Fill Dirt in Colfax, CA

Fill dirt is soil used to raise ground levels or fill voids; it usually contains clay, silt, sand, and some small rock. In Colfax and the Sierra Foothills it is best for bulk grade changes, backfill behind walls, or under landscaping, but it is not a substitute for a structural base under driveways or concrete pads unless it is engineered and compacted. For structural work, ask for engineered fill or a granular base product and confirm compaction requirements with your contractor or local permitting office.

Delivered prices for fill dirt in the Colfax area typically vary by source and season, but expect a range roughly between $20 and $45 per ton (or about $25 to $60 per cubic yard). Final cost depends on distance to local quarries in Placer County, truck access, moisture content, and order size; request a zip-code based quote on Hello Gravel to get an exact delivered price. Remember Hello Gravel has a 3-ton minimum and standard delivery is usually 2+ business days.

There are multiple sand and gravel yards and regional quarries serving Placer County and nearby foothill communities that supply screened fill dirt and delivery. Hello Gravel connects you with trusted local suppliers and contracted dump-truck haulers in the Colfax area—enter your zip code to see available vendors and schedule delivery. If you need screened or engineered material, note that availability varies by supplier and you can add notes in checkout to request screening or special handling.

Permitting depends on the scope and location of your work; routine small landscaping fills often do not require a permit, but large fills, grading activities, or work within or near streams and wetlands can trigger Placer County grading permits and state water-quality permits. For any work close to waterways or that alters drainage, contact Placer County Building Services and the Regional Water Quality Control Board before you place material. If your project may require engineered fill or drainage changes, get a permit and engineered plans to avoid enforcement or remediation.

For driveways and structural pads, compacted engineered fill or a well-graded granular base (such as class II base or crusher run) performs better than general fill dirt because it offers strength and drainage. Screened fill dirt can be useful for leveling or landscape grade, but if you are building a driveway or slab, place fill dirt only below a designed structural base and follow compaction specs from an engineer or local contractor. In the Sierra Foothills, prioritize drainage and a stable granular layer above any clay-rich fill.

Colfax soils often include clay and loam that expand and shrink with wetting and drying, and seasonal winter rains can saturate poorly draining fill, leading to settlement or movement. To improve longevity, compact fill in lifts, provide positive surface drainage away from structures, and use a permeable granular layer where water infiltration and freeze-thaw cycles are a concern. If you suspect expansive clay, consider engineered solutions or testing before placing large volumes.

Residential contractors commonly compact fill to roughly 90% of the standard Proctor or as specified by an engineer, using 4- to 6-inch lifts. For small jobs, plate compactors and jumping jacks are typical; for larger fills or driveways, contractors use sheepsfoot rollers or vibratory rollers. Confirm the target compaction with your contractor and the county if your project requires a permit or engineered fill.

100 square feet raised 6 inches (0.5 feet) equals about 50 cubic feet, which is 1.85 cubic yards. Allowing 20-30% extra for compaction and settlement increases that to about 2.2 to 2.4 cubic yards, which typically weighs roughly 3.0 to 3.4 tons depending on moisture and soil type. That fits Hello Gravel's 3-ton minimum, but always request a calculation from your supplier and order a small buffer for settling.

Yes, some suppliers and haulers may charge extra for long driveway pulls, steep, narrow, or remote access, and operators will assess safety at delivery; seasonal road or weight restrictions may also apply during wet months. Note your access and any obstacles in the Order Notes during checkout so Hello Gravel can match a truck and driver that can safely deliver. Tailgate spreading is available at drivers' discretion but is not guaranteed.

Reputable suppliers typically provide a delivery ticket showing cubic yards or tons, delivery date, and supplier name, and can sometimes supply gradation or source information on request. For engineered projects, ask for compaction test reports and material gradation or certification before purchase; these are not standard for loose fill dirt unless you order engineered fill or a specific specification. If you need paperwork or testing, request it when you order through Hello Gravel so the supplier can confirm availability and any additional fees.
