What Jerauld County's reading doesn't cover

Two lots a mile apart in Jerauld County can carry different soil, even though they share one countywide reading. A site-specific soil report, usually $1,000-$5,000, is what an engineer would actually pull before designing a foundation on a lot in Jerauld County.
