The Soiland Family and Stony Point Rock Quarry have a long-term vision: To remain good stewards of our resources and talents so that we can continue to support and improve our community into the future.  
Stony Point Rock Quarry, Inc. has provided rock and soil products to consumers and contractors in Sonoma County for over 100 years. A variety of construction-grade aggregate products and various top soil mixes are available from Stony Point’s Cotati and Sonoma locations.

Homeowners can purchase a variety of aggregate products, soil mixtures, and soil amendments at wholesale prices. Pick up is easy when we load your pickup or haul trailer with the quantity you wish to purchase. Our Cotati yard is close to the Sonoma County Mecham Road Central Landfill and our Sonoma yard is adjacent to the Sonoma Transfer Station. This makes it convenient for consumers to haul garbage to the dump and return with products for their home improvement projects. Delivery of larger quantities is also available.
