Order Class 2 Base and Crushed Stone in Sonoma County, CA
California Rock Supply delivers gravel, stone and aggregate delivery in Sonoma County, CA, and the ground under your project decides how the base goes in. Soils change over short distances here. Sandy dune and beach soils sit along parts of the shoreline, while heavy clay soils that crack when dry and swell when wet are extensive in the Coast Range valleys and hills.
That matters most for Class 2 base, the standard California base material under drives, pads and pavers. On clay, water sits instead of soaking away, so drainage and compaction matter more than raw depth.
Ground conditions across Sonoma County
Most rain falls from late fall to spring, much of it in a few large winter storms and atmospheric rivers. It soaks into sandy ground quickly but sits on or runs off clay soils and slopes.
Plan around that timing. The dry season from late spring into fall is the main window for base, driveway and paver work. Summer fog is common near the shore, but it is winter rain and saturated clay that hold jobs up.
Erosion follows the same pattern. Hillside runoff and slides on steep slopes show up in winter storms, debris flows can follow intense rain on recently burned slopes, and wave and storm erosion works on sea cliffs and bluffs along the shoreline.
On clay ground, work a base in lifts and compact each one before the next goes down. Where runoff crosses a slope, plan a drainage layer and arm the outlets before the first big storm.
Materials delivered in Sonoma County
Materials are easiest to sort by size, from coarsest to finest. Match the size to the job: heavy stone for slope and drainage work, mid sizes for base and drives, fines for paths and bedding.
Class 2 base is the one to understand first. 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.
Recycled base rock, sometimes called recycled Class 2 base, is Class 2 base made from Road Base or asphalt and is used the same way under drives, patios and slabs. Some California suppliers also sell crushed miscellaneous base, or CMB, for drive and pad subgrade. If you want a compacting, binding material, Crusher Run fits, though California buyers more often ask for Class 2 base for the same job. For surfacing an existing drive or topping a compacted base, look at Driveway Gravel and Walkway Gravel.
For drainage, 3/4" Drain Rock is clean stone with no fines, so water moves through it. 3/8" Crushed Stone suits pipe bedding and topping over a compacted base. 3/4" Crushed Stone works for drainage beds, drive surfacing and construction entrances.
Soils and fills round out a job. Fill Dirt raises grade and backfills before a Class 2 base goes down. Top Soil handles lawn and bed prep over clay, hardpan or sandy native soil.
Choosing the right material
Ground next door is close to Sonoma County's but not identical, and the material choice shifts with it. Mendocino County sits in the North Coast, and its ground zone is the same Coast and Coast Ranges zone. Expect similar clay and sandy soils and similar base and drainage choices, with typical projects running to rural drives and slope work.
Contra Costa County is a Bay Area county in the same ground zone, so the ground is similar again. Work there tends toward tighter lots and driveway and pad base, where compaction on clay decides how the surface holds up.
Solano County is Bay Area but spans more than one zone: Coast and Coast Ranges plus the Central Valley floor. That mix changes things. Ground that drains faster may need less drainage stone, while base still has to carry the load.
Start with what the ground does with water. Clay holds it, so add a drainage layer and compact in lifts. Sandy ground drains fast, so base and edge restraint carry more of the job.
Delivery across Sonoma County
Order online and size the load by the ton or by the yard, whichever suits your project. The calculator helps you set the quantity before checkout. At checkout you pick a delivery date, and a dump truck brings the material to your site.
Delivery covers Santa Rosa, Petaluma, Rohnert Park, Windsor, Healdsburg, Sonoma, Cloverdale, Cotati, Sebastopol, Guerneville, Forestville, Penngrove, Graton and Bodega Bay. Soils change over short distances, so have the drop spot and the ground conditions in mind when you order.
Think about access before the truck arrives. A dump truck needs room to reach the drop point, and where it places the pile shapes how much moving you do afterward. On a slope or a tight drive, plan the spot first.
