Tree trimming in Beaverton, Oregon

Pruning rules and permits in Beaverton

Beaverton Code 5.05.102 requires a permit to remove or destroy a tree in the public right-of-way, filed as a Street Tree Removal Application. Pruning severe enough to kill a street tree falls under that same rule, so heavy cuts on a right-of-way tree should go through the city first; replacement is at the City Engineer’s discretion.

On private lots, the Development Code protects Significant Individual, Historic, Grove and Landscape trees and “Community Trees” of 10 inches DBH or larger. Trimming that keeps a tree alive is not removal, but over-cutting a protected tree can turn into a Tree Plan 2 question. Portland General Electric, which serves Beaverton, trims its transmission and distribution lines and trims the service wire to the house only when branches strain or rub it.

Power lines and utilities in Beaverton

PGE keeps at least 10 feet around primary lines, a figure that varies by voltage under OAR 860-024-0016, and asks customers not to plant under or around its wires. Outages go to 503-464-7777 or 800-544-1795, staffed around the clock.

Pest rules reach trimming too. Washington County is inside Oregon’s emerald ash borer quarantine, so ash prunings stay in the quarantine unless chipped to 1 inch or less, and loads should be covered from April 1 to September 30. Mediterranean oak borer is also confirmed here; keep cut oak within 10 miles. Details are on the Oregon EAB page.

What trimming costs in Beaverton

In Beaverton the line between utility work and your work sets much of the price. Distribution lines are PGE’s to clear, but the service wire to your house is yours unless branches strain it, and a limb touching it calls for a qualified crew and lands higher in the modeled range below. Ash and oak pruning adds disposal steps described further down.

BLS puts the Portland-Vancouver-Hillsboro mean tree-trimmer wage at $35.04 an hour across 1,160 workers. That is a wage, not a quote; the table below converts it into job ranges.

Modeled estimate, not quotes (method): crew-hours × $225 per crew-hour, rounded to $50.

When to trim in Beaverton

Ice, not wind, is Washington County’s standout hazard: FEMA’s National Risk Index (December 2025) scores ice at 91.4, Relatively High, and NOAA puts 69 percent of storm reports between November and February. Thin heavy crowns before December, the wettest month at the Nature Park station with 6.25 inches.

Ash trimming fits outside the April-to-September borer flight period. For replanting, Beaverton sits in hardiness zone 9a, and a removed street tree may need a replacement set by the City Engineer.

What to do next

Sort the job first: right-of-way trees go through the Street Tree Removal Application before any cut that could kill them, and service-line limbs need a qualified crew. Chip ash on site or keep it in the quarantine. Check the contractor in the Oregon license lookup guide, then call the number on this page to compare Beaverton crews.
