Tree removal permits in Oregon City

Oregon City’s tree rules live in OCMC 17.41, the tree protection, preservation, removal and replanting chapter, and they bite in specific places. A yard tree is generally yours to remove, but if the lot is under development review, or the tree stands in a water-quality, geologic-hazard or habitat overlay, Planning reviews it first. Heritage trees on the historic site inventory are regulated through the Historic Overlay.

If you are unsure which side of those lines you are on, check the overlay maps or call Planning before a crew is booked; the city’s Trees in Oregon City page is the starting point. Street trees are simpler: the Street Tree Removal and Replacement Permit is free, the replacement comes from the city’s Street Tree List (planting strips 3 feet or narrower are exempt), and right-of-way work must be done by a certified arborist. Code Enforcement and Public Works share oversight of right-of-way trees. The Oregon permit guide compares nearby cities.

Storm records for Clackamas County (covers Oregon City)

Clackamas County’s storm count is falling fast. NOAA’s record holds 198 reports, ranking the county 8th of Oregon’s 36, but the latest three years produced 48 against 86 in the three before, a drop of nearly half. Heavy snow leads with 64 reports, and wildfire is unusually high at 35, ahead of strong wind at 32 and winter storms at 28.

Fewer reports does not mean less exposure. FEMA’s National Risk Index (December 2025) rates strong wind Relatively High at 93.4 and ice storm Relatively High at 90.9, with overall risk Relatively High. Two-thirds of reports, 66 percent, land between November and February, with December, February and January the peaks, and late summer brings the fire share.

Power lines and utilities in Oregon City

No utility is mapped for Oregon City in our directory yet. Your power bill names the provider; look it up in the utility directory or call the number on the bill to learn who trims near the lines and where your responsibility for the service drop begins. With Clackamas County’s strong-wind rating at Relatively High, a limb over the drop is worth asking about before winter, and tree removal near power lines explains why a homeowner crew should stay clear of it.

Pests and quarantines

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

Emerald ash borer is confirmed in the area and Oregon City is inside the quarantine. Keep raw ash wood within the quarantine; it may leave only as chips 1 inch or smaller or as kiln-dried, debarked lumber, or after heat treatment to 160°F at the core for 60 minutes with ODA permission, and loads should be covered during the April 1 to September 30 flight period. Mediterranean oak borer is also confirmed: do not move cut oak firewood more than 10 miles, and chip or burn infested oaks, stump included, on site. Report either to the Oregon Invasives Hotline; details are on the EAB in Oregon page.

• 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

Growing conditions in Oregon City

Oregon City is in USDA hardiness zone 9a, mild enough for a wide range of replacement trees. If you are planting a street tree, the choice is limited to the Street Tree List. In the yard, the county’s 35 wildfire reports argue for a defensible-space layout near the house, and with ash under quarantine, a non-ash species avoids repeating the problem.

Labor index for Oregon City

BLS’s Portland-Vancouver-Hillsboro estimate covers Oregon City: a $35.04 mean and $36.33 median hourly wage for tree trimmers and pruners, from about 1,160 workers in the metro. That figure is a wage rather than a job price; quarantine handling of ash wood and certified-arborist requirements for street trees both add crew time that the modeled ranges on the service pages reflect.

What to do next

Check the overlay maps first; if the tree is outside them and the lot is not in development review, no city permit is needed. For a street tree, file the free permit and plan the replacement. If the tree is an ash, line up disposal that respects the quarantine. Debris burning follows Oregon DEQ rules, covered in the yard debris burning guide. Confirm a company in the Oregon license lookup before signing.
