3/4 Minus, Sand and Gravel Delivery in Coos County, OR
Oregon Rock Supply handles gravel, stone and aggregate delivery in Coos County, OR. The base material here is 3/4 minus, the crushed rock graded 3/4 inch down to fines that compacts and locks up under a drive, a parking pad or a shop floor.
Across the Oregon Coast and Coast Range, the working season for base and drive work runs from late spring into early autumn. From October into April, sites stay wet and bare ground has to be covered quickly.
Materials Delivered in Coos County
3/4 minus is the standard Oregon base. It is also called 3/4-0, 3/4 inch minus or dense-graded base rock.
Oregon specifies base material by top size with a minus notation, and the Oregon Standard Specifications for Construction set dense-graded base aggregate at 3/4 inch - 0 among other sizes. Base aggregate is dense-graded unless otherwise specified.
That single size covers a lot of ground. Use it under driveways, parking pads, shop floors and shed bases, anywhere the material needs to compact and stay put.
The rest of the catalogue splits into minus material that compacts and clean material that drains.
Clean material is the other half of the pair. Drain Rock is washed and open, so water passes through instead of pooling.
3/4" Crushed Stone is the angular version, useful in drainage trenches, retaining wall backfill and construction entrances.
For smaller work, 3/8" Crushed Stone handles pipe bedding and tight drainage. 3/8" Natural Pea Gravel gives paths, play areas and dog runs a smooth rounded surface.
Decorative stone rounds out the list. Willamette River Rock and Large River Rock are water-worn stone for beds, borders and dry creek beds.
Washed Sand covers pipe bedding, leveling under flatwork and concrete mix.
Choosing the Right Material
Douglas County sits partly in Southern Oregon, spanning the Klamath Mountains and the Rogue and Umpqua Valleys as well as the Oregon Coast and Coast Range. Curry County shares the Oregon Coast and Coast Range ground that Coos County sits on, so the base and drainage choices there follow the same logic.
Where the ground differs, the material choice shifts with it. Minus material compacts into a base.
Clean material drains. Getting that pair right is the whole decision.
Ground Conditions Across Coos County
Across the Oregon Coast and Coast Range, the ground runs to basalt headlands and uplifted marine sandstone and siltstone under the hills. Dune sand and soft bluff material sit along the shore, and deep weathered soil covers the forested slopes.
Rainfall across the region runs 60 to 120 inches a year, most of it between November and March. It falls on steep slopes and low ground that stay saturated for months.
That saturation is what a thin base shows first. A base course laid too shallow over soft, wet ground pumps and rut under load, because there is nothing under it to spread the weight.
The fix is a compacted 3/4 minus base over ground that has been built up and drained. Quarry run raises grade on soft ground first.
Drain rock and 3/4 clean move water away from the base instead of letting it sit against it.
Winter storm waves and storm surge work on beaches, dunes and sea cliffs, and slides and slumps move through the bluffs. Riprap armors stream banks, culvert outlets and cut slopes against that runoff.
Frost is a minor factor here. The Pacific keeps winters mild and freezes short, so it is months of saturation rather than frost that moves material.
Any footing depth figure comes from the city or county building official.

Questions About Ordering in Coos County
Should I order material by the ton or by the yard?
Both work, and the choice comes down to how you want to size the load. Tons are a weight, yards are a volume, and the two do not convert at a fixed rate because moisture and stone size change the density.
Use the calculator on the product page to size your order, then pick whichever unit you prefer at checkout.
Which stone is best for drainage in Coos County?
Clean, open material is what moves water. Drain rock is washed and open for French drains, footing drains, drywells and downspout runs.
3/4 clean is the angular version for drainage trenches and retaining wall backfill. Both are screened free of fines, so water passes through instead of sitting against the base.
What do I need to have ready for a bulk delivery?
A clear, reachable drop spot is the main thing. The truck tips the load in one pile, so leave room for it to pull in and out and pick a spot where the pile will not block a road or a drain.
