Bulk Material Delivery in Stonyford, CA

What do you order for gravel and aggregate delivery in Stonyford, CA? It depends on the job. For a driveway or a pad, start with Class 2 base, the standard California base material, specified by Caltrans as Class 2 aggregate base. For slope and bank work, you want coarse stone. California Rock Supply delivers both, ordered online and dumped at your site.

Around Stonyford, heavy clay soils in the Coast Range valleys crack when dry and swell when wet. That shapes what you order.

Materials for Stonyford Projects

Winter storms drive the material choice here. Hillside runoff moves fast, and water that sits on clay has to go somewhere. Coarse, clean stone is how you slow it and steer it. Here is the range by size, coarsest first.

Coarse stone for slope, swale and bank protection

RipRap, also called rock slope protection, is the heavy end. Use it on creek banks, culvert outlets and steep slopes where winter runoff hits. Caltrans calls placed rock on slopes rock slope protection, and that is how this material is specified on bank and channel work.

Large River Rock works in dry creek beds and swales where you want runoff slowed rather than blocked. Round cobble sheds water and holds the channel shape.

Drainage stone

Drain Rock is clean stone with no fines, so water moves through it. French drains, drywells, downspout runs and the drainage layer behind a retaining wall all take it. Where you need a washed size for a drainage bed or a construction entrance, 3/4" Crushed Stone is the common pick.

Base and surfacing

Class 2 Base, also called Class II base rock, is the compacted layer under driveways, parking pads, pavers and slabs. It is the same material whether you call it Class 2 aggregate base or base rock. If the subgrade needs building up first, Fill Dirt goes down before the base. Topping an existing drive is a job for Driveway Gravel.

Ground and Conditions in Stonyford

The dry season from late spring into fall is your window for base, driveway and paver work. Winter rain and saturated clay are what hold jobs up here, not cold. Most rain falls from late fall to spring, much of it in a few large storms, and it soaks into sandy ground quickly but sits on or runs off clay soils and slopes.

That is the practical reason to compact Class 2 base in dry weather and to get drainage stone in before the first big storm. On clay, water that has nowhere to go will find the weak spot in a driveway or a slab edge. Slopes above a building or a drive need armoring, because hillside runoff and slides are the winter problem in the Coast Range.
