Why Lagunitas-Forest Knolls Homeowners Choose Hello Gravel
Lagunitas-Forest Knolls is a community of homeowners and small-scale builders within a larger West California region that counts 1.0+ million people in the city and 2.5+ million across the metro area. With a steady growth rate of 0.70% annually, steady development and renovation projects keep demand high for basic construction materials. The local climate—228 sunny days per year, 34.25 inches of annual rainfall, and a USDA hardiness zone of 8b—creates a need for materials that balance drainage and stability. Homeowners choosing aggregates want predictable performance for grading, foundation backfill, erosion control, and creating level terraces, so they look for fill dirt that compacts well and resists excessive settling under seasonal wetting and drying cycles.Popular Projects in Lagunitas-Forest Knolls This Season

Frequently Asked Questions - Lagunitas-Forest Knolls Fill Dirt Delivery
Everything you need to know about fill dirt delivery in Lagunitas-Forest Knolls.
Prices vary by supplier, truck access, and how far a hauler must travel; in the Lagunitas-Forest Knolls area delivered fill dirt commonly ranges roughly $25 to $60 per cubic yard (about $20 to $45 per ton). Hello Gravel requires a 3-ton minimum and offers quotes that include delivery, so check your zip code and request a firm estimate to see exact pricing for your driveway.
For steep sites around Lagunitas-Forest Knolls look for screened, low-organic fill that is well-graded (a mix of sand, silt, and some clay) so it compacts well and sheds water. For slopes or retaining areas combine compactable fill with proper drainage (French drains, swales), geotextile fabric, and a surface layer of crushed rock or mulch to reduce erosion; engineered fill may be required for critical grade work.
Compute volume: 50 ft x 12 ft x 0.5 ft = 300 cubic feet, which is about 11.1 cubic yards. Fill dirt in this area typically weighs about 1.2 to 1.4 tons per cubic yard, so you would need roughly 13 to 16 tons; order 10% to 20% extra for compaction and grading, so plan to buy about 12 to 14 cubic yards (about 16 to 19 tons).
Many Marin and Bay Area suppliers can deliver within a week, but availability depends on local stock, truck schedules, and access to your property in Lagunitas-Forest Knolls. Hello Gravel connects you with local haulers and shows delivery options during checkout; order early and note narrow roads or steep driveways so haulers can confirm serviceability.
Fill dirt will compact and hold basic grades, but in Marin's wet winters it can erode, settle, or become unstable if not properly compacted and drained. For lasting results add compaction in lifts, provide good surface drainage, and top with a drainage-capable layer (crushed rock) or use stabilization measures like geotextile fabric or engineered fill for areas with heavy rain or traffic.
If used only as a filler and not covered with a drained gravel surface, fill dirt may need regrading or topping every 1 to 5 years depending on traffic and rain exposure. For a durable driveway base in Marin County, compacted fill topped with 3 to 4 inches of crusher run or 3/4" minus rock will last much longer and require less frequent maintenance.
Fill dirt is cheaper for raising grade and filling low spots, but crushed rock or crusher-run is far more durable and drains better for the finished driving surface. A common cost-effective approach is to use fill dirt to build grade where needed and then cover it with a proper crushed-rock base and surface for long-term performance in Marin's climate.
Possibly. Marin County requires permits or grading approvals for some earth-moving, especially near creek corridors, steep slopes, or when significant volumes or grade changes are involved, and an erosion-control plan may be required during the rainy season. Contact Marin County Planning and Building or your local permitting office before large deliveries—Hello Gravel can deliver, but permit compliance is the customer's responsibility.
Septic systems typically require engineered, low-organic, well-graded fill that meets local health department specs and compaction tests; generic fill dirt is usually not acceptable unless tested and approved. Check with the Marin County Environmental Health Division and an engineer before using fill dirt for any septic or leach field work.
Common add-ons include distance-based delivery fees, small-load surcharges for orders under the minimum, fees for tight or steep access, and optional services like screening, compaction, or hauling away excess material. Tailgate spreading may be offered at the driver's discretion but is not guaranteed; request these services at checkout and get a detailed quote from Hello Gravel to see which fees apply to your address.
As of today, we require 2 business days for delivery.

We cannot get out of the truck and manually spread it. However, depending on the location, safety, and comfortability of the driver – we may be able to tailgate spread your material. This involves pulling the truck forward as material is being dumped to make it easier for you to distribute material after delivery.
The minimum order size is 3 tons.
