Fill Dirt in Santa Rosa Valley, CA

A typical tri-axle dump truck in our network delivers about 10 to 12 cubic yards of fill dirt (roughly 12 to 15 tons depending on moisture and compaction). Delivered price in Santa Rosa Valley usually varies by local supplier and haul distance; expect a broad range of roughly $400 to $1,000 for a full truck delivered, though smaller orders (we have a 3-ton minimum) will be priced differently. For an exact price, use our quote tool or contact Hello Gravel with your zip code and delivery address.

Fill dirt is generally cheaper per ton than crushed gravel and is commonly used for bulk grading and raising low areas. For a driveway base in Santa Rosa Valley, compacted crushed rock or a contractor-grade base material (such as CA-6) is recommended because it drains and compacts better than plain fill dirt. Order fill dirt for bulk fill and rough grading, and order compactable base rock or gravel for driveways and final base layers.

You should not rely on loose fill dirt alone for a driveway or patio surface. Santa Rosa Valley projects require compaction in layers (lifts) and often a structural base of crushed rock or engineered fill to prevent settling and provide drainage. We recommend planning for compaction and a proper base—Hello Gravel can deliver the materials you need, but compaction and installation are typically handled by a contractor or equipment rental.

Coarse fill with occasional rocks is fine for rough grading and bulk fills, but screened or clean fill is preferred for final grades, landscaping over topsoil, or under patios and slabs. If you need a smooth finish or easy compaction, request screened/clean fill in the order notes. Because we source regionally, material texture will reflect local geology, so note u0022screenedu0022 or u0022cleanu0022 when you check out if that matters to your project.

For 1,000 sq ft the approximate volumes are: 1 inch = 3.09 cu yd, 2 inches = 6.17 cu yd, 3 inches = 9.26 cu yd, 4 inches = 12.35 cu yd, and 6 inches = 18.52 cu yd. Fill dirt is typically sold by the cubic yard or ton rather than 50 lb bags; convert to tons using roughly 1.1 to 1.5 tons per cubic yard depending on moisture and compaction. Use our material calculator or contact Hello Gravel for a precise estimate for your site.

Hello Gravel primarily supplies and delivers materials; tailgate spreading by the driver may be possible at their discretion but is not guaranteed. Compaction and full installation are usually provided by local contractors; typical rental costs to expect are plate compactors around $75 to $150 per day and skid-steer or compactors $250 to $700 per day, while contractor labor for site prep and compaction commonly runs in the range of $50 to $100 per hour. Ask our team for local contractor recommendations or include installation notes at checkout and we can flag potential partners.

Confirm site access for a tri-axle dump truck (turning radius, gate width, overhead wires, and driveway surface), and give clear delivery location notes at checkout. Check with the City of Santa Rosa or Sonoma County Planning for any grading, import, or erosion-control permits—some projects on slopes or in sensitive areas require permits or best-management practices. Also clear vegetation where the truck will dump and confirm there is room to stockpile material if you are not spreading it immediately.

Stabilizing fill dirt typically involves compaction in lifts, geotextile fabric, terraces or retaining walls, and surface treatments such as gravel, crushed rock, or vegetation. Hello Gravel can supply materials you will need—fill dirt, crushed rock, drainage rock, and geotextile fabrics—but compaction and engineered stabilization work are best handled by a licensed contractor or civil engineer for slope work. For small landscape slopes we can recommend materials and typical approaches; for larger or structural work, consult a local engineer familiar with Sonoma County conditions.

Yes—Hello Gravel can supply drainage rock, larger aggregate for French drains, and geotextile (filter) fabric; these materials are commonly available from our local suppliers. Material costs delivered to Santa Rosa Valley typically range from about $40 to $150 per cubic yard for drainage rock depending on size and source, and filter fabric often costs roughly $0.50 to $2.00 per square foot; installation labor varies by contractor and site conditions. We can deliver the materials you need and can help connect you with local installers if you want a bundled quote.

Sonoma County and the City of Santa Rosa have regulations around grading, erosion control, and, in some cases, imported fill—especially for larger projects or in sensitive areas. Hello Gravel sources materials regionally and can request clean-fill documentation from suppliers on your behalf, but customers should confirm permit and testing requirements with local authorities for their specific project. If you need documentation, add that request to your order notes or contact our team so we can flag suppliers that can provide certificates when available.
