There are certain aspects of the promotional video which give rise to concern, I believe. The omission of the fishtails in the first phase is almost certainly a mistake; more worryingly, it reveals the mindset behind the project is focussed on spending as little as possible.
The commentator refers several times to 'increased risk of major storms' and then the video shows damage, most of which occurred in the 1991 storm. He also states 'Global warming will lead to an increased risk of major storms hitting the Bay of Colwyn' but the jury's still out on the long term effects of climate change, the term he ought to have used, other than the certainty that increased sea levels will be involved.
My main concern is that the project doesn't get done on the cheap. As Mike says, the plan is excellent, and we can only hope that penny pinching doesn't ruin what could be an outstanding development for Colwyn Bay.
