Figuring out how much is a cubic yard of river rock is a common starting point for anyone looking to enhance their waterside property, whether it’s for a new dock pathway or to neaten up a marina’s common area. The answer isn’t a simple number, as the price is influenced by a variety of factors, from the type of stone you choose to your location. This guide will break down everything you need to know, ensuring your project is both beautiful and budget-friendly. Understanding this popular landscaping material is key to effective erosion control and creating practical drainage solutions, all of which contribute to your final project cost.
Understanding the Basics: What Exactly is a Cubic Yard?
Before we dive into pricing, let’s get a handle on the measurement itself. A cubic yard can be a tricky thing to visualize if you’re not used to it. Imagine a cube that is 3 feet long, 3 feet wide, and 3 feet high. That volume is one cubic yard. It’s roughly the size of a standard home washing machine or a large armchair.
This measurement is crucial because it determines how much area you can cover. A single cubic yard of river rock, spread at a recommended depth of about two inches, will typically cover an area of around 160 square feet. This is a vital number to keep in mind when you start planning the scale of your project, be it a small decorative patch or a long, winding path down to your boat slip.
The Core Question: How Much Is a Cubic Yard of River Rock?
So, let’s get to the heart of the matter. On average, you can expect to pay anywhere from $100 to over $300 for a cubic yard of river rock. That’s a pretty wide range, and it’s because several key variables come into play. Understanding these factors will help you narrow down your expected cost and find the best value for your specific needs.
The Type and Size of the Rock
Not all river rocks are created equal. The most significant factor impacting the price is the type of stone itself. Standard, locally sourced river rocks in common earth tones will be on the lower end of the price spectrum. These are perfect for functional applications like drainage beds or filling in large areas.
However, if you’re looking for something more decorative, such as highly polished, uniformly sized, or uniquely colored stones (like deep blacks or vibrant reds), the price will climb. These premium rocks are often sourced from specific regions and undergo more processing, which adds to the cost. The size also matters; smaller, more uniform pebbles often cost more than larger, more irregular cobbles because they require more sorting.
Your Supplier and Location
Where you buy your river rock makes a huge difference. Sourcing directly from a local quarry or a dedicated landscape supply company is often the most cost-effective route. They deal in bulk and have lower overheads compared to big-box home improvement stores.
Your geographical location also plays a massive role. If you live in a region where river rock is abundant, transportation costs are lower, and so is the price. Conversely, if the rock has to be trucked in from hundreds of miles away, you can expect that shipping cost to be reflected in the final price per yard. It always pays to shop around and compare prices from at least two or three local suppliers.
Delivery and Installation Costs
The price tag on the rock itself is just one part of the equation. You also need to consider how you’ll get it to your property. Most suppliers offer delivery for an additional fee, which can be a flat rate or a per-mile charge. For large projects, this is almost always a necessity, as a cubic yard of rock is incredibly heavy.
Then there’s the installation. Are you planning a DIY project? If so, your cost is your time and effort. If you’re hiring a professional landscaping crew to spread the rock, lay down fabric, and create clean edges, you’ll need to budget for their labor, which can sometimes equal or exceed the cost of the materials themselves.
As Marina Landscape Architect, David Chen, often advises, “Clients are sometimes surprised that delivery and labor can make up 50% of the total budget for a rock installation. It’s not just the material; it’s the logistics of moving tons of stone and the expertise to lay it properly for longevity and proper drainage.”
Beyond the Price Tag: Calculating Your Total Project Cost
Knowing the per-yard price is one thing, but understanding your total project outlay is what truly matters. This requires a bit of simple math and planning for all the necessary components, not just the stones.
How Much River Rock Do You Actually Need?
To avoid over or under-ordering, you need to calculate the volume of your project area. The formula is straightforward: multiply the Length (in feet) by the Width (in feet) by the Depth (in feet), and then divide that total by 27 to convert it into cubic yards.
For example, let’s say you’re creating a pathway to your dock that is 40 feet long, 4 feet wide, and you want the rocks to be 2 inches deep (which is 0.167 feet).
- 40 ft (L) x 4 ft (W) x 0.167 ft (D) = 26.72 cubic feet
- 26.72 / 27 = 0.99 cubic yards
So, for that project, you’d need to order one full cubic yard. Always round up to the nearest half or full yard to ensure you have enough.
Factoring in Additional Materials
A successful river rock installation requires more than just the rock. To prevent weeds from poking through and to keep the stones from sinking into the soil, you’ll need a high-quality landscape fabric underneath. You’ll also likely need some form of edging—whether it’s metal, plastic, or stone pavers—to contain the rocks and create a clean, finished look. Don’t forget to budget for these essential extras, as they are crucial for the long-term success of your project.
Why River Rock is a Smart Choice for Waterside Properties
For boat owners and marina managers, river rock offers a unique set of benefits that make it an ideal choice for landscaping near the water. Its primary advantage is excellent erosion control. Placed along shorelines or on gentle slopes, it helps to dissipate wave energy and prevent soil from washing away. This is particularly important in areas where water levels can fluctuate. For those interested in local water conditions, understanding data related to the wolf river water levels new london can provide context for how crucial such preventative measures are.
Furthermore, its permeability makes it a fantastic material for drainage solutions. It allows rainwater to seep through into the ground, preventing puddles from forming on pathways or around dock foundations. This is a much better alternative to non-porous surfaces like concrete, especially in areas prone to heavy rain. Monitoring water tables, similar to checking the greenbrier river water level alderson today, can help in designing effective drainage systems for your property. The effectiveness of rock-based landscaping is also influenced by the movement of water, making insights into the rogue river flow at grants pass a valuable parallel for understanding how natural forces interact with man-made structures.
What Factors Influence the Weight of River Rock?
A common follow-up question is about the weight of the material. The weight of river rock is influenced by its density, type, and moisture content. Generally, a cubic yard of dry river rock can weigh between 2,400 and 2,800 pounds (well over a ton). This is why delivery is so important! To understand this better, it’s helpful to consider the specifics of how much does one cubic yard of river rock weigh.
The composition of the stone is the main factor. Dense rocks like granite will weigh more than porous ones like sandstone. If the rock is wet, it will have absorbed water, increasing its weight significantly. This concept is closely related to the general weight of river rock per yard, which is a critical piece of information for anyone planning the logistics of their project.
David Chen adds, “We always calculate based on the higher end of the weight estimate. It ensures the delivery truck is properly equipped and that we don’t underestimate the structural needs for features like retaining walls. The last thing you want is a logistical failure on installation day.”
Are There Alternatives to River Rock for Dock and Marina Landscaping?
While river rock is an excellent choice, it’s worth considering other options to ensure you’re making the best decision for your property and budget. Each material has its own pros and cons, especially in a waterside environment.
| Material | Pros | Cons | Best For |
|---|---|---|---|
| River Rock | Excellent drainage, durable, low maintenance, great for erosion control. | High initial cost, heavy to install, can be difficult to walk on. | Shorelines, drainage beds, decorative pathways. |
| Pea Gravel | Cheaper than river rock, smaller and easier to walk on, good drainage. | Can get displaced easily, gets hot in the sun, not ideal for slopes. | Walkways, patios, play areas. |
| Wood Mulch | Inexpensive, improves soil health, natural look. | Needs replacing every 1-2 years, can wash away in heavy rain or floods. | Garden beds away from the immediate shoreline. |
| Paving Stones | Very durable, stable walking surface, variety of styles. | Most expensive option, requires extensive ground prep, can be slippery when wet. | High-traffic patios, main walkways, dock aprons. |
Ultimately, the best choice depends on your specific application, aesthetic preference, and long-term maintenance goals.
In summary, the answer to how much is a cubic yard of river rock is a range, typically between $100 and $300, but the total cost of your project will depend heavily on the type of rock, your supplier, delivery fees, and whether you tackle the installation yourself. By carefully calculating your needs, budgeting for additional materials, and choosing the right stone for your waterside property, you can create a beautiful, functional, and long-lasting landscape that enhances your enjoyment of the water.

As a DIYer, the calculation formula was exactly what I was looking for. I was about to guess and would have been way off. Ordered one cubic yard for a French drain project next to our boat house and it was the perfect amount. Thanks!

Good information, but I wish it mentioned the difference between smooth river rock and crushed angular rock a bit more. We ended up using the angular type for our driveway because it locks together better and doesn’t shift as much. River rock is definitely prettier for walking paths though.

Solid advice. We used river rock to create a dry creek bed for runoff at our marina, and it’s worked wonders. It looks natural and handles a huge amount of water during storms. The point about it being a great drainage solution is 100% true.
