Riprap, Stone and Soil Delivery in Alsea, OR

Oregon Rock Supply brings gravel and aggregate delivery in Alsea, OR, and winter water is the reason most of it gets ordered. Rain lands on tight silt and clay across the Willamette Valley and Portland Basin and sheds slowly.

Coarse stone carries that water. Riprap and clean rock hold banks and swales, while 3/4 minus builds the compacted base under a drive or pad.

Materials for Alsea Projects

Start with the big stone. Riprap armors stream banks, culvert outlets, pond edges and cut slopes against winter runoff, and Oregon specifies it by class from Class 50 up to Class 2000.

See RipRap.

Below that, 3/4" Crushed Stone is angular rock with the fines screened out. It goes into drainage trenches, retaining wall backfill and construction entrances, and it bridges soft wet ground.

Where water has to move rather than be held back, Drain Rock is washed and open. It suits French drains, curtain drains, footing drains, drywells and downspout runs.

For the ground itself, 3/4 Minus is the standard Oregon base under driveways, parking pads, shop floors and shed bases. It is crushed rock graded 3/4 inch down to fines, so it compacts and locks up.

Finer work takes finer stone. 1/4 Minus beds pavers and flagstone, tops a compacted base and does fine grading on paths.

Washed Sand beds pipe and levels under slabs, and it drains instead of holding water.

Ground and Conditions in Alsea

Across the Willamette Valley and Portland Basin, 35 to 45 inches of rain falls almost entirely between November and March. It lands on tight silt and clay that sheds water slowly, and the lowlands carry a seasonal high water table.

That combination drives the material choice. Water sits instead of soaking away, so drainage stone and coarse rock do the work that soil cannot.

Winter rain also runs off bare silt, scours banks on the Willamette and its tributaries, and triggers slides on steep foothill slopes. Riprap and clean stone answer that directly.

Timing matters as much as stone. 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.

Winters here are mild and wet, with only short freezes. Frost heave is a minor problem next to winter saturation and soft subgrade, so the base is usually the first thing to sort out.
