If you just closed on a new build in Gilbert, there is a good chance your back yard is a rectangle of bare dirt and your driveway is about to have a rock pile on it. Gilbert has around 260 new-home communities right now, and phases are still delivering in Cooley Station, Morrison Ranch, Waterston North, and Spectrum at Val Vista. Builders hand you the house. The yard is on you.
I get the same call every week: “How much rock do I actually need, and what do I do with it once it is sitting in my driveway?” Here is the honest answer, math included.
First, the one thing to know: we can handle the whole thing
We can deliver the rock for you, or you can have a yard drop it in your driveway — either works. What matters is the part almost nobody wants to think about until it is sitting there: moving fourteen tons from the driveway to the back yard through a three-foot side gate. That is what we do. We move it, spread it to an even 2-inch depth, hand-rake around trees, AC units, and pavers, and blow the driveway clean. Delivered and spread, or just spread. Your call.
How much landscape rock do I need? The actual math
Rock is sold by the ton in Arizona, but coverage is a volume problem. The formula:
square feet × depth in inches ÷ 12 = cubic feet
cubic feet ÷ 27 = cubic yards
cubic yards × 1.4 = tons
That 1.4 is the rough weight of a cubic yard of 1/2-inch to 3/4-inch screened granite. Worked example, a 1,500 sq ft front yard at 2 inches:
1,500 × 2 ÷ 12 = 250 cubic feet. 250 ÷ 27 = 9.3 cubic yards. 9.3 × 1.4 = about 13 tons.
Two inches is the number to design around. Thinner and the dirt grins through and weeds find daylight; thicker and you are paying for rock nobody sees.
Ballpark by yard size (2-inch depth)
| Area | Cubic yards | Tons | Typical RockSpread job |
|---|---|---|---|
| 500 sq ft | 3.1 | ~4–5 | $475 |
| 800 sq ft | 4.9 | ~7 | ~$700 |
| 1,200 sq ft | 7.4 | ~10–11 | ~$700–950 |
| 1,500 sq ft | 9.3 | ~13 | ~$950 |
| 2,000 sq ft | 12.3 | ~17 | Quoted |
| 2,500 sq ft | 15.4 | ~22 | Quoted |
Round up, never down. Coming up a ton short means a second delivery fee for a pile you could have covered the first time.

Rock size and color, the Gilbert version
Three-quarter-inch screened is the workhorse: it locks together, stays put, and does not roll into the street. Half-inch reads finer and is easier on bare feet, but it migrates and it tracks into the house. Anything over an inch looks great in photos and is miserable to rake around. Skip pea gravel in a dog yard unless you enjoy finding it indoors.
On color, remember the sun here is not subtle. A rock that looks warm brown in the yard sample bin turns bright orange under a Gilbert July at 2 p.m. Take the sample home and look at it at noon, in your yard, not under the fluorescents at the supplier.
Check your HOA before the truck comes, not after
Gilbert is HOA country, and the design guidelines are real. Communities like Power Ranch and The Islands publish architectural guidelines that govern front-yard landscaping, and the pattern across most Gilbert associations is consistent: no bare dirt, a limit on how many rock colors you can use in the front yard (often two), weed barrier under the granite, and an approved plant list. Most architectural review committees want a plan submitted before installation and take a couple of weeks to respond.
Pull your community's guidelines and submit early. Rock is cheap to plan and expensive to redo.
The part nobody budgets for: moving it
Thirteen tons is roughly 130 wheelbarrow loads. In a Gilbert July, at 110 degrees, through a side gate, that is not a Saturday project, it is a hospital visit. Our compact skid steer fits a standard 3 to 4 foot side gate, so the material goes where it is going in one day instead of over three weekends.
What about the old rock?
Worth knowing before you start a re-rock: Gilbert's bulk trash program will not take it. The town explicitly excludes demolition debris including rock, dirt, sod, and concrete, and bulk pickup only comes around every five weeks anyway. Old rock is not going to the curb. We haul it off in a 14,000-lb dump trailer, one trip, gone.
Getting a number
Text three photos to (602) 918-5369: the pile, your gate, and the yard. That is genuinely all we need, no site visit. You get one flat number back, usually within the hour. Jobs start at $475 and the price is the price. More detail on how we work and what we charge is on our home page.
FAQ
How much rock do I need for a 1,500 sq ft yard in Gilbert?
About 13 tons at a standard 2-inch depth, which works out to roughly 9.3 cubic yards. Round up when you order, since a short load means paying a second delivery fee.
Does RockSpread deliver the landscape rock too?
Yes, we can deliver the material as well as spread it. Plenty of customers also have their own rock yard drop the pile in the driveway and just bring us in for the spreading. Either way works. Tell us which you would like when you text photos for a quote.
Can I put my old landscape rock out for Gilbert bulk trash?
No. Gilbert's bulk trash program excludes demolition debris such as rock, dirt, sod, and concrete. Old rock has to be hauled to a transfer station or removed by a hauler. We handle haul-off in our dump trailer.
