7.1 Tree Permit No. PL2017-40 — Under the authority of Diamond Bar Municipal
Code Section 22.38, the applicant and property owner requested a Tree
Permit to remove one protected California black walnut tree (Juglans
californica) and replace it with three California black walnut trees
(3:1 replacement ratio) on site, located at 2468 Alamo Heights Road. The
subject property is zoned Rural Residential (RR) with an underlying General
Plan land use designation of Rural Residential (RR).

AP/Nakajima presented staffs report and recommended Planning
Commission approval of Tree Permit No. PL2017-40 as recommended by
staff, Findings of Fact, and subject to the conditions of approval as listed in the
Resolution.
Chair/Wolfe asked if the arborist that provided the report included in tonight's
packet was the original arborist for the project. AP/Nakajima explained that a
Tree Permit was not required for the original application.
Chair/Wolfe asked if the requirement for fire access was new or should it have
been contemplated in the original proposed plans. AP/Nakajima said that a
copy of the original plans were forwarded to LA County Fire and that comment
regarding potential access was not provided to staff at that time.
MAY 9, 2017 PAGE 3 PLANNING COMMISSION
VC/Mok wanted to understand what was meant by a "period of time" for
monitoring with respect to Option #2 and whether that period of time included
the actual start of the project or if it was prior to the start of the project.
CDD/Gubman referred VC/Mok to the applicant's consulting arborist for a
response.
ChairANolfe opened the public hearing.
Christy Cuba, Arborist, Carlberg Associates said she went to the site,
conducted the inventory and prepared the report. She asked VC/Mok to repeat
his question which he did. Ms. Cuba explained that the monitoring would begin
when the project commenced (as soon as the grading permit is issued) and
the monitoring period would be determined by the City. Various jurisdictions
have different limitations they set on monitoring timeframes. Sometimes it is
through the construction period only whereas other jurisdictions require
additional monitoring beyond the period of construction (months or years) once
the project is complete and that would require monitoring reports to be
submitted to the City so that if a tree fails as a result of the encroachment,
conditions could be written in for replacement of the tree at that time or, written
in the Permit now.
VC/Mok asked how long, in Ms. Cuba's experience, it would take for a tree to
fail from the time mitigation measures were put in place.
Ms. Cuba responded that it is difficult to judge because California is just
coming out of a drought. With drought impacts trees have been suffering. And
the particular disease this tree has, evidence of a disease called Thousand
Cankers disease, some trees can withstand and continue to live or may decline
over a long period of time, but with construction impacts she believes the
disease would be exacerbated. She has seen trees with Thousand Cankers
disease that have declined over time anywhere from three to five years on
average. And construction impacts could take a couple of years to appear as
having impacted the tree.
VC/Mok said that with the issues this tree has and the angle at which it is
growing out of the slope he wondered if it could survive for many more years
with the two issues of the disease and the angle at which it is growing.
Ms. Cuba said it is her opinion that she does not believe it can survive because
of a combination of the grading that will be required, the amount of fill material
that needs to be placed under the canopy, the compaction and the retaining
wall under the tree, as well as the amount of pruning (a substantial portion of
the canopy) that will be required for fire access. Often in construction projects
such as this, arborists try to estimate in the field how much pruning will be
MAY 9, 2017 PAGE 4 PLANNING COMMISSION
necessary, but when one is onsite attempting to prune the tree to standard
arboricultural practices, where one might think it can be brushed up 14 feet but
with the grade change (lifting the grade), that 14 feet becomes much higher
and one does not want to merely cut a branch in the middle of the limb - it
needs to be cut back to another lateral branch that is growing out and
sometimes that significantly extends the amount of pruning one must do which
means it could go from 25 percent as indicated in the report to 50 percent of
that canopy at the time of pruning.
Chair/Wolfe said the plans likely already included the retaining wall and
compaction of the soil around the root base of the tree so the real issue tonight
is the pruning that is necessary to allow fire vehicles access in that area which
gets back to his earlier concern. It sounds to him like there are two distinct
issues with this tree, the latter being the pruning of the tree which could
irreparably injure the tree, but the former being something that perhaps should
have been addressed when this was in front of the Commission several years
ago, which is, the impact to the root structure of the tree by virtue of the
landscaping that was going to be done with the retaining wall compaction. He
recalled that the plan showed a golf cart running through that area. He asked
for clarification that this was all part of the original plan. AP/Nakajima said she
did not have the old site plan with her. However, from what she understands,
there was no access path proposed with the original application.
ChairMolfe said if they were going to put a retaining wall in, it had to be part
of the original approval and AP/Nakajima responded that she believed there
was a retaining wall proposed on the original site plan and asked if the architect
could offer her input.
Feng Xiao, Architect, verified that at the time the previous architect submitted
the first application on the old site plan, her firm was not involved. However,
she recalled that definitely there was no fire access from the north and for the
current retaining wall there was very detailed plans for a detailed grading plan
and retaining wall. That retaining wall close to the path came from one of the
HOA's comments that said it could not be graded more than two feet. Because
the grading plan was never finished in time to submit it for Planning
Commission review, she does not recall that there was a retaining wall at that
location. However., she does recall that there was a retaining wall on the south
side closer to the garage entry. Probably at that time, there was no detail level
grading plan/retaining wall plan generated and most likely no encroachment
issue would have been identified.
MAY 9, 2017 PAGE 5 PLANNING COMMISSION
ChairM/olfe asked the arborist how far away the fire access would have to be
away from the canopy of the tree to not impact the tree. Ms. Cuba responded
that the east canopy spread is approximately 20 feet, the southern canopy
spread is approximately 18 feet and the westerly canopy spread is about
30 feet. It is unbalanced to the west and the canopy is almost sweeping the
ground. And, there are multiple trunks. Typically, walnut trees do not respond
well to compaction, or cut or fill under the canopy. They tend to decline fairly
rapidly after more than a couple of inches of fill material. So, in this case since
there would have to be fill and a retaining wall, she would recommend that the
access road be about 20 feet away on the westerly side. There would be more
leverage because trucks would be coming up from the west and it would be
sloping up so that the grade, if she remembers correctly, could gradually come
up and move closer to the tree as the canopy spreads in. She reiterated
20 feet on the west and moving in 15 feet or so moving away from the trunk
and swinging back out. So, 20, 15 and 20 feet as one moves away from the
trunk. But again, it would depend on the amount of material that would need
to be placed under the canopy and still, there would need to be removal of a
great deal of that canopy.
C/Mahlke asked if Ms. Cuba was saying that the fill material called out in the
report is used for landscape, hardscape and residential design and from what
she understood Ms. Cuba to say, the fill material would do more of the damage
and the tree would not recover as readily from use of the fill material. Ms. Cuba
said it would be both the fill material and the canopy pruning that would
jeopardize recovery. C/Mahlke asked how much of the fill material was merely
for design and Ms. Cuba referred C/Mahlke to the Civil Engineer and Architect
for an answer to her question. C/Mahlke was asking if the fill material was less
and little pruning was done for the fire access with nothing being done to the
root system, would the chance of the tree's survival increase significantly and
Ms. Cuba said she would say yes, but if the orientation of the cart path remains
where it is she is not sure how that would be accomplished. She pointed out
the grade differential on the photograph of the tree and pointed out that the
current plan shows that a rock wall and an eight -foot wide DG cart path will be
located approximately five feet (5) south of the trunk, and if that position needs
to be she is not sure how it could be engineered to not require fill be
placed there given the existing topography.
Robin Smith spoke about the Migratory Bird Treaty Act. She reviewed the tree
report for this project and believed the arborist had done a superb job in
assessing the situation. She asked the City to explain the policy on trimming
and removing trees, especially protective native trees during nesting season
which
MAY 9, 2017 PAGE 6 PLANNING COMMISSION
is February to August. She mentioned that many birds in the City nest all year
round. Does the City of Diamond Bar uphold the"Migratory Bird Act which
protects nesting birds, both resident and Migratory? She agrees the tree
probably needs to be removed but she is very concerned about when that
removal will occur. Related to that, if the Commission were to say no nests
have been found in the tree she would like to see evidence because she
believes there is supposed to be a report that produces evidence for or against
a nest being in an existing tree. The problem is, tree removal and trimming in
spring and early summer is irresponsible and possibly illegal. It can damage
trees and devastate nesting birds. Cutting, trimming and pruning during spring
and early summer can lead to diseased trees and intrusions of pests that harm
trees. Hawk nests are large and visible, but the majority of song bird nests are
small and camouflaged. Tree trimmers may not see the nest until it is too late
and loud activity can frighten birds and cause them to starve, vacate the nests,
etc. The Migratory Bird Treaty Act says that birdsin active nests are protected
from harm or harassment. California Fish and Wildlife and the U.S. Fish and
Wildlife Service may issue citations and levy fines to individuals or companies
that disregard these regulations. Solutions to help trees and birds would be a
list of things that can be done to improve the environmental integrity of the City
which are, trim and prune during the fall and winter when trees are dormant,
hiring arborists, landscapers and trimmers who consider the health of trees
and birds that nest in them, which is declared in their specified written service
agreements, and avoid contracting services that only trim trees that work all
year around. Citizens are advised to act if they see tree trimmers disturbing
an active nest by taking a picture of the nest or the destruction and the
company's name and report violations to the Fish and Wildlife Service number.
She said she wanted to remind the City that a single tree, native or ornamental
is an ecosystem in and of itself. It is part of a larger habitat which is a critical
participant to the entire City ecosystem. So in an effort to preserve and
conserve the environmental integrity she asks the Commission to learn more
about ecological literacy and the science which teaches that these elements
are all connected. When a single tree is trimmed during certain seasons it
does impact both immediate and cumulative. She is very curious to
understand what the City would do to update its Tree Removal Permits to
consider the risk of wildlife related to tree or habitat removals.
Chair/Wolfe closed the public hearing.
C/Mahlke felt she did not know enough about Option 2 and also felt the Arborist
had done such a thorough job that there was likely little hope for the tree. She
was concerned that if the tree is lost and there is no replacement consideration
MAY 9, 2017 PAGE 7 PLANNING COMMISSION
it will not be replaced. Therefore, if the tree will be lost, the Commission needs
to preemptively make sure the replacement option is in place. Therefore, she
will make a motion to Option 1 as recommended by staff.
Chair/Wolfe said that he came to tonight's meeting with concerns which the
Commission heard. When he looked at the plan and the reason for the Tree
Permit he asked for the site plan to be put back up because he was trying to
understand if there was another way the access could be accomplished. He
suspects there might be another way to go about providing the fire access that
would, to some degree, change the frontage of the property and given the
commentary from the Arborist about the current condition of the tree, he is not
sure it is worth the effort and therefore agrees with C/Mahlke that the City
would not get anything in return. Staffs recommendation to remove this tree
and replace it with three trees of the appropriate size leads him to second the
motion.
VC/Mok said he visited the site today and walked up to look at the tree from
all angles. The location of the tree is awkward and the way it is growing out of
the slope it appeared to him that with a strong wind or more rain it would topple
over. He walked fairly close to the trunk and noticed all of the problems the
Arborist opined. The other trees are very small and spindly and not protected.
After viewing the tree up close it would certainly impact the project and its
progression.
C/Mahlke moved, Chair/Wolfe seconded to approval of Tree Permit
No. PL2017-40 as recommended by staff, with the Findings of Fact, and
subject to the conditions of approval as listed within the Resolution. Motion

10. STAFF COMMENTS/INFORMATIONAL ITEMS:
10.1 Public Hearing dates for future projects.
CDD/Gubman said that the next Planning Commission is scheduled for
May 23 with three items on the agenda. The annual budget will be headed to
the City Council in June (the General Fund budget and Capital Improvement
Program budget) and under state law, before the City Council can adopt the
Capital Improvement Plan, the Planning Commission is charged with
reviewing the list of proposed projects and determining that the CIP is
consistent with the General Plan. PWD/Liu will be in attendance to answer
any questions the Commissioners might have about the projects listed in the
report. In addition, there are two routine land use proposals on the agenda,
an addition to an existing single family residence at 3372 Falcon Ridge Road,
and a Conditional Use Permit for a chess tutoring facility on the second floor
of the commercial building at the corner of Grand Avenue and Diamond Bar
Boulevard.
The next General Plan Advisory Committee meeting is scheduled to be held
on Thursday, June 15 in the Windmill Room at 6:30 p.m. which will be
advertised through social media and via the Diamond Bar Newsletter. The
topic of the next meeting will be the beginning of Phase II where the Committee
will consider the feedback from the outreach and reconnaissance phase and
will begin considering land use alternatives which will be anchored around
potential locations for a "town center" in which there was much interest and
positive response during the outreach efforts i.e., that Diamond Bar should
have a "there -there". The first phase identified three potential "town center'
locations that will be the cornerstone of a broader land -use plan which will
include a broader plan for mixed-use zones and other facilities of community
interest where the land inventory and existing development conditions might
accommodate such zones. The GPAC is not being asked to select a preferred
alternative but rather receive more conceptual information to begin getting
feedback from the members as to whether the process has started at the right
point of departure and if so, what various aspects of the various alternatives
seem to be more preferable after which the process will continue to work
toward refinement of a "preferred" alternative. This portion of the project will
move into 2018 and when a preferred land -use plan has been developed, staff
will begin drafting the General Plan document with all of its goals, objectives
and policies, and begin working on the EIR. This process is still on track for
adoption of an updated General Plan in late spring/early summer of 2019.
