Fill Dirt in Centennial, CA

Prices vary by supplier, haul distance, and order size, but delivered fill-dirt in the California region commonly runs about $12 to $40 per ton (roughly $16 to $53 per cubic yard) as a general estimate. Final price depends on local availability and truck routing; Hello Gravel requires a 3-ton minimum and can provide an exact delivered quote for your zip code.

One cubic yard equals 27 cubic feet, so it will cover about 324 sq ft at 1 inch depth, 162 sq ft at 2 inches, 108 sq ft at 3 inches, and 54 sq ft at 6 inches. Because fill-dirt weight varies by moisture and compaction, use cubic yards for coverage and add 10-20% extra for compaction and settling when ordering.

For SoCal conditions, use clean, low-organic fill-dirt or engineered structural fill with minimal clay and organics so it compacts well and sheds water. On slopes, combine compactible fill with a granular drainage layer (crushed rock or crusher-run), geotextile, and erosion controls (matting or vegetation) to reduce slumping and surface erosion.

Local rules vary, and permit requirements depend on volume, grading, slope changes, and whether the work affects drainage or structures. Contact your city or county building and planning department before ordering — permits are commonly required for large fills, retaining walls, or regrading that changes runoff; Hello Gravel can supply delivery and material documentation to support permit applications.

Common alternatives include crushed rock or crusher-run, recycled concrete base, and engineered fill; these options typically provide better drainage and load-bearing performance than loose fill-dirt. Per-ton costs can be similar or slightly higher than plain fill-dirt, but you often need less material and less future maintenance, making them cost-effective for driveways and structural bases.

Good quality fill-dirt with low organic content compacts well when placed in thin lifts; aim for 4 to 6 inch lifts and 6 to 10 passes with a plate compactor on each lift. For small residential areas use a walk-behind plate compactor or a small ramming compactor for tight spots; larger jobs may require a vibratory roller and professional compaction testing.

Once properly compacted and covered (pavement, gravel, or vegetation), fill-dirt requires minimal maintenance, but exposed slopes can erode during heavy rains and may need erosion controls or regrading after storms. In dry heat, vegetation establishment can be slower; using mulch, erosion blankets, or gravel surfacing helps protect exposed fill while plants take hold.

Homeowners buy fill-dirt from local quarries, landscaping yards, recycled-material yards, or via online marketplaces like Hello Gravel that connect you with local suppliers and truckers. Deliveries are typically by dump truck (tri-axle) with a 3-ton minimum through Hello Gravel; standard delivery is 2+ business days, with next-day delivery sometimes available for orders placed before noon CST.

Measure the length, width, and desired depth in feet, multiply to get cubic feet (L x W x D), then divide by 27 to convert to cubic yards. Add 10-20% for compaction and settling, and remember Hello Gravel's minimum order is 3 tons — use our online calculator or contact our team for help with conversions and final quantities.
