Stewart believes the best solution would be a tidal barrier at Roches Point and dismisses the quay wall option presented by the OPW and Cork City Council as “very short term”.
He also says the alternative proposals by the Save Cork City campaign group for a barrier at Little Island “wouldn’t protect all areas”.
Stewart, a respected veteran expert on environmental issues, examines the city’s flood plans in tonight’s episode of Eco Eye on RTÉ1. He then puts forward a more ambitious plan for a tidal barrier at Roches Point.
“You would have natural protection of Cork because it’s surrounded by higher ground,” he explains.
“It would at least be good to see a study done of Roches Point to see the potential of building a barrier there. There is a really good solution to be explored there.”
The OPW/City Council plan only covers the city centre and Stewart says it is practical and cost-effective, but would “do certain damage to the docklands and the quay walls” and “could prove useless” if a very large storm surge enters Cork Harbour.
