Dublin city councillors have voted to spend half a million euro on lowering the new sea wall in Clontarf.
That's despite the city manager warning it won't meet national flood protection standards.
This long running row centres on a partially built wall measuring around 500-600 metres near St Anne's Park.
Works to lower it are to be carried out after Clontarf locals mounted a massive opposition campaign, claiming it blocked their views of Dublin Bay.
Last night councillors voted by 34 to 21, in favour of spending €500m euro on reducing the height and resurfacing the barrier.
The city manager has warned money will have to be spent on raising it some time in the future, because these works will mean the wall doesn't offer the national standard of flood protection.
A number of reps slammed the decision after the ballot.
Labour's Rebecca Moynihan said it was bizarre and irresponsible to reduce the wall for the benefits of drivers who should be looking at the road and not the sea.
