Fill Dirt in Point Reyes Station, CA

Fill dirt is locally sourced material used to raise or fill low areas; it usually contains sand, fines, and small gravel and is screened to remove most organics. In Point Reyes Station it is commonly used to raise yard grades, build up low spots before landscaping, and create base layers under driveways when covered by proper base rock. Because of our coastal climate, buyers often use fill dirt followed by topsoil or crushed rock for final surfacing.

Delivered prices vary with source, access, and truck size, but expect roughly $30 to $70 per ton, or about $40 to $100 per cubic yard delivered in West Marin. Narrow driveways, onsite spreading, or short lead times can increase the price, so get a quote through our site to see a location-specific estimate.

To raise 1,000 sq ft by 4 inches you need about 12.35 cubic yards (1000 * 4/12 / 27). Using a typical loose fill density of 1.2 to 1.6 tons per cubic yard, that equals roughly 15 to 20 tons. We recommend ordering 10-15% extra to allow for settlement and compaction.

For structural driveway work, use engineered or clean compactible fill (screened, low organics) and combine it with a proper base rock (gravel or crushed rock) for stability and drainage. For general yard grading, screened fill dirt with a mix of fines is fine as long as it is free of roots and large organic material; finish with topsoil for planting. Avoid using loose, high-organic topsoil as primary fill beneath a driveway in Point Reyes Station due to moisture and settlement risk.

Marin County may require permits for large fills, grading, or projects that change drainage, and coastal zone properties may also need review by the California Coastal Commission. Smaller landscaping deliveries often do not need a county permit, but any import over a certain volume or work that affects wetlands, drainage, or slope stability should be checked with Marin County Planning and Building. When in doubt, contact the county before ordering to confirm regulations for your parcel.

Standard delivery is usually 2+ business days, with next-day options available when ordered before the cutoff (check our site for cutoff times). Local suppliers in Marin and nearby counties supply most material, but availability can shift seasonally and after heavy rain, so lead times may extend.

Most deliveries are made by tri-axle dump trucks, which commonly carry roughly 10 to 16 cubic yards depending on material and compaction; minimum orders generally start around 3 tons. Point Reyes Station has narrow, winding roads and some private lanes where a large truck may not access the yard; check driveway width, overhead clearance, culvert capacity, and local weight limits before ordering. If access is tight, note that in your order and our team can advise on offload locations or smaller trucks where available.

Compact fill in 4-8 inch lifts using a plate compactor for small areas or a vibratory roller for larger areas, and aim for around 90% of maximum dry density per Standard Proctor unless a project engineer specifies otherwise. On slopes and near structures, compaction and proper drainage become more important to prevent settling and sliding, so follow any engineer recommendations for lift thickness and moisture control. Always avoid placing saturated fill and schedule work in drier weather when possible in Point Reyes Station.

Fill dirt often contains fines that reduce permeability, so by itself it is not ideal for promoting drainage on slopes; you should combine it with engineered drainage layers, filter fabric, or rock where needed. For erosion control on coastal slopes, use terracing, drainage swales, erosion-control blankets, and native vegetation to stabilize new fill. In high-runoff areas typical of coastal Marin, proper surface water diversion and erosion measures are critical to long-term stability.

Fill dirt is generally not recommended as the primary cover for septic drainfields because fines and organics can clog the drain rock and soil interface; the typical specification is clean, coarse drain rock and native percolation-appropriate soil. Always follow county health department and septic design specifications for materials and cover depths in Marin County, and consult your septic designer before importing fill for a drainfield.

Lifespan depends on design, compaction, drainage, and surfacing: a well-built driveway with a compacted fill layer and proper base rock can last many years, while a drive built directly on uncompacted fill will settle and rut quickly. Raised beds using fill dirt as structural fill are fine if capped with quality topsoil for planting; expect some settling in the first year and plan to add soil or mulch. Regular maintenance like regrading, adding surface material, and maintaining drainage will extend performance in our coastal, wet winters.
