3/4 Inch Crushed Rock and Bulk Aggregates for Sierra City, CA

California Rock Supply handles gravel and aggregate delivery in Sierra City, CA, from bulk base material to washed drainage stone. Most jobs here start with Class 2 base, also called Class II base rock, for drives and pads. This is mountain ground: thin, rocky soil over granite, with runoff that moves fast once the snow lets go. Drainage is the material decision that matters most.

Materials for Sierra City Projects

Winter storms and spring snowmelt send water down every slope in Sierra County. Washed stone, French drains, drywells and downspout runs are how you keep that water away from a drive, a pad or a foundation. Materials below run coarsest to finest.

Drainage stone

RipRap, also called rock slope protection, armors creek banks, culvert outlets and steep slopes against storm runoff. RipRap is placed rock, not compacted fill. For heavy trench bottoms and construction entrances, #4 Crushed Stone carries water and holds up under traffic.

For French drains, drywells and downspout runs, 3/4" Drain Rock is the standard clean stone. It has no fines, so water passes through it instead of pooling. Drain Rock works the same way behind retaining walls and around footing drains. A smaller washed option, #67 Stone, fits pipe bedding and tighter drainage trenches.

Base and drive material

Class 2 base is the standard California base material, specified by Caltrans as Class 2 aggregate base. Use it under pavers, slabs and Stone Screenings paths. Recycled base rock, made from Road Base or asphalt, does the same job under drives and patios. Class 2 Base compacts firm and drains better than native ground.

Above a compacted base, Driveway Gravel surfaces an existing drive or tops a base layer. 3/8" Crushed Stone works for fine drainage and topping over a compacted base.

Finishing and landscape material

Stone Screenings, also called DG, is a fine, firm-packing path and patio surface laid over a compacted base. See Stone Screenings. Natural Pea Gravel suits walkways and play areas. For beds and dry creek beds, River Cobble and Large River Rock slow runoff and hold decorative beds in place.

Ground and Conditions in Sierra City

The working window runs late spring to fall. Snow and frozen or saturated ground stop most base and excavation work through winter, and the spring thaw can leave unpaved ground soft. Time a delivery for the window when your ground is ready, not before.

Freeze-thaw is a real design factor here. Freezing nights are routine in winter, and snow is heavy and lasting. Frost depth is set by the local building department, 18 to 24 inches in mountain towns. That affects footing depth, not the gravel base you compact under a drive.

Soils are mostly thin and rocky over granite, coarse and sandy where granite has weathered. Water runs fast off rock and thin soil on slopes, then collects where drives and pads cut across it. A clean drainage layer under and beside those cuts is what keeps a base from pumping and shifting after a wet spring. Snowmelt and storm runoff on steep unpaved roads drive most of the erosion here.
