Gravel in Kenmore, WA

Prices vary by type and quantity, but expect roughly $40 to $80 per ton delivered for common gravels in the Kenmore area. Hello Gravel has a 3-ton minimum order; many listings include delivery in the price, but fees can appear for small orders, long hauls, or expedited service. Check your zip code at checkout for an exact delivered price and available delivery windows.

Common local options include 3/4u0022 crushed rock (good base material for driveways), 3/4u0022 clean or washed rock (excellent for drainage), pea gravel and river rock (decorative pathways and beds), and crusher-run or 3/4u0022 minus (compacted base). Suppliers in West Washington source materials locally, so appearance and color can vary but the typical uses remain the same: base, finish, drainage, and landscaping accents.

Use this rule: cubic yards = (area in sq ft * depth in inches) / 324, then multiply cubic yards by about 1.4 to get tons. For example, a 1-car driveway of 240 sq ft with a 6u0022 base plus 2u0022 topcoat needs roughly 8 to 10 tons total. Walkways at 2-3u0022 depth typically require about 1.2 to 1.5 tons per 100 sq ft.

Kenmore's frequent rain increases the chance of washout and rutting if surfaces lack proper slope and drainage. Use angular, compactable base stone for stability and washed drainage rock where water must move, and install a slight crown or slope to shed water. Geotextile fabric and edge restraint help prevent migration when soils are saturated.

A layered approach works best: 4 to 6 inches of crushed rock or crusher-run (3/4u0022 minus) compacted as the base, topped with 1.5 to 2 inches of 3/4u0022 crushed or 3/8u0022 crushed rock as a driving surface. Avoid smooth river rock for the main driving surface because it shifts and compacts poorly in wet conditions. Finish choices depend on look and budget, but angular crushed stone gives the most stable result in West Washington.

Rules vary by project and neighborhood; some Kenmore properties and HOAs have restrictions on front yard surfacing, impervious surface limits, or stormwater requirements. Check the City of Kenmore planning department and any HOA covenants before starting work, and get written approval if your neighborhood requires it. If in doubt, contact our team and we can point you toward local resources.

Expect routine maintenance such as occasional raking to redistribute stone, adding fresh gravel to low spots, and spot-compacting after heavy rains. In Kenmore's climate, light-use gravel surfaces typically need replenishment every 2 to 5 years, while high-traffic driveways may need topping every 1 to 3 years. Weed control and edge maintenance will extend lifespan and reduce migration.

Gravel has the lowest upfront material and installation cost and provides excellent drainage, but it requires more frequent maintenance and replenishment. Asphalt offers a smoother, longer-lasting surface (often 15 to 25 years) but is more expensive, less permeable, and may require permits or stormwater controls. Pavers are the most expensive up front but are durable and attractive; choose based on budget, drainage priorities, and local restrictions.

Hello Gravel requires a 3-ton minimum order and typically delivers via tri-axle dump trucks. Standard delivery lead time is 2+ business days, with next-day delivery sometimes available for orders placed early (additional fee may apply). Suppliers generally deliver within a regional radius—often 10 to 50 miles—so delivery fees and availability depend on your zip code.

Many homeowners can DIY small projects like pathways or small pads, but larger driveways or projects on slopes benefit from a contractor to prepare base, grade, and compact properly. Installation costs vary widely by scope, but expect labor and base work to add roughly $10 to $30 per ton or $1 to $4 per sq ft depending on prep needs and site conditions. Get multiple local quotes for installation to compare with a DIY approach.

First use the standard volume formula (area * depth / 324) to get cubic yards, then add an allowance for slope: add 10% for mild slopes, 15% to 25% for moderate to steep slopes to account for extra volume and settling. Mark and measure the high and low points and consider terracing or edging to limit migration on steep sites. If unsure, request a site visit or use Hello Gravel's calculator and add a contingency percentage.

Prepare a compacted base with angular crusher-run stone, install a geotextile fabric to separate soil and stone, and slope the surface to shed water away from structures. Use solid edging (timber, metal, concrete, or pavers) to hold material in place, and install perimeter drainage or swales where runoff concentrates. These steps reduce washout and make the surface easier to maintain in a wet climate.
