Cobble, Stone and Soil Delivery in Cottonwood, CA

What do you order when winter storms push water at a bank, a swale or a culvert outlet? The answer is coarse stone, and gravel and aggregate delivery in Cottonwood, CA starts there. California Rock Supply stocks the heavy sizes that hold ground in place, plus the Class 2 base you compact under a drive or slab.

Cottonwood sits on deep valley alluvium in Shasta County, where heavy clay and hardpan stop water from draining down. That is why the right stone matters more here than the right volume of dirt.

Materials for Cottonwood Projects

Erosion work runs on size. The coarsest stone goes where water moves fastest, and the finer material goes where you need a firm, walkable or drivable surface. Start at the heavy end.

• RipRap, also called rock slope protection, is the go-to for creek banks, slope faces and culvert outlets. Caltrans specifies placed rock on slopes as rock slope protection for exactly this job.
• Large River Rock slows runoff in dry creek beds and swales. Rounded cobble lets water pass while it breaks the energy that scours a channel.
• Railroad Ballast is the heaviest drainage stone on the list. Use it for hard standing, track beds and severe drainage where nothing finer will stay put.
• 3/4" Drain Rock, also called #57 stone, is clean washed stone with no fines, so water moves straight through it. It is the standard for French drains and drainage trenches.
• Drain Rock handles drywells, downspout runs and the drainage layer behind a retaining wall.

Once the water is managed, the finer end takes over. Class 2 Base, also called Class II base rock or Class 2 aggregate base, is the California standard for driveways, parking pads and the compacted base under pavers and slabs. Driveway Gravel tops an existing drive, and Stone Screenings gives paths and patios a firm, fine surface over that base.

Ground and Conditions in Cottonwood

Plan your work around the long, hot, dry season from late spring into fall. That is the window when clay is firm enough to compact and trucks can reach a site without cutting ruts.

Winter is the problem. Rain arrives from late fall to spring in winter storms and atmospheric rivers, and on flat clay and hardpan ground water has nowhere to go. It ponds. So drainage gets built in, not added later.

Two consequences follow. First, any drive or pad needs a drainage layer under or beside it, which is where 3/4" Drain Rock and Drain Rock earn their place. Second, base depth and compaction matter more than thickness alone: Class 2 base placed over soft, wet clay will not hold, so build up grade with Fill Dirt first and compact in lifts.

Erosion risk here is not hillside wash. It is high water and bank erosion along rivers, creeks and levees during large storms. That is RipRap and cobble territory, placed at the outside bend and at any outlet where flow concentrates.

Delivery to Cottonwood and the Surrounding Area

California Rock Supply delivers bulk material across Cottonwood and the rest of Shasta County, including Redding, Anderson, Shasta Lake, Bella Vista and Palo Cedro. Order online and choose your quantity by the ton or by the yard.

Lead time depends on the material and the haul, so order before you schedule the excavator rather than after. Heavy stone like RipRap and Railroad Ballast moves on its own schedule, and it helps to have that on site before the crew starts.

Tell us where the truck can safely dump. A firm, dry, reachable spot near the work keeps the load where you need it and saves you moving stone twice.
