Proposed flood defences at Clontarf in Dublin will not now go ahead after city councillors voted unanimously against the plan.
Local resident and business groups in Clontarf had vigorously opposed the works consisting mainly of grass mounds along the 3km promenade.
The mounds would have been up to 2.17 metres (7"2") in height and also included some walls beside car parks.
Local people were concerned about the loss of sea view and had security fears because the promenade would be obscured from the road.
City officials offered to reduce the height and stated that in the final plan 83% of the defences would be under 1.5m - a height that would not obscure the view from the road.
But this evening's monthly meeting of the city council heard that local residents remain opposed to the plan.
Local councillor Gerry Breen said councillors reflect what the public want and said "the public doesn't want this".
Cllr Jane Horgan Jones said the responsibility for this "mess" lay with council officials for the deficiency of their original consultation.
City Manager John Tierney confirmed that the works will not now go ahead in their present form.
He said officials will now consult again with local interests but added he would not underestimate the difficulty of finding agreement on the balance between defence and amenity.
Mr Tierney has stated that the funding of €4.3m from central government for the works would now be suspended if the plan was not agreed by the end of this month.
He said tenders will be sought for a water mains project on the seafront that was originally planned to be built along with the flood defences.
