Gravel in Solano County, CA

Typical retail prices in Solano County vary by type. Expect crushed base rock or crusher run around $30-$55 per ton ($23-$42 per cubic yard), decomposed granite around $40-$70 per ton ($31-$54 per cubic yard), and decorative river rock $60-$120 per ton ($46-$92 per cubic yard). These are approximate ranges; final price depends on local supplier, color, and delivery distance.

For Solano County's Mediterranean climate and clay soils, 3/4u0022-1u0022 crushed rock or crusher run (a mix of fines and stone) makes a durable driveway base, while compactable decomposed granite (DG) or crushed rock topped with 3/8u0022 minus helps with surface stability. Avoid loose pea gravel on steep areas because it migrates on clay and when wet; use angular, interlocking aggregates for better traction and compaction.

Hello Gravel requires a 3-ton minimum order and typically uses tri-axle dump trucks that carry about 10-14 tons. Standard delivery is 2+ business days, with a next-day option available if ordered before noon CST (additional fee applies). Delivery fees depend on supplier distance and access; many Solano County deliveries are free or low-cost within service areas, but remote or tight-access jobs may incur extra charges.

Permit requirements vary by city and by the unincorporated county. Many cities (for example, Vallejo, Fairfield, Vacaville, Benicia) require an encroachment or driveway permit for changes to a paved curb cut or public right-of-way and may require grading or stormwater controls for larger jobs. Check with your city public works or Solano County Planning Division before starting work to confirm local rules and any setback, grading, or drainage requirements.

A typical durable gravel driveway uses 4u0022-6u0022 of compacted base rock (crusher run or road base) topped with 2u0022-3u0022 of wearing aggregate. Compact the base in 2u0022 lifts with a plate compactor to achieve good interlock and support. Use sturdy edging such as steel, concrete curbs, treated timber, or paving stones to retain material and reduce migration, and add perimeter drainage where clay soils hold water.

Use the formula: (area in sq ft x depth in ft) / 27 = cubic yards, then multiply by about 1.3 to convert cubic yards to tons (typical crushed stone). Examples: a 2-car driveway (20'x40') at 6u0022 depth needs about 14.8 cu yd (≈19 tons); a 500 sq ft patio at 3u0022 depth needs about 4.6 cu yd (≈6 tons); a 100 ft drainage swale 1 ft wide and 6u0022 deep needs about 1.9 cu yd (≈2.5 tons). These are estimates; order slightly extra for compaction and spillage.

Gravel driveways can last many years with regular maintenance; expect to regrade or add a fresh topping every 3-7 years depending on traffic, drainage, and freeze-thaw cycles. Typical contractor costs for regrading and light replenishing run from a few hundred to a couple thousand dollars depending on driveway size; material-only topping is priced per ton plus delivery. Budget for occasional weed control, grading after heavy rains, and spot compaction to extend service life.

Because Solano County gets wet winters and has clay subsoils in many areas, prioritize good subgrade prep, geotextile fabric, and a well-compacted base to prevent rutting. Install swales, French drains, check dams, or rock-lined channels to control runoff on slopes, and consider terracing or retaining edges on steeper grades. Avoid placing unconsolidated gravel on steep, unprotected slopes where erosion or washout is likely during heavy winter storms.

Gravel has the lowest upfront cost and is easy to repair, making it attractive for rural properties, but it requires more periodic maintenance and regrading than asphalt or concrete. Asphalt provides a smooth, mid-cost surface with periodic sealing and overlays; concrete has higher upfront cost and long service life but can be more expensive to repair. Pavers offer aesthetic appeal and good drainage control but cost more to install; choose based on budget, traffic, and maintenance tolerance.
