The subdivisions around Salmon Creek went in through the 1990s and early 2000s, and the retaining walls that came with them were built to the minimum standard the project would accept. Many were timber; many block walls went in without proper drainage behind them. Both are now failing at roughly the same time across whole neighborhoods.
If your wall is leaning, bulging or shedding soil over the top, that is structural movement and it does not stop on its own. It accelerates, because every degree of lean lets more water in behind it. Rebuilt early it is a straightforward job; left until it fails it takes the fence, the patio or the driveway above it along with it.
We rebuild these with the drainage that should have been there originally, which is the entire reason the replacement will outlast the original by decades.
How we build it
- Compacted crushed rock footing on undisturbed soil
- Buried base course for stability
- Clean drain rock and filter fabric behind the full face
- Perforated drain pipe daylighted to a real outlet
- Geogrid soil reinforcement where the design requires it
- Honest guidance on when an engineer and permit are needed
A retaining wall is a structure, not decoration. It is holding back tons of saturated clay, and in this climate that clay is saturated for six months of the year. The walls that fail around here almost always fail for the same reason: nobody dealt with the water behind them.

Retaining Walls in Salmon Creek: questions we get
How tall can a retaining wall be without a permit?
The common threshold across Washington jurisdictions is about four feet, measured from the bottom of the footing to the top of the wall — but if the wall carries a surcharge such as a driveway, a slope or a structure above it, engineering is usually required at a lower height. Requirements differ between Clark County and individual cities, so always confirm with the building department that covers your address.
Why is my existing wall leaning?
Nine times out of ten it is water. If there is no drain rock and pipe behind the wall, saturated clay pushes against the back of it every winter and the wall slowly rotates forward. The other common causes are a footing set on soft or uncompacted soil and a missing buried base course. A leaning wall does not correct itself and gets more expensive the longer it sits.
Can you build a wall against my property line?
Often yes, but setbacks, easements and the drainage outlet all need checking first, and the excavation behind a wall usually needs more room than people expect. If the wall would affect a neighbor’s grade we will raise it before we quote.
