Gold Bar is a foothill town on the Skykomish. The river is the flood story, and the banks above it are rock and thin soil. Spring water comes down the cuts fast, and a lawn or a driveway that ignores that ends up as a channel. On a slope, pavers without a wall or a serious edge become a staircase that is slowly walking downhill.

A patio on a bench, a path that stays put
We build the flat. If that means a low wall first, the wall is part of the paver job, not an extra we mention later. The base is compacted rock, and the low side is restrained like it matters, because it is the side the whole field leans on.
Drives and paths in the foothills take water from above. We intercept that water so it is not running across the pavers every storm and pulling the joint sand to the bottom of the hill.
The ground in Gold Bar
Lots here are not the flat rectangles of Marysville. Driveways climb, yards step down toward the river or the highway, and the native ground is rocky enough that a shovel stops early. When the river runs high, low ground remembers it. We do not put a finished lawn or a bark bed in a spot that has carried water.
What works is straightforward: rock and retaining where the bank is moving, gravel on the steep drive, and a drain that has a real outlet instead of a hole filled with hope. Plantings stay rugged. A manicured hedge is a maintenance bill in a town that gets the mountain rain. Cleanup is often storm debris and alder coming in from the edge of the clearing.
How we do the work
The paver is the skin. The base is the job: excavated, built up in compacted rock, deep enough that this climate will not heave it into waves. We pitch the surface away from the house, we restrain the edges so the field cannot spread, and we sand the joints.
A paver patio set on a couple of inches of loose gravel over clay will look perfect in September and rock underfoot by March. We do not build that, even if the other bid did.
What we look at first
- How the water leaves the surface today
- Clay, fill, or roots under the area
- Edge restraint and where the field ends
- Whether the project is a walk, a patio, or a drive, because the base changes
Joint sand
Swept and settled, then checked. Polymeric sand has a place where ants and heavy rain empty the joints, and it has a failure mode if it is installed wet or left on the face. We use it when it helps, and we wash the haze off before we leave.
Edges
Plastic or metal restraint, spiked into the compacted base, then buried so you see paver, not a black strip. An edge against soil with no restraint is the row that opens up.
The base depth
Deeper for a drive than for a walk, and deeper on clay than the brochure drawn for a dry state. We compact in lifts. A single dumped pile of gravel, raked once, is not a base. You should not see waves after the first winter.
