Fill Dirt in Coronado, CA

Hello Gravel requires a 3-ton minimum order. Many suppliers offer free delivery nearby, but Coronado deliveries can carry additional access or fuel fees because of island access, narrow streets, or limited offloading space; expect $0 to about $150 extra depending on supplier and site conditions.

Prices vary by supplier and moisture content, but a reasonable ballpark for Southern California fill dirt is about $10 to $30 per ton (roughly $12 to $40 per cubic yard) depending on quality and delivery distance. Exact pricing for Coronado will depend on local supply, trucking access, and any additional fees; request a quote for your zip code to see current rates.

For general grade-building in Coronado, screened fill dirt (fines removed) is usually best for easy compaction and grading. Crushed or angular materials provide better interlock and drainage for areas that will support pavement or heavy loads; use crushed base or compactable aggregate under driveways and use fill dirt only to raise grade or fill voids. If in doubt, use fill dirt for bulk raising and a crushed aggregate base for any driveway or structural area.

Permit rules vary by project scope and whether drainage, setbacks, or coastal regulations are affected. Small landscaping fills often do not need import permits, but any grading that changes drainage, adds significant elevation, or is near the shoreline or public right-of-way may require a permit from the City of Coronado or San Diego County. Check with Coronado Building & Planning before ordering large volumes or doing major regrades.

A practical rule: one cubic yard of loose fill dirt generally weighs about 1.2 to 1.5 tons, depending on moisture and composition. To estimate volume: cubic yards = (square feet x depth in inches) / 324; then multiply cubic yards by 1.3 (tons per cubic yard) for a quick tonnage estimate. Example: a 1,000 sq ft area at 6 inches depth needs about 18.5 yd3, roughly 24 tons of fill dirt.

Salt air does not directly change fill dirt, but coastal moisture and winter rains increase erosion risk and make compaction harder if material is wet. Protect regrades with proper drainage, slope stabilization, and turf or mulch cover; keep heavy compaction and base work to drier days to achieve stable results. For seaside properties, add a well-designed drainage plan to keep water away from finished fills.

Hello Gravel connects Coronado customers with trusted local suppliers and hauling fleets across the San Diego metro. There are contractors and landscapers in greater San Diego who routinely deliver and compact fill dirt for island properties; request a supplier and contractor quote through our platform to see local availability and to arrange compaction services if needed.

Place fill in thin lifts (4 to 6 inches) and compact each lift with a plate compactor or small roller to achieve stable fill. Use geotextile fabric, erosion control blankets, and terracing or retaining walls on slopes; install positive drainage (swales or French drains) above and below the slope to carry runoff away. Consider consulting a civil engineer for steep slopes or fills near property lines to ensure safe grades and proper compaction specs.

Fill dirt is primarily used to raise grade or fill voids and is not a wearing surface; it compacts well for subgrade but is not ideal for driveway surfaces. Crushed rock or decomposed granite are better for finished driveway or patio bases because they drain better and create a stable surface. Clean fill (free of organic material) is preferred where compaction and stability are critical; combine fill dirt for bulk raising with a crushed aggregate base for driveways.

Common measures include geotextile fabric under the fill to separate soil layers and geogrid reinforcement for heavy loads or weak subgrades. For surfaces that need a stable wearing course, use a compacted crushed aggregate base and consider polymer binders or a stabilized decomposed granite product for pedestrian areas. For structural or high-traffic areas, hire an engineer or contractor to specify cement or lime stabilization if needed.

Measure your area and use the material calculator to estimate yards and tons, and note access issues (narrow roads, overhead wires, and where the truck can dump) in Order Notes. Choose your delivery date, request tailgate spreading if desired (driver performs at their discretion), and call our team if you need help with quantities or compaction recommendations for Coronado conditions.
