So is the drainage work: on the flat ground around Mount Vernon, water has nowhere to go.

Materials for Mount Vernon Projects

Water that sits on flat ground has to be piped away or it finds the low spot in your yard. Washed rock is the clean drainage stone for that job, with no fines to pack tight and hold water back.

Use Washed Rock in drain tile, drywells, sump pits, downspout runs and window wells. The rock stays open, so water moves through it instead of pooling around your foundation.

From there, size up or down to fit the work.

• Riprap for culvert outlets, dam faces and spillways, sized by class.
• #4 Crushed Stone, a 1 1/2 inch clean rock, for heavy drainage and trench bottoms in wet ground.
• #57 Stone, a 1 inch washed rock, for drain tile beds and concrete aggregate.
• Stone Screenings for paver and flagstone bedding and joint filling.

Six inches of washed rock in a drain bed is a different material from base course, which is a compacted layer under a drive. Keep the two apart on the ticket.

On the dry side of the job, and South Dakota contractors order it by that name.

Gravel Cushion is the cushion course under concrete and asphalt, rolled to a stable surface. Both go down before anything else on a new build.

For drives and pads, 3/4 Quartzite is the hard pink rock quarried in the southeast corner of the state. It holds up on a drive that sees regular traffic.

Ground and Conditions in Mount Vernon

Mount Vernon sits in the James River Valley, on the James River Lowland and Lake Dakota Plain. The ground is flat glacial till over silt and clay lake bed, with deep dark prairie soils and almost no gravel at the surface.

Every load of base course, washed rock and topsoil you bring in is material the ground here does not make on its own.

There is very little fall across this ground, so snowmelt and heavy rain sit where they land. The tight silt and clay below the topsoil drains slowly.

That is the reason drainage matters more here than grade does. A downspout run or a drywell filled with washed rock gives the water somewhere to go.

Spring is the slow part of the season. The flat black soils stay soft long after the ground dries on higher country, so work waits for them, then runs through to freeze-up.

Winters bring deep frost and repeated freeze-thaw, and the spring thaw on this flat ground is slow and muddy. Frost depth is commonly 42 to 48 inches across the region, and the local building official sets the figure for your job.

Sheet flow and ditch cutting after heavy rain, gullying where field runoff crosses a drive, and wind erosion on bare flat ground in spring are the erosion problems to plan around.
