The Office of Public Works, through its Catchment Flood Risk Assessment and Management (CFRAM) Programme, carried out the largest ever flood risk study in Ireland to date, undertaking a detailed engineering assessment of 300 areas or communities believed to be at significant risk of future flooding.
In 2018, Minister of State with special responsibility for the Office of Public Works (OPW) and Flood Relief, Kevin ‘Boxer’ Moran TD published 29 Flood Risk Management Plans to address flood risk in Ireland.
These plans include 118 additional flood relief schemes and are available to download, with supporting documentation, from the Publications section of www.floodinfo.ie.
Since 1996, 42 major flood defence schemes have been constructed throughout the country, protecting 9,500 properties. A further 8 new schemes are currently under construction with a further 26 schemes at design/development. All completed schemes have performed well in protecting the towns and communities concerned.
Minor Works and Coastal Erosion
The Office of Public Works Minor Flood Mitigation Works and Coastal Protection Scheme
provides funding to local authorities to undertake minor flood mitigation works or studies, costing less than €0.75 million each, to address localised flooding and coastal protection problems within their administrative areas.
The 11,500km of river channel, including approximately 800km of embankments form part of the Arterial Drainages Schemes completed since 1945.
These are kept under proper repair and in an effective condition through an annual maintenance programme. Consent is required from Office of Public Works to construct, replace or alter a bridge or culvert.
A prepared and appropriate response from the relevant emergency response bodies (principally the local authorities, Gardaí and health services) can mitigate the potential negative impacts of major flood events.
The public can also reduce the impact of floods by being aware of the flood risks and potential impacts and being prepared to take action if and when a flood occurs.
The OPW has also developed the following applications website to host maps of completed flood defence schemes and arterial drainage schemes and to provide access to the draft Flood Risk Management Plans:
The OPW has prepared a number of technical specifications and guidance notes that it makes use of when commissioning work, such as the design of flood relief schemes and the preparation of flood maps. These may be applied as relevant by other authorities where there is an intention to work with the OPW.
