Fill Dirt in Clearlake, CA

Per-ton delivered cost for fill dirt in Clearlake commonly ranges based on distance, truck access, and material quality; expect roughly $12 to $35 per ton as a typical range. Hello Gravel has a 3-ton minimum order and many areas offer free delivery; exact pricing and delivery windows are shown when you enter your zip code at checkout.

For simple yard build-up and non-structural areas, ordinary fill dirt (native soils with some fines) is usually fine when topped with drainage rock for driveways. Foundations and any load-bearing work should use engineered or compacted 'structural' fill specified by an engineer; for erosion-prone slopes, use fill with good drainage, geotextile fabric, or a mix of fill and clean rock to prevent washout. Always confirm the grade with your contractor or local building inspector for structural work.

Clearlake sits near Clear Lake and many local soils contain clay and a relatively high water table, which can hold moisture and lead to slow drainage and settlement. That means fill dirt will compact differently and can stay wet longer after rain; plan for drainage (swales, French drains) and avoid relying on simple fill under structures without engineered preparation. Regional sourcing means material texture and color will vary, so expect local differences.

Residential projects commonly place fill in 4 to 6 inch lifts and compact each lift with a plate compactor or small roller until adequate density is achieved. Engineers often call for compaction to around 90-95% of maximum dry density for structural areas, but requirements vary by project so follow plans or consult a local soils engineer. Equipment access and moisture content can change how easily you reach compaction targets in Clearlake’s clay soils.

Convert area to square feet (1/4 acre = 10,890 sq ft), multiply by the desired depth in feet, then divide by 27 to get cubic yards. For example, raising 1/4 acre by 6 inches (0.5 ft) needs about 10,890 * 0.5 / 27 = ~202 cubic yards; depending on moisture and density that equals roughly 220 to 300 tons. Use Hello Gravel’s material calculator or contact our team for a precise estimate for your project and local material density assumptions.

Large grading, changes in finished elevation, or work near waterways often requires permits from the City of Clearlake or Lake County and may trigger erosion-control requirements. There are also truck weight limits and local road restrictions that can affect delivery times and routing. Check with the City of Clearlake building or public works department before large deliveries, and tell Hello Gravel about access or permit needs when ordering.

Alternatives include topsoil (good for planting but compresses more), clean fill or crushed rock (better drainage and load-bearing), and engineered fill or compacted structural fill (best for foundations). In Clearlake’s clay-prone environment, crushed rock or engineered fill costs more but reduces settlement and drainage problems compared with ordinary fill dirt, which is cheaper but may need more drainage work and maintenance. Choose based on budget, final use, and whether loads or structures are involved.

Yes — Hello Gravel’s platform connects you with local suppliers and haulers that serve Clearlake and the West California region; enter your zip code to see available materials and delivery options. For compaction, grading, or permitting help we recommend hiring a local contractor or soils engineer; Hello Gravel can help schedule delivery to work with your contractor’s timeline.

Expect some settling during the first rainy season; light regrading and adding a few inches of material is common within the first year. After initial settlement, driveways with a proper gravel surface generally need occasional regrading and top-up every 2 to 5 years depending on traffic and storms, while slopes need periodic inspection after heavy rains. Proper drainage and vegetation reduce maintenance needs.

Avoid placing loose fill directly downslope toward the lake; install silt fences, straw wattles, or temporary detention and revegetate exposed areas quickly to prevent sediment runoff. Follow local erosion-control rules and consider adding riprap, terracing, or native planting for long-term slope stability. If your project is close to waterways, check with Lake County and regional water quality authorities for any required permits or best-practice guidelines.

Provide clear access and a preferred drop location when ordering — tri-axle dump trucks are common and need room to maneuver and offload. Request tailgate spreading at checkout if you want driver help but know this is at the driver’s discretion; plan to hire a small loader or raker for final spreading and compaction. Let the Hello Gravel team know about narrow drives, overhead wires, or permit requirements so we can coordinate the right truck and timing.
