Hello Gravel connects you with local suppliers and contracted dump-truck fleets serving the Larkspur/Marin County area, so materials come from nearby quarries, pits, or engineered fill sources. Deliveries are usually made by tri-axle dump trucks; share site access details at checkout so we can match a supplier and truck that can safely deliver to your address.

Small backyard leveling or shallow garden fills often do not require permits, but any work that changes grading, alters drainage, involves significant volumes, affects creek setbacks, or supports structures may require a permit from the City of Larkspur or Marin County. When in doubt, contact your local planning or public works office before ordering and tell our team if your project involves grading, retaining walls, or slope work so we can advise on next steps.

Install fill in thin lifts (typically 4 to 6 inches) and compact each lift with the proper equipment (plate compactor for small areas, vibratory roller for larger fills) to avoid future settlement. Match moisture content to the material's optimum, avoid placing organic topsoil as structural fill, and for foundations or structural needs plan for compaction testing and engineer specs to achieve required density.

Conversion depends on soil type and moisture but a common rule of thumb is 1 cubic yard of loose fill dirt equals roughly 1.2 to 1.6 tons. For example, 10 cubic yards would be about 12 to 16 tons; use the higher end for wetter or denser clay-rich fills and the lower end for dry, friable material. If you give us your project dimensions, Hello Gravel can calculate an estimated tonnage for ordering.

Yes—adding fill changes slope and surface runoff, and in Larkspur's hilly, rainy environment that can increase erosion if not managed. Plan for drains, swales, terraces, or retaining walls as needed, avoid placing fill against creek setbacks, and consider erosion-control measures during the rainy season; check local regulations for work near waterways.

Before delivery, clear the dump spot and note driveway width, overhead wires, and neighborhood parking rules—many Larkspur streets and driveways are tight. Tell us about any weight limits or required permits for truck parking, request tailgate spreading at checkout if desired (driver discretion), and schedule deliveries for daytime when access is easiest.
