#57 Crushed Stone
Multi-use crushed stone for home & landscape projects. Ranging from ¾” to 1” in size, #57 stone is a versatile product used for concrete production, drainage applications, driveways, parking lots, and as base material under slabs and footings. Large enough to provide drainage but small enough to lock together when applied and create a stable base and a relatively smooth surface.
Drain Rock
A larger 1 ½” crushed gravel that allows for water flow and drainage, preventing accumulation and pooling when properly installed. Perfect for french drains and other drainage applications, around utility lines, septic systems, sump pump basins and drainage pits.
Road Base
(Class 5 | ABC | Crusher Run) A mixture of crushed limestone or granite, gravel, and sand, ranging from 1 ½” in size down to fines (small particles). Commonly used for constructing roads, driveway bases, parking lots, and other paved and unpaved surfaces. Intended to be compacted, hence the inclusion of fines within the material to provide support and be resistant to erosion and shifting.
3/4″ Crushed Stone
A reliable, clean ¾” crushed granite or limestone with many applications. Great for gravel driveways, concrete mixes, landscaping applications, and backfilling retaining walls or around foundations.
Compost
Premium compost packed with organic nutrients—perfect for revitalizing tired soil and supporting strong, healthy plant growth. Ideal for mixing into garden beds, raised beds, and landscapes needing a natural boost.
River Rock
Naturally rounded, decorative stone for landscaping, garden beds, and water features. Typically 1-2” in size, with options for larger sizes upon request. Comes in a variety of colors that vary based on location and natural stone availability, so please be sure to specify if you have color preferences.

Why Contra Costa County Homeowners Choose Hello Gravel
Contra Costa County serves a city population of 1.2+ million and sits inside a metro area population of 2.3+ million, a growing market that translates into steady demand for residential and infrastructure projects. A growth rate of 2.50% annually indicates ongoing building, infill, and landscaping activity — meaning homeowners increasingly need reliable access to bulk materials for patios, drainage solutions, garden beds, and foundation prep. With 228 sunny days per year and annual rainfall of 33.20 inches, local projects balance dry-season heat and winter rains; this combination shapes choices for drainage-capable aggregates, drought-tolerant soil mixes, UV-resistant surface products, and erosion-control blends. Quality bulk materials matter here because they perform across wet-dry cycles, reduce maintenance, and support both water-wise landscapes and durable hardscapes as the area develops. Contra Costa County’s climate and local weather patterns create specific performance needs for materials: extended sun exposure (228 sunny days/year) increases UV and heat stress, while 33.20 inches of yearly rainfall concentrates runoff into seasonal events that test drainage and erosion controls. In hardiness zone 8b, plants and landscape systems also benefit from materials that support moisture retention without compromising drainage. For homeowners, that means selecting well-graded aggregates, appropriately blended soils and mulches, and materials rated for repeated wet-dry cycles. Hello Gravel helps by connecting customers with local suppliers who source region-appropriate materials, offering scheduling and calculators to plan quantities, and providing guidance so material choices match Contra Costa County’s climate and development patterns.Popular Projects in Contra Costa County This Season

Frequently Asked Questions - Contra Costa County Gravel Delivery
Everything you need to know about gravel delivery in Contra Costa County.
Delivery costs depend on material type, quantity, distance from local suppliers, access difficulty, and any local permits or street restrictions. Hello Gravel has a 3-ton minimum and offers clear pricing and free delivery in many areas, but final cost is determined when you check your zip code and request a quote. For accurate pricing, get a quote that includes delivery fees, truck type, and any additional services.
Choose materials based on function: structural projects benefit from compactable base materials, while surface areas may use decorative, draining materials. For most projects you can mix and match from gravel, sand, dirt, stone depending on load needs, drainage, and appearance. Consider local climate and slope when choosing materials and ask our team for recommendations for both homeowners and contractors.
Measure the project area (length x width) and decide on a target depth to get volume, then convert cubic feet to cubic yards (27 cubic feet = 1 cubic yard). Material weight varies, so use Hello Gravel’s calculator or contact our team to convert cubic yards into tons for ordering. Round up slightly to allow for compaction and waste.
Contra Costa County has a Mediterranean climate with dry summers and wetter winters, so spring and fall are often best for major deliveries and installs when conditions are milder. Deliveries can be scheduled year-round, but wet or saturated ground in winter can restrict truck access and affect compaction. Plan ahead and allow extra time during rainy periods.
Permit needs vary by city and by the scope of work: driveway cuts, curb work, or structural changes often require permits, and large truck deliveries or on-street staging may need county or city approval. Check with your local city or Contra Costa County building and public works department, and consult Homeowner Associations if applicable. If you’re unsure, contact our team for guidance before ordering.
Most deliveries use tri-axle dump trucks that need sufficient turning radius, overhead clearance, and a stable surface to safely dump material. Local residential streets can have weight limits, narrow turns, or neighborhood rules that affect where trucks can park and offload. Tell us about access constraints when ordering so we can match an appropriate truck and plan the best drop location.
Many local suppliers and haulers offer better pricing for larger orders or repeat contractor accounts, and Hello Gravel connects you with suppliers that may have tiered rates. Request a volume quote through our platform or speak with our sales team for potential discounts on multi-load jobs. Pricing and discounts depend on supplier, lead time, and delivery logistics.
Clear a defined drop location, remove vehicles and obstructions, mark utilities and any underground lines, and check overhead clearance for trucks. Designate an on-site contact and confirm the preferred delivery date and window; drivers may offer tailgate spreading at their discretion but it is not guaranteed. Preparing the site reduces delays and helps ensure a safe, successful delivery.
Natural materials vary by regional sourcing, so color, texture, and consistency can differ from images or samples. If you have concerns, contact customer service promptly so we can review your order and work toward a resolution; refer to our policies for details on adjustments or returns. Providing photos and order details speeds up the process.
Standard delivery typically requires 2 or more business days, and next-day delivery is available for orders placed before noon CST for an extra fee. You will receive order confirmation and delivery scheduling information after checkout, but exact timing depends on supplier and local truck availability. We recommend ordering early for larger jobs and peak seasons to secure your preferred date.
As of today, we require 2 business days for delivery.

The material will be delivered via dump truck. If your order is under 20 tons, then it will likely be just one dump truck load. If your order is more than 20 tons, it will be more than one dump truck load.

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.
Hassle Free! Our goal is to make the buying process for gravel and other aggregates as easy and seamless as possible.

After the order is placed our in-house support team will contact you to confirm the details. We will send additional confirmations on the day before and the day of delivery.

No, because we are a national supplier, we utilize our existing network of suppliers across the country. Therefore, the materials will likely be delivered from a contracted trucking company.
