1 Summary
The City of Burbank Landscape and Forestry Service staff requested West Coast Arborists (WCA) conduct an assessment of seventy-two (72) Aleppo pines (Pinus halepensis) throughout the city that were scheduled to be removed due to safety concerns based on infrastructure conflicts. The field visits were conducted on October 9 – 11, 2024. Two trees were removed prior to the field visit (330 Lutge Avenue and 1131 North Sparks Street).
Thirty-five (35) trees were recommended for removal within one-year (1 year), twelve (12) trees were recommended for removal within one to two years (1 – 2 years), three (3) trees were recommended for removal within two years (2 years), thirteen (13) trees were recommended for removal within two to three years (2 – 3 years), one (1) tree was recommended for removal within three years (3 years), three (3) trees were recommended for removal within three to four years (3 – 4 years), two (2) trees were recommended for removal within four years (4 years), and one (1) tree was recommended for removal within five years (5 years). Two (2) trees requested for inspection were removed prior to the field visit. The recommended removal times were based on the general health, structure, form and any observed defects at the time of the site visit.
Introduction
Background and History
As the controlling authority for the parkway trees in the City of Burbank, the Department of Parks and Recreation Landscape and Forestry Services (City) is tasked with management decisions for these trees for the benefit and safety of the residents based on available data, consultant arborist recommendations, and resident input. Following an internal evaluation of pine trees the City identified seventy-two (72) Aleppo pine (Pinus halepensis) of concern and requested West Coast Arborist conduct an assessment to prioritize the removal schedule for these trees.
There have been several whole tree failures of similar trees within the City, along with multiple large branch failures in some of the subject trees that led to the initial internal evaluation of the pines citywide. The City has requested this independent evaluation of the trees to gather the information necessary to make management decisions based on the risk to public safety presented by the subject trees.

5 Limits of the Assignment
Only the trees shown in Figure 1 were included in the assessment. All other trees in the area were excluded. The recommendations in this report are based on the site information provided.
Discrepancies in the provided information from actual conditions may alter the findings of the assessment.
This was a ground-based assessment of visible tree parts. Subsurface soil conditions and tree parts below ground were not disturbed or observed. No soil excavation, coring, or aerial inspections were conducted as part of this assessment. Internal, buried, or hidden signs or symptoms of decay or disease may not have been observed.
No testing of soil or plant tissue for fertility or nutrient deficiency was requested. No valuation appraisal was requested to be part of this report.
Only visible targets were evaluated as part of this assessment. Unknown or hidden targets were not included.
All observations and recommendations are based on site conditions at the time of the inspection.
Any changes to the site conditions or trees after the date of the inspection may invalidate the observations or recommendations included in this report.
The observations and recommendations are the professional opinion of the arborist conducting the inspection based on education, training, and experience in tree risk assessment. Trees are living organisms that may fail due to hidden defects, sudden changes in environmental conditions, mechanical damage, or with no discernable defect or cause. This report does not offer any warranty or guarantee, expressed or implied, regarding the safety, health, or conditions of the trees included.
The recommendations presented are intended to provide the City with tree management options.
The City, as the controlling authority, will make the final decisions as to which trees shall be retained and which recommended mitigation measures, if any, will be implemented.
The report is not intended to be legal advice and does not represent legal advice as such.
Purpose and Use of the Report
This report is intended to provide the City of Burbank, Department of Parks and Recreation, Landscape and Forestry Services with information regarding the priority for removal of the trees included in the assessment.

Thirty-five (35) trees were recommended for removal within one-year (1 year), twelve (12) trees were recommended for removal within one to two years (1 – 2 years), three (3) trees were recommended for removal within two years (2 years), thirteen (13) trees were recommended for removal within two to three years (2 – 3 years), one (1) tree was recommended for removal within three years (3 years), three (3) trees were recommended for removal within three to four years (3 – 4 years), two (2) trees were recommended for removal within four years (4 years), and one (1) tree was recommended for removal within five years (5 years). Two (2) trees requested for inspection were removed prior to the field visit (330 Lutge Avenue and 1131 N. Sparks Street). The recommended removal times were based on the general health, structure, form and any observed defects at the time of the site visit.
Trees with signs of root or trunk decay were given the highest priority for removal, followed by those with significant trunk leans or bends. Other observed defects included twisted trunk structure, twisted canopy structure, codominant scaffold and/or secondary branches, and limited rooting space.
Recommendation
All the subject trees are scheduled to be removed by the City due to safety concerns related to root damage to the surrounding infrastructure. The subject trees have outgrown the available space. Tables 3 – 10 below listed the trees that are recommended for removal within one (1) year; one to two (1 – 2) years, two (2) years, two to three (2 – 3) years, three (3) years, three to four (3 – 4) years, four (4) years, and five (5) years. Overextended branches should be pruned back to appropriate unions for any trees that are to be retained. All pruning cuts will be made according to ANSI A300 Tree Care Standards and ISA Best Management Practices: Pruning, Third Edition.

20 Glossary
Codominant – stems or branches of nearly the same size and diameter that originate from a union.
Consequences of failure – Personal injury, property damage, or disruption of activities due to the failure of a tree or tree part.
Drip line – Imaginary line defined by the branch spread of a single plant or group of plants.
DBH-Trunk Diameter at Breast Height, 4.5 feet above ground level.
Frequent-The target zone is occupied for a large portion of the day or week.
Girdling Roots – Root that encircles all or part of the trunk of a tree or other roots and constricts the vascular tissue and inhibits secondary growth and the movement of water and photosynthates.
Improbable – The tree or tree part is not likely to fail during normal weather conditions and may not fail in extreme weather conditions within the specified time frame.
Level 2 Basic Risk Assessment – A detailed visual inspection of a tree and surrounding site that may include the use of simple tools. It requires that a tree risk assessor inspect completely around the tree trunk looking at the visible aboveground roots, trunk, branches, and site.
Likelihood of Failure – The chance of a tree or tree part failure occurring within the specified time frame.
Likelihood of Impact – The chance of a tree failure impacting a target during the specified time frame.
Low (Risk)-Defined by its placement in the risk rating matrix; consequences are negligible, and likelihood of failure is unlikely, or consequences are minor, and likelihood is somewhat likely.
Low Tree Vigor-Overall tree health is poor to fair. There are dead twigs and branches, and growth is reduced compared to other trees of the same species in a stand. The tree may be affected by pests or disease.
Minor (Consequence)-Minor personal injury, low to moderate-value property damage, or small disruption of activities.
Moderate (Risk)-Defined by its placement in the risk rating matrix; consequences are minor, and likelihood of failure is very likely or likely, or likelihood of failure is somewhat likely, and consequences are significant or severe.
Tree Care Professionals Serving Communities Who Care About Trees www.WCAINC.com
21 Negligible (Consequence)-No personal injury, low value property damage, or disruptions that can be replaced or repaired.
Normal Tree Vigor-Overall tree health is good. Expected growth and foliage color for the time of year is observed.
Pathogen – causal agent of disease. Usually refers to microorganisms.
Possible – Failure may be expected in extreme weather conditions but is unlikely during normal weather conditions within the specified time frame.
Probable – Failure may be expected under normal weather conditions within the specified time frame.
Rare-The target zone is not commonly used by people or other mobile/movable targets.
Risk-The combination of the likelihood of an event and the severity of the potential consequences.
Risk Rating-The level of risk combining the likelihood of a tree failing and impacting a specified target, and severity of the associated consequences.
Root Plate – The structural roots and associated soil that make up the support area for a tree.
Scaffold Branches – Permanent or structural branches that form the scaffold architecture or structure of a tree.
Secondary Branches – Branches that emerge from the scaffold or other branches in a tree.
Severe (Consequences)-Serious personal injury or death, high-value property damage, or major disruption of important activities.
Significant (Consequences)-Substantial personal injury, moderate to high-value property damage, or considerable disruption of activities.
Structural Roots – Large roots emanating from the root collar that provide anchoring and support for a tree.
Targets-People, property, or activities that could be injured, damaged, or disrupted by a tree failure.
Time frame – Time period for which an assessment is defined.
Tree Care Professionals Serving Communities Who Care About Trees www.WCAINC.com
22 Tree Parts – Divisions of the overall tree examined individually as part of the risk assessment.
Uncorrected Lean – Tree with a trunk lean lacking upright growth in the upper canopy.

94 Appendix B Assumptions and Limiting
Conditions
1. Care has been taken to obtain all information from reliable sources. All data has been verified insofar as possible; however, the Consultant can neither guarantee nor be responsible for the accuracy of information provided by others. Standard of Care has been met with regards to this project within reasonable and normal conditions.
2. The Consultant will not be required to give testimony or to attend court due to this report unless subsequent contractual arrangements are made, including payment of an additional fee for such services as described in the fee schedule and contract of engagement.
3. Loss or alteration of any part of this report invalidates the entire report.
4. Possession of this report or a copy thereof does not imply right of publication or use for any purpose by any other than the person to whom it is addressed, without the prior written consent of the Consultant.
5. This report and any values expressed herein represent the opinion of the Consultant, and the Consultant’s fee is in no way contingent upon the reporting of a stipulated result, a specified value, the occurrence of a subsequent event, nor upon any finding to be reported.
6. Unless expressed otherwise: 1) information contained in this report covers only those items that were examined and reflects the condition of those items at the time of inspection; and 2) the inspection is limited to visual examination of accessible items without dissection, excavation, or coring, unless otherwise stated. There is no warranty or guarantee, expressed or implied, that problems or deficiencies of the tree(s) or property in question may not arise in the future.
7. Arborists are tree specialists who use their education, knowledge, training, and experience to examine trees, recommend measures to enhance the beauty and health of trees, and attempt to reduce the risk of living near trees. It is highly recommended that you follow the arborist recommendations; however, you may choose to accept or disregard the recommendations and/or seek additional advice.
8. Arborists cannot detect every condition that could possibly lead to the structural failure of a tree. Trees are living organ isms that fail in ways we do not fully understand. Conditions are often hidden within trees and below ground. Arborists cannot guar antee that a tree will be healthy or safe under all circumstances, or for a specific period.
9. Any recommendations and/or performed treatments (including, but not limited to, pruning or removal) of trees may involve considerations beyond the scope of the arborist’s services, such as property boundaries, property ownership, site lines, disputes between neighbors, and any other related issues. Arborists cannot take such considerations into account unless complete and accurate information is disclosed to the arborist. An arborist can then be expected to consider and reasonably rely on the completeness and accuracy of the information provided.
10. The author has no personal interest or bias with respect to the subject matter of this report or the parties involved. He/she has inspected the subject tree(s) and to the best of their knowledge and belief, all statements and information presented in the report are true and correct.
11. Unless otherwise stated, trees were examined using the tree risk assessment criteria detailed by ANSI A300 (Part 9)-2017 Tree Risk Assessment, a. Tree Structure Assessment.
