The Stillaguamish sits on the north edge of town, and a lot of the yards along the valley floor are old river ground: fertile when it drains, and a slick gray clay when it does not. Winter rain piles up against houses that back toward the Centennial Trail and the river parks, and the lawn stays soft long after the street looks dry. Flat clay yards need surfaces that shed and pipes that leave. A hardscape plan made of walls is solving a hillside you do not have.

Floors and drains, not tall walls
We tie the walk, the patio, and the downspouts into one grade. Beds are raised just enough to get roots out of the soup, with a rock or block edge that has a drain. Gravel takes the side path where pavers would be wasted money.
The test is January. If the drawing only looks good in July, we redraw it.
The ground in Arlington
Arlington is a valley town, not a hillside suburb. Lots near the farmland and the trail are often open to the west wind and sit on clay that holds water. After a wet week the soil smears under a boot and the moss moves into any thin spot in the grass. Houses closer to the river have a second problem: the ground is low, so a downspout that just dumps at the foundation has nowhere useful to send the water.
We plan work around that. Drainage goes in before we talk about a patio or a new lawn. Native plantings that actually belong on this floodplain — vine maple, salmonberry, and other understory that can take wet feet — do better than a plant list copied from a drier lot. Gravel paths and low rock work fit the rural edges of town without pretending the soil is something it is not.
How we do the work
Hardscape is the permanent part of the yard: the floors you walk, the walls that hold soil, the steps between them. We design it around how water moves and how you move. A pretty patio with a stair that lands in the low spot is a collection of pieces, not a yard.
We would rather build less and have it drain than fill a lot with surfaces that all tip the wrong way. Materials stay limited. One stone, one wall type, so the place looks finished instead of like a showroom.
What we look at first
- The route from the door to the gate, the drive, and the part of the yard you use
- Every place water stands now
- Slopes that need a step or a wall before they need a plant
- What has to stay: trees, fences, the neighbor’s grade
One material, used honestly
Pavers, a wall block or a rock, and gravel. That is usually enough. Mixing flagstone, brick, river rock, and a second paver line makes a small yard loud and gives water more joints to exploit.
Steps
Even risers, a tread you can put a whole foot on, and a surface that is not slick when it is wet. Landscape steps are where people fall. We build them like we will use them in the dark, in January.
The grade drawing
We can usually do this on site without a formal plan set, and we still mark elevations. Water is a number, not a feeling. If the fall is not there, we add a drain or we change the floor. We do not squint and hope.
