Cobble and Bulk Aggregates for Westport, CA

Start with the math before you start with the truck. Figure the square footage, the depth in feet, then convert to cubic yards, and gravel and aggregate delivery in Westport, CA gets simple from there. California Rock Supply sells bulk material by the ton and the yard, and on this stretch of the Mendocino coast the first order is usually Class 2 base.

Soils here change fast, from sandy shoreline ground to heavy clay that swells when it gets wet. That decides how much stone you need and where it goes.

Materials for Westport Projects

Winter storms drive the material list here. Steep ground and creek banks above town need coarse stone that stays put when water comes off the hills, and the rest of the order is about getting runoff away from the house, the drive and the pad.

• RipRap, also called rock slope protection: placed rock on slopes, creek banks and culvert outlets. Caltrans specifies it as rock slope protection, and it is the first line of defense against winter runoff.
• Large River Rock: cobbles for dry creek beds and swales where you want runoff slowed down before it reaches a culvert.
• 3/4" Drain Rock, also called #57 stone: clean stone with no fines for French drains, drainage trenches and drainage layers behind retaining walls.
• Class 2 Base, also called Class II base rock or Class 2 aggregate base: the standard California base material, specified by Caltrans as Class 2 aggregate base, for driveways, parking pads and the compacted layer under pavers and slabs.
• Stone Screenings, also called DG: a fine, firm-packing surface for paths and patios, laid over that compacted base.

Ground and Conditions in Westport

Most rain arrives from late fall to spring, much of it in a few large winter storms and atmospheric rivers. Sandy ground soaks it up fast. Clay soil and slopes shed it, and that is where your problems start.

On clay, the water sits on top until it finds a seam. That means a drainage layer under the base and a real outlet at the bottom of the slope, not a stone pile with nowhere to go.

The dry season from late spring into fall is your window for base, driveway and paver work. Winter rain and saturated clay are what hold a job up, so time the delivery to the dry stretch and get the slope work done before the storms.
