Fill Dirt in Clackamas Heights, OR

Typical delivered prices in West Oregon (Clackamas Heights area) vary by supplier and access, but expect roughly $25 to $60 per cubic yard for material plus delivery. Per-ton pricing is around $20 to $45, using a working conversion of about 1 cubic yard = 1.2 tons (actual weight depends on moisture and material). Final cost depends on volume, driveway access, haul distance, and whether small trucks or special handling are needed; Hello Gravel’s minimum order is 3 tons and you can get a site-specific quote on checkout.

In wet, clay-prone areas around Clackamas Heights, choose well-graded fill or a sandy loam fill-dirt that drains better and is less prone to long-term settling than pure clay. For structural fills or where drainage is critical, contractors often mix in clean sand or crushed rock layers and use engineered or structural fill specified by an engineer. Because local material varies, add a note in your Hello Gravel order if you prefer a sandier mix or better drainage properties.

Good practice is to place fill in loose lifts (typically 4 to 8 inches) and compact each lift with a plate compactor or vibratory roller until the required density is reached. For driveways and load-bearing areas contractors usually aim for 90-95% of standard proctor density and control moisture during compaction. For deep fills or near foundations, hire a geotechnical engineer to specify lift thickness, target compaction, and testing requirements.

Always grade new fill to shed water away from structures and toward safe discharge points; aim for at least 1/8 to 1/4 inch per foot slope away from foundations. Consider a granular base (crushed rock) under finish turf or pavement, install French drains or perforated pipe where groundwater collects, and use geotextile fabric on very soft spots. Proper drainage is especially important in West Oregon’s wet season to prevent saturation and settlement.

Use volume = area x depth. Examples: a 12' x 40' one-car driveway with a 4u0022 fill needs about 12 cubic yards ≈ 14 tons; a 1,000 sq ft yard raised 3u0022 needs about 9 cubic yards ≈ 11 tons; raising a 1/4-acre (10,890 sq ft) by 3u0022 requires about 1,212 cubic yards ≈ 1,450 tons. Measure your area and depth, then divide cubic feet by 27 to get cubic yards; multiply cubic yards by ~1.2 to estimate tons for ordering.

Permitting and testing depend on the fill volume, location, and proximity to streams, wetlands, or public rights-of-way; small landscaping fills often need no permit, while large fills, fills near water, or fills that change drainage usually trigger county review. For structural fills or fills supporting buildings you will likely need engineered recommendations and compaction testing. Contact Clackamas County Building and Development or your city planning office before large deliveries and consult a local engineer if the fill affects foundations, slopes, or septic systems.

Standard deliveries are by dump truck (typically tri-axle); ensure trucks can reach your drop point, that overhead wires and low branches are clear, and that steep or narrow drives may require smaller trucks or extra fees. Request tailgate spreading at checkout if you want the driver to help, but know spreading is at the driver’s discretion and not guaranteed.
