Arboricultural Consulting Services in Seattle & the Greater Puget Sound

Yes — many cities require an arborist report before approving tree removal permits, especially for protected trees, development projects, environmentally critical areas (ECAs), or hazardous tree claims. Arborist reports are commonly requested by cities such as Seattle, Bellevue, Tacoma, Redmond, and other Puget Sound municipalities to document tree species, size, condition, risk factors, site impacts, and proposed mitigation measures.

A professional arborist report may include:

• Tree inventory and measurements
• Tree risk assessment (TRAQ)
• Health and structural condition evaluation
• Construction or development impacts
• Tree preservation recommendations
• Replanting or mitigation plans
• Permit support documentation

Requirements vary by city and project type. In many cases, an ISA Certified Arborist report can help property owners avoid permit delays, code issues, or incomplete applications.

Yes. Our ISA Certified Arborists provide tree protection planning, root-zone assessments, preservation recommendations, and construction-related consulting. We help property owners, builders, and contractors identify potential impacts from excavation, grading, access routes, and soil compaction, and develop practical measures to protect retained trees.

Yes. We regularly assist homeowners, builders, architects, developers, and property managers with arborist documentation required for construction permits, redevelopment projects, and municipal tree code compliance throughout Seattle, Bellevue, Tacoma, and the greater Puget Sound region.

Our arboricultural consulting services may include:

• Tree Protection Plans (TPPs)
• Root impact and critical root zone evaluations
• Arborist reports for permitting and development review
• Tree preservation and mitigation recommendations
• Construction monitoring and site inspections
• Hazard tree evaluations and retention feasibility assessments
• ECA, shoreline, steep slope, and protected tree documentation

We work with project teams to help reduce tree impacts, improve permit readiness, and provide practical recommendations that align with municipal tree regulations and site development goals.

Arborist report costs vary widely depending on the number of trees involved, project complexity, site conditions, permitting requirements, travel time, and the level of documentation required. Simple arborist reports for a single tree or basic permit review may start in the few-hundred-dollar range, while larger development, preservation, or multi-tree assessments can cost substantially more.

Factors that commonly affect arborist report pricing include:

• Number of trees being inventoried or assessed
• TRAQ risk assessment requirements
• Construction or development impacts
• Tree protection planning and mitigation requirements
• Municipal permitting and code complexity
• Site access limitations or steep slopes
• Advanced inspections, climbing assessments, or aerial evaluations
• Report turnaround time and rush scheduling

Some reports only require a brief site visit and basic documentation, while others involve extensive field measurements, mapping, photography, root zone analysis, preservation planning, or coordination with builders, architects, engineers, attorneys, or municipalities.

We provide clear scopes of work and pricing recommendations before beginning arborist consulting services so property owners understand what level of assessment and documentation is appropriate for their project.

Yes. Arboricultural consulting can help identify trees suitable for preservation, evaluate potential construction impacts, and establish appropriate tree protection measures. Depending on project requirements, services may include tree inventories, root protection recommendations, preservation plans, and construction monitoring.
