Background Information

The Flood Relief Scheme involves two scheme areas:

  1. Dundalk and Blackrock
  2. Ardee

Dundalk (Dún Dealgan) is the county town of County Louth, Ireland. It is the administrative capital of the county and is close to the border with Northern Ireland, forming part of Ireland’s Ancient East. Dundalk lies on the Castletown River, which flows into Dundalk Bay on the East Coast of Ireland.  The Castletown River Estuary and Dundalk Bay is a Special Protection Area (SPA), as well as being a Special Area of Conservation (SAC). The bay is also a Proposed Natural Heritage Area, further reinforcing the environmental value and sensitivity of the area.  Blackrock is a seaside village to the south of Dundalk with a population of approximately 4,000.  Blackrock draws visitors to its’ beach and promenade, with views looking out over Dundalk Bay and towards the Cooley Mountains.

Ardee lies on the banks of the River Dee. Ardee is equidistant between the towns of Dundalk and Drogheda and has undergone continuous development over several decades.  The flood relief scheme for Ardee is a sister project being run in tandem with Dundalk/Blackrock to provide benefits to all of the local communities as soon as possible.

As part of the Government’s National Development plan to 2030, €1.3 billion has been committed to the development of flood relief measures across Ireland. Following on from this commitment, a steering group was established between the OPW and Louth County Council to progress a flood relief scheme to alleviate the risk of flooding for communities of Dundalk/Blackrock & Ardee. In Summer 2020, a Joint Venture (JV) between Binnies (B) and Nicholas O’Dwyer (NOD) was appointed as Engineering Consultants, to develop a scheme that is socially, environmentally, economically, and technically acceptable.

Benefits of Scheme

Dundalk and Blackrock have suffered many flooding events, most notably in 2008, 2014, 2016 & 2020, whilst they are furthermore at significant risk of coastal flooding. With the future flood risk increased by climate  change  and  the  areas  natural low-lying topography, calls  for  a  sensitive flood relief scheme  to  be constructed  to reduce the  risk from future flood events were set  out  in the Catchment Flood  Risk  and Management Study (CFRAM) published by the Office of Public Works (OPW) in 2018.The development of any proposals will consider the impact on any neighbouring communities in line with requirements of the EU Floods Directive.

To address flooding issues nationally, the Office of Public Works (OPW) commissioned and completed Catchment and Flood Risk Management (CFRAM) studies covering the entire country. The North Western – Neagh Bann CFRAM Study, included Dundalk, Blackrock & Ardee, and was completed with support from various County Councils, including Louth County Council. An output of the study identified flood risk areas, including Dundalk/Blackrock & Ardee, and the associated impacts of flooding. A link to these reports can be found here. The plan also sets out the measures and policies to be pursued, in order to achieve the most cost effective and sustainable management of flood risk.

Following the launch of the flood relief programme by the OPW in 2018, Binnies / Nicholas O’Dwyer Joint Venture (B/NOD JV) were appointed, by tender competition off the OPW's framework, in August 2020 to complete a detailed project level engineering assessment for Dundalk/Blackrock and Ardee. The assessment will involve identification of appropriate flood risk alleviation measures and preparation of detailed design drawings and documents. B/NOD will carry out the appropriate Environmental Assessments including the Environmental Impact Assessment Report (EIAR) and the Natura Impact Statement (NIS), where required under the relevant legislation.

The works are likely to involve improvement of channel conveyance (maintenance & culvert upgrade), potential storage ponds, and hard defences (walls & embankments).  All works will be carried out in accordance with the project programme and the public will be fully informed in advance of any potential disruption.


Where possible, the scheme intends to capitalise upon the potential flood defences from Blackrock to Bellurgan as a potential corridor for a section of the Great Eastern Greenway from Belfast to Dublin. This presents an opportunity to provide a significant piece of infrastructure which has the potential for huge recreational, tourism and financial benefits for the area.

Latest News



Public Information Day 2 -

Ardee Emerging Flood Relief Options - CLOSED

Updates / November 25, 2022

This second Public Information Day is held on 25th November to present the emerging options developed to date and to gather your opinions and concerns to inform the selection of a preferred scheme. A questionnaire will be available for you on the day and if you cannot join us a copy of the questionnaire will be available on this website as well as supporting maps and information. Closing date for consultations and questionnaire submissions is 9th December 2022.



Updates / June 29, 2022

The CCTV surveys are ongoing and awaited to be completed in short term. Input from Geotechnical Investigation (GI) Surveys will also be required at a later stage of the Project. GI Surveys are intrusive and required to help us understand the geology and groundwater of the Study Area.


Environmental Assessment 

Updates / June 29, 2022

Detailed environmental and ecological surveys are scheduled, with focus on the ones with critical seasonality. Binnies/NOD will continue to focus on providing the relevant environmental information to support the optioneering of the scheme design. Landscape Architects have visited the site and undertaken the baseline survey with viewpoint locations identified.


Coastal & River Modelling 

Updates / June 29, 2022

Coastal & River Hydraulic Analysis is progressed with the production of updated flood maps for Dundalk, Blackrock and Ardee. Hydraulic modelling is ongoing with focus on the identification and development of the potential flood relief options.


Public Information Day - October 6th 2021 - CLOSED 

Updates / June 29, 2022

The first public consultation event was successfully undertaken despite the Covid-19 constraints.

Submissions indicate the requirement for a solution and the willingness of the members of the communities to get actively involved in the progress of the Scheme. Particularly detailed submissions have been received from a number of local residents. Follow on engagement with these residents will be of benefit as the project progresses.

A second Public Information Day will be held once an emerging preferred scheme has been identified. The specifics for this Public Information Day will be advised in due course.



Project newsletters are now available to view from the 'news' page of the website. The newsletters provides information on recent activities and other relevant information. The newsletters have been issued out to interested parties - if you want to be added to mailing list then please see the 'Website Updates & Mailing List' heading at the bottom of the home page.
