This is clay ground in the Coast Range valleys, so drainage decides how a job holds up. Most of the winter rain arrives in a handful of big storms, and water that has nowhere to go sits on top of that clay.

Materials for Sebastopol Projects

Drainage is the work that keeps everything else dry. A French drain, a drywell or a downspout run needs clean washed stone with no fines, so water moves through the voids instead of pooling. Here is the lineup by size, coarsest to finest.

For the drainage layer itself, Drain Rock and 3/4" Drain Rock are the two most asked for. Both are washed, so they pass water instead of holding it. Use the coarser stone in deep trenches and the smaller washed sizes where the run is tight.

Above the drainage, Class 2 Base is the standard California base material, specified by Caltrans as Class 2 aggregate base. Contractors here also call it Class II base rock or base rock. Recycled base rock made from Road Base or asphalt does the same job, and Caltrans allows processed reclaimed asphalt and concrete in aggregate base.

For paths and patios, Stone Screenings, or DG, packs firm over a compacted base and handles low-water landscaping. On slopes and creek banks, RipRap is the placed rock that takes the hit from storm runoff. Caltrans calls that rock slope protection.

Delivery to Sebastopol and the Surrounding Area

You order online, set the quantity by the ton or yard, and pick a delivery date at checkout. A dump truck then brings the load to your site. That covers Sebastopol and the rest of Sonoma County, including Santa Rosa, Petaluma, Rohnert Park, Windsor and Healdsburg.

Know where the truck can park and where the pile should land before the date you pick. A dump truck needs a clear approach and enough room to raise the bed. If the driveway is soft from rain, say so at checkout and we can drop the material closer to the street.

Small loads and full truckloads both ship the same way. If you are unsure how much to order, size it with the calculator first and let the number drive the order.

Ground and Conditions in Sebastopol

The dry season from late spring into fall is the main window for base, driveway and paver work. Winter rain and saturated clay are what hold jobs up, not cold. Summer fog near the shore is normal and does not stop compaction.

Soils change over short distances here. Sandy ground near the shoreline drains fast, while the heavy clay in the Coast Range valleys cracks when dry and swells when wet. On clay, plan on a drainage layer and a compacted Class 2 base above it, and keep water moving away from the pad.

Hillside runoff and slides are a winter storm problem on steep slopes, and intense rain on recently burned slopes can move debris. Armor culvert outlets and slope toes with riprap before the first big storm, not after. Reclaimed asphalt and concrete in a recycled base rock work fine for drive and pad subgrade where drainage is already handled.
