Why Tree Risk Assessment Matters
Even healthy-looking trees can pose safety risks. Factors like decay, root damage, or structural imbalance can lead to failure during storms or heavy winds. A professional tree risk assessment helps you identify problems early, reduce liability, and plan proactive maintenance that keeps people and property safe.
Our Professional Tree Risk Assessment Process
Evergreen’s TRAQ Certified Arborists follow a systematic process to evaluate each tree’s condition and risk level. Our reports are designed to meet ISA and municipal standards, giving you clear, defensible data to guide maintenance and removal decisions.
Site & Tree Condition Evaluation
We begin with a visual inspection and environmental review, noting factors such as soil stability, canopy density, and site usage. This establishes the context for identifying potential hazards.
Structural & Environmental Factors
Arborists examine trunk, branch, and root structure for decay, cracks, and weaknesses caused by pests, disease, or past pruning. We also assess environmental conditions like wind exposure and irrigation patterns that affect stability.
Data Collection & Documentation
Each tree is documented using standardized ISA risk rating criteria. We record species, size, condition, and recommended actions—supported by photos or GIS data when required.
Reporting & Risk Mitigation Recommendations
Final reports summarize findings in clear, actionable language. We prioritize trees for maintenance, monitoring, or removal, helping you plan budgets and protect site users with confidence.
TRAQ Certified Arborists
Evergreen’s TRAQ Certified (Tree Risk Assessment Qualification) Arborists bring formal training and field experience to every inspection. Our assessments meet the highest industry standards for accuracy and documentation—trusted by cities, HOAs, insurance providers, and property managers alike.
