Juanita runs downhill to Juanita Bay, one of the largest natural wetlands left on Lake Washington, and is cut through by Juanita Creek and its tributaries. That water is the reason Juanita is green, and the reason tree work here so often starts with a buffer check.
The main question: is the tree in a critical-area buffer?
Kirkland treats wetlands, streams and landslide hazard areas as critical areas, with buffers around them. If your tree is in one:
- the free Tree Removal Notification can’t be used
- removal needs a permit, and the tree must be a hazard or nuisance tree
- pruning needs written permission first (a “Critical Area Tree Pruning Request”)
- replanting is usually native species, and cut wood may be left as habitat
Lots backing onto Juanita Bay Park, Juanita Beach Park, the creek corridors and Forbes Creek are the most likely to have buffers. The Kirkland GIS browser shows them.
Juanita trees
| Tree | Where | Watch for |
|---|---|---|
| Black cottonwood | Creek and lake edges | Fast, tall, brittle; big limbs drop in wind |
| Red alder | Wet slopes and buffers | Short-lived; heart rot after 50–60 years |
| Douglas fir | Upper slopes | Root rot; windthrow on saturated soil |
| Western redcedar | Wet ground near streams | Top dieback in drought years |
| Willow | Wetland edges | Splitting, leaning toward water |
Working near water
- No stump grinding in a buffer without checking. Roots hold the stream bank.
- Debris stays out of the creek. Chips and sawdust are kept off the water.
- Access is often from the top of the lot, with pieces lowered or carried uphill.
- Winter work is wetter and slower; plan non-urgent buffer work for late summer.
Not in a buffer?
Many Juanita lots on the flatter streets aren’t, and the normal yearly allowance applies: 2, 3 or 4 trees per 12 months by lot size, with the free notification. The checker works it out.

(425) 000-0000Common questions
How do I know if my Juanita lot has a critical-area buffer?
Look up the parcel on the Kirkland GIS browser and turn on the critical areas layers, or call Planning and Building at 425-587-3600. Lots near Juanita Creek, Forbes Creek, Juanita Bay and steep slopes are the usual ones.
Can a dangerous tree in a stream buffer be removed?
Yes, as a hazard tree with a permit and an arborist report, or immediately if it's an imminent danger, reported within 7 days. Removal in a buffer usually comes with replanting, and wood may need to stay in the buffer as habitat.
Why are cottonwoods a problem in Juanita?
Black cottonwoods grow very fast along the creek and lake, reach great heights, and have brittle wood that drops large limbs. Near houses they are a frequent storm call.
