deep fill for driveway ramp

[Hotzcatz]

I think the general method to build up an area like this would be to do it in layers of rock - possibly 3/4" minus? - with a lot of compaction between layers. Also adding in some drainage to keep it from being undercut if there's a waterpath through it. But for eight feet of elevation change, that's huge. Got any engineer friends to ask?

Another option would be to sell that lot and buy one without the same complication.
