The Coast Live Oak (Quercus agrifolia) is located on the west side of property in front
yard. (Appendix A: Site Overview)
It is approximately 40 feet tall with a diameter of 20 inches measured at 4.5 feet above
grade and a canopy spread of 30 feet.
Targets include two occupied dwellings. (Appendix B)
The base of main stem is riddled with cavities, deadwood, root rot, decay and Ambrosia
Beetle activity. Canker and slime flux are present as well.
These are all indicators of internal decay.
This weakens the structural integrity and the chances of failure are great.
This tree is damaged to the extent that it cannot be feasibly restores.
It is seriously diseased and has a short life expectancy. (Appendix 131)
RECOMMENDATIONS
Analysis of this data clearly shows that this tree is imminently hazardous and an imminent
threat to the health, safety and general welfare of persons and the house/property, which
requires immediate action to abate and should be removed and replaced with a more
appropriate species. Replacement tree will be one 24" box Olea europaea wilsonii and
customer will pay in lieu fee for the second 24" box requirement. There is no space for
additional 24" box tree to be planted. Customer will pay in lieu fee as stated above.
