Why Millbrae Homeowners Choose Hello Gravel
Millbrae's city population of 21,120 and its steady growth rate of 0.70% annually make it a community where homeowners are often updating yards, driveways, and small-scale hardscape projects. With the West California metro area supporting 2.5+ million people, local development and renovation activity stays consistent. Millbrae's climate—about 228 sunny days per year and 34.68 inches of annual rainfall—plus its USDA hardiness zone 8b, creates conditions where materials need to balance drainage and low maintenance. Homeowners look for aggregates that control runoff, reduce erosion on slopes, and provide durable, attractive surfaces that withstand both sunny, dry spells and seasonal rains. Quality gravel saves time and money over the long run by reducing weeding, improving water management, and providing a stable base for pavers and walkways.Popular Projects in Millbrae This Season

Frequently Asked Questions - Millbrae gravel Delivery
Everything you need to know about gravel delivery in Millbrae.
Common sizes available locally include pea gravel (about 1/8" to 3/8") for decorative areas, #57 (roughly 1/2" to 1") for driveways and drainage, and #3 (about 1" to 2.5") for heavy drainage and base layers. Decomposed granite (fine, compactable) is often used for paths and patios. Suppliers in the Bay Area may offer additional mixes and local names, so check product details when ordering.
#57 gravel is typically angular stone around 1/2" to 1", with the common size being about 3/4". It is a good choice for driveways, walkways, and drainage trenches because it compacts reasonably well while allowing water to pass. For Millbrae’s mild coastal climate, #57 is a versatile, locally available option for many landscaping and driveway needs.
#3 gravel consists of larger stones, generally about 1" to 2.5" in diameter, so the texture is noticeably coarse and chunky. It is commonly used for major drainage lines, French drains, and as a base under large concrete slabs or roadways. Because of its size it does not compact into a smooth surface, so it is less common for finished walking areas.
One cubic yard equals 27 cubic feet and will cover about 108 sq ft at a 3" depth, about 162 sq ft at a 2" depth, or about 54 sq ft at a 6" depth. In weight, one cubic yard of typical crushed gravel in the Bay Area usually weighs around 1.3 to 1.5 tons, depending on stone type. Use these numbers to estimate how many yards or tons you need, or try Hello Gravel’s calculator for a site-specific estimate.
No, 2 inches is usually too thin for a driveway. For a stable vehicle surface most contractors recommend at least 3 to 4 inches of compacted gravel over a proper subbase, and 4 to 6 inches if the soil is soft or you expect heavy vehicles. Millbrae’s mild climate reduces freeze-thaw concerns, but proper depth and compaction are still important to prevent rutting and washouts.
Cost depends on driveway width, depth, gravel type, and delivery. For a single-car 20 ft long by 10 ft wide driveway (200 sq ft) at 3" depth you need about 1.9 cubic yards (roughly 2.5 to 3 tons). Expect materials and delivery to typically run from a few hundred dollars up to $700 or more depending on material choice and access — request a quote from Hello Gravel for an accurate price for your address and material.
Bank-run rock or recycled crushed concrete are often the least expensive options locally because they use locally sourced or recycled material. Decorative options like colored or washed pea gravel and premium crushed stone cost more. Prices vary by local supply and truck access, so check Hello Gravel for current regional pricing.
For decorative yards and seating areas pea gravel or small washed gravel (1/8" to 3/8") offers a clean look and comfortable surface. For pathways and driveways choose crushed 3/4" stone (#57) or compactable decomposed granite for a smoother, firmer finish. Consider Millbrae’s coastal weather and drainage needs when choosing: prefer materials that shed water and resist compaction where you expect foot or vehicle traffic.
Millbrae has a mild coastal climate with little freeze-thaw, so frost heave is rarely a concern, but coastal fog and salt exposure can affect some landscape plants and metal edging. Good drainage is still important because heavy winter rains can wash fine materials away and cause rutting. Choose angular crushed stone for stability, and consider edging, geotextile fabric, and proper slope to protect your gravel installation.
Order online or contact Hello Gravel to check zip code availability and get a quote. Our minimum order is 3 tons; deliveries are made by contracted dump trucks (typically tri-axle) with a standard lead time of 2+ business days and a next-day option for orders placed before noon CST. You can request tailgate spreading at checkout but drivers perform spreading at their discretion and Hello Gravel does not guarantee spreading services.
Contact Hello Gravel as soon as possible if you need to change or cancel an order. Changes are easier to accommodate before the supplier processes and dispatches the load, but modifications are not guaranteed after dispatch. If there is an issue on delivery, contact customer service and we will work to resolve it according to our policies.
Clear the drop zone of vehicles, low branches, and obstacles and mark any underground utilities or irrigation lines before the truck arrives. Ensure truck access from the street and designate the preferred dump location in your order notes; if placement is tight, consider flagging the spot for the driver. For smaller landscape areas, lay down a geotextile fabric and install edging to keep material contained after delivery.
As of today, we require 2 business days for delivery.

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.
