Fill Dirt in Mariposa, CA

Fill dirt is subsoil with minimal organic material used to raise or level grades, backfill foundations, or fill low spots. In Mariposa's Sierra foothills you’ll use fill dirt to build pads, fix drainage grades, or create uniform subgrades before installing gravel or landscaping. It is not a topsoil substitute for planting; use topsoil or amended mixes for gardens.

Prices vary by supplier, haul distance, and truck access, but bulk fill dirt in Mariposa commonly ranges from about $12 to $35 per cubic yard delivered. Per-ton pricing is roughly $7 to $20 per ton as a rough equivalent, depending on density and regional rates. Spreading is typically a driver-discretional service and may add a fee; always request a delivered quote for an accurate price.

Common dump truck sizes serving Mariposa include smaller 6-8 cubic yard singles, 10-12 yard tandems, and tri-axle trucks that carry roughly 12-16 cubic yards loose. Local hauler truckload charges depend on distance and access but often range from roughly $150 to $400 per load for nearby deliveries, with higher costs for remote driveways or short hauls. If you need full-truck pricing, ask for a truckload quote based on your delivery address.

If your driveway is 20 feet long and a single-car width (about 10 feet wide), the area is about 200 sq ft; at 4 inches depth you need about 2.5 cubic yards, at 6 inches about 3.7 cubic yards. For a stable driveway, use fill dirt only to build or level the subgrade, then add a compacted base of crushed rock (4 to 8 inches of compacted crushed stone) and a surface wearing layer like 3/4u0022 crushed rock or gravel. Compact all layers in 3- to 4-inch lifts with proper compaction equipment; fill dirt alone is not a durable driving surface.

Most suppliers can deliver fill dirt to Mariposa sites, but compaction and trench work are usually performed by contractors with compactors or excavators rather than material haulers. Some haulers partner with contractors who will compact backfill on request; expect additional service charges (commonly $100 to $500+) depending on scope and equipment needed. Ask us to coordinate delivery and we can flag compaction needs so you get bundled estimates.

Yes — Mariposa County has narrow, winding roads and some bridges or private roads with weight or size limits, and tight residential driveways are common in the area. Heavier truck access, local road restrictions, or homeowners association rules can require alternate delivery spots or permits. Tell us about driveway width, overhead clearance, and local restrictions when you order so suppliers can plan the right truck and avoid delays.

For improving drainage, washed coarse sand, open-graded gravel, or 3/8u0022 to 3/4u0022 crushed drain rock are commonly used as subdrain layers or to break up poorly draining native soils. Suppliers in the Mariposa area often offer blended mixes (sand + small gravel or soil blends) for a fee or can source drain rock or pea gravel by the yard. For planting beds, consider mixing in compost and coarse sand rather than using straight fill dirt to improve drainage and fertility.

You can estimate cubic yards with: cubic yards = (area in sq ft * depth in inches) / 324. For 1,000 sq ft that is about 6.2 yd3 at 2u0022, 12.3 yd3 at 4u0022, and 18.5 yd3 at 6u0022. At a typical delivered fill-dirt range of $12 to $35 per cubic yard the material cost would be roughly $75 to $650, plus delivery and any spreading/compaction fees — request a site-based quote for precise totals.

Yes, options exist: bagged fill (sold by the pallet) and smaller truck deliveries (mini-dump or contractor pickups) are available but typically cost more per cubic yard than bulk loads. Hello Gravel's minimum order is 3 tons for bulk delivery, and per-yard prices usually drop for larger bulk orders; ask about mini-dump fees or bag pricing if you need a small amount. For very small jobs, buying bagged material from a local retailer can be more convenient despite a higher unit price.

Yes — you can order fill dirt on Hello Gravel's website or by phone; we connect you with local suppliers and provide haul-to-site pricing based on your address. Enter your delivery address or ZIP code so we can factor access, distance, and truck type into the quote, and let us know if you need spreading or special placement so we can include any extra fees.

In Mariposa, winter rains and wet ground can slow deliveries and limit access; expect longer lead times in late fall through early spring and potential scheduling constraints after storms. Summer and early fall often have the shortest lead times but can see higher demand for landscaping and driveways. Standard lead time is 2+ business days for many areas, with next-day options possible when arranged early; ask for a local availability estimate when you request a quote.
