Hello Gravel partners with local suppliers and haulers who serve Suquamish; availability depends on your exact zip code and job access. Typical minimum order is 3 tons, and standard delivery on many orders is included, though remote sites, short-notice requests, or limited-access deliveries may incur extra trucking or mobilization fees.

First calculate cubic yards: area (sq ft) x depth (ft) / 27. For example, 1,000 sq ft raised 4 inches (0.333 ft) needs about 12.3 yd3 and 6 inches (0.5 ft) needs about 18.5 yd3. Convert to tons using a supplier density—fill-dirt commonly ranges about 1.2 to 1.6 tons per cubic yard loose (confirm with your supplier); using 1.4 tons/yd3, those volumes equal roughly 17 and 26 tons respectively.

Yes. If your project is near tidelands, shorelines, wetlands, or critical slopes in Kitsap County or tribal lands, you may need permits from Kitsap County Department of Community Development and possibly coordination with the Suquamish Tribe and the Washington State Department of Ecology. Always check with Kitsap County planning and the local permitting authority before importing fill, and include permit notes when ordering if approval is required.

Suquamish’s rainy climate increases settling and erosion risk; imported fill-dirt will likely settle during the first wet season and can wash if not stabilized. Proper compaction, drainage measures, erosion control (silt fencing, mulch, seed), and choosing the right material layer for the job will reduce settlement and washout in wet conditions.

Fill-dirt (fine mineral soil) is suitable for non-structural grade raising and landscaping. For driveways, use road base or crushed rock over a compacted fill layer; foundations and structural fills usually require engineered fill or compactable granular material specified by an engineer. For slope stabilization, angular crushed rock with geotextile and proper drainage is preferred over loose fill-dirt.

For non-structural landscape fills, compact in 6- to 8-inch lifts with a plate compactor or small roller to achieve consistent density. Structural fills under building foundations generally require engineering specs (often 90-95% Standard Proctor) and larger compaction equipment like vibratory rollers; consult a soils engineer for any load-bearing work in Suquamish’s wet soils.

Common alternatives are crushed rock, road base, and engineered structural fill. Crushed rock and road base cost more than plain fill-dirt but offer far better drainage and load-bearing performance for driveways and paths; engineered fill is the most expensive but required for foundations and structural work. In Suquamish’s wet climate, the improved durability of rock or engineered materials often offsets the higher upfront cost through reduced maintenance.

Possibly. Tri-axle dump trucks need room to turn and stable ground; very steep, narrow, or heavily vegetated lots may require smaller trucks, offloading by loader, or hand-spreading, and those options can add fees or change minimums. Add site access notes and photos at checkout or call our team so suppliers can quote accurate trucking options and any additional charges.

Expect some settling during the first rainy season; plan to regrade low spots and add a topping layer (1-3 inches) as needed in the first year. Long-term stability depends on drainage, compaction, and surface treatment—stabilize exposed fills with seed, mulch, gravel, or hard surfacing, and check slopes and edges after heavy rain for erosion.

You can request tailgate spreading or special instructions at checkout, and drivers may perform tailgate spreading at their discretion if conditions are safe. We coordinate with local haulers to accommodate requests, but spreading is not guaranteed; contact our team before delivery to discuss options and to add access notes or photos for the driver.
