Gravel in Stinson Beach, CA

In the Stinson Beach area you can expect pea gravel, crushed rock, and decomposed granite to range roughly from $40 to $120 per ton depending on type and color. Coastal delivery and small-volume orders often increase per-ton cost, so prices on a per-ton basis are higher than inland metros. Request a quote for exact pricing and check minimums and delivery fees for your zip code.

Local landscape suppliers and regional aggregate haulers that serve Marin County typically deliver to Stinson Beach, often using tri-axle dump trucks. Expect a minimum order around 3 tons and additional delivery fees for steep driveways or small-lot access; some suppliers may include free delivery within nearby areas but charge for longer coastal runs. Use Hello Gravel to get local quotes and confirm exact delivery fees, minimums, and available delivery dates.

Salt spray and persistent fog can accelerate corrosion of metal edging and degrade finer binders, but they have minimal direct effect on natural stone aggregates. Angular crushed rock and well-graded decomposed granite perform better on slopes because they interlock and resist migration compared with smooth round pea gravel. For coastal exposure choose hard, dense rock (like granite or basalt) and avoid materials with high salt-prone fines or soft limestone.

As a rule of thumb, 1 cubic yard covers about 100 sq ft at 3 inches depth and weighs roughly 1.2 to 1.5 tons depending on rock type. For a 12-foot-wide driveway 50 feet long at 4 inches depth you would need about 6.7 cubic yards or roughly 8.5 to 10 tons. Steep sandy slopes often need a thicker compacted base and erosion control layers, so add 20-40% extra material compared with flat projects; use Hello Gravel’s calculator for a site-specific estimate.

Marin County and local homeowner associations may have rules about driveway appearance, dust control, drainage, and impermeable surface coverage, and Stinson Beach’s coastal zone can add permitting requirements. Before installation check with Marin County Planning and your HOA for setbacks, drainage rules, and any restrictions on material color or dust mitigation. If in doubt, request documentation or a permit check from your supplier or contractor.

Gravel is more permeable and easier to repair after erosion, which is useful on coastal, erosion-prone sites, but it requires more frequent maintenance and replenishment than asphalt or interlocking pavers. Asphalt gives a smoother, low-maintenance surface but can crack on shifting sandy slopes and is less permeable for drainage. Pavers offer durability and drainage options but are costlier to install and may need a well-engineered base to resist slope movement.

Combine a compacted base, geogrid reinforcement, and an angular, well-graded aggregate (or crusher fines) to stabilize gravel on slopes; geogrid reduces lateral migration while crusher fines or decomposed granite can lock together when compacted. Where runoff is heavy, add check terraces, edging, and properly sized drainage swales to reduce washout. For visual or high-traffic areas consider polymeric binders or stabilizing additives, but confirm coastal suitability and maintenance needs first.

Expect winter rains and occasional wind-driven sand to displace material, so plan for inspection and light replenishment every 1 to 3 years for walkways and annually or after major storms for driveways and slopes. Rake and regrade low spots, replenish lost material, and clear organic buildup to limit vegetative growth and drainage blockage. Good drainage planning before installation greatly reduces seasonal maintenance.

Because access to Stinson Beach can be narrow and steep, confirm truck access, drop location, and any on-site restrictions before ordering and expect a 3-ton minimum on most platforms. Add a little extra material to account for compaction and erosion, request delivery notes for tight access, and use local suppliers through Hello Gravel to compare quotes and delivery dates. Contact customer service early if you need tailgate spreading or special placement so the driver can assess feasibility on arrival.
