Like I said previously we've already got the planning permission JUST wanted some guidance on what would anyone expect for a sensible area to leave either side of runway.
Do you mean you've got 'blanket' permission for a strip of unspecifed width.
Where do you live, surely not in UK?
Or if you've specified dimensions in your planning permission and if your dimensions differ from non- sensible (your words) answers here, are you going to re-submit your planning application.
Just curious
