MOORPARK CITY COUNCIL
AGENDA REPORT
TO: Honorable City Council
FROM: Jeremy Laurentowski, Parks and Recreation Director
DATE: 06/05/2024 Regular Meeting
SUBJECT: Consider Waiving the Formal Request for Proposals (RFP) Process for
Tree Maintenance Services in Accordance with City Municipal Code
Chapter 3.04.120; and Award of Agreement for Tree Maintenance
Services to West Coast Arborists, Inc.
BACKGROUND
Historically, the City of Moorpark (City) has contracted with licensed contractors to provide
tree maintenance services for the approximately 13,000 trees located in the City’s various
landscape maintenance districts, parks and other City maintained properties. Tree
maintenance services generally focus on work to maintain the City’s tree canopy such as
trimming and pruning, as well as emergency services for public safety. The City’s current
contract for tree maintenance services is with West Coast Arborists, Inc. (WCA) and
expires on June 30, 2024.
The California Public Contract Code (PCC) establishes that landscape maintenance work
related to trimming, pruning, and replacement of plants is not considered a “public project”
(PCC 22002(d)(4)), and is therefore not subject to the PCC’s public bidding requirement.
Tree planting work, which could be regarded as “public project” work under the PCC, is
exempt from competitive bidding when the work does not exceed $60,000 (PCC 22032).
It should be noted that staff generally obtains separate bids for tree planting and rarely
performs such work under the tree maintenance contract. As a result, the City’s tree
maintenance services are not subject to public bidding under the PCC. Contracting for
these services does, however, require compliance with the Moorpark Municipal Code
(MMC). On July 17, 2019, the City Council approved Resolution No. 2019-3829
establishing procedures for the procurement of professional and other contractual
services that are exempt from the bidding procedures for supplies and equipment set forth
in Chapter 3.04 of the MMC. The procedures prescribed in this Resolution generally
follow guidelines set forth in Chapter 3.04, however, Chapter 3.04.120 of the MMC allows
the City Council, by majority vote, to “waive the purchasing procedures or alter these
Item: 10.M.

proceedings to fit a specific purchase, when such waiver is not in violation of state law.
(Ord. 16 § 1, 1984)”
On January 11, 2024, the City of Carpinteria released a request for proposals (RFP) for
tree maintenance services that substantially matches the services that the City requires
for its citywide tree maintenance program. These services include general tree trimming,
removal, replacement, and emergency services. Carpinteria received two bids for tree
maintenance services and, in February, 2024, awarded a contract to WCA based, in part,
on the fact that they offered the lowest cost service proposal.
DISCUSSION
The Carpinteria RFP for tree maintenance services provides the City an opportunity to
piggy-back on WCA’s proposal and negotiate a separate contract for tree maintenance
services. The WCA proposal includes a range of services that covers the City’s tree
maintenance needs, including general and clearance pruning, tree and stump removal,
tree planting, and emergency services. Additionally, WCA currently manages the City’s
tree inventory and maintains information about the City’s tree population through their
proprietary software (ArborAccess). The use of ArborAccess is provided at no cost to the
City and tracks information such as tree location, species, height, diameter, and work
history. The tree inventory includes global coordinate data, allowing staff the ability to
manage the City’s inventory and maintenance needs through mobile devices. Because
the tree inventory is tracked utilizing global coordinate data, the inventory could be
integrated with the City’s Geographical Information System (GIS) program in the future.
WCA has held tree maintenance contracts with the City since 2000. Staff has been
satisfied with their performance and contracts separately with WCA for various arborist
services, such as the completion of the annual High Street Pepper Tree Report. Staff
has reviewed WCA’s Carpinteria proposal and feels that the service rates are competitive
and cost effective. The most notable cost changes are the regular maintenance costs
associated with Grid Trimming and Crew Rentals. The Carpinteria proposal for Grid
Trimming is approximately 8% less than the rate provided in WCA’s current agreement.
Crew Rental and Emergency Crew Rental (overtime) rates have increased by 8% and
5% respectively. However, even though the new Crew Rental rates are higher than
WCA’s current contract, staff anticipates that the City will realize significant annual
savings. This is due to the fact that the Carpinteria proposal provides a provision whereby
Grid Trimming costs are utilized when there is a grouping of seven (7) trees or more within
a 200-yard radius. The City’s current contract with WCA does not provide a similar
provision and therefore the contract generally requires Crew Rental rates for work within
the parks, on slopes, or other difficult to reach locations. In FY 2023/24, the City paid
Crew Rental rates for approximately 89% of the trees that were trimmed in the City.
However, staff estimates that approximately 30% to 40% of the City’s tree inventory would
now fall under Grid Trimming, resulting in savings to the City. It is somewhat difficult to
estimate the actual savings that the City would realize since the variety of services differ
427

from year to year. However, staff believes a conservative estimate would yield savings
of approximately 10% to 20% annually. The following is a comparison of WCA’s
Carpinteria cost proposal and the rates under the City’s current contract:

Although WCA’s Carpinteria proposal is generally equivalent to the City’s current contract,
several items were not included in the Carpinteria RFP. Because of this, staff contacted
428
Honorable City Council

WCA in order to obtain pricing for several additional items. As noted earlier, staff will
typically obtain bids for tree planting services from several contractors in order to
guarantee competitive pricing for these services.

It should also be noted that the Carpinteria RFP provides several contract provisions that
will be beneficial to the City. Within three (3) months after execution of the Agreement,
the bid documents require a complete update of the City’s tree inventory. The City’s tree
inventory was completed approximately three years ago and since then, trees have been
removed, replaced and have been treated for various diseases and pests. The update
will verify all trees are included in the inventory, confirm species and health conditions,
re-measure the tree height, trunk diameter and canopy spread, and include any trees that
may have been missed during the initial inventory. Additionally, the Carpinteria RFP
includes the completion of a Five-Year Tree Maintenance Plan (TMP). The TMP will
utilize the tree inventory to prioritize a grid trimming schedule for each of the City’s trees
over a five-year cycle. The TMP will identify any trees recommended for removal, and
options for replacement, as well as an estimated annual cost for each planning year.
The City Attorney has reviewed staff’s proposal to piggy-back on WCA’s Carpinteria
proposal, and confirmed that tree maintenance service, including tree planting work that
does not exceed $60,000 per year, is not subject to the public bidding requirement of the
PCC. The City Attorney concurs the City Council may waive the formal RFP process
based on the aforementioned guidelines established in Chapter 3.04.120 of the MMC.
WCA has confirmed that they are willing to honor the terms in their Carpinteria proposal.
The contract term would be for one (1) year, with an option to extend the contract for four
(4) additional one (1) year periods. The agreement includes a cost adjustment at year
three (3) and year five (5) of the agreement, whereby WCA’s rates may be increased by
an amount not to exceed the annual percentage change in the Consumer Price Index
(CPI), All Urban Consumers in the Los Angeles-Riverside-Orange County, CA Area, from
January of the prior year to January of the current year, or 5 percent (5%), whichever is
429

less. The contract value will remain at $350,000 annually, for a total potential contract
value of $1,750,000 over the 5-year extended term.
WCA has the required experience and possesses the necessary licenses to perform tree
maintenance services. Staff is recommending that the City Council waive the formal RFP
process and award a contract for tree maintenance services to WCA.
ENVIRONMENTAL DETERMINATION
This action is exempt from the California Environmental Quality Act (CEQA) as it does
not constitute a project, as defined by Section 15378 of the State CEQA Guidelines.
Therefore, no further environmental review is required.
FISCAL IMPACT
Funding for tree maintenance services in the City’s parks, landscape maintenance
districts, and other City maintained properties is included in the FY 2024/25 Operating
Budget. No additional appropriation is requested at this time.
COUNCIL GOAL COMPLIANCE
This action does not support a current strategic directive.

the Contractor’s office and upon reasonable written request by the City, the necessary
computer software and hardware for purposes of accessing, compiling, transferring, and

officers, employees, and agents (“City Indemnitees”) from and against any and all causes
of action, claims, liabilities, obligations, judgments, or damages, including reasonable
legal counsels’ fees and costs of litigation (“claims”), arising out of the Contractor’s
performance of its obligations under this Agreement or out of the operations conducted
by Contractor, including the City’s active or passive negligence, except for such loss or
damage arising from the sole negligence or willful misconduct of the City. In the event the
City Indemnitees are made a party to any action, lawsuit, or other adversarial proceeding
arising from Contractor’s performance of this Agreement, the Contractor shall provide a
defense to the City Indemnitees or at the City’s option reimburse the City Indemnitees
their costs of defense, including reasonable legal counsels’ fees incurred in defense of
such claims.
Contractor agrees to obtain executed indemnity agreements with provisions
identical to those set forth in this Section from each and every subcontractor, or any other
person or entity involved by, for, with, or on behalf of Contractor in the performance of
this Agreement. In the event Contractor fails to obtain such indemnity obligations from
others as required here, Contractor agrees to be fully responsible according to the terms
of this Section. Failure of City to monitor compliance with these requirements imposes no
additional obligations on City and will in no way act as a waiver of any rights hereunder.
This obligation to indemnify and defend City as set forth here is binding on the successors,
assigns, or heirs of Contractor and shall survive the termination of this Agreement or this
Section.
City does not and shall not waive any rights that it may have against Contractor by
reason of this Section, because of the acceptance by City, or the deposit with City, of any
insurance policy or certificate required pursuant to this Agreement. The hold harmless
and indemnification provisions shall apply regardless of whether or not said insurance
policies are determined to be applicable to any losses, liabilities, damages, costs, and
expenses described in this Section.
This Indemnity shall survive termination of the Agreement or Final Payment
hereunder. This Indemnity is in addition to any other rights or remedies that the
Indemnitees may have under the law or under any other Contract Documents or
Agreements. In the event of any claim or demand made against any party which is entitled
to be indemnified hereunder, City may, in its sole discretion, reserve, retain, or apply any
435
West Coast Arborists, Inc. Page 6 of 48
monies to the Contractor under this Agreement for the purpose of resolving such claims;
provided, however, City may release such funds if the Contractor provides City with
reasonable assurance of protection of the Indemnitees’ interests. City shall, in its sole
discretion, determine whether such assurances are reasonable.
11. INSURANCE
Contractor shall maintain prior to the beginning of and for the duration of this
Agreement insurance coverage as specified in Exhibit A attached hereto and incorporated
herein by this reference as though set forth in full.
12. INDEPENDENT CONTRACTOR

Contractor. The personnel performing the services under this Agreement on behalf of
Contractor shall at all times be under Contractor’s exclusive direction and control. Neither

Contractor or any of Contractor’s officers, employees, or agents, except as set forth in
this Agreement. Contractor shall not at any time or in any manner represent that it or any
of its officers, employees, or agents are in any manner officers, employees, or agents of
the City. Contractor shall not incur or have the power to incur any debt, obligation, or
liability against City, or bind City in any manner.
No employee benefits shall be available to Contractor in connection with the
performance of this Agreement. Except for the fees paid to Contractor as provided in the
Agreement, City shall not pay salaries, wages, or other compensation to Contractor for
performing services hereunder for City. City shall not be liable for compensation or
indemnification to Contractor for injury or sickness arising out of performing services
hereunder.
13. LEGAL RESPONSIBILITIES
The Contractor shall keep itself informed of local, state and federal laws and
regulations which in any manner affect those employed by it or in any way affect the
performance of its service pursuant to this Agreement. The Contractor shall at all times
observe and comply with all such laws and regulations, including but not limited to the
Americans with Disabilities Act and Occupational Safety and Health Administration laws
and regulations. Contractor shall comply with all applicable provisions of the California
Labor Code, including those set forth in Exhibit B. The City, and its officers and
employees, shall not be liable at law or in equity occasioned by failure of the Contractor
to comply with this Section.

Neither the Contractor, nor any subcontractor under the Contractor, shall
discriminate in employment of persons upon the work because of race, religious creed,
color, national origin, ancestry, physical disability, mental disability, medical condition,

436
West Coast Arborists, Inc. Page 7 of 48
sexual orientation, or military and veteran status of such person; or any other basis
protected by applicable federal, state, or local law, except as provided in Section 12940
of the Government Code. The Contractor shall have responsibility for compliance with
this Section, if applicable [Labor Code Sec. 1735].

Contractor declares and warrants that no undue influence or pressure is used
against or in concert with any officer or employee of the City in connection with the award,
terms or implementation of this Agreement, including any method of coercion, confidential
financial arrangement, or financial inducement. No officer or employee of the City will
receive compensation, directly or indirectly from Contractor, or any officer, employee or
agent of Contractor, in connection with the award of this Agreement or any work to be

breach of this Agreement entitling the City to any and all remedies at law or in equity.
16.NO BENEFIT TO ARISE TO LOCAL EMPLOYEES
No member, officer, or employee of the City, or their designees or agents, and no
public official who exercises authority over or responsibilities with respect to the Services

indirect, in any agreement or sub-agreement, or the proceeds thereof, for work to be
performed in connection with the Services performed under this Agreement.
17.CONFLICT OF INTEREST
Contractor covenants that neither they nor any officer or principal of their firm have
any interests, nor shall they acquire any interest, directly or indirectly, which will conflict
in any manner or degree with the performance of their services hereunder. Contractor
further covenants that in the performance of this Agreement, they shall employ no person
having such interest as an officer, employee, agent, or subcontractor. Contractor further

EXHIBIT A
INSURANCE REQUIREMENTS
Prior to the beginning of and throughout the duration of Work, Contractor will maintain
insurance in conformance with the requirements set forth below. Contractor will use
existing coverage to comply with these requirements. If that existing coverage does not
meet requirements set forth here, Contractor agrees to amend, supplement or endorse
the existing coverage to do so. Contractor acknowledges that the insurance coverage
and policy limits set forth in this section constitute the minimum amount of coverage
required. Any insurance proceeds available to the City in excess of the limits and
coverage required in this Agreement and which is applicable to a given loss, will be
available to the City.
Contractor shall provide the following types and amounts of insurance:
Commercial General Liability Insurance using Insurance Services Office (ISO)
“Commercial General Liability” policy form CG 00 01 or the exact equivalent. Defense
costs must be paid in addition to limits. There shall be no cross liability exclusion for claims
or suits by one insured against another. Limits are subject to review but in no event less
than $1,000,000 per occurrence for all covered losses and no less than $2,000,000
general aggregate.
Business Auto Coverage on ISO Business Auto Coverage form CA 00 01 including
symbol 1 (Any Auto) or the exact equivalent. Limits are subject to review, but in no event
to be less than $1,000,000 per accident. If Contractor owns no vehicles, this requirement
may be satisfied by a non-owned auto endorsement to the general liability policy
described above. If Contractor or Contractor’s employees will use personal autos in any
way on this project, Contractor shall provide evidence of personal auto liability for each
such person.
Workers’ Compensation on a state-approved policy form providing statutory benefits as
required by law with employer’s liability limits no less than $1,000,000 per accident or
disease.
Excess or Umbrella Liability Insurance (Over Primary) if used to meet limit requirements,
shall provide coverage at least as broad as specified for the underlying coverages.
Coverage shall be provided on a “pay on behalf” basis, with defense costs payable in
addition to policy limits. Policy shall contain a provision obligating insurer at the time
insured’s liability is determined, not requiring actual payment by the insured first. There
shall be no cross liability exclusion precluding coverage for claims or suits by one insured
against another. Coverage shall be applicable to the City for injury to employees of
Contractor, subcontractors or others involved in the Work. The scope of coverage
provided is subject to approval by the City following receipt of proof of insurance as
required herein. Limits are subject to review.
441
West Coast Arborists, Inc. Page 12 of 48
Insurance procured pursuant to these requirements shall be written by insurers that are
admitted carriers in the State of California and with an A.M. Bests rating of A- or better
and a minimum financial size of VII.
General conditions pertaining to provision of insurance coverage by Contractor.
Contractor and the City agree to the following with respect to insurance provided by
Contractor:
1. Contractor agrees to have its insurer endorse the third party general liability
coverage required herein to include as additional insureds the City, its officials,
employees, and agents, using standard ISO endorsement CG 2010 and CG 2037
with edition acceptable to the City. Contractor also agrees to require all contractors
and subcontractors to do likewise.
2. No liability insurance coverage provided to comply with this Agreement shall
prohibit Contractor, or Contractor’s employees, or agents, from waiving the right to
subrogation prior to a loss. Contractor agrees to waive subrogation rights against
the City regardless of the applicability of any insurance proceeds, and to require
all contractors and subcontractors to do likewise.
3. All insurance coverage and limits provided by Contractor and available or
applicable to this Agreement are intended to apply to the full extent of the policies.
Nothing contained in this Agreement or any other agreement relating to the City or
its operation limits the application of such insurance coverage.
4. None of the coverages required herein will be in compliance with these
requirements if they include limiting endorsement of any kind that has not been
first submitted to the City and approved in writing.
5. No liability policy shall contain any provision or definition that would serve to
eliminate so-called “third party action over” claims, including any exclusion for
bodily injury to an employee of the insured or of any contractor or subcontractor.
6. All coverage types and limits required are subject to approval, modification, and
additional requirements by the City, as the need arises. Contractor shall not make
any reductions in scope of coverage (e.g. elimination of contractual liability or
reduction of discovery period) that may affect the City’s protection without the
City’s prior written consent.
7. Proof of compliance with these insurance requirements, consisting of certificates
of insurance evidencing all of the coverages required and an additional insured
endorsement to Contractor’s general liability policy, shall be delivered to city at or
prior to the execution of this Agreement. In the event such proof of any insurance
is not delivered as required, or in the event such insurance is canceled or reduced
at any time and no replacement coverage is provided, the City has the right, but
not the duty, to obtain any insurance it deems necessary to protect its interests
under this or any other Agreement and to pay the premium. Any premium so paid
442
West Coast Arborists, Inc. Page 13 of 48
by the City shall be charged to and promptly paid by Contractor or deducted from
sums due Contractor, at the City’s option.
8.Certificate(s) are to reflect that the insurer will provide 30 days notice to the City of
any cancellation or reduction of coverage. Contractor agrees to require its insurer
to modify such certificates to delete any exculpatory wording stating that failure of
the insurer to mail written notice of cancellation or reduction of coverage imposes
no obligation, or that any party will “endeavor” (as opposed to being required) to
comply with the requirements of the certificate.
9.It is acknowledged by the parties of this Agreement that all insurance coverage
required to be provided by Contractor or any subcontractor, is intended to apply
first and on a primary, non-contributing basis in relation to any other insurance or
self-insurance available to the City.
10.Contractor agrees to ensure that subcontractors, and any other party involved with
the Work who is brought onto or involved in the Work by Contractor, provide the
same minimum insurance required of Contractor. Contractor agrees to monitor and
review all such coverage and assumes all responsibility for ensuring that such
coverage is provided in conformity with the requirements of this section. Contractor
agrees that upon request, all agreements with subcontractors and others engaged
in the Work will be submitted to the City for review.
11.Contractor agrees not to self-insure or to use any self-insured retentions or
deductibles on any portion of the insurance required herein and further agrees that
it will not allow any contractor, subcontractor, Architect, Engineer, or other entity
or person in any way involved in the performance of Work contemplated by this
Agreement to self-insure its obligations to the City. If Contractor’s existing
coverage includes a deductible or self-insured retention, the deductible or self-
insured retention must be declared to the City. At that time, the City shall review
options with the Contractor, which may include reduction or elimination of the
deductible or self-insured retention, substitution of other coverage, or other
solutions.
12.The City reserves the right at any time during the term of the Agreement to change
the amounts and types of insurance required by giving the Contractor 90 days
advance written notice of such change. If such change results in substantial
additional cost to the Contractor, the City will negotiate additional compensation
proportional to the increased benefit to the City.
13.For purposes of applying insurance coverage only, this Agreement will be deemed
to have been executed immediately upon any party hereto taking any steps that
can be deemed to be in furtherance of or towards performance of this Agreement.
14.Contractor acknowledges and agrees that any actual or alleged failure on the part
of the City to inform Contractor of non-compliance with an insurance requirement
in no way imposes any additional obligations to the City nor does it waive any rights
hereunder in this or any other regard.
443
West Coast Arborists, Inc. Page 14 of 48
15. Contractor will renew the required coverage annually as long as the City, or its
employees or agents face an exposure from operations of any type pursuant to
this Agreement. This obligation applies whether or not the Agreement is canceled
or terminated for any reason. Termination of this obligation is not effective until the
City executes a written statement to that effect.
16. Contractor shall provide proof that policies of insurance required herein expiring
during the term of this Agreement have been renewed or replaced with other
policies providing at least the same coverage. Proof that such coverage has been
ordered shall be submitted prior to expiration. A coverage binder or letter from
Contractor’s insurance agent to this effect is acceptable. A certificate of insurance
and/or additional insured endorsement as required in these specification
applicable to the renewing or new coverage must be provided to the City within
five days of the expiration of coverage.
17. The provisions of any Workers’ Compensation or similar act will not limit the
obligations of Contractor under this Agreement. Contractor expressly agrees not
to use any statutory immunity defenses under such laws with respect to the City,
its employees, officials, and agents.
18. Requirements of specific coverage features or limits contained in this section are
not intended as limitations on coverage, limits, or other requirements nor as a
waiver of any coverage normally provided by any given policy. Specific reference
to a given coverage feature is for purposes of clarification only as it pertains to a
given issue, and is not intended by any party or insured to be limiting or all-
inclusive.
19. These insurance requirements are intended to be separate and distinct from any
other provision in this Agreement and are intended by the parties here to be
interpreted as such.
20. The requirements in this section supersede all other sections and provisions of this
Agreement to the extent that any other section or provision conflicts or impairs the
provisions of this section.
21. Contractor agrees to be responsible for ensuring that no contract used by any party
involved in any way with the Work reserves the right to charge the City or
Contractor for the cost of additional insurance coverage required by this
Agreement. Any such provisions are to be deleted with reference to the City. It is
not the intent of the City to reimburse any third party for the cost of complying with
these requirements. There shall be no recourse against the City for payment of
premiums or other amounts with respect thereto.
22. Contractor agrees to provide immediate notice to City of any claim or loss against
Contractor arising out of the work performed under this Agreement. The City
assumes no obligation or liability by such notice, but has the right (but not the duty)
444
West Coast Arborists, Inc. Page 15 of 48
to monitor the handling of any such claim or claims if they are likely to involve the
City.
23. Contractor agrees to obtain and provide to City a copy of Professional Liability
coverage for Architects or Engineers on this project, when required by City. City
shall determine the liability limit.
445

e. Hazardous trees of any species may be pruned any time of the year
for abatement reasons.
458
West Coast Arborists, Inc. Page 29 of 48
5.Pruning Distressed City Trees
Contractor shall avoid additional injury to distressed trees
a.If a City tree has been damaged by injury or disturbance, pruning
shall be delayed until deadwood becomes evident. Crown cleaning
is then recommended.
b.City trees that have received little or no care or maintenance may
need moderate crown thinning, reduction of end weights, or entire
crown restoration.
6.Pruning Young City Trees
Contractor shall prune young City trees during the second year after
planting to improve their structure, and only minor crown cleaning every
three to seven years thereafter. Branches shall be spaced at least 18
inches apart to alleviate tight grouping branches.
7.Wildlife Avoidance / Migratory Bird Treaty Act Compliance
Contractor shall determine the optimal time to prune when considering the
health interests of the trees and when trying to avoid bird nests. Contractor
shall follow all State and federal regulations prohibit the disturbance and
destruction of many active bird nests.
8.Insect and Disease Control
Contractor shall report any insects or disease may lead to the death of a
City tree.
9.Woodchips or Mulch
Contractor generated woodchips or mulch from trimming operations within
the City shall be removed and disposed by contractor. Woodchips may be
dumped and spread at a City designated site upon specific permission from
the City Representative.
Contractor shall provide and submit estimated tonnage of woodchips
generated annually (January to December) to the City Representative.
10.Milling Urban Lumber
At the direction of the City’s Representative, large tree trunks, which meet
proper specifications, may be required to be milled into lumber suitable for
use in a variety of applications. Milled lumber shall be returned to the City.
Rates for milling services are to be determined by the City and Contractor
in writing on a case by case basis.
B.GRID TREE PRUNING: Any tree work performed on a City tree must be done
according to the City's specifications. The criterion for pruning varies based on the
type or purpose of pruning.
1.General Specifications for tree pruning.
459
West Coast Arborists, Inc. Page 30 of 48
a. Contractor shall consult with the City Representative before making
any cuts that could result in permanent disfigurement of the structure
of any tree
b. City trees shall be pruned so as to prevent branch and foliage
interference with safe public passage. Street clearance shall be kept
to a minimum of fourteen feet, six inches (14' 6") above the paved
surface of the street and fourteen (14) feet above the curb and
surface of a public sidewalk or pedestrian way. Exceptions are
allowed for young trees, which would be irreparably damaged by
such pruning action. If pruning to these standards would result in
permanent disfiguration of a tree, the Contractor shall not prune the
tree until such time as direction is obtained from the City
Representative.
c. When removing a live branch, pruning cuts should be made in branch
tissue just outside the branch bark ridge and collar, which are trunk
tissue. If no collar is visible, the angle of the cut should approximate
the angle formed by the branch bark ridge and the trunk.
d. When removing a dead branch, the final cut should be made outside
the collar of live callus tissue. If the collar has grown out along the
branch stub, only the dead stub should be removed, the live collar
should remain intact and uninjured.
e. Whenever pruning involves the removal of limbs that are too large to
hold securely in one hand during the cutting operation, the limb shall
be cut off first at a point several feet beyond the intended final cut.
The final cut shall be made in a manner to prevent unnecessary
tearing back of the bark and wood. Cuts that result in tearing of tissue
on limbs below cuts shall be corrected, and shall not exceed ½ inch
from the hardscape surface being edged.
f. All final tree pruning cuts shall be made in such a manner so as to
favor the earliest possible covering of the wound by natural callus
growth. Excessively deep flush cuts, which produce large wounds or
weaken the tree at the cut, shall not be made. The branch collar
should not be removed.
g. All dead and dying branches and branch stubs shall be removed.
h. All broken or loose branches shall be removed.
i. Branches that are developing in such a manner as to become larger
than the limbs they originate from shall be removed.
j. When encountering limbs that are weighted with more foliage than
the limb is likely to support, selectively prune branches toward the
end of the limb in order to reduce
k. Selectively prune branches that create sight line conflicts with traffic
control signs and/or devices.
460
West Coast Arborists, Inc. Page 31 of 48
l.Selectively prune branches that are within five (5) feet of a structure.
m.Clear trees of sprout or sucker growth to a minimum height of ten
(10) feet above ground level. Exceptions are allowed for young trees,
which would be irreparably damaged by such pruning action.
n.Prune so as to maintain a balanced appearance when viewed from
the opposite side of the street immediately opposite the tree, unless
authorized by the City Representative to do otherwise.
o.Remove all vines entwined in trees and on tree trunks. Vine tendrils
shall be removed without injury to trees.
p.Tree limbs shall be removed and controlled in such a manner as to
cause no damage to other parts of the tree, or to other plants or
property.
q.All tools used on a tree known to contain an infectious tree disease
shall be properly disinfected immediately before and after completing
work on such tree.
r.All major pest problems shall be promptly reported to the City.
s.All cutting tools and saws used in tree pruning shall be kept
sharpened to result in final cuts with an un-abrasive wood surface
and secure bark remaining intact.
t.All trees six (6) inches in diameter or less shall be pruned with hand
tools only.
u.Chain saws will not be permitted to remove any branches two (2)
inches or less in diameter. This is to prevent any unnecessary
abrasions to cambial tissue that may predispose a tree to insect
and/or future disease/decay problems.
v.Any extraneous metal, wire, rubber or other material interfering with
tree growth shall be removed when possible.
w.The use of climbing spurs or spike shoes in the act of pruning trees
is prohibited, unless specifically directed by the City to aid in the
safety of climbers performing the removal of a tree.
2.Prune Classifications for City Trees
a.Full Prune: Full Prune is performed when conditions within the crown
of a hardwood tree are such that the entire tree needs to be fully
pruned. Complete pruning is recommended when the primary
objective is to maintain or improve tree health and structure, and
includes pruning to reduce overall canopy mass and excessive wood
weight. Trees that are identified for a Full Prune shall have no more
461
West Coast Arborists, Inc. Page 32 of 48
than 30% of the live foliage removed. A Full Prune typically consists
of one or more of the following pruning treatments:
1) Crown Cleaning: Crown Cleaning or cleaning out is the removal
of dead, diseased, crowded, weakly attached and low-vigor
branches and water sprouts from the entirety of the tree crown.
Care must be used to avoid stripping branches of all foliage at the
interior of the tree crown. This practice, known as "lion tailing"
disrupts the structural integrity of the tree, making it subject to
limb and branch failure, especially during high winds.
2) Crown Thinning: Crown Thinning includes crown cleaning and
the selective removal of branches to increase light penetration
and air movement into and through the crown. Increased light and
air stimulates and maintains interior foliage, which in turn
improves branch taper and strength. Thinning reduces the wind-
sail effect of the crown and the weight of heavy limbs. Care must
be used to avoid stripping branches of all foliage at the interior of
the tree crown. Thinning the crown can emphasize the structural
beauty of trunk and branches as well as improve the growth of
plants beneath the tree by increasing light penetration. When
thinning the crown of mature trees, up to 30% of the live foliage
may be removed unless directed otherwise by the City
Representative.
3) Crown Reduction: Crown Reduction is used to reduce the height
and/or spread of a tree. Crown reduction varies from topping, a
destructive practice, in that cuts are not made indiscriminately,
resulting in large stubbed off limbs that are subject to decay.
While reducing a crown, tree workers must adhere to basic tree
trimming practices involving limb/branch size relationships and
use of the branch bark collar in avoiding the onset of decay at cut
sites.
4) Crown Restoration: Crown Restoration is corrective pruning used
as a means to restore the form of crowns that have been
previously damaged by extenuating circumstances. This
treatment is best performed by tree workers who have a good
understanding of the effects of pruning for the cultivation of tree
canopies.
b. Crown Raising/Clearance Prune: A Crown Raising or Clearance
Prune is performed when conditions within the crown of a hardwood
tree are such that a certain objective needs to be met or a certain
condition needs attention. A crown raising or clearance prune does
not involve the detail of work found in a full prune. Crown raising or
clearance pruning may consist of one or more of the following
pruning types:
462
West Coast Arborists, Inc. Page 33 of 48
1) Crown Raising: Crown Raising consists of removing the lower
branches of a tree in order to provide clearance for buildings,
vehicles and pedestrians. It is important that a tree have at least
one-half of its foliage on branches that originate in the lower two-
thirds of its crown to ensure a well-formed, tapered structure and
to uniformly distribute stress within the tree.
2) Clearance Prune: Clearance Prune is employed as a means of
eliminating limbs from the crown of a hardwood tree when an
entire pruning of the tree is not warranted. Clearance pruning
does not involve the fine detail work described herein as "full
prune".
3. Pruning Specifications for Individual Species
a. General Trimming and Shaping of Conifers: Two basic classes of
conifers can be found in Moorpark, those with branches radiating out
from the trunk in whorls such as Pine trees or Cedar trees and those
that sprout branches in a random manner such as Juniper or Taxus.
Conifers shall typically be pruned in late winter or early spring.
Typically, up to 30% of the live foliage may be removed unless
directed otherwise by the City Representative.
b. Contractor shall avoid damaging the central leader on all conifers. In
specific cases the City Representative may direct the contractor to
remove the central leader in an effort to limit the height of specific
trees.
c. At the time of pruning, the City Representative shall determine which
trees shall have the new growth pinched back in an effort to control
canopy size.
d. To control the growth of large, mature conifers contractor shall be
required to prune the new growth of lateral limbs.
e. Typical pruning of conifers shall consist of removing crossed limbs,
deadwood or unwanted branches from the interior of the canopy.
f. General Trimming and Shaping of Broadleaf Trees: Follow the shape
indicated by the natural growth habits of each tree species. Trimming
and shaping of trees shall be as directed by the City Representative
and in accordance with the following:
• Cut to laterals to preserve the natural form of the tree leaving the
head open enough for the branching system to show and
permitting the dead material to be easily cleaned out and to allow
light to show through the head. Tree foliage shall be reduced by
at least twenty-five percent (25%) and up to thirty percent (30%).
• In specific cases the City Representative may direct the
contractor to reduce the size of the tree crown in an effort to limit
the height of specific trees.
463
West Coast Arborists, Inc. Page 34 of 48
•Trim to remove dead wood or weak diseased, insect-infested,
broken, low, or crossing limbs. Branches with an extremely
narrow angle of attachment should normally be removed.
•Small limbs, including suckers and waterspouts, shall be cut
close to the trunk or branch from which they arise.
•Heading cuts and/or topping will not be allowed under any
circumstances. Heading, rounding over, or stubbing shall not be
an accepted practice for reducing the size or the framework of
any tree.
C.PEPPER TREE MAINTENANCE SERVICES: (Historical High Street)
Historical High Street population of fifty (50) California Pepper (Schinus molle)

D. PALM TREE PRUNING:
Any tree work performed on a City tree must be done according to the City’s
specification. The criterion for pruning varies based on the type or purpose of
pruning. Palm Pruning consists of maintaining the crowns and trunks of palm trees
including the pruning of spent or declining fronds, seedpods and the skinning or
shaping of spent petiole bases into a ball or nut as applicable by palm type.
1. The specifications for the pruning of palm trees are as follows:
a. While making an approach to the palm crown for pruning, the
Contractor shall inspect the trunk of the palm tree for signs of decay,
466
West Coast Arborists, Inc. Page 37 of 48
insect frass, bird nesting or any other condition suggestive of a
structural abnormality. Upon finding any condition suggestive of a
structural abnormality of the palm stem, the Contractor shall report
to the City Arborist immediately.
b.Fronds shall be pruned using a chainsaw, handsaw or pole saw that
has been sterilized by having the entirety of its cutting blade
submersed in an equal solution of bleach and water before and after
the handsaw is used to cut the fronds of any other palm tree.
c.At no time shall a chainsaw be used to prune any frond from any
Canary Island Date Palm (Phoenix canariensis). A separate
handsaw shall be used for each Canary Island Date Palm (Phoenix
canariensis).
d.Live, healthy fronds, initiating at an angle of 90 degrees or greater
from the horizontal plane, shall not be removed. Fronds removed
should be cut close to the petiole base, taking into consideration the
role of petiole bases in the formation and maintenance of the
ornamental ball at the base of the canopy, as applicable by species.
Live trunk tissue should not be cut while pruning palm fronds.
e.Using properly sterilized equipment as described herein, any fruit or
flower structures in the crown of the palm shall be removed
concurrently with frond pruning. At no time shall a chainsaw be used
to cut any fruit or flower from any Canary Island Date Palm (Phoenix
canariensis).
f.Care shall be taken in the handling of fruit and flowers, as they are
likely to release clear liquids that react with and can cause staining
to hardscape elements.
g.Maintenance of the ornamental ball located at the base of the palm
canopy, directly below the live fronds, shall be as described by
species as follows:
Canary Island Date Palm (Phoenix canariensis): At the City’s
direction and as an added cost, the Contractor may be directed to
form the dead petiole bases into an ornamental ball, which begins
directly below the lowest green fronds and acts to provide a base of
support to the palm crown. This ornamental ball shall be uniform and
smooth in appearance and shall extend no less than four (4) and no
more than eight (8) feet below the lowest live frond in the crown.
Ornamental balls with flattened or “stop sign” sides will not be
accepted. The upper portion of the ornamental ball shall not taper in,
resulting in a “pineapple” appearance as this treatment defeats the
support capacity of the ball. The distal portion of the ball shall begin
at a point flush with the periphery of the palm trunk and make a
gradual taper upwards until it reaches the periphery of the shaped
ornamental ball. While forbidden to use chainsaws for pruning
467
West Coast Arborists, Inc. Page 38 of 48
fronds, fruit and flowers from any palm tree, the Contractor may use
a clean chainsaw in forming and/or shaping the ornamental ball of a
Canary Island Date Palm. The use of a sharpened shovels in shaping
and maintaining ornamental balls often results in ornamental balls
which have flat, untapered bottoms that are likely to relax and
collapse into pedestrian and vehicular traffic zones with grave
consequences.
Date Palm (Phoenix dactylifera): At the City’s direction and as an
added cost, the Contractor may be directed to shape the the base of
the Date Palm. Spent petiole bases are left to form a supportive
“base” below the lowest green fronds of the crown. Unlike the
ornamental ball of a Canary Island Date Palm (Phoenix canariensis),
the base does not require ornate shaping. Instead, spent petiole
bases are left uniformly long to form the base of the canopy, which
shall extend no less than four (4) and no more than six (6) feet below
the lowest live frond in the crown. While forbidden to use chainsaws
for pruning fronds, fruit and flowers from any palm tree, the
Contractor may use a chainsaw in forming and/or shaping the base
of a Date Palm by shortening a number of the lower petiole bases to
bring the length of the nut to standard. The Contractor shall use care
not to cut into live trunk tissue while maintaining the nut. The
Contractor shall verify that the base meets the standard described
herein each time a Date Palm is pruned.
Queen Palm (Syagrus romanzoffianum): loose petiole bases are to
be removed each time the crown of a Queen Palm is serviced.
Petiole bases that are attached to live trunk tissue shall be left
undamaged.
King Palm (Archontophoenix cunninghamiana): loose petiole bases
are to be removed each time the crown of a King Palm is serviced.
Petiole bases that are attached to live trunk tissue shall be left
undamaged.
Mexican Fan Palm (Washingtonia robusta): spent petiole bases are
left uniformly long to form a base, which shall extend no more than
four (4) feet below the lowest live frond in the crown. At the City’s
direction and as an added cost, the Contractor may be directed to
skin the trunk area below the base clean without causing damage to
live trunk tissue. The Contractor shall verify that the base meets the
standard described herein each time a Mexican Fan Palm is pruned.
California Fan Palm (Washingtonia filifera): spent petiole bases are
left uniformly long to form a nut, which shall extend no more than
eight (8) feet below the lowest live frond in the crown. At the City’s
direction and as an added cost, the Contractor may be directed to
skin the trunk area below the base clean without causing damage to
live trunk tissue. The Contractor shall verify that the base meets the
468
West Coast Arborists, Inc. Page 39 of 48
standard described herein each time a California Fan Palm is
pruned.
