Fill Dirt in Danville, CA

Prices vary by supplier and exact material, but delivered fill dirt in Danville commonly ranges from about $20 to $50 per ton, or roughly $25 to $60 per cubic yard. Costs depend on distance, screening (screened vs un screened), truck access, and whether spreading or hauling surcharges apply. Get a quote for your zip code for an exact price.

For structural fills (under driveways or foundations) contractors in Danville typically place fill in 4 to 8 inch lifts and compact each lift to about 90% to 95% of standard proctor density. For non-structural grading (yard leveling) 85% to 92% may be acceptable, but local engineer or building department requirements control near structures. Always confirm compaction specs with your engineer or permit plan.

Use a low-organic, well-graded engineered fill or screened fill dirt for slope stabilization and general grade raising; it compacts well and resists excessive settling. For drainage areas, add a layer of coarse granular material or drain rock instead of fine fill dirt to maintain flow. For garden topsoil, order topsoil or a blend rather than fill dirt, since fill dirt lacks organic matter and nutrients.

Multiply area by depth in feet: 1,000 sq ft x 0.5 ft = 500 cubic feet, then divide by 27 to get cubic yards: 500 / 27 = about 18.5 cubic yards. Add 10% to 15% for compaction and waste, so plan on about 20 to 21 cubic yards. If you need tons, use an estimated weight of 1.1 to 1.3 tons per cubic yard for compacted fill dirt, so 20 cy equals roughly 22 to 26 tons.

Many local suppliers offer screened fill dirt but minimums vary; Hello Gravel has a platform minimum of 3 tons, while individual suppliers or haulers commonly set minimums at one tri-axle load (about 10 to 15 tons) for residential deliveries. Screened material may have higher minimums or distance charges, so request a detailed quote during checkout and ask about smaller loads or split deliveries if needed.

Bringing multiple truckloads into a Danville residential area can trigger local rules like temporary parking restrictions, encroachment permits, or traffic control, especially if trucks block travel lanes or sidewalks. Always check with Town of Danville Public Works or your homeowners association before scheduling many truck drops, and tell Hello Gravel about special access or permit requirements so we can coordinate with the hauler. Haulers may also require a staging area and clear access to the drop location.

Yes, Danville contractors commonly use a crushed rock or Class II base layer under driveways and paved areas to create a stable, well-draining foundation and reduce long-term settling. Fill dirt alone is not a reliable wearing surface; combine compacted engineered fill with a structural base and proper drainage for driveways. Your contractor or local building permit will specify the required base thickness and compaction level.

Danville has a Mediterranean climate with wet winters (roughly November through March), and suppliers often avoid loose placement or spreading during heavy rain to prevent tracking, rutting, and poor compaction. Schedule major fill work in the drier months (spring through fall) when possible, and if winter placement is necessary, expect delays or additional fees and an on-site assessment by the driver. Always request a delivery date that accounts for local weather and ground conditions.

When properly engineered, compacted, and surfaced, a fill dirt base under a driveway can perform for many years, but loose or uncompacted fill used for surfacing will settle and need material added or regrading every 1 to 5 years depending on use and drainage. Regular maintenance includes checking drainage, topping low spots, and re-compacting after heavy storms. For driveways, adding a structural crushed base and surfacing (asphalt, pavers, or rock) greatly reduces maintenance frequency.

Deliveries are typically made by tri-axle dump trucks; Hello Gravel requires a 3-ton minimum but most deliveries are full truckloads (10 to 20 tons). Drivers may offer tailgate spreading at their discretion; bobcat work, compacting, and detailed grading are usually provided by contractors or supplier crews for an extra fee—request these services when ordering so we can confirm availability. List access notes, slope concerns, or equipment needs in the Order Notes to help the hauler prepare.

Parts of Danville have clayey or loamy soils that hold water and can shrink-swell, which increases settlement risk if you use high-organic or unengineered fill. For slope work or near structures, choose low-organic, well-graded engineered fill and ensure proper drainage to limit moisture changes. When in doubt, consult a geotechnical engineer for larger grade raises or projects near foundations.
