Decorative Stone & Rock in Ontario, CA

Common options in the Ontario / Riverside-San Bernardino area include pea gravel, river rock, crushed granite, 3/4u0022 to 1u0022 crushed stone, lava rock, and larger accent boulders. Typical price ranges (estimates) are about $40-$120 per ton for common gravels and crushed stone, $60-$150+ per ton for specialty or colored rock, and higher for large boulders by the ton; per-cubic-yard pricing roughly corresponds (about 1.3-1.5 tons per yard). Regional sourcing, color, and stone size affect price, so check availability and exact quotes by zip code.

Hello Gravel generally requires a 3-ton minimum order; many local suppliers and routes in the Inland Empire offer free or low-cost delivery on orders at or above that minimum. Delivery fees for smaller or specialty orders, long haul distances, or constrained access can range from a small flat fee up to $100-$200; standard delivery is 2+ business days and next-day delivery is available for orders placed before noon CST with an extra fee. Trucks are typically tri-axle dumps, so staging and driveway access can affect fees and where the material is dropped.

For hot, dry conditions choose stones that resist breaking down, drain well, and reflect or moderate heat depending on your needs. Light-colored gravels (limestone, lighter river rock) reflect heat and stay cooler, while crushed granite and lava rock offer good drainage and long life for xeriscapes; pea gravel and crushed decomposed granite are popular for paths and beds but may need more maintenance. Avoid fine sands that can compact and retain heat; always consider color, local availability, and the specific use (path, bed, or driveway).

Installation costs vary by scope: simple top-dressing of garden beds or pathways can be $2-$6 per sq ft (material plus basic labor), while full driveway installations that include base prep, compaction, and a 3-4u0022 gravel surface commonly run $5-$15 per sq ft. Add costs for weed barrier, edging, grading, and drainage work—weed fabric typically adds $0.50-$1.50 per sq ft and base prep depends on access and existing conditions. Always get local quotes because site access, hauling distances, and permit needs change final pricing.

City of Ontario and many local HOAs often encourage drought-tolerant landscaping but rules vary by neighborhood and association. Some HOAs have design guidelines that specify acceptable colors, rock sizes, or require a mix of plantings and prohibit bare rock expanses; the city may have stormwater and permeable-surface rules to consider. Before ordering, check your HOA CC&Rs and contact Ontario planning or your HOA for any front-yard, driveway, or visible landscape restrictions.

Measure the area in square feet, multiply by the desired depth in feet, then divide by 27 to get cubic yards (area * depth / 27 = cubic yards). To convert to tons, multiply cubic yards by a conversion factor between about 1.3 and 1.5 tons per cubic yard depending on rock density (e.g., 2,400-3,000 lb/yd3). Example: a 20x12 ft driveway at 3u0022 deep is 240 sq ft * 0.25 ft / 27 = ~2.22 yd3, or roughly 2.9-3.3 tons—this normally meets Hello Gravel's 3-ton minimum.

Decorative stone can last decades with low maintenance: occasional raking to redistribute stones, periodic topping up (a thin layer every 3-10 years depending on traffic), and spot weeding or herbicide treatments as needed. In Ontario expect some fines or dust accumulation from heat and wind; a quick rinse after dusty intervals and pruning to reduce debris helps. Replace or add material where settling or washouts occur, and inspect drainage after heavy storms to prevent erosion.

Decorative crushed stone and gravel is usually less expensive up front than pavers and provides excellent drainage; it requires less initial labor than paving but may need occasional topping and more ongoing maintenance. Decomposed granite gives a compact, natural look good for paths and some driveways but can wash out and requires re-compaction and stabilizers for vehicle traffic. Pavers cost more to install but offer long-term durability, defined edges, and lower maintenance; choose based on budget, desired look, and expected traffic.

Hello Gravel connects you to trusted local suppliers and haulers in the Inland Empire, so the fastest way is to enter your zip code on our site to see available materials and delivery options. You can also request samples, confirm truck types (tri-axle), and ask about regional quarries that supply your material to compare color and texture. For big or specialty orders, ask suppliers about quarry source, stock photos, and estimated lead times before you confirm.

Plan deliveries for dry, milder days—Southern California's summer heat can increase dust and make onsite handling harder, while rare heavy rains can wash fines and unsettle freshly placed material. Wildfire ash is a local concern; if ash is present, clean the area before spreading new stone to avoid discoloration and contaminant buildup. Also consider wildfire defensible-space rules: keep combustible mulches away from foundations and use noncombustible decorative rock in required zones if applicable.
