This letter is in regards to the current status and condition of 2 small
Water oak (Quercus nigra) trees located at the Burnsed residence at
1833 Tierra Verde Atlantic Beach, Florida 32233. The trees are marked
and both located in the front yard (west side) of the property.
The tree on the left (facing house) is approx. 25'ft in height with a 14"
DBH (diameter at breast height) and is leaning towards the street. The
2nd Water oak on the right-side front yard is approx. 30'ft in height
with a 16" DBH and is leaning over the garage/driveway. Both sub-
dominate trees have significant lean angles. Additionally, and more
importantly, they both have hollowed out sections approx. 1 5'ft from
the ground. Both of these cavities have compromised the trees
structural integrity. Water oaks don't compartmentalize (seal) these
problems and as a result they have both retained water which has
caused clear visual decay.
Based on these factors the trees pose indisputable risk to the
homeowner's safety. The only way to alleviate or mitigate this risk is
to remove the trees.
If you have any further questions let me know.
Sincerely,
A -/tf, k��
