For Seattle and heavy clay, use angular crushed stone that locks together, such as 3/4u0022 crushed rock or crusher-run (3/4u0022 minus) as a base. Combine that with geotextile fabric and proper grading to separate the clay subgrade from the stone so the driveway stays stable in wet conditions. For a finished surface you can use smaller crushed fines or compacted gravel depending on whether you want a firm, driveable surface.

Yes—stone performs well in Seattle when installed with a drained base, proper slope, and edge restraint. Use angular crushed stone for stability and consider washed, open-graded stone where drainage is critical. Routine maintenance like raking and topping low spots after heavy rain will keep paths in good shape.

A typical 2-car driveway (about 20 ft by 20 ft) needs roughly 5 tons of stone at 3 inches depth and about 7 tons at 4 inches depth. Exact needs depend on your driveway size and desired depth; use Hello Gravel’s calculator or provide your dimensions for a precise estimate. Remember our minimum order is 3 tons.

Hello Gravel connects you to local suppliers and haulers across the Seattle-Tacoma area so you can compare delivered quotes quickly. Prices vary by stone type, quantity, and delivery details; as a rough baseline, delivered prices in the Puget Sound region often vary by material and market conditions. For an accurate per-ton or per-yard price for the exact stone you want, get a quote through Hello Gravel or contact nearby suppliers directly.

Both have roles: clean, washed stone or open-graded rock (no fines) gives the best drainage, while crushed rock with fines compacts better and is more durable under traffic. For Seattle yards use clean stone in drainage trenches and open areas where water must move freely, and use crushed, angular stone with some fines for driveable surfaces or areas that need compaction. Combining layers—drainage stone under a compacted base—often gives the best of both worlds.

A well-installed stone driveway can last a decade or more; lifespan depends on traffic, drainage, and maintenance. Expect to regrade and add a few inches of stone every 3-7 years in high-use areas and perform seasonal tasks like raking, filling low spots, and removing weeds. Keeping drains clear and managing surface runoff will extend the life of the material.

If the work stays entirely on private property and does not change the curb cut or public right-of-way, a permit is often not required. However, changes that alter access to the street, remove sidewalk, or affect stormwater flow may require permits from Seattle Department of Construction and Inspections (SDCI) or Seattle Public Utilities. Check with SDCI before starting and consult local code or Hello Gravel for guidance on permit thresholds.

Yes—permeable driveway systems using open-graded stone, geotextile, and an infiltration layer can meet Seattle stormwater and Low Impact Development (LID) goals when properly designed. Depending on your site you may need a specific design, underdrain, or detention element to meet city requirements. Before you build, review Seattle Public Utilities guidance or consult a local engineer to ensure the design complies with local stormwater rules.

For cost-effectiveness and reasonable drainage, crusher-run or crush-and-run (locally sourced 3/4u0022 minus) is a common choice for driveways and larger landscape areas because it compacts well and is widely available. If drainage is a higher priority, use a clean, washed drain rock in selected spots or combine a less expensive crusher-run base with a thinner layer of cleaner stone on top. Recycling options like crushed concrete can also reduce cost but check local availability and material suitability for drainage.
