Material Selection by Project Type

• Driveways: Use 3/4 inch crushed stone as a base layer. It compacts tightly and resists rutting under vehicle weight. A top layer of Natural Pea Gravel or asphalt millings can add a finished surface.
• Drainage: Crushed Stone without fines allows water to flow freely. Avoid crusher run or stone dust near foundations because fines can clog drains.
• Patios and walkways: A 4-inch compacted crushed stone base with a 1-inch layer of concrete sand on top provides a stable, level bed for paving stones.
• Landscape beds and soil work: Topsoil enriches planting areas, while hardwood mulch suppresses weeds and holds moisture. Decorative stone like Natural Pea Gravel works well for dry stream beds or borders.

Local Conditions That Affect Material Choice

ZIP 94131 in San Francisco sits on steep hills and older residential blocks. Many lots have narrow driveways and limited level space. Soils here often contain clay or fill, which drains slowly after rain.

Homes on slopes need angular crushed stone for driveways to prevent washout. Flat areas with heavy clay benefit from a thick gravel base to improve drainage and reduce settling.

The mild coastal climate means freeze-thaw is rare, so base materials do not need extra frost protection. But heavy fog and winter rain can soften ground, making a solid compacted base essential.
