1.0 INTRODUCTION
DES Architects + Engineers has retained me to prepaxe this Tree Survey Report in
connection with developing a new office building and a separate parking garage at 555 and
577 Airport Boulevard, Burlingame. The project is titled Burlingame Bay, and specific
tasks assigned to execute are as follows:
■ Identify 303 trees with trunk situated within the project site; site visits were
performed on 1/10/20, 1/13/20, 1/14/20 and 1/20/20.
■ Determine each tree's trunk diameter at 54 inches above grade, rounded to the
nearest inch. Trees with more than one diameter listed are formed by multiple trunks
or leaders.
■ Identify which are defined by Burlingame City Code as protected trees.l
■ Ascertain each tree's health and structural integrity, and assign an overall condition
rating (e.g. good, fair, poor or dead).
■ Rate each tree's suitability for preservation (e.g. high, moderate or low).
■ Document pertinent and observed health, structural and adjacent hardscape issues.
■ Assign numbers to the trees, and show each individual or group location on the aerial
map in Exhibit B(derived from Google Earth, image date 8/9/18).
■ Nail round metal tags with corresponding engraved numbers onto accessible trees
(includes all but #234, 235, 245-247 and 249).
■ Provide general design guidelines and protection measures to help avoid or mitigate
impacts to retained trees.
■ Prepare a written report that presents the aforementioned information, and submit via
email as a PDF document.
1 Secrion 11.06.020(fl(1) of the Burlingame City Code defines a protected tree, as it relates to this site, as
any species which has a trunk diameter of >15.28 inches measured 54 inches above natural grade.

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 its existing health; structural
integrity; anticipated life span; remaining life expectancy; prognosis; location; size;
particular species; tolerance to construction impacts; growing space; and safety to properry
and persons within striking distance. Descriptions of these ratings are presented below; the
� high category being comprised of no trees (0%), the moderate category 162 (or 53%), and
the low category 141 (or 47%).
Hi�h: Applies to none.
These trees appear relatively healthy and structurally stable; have no apparent, significant
health issues or structural defects; present a high potential for contributing long-term to the
site; and seemingly require only periodic or regular care and monitoring to maintain their
longevity and structural integrity.
Moderate: Applies to #11, 12, 14, 16, 19, 29, 30, 32, 34, 35, 39-49, 64-67, 69, 72, 73, 75,
76, 83-85, 100, 104, 111, 113, 115, 117, 122, 125-127, 130, 138, 145-148, 152, 154-176,
178-200, 204, 205, 211-224, 226, 228, 229, 231, 232, 235, 242-246, 248, 249, 251-259,
261-263, 265, 267-273, 275, 278, 280-286, 288-293, 295, 294 and 301.
These trees contribute to the site, but at levels less than those assigned a high suitability;
might have health and/or structural issues which may or may not be reasonably addressed
and properly mitigated; and frequent care is typically required for their remaining lifespan.
Low: Applies to #1-10, 13, 15, 17, 18, 20-28, 31, 33, 36-38, 50-63, 68, 70, 71, 74, 77-82,
86-99, 101-103, 105-110, 112, 114, 116, 118-121, 123, 124, 128, 129, 131-137, 139-144,
149-151, 153, 177, 201-203, 206-210, 225, 227, 230, 233, 234, 236-241, 247, 250, 260,
264, 266, 274, 276, 277, 279, 287, 294, 296, 298-300, 302 and 303.
These trees have significant health and%or structural issues expected to worsen regardless
of tree care measures employed (i.e. beyond likely recovery). As a general guideline, they
are not suitable for incorporating into the future landscape, and any which are retained
require highly frequent monitoring and care throughout their remaining lifespans to
minimize risk to any persons or property within striking distance (current andlor future).
Note that #15, 17, 31, 140, 150, 233, 234 and 236 are dead or nearly dead.

4.0 TREE PROTECTION MEASURES
Recommendations presented within this section serve as measures to help mitigate or
avoid impacts to trees being retained, and should be carefully followed throughout the
entire demolition and construction process. They are subject to change upon reviewing
future project plans, and I(hereinafter, "project arborist") should be consulted in the event
any cannot be feasibly implemented.
4.1 Design Guidelines
1. A Tree Protection Zone (TPZ) is necessary to restrict or confine the following
activities to help achieve a reasonable assurance of a tree's vigor, longevity and
anchoring capacity: trenching, soil scraping, compaction, mass and finish-grading,
overexcavation, subexcavation, tilling, ripping, swales, bioswales, storm drains,
dissipaters, equipment cleaning, removal of underground utilities and vaults, altering
existing water/drainage flows, stockpiling and dumping of materials, and equipment
and vehicle operation. For general design purposes, the TPZ of a particular tree
should be a minimum distance from its trunk of 7 to 10 times its trunk diameter in all
directions away from existing foundations, tall retaining/planter walls, and streets
(strive towards 10 times the diameter, and/or, beyond the actual canopy); for trees
with multiple trunks, utilize the largest diameter. In the event an impact encroaches
slightly within a setback, it can be reviewed on a case-by-case basis by the project
arborist to deternune whether measures can sufficiently mitigate the impacts to less-
than-significant levels.
2. All site-related plans should contain notes referencing this report for tree protection
measures.
3. Abandon all existing, unused lines or pipes within a TPZ, and any above-ground
section should be cut off at existing soil grade (rather than being dug up and causing
subsequent root damage); this provision should be specified on the demolition plan.

DESArchitects + Engineers, Inc.

David L. Babby, Registered Consulting Arboris� January 25, 2020
4. Design and route future utilities, irrigation, storm drains, dissipaters, bioswales (or
other bioretention device/structure) and swales beyond TPZs. Dictated by the
proximity to tree trunks, an alternative installation method may be warranted, such as
hand-digging, a pneumatic air device (such as an Air-Spade�), or directional boring.
For directional-boring, the ground above any tunnel must remain undisturbed, and
access pits and any infrastructure (e.g. splice boxes, meters and vaults) established
beyond TPZs.
5. Where within 10 feet from TPZ, confine grading (cut and fill), overexcavation,
subexcavation, trenching, compaction, and other ground disturbance to within 12 to
24 inches from any foundation, footing, curb, gutter, pavement, drive or retaining wall.
6. Any wall constructed beneath a canopy for the purposes of retaining fill away from a
TPZ should be, preferably, established on top of existing soil grade with no footing
(e.g. drystack), or alternatively, using a pier and above-grade beam foundation, where
the piers are minimized in diameter, spaced as far apart as possible, and the beams or
spans between the piers established on top or above existing soil grade (i.e. a no-dig
design except vertically for the piers). The ground beneath the beams or wall must
not be compacted or dug.
7. Structures should consider avoiding the need to remove large limbs (e.g. >3" in
diameter) or sections of canopies contributing to a tree's overall form, including to
erect construction scaffolding or needing manlifts.
8. The future staging area and route(s) of access should be routed beyond canopies and
unpaved areas of TPZs.
9. Avoid specifying the use of herbicides use within a TPZ; where used on site, they
should be labeled for safe use near trees. Also avoid prescribing liming within 50
feet of a tree.
10. Erosion control should consider that any straw wattle or fiber rolls require no more
than a 2-inch deep, vertical soil cut for their embedment, and are established as close
to canopy edges as possible (and not against a tree's trunk).

DESArchitects + Engineers, Inc.
David L. Babby, Registered Consulting Arborist� January 25, 2020
11. 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 be at least 10 to 15 feet from a future
foundation, wall and haxdscape.
b. Plant material installed beneath tree canopies should be at least 24 to 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 consist of a 3-inch layer of coarse wood
chips or other high-quality mulch (avoid gorilla hair, rock, stone, gravel, black
plastic or other synthetic ground cover). Keep mulch off the trees' trunks.
e. New fence posts (posts) should be placed at least 5 feet from a tree's trunk
(depends on trunk size and growth pattern); the post layout should be guided by
where laxge roots are likely located, which can be predetermined using a bully
probe (or similar), and collaborating with the project arborist.
f. Tilling, ripping and compaction within TPZs should be avoided.
g. 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).
4.2 Before Demolition, Grading and Construction
12. Pruning for any retained tall or large tree is needed, and should only be performed in
accordance with the most recent ANSI A300 standards, and by a California licensed
and bonded tree-service contractor (D-49) which has an ISA certified arborist in a
supervisory role and carries General Liability and Worker's Compensation insurance.
Also, the rubber wire cable within #187's canopy should be removed.
13. Where feasible, manually spread a 4- to 5-inch layer of coarse wood chips, 1�4' tO 3�4-
inch in size, over exposed ground beneath canopies; the type and source of these
wood chips should be from a professional and licensed tree service, and absent of
Sudden Oak Death infection (or the possibility thereo�. The chips should not be
piled against the trunks, and any existing leaf litter should remain in place and the
chips spread on top.

Page 7 of I1
David L. Babby, Registered Consulting Arborist° January 25, 2020
14. Where within a TPZ, the removal of plant material and groundcover must be
manually performed versus using heavy equipment operating and traveling on
unpaved ground. Additionally, the removal of stumps shall only be performed using
a stump grinder (versus excavating into the ground and inadvertently damaging roots).
15. Begin applying supplemental irrigation during the dry months of the year (e.g. May
thru October), at a rate of approximately 10 gallons per inch of trunk diameter every
two to three weeks via flooding the inside of a 12-inch tall berm established around
the canopy perimeters (or as close to the perimeters as possible). Alternatives
include using soaker hoses or through deep-root injection. Note, ultirnately, the
methodology, amount and frequency of irrigation can be best outlined closer to
construction commencing, and any applicable dewatering may require a more
intensive supplemental watering program than otherwise needed.
16. Install tree protection fencing prior to demolition or other site work for the purpose of
restricting access into unpaved sections of ground within a TPZ. Fencing does not
need to enclose any pavement remaining within a TPZ (in effect, the pavement
allows access within a TPZ, while serving as a superior root zone buffer). Fencing
should consist of 5- to 6-foot tall chain link mounted on 2-inch diameter steel posts,
which are driven into the ground for vertical alignment. Fencing shall remain in
place throughout site development, and will need to be installed, as needed, in
various phases (e.g. demolition is phase l, grading and construction phase 2). Also,
note that removing hardscape within a TPZ may trigger fencing being modified to
capture the newly exposed axea.
4.3 During Demolition, Grading and Construction
17. Take great caxe during demolition of existing pavement and other features to avoid
damaging a tree's trunk, crown and roots within a TPZ.
18. Great caxe must also be taken by equipment operators to position their equipment to
avoid trunks and branches, including the scorching of foliage. Any tree damage or
injury should be reported to the project arborist for review of treatment.
19. Avoid using the trees' trunks as winch supports for moving or lifting heavy loads.

DESArchitects + Engineers, Inc.
David L. Babby, Registered Consulting Arborist° January 25, 2020
20. Removing existing hardscape (including curbs and gutters) within a TPZ should be
carefully performed to avoid excavating roots and soil during the process, and
removal of base material shall be performed under direction of the project arborist
(and where necessary, shall remain in place and utilized as future base course).
21. Any authorized access, digging or trenching within designated-fenced areas shall be
foot-traffic only and manually performed without using heavy equipment or tractors.
22. Avoid damaging or cutting roots with diameters >2 inches without prior assessment
by the project arborist. Should roots of this size become encountered, within one
hour of exposure, either bury them with soil or wrap in moistened burlap, to remain
continually moist unril ultimately covered by soil. If approved for cutting, cleanly
severe at 90° to the angle of root growth against the cut line (using loppers or a sharp
hand saw), and then immediately after, bury the cut end with soil or cover with a
plastic sandwich bag (and secured using a rubber band, and removed just before
backfilling). Roots encountered with diameters less than 2 inches and require
removal can be cleanly severed, using a new handsaw or loppers, at 90° to the
direction of root growth.
23. Spoils created during digging shall not be piled or spread on unpaved ground within a
TPZ. If essential, temporarily pile spoils on plywood or a tarp.
24. New irrigation and lighting features (e.g. main line, laterals, valve boxes, wiring and
controllers) should be established so that no trenching occurs within a TPZ. In the
event this is not feasible, the trenches may require being installed in a radial direction
to a tree's trunk, and terminate a specific distance from a tnznk (versus crossing past
it). The use of a pneumatic air device (such as an Air-Spade�) may be needed to
avoid root damage. Additionally, any Netafim tubing used should be placed on
grade, and header lines installed as mentioned above. All routes within or near a TPZ
shall be reviewed with the project arborist several weeks/months prior to installation.
25. Digging holes for any new fence within a TPZ shall be manually performed, and in
the event a root of >2 inches in diameter is encountered during the process, the hole
should be shifted over by 12 inches and the process repeated.

David L. Babby, Registered Consulting Arboris� January 25, 2020
26. Dust accumulating on trunks and canopies during dry weather periods should be
periodically washed away (e.g. every three to four months).
27. Avoid disposing harmful products (such as cement, paint, chemicals, oil and
gasoline) beneath canopies or anywhere on site that allows drainage within or near
TPZs. Herbicides should not be used with a TPZ; where used on site, they should be
labeled for safe use near trees.
28. Fertilization may benefit a tree's health, vigor and appearance. If applied, however,
soil samples should first be obtained to identify the pH levels and nutrient levels so a
proper fertilization program can be established. I further recommend any fertilization
is performed under the direction and supervision of a certified arborist, and in
accordance with the most recent ANSI A300 standards.
