Gravel in Kenwood, CA

Costs vary with gravel type, quantity, and distance from supplier, but many homeowners in small Sonoma County towns see material prices plus delivery fees. Hello Gravel has a 3-ton minimum and offers free delivery in many areas, while other locations may add a delivery charge or per-ton fee; bulk orders usually reduce the per-ton price. The fastest way to get a firm cost is to enter your zip code on our site or request a local quote so we can show material and delivery estimates for Kenwood.

For Kenwood's hilly terrain and Mediterranean climate, angular crushed stone (commonly 3/4u0022 to 1u0022) with some fines for binding is a good choice because it locks together and resists washout. Decomposed granite (DG) with stabilizer works well for lower-traffic driveways and blends with the landscape, while pea gravel is less ideal on slopes because it moves more easily. Use a compacted base and edging to prevent migration on steeper driveways.

A common 2-car driveway is about 20 ft by 40 ft (800 sq ft). At 3u0022 depth you'll need roughly 7.4 cubic yards or about 10 to 11 tons; at a 6u0022 compacted base plus 2u0022 surface you could need 18 to 22 tons. Always add 10% to 15% for compaction, slope, and waste, and factor in extra material if you are building a deeper base for steep sections.

Yes, many local suppliers and haulers in Sonoma County offer lower per-ton pricing on larger orders and occasional delivery discounts, especially for on-site contractors. Hello Gravel negotiates local rates and can often show bulk pricing and delivery options when you request a quote; however, discounts and free delivery aren’t guaranteed and depend on your zip code and job size.

Kenwood’s wet winters and dry summers mean you need materials that handle both runoff and summer dust. Choose angular gravel or mixes with some fines to stay stable through winter rains, add proper drainage and edging, and expect to rake and touch up high-traffic areas after the wet season. In dry months, occasional watering or a stabilizer can reduce dust and movement on pathways and driveways.

For walkways, 3/8u0022 crushed gravel or decomposed granite placed over a compacted 3/4u0022 crushed stone base (2 to 4u0022 compacted) provides a firm, low-maintenance surface. Use edging to keep material contained and consider a permeable weed barrier to reduce weed growth while allowing water to drain. For steeper areas, increase base depth and add small crib walls or edging to prevent slumping.

Gravel driveways typically cost significantly less up front than concrete or pavers because materials and installation are simpler, and delivery is often the main expense. However, gravel requires periodic maintenance and top-ups, so long-term costs depend on traffic, drainage, and how well the base was built. Ask Hello Gravel for local material and delivery quotes so you can compare initial install costs for your Kenwood property.

With proper base preparation and drainage, many gravel driveways in Sonoma County need only minor top-ups every 1 to 3 years, while major replenishment or full resurfacing is often required every 5 to 10 years depending on traffic and erosion. Heavier traffic, poor drainage, or steep slopes shorten that timeline and may require earlier attention. Regular maintenance—raking, re-grading ruts, and fixing drainage—extends the life of the surface.

Permeable gravel systems can be a good fit in Kenwood because they promote infiltration and reduce runoff during winter rains, which is helpful for steep lots and some septic drain-field situations. Before installing permeable surfaces, check Sonoma County permitting and septic regulations since specific setbacks and materials may be required. A common permeable approach uses larger, angular stone with an open-graded base and geotextile to maintain infiltration while preventing subgrade contamination.

For erosion control on slopes, use larger angular stone (1u0022 to 3u0022 crushed rock or small riprap) and combine it with geotextile fabric and properly sized swales or drains to slow runoff. Depths often range from 3u0022 for surface protection to 6u0022 or more in high-flow channels; for example, 100 sq ft at 3u0022 depth is about 0.93 cubic yards or roughly 1.3 tons. Because slope angle and soil conditions matter, consider a site-specific assessment for steeper or high-erosion areas.
