PROPOSAL FOR A PROMENADE FROM MERRION GATES TO DUN LAOGHAIR

April 1, 2026

EAST COAST RAILWAY INFRASTRUCTURE PROTECTION PROJECTS – MERRION TO DUN LAOUGHAIRE SECTION


  • A project is in progress by Irish Rail to provide improved coastal protection against predicted climate change effects of sea level rises and coastal erosion on the east coast railway corridor between Merrion Gates and Wicklow Harbour.
  • SAMRA attended an initial Public Consultation on this project at the Royal Marine Hotel, Dun Laoghaire on 12th November 2024, with a particular interest in the section of the route from Merrion Gates to Dun Laoghaire.
  • Along this route there are various design proposals to protect the rail line from  flooding. One such proposal is the extension of the existing rock embankment, a so called rock armour outside the rail line.
  • Following review of these proposals, including a discussion with the Design Consultants, Jacob Engineering, SAMRA made a Submission to the Consultation suggesting that a walk and cycle way be incorporated into the scheme.



THE SUTTON TO SANDYCOVE CYCLE AND WALK WAY PROMENADE -S2S


  • Michael Collins, retired Architect from his own well known firm, instigated the S2S concept for a cycle lane along the Bay from Sutton to Sandycove back in the 1990s, and it then became Government policy. 
  • The arc on the northside from Clontarf to Sutton is in place and Dublin Port are in the process of extending it through the Port to the Liffey. 
  • Their 3fm project to develop the south side of the Port is currently at Planning stage and allows for a cycle lane across the river as part of a new bridge that is proposed as part of the project. They then plan to extend it to the Sandymount seafront along the east side of the Glass Bottle site. 
  • SAMRA and the bulk of the Sandymount Community are advocating for the proposed cycle way along Strand Rd to be incorporated into the Sandymount enhanced flood defences project currently also being designed by Jacobs Engineering.
  • As such, the addition of a cycle and walk way along the rail line as part of the Irish Rail flood defences project would then extend the S2S promenade to Dun Laoghaire, which along with the existing cycle and walk way to Sandycove, would complete the full S2S. 
  • In parallel with SAMRA's Submission to the initial Public Consultation on the rail line project, Michael Collins provided a well developed scheme for such a promenade, and made a Submission accordingly. Such a promenade could also accommodate Eirgrid's proposed installation of 225 KVa cable from Carrickmines to Poolbeg.
  • An S2S Group is now lobbying for his scheme making a strong case including that a three agency combined project not only makes huge sense, but is entirely in line with the recently published Accelerating Infrastructure Policy which calls for various State agencies to work with each other on local projects and seeks to encourage public buy in. Such buy in would be significantly supported by the community gain that the rail line project would provide by including a coastline promenade in its scope.



DUBLIN BAY, A DESIGNATED UNESCO BIOSPHERE 


  • Dublin Bay is an ecosystem that is home to many rare and important species of wildlife.
  • In 2015 the Bay as a whole was designated a UNESCO Biosphere, and is the only capital city in the world with such a Biosphere on its doorstep.
  • The designation reflects its significant environmental, economic, cultural and tourism importance, and is recognised as such by Dublin City Council.
  • Bird wildlife includes Brent Geese, who winter there, and the Oystercatcher.
  • Fish life includes the Harbour Seal and the Grey Seal. 
  • Empty Cockle shells are a very common feature in the beaches, and a pioneer plant is the Common Cordgrass.
  • 32 species of green seaweeds have been recorded on the Bay mudflats. 
  • The rocky shorelines provide habitats for plants and animal communities.
  • As described by the Irish Conservation a Wild Birds Regulations, the inter-tidal land portion of the South Bay is an area of 7.25 square kilometres. As such, it is larger than the Phoenix Park, the biggest enclosed park in Europe.
  • This inter-tidal walkable portion of the Bay provides an incredible sand landscape with a vast horizon, a destination, a waterpark, an environmental sanctuary.


As such Dublin Bay is a free gift of Nature and a wonderful amenity for its citizens and visiting tourists.



SAMRA'S SUPPORT FOR PROMENADE PROPOSAL


  • SAMRA fully and enthusiastically supports the S2S Group's call for a promenade with a cycle way extending our promenade from Merrion Gates all the way along the shoreline to Dun Laoghaire. We are joined in that support by the community groups of Booterstown and Trimleston, and are united with the communities of Blackrock, Monkstown and Dun Laoghaire in calling for such a promenade to be incorporated into the proposed Merrion Gates to Dun Laoghaire rail line enhanced flood defences project.
  • We believe that the proposal presents a once in the lifetime opportunity to provide such a facility.
  • What a fantastic amenity it would provide for Dublin and its tourist industry. 
  • It would hugely enhance the vistas and experience of Dublin Bay from the south side, which are currently relatively restricted to Sandymount and the Dun Laoghaire to Sandycove area.
  • The gift of Nature that is the UNESCO Biosphere, as described above, would be dramatically displayed to citizens and tourists alike.
  • The shoreline links to the villages of Blackrock and Monkstown, with their many attractions, would be opened up, access would be provided to many historic features along the coast, and it would provide a wonderful panoramic route for active travel for visitors all the way from Dun Laoghaire to Dublin City.

Fast facts  Raw Sewage outflow occurs across from St Albans/Strand Road 10-12x per year Discharge pumps respond to high water level to avoid flooding at St Albans residential area Raw Sewage released is unfiltered with condoms and sanitary products left deposited on the beach amongst faeces Creates an immediate Public Health Hazard to Dublin Bay Sandymount & Merrion Beach Sandymount & Merrion Beach is used by 100s of walkers, pedestrians per day There is no/inadequate public signage of the hazard There is no clean-up operation triggered by DCC or Irish Water It can take + 2 weeks to clean up after each event Correspondence has been formally exchanged with DCC CEO on incidents dating back to 03/06/2022 c/w photographic evidence of the extent of beach erosion and evidence of health hazard and lack of clean-up A complaint to EPA was formally filed 03/11 2022 with all back-up and Irish Water formally closed out the complaint 16/11/2022 The event of 11/05/2023 carries video evidence of the flow and the aftermath on the beach, widely reported on the media Irish Water are responsible for this system BUT carry no responsibility for Clean Up DCC do not accept responsibility for clean-up below the High Water line and will only clean-up on a limited discretionary requested basis on the Strand There is clear acceptance by our agencies of Dublin City Council and Irish Water of the creation of a Public Health Hazard with no effort made to provide signage or clean-up services It is asserted that Ireland’s agencies including the EPA have become normalised to the acceptance of this status on Ireland’s capital city beach – and are prepared to leave the public at risk to this hazard Notes from meeting with Uisce Eireann, Deputy James Geoghegan TD and SAMRA , 4 TH February 2026 Attendees Deputy James Geoghegan TD SAMRA: David Turner - Chair Karl Anderson - Strategic Communications and Media UISCE EIREANN Steve Seymour – Head of Asset Management Ted O’Reilly – Asset Planning Senior Manager Michael Goss – Wastewater Network Manager AGENDA 1. Extent of Current BioHazard · Number of people, children and pets exposure on the city beach · Raw sewage to beach, media : video, pictures (as per SAMRA website) · Dublin Bay (UNESCO Biosphere and the only associated with a capital city) a previous Blue Flag beach - now the 2nd worst performing in the state 2. What is the Plan to STOP the pollution at St Albans outfall ? Opportunity : Inclusion into the promenade flood alleviation scope 3. Immediately Available Actions to Uisce Éireann Signage Clean-up 4. As the Accountable Agency - WHAT IS Uisce Éireann's Commitment Project Timeline 3 decades on MEETING KEY POINTS James Geoghegan invited SAMRA to overview the context of why we’re here after his challenge to Uisce Eireaann (UE) Sean Laffey in the Dail PAC on 6th November SAMRA overviewed key context points commenting on UE opening slide of a St Albans flooding. The correct priority is in place to pump to the beach rather than flood residential home HOWEVER, the city UNESCO beach has become a toxic place and people, children, dogs are routinely getting sick AND this has been going on for 3 decades - what is UE plan ? UE spent 45 minutes explaining from an engineering perspective, why this a legacy issue and a very complex problem to resolve: development of the hydraulic model drainage area plan (DAP) needed to inform feasibility assessments and decisions: 2 years; due to be complete in 2026 for St Albans area For a 1:5 year storm, containment of St Albans upstream drainage area 45,000 people = 17,000m3 tank (9 Olympic swimming pools) and no identifiable storage site However, to set expectations there are 40-50 DAPs in progress across Ireland Also, to get through to a Capital Funded Plan - minimum 7-10 years (and probably more given the reference of the Blanchardstown plan which took 5 years on a greenfield site outside the complexity of Dublin) UE overviewed what they have/are doing with respect to St Albans: weir to reduce backflow improved pump system at Aylesbury improved telemetry for pump activation annunciation pump performance monitoring to avoid breakdowns DCC beach clean-up service to UE at present and staff will transfer to UE by the end of 2026 - increasing transparency UE response Priorities : response < 4hours for internal flooding to certain premises response < 12 hours for flooding to gardens & streets, etc UE confirmed that the above are all incremental and in reality we have minimum 7-10 years to wait with current status quo, to get to a solution - where residents meanwhile have to cope with toxic conditions We asked questions and discussed : possibility of running an extension pipe across the beach to eliminate the risk whilst engineering is underway in parallel - UE - planning permissions/delays incorporation of a local break tank: volume needed too high and space restrictions incorporation of a line into the upcoming flood defence works - will be explored with OPW and Jacobs exertion of external fines from EU - as with Cork impending, not clear this will make a difference exertion of political pressure - unclear In view of the above, we asked UE to consider how to minimise risk to people whilst the engineering is developed: Communication - there is currently NONE Signage - what is in place is INADEQUATE Clean-up - there is currently LITTLE OR NONE SUMMARY UE presented the complexity of the problem that they have inherited and are working through from an engineering perspective UE did not present any options of what they can do to mitigate risk to people UE did not make any commitments or present any mitigation plan at this meeting BUT they undertook to now consider mitigation options David Turner Chair SAMRA
