Stone in Phoenix, AZ

In Phoenix, "stone" usually refers to crushed natural rock used as an aggregate (not sand or decomposed granite). Common sizes are 3/8", 3/4", 1" and 1-1/2"; smaller sizes (3/8"-3/4") are used for walkways and compacted surfaces, while 3/4"-1" and larger are common for driveways, drainage, and xeriscape accents.

Typical delivered prices for common crushed stone in Phoenix range roughly $35 to $55 per ton, which is about $45 to $72 per cubic yard (using ~1.3 tons per cubic yard). Final price depends on size, color, supplier, and delivery distance; check your zip code on Hello Gravel for exact quotes and any available promotions.

For driveways in Phoenix, a 3/4" crushed stone surface over a compacted gravel base (4"-6") is a common, durable choice. Walkways and patios do well with 3/8" to 3/4" for a smoother finish, while xeriscape gardens and decorative areas often use 3/4" to 1-1/2" for visual texture and better drainage. Lighter color stone helps reduce surface heat in sunny locations.

Monsoon rains can cause localized washout and migration of loose stone, so proper compaction, geotextile fabric, and edge restraints are important. High summer heat can fade color and make surfaces hot to the touch; choosing lighter-colored stone and using an adequate depth helps reduce heat transfer and movement. Inspect low spots after heavy storms and replenish where needed.

Use a 4"-6" compacted crushed-rock base for driveways with a geotextile fabric beneath and an edge restraint to prevent migration, then top with 1"-3" of surface stone depending on traffic. For pedestrian paths and patios, 2"-3" of surface stone over 3"-4" compacted base is typical. Always overlap fabric, compact in lifts, and slope the surface for drainage away from structures.

As a rule of thumb, 1 cubic yard ≈ 1.3 tons. A typical 2-car driveway (20'x20') at a 3" finish requires about 3.7 cubic yards (≈ 4.8 tons); if you need a full 6" structural depth expect about 7.4 cubic yards (≈ 9.6 tons). A 12'x12' patio at 2" needs about 0.9 cubic yards (≈ 1.2 tons); a 3-foot-wide 50-foot pathway at 2" needs about 0.9 cubic yards (≈ 1.2 tons) as well. Always order 5%-10% extra for compaction, leveling, and spillage.

Material-only delivered costs for a basic crushed stone driveway in Phoenix typically run from several hundred to a few thousand dollars depending on size (using the per-ton ranges above). Professional installation (base prep, compaction, edging, labor) commonly adds $5 to $10 per square foot, so a 20'x20' driveway could cost roughly $2,000 to $4,000 installed. Prices vary by site conditions, accessibility, and contractor rates; get multiple local quotes and check Hello Gravel for material pricing to compare.

Many Phoenix-area HOAs and some city neighborhoods have design rules that cover front-yard materials, permeable surface limits, and allowed colors; requirements vary widely by HOA and municipality. Before changing front-yard landscaping or replacing a driveway, review your HOA covenants and contact the City of Phoenix planning or code office if you have questions about permits or impermeable surface standards. When in doubt, get written approval from your HOA or a permit determination from the city.

Crushed stone is durable, drains well, and resists displacement when properly installed, but loose stone can migrate and gets hot in direct sun; lighter colors reduce heat absorption. Decomposed granite packs firmer and can be stabilized, offering a smoother walking surface but it can produce dust and rut under heavy traffic. Basalt is dense and dark (gets hotter), while pavers are the most permanent and level solution but are costlier and can trap heat; choose based on budget, desired look, and how you use the space.

Expect to do light maintenance: seasonal raking to redistribute stone, remove debris after storms, spot replenish low or washed-out areas, and apply pre-emergent weed control once or twice a year. In Phoenix you may need to replenish stone every 1-3 years depending on foot/vehicle traffic and monsoon washout. Install good edging and fabric to reduce migration and cut maintenance needs.
