In a perfect world, given unlimited funds, the area within [pick your own distance] of the RW would be level and unobstructed. How far would you extend? How much of Madrid would you level in the process [or indeed the Bath Road adjacent to Heathrow]?
I do understand all of that - necessary compromises. But, as if the gully wasn't enough, would you operate a quarry between runways as Madrid appears to be doing? That does strike me as a little .......... er, deranged.
(Unless, of course, they're filling it in.
