Tree Risk Assessments

What This Service Involves

For high-value or high-target public trees, our TRAQ-qualified arborists perform structured risk assessments that go beyond a visual pass. Each assessment weighs the likelihood of failure, the likelihood of impacting a target, and the consequences, producing a documented risk rating and mitigation options. We evaluate site history, load exposure, and defect severity, and can incorporate advanced tools such as decay detection where warranted. Reports are written to withstand scrutiny in claims or litigation and to give decision-makers clear, ranked choices. This level of rigor is ideal for signature trees, heritage specimens, and locations with heavy public occupancy.

Benefits

Quantifies risk using a recognized TRAQ methodology; Produces litigation-ready, defensible documentation; Ranks mitigation options against cost and residual risk; Focuses spending on trees with the highest exposure

Our Process

1) Target and site-history review for the subject trees; 2) Structured evaluation of failure likelihood and consequence; 3) Optional advanced decay or load diagnostics; 4) Written risk report with rated mitigation recommendations

What Affects the Cost

Number and complexity of trees assessed; Level of advanced diagnostic testing used; Target occupancy and site-exposure analysis; Reporting depth and defensibility required; Reassessment interval for monitored trees

Best Time of Year

Assessments are performed year-round; scheduling ahead of the fall storm season and after significant weather events provides the most timely risk picture.
