Grove Tree Care | ISA-Certified Arborists | Serving Lake Oswego and Surrounding Clackamas County Communities
Professional Tree Care in One of Oregon’s Most Tree-Protected Cities
Professional Tree Care in One of Oregon’s Most Tree-Protected Cities
Lake Oswego has one of the most robust urban tree canopies in Oregon — <parameter name=”file_text”>roughly 44% citywide canopy cover — and one of the most detailed tree codes in the Portland metro to protect it. The city has held Tree City USA designation for over three decades, and its residents take their trees seriously. So do we.
Grove Tree Care’s lead arborist, Kevin Fox, has over 40 years of experience providing expert tree service throughout Lake Oswego. Kevin and our ISA Certified Arborist team know the neighborhoods, the species, and — critically — the permit process. Lake Oswego’s tree removal regulations are among the most involved in the region, and navigating them correctly is just as important as the quality of the work itself. We handle both.

Tree Services We Provide in Lake Oswego
Tree Removal
Lake Oswego’s mature landscape means many removal jobs involve large, well-established trees in tight residential settings — near lake-view homes, on sloped lots in Uplands and Palisades, or in the densely wooded properties of Forest Highlands and Glenmorrie. Our crews are experienced with advanced rigging, precision lowering, and complex removals that protect the surrounding landscape. We also handle the full permit process, which in Lake Oswego is required for nearly every removal.
Tree Trimming and Pruning
From the towering Douglas firs of Lake Grove to the ornamental maples lining streets in First Addition and Bryant, Lake Oswego’s tree canopy is diverse and mature. Regular, expert pruning keeps your trees structurally sound, aesthetically beautiful, and less vulnerable to storm damage. We follow ISA best practices on every job — no topping, no flush cuts, no shortcuts.
Emergency Tree Services
Lake Oswego’s 2024 winter storm left hundreds of homeowners dealing with damaged and fallen trees — and Lake Oswego’s tree code applies even in emergencies. Grove Tree Care responds quickly to storm damage throughout Lake Oswego, and we know how to handle the city’s emergency permit documentation so your property is protected without cutting corners on compliance.
Call 503-208-4071 any time you’re dealing with a tree emergency.
Stump Grinding and Removal
After a permitted removal, the stump doesn’t have to remain. We grind stumps to below grade throughout Lake Oswego, restoring your yard for replanting or lawn use. Stump grinding is available as part of a removal job or as a standalone service.
Tree Health Assessments and Arborist Reports
Lake Oswego’s permit process for hazard and dead trees requires documentation from a certified arborist. Grove Tree Care’s ISA Certified Arborists provide written assessments that satisfy city requirements, document tree condition thoroughly, and give you a clear picture of what your tree needs — whether that’s treatment, cabling, or removal.
Tree Cabling and Bracing
Lake Oswego’s large, mature trees are often worth saving — but may need structural support to remain safe. Cabling and bracing stabilizes weak branch unions and reduces the risk of failure during wind events. It’s a cost-effective alternative to removal when the tree is otherwise healthy and has significant value to your property.
Lake Oswego Tree Removal Permit Rules — What You Need to Know
Lake Oswego has one of the most detailed private tree codes in the Portland metro. <parameter name=”file_text”>Any tree 6 inches DBH (diameter at breast height, measured 4.5 feet from the ground) or greater requires a permit before removal. This applies to virtually every mature tree on a residential property in the city.
Here’s how to measure DBH: wrap a tape measure around the trunk at 4.5 feet above the ground and divide the circumference by 3.14. If that number is 6 or greater, a permit is required.
The Six Permit Types
Type I — For trees between 5 and 10 inches DBH on single-family residential lots. Limited to two trees per calendar year. Issued over the counter, no fee, straightforward process.
Type II — For trees that don’t qualify for a Type I. Requires a site plan, a Type II questionnaire, a mitigation plan, and a 14-day public comment period. Fee: $50. Takes approximately one month to complete. One-to-one mitigation (replacement tree planting) is required for all Type II removals.
Dead Tree Permit — For trees that are confirmed dead. Requires documentation including a photo and a site plan. A fee applies.
Hazard Tree Permit — For trees that are cracked, split, leaning, or damaged to the degree that failure is likely. Requires a Hazard Evaluation Form completed by an ISA Certified Arborist. This is where our arborist reports become essential.
Emergency Permit — For immediate hazards. Must be documented promptly after emergency work is completed.
Invasive Tree Removal Permit — Free permit for removing invasive species like English holly, black locust, and similar trees.
Important Additional Rules
- Mitigation is required for all Type II removals. If there’s insufficient space on your property to plant a replacement tree, mitigation may be placed elsewhere in Lake Oswego or a fee paid to the city.
- Topping is regulated — removing 50% or more of a tree’s crown without a permit is treated as an unpermitted removal and can result in enforcement action.
- Significant trees (over 15 inches DBH, healthy, and non-invasive) trigger additional review under Type II permits.
- Street trees always require a separate public tree permit. Contact Lake Oswego Planning at 503-635-0290 or email trees@lakeoswego.city.
Grove Tree Care manages the permit process for our Lake Oswego customers. We prepare the documentation, file the application, coordinate the public notice period for Type II permits, and track the timeline — so you don’t have to.
