Building New Retaining Walls in Shoreline, Washington
At Greenleaf Landscaping & Construction, we build structurally sound, visually appealing retaining walls designed to solve elevation and drainage issues common across Shoreline and the surrounding region. Whether you’re dealing with a sloped backyard, erosion concerns, or the need to carve out flat, usable space, we offer solutions built to last.
We follow manufacturer specifications for the products we install, ensuring proper base prep, compaction, and drainage. From tiered garden walls to poolside retaining walls and corner solutions, every project is customized to meet site conditions and local requirements.
Do You Need a Permit for a Retaining Wall in Shoreline?
In most Shoreline-area municipalities, retaining walls under 4 feet tall typically don’t require a permit. However, walls over 4 feet, or those supporting additional weight (known as a surcharge)—such as driveways, fencing, or structures—often require both a permit and engineering approval under Washington building codes.
We assess all project details during your consultation and can coordinate with licensed engineers when required. We’ll also handle the permit process for you if needed.
Why Proper Drainage Matters
A large percentage of failed retaining walls we replace in the Shoreline area were built without adequate drainage. Heavy clay soils common in this region hold water, which increases hydrostatic pressure behind the wall. Without drainage, this pressure leads to bowing, cracking, or full collapse.
That’s why every retaining wall we build includes appropriate drainage—such as weeping tile, perforated pipe, gravel backfill, and filter fabric—to protect the structure and extend its lifespan.
What Is a Retaining Wall Surcharge?
A surcharge refers to any added weight or load above or behind your wall—like a parked vehicle, hot tub, fence, or terraced landscaping. These loads significantly increase the pressure on the wall and require reinforcement.
We account for these loads by using methods like geo-grid reinforcement, which locks the wall into the surrounding soil to resist movement. If your wall has a surcharge, proper design and materials are critical.
Common Materials We Use To Build Retaining Walls
We offer a variety of retaining wall options to suit both structural needs and aesthetic preferences:
-
- Segmental block retaining walls (ideal for most residential applications)
- Natural stone retaining walls (great for rustic or high-end landscapes)
- Boulder walls (excellent for larger slopes and a natural look)

How Much Do Retaining Walls Cost To Build?
Retaining walls can vary in price depending on the length, height, and the materials chosen. Larger walls may need to be engineered which can add to the cost.
Smaller Garden Walls
$3,000 - $5,000
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
$5,000 - $10,000
This would be for a medium sized wall up to 4 feet high. Installed with drainage and geo-grid so it lasts.
Large Retaining Walls
$10,000+
This would be a ballpark cost for a very large or tiered retaining wall or multiple wall with courses that are 4 feet or higher
Retaining Wall Projects Can Include
A beautiful retaining wall isn't just for looks. They have an important job to do. Whether we're building a brand new retaining wall or replacing an existing retaining wall that has failed, there are a number of things we do.
Is Your Retaining Wall Failing, Leaning, Or Collapsing?
Retaining Wall Repairs in Shoreline, Washington
In the Shoreline area, we’re frequently contacted by homeowners dealing with retaining walls that have failed—whether it’s an old timber wall that’s rotting, or a block wall that’s leaning, bulging, or collapsing. Washington’s clay-heavy soils, freeze-thaw cycles, and poor drainage can all contribute to structural failure—especially when the wall wasn’t built to code or with proper materials.
At Greenleaf Landscaping & Construction, we don’t just patch up problem walls—we rebuild them the right way. In most cases, a failing retaining wall is a sign of poor base prep, inadequate drainage, or insufficient reinforcement. Instead of temporary repairs, we typically recommend full replacement to ensure long-term stability and safety.
Rebuilding Failing Retaining Walls the Right Way
If your retaining wall has already failed or is clearly showing signs of structural issues, we can help. Our process includes:
-
- Safe demolition and removal of the old wall
- Re-excavation to prepare a proper foundation
- Installation of crushed stone base, drainage systems, and geo-grid reinforcement where needed
- Rebuilding with modern materials like segmental block, natural stone, or boulders, depending on your preferences and property needs
We specialize in replacing failed walls with code-compliant, professionally engineered structures that will perform for years—even under pressure from poor soil, water buildup, or added weight (surcharges).
If you live in Shoreline, Kettering, Bellbrook, Springboro, Xenia, or nearby areas, and your retaining wall is leaning, cracked, or failing—contact Greenleaf Landscaping & Construction for a consultation and long-term solution.
