Simple: TDC gets the District Valuer to value the Manston site, asap.
TDC will have to get it valued if they want to CPO it (and they appear to be dead set on carrying out a CPO), and they should do it sooner rather than later – it might resolve their current predicament.
If the value seems too low to Ann Gloag, she will (probably) make that clear to TDC, who will then know they will have an expensive legal fight on their hands, and might want to have a rethink.
If the value seems too high to RiverOak, they will withdraw.
As for any commercial transaction, the price has to be right. So far, nobody has bothered to find out what the price will actually be.
If you think this is a sensible course of action, do feel free to contact TDC’s Leader and TDC’s Acting Chief Executive:
