Castletown Harbour Tidal Walls

The £2.3 million project is part of the Government’s overall strategy to mitigate the impact of rising sea levels and severe weather as a result of climate change.

The project is the first phase of an All-Island plan of Climate Change Adaptation and will deliver a scheme to reduce the risk of tidal flooding during high tide events in Castletown Harbour. 

The Castletown scheme, which commenced on Monday 8 May, involves the installation of raised or set-back harbour walls.
