Fill Dirt in Piedmont Avenue, CA

In the Bay Area, delivered fill-dirt prices vary with quality and screening. Expect material costs roughly $10 to $40 per ton depending on screened vs unscreened and local supply, plus delivery which commonly ranges from a small per-ton surcharge to a flat fee (often $150 to $500) for local trips; Hello Gravel minimum order is 3 tons and many areas have free delivery options. For an exact cost, get a quote through our site since local quarries, availability, and truck access affect price.

Yes—local suppliers around Oakland and Alameda commonly offer both screened (cleaner, fewer roots and large clods) and unscreened fill-dirt (cheaper but dirtier). Screened material is better where you need a tidy finished surface or will be planting; if you want a cheaper bulk raise for non-finish areas, unscreened can work. Specify u0022screenedu0022 in your order notes if you need a cleaner product and confirm with your Hello Gravel representative.

For structural or load-bearing fills aim for roughly 90% to 95% of standard Proctor density; for simple yard grading 85% to 90% is common. Equipment typically used includes plate compactors or jumping-jack rammers for narrow areas and small vibratory rollers (or a small tandem roller) for larger areas; do lifts of 6 to 12 inches loose thickness and compact each lift. If your project is on a slope or near structures, get a soils engineer recommendation before placing large fills.

Per 100 sq ft use these approximate amounts (using 1.25 tons per cubic yard as a mid-range density): 2u0022 = 0.62 cu yd (≈0.8 tons), 4u0022 = 1.23 cu yd (≈1.5 tons), 6u0022 = 1.85 cu yd (≈2.3 tons), 8u0022 = 2.47 cu yd (≈3.1 tons), 12u0022 = 3.70 cu yd (≈4.6 tons). Actual weight varies with moisture and soil type (1.1–1.4 tons/yd3 is common), so order a small overage (5%–10%) or use our calculator for a precise quote.

Fill-dirt can be fine for raising grades and backfilling flat planting areas, but Piedmont Avenue's hills and seasonal rains make drainage and erosion control critical. Avoid clay-rich fill that holds water on slopes; where drainage and slope stability matter, blend in coarser material, use geotextile or retaining structures, and consult a geotechnical engineer for larger fills. For driveways or load-bearing pads on slopes, use road base or engineered fill instead of plain fill-dirt.

Small landscape fills often do not require permits, but any project that changes grade significantly, affects drainage, adds large volumes of fill, or includes retaining walls likely will. Alameda County and the City of Piedmont have specific rules—many jurisdictions require permits or grading plans for larger fills (commonly thresholds like tens of cubic yards). Always check with the City of Piedmont Building Department or Alameda County Planning and Building before ordering large deliveries.

Fill-dirt is mainly mineral soil and is intended to raise grade or fill voids; it is not a good structural base for driveways. Crushed rock or road base is crushed, graded aggregate that compacts into a stable, draining base ideal for driveways and pads. For a durable driveway or under asphalt/pavers you should specify road base or crushed aggregate rather than use plain fill-dirt alone.

Hello Gravel's minimum order is 3 tons and standard delivery is 2+ business days, with a next-day option available for orders placed before noon CST for an extra fee. Deliveries are generally by tri-axle dump truck; drivers may be able to tailgate-spread at their discretion but that is not guaranteed. If you need specialized offloading (bobcat service, precise placement, or hand spreading), arrange that in advance—many suppliers or local contractors can provide those services for an additional fee.

If plain fill-dirt is used under pavers or asphalt without proper compaction and drainage, you can expect some settlement within months to years, leading to bumps, depressions, and joint movement. Proper compaction in lifts, adequate drainage, and using a structural base layer (road base) under the paving greatly extends performance; with good preparation, paved surfaces can last decades. For high-traffic or paved surfaces, use engineered base materials rather than relying on fill-dirt alone.

True u0022fill-dirtu0022 often has higher fines (silt and clay) and is not optimized for drainage or structural compaction. For a balance of compaction and drainage you want a well-graded engineered fill or base—roughly 10%–30% fines, 40%–60% sand, and 20%–30% gravel is a general guideline—but exact gradation should come from a supplier spec or soils engineer. If your job needs both load-bearing capacity and drainage, ask for road base or an engineered aggregate blend rather than standard fill-dirt.
