The trees of Five Oaks

ZIP 97006. Inside Beaverton city limits, bordered by unincorporated Aloha, Tanasbourne and Oak Hills.

The area was built out between the 1970s and the 1990s, one subdivision at a time, on former farmland and second-growth forest. Builders kept clumps of native Douglas-fir and a few Oregon white oaks, then lined the new streets with whatever the nurseries were selling that decade.

That history explains the tree work. The street trees from the 1980s and 1990s are mostly red maple, sweetgum and ornamental pear. All three grow fast, all three lift sidewalks, and sweetgum and pear are the first trees to come apart in an ice storm because of their narrow, crowded forks.

The remnant firs are the other half of the story. A Douglas-fir that grew up inside a stand, then lost its neighbors to a cul-de-sac, is more exposed to wind than it was built for. Most are fine for decades. The ones to watch have thinning tops, fresh cracks in the soil at the base after a storm, or a neighboring fir that has already gone over.

Along Willow Creek and the low ground near it you also find Oregon ash, red alder and black cottonwood. With emerald ash borer confirmed in Beaverton and at Bethany Lake Park a few miles north, any ash here is worth having identified and looked at now.

What we are usually called for in Five Oaks

Street trees that have outgrown the strip

Sweetgums and maples in four-foot planting strips lift the sidewalk and hang low over the street. We raise and reduce them to the city's clearances. When one has to go, the permit and the replacement tree are settled first. Tree trimming and maintenance.

Backyard firs close to the house

Tall firs a few feet from a roof or a fence come down in sections on ropes. Often they don't need to come down at all, and deadwood removal and a little end-weight reduction is the better job. Tree removal.

Ice and wind breakage

Split pears, snapped sweetgum tops and hanging limbs after January ice or an east wind. We clear driveways first and come back for the rest. Emergency tree service.

Old stumps in small front yards

Stumps from street trees removed years ago, usually a few feet from the water meter and the cable line, which is why the 811 locate comes before the grinder. Stump grinding.

Around Five Oaks

Local landmarks, and what the trees around each one tell you about your own.

Willow Creek greenway

The boardwalks and wetlands along Willow Creek are a protected natural corridor. If your back fence faces the greenway, the trees along that edge are probably inside a regulated buffer, and even a dead one may need the city's sign-off before it is cut. Ash, alder and cottonwood dominate, and all three shed large limbs.

Waterhouse Trail and the power line corridor

The trail runs north to south under the transmission lines. Trees beside the corridor are kept short by the utility, not by homeowners, and anything tall enough to reach the wires is the utility's to deal with. Yards next to the corridor catch more wind than sheltered streets a block away.

Around Five Oaks Middle School

The streets off 173rd show the neighborhood's street tree history in one walk: forty-year-old sweetgums and maples with roots under the sidewalk, and younger replacements where the first generation has already come out.

Tualatin Hills Nature Park, just to the south

The park's fir, cedar, ash and oak forest is a good picture of what stood here before the houses. It is also a reminder that the big firs left in nearby yards are forest trees living alone, which is what makes wind their main risk.

Which tree rules apply in Five Oaks

Five Oaks and Triple Creek is inside the city, so Beaverton's code applies. Cross 185th or Walker Road in the wrong direction and you may be in unincorporated county, where it doesn't.

Inside Beaverton city limits

The tree between the sidewalk and the street is a street tree. You maintain it, and removing it takes a city permit and normally a replacement from the city's approved list. Cutting 20 percent or more of the crown or roots counts as removal. Street trees have to clear 8 feet over the sidewalk, 12 feet over the street and 14 feet over arterials, and topping them is prohibited.

Most ordinary backyard trees need no permit. The exceptions are the trees the development code protects: significant and historic trees, trees in significant groves and natural resource areas, and landscape or mitigation trees that were kept or planted as a condition of the subdivision. If your lot backs onto a greenway, a creek or a preserved grove, treat the trees along that edge as protected until the Planning Division (503-526-2420) says otherwise.

Specific to Five Oaks

Many of the fir groves that builders kept here were preserved as a condition of the subdivision, which makes them protected grove or landscape trees even though they stand in private backyards. Lots along Willow Creek add a natural resource buffer. Both are easy to check with the Planning Division before you plan a removal.

The permit checker gives a first answer in two questions, and the permit guide has the detail. We check every tree's status before a job is booked.

Tree service questions from Five Oaks

Do I need a permit to remove a street tree in Five Oaks?

Yes. A tree between the sidewalk and the street is in the public right-of-way, and Beaverton requires a permit to remove it and normally a replacement from the approved list. We settle the permit before the job goes on the calendar.

My lot backs onto the Willow Creek greenway. Can I cut trees along the back?

Check first. Creek and wetland buffers are regulated, and trees inside them are usually protected even when they stand on your side of the fence. The Planning Division can tell you where the buffer line runs on your lot.

Why do the pears and sweetgums on my street keep breaking?

Both grow many upright limbs from one point, with bark trapped in the forks. Ice and wet snow load every limb at once and the forks split. Reduction pruning before winter helps. Badly split trees are usually replaced.

Is my address in Beaverton or in the county?

Around 185th and Walker Road the boundary zigzags. Your property tax statement lists the City of Beaverton if you are inside it. If it doesn't, Washington County's rules apply instead, and the street tree permit described here does not.

Do you give free estimates in Five Oaks?

Yes. We walk the site, tell you what the tree needs, and put the scope in writing: what is cut, how it comes down, where the wood and chips go and whether the stump is included. Call (503) 386-0199 or send the form on this page.
