Dear Kevin,
This revised arborist report addresses the proposed residential development at 20807-20883 Stevens Creek Blvd, Cupertino. This revision addresses comments from the city and their contract arborist. Changes to the report are highlighted in red text for visibility.
For this report, I referenced the following:
• Email communication with Catherine Tarone, Cupertino Planning, on April 8, 2024 • City of Cupertino Municipal Code Chapter 14.18 (Protected Trees) and 19.28.120 (Privacy Planting)
• Title survey by Slooten Consulting, Inc. (undated)
• Plans by CBG Civil Engineers (December 24, 2025)
• Landscape plans by GATES + Associates (December 24, 2025) • Planning & city consulting arborist comments (September 2 & 13, 2025)
The definitions of “protected tree” in the ordinance (14.18.050) covers several categories, including “heritage trees”, “mature specimen trees”, “privacy planting”, and “development trees”.
For this property, the defining category is “development tree”. Per my emails with the city, “any property with a P in front of the zoning means Planned Unit Development and all trees on these properties are considered Development Trees”. Therefore, every tree on the property is considered protected.

Michelia Arboriculture, LLC | 925-515-1362 | [email protected] Site & Project Summary
The project site is a large commercial property made up of four separate parcels, for a total of
6.93 acres. To the west is a Whole Foods, church, and single-family residential properties; to the right is a commercial property. Nine separate structures are roughly placed in 2 parallel rows in a north-south orientation; the remaining area is made up of parking lot and relatively small landscape planters. One dedicated entry way bisects the property and connects Alves Drive to Stevens Creek Blvd, but it also shares a second entryway – at the southeast corner – with the adjacent plaza. The single-family residential properties at the northwest corner harken to the transition zone to more residential properties to the north. The current use is a mix of commercial purposes, including food businesses in the southeast building and office or medical uses in the remaining buildings. In addition to Apple offices, the site also houses Cupertino and Burbank Sanitary Districts.
I included 269 trees in my tree inventory,
including 18 off-site trees. The high tree
count is possible only because of the density
of the tree plantings, which feature many
trees in crowded landscape areas that are
too small to support their mature size (Figure
1). There is a low to moderate degree of
species and size diversity in the tree canopy.
23 species were recorded, including three
California-native species (coast live oak,
coast redwood, Monterey pine). The coast
redwood (Sequoia sempervirens) is the most
abundant tree with 75 individuals, making up
27.9% of the total. It is distantly followed by
37 Japanese maples (Acer palmatum,
13.8%) and 32 crape myrtles (Lagerstroemia
CV, 11.9%). The City-owned street trees
consist of 6 Callery pears (Pyrus calleryana),
while the other 12 off-site trees include
Canary Island pines (Pinus canariensis),
coast live oaks (Quercus agrifolia) and
Brazilian peppers (Schinus terebinthifolia)
along the west property line.
The proposed project will clear the property
to build a total of 122 units of housing,
including 66 single-family detached homes and 56 multi-family units (in buildings of eight units each). The multi-family buildings are located on the south portion of the property, transitioning to single-family on the north side closer to the other single-family properties. The new homes and Figure 1. Many trees are planted in small areas that may support one mature tree, at most (sometimes 0 trees; #171- 173 shown above).

Michelia Arboriculture, LLC | 925-515-1362 | [email protected] associated driveways and utilities will essentially
take up the entire site, requiring grading that
basically spans property line to property line.
All existing features, including almost every tree,
will need to be demolished to complete the project.
It is my opinion that 249 on-site trees will need to
be removed, which only leaves two remaining trees
within the site boundaries. The six Callery pears in
the frontage sidewalk were originally proposed for
removal on account of poor structure and species
choice, but they will be retained per city request
(Figure 2). The efforts of tree preservation are thus
focused on a total of 20 trees within or adjacent to
the site. Design changes were made to provide
additional space along the west property line to
reduce impact on those trees. The high number of
tree removals means that mitigation requirements
are high – I advise against trying to squeeze as
many trees on site as possible. For long-term
success, appropriate growing areas should be
provided to avoid the same problems that affect the
site today.
Assumptions & Limitations
The trees were not surveyed; their locations were approximated by me based on the survey.
The accuracy of the tree protection recommendations thus may vary since they are based on estimated tree locations. For greater accuracy, survey the off-site trees. Precise locations of the on-site trees are less important because they will still be removed.
The tree assessment provided by this report represents a snapshot in time of the trees’ conditions. It is not possible for arborists to predict long-term tree condition. Changes in weather/climate or environmental alterations can present unexpected impacts on the health and stability of trees (e.g. storm events, severe drought or heat, landscaping, repairs, irrigation reduction, other changes especially on adjacent properties). Specifically, Monterey pines are unpredictable in their rate of decline and may suddenly die within a few months. Because of these reasons, it is also not possible for arborists to guarantee that trees will not fail. To live with trees means to accept a certain level of risk, which can only be fully eliminated by removing the trees.
Figure 2. Callery pear #233 is one of the 6 sidewalk
trees. They were originally proposed for removal but
now remain per city request in cut-outs that are similar or larger to the existing cut-outs.

Michelia Arboriculture, LLC | 925-515-1362 | [email protected] Observations & Discussion of Tree Impact
Most of the site is covered by buildings and hardscape. Landscape areas are mainly restricted to narrow planting strips between the buildings and walkways/parking. Tree distribution is good, with large trees in larger connecting planting areas. Smaller trees are squeezed in between buildings and in raised planters. In spite of the limited landscape area, the total number of trees is exceptionally high at 269 - which is achieved through overplanting, resulting in overly crowded trees. This approach to tree planting is common in office & industrial parks, especially if there are minimum requirements for tree planting. If enough space were given to allow the trees to grow to their full size, there would be far fewer trees on the property. Unfortunately, high tree density usually translates to high tree removals during construction projects. The 269 trees are divided into 23 species, outlined in the table below, with coast redwoods being the dominant species. The California-native species will be briefly discussed.

Native species
There are three California-native species on
the site: coast live oak, coast redwood,
Monterey pine. The most abundant species is
coast redwood (Sequoia sempervirens), which
is native to the coast and not Cupertino. In
their natural habitat, they receive a significant
amount of water through fog. In warmer inland
regions like Cupertino, redwoods must be
sustained by high quantities of water which is
at odds with state & local water restrictions
(Figure 3). A spectrum of drought stress is
reflected in tree health in the on-site trees –
the healthy redwoods (#235-244) at the
southwest end are relatively protected by two
buildings, while the redwoods at the east
property line are more exposed and stressed.
Some of the redwoods on the east side have
died or were pruned aggressively to clear the
power lines. Since they are large trees, they
also need more of their root systems preserved
to remain healthy and stable after construction.
Unfortunately, due to the density of the new
development, adequate space cannot be
provided. All 75 redwoods will be removed for
construction.
There is only one Monterey pine (Pinus radiata), found at the north property line, which will also be removed as part of the project. Monterey pines are also native to the coast, so they easily succumb to drought stress and beetle attack in warmer regions.
Coast live oak (Quercus agrifolia) is the only species that is native to this specific region, making it well adapted to dry and hot summers. The two oaks are both off-site, about 4’-10’ west of the fence (#260 & 264, Figure 5). These two trees are among the 20 trees that will be preserved.
Anticipated construction impacts
The roads, homes, and utilities proposed for the project almost cover the entire property. It is expected that all existing features will be demolished, and the site will be graded nearly property line to property line. Silva cells will be incorporated into the new stormwater system; the structures are designed to support surfaces while providing a belowground reservoir for uncompacted soil and water. Unfortunately, while they benefit newly planted trees, they are often at odds with existing trees. Silva cell installation requires excavation and ends up removing a lot of tree roots (Figure 3). With infrastructure requirements, it’s not possible to Figure 3. The coast redwoods are the dominant tree but
are not native to the area and have high water needs.
Ample irrigation, like for turf, is needed to maintain health. (Trees #130-132 will be removed due to proposed
buildings and Silva cells)

Michelia Arboriculture, LLC | 925-515-1362 | [email protected] provide enough above- & below-ground space to save the on-site trees. Thus, all but two on-site trees will be removed (total 249 on-site trees). The remaining two on-site trees are Canary Island pines #142 & 143 at the northwest corner. The primary impact on the two trees will be from hardscape installation – encroaching as close as 3’ from tree #143, and 6’-12’ from tree #142. Although a 3’ clearance sounds excessively close, there is a large utility box within this area, and a sidewalk further away. Both features may have limited root growth into the area that will encompass the new sidewalk and walkways. Canary Island pines are also tolerant of root loss, especially when they are healthy like these two specimens. The contractors should switch to hand digging near the trunk, which will allow for more careful excavation around larger roots.
An arborist should also be retained to review the roots before they are cut.
Additionally, there are six Callery pears growing in sidewalk planters along the Stevens Creek Blvd frontage (Pyrus calleryana, Figure 2). They include trees #2, 5, 7, 8, 10 & 233; I assume these are City-owned trees. The pears are relatively young trees but are close to their maximum height. Although this tree has excellent fall color and attractive flowers, its benefits stop there.
The species is notorious for its poor structure, as evidenced by multiple narrow stems that originate from the same height on the trunk. As each stem grows thicker, it pushes on its neighbor and the weakest stem(s) will break. Additionally, it’s highly susceptible to fire blight, a bacterial disease spread by rain & pollinators. The disease kills branch tips and continues to progress lower in the tree. To manage this disease, the trees must be regularly sprayed before infection begins, and branches must be pruned several inches below the affected area. Over time, Callery pears are often disfigured by management pruning. These trees were originally proposed for removal because of their structure and species, but they will now be retained per city request. Based on
the latest landscape
plans, the new
sidewalk planters will
be the same size or
slightly larger. Since
there is evidence of
concrete lifting and/or
repair, excavation
should proceed by
hand around larger
roots. An arborist
should be consulted for
recommendations if
roots > 1” diameter and
larger are encountered.
The majority of the tree
protection efforts are
focused on the 12 off-
site trees along the
Figure 4. A row of Canary Island pines grow behind the Whole Foods building; their roots are likely to grow into the property (#250-254 shown above). The landscape area should be fenced off up to the parking lot & an arborist must monitor storm drain work next to the trees.
Proposed residential development at 20807-20883 Stevens Creek Blvd, Cupertino September 5, 2024 (revised 12/18/25) 0030-001 Page 8
Michelia Arboriculture, LLC | 925-515-1362 | [email protected] west property line. Minimizing impact to off-site trees is crucial – legally, a property owner does not have the right to harm their neighbors’ trees. There are nine Canary Island pines planted next to the Whole Foods building, approximately 6’ from the property line fence (Pinus canariensis, trees #250-258; Figure 4). A short concrete border is visible below the fence, but its depth is not clear. On the subject property, there is a tall retaining wall by trees #250 & 251 and a wider landscape area by trees #252-258. If the concrete border extends several feet below grade, it may act as a root barrier, but roots will often return to the surface once they bypass the barrier. The existing parking lot may have limited root growth – the subgrade is normally very compacted and unattractive for roots. Over time, as asphalt degrades and becomes more permeable to water, roots may start to extend under the pavement. To be safe, I assume that roots will have grown past the property line into the landscape area.
The adjacent street was originally much closer to the property line, which would have damaged the roots of the pines. I recommended that the design be changed to preserve the existing landscape area, thereby protecting most of the roots on the subject property. While the road was shifted, a new storm drain will run parallel to the property line through the landscape area.
Because of site constraints, it may be difficult to further relocate this line, especially with four other utilities running through the street. I highly recommend exploring methods that do not involve open trenching to avoid damaging large roots; excavation should only proceed with an arborist on site. The latest grading plan also shows a 3.5’ tall retaining wall at 5’ from the property line. This puts the new wall just outside the existing landscape area in the current parking lot. The wall will be ~11’ from the trees, which is an acceptable distance especially since their roots have already been affected by the asphalt. There are no substantial changes to my recommendations, except that an arborist should also be present when the wall footing is excavated.
North of the pines are two coast live oaks (Quercus
agrifolia, #260 & 264, Figure 5). They are young and
healthy, therefore more resilient to construction
impacts. Proposed grading will start at the property
line with the following impacts:
• Tree #260: >3’ drop over about 16’; grading
starts 8’ from the tree. Impact is low, no
changes to recommendations (Should the
contractors encounter roots > 1” diameter by
tree #260, they should consult an arborist for
recommendations.)
• Tree #264: 1.5’ drop starting 4’ from the
trunk. Impact is likely acceptable, but an
arborist shall monitor the process to prevent
unnecessary root damage.
Figure 5. Coast live oak #260 overhangs the site –
it should be protected with temporary fencing.

Michelia Arboriculture, LLC | 925-515-1362 | [email protected] The last off-site tree is a Brazilian pepper at the north end of the site (Schinus terebinthifolia, #266, Figure 6). This species is
notoriously weedy, in part due to
its seed production and highly
variable habit. It can grow as a
vine, shrub, and tree - all on the
same plant. This specimen is
more like a grove of multiple
volunteers. The Brazilian peppers
I reviewed for this project have
disproportionately high numbers
of trunks relative to the size of
their canopies. If the trees had 1/3
to 1/2 of their current trunks, they
would still have a similar-sized
canopy – instead, each trunk only
supports a smaller percentage of
the total foliage. The species has
a good tolerance to construction
impacts, but I still recommend
having an arborist on site while the road is graded next to the tree. Minor grading is expected, with a half foot drop down from the property line. Some root pruning is likely to occur, so supplemental irrigation is needed to mitigate stress that may result. The method of watering will likely vary depending on the stage of construction, e.g. using water trucks early on when water lines are not complete.
In addition to being cautious during excavation, the adjacent landscape areas must also be protected with temporary fencing once excavation is completed – this applies to any tree that is retained. While it may seem insignificant, construction can cause a lot of damage to trees even through indirect activities. Because the site is level and accessible, the contractors are likely to spread their materials and equipment throughout the whole site. Those activities can compact and contaminate soils within the trees’ root zones. When soil is compacted, space for roots, oxygen, and water become limited. Over time, tree health can decline as the roots struggle to access the resources they need. It can take many years for the negative impacts to show, at which time it is usually too late (and very expensive) to reverse the impacts. The simplest way of protecting the soil and roots is to install a temporary chain-link fence to create a no-impact zone around the trees. Alternatively, a combination of wood chips & steel plates or thick plywood may be used. The goal of these methods is to create a buffer over the soil and roots. Other alternatives can be considered but should be discussed with an arborist. Since the fenced area serves as a “tree protection zone”, any work that requires digging should be kept outside of the fence. Otherwise, an arborist needs to review and approve the work so that the appropriate measures can be taken to maintain low impact.
Figure 6. Brazilian pepper #266 is a cluster made up of several separate trunks; the hedge on the property also includes pepper stems. An arborist shall be on-site to monitor grading next to this cluster.

Michelia Arboriculture, LLC | 925-515-1362 | [email protected] Proposed replacement trees
The September 2, 2025 arborist peer review includes this comment on page 3: “It was not clear whether a certified arborist has assessed whether replacement trees can be reasonably planted on the subject property. Given the overcrowded planting in the existing conditions, replacement on-site at current or higher density is not appropriate.”
The proposed planting plan includes 65 trees that will become large at maturity (Armstrong maple, ginkgo, live oak, Chinese elm). Smaller trees are disregarded for this discussion. The largest oaks are placed together in a courtyard, where there is more space compared to landscape areas between buildings and hardscape. None of them will have an ideal amount of space, since new utilities and hardscape must also be installed throughout or adjacent to landscape areas. This is the unfortunate reality of tree planting requirements in urban or suburban developments, where there are many demands on space. It is my opinion that the number of trees that have been specified is a reasonable compromise and offers a reduction in tree density (currently, there are 129 large trees on the site).
Tree Protection Recommendations
Design Phase
• As the design progresses, ensure that the native grade is not disturbed within the temporary fencing area that is highlighted in the Tree Protection Plan that accompanies this report. o If encroachment is needed within the fenced area, discuss the impacts with the Project Arborist before finalizing the design.
o Additional tree protection measures may be needed, including but not limited to:
digging by hand or with air/water-assisted methods; providing supplemental irrigation; arborist monitoring during excavation. If the measures are not feasible, the trees may need to be removed.
• If the off-site trees are surveyed, the Project Arborist shall review updated plans to determine whether the tree protection recommendations still apply. • Include a note in construction documents (on relevant sheets) that less invasive methods of excavation may be needed around trees #250-259 if significant roots are encountered within 12”-18” of existing grade. Methods may include but are not limited to air/water-assisted excavation tools, directional boring, hand digging, etc.
Pre-Demolition Phase
• Contractors:
o Inform all contractors and subcontractors of the significance of protecting the off-site trees, as the financial consequences for tree damage may be significant (both in city fees and claims from off-site tree owners). A pre-construction meeting may be needed to review the tree protection measures and work plan before demolition begins.
o Keep your Project Arborist informed of the construction schedule, especially the excavation phases where monitoring or recommendations are needed.

Michelia Arboriculture, LLC | 925-515-1362 | [email protected] • Temporary tree fencing:
o Before equipment arrives on site, install temporary 6’ chain-link fencing around trees #2, 5, 7, 8, 10, 142, 143, 233, 252-258, 260 & 264 as noted on the Tree Protection Plan.
o Leave additional fencing by tree #252 so the protection area can be expanded to include trees #250 & 251 after demolition is completed. o If the fencing location(s) will obstruct construction access, discuss other options with the Project Arborist.
o The fencing shall stay upright and secure throughout the project. To modify the fencing, consult the Project Arborist to determine what substitute tree protection measures are needed to provide the same degree of protection. Fencing shall not be moved or adjusted without the Project Arborist’s approval. • Pruning: Limit clearance pruning to the bare minimum, i.e. enough to just clear the air space needed for construction. Pruning shall be done by a tree service with a certified arborist on- staff, before construction begins.
• Wood chips, optional: If desired, spread the wood chips generated by tree removal within the fenced areas. The wood chips will conserve water and contribute nutrients to the trees; they can also be left in place after construction.
Demolition Phase
• Remove every tree EXCEPT trees #2, 5, 7, 8, 10, 142, 143, 233, 252-258, 260 & 264 (249 trees to be removed; 20 trees to remain).
• After demolition is completed, extend the tree protection fencing to enclose trees #250 & 251 as noted on the Tree Protection Plan.
Construction Phase
• The Project Arborist shall be on-site during storm drain and retaining wall excavation by Canary Island pines #250-259. If significant roots are encountered within 12”-18” of existing grade, less invasive methods may be needed (e.g. air/water-assisted excavation methods; directional boring, hand digging). Once the storm drain is completed, fencing must be immediately reinstalled.
• The Project Arborist shall also be on-site during grading for the road by coast live oak #264 and Brazilian pepper #266. Regularly moisten the soil by this tree with methods available during that phase of construction (e.g. water truck, soaker hoses). • If roots > 1” diameter are encountered during excavation or grading by coast live oak #260, consult the Project Arborist for recommendations.
• For Canary Island pines #142 & 143, hand excavate along the sidewalk within 8' of trunk.
Consult the Project Arborist for recommendations before root pruning. • For sidewalk pear trees #2, 5, 7, 8, 10 & 233, hand excavate around roots > 1” diameter or larger. Consult the Project Arborist for recommendations before root pruning. • All root pruning shall be completed with sharp tools (hand pruners, loppers, handsaw, Sawzall, or circular saw), making the smallest possible cut – perpendicular to the length of the root rather than at a diagonal. Roots must then be covered and kept moist until the soil is backfilled.
• At any time, if damage occurs to any tree, immediately consult the Project Arborist for recommendations on how to mitigate the damage.

Michelia Arboriculture, LLC | 925-515-1362 | [email protected]
Post-Construction Phase
• If the Project Arborist deems it necessary during construction, supplemental irrigation should be provided for one growing season after construction is completed (~9 months). A temporary option with soaker hoses may be used. The hoses should be laid out as close to the edge of the tree canopies as possible. Leave them at a slow drip rate for 8 hours once a month (overnight is ideal). The irrigation off-sets water stress that may result from root pruning.

Michelia Arboriculture, LLC | 925-515-1362 | [email protected] Appendix 1: Tree Inventory Table
The tree inventory table includes individual tree data as required by the City of Cupertino. The data is explained as follows:
ID # # assigned to each tree, correlating with a metal tag affixed to their trunks. Off-site trees are not tagged if their trunks are not accessible from the property; tags may be applied to the property line fence if feasible. Note: tree #105 is a shrub and was omitted from the report.
Species Common name; for botanical name, see table on page 4.
DBH Diameter at Breast Height (4.5’ above ground) in inches; trunk is measured with a diameter tape. For off-site or inaccessible trees, the trunk size may be visually estimated instead.
Health Health and vigor of the tree. Ratings are broken down into:
• Good: The tree is growing well with vigor appropriate for its age – canopy is full with good color. Pest or disease issues may be present but have low impact on the tree.
• Fair: The tree is showing signs of stress, exhibited as sparseness of canopy, change in foliage color, and minor-moderate signs of pest or disease issues. It can recover as long as conditions naturally improve. • Poor: The tree is stressed with tip dieback; it is unable to overcome pest & disease issues. Immediate long-term intervention and care is needed to avoid decline to the point of non-recovery.
• Very Poor: The tree has significant issues and has declined so far that it is unlikely to recover.
• Dead: No life remains in the tree.
Structure Architecture & defects of the tree. Ratings are broken down into:
• Good: The tree has ideal trunk & branch architecture. • Fair: Branch defects, poor attachments and decay may be present, but they can be mitigated with 1-2 pruning cycles (over 3-5 years). • Poor: Defects cannot be mitigated without long term management (10+ years); support systems like cabling and bolting may be needed in conjunction with pruning to reduce risk to the property. • Very Poor: The tree has significant issues that cannot be corrected and may be a hazard to the property.
Dripline The canopy (“dripline”) radius is visually estimated in feet in each cardinal direction (north, east, south, west).
Appraised
Value
For trees > 36” diameter, appraised values were estimated for mitigation purposes.
An estimate of the value of each tree is obtained based on best practices, using the Trunk Formula Technique outlined in the 10
th Edition of the Guide for Plant
Appraisal by the Council of Tree & Landscape Appraisers (CTLA). The cost to replace a perfect specimen of like-size is calculated, then depreciated by the subject tree’s current health, structure, form, factors that are inherent to the species and property, and external factors that are out of the property manager’s control.
Notes Proximity to the project’s improvements, and the anticipated impact based on tree condition, species tolerance to disturbance, future longevity, etc.
Actions Includes recommended actions based on impacts, including tree protection measures. Includes reason for removals per CMC 14.18.180 Review, Determination and Findings.

Michelia Arboriculture, LLC | 925-515-1362 | [email protected] Removal rationale per CMC 14.18.180 Review, Determination and Findings Per the city’s completeness comments, the tree inventory table was updated with the reason for tree removal, according to code section CMC 14.18.180. The descriptions are as follows:
1. That the tree or trees are irreversibly diseased, are in danger of falling, can cause potential damage to existing or proposed essential structures, or interferes with private on-site utility services and cannot be controlled or remedied through reasonable relocation or modification of the structure or utility services;
2. That the location of the trees restricts the economic enjoyment of the property by severely limiting the use of property in a manner not typically experienced by owners of similarly zoned and situated property, and the applicant has demonstrated to the satisfaction of the approval authority that there are no reasonable alternatives to preserve the tree(s).
3. That the protected tree(s) are a detriment to the subject property and cannot be adequately supported according to good urban forestry practices due to the overplanting or overcrowding of trees on the subject property.
4. That the mature specimen trees with single trunk between twelve inches DBH and twenty-four inches DBH, or multi-trunk between twenty-four inches DBH and forty-eight inches DBH in R1, A1, A, RHS, and R2 zones will be replaced by planting a replacement tree and/or by contribution to the City’s Tree Fund. Not applicable to property.
In the “Actions” column of the tree inventory table, a number was assigned with a brief explanation as to how the removal fits into one of the categories. For example, “1-dying” indicates a tree that falls under the first removal category – one that is in very poor health and will not recover. Most of the trees fall under “2-economic use” since they will be difficult to preserve in the face of the proposed project.
