So it looks like a race between them and ASDA?????
Seriously though, I have been following this as a Marina Berth Holder Representative for some time and the plans are brilliant as shown.
I can see the lock and cut from the Wellington to the Marina, and the Marina itself and its surroundings, developing into a smaller version of Brighton Marina or St Katherine's London with all sorts of retail attractions. This would certainly draw the punters into Dover (unlike than the chance to save a couple of pence on ASDA baked beans).
At that point here should be enough momentum post recession to develop the DTIZ into upmarket flats, especially if we can retain the fast rail-link to London.
It makes so much sense that I suspect it will only be a matter of hours before some prat from Fort Whitfield starts opposing it!
