647 Selva Lakes Blvd Arborist Letter 6.10.25 5525 St Augustine Rd. (904) 731-9100 Jacksonville, FL 32207 BushorsTree@gmail.com Jonathan Torres 6/9/2025 647 Selva Lakes Blvd Atlantic Beach, FL 32233 Mr. Torres, Please find below my Tree Risk Assessment report for your Live oak. REPORT SUMMARY I assessed the risk of one Live oak on your property using a Level 2 assessment. This assessment was done after a large codominant leader failure. The decay that will occur at this wound can lead to tree failure under normal weather conditions within 3 years. Multiple assets including people, houses and vehicles could be struck if this tree failed causing significant or severe damage. This resulted in a risk rating of HIGH. In my professional opinion, the tree should be removed due to this risk and mitigation options not being able to get below a moderate rating. ASSIGNMENT My assignment was to provide a Tree Risk Assessment for one large Live oak tree because of a large codominant leader failure causing damage to a vehicle in the driveway. The tree is located on the property of 647 Selva Lakes Blvd Atlantic Beach, FL 32233 at the front of the property, between the street and the house, on the left side of the driveway. I conducted my inspection on June 9, 2025. This report contains proprietary information and is for the exclusive use of Mr. Torres. This report can be shared with the City of Atlantic Beach to comply with tree protection regulations. METHODOLOGY I performed a Level 2 Tree Risk Assessment based on the ANSI A-300 Tree Risk Assessment standard and used methodology defined in the International Society of Arboriculture’s Best Management Practices for Tree Risk Assessment. I consider the people near the tree, the vehicles in the driveways and yours and your neighbor ’s houses as likely to be impacted if the tree failed. I used a 3-year time frame for this assessment. OBSERVATIONS Subject tree - The tree is a large (31” d.b.h.) Live oak (Quercus virginiana) that is approximately 45 feet tall with an approximate 75-foot spread. The tree is located in the front of the house, on the left side of the driveway. Tree Health - This tree is a mature tree that is generally in good health based on a scale of poor, fair, good, and excellent. Defects and areas of concern - A visual examination of the tree reveals large over-extended branches with significant end weight. Many of these branches are large aspect-ratio limbs, meaning that are greater than one third the size of the main leader. These types of large branches have a weaker attachment to the main leader, coupled with the significant amount of end weight these branches have a higher likelihood of failure. These limbs could be mitigated to a lower risk with end weight reduction. The main area of concern for this tree is the large codominant failure which has left a large jagged wound on the main trunk. This size and shape of this wound will prevent the tree from being able to provide the necessary response growth to prevent further decay. The tree also has an unbalanced canopy with limbs now exposed to wind loads they were once protected from. ANALYSIS Primary Concern - The primary concern for this tree is the codominant failure leaving the large wound in the trunk and the unbalanced canopy (load) on this defect. Given the trees large size and off-centered canopy this tree is categorized as a HIGH RISK for the adjacent homes, vehicles and people who would frequent the target zone. Additional Concern - Additionally, the large aspect-ratio limbs with weakened branch unions pose a MODERATE RISK of failure due to the excessive end weight and being exposed to new wind loads. RISK RATINGS EXPLAINED What does HIGH RISK for the adjacent homes, vehicles and people mean? Risk ratings are composed of three parts. My assessment determined that within the 3 year time frame: 1. The likelihood of failure is probable. 2. The likelihood of hitting a target is high. 3. The consequences or damage of failure would be significant. RISK TOLERANCE Risk tolerance is the amount of risk you are willing to accept. Different people have different levels of risk they are willing to accept. You will have to decide your own risk tolerance and decide on a course of action for this tree. RISK MITIGATION OPTIONS There are a few options that can be considered for mitigation: 1. Use reduction and removal cuts to significantly reduce the canopy. This would require 30-50% of the end weight of the limbs to be removed to reduce the overall length and weight of the canopy. Some heading cuts may be required to achieve the recommended reduction of canopy. With this pruning, the residual risk rating would become MODERATE. 2. Complete tree removal will mitigate to a level of NO RISK. 3. Do nothing and continue to monitor the tree with regular inspections. REINSPECTION If this tree is not removed, it should be re-inspected every 6 months unless you have additional health or safety concerns that warrant more frequent attention. The tree inspection service should be performed by an ISA Tree Risk Qualified (TRAQ) arborist skilled in the science of tree risk assessment. I can perform this service if needed. ASSUMPTIONS AND LIMITING CONDITIONS My inspection was a ground based visual inspection and did not include any internal drilling to detect decay. The inspection is limited to what can be observed from 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 failure of branches, trunks, or roots. No other trees were inspected other than the one addressed in this report.
