Monroe sits on the Skykomish, with the fairgrounds on the edge of town. River-bottom ground stays wet, and a yard built as if the water table were low will heave, puddle, or grow moss until someone deals with the water. Board fencing in the low ground traps debris and can be flattened. We fence the yard you use up by the house. We do not dike the bottom of the lot with cedar.

A fence is not a flood wall
Posts on the bench are a normal wet-soil set. If a run has to cross ground that floods, we talk about a style that lets water through, or about stopping the fence short. Replacing a flattened fence every other spring is not a warranty issue. It is the wrong place for boards.
Gates near a shop or a drive get the heavy hinges. River-town properties tend to have those working gates, and they sag first.
The ground in Monroe
We see two kinds of lots. In town, smaller yards with the usual compacted soil and a lawn that has to look fine for most of the year. Closer to the river and the low ground, soils that remember high water. Gravel and drains belong there. A finished bark bed in a spot that floods is mulch in the neighbor’s fence line by spring.
The fair is part of the calendar. People want yards cleaned up and hedges cut back before the traffic and the guests, and they want storm debris gone after the first big fall wind. Trees on these lots — including the old fruit trees — need pruning that opens them up, not a topping that makes them dangerous. Native plantings along the wet edges do the work a lawn cannot.
How we do the work
A fence in this county fails at the post. Wood rots where it meets wet soil, and a post set in a soft hole leans when the clay shifts. We set posts deep, we crown the concrete or the rock so water does not pool on the wood, and we keep the bottom of a board fence off the ground so it is not wicking mud.
Cedar for the boards, pressure-treated or steel where it touches the soil. We do not bury untreated lumber. Gates are built as gates, with a brace, not as a short panel that sags by August.
What we look at first
- The property line, before we dig
- Slope, and whether the fence should step or rack
- Who keeps the good side, and where the gates need to swing
- Sprinklers and the neighbor’s grade
Gates
A diagonal brace in the right direction, hinges that can carry the weight, and a latch you can open with one hand. The gate post is bigger or deeper than the line posts. A sagging gate is a build problem, and it shows up fast.
How long cedar lasts
A well-set cedar fence in this rain is often in the fifteen to twenty year range, longer if the bottom stays dry and you stain it before it goes gray and split. The posts outlive a careless bottom board. We build so you can replace boards later without replacing the line.
Stepped or racked
Stepped panels on a real slope, so the boards stay plumb and the gaps stay even. Racking a flat panel down a hill twists the frame. We pick the method from the grade, not from a photo.
