Residential lot dumped with rock and dirt,to make equal to street

[Thripura Vemireddy]

Hi

I am planning to buy a residential lot, which is dumped with rocks and dirt for upto 8 feet.

Now the lot is equal to road level.

will the soil support a ranch home?

what is the best foundation option for this situation? ( crawl space, slab, basement)

Are there any remedies to make the soil suitable for construction?

Planning to build a Ranch home.

I would really appreciate any inputs/thoughts.

Thanks
