Materials for Harrington Projects

Decorative rock carries a lot of yards around here, from beds to dry creek beds to ground cover that holds a slope. What you order depends on the job in front of you.

For a driveway or parking pad

Start with 1 1/4 Minus as the structural course, then cap it with 5/8 minus. The 1 1/4 minus, sold elsewhere as CSBC, has a larger top size and fewer fines, so it carries load on soft ground.

For a long rural approach or equipment parking, Driveway Gravel is a blend quarries sell alongside the graded surfacing courses.

For beds, paths and dry creek beds

Washington River Rock is the rounded stone for dry creek beds, downspout splash pads and bed cover. Washington yards file rounded stone under round rock rather than crushed.

For swales, ditch armour, bank toes and culvert outfalls, Large River Rock is the bigger round stone that stays put when winter runoff comes through.

Natural Pea Gravel works for play areas, dog runs and planting beds. It is rounded and washed, so it will not compact and should be edged where it can wander.

For garden paths and side yards, Walkway Gravel packs down tight underfoot. Beds and tree rings take Shredded Mulch, which is listed here under its Washington trade name, beauty bark.

For drainage and hard surfaces

Drain Rock is washed with no fines, so it keeps its voids in footing drains and French drains. Stone Screenings, or crusher dust, is the minus product for paver and flagstone bedding and joint filling.

Ground and Conditions in Harrington

Across the Columbia Basin and the channeled scablands, the ground is windblown loess over basalt. Where the Ice Age floods ran, that silt was stripped off and the rock left bare, and the floods dropped sand and gravel bars behind them.

Where the loess still sits, it is deep, dry and loose. Rain here is scarce, and when a thunderstorm or rapid thaw does land, silt sheds water instead of soaking it up.

An under-built base on ground like that moves.

Wind off bare silt cuts rills and gullies, and short violent runoff does the same. That is why the structural course under a driveway or pad matters more than the surface stone you see.

Eastern Washington's wet weather season for erosion control runs October 1 through June 30. Once snow falls or the ground freezes, placing and compacting base material stops being practical, so plan the granular work around that.
