Tree Service in Skagit County, WA

The Skagit is the largest river flowing into Puget Sound, and it built most of the county it runs through. Whether your trees stand in river silt, on a rocky island headland or on a steep timbered slope forty miles upstream decides nearly everything about how they are going to fail.

Delta Silt Grows Trees Fast and Holds Them Poorly

The lower valley is river-laid silt and sand behind dikes, with groundwater sitting close to the surface for much of the year. That ground grows black cottonwood at a rate that surprises people from drier country. It also grows a tree that gets tall and heavy long before it gets strong.

Cottonwood is the most common failure call we get out of floodplain country anywhere in Washington, and the Skagit flats have as much of it as anywhere in the state. Brittle wood, decay pockets where old limbs shed, and a root plate anchored in ground that goes soft every wet December. The trees are worth having along the river and worth watching hard anywhere near a house, a shop or a road.

The Windbreaks Are Aging Out

Rows of poplar and cottonwood went in around farmsteads and field edges across the flats generations ago — planted tight, never thinned, then left alone. What they are now is a line of tall, top-heavy stems all leaning the same way over equipment sheds, greenhouses, irrigation lines and the county road.

Pulling one tree out of a row like that is a different job than pulling one out of a yard. There is no clean escape route, the stems on either side are just as compromised, and dropping them in the wrong order leaves the survivors worse off than before. It is also exactly the kind of multi-day scope that makes the drive north worth making.

Three Different Counties Wearing One Name

Out on Fidalgo Island around Anacortes the ground turns thin and rocky, the rainfall drops off in the Olympic shadow, and madrone and shore pine take over from fir and alder. That is saltwater bluff country, with wind off the water and bare rock inches down, and it wants an entirely different approach than the flats do.

Head the other direction — Sedro-Woolley, Lyman, Concrete, Rockport, Marblemount — and you climb into steep, wet, heavily timbered ground where hemlock and redcedar take over, the annual rainfall climbs sharply, and slope stability is a live question on a lot of parcels. Wet snow and saturated soil do more damage up there in a single winter than wind does out on the delta.

The valley itself works as a funnel. Cold air draining west through the Skagit gap in winter arrives hard and dry from the east, which is the opposite of the direction most of these trees have spent their lives learning to resist.

The rules follow those same divisions. Mount Vernon, Burlington, Anacortes and Sedro-Woolley each set their own, shoreline and critical-area rules apply along the river and the saltwater, and vegetation on or beside a levee may be the diking or drainage district decision rather than yours. All of it varies by parcel and changes over time, so confirm with your city or with the county before anyone quotes the work.
