Gravel, Stone and Soil for Lane County, OR
Oregon Rock Supply delivers gravel, stone and aggregate delivery in Lane County, OR, with 3/4 minus leading the list. That is the local name for crushed rock graded from 3/4 inch down to fines.
Lane County spreads across wet valley floor, coastal hills and steep mountain ground. The material you order should match the soil, water and slope under it.
Materials Delivered in Lane County
Start with 3/4 minus, also called 3/4-0 or 3/4 inch minus. It is the standard Oregon base under driveways, parking pads, shop floors and shed bases.
Oregon specifies base aggregate by top size with a minus notation. The Oregon Standard Specifications for Construction set dense-graded base at 2 1/2 inch - 0, 2 inch - 0, 1 1/2 inch - 0, 1 inch - 0 and 3/4 inch - 0 in Section 02630.10.
So 3/4 minus is a sized, dense-graded product, not a generic pile of rock.
Because it keeps its fines, 3/4 minus compacts and locks up. That is why it goes under a drive instead of on top of one.
Order 3/4 Minus for any pad that has to hold a truck.
The rest of the list splits by what the stone does: material that holds together, material that drains, and material that is there to look right.
Fill dirt raises grade and backfills before a base course goes on. Washed sand beds pipe and levels under flatwork because it drains instead of holding water.
Choosing the Right Material
Douglas County sits in Southern Oregon and spans more than one ground region, including the Klamath Mountains, the Rogue and Umpqua Valleys, and the Coast Range. That mix of mountain and valley ground is close to what Lane County carries.
Some ground calls for a compacted base, some for a drainage layer.
Lincoln County is Oregon Coast ground: basalt headlands and uplifted marine sandstone and siltstone under the hills, with dune sand and soft bluff material along the shore. That soft bluff material is the difference.
It shifts under a load, so drainage and slope protection matter more than compaction alone.
Linn County is Willamette Valley, spanning the valley and Portland Basin plus the Cascade Range. The valley floor ground is much the same as Lane County's, so material choices follow the same logic: minus rock where it needs to hold, clean rock where it needs to drain.
Ground Conditions Across Lane County
In the Willamette Valley and Portland Basin, including Eugene and Springfield, the valley floor is deep slackwater silt laid down by the ice-age Missoula floods, with red clay and silty clay loam in the foothills. That ground sheds water slowly.
The valley takes 35 to 45 inches of rain a year, almost all of it between November and March, with a seasonal high water table in the lowlands. Winter rain also runs off bare silt and scours banks along the Willamette and its tributaries.
Along the Oregon Coast and Coast Range, including Florence and Mapleton, the hills are basalt headlands and uplifted marine sandstone and siltstone, with dune sand and soft bluff material at the shore. Rainfall runs 60 to 120 inches a year, and low ground stays saturated for months.
Storm waves and surge work on beaches, dunes and sea cliffs there, and slides and slumps are a real risk in the bluffs. In the Cascade Range, around Oakridge, Westfir and Blue River, the ground is andesite and basalt with pumice, cinders and ash over it, and thin stony soil at elevation.
Snowmelt and rain-on-snow runoff scour culverts, shoulders and stream banks, and debris flows come off steep volcanic slopes. Base and paving work runs from late spring into early autumn on the coast, and the mountain season is shorter still.
Frost runs 12 inches below about 2,500 feet and 18 inches from 2,500 to 4,000 feet, with the county setting the figure. Footing depth is set by the building official, not by the material you order.

Questions About Bulk Gravel and Stone Orders
Should I order material by the ton or by the yard?
Both work, and the choice is yours at checkout. Tons are a weight and yards are a volume, so pick whichever unit you already have a number for.
Each product page has a calculator to help you size the load before you order.
Which stone is best for drainage in Lane County?
Drain rock, also called washed drain rock or 1 1/2 clean, suits French drains, curtain drains, footing drains and drywells. It is washed and open so water moves through instead of sitting.
For drainage trenches and retaining wall backfill, 3/4 clean is the angular option with the fines screened out.
What do I need to have ready for a bulk delivery?
A clear, level spot where a dump truck can reach and tip the load. The truck leaves everything in one pile, so pick a place you are happy to have the material sit.
