The trees of Bethany

ZIP 97229. Unincorporated Washington County, with Portland mailing addresses.

In August 2026 the Oregon Department of Forestry confirmed emerald ash borer at Bethany Lake Park. For a community with ash along its greenways and planted ash on some of its streets, that makes tree care here more urgent than it was a year ago.

Start with the ash. Native Oregon ash grows in the wet ground along Rock Creek and its tributaries, and green and white ash cultivars were planted as street and yard trees in the 1990s. Emerald ash borer kills nearly all untreated ash within a few years of arriving. The choice for each tree is treatment by a licensed applicator, or removal while the wood is still sound.

Most of Bethany's other trees are planted and young. Street trees in the 1990s neighborhoods are now large enough to lift sidewalks and crowd houses. In North Bethany they are a few years old, the age at which a few small pruning cuts prevent the weak forks that split twenty years later.

Between the subdivisions, builders kept strips of native fir, cedar and maple as open space. Nearly all of it belongs to homeowners associations, and nearly all of it borders somebody's back fence.

What we are usually called for in Bethany

Ash assessment, treatment referral and removal

We identify ash, tell you which trees are worth treating, and remove the ones that are not. Ash wood stays inside the state's quarantine area. Tree removal.

Structural pruning of young trees

A few small cuts on trees under ten years old to set one main trunk and well-spaced limbs. It is the most useful pruning a tree ever gets. Tree trimming and maintenance.

Common-area tree work for associations

Inspections and removals along open-space edges, with written findings a board can act on and photos for the record. Tree removal.

Stumps in small yards

Tight side yards, close utilities and irrigation everywhere. The 811 locate and a walk-through with the owner come before any grinding. Stump grinding.

Around Bethany

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

Bethany Lake Park

The park at the end of the Rock Creek greenway is where emerald ash borer was confirmed. Walk the trail and look at the ash: thinning from the top, bark stripped by woodpeckers, and sprouts on the trunk are the signs to compare with your own trees.

Bethany Village

The center of the 1990s community. Its street and parking lot trees are reaching the size where roots and paving collide. Trees on commercial and apartment sites were required by the county's approval of the development.

North Bethany

The newest streets have the youngest trees, along with stormwater swales and planted corridors that are regulated. It is the right moment for structural pruning, and the wrong place to assume a planted strip is yours to clear.

Kaiser Woods and the Springville edge

At Bethany's north edge the subdivisions meet farmland and remnant forest. Yards here face open ground to the north and east, and take more winter wind than the streets inside.

Which tree rules apply in Bethany

Bethany is unincorporated, with a Portland mailing address. Neither Portland's tree code nor Beaverton's applies here.

In unincorporated Washington County

No city tree code applies here, even with a Beaverton or Portland mailing address. The county generally leaves trees on a developed home lot to the owner, with two big exceptions: mapped Significant Natural Resource areas, and the vegetated corridors along creeks and wetlands that Clean Water Services regulates. Cutting inside either can need review, even for a dead tree.

Trees along the road are generally the adjoining owner's responsibility, and a county right-of-way permit is needed when planting or removal affects traffic. Many subdivisions add a layer of their own, with covenants and common-area trees that need the homeowners association's approval. For neighbor disagreements over trees, the county points residents to free community mediation.

Specific to Bethany

Two things shape tree work in Bethany more than the county does. First, nearly every home is in a homeowners association with covenants that cover street trees and common areas. Second, the state's emerald ash borer quarantine covers all of Washington County, so ash wood, chips and firewood must not leave the quarantine area. The creek corridors are regulated by Clean Water Services.

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 Bethany

Is emerald ash borer in Bethany?

Yes. The Oregon Department of Forestry confirmed it at Bethany Lake Park in August 2026. If you have an ash, have it looked at now. Healthy trees can be protected with treatment. Declining ones get brittle and are safer to remove early.

Who is responsible for the street tree in front of my Bethany home?

In unincorporated county the adjoining owner is generally responsible, and most Bethany associations add requirements of their own about species, pruning and replacement. Check your covenants before removing or replacing one.

The trees behind my fence belong to the HOA. What if one looks dangerous?

Tell the board or the management company in writing, with photos, and keep a copy. An association that has been told about a hazard is responsible for acting on it. We can provide a written assessment if they ask for one.

When should a young tree first be pruned?

Two to three years after planting, once it is established, and then every few years until it is about ten. The goal is one main trunk and well-spaced limbs. Small cuts now prevent large, risky ones later.

Do you give free estimates in Bethany?

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.
