Conclusion is fairly stark for Clontarf:

”

In light of the experience gained over the New Year, consideration will be given to strengthening flood defences at a number of locations and especially along the Clontarf Road between Alfie Byrne Road and the Bull Island bridge. While the temporary flood defence measures proved effective on this occasion, it would be foolish to believe that this is a sustainable solution. At some stage either our predictions regarding the tidal height will be proved wrong or the temporary measures will be overcome by a combination of high tide, low pressure, wind speed/direction and rainfall with the result that there will be very extensive flooding in Clontarf area. A more sustainable solution is urgently required if the flooding risk at this location is to be mitigated.
