Pea Gravel, Stone and Soil Delivery in Corte Madera, CA

California Rock Supply handles gravel and aggregate delivery in Corte Madera, CA, and the ground here decides most of the job. Soils change over short distances, from sandy pockets near the shoreline to heavy clay that swells when wet. That clay is why a driveway or pad needs a compacted Class 2 base under it, not just a layer of rock on top.

Materials for Corte Madera Projects

Winter rain is the driver on most Corte Madera jobs, so drainage stone earns its place early. Clean washed stone has no fines, which lets water pass instead of ponding. Here is how the sizes run, coarsest to finest, and what each one does.

• RipRap, also called rock slope protection, armors slopes, creek banks and culvert outlets against storm runoff.
• 3/4" Drain Rock, sold elsewhere as #57 stone, is the standard clean stone for French drains and drainage trenches.
• Drain Rock covers drywells, downspout runs and the drainage layer behind retaining walls.
• 3/8" Crushed Stone handles fine drainage, pipe bedding and topping over a compacted base.
• Class 2 Base, also called Class II base rock, is the Caltrans-specified base for driveways, parking pads and the layer under pavers and slabs.

For a softer finish, Stone Screenings, or DG, packs firm for paths and patios when it sits over compacted base. Natural Pea Gravel suits walkways, play areas and bedding, and River Cobble works in dry creek beds and decorative borders. On the soil side, Top Soil and Shredded Mulch rebuild beds over clay and hold moisture through the dry season.

Ground and Conditions in Corte Madera

Most rain arrives from late fall to spring, often in a few large winter storms. It soaks into sandy ground quickly but sits on or runs off clay soils and slopes. That is the reason a drainage layer and a properly compacted base matter more here than the surface rock you see.

The dry season from late spring into fall is the main window for base, driveway and paver work. Summer fog near the shore is normal and rarely stops a job. Winter rain and saturated clay are what hold work up, so timing a delivery around that window pays off.

Hillside runoff and slides on steep slopes are the winter concern, along with wave and storm erosion along the shoreline. RipRap on a slope or culvert outlet, and clean drain rock in a trench, are how most Corte Madera sites handle that runoff.
