Fill Dirt in San Lorenzo, CA

Typical delivered fill dirt prices in the San Lorenzo area usually fall in a range rather than a fixed price because of local sourcing and truck routing. Expect a per-ton range and delivery fees combined to typically fall between $15 and $45 per ton for most orders in Alameda County, though smaller orders, difficult access, or same-day requests can push costs higher. Hello Gravel shows final, zip-code-specific pricing at checkout and can provide exact delivery fees when you enter your address.

Fill dirt is usually used as a subgrade to raise or level a site, not as a finished driveway surface. For driveways in San Lorenzo you should place compactable, low-organic fill as a subgrade and follow that with a structural base such as Class II road base or crushed rock (3/4u0022 minus or crusher-run) for the wearing layer. If you plan to use fill dirt under a driveway, request screened, low-organic fill and professional compaction to reduce settling.

Large fills or any work that changes site grading, drainage, or creates substantial earthmoving often triggers local permits in Alameda County and may need review by the City of San Lorenzo (check with the county or city planning and public works). Thresholds and requirements vary by project size, site drainage, and proximity to creeks or steep slopes, so contact the Alameda County Planning Department or City public works before ordering large quantities. Hello Gravel recommends checking local permit needs early to avoid delays or rework.

Raise 1,000 sq ft by 6 inches equals 500 cubic feet, which is about 18.5 cubic yards (500 ÷ 27). Fill dirt weight varies with moisture and compaction; a practical planning range is about 1.2 to 1.5 tons per cubic yard, so you would need roughly 22 to 28 tons. Always allow 5-15% extra for settlement and compaction, and use our material calculator or request a quote for a site-specific estimate.

Some local suppliers and contracted haulers in the East Bay may offer same-day delivery for small orders if trucks and materials are available, but it is not guaranteed and usually carries an extra fee. Compaction services are often provided by separate contractors rather than dump truck drivers; some trucking partners may offer tailgate spreading at their discretion but do not guarantee compaction. When you order through Hello Gravel, you can request same-day options or note compaction needs and we will try to match you with suppliers who can help.

Fill dirt is mostly fines and native subsoil, so it drains much more slowly than crushed rock or gravel. In San Lorenzo's coastal/marine-influenced climate and low-lying areas, using fill dirt alone can increase the risk of surface water pooling and slow drying after storms. For sites where drainage matters, put a well-draining layer (crushed rock or Class II base) under or above the fill and consider drainage piping or swales to manage runoff.

Common extra costs include permit fees, export/haul-off of existing material, compaction or grading contractor fees, erosion-control supplies (silt fences, straw wattles), and extra trucking charges for tight access or partial loads. Moisture content that causes the soil to be heavier or muddy can increase per-ton costs and may result in refusal by the hauler on delivery day. Ask for a full quote that lists potential add-ons and check local permitting early to understand inspection or mitigation costs.

It depends on the purpose: for structural support and driveways, Class II base or engineered fill is usually the better choice because it compacts reliably and drains well. For simple landscape grade adjustments where vegetation will be added, imported soil or topsoil blended with clean fill might be preferable for plant health. On sloped San Lorenzo lots, engineered approaches that combine compactable fill, drainage measures, and a proper surface layer are the most reliable—consult a geotechnical or grading contractor for steeper sites.

When properly placed as a compacted subgrade and capped with a structural base and pavement, fill dirt can perform reliably for many years or decades. The key factors are adequate compaction, proper moisture control, and a suitable wearing surface (Class II base, crushed rock, asphalt, or concrete). If fill dirt is used alone without compaction or a stable base, you can expect settlement, potholes, and failures within a few seasons.

Yes—San Lorenzo and Alameda County follow regional stormwater and erosion-control rules that require measures to prevent sediment runoff during grading and delivery, especially near creeks and storm drains. For any significant soil disturbance you may need best-management practices (silt fences, inlet protection) and possibly permits from the county, city, or regional water board. We recommend checking with local public works and including erosion-control plans when ordering large volumes of fill dirt.
