Materials for Harrisburg Projects

Base and driveway surfacing carry the work here. 3/4 minus, also called 3/4-0 or dense-graded base rock, is crushed rock graded from 3/4 inch down to fines.

It locks up under a plate and holds a drive surface.

Quarry run is raw rock straight off the pit face. Use it to build up soft ground and raise grade before a graded base goes on top.

For the drive itself, Driveway Gravel surfaces an existing drive or tops a compacted base. A minus rock compacts instead of rolling underfoot.

For garden paths, Walkway Gravel gives a finer, walkable surface that stays put.

Washed stone drains. 3/4" Crushed Stone, sold locally as 3/4 clean or 3/4 open, has the fines screened out so water moves through it.

Use it in drainage trenches, retaining wall backfill and construction entrances.

Drain rock, also called 1 1/2 clean, is washed and open. It goes in French drains, curtain drains and drywells where water needs to move instead of sitting.

Sand and soil round out a site. Washed sand beds pipe and levels under flatwork.

Mason sand suits brick and block work. Screened topsoil feeds lawns and beds, and garden soil fills raised beds where native silt is too tight to plant into.

Decorative stone finishes the yard. Natural Pea Gravel, also called 3/8 round rock, covers paths, play areas and dog runs.

Willamette River Rock and Large River Rock build dry creek beds and splash pads under downspouts. Bark dust, the local name for shredded fir and hemlock bark, goes on beds and tree rings.

Ground and Conditions in Harrisburg

This part of the Willamette Valley and Portland Basin takes 35 to 45 inches of rain a year, almost all of it between November and March. It lands on tight silt and clay that sheds water slowly.

The valley floor carries deep slackwater silt laid down by the ice-age Missoula floods. Foothill ground runs to red clay and silty clay loam.

River gravel sits along the Willamette and its tributaries.

That combination means soft, saturated subgrade through the wet months. A fines-bearing base like 3/4 minus compacts and sheds load across a wider area than a clean stone, which is why it belongs under a drive or a pad here.

Water still has to leave. Put drain rock or 3/4 clean in a trench or behind a wall and the water moves instead of pooling against the base.

Winter rain on bare silt also scours banks and cut slopes. Riprap, specified by class from Class 50 up to Class 2000, armors stream banks, culvert outlets and pond edges against that runoff.

Portland treats October 1 to April 30 as the wet weather season and requires bare ground stabilized within two days, against seven days from May 1 to September 30. Base and paving work concentrates in the dry season.

Frost heave is minor here next to winter saturation, and the frost depth figure of 12 inches is the Oregon number below about 2,500 feet, set by the county.
