Material Selection by Project Type

• Driveways: For residential driveways in Bolinas, compactable materials like crushed stone (3/4" minus) or Stone Screenings provide a stable, long-lasting surface. A base layer of larger stone may be needed on soft or sloped sites.
• Drainage: Crushed Stone or drain rock works best where water movement is critical. Materials with fines (like crusher run) can clog drainage systems, so use washed stone around foundations and French drains.
• Patios and walkways: Use a compacted base of crushed stone (3/4" minus) or Stone Screenings, then top with a setting bed of clean sand or fine gravel. This prevents shifting and frost heave in coastal conditions.
• Landscape beds and soil work: Decorative stone, mulch, or topsoil improve planting beds. For native soil in Bolinas, amending with topsoil or garden soil helps retain moisture in sandy areas and improve drainage in clay pockets.

Local Conditions That Affect Material Choice

Bolinas sits along the Marin County coast with a mix of older built-up lots near the water and larger acreage properties in the hills. Soils vary from well-draining sand near the beach to heavier clay in upland areas.

The mild coastal climate means freeze-thaw cycles are rare, so base materials do not need heavy frost protection. However, winter rains can saturate the ground, making drainage a priority for driveways and patios.

Steep slopes and narrow, winding roads are common. Material selection often shifts between compactable base for stable driveways and clean stone for managing runoff on sloped properties.
