New images of potential Cork tidal barrier released 

Save Cork City has released new images of a potential tidal barrier for Cork.

The new images show the tidal barrier in Lough Mahon as a civic amenity, with green spaces, walkways and water access depicted. 

However, it is unclear whether Cork will ever see a tidal barrier.

For over a year now, there has been a dispute over which of Cork's two flood defence proposals would be more effective.

The two plans have been put forward by Save Cork City, and The Office of Public Works (OPW) and Cork City Council. 

The Save Cork City campaign argues that a tidal barrier is the best way for Cork city to defend itself against flooding.

They are opposed to the OPW and Cork City Council's Lower Lee Flood Relief Scheme, which they say is a "walls scheme".

The campaign believes that a tidal barrier in Lough Mahon, combined with the repair of Cork's historic quay walls and using the existing infrastructure of the upstream Dams, can protect Cork from flooding.

Save Cork City claim that "management of the entire River Lee catchment could include water storage and reuse of flood plains, tree planting, wetland restoration, water diversion, attenuation, reinstatement of ditches and alteration of land drainage methods in cooperation with landowners who may have a vital role to play."

Save Cork City are opposed to the Lower Lee Flood Relief Scheme (LLFRS) due to their belief that it will impact the aesthetic of Cork's historic quays.

They also claim the construction of quay-side flood defences will be "disruptive" for the city. 

LLFRS involves constructing flood defences along Cork's quays. The OPW claims that their scheme, running from Inniscarra Dam to the City Centre, will protect over 2,100 properties, including 900 homes and 1200 businesses, against tidal and river flooding.

"The scheme will enhance connectivity to the river by providing almost 1km of new river walkways and invest €20m in the repair of historic quay walls. 

"Over 390 Protected Structures will be protected by the scheme and improved public realm spaces will be developed across the city, for example in Morrison’s Island."

Cork City Council and the OPW have continually defended their plan, saying it is the best way to protect Cork from flooding.

Ken Leahy of the Lower Lee Flood Relief project consultants ARUP, previously dismissed claims that their €140 million flood defence system, based on containment and pumping, will not work.

Mr Leahy conceded that a tidal barrier would solve the issue of tidal flooding, but said it would not protect Cork from fluvial [rainfall] flooding. The OPW claims fluvial flooding accounts for almost three-quarters of flood events across Cork city.

Mr Leahy also claimed the barrier would cost millions of euros per year to operate.

Save Cork City and the OPW and Cork City Council are at odds with each other over the costs of both their projects, the measurements of quay wall heights, groundwater mitigation, the effectiveness of a tidal barrier, the causes behind flooding in Cork and the effects of climate change on both of the potential projects.

Both sides have been actively campaigning on social media, arguing that their scheme is the solution to Cork's flooding problem.

LLFRS must receive approval from the Minister of Finance, Paschal Donohoe, before construction can begin.
