Below is my findings. Assignment: Assess and report on the health, stability, and structural integrity of one Monterey Pine at Unit#634. Address concerns about subject tree. The subject Monterey Pine tree anchoring roots are causing uplifting to the adjacent sidewalk & Unit#634 front patio creating trip hazards. This report was generated and performed as a ground visual inspection only. No scans, such as tomography scans, were used during this evaluation. Observations: The subject Monterey Pine tree "A" is located in front of Unit#634 at the Villages at Cupertino apartment complex facing Stelling Road. Pine Tree "A" is approximately 50 feet tall and has a canopy that stretches out to approx... 40 feet wide. The trunk diameter is 29 inches. Tree is about 50 years old. It has reached maturity growing within the confines of the planter. The tree was planted about 10 feet from Unit#634 front patio & building foundation. Monterey Pine trees are considered large sized trees that can grow to approx.. 100 feet tall and at least 50 feet wide given ideal growing conditions. They need a growing location that can provide the necessary space to grow to such a large size. Anchoring roots within 20 feet of a mature Monterey pine can become problematic to nearby hardscape. Hardscape can become damaged &/or lifted due to root expansion. Monterey Pines require large, park size planting locations where roots can grow unencumbered, free of hardscape obstacles.

It is showing the usually signscorpes �and disease so common to Monterey pines when growing out of their ideal growing environment. Monterey Pines tend to be shorter lived in the South Bay; about 50 years or so due to poor growing conditions. Ideally, Monterey pines want to be growing within the fog belt of the coast, in sandy soil. Pine "A: is growing within a 10 foot x 10 foot planter. The trunk has about 2 feet of space on the sidewalk side of the trunk and about 10 feet on the building side of the trunk. Due to the limited rooting space of Pine "A" surrounded by Unit #634 building foundation, patio & sidewalk, this pine has been forced to grow under the hardscape in order to develop proper anchorage. Unfortunately by doing so the sidewalk & patio hardscape have become a problem over the years with concrete lifting. Grinding down risen concrete seams has been employed in the past roots have raised the hardscape to a steep angle currently and has become dangerous to negotiate the slant and safely pass through without risk of a trip and fall. I have been informed from management that there are plans to remove and replace the surrounding sidewalk & patio to alleviate this hazard. Rerouting the sidewalk around the root flair to give it more rooting space is not practical and would limit the amount of space for residents to walk safety. My concern is that the anchoring roots under the existing concrete would likely be damaged or removed to allow for proper sidewalk depth. Root pruning large anchoring roots within 10 feet of the tree trunk is inherently dangerous for the future health & stability of Pine "A". It is recommended to remove Pine "A" at the same time as the concrete replacement to avoid any future health &/ or stability issues. Pine "A" would will likely decline further anyways from any root cutting due to its age, drought, over health, disease and insect history. It's better to get ahead of it by planning for its removal and replacement now. Recommendation: It is recommended to remove Pine "A" and replant with 1 —24 inch box Saratoga Laurel & 1—24 inch box Strawberry Madrone (see replacement plan on page 5) Arborists are tree specialists who use their education,knowledge,training,and expertise to examine trees,recommend measures to enhance the beauty and health of trees,and attempt to reduce risk of living near trees.Clients may choose to accept or disregard the recommendations of the arborist,or to seek additional advice.
