Fill Dirt in Visitacion Valley, CA

Delivered fill-dirt prices in Visitacion Valley usually vary with availability and haul distance; expect a typical delivered range of about $25 to $60 per ton, though Bay Area demand can push prices higher. Delivery fees may be waived for larger orders but can run up to a couple hundred dollars for short loads or difficult access; check our checkout for exact, upfront pricing for your zip code.

Fill-dirt commonly weighs about 1.2 to 1.5 tons per cubic yard depending on moisture and compaction. For quick estimating: one cubic yard covers 324 sq ft at 1 inch depth, so a 4-inch layer uses about 0.0123 cubic yards per sq ft, or roughly 0.015 to 0.018 tons per sq ft; multiply by your area to get a tonnage estimate.

Fill-dirt can be used on slopes and for minor grading, but Visitacion Valley's coastal microclimate and local clay-rich pockets mean you should prioritize drainage and compaction. For slope stabilization or drainage swales we recommend combining properly compacted fill-dirt with drainage rock, geotextile, or engineered solutions and consulting a contractor for steeper slopes.

Clay-heavy soils common in parts of the Bay Area retain moisture and are prone to settlement and poor drainage, so imported fill-dirt will need tighter compaction and moisture control. Sandy or granular native soils drain better and compact predictably; in mixed conditions contractors often use geotextile separation and compact in 4- to 6-inch lifts to avoid future settling.

San Francisco has grading, building, and stormwater rules that may apply if you change elevations, add more than a nominal amount of fill, or affect drainage. Permit thresholds vary by project, so contact the San Francisco Department of Building Inspection or Planning Department before ordering larger loads; Hello Gravel can help you get quantities and documentation for permit applications.

For driveway bases, clean compactable granular material (road base or crusher run) is preferred under fill-dirt; fill-dirt alone is often used as subgrade but should be capped with a granular base for vehicles. For utility trenches, use free-draining sand or pea gravel around pipes and well-graded compactable fill in lifts above that to prevent settlement and protect the utilities.

Longevity depends on compaction, drainage, traffic, and soil type; a well-compacted, well-drained fill-dirt subgrade can perform for many years, but in clay-prone spots you may see settlement or soft spots within 1 to 5 years. Proper initial compaction, geotextile, and good surface drainage greatly reduce the need for regrading.

Fill-dirt is usually less expensive per ton but offers lower structural performance and can settle more, especially under vehicle traffic and in clay soils. Crushed rock or engineered base costs more up front but provides better compaction, drainage, and long-term stability; many Bay Area contractors recommend crushed base for driveways to avoid recurring maintenance.

Lead times depend on local supplier stock and truck availability; in the Bay Area expect standard delivery windows of 2 to 7 business days, with next-day possible for orders placed early and when suppliers have local stock.

Local contractors typically place fill-dirt in 4- to 6-inch lifts and compact each lift with a plate compactor or small drum roller, use geotextile to separate poor native soils, and install proper drainage (swales, French drains) to avoid saturation. They also proof-roll the subgrade, check utility locates before delivery, and may request staged deliveries to allow proper placement and compaction.
