The tidal barrier protects more of Cork for less

The Tidal Barrier protects Docklands, Tivoli, Blackrock and Douglas and supports free movement for navigation. It is the preferred choice of environmentalists and those who wish to protect tourism and the local economy.

The tidal barrier represents good governance, saves money, creates business opportunity and doesn’t create traffic. It gives flood protection in less than half the time and facilitates better consideration of transport and infrastructure. It allows us to move forward as a city with confidence with full regard for the wellbeing of citizens. The Tidal Barrier is part of a combined system working with the Dam to support safer and more future resilient flood protection for the city.

Flood Walls in Cork described as “a serious risk to life” by HR Wallingford

The Walls proposal places quaysides below designed flood levels for the first time in history. With 46 pump chambers and almost a kilometre of demountable barriers, the Walls are susceptible to catastrophic failure, a huge maintenance burden for Cork and a loss of distinctive character for the city.

Dublin has rejected future Walls and is planning for a Tidal Barrier

Dublin rejects walls as they can’t be raised indefinitely.

Cork is more suited to a Tidal Barrier.

The HR Wallingford Tidal Barrier Report

“..the tidal barrier scheme “has the major benefit of not requiring the construction of walls along the quays in the city.” HR Wallingford World Leaders in Hydrology

The tidal barrier proposal “would also avoid the scenario of overtopping or failure of flood walls in the city which would cause serious risk to life as well as damage to the city.” - HR Wallingford

“In my opinion, the alternative solution for flood protection for Cork is viable and would have the major benefit of minimum disruption to the city. A tidal barrier is an effective means for preventing tidal flooding and providing storage for fluvial flooding which could work in combination with dam management to protect the city. In addition, natural flood management can help to reduce the speed by which rainwater becomes flood water over time and represents good long-term policy. It has been demonstrated that fluvial floods can be controlled using the existing hydropower reservoirs.David Ramsbottom HR Wallingford
 

The EU Floods Directive 2007

(Best Practice in Flood Relief)

“With a view to giving rivers more space, they should consider where possible the maintenance and/or restoration of floodplains, as well as measures to prevent and reduce damage to human health, the environment, cultural heritage and economic activity.

an assessment of the potential adverse consequences of future floods for human health, the environment, cultural heritage and economic activity.......including floodplains as natural retention areas, the effectiveness of existing man-made flood defence infrastructures (our Dams), the position of populated areas (our City), areas of economic activity (our City) and long-term developments including impacts of climate change on the occurrence of floods.”

What the World Bank Says:

“A city’s conserved historic core can differentiate that city from competing locations, branding it nationally and internationally, thus helping the city to attract investment and talented people.”

“Heritage anchors people to their roots, builds self-esteem and restores dignity”
