Gravel in Bolinas, CA

Material prices vary by type, but expect basic crushed gravel or road base to cost roughly $30 to $80 per ton. Delivered cost to Bolinas can run higher because of limited local supply and narrow coastal roads; typical delivered prices are often $60 to $150 per ton depending on access, type, and whether extra fees apply.

Crushed rock (3/4u0022 minus), crushed rock road base, and stabilized decomposed granite are commonly best for coastal driveways because they compact well and shed water. Avoid loose rounded pea gravel on driveways unless you use stabilizers or grids, since it migrates on slopes and with vehicle traffic. Ask for materials locally sourced for West Marin to match local drainage and aesthetic needs.

A typical 2-car driveway (about 18-20 ft by 20-22 ft) at a 3u0022 top layer requires roughly 4.5 to 6.5 tons of loose gravel. On sandy coastal soils you should plan a thicker, well-compacted base (4u0022 to 6u0022) and possible geotextile or stabilization, which increases the total to about 6 to 10 tons. Use our material calculator or contact us for a precise estimate based on your exact dimensions and chosen depth.

Expect routine maintenance like raking or dragging to redistribute material, topping up loose gravel every 1 to 5 years depending on traffic, and clearing sand or debris after storms. Coastal exposure can bring salt spray and windblown sand that increases wear and causes more frequent top-ups. For best results, consider edging, drainage controls, and occasional regrading to prevent low spots and erosion.

Gravel is lower cost up front, permeable, and easier to install or change, but it needs more ongoing upkeep and can move on slopes. Asphalt offers a smoother, low-maintenance surface but reduces permeability and costs more up front. Permeable pavers give a durable, stormwater-friendly option but carry higher material and installation costs; choose based on budget, maintenance tolerance, and local drainage priorities.

Yes, both washed gravel and crushed rock are commonly available, but local supply can vary because West Marin has few quarries. Suppliers often source from nearby counties, which can affect color, texture, and delivery cost.

Gravel is permeable and helps with surface drainage, reducing runoff if installed with proper base layers and grading. However, on steep coastal slopes gravel can migrate or wash out during heavy rains or storms unless you add erosion control measures like geotextiles, terracing, edging, or vegetation. For sloped sites, consider stabilization systems and consult a local contractor familiar with West Marin rainfall patterns.

Yes, stabilized gravel systems are often recommended for Bolinas, especially on driveways, sloped areas, or where sand and windblown materials are common. Gravel grids, resin binders, or polymer-stabilized mixes reduce migration, improve load-bearing, and lower long-term maintenance. Request stabilized options at checkout and discuss suitability with our team based on your specific site conditions.

Bolinas is in unincorporated Marin County, and specific rules may vary by parcel, neighborhood, or HOA; setback, curb-cut, and stormwater requirements are common considerations. Before large installations, check with Marin County planning or your HOA and confirm any permits needed for driveway changes or large deliveries. If you need help, our sales team can point you toward local resources to check regulations.

Lifespan varies: pea gravel often needs replenishing every 1 to 3 years under traffic, crushed rock and road base typically last 5 to 15 years with periodic top-ups, and compacted decomposed granite can last 5 to 10 years depending on use. Coastal factors like salt spray, windblown sand, and heavy winter rains can accelerate wear, so plan for more frequent maintenance than in inland areas. Choosing stabilized materials and good drainage will extend service life.

Yes. Bolinas has narrow, winding roads and some steep driveways that can limit truck access and require smaller dump trucks or additional handling fees. Note our minimum order is 3 tons, and drivers may assess tailgate spreading at delivery but cannot guarantee it; include site access notes at checkout to help us match the right truck. If access is restricted, we can advise on drop locations, smaller deliveries, or offload options to minimize extra charges.
