Flood Risk Management

The Office of Public Works (OPW) is the lead State body for the coordination and implementation of Government policy on the management of flood risk in Ireland. The OPW is also the national authority for the implementation of the EU Directive on the Assessment and Management of Flood Risks [2007/60/EC]. 



The OPW has responsibility for leading and co-ordinating the implementation of the National Flood Risk Policy approved in 2004 which involves the development of a planned programme of prioritised feasible works, with a greater emphasis for non-structural measures.

The OPW coordinates the sectoral activities of other Departments and Agencies through the Inter-Departmental Flood Policy Coordination Group and the Shannon Flood Risk State Agency Co-Ordination Working Group.

On 3 May 2018, Minister of State with special responsibility for the Office of Public Works (OPW) and Flood Relief, Kevin ‘Boxer’ Moran T.D. published 29 Flood Risk Management Plans to address flood risk in Ireland.

A new website www.floodinfo.ie now provides access to the Plans and Maps developed by the OPW and information on flood risk management in Ireland.

Through the interactive Flood Plans Viewer, users can view a summary of the flood risk management measures as set out in the Plans. The Flood Maps Viewer allows users to access flood mapping data for the areas assessed.

The 29 Plans and all supporting documentation are available to download in the Publications section of this website. Users can also access key policy reports, county summaries and other useful material.

The OPW is responsible for a total of 11,500km of river channel, including approximately 800km of embankments, which form part of the Arterial Drainages Schemes completed since 1945.

The OPW keeps these under proper repair and in an effective condition through an annual maintenance programme. Consent is required from OPW 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.
