1 Introduction
Dudek evaluated and recorded information about protected trees as defined in Chapter 28, Article III, of the City of
Fontana’s Code of Ordinances (Fontana Code of Ordinances) (City of Fontana 2016) and prepared this arborist report
for the proposed Santa Ana and Almond Avenue Warehouse Project (project) in the City of Fontana (City), California.
Primary topics of this arborist report include evaluations of project-related impacts and recommendations for tree
protection, relocation, removal, and mitigation. The project site is located at Assessor’s Parcel Numbers (APNs) 0236-
171-47, 0236-171-89, 0236-171-87, 0236-171-88, 0236-171-85, 0236-171-80, 0236-171-79 in the City of Fontana,
San Bernardino County, California.
This arborist report provides a summary of Dudek’s site and tree evaluations within and immediately adjacent to
the proposed development and infrastructure improvement areas (survey area). The trees on site are comprised of
multiple ornamental species, including remnants of two red gum eucalyptus (Eucalyptus camaldulensis) windrows.
With the exception 11 trees located within a single windrow, a majority of the surveyed trees are scattered
throughout the survey area.
Dudek’s International Society of Arboriculture (ISA) Certified Arborists performed various tasks associated with
surveying, inventorying, and evaluating the condition of the property’s trees, as described in this report. The purpose
of this arborist report is to present the physical characteristics, mapped locations, impact and preservation totals,
and recommended protected tree impact mitigation. The tree quantities and related project impacts have been
analyzed and are reported in the following sections.
In summary, the project site exhibits industrial- and residential-related activities and is heavily disturbed. The site’s
historic windrow trees (11 trees) are primarily located within a single windrow, while the remaining trees on site are
scattered throughout the property (78 trees). The 89 trees consist of 78 heritage trees and 11 other (non-protected)
trees.
In total, 89 trees are located on or immediately adjacent to the project site, and 78 would require removal to
accommodate the proposed project. The remaining 1 trees (encroached), are located within the historic windrow,
can be protected in place. Of the 78 trees requiring removal, one is recommended for removal based on health
(dead). As such, only 77 trees require mitigation in accordance with the Fontana Code of Ordinances. The 89 trees
are composed of 11 protected trees (11 heritage) and 78 other trees. The single tree recommended for removal
based on health does not require mitigation, as stated in Section 28-65 of the Fontana Code of Ordinances (City of
Fontana 2016). None of the impacted trees are considered candidates for relocation.
1.1 Site Description
The project site is comprised of seven individual locations. The seven individual locations are comprised of the
following addresses: 14205, 14221, and 14241 Santa Ana Avenue; and 10922, 20944, 10980, and 10990
Almond Avenue. The project site is specifically located on the corner of Santa Ana Avenue and Almond Avenue,
within a property that is located within Section 27 of Township 1 South Range 6 West of the Fontana, California
7.5-minute U.S. Geological Survey (USGS) quadrangle, as shown on Figure 1, Regional Map, and Figure 2, Vicinity
Map. The property is approximately 8.72 acres and is bordered by Santa Ana Avenue to the north, Almond Avenue
to the east, and private property to the south and west. The property is currently comprised of residential housing
and industrial businesses. The vegetation on site is primarily composed on non-native vegetation and ornamental
tree species.

1.2 Project Description
The project includes construction of an industrial warehouse building totaling approximately 204,695 square feet,
as well as associated onsite improvements on an approximately 8.7-acre property. The project site is composed of
7 parcels (APNs 0236-171-47, 0236-171-89, 0236-171-87, 0236-171-88, 0236-171-85, 0236-171-80, 0236-171-79).
In addition to the industrial warehouse building, the project would include approximately 50,380 square feet of
landscaping area as well as surface parking for passenger vehicles and trucks.

2 Methods
2.1 Individual Protected Tree Evaluation
Dudek mapped and collected individual tree attribute information for all protected trees meeting the City’s definition
of a protected tree—which includes heritage, significant, and specimen trees—and other trees within and adjacent to
the project limits. The location of each individual protected tree was mapped using a Trimble Pathfinder Pro XH GPS
receiver (Pathfinder) (see Appendix A, Tree Location Exhibit, for tree locations). The Pathfinder has a horizontal
accuracy of 1 meter (1 sigma) using differential code positioning techniques. Since tree canopies can sometimes
cause loss of satellite lock by blocking the line of sight to satellites, an electronic compass and a reflectorless
electronic distance-measuring device were also used in mapping tree locations. The electronic distance-
measuring/compass combination operates in concert with the Pathfinder system to position offsets, and offset
information is automatically attached to the GPS position data string. All trees were tagged in the field with an
aluminum tree tag bearing a unique identification number. A tag was placed on the trunk of each inventoried tree,
and each tag number corresponds with the individual tree data presented in Appendix B, Tree Information Matrix.
Concurrent with tree mapping efforts, Dudek arborists collected tree attribute data, including species, quantity of
individual trunks, individual trunk diameters, overall height, canopy extent, general health and structural conditions,
and overall condition. Trunk diameter measurements were collected at 4.5 feet above natural grade along the trunk
axis, with a few common exceptions. In cases in which a tree’s trunk was located on a slope, the 4.5-foot height
was approximated as the average of the shortest and longest sides of the trunk (i.e., the uphill side and downhill
side of the tree’s trunk, respectively), and the measurement was made at the circumference of the trunk at this
point. Tree height measurements were ocular estimates made by experienced field arborists. Tree canopy
diameters were typically estimated by pacing off the measurement based on the arborist’s stride length or by
visually estimating the canopy width. The tree-crown diameter measurements were made along an imaginary line
intersecting the tree trunk that best approximated the average crown diameter.
Pursuant to the Guide for Plant Appraisal (Council of Tree and Landscape Appraisers 2000), tree health and structure were
evaluated with respect to the following five distinct tree components: roots, trunks, scaffold branches, small branches, and
foliage. Each component of the tree was assessed with regard to health factors such as insect, fungal, or pathogen damage;
fire damage; mechanical damage; presence of decay; presence of wilted or dead leaves; and wound closure. Components
were graded as good, fair, poor, and dead, with good representing no apparent problems and dead representing a dying
and/or dead tree. This method of tree condition rating is comprehensive, and results in ratings that are useful for
determining the status of trees based on common standards. Trees in natural settings have important habitat value, as
evidenced by numerous cavity nesters and insects that thrive on and within trees, even when they are considered in poor
structural or health condition. However, this assessment focuses on tree conditions concerning health and structure for the
purposes of analyzing potential project impacts, and where necessary, providing recommendations for mitigating potential
tree hazards, such as trees with weak limb attachments, cavities and rot, or excessive lean that would not be appropriate
for inclusion in a developed landscape. Each tree was assigned an overall condition rating based on component grades.
The overall ratings were graded on a percentage scale that ranges from 10% (dead) to 100% (excellent condition).
Upon completion of field data collection and mapping, raw GPS data were post-processed using GPS Pathfinder Office
(version 5.40), and individual tree location data were compiled and updated in a geographic information system (GIS). The
digital tree locations were linked to individual tree identification numbers and associated tree attribute data. This data set
was then evaluated using ArcGIS (version 10.1) software to determine the position of individual trees related to the project
development areas. Data resulting from this analysis were used to evaluate the individual tree impact totals in this report.

2.2 Scope of Work Limitations
The tree assessments did not include root crown excavations or investigations, aerial evaluations, or internal
probing; therefore, the presence or absence of internal decay or other hidden inferiorities in individual trees could
not be confirmed. It is recommended that any large tree proposed for preservation in an area that receives human
use be thoroughly inspected for internal or subterranean decay by a qualified ISA Certified Arborist before finalizing
preservation plans.
2.3 Individual Protected and Significant Trees
There are 11 trees located within and immediately adjacent to the project site that meet the City’s definition of protected
trees. Of the 11 protected trees found within the tree survey area, all 11 are considered heritage trees as defined in
Section 28-63 of the Fontana Code of Ordinances. The 11 protected heritage trees are composed entirely of red gum
eucalyptus. The 11 protected heritage trees are all located within a single east–west-trending remnant windrow. The
Tree Location Exhibit (Appendix A) presents the location of the individual trees mapped and assessed for the proposed
project.
Overall, the trees exhibit growth and structural conditions that are typical of their locations as agricultural windrow
and disturbed landscape trees. The trees include various trunk and branch maladies, and varying health and
structural conditions. As presented in the Tree Information Matrix (Appendix B), 81.81% (9 trees) are in fair health
condition, and 18.2% (2 trees) are in poor health. Structurally, 27.3% (3 trees) of the individually mapped protected
trees are considered to exhibit fair structure, and72.7% (8 trees) exhibit poor structure
Fair condition trees are typical, with few maladies but declining vigor. Poor condition trees exhibit declining vigor,
unhealthy foliage, poor branch structure, or excessive lean. The trees have overall ratings that range from 40% to
60%. As presented in the Tree Information Matrix (Appendix B), 27.3% (3 trees) are in fair condition, 54.5% (6 trees)
are in poor condition overall, and 18.2% (2 trees) are in very poor condition overall.
Protected trees within the tree survey area vary in size and stature according to species and available growing space.
The site’s protected trees are primarily single-stemmed trees and have diameters ranging from 12- to 24- inches. Tree
heights vary from 15 feet to 60 feet. Tree canopy extents range from 10 feet to nearly 40 feet across at their widest
point.
One pest, the eucalyptus tortoise beetle (Trachymela sloanei), was noted on the protected trees. The beetle chews irregular
holes along the edges of a tree’s leaves (similar to a paper hole-punch). The pest is not known to directly kill trees; however,
it can be a secondary agent when major defoliation occurs related to pest population spikes while the tree is subject to
other issues, such as drought. In these cases, it can contribute significantly to tree decline and or loss.
2.4 Other Trees within Project Limits
There are 78 other trees that do not meet the City’s definition of heritage, significant, or specimen tree located in
and adjacent to the tree survey area. The 78 other trees are comprised of a variety of individual tree species as
described in Appendix B. As depicted on the Tree Location Exhibit (Appendix A), the 78 other trees are scattered
throughout the property.

Overall, the other trees exhibit growth and structural conditions that are typical of their locations. Like the
protected trees, the trees include various trunk and branch maladies. As presented in the Tree Information Matrix
(Appendix B), 12.8% (10 trees) exhibit good health, 69.2% (54 trees) exhibit fair health, 16.7% (13 trees) exhibit
very poor health, and 1.3% (1 tree) is dead. Structurally, 7.7% (6 trees) exhibit good structure, 62.8% (49 trees) of
the individually mapped other trees are considered to exhibit fair structure, 28.2% (22 trees) exhibit very poor
structure, and 1.3% (1 tree) is dead.
The other trees within the survey area vary in size and stature according to species and available growing space.
The site’s other trees are a mixture of single- and multi-stemmed trees with single and combined trunk diameters
(diameter at 4.5 feet above natural grade) ranging from 1 inch to 36 inches. Tree heights vary from 6 feet to 65
feet, and tree canopy extents range from 4 feet to approximately 45 feet across at their widest point.
One pest, the eucalyptus tortoise beetle, was noted on the protected trees. The eucalyptus tortoise beetle chews irregular
holes along the edges of a tree’s leaves (similar to a paper hole-punch). The pest is not known to directly kill trees;
however, it can be a secondary agent when major defoliation occurs related to pest population spikes while the tree is
subject to other issues, such as drought. In these cases, it can contribute significantly to tree decline and or loss.

3 Tree Preservation
3.1 Regulatory Definitions and Requirements
The following subsections summarize the relevant policies regulating tree impact and removal associated with the project.
3.1.1 City of Fontana
The City’s Tree Preservation and Protection Ordinance requires that a tree report be prepared for removal of
protected tree species. The Tree Preservation and Protection Ordinance is as follows (City of Fontana 2016):
Section 28-63 – Definitions
• Tree means any woody perennial plant, usually having a single main axis or trunk and exceeding ten feet
in height at maturity, including specimens of such plants having twin or multiple trunks, and shall include
any species of tree, shrub or plant described in the master plan of parkway trees or in the master tree list.
• Protected tree means any heritage, significant or specimen tree subject to this article or other such tree
identified by a federal or state agency as endangered or sensitive species.
• Significant tree means any tree that is one of the following species; Southern California black walnut
(Juglansa californica) [sic], coast live oak (Quercus agrifolia), Deodora cedar (Cedrus deodora) [sic],
California sycamore (Platanus racemosa), or London plane (Platanus acerifolia).
• Specimen tree is defined as a mature tree (which is not a heritage or significant tree) which is an excellent
example of its species in structure and aesthetics and warrants preservation, relocation or replacement as
provided in sections 28-66, 28-67 and 28-68. Specimen trees shall not include any tree located on a private
parcel of property of less than one acre zoned for residential use.
• Windrow means a series of trees (minimum of four), usually a variety of eucalyptus, planted in a closely spaced line
no more than ten feet apart to provide a windbreak for the protection of property and/or agricultural crops.
• Heritage tree means any tree which:
1. Is of historical value because of its association with a place, building, natural feature or event of local,
regional or national historical significance as identified by city council resolution; or
2. Is representative of a significant period of the city’s growth or development (windrow tree, European
Olive tree); or
3. Is a protected or endangered species as specified by federal or state statute; or
4. Is deemed historically or culturally significant by the city manager or his or her designee because of
size, condition, location or aesthetic qualities.
Section 28-64 – Permit required for removal of heritage, significant and specimen trees
Except as provided in section 28-65, no person shall remove or cause the removal of any heritage, significant or
specimen tree unless a tree removal permit is first obtained.
ARBORIST REPORT FOR THE SANTA ANA AND ALMOND WAREHOUSE PROJECT
1422
12 May 2022
Section 28-65 – Tree replacement and permit not required
No permit or replacement shall be required for:
1. Removal of trees planted, grown and/or held for sale by licensed nurseries and/or tree farms or the removal
or transplanting of such trees pursuant to the operation of a licensed nursery and/or tree farm.
2. Emergency or routine trimming or pruning to protect or maintain overhead public utility lines, existing
subsurface water lines, sewer or utility lines.
3. Removal of damage parts of a heritage, significant or specimen tree which has sustain an injure d
trunk, broken limbs, or uprooting as a result of storm damage or other acts of God, which create a
hazard to life or property.
4. Removal of trees which are determined to be diseased and/or dead by a certified arborist and approved by
the staff.
5. Removal of trees which are determined to be hindering the safe application or installation of traffic
control devices or roadway improvements in the public right-of-way or trees which hinder the line of site
as determined by the city engineer.
6. Removal of trees which are determined to be within the ultimate right-of-way as shown within the circulation
element of the city’s general plan.
Section 28-67 – Tree Replacement or relocation
a. Heritage, significant or specimen tree preservation on the site is preferred to relocation or replacement.
Relocation is subject to a written report by a certified arborist on the feasibility of transplanting the subject
tree. In the event that a permit is issued by the city for the removal of any heritage, significant or specimen
tree as provided in sections 28-64 and 28-68, such trees removed shall be replaced with a species
designated by the staff according to the following guidelines, unless the staff determines that replacement
is inappropriate:
1. Where existing eucalyptus windrows are to be removed along the existing or ultimate public right-of-
way (R.O.W.), as shown within the circulation element of the city’s general plan, they shall be replaced
with appropriate street trees to be determined by the staff of not less than a 15-gallon size in a ratio of
one tree from the city’s approved tree list for every one removed. Eucalyptus windrow trees not along
the existing public right-of-way which cannot be preserved or relocated shall be replaced according to
the guidelines established in subsection (a)(2) of this section.
2. All heritage and significant trees shall be replaced with a species designated by the designated staff
according to the species, age, size, structure, and trunk diameter, graded on a scale from ten percent to
100 percent according to Table No. I.

d. The replacement trees for heritage, significant and/or specimen trees shall be exclusive of the trees
required as part of the standard landscape requirements.
e. The replacement trees shall be guaranteed for one year. The applicant shall file a cash bond with the city
community development department in an amount to be determined by the staff to assure performance of
this guarantee.
f. A tree that is determined by a certified arborist to be firewood harvested or stump regrowth shall be
removed and replaced with one 15-gallon tree of a species to be determined by the staff.
g. In lieu of the replacement trees as required by subsections (a), (b) and (c), a cash equivalent as determined by the
staff may be deposited with the city in the tree account. This account is established to purchase, plant or relocate

3.1.2 Migratory Bird Treaty Act
The Migratory Bird Treaty Act requires tree removal and potentially disturbing construction activities to occur during
certain periods to avoid harassment of nesting birds. According to the Migratory Bird Treaty Act, no construction or
other disturbing activities can occur within 500 feet of an active bird nest during the period beginning in February
and ending in August of each year. Biological surveys should be conducted to provide clearance for project initiation.

4 Impacts
Tree impacts were determined using GIS technology and spatial locations of trees relative to the project impact
areas (limits of grading). Impacts were further determined based on Dudek’s experience with native and non-native
trees, and trees’ typical reactions to root disturbances from construction activities, such as soil compaction,
excavation, and remedial grading. The impact analysis results in this arborist report were used for developing
appropriate mitigation measures for the project.
Impacts to trees can be classified as direct or indirect. Direct impacts to trees related to site improvements are typically
the result of physical injuries or changes caused by machinery involved with the development process. Direct impacts
include tree removal, root damage, soil excavation and compaction, grade changes, loss of canopy, and trunk wounds,
among others. Indirect impacts to trees are the result of changes to the site that may cause tree decline, even when the
tree is not directly injured. Indirect impacts include alterations to stream flow rates, diversion of groundwater flow,
introduction of exotic plant species, and alterations to disturbance regimes. Wider-scale alterations to the area near
trees, as well as specific changes that occur around the trees, are important considerations.
In general, there is a great deal of variation in tolerance to construction impacts among tree species, ages, and
conditions. It is important to know how a certain tree—based on its species, age, and condition—would respond to
different types of disturbance. Mature specimens are typically more sensitive to root disturbance and grade
changes. In general, healthy trees will respond better to changes in their growing environment. Trees in poor health
or under stressed conditions may not be vigorous enough to cope with direct or indirect impacts from construction
activities. The trees on the project site vary in age and condition.
The impact totals are based on conceptual disturbance limits and development plans reviewed as of the publication
of this arborist report. As such, the actual number of trees that are subject to direct and indirect impacts may
change as the detailed site planning process proceeds.
4.1 Direct Tree Impacts – Protected Trees
For the purposes of this arborist report, direct impacts are those associated with tree removal or encroachment within the
tree-protected zone (either the canopy drip line plus 5 feet or 10 feet from the trunk, whichever is greater). Tree removal is
required when the trunk is located inside or within 2 feet of the proposed limits of grading. Encroachment is expected when
soil and roots are disturbed within the tree-protected zone. Table 1 summarizes the total number of trees that are expected
to be subject to direct construction-related impacts. In total, 11 protected trees would be encroached upon. The locations
of impacted trees are presented by impact type in Appendix C, Tree Disposition Exhibit. Representative site photographs
are in Appendix D.

4.2 Direct Tree Impacts – Other Trees
In total, the project would directly impact 78 other (non-protected) trees. In total, 78 protected trees would experience
direct impacts (removal) and none would be encroached upon. Of the 78 impacts, a total of one was found to be dead.
Additional details regarding “other” tree species can be found in Appendix B, Tree Information Matrix. The locations
of impacted trees are presented by impact type in Appendix C. Representative site photographs are provided in
Appendix D.
4.3 Potential Relocation Candidates
In addition to the general site tree evaluations, Dudek evaluated all of the impacted protected trees for their potential for
preservation in place or relocation. Trees identified as candidates for preservation in place and relocation typically exhibit
good health (new growth and vigor) and structure (trunk/branching); have no uncorrectable, outwardly detectable defects;
and show no signs or symptoms of serious pest infestation or species-specific pathogens. For the trees to avoid incidental
damage during construction or relocation, preservation and protection measures must be provided before, during, and after
the construction phase. Appendix E, Tree Protection Measures, provided recommended measures for implementation
before, during, and after the construction phase.
None of the protected or other trees located on the project site are considered suitable candidates for relocation.
Tree relocation is a very stressful process that requires ideal tree candidates that are healthy, have good
structure, are not too large, and meet other criteria important to their long-term survival. None of the trees
assessed as part of this arborist report meet these requirements. Individual tree dispositions and locations are
provided in Appendices B and C, respectively.
4.4 Recommended Tree Removal – All Trees (Health
and Structure)
In total, one tree is recommended for removal based on health and/or structure. This singe tree is dead and all would be
directly impacted (removed) by the project. The locations of trees recommended for removal are presented by
impact/recommendation type in Appendix C.
4.5 Tree Impact and Recommended Removal Summary
– All Trees (Project)
In total, 89 trees are located on or immediately adjacent to the project site, and 78 would require removal to
accommodate the proposed project. The remaining 11 trees (encroached) can be protected in place. Of the 78
trees requiring removal, one tree is recommended for removal based on health (dead). As such, only 77 trees
require mitigation in accordance with the Fontana Code of Ordinances. The 77 trees are composed entirely of other
trees. The single tree recommended for removal based on health does not require mitigation, as stated in Section
28-65 of the Fontana Code of Ordinances (City of Fontana 2016).

5 Mitigation
The project’s mitigation plan is consistent with the goals and intent of the Fontana Code of Ordinances. The
recommended mitigation program, as discussed in this section, meets City requirements for tree preservation,
protection, and mitigation.
5.1 Tree Ordinance Replacement Requirements
The Fontana Code of Ordinances requires mitigation for all impacted trees, except for those found to be dead (one
tree) by an ISA Certified Arborist. As such, mitigation will be required for the potential impacts associated with the
project affecting 77 trees. This arborist report discusses tree mitigation plantings to address such impacts and
satisfies the City’s requirements. It is assumed that the mitigation outlined herein is applicable to the impacts
presented by the currently proposed project, and where it is possible to reduce tree impacts through planning and
other efforts identified at later stages of project development, mitigation measures would be reduced proportionally.
The Fontana Code of Ordinances (City of Fontana 2016) requires that a permittee replace protected trees approved
for removal in accordance with Section 28-67 of the Fontana Code of Ordinances, which states the following (City
of Fontana 2016):
Heritage, significant or specimen tree preservation on the site is preferred to relocation or
replacement. Relocation is subject to a written report by a certified arborist on the feasibility of
transplanting the subject tree. In the event that a permit is issued by the city for the removal of any
heritage, significant or specimen tree as provided in sections 28-64 and 28-68, such trees removed
shall be replaced with a species designated by the staff according to the following guidelines,
unless the staff determines that replacement is inappropriate.
Furthermore, the Fontana Code of Ordinances states, “all other trees which are not heritage, significant, or specimen tree
shall be replaced. The size of the replacement tree(s) shall be based on a scale of 10% to 100%. Staff may require that the
ratings be performed by a certified arborist. The arborist report will be approved by staff” (City of Fontana 2016). Detailed
information regarding tree replacement quantities can be found in Section 28-67 of the Fontana Code of Ordinances, or in
the discussion under Regulatory Definitions and Requirements of this arborist report.
5.2 Tree Replacement Plan
The City’s tree replacement requirements are designed to require the planting of protected trees at a replacement ratio
dependent on tree size and overall condition using 15-gallon to 48-inch box trees. As such, and in an effort to meet the
goals and intentions of the Fontana Code of Ordinances, Dudek recommends that the 78 protected and other impacted
trees be mitigated (planted and/or through an in-lieu fee) with 176 trees, as outlined in Table 2 and as required by the City.
Replacement requirements on an individual tree basis are described in Appendix B.

Based on a review of the Landscape Plan (Appendix F), the proposed project would incorporate 49 15-gallon trees,
39 24-inch box trees, and 9 36-inch box trees into the post-development landscape. In total, the proposed
landscape includes the planting of 97 trees. The number of proposed tree plantings is lower than that required by
the Fontana Code of Ordinances. As such, Dudek recommends that the project applicant plant additional trees on
site, and/or work with the City regarding the 79 trees (53 24-inch box, 13 36-inch box, and 13 48-inch box trees;
note 19 15-gallon box trees proposed for planting in the Landscape Plan are substituted for 19 of the required 24-
inch box trees. The city may require these 19 15-gallon trees be upsized to 24” inch box trees in the proposed
landscaping planting plan) that are currently not accommodated on site by the proposed Landscape Plan.
In accordance with Section 28-67 of the City’s Municipal Code, the City may require that in-lieu fees be deposited
in the City’s tree account for the replacement of trees that cannot be accommodated on site (City of Fontana 2016).
This account is established to purchase, plant, or relocate trees in public areas; conduct surveys of trees in public
areas; design master landscape plans to include trees in public areas; and maintain existing heritage, significant,
and/or specimen trees. As such, to assist with project planning, the estimated cost associated with planting is
approximately $150 per tree for 15-gallon replacements, $225 per tree for 24-inch box replacements, $645 for
36-inch box replacements, $2,400 for 48-inch box replacements, and $5,200 for 60-inch box replacements. The
total estimated cost associated with the trees that are currently not accommodated on the proposed Landscape
Plan is approximately $51,510 (53 24-inch box @ 225/tree, 13 36-inch box @ 645/tree, and 13 48-inch box trees
@ $2,400/tree). It should be noted that the final total in-lieu fee would be based on any trees that could not be
planted on site and at the discretion of the City.
5.3 Tree Replacement Species
The proposed tree replacement species, as identified in Appendix F, include a mix of four alternative tree species.
The applicant is proposing the following species for mitigation: blue palo verde (Cercidium ‘Desert Museum’), floss
silk tree (Chorisia speciosa), holly oak (Quercus ilex), Aleppo pine (Pinus halepensis),and bottle tree (Populneus
brachychiton). Details regarding individual proposed planting locations are provided in Appendix F.
5.4 Tree Removal Permit
Consistent with Section 28-64 of the Fontana Code of Ordinances (City of Fontana 2016), a tree removal permit
will be required prior to all tree removals.
ARBORIST REPORT FOR THE SANTA ANA AND ALMOND WAREHOUSE PROJECT
1422
20 May 2022
5.5 Monitoring Program
Trees should be planted in early winter and followed by a 1-year monitoring period, as required by the City. Given
proper installation methods and protective measures, a high survival rate is expected, though some loss may occur.
If a new tree declines to a poor condition (as determined by an ISA Certified Arborist) before the end of the
monitoring period, it should be replaced with a tree of the same species and size per City requirements.
Replacement standards for trees that do not survive should be clearly established. Trees that are lost during the 1-
year monitoring period due to controllable factors—such as mismanagement of water, poor soil conditions, rodent
and other wildlife damage, improper planting, or poor plant performance—are typically replaced at a 1:1 ratio. Tree
loss from natural causes, such as wildfire, flooding, or other natural events, may not necessarily require
replacement because penalties are not usually levied for events beyond the control of the project developer.
General tree planting, maintenance, and protection guidelines are included in Appendix E.
5.6 Tree Protection
Eleven of the trees located adjacent to the project site would be retained. These 11 trees should be preserved in
accordance with the tree protection measures described in Appendix E.

6 Conclusions
In total, 89 trees are located on or immediately adjacent to the project site, and 78 would require removal to
accommodate the proposed project. The remaining 11 trees (encroached) can be protected in place. Of the 78
trees requiring removal, one is recommended for removal based on health (dead). As such, 77 trees require
mitigation in accordance with the Fontana Code of Ordinances. The 77 trees are entirely composed of other trees.
The single tree recommended for removal based on health does not require mitigation, as stated in Section 28-65
of the Fontana Code of Ordinances (City of Fontana 2016). None of the impacted trees are considered candidates
for relocation. As such, based on impacts to 78 other trees within the project site, a minimum of 30 15-gallon, 111
24-inch box, 22 36-inch box, and 13 48-inch box trees require mitigation planting according to Section 28-67 of
the Fontana Code of Ordinances. Based on a review of the Landscape Plan (Appendix F), the proposed project would
incorporate 49 15-gallon trees, 39 24-inch box trees, and 9 36-inch box trees into the post-development landscape.
In total, the proposed landscape includes the planting of 97 trees. The number of proposed tree plantings is lower
than that required (176 trees) by the City’s Municipal Code. As such, Dudek recommends that the project applicant
plant additional trees on site, and/or work with the City regarding the 79 trees (53 24-inch box, 13 36-inch box,
and 13 48-inch box trees; note 19 15-gallon box trees proposed for planting in the Landscape Plan are substituted
for 19 of the required 24-inch box trees). The total estimated cost associated with the trees that are currently not
accommodated on the proposed Landscape Plan approximately $51,510 (53 24-inch box @ 225/tree, 13 36-inch
box @ 645/tree, and 13 48-inch box trees @ $2,400/tree). It should be noted that the final total in-lieu fee would
be based on any trees that could not be planted on site and at the discretion of the City.
Arborist’s Statement
This arborist report provides conclusions and recommendations based on an examination of the trees and
surrounding site by ISA Certified Arborists. Arborists are tree specialists who use their education, knowledge,
training, and experience to examine trees, recommend measures to enhance the beauty and health of trees, and
attempt to reduce the risk of living near trees.
The tree assessments did not include root crown excavations, investigations, or internal probing. Therefore, the
presence or absence of internal decay or other hidden inferiorities in individual trees could not be confirmed. It is
recommended that any large tree proposed for preservation in an area that receives human use be thoroughly
inspected for internal or subterranean decay by a qualified arborist before finalizing preservation plans.
Arborists cannot detect every condition that could possibly lead to the failure of a tree. Trees are living organisms
that fail in ways not fully understood. Conditions are often hidden within trees and belowground. Arborists cannot
guarantee that a tree will be healthy or safe under all circumstances or for a specified period. There are no
guarantees that a tree’s condition will not change over a short or long period due to weather or cultural or
environmental conditions. Trees can be managed, but not controlled.

Tree Protection Measures
Appendix E – Tree Protection Measures
The following sections are included as general guidelines for tree protection from construction
impacts. The measures presented should be monitored by arborists and enforced by contractors and
developers for maximum benefit to the trees.
Tree Protection Measures Prior to Construction
Fencing: All remaining trees that will not be relocated or removed shall be preserved and protected in
place. Trees within approximately 15 feet of proposed construction activity shall be temporarily
fenced with chain link or other material satisfactory to City planning staff throughout grading and
construction activities. The fencing shall be installed 3 feet outside of the dripline of each tree (or
edge of canopy for cluster of trees), be 4 foot tall, and staked every 6 feet. The fenced area shall be
considered the tree protection zone (TPZ) unless proximate construction required temporary removal.
Pre-Construction Meeting: A pre-construction meeting shall be held between all contractors
(including grading, tree removal/pruning, builders, etc.) and the arborist. The arborist will instruct the
contractors on tree protection practices and answer any questions. All equipment operators and
spotters, assistants, or those directing operators from the ground, shall provide written
acknowledgement of their receiving tree protection training. This training shall include information
on the location and marking of protected trees, the necessity of preventing damage, and the discussion
of work practices that will accomplish such.
Protection and Maintenance During Construction
Once construction activities have begun the following measures shall be adhered to:
Equipment Operation and Storage: Avoid heavy equipment operation around the trees. Operating heavy
machinery around the root zones of trees will increase soil compaction, which decreases soil aeration and
subsequently reduces water penetration in the soil. All heavy equipment and vehicles should, at minimum,
stay out of the fenced tree protection zone, unless where specifically approved in writing and under the
supervision of a Certified Arborist or as provided by the approved landscape plan.
Storage and Disposal: Do not store or discard any supply or material, including paint, lumber,
concrete overflow, etc. within the protection zone. Remove all foreign debris within the protection
zone; it is important to leave the duff, mulch, chips, and leaves around the retained trees for water
retention and nutrients. Avoid draining or leakage of equipment fluids near retained trees. Fluids
such as: gasoline, diesel, oils, hydraulics, brake and transmission fluids, paint, paint thinners, and
glycol (anti-freeze) should be disposed of properly. Keep equipment parked at least 50 feet away
from retained trees to avoid the possibility of leakage of equipment fluids into the soil. The effect of
toxic equipment fluids on the retained trees could lead to decline and death.
Grade Changes: Grade changes, including adding fill, are not permitted within the tree protection
zone without special written authorization and under supervision by a Certified Arborist or as
provided by the approved landscape plan. Lowering the grade within this area will necessitate cutting
main support and feeder roots, jeopardizing the health and structural integrity of the tree(s). Adding
soil, even temporarily, on top of the existing grade will compact the soil further, and decrease both
water and air availability to the trees’ roots.
Tree Protection Measures Page 2
Moving Construction Materials: Care will be taken when moving equipment or supplies near the
trees, especially overhead. Avoid damaging the tree(s) when transporting or moving construction
materials and working around the tree (even outside of the fenced tree protection zone). Above
ground tree parts that could be damaged (e.g., low limbs, trunks) should be flagged with red ribbon. If
contact with the tree crown is unavoidable, prune the conflicting branch(es) using ISA standards.
Root Pruning: Except where specifically approved in writing or as provided in Attachment 3, all
trenching shall be outside of the fenced protection zone. Roots primarily extend in a horizontal
direction forming a support base to the tree similar to the base of a wineglass. Where trenching is
necessary in areas that contain tree roots, prune the roots using a Dosko root pruner or equivalent. All
cuts should be clean and sharp, to minimize ripping, tearing, and fracturing of the root system. The
trench should be made no deeper than necessary.
Irrigation: Trees that have been substantially root pruned (30% or more of their root zone) will
require irrigation for the first twelve months. The first irrigation should be within 48 hours of root
pruning. They should be deep watered every two to four weeks during the summer and once a month
during the winter (adjust accordingly with rainfall). One irrigation cycle should thoroughly soak the
root zones of the trees to a depth of 3 feet. The soil should dry out between watering; avoid keeping a
consistently wet soil. Designate one person to be responsible for irrigating (deep watering) the trees.
Check soil moisture with a soil probe before irrigating. Irrigation is best accomplished by installing a
temporary above ground micro-spray system that will distribute water slowly (to avoid runoff) and
evenly throughout the fenced protection zone but never soaking the area located within 6- feet of the
tree trunk, especially during warmer months.
Pruning: Do not prune any of the trees until all construction is completed. This will help protect the
tree canopies from damage. All pruning shall be completed under the direction of an ISA Certified
Arborist and using ISA guidelines. Only dead wood shall be removed from tree canopies.
Washing: During construction in summer and autumn months, wash foliage of trees adjacent to the
construction sites with a strong water stream every two weeks in early hours before 10:00 a.m. to
control mite and insect populations.
Inspection: An ISA Certified Arborist shall inspect the impacted preserved trees on a monthly basis
during construction. A report comparing tree health and condition to the original, pre-construction
baseline shall be submitted following each inspection. Photographs of representative trees are to be
included in the report on a minimum annual basis.
Maintenance After Construction
Once construction is complete the fencing may be removed and the following measures performed to
sustain and enhance the vigor of the preserved trees.
Mulch: Provide a 4-inch mulch layer under the canopy of trees. Mulch should include clean, organic
mulch that will provide long-term soil conditioning, soil moisture retention, and soil temperature control.
Pruning: The trees will not require regular pruning. Pruning should only be done to maintain
clearance and remove broken, dead or diseased branches. Pruning shall only take place following a
recommendation by an ISA Certified Arborist and performed under the supervision of an ISA
Certified Arborist. No more than 20% of the canopy shall be removed at any one time. All pruning
shall conform to International Society of Arboriculture standards.
Tree Protection Measures Page 3
Watering: The natural trees that are not disturbed should not require regular irrigation, other than the
twelve months following substantial root pruning. However, soil probing will be necessary to
accurately monitor moisture levels. Especially in years with low winter rainfall, supplemental
irrigation for the trees that sustained root pruning and any newly planted trees may be necessary. The
trees should be irrigated only during the winter and spring months.
Watering Adjacent Plant Material: All plants near the trees shall be compatible with water
requirements of said trees. The surrounding plants should be watered infrequently with deep soaks
and allowed to dry out in-between, rather than frequent light irrigation. The soil shall not be allowed
to become saturated or stay continually wet. Irrigation spray shall not hit the trunk of any tree. A 60-
inch dry-zone shall be maintained around all tree trunks. An above ground micro-spray irrigation
system is recommended over typical underground pop-up sprays.
Washing: Periodic washing of the foliage is recommended during construction but no more than once
every two weeks. Washing should include the upper and lower leaf surfaces and the tree bark. This
should continue beyond the construction period at a less frequent rate with a high-powered hose only
in the early morning hours. Washing will help control dirt/dust buildup that can lead to mite and
insect infestations.
Spraying: If the trees are maintained in a healthy state, regular spraying for insect or disease control
should not be necessary. If a problem does develop, an ISA Certified Arborist should be consulted;
the trees may require application of insecticides to prevent the intrusion of bark-boring beetles and
other invading pests. All chemical spraying should be performed by a licensed applicator under the
direction of a licensed pest control advisor.
Inspection: All trees that were impacted during construction within the tree protection zone should be
monitored by an ISA Certified Arborist for the first five years after construction completion. The
Arborist shall submit an annual report, photograph each tree and compare tree health and condition to
the original, pre-construction baseline.
