Retaining Walls in Tumwater, WA
Most of Tumwater is flat prairie. The exceptions are steep.
Where walls matter in Tumwater
- Mapped slopes. The Deschutes River bluffs, Tumwater Hill, Bush Mountain and the hills west of Black Lake Boulevard are mapped as steep-slope or landslide areas. Tumwater code looks closely at slopes of 40% or more with 10+ feet of relief.
- Soft ground. Along Percival Creek there are peat and muck soils that settle. Walls there need a careful look first.

Tumwater wall FAQ
I'm on Tumwater Hill. Can you build a wall?
We'll look at the slope first. Steep ground can bring extra review, and we'll tell you plainly what it needs.
Do walls need drainage?
Yes. Without it, wet-season water builds pressure behind the wall.
Can you build near Percival Creek?
We'd look closely first. Peat and muck soils there settle, and that changes what a wall needs.
