What Is an Arborist Report?
An arborist report is a detailed professional document outlining a tree’s condition, structure, and management recommendations. Prepared by a Certified Arborist, these reports help clients meet legal, construction, and municipal requirements while protecting trees and property. Evergreen’s reports meet ISA, TRAQ, and local government standards.
When You Need a Professional Arborist Report
Many East Bay cities and organizations require certified documentation for tree work, construction, or insurance purposes. Evergreen prepares official reports for a wide range of needs.
Development & Construction Projects
Local ordinances often require arborist reports before, during, and after construction to document protected trees and potential impacts. We evaluate site plans, assess root zones, and provide protection recommendations to ensure compliance with city and county regulations.
Tree Removal or Pruning Permits
Cities and HOAs frequently require an arborist report to approve tree removals or large pruning projects. Our certified documentation outlines the tree’s condition, safety considerations, and justification for removal or preservation.
Insurance & Legal Documentation
Evergreen provides detailed, unbiased reports for insurance claims, property damage disputes, and legal proceedings involving tree failure or liability. Our reports stand up to professional and legal review.
Municipal & HOA Requirements
Many East Bay municipalities, HOAs, and public agencies require periodic arborist reports for compliance and long-term management. Evergreen delivers standardized documentation that satisfies all local requirements.
- What’s Included in an Arborist Report
Every report prepared by Evergreen Tree Care follows ISA and municipal standards, providing clear, complete, and defensible documentation.
Tree Identification & Condition Assessment
We identify and document each tree by species, size, and condition. Using visual and diagnostic methods, we evaluate health, structure, and site factors that affect safety and preservation potential.
Site Evaluation & Impact Analysis
Our arborists assess site conditions, grading, and construction plans to determine potential impacts to trees. We include recommendations for root zone protection and preservation during development.
Risk Rating & Recommendations
Each report includes a professional assessment of tree risk, along with actionable recommendations for pruning, mitigation, or removal when needed.
Compliance Summary & Documentation
We summarize all findings in a clear, organized report formatted to meet local or agency-specific requirements. Supporting photos, maps, and reference tables are included where applicable.
