Fill Dirt delivery in Federal Way, WA

Delivered fill-dirt prices in Federal Way vary with supplier, haul distance, and order size, but expect a typical range of about $12 to $40 per ton (roughly $9 to $30 per cubic yard) for standard clean fill delivered to a residential site. Smaller orders or deliveries to difficult access sites may be at the higher end; always confirm minimums and delivery fees at checkout.

As a rule of thumb: raising 1,000 sq ft by 1 inch needs about 3 cubic yards; by 2 inches about 6 cubic yards. For a 10 ft x 50 ft driveway (500 sq ft) a 4-inch layer requires about 7.4 cubic yards. Convert cubic yards to tons using a local rule of thumb of about 1.1 to 1.3 tons per cubic yard for typical fill-dirt; check with your supplier for an exact figure.

In Federal Way’s climate it is best to use low-organic, well-graded fill or engineered structural fill rather than topsoil. For areas that need drainage or structural support, consider a sand/gravel or engineered fill mix that sheds water; avoid high-clay or high-organic fill unless it will be capped with proper base material and compacted. For structural pads or near foundations, get a geotechnical recommendation.

Small landscaping amounts usually do not need a permit, but significant grading, raising finished elevations, or work near critical areas can trigger City of Federal Way or King County permits. If your project changes drainage, affects setbacks, or alters more than a few cubic yards, contact the City of Federal Way Building Department or King County Permitting to confirm requirements before delivery. Always check before importing large volumes.

Proper installation means placing fill in controlled lifts (commonly 6 to 8 inches loose) and mechanically compacting each lift to specified density. For building pads contractors often aim for 90-95% of standard Proctor; driveway bases typically require a compacted structural base (road base or crusher run) below the final surface. Hire a local contractor or geotech for specs on structural work; Hello Gravel delivers material but does not guarantee compaction services.

Wet fall and winter conditions increase settling and can make sites muddy or inaccessible, which may delay deliveries or require additional site prep. For best results schedule deliveries in drier months (late spring through early fall) when possible, and allow extra time for settling if you place fill before heavy rains. Ask your supplier about holding or staging options if the ground is saturated.

Ask suppliers for a statement of source and any available soil testing showing low organics and absence of petroleum, heavy metals (like lead), or asbestos for sites with contamination risk. Common things to test for are organics, debris, hydrocarbon contamination, and heavy metals; request a “clean fill” affidavit or certificate of analysis when needed. If your property has a history of industrial use, consider lab testing before importing large volumes.

Use fill-dirt to raise grade or fill voids, but it is not a substitute for a structural driveway base. Crusher run or road base are graded, compactable materials designed to support vehicular loads and drainage; topsoil is for planting and should not be used under driving surfaces. A common approach is fill-dirt to set grade, then a compacted road-base layer for driveways, and topsoil only for planting areas.

Common add-ons include tailgate spreading (driver discretion), small-load or short-haul fees for tight-access jobs, compaction equipment rental or contractor fees, and rush/next-day delivery charges. Typical local ranges: tailgate spreading $40-$150 per load, compaction contractor or machine rental $100-$800 depending on scope, and next-day or priority delivery fees variable by supplier.
