SUBJECT: NOTICE OF VIOLATION DRC2010-00630 — REMOVAL AND TOPPING OF HERITAGE
. TREES WITHOUT A PERMIT, LOCATED AT 9944 HIGHLAND AVENUE
Pastor Watkin:
It has recently been brought to the City's attention that approximately 38 Eucalyptus and Sycamore trees
have been removed or topped on the subject property without a valid Tree Removal Permit, which is a
violation of Section 19.08.050 of the City of Rancho Cucamonga Municipal Code.
Planning Department staff previously met with you and other members of Highland Avenue Community
Church and adjacent neighbors on June 17, 2010, to discuss ongoing issues with the existing trees. Both the
church and the adjacent neighbors expressed concerns about on -going maintenance and damage to the
property because of excessive leaf litter.
Staff understood these concerns and advised the church that they could submit an application for a Tree
Removal Permit with a supporting arborist report, identifying the number of trees proposed to be removed and
the justification for said removal. Staff further noted that while the removal of trees may be considered by the
Planning Commission, replacement of certain quantities and types in conformance with Municipal Code
Section 19.08.100 and other Development Code sections would still apply.
Following the meeting, staff provided copies of the Tree Removal Permit application as well as applicable
Code sections. Staff indicated that they were available to provide any support as needed in the preparation
and submittal of the applications. On August 17, 2010, a follow-up site inspection was conducted by the
Code Enforcement Department staff, which noted the removal of three (3) trees and the forty-six (46)
toppings of trees even though a Tree Removal Permit was not applied for.
Please note that the intended killing/removal of trees (without a permit) constitutes a violation of Section
19.08.050 of the Municipal Code, which constitutes a misdemeanor, punishable by a fine of not more than
one thousand dollars or by imprisonment not to exceed six months, or both such fine and imprisonment:
Each tree removed in violation of this Chapter shall constitute a separate offense (Section 19.08.130).

The City of Rancho Cucamonga is willing to work with property owners in order to comply with the City's Tree
Preservation Ordinance, and respectfully requests that the property owner submit a Tree Removal Permit
.application with supporting arborist letter as previously discussed, or a Maintenance/Replacement Planting
Program to be reviewed and approved by the Planning Department by October 1, 2010. Should a Tree
Removal Permit application not be received by this date, the City reserves the right to pursue any or all
penalties as described in Section 19.08.130 of the Municipal Code. Staff has attached.a copy of the Tree
Removal Permit application with this letter.
Please note the Church facility was permitted with a Conditional Use Permit (No. 83-02), which required
specific landscaping requirements (see attached copy of the Resolution of Approval by the Planning
Commission). It appears that the actions to the trees may be considered a violation of the Conditional Use
Permit Planning Department Conditions 1, 2, and 3, as well as Standard Condition Landscaping No..8, of the
attached Resolution. Unless this matter is successfully resolved, the existing Conditional Use Permit may be
referred to the Planning Commission for review.
On August 19, 2010, Mr. Henderson, Principal Planner, spoke with you on the phone. It was stated that the
topping of the trees was intended for trimming purposes. Please note that topping is not considered an
acceptable trimming procedure since it can weaken and kill the tree. Also, if the tree survives, the new
branches are susceptible to breaking off and falling, potentially causing damage. See attached information
on the matter of topping trees.
Should you have any questions regarding the application or submittal requirements, please do not hesitate to
contact the project planner, Larry Henderson, Principal Planer, at (909) 477-2750, Monday through Thursday,
between the hours 7:00 a.m. to 6:00 p.m.

3.0 Tree Maintenance Guidelines
Introduction
Trees are a major element of city parks and Department staff should continue to learn
more about tree care in order to prolong the health of all trees. All DRP Divisions
should perceive the cost of tree maintenance as an investment in its capital assets.. It is
the intention of the following sections to provide guidelines to maintenance practices
that result in the best environment for park trees.
3.10 Care of trees listed in the DRP Tree Preservation Policy
Pruning performed on park trees adheres to the latest standards and recommendations
made available by industry professionals and the International Society of Arboriculture
(ISA). In the following sections watering, fertilizing, and general maintenance practices
will be discussed. Work performed to trees protected by the L.A. City Ordinance, as
well as Heritage Trees and Special Habitat Value Trees, must always adhere to these
recommendations.
For trees protected by the L.A. City Ordinance, a permit must be obtained from the
Board of Public Works to perform any alteration to the tree or pruning of any branches
larger than 2 inches in diameter. Permitted pruning shall be done in compliance with
the Oak Tree Pruning Standards set forth by the Western Chapter of the International
Society of Arboriculture.
Trees recognized as DRP Heritage Trees and Special Habitat Value Trees can be
pruned with the approval of the DRP Forestry staff. Pruning shall be done in
accordance with the Oak Tree Pruning Standards set forth by the Western Chapter of
the International Society of Arboriculture. Any work within the tree's dripline also
requires approval from DRP Forestry staff.
Park trees recognized as Common Park Trees are to be protected by applying the most
current ANSI (American National Standards Institute) and ISA recommendations for tree
pruning, as well as maintenance practices as described in the following sections.
3.15 Request for Tree Work Guidelines
To date, the Department has not established a pruning cycle, and tree care performed
by the Forestry Division is by demand only. Field staff shall call the Forestry office at
(213) 485-4826 any time tree pruning or inspection is required. Trees by nature shed
bark and drop leaves, fruits, seeds, and small branches. In many instances, the
Forestry crew will not be able to solve tree litter problems by pruning. It is important for
field staff to evaluate tree pruning needs before calling in the work order. Misleading
information and calling regular tree pruning needs as emergency requests results in
inefficient use of the Forestry crews. Below is a guideline of regular job order requests
and emergency requests for tree work.
TREE CARE MANUAL/Tree Maintenance Guidelines Page 1 of 15
3.15.1 Regular Work Order Requests:
Regular work order requests are for all tree maintenance that does not fall under the
Tree Emergencies category. These types of requests include pruning of trees not
posing an immediate hazard to human life or property or for large-scale projects (for
example, trees blocking light fixtures, signs, or impeding walkway/road clearance), and
require a work order submitted to the Forestry Division. The Lead Sr. Gardener, Park
Maintenance Supervisor, or Sr. Park Maintenance Supervisor must call in all work order
requests. Work orders will be reviewed and prioritized by the respective Principal Park
Maintenance Supervisors.
3.15.2 Tree emergencies:
The following is a list of possible tree emergencies in priority order:
High Priority:
1. Trees or limbs that have fallen and caused accidents or personal injury
2. Trees or limbs that have fallen and caused damage to vehicles or structures
3. Trees or limbs which are in immediate danger of falling or breaking
4. Broken hanging limbs adjacent to structures, roads, or in picnic or play areas,
play areas
5. Trees or limbs that blocking streets or roads
Medium to Low Priority:
1. Trees or limbs that have fallen and are not an immediate hazard
2. Trees or limbs that have fallen and are not blocking roads or streets
3- Hanging tree limbs that may not be in immediate danger of falling
4. Dead or severely declining trees without a target present
3.20 DRP Pruning Standards
Pruning means the removal of leaves or dead parts of plants, especially branches, to
achieve the following:
■ maintain or direct plant form
■ enhance health and appearance
■ influence flowering, fruiting, and vigor
■ regulate growth
■ control plant size
■ invigorate declining plants
Trees and other woody plants respond biologically to pruning (wounding) in specific and
predictable ways. Careful study of these responses has lead to pruning practices that
can best develop, preserve, and enhance the structural integrity, beauty and functional
value of trees.
TREE CARE MANUAL/Tree Maintenance Guidelines Page 2 of 15
3.20.1 Industry Standards
The ANSI A300-2001-Pruning presents performance standards for the care and
maintenance of trees, shrubs, and other woody plants (Appendix C).
Best Management Practices — Tree Pruning is the companion publication to the ANSI
A300-2001 (Appendix D)
3.20.2 Types of Pruning
The DRP uses seven types of pruning: structural, crown cleaning, thinning, raising,
reducing, restorative, and pruning of palms and conifers.
Climbing spikes shall not be used to climb park trees or palms for the purpose of
pruning. Climbing spikes may be used to rescue an injured worker or remove dead,
dying, or hazardous trees.
The DRP Forestry staff evaluates trees from the ground before determining the type of
pruning by referring to the Tree Operations Manual.
Considerations are based on tree species and can include the following:
■ Species growth characteristics
■ Time of year
■ Tree form (ex: excurrent or decurrent)
■ Tree condition (health)
■ Tree structure —presence of weaknesses or defects
Staff determines from the ground what limbs need to be removed to achieve or enhance
a tree's structural integrity, appearance, or desired size.
➢ Pruning for Structure
Structural pruning is the removal of live branches and stems to influence structural
integrity. It usually follows four procedures: 1) Canopy cleaning by removing dead,
broken, diseased and dying branches, 2) development or re-establishment of a
dominant leader, 3) establishment of the lowest permanent scaffold limb and 4)
establishment of scaffold limbs by removing competing stems or branches.
➢ Pruning to Clean
Cleaning is the selective removal of dead, diseased, detached, rubbing and broken
branches. This type of pruning is done to reduce the risk of branch failure and the
transmission of decay, insects and diseases.
➢ Pruning to Thin
Thinning is the selective removal of small live branches to reduce crown density.
Branches are % to 1-inch in diameter. 10-15 percent of live foliage can be removed
at one time. If more pruning is desired, it should not exceed 25 percent in a single
year. Excessive removal of small branches on the lower two-thirds of a branch or
stem is called lion tailing and may have an adverse effect on the tree — it is not an
accepted practice.
TREE CARE MANUAL/Tree Maintenance Guidelines Page 3 of 15
➢ Pruning to Raise
Raising is the selective removal of branches to provide vertical clearance. Caution
must be taken to not remove too many lower branches. This can cause slow
development of trunk taper, cause cracks or decay in the trunk, or transfer too much
weight to the top of the tree.
➢ Pruning to Reduce (Drop Crotch)
Reduction is the selective removal of branches and stems to decrease the height
and/or spread of a tree. This type of pruning is done to minimize the risk of failure,
to reduce height or spread, for utility clearance, to clear vegetation from buildings or
other structures, or to improve tree appearance. Crown reduction shall be
accomplished with reduction cuts rather then heading cuts.
➢ Pruning to Restore
Restoration is the selective removal of branches, sprouts, and stubs from trees that
have been topped, severely headed, vandalized, lion -tailed, broken during a storm,
or otherwise damaged. Full restoration usually requires several pruning events over
a numberof years.
➢ Pruning Palms
Palm pruning primarily removes dead and chlorotic fronds. Green fronds growing at
an angle of more than 45 degrees from horizontal shall be retained. DRP Forestry
staff minimizes the risk of disease transmission by pruning green fronds of
Washingtonia and Phoenix species with handsaws disinfected in 1 % bleach solution
after each tree is pruned.
➢ Pruning Conifers
Conifers are primarily pruned to control the density of branching, the shape of young
trees, and the size of older ones. They are intolerant of topping or heading. Conifers
typically have an excurrent growth habit, which is usually maintained throughout the
lifespan of the tree. The DRP strives to prune conifers outside of hot summer
months when the infestation of the bark beetles is more likely to occur. Thinning, by
the selective removal of small branches, is the most appropriate method when
pruning conifers.
3.20.3 Pruning Cuts
A proper pruning cut causes very little injury to the adjoining stem. When the pruning cut
is properly made a ring of woundwood forms above and below the wound during the
first growing season after the cut. Pruning cuts are not covered with wound dressings
or sealants. DRP Forestry staff sometimes applies a light coating of a nonphytotoxic
material for aesthetical purpose. The DRP typically uses two types of cuts: `Branch
Removal Cut' (thinning cut) and `Reduction Cut' (drop -crotch cut). Flush cuts, those
made "flush" with the parent stem, removes chemical barriers that counter decay and is
no longer an accepted practice.

The first cut (A) undercuts the limb. The second cut (B) removes the limb. The
final cut (C) should be just outside the branch collar to remove the resulting
stub. A pruning cut that removes a branch at its point of origin shall be made
close to the trunk or parent limb, without cutting into the branch bark ridge or
collar, or leaving a stub. Branches too large to support with one hand shall be
precut to avoid splitting of the wood or tearing of the bark.

TREE CARE MANUAL/Tree Maintenance Guidelines Page 6 of 15
3.20.4 Timing of Pruning
Hazardous trees of any species may be pruned any time of the year. Removal of dying,
diseased, broken, rubbing, or dead limbs can also be accomplished at any time with
little negative effect on the tree. Light pruning (removing less than 10 percent of the
foliage) can be performed safely on most species at any time providing the trees are in
good health.
Plant development can be slowed and plant size maintained if pruning takes place soon
after growth is complete for the season. Such pruning should not be so severe or so
early as to encourage new shoot growth. If maximum dwarfing is desired, most plants
should be pruned in the period from early to midsummer. This will reduce leaf area for
the longest period.
Most deciduous plants can be pruned during the dormant period between leaf fall to the
end of winter with similar growth results. Avoid pruning broadleaf trees in early to late
spring. Evergreens will be set back the least if they are pruned in the late winter. This
also minimizes bark beetle attack on conifers.
Pruning when trees are dormant can minimize the risk of pest problems associated with
wounding (attracting insects to fresh wounds), and can allow trees to take advantage of
the full growing season to close and compartmentalize wounds. Avoid pruning trees,
and especially stressed trees during or soon after the initial growth flush in spring. This
is when the cambium is active and bark is particularly vulnerable to being torn loose.
Corrective pruning may be easier during the growing season. Branches that hang too
low from the weight of leaves or fruit can be thinned and dead and weak limbs can be
more easily spotted for removal.
It is a recommended practice to evaluate each tree before pruning. If necessary,
alternate the schedule according to condition. For example, if oak tree dieback (caused
by Diplodia quercina) is found, pruning should be performed between November and
January. If oak twig blight (caused by Cryptocline cinerescens or Discula quercina) is
identified, reschedule pruning during dry weather in the summer or fall. To prevent
trees from the attack of boring insects, pruning should be performed during the least
favorable time for these insects to relocate, commonly in cooler winter months.
During bird nesting season, DRP Forestry staff does not schedule large pruning projects
for park trees. Forestry staff also takes special precautions to watch for signs of bird
activity on the ground and scouts trees for occupied nests before beginning pruning
projects. On occasions when the birds are present and the tree does not appear to be at
risk, the pruning project is delayed for a few months.
TREE CARE MANUAL/Tree Maintenance Guidelines Page 7 of 15
3.20.5 Pruning Stressed Trees
Pruning is cutting into a tree's life tissue. Therefore, it is important to apply pruning
practices that do not compound stress. This is especially true if pruning is performed on
trees that are already stressed from various other factors. When a tree is stressed, its
defense system is weakened. When defense systems are weakened and a pathogen is
present, infection usually takes place that may result in tree decline.
➢ If the tree has been recently damaged by injury or disturbance, remove all broken
branches. If necessary, restore the crown to preserve structural integrity.
➢ If the tree is stressed from receiving inadequate care, prune moderately to clean
the crown, thin and reduce end weight, or restore the entire crown.
Care must be taken to prune stressed trees during the best time of the season for the
species and when common pests are not present.
3.20.6 Pruning Young Trees
The average life expectancy for trees growing in harsh urban conditions is less than 20
years. Pruning trees early can improve tree vitality and preserve structural integrity.
They may be pruned at planting time to remove branches damaged during handling and
transplanting, and to establish the tree's permanent framework. Lower branches are
typically retained as "temporary branches" — they serve to strengthen and protect the
trunk. The following should be pruned:
➢ Broken, dead, and diseased branches
➢ Sucker growth arising from the base or watersprouts growing vertically from a
branch
➢ Crossing and rubbing branches
Staking may be necessary to temporarily support, anchor, or protect young trees.
Subtle pruning cuts have a dramatic effect on the future structure of a tree. The goal is
to develop trees with one dominant leader, strong and balanced scaffold branches,
good trunk taper, and to correct weaknesses such as included bark or codominant
stems
It is important for the field maintenance staff to:
➢ Monitor and adjust rubbing tree stakes and ties that are too tight. In a park
setting, most properly developing trees should have stakes removed after three
to five years.
➢ Maintain temporary branches for the first three to five years after the tree has
been planted. To allow mowing and prevent breaking, shorten temporary
branches to 12-18 inches as shown below.
TREE CARE MANUAL/Tree Maintenance Guidelines Page 8 of 15
Gilman, E.F. 2002. An Illustrated Guide to Pruning
Temporary branches on the lower part of the trunk are to remain for 3-5
years after planting. These branches will nourish the trunk, build caliper, and
prevent over extension of the leader. Be sure to shorten any temporary
branches growing into the permanent canopy.
Temporary branches are crucial in the development of young trees. They allow for flow
of photosynthates, nutrients and water between the trunk and temporary branches and
leaves. Temporary branches aid in the development of a robust tapered trunk, and can
result in a tree that withstands greater stress from wind, stands erect, and is better
equipped to support a crown mass at maturity. These branches should be shortened to
about 12-18 inches and remain for at least 3-5 years after planting. When they are
permanently removed they should be pruned according to established guidelines. Do
not "flush cut' or leave stubs, which are invitations to disease.
3.30 Prohibited Acts
Any damaging acts or alterations to protected trees are prohibited. We discuss a few of
the most common harmful practices below.
3.30.1 Excessive pruning
The most common offense in urban areas is excessive pruning. People often see
different tree pruning styles and assume that these practices are good for trees.
Forestry staff is cautious to trim only as much as necessary to achieve these results: a
healthy and beautiful tree, increased public awareness, and the greatest ecological
benefit.
3.30.2 Topping and Heading.
Topping is the indiscriminate cutting back of tree branches to stubs or lateral branches
that are not large enough to assume the terminal role.
"Topping is perhaps the most harmful tree pruning practice known. Yet despite
more that 25 years of literature and seminars explaining its harmful effects,
topping remains a common practice" ISA, Why Topping Hurts Trees.
TREE CARE MANUAL/Tree Maintenance Guidelines Page 9 of 15
Other names for topping include "heading", "tipping", "hat -racking", and "rounding over".
A common misconception is that a tall tree poses a hazard and its height should be
reduced to make it safer. Topping may reduce the hazard in the short term, but is not a
viable method for height reduction.
Topping stresses trees -- Topping often removes 50-100% of the leaf -bearing crown
of a tree. Since the leaves are the "food factories" of a tree, topping can temporarily
"starve" a tree. The severity of the pruning triggers a kind of survival mechanism. The
tree activates latent buds, forcing rapid growth of multiple shoots below each cut. The
tree needs to form a new crop of leaves as soon as possible, and if it doesn't have the
stored energy to do this, it is seriously weakened and may die.
A stressed tree is more vulnerable to insect and disease infestations. Large, open
pruning wounds expose the sapwood and heartwood to attack. The tree may lack
sufficient energy to chemically "defend" the wounds against invasion. Some insects are
actually attracted by chemical signals to stressed trees.
Topping causes decay -- Cuts made along a limb between lateral branches create
stubs. The tree may not be able to close these wounds and the exposed tissues are
subject to decay. Normally a tree will compartmentalize these decaying tissues, but few
trees can defend against multiple, severe wounds caused by topping.
Topping can lead to sunburn -- When leaves are removed the remaining branches
and trunk are suddenly exposed to high levels of light and heat. The result may be
sunburn of the tissues beneath the bark. This can lead to cankers, wood decay, bark
splitting and death of some branches.
Topping may create hazards -- Stubs left from topping usually decay. Shoots that are
produced below the cut are often weakly attached and may be at risk of failure. Unlike
normal branches that develop normally, the outermost layer of the parent branches only
connects these new shoots. The new shoots grow quickly and may become heavy and
prone to breakage.
Topping makes trees ugly -- The natural branching structure of a tree is a biological
wonder. Topping removes the ends of the branches, often leaving ugly stubs. Topping
destroys the natural form of a tree.
3.30.3 Other prohibited actions
➢ "Lions tailing". This practice removes all or most secondary and tertiary branches
from the interior portion of the crown, leaving most live foliage at the perimeter of
the canopy.
➢ Excessive root pruning that damages more then 25% of the root zone.
➢ Excessive tree raising.
➢ Compacting soil within the dripline because of unnecessary driving or parking.
➢ Recreation activities that will damage trees.
TREE CARE MANUAL/Tree Maintenance Guidelines Page 10 of 15
3.40 Maintaining Tree and Turf Association
Trees and turf are mutually exclusive in nature. It is rare to see many trees growing in
grasslands and conversely, grass is not common on the forest floor. Each plant group
has its own demands and strategies to inhibit the growth of the other, leading to
competition for water, nutrients, sunlight, and rooting space. Turf requires morning
sunlight for optimum growth, health, and stand density. Golf course design considers
tree location and species selection with respect to placement of turf areas. The DRIP
uses many design alternatives at their golf courses —for example, aligning maintenance
requirements by using indigenous plants, or using mulch to minimize compaction and
enhance tree health. More information is provided in Appendix P in Training Leaflet 3 —
Trees and Tun` Associations.
3.40.1 Mulching as Turf Alternative.
Mulching the root areas of trees is perhaps the simplest but most beneficial practice we
can perform to enhance tree health and minimize competition with turf. The application
of mulch can:
➢ aid in soil moisture retention
➢ moderate soil temperature
➢ eliminate weed and turf competition and reduce allelopathic interference
➢ condition the soil and improve microbial activity
➢ reduce irrigation requirements
By design, mulch keeps mowing equipment from damaging tree trunks and eliminates
the need for herbicide applications. It is also aesthetically pleasing.
Mulch should be applied between 4 and 6 inches deep and kept a minimum of 6 inches
away from tree trunks. Mulching a large area will visually and physically tie groupings of
trees together.
3.40.2 Mowing and other Equipment
Mowing equipment, spray rigs, aeration equipment, and skip loaders can all cause
irreversible mechanical injury to trees. Severe damage can occur and tree trunks can
eventually become girdled and die when trees are hit repeatedly with equipment such
as string trimmers. Sometimes referred to as "mower blight', trunk wounds also serve
as entry points for diseases, borers, or other insects.
The DRIP commonly uses mulch around trees as a deterrent against this kind of
damage. Tree guards are also used to protect the trunks of young trees. They should be
routinely examined and either readjusted or removed as trees mature.
3.40.3 Fertilizing Standards and Mycorrhizae Treatments
Trees require certain essential elements to function and grow. Although turf in City
parks is fertilized regularly, trees typically do not require supplemental fertilizer for
optimum growth. With the exception of nitrogen, most soils supply adequate amounts of
nutrients. Excess and unnecessary fertilizer applications can predispose trees to
disease and insect infestation, pollute ground water, and create salt buildup in the soil. If
a tree appears to have a nutrient deficiency, a laboratory soil or foliar analysis should be
performed before fertilizer is applied.
TREE CARE MANUAL/Tree Maintenance Guidelines Page 11 of 15
Mycorrhizae are root structures that are created when young lateral roots are invaded
by specific fungi that form symbiotic associations to the advantage of each. Plants
benefit from mycorrhizae by enhanced nutrient uptake and may improve water
absorption and drought resistance.
The DRP has had success applying mycorrhizae adjacent to trees growing in infertile
urban soils. Analysis of tree roots for the presence of native mycorrhizal fungi should be
performed before application of inoculants.
3.50 Watering Practices
Water needs of trees vary by species, tree age, soil type, and environmental conditions.
The relationship between soils, plants, and water is a complex subject and is only briefly
discussed in this section.
Supplemental irrigation for mature trees should be deep and infrequent. Deep watering
can increase drought tolerance and encourage deep roots less likely to damage
hardscape. Excess irrigation can promote root -rotting fungi and lead to tree decline,
whereas frequent shallow watering encourages surface roots that provide poor
anchorage.
Watering frequency depends on temperature, humidity, wind, soil type, and drainage.
The DRP uses a soil probe to determine soil moisture and establishes its irrigation
schedules accordingly. The Department endeavors to water in the early morning when
there is little wind, irrigation is less likely to interfere with park activities, and foliage is
allowed to dry during the day, an important consideration for trees that are susceptible
to fungal -related foliar diseases.
Proper irrigation is key to the survival of newly planted trees. If rainfall is not sufficient
for tree establishment, supplemental water is necessary. The best indicator is to probe
the soil to determine the moisture content of root ball.
The DRP avoids using overhead irrigation that wets tree canopies or tree bases,
especially of those trees that are susceptible to foliar diseases or diseases caused by
crown- or root -rotting fungi.
Native trees adapt to environmental conditions of the region and after establishment
rarely require supplemental irrigation. Planting native and drought tolerant trees in turf -
dominated City parks requires careful irrigation management.
More information on watering practices can be found in Appendix P — Leaflet 4 -
Watering Practices and Leaflet 7 — Maintaining Young Trees.
3.60 Soil Condition
Soil compaction is the largest single factor responsible for the decline of mature trees.
Ninety percent of the damage to the upper 18 inches of soil occurs during the first pass
by heavy equipment and cannot be reversed. DRP staff makes every effort and
encourages the KOOL Program (Keep Off Our Lawns) to avoid soil compaction by not
parking or driving within the dripline of trees.
' Arboriculture, p. 107.
TREE CARE MANUAL/Tree Maintenance Guidelines
Page 12 of 15

The following aeration methods and drainage systems are recommended to improve
soil porosity in compacted soils:
3.60.1 Drainage
Adequate drainage must be provided when planting new trees. If trees are planted in
impermeable soil with low water infiltration rates (less then 2 inches per hour), the DRP
may employ one of the following drainage systems:
➢ French drains, at a minimum depth of three feet
➢ Drain tiles or lines installed beneath trees
➢ Drain holes augered at the bottom of the planting pit at a specified diameter and
depth, and filled with medium-sized sand or fine gravel.
3.60.2 Aeration
Aeration of soil supporting turfgrass is performed with caution and avoided within the
tree's drip line. Hollow -tine aeration can lead to the elimination of tree roots in the upper
few inches of soil and usually results in improved turf root growth. Soil that is disturbed
or compacted within the dripline is loosened or aerated to promote root growth and
enhance tree vitality. One of the following aeration methods should be specified to
correct compacted soil conditions:
➢ Vertical mulching. Auger holes 2-4 inches diameter, 2-3 feet deep on 4-foot
centers and backfill with porous material such as perlite, vermiculite, volcanic
rock, peat moss or mixture thereof.
➢ Radial Trenching. Using an air excavator, excavate a soil trench 3-6 inches wide
and a minimum of 12 inches deep from approximately three feet from the trunk
radiating out to the edge of the dripline. The trenches shall radiate out from one
foot at the closest point.
➢ Soil Fracturing. Using pneumatic soil probe (e. g., Gro-gun) to deliver a sudden
burst of air that cracks loosens or expands the soil to improve the root -growing
environment.
➢ Subsurface injections under moderate hydraulic pressure, using a three-foot
probe and applied on 3-foot centers within the dripline.
3.70 Insect and Disease Control
Appropriate species selection and providing for a tree's basic growth requirements are
critical components of pest management. Proper planting techniques, irrigation, pruning
and aftercare all contribute to a plant's tolerance of and defense to pests.
Many factors contribute to plant stress and pest susceptibility. Drought conditions and
smog, for example, are stressors. In the 1980's, thousands of blue gum Eucalyptus
trees died when drought increased their susceptibility to longhorn borers. Years of
repeated defoliations caused by the redgum lerp psyllid has resulted in the death of
thousands of Eucalyptus trees and the removal of 5,000 specimens from City parks.
A vigorous plant is best equipped to stave off pest infestation.
TREE CARE MANUAL/Tree Maintenance Guidelines Page 13 of 15
DRP implements Integrated Pest Management (IPM), a strategy that is designed to
prevent and suppress pest problems with minimum adverse effects on human health,
the environment, and non -target organisms. The Vegetation Management Unit of the
Forestry Division is responsible for pest identification and actions taken or
recommended to control, and if needed, eradicate pests before damage to a tree is
irreversible. It is important for DRP staff to notify the Unit at (213) 485-4826 with your
observations and/or concerns. Accurate timing is critical for success.
3.80 Training Material (Appendix P)
The DRP believes that providing training and sufficient information to enhance the
knowledge of those involved in maintenance, construction, or recreation activities
around trees is the best solution to unintentional tree damage. Training also provides
additional information that helps field staff make their own decisions.
Training material is available in various formats:
➢ leaflets that may be distributed during Tailgate meetings
➢ informational brochures
➢ PowerPoint training presentation (available in outline form)
The information included in the training material focuses on the most common situations
and problems occurring in our parks and explains how trees respond to these situations.
The material offers recommendations, alternatives, and practices to avoid or apply
when working around trees. If additional training material not provided in Appendix P is
required, please contact the Forestry office. Appendix P includes the following:
➢ Oak Tree Ordinance
➢ Tree Wounds
➢ Tree and Turf Associations
➢ Watering Practices
➢ Mulch and Its Benefits
➢ Tree Staking
➢ Maintaining Young Trees
➢ Tree Care Presentation (PowerPoint)
➢ Video Guide —Tunneling and Trenching
➢ Brochures of The Green in Your City series
3.90 Tree Inventory
The successful management of any resource begins with an inventory of the resource,
and the urban forest is no exception. Inventories are essential for planning, scheduling,
and monitoring maintenance tasks, and in assisting in management decisions,
particularly when developing a monetary budget.
The DRP is exploring means to inventory an estimated 800,000 park trees. Currently,
the Forestry staff is investigating a variety of inventory systems to provide the level of
information needed to make sound decisions. Since park trees grow randomly in open
space, it is difficult to refer to and identify tree locations. When using fixed reference
points is not possible, a global positioning system (GPS) and geographic information
TREE CARE MANUAL/Tree Maintenance Guidelines Page 14 of 1.5
systems (GIS) are best for collecting and representing data. GPS employs a handheld
unit that locates a point (e.g.,. a tree) on the ground via a satellite system. This
information can then be readily transferred to GIS. These systems of collecting data
provide "layers" of information that is important to other park functions, and can reduce
field data collection time by 30 percent.
A tree inventory provides descriptions of tree location, species, size, condition, and
management needs.. The inventory information is used to develop integrated pest
management strategies by identifying species to avoid, analysis of specific problems,
location of trouble spots, and pest monitoring: this data can transform the DRP's
approach to park tree management from reactive to proactive. The information also can
be used to enhance the ecological value of park trees and provide direction regarding
the planting of trees that are attractive and beneficial to wildlife and the connection of
wildlife corridors.
An inventory is essential in locating planting sites, identifying management needs, and
locating hazardous trees in need of pruning or removal. The inventory also can be used
in public relations as a news release that describes public tree resources, both in terms
of the number and value of trees.
Once completed, the inventory will be updated on a continuous basis by connecting to
an existing computerized Forestry Work Order System and by collecting data regarding
newly planted trees. In summary, the tree inventory for park trees carried out on
continuous basis will establish a baseline of where the tree population has been, where
it is now, and where it is going in the future.
This information was written at a time (April 2003) when funds for the tree inventory
have not yet been identified. When the tree inventory program is in progress, this
section will be re -written and will provide more specific information on the system used
in our Department.

Trees
Why are trees protected?
The City's Tree Preservation Ordinance recognizes
trees as a valuable natural resource that helps define
the community's character; hence, are worthy of
preservation. Trees provide scenic beauty, prevent soil
erosion, provide shade and maintain temperate climate,
provide wind buffer, and act as a filter to remove
pollution from air.
What trees are protected?
All "heritage trees" are protected under the City's
ordinance, including those on private property.
"Heritage trees" means any tree, shrub, or plant that
meets at least one of the following criteria:
1. All Eucalyptus windrows; or
2. All woody plants in excess of 15 feet in height and
having a single trunk circumference of 15 inches or
more, as measured 24 inches from ground level; or
3. Multi -trunk tree(s) having a total circumference of 30
inches or more, as measured 24 inches from ground
level; or
4. A strand of trees the nature of which makes each
dependent upon the others for survival; or
5. Any other tree as may be deemed historically or
culturally significant by the Planning Director
because of size, condition, location, or aesthetic
qualities.
Exemptions: Fruit or nut bearing trees, trees in public
right-of-way where their removal or relocation is
necessary to obtain adequate line -of -sight for motorists
as required by City Engineer, trees which City Engineer
has determined will damage existing public
improvements, and trees which require maintenance or
removal to protect existing electrical power or
communication lines or other utility property.
What about street trees?
Trees within the public right-of-way are City street trees.
Sometimes, particularly where sidewalk is curb
adjacent, the street tree may be located behind the
sidewalk within a special easement. The Planning or
Engineering Department can determine whether a tree
behind a sidewalk is a City street tree. For further
information about maintenance of street trees, contact
the City Yard at (909) 477-2730.
Can I remove a tree?
Removal or relocation of a heritage tree, including those
on private property, requires a permit. "Remove"
includes any act which will cause a heritage tree to die
including, but not limited to, acts which inflict damage
upon root systems, bark or other parts of tree by fire,
application of toxic substances, operation of equipment
or machinery; improper watering; changing natural
grade of land by excavation or filling the drip line area
around the trunk; or by attachment of signs or artificial
material piercing the bark of the tree by means of nails,
spikes, or other piercing objects.
Do I need a permit?
Yes, removal of heritage trees requires a permit.
Contact the Planning Department at (909) 477-2750 to
obtain permits prior to removal. Submittal of complete
information, including plot plan and photographs, will
expedite your permit processing. The Tree Removal
Permit application, available from the Planning
Department, lists submittal requirements. For more
information about valid reasons for removal and
procedures, see reverse side of this handout.

Why can trees be removed?
The City's Tree Preservation Ordinance lists reasons
why trees may be considered for removal, such as poor
health, weak structure, danger of collapse, damage to
improvements, etc. In reviewing a Tree Removal
Permit request, staff must also consider the necessity
to remove a tree in order to construct improvements,
the number of trees in neighborhood, whether the trees
are required to be saved by any plan, condition of
approval, or designation as an historic landmark. The
Ordinance states that removal is the last resort.
Redesigning planned home improvements to save trees
in place is preferred. If design change is infeasible,
then relocation of the tree by transplanting is the
preferred alternative to removal. An arborist can advise
on the feasibility of relocation.
Tree Care
Each Fall and Winter, rain storms and winds result in
more inquiries about removing trees because of fear
they will topple. The truth is that "Of the hundreds of
thousands of trees growing in Southern California, only
a miniscule amount topples," said consulting arborist
Robert Hansen. Just as taking care of your body is the
best way to insure long-term health, taking proper care
of your tree will result in a healthier, longer life. Regular
pruning and thinning and care by a qualified arborist
can lessen the chance that a tree develops the
problems that may cause it to topple.
Can I prune my tree?
Maintenance of heritage trees on private property is
the responsibility of the property owner. Heritage trees
may be pruned. Improper pruning, such as "topping,"
can damage or kill trees; therefore, care should be
used. The Forest Service has an excellent web site,
complete with illustrations, devoted to how to prune a
tree:
http://www.na.fs.fed.us/spfo/pubs/howtos/ht_prune/prun
001.htm. Copies are also available from the Planning
Department.
What if tree is dead?
Healthy trees may appear dead, even when they are
not, such as deciduous trees that lose their leaves in
winter. The best way to determine the health of a tree
is to contact a professional arborist to inspect the tree.
Like people, trees may be injured or sick, such as
damaged by fire, insect infestation, or fungus, yet with
proper care and time return to good health. Again, the
services of an arborist can determine treatment
methods. If an arborist has determined that the tree is
dead, then it may be removed without a permit.
What about emergencies?
The City's Tree Preservation Ordinance allows the
Rancho Cucamonga Fire Protection District or Planning
Director to determine if a tree is in a dangerous
condition requiring emergency action to remove without
a permit.

Tree Removal Permit Procedures
1. Is removal request in conjunction with a development application?
• If No, then go to question 2.
• If Yes, follow permit process in Ordinance (RCMC 19.08.070.B.) briefly discussed below. At least
10 days notice to adjoining property owners is required before City can make a decision on permit
request.
2. Are more than 5 trees or 50 linear feet of windrow being removed?
• If No, follow simplified permit process in Ordinance (RCMC 19.08.070.A.).
• If Yes, follow permit process in Ordinance (RCMC 19.08.070.B.). At least 10 days notice to
adjoining property owners is required before City can make a decision on permit request. Where
request involves a development application, such as a Tentative Tract Map, Parcel Map,
Conditional Use Permit, or Development Review, then the Tree Removal Permit request shall be
considered by the Planning Commission concurrently with the development application.
