Subject: Arborist Report for First Tamarind II Logistics Project in the City of Fontana, California
(LSA Project No. FRT2202)
Dear Mr. Loubet:
LSA conducted a tree inventory for the First Tamarind II Logistics Project (project). The
approximately 4-acre project site (Assessor’s Parcel Number 0256-011-03 and -04) is southwest of
the intersection of Tamarind Avenue and Tamarind Court in the City of Fontana (City), San
Bernardino County, California (Figure 1, attached). The tree inventory was conducted in accordance
with the City’s tree protection ordinance.1 No trees meeting the ordinance’s definition of a
Significant, Heritage, or Specimen Tree were found on the site.
METHODS
Trees on the site were inventoried on April 1 from 10:00 a.m. to 12:45 p.m. by LSA arborist Stan
Spencer (International Society of Arboriculture [ISA] Certified Arborist WE-9358A), assisted by LSA
biologist Heather Monteleone. All ornamental, fruit, nut, and native trees with trunk diameters of at
least 0.75 inch were inventoried, as well as stump regrowth and dead trees, if any.
The inventory did not include palms under 8 feet tall or weed species, such as tree tobacco
(Nicotiana glauca) and tree of heaven (Ailanthus altissima). Inventoried trees were identified,
assigned a number, mapped, and evaluated by measuring trunk diameter and height and assessing
general condition. The trunk diameter for multi-stem trees was calculated by taking the square root
of the sum of the squared diameters of the individual stems. The inventory and assessment were
conducted in accordance with Section 28-67 of Article III (preservation of Heritage, Significant, and
Specimen Trees) of the Fontana Municipal Code. Trunk diameter was measured at 6 inches above
ground level for trees with trunk diameters of 0.75 to 4 inches, at 12 inches above ground level for
trees with trunk diameters of 5 to 8 inches, and at 54 inches above ground level for trees with trunk
diameters of 9 inches or greater. The height of measurement was lowered if necessary to avoid
branch points. A tree health rating was applied on a scale of 10 to 100 to each tree, taking into
account the species, trunk diameter, height, canopy, and structure.

RESULTS AND DISCUSSION
Figure 1 shows locations of trees and stump regrowth on the proposed project site. Table A provides
tree measurements, ratings, and replacement requirements according to criteria specified in the
City’s ordinance. There are no trees on the site that qualify as Heritage, Significant, or Specimen
Trees. Trees on the site are in generally average to poor condition due to age, drought, and soil
conditions. Replacement is required for all living trees and cut trees with stump regrowth, as
specified in Table A. There are stands of tree tobacco and tree of heaven within in the south-central
portion of the site. These are invasive species, not ornamental trees, and should be eradicated from
the site.
