For beachfront work, choose clean, low-organic 'select' or sandy fill with good drainage to reduce erosion and washout risk. Avoid high-clay or contaminated soils; for sites near bluffs or in erosion zones, engineered fill specified by a geotechnical engineer is often required.

Raising 1,000 sq ft by 4 inches requires about 12.3 cubic yards of material, which is roughly 16 to 18 tons of typical fill dirt. We recommend ordering about 15-25% extra to allow for compaction and grading, so plan on ordering around 20 tons and confirm with Hello Gravel’s calculator or sales team.

Fill dirt itself does not 'rust' from salt air, but salt can affect nearby plants, metal fixtures, and certain aggregate binders. Use clean, well-draining fill and cap it with appropriate topsoil or gravel and good drainage to protect plantings and reduce salt-related issues on coastal properties.

Fill dirt can be part of slope stabilization, but it must be properly compacted, graded, and paired with drainage controls, terraces, retaining walls, or erosion control measures. For steep or unstable hills common around Avila Beach, consult a geotechnical or civil engineer before major fills to ensure long-term stability and permit compliance.

If fill dirt is used as the subgrade and covered with a proper gravel or hard surface, it should be stable for many years, though settling can occur and low spots may need topping within 2 to 5 years depending on traffic and drainage. Using fill dirt as the wearing surface will deteriorate much faster, so we recommend a compacted aggregate surface over the fill for driveways.

Decomposed granite (DG) makes a firmer, attractive surface for coastal driveways, while fill dirt is intended to raise grades or build subbases. Typical approach: use fill dirt to set grade and compact the subgrade, then install DG or crushed rock as the wearing surface for better durability and resistance to washout.

Fill dirt alone is not a suitable base under pavers near the shoreline because it can wash out or settle. For pavers at or near the shore, use a compacted crush-and-run or crushed rock base, geotextile fabric, and edge restraints to prevent washout, with fill dirt used only to establish grade behind the engineered base.

You may need permits for importing fill or grading, especially in coastal zones or for work that changes drainage or impacts bluffs. Check with San Luis Obispo County Planning and Building, the county Public Works, and if your property is in the Coastal Zone, the California Coastal Commission or county coastal program to confirm permit requirements before ordering large volumes.
