No — fill dirt is intended for grading and building up low spots, not as a wearing surface for driveways. For a durable driveway that drains well on Portola Valley's hilly sites, use a compacted base of crushed rock or aggregate designed for driveways, with a proper wearing layer such as crushed rock or decomposed granite. If you need help selecting material, our team can recommend suitable aggregates for local conditions.

Often yes — geotextile fabric helps prevent mixing of soft native soils and fill dirt and improves stability and drainage on sloped or clay-prone sites around Portola Valley. In many cases a crushed-rock base beneath fill dirt or gravel plus a fabric layer gives the best long-term performance. For steep slopes or poor soils, consider a geotechnical consultation to determine the right combination.

Use clean drain rock or crushed gravel for French drains — not fill dirt — because rock allows water to flow while dirt clogs the drain. Hello Gravel supplies drain rock, clean gravel, and other aggregates appropriate for French drains as well as fill dirt for grading. Ask for recommended sizes (commonly 1/2u0022 to 1 1/2u0022 clean rock) when you request a quote.

Approximate coverage: one cubic yard covers about 324 sq ft at 1u0022 depth, 162 sq ft at 2u0022, and 108 sq ft at 3u0022. A 50 lb bag of typical fill dirt is roughly 0.5 cubic feet (depending on moisture and density), so it covers about 6 sq ft at 1u0022 depth. For bulk landscaping in Portola Valley, ordering by the cubic yard is usually more cost-effective than many small bags.

Installed costs vary with site access, slope, required excavation, and material choice; Portola Valley's hilly lots can add labor and grading expense. As a very general guide, simple gravel driveway installs in the Bay Area often fall in a wide range depending on scope, so get a site-specific quote from local contractors and include Hello Gravel delivery costs in that estimate. We recommend sharing photos and measurements with our team so we can provide realistic delivered-material pricing to include in contractor bids.

Hello Gravel can deliver fill dirt and many aggregates to small residential jobs in Portola Valley; drivers may be able to perform limited tailgate spreading at their discretion if requested at checkout. We do not handle permitting or official grading plan changes — those are the customer's responsibility or the contractor's scope. If you need spreading beyond simple tailgate work, coordinate with your contractor and note any access constraints when you order.

Fill dirt is usually the least expensive per cubic yard for raising grade or filling holes, but it is not a durable finished surface and does not provide the erosion control, drainage, or finished look of decomposed granite or crushed rock. For a low-maintenance, durable yard surface in West California, compacted crushed rock or decomposed granite is typically a better value long term. Tell our team your goal (grading vs finished surface) and we will help you choose the most cost-effective material.

You can in some simple cases, but for long-lasting results you usually need to prepare the area: remove vegetation, regrade, add a compacted base layer, and possibly geotextile fabric to prevent mixing and rutting. Portola Valley's soils and slopes make proper base work and compaction especially important to avoid settling and drainage problems. When in doubt, plan for basic prep work and ask us for material and delivery recommendations for your specific site.
