Materials for Elmira Projects

Water is the whole job in this part of the valley. Winter rain lands on tight silt and clay that sheds it slowly, so drains, drywells and downspout runs have to move it away instead of holding it.

Washed stone is screened free of fines, which leaves open voids for water to pass through. That is the opposite of a minus rock, which keeps its fines and compacts into a base.

Drainage stone

Drain Rock, also called 1 1/2 clean, is washed and open for French drains, curtain drains, footing drains and drywells. Water moves through it rather than sitting against your footing.

3/4" Crushed Stone is angular rock with the fines screened out. Use it in drainage trenches, retaining wall backfill and downspout runs.

3/8" Crushed Stone is the small clean size for pipe bedding and tight drainage work where a larger stone will not fit.

Base and surfacing

3/4 Minus, also called 3/4-0 or dense-graded base rock, is the standard Oregon base under driveways, parking pads, shop floors and shed bases. It is graded 3/4 inch down to fines so it compacts and locks up.

1/4 Minus, or quarter minus, beds pavers and flagstone and tops a compacted base. It also fine-grades paths.

Driveway Gravel surfaces an existing drive or tops a compacted base. On most Oregon drives that means a minus rock that compacts rather than a clean rock that rolls underfoot.

Decorative and soil

3/8" Natural Pea Gravel is rounded stone for paths, play areas and dog runs. Willamette River Rock is water-worn stone for decorative beds and dry creek beds.

Top Soil is screened for lawns and finish grading, and Garden Soil fills raised beds where the native ground is too tight to plant into.

Ground and Conditions in Elmira

Plan around the working season. This part of Oregon takes 35 to 45 inches of rain a year, almost all of it between November and March, and bare ground has to be stabilized within two days from October 1 to April 30.

That leaves the dry months for base and paving work. Across the Willamette Valley and Portland Basin the ground is deep silt on the valley floor and silty clay loam in the foothills, and it stays soft through the wet season.

Frost is a minor problem here next to saturation. The county sets a 12 inch frost depth for footings, which is the Oregon figure below about 2,500 feet.

For drainage, the open stone does the work. For a drive or a pad, 3/4 minus compacts into a surface that holds up under a truck.
