SUBJECT: Results of a Habitat Assessment for the Fontana 47 Project – City of Fontana, San
Bernardino County, California
Dear Mr. Dille:
Michael Baker International (Michael Baker) is pleased to submit this report to City of Fontana
documenting the results of a habitat assessment for the proposed Fontana 47 Project (project or project site)
located in the City of Fontana, San Bernardino County, California. Michael Baker conducted a thorough
literature review and a field survey to reconfirm existing site conditions and assess the potential for special-
status1 plant and wildlife species that have been documented or that are likely to occur on or within the
immediate vicinity of the project site. Specifically, this report provides a detailed assessment of the
suitability of the on-site habitat to support special-status plant and wildlife species that were identified in
the California Department of Fish and Wildlife (CDFW) California Natural Diversity Database (CNDDB)
RareFind 5 (CDFW 2020a), the CNDDB Biogeographic Information and Observation System (BIOS;
CDFW 2020b), the California Native Plant Society (CNPS) Online Inventory of Rare and Endangered
Plants of California (Online Inventory; CNPS 2020), and other databases as potentially occurring in the
vicinity of the project site.
Project Location
The project site is generally located north of the Interstate 10, east of Interstate 15, south of State Route
210, and west of Interstate 215 in the City of Fontana, San Bernardino County, California. The project site
is depicted in Section 13 of Township 1 South, Range 6 West, on the United States Geological Survey’s
(USGS) Fontana, California 7.5-minute quadrangle. Specifically, the project site is approximately 12.8
acres located to the north of Randall Avenue, to the east of Poplar Avenue, to the south of Merrill Avenue,
and to the west of Catawba Avenue.
1 As used in this report, “special-status” refers to plant and wildlife species that are federally-/State-listed, proposed, or candidates;
plant species that have been designated a California Rare Plant Rank species by the California Native Plant Society; wildlife
species that are designated by the California Department of Fish and Wildlife as Fully Protected, Species of Special Concern, or
Watch List species; and State/locally rare vegetation communities.

Habitat Assessment
Project Description
The project consists of two main components: 1) land use and zoning changes over approximately 12.8
acres, and 2) tentative tract map and design review for the construction of 47 single- family dwellings on 9
acres. The proposed project requires a number of entitlements from the City of Fontana, including:
• General Plan Amendment No. 20-015 – request to change the land use from R-SF to R-M;
• Zone Change No. 20-015 – request to change the zone from R-1 to R-2;
• Tentative Tract Map No. 20358 (TTM20-006) request to subdivide 9 gross acres into 47 single-
family residential lots with private internal streets, street lighting, sewer, water, and perimeter block
wall; and
• Design Review No. 20-028 – request to approve the architectural design and layout of the proposed
housing product.
The project site is approximately 12.8 acres located on the west side of Catawba Avenue at the terminus of
Hibiscus Street, and on the east side of Poplar Street. The project proposes to develop forty-seven (47)
single family residential units with associated road, utility, and water quality management improvements
(refer to Attachment B, Site Plan). At the City’s request, additional parcels have been included into the
scope of the proposed General Plan Amendment and Zone Change. These parcels would undergo the
aforementioned changes but would not be developed into residential units as part of this project.
Methodology
Literature Review
Michael Baker conducted thorough literature reviews and records searches to determine which special-
status biological resources have the potential to occur on or within the general vicinity of the project site.
Previous special-status plant and wildlife species occurrence records within the USGS Cucamonga Peak,
Devore, Fontana, and Guasti, California 7.5-minute quadrangles were determined through a query of the
CNDDB (CDFW 2020a), BIOS (CDFW 2020b), CNPS Online Inventory (CNPS 2020), and the Calflora
Database (Calflora 2020). Current conservation status of species was verified through lists and resources
provided by the CDFW, specifically the Special Animals List (CNDDB 2020c), State and Federally Listed
Endangered and Threatened Animals of California (CNDDB 2020d), Special Vascular Plants, Bryophytes,
and Lichens List (CNDDB 2020e), and State and Federally Listed Endangered, Threatened, and Rare
Plants or California (CNDDB 2020f). In addition, Michael Baker reviewed previously prepared reports,
survey results, and literature, as available, detailing the biological resources previously observed on or
within the vicinity of the project site to gain an understanding of existing site conditions, confirm previous
species observations, and note the extent of any disturbances that have occurred within the project site that
would otherwise limit the distribution of special-status biological resources. Standard field guides and texts
were reviewed for specific habitat requirements of special-status species, as well as the following resources:
• City of Fontana General Plan Update (City of Fontana, 2017);
• Google Earth Pro Historical Aerial Imagery from 1994 to 2020 (Google, Inc. 2020);
• San Bernardino County General Plan (County of San Bernardino, 2007);
• Species Accounts provided by Birds of North America (The Cornell Lab of Ornithology 2020);
• Staff Report on Burrowing Owl Mitigation (CDFW, 2012);
Fontana 47 3

• United States Department of Agriculture, Natural Resource Conservation Service’s (USDA)
Custom Soil Resource Report for San Bernardino County Southwestern Part, California, (USDA
2020); and
• USFWS Critical Habitat Mapper and Environmental Conservation Online System (USFWS
2020b).
Habitat Assessment/Field Survey
Michael Baker biologists Ashley Spencer and Tom Millington conducted a habitat assessment/field survey
on December 29, 2020 to confirm existing site conditions within the project site. Vegetation communities
occurring within the project site were mapped on an aerial photograph and classified in accordance with
the vegetation descriptions provided in A Manual of California Vegetation (MCV; Sawyer et al. 2009) and
cross referenced with the Preliminary Descriptions of the Terrestrial Natural Communities of California
(Holland 1986) for the purposes of evaluating the presence or absence of special-status vegetation
communities identified in the CNDDB records search, which uses the Holland vegetation system. In
addition, site characteristics such as soil condition, topography, hydrology, anthropogenic disturbances,
indicator species, condition of on-site vegetation communities, and the presence of potentially regulated
jurisdictional features were noted. Michael Baker used Geographic Information Systems (GIS) ArcView
software to digitize the mapped vegetation communities and then transferred these data onto an aerial
photograph to further document existing conditions and quantify the acreage of each vegetation community.
Refer to Table 1 below for a summary of the survey dates, timing, surveyors, and weather conditions.

All plant and wildlife species observed, as well as dominant plant species within each vegetation
community, were recorded. Plant species observed during the habitat assessment were identified by visual
characteristics and morphology in the field while unusual and less familiar plant species were photographed
and identified later using taxonomic guides. Plant nomenclature used in this report follows the Jepson Flora
Project (2018) and scientific names are provided immediately following common names of plant species
(first reference only). Wildlife detections were made through aural and visual detection, as well as
observation of sign including scat, trails, tracks, burrows, and nests. Field guides used to assist with
identification of species during the habitat assessment included The Sibley Guide to Birds (Sibley 2014) for
birds, A Field Guide to Western Reptiles and Amphibians (Stebbins 2003) for herpetofauna, Bats of the
United States and Canada (Harvey et al. 2011) for bats, and A Field Guide to Mammals of North America
(Reid 2006). Although common names of wildlife species are well standardized, scientific names are
provided immediately following common names of wildlife species in this report (first reference only). To
the extent possible, nomenclature of birds follows the most recent annual supplement of the American
Ornithological Union’s Checklist of North American Birds (Chesser et al. 2019), nomenclature of
amphibians and reptiles follows Scientific and Standard English Names of Amphibians and Reptiles of
Fontana 47 4
Habitat Assessment
North America North of Mexico, with Comments Regarding Confidence in Our Understanding (Crother
2017), and nomenclature for mammals follows the Revised Checklist of North American Mammals North
of Mexico (Bradley et al. 2014).
Existing Site Conditions
According to the Custom Soil Resource Report for San Bernardino County Southwestern Part, California
(USDA 2020), the project site is underlain by the following soil units: Tujunga loamy sand, 0 to 5 percent
slopes (TuB) and Tujunga gravelly loamy sand, 0 to 9 percent slopes (TvC). The project site ranges in
elevation from approximately 1,188 to 1,202 feet above mean sea level. After a review of Google Earth
historic aerial imagery and results from the field survey, it was determined that the project site is comprised
of existing residential development and disturbed habitat that is subject to routine weed abatement, resulting
in heavily disturbed and compacted surface soils. As such, native vegetation communities do not occur
within the project site; instead it is comprised of disturbed and developed land dominated by non-native
and ornamental plant species. Residential land uses comprise the northeast and southeast corners of the
project site. In addition, residential land uses comprise the western portion of the project site. Remnant
greenhouse structures can be found in the eastern portion of the project site. Areas surrounding the project
site primarily consist of residential land uses. Refer to Attachment C for representative photographs of the
project site taken during the field survey.
Vegetation Communities and Land Cover Types
As previously stated, the project site consists of disturbed/developed land that is subject to routine weed
abatement, resulting in heavily disturbed and compacted surface soils. As such, native vegetation
communities do not occur within the project site; instead it is comprised of disturbed and developed land
dominated by non-native and ornamental plant species. These land uses are depicted on Figure 1, Vegetation
Communities and Other Land Uses, and described in further detail below. In addition, refer to the
paragraphs below for descriptions of plant species observed within the project site during the field survey.
Ornamental
Approximately 0.20-acre of ornamental vegetation occurs within the central portion of the project site.
China berry tree (Melia azedarach) dominates this area.
Disturbed Habitat
Disturbed habitat comprises approximately 8.87 acres of the project site. Disturbed areas within the project
site do not comprise a natural plant community and instead consist of unpaved bare ground or areas that
have been previously disked or tilled as part of routine weed abatement activities. Surface soils within these
areas have been heavily disturbed/compacted as a result of anthropogenic disturbances and are either devoid
of vegetation or support non-native, ruderal plant species. Plant species observed in the disturbed areas
include crabgrass (Digitaria sanguinalis), telegraph weed (Heterotheca grandiflora), common
Mediterranean grass (Schismus barbatus), coastal heron’s bill (Erodium cicutarium), giant reed (Arundo
donax), flax-leaved horseweed (Erigeron bonariensis), golden crownbeard (Verbesina encelioides),
Russian thistle (Salsola tragus), and annual bursage (Ambrosia acanthicarpa). In addition, sparse
individuals of Fremont cottonwood (Populus fremontii), California sycamore (Platanus racemosa), and
Fontana 47 5
Habitat Assessment
silver dollar gum (Eucalyptus polyanthemos) can be found within the eastern and southern portion of the
project site.
Developed
Developed areas make up approximately 3.52 acres of the project site and consist of existing structures,
land that have been constructed upon, or areas that have been physically altered to a degree that native
vegetation is no longer supported. Developed areas within the project site consist of the remnant greenhouse
structures, residential development within the northeast, southeast, and western portions of the project site,
Orchid Avenue, and Catawba Avenue.
Wildlife
Natural vegetation communities provide foraging habitat, nesting/denning sites, and shelter from adverse
weather or predation. This section provides a general discussion of common wildlife species that were
detected by Michael Baker during the field survey or that are expected to occur based on existing site
conditions. The discussion is to be used as a general reference and is limited by the season, time of day, and
weather conditions in which the field survey was conducted. Refer to the paragraphs below for descriptions
of wildlife species observed within the project site during the field survey.
Fish
No fish or hydrogeomorphic features (e.g., perennial creeks, ponds, lakes, reservoirs) with frequent sources
of water that would support populations of fish were observed in the project site during the field survey.
Therefore, no fish are expected to occur.
Amphibians
No amphibians or hydrogeomorphic features (e.g., perennial creeks, ponds, lakes, reservoirs) that would
provide suitable breeding habitat for amphibians were observed within the project site. Due to routine weed
abatement within the project site and extensive residential development in the project site and surrounding
area, it is highly unlikely that the project site would support a robust population of native amphibian species.
Therefore, no amphibian species are expected to occur.
Reptiles
No reptiles were observed within the project site during the field survey. Since the project site is primarily
disturbed/developed, it is expected to provide suitable habitat for a limited number of reptilian species that
are acclimated to edge or urban environments. Reptilian species that may be present within the project site
include western side-blotched lizard (Uta stansburiana elegans), Great Basin fence lizard (Sceloporus
occidentalis longipes), and San Diego alligator lizard (Elgaria multicarinata webbii).
Birds
The project site provides marginal foraging and nesting habitat for a variety of resident and migrant bird
species that are adapted to a high degree of disturbance associated with the surrounding residential land
uses. Fifteen (15) bird species were detected during the field survey, including northern flicker (Colaptes
auratus), rock dove (Columba livia), American crow (Corvus brachyrhynchos), American kestrel (Falco
sparverius), house finch (Haemorhous mexicanus), northern mockingbird (Mimus polyglottos), house
Fontana 47 6

sparrow (Passer domesticus), black phoebe (Sayornis nigricans), lesser goldfinch (Spinus psaltria),
Eurasian collared dove (Streptopelia decaocto), western meadowlark (Sturnella neglecta), common starling
(Sturnus vulgaris), Cassin’s kingbird (Tyrannus vociferans), mourning dove (Zenaida macroura), and
white-crowned sparrow (Zonotrichia leucophrys).
Nesting birds are protected pursuant to the federal Migratory Bird Treaty Act (MBTA) of 1918 and the
California Fish and Game Code (CFGC)2. To maintain compliance with the MBTA and CFGC, clearance
surveys are typically required prior to any ground disturbance or vegetation removal activities to avoid
direct or indirect impacts to active bird nests and/or nesting birds. Consequently, if an active bird nest is
destroyed or if project activities result in indirect impacts (e.g., nest abandonment, loss of reproductive
effort) to nesting birds, it is considered “take” and is potentially punishable by fines and/or imprisonment.
The project site provides marginal nesting habitat for year-round and seasonal avian residents as well as
migrating songbirds that could occur in the area. Additionally, the project site provides nesting habitat for
avian species that nest on the open ground (e.g., killdeer [Charadrius vociferus], western meadowlark).
One (1) remnant nest was observed approximately 150 feet to the north of the project site within a
eucalyptus tree; however, no remnant nests were observed within the project site. Further, no active nests
or birds displaying nesting behavior were observed.
Mammals
The project site provides suitable habitat for a limited number of mammalian species adapted to living in
edge or urban environments. However, the routine weed abatement and surrounding residential
development limits the potential for mammalian species to occur. Domestic cat (Felis catus) was the only
mammal species observed during the field survey. Other common mammalian species that may occur
within the project site include coyote (Canis latrans), domestic dog (Canis lupus familiaris), opossum
(Didelphis virginiana), raccoon (Procyon lotor), and desert cottontail (Sylvilagus audubonii).
Bats occur throughout most of southern California and may use the project site as foraging habitat; however,
the project site is heavily disturbed and is surrounded by residential development. Common bat species that
may forage within the project site include Mexican free-tailed bat (Tadarida brasiliensis) and big brown
bat (Eptesicus fuscus). Mexican free-tailed bats prefer caves or manmade structures (i.e., bridges,
abandoned buildings) near water for roosting while big brown bat prefers hollow tree snags/limbs, loose
bark, or manmade structures (i.e., bridges, abandoned buildings, barns) for roosting; however, these features
are not present within the project site.
Migratory Corridors and Linkages
Wildlife corridors and linkages are key features for wildlife movement between habitat patches. Wildlife
corridors are generally defined as those areas that provide opportunities for individuals or local populations
to conduct seasonal migrations, permanent dispersals, or daily commutes, while linkages generally refer to
broader areas that provide movement opportunities for multiple keystone/focal species or allow for
2 Section 3503 makes it unlawful to take, possess, or needlessly destroy the nest or eggs of any bird, except as otherwise provided
by the CFGC or any regulation made pursuant thereto; Section 3503.5 makes it unlawful to take, possess, or destroy any birds
in the orders Falconiformes or Strigiformes (birds-of-prey); and Section 3513 makes it unlawful to take or possess any migratory
non-game bird except as provided by the rules and regulations adopted by the Secretary of the Interior under provisions of the
MBTA, as amended (16 U.S.C. § 703 et seq.).

propagation of ecological processes (e.g., for movement of pollinators), often between areas of conserved
land.
The project site is not located within any wildlife corridors, wilderness areas, wilderness study areas, or
areas of critical environmental concern identified in the San Bernardino County Land Use Plan (County of
San Bernardino, 2007). The project site is located within a heavily developed area of the City of Fontana
and is surrounded by residential development and highly trafficked roadways (i.e., Merrill Avenue to the
north, Fontana Avenue to the east, Randall Avenue to the south). The surrounding residential land uses
have fragmented the connection between the project site and surrounding naturally occurring vegetation
communities. The disturbed and developed landscape of the project site and absence of native vegetation
for cover most likely precludes the movement of wildlife through the project site. Further, elevated noise
levels, vehicle traffic, lighting, and human presence associated with the surrounding residential
development and roadways, decrease the suitability of the project site to be used as a wildlife movement
corridor or linkage.
State and Federal Jurisdictional Resources
There are three agencies that regulate activities within inland streams, wetlands, and riparian areas in
California. The U.S. Army Corps of Engineers (Corps) Regulatory Branch regulates discharge of dredged
or fill material into “waters of the U.S.” pursuant to Section 404 of the CWA and Section 10 of the Rivers
and Harbors Act. Of the State agencies, the Regional Water Quality Control Board (Regional Board)
regulates discharges to surface waters pursuant to Section 401 of the CWA and Section 13263 of the
California Porter-Cologne Water Quality Control Act and the CDFW regulates alterations to streambed and
associated vegetation communities under Section 1600 et seq. of the CFGC.
No jurisdictional drainage or wetland features were observed within the boundaries of the project site.
Therefore, development of the project site would not result in impacts to Corps, Regional Board, or CDFW
jurisdictional areas and regulatory approvals would not be required.
Special-Status Biological Resources
The CNDDB and CNPS Online Inventory were queried for reported locations of special-status plant and
wildlife species as well as special-status natural vegetation communities in the USGS Cucamonga Peak,
Devore, Fontana, and Guasti, California 7.5-minute quadrangles. The field survey was conducted to assess
the conditions of the habitat(s) within the boundaries of the project site to determine if the existing
vegetation communities, at the time of the field survey, have the potential to provide suitable habitat(s) for
special-status plant and wildlife species. Additionally, the potentials for special-status species to occur
within the project site were determined based on the reported locations in the CNDDB and CNPS Online
Inventory and the following:
• Present: the species was observed or detected within the project site during the field survey.
• High: Occurrence records (within 20 years) indicate that the species has been known to occur on
or within 1 mile of the project site and the site is within the normal expected range of this species.
Intact, suitable habitat preferred by this species occurs within the project site and/or there is viable
landscape connectivity to a local known extant population(s) or sighting(s).
• Moderate: Occurrence records (within 20 years) indicate that the species has been known to
occur within 1 mile of the project site and the site is within the normal expected range of this
Fontana 47 8
Habitat Assessment
species. There is suitable habitat within the project site but the site is ecologically isolated from
any local known extant populations or sightings.
• Low: Occurrence records (within 20 years) indicate that the species has been known to occur
within 5 miles of the project site, but the site is outside of the normal expected range of the species
and/or there is poor quality or marginal habitat within the project site.
• Not Expected: There are no occurrence records of the species occurring within 5 miles of the
project site, there is no suitable habitat within the project site, and/or the project site is outside of
the normal expected range for the species.
The literature search identified fifty-seven (57) special-status plant species and sixty-two (62) special-status
wildlife species as occurring within the USGS Cucamonga Peak, Devore, Fontana, and Guasti, California
7.5-minute quadrangles. In addition, five (5) special-status vegetation communities were identified.
Special-status plant and wildlife species were evaluated for their potential to occur within the project site
based on habitat requirements, availability and quality of suitable habitat, and known distributions. Special-
status biological resources identified during the literature review as having the potential to occur within the
vicinity of the project site are presented in Table D-1: Potentially Occurring Special-Status Biological
Resources, provided in Attachment D.
Special-Status Plants
Fifty-seven (57) special-status plant species have been recorded in the USGS Cucamonga Peak, Devore,
Fontana, and Guasti, California 7.5-minute quadrangles by the CNDDB and CNPS Online Inventory (refer
to Attachment D). No special-status plant species were observed during the field survey. The project site is
primarily comprised of residential development and disturbed habitat characterized by heavily
disturbed/compacted soils. Additionally, the routine weed abatement within the project site and surrounding
residential land uses have reduced the potential for the project site to provide suitable habitat for special-
status plant species. Based on the results of the habitat assessment and a review specific habitat preferences,
occurrence records, known distributions, and elevation ranges, it was determined that the special-status
plant species identified by the CNDDB and CNPS databases are not expected to occur within the project
site.
Special-Status Wildlife
Sixty-two (62) special-status wildlife species have been recorded in the USGS Cucamonga Peak, Devore,
Fontana, and Guasti, California 7.5-minute quadrangles by the CNDDB (refer to Attachment D). No
special-status wildlife species identified by the CNDDB were observed within the project site during the
field survey. Based on the results of the field survey and a review of specific habitat preferences, occurrence
records, known distributions, and elevation ranges, it was determined that the project site has a low potential
to support Cooper’s hawk (Accipiter cooperii; a CDFW Watch List species), sharp-shinned hawk (Accipiter
striatus; a CDFW Watch List species), and California horned lark (Eremophila alpestris actia; a CDFW
Watch List species). All remaining special-status wildlife species identified by the CNDDB database are
not expected to occur within the project site.
Special-Status Vegetation Communities
Five (5) special-status vegetation communities have been reported in the USGS Cucamonga Peak, Devore,
Fontana, and Guasti, California 7.5-minute quadrangles by the CNDDB: California Walnut Woodland,
Fontana 47 9
Habitat Assessment
Coastal and Valley Freshwater Marsh, Riversidian Alluvial Fan Sage Scrub, Southern Riparian Forest, and
Southern Sycamore Alder Riparian Woodland. The project site is comprised of residential development
and disturbed habitat that is subject to routine weed abatement, resulting in heavily disturbed and compacted
surface soils which reduces the likelihood of a special-status vegetation community from establishing. As
such, no special-status vegetation communities were observed within the project site during the field survey.
Critical Habitat
Under the definition used by the Federal Endangered Species Act (FESA), “Critical Habitat” refers to
specific areas within the geographical range of a species that were occupied at the time it was listed that
contain the physical or biological features that are essential to the survival and eventual recovery of that
species and that may require special management considerations or protection, regardless of whether the
species is still extant in the area. Areas that were not known to be occupied at the time a species was listed
can also be designated as Critical Habitat if they contain one or more of the physical or biological features
that are essential to that species’ conservation and if the occupied areas are inadequate to ensure the species’
recovery. If a project may result in take or adverse modification to a species’ designated Critical Habitat
and the project has a federal nexus, the project proponent may be required to provide suitable mitigation.
Projects with a federal nexus include those that occur on federal lands, require federal permits (e.g., federal
Clean Water Act [CWA] Section 404 permit), or receive any federal oversight or funding. If there is a
federal nexus, then the federal agency that is responsible for providing funds or permits would be required
to consult with the USFWS under the FESA. The project site is not located within any federally-designated
Critical Habitat.
Conclusions and Recommendations
The project site is primarily comprised of residential development and disturbed habitat that is subject to
routine weed abatement, resulting in heavily disturbed and compacted surface soils. As such, native
vegetation communities do not occur within the project site; instead it is comprised of disturbed and
developed land dominated by non-native and ornamental plant species.
No special-status plant species were observed during the field survey. The residential development and
routine weed abatement within the project site and surrounding residential land uses have reduced the
potential for the project site to provide suitable habitat for special-status plant species. Based on the results
of the literature review and the field survey, Michael Baker determined that all remaining special-status
plant species identified by the CNDDB and CNPS databases are not expected to occur within the project
site based on existing site conditions and a review of specific habitat preferences, occurrence records,
known distributions, and elevation ranges.
No special-status wildlife species were observed within the project site during the field survey. Based on
the results of the habitat assessment and a review of specific habitat preferences, occurrence records, known
distributions, and elevation ranges, it was determined that the project site has a low potential to support
Cooper’s hawk, sharp-shinned hawk, and California horned lark. All remaining special-status wildlife
species identified by the CNDDB database are not expected to occur within the project site.
The project site and surrounding vegetation communities provide suitable foraging and nesting habitat for
a variety of year-round and seasonal avian residents as well as migrating songbirds that could occur in the
area. Nesting birds are protected under the MBTA, the Bald and Golden Eagle Protection Act, and the
Fontana 47 10
Habitat Assessment
CFGC. If project-related activities are to be initiated during the nesting season (January 1st to August 31st),
a pre-construction nesting bird clearance survey should be conducted by a qualified biologist no more than
three (3) days prior to the start of any vegetation removal or ground disturbing activities. The survey should
be conducted by a qualified biologist and cover all suitable nesting habitat within the project impact area,
and areas within a biologically defensible buffer zone surrounding the project impact area. Further, if an
active bird nest is found, the qualified biologist should identify the specific bird species and establish a “no-
disturbance” buffer around the active nest to avoid potential direct and indirect impacts. It is further
recommended that the qualified biologist periodically monitor any active bird nests to determine if project-
related activities disturb the birds and if the “no disturbance” buffer should be increased. Once the young
have fledged and left the nest, or the nest otherwise becomes inactive under natural conditions, project
activities within the “no-disturbance” buffer may occur following an additional survey by the qualified
biologist to search for any new nests in the restricted area.
Although no burrowing owls were observed during the field survey, a pre-construction burrowing owl
clearance survey should be conducted by a qualified biologist to ensure that burrowing owls remain absent
from the project site and impacts to burrowing owls do not occur. The pre-construction clearance surveys
should be conducted no more than 30 days prior to any vegetation removal or ground disturbing activities
and in accordance with the Staff Report on Burrowing Owl Mitigation (CDFW, 2012). Documentation of
surveys and findings shall be submitted to the City of Fontana for review and file. If no burrowing owls or
occupied burrows are detected, construction may begin. If an occupied burrow is found within the
development footprint during pre-construction clearance surveys, a burrowing owl exclusion and mitigation
plan would need to be prepared and submitted to CDFW for approval prior to initiating project activities.

S3
Yearlong resident of California. Primarily
a grassland species, but it persists and
even thrives in some landscapes highly
altered by human activity. Occurs in open,
annual or perennial grasslands, deserts,
and scrublands characterized by low-
growing vegetation. The overriding
characteristics of suitable habitat appear to
be burrows for roosting and nesting and
relatively short vegetation with only
sparse shrubs and taller vegetation.
No Not Expected: No
burrowing owls or suitable
burrows (>4 inches in
diameter) capable of
providing roosting and
nesting opportunities were
observed within the project
site. The lack of suitable
burrows, quality of surface
soils within the project site,
ongoing weed abatement,
and the surrounding
residential land uses likely
preclude burrowing owls
from occurring. In addition,
the presence of telephone
and light poles are expected
to further decrease the
likelihood that burrowing
owls would occur within the
project site as these features
provide perching
opportunities for larger
raptors (e.g., red-tailed hawk

Habitat Assessment
* U.S. Fish and Wildlife Service (USFWS)
FE Endangered – any species which is in danger of extinction throughout all or a significant portion of its range.
FT Threatened – any species which is likely to become an endangered species within the foreseeable future throughout all or a
significant portion of its range.
California Department of Fish and Wildlife (CDFW)
SE Endangered – any native species or subspecies of bird, mammal, fish, amphibian, reptile, or plant which is in serious danger
of becoming extinct throughout all, or a significant portion, of its range due to one or more causes, including loss of habitat,
change in habitat, overexploitation, predation, competition, or disease.
SCE State Candidate for Listing as Endangered – the classification provided to a native species or subspecies of a bird, mammal,
fish, amphibian, reptile, or plant that the Fish and Game Commission has formally noticed as being under review by the
Department of Fish and Wildlife for addition to the list of endangered species, or a species for which the commission has
published a notice of proposed regulation to add the species to the list of endangered species.
ST Threatened – any native species or subspecies of bird, mammal, fish, amphibian, reptile, or plant that, although not presently
threatened with extinction, is likely to become an endangered species in the foreseeable future in the absence of the special
protection and management efforts required under the California Endangered Species Act.
FP Fully Protected – any native species or subspecies of bird, mammal, fish, amphibian, or reptile that were determined by the
State of California to be rare or face possible extinction.
SSC Species of Special Concern – any species, subspecies, or distinct population of fish, amphibian, reptile, bird, or mammal
native to California that currently satisfies one or more of the following criteria:
- is extirpated from California or, in the case of birds, in its primary seasonal or breeding role;
- is listed as Federally-, but not State-, threatened or endangered; meets the State definition of threatened or
endangered but has not formally been listed.
- is experiencing, or formerly experienced, serious (noncyclical) population declines or range retractions (not
reversed) that, if continued or resumed, could qualify it for State threatened or endangered status; or
- has naturally small populations exhibiting high susceptibility to risk from any factor(s), that if realized, could
lead to declines that would qualify it for State threatened or endangered status.
WL Watch List - taxa that were previously designated as “Species of Special Concern” but no longer merit that status, or which
do not yet meet SSC criteria, but for which there is concern and a need for additional information to clarify status.
California Native Plant Society (CNPS) California Rare Plant Rank
1A Presumed extirpated in California and either rare or extinct elsewhere.
1B Plants rare, threatened, or endangered in California and elsewhere.
2B Plants rare, threatened, or endangered in California but more common elsewhere.
4 Plants of limited distribution – Watch List.
Threat Ranks
.1 Seriously threatened in California (over 80% of occurrences threatened/high degree any immediacy of threat).
.2 Moderately threatened in California (20 to 80 percent of occurrences threatened/moderate degree and
immediacy of threat).
.3 Not very threatened in California (less than 20 percent of occurrences threatened/low degree and immediacy
of threat or no current threats known).
NatureServe Conservation Status Rank
The Global Rank (G#) reflects the overall condition and imperilment of a species throughout its global range. The Infraspecific Taxon Rank
(T#) reflects the global situation of just the subspecies or variety. The State Rank (S#) reflects the condition and imperilment of an element
throughout its range within California. (G#Q) reflects that the element is very rare but there are taxonomic questions associated with it; the
calculated G rank is qualified by adding a Q after the G#). Adding a ? to a rank expresses uncertainty about the rank.
G1/T1 Critically Imperiled – At very high risk of extinction due to extreme rarity (often 5 or fewer populations), very steep declines,
or other factors.
G2/T2 Imperiled— At high risk of extinction due to very restricted range, very few populations (often 20 or fewer), steep declines,
or other factors.
G3/T3 Vulnerable— At moderate risk of extinction due to a restricted range, relatively few populations (often 80 or fewer), recent
and widespread declines, or other factors.
G4/T4 Apparently Secure— Uncommon but not rare; some cause for long-term concern due to declines or other factors.
G5 Secure – Common; widespread and abundant.
S1 Critically Imperiled – Critically imperiled in the state because of extreme rarity (often 5 or fewer occurrences) or because of
some factor(s) such as very steep declines making it especially vulnerable to extirpation from the State.
S2 Imperiled – Imperiled in the State because of rarity due to very restricted range, very few populations (often 20 or fewer),
steep declines, or other factors making it very vulnerable to extirpation from the nation or State.
S3 Vulnerable – Vulnerable in the State due to a restricted range, relatively few populations (often 80 or fewer), recent and
widespread declines, or other factors making it vulnerable to extirpation.
S4 Apparently Secure – Uncommon but not rare; some cause for long-term concern due to declines or other factors.
