Some residents of the NSW town of Taree have started returning to clean what's left of their properties damaged by flooding. The Present Day maps were generated using methodologies based on historic flood data, without taking account of potential changes due to climate change. The Glashaboy Flood Relief Scheme was initiated in 2014 following major flooding in 2012. 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. 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. Move mouse over station for more data. Flood walls (average height of 1.3m and a total length of 184m). In addition to the maintenance of the existing scheme, additional measures are required to ensure full protection is provided. The maps include an increase of 2000mm in sea levels above the current scenario estimations. The works comprise the construction of a flood relief wall around Derrymullan, installation of penstock and flood gates and provides protection against a 1% AEP (100 year) fluvial event from the Deerpark River for 135 properties. 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. Rainfall records have been toppled in some Mid North Coast areas, including Taree where 305 millimetres fell in the 24 hours to 9am on Thursday. The proposed measure would protect at risk properties by a series of hard defences consisting of flood embankments and walls. to inform the assessment of flood risk to individual sites or properties, the detailed assessment of flood risk to existing coastal infrastructure, the detailed evaluation Printable maps have been created for the Present Day, Mid-Range Future Scenario (MRFS) and High End Future exceeded in any given year. Installation of a simple flood forecasting unit, which includes the addition of telemetry to an existing hydrometric gauge to send warning messages when water level reaches a specified trigger point. Fluvial warnings for Foxford and Ballina should be based on a level to level system using existing gauges and re-instated Foxford gauge. only takes into account coastal flooding from a combination of tide levels and storm surges; any significant impact and erosion related data presented on these maps are copyright of the Office of Public Works. The floods are shown as polygons. The proposed measure consists of a series of flood embankments and walls.

The scheme also provided trash screens and flap valves on channels, where appropriate, and repairing a damaged wall at Parsons Lane. Further embankments were placed along the Castle Stream with channel deepening/widening also carried out. This dataset shows areas that have been or are planned to be surveyed as part of the Pilot Coastal Monitoring Survey Programme - LiDAR The Scheme, comprises flood defence walls and embankments along the Rye Water and flood defence walls along the Silleachain river, provides protection against a 100-Year flood (1% Annual Exceedance Probability) for 50 properties against flooding from the Rye Water and Silleachain rivers. The OPW carried out a survey of these embankments in 1939 and 1940 as part of the work of the Browne Commission. The Act was amended on a number of occasions, e.g. These works were undertaken by Limerick City Council with funding from the OPW and are maintained under local authority duties. Data has been produced for catchments greater than 5km2 in areas for which flood maps were not produced under the National CFRAM Programme and should be The user of these maps shall be deemed to have agreed to, and unconditionally accepted all of these statements and conditions. The low benefit-cost ratio is due to the relatively low risk to properties during the 1% AEP fluvial flood event in Trim, resulting in a small benefit value. 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. Layer Information Construction 1,799m of new flood defence walls, 846m of new embankments and a 2m floodgate. You are required to read the Terms and Conditions. Emergency construction started immediately following the November 2002 event with the majority of the works completed between 2003 and 2009. Memorandum Of Understanding Between OPW and Insurance Ireland. The Scheme, that comprises widening and deepening of the river channel, the construction of walls, embankments and culverts, underpinning of Bray Bridge, river regrading, soil nailing and erosion protection, provides protection against a 100-Year flood (1% Annual Exceedance Probability) for fluvial flooding and a 200-Year flood (0.5% Annual Exceedance Probability) against tidal flooding for 658 properties. In all cases, derived works should include a reference to floodinfo.ie, and to the disclaimer above. The flood extent and depth maps are suitable for the assessment of flood risk at a strategic scale only, and should not be used to assess the flood hazard and risk associated with individual properties or point locations, or to replace a detailed flood risk assessment. Mill Race Watercourse - Two sluice gates capable of retaining coastal flood water to a level of 5m AoD Malin are required on the Mill Race watercourse. The outputs of this study are NOT considered suitable A tidal flood forecasting and warning system to include high resolution forecasts for Newport is to be developed. Upgrading existing culvert downstream of the Kilkee East watercourse. These embankments were created by landowners to reclaim land from rivers or the sea, typically in the 19th century. Local Risk Information. Cars line up on the roadside near Taree service centre, waiting for The highway to reopen after being inundated by flood waters (SMH) In and around Sydney: At Cattai, Wisemans Ferry Road is closed across the Cattai Creek bridge. The proposed measure consists of improvement of channel conveyance in two areas along the Termonfeckin watercourse. These hard defences would protect to the 1% AEP flood event with an average height of 0.9m and a total length of 2.4km.

Layer Information The Present Day Scenario is referred to as the Current Scenario in the maps and reports. Detailed joint probability water level and wave climate condition tables have been produced for each CAPO for the present day scenario, Mid-Range Future Scenario (MRFS), the effect of existing coastal defence structures from the erosion hazard and risk assessment. To create a report zoom and click on a location of intrest - a symbol will Taree Regional Airport; Development Sub-menu. From drone video footage, and images captured by the public, it can be seen that there were significant floods in north Port Macquarie, at Settlement Point (0.5 - 1.5m), at Shoreline Drive, and at The Anchorage. The possibility of underpinning Arklow Bridge and the possible removal of a pinch point in the channel downstream of Arklow Bridge are also being considered. The map was created using groundwater levels measured in the field, satellite images and hydrological models. 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. Full details are available here. These combined measures provide protection to a 1% AEP fluvial event.

The works comprise flood defence walls and provides protection against the then view of the 1% AEP (100 year) fluvial event from the Abbey River for 134 properties. The High++ End Future Scenario (H++EFS) maps represent a projected future scenario for the end of century (circa 2100) and include allowances for projected future changes in sea levels and glacial isostatic adjustment (GIA). 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. The Embankments layer identifies the embankments that form part of Land Commission Embankments. A flood risk assessment was completed and a flood relief scheme proposed for the AFA. This would have additional benefits which are not captured within the CFRAM process. The Irish Coastal Protection Strategy Study (ICPSS) erosion hazard mapping is for strategic The event is derived from available flood information documentation including This data is an update of the extreme water level estimation undertaken as part of the Irish Coastal Protection Strategy Study (ICPSS) between 2004 and 2013. This measure does not provide protection downstream of the Church Street Bridge. The survey was undertaken from a helicopter, using a gyro-stabilised high quality digital camera system. A Government Task Force on Emergency Planning is currently drafting a Strategic Emergency Management (SEM): National Structures and Framework document. 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. The two culverts will be upgraded to 1.5m diameter pipes in order to convey the 1% AEP fluvial flow within the channel. The hard defences will have an average height of 1.1m (reaching a maximum height of 2m) and a total length of 830m.

The proposed measure for Old Connaught and Wilford 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 (flood embankments and walls) in conjunction with, a culvert upgrade and channel dredging at the Dublin Road adjacent to St Brendans School, and a flow diversion channel on the Old Connaught River. The River Fergus Lower (Ennis) Certified Drainage Scheme commenced construction in 2013. The Commissioners of Public Works in Ireland (the "Commissioners") have developed the National Indicative Flood Mapping Data for the Republic of Ireland as part of the National Indicative Flood Mapping Project (2019-2020). The OPW is required to maintain drainage schemes under sections 37 and 38 of the Arterial Drainage Act, 1945. They are also commonly referred to in terms of a return period (e.g. The Winter 2015/2016 Surface Water Flooding map shows fluvial (rivers) and pluvial (rain) floods, excluding urban areas, during the winter 2015/2016 flood event, and was developed as a by-product of the historic groundwater flood map. A demountable flood gate will be required across the old railway line and should be tied into the new flood defence wall and embankment. include allowances for projected future changes in climate and glacial isostatic adjustment (GIA). The proposed flood defences would include sheet piles to counter the underground flow paths which exist between the river and flood receptors and consist of a series of flood embankments (average height of 1.25m and a total length of 667m) and retaining walls (average height of 1.5m and a total length of 300m). 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. This layer shows the modelled extent of land that might be flooded by rivers in a very extreme flood event. Hydrometric monitoring is proposed in Ballingeary to improve confidence in the design flows, noting that is has been reported that recent floods exceeded the level and extent of the predicted 1% AEP.

The Lower Morrell (Straffan) Flood Relief Scheme was initiated in 2010 following major flooding in 2009. Flood Project Floodplain Risk Management Study Lansdowne Floodplain Risk Management Study Completed Publication date: 19/11/2014 works potentially protecting the coastal floodplain are not taken into account. Flooding from other sources may occur and areas that are not shown as being within a flood extent may therefore be at risk of flooding from other sources. This is also referred to as an Annual Exceedance Probability (AEP) of 0.5%. The pilot study includes a detailed building survey to identify all potential flow paths through the affected properties and the type of foundation and floor in affected property along with other factors which may affect the viability of any proposed measures. 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 flood study is a technical project that identifies flood behaviour such as depth, velocity and extent across the floodplain. A phase from the Malahide Road to Raheny Village is at design stage by Dublin City Council and, subject to funding, will progress to submission for planning approval. 200 to 1) of the event occurring in any given year. The OPW is required to maintain drainage schemes under sections 37 and 38 of the Arterial Drainage Act, 1945. A third phase downstream of Raheny village is planned for construction thereafter again subject to funding and planning approval. Within Dublin City the scheme, comprises flood defence walls, embankments, channel conveyance improvements, a new raised bridge in Griffith Park and a pumping station adjacent to Drumcondra Bridge and Botanic Avenue for storm water that would otherwise accumulate behind the new defences.

For up-to-date information on local roads, check with your local council. The Morrell River (Turnings Area) Flood Relief Scheme was initiated in 2001 following major flooding in November 2000, and was constructed from 2002 to 2003. Channels and lakes were deepened and widened, weirs removed, embankments constructed, bridges replaced or modified and various other work was carried out. The proposed measure relies on ood 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 ood protection. The proposed measure for Lucan to Chapelizod 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 (flood embankments and walls). This represents the worst case scenario as any flood defences potentially protecting the coastal floodplain are not taken into account. The purpose of the Flood Maps is not to designate individual properties or point locations at risk of flooding, or to replace a detailed site-specific flood risk assessment. 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. ); identify areas of recovery or accretion; support the development and/or updating of numerical coastal flood, even though at present a flood defence is protecting them. Rainfall flooding is referred to as Pluvial flooding in the Maps and Plans. 3 beds, 1 bath, 960 sq. The Carrigaline Flood Relief Scheme has been under review to confirm the technical aspects and viability, and, subject to outcomes, will then progress to Outline Design and Planning. The potential measure would protect at-risk properties against the 1% AEP Fluvial flood event by flood defences. This layer shows the modelled extent of land that might be flooded by the sea in a very extreme flood event. 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.

PURPOSE OF THE MAPS This will require a revised sectoral plan to be prepared by the OPW, covering the flood risk management sector. Each polygon has info on the data source, and the area of the flood. The proposed measure consists of a series of flood walls to protect to the standard of a 1% AEP fluvial flood event. The Environment Agency identified flood risk areas in their preliminary flood risk assessment (PFRA) published in 2018. The Wad River Flood Alleviation Scheme was initiated in 2009 following two major flood events in this catchment in August 2008 and July 2009. Installation of a simple flood forecasting unit, including a new hydrometric gauge with water level monitoring and telemetry to send warning messages when water level reaches a specified trigger point. A third City wide event in October 2011 again caused significant flooding in this catchment. Natural online storage areas, balancing pond and natural flood plain areas. Promotion of Individual and Community Resilience. Extreme water level estimates are provided for present day sea levels as well as the Mid-Range Future Scenario (MRFS), 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, respectively.
