Observed –
#1 – (1 tree) Manna Gum – Healthy tree. Large tree. Close to existing building. Top of slope
with lots of room for roots.
#2 – (1 tree) Red Flowering Gum – Large broadly spreading tree. Very healthy. Lots of room for
roots.
#3 - (5) – California Pepper – Smaller trees, fairly young. Trees are yellowed and somewhat thin.
Vary in height.
#4 - (1) – Jacaranda – Tree is on the top of the slop Sprawling tree. Tree branches are nearly
touching the building. Tree is dormant.
#5 – (1) – Ash – not found
#6 – (2) – Ash – The largest of the two has narrow stem angles with included bark. Smaller tree
has a somewhat thinner canopy. They are close to the top of the slope with lots of room for roots.
#7 – (1) – Coast Live Oak – Tree is in good health with good color and growth. Larger tree. Very
broad canopy that is well balanced.
#10 – (2) – London Plane – These trees are planted by the stairwell. One is in a narrow planter
and the other is near 4 electrical vaults. Roots can be a problem. Trees are dormant.
#11 – (7) – Purple Leaf Plum – Vary in size. Some are planted in very narrow planters where
roots can be a problem. Most of these trees have narrow crotch angles, included bark and
crowded branches. I noted cankering on some of the limbs. I also noted some that have
sunburned trunks. Some have surface roots. At least one has symptoms of borers.
#14 – (4) – Silver Doller Eucalyptus – All planted in parking planters. Large trees. Overall good
canopy color and vigor. One of these trees has a large gall at the base.
#17 – (1) – Mimosa – Sprawling canopy. Surface rooting tree. Tree is dormant.
# 19 – (1) – California Pepper – Large tree. In good health with good color and vigor. Large
planter with room for roots.
#16 – (1) – Coast live Oak – (mislabeled as California Pepper #19, on plan) – tree is close to the
two Silver Doller Eucalyptus (#14) In current parking planter. Healthy tree. Good growth.
Reason for removal – All of these trees are in the direct footprint of the proposed patient tower or
its appurtenances (utilities, walkways, reconfigured parking lot etc.).

*Assessment was made with observation, history and sound arboricultural and horticultural knowledge. It is
always possible that other, or different problems exist that may contribute to the destabilization, decline and
death of trees. Further evaluation may be warranted if the steps above do not work. Construction activities can
seriously disrupt roots and soils and lead to long term problems that may directly or indirectly cause a tree to
decline and die.
This is a London Plane tree. The close proximity to the electrical vaults will eventually be a
maintenance problem. This tree and all those in this section are directly in the way of the
building or its appurtenances.
