Bulk Gravel and Stone Delivery in Amador County, CA
California Rock Supply handles gravel, stone and aggregate delivery in Amador County, CA, and Class 2 base is the material most orders start with. It is the standard California base, called Class II base rock or class 2 aggregate base by local crews. Soils here are rocky hillside ground, often shallow over bedrock, with clay in many areas and fast-draining Stone Screenings in others.
That mix decides what you order. Drives, pads and patios need a base that compacts hard, drainage stone needs to be clean, and slopes need rock that holds when winter rain runs off.
Ground Conditions Across Amador County
Start with water and where it goes. Heavy winter rain sheets off shallow soil and bedrock on slopes. Clay pockets hold it instead.
Drives and pads need to shed water, and runoff from the slope above needs a path that does not cross your work. Clean stone under and beside the work gives that water somewhere to go.
Erosion follows the same runoff. Steep slopes, drives and road cuts move in heavy winter rain, and burned slopes can move faster. Rip rap armors those spots.
Timing matters too. Work runs best from late spring into fall.
Materials Delivered in Amador County
Materials are grouped the way crews ask for them: base, washed stone, sand, soil, and decorative rock.
Class 2 base carries the most weight here. California aggregate base is specified by Caltrans Standard Specifications Section 26 as Class 2 or Class 3 aggregate base, in a 3/4 inch or 1-1/2 inch maximum grading. Class 2 is the higher-strength grade and the common base under drives, pads and pavers. Class 3 is a lower-strength grade. The spec allows processed reclaimed asphalt and concrete, which is why recycled Class 2 base is widely sold.
You will hear recycled base rock, recycled class 2 base, crushed miscellaneous base or CMB for that recycled version. It goes down the same way, under drives, patios and slabs. All of those names point to Class 2 Base.
Washed stone handles water. Drain Rock covers French drains, drywells, downspout runs and drainage behind retaining walls. 3/4" Crushed Stone works for drainage beds, drive surfacing and construction entrances, and 3/8" Crushed Stone handles fine drainage, pipe bedding and topping over a compacted base. Sizes run down through #67 Stone, #4 Crushed Stone, #8 Crushed Stone and #89 Crushed Stone for joints and tight bedding, with Railroad Ballast for hard standing and severe drainage.
Sand, soil and mulch round out an order. Mason Sand for brick, block and paver joints, Washed Sand for leveling and bedding under slabs, and Washed Sand for coarse leveling and bedding. For planting, Top Soil builds up beds over clay or hardpan, Garden Soil fills raised beds, and Fill Dirt raises grade before a base goes down. Shredded Mulch holds moisture through the dry season.
Decorative rock finishes the yard. River Cobble for beds and dry creek beds, Large River Rock for swales and heavier erosion work where runoff needs slowing, and Natural Pea Gravel for play areas, walkways and bedding.

Choosing the Right Material
Amador County sits in the Sierra Nevada foothills and the hills around the northern Sacramento Valley, on rocky hillside soils with clay pockets and fast-draining Stone Screenings. That is the ground your order has to work on.
Next door in Sacramento County, the ground is deep valley alluvium with heavy clay that cracks in summer in the flood basins and along the valley edges. A cemented hardpan a few feet down across parts of the valley stops water moving deeper. Pads there sit on flatter ground, so drainage layers and clean stone matter more than slope armoring.
Alpine County is mountain ground, with thin rocky soils over granite, volcanic or metamorphic rock and deeper soils on some basin floors. Ground that coarse and shallow drains fast and holds less, so base choice leans on compaction and clean stone rather than clay management.
El Dorado County spans more than one zone, the foothills and the mountains, so its ground is similar to Amador's in the lower country and rockier higher up. If you are working the foothill side, the base and drainage calls look much like here.
