3/4 minus is the base that compacts and locks up under a drive, a shop floor or a shed pad. Across the Columbia River Gorge and Plateau the ground is loess over basalt, so what you put on top matters.

Materials for Grass Valley Projects

Water is the thing to plan around here. Loess sheds rain fast when dry, turns greasy when wet, and sends winter runoff off frozen ground in a hurry.

Washed stone gives that water somewhere to go instead of letting it sit against a footing or pool at the low corner of a pad.

Drain rock, also called 1 1/2 clean, is washed and open so water moves through it rather than sitting in it. It goes in French drains, curtain drains, footing drains, drywells and downspout runs.

3/4" Crushed Stone, or 3/4 clean, is angular rock with the fines screened out. Use it in drainage trenches, behind a retaining wall, on a construction entrance, or to bridge soft wet ground.

3/8" Crushed Stone is the small angular size for pipe bedding and tight drainage work. A thin layer over a compacted base also gives you a finer surface.

Where a drive or pad needs to hold up, 3/4 Minus is the standard Oregon base: crushed rock graded 3/4 inch down to fines. Quarry Run is raw rock straight from the pit face, uncrushed, for building up soft ground and raising grade before a graded base goes on.

For a walkable path, Walkway Gravel gives you a finer surface that stays put underfoot. 3/8" Natural Pea Gravel is the rounded option for paths, play areas and dog runs.

Beds and borders take Willamette River Rock, water-worn stone off the valley river bars. Large River Rock suits dry creek beds and splash pads under downspouts, where small stone would wash out.

Ground and Conditions in Grass Valley

This part of the state gets 8 to 15 inches of precipitation a year, so volume is not the problem. The problem is ground that turns greasy when wet and sheds water when dry, then runs off hard in winter.

Wind moves bare loess, cultivated slopes cut into rills and gullies, and summer thunderstorms send sudden runoff down dry draws. That shapes where you put washed stone and how you finish a slope.

The working season runs long, bounded by hard frost at one end and summer dust at the other. Water for compaction usually has to be hauled out onto the plateau, so plan that into your timing.

Winters here are cold and dry with a hard east wind through the Gorge, and ground frost goes deeper than it does west of the Cascades. Confirm the footing depth figure with the Sherman County building department.
