These hard defences would protect properties from the 1% AEP fluvial event and with estimated an average height of 1.56m and a total length of 1.31km. Local authorities are charged with responsibility to maintain Drainage Districts. The Scheme, which comprises construction of demountable flood defences at the underpass along with localised embankments is expected to provide protection against an estimated 100-Year flood (1% Annual Exceedance Probability) in the fluvial region and the 200-Year flood (0.5% Annual Exceedance Probability) tidal event for 37 properties. Each community was divided into one or more map tiles depending on area, and maps were produced for each tile. The maps do not, and are not intended to, constitute advice. The floods are shown as polygons. Localised widening of the River Boherroe from a 4m to a 5.5m wide channel along the 150m reach between the Bridge road bridge and R556 road bridge. Drainage Districts were carried out by the Commissioners of Public Works under a number of drainage and navigation acts from 1842 to the 1930s to improve land for agriculture and to mitigate flooding. When required during a fluvial event and at high tidal water levels the two Pumping Stations would extract any flood water that cannot be discharged to Carlingford Harbour as normal. Bogland and other lands are identified separately. The Dunfanaghy pier would require approximately 850m2 of raising by an average of 900mm.

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. A flood study is a technical project that identifies flood behaviour such as depth, velocity and extent across the floodplain. The potential improvement in channel conveyance would also consist of in channel excavation - 800m3 of excavated materials and underpin minor channel footbridge - 6m to depth 0.3m. The floods are shown as polygons. They may, however, also be of use to the public, Local Authorities and other parties as indicative maps of flood-prone and erosion-prone areas for a range of purposes, including raising awareness of flood and erosion hazard and risk, preparedness and response planning for flood and erosion events, assisting in planning and development decisions, etc. This interim scheme has been complemented by a more comprehensive scheme, which has been substantially completed, to provide a higher standard of protection and protect more properties in the town. The Environment Agency identified flood risk areas in their preliminary flood risk assessment (PFRA) published in 2018. The OPW carried out a survey of these embankments in 1939 and 1940 as part of the work of the Browne Commission. 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.

This layer shows the coastline as digitised from the OSi colour aerial ortho-photography from 2000. Emergency construction started immediately following the November 2002 event with the majority of the works completed between 2003 and 2009. River reaches that have been modelled are indicated by the CFRAM Modeled River Centrelines dataset. The flood alleviation works at Leighlinbridge were initiated in 2010 following flooding in 2009 which overwhelmed existing defences, and were constructed from 2011 to 2012. Installation of a simple flood-forecasting unit, including an addition of telemetry to an existing hydrometric gauge to send warning messages when water level reaches a specified trigger point. Benalla 25C 25C is not accounted for and needs to be considered separately. Construction of an embankment, 325m long with an average height 1-1.5m above ground level. The Scheme comprises of flood defence walls, embankments, localised floating barriers and pumping stations for storm water that would otherwise accumulate behind the defences. This combination would protect to the 1% AEP fluvial flood event and 0.5% AEP coastal flood events. The Present Day Scenario is referred to as the Current Scenario in the maps and reports. This service does not tell you: how likely it is that an individual property will flood about flood risk from sources such as blocked drains and burst pipes Other ways to get this information. The Wad River Flood Alleviation Scheme was initiated in 2009 following two major flood events in this catchment in August 2008 and July 2009. The scheme works included construction of extra flow capacity to three bridges and the replacement of a further bridge.
