Fill-dirt in North Bend, WA

Fill-dirt is a basic soil/aggregate mix used to raise ground levels, build up low spots, and backfill trenches or retaining walls. In North Bend it is commonly used for site grading, leveling building pads, and creating driveway subgrade where structural strength is not the primary requirement. Because local materials vary, expect regional color and texture differences tied to King County geology.

Prices fluctuate with supply, haul distance, and season, so the most accurate price is a live quote from Hello Gravel. As a general guideline, delivered fill-dirt in King County often falls roughly between $20 and $45 per ton (about $27 to $60 per cubic yard) depending on volume and access; contact us for an up-to-date delivered price to your zip code.

Hello Gravel partners with local King County suppliers and haulers that service North Bend and the Snoqualmie Valley. Minimums vary by supplier but Hello Gravel's platform has a typical minimum order of 3 tons; larger suppliers or remote deliveries may require higher minimums — check the supplier details in checkout or call our team for specific providers and quantities.

Fill-dirt weight depends on composition and moisture, but a practical range for West Washington mixes is about 1.2 to 1.6 tons per cubic yard. Wet, clay-rich mixes will be at the higher end of the range, while drier, sandier fills fall toward the lower end. Use a range when ordering and our material calculator for a more precise estimate.

A 12x40 area is 480 sq ft. For 4u0022 depth you'll need about 5.9 cubic yards (roughly 7 to 9 tons), for 6u0022 about 8.9 cubic yards (about 11 to 14 tons), and for 8u0022 about 11.9 cubic yards (about 14 to 19 tons), using a typical weight range of 1.2 to 1.6 tons per cubic yard. Order a small overage (5-10%) for compaction and settling, or use our online calculator for an exact quote.

Small driveway fills or minor grading often do not need a permit, but larger fills, building pads, or slope stabilization work can trigger King County permits and engineering requirements. Work near streams, wetlands, or steep slopes in the Snoqualmie Valley may be regulated; always check King County DPER or call our team before ordering large volumes so you can confirm permit needs and avoid rework.

For our wet climate, choose a well-draining, well-graded granular fill with limited high-plasticity clay content so water does not pond or cause long-term settlement. Aim for a mix with adequate coarse fraction for drainage and enough fines to compact (consult a soils or geotech spec if building a structural pad). Compaction to 90-95% relative density (standard proctor) and proper drainage layers are key in West Washington.

Fill-dirt is economical for non-structural grade adjustments but generally holds more moisture and drains slower than crushed rock. Crushed rock or rock base provides superior drainage and load-bearing capacity for driveways, while engineered fill is specified and tested for structural pads and retaining areas. For rainy North Bend conditions, crushed rock base with a thin fill-dirt top layer usually performs better than fill-dirt alone.

Deliveries are usually by tri-axle dump truck; Hello Gravel lists minimums (commonly 3 tons) and your checkout shows supplier-specific details. Extra fees may apply for short-loads, tight/steep access, long carries from truck to placement, street parking restrictions, or off-hours delivery. Drivers may offer tailgate spreading at their discretion; note that access and staging should be discussed at booking to avoid surprises.

A compacted fill-dirt surface used for low-traffic driveways may last several years but is more susceptible to rutting, ponding, and erosion in North Bend's rainy climate than rock-based bases. Regular maintenance such as grading low spots, adding fresh material, and fixing drainage will extend life; for long-term durability consider a crushed-rock subbase or engineered base for higher traffic or structural use.

On slopes use benches, erosion-control fabric, silt fences, and temporary mulch or erosion-control blankets to limit sediment runoff in heavy rains common to the Snoqualmie Valley. Stabilize final surfaces with native plantings or hydroseed and avoid placing large fills near streams or wetlands without permits. For significant slope work consult a geotechnical engineer and follow King County erosion and critical areas guidance.
