Base course is the crushed layer that carries a drive, a parking pad or a shop slab, and it is the name South Dakota contractors order by.
Hand County sits on the Missouri Coteau, a jumble of knobs and closed kettles in stony glacial till over Pierre shale. Gravel shows up in the kames, and much of the county has no natural drainage network at all.

One truck, one pile. Plan where you want the pile to sit before the truck arrives, because the driver tips the load and leaves it there.
Materials delivered in Hand County
Lead with the project. A driveway, a patio, a drain and a garden bed each call for a different material, and the local name is what gets the right truck to your place.
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 rolled out under concrete and asphalt and the crushed top course on gravel drives. It is a different material from gravel surfacing under Section 882, so order it by the name gravel cushion.
For drainage, washed rock handles drain tile, drywells and downspout runs. Natural Pea Gravel covers paths, play areas and dog runs where a rounded, walkable stone is wanted.
Stone screenings bed pavers and flagstone and pack hard on a walk.
Ground conditions across Hand County
Across the Missouri Coteau, the ground is hummocky stagnation moraine: knobs and closed kettles in stony glacial till lying over Pierre shale. Gravel sits in the kames, and much of the county has no natural drainage network.
Water has nowhere to run here. The kettles and sloughs are closed basins, and the shale under the till stops what does soak through, so low ground stays saturated.
A driveway or pad that goes in over saturated ground will not hold up.
Wind scour works the open knobs, runoff cuts the steeper coteau slopes, and wave action works the reservoir shorelines. Riprap and large river rock protect those edges where water and wind pull at them.
Winters here are long, cold and windy, with deep frost, heavy drifting and hard freeze-thaw cycling on exposed ground. The working season is short between the spring thaw and freeze-up, and wind and drifting stay a factor well into spring and again from late fall.
Frost depth in this part of South Dakota is commonly 42 to 48 inches. There is no statewide figure, and the local building official sets the depth that applies to your job.
Choosing the right material
Hand County sits on the Missouri Coteau, and so does Faulk County. The ground there is the same hummocky stagnation moraine over Pierre shale, so the base and drainage reasoning carries over.
Beadle County and Spink County sit in the James River Valley, on the James River Lowland and Lake Dakota Plain. That ground is flat to gently rolling glacial till over the silt and clay floor of glacial Lake Dakota, with deep dark prairie soils and very little natural relief.
That is a real difference. Lake Dakota Plain ground has little gravel at the surface, while Hand County has gravel in the kames.
Where the surface has no gravel, a base course has to be brought in rather than pulled from the ground underfoot.
The flat ground also changes drainage. Hand County sheds water poorly because the kettles are closed basins, and level ground with heavy silt and clay soils holds water too.
Either way, a clean open stone like washed rock is what moves water away from a base.
Match the material to the job. Base course for a drive, a pad or a slab.
Gravel cushion under concrete and asphalt. Washed rock for drain tile and drywells.
Riprap for culvert outlets and dam faces. Topsoil and garden soil for growing ground, and fill dirt for raising grade before a base goes down.
