2.0m increase in sea level These works increased the capacity of the River Morell as far as its confluence with the River Liffey and provided flood attenuation to 10 properties against flooding from the Morrell River. The December 2015 flooding was in excess of the 1% AEP design standard and so the proposed flood relief works do not protect to this standard, however a number of methods are technically viable and should be considered if extra funding is available to protect to a higher design standard.
