From Tree Risk Assessments to Permit-Ready Reports: Why Puget Sound Homeowners & Builders Rely on Certified Arborists

  • What is an ISA Certified Arborist and why should I hire one?

    An ISA Certified Arborist has proven expertise in tree biology, risk assessment, and best management practices. Hiring one ensures your arborist reports, risk assessments, and tree protection plans meet industry standards and are accepted by cities and insurers.

  • Do I need an arborist report to remove or prune a tree?

    Many Puget Sound cities, including Seattle, Bellevue, Renton, and Issaquah, require an arborist report for tree removal or major pruning, especially if the tree is significant or protected. Our reports meet city code and permitting requirements.

  • What is a Tree Risk Assessment (TRAQ)?

    A Tree Risk Assessment is a formal evaluation of a tree’s health and structural stability using the ISA TRAQ (Tree Risk Assessment Qualification) method. It provides a clear risk rating and recommendations for preservation, pruning, or removal.

  • What is a Tree Protection Zone (TPZ)?

    A Tree Protection Zone is an area around a tree that must stay undisturbed during construction to protect its roots and stability. Cities often require a TPZ plan as part of permitting. Our arborists design and monitor TPZs to meet code and keep projects on track.

  • How long does it take to get an arborist report?
