Cobble and Bulk Aggregates for Santa Cruz, CA

What holds a slope above a storm drain when the winter rain arrives? Coarse stone, placed right. California Rock Supply provides gravel and aggregate delivery in Santa Cruz, CA, from Class 2 base for drives and pads to the heavy rock that armors slopes and swales. Soils here change over short distances, so the material you order does the work.

Materials for Santa Cruz Projects

On the coast side of the county, winter runoff is the job. Waves cut at the bluffs, hillside water runs hard, and saturated clay moves. The materials below go from coarsest to finest and cover the erosion work first, then the drives and paths around it.

Start with RipRap. Caltrans calls placed rock on slopes rock slope protection, and it is what you want where runoff drops fast at a bank or culvert mouth. Cobble and Large River Rock slow water in a swale or dry creek bed without a hard face.

For underground water, Drain Rock and 3/4 inch drain rock are clean stone with no fines, so water moves instead of sitting. Use them in French drains and behind retaining walls. 3/4" Drain Rock is the washed size most drainage trenches call for.

Under all of it, Class 2 Base is the standard California base, specified by Caltrans as Class 2 aggregate base. Recycled base and crushed miscellaneous base do the same work under drives and pads, and Caltrans allows processed reclaimed concrete and asphalt in aggregate base. Stone Screenings packs firm for paths and patios over a compacted base.

Ground and Conditions in Santa Cruz

The dry season from late spring into fall is the window for base, driveway and paver work. Summer fog near the shore is fine to build in. It is winter rain and saturated clay that hold jobs up, so plan the base and drainage before the first big storm.

Most rain falls from late fall to spring, much of it in a few large winter storms and atmospheric rivers. Sandy dune and beach soils along parts of the shoreline soak it up fast. Heavy clay soils in the Coast Range valleys and hills crack when dry and swell when wet, so water sits on them and runs off slopes.

That difference decides your material. On clay, dig the drainage layer and let Class 2 Base sit on stable, compacted ground. On sand, the ground drains itself and the base still needs proper compaction to lock up.
