Service Area · Sammamish, WA
Sammamish Plateau yards have a particular look - formal at the entry, native through the back, mature canopy framing views toward the lake or the foothills. Heritage trees over 22" DBH and landmark trees over 32" anchor most of the older plats, and the work here is preservation-first: keep the mature trees mature, keep the entry hedges hand-finished, manage the ornamentals on cycle.
The code backs all of that with real enforcement. Heritage and landmark protection is taken seriously here, and the retention math gets checked. We work inside it, and your yard stays beautiful.
Mature canopy, formal entries, and a code that protects both.

THE CODE
Sammamish protects its canopy in three tiers, and heritage and landmark trees face enhanced review. We handle the permit, the arborist documentation, and the replanting plan.
ON THE GROUND
From the entry drives to the lake-facing back yards, we know what's actually growing on plateau lots.
Douglas fir
dominant plateau canopy; watch for laminated root rot.
Western red cedar
older trees showing top dieback; most recoverable.
Bigleaf maple
defining hardwood canopy; summer branch drop applies.
English laurel, European hornbeam, boxwood
the formal entry palette.
Japanese maple
high-touch ornamentals in entry beds, kept on cycle.
Most of Sammamish runs 15 to 20 minutes from our East Renton shop.
