Retaining walls in Parkland: what to know
Pierce County’s retaining wall bulletin exempts a wall not over 4 feet tall, read from the footing’s underside to the wall’s crest, unless a surcharge lies within a 45-degree angle of the footing. Walls under 2 feet are exempt from permits. Walls over 4 feet without a surcharge need one, and walls carrying a surcharge over 2 feet need one as well.
The county’s wall FAQ is stricter on loads, saying a wall supporting a surcharge always needs a permit. The two county documents do not agree on short walls with a load, so we ask the Development Center which rule governs before a loaded wall under 2 feet is built. Critical area status is checked before the footing is staked, since county guidance on driveways names critical areas as a possible permit trigger.
Permits and rules in Parkland
We measure the footing-to-top height on the section, and we confirm any surcharge with the Development Center before the wall is priced. We check whether the surcharge lies inside the 45-degree zone, and we verify whether the wall holds back a load from a driveway or structure above it.
Rules change and vary by parcel, so we confirm the current requirements with the city before we start.
How we approach it
- Read the height from the footing’s underside to the crest
- Mark any surcharge that falls inside the 45-degree zone
- Ask the Development Center which wall rule governs, in writing
- Route wall drainage to an outlet kept off the neighbor’s lot

Questions from Parkland homeowners
Does a Parkland retaining wall over four feet need a county permit?
Yes. The county bulletin requires a permit for a wall over 4 feet, with or without a surcharge. We take the height reading from the footing’s underside to the wall’s crest, then confirm it with the Development Center before the scope is written.
Does a short Parkland wall with a load behind it still need a permit?
It may. The bulletin exempts a surcharged wall up to 2 feet, while the county’s wall FAQ says a surcharged wall always needs a permit. Because those two county sources differ, we ask which one applies before a loaded short wall is built.
Where should water behind a Parkland retaining wall drain?
To an outlet on the parcel that does not push water onto a neighbor. We fix the outlet on the site plan before footing work begins, and we check that it stays clear of the road and any stormwater facility.
