1.0 INTRODUCTION
The City of Cupertino Community Development Department has retained me to prepare
this Arborist Report in connection with the proposed application to construct a five -story,
148 -room hotel named Hyatt House Hotel at Vallco Park; the property is a triangular-
shaped lot, bordered by Interstate 280 to the north, N. Wolfe Road to the west, and
Perimeter Road to the south (APN 316-20-092), and currently serves as an overflow
parking lot for Vallco Mall.
Specific tasks assigned to perform are as follows:
■ Visit the site on May 12 and 15, 2014 to identify 150 trees having trunks with
diameters of four inches and greater (measured 54 inches above grade).
■ Determine each tree's trunk diameter at 54 inches above grade or where appropriate
to obtain the best representation of trunk size. Diameters are rounded to the nearest
inch, and trees listed with more than one diameter are formed by multiple trunks.
■ Ascertain each tree's health and structural integrity, and assign an overall condition
rating (e.g. good, fair, poor or dead).
■ Determine each tree's suitability for preservation (e.g. high, moderate or low).
■ Obtain photographs; see Exhibit C.
■ Identify which trees have trunks situated within the public right-of-way.
■ Assign tree numbers in a sequential pattern, and those locations can and numbers can
be viewed on Sheet A-0.2 presented in Exhibit B (copy of the Demolition/Tree
Removal Plan, dated 7/15/14).
■ Affix metal tags with engraved, corresponding numbers to each accessible trunk or
major limb (the tags are round aluminum).
■ Review the plan set dated 7/15/14 to identify potential tree disposition and impacts.
■ Provide tree replacement guidelines.
■ Develop general protection measures to help avoid or mitigate impacts to trees
planned for retention.
■ Prepare a written report that presents the aforementioned information, and submit via
email as a PDF document.

2.0 TREE COUNT AND COMPOSITION
One -hundred fifty (150) trees of eight various species were inventoried for this report.
They are sequentially numbered as 1 thru 150, and the table below, and continued on the
following two pages, identifies their common names, assigned numbers, counts and overall
percentages.

As illustrated above, the site is populated predominantly by coast redwoods, which form a
highly dense and established screen along the north (Hwy 280) and west (N. Wolfe Road)
boundaries. The redwoods exhibit symptoms of significant or severe stress from not
receiving sufficient water over the years, and the vast majority appear in poor health. Of
these, many are beyond recovery, and others might improve if an assertive watering
program is immediately implemented. Absent of supplemental water, continued decline
for many years later can be expected, and those otherwise intended for retention and
protection may ultimately require removal.

Specific information regarding each tree is presented within the table in Exhibit A. The
trees' locations and corresponding numbers can be viewed on the site map in Exhibit B,
and photographs are presented in Exhibit C.
One tree, #96, is a within the public right-of-way along N. Wolfe Road and defined as a
street tree.
Sheet A-0.2 identifies two 'trees #102.' The one immediately north of #101 is the correct
one, and the other near #107 and 108 is small evergreen pear with a trunk diameter less
than three inches; see the map in Exhibit B for further clarification.
Four coast live oaks are defined as "specimen trees" pursuant to Appendix B of Ordinance
No. 07-2003; they include #91, 92,145 and 146.
3.0 SUITABILITY FOR TREE PRESERVATION
Each tree has been assigned either a "high," "moderate" or "low" suitability for
preservation rating as a means to cumulatively measure and consider their existing health,
structural integrity, anticipated life span, available growing space, location, size and
species. A description of these ratings are presented below; note that the "high" category
comprises nine (or 6%), the "moderate" category 58 (or 39%), and the "low" category 83
(or 55%) of the total inventoried trees.
High: Applies to trees #14, 20, 29, 32, 33, 44, 89, 95 and 97.
These trees offer a good potential for contributing long-term to the site; appear reasonably
healthy with stable structures; have no apparent, significant health issues or structural
defects; and require regular care to maintain their longevity and vigor.
Hyatt House Hotel at Vallco Park, Cupertino Page 3 of 16
City of Cupertino Community Development Department
David L. Babby, Registered Consulting Arborist° July 24, 2014
Moderate: Applies to trees #3, 5, 8, 10, 15, 16, 21-28, 30, 31, 35, 36, 39, 41, 42, 45-52,
54, 55, 57-59, 61, 63-65, 75, 82, 87, 91-93, 98-102, 107, 118, 119, 124, 125, 131, 132, 139
and 143.
These trees contribute to the site but at levels less than those assigned a high suitability;
have health and/or structural issues that can potentially be reasonably addressed and
property mitigated; and frequent care is typically required for their remaining lifespan. A
good number of redwoods within this rating serve as established screening elements
between Interstate 280 and N. Wolfe Road; they are assigned moderate suitability solely
for this reason, as well as the potential of health recovery, including numerous that have
been "topped" and/or suppressed growth due to adjacent, more established trees (they
would otherwise be assigned a low suitability for their poor health condition).
Low: Applies to trees #1, 2, 4, 6, 7, 9, 11-13, 17-19, 27, 34, 37, 38, 40, 43, 53, 56, 60, 62,
66-74, 76-81, 83-86, 88, 90, 94, 96, 103-106, 108-117, 120-123, 126-130, 133-138, 140-
142 and 144-150.
These trees are either dead, nearly dead, severely declined, highly suppressed in terms of
canopy and trunk development, and/or have such serious structural defects that they are
expected to worsen regardless of tree care measures employed (i.e. beyond recovery).
None appear suitable for retention.
Of low suitability trees, the following four should be immediately removed: #94, 123,
126 and 145. Trees #94, 123 and 126 are dead. Tree #145 has a massive split where four
leaders originate, and is at severe risk of breaking at any time (presents an immediate,
hazardous risk to persons and vehicles below).

4.1 Proposed Removals
The following 114 trees are identified for removal to accommodate the proposed project
design and/or low suitability for preservation: #1, 2, 4, 6, 7, 9, 11-13, 17-19, 27, 34, 37, 38,
40, 43, 53 and 56-150.
The above list considers the following:
■ All redwood trees along the western boundary for construction of the proposed path
(the vast majority are in poor condition).
■ All trees at the southwest section of the site to accommodate the proposed path,
driveway, and grading.
■ All trees within the existing parking lot to allow building construction.
■ All trees within the planter strip along Perimeter Road for site improvements.
■ Select redwoods along the north boundary due to being in poor condition.
■ Trees at the northwest corner of the property for the bioretention planter.
Of the 114 trees, three are assigned a high suitability, 27 a moderate suitability, and 84 a
low suitability; none are suitable for relocation. The high suitability trees include #89, 95
and 97, all sizeable coast redwoods with trunk diameters of 30, 22 and 24 inches,
respectively, but appear in only fair health condition; their removal appears necessitated by
the proposed path, driveway, and associated grading at the southwest corner of the site.
Sheet A-0.2 provides information regarding the proposed tree disposition. Several
observations and recommendations for updating that plan are as follows:
■ The elevations shown for trees differs from those provided on the civil drawings.
As such, the plan needs to be substituted with the Sandis topo for a base map,
assuming the Sandis topo reflects the correct elevation and site information.
■ Trees #57, 58 and 59 need to reflect removal due to being within the proposed
bioretention planter and immediately adjacent to the storm drain.
■ Omit the additional #102 discussed in Section 2.0 of this report (page 3).

4.2 Potential Significant Impacts
Of the 36 trees planned for retention, implementation of the proposed design would
subject a number to a high or severe level of impacts. Discussion and recommendations
for design modification to achieve adequate protection are provided in this section.
Redwood trees #14, 15, 16, 20 and 21 will sustain potentially severe root loss during
excavation for the new section of parking lot at the northeast section of the property. To
achieve protection, the section of existing planter within at least 12 feet from their
trunks should remain intact and be regarded as their Tree Protection Zone ("TPZ"
hereinafter).
The proposed relocation of the cellular equipment enclosure will result in excavation
within a significant section of tree #10's root zone, and the process may expose root
damage or loss to #14-16, 20 and 21. I recommend a plan for relocating this feature is
provided to best assess impacts.
For trees retained along the northern border, excavation for the proposed storm drain and
inlets would expose the redwood to the potential loss and/or damage to large roots within
the parking lot. To reduce the risk of damage or impacts, I recommend the main line is
established at least ten feet from the trunks. The inlets can be placed at the edge of
proposed lot, however, must be strategically located away from retained trees (i.e. in voids
containing trees that are either small or proposed for removal), and the lines connecting the
inlets to the storm in a radial direction to tree trunks. A possible alternative is for the line
to be directionally -bored by 36 inches or more below grade, and the access pits established
beyond the canopy of a retained tree.
The proposed nine light poles along the north boundary show footings within the existing
planter and immediately adjacent to the following 12 trees: #16, 21, 26, 30, 31, 35, 36, 41,
441 45, 49 and 54. To avoid potentially significant impacts, I recommend the light poles
are situated or designed so that no drilling or excavation is needed within the planter (a
Hyatt House Hotel at Vallco Park, Cupertino Page 6 of 16
City of Cupertino Community Development Department
David L. Babby, Registered Consulting Arborist° July 24, 2014
possible alternative is to place them within the finger islands). The electrical layout should
also be configured as described above for the storm drains.
Another potential impact for trees along the north boundary involves the footing design
and installation method of the proposed wall/curb. It is critical that the future curb and
gutter do not require lateral excavation into the existing planter (i.e. any soil and roots
behind existing back of curb), including for overexcavation to construct, form and pour the
wall/curb, footing and gutter. Additionally, the wall/curb and gutter should not require
excavation into existing base material, or have the flexibility for as -built changes, should
roots of two inches and greater in diameter be encountered. Additionally, existing base
material should be utilized for the new lot where roots of this size become encountered.
The electrical layout for lighting or purposes becomes a critical component to avoid
trenching within protection zones, and subsequently, can result in severe root loss. To
avoid this from occurring, I recommend the layout is established, reviewed and approved
prior to building permit issuance, and the routes established beyond tree protection zones.
The path proposed along the north side of the northern shared fence line appears to
present no significant impacts to adjacent redwoods, provided excavation is not needed for
its construction (i.e. a no -dig design, including for base materials, forms and edging), and
direct compaction of existing soil grade can be avoided grade. A material that may achieve
these specifications is Tensar Biaxial Geogrid (www. tensarcorp. com).
Note that for any trees redwoods being considered for retention, it is critical to begin
immediately supplying them with supplemental water. Their current, overall poor and
dying condition can be attributed to an absence of water.

Applying Section 14.18.185, Table A, of the City Code, one of the following options
would be applied for mitigating removal of the 114 trees:
■ Installing 187 trees of 24 -inch box size.
■ Installing 109 trees of 24 -inch box size plus 39 of 36 -inch box size.
■ Installing 109 trees of 24 -inch box size, and for the additional 78 trees of 24 -inch
box size, any combination of one 36 -inch box for every two 24 -inch boxes.
Based on the table presented on L-3, a total of 95 trees of 24 -inch box size are proposed
for installation, a difference of 92 trees of 24 -inch box trees to meet Code Section
14.18.185 for mitigation replacements.
My review of the landscape plans reveals several opportunities to enhance replacement
mitigation, namely the following:
■ As many trees as necessary along the front of the building could be upsized to 36 -
inch boxes.
■ Trees could be installed within the bioretention planter, such as Marina madrone,
Fernleaf Fullmoon maple, or Elegant Brisbane box.
■ Trees could be installed within the barren area at the southwest corner of the
property.
■ Once Sheet L-3 is coordinated with all removals shown on A-0.2, such as along the
north property edge, additional space and opportunity will be created for installing
new trees.
Regarding the species proposed for replacements, I recommend the following:
■ For the London planes, substituting 'Bloodgood' with the 'Columbia.'
■ Substituting Shamel ash with one of the following: Shumard red oak or Autumn
purple white ash. The Shumard is preferred, but due to the multi -leader, competing
structure, it is important to select ones with a dominant central leader.
■ Consider additional species, such as mentioned for the bioretention planter, and
possibly a valley oak or cork oak in a larger planter area.

Regarding redwoods to be installed along the west boundary, the existing coast redwoods
are roughly spaced, on average, nine to ten feet apart. I suggest 12 feet between each tree
would provide appropriate spacing for this site.
For redwoods to be installed along the north boundary, there are some instances where
redwoods are proposed for removal due to being under highly suppressed and crowded -
growing conditions, and installing a new redwood would be futile due to inadequate space,
sunlight, and the established dominance of adjacent redwoods with broad canopies. There
are other instances where trees are proposed for removal due to being in poor condition,
but there appears sufficient sunlight and spacing for new redwoods, if not one to each
removed tree, then one between where two are removed. Suggestions and considerations
for the locations and amounts of replacements are as follows:
■ The area occupied by #9, 27, 34, 40, 43 and 56 should not be replaced.
■ Replacements for #1, 2, 4, 11, 12, 13, 53 and 60-63 should be installed within the
same trunk areas as of the removed trees.
■ One tree is suggested between #17 and 18, and another between #37 and 38.
■ The spacing distance between new and existing would vary along the north
boundary to accommodate the above recommendations and consider existing
conditions, such as the dominance of existing redwoods crowding out available
planting space and sunlight.
■ For new redwoods installed, I do not anticipate those planted in close proximity of
established ones will sustain sufficient growing space and sunlight to reach a
similar height. Those setback some from established ones do present a reasonably
good opportunity though, and estimate that under favorable growing conditions, 15
to 20 years may allow them to reach a similar height.
Based on the amount of new trees to be installed, they should be selected and tagged at
the nursery by an ISA (International Society of Arboriculture) certified arborist and/or the
landscape architect prior to being shipped to the site. They should have relatively
symmetrical structures mostly free of obvious defects, wounds and girdling roots.
Hyatt House Hotel at Vallco Park, Cupertino Page 9 of 16
City of Cupertino Community Development Department
David L. Babby, Registered Consulting Arborist° July 24, 2014
Additionally, the arborist and/or landscape architect should be retained to examine and root
prune, as needed, once the boxes are removed and before being installed.
All new trees should be installed, including necessary irrigation, by an experienced state -
licensed landscape contractor or a professional tree service company, and performed to
professional industry standards. Only if necessary to stand upright, they should be double -
staked (no cross -brace) with rubber tree ties or equivalent, and the support stakes cut below
the first main lateral branch. Percolation tests should also be performed for each planting
pit to ensure drainage is achieved.
All irrigation should be supplied through valves and automatic timers separate from that
of shrubs, plants and groundcover, and supplied by two bubblers placed and staked on the
surface of the root ball (versus against the trunk or in a sleeve) at around the one-half or
three-quarters of the distance between the trunk and rootball edges. Additionally, an eight -
inch tall circular berm formed by soil should be formed around the perimeter of the
rootball (for water from the bubblers to flood). A two- to three-inch layer of wood -chip
mulch should be spread on top and 12 inches beyond the root ball (but not piled against the
trunks).

Recommendations presented within this section serve as general design guidelines to help
mitigate or avoid impacts to trees being retained. They are subject to revision upon
reviewing the updated project design, and I should be consulted in the event any cannot be
feasibly implemented. Please note that all referenced distances from trunks are intended
to be from the closest edge (face of) of their outermost perimeter at soil grade.
6.1 Design Guidelines
1. All recommendations presented in Section 4.0 of this report should be considered
part of this section.
2. A TPZ is where all trenching, soil scraping, compaction, grading (cut and fill),
removal of underground utilities and vaults, finish -grading, overexcavation,
subexcavation, swales, bioswales, storm drains, equipment cleaning, stockpiling and
dumping of materials, and equipment/vehicle operation shall be avoided. For general
design purposes, the minimum TPZs of select trees that may potentially be retained
are provided in Section 4.0 of this report. For all other inventoried trees not
mentioned in Section 4.0 but being retained, I recommend their TPZs are up to 12
inches from proposed improvements, and beneath their entire canopies in all other
directions. Where an impact encroaches slightly within a setback, it can be reviewed
on a case-by-case basis to determine appropriate mitigation measures.
3. The tree numbers of all retained trees should be added to the civil and landscape
plans to allow for efficient design review for both the City and contractors.
4. Sheet C-3.0 should show the limits of grading.
5. All existing, unused lines, pipes and manholes within a TPZ should be abandoned
and cut off at existing soil grade (rather than being dug up and causing subsequent
root damage); this provision should be specified on A-0.2.
Hyatt House Hotel at Vallco Park, Cupertino Page 11 of 16
City of Cupertino Community Development Department
David L. Babby, Registered Consulting Arborist° July 24, 2014
6. Overexcavation for constructing any curb, gutter, walk, foundation etc. within a
TPZ should be reduced to the maximum extent possible, such as six inches.
7. Shoring should be specified for the north side of the proposed underground garage.
8. The permanent and temporary drainage design, including downspouts, should not
require water being discharged within TPZs. Also, any swales needed for drainage
within a TPZ should require no more than a three-inch soil cut and fill, and roots two
inches and greater in diameter retained and not damaged.
9. Any underground utilities and services (e.g. electrical) should be routed beyond
TPZs. Where this is not feasible, the section of line(s) within the TPZ should be
directionally -bored by at least four feet below existing grade, or installed by other
means (e.g. pipe -bursting) to avoid an open trench. The ground above any tunnel
must remain undisturbed, and access pits and any above -ground infrastructure (e.g.
splice boxes, meters and vaults) established beyond all TPZs.
10. The future staging area and route(s) of access should be shown on the final site plan
and avoided on unpaved areas beneath or near canopies. Where not feasible, I should
be consulted to review the location and proximity to particular trees, and strive to
identify a temporary root zone buffer that could potentially minimize soil compaction
within a TPZ, and in turn, lessen impacts to a tree's vigor and longevity.
11. To restrict spoils and runoff from traveling into root zones, the future erosion
control design should establish any silt fence and/or straw rolls away from a tree's
trunk (not against it), and as close to the canopy edge as possible. Additionally,
where within a TPZ, the material should require none or a maximum vertical soil cut
of two inches for its embedment.
12. The landscape design should conform to the following additional guidelines:
a. Large growing trees, such as those that can exceed the height of retained trees,
should be installed beyond TPZs, and at least 10 to 15 feet from a future
foundation, wall and hardscape.
Hyatt House Hotel at Vallco Park, Cupertino Page 12 of 16
City of Cupertino Community Development Department
David L. Babby, Registered Consulting Arborist° July 24, 2014
b. Plant material installed beneath canopies of oaks must be drought -tolerant,
limited in amount, and planted at least five or more feet from their trunks. Plant
material installed beneath the canopies of all other trees should be at least 36
inches from their trunks.
c. Irrigation and lighting features (e.g. main line, lateral lines, valve boxes,
wiring and controllers) should be established so that no trenching occurs within
a TPZ. In the event this is not feasible, they may require being installed in a
radial direction to a tree's trunk, and terminate a specific distance from a trunk
(versus crossing past it).
d. Ground cover beneath canopies should be comprised of a three- to four -inch
layer of coarse wood chips or other high-quality mulch (gorilla hair, bark or
rock, stone, gravel, black plastic or other synthetic ground cover should be
avoided). Mulch should not be placed against the trees' trunks.
e. Tilling, ripping and compaction within TPZs should be avoided.
f. Bender board or other edging material proposed beneath the canopies should
be established on top of existing soil grade (such as by using vertical stakes).
g. Providing ongoing supplemental water during the dry months of the year
following the project would benefit the longevity of redwoods and, possibly
applied through bubblers strategically located throughout the root zones.
Additional discussion can be provided upon request.
h. Ensure no recycled water is supplied to the redwoods.
6.2 Before Demolition, Grading and Construction
13. A site meeting with the general contractor and me ("project arborist" hereinafter)
should be conducted several weeks prior to work commencing for the purpose of
reviewing tree fencing locations and other measures presented in this report.
Additional site visits include reviewing root pruning and tree impacts during
construction, and providing a final assessment of project impacts (for scheduling
purposes, I request a minimum five business -day notice for these subsequent visits).
14. Tree protective fencing is needed prior to any grading, trenching or excavation for
the purpose of restricting access into and enclosing the entire TPZs. Its location can
be identified during the initial site meeting, and should remain intact and be
Hyatt House Hotel at Vallco Park, Cupertino Page 13 of 16
City of Cupertino Community Development Department
David L. Babby, Registered Consulting Arborist° July 24, 2014
maintained throughout construction. One approach is to utilize five-foot tall chain
link panels mounted on steel posts or concrete blocks, and the panels firmly
established to avoid easily being shifted or opened. Another includes mounting five -
to six-foot tall chain link on two-inch diameter steel posts that are driven into the
ground 24 inches deep.
15. The limits of sidewalk, streetscape and grading should be staked prior to any
digging occurring.
16. Wood chips may need to be spread on exposed ground beneath the canopies of select
trees. They should be coarse (e.g. 1/4- to 3/4 -inch in size), and spread to a four- to five -
inch layer beyond improvements, not piled against a trunk, and remain throughout
construction.
6.3 During Demolition, Grading and Construction
17. Great care must be taken during demolition of all existing features, to including the
existing structures, curbs, gutter, etc. to avoid excavating into the ground and
disturbing roots.
18. Any approved digging or trenching within a TPZ should be manually performed
without heavy equipment or tractors, including small ones, operating within a TPZ.
19. Any roots encountered during the process with diameters less than two inches in
diameter can be cleanly severed at a 90 -degree angle to the direction of root growth.
In doing so, sharp cutting tools (e.g. loppers or handsaw) shall be used, and the cut
should occur against the tree side of the trench. Roots considered for removal with
diameters of two inches and greater must first be reviewed by the project arborist.
20. Spoils created during digging must not be piled or spread within a TPZ. If necessary,
they can be temporarily piled on plywood or a tarp.
21. Tree trunks shall not be used as winch supports for moving or lifting heavy loads.

David L. Babby, Registered Consulting Arborist° July 24, 2014
22. Supplemental water is essential to promote, and in many instances improve, the
vigor and longevity of trees being retained, as well as help offset impacts. The
methodology, amount and frequency can be discussed prior to construction.
23. The disposal of harmful products (such as cement, paint, chemicals, oil and gasoline)
is prohibited beneath canopies or anywhere on site that allows drainage beneath or
near TPZs. Herbicides should not be used with a TPZ; where used on site, they
should be labeled for safe use near trees.
24. Any tree pruning should be performed by a California state -licensed tree service
company (D-49 classification) that has an ISA certified arborist in a supervisory role,
carries General Liability and Worker's Compensation insurance, and abides by in
accordance with ANSI A300-2001 (Pruning) and ANSI Z133.1-2006 (Safety
Operations) standards.
