Mrs. Katherine Cole
1804 Selva Grande Dr.
Jacksonville, FL
Dear Mrs. Katherine Cole,
Please find below my Tree Risk Assessment report for your hickory tree and water oak tree.
REPORT
SUMMARY
I assessed the risk of 2 trees on your property using a Level 1 and Level 2 assessment. I found
evidence of dieback in the crown and bacterial wet wood at the base which increases the
likelihood of failure. Multiple assets including people and your property could be struck if these
trees failed causing significant damage. This resulted in a risk rating of HIGH. With removal,
the risk rating will be eliminated. I am recommending removal of the trees due to the risk of
damage in normal weather.
ASSIGNMENT
My assignment was to provide a tree risk assessment for one hickory tree (Carya
floridana) and one water oak tree (Quercus nigra). The trees are located on property
described as: 1804 Selva Grande Dr. Jacksonville, FL. I conducted my inspection on
the afternoon of January 29th, 2025.
This report contains proprietary information and is
for the exclusive use of Mrs. Katherine Cole. This
report can be shared with the city of Jacksonville to
comply with tree protection regulations.
METHODOLOGY
I performed a Level 1 and Level 2 Tree Risk
Assessment based on the ANSI A-300 (Part 9, 2017)
Tree Risk Assessment standard and used the
methodology defined in the International Society of
Arboriculture’s Best Management Practice for Tree
Risk Assessment (2017). I considered your property
as likely to be impacted if the trees are not removed.

OBSERVATIONS
The Tree. Tree #1 is 9-inch DBH (Carya floridana). Tree #2 is 25-inch DBH
(Quercus nigra). These are prominent trees in the area, meaning that they are exposed
to the wind.
Tree Health. The trees are in poor health based on a scale of poor, fair, good, and
excellent.
Defects and conditions of concern. A visual examination of the trees revealed There
is breakage in the crowns, rot & bacterial wet wood present which increases the
likelihood of failure. Even with mitigation efforts, the residual risk of damage would
be too high, therefore, removal of both trees is recommended.
ANALYSIS
The Primary Concern
The primary concern for these trees is the likelihood of failure in normal weather.
Given the size of the trees and risk of damage, these trees are categorized as HIGH
RISK. If the trees were to fail, the property and multiple targets could be in danger.
Risk Tolerance
Risk tolerance is the amount of risk you are willing to accept. Different people have
varying amounts of risk they will tolerate. You will have to decide your own risk
tolerance and decide on a course of action for this tree. Be aware that all trees begin
at a low risk rating.
ASSUMPTIONS AND LIMITING CONDITIONS
My inspection was a ground based visual inspection. The inspection was limited to
defects that can be seen while standing on the ground. There may be defects below
ground or in the canopy that were not visible from this perspective. These hidden
defects may result in the failure of branches, trunks, or roots. No other trees on this
property were inspected other than those specifically addressed in this report.
