Gravel & Rock ordered online by the ton. A dump truck delivers to your Gpo address and unloads right where you point.







The size of gravel or rock you choose changes how it drains, how it compacts, and how it stays in place. Gpo gets about 73 inches of precipitation a year, so drainage and washout planning matter for any project. Larger rock handles runoff better, while finer material compacts into a firm surface.
Gravel Monkey stocks a variety of sizes, from fine decomposed granite to large river rock. Each product has a specific job, and choosing the right one saves work later. The delivered price is shown at checkout before you commit.
The most commonly ordered product in Gpo is 3/8" Natural Pea Gravel, used for play areas and patios where a rounded, smooth surface is needed. The other sizes serve different purposes, from compactable base to erosion control. Compare them in the table below.
| Product | Use | Note |
|---|---|---|
| 3/8" Natural Pea Gravel | Play areas, patios | Rounded and smooth, compacts well under foot |
| River Rock | Beds, borders, dry creek beds | Varied sizes give a natural look |
| 2-4" River Rock | Larger decorative cover and erosion control | Handles heavy runoff |
| Drain Rock | French drains and dry wells | Clean, angular stone moves water fast |
| Decomposed Granite | Paths and patios that compact firm | Compacts to a hard, stable surface |
| Crusher Run | Compacting base under everything | Contains fines that lock together |
| Road Base | Lanes and pads that carry trucks | Heavy-duty load support |
Use this table to match your project to the right product and recommended depth. Each depth assumes a stable subgrade and, where needed, landscape fabric underneath.
| Project | What to order | Depth or note |
|---|---|---|
| Landscape beds | River Rock | 2 to 3 inches deep for weed suppression and moisture retention |
| Dry creek bed | 2-4" River Rock | 3 to 4 inches deep with fabric underneath |
| Path that stays firm | Decomposed Granite | 2 to 3 inches compacted over a crushed stone base |
| French drain | Drain Rock | Placed in a trench wrapped in landscape fabric |
| Erosion control on a slope | 2-4" River Rock | 4 to 6 inches deep, keyed into slope |
Gpo gets about 73 inches of precipitation a year, so drainage and washout planning are important for any gravel or rock installation. Base materials like crusher run need a well-draining subgrade.
With about 0 days a year dropping below 32F, the ground does not freeze and shift. That means you can compact and place material any time without frost heave. Order once the site is ready, because material sitting in the wrong spot gets moved twice.
To estimate how many tons of gravel or rock you need, measure the length and width of the area and decide the depth. A cubic yard covers about 100 square feet at 3 inches deep, and each product has its own weight per yard. Use the material calculators on our site to get a tonnage estimate for your dimensions.

To estimate tonnage, measure the area and depth. Gpo has about 118 days a year with at least a tenth of an inch of rain, so consider drainage when choosing depth for walkways and patios. Use our material calculators for an accurate tonnage.

Smaller sizes like pea gravel and decomposed granite work for paths and patios where a firm, compacted surface is needed. Larger rock like 2-4" river rock handles erosion and heavy drainage. Each product has a specific use listed in the product table above.
