Why Foster City Homeowners Choose Hello Gravel
Foster City, West California, has a population of 26,495 and sits within a metro area of 2.5+ million. With a steady growth rate of 0.40% annually and a climate that averages 228 sunny days per year and an annual rainfall of 34.25 inches, homeowners and local builders need materials that handle both sun exposure and periodic wet seasons. Located in USDA hardiness zone 8b, the city’s soils and development patterns favor compactable, low-organic fill for reliable subgrades. As infill, landscaping, and small construction projects increase with urban growth, homeowners seek Fill Dirt that compacts well, reduces erosion, and creates a stable base for patios, raised beds, retaining walls, and foundation backfill.Popular Projects in Foster City This Season

Frequently Asked Questions - Foster City Fill Dirt Delivery
Everything you need to know about fill dirt delivery in Foster City.
In Foster City, delivered fill dirt prices in 2025 commonly range from about $30 to $70 per ton, or roughly $36 to $84 per cubic yard depending on local sourcing, moisture content, and delivery distance. Bay Area rates tend to be higher than inland California because of truck access and landfill disposal costs; exact pricing appears at checkout after you enter your zip code. Hello Gravel has a minimum order of 3 tons and shows final delivered pricing and any fees before you pay.
Standard delivery through Hello Gravel is typically 2 or more business days, and next-day delivery may be available for orders placed before noon CST for an extra fee. Local lead times in Foster City and San Mateo County can vary with supplier availability and weather, so check the delivery calendar at checkout or contact our team for tighter timelines. Remember the minimum order is 3 tons and deliveries are by local dump truck fleets.
Fill dirt can compact well in Foster City if it is free of organic material and placed in controlled lifts with proper compaction equipment; however, underlying Bay Area clay and legacy fill often drain poorly. For improved drainage, contractors commonly install a granular base or drainage layer under the fill, and slope finished grades away from buildings. Ask your contractor or Hello Gravel for material recommendations if you expect standing water or poor soils on site.
Permit requirements vary by project and Foster City typically requires permits for work that changes site drainage, alters grades significantly, adds more than a few feet of fill near structures, or affects public right-of-way. Before ordering large volumes or planning grading, contact Foster City Planning/Building to confirm thresholds and whether a grading permit, erosion control plan, or setback clearance is needed. Hello Gravel can help with delivery details but cannot determine permit status for your project.
For yard leveling, choose clean fill dirt with low organic content and some fines so it compacts uniformly; contractors may recommend a well-graded sandy-clay blend for stability. For driveways, use a structural approach: a compacted granular base or crushed rock for load-bearing capacity, with fill dirt only used to bring grades up before the base is installed. Always ask suppliers for 'clean fill' or 'structural fill' and consider a geotextile or base material for coastal Bay Area conditions.
To raise 1,000 sq ft by 1 inch you need about 3.1 cubic yards of fill (1000 * 1/12 / 27 = ~3.09). Because fill dirt typically weighs about 1.1 to 1.4 tons per cubic yard, that equals roughly 3.5 to 4.5 tons; we recommend ordering at least 10% extra to account for settling and compaction. Use Hello Gravel’s material calculator or call our team to get a precise estimate for your site.
Clean fill dirt is native soil without organic waste or construction debris and is preferred for structural fills and landscaping; recycled fill may include crushed concrete or mixed fill and can vary in consistency. California and local jurisdictions may restrict where recycled materials can be used, especially near sensitive areas or for structural applications, so verify material type and approvals with Foster City Building/Planning. If you need recycled materials, request material specs and testing documentation from your Hello Gravel supplier before buying.
Contractors typically place fill in 4- to 6-inch lifts and compact each lift with plate compactors for small areas or vibratory rollers for larger projects, aiming for roughly 90-95% of Standard Proctor density for structural work. For small yard fills a heavy plate compactor is common; for driveways or foundations, heavier rollers and testing by a soils engineer may be required. Discuss your compaction needs with your contractor and specify them in project or permit documents when necessary.
Yes. Foster City’s coastal climate means wet winters (rain and higher groundwater) can delay deliveries, make compaction harder, and increase settlement risk; summer and early fall are generally better for spreading and compacting. Tidal influences and a shallow water table in some areas may affect deep fills; check site drainage and schedule deliveries on dry days when possible. Hello Gravel suppliers will advise on seasonal constraints and can reschedule deliveries if weather prevents safe work.
For driveways in Foster City, crushed rock or a compacted aggregate base performs better under vehicle loads and for drainage than plain fill dirt; fill dirt can be used to set grade but not as the structural wearing surface. Crushed rock provides load-bearing strength and sheds water; combine it with proper compaction and drainage to prevent rutting. If cost is a concern, talk to a contractor about a layered approach: structural aggregate base topped with a thinner decorative gravel or paving material.
Hello Gravel can connect you with local suppliers who provide material descriptions and common specifications, but formal geotechnical testing or engineering recommendations should come from a soils engineer or testing lab. For permit-driven or structural projects in Foster City, plan to get compaction tests or a soils report to meet city requirements. Our team can help schedule deliveries to match contractor timelines once testing and approvals are complete.
Include clear drop location, site access details (gates, overhead wires), and any permit or private road restrictions in your order notes; mention if you’d like the driver to consider tailgate spreading as a courtesy (drivers may do this at their discretion). Confirm truck size and turning radius with Hello Gravel if you have tight access in Foster City neighborhoods, and make sure the driver can legally and safely dump on your property or in the public right-of-way if needed.
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.
