It was always a potty idea proposing to build a new hospital on a flood plain which is feet deep in water every few years.
Even if it had been built on stilts at great expense, the associated car parking would have had to have been built on stilts as well or the tarmac would have sealed the ground in and so back to square one.
Why go to all that trouble, and increase the periodic flooding of the surrounding properties, when you can just build the thing on dry land in the first place?
