Gravel in San Simeon, CA

Hello Gravel requires a 3-ton minimum order.

For San Simeon, angular crushed rock (e.g., 3/4u0022 crushed) and hard igneous stones like basalt or granite perform well because they resist salt damage and compact for stability. River rock and pea gravel resist salt spray too but are rounded and can shift more, so they are better for decorative areas or pathways rather than driveways. Decomposed granite can work for paths and low-traffic xeriscapes but may need stabilizer and more maintenance near salty, wet air.

A 12 x 30 ft driveway at 4 inches deep equals about 120 cubic feet, or roughly 4.44 cubic yards. Crushed gravel typically weighs about 1.5 tons per cubic yard, so you would need about 6.7 tons. Order at least 10% extra for compaction and waste, so plan on ordering about 7.5 to 8 tons; Hello Gravel's 3-ton minimum will cover small jobs.

Installation pricing varies by scope, access, and grading needs. For San Luis Obispo County area, expect rough ranges of $1.50 to $5.00 per square foot for a basic gravel driveway that includes grading and material, or approximately $40 to $100 per ton installed for projects requiring base work and compaction. Always get at least two local quotes and ask contractors to itemize base prep, drainage, and hauling.

Yes. San Simeon properties fall under San Luis Obispo County planning rules and possibly the California Coastal Commission if you are in the coastal zone, so check with the San Luis Obispo County Planning Department before major grading or changes to driveway footprint. Also check any HOA or community covenants for surface and aesthetic rules. Smaller surface changes or top dressing may not require permits, but anything involving grading, retaining walls, or runoff control often does.

Salt spray accelerates surface weathering on softer rocks like some limestones or sandstones, so choose harder materials such as granite, basalt, quartzite, or well-graded crushed rock for driveway use. Proper drainage, edge restraint, and vegetation are critical to limit erosion near cliffs and bluffs; gravel alone will not prevent undercutting or major washouts. For bluff-top or cliff-adjacent sites, consult a local engineer or the county for erosion-control guidance before placing material.

Contractors commonly install a structural base of 6 to 8 inches of larger crushed rock (3/4u0022 to 2u0022 minus) compacted in 2 to 3-inch lifts, followed by a 2 to 3-inch wearing layer of 3/4u0022 crushed stone. They typically place geotextile fabric under the base in poor soils, build a slight crown (about 1/4u0022 per foot) for drainage, and add turnouts or check-steps and water bars on steep runs. Proper compaction (contractor target often 90%+ relative compaction) and good drainage are the most important defenses against ruts and washouts.
