Concrete Retaining Walls in University Place, WA

Retaining walls in University Place: what to know

Steep terrain is why retaining walls are so common in University Place, and why the city has its own standards for them. A wall might hold back a cut for the driveway, carve a level yard out of a slope, or protect a house from soil above.

Water is the constant. Saturated soil is heavy, glacial till drains slowly, and a wall with no way to relieve that pressure will eventually lean. We detail the footing, steel, drain rock, and drain outlet as one system. Where there’s a slope above or below, we also look at the whole hillside, not just the wall, because the wall and the slope work as a system.

Permits and rules in University Place

University Place’s municipal code has its own retaining wall standards, including limits on wall height and setbacks, and it provides for emergency permits in some situations. The state code adds its own triggers: a wall taller than 4 feet from the bottom of the footing to the top, or one that carries a driveway or structure, generally needs a permit and engineered plans. Steep slopes and other critical areas can require a geotechnical report. We check the city’s rules and your parcel’s mapped hazards before we design or quote.

Rules change and vary by parcel, so we confirm the current requirements with the city before we start.

How we approach it

Review the city’s wall standards and your parcel’s mapped hazards first
Consider terraced walls where one tall wall would exceed limits
Coordinate engineering and permitting when they’re required
Build to the design with a drain, rock backfill, and a working outlet

Questions from University Place homeowners

Does University Place have its own retaining wall rules?

Yes. The city’s municipal code includes retaining wall standards, such as limits on height and setbacks, in addition to the state building code. We check them for your parcel before we design.

Can I build a tall retaining wall on a steep lot in University Place?

It depends on the height limits, setbacks, and slope conditions. Terraced walls are often a workable alternative to one tall wall.

My old retaining wall is failing. Can it be replaced in University Place?

Usually. We look at why it’s failing, which is often drainage, and design the replacement to fix that. A new wall may need a permit depending on its height and what it supports.
