SUBJECT: Biological Resources Assessment for the Proposed Project Located within Assessor
Parcel Number 1108-081-04 in the City of Fontana, San Bernardino County,
California
Introduction
This report contains the findings of ELMT Consulting’s (ELMT) biological resources assessment for the
proposed multi-tenant project (project site or site) located within Assessor Parcel Number (APN) 1108-
081-04 in the City of Fontana, San Bernardino County, California. The initial habitat assessment was
conducted on October 25, 2023, and a follow up survey was conducted on October 29, 2025 to document
baseline conditions and assess the potential for special-status1 plant and wildlife species to occur within the
project site that could pose a constraint to implementation of the proposed project. Special attention was
given to the suitability of the project site to support burrowing owl (Athene cunicularia), San Bernardino
kangaroo rat (Dipodomys merriami parvus), California gnatcatcher (Polioptila californica californica), and
other special-status plant and wildlife species identified by the California Department of Fish and Wildlife’s
(CDFW) California Natural Diversity Database (CNDDB), and other electronic databases as potentially
occurring in the general vicinity of the project.
Additionally, the report also addresses resources protected under the Migratory Bird Treaty Act (MBTA)
and California Fish and Game Code (FGC), federal Clean Water Act (CWA) regulated by the United States
Army Corps of Engineers (Corps) and Regional Water Quality Control Board (Regional Board)
respectively, and Section 1602 of the FGC administered by CDFW.
Project Location
The project site is generally located north of State Route 210, southeast of Interstate 15, and southwest of
Interstate 215 in the City of Fontana, San Bernardino County, California. The site is depicted on the Devore
quadrangle of the United States Geological Survey’s (USGS) 7.5-minute map series within section 25 of
Township 1 North, Range 6 West. Specifically, the project site is bounded to the south by Curtis Avenue
and is located within APN 1108-081-04. Refer to Exhibits 1-3 in Attachment A.
1 As used in this report, “special-status” refers to plant and wildlife species that are federally and State listed, proposed, or
candidates; plant species that have been designated with a California Native Plant Society Rare Plant Rank; wildlife species that
are designated by the CDFW as fully protected, species of special concern, or watch list species; and specially protected natural
vegetation communities as designated by the CDFW.

Biological Resources Assessment
Methodology
A literature review and records search were conducted to determine which special-status biological
resources have the potential to occur on or within the general vicinity of the project site. In addition to the
literature review, a general habitat assessment or field investigation of the project site was conducted to
document existing conditions and assess the potential for special-status biological resources to occur within
the project site.
Literature Review
Prior to conducting the field investigation, a literature review and records search was conducted for special-
status biological resources potentially occurring on or within the vicinity of the project site. Previously
recorded occurrences of special-status plant and wildlife species and their proximity to the project site was
determined through a query of the CDFW’s QuickView Tool in the Biogeographic Information and
Observation System (BIOS), CNDDB Rarefind 5, the California Native Plant Society’s (CNPS) Electronic
Inventory of Rare and Endangered Vascular Plants of California, Calflora Database, compendia of special-
status species published by CDFW, and the United States Fish and Wildlife Service (USFWS) species
listings.
All available reports, survey results, and literature detailing the biological resources previously observed
on or within the vicinity of the project site was reviewed to understand existing site conditions 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 and non-special-status biological resources, as well as the following
resources:
• Google Earth Pro historic aerial imagery (1985-2025);
• United States Department of Agriculture (USDA) Natural Resource Conservation Service (NRCS),
Soil Survey 2;
• USFWS Critical Habitat designations for Threatened and Endangered Species; and
• USFWS Endangered Species Profiles.
The literature review provided a baseline from which to inventory the biological resources potentially
occurring within the project site. The CNDDB database was used, in conjunction with ArcGIS software, to
locate the nearest recorded occurrences of special-status species and determine the distance from the project
site.
Field Investigation
Following the literature review, ELMT biologists inventoried and evaluated the condition of the habitat
within the project site on October 25, 2023. A follow up survey was conducted on October 29, 2025 to
reconfirm existing site conditions. Plant communities and land cover types identified on aerial photographs
during the literature review were verified by walking meandering transects throughout the project site. In
2 A soil series is defined as a group of soils with similar profiles developed from similar parent materials under comparable climatic
and vegetation conditions. These profiles include major horizons with similar thickness, arrangement, and other important
characteristics, which may promote favorable conditions for certain biological resources.

Biological Resources Assessment
addition, aerial photography was reviewed prior to the site investigation to locate potential natural corridors
and linkages that may support the movement of wildlife through the area. These areas identified on aerial
photography were then walked during the field investigation.
Soil Series Assessment
On-site and adjoining soils were researched prior to the field investigation using the USDA NRCS Soil
Survey for San Bernardino County, California. In addition, a review of the local geological conditions and
historical aerial photographs was conducted to assess the ecological changes that the project site has
undergone.
Plant Communities
Plant communities were mapped using 7.5-minute USGS topographic base maps and aerial photography.
The plant communities were classified in accordance with Sawyer, Keeler-Wolf and Evens (2009),
delineated on an aerial photograph, and then digitized into GIS Arcview. The Arcview application was used
to compute the area of each plant community and/or land cover type in acres.
Plants
Common plant species observed during the field investigation were identified by visual characteristics and
morphology in the field and recorded in a field notebook. Unusual and less-familiar plants were
photographed in the field and identified in the laboratory using taxonomic guides. Taxonomic nomenclature
used in this study follows the 2012 Jepson Manual (Hickman 2012). In this report, scientific names are
provided immediately following common names of plant species (first reference only).
Wildlife
Wildlife species detected during the field investigation by sight, calls, tracks, scat, or other sign were
recorded during surveys in a field notebook. Field guides used to assist with identification of wildlife
species during the survey included The Sibley Field Guide to the Birds of Western North America (Sibley
2003), A Field Guide to Western Reptiles and Amphibians (Stebbins 2003), 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 in this report (first reference only).
Jurisdictional Drainages and Wetlands
Aerial photography was reviewed prior to conducting a field investigation in order to locate and inspect
any potential natural drainage features, ponded areas, or water bodies that may fall under the jurisdiction
of the United States Army Corps of Engineers (Corps), Regional Water Quality Control Board (Regional
Board), or CDFW. In general, surface drainage features indicated as blue-line streams on USGS maps that
are observed or expected to exhibit evidence of flow are considered potential riparian/riverine habitat and
are also subject to state and federal regulatory jurisdiction. In addition, ELMT reviewed jurisdictional
waters information through examining historical aerial photographs to gain an understanding of the impact
of land-use on natural drainage patterns in the area. The USFWS National Wetland Inventory (NWI) and
Environmental Protection Agency (EPA) Water Program “My Waters” data layers were also reviewed to
determine whether any hydrologic features and wetland areas have been documented on or within the
vicinity of the project site.

Biological Resources Assessment
Existing Site Conditions
The proposed project site is located in an area that historically supported agricultural land uses and rural
communities and has undergone significant urbanization in recent decades. At present, the site is bounded
to the west, north, and east by residential development, and to the south by Curtis Avenue with residential
and recreational developments beyond. The site itself supports developed land and undeveloped, vacant
land that has been impacted by several decades of vehicle access, staging and stockpiling activities
associated with surrounding construction, weed abatement activities, illegal dumping, and various other
impacts associated with on-site and surrounding development. According to historic aerials, these
disturbances have been ongoing since at least 1938, with the site being entirely surrounded by development
or construction since 2018.
Topography and Soils
On-site elevation ranges from approximately 1,560 to 1,585 feet above mean sea level and generally slopes
from north to south. On-site topography is generally flat with no areas of significant topographic relief.
Based on the NRCS USDA Web Soil Survey, the project site is historically underlain by Soboba gravelly
loamy sand (0 to 9 percent slopes). Refer to Exhibit 4, Soils, in Attachment A. Soils on-site are generally
very rocky and have been mechanically disturbed and compacted from grading activities, historic and
ongoing land uses, and surrounding development.
Vegetation
The project site supports one (1) plant community: degraded chamise chaparral. In addition, the site
supports two (2) land cover types that would be classified as disturbed and developed (refer to Exhibit 5,
Vegetation, in Attachment A). Refer to Attachment B, Site Photographs, for representative site
photographs.
The project site supports a degraded chamise chaparral plant community following decades of disturbance
and isolation from local fluvial processes. The degraded chamise chaparral plant commuinty found onsite
has been isolated from the fluvial influences of Lytle Creek for several decades since the installation of
levees and other flood control infrastructure to the north.
The absence of seasonal scouring has resulted in a generally uniform, albeit sparse, distribution of woody
native perennial species, with an herbaceous layer dominated by non-native annual plant species. Common
native plant species observed in this plant community include deer weed (Acmispon glaber), chamise
(Adenostoma fasciculatum), California croton (Croton californicus), doveweed (Croton setiger), sacred
datura (Datura wrightii), Canada horseweed (Erigeron canadensis), California buckwheat (Eriogonum
fasciculatum), common sunflower (Helianthus annuus), telegraph weed (Heterotheca grandiflora), wild
cucumber (Marah macrocarpa), hollyleaf cherry (Prunus ilicifolia), fragrant sumac (Rhus aromatica), and
twiggy wreath plant (Stephanomeria virgata); and common non-native species observed include wild oat
(Avena sp.), nettleleaf goosefoot (Chenopodium murale), longbeak stork's bill (Erodium botrys), redstem
stork's bill (Erodium cicutarum), spotted spurge (Euphorbia maculata), shortpod mustard (Hirschfeldia
incana), cheeseweed mallow (Malva parviflora), tree tobacco (Nicotiana glauca), russian thistle (Salsola
tragus), Mediterranean grass (Schismus barbatus), common sowthistle (Sonchus oleraceus), and puncture
vine (Tribulus terrestris).

Biological Resources Assessment
Disturbed land is supported along site boundaries, within areas adjacent to developed land, and within
artificial strips that are maintained during weed-abatement activities. These areas vary from minimally to
densely vegetated and are dominated by the same non-native weedy/early successional species observed in
the degraded chamise chaparral plant community.
Developed areas generally encompass all buildings/structures, parks, and paved or otherwise impervious
surfaces. Within the boundaries of the project site, developed areas include an existing temporary office
building and parking area in the southwest corner, and along the western and eastern boundaries, where
compacted gravel access roads were installed to accommodate materials and equipment transport during
construction of adjacent residential developments. These areas are often barren to moderately vegetated
with especially weedy non-native species.
Wildlife
Plant communities provide foraging habitat, nesting/denning sites, and shelter from adverse weather or
predation. This section provides a discussion of those wildlife species that were observed or are expected
to occur within the project site. The discussion is to be used a general reference and is limited by the season,
time of day, and weather conditions in which the field investigation was conducted. Wildlife detections
were based on calls, songs, scat, tracks, burrows, and direct observation. The project site provides limited
habitat for wildlife species except those adapted to a high degree of anthropogenic disturbances and
development.
Fish
No fish or hydrogeomorphic features (e.g., creeks, ponds, lakes, reservoirs) with frequent sources of water
that would support populations of fish were observed on or within the vicinity of the project site. Therefore,
no fish are expected to occur and are presumed absent from the project site.
Amphibians
No amphibians or hydrogeomorphic features (e.g., perennial creeks, ponds, lakes, reservoirs) that would
provide suitable habitat for amphibian species were observed on or within the vicinity of the project site.
Therefore, no amphibians are expected to occur and are presumed absent from the project site.
Reptiles
The project site provides suitable foraging and cover habitat for a limited variety of local reptile species
adapted to routine anthropogenic disturbance and general isolation by nearby development. The only
reptilian species observed during the field investigation was western side-blotched lizard (Uta stansburiana
elegans). Other common reptilian species that could be expected to occur on-site include great basin fence
lizard (Sceloporus occidentalis longipes) and San Diego alligator lizard (Elgaria multicarinata webbii).
Birds
The project site and surrounding area provide suitable foraging and nesting habitat for a variety of local
bird species. Bird species detected during the field investigation include rock pigeon (Columba livia),
california scrub-jay (Aphelocoma californica), anna's hummingbird (Calypte anna), common raven
(Corvus corax), american kestrel (Falco sparverius), house finch (Haemorhous mexicanus), california

towhee (Melozone crissalis), northern mockingbird (Mimus polyglottos), savannah sparrow (Passerculus
sandwichensis), black phoebe (Sayornis nigricans), yellow-rumped warbler (Setophaga coronata), western
meadowlark (Sturnella neglecta), lesser goldfinch (Spinus psaltria), white-crowned sparrow (Zonotrichia
leucophrys), song sparrow (Melospiza melodia), and mourning dove (Zenaida macroura).
Mammals
The project site provides suitable foraging and cover habitat for a mammalian species adapted to routine
anthropogenic disturbance and general isolation from nearby development. Mammalian species detected
during the field investigation include coyote (Canis latrans), kangaroo rat (Dipodomys sp.), domestic cat
(Felis catus), and pocket gopher (Thomomys bottae). It should be noted that domestic cats supported on-
site are provided food by local residents, as evidenced by pet food bowls observed in this area. Additional
common mammalian species that could be expected to occur on-site include opossum (Didelphis
virginiana), deer mouse (Peromyscus californicus), and raccoon (Procyon lotor).
Nesting Birds
No active avian nests or birds exhibiting nesting behavior were observed during the field investigation,
which was conducted outside of breeding season. The project site and surrounding area provide suitable
foraging habitat and nesting opportunities for a variety of year-round and seasonal avian residents, as well
as migrating songbirds that could occur in the area. In addition, the project site has the potential to provide
suitable nesting opportunities for birds that nest on the open ground. Raptors are not expected to nest on-
site due to the lack of suitable nesting opportunities.
Nesting birds are protected pursuant to the Migratory Bird Treaty Act (MBTA) and California Fish and
Game Code (Sections 3503, 3503.5, 3511, and 3513 prohibit the take, possession, or destruction of birds,
their nests or eggs). If construction occurs between February 1st and August 31st, a pre-construction
clearance survey for nesting birds should be conducted within three (3) days of the start of any vegetation
removal or ground disturbing activities to ensure that no nesting birds will be disturbed during construction.
Migratory Corridors and Linkages
Habitat linkages provide connections between larger habitat areas that are separated by development.
Wildlife corridors are similar to linkages but provide specific opportunities for animals to disperse or
migrate between areas. A corridor can be defined as a linear landscape feature of sufficient width to allow
animal movement between two comparatively undisturbed habitat fragments. Adequate cover is essential
for a corridor to function as a wildlife movement area. It is possible for a habitat corridor to be adequate for
one species yet still inadequate for others. Wildlife corridors are features that allow for the dispersal,
seasonal migration, breeding, and foraging of a variety of wildlife species. Additionally, open space can
provide a buffer against both human disturbance and natural fluctuations in resources.
According to the San Bernardino County General Plan, the project site is not mapped as occurring within
or adjacent to any Major Open Space Areas. The nearest Major Open Space Area to the project site is Cajon
Pass; in proximity to the site, the Cajon Pass is composed of the Lytle Creek and Cajon Creek washes.
However, in the years since the Major Open Space Areas were mapped, the southwest portion of the Cajon
Pass has been largely developed and presently supports mostly residential tract neighborhoods. At present,
remaining open space in proximity to the project site occurs approximately 1.5 miles to the northeast beyond

Biological Resources Assessment
existing development. Additionally, there are no riparian corridors, creeks, or useful patches of
steppingstone habitat (natural areas) within or connecting the project site to these, or any other, identified
wildlife corridors or linkages. As a result, implementation of the proposed project will not disrupt or have
any adverse effects on any migratory corridors or linkages in the surrounding area.
Jurisdictional Areas
There are three key agencies that regulate activities within inland streams, wetlands, and riparian areas in
California. The Corps Regulatory Branch regulates discharge of dredge or fill materials into “waters of the
United States” pursuant to Section 404 of the Clean Water Act (CWA) and Section 10 of the Rivers and
Harbors Act. Of the State agencies, the CDFW regulates alterations to streambed and bank under Fish and
Wildlife Code Sections 1600 et seq., and the Regional Board regulates discharges into surface waters
pursuant to Section 401 of the CWA and the California Porter-Cologne Water Quality Control Act.
No jurisdictional drainage and/or wetland features were observed on the project site during the field
investigation. Further no blueline streams, have been recorded on the project site. Therefore, development
of the project will not result in impacts to Corps, Regional Board, or CDFW jurisdiction and regulatory
approvals will not be required.
Special-Status Biological Resources
The CNDDB Rarefind 5 and the CNPS Electronic Inventory of Rare and Endangered Vascular Plants of
California were queried for reported locations of special-status plant and wildlife species as well as special-
status natural plant communities in the Devore USGS 7.5-minute quadrangle. Only one quadrangle was
queried due to the proximity of the project site to quadrangle boundaries, regional topography, and
surrounding development. The habitat assessment evaluated the conditions of the habitat(s) within the
boundaries of the project site to determine if the existing plant communities, at the time of the survey, have
the potential to provide suitable habitat(s) for special-status plant and wildlife species.
The literature search identified twenty (20) special-status plant species, forty-five (45) special-status
wildlife species, and three (3) special-status plant communities as having the potential to occur within the
Devore 7.5-minute quadrangle. 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. Species determined to have the potential to occur within the general vicinity of
the project site is presented in Attachment D: Potentially Occurring Special-Status Biological Resources.
Special-Status Plants
According to the CNDDB and CNPS, twenty (20) special-status plant species have been recorded in the
Devore quadrangle (refer to Attachment D). No special-status plant species were observed on-site during
the field investigation. The project site has been subject to anthropogenic disturbances from construction
activities, spoils dumping, and adjacent and surrounding development; the latter of which has removed on-
site habitats from historic hydrological regimes that once shaped the vegetative structure of plant
communities in the area. These disturbances have reduced, if not eliminated, the suitability of the habitat to
support special-status plant species known to occur in the general vicinity of the project site.
Based on habitat requirements for specific special-status plant species, the availability and quality of
November 10, 2025
Page 8

Biological Resources Assessment
habitats needed by each species, and known distributions, it was determined that the project site does not
have potential to support any of the special-status plant species known to occur in the vicinity and all are
presumed to be absent. No further surveys are recommended.
Special-Status Wildlife
According to the CNDDB, forty-five (45) special-status wildlife species have been reported in the Devore
quadrangle (refer to Attachment D). No special-status wildlife species were observed during the field
investigation. Based on habitat requirements for specific species and the availability and quality of on-site
habitats, it was determined that the proposed project has a high potential to support Cooper’s hawk
(Accipiter cooperii), Costa’s hummingbird (Calypte costae), and California horned lark (Eremophila
alpestris actia); and a low potential to support Bell's sage sparrow (Artemisiospiza belli belli). It was further
determined that the project site does not have the potential to support any of the remaining special-status
wildlife species known to occur in the vicinity and all are presumed to be absent. None of the
aforementioned species are federally or state listed as endangered or threatened.
Of the aforementioned avian species, only Costa’s hummingbird and Bell’s sage sparrow might be expected
to nest on-site. Cooper’s hawk is not expected to nest on-site due to the lack of suitable nesting opportunities
and California horned lark is not expected to nest on-site as the presence of free-roaming domestic cats
precludes ground-nesting avian species from nesting.
Based on regional significance, the potential occurrence of burrowing owl, San Bernardino kangaroo rat,
and California gnatcatcher within the project site are described in further detail below:
Burrowing Owl
The burrowing owl is currently listed as a California Candidate Endangered Species. It is a grassland
specialist distributed throughout western North America where it occupies open areas with short vegetation
and bare ground within shrub, desert, and grassland environments. Burrowing owls use a wide variety of
arid and semi-arid environments with well-drained, level to gently-sloping areas characterized by sparse
vegetation and bare ground (Haug and Didiuk 1993; Dechant et al. 1999). Burrowing owls are dependent
upon the presence of burrowing mammals (such as ground squirrels) whose burrows are used for roosting
and nesting (Haug and Didiuk 1993). The presence or absence of colonial mammal burrows is often a major
factor that limits the presence or absence of burrowing owls. Where mammal burrows are scarce, burrowing
owls have been found occupying man-made cavities, such as buried and non-functioning drain pipes, stand-
pipes, and dry culverts. Burrowing mammals may burrow beneath rocks and debris or large, heavy objects
such as abandoned cars, concrete blocks, or concrete pads. They also require open vegetation allowing line-
of-sight observation of the surrounding habitat to forage as well as watch for predators.
No burrowing owls or recent sign (i.e., pellets, feathers, castings, or whitewash) were observed during the
field investigation. Portions of the project site are unvegetated and/or vegetated with low-growing plant
species that allow for line-of-sight observation favored by burrowing owls. However, the project site lacks
suitable burrows (>4 inches in diameter) capable of providing nesting opportunities. In addition, the site is
surrounded by electrical and light poles which provide perching opportunities for larger raptor species (i.e.,
red-tailed hawk [Buteo jamaicensis]) that prey on burrowing owls. Burrowing owl is further precluded from
establishing on-site due to the presence of free-roaming domestic cats.
November 10, 2025

APN 1108-081-04
Biological Resources Assessment
Based on the results of the field investigation, it was determined that the project site does not have potential
to support burrowing owl and focused surveys are not recommended. However, out of an abundance of
caution, a preconstruction burrowing owl clearance survey shall be conducted prior to development to
ensure burrowing owl remain absent from the project site.
San Bernardino Kangaroo Rat
The San Bernardino kangaroo rat, federally listed as endangered, is one of several kangaroo rat species in
its range. The Dulzura, the Pacific kangaroo rat (Dipodomys agilis) and the Stephens kangaroo rat
(Dipodomys stephensi) occur in areas occupied by the San Bernardino kangaroo rat, but these other species
have a wider habitat range. The habitat of the San Bernardino kangaroo rat is described as being confined
to pioneer and intermediate Riversidean Alluvial Fan Sage Scrub (RAFSS) habitats, with sandy soils
deposited by fluvial (water) rather than Aeolian (wind) processes. Burrows are dug in loose soil, usually
near or beneath shrubs.
The San Bernardino kangaroo rat is one of three subspecies of the Merriam’s kangaroo rat. The Merriam’s
kangaroo rat is a widespread species that can be found from the inland valleys to the deserts. The subspecies
known as the San Bernardino kangaroo, however, is confined to inland valley scrub communities, and more
particularly, to scrub communities occurring along rivers, streams and drainages. Most of the drainages
have been historically altered as a result of flood control efforts and the resulting increased use of river
resources, including mining, off-road vehicle use and road and housing development. This increased use of
river resources has resulted in a reduction in both the amount and quality of habitat available for the San
Bernardino kangaroo rat. The past habitat losses and potential future losses prompted the emergency listing
of the San Bernardino kangaroo rat as an endangered species (USFWS, 1998a). PCE’s are physical or
biological features essential to the conservation of a species for which its designated critical habitat is based
on. Examples of PCE’s include food, water, space for individual and population growth, cover or shelter,
etc. The PCEs essential to support the biological needs of foraging, reproducing, rearing of young, intra-
specific communication, dispersal, genetic exchange, or sheltering for San Bernardino kangaroo rat are:
1. River, creek, stream, and wash channels; alluvial fans, flood plains, flood benches and terraces; and
historic braided channels that are subject to dynamic geomorphological and hydrological processes;
2. Alluvial sage scrub and associated vegetation such as coastal sage scrub and chamise chaparral
with a moderately open canopy;
3. Soil series consisting of sand, sandy loam, or loam within its geographical range; and
4. Upland areas proximal to flood plains containing suitable habitat (land adjacent to alluvial fan that
provides refugia).
San Bernardino kangaroo rat is known to occur within Lytle Creek. The project site has been generally
removed from the hydrological influences of Lytle Creek since the installation of Interstate 15 and
associated flood control infrastructure since the mid-1900’s, resulting in the on-site RAFSS plant
community no longer exhibiting the dynamic vegetative succession and diversity typical of this plant
community. In addition, the development of extensive residential neighborhood tracts in the mid-1990’s
thoroughly isolated the project site from suitable habitats within downstream portions of Lytle Creek.
Undeveloped portions of the project site are underlain with rocky soils that have been heavily disturbed and
November 10, 2025

compacted following decades of anthropogenic disturbance. Field sign for kangaroo rat, including San
Bernardino kangaroo rat, is distinctive and readily noted in the field. No sign (e.g., San Bernardino kangaroo
rat characteristic burrows, dusting baths, and/or tail drags) was observed during the field investigation.
Additionally, the project site no longer is subject to the hydrologic influence of Lytle Creek due to the
channelization of Lytle Creek flood control purposes.
The project site is not subject to dynamic geomorphological and hydrological processes needed to scour
and reset the onsite habitats back to pioneer or intermediate RAFSS habitats. Further, the project site no
longer receives sand or sandy loam soils from scouring events needed by San Bernardino kangaroo rat for
burrowing. Instead, the site supports compact and rocky soils.
Based on these conditions, it was determined that the project site does not provide the requisite habitat
elements needed by San Bernardino kangaroo rat to be present. Therefore, it was determined that San
Bernardino kangaroo rat is presumed absent from the project site. No focused surveys are recommended.
California Gnatcatcher
California gnatcatcher is a federally threatened species with restricted habitat requirements, being an
obligate resident of sage scrub habitats that are dominated by California sagebrush. This species generally
occurs below 750 feet elevation in coastal regions and below 1,500 feet inland. According to J. Atwood
and J. Bolsinger (1992), 99% of all California gnatcatcher observations are in areas with elevations below
950 feet. There are reported occurrences of California gnatcatcher at 1,600 feet elevation (500 meters).
California gnatcatcher ranges from Ventura County south to San Diego County and northern Baja
California and is less common in sage scrub with a high percentage of tall shrubs. It prefers habitat with
more low-growing vegetation. California gnatcatchers breed between mid-February and the end of August,
with peak activity from mid-March to mid-May. Population estimates indicate that there are approximately
1,600 to 2,290 pairs of coastal California gnatcatcher remaining. Declines are attributed to loss of sage
scrub habitat due to development, as well as cowbird nest parasitism.
California gnatcatcher are ground and shrub-foraging insectivores, feeding on small insects and other
arthropods. A California gnatcatcher’s territory is highly variable in size and seems to be correlated with
distance from the coast, ranging from less than 1 ha to over 9 ha. In a 1998 study, biologist Patrick Mock
concluded that California gnatcatcher in the inland region require a larger territory than those on the coast
in order to meet the nutritional requirements needed for survival and breeding.
The Primary Constituent Elements (PCEs)3 essential to support the biological needs of foraging,
reproducing, rearing of young, intra-specific communication, dispersal, genetic exchange, or sheltering for
California gnatcatcher that were surveyed for include:
1. Dynamic and Successional sage scrub Habitats and Associated Vegetation (Diegan Coastal Sage
Scrub, Coastal Sage-Chaparral Scrub, etc.) that provide space for individual and population growth,
normal behavior, breeding, reproduction, nesting, dispersal and foraging; and
2. Non-sage scrub habitats such as chaparral, grassland, and riparian areas, in proximity to sage scrub
3 Specific elements of physical and biological features that provide for a species’ life-history process and are essential to the
conservation of the species.

habitats have the potential to provide linkages to help with dispersal, foraging and nesting.
The project site ranges in approximate elevation from 1,560 to 1,585 feet above mean sea level, which is
just below the known elevational range of California gnatcatcher. Ninety-nine percent of all California
gnatcatcher observations occur below 950 feet above msl. California gnatcatcher’s preferred habitat is
coastal sage scrub dominated by California sage brush. The project site does not support coastal sage scrub
habitat, which is the preferred habitat for California gnatcatcher In addition, the site is isolated from
California gnatcatcher occupied coastal sage scrub habitats and linkage areas in the region by surrounding
development. Given the degraded condition of the site, plus the lack of any observation of California
gnatcatcher in north Fontana and isolation of the site due to the recent development of surrounding
properties, it is highly unlikely that the site might support this species. Therefore, California gnatcatcher is
presumed to be absent from the project site. No further surveys are recommended.
Special-Status Plant Communities
According to the CNDDB, three (3) special-status plant communities have been reported in the Devore
USGS 7.5-minute quadrangle: RAFSS, Southern Riparian Forest, and Southern Sycamore Alder Riparian
Woodland (refer to Attachment D). No special-status plant communities were observed onsite.
Critical Habitats
Under the federal Endangered Species Act, “Critical Habitat” is designated at the time of listing of a species
or within one year of listing. Critical Habitat refers to specific areas within the geographical range of a
species at the time it is listed that include the physical or biological features that are essential to the survival
and eventual recovery of that species. Maintenance of these physical and biological features requires special
management considerations or protection, regardless of whether individuals or the species are present or
not. All federal agencies are required to consult with the USFWS regarding activities they authorize, fund,
or permit which may affect a federally listed species or its designated Critical Habitat. The purpose of the
consultation is to ensure that projects will not jeopardize the continued existence of the listed species or
adversely modify or destroy its designated Critical Habitat. The designation of Critical Habitat does not
affect private landowners, unless a project they are proposing is on federal lands, uses federal funds, or
requires federal authorization or permits (e.g., funding from the Federal Highways Administration or a
Clean Water Act Permit from the United States Army Corps of Engineers). If there is a federal nexus, then
the federal agency that is responsible for providing the funding or permit would consult with the USFWS.
In 2002 the USFWS designated Critical Habitat for San Bernardino kangaroo rat, and the project site was
included within the designated area. Subsequently, in 2008 the USFWS reduced the boundaries of their
previously designated Critical Habitat which removed the project site from designation. The lack of the
needed habitat features within the project site, as well as in north Fontana, prompted USFWS to remove
the Critical Habitat designation in this area. Finally, at the beginning of 2011 the original (2002) designated
Critical Habitat was reinstated by a federal district court ruling which overturned the reduced (2008)
designated Critical Habitat.
Currently the project site is located within designated Critical Habitat Unit 2, Lytle Creek/Cajon Wash.
Refer to Exhibit 6, Critical Habitat in Attachment A. However, since the project does not have a federal
nexus, a Section 7 consultation with the USFWS would not be required for loss or adverse modification of

Critical Habitat. If a federal nexus does occur, a Section 7 Consultation will have to be initiated with
USFWS.
Conclusion
Based literature review and field survey, and existing site conditions discussed in this report,
implementation of the project is not expected to have significant impacts on federally or State listed species
known to occur in the general vicinity of the project site. Additionally, the project will have no effect on
designated Critical Habitat, since there is no federal nexus, or regional wildlife corridors/linkages because
none exist within the area. No jurisdictional drainage and/or wetland features were observed on the project
site during the field investigation. No further surveys are recommended. With completion of the
recommendations provided below, no impacts to year-round, seasonal, or special-status avian residents or
special-status species will occur from implementation of the proposed project.
Recommendations
Migratory Bird Treaty Act and Fish and Game Code
In order to ensure impacts to special-status avian species (i.e., Bell’s sage sparrow, California horned lark,
Cooper’s hawk, Costa’s hummingbird, and loggerhead shrike) do not occur from implementation of the
proposed project, a pre-construction nesting bird clearance survey shall be conducted prior to ground
disturbance. With implementation of the pre-construction nesting bird clearance survey, impacts to special-
status avian species will be less than significant and no mitigation will be required.
Nesting birds are protected pursuant to the Migratory Bird Treaty Act (MBTA) and California Fish and
Game Code (Sections 3503, 3503.5, 3511, and 3513 prohibit the take, possession, or destruction of birds,
their nests or eggs). In order to protect migratory bird species, a nesting bird clearance survey should be
conducted prior to any ground disturbance or vegetation removal activities that may disrupt the birds during
the nesting season.
If construction occurs between February 1st and August 31st, a pre-construction clearance survey for nesting
birds should be conducted within three (3) days of the start of any vegetation removal or ground disturbing
activities to ensure that no nesting birds will be disturbed during construction. The biologist conducting the
clearance survey should document a negative survey with a brief letter report indicating that no impacts to
active avian nests will occur. If an active avian nest is discovered during the pre-construction clearance
survey, construction activities should stay outside of a no-disturbance buffer. The size of the no-disturbance
buffer will be determined by the wildlife biologist and will depend on the level of noise and/or surrounding
anthropogenic disturbances, line of sight between the nest and the construction activity, type and duration
of construction activity, ambient noise, species habituation, and topographical barriers. These factors will
be evaluated on a case-by-case basis when developing buffer distances. Limits of construction to avoid an
active nest will be established in the field with flagging, fencing, or other appropriate barriers; and
construction personnel will be instructed on the sensitivity of nest areas. A biological monitor should be
present to delineate the boundaries of the buffer area and to monitor the active nest to ensure that nesting
behavior is not adversely affected by the construction activity. Once the young have fledged and left the
nest, or the nest otherwise becomes inactive under natural conditions, construction activities within the
buffer area can occur.

Appendix E – Regulations
Special status species are native species that have been afforded special legal or management protection
because of concern for their continued existence. There are several categories of protection at both federal
and state levels, depending on the magnitude of threat to continued existence and existing knowledge of
population levels.
Federal Regulations
Endangered Species Act of 1973
Federally listed threatened and endangered species and their habitats are protected under provisions of the
Federal Endangered Species Act (ESA). Section 9 of the ESA prohibits “take” of threatened or endangered
species. “Take” under the ESA is defined as to “harass, harm, pursue, hunt, shoot, wound, kill, trap, capture,
or collect, or to attempt to engage in any of the specifically enumerated conduct.” The presence of any
federally threatened or endangered species that are in a project area generally imposes severe constraints
on development, particularly if development would result in “take” of the species or its habitat. Under the
regulations of the ESA, the United States Fish and Wildlife Service (USFWS) may authorize “take” when
it is incidental to, but not the purpose of, an otherwise lawful act.
Critical Habitat is designated for the survival and recovery of species listed as threatened or endangered
under the ESA. Critical Habitat includes those areas occupied by the species, in which are found physical
and biological features that are essential to the conservation of an ESA listed species and which may require
special management considerations or protection. Critical Habitat may also include unoccupied habitat if it
is determined that the unoccupied habitat is essential for the conservation of the species.
Whenever federal agencies authorize, fund, or carry out actions that may adversely modify or destroy
Critical Habitat, they must consult with USFWS under Section 7 of the ESA. The designation of Critical
Habitat does not affect private landowners, unless a project they are proposing uses federal funds, or
requires federal authorization or permits (e.g., funding from the Federal Highway Administration or a
permit from the U.S. Army Corps of Engineers (Corps)).
If USFWS determines that Critical Habitat will be adversely modified or destroyed from a proposed action,
the USFWS will develop reasonable and prudent alternatives in cooperation with the federal institution to
ensure the purpose of the proposed action can be achieved without loss of Critical Habitat. If the action is
not likely to adversely modify or destroy Critical Habitat, USFWS will include a statement in its biological
opinion concerning any incidental take that may be authorized and specify terms and conditions to ensure
the agency is in compliance with the opinion.
Migratory Bird Treaty Act
The Migratory Bird Treaty Act (MBTA) (16 U.S. Government Code [USC] 703) makes it unlawful to
pursue, capture, kill, possess, or attempt to do the same to any migratory bird or part, nest, or egg of any
such bird listed in wildlife protection treaties between the United States, Great Britain, Mexico, Japan, and
the countries of the former Soviet Union, and authorizes the U.S. Secretary of the Interior to protect and
regulate the taking of migratory birds. It establishes seasons and bag limits for hunted species and protects
migratory birds, their occupied nests, and their eggs (16 USC 703; 50 CFR 10, 21).
Appendix E – Regulations
The MBTA covers the taking of any nests or eggs of migratory birds, except as allowed by permit pursuant
to 50 CFR, Part 21. Disturbances causing nest abandonment and/or loss of reproductive effort (i.e., killing
or abandonment of eggs or young) may also be considered “take.” This regulation seeks to protect migratory
birds and active nests.
In 1972, the MBTA was amended to include protection for migratory birds of prey (e.g., raptors). Six
families of raptors occurring in North America were included in the amendment: Accipitridae (kites, hawks,
and eagles); Cathartidae (New World vultures); Falconidae (falcons and caracaras); Pandionidae (ospreys);
Strigidae (typical owls); and Tytonidae (barn owls). The provisions of the 1972 amendment to the MBTA
protects all species and subspecies of the families listed above. The MBTA protects over 800 species
including geese, ducks, shorebirds, raptors, songbirds and many relatively common species.
State Regulations
California Environmental Quality Act (CEQA)
The California Environmental Quality Act (CEQA) provides for the protection of the environment within
the State of California by establishing State policy to prevent significant, avoidable damage to the
environment through the use of alternatives or mitigation measures for projects. It applies to actions directly
undertaken, financed, or permitted by State lead agencies. If a project is determined to be subject to CEQA,
the lead agency will be required to conduct an Initial Study (IS); if the IS determines that the project may
have significant impacts on the environment, the lead agency will subsequently be required to write an
Environmental Impact Report (EIR). A finding of non-significant effects will require either a Negative
Declaration or a Mitigated Negative Declaration instead of an EIR. Section 15380 of the CEQA Guidelines
independently defines “endangered” and “rare” species separately from the definitions of the California
Endangered Species Act (CESA). Under CEQA, “endangered” species of plants or animals are defined as
those whose survival and reproduction in the wild are in immediate jeopardy, while “rare” species are
defined as those who are in such low numbers that they could become endangered if their environment
worsens.
California Endangered Species Act (CESA)
In addition to federal laws, the state of California implements the CESA which is enforced by CDFW. The
CESA program maintains a separate listing of species beyond the FESA, although the provisions of each
act are similar.
State-listed threatened and endangered species are protected under provisions of the CESA. Activities that
may result in “take” of individuals (defined in CESA as; “hunt, pursue, catch, capture, or kill, or attempt to
hunt, pursue, catch, capture, or kill”) are regulated by CDFW. Habitat degradation or modification is not
included in the definition of “take” under CESA. Nonetheless, CDFW has interpreted “take” to include the
destruction of nesting, denning, or foraging habitat necessary to maintain a viable breeding population of
protected species.
The State of California considers an endangered species as one whose prospects of survival and
reproduction are in immediate jeopardy. A threatened species is considered as one present in such small
numbers throughout its range that it is likely to become an endangered species in the near future in the
Appendix E – Regulations
absence of special protection or management. A rare species is one that is considered present in such small
numbers throughout its range that it may become endangered if its present environment worsens. State
threatened and endangered species are fully protected against take, as defined above.
The CDFW has also produced a species of special concern list to serve as a species watch list. Species on
this list are either of limited distribution or their habitats have been reduced substantially, such that a threat
to their populations may be imminent. Species of special concern may receive special attention during
environmental review, but they do not have formal statutory protection. At the federal level, USFWS also
uses the label species of concern, as an informal term that refers to species which might be in need of
concentrated conservation actions. As the Species of Concern designated by USFWS do not receive formal
legal protection, the use of the term does not necessarily ensure that the species will be proposed for listing
as a threatened or endangered species.
Fish and Game Code
Fish and Game Code Sections 3503, 3503.5, 3511, and 3513 are applicable to natural resource management.
For example, Section 3503 of the Code makes it unlawful to destroy any birds’ nest or any birds’ eggs that
are protected under the MBTA. Further, any birds in the orders Falconiformes or Strigiformes (Birds of
Prey, such as hawks, eagles, and owls) are protected under Section 3503.5 of the Fish and Game Code
which makes it unlawful to take, possess, or destroy their nest or eggs. A consultation with CDFW may be
required prior to the removal of any bird of prey nest that may occur on a project site. Section 3511 of the
Fish and Game Code lists fully protected bird species, where the CDFW is unable to authorize the issuance
of permits or licenses to take these species. Pertinent species that are State fully protected by the State
include golden eagle (Aquila chrysaetos) and white-tailed kite (Elanus leucurus). Section 3513 of the Fish
and Game Code makes it unlawful to take or possess any migratory nongame bird as designated in the
MBTA or any part of such migratory nongame bird except as provided by rules and regulations adopted by
the Secretary of the Interior under provisions of the MBTA.
Native Plant Protection Act
Sections 1900–1913 of the Fish and Game Code were developed to preserve, protect, and enhance Rare
and Endangered plants in the state of California. The act requires all state agencies to use their authority to
carry out programs to conserve Endangered and Rare native plants. Provisions of the Native Plant
Protection Act prohibit the taking of listed plants from the wild and require notification of the CDFW at
least ten days in advance of any change in land use which would adversely impact listed plants. This allows
the CDFW to salvage listed plant species that would otherwise be destroyed.
California Native Plant Society Rare and Endangered Plant Species
Vascular plants listed as rare or endangered by the CNPS, but which have no designated status under FESA

Appendix E – Regulations
There are three key agencies that regulate activities within inland streams, wetlands, and riparian areas in
California. The Corps Regulatory Branch regulates activities pursuant to Section 404 of the Federal Clean
Water Act (CWA) and Section 10 of the Rivers and Harbors Act. Of the State agencies, the CDFG regulates
activities under the Fish and Game Code Section 1600-1616, and the Regional Board regulates activities
pursuant to Section 401 of the CWA and the California Porter-Cologne Water Quality Control Act.
Federal Regulations
Section 404 of the Clean Water Act
In accordance with the Revised Definition of “Waters of the United States”; Conforming (September 8,
2023), “waters of the United Sates” are defined as follows:
(a) Waters of the United States means:
(1) Waters which are:
(i) Currently used, or were used in the past, or may be susceptible to use in interstate or foreign
commerce, including all waters which are subject to the ebb and flow of the tide;
(ii) The territorial seas; or
(iii) Interstate waters;
(2) Impoundments of waters otherwise defined as waters of the United States under this definition,
other than impoundments of waters identified under paragraph (a)(5) of this section;
(3) Tributaries of waters identified in paragraph (a)(1) or (2) of this section that are relatively
permanent, standing or continuously flowing bodies of water;
(4) Wetlands adjacent to the following waters:
(i) Waters identified in paragraph (a)(1) of this section; or
(ii) Relatively permanent, standing or continuously flowing bodies of water identified in paragraph
(a)(2) or (a)(3) of this section and with a continuous surface connection to those waters;
(5) Intrastate lakes and ponds not identified in paragraphs (a)(1) through (4) of this section that are
relatively permanent, standing or continuously flowing bodies of water with a continuous surface
connection to the waters identified in paragraph (a)(1) or (a)(3) of this section
(b) The following are not “waters of the United States” even where they otherwise meet the terms of
paragraphs (a)(2) through (5) of this section:
(1) Waste treatment systems, including treatment ponds or lagoons, designed to meet the
requirements of the Clean Water Act;
(2) Prior converted cropland designated by the Secretary of Agriculture. The exclusion would cease
upon a change of use, which means that the area is no longer available for the production of
agricultural commodities. Notwithstanding the determination of an area's status as prior converted
Appendix E – Regulations
cropland by any other Federal agency, for the purposes of the Clean Water Act, the final authority
regarding Clean Water Act jurisdiction remains with EPA;
(3) Ditches (including roadside ditches) excavated wholly in and draining only dry land and that do
not carry a relatively permanent flow of water;
(4) Artificially irrigated areas that would revert to dry land if the irrigation ceased;
(5) Artificial lakes or ponds created by excavating or diking dry land to collect and retain water and
which are used exclusively for such purposes as stock watering, irrigation, settling basins, or rice
growing;
(6) Artificial reflecting or swimming pools or other small ornamental bodies of water created by
excavating or diking dry land to retain water for primarily aesthetic reasons;
(7) Waterfilled depressions created in dry land incidental to construction activity and pits excavated
in dry land for the purpose of obtaining fill, sand, or gravel unless and until the construction or
excavation operation is abandoned and the resulting body of water meets the definition of waters of
the United States; and
(8) Swales and erosional features (e.g., gullies, small washes) characterized by low volume,
infrequent, or short duration flow.
(c) In this section, the following definitions apply:
(1) Wetlands means those areas that are inundated or saturated by surface or ground water at a
frequency and duration sufficient to support, and that under normal circumstances do support, a
prevalence of vegetation typically adapted for life in saturated soil conditions. Wetlands generally
include swamps, marshes, bogs, and similar areas.
(2) Adjacent means having a continuous surface connection
(3) High tide line means the line of intersection of the land with the water's surface at the maximum
height reached by a rising tide. The high tide line may be determined, in the absence of actual data, by
a line of oil or scum along shore objects, a more or less continuous deposit of fine shell or debris on
the foreshore or berm, other physical markings or characteristics, vegetation lines, tidal gages, or
other suitable means that delineate the general height reached by a rising tide. The line encompasses
spring high tides and other high tides that occur with periodic frequency but does not include storm
surges in which there is a departure from the normal or predicted reach of the tide due to the piling up
of water against a coast by strong winds such as those accompanying a hurricane or other intense
storm.
(4) Ordinary high water mark means that line on the shore established by the fluctuations of water
and indicated by physical characteristics such as clear, natural line impressed on the bank, shelving,
changes in the character of soil, destruction of terrestrial vegetation, the presence of litter and debris,
or other appropriate means that consider the characteristics of the surrounding areas.
Appendix E – Regulations
(5) Tidal waters means those waters that rise and fall in a predictable and measurable rhythm or cycle
due to the gravitational pulls of the moon and sun. Tidal waters end where the rise and fall of the
water surface can no longer be practically measured in a predictable rhythm due to masking by
hydrologic, wind, or other effects.
Section 401 of the Clean Water Act
Pursuant to Section 401 of the CWA, any applicant for a federal license or permit to conduct any activity
which may result in any discharge to waters of the United States must provide certification from the State
or Indian tribe in which the discharge originates. This certification provides for the protection of the
physical, chemical, and biological integrity of waters, addresses impacts to water quality that may result
from issuance of federal permits, and helps insure that federal actions will not violate water quality
standards of the State or Indian tribe. In California, there are nine Regional Water Quality Control Boards
(Regional Board) that issue or deny certification for discharges to waters of the United States and waters of
the State, including wetlands, within their geographical jurisdiction. The State Water Resources Control
Board assumed this responsibility when a project has the potential to result in the discharge to waters within
multiple Regional Boards.
State Regulations
Fish and Game Code
Fish and Game Code Sections 1600 et. seq. establishes a fee-based process to ensure that projects conducted
in and around lakes, rivers, or streams do not adversely impact fish and wildlife resources, or, when adverse
impacts cannot be avoided, ensures that adequate mitigation and/or compensation is provided.
Fish and Game Code Section 1602 requires any person, state, or local governmental agency or public utility
to notify the CDFW before beginning any activity that will do one or more of the following:
(1) substantially obstruct or divert the natural flow of a river, stream, or lake;
(2) substantially change or use any material from the bed, channel, or bank of a river, stream, or lake;
or
(3) deposit or dispose of debris, waste, or other material containing crumbled, flaked, or ground
pavement where it can pass into a river, stream, or lake.
Fish and Game Code Section 1602 applies to all perennial, intermittent, and ephemeral rivers, streams, and
lakes in the State. CDFW’s regulatory authority extends to include riparian habitat (including wetlands)
supported by a river, stream, or lake regardless of the presence or absence of hydric soils and saturated soil
conditions. Generally, the CDFW takes jurisdiction to the top of bank of the stream or to the outer limit of
the adjacent riparian vegetation (outer drip line), whichever is greater. Notification is generally required
for any project that will take place in or in the vicinity of a river, stream, lake, or their tributaries. This
includes rivers or streams that flow at least periodically or permanently through a bed or channel with banks
that support fish or other aquatic life and watercourses having a surface or subsurface flow that support or
have supported riparian vegetation. A Section 1602 Streambed Alteration Agreement would be required if
impacts to identified CDFW jurisdictional areas occur.
Appendix E – Regulations
Porter Cologne Act
The California Porter-Cologne Water Quality Control Act gives the State very broad authority to regulate
waters of the State, which are defined as any surface water or groundwater, including saline waters. The
Porter-Cologne Act has become an important tool in the post SWANCC and Rapanos regulatory
environment, with respect to the state’s authority over isolated and insignificant waters. Generally, any
person proposing to discharge waste into a water body that could affect its water quality must file a Report
of Waste Discharge in the event that there is no Section 404/401 nexus. Although “waste” is partially
defined as any waste substance associated with human habitation, the Regional Board also interprets this
to include fill discharged into water bodies.
