MEMORANDUM
TO: PLANNING COMMISSION
FROM: GEOFF ENGLISH, DIRECTOR OF PUBLIC WORKS
SUBJECT: TREE REMOVAL TIMELINE FOR TRACT 3054 – 1029 ASH STREET
DATE: FEBRUARY 7, 2017
RECOMMENDATION:
It is recommended that the Planning Commission review the attached tree removal
timeline for Tract 3054 – 1029 Ash Street.
IMPACT ON FINANCIAL AND PERSONNEL RESOURCES:
Financial impacts include staff time and resources of approximately $1,000 to research,
prepare and present the information requested by the Planning Commission.
BACKGROUND:
A development project at 1029 Ash Street, (Tract 3054) was submitted on September
26, 2014 to City of Arroyo Grande and routed through the entitlement process. The
Planning Commission approved this development project on May 5, 2015 subject to
Conditions of Approval. The property owner(s) initiated the tree removal process
associated with the project, subject to the Conditions of Approval and interacted with the
Public Works Department on monitoring and compliance matters related to the
associated tree removals.
On October 4, 2016 the Planning Commission requested information regarding the Tree
Removal Permits issued by the Public Works Department for 1029 Ash Street and
related tree removal matters.
ANALYSIS OF ISSUES:
Per the Planning Commission’s request, a timeline of tree removal related activities at
Tract 3054 was prepared and will be presented. The tree removal activity at this
project site included both permitted and non-permitted removals. One non-permitted
tree removal, resulted in the issuance of a fine to the property owner and the
requirement for mitigation tree planting in accordance with the City of Arroyo Grande
Community Tree Program Ordinance, a copy of which is attached. Copies of the
various tree removal permits and corresponding City responses are also included as
attachments to this report, along with relevant Arborist reports.

FOOTNOTE(S):
--- (1) ---
Editor's note— Section 1 of Ord. No. 656, adopted Aug. 27, 2013, amended Ch. 12.16 in its entirety to
read as herein set out. Former Ch. 12.16, §§ 12.16.010—12.16.090, pertained to similar subject matter
and derived from prior code §§ 10.3.01—10.3.09; Ord. 521, § 1, adopted in 2000; Ord. 567, § 2, adopted
in 2005; Ord. 575, §§ 1—4, adopted in 2005; Ord. 585, §§ 2—3, adopted in 2007; and Ord. 606, §§ 2—4,
adopted in 2008.
12.16.010 - Purpose.
It is in the best interest of the city, the public, and the environment to establish a comprehensive
community tree program that promotes:
A. The preservation, the maintenance, and regeneration of all trees;
B. A beautiful and aesthetically pleasing community;
C. Trees or groves of unique or historical value and wildlife habitat;
D. Educational programs that address the importance of trees in the environment and their role in
purifying the air, providing shade, controlling erosion, and maintaining the rural, small town
atmosphere;
E. Improved communication between the parks and recreation commission, architectural review
committee and planning commission regarding tree related issues and concerns.
Further, in order to implement the goals and objectives of the parks and recreation element of the
city of Arroyo Grande's general plan, and to mitigate the loss of open space and vegetation caused by
new development in the city, the city council has determined that a development impact fee (or the
implementation of a tree planting plan in lieu thereof) is needed in order to finance the planting of trees
and to pay for the development's fair share of the implementation of these improvements.
This chapter establishes policies, regulations and specifications necessary to govern installation,
maintenance and preservation of trees to accomplish the above stated purpose.
(Ord. No. 656, § 1, 8-27-2013)

12.16.090 - Installation, maintenance and removal of trees relating to property development.
A. A tree planting fee is established on issuance of all subdivision maps for development in the city. The
city council shall, in a council resolution, set forth the specific amount of the fee. As described in the
fee resolution, this tree planting fee shall be paid by each developer prior to issuance of a building
permit. On an annual basis, the city council shall review this fee to determine whether the fee
amounts are reasonably related to the impacts of developments. The revenues raised by payment of
this fee shall be placed in a separate and special account, and such revenues, along with any
interest earnings on that account, shall be used solely to pay for the city's future purchase and
planting of trees described in the resolution enacted pursuant to the above. The selection, purchase,
planting and future maintenance of such trees shall be p erformed by the director. In lieu of the fee, at
the election of the planning commission, the subdivider shall be responsible for the purchase,
planting, maintenance and replacement, if necessary of such trees for twenty-four (24) months after
planting and acceptance according to a uniform planting plan approved by the director. The
subdivider may be required to post a bond, the amount to be determined by the planning
commission, to assure faithful performance. The bond may be held by the city for a maximum of two
years.
B The planning commission may require a six -foot tree planting easement on all or select streets within
proposed subdivisions, in addition to dedicated planting easements for street trees in conformity with
a uniform planting plan for the area involved.
C. All proposed changes in a public street right-of-way direction or width, or any proposed street
improvement, shall, where feasible, include allowances for planting easements. Plans and
specifications for planting such areas shall be integ rated into the general plan of improvements, and
it shall be the duty of the director of public works to coordinate the design of such improvements with
the community development director prior to the completion of the final overall plans.
D. No tree shall be removed on any undeveloped parcel for which a tree removal permit has not been
issued or for which a tree removal plan has not been approved by the planning commission. Tree
removal on undeveloped property without a permit or approved plan shall const itute a misdemeanor,
and in addition, removed trees shall be replaced through payment, by person or persons causing
such loss, to the city. The amount of such payment shall be the replacement value of the tree, as
determined by the director, but in no event shall it be less that one hundred fifty dollars ($150.00) per
tree, and it shall be in addition to any criminal fine or penalty for municipal code violation.
E. All grading, building, conditional use, tract map, parcel map, planned development, and othe r
development proposals submitted to the city shall be accompanied by an accurate map identifying
and locating all existing trees upon the property for which application is received and all existing
trees that are off-site but affected by the project. Such map shall also identify all existing trees that
are proposed by the applicant for removal or destruction, and such trees shall be visibly marked for
the director's inspection. The director, or his or her designee, shall locate all trees upon the
applicant's and affected property and prepare a written report to the permit-granting authority within
two calendar weeks of the permit application having been received by the city.
F. The director's report to the permit-granting authority shall contain:
1. Recommendation as to which trees should be preserved and protected from removal and/or
relocation;
2. Recommendation as to which trees should receive landmark designation.
G. The permit-granting authority shall not issue a permit until receiving and reviewing the director's
recommendations. The permit-granting authority shall not be bound to honor the director's
Page 8
recommendations. The permit-granting authority shall have the authority to approve and issue a
permit with conditions requiring protection and preservation of any or all trees affected by the permit.
H. The killing, removal or damaging, intentionally or accidentally, of any tree, because of development
activity, shall result in a separate administrative penalty to be paid, through payment by person or
persons causing such loss, to the city. The payment shall be the amount of the value of the tree, as
set forth in the Manual for Plant Appraisers, published by the Council of Tree and Landscape
Appraisers, but in no event shall the payment be less than one hundred fifty dollars ($150.00) per
tree. The intentional killing, removal or damaging of any tree, as a result of development activity,
shall constitute a misdemeanor.
I. If the permit-granting authority approves the removal of any oak tree or other tree as defined in
Section 12.16.020 when related to property development, the tree owner(s) of such tree(s) shall
replace each tree removed at a three to one replacement ratio. The size, specie, and location of
replacement trees shall be determined by the director, in writing, before the permit is issued.
Replacement trees shall be maintained and cared for by the owner(s) when planted on his or her
parcel. If not planted on the owner's parcel, the director may identify a site for planting replacement
tree(s), and the city will be responsible for maintenance thereof.
J. In the event the permit-granting authority desires landmark designation for any tree, the permit-
granting authority shall convey such recommendation to the city council via the planning commissio n
for consideration and recommendation and shall withhold issuance of such permit until the city
council has adopted a resolution conferring landmark designation.
K. In the event the city council adopts a resolution conferring landmark designation upon a tree(s)
during the development process, a permit shall be issued only with condition that the designated
tree(s) shall not be removed or disturbed. Failure to comply with this condition shall result in a
misdemeanor. There will be a separate administrative penalty of five thousand dollars ($5,000.00) to
the tree owner for each landmark tree removed, destroyed or killed as a result of construction or
development activity, regardless of whether the removal was intentional.
L. All administrative penalties recovered by the city, pursuant to this chapter of the municipal code,
shall be deposited in a city fund, the assets of which shall be used for tree planting, care and
administration of this chapter of the municipal code.
M. Trees designated to remain on the tree removal plan shall be protected prior to and during
construction by the owner(s), using the following measures:
1. Each tree or group of trees designated to remain shall be protected by an enclosure of a five -
foot fence, prior to the beginning of construction. The fence shall be wooden, chain link, or
plastic barricade fencing. The location of the fence is normally at the dripline of the tree, but it
may adjusted or omitted with the director's written approval.
2. No parking of vehicles or equipment or storage of materials shall be permitted within the dripline
of the trees designated to remain.
3. In the event the underground utilities must be placed within the dripline of the trees to remain,
the utilities shall be installed by auguring at twenty-four (24) inches minimum depth or by hand
trenching. If roots over one inch in diameter are encountered, the roots shall be preserved
without injury. No machine trenching within a tree's dripline shall be permitted, unless
authorized, in writing, by the director.
4. A performance bond may be required, in a form acceptable to the city and prior to issuance of
an entitlement, to assure protection of trees on the site. The amount of any set bond shall be
one thousand five hundred dollars ($1,500.00), or the value of affected trees, whichever is
greater, based on the Manual for Plant Appraisers, Council of Tree and Landscape Appraisers.
The latest edition is to be available for review in the community development department. If, in
the opinion of the certified arborist, no violation or damage has occurred during construction, the
bond shall be returned upon final building inspection. However, if damage has occurred, the
Page 9
bond shall be held for three years and forfeited if, in the opinion of the certified arborist ,
permanent damage has occurred.
5. Failure to comply with tree preservation requirements shall result in the director issuing a stop
work order until all requirements have been met.
N. Upon determination that a conditioned tree or landmark tree has died, been destroyed or removed as
a result of construction or development activity, the council may stop further construction or
development activity until the administrative penalty is paid.
O. When the city requires tree pruning, the tree service contractor performing the work shall use an
arborist certified by the Western Chapter of the International Society of Arboriculture.

SUMMARY
ARBOR FIRST
TREE PROTECTION PLAN
1029 ASH STREET
ARROYO GRANDE, CA
Proposed construction plans have been designed to incorporate a private drive as well as construction
of single family residences at 1029 Ash Street, Arroyo Grande, CA. Ordinance 575 §12.16.010 thru
12.16.090 of the City of Arroyo Grande Municipal code deals with the policies, regulations and
specifications relating to trees within the city. There are Coastal Live Oak trees (see inventory below)
that will be potentially impacted by the proposed construction. To ensure the protection of retained
trees in the construction area, tree protection measures (Tree Protection Plan [TPP]) as outlined below
must be fully integrated into the development process. Tree protection must be a consideration during
all construction phases an d post-construction activities.

SEQUENCE OF EVENTS
The following sequences are governed by operational constraints and are subject to change. The
Arborist of record must be noted regarded any changes to this sche dule:
B4
Pre-development Stage
• Pre-commencement site meeting including Arbori st of record, local planning authority,
developer, contractor and all sub-contractors. This meeting must take place before any
development activity to confirm the timing and implementation of the Tree Protection
measures.
• Removal of trees designated in the approved development plans by Arborist of record.
• Arborist of record pruning of trees to be directly impacted by development ie skirting
for construction equipment clearing and removal of dead wood that could be dislodged
during construction.
• Determination of Root Protection Areas (RPA's) for construction of protective fencing
Development Stage
• This stage is subject to site monitoring visits by the Arborist of record at intervals as
agreed at the pre-commencement site meeting. These visits are to ensure that the
agreed protection measures are functional and correctly achieving their purpose.
• Site accessible to demolition and construction traffic.
• Development commences and progresses to completion.
• Removal of protective fencing as agreed by the Arborist of record
• Landscape contractors to be briefed by Arborist of record. Hard and soft landscaping
installed un der Arborist of record review.
TREE PROTECTION PLAN DETAILS
• Construction work shall be avoided, wherever possible, within the driplines of the Oak trees.
The Arborist of record shall be present during all construction operations within 10 feet of the
dripline of any trees to be retained.
• Tree Protective fencing shall be erected prior to the beginning of construction to protect the
Critical Root Zone (CRZ) of each retained tree. The CRZ is defined as twelve (12) inches of radius
for each one (1) inch of Diameter at Standard Height (DSH). The location of the fence shall be a
minimum radius of eight (8) feet from the trunk of the tree, except for trees shown on the plan
to have construction within the drip line. Fence shall consist of minimum five (5) foot high chain
link or vinyl fencing mounted on 6 foot steel "t" posts spaced not more than 10 feet apart. Tree
protection area signs (see example of language below) shall be affixed to all tree protection
fencing at 50 foot spacing average.
• Permits for removal of trees are to be posted and visible from the street. Trees to be removed
shall be identified with red or yellow flagging. Trees designated to be removed shall be
removed by Arborist of record to minimize potential for damage to remaining trees and roots.
• Root pruning may be necessary on those trees in which grading cuts are placed within the drip
line. The exact location and depth will be determined by the project Arborist of record during
the pre-construction meeting. The Certified Arborist shall prune roots over 1 inch in diameter
within the Critical Root Zone (CRZ) of the trees. All cuts shall be clean with no frayed edges.
International Society of Arboriculture (ISA) pruning standards shall be followed in all instances.
• No toxic materials shall be stored within 100 feet of tree protection areas.
• Mechanized equipment use shall be minimized as much as possible in any tree protected area.
B4
• All areas within the CRZ of the trees that can be fenced sh all receive a 4-6 inch layer of chip
mulch to retain moisture, soil structure and reduce the effects of soil compaction. Mulch shall
not contact trunk of the trees.
• The Arborist of record shall make regular weekly inspections during active construction and
demolition and provide reports to the owner and contractor. Reports shall document condition
of tree protection devices and provide recommendations for maintenance and/or additional
care.

RE: 1029 Ash Street, Arroyo Grande, CA -Tree Assessment.
Assignment: To assess three (3) red flowering gum (Corymbiaficio/ia) regarding general health and
structure in relation to a proposed housing development east of the trees.
Limits of inspection: This inspection was ground based only.
Three trees along the west side of a the lot at 1029 Ash Street were marked with blue paint by the City of
Arroyo Grande to see if any would be able to be retained in the landscape. I assessed each tree for overall
heath and structure. My assessment was from north to south along the western border of the property. The
following are my findings for each tree:
Tree #1-The tree had a 55 inch DBH and height of approximately 65 feet. The foliage had healthy green
color. No pests were observed. The trunk and roots of the tree appeared to be sound. A large scaffold
branch on the east side of the tree had multiple, vertical, stress-fractures ranging between 1 and 4 feet in
length. No significant Jean was noted.
Tree #2-The tree had a 32 inch DBH and height of approximately 50 feet. The foliage had healthy green
color. No pests were observed. The trunk and roots of the tree appeared to be sound. The tree is smaller
than others in the stand making subordinate. At approximately 12 feet above ground is where two co-
dominant branches originate. Between the co-dominant branches is an area of included bark, indicating
weak attachments.
Tree #3-The tree had a 36 inch DBH and height of approximately 65 feet. The foliage had healthy green
color. No pests were observed. Minor signs of decay were beginning. Although there was callusing
around the wound, full closure will take several years. At the base of the trunk on the west side there was
also an older wound approximately 1 foot in diameter. Above the wound there was a stress fracture that
appears to have occurred a few years in the past due to the callous developing near it. This tree also has a
Jean of approximately 13 degrees to the west.
Analysis & Recommendations:
Tree #1 has major structural weaknesses in the scaffold branch on the east side of the canopy. In order to
mitigate this haz.ard, a substantial section of the canopy (30% to 40%) would have to be removed. The
tree would be aesthetically unpleasing at that point. Additionaly, i:e-growth branches at the cut points
would be loosely attached and have a potential to fail toward homes proposed to be situated to the east. I
recommend full removal of this tree.
D2
Tree #2 is a smaller stature tree in comparison to the others surrounding it. It also has co-dominant
branching structure with included bark. When other trees in the stand are removed, this tree will be
exposed to prevailing winds and the co-dominant stems and possibly the roots will have more potential to
fail toward homes proposed to be situated to the east. I recommend full removal of this tree.
Tree #3 has two wounds at the base of the trunk with minor signs of decay. These wound areas are not
likely to close over before significant decay becomes established and continues to weaken the base of the
tree. At the north side of the tree, above the wound, there is a stress crack with some signs of callusing.
The crack indicates that this tree shifted to the east at some point. Additionally, the tree has a lean of
approximately 13 degrees. Based on the decay points, stress fracture and degree of lean, and the
proximity of the tree to proposed housing, I recommend full removal of this tree.

Rodney D. Thurman

as well as construction of single family resid\!nc~s. The following issues ha\·e been addres~d as
requc~ted:
Grading fill over root zones of trees

Con~truction ~itbin oak tree root zones
As a general rule . construction within the CRZ can take place given a proper Site Tree
Protection Plan is impl~mented. This plan :should include, but not be limited to: locating roots
to be pruned prior to commencing construction; hand pruning roots over 1" in diameter v.-ithin
the CRZ; r~view of deep excavations by certified arhorist of record for proper handling of roots
exposed. Other factors also can influcn<'e the extent to which a tree can tolerate injury to their
roots. Age, health and vigor V\.ill play a major role in ho\l\. a tree reacts to construction activities.
Additionall), pruning to correct imrn~p\!r pre\ious pruning and neglect of the remaining trees
would result in the improvement of their overall health. The construction activities as proposed
coupled V\.ith the recommendation for removal of trees #6 & #12 would not have advcrs~ effects
on the remaining trees.
Access to Lot 7 and impact to trees
The i~sue of access to Lot 7 has been addressed in section Impact to trees within and adjacent

Fencing impacts on property line~
This is out~ide the scope of a C'crtitieJ Arborist Fencing impacts on property lines need to be
addressed with the d~veloper.
Trees located across multiple lots
Ba:;~d upon wrrent tract map, in no instance will trees ~hose drip linec; cross multiple lots have
33% of their root zones impacted b) proposed construction.

RE: TRACT 3054
Dear Mr. Reilly:
In previous site monitoring, we have had to prune roots after excavation. Any roots greater than one
inch ( 1 ") [ previous norm was 2" but has subsequently been changed to l "] are clean cut to no frayed
edges or cracks to prevent fungus from forming. Current literature and industry experts agree that
this is the proper methodology for handling construction under driplines of trees. Depending on
percentages of root loss, a whole tree health program can be introduced. Monitoring these roots has
proven that they do very well healing.
Sincerely,
