Ground Conditions Across Yankton County
Water drives everything here. Rain, snowmelt and spring storms hit silty loess soils that crust over and shed water instead of soaking it in.
Where that water has nowhere to go, it sits. A drive, a pad or a slab built over soft ground moves as the ground moves under it.
Across the Southeastern till plains and Big Sioux valley, shallow quartzite bedrock leaves drainage nowhere to go in places. River flooding along the Big Sioux, the Vermillion and the Missouri adds to it.
Erosion follows the same water. Gullying cuts the dissected slopes, bank scour works the river banks, and bare silt soils sheet away in spring.
The working season is the longest in the state, from the spring thaw into late fall. Wet spells break it when silt soils are too soft to compact.
Frost still goes deep. Freeze-thaw heaves drives, walks and slabs every spring.
Frost depth is 42 inches under the residential code adopted in Sioux Falls; the local building official sets the figure in other towns.
Materials Delivered in Yankton County
Base course, also called aggregate base course, 3/4 minus or crushed base, is a compacted base for drives and pads.
Section 882 Table 1 keeps subbase, gravel cushion, aggregate base course, gravel surfacing and pit run apart as separate materials. County and city specifications point back at the same sections.
Gravel Cushion is the South Dakota term for the cushion course under concrete and asphalt. It also acts as the crushed top course on a gravel drive.
Stone Screenings, called chips and dust, bed pavers and flagstone, fill joints and pack hard on walks. Driveway Gravel resurfaces an existing farm or acreage drive.
Washed Sand, or concrete sand, beds and levels under slabs and pavers. Fill Dirt, called clean fill, raises grade and backfills before base course goes down.

Choosing the Right Material
Clay County, Turner County and Hutchinson County all sit on the same Southeastern till plains and Big Sioux valley ground as Yankton County. Loess-mantled and dissected glacial till, deep silty prairie soils, sand and gravel along the river valleys, and Sioux Quartzite bedrock close to the surface.
The ground is the same, so the material reasoning is the same. Silty soils that crust and shed water still call for a compacted base and a drainage layer that moves water away.
Slopes that gully still want slope protection, and bare silt still sheets in spring. Pick by the job: base course for a compacted base, washed rock for drainage, riprap for bank work.
