Tree service in Tualatin, Oregon

Tree removal permits in Tualatin

Tualatin counts trees, not inches. Under the Tualatin Development Code (Chapter 33, per the city’s page) you may remove up to 4 trees in a calendar year on an ordinary lot with no permit at all; the fifth tree in that year needs one from Community Development, Planning (503-691-3026). The count rule drops away on property covered by a site-plan approval, where larger removals go to Architectural Review, and it never covers Heritage Trees. Nothing on the city page states a size threshold, so confirm with Planning how it defines a tree before you assume a sapling counts as one of your four.

If your removal is one to four trees on a plain residential lot, write down the date and the tree count and keep it with your records, since the allowance resets by calendar year. Wetlands and other sensitive areas add a second sign-off from Clean Water Services, and street trees along public streets belong to Tualatin Parks and Recreation, whose removal page was unreachable at the last check, so phone before touching anything in the planting strip. The fee amount was not posted; ask for it when you call. Statewide context is in the Oregon permit guide.

Storm records for Washington County (covers Tualatin)

Tualatin’s most recent large storm episode is also its most instructive. On 2025-02-13 a warm front rode up over cold air parked in the valley and delivered snow, sleet and freezing rain across western Oregon for two days; NOAA tied four reports to it and named the Tualatin Valley forecast zone. Cold-air overrunning, rather than a single wind event, is the setup that puts ice on leafless limbs here.

Across the full record NOAA logged 104 reports for Washington County since 2016, ranking it 23 of 36 Oregon counties: high wind leads with 30, then heavy snow 24, strong wind 21, winter storm 12 and ice storm 4. January, February and December are the peak months, and 69% of reports fall between November and February. The recent three years brought 25 reports against 29 in the three before, so the pace is steady rather than rising. FEMA’s December 2025 National Risk Index rates ice storms in the county Relatively High (score 91.4) and strong wind Relatively Moderate (80.1).

Power lines and utilities in Tualatin

Portland General Electric is the utility for Tualatin. PGE trims around its transmission lines and its primary and secondary distribution lines, and it asks customers to keep at least 10 feet of clearance around primary lines; the exact distance varies with voltage under Oregon PUC rule OAR 860-024-0016. The service wire to your house is trimmed only when branches strain or rub it, so routine clearance there is yours, and PGE asks that nothing be planted under or around its wires. Outages go to 503-464-7777 or 800-544-1795, answered 24 hours.

If a different provider bills your Tualatin address, the utility directory lists each one’s trimming program. The rule that does not change with the provider: a limb lying on a wire is a call to the utility rather than to a tree company, as the power-line page explains.

Pests and quarantines

Emerald ash borer (EAB) · quarantineMediterranean oak borer (MOB)

Two borers change how wood leaves a Tualatin job. Emerald ash borer is confirmed in Washington County and the county is inside Oregon’s quarantine, so raw ash wood stays put: it leaves only as chips of 1 in or smaller, as kiln-dried debarked lumber, or after heating the core to 160 F for 60 minutes with ODA permission, and loads are covered during the April 1 to September 30 flight period. Mediterranean oak borer is confirmed too, without a quarantine; the guidance is not to move cut oak firewood more than 10 miles and to chip or burn infested trees, stump included, on site, with any burning subject to Oregon DEQ rules.

Report either insect with photos and a location to the Oregon Invasive Species Online Hotline. The EAB in Oregon page covers what a dying ash looks like and why removal gets harder the longer you wait.

• Emerald ash borer (EAB): OR (ODF/ODA): keep raw ash wood inside the quarantine; move only as <=1-in chips or kiln-dried debarked lumber, or heat 160F core for 60 min with ODA permission; cover loads during flight period Apr 1
• Mediterranean oak borer (MOB): Don't move cut oak firewood >10 miles from source; cut then burn or chip (<=1 in) infested trees including the stump on site; report with photos/location to Oregon Invasives Hotline

Growing conditions in Tualatin

Tualatin sits in USDA zone 9a on the 2023 map. That mild rating is why broadleaf evergreens and marginal ornamentals survive in yards here, but mild winters are not light ones: the February 2025 episode shows the valley still gets freezing rain, and ash and oak, two of the valley’s common yard trees, are the ones with borers on them. Replant with the pests in mind, favoring species other than ash, and plant in the wet dormant months so roots are established before the dry summer.

Labor index for Tualatin

BLS puts the mean wage for tree trimmers and pruners across the Portland-Vancouver-Hillsboro area at $35.04 an hour (May 2025); the median is $36.33 and the survey counts 1,160 people in the trade. A wage is not a price: the crew-hour a company bills on top of it covers the bucket truck, chipper, dump fees and insurance. Use the modeled ranges in the cost guide as a sanity check on bids, not as a quote.

ZIP codes and nearby cities

Tualatin’s land falls mostly in ZIP codes 97062, 97224, 97035 and 97140, and the Census estimates 28,139 people in 2025, barely changed from 27,942 in 2020. Tigard and Sherwood are each 3 miles away, Lake Oswego 4, Wilsonville 5, and West Linn and Beaverton 7; the permit rules on those pages differ from Tualatin’s count-based allowance, so a company that works several of them has to track which code applies at each address. The Washington County page holds the county-wide hazard ratings and burn rules.

Tree services in Tualatin

Tualatin’s four-tree allowance decides which service needs paperwork: tree removal is the one that counts against it, and the page to read first if you have more than four trees to take out. Trimming is not part of the removal count, though street trees in the planting strip belong to Parks and Recreation. Stump grinding inside the EAB quarantine means ash grindings stay on site or leave as chips under 1 in, and emergency service is the page for the ice-and-snow failures of February 2025.

What to do next

Count before you cut. One to four trees in the calendar year on an ordinary lot means no permit; a fifth, a Heritage Tree, a site-plan-approved property or a wetland buffer means a call to Planning at 503-691-3026 and possibly to Clean Water Services. Then have the tree looked at: a risk assessment tells you whether it needs to come out at all, and ash trees in particular deserve a check for borer damage.

Verify any company you hire through the Oregon license lookup, ask where the ash wood is going, and compare two or three written bids against the modeled range before you sign.
