Street Tree Planting:
Yes—but only on planting strips 12 feet or wider. If planting a street tree, you must be approved for a permit.
The classic Pacific Northwest native evergreen conifer. The Douglas fir is known for its noble, upright growth and lush needles, which form a beautiful downward sweeping canopy. The tree needs plenty of room to grow upward, making it an excellent yard tree.
Short, deep green needles grow around all sides of the twigs for a fuzzy, full appearance. Sticky, red buds at twig ends harbor pale green new growth and remain after buds burst.
Bright red new cones are upright, soft and frilly, ageing to pendulous brown cones.
Mature cones are a soft brown color and hang downward from branches, sporting three-pronged seeds protruding from scales.
Prefers moist, rich and loamy soils and wet conditions. Will fail in dry or drought prone areas. Needs full to partial sun and plenty of room to grow.
Generally very resistant to disease; can be prone to Douglas fir bark beetles, cankers, leaf and twig blights.

- 3 ½ feet back from the face of the curb
- 5 feet from underground utility lines
