Colchester to be a World Heritage Site?

A bunch of local people known collectively as destination Colchester, working alone for the good of the town, have recently submitted a bid for Colchester to become one of UNESCO's World Heritage Sites. They have been given the full support of Colchester Borough Council, on the proviso that the council will not be asked to contribute any money towards this. In fact, the bid was completed and sent, with no costs whatsoever. Why is that? Could it be to do with the fact that it was done by volunteers; people who do this sort of thing for the love of their town; to try and make a difference where officialdom would rather do nothing in that direction? No 'consultants' were used. No fees were incurred. No parasites on the public purse. Whatever the reasons, the bid was submitted and now a waiting process has begun. It may be that Colchester doesn't stand a hope in hell of joining such a prestigious list of World locations. But why not have a go anyway? The sadness is that, no sooner has the bid been sent, the backbiting begins to try to discredit the application. A Conservative politician, (presumably jealous of other's achievements) makes a wholly unsubstantiated claim in the local newspaper that it would cost Colchester Borough Council a sum of £400,000 to become a World Heritage Site. It beggars belief! Why don't these people get behind the bid and support their town?
