Sounds interesting, but isn't the water in the bay stagnant? People aren't allowed to swim. Having said that, this is an interesting proposal but why not try and get access to and improve Splott Beach?
The bay isnt stagnant, they pump air into it, hence all the wildlife that lives in and around it! Over the summer you couldnt stop the young men from jumping in the bay from the docks by mermaid quay. also saw some people sat in the water off the barrage as well.
After having read the full proposal, I have to say that I am very impressed. It isn't just about plonking a beach in the bay. It's about a whole new regeneration of the area. The proposals are exciting and innovative and would be another plume in Cardiff's hat.
