Material Selection by Project Type

• Driveways: Use 3/4 inch crushed stone or Stone Screenings as a base layer. A compacted base prevents rutting and provides a stable surface for parking and turning.
• Drainage: Crushed Stone or river rock works best around foundations and in French drains. Material without fines allows water to flow through freely without clogging.
• Patios and walkways: Start with a compacted crushed stone base, then top with Natural Pea Gravel or Stone Screenings for a finished surface. The base keeps pavers and stepping stones level.
• Landscape beds and soil work: Screened topsoil or garden soil enriches planting beds, while river rock or decorative gravel provides weed suppression and visual contrast.

Local Conditions That Affect Material Choice

ZIP 94979 in San Anselmo includes a mix of older built-up neighborhoods and larger hillside lots with mature trees. Soil in the area can range from well-draining loam to tighter clay pockets, especially on steeper slopes.

Winter rains are common, so drainage and erosion control are important. On sloped properties, angular crushed stone locks into place better than round rock, reducing downhill shifting. In flat areas, Stone Screenings or sand works well for patios and pathways.

Freeze-thaw cycles are mild but occasional. Base materials that drain well help prevent frost heave in driveways and walkways. The varied topography means material selection often depends on whether the site is level, sloped, or tucked between existing structures.

Delivery and Access in ZIP 94979 of San Anselmo

American Rock Supply delivers to much of ZIP 94979. Trucks can access most driveways and streets in the area, but long rural driveways or narrow lanes may require advance planning.

Tight suburban lots with limited turnaround space work best when the drop location is clearly marked. Soft ground after heavy rain can cause ruts, so consider where the truck will unload.

Overhead branches and wires are common in established neighborhoods. Let the driver know about any clearance issues. Contractor jobs with larger quantities often allow more flexible drop locations than single-load homeowner orders.
