l�e: Dead Tree Removals at 10161�ubb Road, Cupertino, CFAa�;=���'���� _ __ ___�._�_.�_� ___
�.:��,� i�i•�r��y��
To whom it may concern,
This letter intends to address two (2) Betula pendula (European white birch) located on the front
building-side planting area between the building and parking lot on the 10161 Bubb Road property
in Cupertino, California. Please see Exhibit 1.1 for the relative locations of the subject trees
indicated as red dots, and for the locations of the replacement trees. The trees are dead and require
removal.
Metrics for the dead birches are found in the following table:
� . . �- � . - . � -. �
A Euro ean white birch Betula endula j 8" 25" . 25' 15'
B Euro ean white birch Befula endula 9" 28" 30' 15'
The trees were detennined to be dead due to their extensive loss of foliage, severely desiccated
foliage,and lack of any green growth(see Exhibit 1.2). A test for live cambium tissue had negative
results. White birch are deciduous trees and should have a full crown throughout the surruner inonths.
The exact cause of death is likely due an Agrilz�s anxius (bronze birch borer) infestation linked to
severe water stress associated with the current regional drought. `
Although the trees were provided supplemental water throughout the suimner inonths with two (2)
bubblers each,white birch are known for their poor tolerance of drought. The water stress was caused
by the prolonged hot weather along with being next to radiant black asphalt and no rain for an entire
year. As an individual continues to be stressed,it then becoines susceptible to secondary infections
and pest infestations. Birch trees stressed by factors such as sustained drought are especially
susceptible to attacks by the bronze birch borer. Under stress,they have a reduced ability to acquire
and distribute water and carbohydrates throughout their canopy which leads to reduced tree defense
against the borer larvae.
Adult beetles feeding on the leaves of trees cause little dainage to overall tree health. However,the
passageways under the bark tissue created by the larvae cause significant damage to trees. These
passageways disrupt the transport of water and nutrients in infested trees. The initial symptoin is
often branch dieback at the top of the tree,as seen in other birch trees onsite. If the tree continues to
decline, dieback extends down into major branches and eventually into the main stem.
These trees will be removed and replaced. Removing dead trees does not require a tree removal
permit prior to its removal pursuant to Section 14.18.140 Paragraph B of the City of Cupertino's
Municipal Code;however,a subsequent application must be filed within five(5)working days.

The trees will require replacement,selected by the Apple arborist to ensure optimal structure,health,
and no girdling roots. The selected trees will then be trained from an early age as needed to optimize
branching structure, extending the aesthetically and structurally sound lifespan of the trees. The
proposed replaceinents are two (2) 36-inch box Quercus robur(English Oak)in the same locations
as the reinovals.
Please review this information and contact me with any questions or concerns regarding the
