Material Selection by Project Type

• Driveways: Use a compactable crushed gravel with fines (3/4" minus). It locks together under compaction and provides a stable surface for vehicles. A 4-inch base is common for residential drives.
• Drainage: Choose Crushed Stone (no fines) around foundations, in French drains, or behind retaining walls. Water passes through without clogging. Natural Pea Gravel works for smaller trench drains.
• Patios and walkways: Lay a crushed gravel base (compacted) and top with a 1-inch setting bed of Stone Screenings or sand. Then place pavers or flagstone. Stone Screenings alone can act as a finished path.
• Landscape beds and soil work: For planting beds use screened topsoil or garden soil. Decorative gravel like Natural Pea Gravel or river rock provides a clean, low-maintenance surface around plants.

Local Conditions That Affect Material Choice

ZIP 92139 in San Diego covers mostly suburban and residential areas with a mix of older built-up lots and newer subdivisions. Many properties sit on gentle to moderate slopes.

Soil in this part of San Diego tends to be clay-rich in some spots and sandy in others. Clay holds water longer, so driveways and patios benefit from a thick, compacted base of crushed gravel to prevent settling.

Sloped sites require crushed stone for drainage to redirect runoff away from structures. The mild San Diego climate eliminates freeze-thaw concerns, so material selection focuses on drainage and compaction rather than frost resistance.
