Re: Tree Committee Agenda Report Î 3490 Empresa Drive
There are two existing London Plane trees for which Staff requested the Tree Committee
to provide feedback regarding potential preservation. I would like to address each of these
two trees and discuss some of the challenges and concerns with potential preservation.
Tree #148
As noted in the arboristÓs report, this London Plane tree is located in an exceptionally small planter that is
directly over the fire water supply mainline for the existing building. The arborist recommends removal of this
tree even without the proposed project, as it is out of room for roots and has the potential of breaking the
main fire water line. The tree also has a severe lean and has begun to crack the adjacent concrete curbs.
The tree leans over an existing drive isle and would be directly over the proposed building. We believe this

tree to be a safety concern both in its existing condition as well as the future planned building for occupants
and their vehicles. The photos below illustrate our specific concerns.
Tree #148 leans over drive aisle. Fire water main line connection @ street runs directly under tree.

Tree #149
As noted in the arboristÓs report, this London Plane has some minor flaws structurally and bends with its
weight toward Empresa Drive. This tree has a severe lean over the public right of way and sits directly where
all of the public utility lines will enter the proposed building. The tree is very close to a concrete curb which it
has already lifted and cracked. We believe these problems will worsen if the tree is not removed. The photos
below illustrate our specific concerns.

Conclusion: For the removal of tree #148 and tree #149, a compensatory replacement ratio of 2:1 is
proposed so two trees will be replanted for each of these two removed trees.
