Apologies if a thread already exists: I did search. Cork tidal flood defences are a large proposed infrastructure spend and I expected to see threads in this forum.
The long story short, Cork floods regularly. A proposal was made to build a wall around the centre part of the city. A local group object to this plan and counter-propose a tidal barrier.
Latest news as of yesterday is that the OPW are accused of overestimating the cost of a tidal barrier.Examiner Link

Interesting. It seems to me though, that the tidal barrier won't be enough on it's own, as the OPW state. It'll certainly reduce the incidence of flooding, but won't stop flooding from the river itself.
Not much experience with Cork to be honest (something I'm hoping to change now that I'm back in country), so I'm just guessing. How often has flooding hit Cork just through rainfall? I.e. Flooding that occurs during a normal tide cycle, and not flooding that occurs during an abnormally high tide.

But the criticism of flood walls is that they're up to 2 metres tall and made of concrete, it would completely reshape the nature of the city - and it's unclear whether it would even work in the case of a flood - if the retractable seating fails, the city would flood. The city needs to rely on something that they know will work. Between a tidal barrier and the dam at Iniscarra, there's more than enough capacity to prevent floors.

Two metres??? I've seen the plans and they look to be about four feet max.
