Fill Dirt in Boyes Hot Springs, CA

Fill dirt is subsoil material with minimal organic matter used to raise low spots, build pads, or fill trenches. In Boyes Hot Springs it is commonly used to level yards, create building pads, and correct grades before landscaping or paving, but it is not usually used as a finished driveway surface without a stable top layer.

Local delivered prices vary by supplier, haul distance, and site access, but expect roughly $18 to $45 per cubic yard or about $15 to $35 per ton as a ballpark range. Get a specific quote through Hello Gravel because regional sourcing, truck routing, and minimums affect the final price.

For grading and raising areas in this climate, choose clean, well-graded fill free of roots and organic material so it compacts predictably. For a driveway base, use engineered fill or road base and top with crushed rock or decomposed granite; plain fill dirt alone is inexpensive but not ideal for a finished driving surface.

Measure length x width x depth in feet, divide by 27 to get cubic yards (L x W x D / 27). To convert to tons, multiply cubic yards by about 1.2 to 1.5 (density varies), for example a 12 ft x 30 ft area at 4 inches deep is about 4.4 cubic yards or roughly 5.5 to 6.6 tons.

Minimum order is 3 tons through our platform and deliveries are made by local contracted dump trucks (typically tri-axle). Standard delivery takes 2 or more business days, next-day may be available if ordered before noon CST for an extra fee, and delivery fees depend on supplier distance and site access so request a quote at checkout.

Fill dirt can help regrade slopes, but it is not a standalone erosion-control finish. Compact fill in 4 to 6 inch lifts with a plate compactor or small roller, install erosion-control fabric, and add vegetation, mulch, or rock armoring to protect exposed slopes from winter rains.

Fill dirt is best for raising grade and backfill but is poor for surface loads and drainage. Road base or crushed rock provides a stable, compactable base for driveways, while decomposed granite offers a natural-looking, permeable surface for paths in dry climates; choose based on load, drainage needs, and finish appearance.

Permitting depends on the scope of work; small landscaping deliveries usually do not require a permit, but significant grading, changes to drainage, or building pads often require Napa County permits or plan review. Check with the Napa County Planning or Public Works department before ordering large volumes to avoid stopping work or regrading.

Compacted fill dirt can perform well for many years if properly compacted and kept stabilized with good drainage, surfacing, or vegetation. Expect some settling and occasional regrading after heavy rains, so include erosion control and a durable wearing surface (gravel or pavement) where traffic or washout is likely.
