Frequently Asked Questions

Q: How has the scheme been funded?

A: The OPW is providing funding for the initial phases of the project (feasibility and initial design) and will also fund construction works when planning permission has been granted.


Q: What is the purpose of the scheme?

A: The scheme will improve the standard of flood protection for Carrickmines Shanganagh to protect against the 1 in 100 year fluvial (river) flood.


Q: Is there anything planned for other parts of Dún Laoghaire Rathdown County?

A: The OPW commissioned a series of Catchment Flood Risk Assessment and Management Studies, including the Eastern CFRAM. Dún Laoghaire Rathdown County Council are also progressing a Flood Relief Scheme for the Deansgrange stream through a separate project and brief.

In addition to the Deansgrange and Carrickmines / Shanganagh / Loughlinstown schemes, the Eastern CFRAM Study resulted in the publication of a Flood Risk Assessment and Management Plan (FRMP) which outlined flood management measures for other towns.  More information on the CFRAM Studies can be found on the project website .


Q: Will the scheme increase the risk of flooding in other places?

A: No, this will be a key consideration in our design. We will consider the impacts on the Carrickmines Shanganagh River catchment as a whole, rather than focusing on the places that are predicted to flood, to ensure that any works completed as part of this a scheme do not increase the flood risk to surrounding lands.


Q: Am I at risk of flooding?

A: You can look at the flood maps on the OPW’s CFRAM website to see the flood extents for Deansgrange and other towns within the CFRAM study area .


Q: Who can help?
