CanopyMetrics provides arboricultural consulting grounded in published standards, honest assessment, and a single principle: we work for the facts, not the outcome.
CanopyMetrics is an independent arboricultural consulting firm based in the North Bay, California. We serve property owners, developers, attorneys, and municipalities across Marin, Sonoma, and Napa counties — and we travel for litigation support work when the assignment requires it.
Independence is the foundation of everything we do. CanopyMetrics does not sell tree-removal services, pruning contracts, or any other tree care work. We have no financial interest in any outcome — our only obligation is to deliver an accurate, defensible assessment based on the evidence and applicable standards.
That independence matters most when the stakes are high: a development project requiring permit approval, a property dispute turning on whether a neighbor's oak poses genuine risk, or a personal-injury case where tree failure is at issue. In those contexts, a consultant tied to a service company has a conflict of interest that undermines the assessment. We don't have that problem.
The International Society of Arboriculture (ISA) Utility Specialist credential recognizes advanced knowledge in arboriculture as it applies to utility-line clearance, high-voltage environments, and the intersection of tree management with infrastructure. This is a distinct, specialty-level certification beyond the base ISA Certified Arborist credential.
The TRAQ qualification certifies competency in performing structured tree risk assessments using the ISA's standardized methodology. All risk assessments conducted by CanopyMetrics follow the ISA TRAQ two-step process and use the published ISA Best Management Practices for Tree Risk Assessment.
The American Society of Consulting Arborists Registered Consulting Arborist designation is the industry's highest credential for consulting practice. Candidacy requires documented consulting experience, a written examination, peer review, and adherence to ASCA's code of ethics. This credential is currently in progress and has not yet been conferred.
Every tree risk assessment follows the ISA Tree Risk Assessment Qualification (TRAQ) methodology — the published, peer-reviewed standard for structured risk evaluation. This is not a proprietary process; it is the same framework adopted by ISA chapters, municipalities, and courts across North America.
The assessment begins with a documented site visit. We record tree species, size (DBH and height), structural defects, signs of disease or decay, site conditions, and proximity to targets — people, structures, and utilities. Where warranted, advanced diagnostic tools (resistograph, sonic tomography, aerial inspection) are documented and noted in the report.
Using the ISA TRAQ two-step process, we assign likelihood of failure ratings and likelihood of impact ratings for each identified failure part and target. The resulting risk rating — Low, Moderate, High, or Extreme — is determined by the intersection of failure probability and consequence, not by subjective impression.
The assessment is delivered as a written report containing: site and tree inventory data, photographic documentation, the completed ISA risk assessment form, risk ratings for each assessed tree, applicable ordinance considerations, and recommendations for risk mitigation. Reports are written to withstand regulatory and legal scrutiny — they cite standards, not just conclusions.
CanopyMetrics does not perform, contract, or refer tree work. We do not benefit financially from any recommended action. This means every recommendation — whether it is to remove, retain, prune, or monitor — reflects only what the evidence supports. No revenue pressure, no referral arrangement, no conflict of interest.
For litigation support, expert witness retention, and complex construction-impact cases, we travel outside the North Bay as the assignment requires. Contact us to discuss your jurisdiction.
The American National Standards Institute A300 series is the authoritative standard for tree care operations in the United States. ANSI A300 governs pruning, risk assessment, integrated pest management, and supplemental support systems. All work recommendations reference A300 where applicable.
The ISA publishes Best Management Practices (BMPs) series that operationalize ANSI A300 standards for practitioners. CanopyMetrics references the relevant BMP guides — including Tree Risk Assessment, Pruning, and Utility Pruning — in all deliverables.
Every assessment considers the tree ordinances of the relevant jurisdiction — permit requirements, protected species, mitigation ratios, and heritage tree designations. We maintain a working knowledge of North Bay tree ordinances across all 10 major jurisdictions. See our ordinance reference guide for compiled details.
Risk assessments follow the ISA Tree Risk Assessment Qualification (TRAQ) structured methodology. This includes use of the published ISA risk assessment matrix and documentation forms, ensuring consistency and defensibility across all assessments.
Describe your project — whether it's a single-tree risk assessment, a development application requiring an arborist report, or a litigation matter — and we'll respond within one business day.
