Enhance Your Trees’ Lifespan with Expert Care
At Davis Family Arbor Services, we provide professional tree risk assessments in accordance with ISA and ANSI A300 standards. Understanding the level of assessment your tree requires helps us recommend the best approach to keep your property and loved ones safe.
Tree Risk Assessments
What Is a Tree Risk Assessment?
A tree risk assessment is a systematic process used to evaluate the likelihood of tree failure and its potential impact on people, property, or activities. It helps property owners make informed decisions about tree care based on their personal level of acceptable risk.
Our assessments are performed by an ISA Board Certified Master Arborist with Tree Risk Assessment Qualification (TRAQ).

Risk Rating Report
We provide a clear, easy-to-understand risk rating that outlines the potential hazards your tree poses to people or property.
Action Plan
Based on the level of risk, we offer expert recommendations such as cabling, pruning, or removal.
Choose Your Depth
Tree Risk Assessment Levels
Limited Visual Assessment
Starting at$250What It Is?
A quick assessment of one or more trees to identify obvious defects or hazards.
When It’s Used?
During a walkthrough or drive-by inspection to prioritize trees for further evaluation.
Process
Visual inspection from a single vantage point (no tools or climbing involved). Used for rapid assessments following storms or when surveying large properties.
Example
A visual scan to identify trees with broken limbs or uprooted roots after a windstorm.
Basic Assessment
Starting at$500What It Is?
A 360° visual inspection of the tree and its immediate site conditions
When It’s Used?
To evaluate specific concerns about a tree’s health or structural stability
Process
The arborist walks around the tree, examining the roots, trunk, and canopy. Basic tools may be used (e.g., mallet for sounding, binoculars). Includes identification of structural defects, decay, or pest issues. A Tree Risk Assessment Report is provided to document findings and recommendations
Example
Evaluating a tree near your home with a visible cavity in the trunk.
Advanced Assessment
Starting at$750What It Is?
A detailed analysis using specialized tools and techniques to confirm the presence and severity of defects.
When It’s Used?
When a Level 2 assessment identifies concerns requiring further investigation.
Process
Diagnostic tools such as a Resistograph, sonic tomography, or air excavation may be used to evaluate internal decay, root health, or structural integrity. May involve climbing the tree or using aerial lifts to inspect the upper canopy. Results in a comprehensive written report with photographs, test data, and management recommendations
Example
Testing a mature oak near a playground for internal decay using sonic tomography.
Which Level Do You Need?
The appropriate assessment level depends on the tree’s location, condition, and your personal level of acceptable risk. We’ll help you decide during your consultation.
How a Risk Rating Is Reached
Likelihood, Impact and Consequences
A risk rating is not a judgement call. Likelihood of failure is combined with likelihood of impact to give a likelihood rating, and that rating is then weighed against the consequences of failure. These are the ISA matrices we work from.


What You Receive
Our Tree Risk Assessment Reports Includes:
Detailed findings and photographs
Recommendations for mitigation or management
Risk ratings (Likelihood of Failure x Consequences)

Disclaimer: The final decision regarding mitigation rests with the tree owner and their personal risk tolerance.
Warning Signs
Worried Your Tree Might Be A Hazard?
A tree that looks fine today could fail tomorrow. These are key signs that a risk assessment is needed.
Cracks or Splits in the Tree
These structural defects can fail without warning, especially during storms.
Fungus or Decay at the Base
Rot at the root collar or trunk base is a serious risk factor for collapse.
Large Limbs Over Structures
Falling limbs can cause injury or property damage if not addressed.
Unstable Roots Or Leaning
Leaning trees may have damaged roots and need immediate evaluation.
