Measure area in square feet, multiply by depth in feet to get cubic feet, then divide by 27 to get cubic yards; multiply cubic yards by the weight factor (typically 1.0 to 1.6 tons per cubic yard for fill-dirt depending on moisture and composition). For example, 1,000 sq ft at 4 inches (0.333 ft) is about 12.3 cubic yards; using 1.2 tons/yd3 that equals about 15 tons. Round up and add 5-10% for settlement and compaction when ordering.

For hilly driveways, use clean, compactable fill-dirt with low organic content and good gradation, or combine fill-dirt with a layer of crushed rock/base material for structural support. Because Napa has wet winters and dry summers, proper drainage and compaction are critical to avoid erosion and settling. Consider an engineered base (crusher run or class II aggregate) topped with compacted fill-dirt where needed rather than fill-dirt alone.

Fill-dirt can be used for general backfill if it is free of organics and compacted to the engineer's specification, but foundations and septic systems often require engineered fill approved by a geotechnical or civil engineer. Napa County Environmental Health has strict rules for septic systems and may require specific materials and tests before accepting imported soil. Always confirm permit and design requirements with the local building or environmental health department before importing fill-dirt for these uses.

Small residential fills are usually placed in lifts (commonly 6 to 8 inches) and compacted to 90-95% of the standard Proctor density for structural work; compaction testing may be required for permitted work. Costs vary by crew size and equipment; expect separate fees for placement and compaction if you hire a contractor, plus possible laboratory testing costs for compaction verification. Hello Gravel provides delivery; spreading and compaction are typically arranged with local contractors unless the driver agrees to tailgate spread at their discretion.

Fill-dirt is intended to raise grade and provide bulk material; it compacts but usually contains more fines and may hold water compared with crusher run. Crusher run and class II base are engineered for structural support and drainage and are better for driveways and areas needing load-bearing capacity. Decomposed granite is decorative and permeable but not as strong for structural loads; choose based on whether you need bulk fill, structural base, or a finished surface.

Permitting depends on the project scope: small grading and landscaping often do not need permits, but larger grade changes, foundation work, or septic-related imports commonly require permits and inspections from Napa County. Importing soil may also trigger environmental rules if soil is considered ‘clean fill’ or potentially contaminated; check with Napa County Building and Environmental Health before ordering. If in doubt, contact our sales team and your local building department to verify requirements.

Hello Gravel delivers via dump trucks; drivers may perform tailgate spreading at their discretion and when it can be done safely. For steep or tight-access sites, you may need smaller trucks, an offload point, or machine assistance (skid steer, mini-excavator) to move material; plan for additional labor or equipment fees. Add delivery notes at checkout and discuss site access with our team so suppliers can match the right truck and crew to your property.

A driveway that uses fill-dirt alone will need regular maintenance; with proper compaction, drainage controls, and a durable surface topping (crushed rock or asphalt), the base can perform well for many years. Expect occasional regrading and replenishing of surface material after heavy winter rains, and inspect for erosion on slopes. For long-term low-maintenance driveways, use compacted engineered base materials topped with appropriate surfacing rather than relying solely on fill-dirt.

Ask your supplier for a description of the material source and specification (clean fill, no organics, free of debris) and request photos or a sample when possible. Avoid materials labeled as mixed demolition or unknown origin without testing; consider a basic soil test if you suspect contamination or need specific engineering properties. Hello Gravel lists local supplier details so you can review material notes and contact our team with questions before confirming your order.

Clear the delivery path of vehicles and low branches, mark the desired drop location with flags or stakes, and call 811 to have utilities located if digging will follow. Make sure gates are unlocked and provide detailed delivery notes at checkout; our minimum order is 3 tons and drivers will assess access upon arrival. If you need spreading or compaction, schedule a local contractor in advance since drivers may only tailgate spread at their discretion.
