deep fill for driveway ramp

[dobanion]

I'd wonder, being way down in a puka (sounds like), you scoped out what it's like there after say 3 days of heavy rain? Be sure the lot isn't like that movie, A River Runs Though It.

Is the paved road artificially built up?

CCat, sounds like you should just invite all of us out there for an afternoon and we can look at your lot and argue for *hours* about what to do with it, if you should keep it at all, how the Shipmans stole all your soil and took it to Keaau, why the subdivision is illegal, etc etc...

Haha ramdomq, we would do that wouldn't we?

I should have kept my thoughts down to "go to Puna Rock," would have been simpler.

Oh hey, I wasn't trying to discourage any speculation! More suggesting that we would all have good fun! :-)

Is the paved road artificially built up?

yes, exactly.

How long have you had this property? Not knowing where it is located, but there are good reasons why the roads and highways are built up in many areas. There are many stretches of Hwy 11 that are higher than adjacent properties. Some flood quite severely.

Do you think it might have water flow parallel to the roadway that may also require a culvert? Sounds like you will need a very good base to build on and a lot of rock. It won't be cheap or easy.

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.

This post started September 2023 so I wonder if anything has been done re driveway buildup.
My experience is that "free" rock or dirt is very available but it never costs less then $200 to get it delivered and that was over a decade ago.
Add to that the fact of "free" dirt usually has the absolute largest content of weeds or even worse growing things inherent in it.
