The 'wider site including using for other sports like cricket etc' could also include the pitches down Cleckheaton Rd and at the side of the car park and also the Bankfoot cricket/ Bfd hockey club site below. No idea about ownership of the cricket/hockey ground though, but I assume the council own the rugby pitches. sounds like a sports village sort of thing with some kind of commercial stuff as well.
If it ever gets to the stage of proper plans being laid it could be an interesting read. Wonder if it would get 'called-in'?
