Summary
Sierra Gate Center is a construction project in Fontana, California. As per Fontana
building code, a tree preservation ordinance requires an inventory of existing trees on
the site to be performed by an Arborist. Certified by the International Society of
Arboriculture.
I was asked to visit the site, inspect the trees, collect the required information to analyze
and produce a condition and inventory report. The city of Fontana preservation
ordinance defines the appropriate number of replacement trees to mitigate the loss
taken in this development project. My report summarizes the required replacement
trees.
There are 49 trees on this parcel. Of the 49 trees, there are eight different genera and
11 different species. This report details the trees' size and condition on-site and
provides a mitigation plan as per the preservation requirements in the city preservation
ordinance.
There is a total of 156 replacement trees required. Of the 156 replacement trees
required, one tree required will be a 48- inch box. Twenty-eight (28) trees of 36-inch
box size, 120 trees 24- inch box size, and seven (7) #15-gallon size also are required.
Background
North Gate Real Estate is planning a construction project called Sierra Gate Center at
the old Rock Honda Site in Fontana, California. The site is north of San Bernardino Ave
and east of Sierra Ave. Under Article III -the city of Fontana Preservation of Heritage,
Significant, and Specimen Trees Ordinance No. 1126 § 1, 8-16-94 requires an
inventory of all existing trees on the proposed construction site. The Purpose within the
city building regulations is to preserve any trees defined as Heritage, Significant, and
Specimen trees.
It is my understanding within the new construction plans for Northgate Market and
surrounding shops, the builder's agent will provide a brand-new landscape plan. The
existing trees are not desired for retention or relocation, and the existing trees will be
mitigated as required by the said city building code.
Assignment
Northgate Real Estate asked that I provide a tree Inventory and condition report for The
Sierra Gate Center proposed construction project. My scope of work is to:
• Review the City of Fontan tree preservation ordinance
• Visit the site to clarify boundaries and trees in question
• create a site map showing the location of all existing trees in inventory.
• tag each tree with an identification number tag.
• measure and record the diameter of all trees.
• photograph each tree.
• assess and record the condition of all trees.

Once the inventory is complete, all the information from species, size, and condition will
be analyzed and used to mitigate the environmental impact by providing other
replacement trees as per Ordinance No. 1126.
Observations
There are no Heritage, Specimen, or Windrow1 Significant or protected trees on this
parcel. Also, no state, federal or other protected trees. Appendix E A Photo Inventory of
Tree #s 1-49 contains observations and conditions. Appendix D summarizes the
conditions and tree replacement requirements.
Under Ordinance No. 1126 § 1, 8-16-94 Section 28-67 Tables III and IV are used to
replace what is called Other Trees. Trees under and over 7 inches in diameter have
different replacement requirements. Section III and IV are included and defined in this
report.
Sections of this report are used to organize the data required and are found in the
following appendices.
• Appendix A - Site Map
A site map of the parcel that shows the location of all trees.
• Appendix B - Master Species List
provides a count of all the different species.
• Appendix C - Fontana Protected Tree List
• Appendix D - Mitigation Requirements
a separate list of all 49 species and a list of the required replacement trees.
• Appendix E - Photo Inventory of Tree #s 1-49
a photo record of all the trees on-site with detailed photos of the current conditions.
Each tree in the inventory has a numbered identification tag attached to the trunk at
approximately five to six feet from ground level.
Discussion
It is my understanding that the site has been vacant for at least five years. Soil
conditions are dry, compacted, and lack fresh organic amendments. The trees show
signs of water stress as well as structural defects, and pests. Many of the issues are a
result of neglect and pruning practices that do not follow industry standards or best
management practices. Some of the trees are better suited for our climate, drought
conditions, free of pests, and are reflected in the condition rating. The lack of irrigation
and soil conditions have contributed to surface roots and infrastructure damage to
sidewalk, pavement, and planter island curbs.

Only the best quality trees that receive proper regular care, adequate irrigation,
managed soil, and free pests and structural flaws should be selected for retention,
relocation, or transplanting. I understand that the development team wishes to mitigate
tree loss and start fresh with healthy specimens.
The photographic inventory describes the standard industry size of trees by diameter at
breast height (DBH) and each tree's condition in detail on the site. The Mitigation
Requirements identifies the trees by name and number, showing the trees' condition in
percent rating and the required replacement size and number of replacements.
Conclusion
There are 49 trees on this parcel. Of the 49 trees, there are eight different genera and
11 different species. Most trees are poor to fair condition due to neglect, water stress,
poor soil conditions, structural defects, and improper maintenance. The prior
maintenance did not address early training for structural. As a result, there are many
defects.
Tree topping common on this site and is a destructive and harmful pruning practice.
Topping creates weak structure and hazardous conditions, but it also shortens the
useful lifespan of amenity, landscape, shade, and ornamental trees. Furthermore, poor
pruning practices (topping) or failing to follow ISA Best Management Practices create
more frequent maintenance, lowers tree values, and reduces environmental benefits
that benefit the community.
As per the city preservation requirements, there are a total of 156 replacement trees
required. Of the 156 replacement trees required, one tree required will be a 48- inch
box. Twenty-eight (28) trees of 36-inch box size, 120 trees 24- inch box size, and seven
(7) #15-gallon size are required.

Glossary
bulk density – is an indicator of soil compaction. It is calculated as the dry weight of soil divided
by its volume. Bulk density is dependent on soil texture and the densities of soil minerals salt,
salt, and Clay and organic matter particles, as well as their packing arrangement.
Codominant branches/codominant stems: forked branches nearly the same diameter, arising
from a common union and lacking a branch collar; may have included bark
DBH- trunk diameter measured at 4. 5 feet (1.4 m) above soil line in the United States and
some other countries; at 1.3m in the United Kingdom (in forestry applications), Canada, and
other countries; and 1.5 m in UK arboriculture.
Heritage Tree: (1) a tree associated with a place, building, natural feature or event of local,
regional or national historic significance as identified by city council resolution. (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
statue; 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.
Included bark: bark that becomes embedded in the union between branches and trunks or
between codominant stems. Lacks wood connections, resulting in a week structure.
Inventory Report: a report where the inventory data is separated into categories such as
species, size classes, and data or assessments are made of the quantity and quality.
Significant tree-protected trees as defined by the city of Fontana Southern California Black
Walnut, Coast Live Oak, Deodar Cedar, California Sycamore, and London Plane
Soil compaction: compression of soil, often as a result of vehicle or heavy equipment traffic,
that breaks down soil aggregates and reduces soil volume and total poor space, especially
macropore space
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…
Standards: established or widely recognized authority of acceptable performance.
Stem Girdling Root: root that grows tangentially across the stem, causing vascular
constriction.
Tree inventory: a record of the attributes, location and characteristics of individual trees within
a defined geographic area.
Windrow Trees: a Series of trees (minimum of four), usually a variety of eucalyptus, planted in
it closely spaced line or no more than 10 feet apart to provide a windbreak for the protection of
property and or agricultural crops.

Analysis using a Rating System
The rating of HEALTH uses typical school grades of A, B, C, D or F.
“A” = excellent HEALTH, not excessive, but having good foliage color, leaf size, canopy
density, and twig elongation. “B” = good health, not excessive, having good foliage color,
average leaf size and density, and twig elongation. “C” = fair health, little or no dieback, fair leaf
color, size and density, adequate to continued life.
“D” = poor health, some dieback or poor leaf color, size and/or density, presently declining, but
recoverable.
“F” = dead or dying, with little or no chance of recovery.
The rating of STRUCTURE also uses typical school grades of A, B, C, D or F.
“A” = excellent STRUCTURE, ideal for the species, little or no risk of failure.
“B” = good structure, not more than minor defects in attachment, limb taper or length and no
significant decay. “C” = fair structure, adequate branch attachment, taper, no significant decay,
but correctible defects.
“D” = poor structure, some defects or decay, but acceptable risk level, with corrective pruning
“F” = hazardous and likely to drop limbs or topple, not correctible.
The trees were measured by their trunk diameter at 4.5 feet above grade (DBH – diameter at
breast height). DBH measurements were made using a Forestry Supplies Tree Diameter Tape.
Multi trunk trees are converted to diameter using a cross-section area technique as described
by the Council of Tree and Landscape Appraisers (CTLA) Guide for Plant Appraisal 9th Edition.
The condition percent was reconciled (cross checked) using a random sample and compared
using the CTLA 32-point system.
Abbreviations (when used)
1s = one-sided
Cod = codominant
Cr = crowded limbs, roots or canopies
Db = dieback
DBH = trunk diameter at 4.5 feet above grade.
Dk = decay DL=dogleg
Epi = epicormic shoots
Hd = headed
Inc = included bark
Inj = injury (Tinj=trunk injury, Binj=basal injury)
2long = excessive limb length Lt = lion tailed OP = over pruned
RF = root flare, aka root crown Sh = shallow rooted.
Sp = sparse
TD = tear down
TO = tear out
Top’d = topped
