INTRODUCTION
The following biological resources technical report describes a detailed assessment of
potential sensitive natural resources located within and/or immediately adjacent to the
Almond Avenue Trailer Yard project site (Project Site). The report has been prepared to
support compliance with the California Environmental Quality Act (CEQA) documentation
including the preparation of an Initial Study (IS), Environmental Impact Report (EIR) or
Mitigated negative Declaration (MND) and environmental review process conducted by
the City of Fontana. As discussed below, the assessment included a thorough literature
review, site reconnaissance characterizing existing conditions (including floral, faunal and
dominant vegetation communities), impact analysis, and applicable standards and
regulations to ensure impacts remain at a level below significance.
PROJECT SITE LOCATION
The Project Site is located within the City of Fontana, San Bernardino County, California
within Assessor Parcel Number (APN) 0234-061-04, totaling 9.50-acres, as shown in
Figure 1, Regional Location Map and Figure 2, Project Site Map. Specifically, the Project
Site extends west of Almond Avenue and south of Unincorporated San Bernardino
County.
PROJECT SITE DESCRIPTION
The proposed action includes the use of the entire property as a trailer yard storage area.
METHODOLOGY
The following section details the methods implemented prior to and during the
reconnaissance survey conducted throughout the Project Site.
LITERATURE REVIEW
Existing biological resource conditions within and adjacent to the Project Site were initially
investigated through review of pertinent scientific literature and industry standard
databases including but not limited to the following:
• California Native Plant Society (CNPS) Inventory of Rare and Endangered Plants in
California (CNPS 2025)
• United States Fish and Wildlife Service (USFWS) Species Occurrence Database
(USFWS 2025a)
• The Information for Planning and Consultation (IPaC) database from the USFWS
(USFWS 2025b) .
• USFWS Critical Habitat Mapper (USFWS 2025c)
The California Natural Diversity Database (CNDDB) (CDFW 2025a), a California
Department of Fish and Wildlife (CDFW) Natural Heritage Division species account
database.

• eBird (eBird 2025)
• City of Fontana Municipal Codes (City of Fontana 2025)
• City of Fontana General Plan 2015-2035 (City of Fontana 2018)
FIELD SURVEY
A reconnaissance survey of the Project Site was conducted by Ruben Ramirez of Cadre
Environmental on March 10th, 2025 in order to characterize and identify potential sensitive
plant and wildlife habitats, and to establish the accuracy of the data identified in the
literature search. Geologic and soil maps were examined to identify local soil types that
may support sensitive taxa. Aerial photograph, topographic maps, vegetation and rare
plant maps prepared for previous studies in the region were used to determine community
types and other physical features that may support sensitive plants/wildlife, uncommon
taxa, or rare communities that occur within or adjacent to the. Habitat assessments were
conducted for, but not limited to, the following target species/groups.
• Delhi sands flower loving fly – Federally Endangered (FE)
• Crotch’s bumble bee – State Candidate Endangered (SCE)
• Coastal California gnatcatcher – Federally Threatened (FT)/State Species of Special
Concern (SSC)
• Burrowing owl - SCE
• Least Bell’s vireo – FE/State Endangered (SE)
• San Bernardino kangaroo rat – FE/SSC
• Common and sensitive bat species
• Sensitive plants (Refer to Table 2, Sensitive Plant Species Assessment)
Vegetation Communities/Habitat Classification Mapping
Natural community names and hierarchical structure follows the “Manual of California
Vegetation Online” (CNPS 2025) classification system, which has been refined and
augmented where appropriate to better characterize the habitat types observed
throughout the Project Site. All plants observed during the survey efforts were either
identified in the field or collected and later identified using taxonomic keys. Plant
taxonomy follows Jepson Flora Project (eds.) (Jepson eFlora 2025). Scientific names are
included only at the first mention of a species; thereafter, common names alone are used.
Wildlife Resources Inventory
All animals identified during the reconnaissance survey by sight, call, tracks, scat, or other
characteristic sign were documented. In addition to species actually detected, expected
use of the site by other wildlife was derived from the analysis of habitats on the site,
combined with known habitat preferences of regionally occurring wildlife species.
Vertebrate taxonomy followed in this report is according to the Center for North American
Biological Resources Technical Report Almond Avenue Trailer Yard Project Site

Herpetology (2025 for amphibians and reptiles), the American Ornithological Society
(American Ornithological Society 2025) for birds, and American Society of Mammalogists
(2025) for mammals. Both common and scientific names are used during the first mention
of a species; common names only are used in the remainder of the text.
Jurisdictional Resources Assessment
The Project Site was assessed for the potential presence/absence of United States Army
Corps of Engineers (USACE), CDFW, and Regional Water Quality Control Board
(RWQCB) jurisdictional resources through review of pertinent scientific literature and
industry standard databases including but not limited to the following:
• Custom Soil Resources Report for San Bernardino County, California. (Natural
Resources Conservation Service (NRCS) U.S. Department of Agriculture (USDA)
2025)
• National Wetlands Mapper (NWI) (USFWS 2025d)
• National Surface Water Information System Database. United States Geological
Service (USGS 2025).
• Corps of Engineers Wetlands Delineation Manual, Technical Report (Environmental
Laboratory. 1987).
• Regional Supplement to the USACE of Engineers Wetland Delineation Manual:
Arid West Region (USACE 2008).
• Final National Ordinary High Water Mark Field Delineation Manual for Rivers and
Streams (USACE 2025).
EXISTING ENVIRONMENTAL SETTING
The following section presents the existing conditions of the Project Site. The entire
Project Site is characterized as developed by the Jensen Precast Concrete Manufacturing
Facility, as shown in Figure 3, Vegetation Communities Map, and Figure 4 Current Project
Site Photograph, and outlined in Table 1, Project Site Vegetation Community Acreages.
The Project Site is bordered by high traffic roads and industrial development. The Soil
Survey of the San Bernardino County Area has the Project Site mapped as Tujunga
gravelly loamy sand, 0 to 9 percent slope substrates (TvC) and Quarries and Pits soils
(QP), as shown on Figure 5, Soils Association Map.
VEGETATION COMMUNITIES

GENERAL PLANT & WILDIFE SPECIES
The Project Site is devoid of vegetation.
General wildlife species documented within or adjacent to the Project Site include rock
dove (Columba livia), mourning dove (Zenaida macroura), black phoebe (Sayornis
nigricans), Say’s phoebe (Sayornis saya), American crow (Corvus brachyrhynchos),
European starling (Sturnus vulgaris), and house finch (Haemorhous mexicanus).
JURISDICTIONAL RESOURCES
No jurisdictional resources regulated by the USACE, CDFW, or RWQCB are present
within or adjacent to the Project Site. Impacts to water quality would be less than
significant during both construction and operation following preparation and
implementation of a Water Quality Management Plan (WQMP), Storm Water Pollution
Prevention Plan (SWPPP) and compliance with the City of Fontana Storm Water
Program/National Pollutant Discharge Elimination System (NPDES) permit and Area-
Wide Urban Storm Water Runoff Management Program Municipal Separate Stormwater
Sewer System (MS4s) code provisions.
SENSITIVE BIOLOGICAL RESOURCES
The following discussion describes the plant and wildlife species present, or potentially
present within the property boundaries, that have been afforded special recognition by
federal, state, or local resource conservation agencies and organizations, principally due
to the species’ declining or limited population sizes, usually resulting from habitat loss.
Also discussed are habitats that are unique, of relatively limited distribution, or of
particular value to wildlife. Protected sensitive species are classified by state and/or
federal resource management agencies, or both, as threatened or endangered, under
provisions of the state and federal endangered species act.
Sensitive biological resources are habitats or individual species that have special
recognition by federal, state, or local conservation agencies and organizations as
endangered, threatened, or rare. The CDFW, USFWS, and special groups like the CNPS
maintain watch lists of such resources. For the purpose of this assessment sources used
to determine the sensitive status of biological resources are:
Plants: USFWS (2025a), CNDDB (CDFW 2025a), CDFW (2025d, 2025e),
CNPS (2025a),

(2012, 2025b, 2025c, 2025f).
Habitats: CNDDB (CDFW 2025a, 2025f).
FEDERAL PROTECTION AND CLASSIFICATIONS
The Federal Endangered Species Act of 1973 (FESA) defines an endangered species as
“any species that is in danger of extinction throughout all or a significant portion of its
range... (USFWS 1973)” Threatened species are defined as “any species which is likely
to become an endangered species within the foreseeable future throughout all or a
significant portion of its range.” Under provisions of Section 9(a)(1)(B) of the FESA it is
unlawful to “take” any listed species. “Take” is defined as follows in Section 3(18) of the
FESA: “...harass, harm, pursue, hunt, shoot, wound, kill, trap, capture, or collect, or to
attempt to engage in any such conduct.” Further, the USFWS, through regulation, has
interpreted the terms “harm” and “harass” to include certain types of habitat modification
as forms of a “take.” These interpretations, however, are generally considered and
applied on a case-by-case basis and often vary from species to species. In a case where
a property owner seeks permission from a federal agency for an action that could affect
a federally listed plant and animal species, the property owner and agency are required
to consult with USFWS. This term is employed in this document but carries no official
protections. All references to federally protected species in this report (whether listed,
proposed for listing or candidate) include the most current published status or candidate
category to which each species has been assigned by USFWS. For purposes of this
assessment, the following acronyms are used for federal status species:
FE Federal Endangered
FT Federal Threatened
FPE Federal Proposed Endangered
FPT Federal Proposed Threatened
FC Federal Candidate for Listing
The designation of critical habitat can also have a significant impact on the development
of land designated as “critical habitat.” The FESA prohibits federal agencies from taking
any action that will “adversely modify or destroy” critical habitat (16 U.S.C. § 1536(a)(2)).
This provision of the FESA applies to the issuance of permits by federal agencies. Before
approving an action affecting critical habitat, the federal agency is required to consult with
the USFWS who then issues a biological opinion evaluating whether the action will
“adversely modify” critical habitat. Thus, the designation of critical habitat effectively gives
the USFWS extensive regulatory control over the development of land designated as
critical habitat.
Biological Resources Technical Report Almond Avenue Trailer Yard Project Site
Cadre Environmental November 2025

The Migratory Bird Treaty Act of 1918 (MBTA) makes it unlawful to “take” any migratory
bird or part, nest, or egg of such bird listed in wildlife protection treaties between the
United States and Great Britain, the Republic of Mexico, Japan, and the Union of Soviet
States (USFWS 1918, 2024). For purposes of the MBTA, “take” is defined as to pursue,
hunt, capture, kill, or possess or attempt to do the same.
The Bald Eagle and Golden Eagle Protection Act explicitly protects the bald eagle and
golden eagle and imposes its own prohibition on any taking of these species (USFWS
1940). As defined in this act, take means to pursue, shoot, shoot at, poison, wound, kill,
capture, trap, collect, or molest or disturb. Current USFWS policy is not to refer the
incidental take of bald eagles for prosecution under the Bald Eagle and Golden Eagle
Protection Act (16 U.S.C. 668-668d).
STATE PROTECTION AND CLASSIFICATIONS
California's Endangered Species Act (CESA) defines an endangered species as “...a
native species or subspecies of a 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” (California Fish and Game Commission 1997). The
State defines a threatened species as “...a native species or subspecies of a 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 by this chapter. Any
animal determined by the commission as rare on or before January 1, 1985 is a
threatened species.” Candidate species are defined as “...a native species or subspecies
of a bird, mammal, fish, amphibian, reptile, or plant that the commission has formally
noticed as being under review by the department for addition to either the list of
endangered species or the list of threatened species, or a species for which the
commission has published a notice of proposed regulation to add the species to either
list.” Candidate species may be afforded temporary protection as though they were
already listed as threatened or endangered at the discretion of the Fish and Game
Commission.
Article 3, Sections 2080 through 2085, of CESA addresses the taking of threatened or
endangered species by stating “No person shall import into this state, export out of this
state, or take, possess, purchase, or sell within this state, any species, or any part or
product thereof, that the commission determines to be an endangered species or a
threatened species, or attempt any of those acts, except as otherwise provided...” Under
CESA, “take” is defined as “...hunt, pursue, catch, capture, or kill, or attempt to hunt,
pursue, catch, capture, or kill.” Exceptions authorized by the state to allow “take” require
“...permits or memorandums of understanding...” and can be authorized for
“...endangered species, threatened species, or candidate species for scientific,
educational, or management purposes.” Sections 1901 and 1913 of the California Fish
and Game Code provide that notification is required prior to disturbance.
Additionally, some sensitive mammals and birds are protected by the State as Fully
Protected Mammals or Fully Protected Birds, as described in the California Fish and
Game Code, Sections 4700 and 3511, respectively. SSC (“special” animals and plants)

listings include special status species, including all state and federal protected and
candidate taxa, Bureau of Land Management (BLM) and US Forest Service (USFS)
sensitive species, species considered to be declining or rare by the CNPS or National
Audubon Society, and a selection of species which are considered to be under population
stress but are not formally proposed for listing. This list is primarily a working document
for the CDFW's CNDDB project. Informally listed taxa are not protected per se, but
warrant consideration in the preparation of biotic assessments. For some species, the
CNDDB is only concerned with specific portions of the life history, such as roosts,
rookeries, or nest sites. For the purposes of this assessment, the following acronyms
are used for State status species:
SE State Endangered
ST State Threatened
SCE State Candidate Endangered
SCT State Candidate Threatened
SFP State Fully Protected
SP State Protected
SR State Rare
SSC California Species of Special Concern
CWL California Watch List
Nesting birds, including raptors, are protected under California Fish and Game Code
Section 3503, which reads, “It is unlawful to take, possess, or needlessly destroy the nest
or eggs of any bird, except as otherwise provided by this code or any regulation made
pursuant thereto.” In addition, under California Fish and Game Code Section 3503.5, “it
is unlawful to take, possess, or destroy any birds in the orders Falconiformes or
Strigiformes (birds-of-prey) or to take, possess, or destroy the nest or eggs of any such
bird except as otherwise provided by this code or any regulation adopted pursuant
thereto”. Passerines and non-passerine land birds are further protected under California
Fish and Game Code 3513. As such, CDFW typically recommends surveys for nesting
birds that could potentially be directly (e.g., actual removal of trees/vegetation) or
indirectly (e.g., noise disturbance) impacted by project-related activities. Disturbance
during the breeding season could result in the incidental loss of fertile eggs or nestlings,
or otherwise lead to nest abandonment. Disturbance that causes nest abandonment
and/or loss of reproductive effort is considered “take” by CDFW.
The CNPS is a private plant conservation organization dedicated to the monitoring and
protection of sensitive species in the State. This organization has compiled an inventory
comprised of the information focusing on geographic distribution and qualitative
characterization of rare, threatened, or endangered vascular plant species of California
(Tibor 2001). The list serves as the candidate list for listing as threatened and
endangered by CDFW. The CNPS has developed five categories of rarity (CRPR):
CRPR 1A Plants presumed extirpated in California and either rare or
extinct elsewhere
Biological Resources Technical Report Almond Avenue Trailer Yard Project Site
Cadre Environmental November 2025
13
CRPR 1B Rare, threatened, or endangered in California and elsewhere
CRPR 2A Plants presumed extirpated in California but common elsewhere
CRPR 2B Plants rare, threatened, or endangered in California but more
common elsewhere
CRPR 3 Plants about which we need more information – a review list
CRPR 4
Species of limited distribution in California (i.e., naturally rare in
the wild), but whose existence does not appear to be
susceptible to threat
As stated by the CNPS:
“Threat Rank is an extension added onto the California Rare Plant Rank
and designates the level of endangerment by a 1 to 3 ranking with 1 being
the most endangered and 3 being the least endangered. A Threat Rank is
present for all California Rare Plant Rank 1B's, 2's, 4's, and the majority of
California Rare Plant Rank 3's. California Rare Plant Rank 4 plants are
seldom assigned a Threat Rank of 0.1, as they generally have large enough
populations to not have significant threats to their continued existence in
California; however, certain conditions exist to make the plant a species of
concern and hence be assigned a California Rare Plant Rank. In addition,
all California Rare Plant Rank 1A (presumed extinct in California), and some
California Rare Plant Rank 3 (need more information) plants, which lack
threat information, do not have a Threat Rank extension.” (CNPS 2025)
0.1 Seriously threatened in California (over 80% of occurrences
threatened / high degree and immediacy of threat)
0.2 Fairly threatened in California (20-80% occurrences threatened /
moderate degree and immediacy of threat)
0.3
Not very threatened in California (<20% of occurrences
threatened / low degree and immediacy of threat or no current
threats known)
LOCAL PROTECTION AND CLASSIFICATIONS
Fontana Municipal Code - Regulated Trees
The City of Fontana’s Municipal Code Chapter 28, Article III (Ord. No. 1126, § 1, 8-16-94)
requires the preservation and protection of heritage, significant and/or specimen trees
within both private and public property. No trees regulated by the City of Fontana’s
Municipal Code Chapter 28, Article III (Ord. No. 1126, § 1, 8-16-94) were documented
onsite within the City’s boundaries. No Impact.
SENSITIVE HABITATS
As stated by CDFW:

“One purpose of the vegetation classification is to assist in determining the
level of rarity and imperilment of vegetation types. Ranking of alliances
according to their degree of imperilment (as measured by rarity, trends, and
threats) follows NatureServe’s Heritage Methodology, in which all alliances
are listed with a G (global) and S (state) rank. For alliances with State ranks
of S1-S3, all associations within them are also considered to be highly
imperiled”. (CDFW 2025f)
No sensitive habitats were documented within the Project Site. The Project Site is
characterized as developed habitat.
SENSITIVE PLANTS
Based on a review of the CNDDB, City of Fontana General Plan and existing conditions
within and adjacent to the Project Site, a total of twenty-four (24) sensitive plant species
have potential to occur within the region of the property, as presented in Table 2, Sensitive
Plant Species Assessment.

ENVIRONMENTAL IMPACTS
The following section includes an analysis of the direct and/or indirect impacts of the
proposed action on sensitive biological resources. This analysis characterizes the project
related activities that are anticipated to adversely impact the species, and when feasible,
quantifies such impacts. Direct effects are defined as actions that may cause an
immediate effect on the species or its habitat, including the effects of interrelated actions
and interdependent actions. Indirect effects are caused by or result from the proposed
actions, are later in time, and are reasonably certain to occur. Indirect effects may occur
outside of the area directly affected by the proposed action.

THRESHOLD OF SIGNIFICANCE
The environmental impacts relative to biological resources are assessed using impact
significance criteria which mirror the policy statement contained in the CEQA at Section
21001 (c) of the Public Resources Code. This section reflects that the legislature has
established it to be the policy of the state to:
“Prevent the elimination of fish and wildlife species due to man’s activities,
ensure that fish and wildlife populations do not drop below self-perpetuating
levels, and preserve for future generations representations of all plant and
animal communities…”
The following definitions apply to the significance criteria for biological resources:
• “Endangered” means that the species is listed as endangered under state or federal
law.
• “Threatened” means that the species is listed as threatened under state or federal law.
• “Rare” means that the species exists in such small numbers throughout all or a
significant portion of its range that it may become endangered if its environment
worsens.
• “Region” refers to the area within southern California that is within the range of the
individual species.
• “Sensitive habitat” refers to habitat for plants and animals (1) which plays a special
role in perpetuating species utilizing the habitat on the property, and (2) without which
there would be substantial danger that the population of that species would drop below
self-perpetuating levels.
• “Substantial effect” means significance loss or harm of a magnitude which, based on
current scientific data and knowledge, (1) would cause a species or a native plant or
animal community to drop below self-perpetuating levels on a statewide or regional
basis or (2) would cause a species to become threatened or endangered.
Also, the determination of impacts has been made according to the federal definition of
“take”. FESA prohibits the “taking” of a member of an endangered or threatened wildlife
species or removing, damaging, or destroying a listed plant species by any person
(including private individuals and private or government entities). FESA defines “take” as
“to harass, harm, pursue, hunt, shoot, would, kill, trap, capture or collect” an endangered
or threatened species, or to attempt to engage in these activities.

a) Have a substantial adverse effect, either directly or through habitat modifications,
on any species identified as a candidate, sensitive, or special status species in
local or regional plans, policies, or regulations, or by the CDFW or USFWS?
No Impact. No suitable habitat for sensitive plant species including those listed as federal
or state threatened/endangered was documented within the Project Site. No sensitive
plant species listed in Table 2, Sensitive Plant Species Assessment or suitable habitats
or soils were documented within the Project Site. No suitable habitat for sensitive
invertebrate or wildlife species including those listed as federal or state
threatened/endangered was documented within the Project Site. No sensitive wildlife
species listed in Table 3, Sensitive Wildlife Species Assessment or suitable habitats or
soils were documented within the Project Site. The entire Project Site is developed and
is currently operating as an active concrete manufacturing facility including, storage and
staging areas.
b) Have a substantial adverse effect on any riparian habitat or other sensitive natural
community identified in local or regional plans, policies, regulations, or by CDFW
or USFWS?
No Impact. A total of 9.50-acres of developed lands within the Project Site will be directly
and permanently impacted as a result of project implementation, as summarized in Table
4, Vegetation Community Impacts, and illustrated on Figure 6, Project Site Impact Map.
No riparian or sensitive habitat identified in local or regional plans, policies, regulations,
or by CDFW or USFWS will be impacted as a result of project initiation.

c) Have a substantial adverse effect on federally protected wetlands as defined by
Section 404 of the CWA (including, but not limited to, marsh, vernal pool, coastal,
etc.) through direct removal, filling, hydrological interruption, or other means?
No Impact. No jurisdictional resources regulated by the USACE, CDFW, or RWQCB are
present within or adjacent to the Project Site. Impacts to water quality would be less than
significant during both construction and operation following preparation and
implementation of a WQMP, SWPPP and compliance with the City of Fontana Storm
Water Program/NPDES permit and Area-Wide Urban Storm Water Runoff Management
Program Municipal Separate Stormwater Sewer System (MS4s) code provisions.
d) Interfere substantially with the movement of any native resident or migratory fish
or wildlife species or with established native resident or migratory wildlife corridors,
or impede the use of native wildlife nursery sites?

No Impact. No suitable habitat for nesting migratory birds protected under the MBTA
and the CDFG Code Sections 3503, 3503.5, and 3513 was documented onsite. The
Project Site is devoid of vegetation.
The Project Site is completely surrounded by high traffic roads, industrial development
and does not contribute or represent a local or regional wildlife movement corridor. No
Impact.
e) Conflict with any local policies or ordinances protecting biological resources, such
as a tree preservation policy or ordinance?
No Impact. No trees regulated by the City of Fontana’s Municipal Code Chapter 28, Article
III (Ord. No. 1126, § 1, 8-16-94) were documented onsite within the City’s boundaries. No
trees regulated by the County Development Code Division 8 “Resource Management and
Conservation”, Chapter 88.01 “Plant Protection and Management” were documented
onsite within the Counties boundaries.
f) Conflict with the provisions of an adopted Habitat Conservation Plan, Native
Community Conservation Plan, or other approved local, regional, or state habitat
conservation plan?
No Impact. The Project Site is not located within or adjacent to a Conservation Program
Area. Therefore, implementation of the project would not result in a conflict with the
provisions of an adopted habitat conservation plan and no impact would occur.
INDIRECT IMPACTS
To ensure that potential indirect adverse effects to sensitive species and resources are
reduced to a less than significant level, the following measures will be implemented.
Water Quality
Impacts to water quality would be less than significant during both construction and
operation following preparation of a WQMP, SWPPP and compliance with the City of
Fontana Storm Water Program/NPDES permit and Area-Wide Urban Storm Water
Runoff Management Program Municipal Separate Stormwater Sewer System
(MS4s) code provisions.
Toxics
Toxic sources within the Project Site would be limited to those commonly associated with
industrial developments such as pesticides, insecticides, herbicides, fertilizers, and
vehicle emissions. Impacts to water quality would be less than significant during both
construction and operation following preparation of a WQMP, SWPPP and compliance
with the City of Fontana Storm Water Program/NPDES permit and Area-Wide Urban
Storm Water Runoff Management Program Municipal Separate Stormwater Sewer
System (MS4s) code provisions.

Lighting
No impacts related to lighting would occur during both construction and operation. The
Project Site is not located adjacent to any conserved open space habitats or sensitive
biological resources. No impact.
Noise
No impacts to related to noise would occur during both construction and operation. The
Project Site is not located adjacent to any conserved open space habitats or sensitive
biological resources. No impact.
CUMULATIVE IMPACTS
The direct and/or indirect impacts of the project would not result in significant cumulative
impacts (CEQA Section 15310) to environmental resources within the region of the
Project Site. Cumulative impacts refer to incremental effects of an individual project when
assessed with the effects of past, current, and proposed projects. The project represents
the development of 9.50-acres of land already developed and surrounded by industrial
and high traffic roads, and therefore will not result in an adverse cumulative impact to
sensitive resources. Impacts related to buildout of the City of Fontana are anticipated to
be less than significant if projects comply with the City of Fontana General Plan 2015-
2035 policies principles/goals, and actions. Following implementation of the following
conservation measures, the proposed action would not conflict with the general plan
policies for the protection of sensitive resources.
CONSERVATION MEASURES
No conservation measures or conditions of approval are proposed or required.
