Identify Hazards Before They Become Emergencies

Mature trees are an asset to your property — but when they’re not structurally sound, they can pose a serious risk to people, buildings, and infrastructure. At Arborists of America, Inc., we provide expert Tree Risk Assessments throughout Portland and beyond, helping homeowners, HOAs, and property managers understand and manage tree-related hazards before they lead to costly damage.

What is a Tree Risk Assessment?

A Tree Risk Assessment is a detailed inspection performed by a certified arborist to evaluate a tree’s structural integrity, likelihood of failure, and potential consequences if failure occurs. Our assessments follow ISA Tree Risk Assessment Qualification (TRAQ) standards and include:

• A visual inspection of roots, trunk, and canopy

• Identification of structural defects, decay, cracks, or leaning

• Evaluation of target zones (buildings, roads, power lines)

• Risk rating using industry-standard methods

• Recommendations for pruning, cabling, bracing, or removal

• Documentation for insurance, permitting, or legal protection

Who Needs a Tree Risk Assessment?

• Homeowners with large or aging trees near structures

• HOAs managing shared greenspaces or community lots

• Commercial properties with customer traffic or liability concerns

• Cities, schools, and agencies responsible for public trees

• Anyone applying for a tree removal permit in Portland

Portland-Specific Tree Risk Factors

With Portland’s combination of heavy rains, windstorms, and clay-heavy soil, trees are especially vulnerable to root rot, windthrow, and sudden failure. Common high-risk species in the area include:

• Bigleaf Maples with co-dominant stems

• Black Cottonwoods with decay-prone trunks

• Topped or previously damaged Douglas Firs

• Leaning or cracked trees in older urban neighborhoods

Our arborists are trained to assess these risks and provide credible, actionable solutions — not guesswork.
