Why Mill Valley Homeowners Choose Hello Gravel
Mill Valley, with a city population of 28,777 and located inside a growing West California metro of 2.5+ million residents, is seeing steady demand for home improvements and small-scale construction as it expands at about 0.80% annually. The area’s coastal slopes, mixed soils, and sunny climate make drainage, erosion control, and attractive hardscaping priorities for homeowners. Gravel is a common, practical choice for driveways, pathways, French drains, and erosion-prone beds because it is permeable, low-maintenance, and adaptable to sloped sites. For many DIY projects the right stone size and depth make the difference between a durable surface and one that compacts or washes out. Hello Gravel helps Mill Valley homeowners choose appropriate aggregate sizes, estimate quantities, and arrange local delivery so projects run smoothly without multiple trips to supply yards.Popular Projects in Mill Valley This Season

Frequently Asked Questions - Mill Valley gravel Delivery
Everything you need to know about gravel delivery in Mill Valley.
As a quick estimate, using local gravel density, 100 sq ft needs about 0.86 tons at 2", about 1.30 tons at 3", and about 1.73 tons at 4". Order 10-15% extra to allow for compaction, grading, and waste. Remember Hello Gravel's minimum order is 3 tons in most areas, so plan accordingly.
Delivery timing depends on supplier location; standard delivery is 2+ business days and next-day can be available for orders placed before noon CST with an extra fee. Delivery fees vary by distance, material type, and order size—smaller loads often have a higher per-ton cost. Use Hello Gravel's checkout to see transparent, location-specific pricing and note any access restrictions on your order.
For Mill Valley's steep, coastal-hills terrain, angular crushed rock (3/4" crushed rock or crush-and-run) and compacted decomposed granite (DG) that has been stabilized perform best because they lock together and resist movement. Avoid loose, rounded pea gravel on steep slopes because it can roll and become slippery when wet. Combine the right material with good base prep, edge restraint, and drainage for best performance.
Yes—driveway changes, work in the public right-of-way, or any grading may trigger City of Mill Valley or Marin County permits and stormwater controls. Marin County and the City enforce stormwater runoff rules and low-impact development practices, so check Mill Valley Public Works or Community Development and the county's stormwater program before you start. If in doubt, contact Hello Gravel or your local planner for guidance and verify permit needs.
Expect to do light maintenance annually—regrading ruts, reshaping the crown, and topping up material after heavy rains. More intensive repairs may be needed after major storms or several years of use; plan on adding fresh gravel every 2–5 years depending on traffic and slope. Good drainage, edge restraints, and periodic compaction reduce how often you need to regrade.
Many Mill Valley streets are narrow and hilly, which can limit access for tri-axle dump trucks typically used for deliveries. Note driveway width, overhead wires, tight turns, or weight-restricted roads in your order notes and during scheduling; drivers will assess access on arrival and may switch to smaller trucks where available (additional fees may apply). Contact Hello Gravel before ordering if access looks difficult so we can match an appropriate supplier and truck.
Use angular, compactable gravel and a well-draining base layer, plus geotextile fabric to separate soil from aggregate. Combine terraces, swales, check dams, or retaining walls and install positive drainage (culverts or French drains) to move water away from slopes. Planting native groundcovers and using edge restraint will also help hold material and reduce erosion.
Gravel is usually less expensive upfront than asphalt or concrete and provides much better infiltration, which helps manage stormwater on Mill Valley's hills. Gravel requires more ongoing maintenance and can erode on steep slopes if not properly engineered; it is noncombustible but vegetation nearby still affects wildfire risk. Asphalt and concrete are lower maintenance for traffic but increase runoff and usually cost more to install.
For pathways: 1/4" to 3/8" crushed gravel or decomposed granite over 2-3" of compacted base and a layer of geotextile is common. For driveways: excavate and compact native soil, install 4-8" of crush-and-run or 3/4" base rock compacted in lifts, then a 1-2" wearing course of fine crushed rock or stabilized DG. Always include edge restraints, proper slope, and drainage to prolong life on Mill Valley terrain.
Yes—Hello Gravel connects customers to local suppliers and can help you find landscaping contractors experienced with permeable gravel and paver installations in Marin County. Installation costs vary widely based on site prep, drainage work, and slope—expect a broad range (for budgeting) from a few dollars per sq ft for simple pathway work up to $6–$15+ per sq ft for engineered permeable driveways with drainage and retaining features. We recommend getting multiple quotes and asking contractors for references and examples of similar Mill Valley projects.

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.
