Boulders, Berms, and Swales in Marana, Oro Valley, and Tucson

At The Garden Gate, we install boulders, berms and swales at residential properties in Tucson, Marana, and Oro Valley. On a new home construction project, the landscape plan will identify the location of all boulders, berms, and swales. For existing homes, we can provide a plan or we can walk the property and identify the areas where they should be placed.

Often used to improve the natural appearance of your landscape, boulders, berms, and swales are also used to mitigate erosion and control water flow (rainfall).  We design and build landscapes that look natural and perform well in the desert.

Precision Plans and Renderings

AutoCADdrawings and 3D renderings that ensure accuracy, clarity, and confidence.

Form, Function, and Placement

While the addition of boulders can improve the way your yard looks by anchoring spaces and creating planting opportunities, they can also be a key focal-points when placed properly.

Focal Points

Boulders clustered together in various sizes mimic the desert geology by creating rock outcroppings, where you want them. Boulders are typically installed 1/3 below the surface for stability and a realistic look.

Boulder Walls

Large boulders are often used to build natural looking retaining walls in lieu of masonry retaining walls, usually at a lower cost.    

Colors

Boulders come in many colors, shapes, and sizes. In new construction projects boulders are often salvaged from the site including "Surface Select" boulders. These boulders are found on the surface and have a darker patina. The boulders buried underground that are salvaged during the excavating / grading work are called "Catalina boulders" and are a lighter color with no patina.  

Berms and Swales

Berms can include boulders and plants, adding interest and elevation changes (instead of flat yards) and swales help guide water away from the house.

Erosion and Drainage

Heavy rain can cause erosion damage near homes and along driveways. Swales, often lined with rock are designed to direct water flow toward desert washes and other approved  areas.

Integrated With Your Outdoor Living Plan

Boulders, berms and swales can be incorporated in the landscape design for new construction projects as part of our turnkey service, or installed at existing homes.

Our Installation Process

The Project Coordinator orders the boulders (and fill soil if needed) and sets the installation schedule with you. The crew leader installs the boulders, berms and swales according to the landscape design, or the placement you approved. With support from the Project Supervisor, final placement and contouring is completed.  

Cost Ranges

Costs are determined by boulder size, type and whether they are salvaged from the site or purchased from a supplier. Most boulders salvaged or excavated from residential properties range in size from 1’ x 2’ to 3' x 4’ and can be larger. Smaller boulders can be placed by hand and larger boulders are placed with a Bobcat loader or mini excavator.

We provide a comprehensive boulder installation proposal that describes the boulders selected, the size of the boulders, and the cost to install them.  

Frequently Asked Questions

How much does a landscape design cost?

Designconsultations are free. Pool designs—and pool designs that include landscape—aretypically free. Stand-alone landscape designs may incur a nominal design feebased on scope. While landscape design fees can catch clients off guard, theyare critical to making sure the plan is buildable, bid properly, and that the crewsknow what to install. These highly detailed plans are also used for permitting,engineering (when required), and HOA and DRC submittals.

Can you help with pool and spa designs?

Yes— we specialize in turnkey landscape and pool design-build, with one point ofcontact for design and one for construction. Our team integrates pools, spas,and patios into a cohesive plan that looks intentional. Planning the entireproject from the beginning makes sure nothing is overlooked, installation isdone in the most efficient sequence, and, if the project is phased, rework islimited.

How long does the design process take?

Landscapedesigns typically take 2–4 weeks; pool designs can be completed in about fivebusiness days. While most people view the pool as the more complicated element,the detail in the landscape plan is what ties the entire project togethercohesively, and why it takes more time.

What happens if I want to make a revision?

Revisions are a normal part of the design process. Many times, what sounds good in conversation has a much different feel on paper. This is why the design process is so important to a successful project.

What happens after the design?

Revisions are a normal part of the design process. Many times, what sounds good in conversation has a much different feel on paper. This is why the design process is so important to a successful project.

What happens after the design?

Onceapproved, your design moves to estimating. We prepare a professional line-itemproposal, review it with you (there’s never pressure to decide on the spot),and incorporate any adjustments until the plan matches your vision and budget.

Frequently Asked Questions

What size boulders should I use?

Boulders are typically sized according to the area of placement. While a larger focal point boulder(s) may be placed in the front yard or the backyard, access isusually the determining factor. Court yards with limited access and planter beds usually utilize smaller boulders.

Boulder ssalvaged from the job site are free (except for the labor cost to salvage them) and the most economical way to proceed, but is not always a viable option. Boulders purchased from a supplier are priced by the total weight. Boulders can be purchased in bulk, by the truck load (with miscellaneous sizes), or hand selected.

Will berms block my views?

No. Berms are designed to add an elevation change, create visual interest, and are typically 12” to 18” high.

Can swales prevent erosion and water from entering my property?

Residential swales are a decorative and functional feature used in landscapes and can direct water away from the property. They mitigate erosion and assist in directing water flow away from the home. Properties that have a significant erosion or flooding problem should contact a hydrologist or engineer.  

How long does installation take?

It depends on the number of boulders, their size, access to the placement area and equipment required. In new construction projects, boulders are often placed early in the building process when there is good access and equipment can be used. When placed at existing homes, boulders are usually moved with a boulder dolly or wheelbarrow due to space limitations.
