Common Tree Removal Scenarios
A dead tree is one that has stopped producing leaves and lost the structure that kept it standing, and in Portland, decaying wood becomes a liability in the city’s periodic windstorms. As the trunk and roots rot, the tree can fail with little warning.
Dead trees attract pests and spread wood-decay fungi to nearby healthy trees, dragging down both safety and curb appeal.
Note that Portland requires a removal permit for trees 12 inches in diameter or larger and mandates replanting. Monkeyman’s office team handles the Urban Forestry process so a dead tree is removed correctly and in compliance.
An overgrown tree is a healthy tree that has outgrown its space, pushing into rooflines, utilities, or a neighbor’s property. Portland’s tree-friendly climate pushes trees past their boundaries quickly.
When a tree threatens a structure or crosses a property line, the owner is responsible for safe removal, and roots can disturb foundations and sidewalks before the canopy looks like a problem.
Because the city protects its canopy, removing an overgrown tree 12″ DBH or larger requires a permit and replanting, Monkeyman’s manages both, and recommends pruning where it solves the issue.
A diseased tree carries an infection that weakens it from the inside, and it can look healthy while it’s hollow underneath. In Portland’s wet environment, root rot, heart rot, and Verticillium wilt are all common.
Heart rot in particular often goes unnoticed until a tree is already a removal candidate, and infections can spread to surrounding vegetation.
Monkeyman’s ISA Certified Arborists diagnose the disease, navigate the city’s permit and replanting requirements, and remove trees that can’t be saved, treating first whenever it’s viable.
A storm-damaged tree has been cracked, split, uprooted, or partly destroyed by wind, ice, or debris. Portland’s ice storms leave cracked, split, and leaning trees citywide.
As a guideline, more than 50% crown loss usually means removal, though a vigorous tree that kept its leader can often recover.
Importantly, Portland can require a permit even for storm-downed tree removal, including retroactively, so it’s wise to use a service that handles the Urban Forestry process for you. Monkeyman’s does exactly that.
Emergency tree removal is the 24/7 response needed when a tree has fallen, or is about to, onto a home, vehicle, road, or power line. These removals are dangerous and call for a careful, experienced crew.
For high-risk jobs, Monkeyman’s brings in a crane through our Smith Crane partnership to control the hazard and prevent sudden movement mid-cut.
When a tree falls on a Portland property, we respond day or night and manage the city’s emergency-removal permitting so the cleanup is handled correctly.
View clearing is the selective removal or pruning of trees blocking a scenic sightline. Portland’s hills offer some of the best views in the region, from the West Hills to the bluffs above the Willamette.
Because the obstructing trees usually grow on a slope below the view, the work is technical, and permit-sensitive given the city’s 12″ DBH threshold.
Monkeyman’s plans include every cut to open your view while keeping you compliant with the city’s tree code and preserving the trees that anchor your landscape.
Lot clearing is the systematic removal of trees and vegetation to prepare a site for construction or grading. Portland’s infill development almost always starts with tree removal.
Larger jobs may use a track hoe or bulldozer, with trees removed in sections where they can’t be felled directly.
Because the city’s canopy rules and replanting requirements make compliance essential, Monkeyman’s clears residential and commercial lots and manages the permits and mitigation for you.

FAQ
Lake Oswego has one of the most protective tree codes in the metro, and permits are commonly required for removals well down to modest trunk diameters, meaningfully stricter than neighboring cities. Assume you need one, and let us verify and handle the application before any cutting.
Our yard is on Boones Ferry Road, so Lake Oswego is effectively our home turf. It means shorter travel for crews, faster turnaround on estimates and emergencies, and 30-plus years of knowledge of the local soils, slopes, and codes, including which lakefront and hillside properties need specialized access.
Yes. Lake Oswego properties frequently combine steep grade, retaining walls, limited access, and a shoreline you can’t drop debris onto. We rig from above, use compact equipment and ground protection on slopes, and plan debris routes before the first cut so nothing ends up in the lake.
All of them: First Addition, Forest Highlands, Lake Grove, Mountain Park, Palisades, Westlake, Iron Mountain, and the Uplands, plus the lakefront and canal properties. Many carry HOA or neighborhood association rules on top of city code, and we work within both.
Oversized Douglas fir and western red cedar on residential lots too small for them, root conflict with retaining walls and driveways on the hillsides, and drought-stressed cedars showing dieback. The recurring question here isn’t whether a tree is beautiful; it’s whether a 120-foot fir belongs 20 feet from a house on a slope.
