Fill Dirt in Solano County, CA

Delivered fill-dirt prices in Solano County vary with source, distance, and quality. Expect a rough range of about $20 to $45 per ton (approximately $15 to $35 per cubic yard) as a starting point, with Bay Area-adjacent hauling often toward the higher end. Densities and local fees affect final price, so request a Hello Gravel quote for an exact delivered cost to your zip code.

For basic yard grading use clean fill-dirt with low organic content and a well-graded mix of fines and coarser particles to minimize future settlement. For driveways, use structural or engineered fill and place a compacted aggregate base (crushed rock) under the wearing surface; standard garden/topsoil is not appropriate for structural driveway bottoms. For foundation or engineered pads, follow a geotechnical recommendation rather than standard fill-dirt.

Permit needs depend on volume, location, and whether the work changes drainage or is in a regulated area. Small, routine top-up fills often do not need permits, but grading permits, erosion control plans, and public works approvals may be required for larger fills, fills near creeks, or alterations that affect stormwater. Contact Solano County Development Services and Public Works with project details before ordering to confirm local permitting and erosion-control requirements.

Hello Gravel's minimum order is 3 tons. Deliveries in Solano County are commonly made by tri-axle dump trucks or end-dump trucks that carry roughly 10 to 14 cubic yards loose (truck capacity varies by local hauler). Standard delivery is scheduled 2+ business days out; delivery fees depend on distance, site access, and disposal/driveway restrictions, so check your quote for any additional charges.

Wet winters can increase settlement risk and cause surface runoff and erosion if fills are not compacted and stabilized, while hot, dry summers can lead to shrinkage and dust. Proper compaction, erosion control (silt fences, straw, hydroseed), and scheduling work outside heavy rains will reduce problems. Use well-graded, low-organic fill and follow contractor or geotechnical guidance for seasonal considerations.

Residential grading commonly targets about 90% to 95% relative compaction, with lifts typically 4 to 6 inches before compaction for granular fills. Small areas can be compacted with a plate compactor or jumping jack; larger areas usually require a vibratory roller or large plate compactor. Rental rates vary (plate compactor $70-$150/day, small roller $200-$800/day) and contractor compaction and testing costs for a typical driveway or yard can range from a few hundred to a few thousand dollars depending on size and testing requirements; for structural work, get a geotechnical spec and contractor bids.

Choose fill-dirt for non-structural tasks like raising low spots, backfilling, or rough grading where compaction and drainage are addressed. Use crushed rock or aggregate as a structural base for driveways and to improve drainage. For building pads, footings, or retaining walls you should use engineered fill placed and tested to a geotechnical specification rather than ordinary fill-dirt.

Calculate volume: multiply length x width x depth (feet) to get cubic feet, then divide by 27 to get cubic yards. Convert cubic yards to tons using a typical loose-fill conversion of about 1.0 to 1.3 tons per cubic yard (a common rule of thumb is roughly 1.1 tons/yd3 for general fill). Example: a 50 ft x 30 ft area raised 3 inches = 50 x 30 x 0.25 = 375 ft3 = 13.9 yd3, which is roughly 15 tons at 1.1 tons/yd3. Always order slightly extra (5-10%) for grading and settlement and confirm density with your supplier.

Yes. Placing fill near creeks, floodplains, or slopes can trigger county and state regulations, and may require permits, setbacks, or mitigation to protect channels and reduce flood risk. Check Solano County floodplain maps, contact the county Public Works and Development Services, and consult regional agencies before delivering material; improper fills can change drainage patterns and lead to enforcement actions or required restoration.

Drivers may be able to perform tailgate spreading at their discretion if you request it at checkout, but this service is not guaranteed and depends on truck type, site access, and safety. If you need defined spreading and grading, plan to hire a landscaper or contractor and note any spreading requests in your order Notes so the driver can assess on arrival.

Standard delivery is typically scheduled 2+ business days after ordering, while next-day delivery is sometimes available for orders placed before noon CST for an additional fee. You can choose your preferred delivery date during checkout and Hello Gravel will confirm the delivery window with the local hauler; site access, permits, and supplier availability can affect scheduling, so book early for time-sensitive projects.
