I really cant see this as a quick fix it could take years yet.
Here is a thought for you.
Planning permission for a 15k stadium with associated add ons, like say 100 student accommodation units. That means the property company could be taking in rents from CCFC, CRFC and rents from 100 students.. Could easily add up to 750k pa annual rents receivable if not more. Now that may come back to CCFC or CRFC but there will be finance to meet on the build first. What it does do however is to create a rental capital value. Something to sell on - and I am not necessarily saying sells the club. Thing is maximising the student accommodation or other such apparently attractive things could end up failing to maximise the benefit for CCFC/CRFC.
The rugby club doesn't actually need a big stadium and we would then be stuck there
Got a feeling this plan has another side and objective to it away from CCFC. Just guess work and an opinion I have absolutely no proof
