"But it's been bl**ding obvious to everyone else since the late 1940s that any additional runway(s) at Heathrow would be north of the A4."
Agreed, Dave, but IIRC the late 20th-century (
... ) proposal was for a medium-length runway which would not have needed to extend across the M25? In which case, it seemed to me that its western threshold would have been between Waterside and the M4.
Now that - for so we are told - the runway is to cross over the M25, it will need to avoid the enormous area of the M4/M25 interchange. This in turn means, presumably, that it will have to be situated further south. That, and an associated parallel-taxiway on its south side, would appear to encroach on Waterside.
Not that this project - or any other - is likely to be given the go-ahead any time soon...
