The sea wall planned to run between the Douglas War Memorial and the Empress Hotel is the result of a lengthy process to identify the best possible solution.
That's the word of the Infrastructure Minister Tim Crookall, after he was asked what alternatives had been considered in Tynwald last Tuesday.
The £900,000 project is set to begin in January.
He said although there are methods of reducing the impact of the waves, these would be fruitless in the event of stormy seas:
