For steep, hilly driveways in Blackhawk use angular, crushed stone with some fines (often called 3/4u0022 minus or crusher-run) because the particles lock together and resist sliding. A compacted base layer of larger crushed rock with a top wearing layer of smaller crushed stone improves traction. Consider a geotextile fabric under the base to reduce rutting on steep slopes.

A typical 2-car driveway around 20' by 20' is about 400 sq ft; at 3u0022 depth that equals roughly 3.7 cubic yards (about 5.2 tons) and at 4u0022 depth about 4.9 cubic yards (about 6.9 tons). Most homeowners in Blackhawk order between 5 and 7 tons for a 2-car driveway depending on depth and compaction. Remember our minimum order is 3 tons, so check your exact dimensions and depth before ordering.

Both have good uses in West California's dry climate: decomposed granite (DG) compacts to a smooth, low-water surface that is excellent for pathways and low-maintenance garden beds. Crushed gravel is better where drainage, vehicle traffic, or erosion control matter because it resists washing out and provides better load-bearing. Choose DG for formal paths and low traffic, and crushed gravel for driveways, drainage swales, and areas that need more stability.

Gravel holds up well in hot, dry summers without breaking down like some organic mulches, but color may fade and finer dust can loosen over time. Expect seasonal maintenance like raking, regrading low spots, and adding a 1/2u0022 to 1u0022 top-up of new gravel every few years depending on use. Use edging, good drainage design, and occasional compaction to reduce migration and dust.

Professional installation costs depend on site prep, grading, base rock, drainage work, and the material chosen; a rough range for installed gravel is about $2 to $6 per square foot. For a standard 400 sq ft 2-car driveway that means roughly $800 to $2,400, though prices can rise if slopes, retaining work, or permit-related work are needed. Get local contractor bids and factor in potential extra costs for erosion control on steep Blackhawk lots.

Yes, gravel is commonly used to improve drainage on sloped lots by creating infiltration zones and channeling water away from structures. Use clean drainage rock (1u0022 to 2u0022 clean stone) in trenches and as a base for French drains, and use crushed rock with fines on the surface where you need traction and a stable wearing course. Combining geotextile fabric, larger drainage rock, and a compacted crushed stone layer gives the best long-term performance on Blackhawk slopes.

Hello Gravel connects Blackhawk homeowners with local suppliers and contracted haulers who deliver bulk gravel by dump truck; availability depends on your zip code. Most local suppliers will deliver a minimum order (we list 3 tons) and some drivers may offer tailgate spreading at their discretion—request it in your order notes but know it is not guaranteed. Use our site to shop materials, check availability, and add spreading requests or call our team for help.

Measure the area (length x width) to get square footage, decide on the depth in inches, then multiply square feet by depth (in inches) and divide by 324 to get cubic yards (for example, 400 sq ft at 3u0022 depth = 400*3/324 = 3.7 cubic yards). Convert cubic yards to tons using local density (about 1.3 to 1.5 tons per cubic yard depending on material) or use Hello Gravel's online calculator for an instant estimate. When in doubt, order a bit extra (5-10%) to allow for compaction and grading.
