3/4 Clean, Stone and Soil Delivery in Otis Orchards, WA

Washington Rock Supply handles gravel and aggregate delivery in Otis Orchards, WA, by the ton. The Washington default surfacing course is 5/8 minus, also called crushed surfacing top course or CSTC.

It is crushed rock with the fines left in, so it packs hard and sheds water instead of soaking it up.

Underneath, the Spokane Valley ground is cobbles, gravel and sand left by the Ice Age floods. That open ground shapes how a yard here drains, and it shapes what you put on top of it.

Materials for Otis Orchards Projects

Washed stone does the drainage work on a lot in this valley. Because the fines are taken out, the stone keeps its voids and water passes through instead of sitting against a foundation or a footing.

For footing drains, French drains, curtain drains and infiltration trenches, use drain rock, also called 7/8 clean or washed rock. It is washed and fines-free, which is what you want where a perched water table sits on till.

For downspout runs and under-slab drainage, 3/4 clean is the washed counterpart to a minus product. It drains instead of compacting, which suits trench backfill and pipe surround.

Drywells take a larger open stone.

Pair it with #4 Crushed Stone for heavy drainage, or step down to #57 Stone for trench backfill and concrete aggregate.

Where a drive or a parking pad needs a surface that holds together, the minus products take over. 5/8 Minus is the top course.

1 1/4 Minus, also called crushed surfacing base course or CSBC, sits below it as the structural course, with a larger top size and fewer fines so it carries load on soft wet ground.

Ground and Conditions in Otis Orchards

Across the Spokane and the Selkirk foothills, the ground drains almost too well. The valley gravel is open enough that water moves through the aquifer below it quickly, which makes infiltration easy.

It also means whatever is on the surface goes down with it.

That is the case for washed stone on drainage work and for keeping a site covered. Compacted fill and shallow basalt shelves are where the wet spots show up instead.

Timing matters as much as material. There is a long dry season for base and paving work, then a hard stop once the ground freezes.

Erosion control in this part of the state runs October 1 through June 30.

Winter brings repeated freeze-thaw on unbound surfaces, and Spokane sets its footing depth well below the western Washington figure for that reason. The frost line depth in the Spokane Municipal Code design criteria is 24 inches.
