Biological Resources Technical Memorandum
14386.05 1 OCTOBER 2022
October 27, 2022
Subject: Biological Resources Technical Memorandum for the Fontana Apartments Project Located in the City
of Fontana, San Bernardino County, California
Dear Mr. Samnet,
This biological resources technical memorandum documents the existing biological conditions for the
approximately 11.7-acre subject property located at Assessor Parcel Numbers (APNs): 025-117-119, -25-132-117,
-118, -119, -120, -121, -122, -123, -124, -125, -126, -127, -135, in the city of Fontana, San Bernardino County,
California. This report evaluates the potential for special-status biological resources to occur on the project site
based on the existing conditions observed during a biological reconnaissance and includes a discussion of
potential impacts on biological resources due to project implementation. Potential project-related impacts will
include recommendations to avoid or reduce impacts below a level of significance under CEQA.
Project Location
The project site is bound by Cypress Avenue to the west, Valley Boulevard to the north, Interstate 10 to the south,
and Juniper Avenue to the east (Figure 1: Project Site). The project site is specifically located on a relatively flat,
primarily undeveloped area mapped within The San Bernardino Principal Meridian, in Section 19 of Township 1
South Range 5 West of the Fontana, California 7.5-minute U.S. Geological Survey (USGS) topographic quadrangle
(USGS 2022). For the purpose of this report, the area investigated included the entire 11.7-acre project site plus a
100-foot buffer around the project site boundary, for a total of approximately 20.3 acres (study area). The study
area for the proposed project accounts for both on-site and off-site biological resources that may be impacted by
the proposed project.
Project Description
The project includes construction of a 437-unit apartment complex and ancillary structures on an approximately
11.7-acre property that will be entirely developed by the project. In addition to the apartments, the project would
include landscaping areas as well as surface parking for resident vehicles.

Methods
Literature Review
To evaluate the natural resources previously documented and potentially occurring within the study area,
literature searches and database reviews were conducted by Dudek’s biologists. The database review included
the most recent versions of the California Natural Diversity Database (CNDDB) and special-status species lists
(CDFW 2022a-2022e), and the California Native Plant Society’s (CNPS) Inventory of Rare and Endangered Plants
(CNPS 2022). These databases were reviewed to identify sensitive biological resources present or potentially
present for the Fontana, California USGS 7.5-minute quadrangle on which the study area is located, and the eight
surrounding quadrangles (Guasti, Cucamonga Peak, Devore, San Bernardino North, San Bernardino South,
Corona North, Riverside West, and Riverside East).
Potential and/or historic drainages and aquatic features were investigated based on a review of USGS topographic
maps (1:24,000 scale) aerial photographs, the U.S. Fish and Wildlife Service (USFWS) National Wetland Inventory
(NWI) database (USFWS 2022a), and the Natural Resource Conservation Service’s (NRCS) Web Soil Survey (USDA
2020a).
Soil Survey Review
Dudek reviewed the U.S. Department of Agriculture’s National Resource Conservation Service database to
determine soil characteristics on the study area. According to the NRCS Web Soil Survey (USDA 2022a), the study
area occurs within the San Bernardino County Southwestern Part (CA677). Tujunga loamy sand, 0 to 5 percent
slopes, is mapped within the entire study area (Figure 2: Biological Resources Map). Soils in the Tujunga series
consist of mixed, thermic Typic Xerospamments. Tujunga soils are found on alluvial fans and floodplains at
elevations of 6 to 2,000 feet above sea level. These soils are somewhat excessively drained with negligible to low
runoff and high saturated hydraulic conductivity. Tujunga soils are extensively disturbed throughout the central
and southern coastal plains and valleys of California. Additionally, no Delhi sands are mapped or present within
the study area.
National Wetlands Inventory Review
A formal delineation of jurisdictional waters and wetlands was not conducted on the survey area because after an
assessment of all potentially jurisdictional waters and wetlands during the biological reconnaissance, Dudek’s
biologist determined there are no natural drainages or wetland areas within the survey area that could potentially
be regulated. During the biological reconnaissance all potentially jurisdictional drainages were assessed for their
potential to be regulated under the CWA and California Fish and Game Code Section 1600 et seq. Additionally, a
desktop analysis of hydrological watershed data and mapped wetland resources from the National Wetland
Inventory was conducted prior to the reconnaissance to determine if any historic blue-line streams, watercourses,
or wetlands were mapped on the survey area (USFWS 2022a). Although a formal jurisdictional delineation was not
conducted, the assessment still followed regulatory methods and definitions of potentially regulated aquatic
resources.
Pursuant to the CWA, ACOE, and RWQCB, jurisdictional areas include those supporting all three wetlands criteria
described in the ACOE manual: hydric soils, hydrology, and hydrophytic vegetation. The ACOE/Environmental
FONTANA APARTMENTS PROJECT / BIOLOGICAL RESOURCES TECHNICAL REPORT
14386.05 3 OCTOBER 2022
Protection Agency Rapanos Guidance states that ACOE will regulate traditional navigable “waters of the United
States,” adjacent wetlands, and relatively permanent waters tributary to traditional navigable waters, and
adjacent wetlands if there is a significant nexus from the site. Areas regulated by RWQCB/CDFW are generally
coincident with areas regulated by ACOE, but can also include isolated features that have evidence of surface
water inundation pursuant to the state Porter–Cologne Act. These areas generally support at least one of the
three ACOE wetlands indicators, but are considered isolated through the lack of surface water
hydrology/connectivity downstream.
Features that convey or hold water are regulated by multiple agencies. Federal, state, and local agencies have
different definitions and terminology for these types of features. Water-dependent resources regulated by ACOE,
RWQCB, CDFW, and the County of Riverside are collectively referred to as “jurisdictional aquatic resources”
herein. Terminology used in this document to distinguish each jurisdictional aquatic resource according to the
agency that regulates the resource is as follows:
• ACOE and RWQCB: “Wetland” and “non-wetland waters.” Wetland waters of the United States and non-
wetland waters of the United States are subject to regulation by ACOE and RWQCB, pursuant to the CWA.
Within the biological survey area, ACOE waters of the United States and wetlands, and RWQCB waters of
the United States and wetlands overlap, and therefore are combined under one term: “non-wetland
waters” or “wetlands.”
• CDFW: “Riparian areas” and “streambeds.” Lakes, rivers, and streambeds, including any associated
riparian habitat, are subject to regulation by CDFW, pursuant to Section 1600 et seq. of the California
Fish and Game Code. Within the biological survey area, CDFW streambeds are synonymous with ACOE
and RWQCB non-wetland waters. CDFW riparian areas are not synonymous with ACOE or RWQCB
wetlands because these areas lacked all three federal wetland parameters (hydrophytic vegetation,
hydric soils, and hydrology).
Biological Reconnaissance
Dudek biologist Kimberly Narel conducted a general biological reconnaissance of the study area on June 20,
2022. The survey was conducted from 0900 - 1030 a.m.; weather conditions were favorable with 0% cloud cover,
wind speeds from 0-8 miles per hour, and a temperature range of 78° - 84° Fahrenheit (°F). All native and
naturalized plant species encountered in the study area were identified and recorded. The potential for special-
status plant and wildlife species to occur within the study area was evaluated based on the vegetation
communities and soils present. Dudek used CDFW’s Protocols for Surveying and Evaluating Impacts to Special
Status Native Plant Populations and Natural Communities (CDFW 2018) and List of Vegetation Alliances and
Associates (CDFW 2019), also referred to as the Natural Communities List, to map the entire study area.
Vegetation communities and land covers were delineated to the vegetation alliance level, and where appropriate
the association level, based on the Manual of California Vegetation (Sawyer, Keeler-Wolf, and Evans 2009). Some
modifications, such as the Preliminary Descriptions of the Terrestrial Natural Communities of California (Holland
1986, and Oberbauer et al. 2008), were incorporated to accommodate the lack of conformity of the observed
communities to those included in these references.
Latin and common names for plant species with a California Rare Plant Rank (CRPR) follow the CNPS Inventory of
Rare and Endangered Plants (CNPS 2020). For plant species without a CRPR, Latin names follow the Jepson
Interchange List of Currently Accepted Names of Native and Naturalized Plants of California (Jepson Flora Project
FONTANA APARTMENTS PROJECT / BIOLOGICAL RESOURCES TECHNICAL REPORT
14386.05 4 OCTOBER 2022
2020), and common names follow the Unites States Department of Agriculture’s Natural Resources Conservation
Service Plants Database (USDA 2020b). Latin and common names of animals follow Crother (2008) for reptiles
and amphibians, American Ornithologist’s Union for birds (AOU 2016), Wilson and Reeder (2005) for mammals,
North American Butterfly Association (NABA 2016), and Moyle (2002) for fish.
Dudek also conducted an assessment for the presence of waters or wetlands potentially subject to regulatory
agency jurisdiction, including searching for the presence or drainage features and topographic features and soils
that could support standing water. However, a formal wetland delineation was not conducted as part of the
biological reconnaissance.
Results
Study Area Description
Based on the database reviews and biological reconnaissance, the study area is characterized as predominantly
undeveloped non-native grassland with disturbed habitat. Vegetation currently present on the study area is
dominated by non-native grassland with evidence of past agricultural tilling and/or discing. Scattered ornamental
vegetation occurs in the center of the study area and borders portions of the northern and southern project site
boundaries. Disturbed habitat occurs on the southeastern portion of the study area and is characterized by a
concrete foundation with compacted gravel used as a semi-truck offloading and rest area. Dirt pedestrian access
paths bisect the study area from Valley Boulevard southeast to the concrete foundation. Representative
photographs of the study area are included in Appendix B, Site Photo Log. The entire study area has been
previously graded and compacted and is relatively flat, ranging in elevation from approximately 1,110 feet to
1,120 feet above mean sea level (AMSL). The western portion of the study area has been previously tilled and/or
disced. The study area occurs in an urban setting and is surrounded by a mixture of residential and commercial
development and paved streets.
Vegetation Communities and Land Covers
Three vegetation communities and/or land cover types were observed on the study area during the biological
reconnaissance: non-native grassland, disturbed habitat, and developed land. No natural or native vegetation
communities were observed on the study area during the biological reconnaissance (Figure 2: Biological
Resources Map). There are no sensitive vegetation communities within the study area. No exposed soils were
observed within the study area that have not been heavily altered and compacted for prior development or
existing semi-truck parking. Any natural vegetation communities that historically occurred on the study area have
been removed during previous grading of the project site and immediate surroundings. Evidence of tilling and/or
discing was observed on the western portion of the project site. The three vegetation communities and/or land
covers observed on the study area are described in further detail herein.
Non-Natural and Unvegetated Land Covers
Non-Native Grassland. The non-native grassland mapping unit is not recognized by the Natural Communities List
(CDFW 2020e) but is described by Oberbauer et al. (2008). Non-native grassland is the dominant vegetation type
on the study area. It consists of ruderal forbs, spurges, and herbaceous annual and perennial species.
Characteristic species of this community observed within the study area include: bromes (Bromus diandrus, B.
tectorum), wall barley (Hordeum murinum), Bermuda grass (Cynodon dactylon), spotted spurge (Euphorbia
FONTANA APARTMENTS PROJECT / BIOLOGICAL RESOURCES TECHNICAL REPORT
14386.05 5 OCTOBER 2022
maculata), and common stork’s bill (Erodium cicutareum), with London rocket (Sysimbrium irio), shortpod
mustard (Hirschfeldia incana), and southern Russian thistle (Salsola tragus) interspersed throughout the shrub
layer. Native herbaceous annual plants including horseweed (Erigeron canadensis), western ragweed (Ambrosia
psilostachya), and flatspine bur ragweed (Ambrosia acanthicarpa) occur sporadically in the southern portion of
the non-native grassland along with common fiddleneck (Amsinckia intermedia var. intermedia), telegraph weed
(Heterotheca grandiflora), and Wright’s cudweed (Pseudognaphalium microcephalum). Sacred datura (Datura
wrightii), a native shrub, occurs in patches of the non-native grassland along with ornamental vegetation in the
center of the project site. A total of approximately 10.2 acres of non-native grassland occurs within the study area.
Disturbed Habitat. The disturbed mapping unit is not recognized by the Natural Communities List (CDFW 2020e)
but is described by Oberbauer et al. (2008). Disturbed land typically refers to areas that lack vegetation but still
retain a previous surface, or that are dominated by sparse cover or ruderal vegetation. Approximately 1.14 acres
disturbed habitat on the study area consists of dirt pedestrian access paths leading to a square patch of concrete
foundation with compacted gravel on the southeastern portion of the project site. This area is used for semi-truck
parking and as a rest stop. The concrete foundation is heavily cracked, with ruderal grasses and weeds growing
sporadically through the gravel before transitioning to surrounding non-native grassland on the study area. In
addition, a dirt pedestrian access path follows the northern project site boundary along Valley Boulevard, and
contains a line of ornamental trees.
Urban/Developed Land. The urban and developed mapping unit is not recognized by the Natural Communities List
(CDFW 2020e) but is described in Oberbauer et al. (2008). Developed land typically includes areas that have
been constructed upon and do not contain any naturally occurring vegetation. These areas are generally
characterized as graded land with asphalt and concrete placed upon it. Developed areas mapped for the study
area include the existing paved, graded, compacted, and cleared portions of the project site. A total of
approximately 8.94 acres of urban and developed land occurs within the study area, consisting of surrounding
commercial and urban development, Valley Boulevard, and Juniper Avenue.
Ornamental trees and shrubs observed on the southern and northern project site boundaries are associated with
adjacent paved roads as well as residential and commercial development. Ornamental plantings on the study
area did not meet the minimum mapping unit threshold to include as a separate mapped vegetation community.
Characteristic ornamental species observed include Eucalyptus sp., Japanese honeysuckle (Lonicera japonica),
golden wattle (Acacia pycnantha), Chinaberry (Melia azedarach), Korean mulberry (Morus indica), common olive
(Olea europaea), tree of heaven (Ailanthus altissima), Mediterranean cypress (Cupressus sempervirens), and
Lantana (Lantana camara). One native tree, western sycamore (Platanus racemosa), occurs within the
ornamental vegetation bordering the southeastern project site boundary. In addition, a row of Eucalyptus trees
follows a chain-link fence that bisects the two undeveloped parcels on the project site and continues along a
portion of the northern project site boundary, parallel to Valley Boulevard.
Table 1 provides a summary of each land cover’s extent within the study area.

As no sensitive or native vegetation communities are present on the study area, no significant direct or indirect
impacts to sensitive vegetation communities will occur from vegetation clearing for construction of the proposed
project. Direct impacts to sensitive vegetation communities would be considered significant absent mitigation
under CEQA.
Wildlife
The study area consists of non-native grassland and ornamental vegetation that provides potentially suitable
habitat for wildlife species that occur in urbanized settings. Wildlife use and species diversity was limited during
the biological reconnaissance. Species observed or detected included mourning dove (Zenaida macroura), house
finch (Carpodacus medicanus), house sparrow (Passer domesticus), American crow (Corvus brachyrhynchos),
California ground squirrel (Otospermophilus beecheyi), and western fence lizard (Sceloporus occidentalis). No
amphibian or aquatic species were observed within the study area. The complete list of plant and wildlife species
observed within the study area is included in Appendix A, Species Compendium.
No active bird nests were observed during the field visit; however, ornamental trees within the study area could
support nesting migratory birds, particularly along the northern and southern project site boundaries. Two small
animal burrows were observed within the center of the study area adjacent to a disturbed dirt path. However, the
shallow depth, diameter at less than four inches, and evidence of disuse (detritus, webbing, partially infilled)
observed indicates the burros are inactive. Further, the size and shape of the burrows taper inward and are not
suitable for burrowing owl. No indirect evidence of burrowing owl activity (pellets, whitewash, insect carapaces)
was observed on the study area. Small animal burrows may be used by a variety of species, including rodents and
reptiles that are accustomed to urban environments, such as California ground squirrel and western fence lizard.
Details regarding the potential for special status species to occur within the study area are discussed below.
Special-Status Species
Special-Status Plant Species
Special-status plant species include those listed, or candidate for listing, as threatened or endangered by USFWS
or CDFW, or species identified as rare by CNPS (particularly CRPR 1A – Presumed extinct in California; CRPR 1-B –
Rare, threatened, or endangered throughout its range; and CRPR 2 – Rare or Endangered in California, more
common elsewhere). A total of 82 special-status plant species were reported in the CNDDB, USFWS, and CNPS
databases as occurring within the vicinity of the study area (CNPS 2022). Appendix C: Plant Species with a
Potential to Occur on the Study Area, includes the species lists provided from these database searches that were
evaluated as part of this assessment. For each species evaluated, a determination was made regarding the
potential for the species to occur on site based on information gathered during the field reconnaissance, including
the location of the site, habitats present, current site conditions, and past and present land use.
Of the 82 special-status plant species listed in the CNDDB, CNPS, and USFWS databases as occurring in the
vicinity of the study area, 68 species were determined to have no potential to occur within the study area based
FONTANA APARTMENTS PROJECT / BIOLOGICAL RESOURCES TECHNICAL REPORT
14386.05 7 OCTOBER 2022
on an evaluation of species ranges/elevation and known habitat preferences. No special-status plant species
were determined to have a moderate or high potential to occur on the study area. However, 12 special-status
species were determined to have a low potential to occur due to limited suitable habitat within the study area
(Appendix C: Special-Status Plant Species with a Potential to Occur on the Study Area). Of those, two are listed as
endangered by FESA and/or CESA: San Diego ambrosia (Ambrosia pumila), and thread-leaved brodiaea (Brodiaea
filifolia). While suitable grassland capable of supporting these two species are present onsite, the study area has
been graded and compacted in the past, with refuse from pedestrian traffic, and evidence of recent tilling and/or
discing on the western portion of the project site, making for poor growth conditions. In addition, no wetlands,
vernal pools, or other mesic habitat capable of supporting thread-leaved brodiaea and San Diego ambrosia were
observed on the study area.
Due to the on-going disturbances from semi-truck offloading and pedestrian traffic that currently occur within the
study area, the limited grassland habitat onsite is of low quality. As such, protocol-level rare plant surveys were not
conducted. The remaining special-status plant species determined to have a low potential to occur are on the
study area are not listed by FESA or CESA but are identified as rare by CNPS, and are not discussed in this report
further. The complete list of plant species evaluated with a determination of their potential to occur on the study
area is provided in Appendix C.
Therefore, vegetation clearing for construction of the proposed project is anticipated to have no significant direct
or indirect impact to special-status plant species.
Special-Status Wildlife Species
Special-status wildlife include those listed, or candidates for listing, as threatened or endangered by USFWS or
CDFW, or designated as a Species of Special Concern by CDFW (CDFW 2022 b, c). No special-status wildlife
species were detected onsite during the biological reconnaissance. A total of 64 special-status wildlife species
were reported in the CNDDB and USFWS databases as occurring in the vicinity of the study area. Appendix D:
Special-Status Wildlife Species with a Potential to Occur on the Study Area, summarizes the special-status wildlife
species that were included in these databases and evaluated as part of this assessment. For each species
evaluated, a determination was made regarding the potential use of the site based on information gathering
during the field reconnaissance, known habitat preferences, and knowledge of their relative distributions in the
area.
Of the 64 special-status wildlife species listed in the CNDDB and USFWS databases as occurring in the vicinity of
the study area, 50 species were determined to have no potential to occur based on an evaluation of species
ranges/elevation and known habitat preferences. No special-status species were determined to have a moderate
or high potential to occur on the study area. However, 14 special-status species were determined to have a low
potential to occur due to limited suitable habitat within the study area. None of these species were observed
during the biological reconnaissance. In addition, it is unlikely that special-status mammals or reptiles will occupy
the low-quality grassland on the study area due to compacted soils from prior grading onsite that make for poor
burrowing conditions. No evidence of burrow activity was observed on the study area, including the western
portion where prior tilling and/or discing created loose, upturned soil. The few inactive animal burrows observed
in the center of the project site were infilled, shallow, and not large enough in diameter to support burrowing owl.
However, ornamental shrubs and trees bordering the project site boundary could support nesting special-status
birds and migratory bird species protected by the Migratory Bird Treaty Act (MBTA).
FONTANA APARTMENTS PROJECT / BIOLOGICAL RESOURCES TECHNICAL REPORT
14386.05 8 OCTOBER 2022
Note that Delhi sands flower-loving fly (Rhaphiomidas terminatus abdominalis) is a special-status species of
concern in the area due to nearby Delhi fine sands. These species will be further discussed below. The remaining
species with no potential to occur or low potential to occur are omitted from further discussion in this report due
to limited low-quality habitat onsite. The complete list of wildlife species evaluated with a potential to occur on the
study area is provided in Appendix D.
Delhi Sands Flower-Loving Fly Habitat
There are no historically mapped areas of Delhi sand within the study area. Delhi sand or any remnants of
previously sandy areas were not observed during the survey, and the nearest occurrence of Delhi fine sand is
approximately 0.7 miles southwest of the project site (USDA 2022a). However, there are onsite (within entire
Fontana USGS 24k quadrant) occurrence records of Delhi sands flower loving fly, the most recent from 2013
(CDFW 2022a). The Delhi sands flower-loving fly typically occurs in areas with Delhi sands present but has been
found in other sandy habitats; however, the study area is devoid of native vegetation and there are no exposed
soils on site that have not been compacted and heavily altered. While one of the two host plants most commonly
associated with the species, telegraph weed (Heterotheca grandiflora) was observed on the study area, the other,
California buckwheat (Eriogonum fasciculatum), was not observed onsite during the biological reconnaissance.
Additionally, no sand dune habitat for this species occurs on the study area, and as such, there is no potential for
the Delhi sands flower-loving fly to occur.
Given the low-quality, fragmented, and disturbed habitat on the project site, and location within an urban area,
there is no moderate or high potential for special-status species to occur on the study area, and as such, no
protocol-level focused special-status species surveys were conducted. Vegetation clearing for construction of the
proposed project is anticipated to have no significant direct or indirect impact on special-status species.
Jurisdictional Waters and Wetlands
No formal jurisdictional wetland delineation was conducted on the study area. However, a preliminary assessment
of potential jurisdictional waters on the study area during the biological reconnaissance determined there are no
waterways or drainages within the project site that would be subjected to regulatory agency jurisdiction.
Additionally, no wetlands or riparian habitats were observed on the project site. Lastly, no soils mapped on the
study area are considered hydric. As currently designed, vegetation clearing and construction of the proposed
project would not directly impact jurisdictional waters and wetlands. No significant direct impacts to jurisdictional
waters and wetlands are anticipated to occur as a result of construction of the proposed project.
However, the NWI dataset depicts a mapped channelized concrete flood channel within the southern portion of
the study area buffer, approximately 60 feet south of the project site boundary footprint (Figure 2: Biological
Resources Map) (USFWS 2022a). The Cowardin classification code of this NWI-mapped flood channel is R5UBFx
(Riverine system, Unknown Perennial subsystem, Unconsolidated Bottom, Semi-permanently Flooded, Excavated).
This flood control channel flows east-west into the West Fontana Channel, a tributary to San Sevaine Channel and
ultimately the Santa Ana River. Although proposed construction activities are not anticipated to directly impact or
encroach into this concrete flood channel, indirect impacts (i.e., stormwater runoff, chemical spills, sedimentation,
dust) could occur. Indirect project impacts to mapped jurisdictional waters and wetlands are considered
significant absent mitigation and/or permitting from ACOE, RWQCB, and/or CDFW.

14386.05 9 OCTOBER 2022
Wildlife Corridors and Habitat Linkages
Wildlife corridors are linear features that connect large patches of natural open space and provide avenues for the
migration of animals. Wildlife corridors contribute to population viability by assuring continual exchange of genes
between populations, providing access to adjacent habitat areas for foraging and mating, and providing routes for
recolonization of habitat after local extirpation or ecological catastrophe (e.g., fires).
Habitat linkages are small patches that join larger blocks of habitat and help reduce the adverse effects of habitat
fragmentation. Habitat linkages provide a potential route for gene flow and long-term dispersal of plants and
animals and may serve as primary habitat for smaller animals such as reptiles and amphibians. Habitat linkages
may be continuous habitat or discrete habitat islands that function as steppingstones for dispersal.
The entire study area is surrounded by development and no portions of the study area function as a wildlife
corridor or linkage that connect to larger habitat areas in the region, such as the Santa Ana River further south.
The study area is not mapped as an important wildlife corridor or linkage and occurs on a fragmented, low quality,
previously disturbed (graded and disced/tilled) area surrounded by residential and commercial development, with
Interstate 10 immediately to the south of the southernmost project site boundary. On a local scale, the study area
may function as a linkage for small to medium-sized mammals and reptiles to use the project site as a corridor, to
travel locally to fragmented undeveloped parcels to the south and northeast. However, Interstate 10 is a paved
road with consistent high traffic volume that would significantly impede local wildlife movement. As such, no direct
or indirect impacts to wildlife corridors and habitat linkages would result from vegetation clearing for construction
of the proposed project on the study area. Proposed project development on the study area would have no
significant impact to wildlife corridors and habitat linkages.
Local Policies and Ordinances
The City of Fontana’s Tree Preservation and Protection Ordinance (Chapter 28, Article III of the City’s Code of
Ordinances) regulates the planting, maintenance, preservation, and removal of heritage, significant, and
specimen tree species within the city (City of Fontana 2016). A heritage tree means any tree which is: 1) 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; 2) is representative of a significant period of
the city’s growth or development (windrow tree, European olive tree; 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
their designee because of size, condition, location, or aesthetic qualities. Significant trees are defined as any of
the following species: southern California black walnut (Juglans californica), coast live oak (Quercus agrifolia),
Deodora cedar (Cedrus deodora), California sycamore (Platanus racemosa), and London plane (Platanus
acerifolia). A specimen tree is defined as a mature tree which is not a heritage or significant tree that is an
excellent example of its species in structure and aesthetics and warrants preservation, relocation, or replacement
(City of Fontana 2016).
The study area contains heritage and significant trees protected by the City of Fontana Code of Ordinances
(Section 28, Article III, City of Fontana 2016). Specifically, one significant tree, a western sycamore, occurs on the
southeastern project site boundary, adjacent to Juniper Avenue. In addition, one heritage tree, a European olive, is
interspersed with other ornamental vegetation and a row of Eucalyptus trees along the southern project site
boundary, associated with adjacent commercial and residential development. Scattered Eucalyptus trees were
FONTANA APARTMENTS PROJECT / BIOLOGICAL RESOURCES TECHNICAL REPORT
14386.05 10 OCTOBER 2022
observed along a chain-link fence that bisects the disced/tilled soils on the western side of the project site from
the previously graded and compacted soil on the central and eastern portions of the project site. A third row of
Eucalyptus trees occurs along the northern project site boundary parallel to Valley Boulevard. These may be
considered Eucalyptus windrows. A windrow is defined as a series of trees (minimum of four), usually a variety of
Eucalyptus, planted in a closely spaced line no more than 10 feet apart to provide a windbreak for the protection
of property and/or agricultural crops (City of Fontana 2016). The rows of Eucalyptus trees on the study area, if
considered windrows, are also considered heritage trees.
Direct and indirect impacts to protected trees would occur from vegetation clearing for construction of the
proposed project. Given that compliance with the City’s Tree Preservation and Protection Ordinance is required,
construction of the proposed project would not conflict with local policies or ordinances protecting biological
resources, such as a tree preservation policy or ordinance.
Regional Resource Planning Context
The study area does not occur within any approved, in process, or implementing Habitat Conservation Plan (HCP)
or Natural Community Conservation Plans (NCCP) for local or regional protection of species. As such, construction
of the proposed project will not result in direct or indirect impacts to regional habitat conservation plans.
Recommendations
This section addresses the anticipated impacts (direct, indirect, and cumulative) to biological resources that
would result from implementation of the proposed project. The following recommendations would reduce any
proposed or potential impacts to the thresholds provided in the California Environmental Quality Act Guidelines
Section 15064(b) and Appendix G Environmental Checklist to a less than significant level. Recommendations are
included for the evaluation of the project’s impacts on potentially affected resources such as nesting birds and
local policies and ordinances. No focused surveys for special-status species are recommended as the study area
consists of fragmented, low-quality habitat with no moderate or high potential for special-status plants and wildlife
to persist.
Nesting Birds
The eucalyptus trees and other ornamental plantings located within the study area may provide suitable nesting,
roosting and foraging habitat for various bat and raptor species. As such, avoid construction activities during the
bird nesting season (generally February 1 through August 30) to ensure compliance with the federal Migratory
Bird Treaty Act and California Fish and Game Code Section 3500 et seq. If avoidance of the nesting season is not
feasible, then a pre-construction nesting bird survey should be conducted by a qualified biologist within a
maximum of 3 days prior to the start of construction in areas that could support tree-, shrub-, and ground-nesting
birds to ensure that birds are not engaged in active nesting within 100 feet of the project’s construction limits. If
nesting birds are discovered during the pre-construction survey, then the qualified biologist should identify an
appropriate buffer where no ground-breaking activities are allowed to occur until after the birds have fledged from
the nest. The active nest buffer size depends on the species’ sensitivity to disturbance (typically 500 feet for

FONTANA APARTMENTS PROJECT / BIOLOGICAL RESOURCES TECHNICAL REPORT
14386.05 11 OCTOBER 2022
City of Fontana Tree Preservation and Protection Ordinance
A tree removal permit must first be obtained from the community development department prior to removal of any
heritage or significant tree protected on the study area by the City’s Tree Preservation and Protection Ordinance
(City of Fontana 2016). To ensure compliance with the City’s Tree Preservation and Protection Ordinance and
apply for tree removal permits, a tree inventory is recommended to be conducted by a certified Arborist prior to
project implementation to identify the location, number, species, diameter, and height of all onsite heritage
(including potential Eucalyptus windrows) and significant trees in relation to proposed project improvements. An
Arborist Report should be prepared by the certified arborist, wherein all applicable on-site trees that would be
expected to be removed by the project will be evaluated, and outline replacement procedures for all eligible trees
to be removed from the project site.
Pursuant to the City’s Code of Ordinances, tree replacement is required for potential impacts to significant and
heritage trees on the study area that would be removed by vegetation clearing for construction of the proposed
project. Tree replacement ratio is dependent on overall condition and size of the protected trees onsite. Heritage
and significant tree preservation on the site is preferred to relocation or replacement. 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 Section 28-67(a)(2) of the City of Fontana Code of Ordinances.
