Fill Dirt in Occidental, CA

In the Occidental area, bulk fill dirt typically runs about $15 to $40 per cubic yard, or roughly $10 to $30 per ton, depending on supplier, quality, and moisture content. Delivery, minimum order (Hello Gravel minimum is 3 tons), and distance from local quarries or pits can add $50 to $250 or more, so get a delivered quote for an accurate price.

For slope stabilization around Occidental, use clean fill dirt with low organic content and a well-graded mix of sand, silt, and some clay so it compacts well. Avoid topsoil, roots, and large organic debris; for steep or critical slopes combine compactable fill with a free-draining layer (crushed rock) and consider geotextile or engineered fill if an engineer recommends it.

Occidental's wet winters and dry summers mean fill dirt can compact well when placed and moistened, but fine silty or clay-rich fills can shrink and crack during dry spells and become soft in heavy winter rains. Proper compaction in lifts, good surface grading, and installed drainage (swales or French drains) reduce seasonal settlement and erosion risks.

A 10 x 20 x 0.5 ft patio uses 100 cubic feet, which is about 3.7 cubic yards (round up to 4 cubic yards to allow for compaction and waste). Using a common weight range (1.2 to 1.5 tons per cubic yard), expect roughly 4.5 to 6 tons for that project — order a little extra for compaction and grading.

A two-car driveway (about 20 x 20 x 0.5 ft) is roughly 200 cubic feet or about 7.4 cubic yards; round up to 8 cubic yards to account for compaction. That equals approximately 9.5 to 12 tons using common conversion ranges; for a structural driveway base you should plan for a crushed rock or engineered base on top of fill dirt rather than relying on fill dirt alone.

Sonoma County may have local grading, drainage, or environmental rules for moving large amounts of earth or changing drainage patterns, especially on hillsides and near waterways. For small backyard fills you may not need a permit, but always check with Sonoma County Permit and Resource Management Department and any HOA before major grading work.

Local suppliers and haulers often provide bulk delivery by dump truck and may offer optional tailgate spreading at the driver's discretion, but spreading and compaction are not guaranteed through Hello Gravel. For compaction, grading, or engineered placement, most customers hire a local contractor; some suppliers can recommend installation partners for an additional fee.

Use fill dirt to build up or regrade areas and to fill low spots, but for driveways and load-bearing surfaces crushed rock or an engineered base is recommended because they drain better and compact to a stronger surface. For erosion control on slopes, combine compacted fill with drainage layers, geotextile, retaining structures, or crushed rock aprons rather than relying on fill dirt alone.

On Occidental's hills, slope work should include proper grading to shed water, diversion swales, French drains or subdrains where needed, geotextile undercutting to prevent migration, and erosion-control blankets or seed/groundcover to stabilize new fills. For near-stream or steep sites, use retaining walls or terraces and consult Sonoma County rules or a soil engineer to reduce downstream erosion risk.

Hello Gravel sources regionally, so fill dirt is generally available in the West California area; standard delivery is 2+ business days, with next-day delivery available for orders placed before noon CST for an added fee. Seasonal demand, truck availability, and distance from local pits can extend lead times to several days, so check zip-code availability and request a delivered quote for exact timing.

Properly placed and compacted fill dirt can be a durable base for many years, but it is more susceptible to settling and erosion than engineered base materials. Expect periodic visual checks after heavy winters and occasional top-ups or regrading every few years; critical driveways and surfaces perform best with an engineered base and routine maintenance of drainage systems.
