Segmental Retaining Wall Construction Lake Oswego
Segmental retaining walls are a top choice for Lake Oswego homeowners due to their strength, flexibility, and cost-effective design. Constructed from interlocking concrete blocks, segmental walls are pre-engineered and can be built to meet the specific needs of each property, whether it’s accommodating a particular height, managing soil pressure on slopes, or supporting surcharge loads from nearby driveways or structures. This pre-engineering advantage allows segmental walls to be built to spec without the need for complex and costly on-site engineering, providing a stable, durable structure at a more efficient cost.
Segmental retaining walls are also highly versatile in design, available in a wide range of colors and textures to suit any aesthetic preference. Whether your style leans toward a sleek, modern look or a natural, stone-inspired finish, segmental walls offer options that seamlessly blend with the landscape and complement the architectural style of homes in Forest Highlands, Lakeview-Summit, Evergreen, Palisades, and Westridge.
Another benefit of segmental walls is their environmentally friendly design. The mortar-free, dry-stacked structure allows water to pass through, promoting natural drainage and reducing water buildup. For Lake Oswego homeowners, this combination of functionality, customizability, and engineering efficiency makes segmental retaining walls a practical and visually appealing solution for managing slopes, preventing erosion, and creating usable outdoor spaces.
Retaining Wall Permits in Lake Oswego, OR
In Lake Oswego, certain retaining wall projects require permits to ensure they meet safety and engineering standards. If you're considering building a retaining wall over four feet high, measured from the bottom of the footing to the top of the wall, a permit will likely be required. Additionally, if the retaining wall is affected by the weight of nearby structures, such as a driveway or building it will need to meet specific engineering requirements and obtain proper permitting.
Other installations, like incorporating stairs that exceeds 2.6 feet in height into a retaining wall, also require a permit to ensure stability and safe usage. White Oak Landscapes is familiar with the permit process in Lake Oswego and can assist you with designing and building a retaining wall that complies with local regulations, so your project is both safe and visually appealing.
At White Oak Landscapes we are familiar with the process in Lake Oswego and if you need a retaining wall that exceeds the four foot height limitation, we'll be able to help you secure the proper permits and build your retaining wall for you.
Proper Drainage For Your Retaining Wall
We are often contacted by potential customers who have an existing retaining wall that has failed, it’s either a rotting timber wall, falling down blocks, bulging, or collapsing. One of the most common reasons for retaining wall failure is that the original wall was built with poor drainage in place. Retaining walls are designed to hold back earth from erosion. This also makes them excellent at holding back water too. The water that builds up behind a retaining wall is referred to in the industry as “hydrostatic pressure” and the external force of the soil or fill held behind your retaining wall coupled with the weight of the water held behind it is often enough to seriously compromise the integrity of your wall which can lead to failures such as bulging and even a total collapse.
Any well-built retaining wall must incorporate good drainage if it’s going to last. Depending on the type of material being used to build your retaining wall there are a variety of ways to integrate sufficient drainage such as lateral drains, french drains, weeping drains, blanket drains and also the use of very granular soil or fill behind the wall can also help to disperse rather than hold the water.
What Is A Retaining Wall Surcharge?
A "surcharge" in the context of a retaining wall refers to any additional weight placed on or behind the wall, beyond just the soil it's holding. For instance, if you're constructing a retaining wall to support a parking area for a boat or RV, the weight of these vehicles must be factored into the wall’s design to prevent failure.
If your retaining wall will experience a surcharge, it must be engineered to handle this extra load. This includes walls with tiered sections, fences on top, or any other structures adding weight.
To reinforce walls facing surcharges, geo-grid is commonly used. Geo-grid strengthens the wall by anchoring it to the ground behind, distributing the load more evenly, and preventing collapse or buckling. Proper installation of geo-grid when required ensures your retaining wall is robust and capable of withstanding added pressure over time.
What Materials Do We Use For Retaining Walls?
There are many different materials to build your retaining wall out of. Below are some of the more popular materials we use in the Lake Oswego area because of their durability and availability.
- Segmental block retaining walls
- Timber retaining walls
- Fieldstone retaining walls
- Natural stone retaining walls
- Large boulder retaining walls
- Concrete block retaining walls
How Our Retaining Wall Construction Process Works
When building a retaining wall on your property that is designed to hold back soil and earth from erosion there is very little margin for error so we follow a specific process to determine how the wall should be built from a structural stand point. There are many pre-engineered systems (segmental retaining walls) we can use that can eliminate the need for detailed building plans so long as the wall is installed to manufacturer specifications.
Here's What We Do:
-
- We start with our initial consultation.
- We determine how many linear feet of retaining wall you need.
- We determine the height of the wall and if a building permit or engineer will be required.
- We take into account any surcharges (weight) the wall might be exposed to.
- We take into account excavation for a proper base and proper drainage systems.
- We consult with you on the materials you’d like your retaining built with.
- We’ll provide you with an accurate written estimate for the work.
The amount of work required to build a retaining wall can vary widely from project to project. The slope of your property, the amount of earth your retaining wall must hold back and the overall accessibility of your property will all contribute to the final cost. We’ll be able to offer you an accurate estimate only after a site visit.

How Much Does A Retaining Wall Cost In Lake Oswego?

Smaller Garden Walls
$3000 - $5000
This would be for a small garden wall (under 2 feet high) to surround a small garden or to surround a small landscaping bed.
Medium Sized Walls
$10,000 - $25,000
This would be for a medium sized wall up to 4 feet high. Installed with drainage and geo-grid so it lasts.

Lake Oswego Retaining Wall Replacement Or Repair
We specialize in rebuilding retaining walls that have failed and/or collapsed.
Retaining Wall Repairs in Lake Oswego
It's pretty common for us to get called out to repair an existing retaining wall that has collapsed or failed in some way. This could be an old wood retaining wall that is rotting away or a block wall that is bulging or on the verge of collapse if it has not collapsed already due to poor construction.
The bad news is that typically we can't really "repair" existing retaining walls. The wall has usually failed for a reason and that reason is typically poor construction, poor choice of materials, or other factors. When a wall has failed the best course of action is to usually tear it out completely, re-excavate the area, and then replace the wall properly. This has proven to be the more cost effective option in most situations.
Retaining Wall Replacement & Rebuilding Failed Retaining Walls
Older retaining walls, especially those built with landscape or railroad ties, can deteriorate over time, leading to instability and safety issues. In Lake Oswego neighborhoods with older homes, such as First Addition, Old Town, McVey-South Shore, Lakewood, and Hallinan, this is a common concern. If your retaining wall is showing signs of failure, White Oak Landscapes provides complete replacement services to address these issues.
We specialize in safely removing aging structures and replacing them with more durable, modern options, including segmental retaining wall blocks, natural stone, or treated timber. Our solutions are designed to offer long-lasting stability, enhancing both soil retention and curb appeal for your Lake Oswego property.
What Our Clients Say...
We strive for 100% customer satisfaction through prompt communication and following through on our promises
The White Oak crew are made up of really exceptional people. I had the great joy of working for them for a few years, and really got to experience what it’s like to work with attentive, creative and kind people who strive to do solid work. The creativity, quality of work and professionalism that White Oak has cultivated in their team I think really elevates their services beyond what most landscaping companies out their can provide. If you go with this company, you’ll not only be provided with amazing landscaping care from fine-gardening and construction experts, but you’ll also be working with true collaborators who actively listen to your needs with great humor and kindness. Many years after moving on, this company still stands out as an amazing work experience for me due to those qualities. Whatever your garden goals are, White Oak is a great example of a company that helps you meet them with collaboration, outstanding professionalism, and expertise.
I recently enlisted White Oak Landscape to enhance my yard as part of the preparation to sell my home in Beaverton, upon recommendation from my real estate agent. I was thoroughly impressed with their prompt, professional service and attention to detail. The team transformed the yard quickly and efficiently, creating a clean, polished look that significantly enhanced the property’s appeal. Their pricing was fair and competitive, reflecting the quality of their work. I highly recommend White Oak Landscape to anyone seeking reliable, high-quality landscaping services.
We are so grateful for all the hard work done by Taylor and McKinley to provide us a future sight blocker between our house and the neighbor's deck. They were very efficient in planting the 6 arborvitae including checking and adjusting depth of the holes and adding fertilizer to ensure a good start. Max worked within our time frames and kept us looped in on what day they would be arriving. I highly recommend White Oak for any of your landscape, etc needs 😊.
We’ve been using White Oak for years at our home in Oregon City. They’ve helped us design and construct some very special and intricate landscapes, exceeding our expectations. We enjoy working with Max and Kate and all the rest of their crew immensely.
We had a great experience with Max & the White Oak team! They listened carefully to what we wanted to accomplish, right-sized the solution to the problem (in our case, planting a front yard but not adding a retaining wall), brought a lot of knowledge to plant selection, and left the yard looking fantastic. We'll work with them again!
We love our landscaping by White Oak Landscapes! They were easy to work with — responsive and very considerate. They adapted their design for our yard based on our preferences (low maintenance) and constraints (budget), and provided helpful advice on what plants work best for our yard and how we might best care for them. We’ve received numerous compliments from our friends and neighbors on our front yard landscaping and would recommend White Oak to anyone.
Amazing people and built the most incredible landscape and water feature / natural swimming pond.
Sixteen-year-old pressure treated garden steps were failing and we were looking to get them replaced with the same thing. Instead, White Oak Landscaping suggested a better material that looks gorgeous. Once we got on the schedule, Max and Kate arrived and within hours we had a beautiful set of steps to our vegetable garden. A list has been drawn up for future projects and we hope to be able to collaborate with them again.
The White Oak team has been our go-to landscaper for many years. We have always been very happy with their services.
Very nice people to work with. They were very conscientious about our existing lawn and plantings. Even though they needed to do a little digging around the repair areas, I could hardly tell it was disturbed. I love the way the sprinkler work and cover the lawn area now. It’s never looked better! Thanks!!
Max responded to my sprinkler repair request promptly and arrived exactly when he promised. He fixed the problem perfectly and even did a follow up call to verify that the system was working well. I highly recommend White Oaks Landscapes!
White Oak took my very utilitarian needs/ideas and created a work of art! When I step outside I feel like I’m out in nature, not in a suburban backyard. Max and Kate and their whole crew were a pleasure to work with.
Would highly recommend working with Max and his team!
After hours and hours trying to figure out why one of my irrigation zones wasn't putting out enough pressure, I called Max at White Oak. Wow, 2 hours later not only had he isolated the issue and fixed it, they replaced my old heads with new ones, increasing the coverage over my lawn. Most important for me, was his description of all the other yard work they offer. Trimming, edging, mowing, fertilizing, weeding......on and on. Thanks so much, I will be using them into the future. Highly recommended.
We were so happy to find this great landscaper. Good communication and nice to work with. We wanted some work done on our overgrown front yard and mentioned another project. They gave good suggestions and grouped it all together into one fairly priced job. They squeezed us into their schedule and did the work in one day. We were so happy we immediately requested another job, which they did the following week. The gravel settled and was a little low, but they had no issue topping it off and smoothing it out, which they had anticipated needing to do. We will definitely continue to use them for all our landscaping needs. Thanks for being so great to work with!
WOW!!! I got an early Christmas present. Taylor and Noah prepared my gardens for winter. I had not been able to weed 2 of them for over a year due to some health issues. They did a super clean up job. Will definitely use them next Spring to replant one or two of the gardens. Thanks for making my day!!!
We had White Oak develop a full front yard landscape for us, and Max and Kate were really responsive to both our landscape needs and our budget. The work was done very quickly and there was never any question about what things were going to cost. Looking forward to doing more work with them in the spring!
What a great and professional team. I’ll be recommending grandiflora to all my neighbors.
Max and his team greatly improve the landscaping around our home in NW Portland in preparation for listing it for sale. From a design perspective, he had a wonderful strategy of where to focus on a large property to maximize value. The installation and irrigation was done correctly and without issues. The new gardens showed really well, were easy to maintain during the sales period, and we more than recouped our landscaping investment with Grandiflora Gardens.
I’ve never seen such professional and aesthetically minded landscapers. Lex and Zach knew their equipment (and used it SO efficiently!) that I could trust their work at an extremely high comfort level. Our job was not done as early as expected, but it was because of a very wet spring and our location/soil type. If I had the money, I’d hire this company for all my landscaping needs. They suggested good options for situations, and let me choose the option I liked, even when it wasn’t their favorite. Great company, and incredible staff.
Max not only gave me the most reasonable bid for the job, but he did great work and returned as soon as the system needed some tweaking. Outstanding customer service!
I had a great experience with Max from Earth, Water and Wood and would highly recommend hiring them. Max was professional, prompt and incredibly knowledgeable. I hired him to help out with a broken sprinkler head. He was able to fix the problem quickly and then did a full review of our sprinkler system and made some recommendations and changes to improve our system's efficiency and cut down our water usage costs. I highly recommend hiring Earth, Water and Wood.
Max and his crew are great! We've been working together for about 8 years now and my garden is a testament to his knowledge about plants and trees. Everything is thriving! He's easy to schedule with, he and crew are friendly, knowledgable people, and I feel very comfortable having them work around my house. I highly recommend them!
Max, the owner of earth water and wood has been absolutely fantastic with communication and did an amazing job with Lighting in my front yard. I highly recommend and will be using his services in the future for all other properties that need landscape care or lighting needs.
Our HOA property (River Royal Terrace) is fortunate to have found Earth, Water & Wood to rehab and care for our gardens and lawn. Max, owner, has been proactive in designing and carrying out his vision. His crew is exceedingly friendly and knowledgeable. We look forward to Spring's beauty and continuing this relationship. Thank you EWW!
I highly recommend Earth, Water & Wood. I had some difficulty finding someone who would take care of basic mowing for my lawn in Milwaukie at a reasonable price and I finally found it with these guys. They do a great job at mowing but not scaring my lawn and have great crews that come to do the work. I will definitely follow through and use them again next spring when lawn season starts up again.
