Start with 3/4 minus if you are building a drive, a parking pad or a shed base. It is the standard Oregon base rock, crushed from 3/4 inch down to fines so it compacts and locks up.

Ground Conditions Across Clatsop County

Across the Oregon Coast and Coast Range, this part of the state takes 60 to 120 inches of rain a year. Most of it falls between November and March on steep slopes and low ground that stay saturated for months.

That water decides what you build with. Ground that holds water needs an open, washed stone under it so the water moves instead of sitting.

The ground itself is basalt headlands with uplifted marine sandstone and siltstone under the hills. Along the shore you get dune sand and soft bluff material, and deep weathered soil on the forested slopes.

Winter storms bring surge on the beaches and slides and slumps in the bluffs. Low ground floods in major storms, so bank and slope work takes armoring rock.

From October into April, sites stay wet and bare ground has to be covered quickly. Base, drive and paver work runs from late spring into early autumn.

The Pacific keeps winters mild, so it is months of saturation rather than frost that moves material here. A city or county building official sets any footing depth figure.

Materials Delivered in Clatsop County

3/4 minus carries the most weight here. Oregon specifies base material by top size with a minus notation, and the Oregon Standard Specifications for Construction set dense-graded base aggregate at sizes that include 3/4 inch - 0.

The same section states that base aggregate is dense-graded unless otherwise specified.

Open-graded aggregate is the clean, fines-free material, covered separately. That is the split that matters: minus under a driveway, clean in a drain.

Washed stone handles the wet side. Drain Rock and 3/4" Crushed Stone go into French drains, curtain drains and drywells where water has to move.

Rounded decorative stone has its own jobs. 3/8" Natural Pea Gravel covers paths, play areas and dog runs.

Willamette River Rock and Large River Rock suit beds, borders and dry creek beds, with the larger size for splash pads and bank work.

Sand and soil round out an order. Washed Sand beds pipe and levels under flatwork, and Fill Dirt raises grade before a base course goes on.

Delivery Across Clatsop County

You order online and a dump truck tips the load on site. Choose the material, size the quantity by the ton or by the yard, and pick a delivery date at checkout.

Have the drop spot clear and reachable before the truck arrives. The load comes off the bed in one pile, so the ground under it should be firm enough to hold it.

Oregon Rock Supply delivers across the county, including Astoria, Seaside, Warrenton, Arch Cape and Hammond. Order for one address or plan several drops on the same job.

Choosing the Right Material

Columbia County sits in the Portland Metro Area, on Willamette Valley and Portland Basin ground. That is deep slackwater silt from the ice-age Missoula floods, red clay and silty clay loam in the foothills, and river gravel along the Willamette and its tributaries.

Clatsop County ground is different: basalt headlands, marine sandstone and siltstone, dune sand, bluff material and deep weathered forest soil. Tight silt and clay holds water, so Columbia County work leans harder on a clean drainage layer under the base.

Tillamook County shares the Oregon Coast and Coast Range ground region with Clatsop County. The ground is the same, so material choices carry over in the same way.

Match the stone to the job. Minus rock compacts into a base.

Clean rock drains. Rounded stone stays loose and decorative.

Quarry run builds grade before either goes down.
