5/8 minus is the state's default surfacing course.
Contractors shorten that to CSTC and order it as 5/8 minus.
Use it for driveways, parking pads, shed slabs and shop slabs. It is the course that takes the traffic and the weather.
Below it sits 1 1/4 minus, the crushed surfacing base course, or CSBC. Larger top size, fewer fines, so it carries load and stays workable on soft wet ground.
Washed stone handles the water. Drain rock, also called 7/8 clean, keeps its voids where a perched water table sits on till.
Use it for footing drains, curtain drains and infiltration trenches.
3/4 clean covers trench backfill, pipe surround and under-slab drainage.
4, which Washington yards sell as #4 stone.
Rounded stone is a separate family. Natural Pea Gravel, river rock and large round rock suit play areas, dry creek beds, splash pads and swale armour.
Sand, soil and mulch round out an order. Mason sand goes into mortar and stucco, washed sand into concrete and setting beds, and screened topsoil into lawns and grading.

Ground conditions across Pierce County
Pierce County spans more than one ground region. The Puget Sound lowland takes in Tacoma, Lakewood, Puyallup and Graham.
The Cascade Range and the east-slope valleys take in Ashford, Carbonado and Elbe.
In the lowland, glacial ground laid down by the Vashon ice sheet sits under everything. A dense till cap, its lower part hard enough that crews call it hardpan, sits over advance outwash sand and the Lawton beds below that.
That layering drives the drainage problem. Rain soaks the loose upper soil, reaches the dense till and stops.
The water table sits close to the surface all winter instead of draining away.
Anything built on till needs the water taken sideways to daylight. That is why footing drains and washed drain rock do so much of the work here.
Bluff failure follows the same water. Winter rain perching where outwash sand meets clay below it is what puts the coastal and valley bluffs of this area on the landslide maps.
Frost is mild in the lowland. The ground seldom freezes deep, so saturation rather than frost softens a base.
A drive that was firm in August can rut in February.
In the mountains, the working window runs roughly from late spring to early autumn, later at elevation. The west slope sheds heavy rain fast off steep ground, and steep-slope runoff scours road shoulders, ditches and culvert outfalls.
Choosing the right material
Thurston County shares Pierce County's ground: the same Vashon till over outwash sand and the Lawton beds. The base and drainage choices carry over unchanged.
King County also spans the Puget Sound lowland and the Cascade Range and east-slope valleys. The lowland ground is the same till and outwash, so the same washed drainage stone applies.
Lewis County spans more than one ground region too, taking in the Lower Columbia, the Chehalis valley and the Willapa Hills alongside the Cascades. Where the ground differs from Pierce County's, so does what it asks of a base.
