While there are multiple surface cracks in the bark that are typical of eucalyptus, this crack appears to be deeper in the wood of the tree. Roots • Lifting: Lifting of the surrounding soil and stones is clearly present in the area, as the tree has grown to a major size so has its roots. • Basal Rot: Rot is present at the base of the tree on the building facing side. Worms and other insects are present under the bark in this area and wood is clearly deteriorating. Soil/Growing Environment • Poorly Drained: Poor drainage in the area on the building facing side of the tree has likely contributed to the rot as water has been able to pool there, as oppose to the park facing side which is on the slope. • Girdling: With a limited growing area, some of the larger roots appear to be girdling other major roots, if not the tree itself. This will only continue as the tree grows. 2337 American Way, Hayward, CA 94545 Phone: 1.888.969.8733 1741 Leslie Street San Mateo,CA 94402 Fax: 510.881.5208 3207 Fitzgerald Road, Rancho Cordova,CA 95742 Web: www.arborwell.com Community Development Department 1 Planning Division — Cupertino Arborl el professional tree management CUPERTINO APPROVED CasAecommenf-016 ■ it Is myrplftpi In q at the Eucalyp us trees (68) located at Biltmore apartments, be removed entirely (including stumps and major roots); immediately.

If a major limb were to fail it would almost definitely fall either in a walkway area or on a residence. Roots • Small Growing Area: Roots are growing in a small area that is raised and surrounded by concrete. As roots are likely going below the concrete to continue and spread, this could lead to future damage. • Utility Damage: Roots could be in conflict with underground utilities; gas and sewer lines may be compromised. Soil/Growing Environment • Ivy: The presence of ivy all throughout the growing area means that a lot of moisture is retained around the base of the tree. With leaves shading out the soil, it takes longer for water to evaporate and as such it can sit on the tree for longer. This could have contributed to the fungal outbreak present. 2337 American Way, Hayward, CA 94545 Phone: 1.888.969.8733 1741 Leslie Street San Mateo,CA 94402 Fax: 510.881.5208 3207 Fitzgerald Road, Rancho Cordova,CA 95742 Web: www.arborwell.com Community Development Department 1 Planning Division — Cupertino Arborl el professional tree management cuPEarMecommendaLINDVED Case# - -016 pp I a ion um r(s LI s tree (65) located at Biltmore Apartments be removed entirely (including stumps and major roots; immediately.

More importantly, the major branch junction has some included bark which is a structural defect and can lead to limb failure. • Trunk: As mentioned above included bark is found at the main branch junction. The tree trunk is also incredibly close to the residence with the trunk only about a foot away from the building. Roots • Basal Rot: On the side of the tree closest to the building, fungus and insect life can be found on the base of the tree, decomposing wood. This decay is very concerning because as more and more of the tree decays the structural integrity of the tree becomes worse and worse making a failure more likely. Soil/Growing Environment • Ivy: Similar to Eucalpytus (65), the presence of ivy in the growing area means that a lot of moisture is retained around the base of the tree. With leaves shading out the soil, it takes longer for water to evaporate and as such it can sit on the tree for longer. This could have contributed to the fungal outbreak present. • Small Growing Area: Growing area is small for a tree of this size surrounded by concrete and building foundations. Could eventually lead to concrete, plumbing, or other damage caused by roots. 2337 American Way, Hayward, CA 94545 Phone: 1.888.969.8733 1741 Leslie Street San Mateo,CA 94402 Fax: 510.881.5208 3207 Fitzgerald Road, Rancho Cordova,CA 95742 Web: www.arborwell.com Community Development Department Planning Division — Cupertino Arborell.professional tree management tUPERTWecommendaM9VED Case# TR-2020-016 • c I „ FI s tree (67) located at Biltmore Apartments be removed entirely (including stumps and major roots); immediately.

Roots • Girdling: A root that is circling part of the trunk can slowly cut off the tree's vascular system as it squeezes the trunk, slowly growing over time and causing more damage as it grows. It has likely been growing this way since it was planted. • Basal Rot: Fungus found at the base of the tree is a sign of rot that can damage the structural integrity of the tree Soil/Growing Environment • Wood Chips/Piling: Wood chips are found in the planting area and while these are typically not a problem for trees and can be a good way to retain moisture in the soil, there is a bit of piling of wood chips around the base of the tree. This can hold moisture against the base of the tree for too long and could have contributed to fungal activity. 2337 American Way, Hayward,CA 94545 Phone: 1.888.969.8733 1741 Leslie Street San Mateo,CA 94402 Fax: 510.881.5208 3207 Fitzgerald Road, Rancho Cordova,CA 95742 Web: www.arborwell.com Community Development Department 1 Planning Division — Cupertino Arborl el professional tree management CUPERTINO APPROVED case Recommel016 • It is my*P,06mi"weiteoh)that the Eucalyptus tree (66) located at Biltmore Apartments be removed entirely (including stumps and major roots); immediately.

Soil/Growing Environment • Small Planting Area: In a small planting strip such as this between the building and the fountain, as the roots grow they can damage the foundation of the building as well as utilities such as plumbing.

As such, we opted for Acer rubrum and Quercus parvula, two species that do not pose those challenges. Both species do not grow nearly as tall as eucalyptus or have limbs that get as heavy. Therefore, they can grow up against these buildings and not pose as big of a risk if a limb breaks and falls. Furthermore, replanting with these two species provides both deciduous and evergreen trees to the property. Acer rubrum has a beautiful fall leaf coloration, and would add to the overall aesthetics of the property. Quercus parvula is green all year long, ensuring that not all the trees will be barren in winter. Additionally, there are already multiple Acer rubrum planting on the property, so these trees would add to this already existing population on site. Overall replanting with eucalyptus is ill advised as it would lead to problems in the future, while Acer rubrum and Quercus parvula are excellent replacements as they do not pose the same hazard risks and improves the overall landscape aesthetics. The olive trees that are to be removed will be replaced with Betula nigra instead of more olive for a few reasons. First, the olives are doing poorly where they are planted. Multiple limbs are in decline and overall the trees do not look good. As such, if we planted more olive trees, the same health issues would likely come up again as the trees mature. Furthermore, these trees are messy when they drop fruit, so replanting with a species that does not produce fruit will help with maintaining the property. As such, we have choses Betula nigra to replant with. With other birch trees already growing on the property, these trees make a great addition to the species makeup on site. Additionally, the other birch trees growing on site are vigorous and healthy, suggesting that these birch will also do well. These trees also do not produce fruit, so maintaining the area where they grow will be much easier that with more olives. With all this in mind, we believe it best to replace the olive trees with Betula nigra instead of more olives as it will be more beneficial to the landscape and residents in the long term.
