Tree service in Oak Hills, Oregon

Oak Hills was laid out in the mid-1960s as a complete community, with houses and townhomes arranged around shared greenways, a recreation center and a school. In 2013 it was listed on the National Register of Historic Places as a mid-century planned community, the first of its kind in Oregon to be recognized that way.

The trees of Oak Hills

ZIP 97006. Unincorporated Washington County, with a Beaverton mailing address.

The design put trees at the center. Native oaks and firs were kept where they stood, the commons were planted generously, and sixty years later the canopy is the neighborhood's most valuable feature and its biggest maintenance item.

The trees are all about the same age, which means they are all reaching the same stage together. The planted maples, sweetgums, birches and pines are mature to over-mature. Birches are dying of bronze birch borer, sweetgums break in ice, and pines planted close to houses have outgrown their spots.

The native trees are older still. The Oregon white oaks that gave the community its name and the Douglas-firs kept from the original woodland are the ones most worth careful work. Oaks in particular dislike summer irrigation and soil disturbance under their canopy, both of which are hard to avoid in a landscaped yard.

Because the greenways run behind most lots, a large share of the trees that shade Oak Hills homes stand on association land. That decides who pays attention to them, who approves work on them, and who is responsible if one fails.

What we are usually called for in Oak Hills

Pruning mature yard trees to the association's standards

Deadwood, clearance and reduction on sixty-year-old trees, done so the result fits the neighborhood's character. No topping and no lion-tailing. Tree trimming and maintenance.

Removing over-mature pines and birches

Dead and failing trees taken down in sections in small yards and courtyards, once the association has signed off. Tree removal.

Careful work on native oaks

Conservative deadwood removal and clearance on Oregon white oaks, and advice on what to change on the ground around them. Tree trimming and maintenance.

Stumps in townhome courtyards

Grinding where the only access is a gate or a path, using a compact machine, with utilities located first. Stump grinding.

Around Oak Hills

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

The commons and greenways

The shared open space behind the houses is the association's property, and so are its trees. If one overhangs your lot or looks unsafe, report it to the association in writing. You may not prune or remove it yourself.

Around Oak Hills Elementary

The school sits in the middle of the community beside the recreation center, surrounded by some of the original oaks and firs. It is the easiest place to see how large the neighborhood's native trees have become.

The townhome clusters

Attached homes share walls, courtyards and landscape strips. A tree in a courtyard can belong to one owner, to several, or to the townhome association, and it is worth finding out which before requesting an estimate.

The Sunset Highway edge

Homes along the south side back onto the highway corridor and its sound walls. Trees there screen noise and take the east wind that funnels along the highway in winter.

Which tree rules apply in Oak Hills

Oak Hills is unincorporated, so no city tree code applies. In practice the homeowners association is the rule-maker 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 Oak Hills

The National Register listing recognizes the community's design and does not by itself regulate what you do with a tree in your yard. The association's covenants and design guidelines do. They cover common-area trees entirely and can cover visible changes to private lots. Ask the association before removing a significant tree, and get the answer in writing. We can supply the written assessment that boards usually want.

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 Oak Hills

Do I need approval to remove a tree in Oak Hills?

From the county, usually not, because Oak Hills is unincorporated. From the homeowners association, quite possibly. Common-area trees are entirely theirs, and the covenants can apply to trees on private lots. Ask before you book the work.

Does the historic district listing protect my trees?

Not directly. National Register listing is an honor and brings no tree permit with it. The rules that matter come from the association's covenants and design guidelines, which were written to protect the character that earned the listing.

A tree in the greenway hangs over my roof. Who prunes it?

The association, because it is their tree. Report it in writing with photos. They can hire the work or give you permission to have it done. Without that permission, leave it alone.

How should I care for a native oak in my yard?

Mostly by leaving the ground under it alone. Keep irrigation, new soil, paving and trenching away from the root zone, and limit pruning to dead and hazardous limbs. Oregon white oaks decline from kindness more often than from neglect.

Do you give free estimates in Oak Hills?

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.
