RE: Supplemental Arborist Report for trees at 1655 De Anza Blvd., Cupertino, CA.
Dear Joshua,
Thank you for contacting Davey Resource Group (DRG) regarding your project listed above. In support of your objectives, Davey Resource Group is providing you with this letter regarding a supplemental arborist report to support the previous arborist report by Ray Morneau, dated August 2025 and updated March 2026.
The inspection and tree protection measures at your project site to help ensure the resilience and longevity of the trees beyond construction.
A DRG International Society of Arboriculture (ISA) Certified Arborist #WE-14060A conducted the site visit on June 4, 2026. Five (5) new trees were assessed and sixty four (64) trees were re-assessed for a total of sixty nine (69) trees. DRG conducted an additional site visit on August 5, 2026 to re-assess the ten (10) remaining trees on the property. There are a total of seventy nine (79) trees assessed. DRG assessed and developed a tree protection plan for specific trees identified by the client and the City of Cupertino as related to the alternative proposed development at 1655 De Anza Blvd. in Cupertino, CA.
Trees #242-252 have different tags vs tree #’s due to the trees being physically tagged with the numbers #452, 488-498 on them rather than the previous number system that Ray used.
The remaining ten (10) trees (#241,303-311) were not originally requested by the client for reassessment and were not part of the original scope of work. DRG has since then assessed the remaining trees.
Photo documentation of the new trees are included with this letter. The client or the City of Cupertino may request additional photos.
Any work performed within the tree protection zone, such as trenching, should be monitored by an ISA Certified Arborist.
Please feel free to contact me if you would like more information or have any questions.
Sincerely,
Sabrina Huey

In May 2026, Davey Resource Group (DRG) was contacted by Joshua Vrotsos of Divided Homes to conduct a site verification of the existing tree inventory made by Ray Morneau dated August 2025 and updated March 2026. DRG assessed and developed a tree protection plan for specific trees identified by the client and the City of Cupertino as related to the alternative proposed development at 1655 De Anza Blvd. in Cupertino, CA.
On June 4, 2026, an International Society of Arboriculture (ISA) Certified Arborist (Sabrina Huey, #WE-14060A) from Davey Resource Group conducted the evaluation of five (5) new trees were assessed and sixty four (64) trees were re-assessed. On August 5, 2026 ten (10) remaining trees were re-assessed for a total of seventy nine (79) trees. Trees on and off the property that may be impacted by the project were assessed. Current plans and previous arborist reports reference the removal of trees located on 1601 S De Anza Blvd due to a separate project. The City of Cupertino requested tree protection measures for the trees to be retained, and the assessment of missing trees from the first assessment. The tree protection measures requested by the City are outlined in this report.
This report focuses on tree protection recommendations for tree preservation to help guide work around them and to reduce potential impacts on the trees. The trees identified for preservation should be monitored by a Certified Arborist at the end of construction and ongoing as needed.
Introduction
Assignment
The arborist visually assessed the specified trees on the site expected to be impacted, the environment beneath the driplines, and site conditions. Following data collection, specific tree preservation plans were determined to better ensure survivability during the planned project. This report establishes the condition of the trees and their canopies within the project area. The arborist visually assessed each tree on the site, and the required tree attributes were collected. Following data collection, specific tree preservation plan elements were calculated that identified each tree's critical and structural root zones (CRZ and SRZ) to better ensure survivability during the planned development. The trees were also photo documented so that any change in condition can be evaluated if needed.
Limits of the Assignment
Many factors can limit specific and accurate data when performing evaluations of trees, their conditions, and potential for failure or response to site disturbances. No soil or tissue testing was performed. All observations were made from the ground on June 4, 2026 and August 5, 2026. The determinations and recommendations presented here are based on current data and conditions that existed at the time of the evaluation and cannot be a predictor of the ultimate outcome for the evaluated trees in the future. No physical inspection of the upper canopy, sounding, resistance drilling, soil excavation to expose roots, or other technologies were used in the evaluation of the trees. Only trees specified by the client were observed. Plans dated 8-4-2026, titled T-1.0 were used as reference for arborist recommendations.
Observations
Methods
Data was collected by an International Society of Arboriculture (ISA) Certified Arborist (WE-14060A) on June 4, 2026 and on August 5, 2026. The results were used to determine the Tree Protection Zone (TPZ) and any other tree protection measures required during construction. The location and dripline of all trees four inches or greater in diameter at standard height (DSH, 4.5 ft. above grade) were documented. 1655 De Anza Blvd., Cupertino 2 June 2026 - Updated Aug 2026 A visual inspection was used to develop the findings, conclusions, and recommendations found in this report. Data collection included measuring the diameter of significant trees at approximately 54 inches above grade (DBH), height estimation (+/- 5ft), average dripline distance, a visual assessment of tree condition, structure, and health, and a photographic record. A rating percentage (0-100%) was assigned for each tree’s health, structure, and form, and the lowest percentage was used as the overall tree condition. Using the lowest of the above factors together with the arborist’s best judgment, the general condition of each tree was recorded in one of the following categories, adapted from the rating system established by the International Society of Arboriculture and the 10th Edition of the Council of Tree & Landscape Appraisers (CTLA) Guide for Plant Appraisal 1 Condition: Condition ratings were based on but not limited to (1) the condition and environment of the tree’s root crown; (2) the condition of the trunk, including decay, injury, callusing, or presence of fungus sporophore; (3) the condition of the limbs, including the strength of crotches, amount of deadwood, hollow areas, and whether they bore excessive weight; (4) the condition and growth rate history of the twigs, including pest damage and diseases; (5) the leaf appearance, including abnormal size and density as well as pest and disease damage.
Using an average of the above factors together with the arborist’s best judgment, the general condition of each tree was recorded in one of the following categories, adapted from the rating system established by the International Society of Arboriculture and the 10th Edition of the Council of Tree & Landscape Appraisers (CTLA) Guide for Plant Appraisal
1 :
● Excellent: High vigor and near-perfect health with little or no twig dieback, discoloration, or defoliation. It is nearly ideal and free of structural defects. It is a nearly ideal form for the species and is generally symmetrical. ● Good: Vigor is typical for the species and has no significant damage due to disease or pests. Twig dieback, discoloration, or defoliation is minor. Well-developed structure with minor defects that can be corrected easily. Minor asymmetries/deviations from species norm. Function and aesthetics are not compromised. ● Fair: Reduced vigor. Damage due to insects or diseases may be significant and associated with defoliation, but is not likely to be fatal. Twig dieback, defoliation, discoloration, and/or dead branches may comprise up to 50% of the canopy, a single structural defect of a significant nature or multiple moderate defects; structural defects are impractical to correct or require multiple treatments over several years, or major asymmetries/deviations from species norm. Function and aesthetics are compromised. ● Poor: Unhealthy and declining in appearance. Poor vigor, low foliage density, and poor foliage color are present. Potentially fatal pest infestation. Extensive twig or branch dieback. A single serious structural defect or multiple significant defects. Observed structural problems cannot be corrected. The tree is often a largely asymmetrical or abnormal form. The form detracts from the aesthetics or intended use to a significant degree.
● Very Poor: Poor vigor and appears to be dying. Little live foliage. Single or multiple severe structural defects. It is visually unappealing and offers little to no functionality in the landscape. ● Dead
Analysis & Recommendations
The City of Cupertino requested alternative plans to retain the trees along 1601 S De Anza Blvd., Cupertino. The City of Cupertino also requested some additional information on some trees that were missing on the previous arborist report.
While the majority of the trees do not fall under the specimen tree species list, the client will want to follow up with the City of Cupertino to determine if the trees were part of the required trees requirements. Unless otherwise noted below, all retained trees shall be protected in accordance with the General Tree Protection Measures provided in the following section. The City of Cupertino defines the Tree Protection Zone (TPZ) as the dripline of the tree, and must follow the requirements, unless approved otherwise.

1655 De Anza Blvd., Cupertino 3 June 2026 - Updated Aug 2026 Trees #303-311 and 241 are all trees in the footprint of the proposed buildings, landscape, road and driveway. Removal of the trees is required under these plans. The client should follow up with the City of Cupertino to see if trees #303-311 are part of a required tree development. If the trees are part of a required tree program a permit is required for the removal of the trees. Tree #241 is a city owned tree and a permit is required for the removal of the tree.
Should the neighboring property owners retain trees #242-249, and 1 all on the neighboring property of 1601 S De Anza Blvd. The new proposed work is about 10 ft away from the retaining wall. There is a storm drain and walkway within 5 ft of the property line, but is further away than the proposed retaining wall. The drain is about 15-20 ft away from the closest tree. The storm drain work will occur outside of the structural root zone. Due to the size of the trees the impacts of the combined work is expected to be moderate. The proposed work of the retaining wall will encroach within 5-6 ft of the structural root zone of trees #242 and 244. This will affect about 10-15% of the structural root zone.
The trees are likely to survive the proposed work, following the following arborist recommendations. There is an existing wall that separates the property from the trees. Should the trees be retained then tree protection fencing should be installed along the existing wall along the edge of the canopy. The fencing should temporarily be removed when the existing hardscape is removed. Once the fencing is back in place, any excavation or grading that occurs within the TPZ should be done under arborist supervision. Any roots 2-inches or greater in diameter should only be removed with the approval of the onsite arborist. The trees have been continuously pruned for the existing wall clearance, and is not likely to need any additional canopy clearances for the proposed work. The client should take extra care to protect this tree and make any additional changes needed to retain the tree due to the size of the trees and the trees belonging to a neighboring property.
Should the neighboring property owners retain trees. Trees #250-251 are along the proposed driveway in the neighboring property. The trees are expected to have high impacts from the proposed work, and the client may want to consider possible removal of the trees. A permit and approval from the property owners is required for the removal of the trees. If the client were to update the plans to reduce impacts to these two trees, the fencing recommendations would be to have the fencing installed along the existing wall along the edge of the canopy. The fencing should temporarily be removed when the existing hardscape is removed. Once the fencing is back in place, any excavation or grading that occurs within the TPZ should be done under arborist supervision. Any roots 2-inches or greater in diameter should only be removed with the approval of the onsite arborist. The plans do not indicate any buildings being built near by these trees, but the trees could use a trim to raise the canopy for vehicle clearances. Tree #251 is completely clear and will not require much of a canopy clearance. Tree #250 has a relatively low canopy, but currently meets vehicle clearances. It is likely that the tree would require some additional clearances and would prune about 30% of the canopy which is greater than the industry standard and in the City of Cupertino considered excessive pruning. This tree is in fair condition as well as being on the neighboring property. If the property owners elect to retain the trees, pruning should initially be limited to the minimum necessary for clearance and should be monitored by an on-site arborist. After a twelve-month period, additional clearance pruning may be considered if Tree #250 remains in fair or better condition. The client should take extra care to protect this tree and make any additional changes needed to retain the tree due to the size of the trees and the trees belonging to a neighboring property.
Trees #313-314, and 2 are all neighboring trees that are located in planting strips. The tree protection fencing should be installed along the edge of the planting strip. The impacts are expected to be low to moderate. Although work may occur within the SRZ of the trees to be retained, it is estimated to occur outside of the planting strip. The trees are likely to survive the proposed work, following the following arborist recommendations. If the planter is replaced, then an excavation or grading that occurs should be done under arborist supervision. The proposed sound wall should be installed with a pier and beam to reduce root pruning impacts. During the installation of the footing, the project arborist should monitor the work. The impacts of the footing and the replaced planting strip should be low due to the size of the trees and the previous locations that the trees are planted in. Any excavation or grading that occurs within the TPZ should be done under arborist supervision. Any roots 2-inches or greater in diameter should only be removed 1655 De Anza Blvd., Cupertino 4 June 2026 - Updated Aug 2026 with the approval of the onsite arborist. The client should take extra care to protect this tree and make any additional changes needed to retain the tree due to the tree belonging to a neighboring property.
Tree #312 is a large redwood tree. The fencing should be installed along the dripline of the tree. Impacts are expected to be moderate due to the amount of work occurring with the SRZ of the tree. The tree is likely to survive the proposed work, following the following arborist recommendations. The fencing should temporarily be removed when the existing hardscape is removed with onsite arborist supervision. Once the work is completed, the fencing should be installed back along the dripline of the tree. Once the fencing is back in place, any excavation or grading that occurs within the TPZ should be done under arborist supervision. Any roots 2-inches or greater in diameter should only be removed with the approval of the onsite arborist. The proposed sound wall should be installed with a pier and beam to reduce root pruning impacts. During the installation of the footing, the project arborist should monitor the work, the project should allow the arborist to approve or deny the pruning of large roots in order to retain this tree, this will ensure that less than 25% of the roots are impacted by the proposed project.
Trees 301-302 are trees that are recommended for removal due to conflicts with the sound wall. The client should follow up with the City of Cupertino to see if the trees are part of a required tree development. If the tree is part of a required tree program a permit is required for the removal of the trees.
Trees #297-300 all line the property and are all to be retained. While work is occurring within the CRZ of the trees to be retained, the impacts due to the pier and beam work are expected to be low to moderate. The trees are likely to survive the proposed work, following the following arborist recommendations. The tree protection fencing will be installed outside of the dripline of the trees. The impacts are expected to be low to moderate since work may occur within the SRZ of the trees to be retained. The fencing should temporarily be removed when the existing hardscape is removed with onsite arborist supervision. Once the work is completed, the fencing should be installed back along the dripline of the tree. The proposed sound wall should be installed with a pier and beam to reduce root pruning impacts.
During the installation of the footing, the project arborist should monitor the work. Any excavation or grading that occurs within the TPZ should be done under arborist supervision. Any roots 2-inches or greater in diameter should only be removed with the approval of the onsite arborist.
Trees #252-261, and 2 are all neighboring trees that are in an elevated wall along the edge of the property. The impacts are expected to be low to moderate since work may occur within the SRZ of the trees to be retained. The trees are likely to survive the proposed work, following the following arborist recommendations. The fencing should temporarily be removed when the existing hardscape is removed with onsite arborist supervision. Once the work is completed, the fencing should be installed back along the dripline of the tree. Once the fencing is back in place, any excavation or grading that occurs within the TPZ should be done under arborist supervision. Any roots 2-inches or greater in diameter should only be removed with the approval of the onsite arborist.
Trees #262-292 are all trees located along the edge of the parking lot. The trees are all expected to have low to moderate impacts due to work occurring with the SRZ of the trees to be retained. The trees are likely to survive the proposed work, following the following arborist recommendations. The fencing should temporarily be removed when the existing hardscape is removed with onsite arborist supervision. Once the work is completed, the fencing should be installed back along the dripline of the tree. The proposed sound wall should be installed with a pier and beam to reduce root pruning impacts. During the installation of the footing, the project arborist should monitor the work. Any excavation or grading that occurs within the TPZ should be done under arborist supervision. Any roots 2-inches or greater in diameter should only be removed with the approval of the onsite arborist.
Tree #3 is a neighboring tree that is expected to have none to low impacts. The tree is likely to survive the proposed work, following the following arborist recommendations. The tree will be protected due to the fencing around the surrounding trees, no additional tree protection fencing needs to be installed. 1655 De Anza Blvd., Cupertino 5 June 2026 - Updated Aug 2026 Tree #4 is a neighboring tree that is 8 ft away from the property line. The proposed work is about 6 ft away from the tree. The work impacts are expected to be moderate since work is proposed within the SRZ of the tree to be retained.
The tree is likely to survive the proposed work, following the following arborist recommendations. The tree protection fencing should be installed along the edge of the property line. Any excavation or grading that occurs within the TPZ should be done under arborist supervision. Any roots 2-inches or greater in diameter should only be removed with the approval of the onsite arborist. The client should take extra care to protect this tree and make any additional changes needed to retain the tree due to the size of the tree and the tree belonging to a neighboring property.
Trees 293-296 are to be removed due to the condition of the trees and the trees being in the footprint of the proposed work. The client will want to follow up with the City of Cupertino to see if the trees are part of a required tree development. If the tree is part of a required tree program a permit is required for the removal of the trees.
In addition to site specific recommendations above, the following sections identify general best practice recommendations for tree preservation.
● Install Tree Protection Zone (TPZ) fencing at the calculated TPZ listed in Table 2 below and the report written by Ray Morneau, at the pavement edge, or designated Limit of Disturbance (LOD) of the trees to be retained and remain in place for the entirety of the project. Access into the TPZ should not be allowed unless determined to be necessary and only under the supervision of a certified arborist. The tree protection area may be reduced by following tree protection measures. The fence shall be a minimum of five feet in height and shall be set securely in place. The fence shall be of a sturdy but open material (i.e., chain link), to allow visibility to the trunk for inspections and safety. The fence shall be in place until construction has been completed. There shall be no storage of any kind within the protective fencing. TPZs shall be constructed in such a fashion as to not be easily moved or dismantled. ● As the proposed additions are within the TPZ’s, the fencing may be moved in as needed but should be returned to the TPZ edge as soon as possible. The tree protection area may be reduced by following tree protection measures.
● “Tree Protection Area - Keep Out” or similar signs shall accompany the TPZ fencing every 15 feet and include contact information to report violations.
● Access into the TPZ should not be allowed unless determined to be necessary and only under the supervision of a certified arborist.
● Any excavation within the TPZ’s must be hand-dug, or done with pneumatic air spade or hydro-vac, and should be monitored by a Certified Arborist. All impacts shall be documented. ● Any roots >2-inch diameter may only be pruned with approval from the on-site arborist. ● All heavy equipment must remain outside of the TPZ. No stockpiling of materials, vehicular traffic, or storage of equipment or machinery shall be allowed inside the TPZ. ● All pruning shall be done by a Certified Arborist or Certified Tree Worker in accordance with the Best Management Practices for Pruning (International Society of Arboriculture, 2002) and adhere to the most recent editions of the American National Standard for Tree Care Operations (Z133.1 and Pruning (A300). ● TPZs shall remain in place for the entirety of the project and only removed, temporarily or otherwise, by an ISA Certified Arborist after submission and approval of intent. ● Trees should be irrigated regularly.
● If the soil within the TPZ is compacted, then aerate the soil using an air spade to alleviate compaction and promote the flow of oxygen and water to the roots.
● Add a 3-inch layer of mulch to the portion of the root zone protected by the TPZ. Be sure not to cover/bury the tree root collar. Mulch aids the soil in water retention and also helps insulate the soil from hot and cold weather extremes.
1655 De Anza Blvd., Cupertino 6 June 2026 - Updated Aug 2026 ● Where possible, add a 4-6-inch layer of wood chips over any parts of a root zone not protected by the TPZ.
This aids in reducing the impact of soil compaction from foot traffic and/or heavy equipment during the upcoming construction activities.
