Scotts Valley Retaining Walls

When you are choosing material to build a retaining wall in your yard or garden, there are many different choices on the market.

Wood retaining walls, like the ones we just finished in the picture to the right, are low cost and very sturdy. 


For this retaining wall job in Scotts Valley, just outside of Santa Cruz, we used 6x6 posts with 2x12 boards. When building a wooden retaining wall make sure to always use pressure treated lumber. 

Drainage is also a crucial part in the design and installation of a wood, or any type of, retaining wall construction.


Without drainage, the retaining wall could fail due to hydro-static pressure. Hydro-static pressure is caused by over saturation of water in the soils behind the retaining wall.


A French Drain in the best way to ensure proper drainage behind your wall. A French Drain is constructed using a perforated pipe behind the wall, at the base. The pipe is wrapped in filter fabric and back-filled with drain rock. Although you can't see it, we installed a French Drain behind each retaining wall in the construction of this project.

Another drainage system that we use in our retaining wall construction is called EZ-flow. This system uses perforated pipe wrapped in styrofoam and geo-textile fabric. It can hold more water than a traditional French Drain, and it much easier to install. We used the EZ-flow system on the wood retaining walls we just finished. EZ-flow is great for retaining wall projects with difficult access.
