Order Class 2 Base and Crushed Stone in Modoc County, CA
California Rock Supply delivers gravel, stone and aggregate delivery in Modoc County, CA. The working window here runs late spring to fall. Snow and frozen ground stop most base and excavation work in winter, and the spring thaw leaves unpaved ground soft. Plan a Class 2 base order for that window. Class 2 base is the standard California base under drives, pads and pavers.
Ground Conditions Across Modoc County
Most soils here are thin and rocky over granite, volcanic or metamorphic rock. Granite has weathered coarse and sandy in places. Some valley and basin floors between ranges hold deeper soil. A thin base over that ground shows its first failures at the edges and in the wheel tracks, where the material ravels and ruts form after a wet spring.
Winter storms bring rain and snow, and melting snow keeps the ground wet into spring. Water runs fast off rock and thin soil on slopes. It collects where drives and pads cut across it. That is why a compacted base needs a drainage layer under and beside it, not just more stone on top.
Freeze-thaw is a real design factor. Freezing nights are routine through winter. Snow is heavy and lasting at the highest towns and lighter, occasional or short-lived at lower ones. Frost depth is set by the local building department, 18 to 24 inches in mountain towns such as Big Bear Lake, Truckee and Mammoth Lakes. Snowmelt and storm runoff on steep slopes and unpaved roads drive erosion.
Materials Delivered in Modoc County
Class 2 base is the material most Modoc County jobs start with. California specifies aggregate base by Caltrans Standard Specifications Section 26 as Class 2 or Class 3, in a 3/4 inch or 1-1/2 inch maximum grading. Class 2 is the higher-strength grade. It is the common base under drives, pads and pavers, and under Stone Screenings paths. The spec allows processed reclaimed asphalt and concrete, which is why recycled Class 2 base is widely sold. Recycled base rock and crushed miscellaneous base, often called CMB, are Class 2 base made from Road Base or asphalt and used the same way.
Crusher run is also ordered where a compacting, binding material is wanted, though California buyers more often ask for Class 2 base for the same job. For drainage layers, 3/4 inch drain rock and 3/4 inch crushed rock both work. Natural Pea Gravel and mason sand cover play areas, walkways and paver joints, and washed sand handles bedding under slabs.
Delivery Across Modoc County
You order online. Choose a quantity by the ton or the yard, size the load with the calculator, and pick a delivery date at checkout. A dump truck then delivers to the site. The calculator is the fastest way to settle a quantity, since it turns your area and depth into the amount to order.
Bulk delivery covers Alturas, Cedarville, Canby, Fort Bidwell, Adin, Lake City and Davis Creek. Have the drop spot clear before the truck arrives. Soft ground in spring can limit where a loaded truck can go, so a firm, level spot helps.
Choosing the Right Material
Ground conditions shift as you move between counties, and the base choice shifts with them. Siskiyou County and Lassen County sit in the same ground zone as Modoc County, so the ground is similar. Thin, rocky soil and the same freeze-thaw pattern mean the same approach: a compacted Class 2 base over a drainage layer. The projects differ more than the material does.
Shasta County spans more than one zone, including the Central Valley floor and the Sierra Nevada foothills. Lower, deeper ground there holds moisture differently and drains slower, so drainage matters more than frost. Modoc County ground drains fast and freezes hard, which puts the emphasis on compaction and edge protection.
