Gravel in Vashon, WA

Expect a wider price range than mainland deliveries because Vashon Island adds ferry or barge logistics. Typical delivered gravel rates vary by material and order size, and many suppliers add an island surcharge that often runs from about $100 to $400 per truckload; for small orders the per-ton delivered price can be noticeably higher. The exact cost depends on the supplier, truck size, where on the island the pile will go, and scheduling; get a quote for your zip code through Hello Gravel to see current local rates.

For driveways, angular crushed rock (for example 3/4u0022 crushed) or a crusher-run base with fines gives the best compaction and traction in wet weather. For walkways and decorative areas, washed pea gravel or 3/8u0022 decorative rock looks nice and drains well on flat areas, but pea gravel can migrate and is slippery on slopes. Washed drain rock (larger, clean stone) is useful for drainage trenches and keeping water away from structures.

Use a depth-based rule of thumb: one ton of gravel is roughly 0.74 cubic yards (about 20 cubic feet). That means one ton covers about 120 sq ft at 2u0022 depth, about 80 sq ft at 3u0022 depth, and about 60 sq ft at 4u0022 depth. For a compacted driveway finish you’ll commonly plan 3u0022 of finish stone over a compacted base, so estimate about 1 ton per 80 sq ft and remember Hello Gravel has a 3-ton minimum order.

Many contractors on Vashon favor a layered approach: use a compactable base such as crusher-run (which contains fines) for slope stability, then a washed or decorative top layer for appearance and drainage. Fines help lock the base together and resist migration, but too many fines in the top layer can reduce permeability and cause puddling. Combine fines with good grading, geotextile, and edge restraints to control erosion on slopes.

A few effective measures are geotextile fabric under the gravel to reduce mixing with native soil, sturdy edging or curbs to stop migration, and properly sloped swales or catch basins to move runoff safely. For steeper runs, use terracing, check-dams, or vegetation to slow water; retaining walls or gabions may be needed for severe erosion. Because Vashon soils can be silty, plan for good subgrade prep and outlet points for stormwater rather than relying on gravel alone.

Yes, suppliers around Puget Sound offer different blends and finishes, and material availability often reflects local geology. Many mainland suppliers deliver to Vashon but commonly add an island delivery fee for ferry/barge transport, limited truck windows, or staging; the fee varies by supplier and load size. Hello Gravel can check local supplier options for your zip code and include any island-related charges in your quote.

Gravel has the lowest initial cost and excellent permeability, which helps with stormwater on rainy Vashon, but it requires more regular upkeep like regrading and infill. Asphalt has higher upfront cost and creates an impervious surface that may need drainage management, but it typically needs less frequent attention than gravel. Permeable pavers cost the most up front, handle stormwater well, and require less frequent large-scale maintenance, making them attractive where runoff control and aesthetics matter.

Vashon is in unincorporated King County, so check King County zoning and stormwater rules for your parcel, especially if your work changes drainage patterns or removes vegetation. Also review any HOA covenants or CC&R restrictions that may limit surface materials, color, or total impervious area. When in doubt, contact King County and your HOA, and ask Hello Gravel for guidance before you order.

Light regrading is commonly needed every 1 year after heavy winter storms, while small top-ups of decorative or driveway stone are often needed every 2 to 5 years. Areas with concentrated runoff or steep slopes may require repairs or added material after major storms, and moss can appear in shaded, damp spots requiring occasional cleaning or replacement of the top layer. Regular maintenance like raking, spot replenishing, and keeping drainage clear will lengthen intervals between larger refills.

A correctly built, compacted crushed gravel driveway can function well for 10 to 20 years before a major rebuild is needed, though periodic maintenance is required. Annual upkeep costs for grading, minor pothole repair, and occasional topping typically run from about $50 to $500 depending on driveway size, condition, and whether island delivery is needed for material. Investing in a stable base, good drainage, and edging up front will reduce long-term maintenance on Vashon’s rainy slopes.
