1.0 INTRODUCTION
Addendum to the
SWIP Specific Plan Update and Annexation PEIR Introduction
Almond Avenue Trailer Yard 1-1
1.0 INTRODUCTION
1.1 Project Overview
DLJ Fontana, LLC (hereinafter, “Project Applicant”) proposes to develop an approximately 9.49-acre site (Project
Site) as a trailer parking facility with associated site improvements. The Project Site is located on the west side of
Almond Avenue, south of San Bernardino Avenue. The Project Site consists of one (1) parcel including Assessor
Parcel Number (APN) 0234-061-04. The Project involves redevelopment of the Site by clearing the Site of existing
improvements and constructing and operating a trailer yard providing 250 trailer parking stalls (12 feet by 53 feet
each) and 39 passenger vehicle parking spaces, including one Americans with Disabilities Act (ADA)–accessible
space, for employees and visitors. Site improvements associated with the Project include, but are not limited to,
a 1,558-square-foot prefabricated office building, a 160-square-foot prefabricated guard shack at the entrance of
the Site, perimeter fencing and 14-foot-high screen walls, security lighting, landscaping, drainage facilities, and a
trash/recycling enclosure. The Project Applicant also would construct improvements to Almond Avenue along the
Project Site’s frontage and complete required utility connections consistent with City of Fontana standards.
1.2 California Environmental Quality Act
The California Environmental Quality Act (CEQA), a statewide environmental law contained in Public Resources
Code Sections 21000-21177, applies to most public agency decisions to carry out, authorize, or approve actions
that have the potential to adversely affect the environment. CEQA also gives other public agencies and the public
an opportunity to participate in the environmental review process.
1.2.1 Prior CEQA Compliance
The Project Site is located within the Southwest Industrial Park (SWIP) Specific Plan (SP) area. The City of Fontana
(hereinafter “City”) adopted the original SWIP SP in 1983. The SWIP SP was comprehensively updated in 2012,
which included the addition of 1,318 acres to the SWIP SP area (bringing the total SP area to 3,111 acres). The
SWIP SP establishes the overall vision and development plan for the SP area and acts as a bridge between the
City’s General Plan and individual development proposals. The SWIP SP combines development standards and
guidelines, capital improvement programs, and financing methods, which are tailored to meet the needs of the
SWIP SP area, into a single, comprehensive plan.
Potential environmental impacts associated with buildout of the SWIP SP were evaluated by the SWIP SP Update
and Annexation Program Environmental Impact Report (PEIR). The SWIP SP PEIR was prepared as a PEIR pursuant
to CEQA Guidelines Section 15168. As defined by CEQA Guidelines Section 15168, a PEIR is “…an EIR which may
be prepared on a series of actions that can be characterized as one large project and are related…”. The Fontana
City Council certified the PEIR on May 8, 2012 (State Clearinghouse [SCH] Number [No.] 2009091089; hereinafter
“SWIP SP PEIR”).
In certifying the SWIP SP PEIR, the City Council found that the SWIP SP PEIR adequately addressed the potential
environmental impacts associated with planned buildout of the SWIP SP area. The SWIP SP PEIR identified the
following seven (7) significant and unavoidable environmental impacts (identified as Impacts 4.1-1, 4.2-1, 4.2-2,
4.2-4, 4.7-3, 4.8-5, and 4.9-1) that would result from implementation of the SWIP SP:
Aesthetics: The SWIP SP PEIR found that buildout of the SWIP SP would result in significant and
unavoidable impacts to scenic vistas, because the long-term buildout of industrial, commercial, and office
Addendum to the
SWIP Specific Plan Update and Annexation PEIR Introduction
Almond Avenue Trailer Yard 1-2
uses would result in a significant alteration in views of the Jurupa Mountains to the south and the San
Gabriel/San Bernardino Mountains to the north.
Air Quality: The SWIP SP PEIR found that development within the SWIP SP would generate short-term
construction-related emissions of dust (particulate matter [PM]) and vehicle/equipment exhaust that
could exceed South Coast Air Quality Management (SCAQMD) thresholds which would result in a
significant and unavoidable impact. Additionally, the SWIP SP PEIR concluded long-term operations within
the SWIP SP area would generate emissions that would exceed SCAQMD daily thresholds for reactive
organic gases (ROGs), nitrogen oxides (NOX), carbon monoxide (CO), and particulate matter (PM10 and
PM2.5), resulting in a significant and unavoidable impact. Furthermore, the SWIP SP PEIR concluded that
because emissions associated with buildout of the SWIP SP would exceed SCAQMD thresholds, the
emissions from the SWIP SP would result in a conflict with the Air Quality Management Plan (AQMP).
Accordingly, the SWIP SP PEIR concluded that implementation of the SWIP SP would result in significant
and unavoidable short-term and long-term air quality impacts.
Noise: The SWIP SP PEIR determined that buildout of the SWIP SP would result in significant and
unavoidable mobile-source (traffic-related) noise impacts.
Public Services: The SWIP SP PEIR determined that implementation of the SWIP SP would generate
additional demand for parks and recreational facilities. However, no development impact fees for parks
and recreation facilities would be collected as part of the development of the SWIP SP because the SWIP
would only include non-residential land uses. Therefore, the SWIP SP PEIR concluded that a significant and
unavoidable impact would occur.
Transportation and Traffic: The SWIP SP PEIR determined that the SWIP SP’s addition of traffic would
result in deficient operations at 9 roadway segments and 19 intersections within the study area under the
Existing with Approved Project scenario and would contribute to deficient operations at 10 roadway
segments and 19 intersections under the Forecast Year 2030 with Project scenario. Because the City of
Fontana could not assure the installation of all needed traffic improvements, the SWIP SP PEIR concluded
that impacts to these facilities would be significant and unavoidable.
In conjunction with certifying the SWIP SP PEIR, the City Council adopted a Statement of Overriding
Considerations, which stated that the benefits of the SWIP SP outweighed the significant and unavoidable
environmental impacts summarized above.
1.2.2 CEQA Rules and Requirements for an Addendum
The CEQA Guidelines allow for the updating and re-use of the previously approved/certified CEQA document when
a subsequent project is within the scope of the analysis of the earlier approved CEQA document and when some
changes or additions to the original CEQA document are necessary but none of the following conditions are met:
a. Substantial changes are proposed in the project that will require major revisions of the previous EIR due
to the involvement of environmental effects or a substantial increase in the severity of previously
identified significant effects;
b. Substantial changes occur with respect to the circumstances under which the project is undertaken, which
will require major revisions of the previous EIR due to the involvement of new significant environmental
effects or a substantial increase in the severity of previously identified significant effects; or
Addendum to the
SWIP Specific Plan Update and Annexation PEIR Introduction
Almond Avenue Trailer Yard 1-3
c. New information of substantial importance, which was not known and could not have been known with
the exercise of reasonable diligence at the time the previous EIR was certified as complete, shows any of
the following:
1. The project will have one or more significant effects not discussed in the previous EIR;
2. Significant effects previously examined will be substantially more severe than shown in the previous
EIR;
3. MMs or alternatives previously found not to be feasible would in fact be feasible, and would
substantially reduce one or more significant effects of the project, but the project proponents decline
to adopt the MM or alternatives; or
4. MMs or alternatives which are considerably different from those analyzed in the previous EIR would
substantially reduce one or more significant effects on the environment, but the project proponents
decline to adopt the MM or alternative. (See CEQA Guidelines Section 15162).
If none of the circumstances listed above occur and only minor technical changes or additions are necessary to
update the previously approved/certified CEQA document, an Addendum may be prepared (See CEQA Guidelines
Section 15164).
1.2.3 Finding for the Project
The City, serving as the CEQA Lead Agency for the Project (See CEQA Guidelines Sections 15050–15051),
determined in its independent judgment that the Project does not meet any of the circumstances from CEQA
Guidelines Section 15162 and that an Addendum to the previously-certified SWIP SP PEIR is the appropriate CEQA
compliance document for the Project. The City’s finding is based on the following facts:
a. As demonstrated in detail in Section 4.0 of this document, the Project would not require major revisions
to the previously-certified SWIP SP PEIR because implementation of the Project would neither result in
any significant impacts to the physical environment that were not already disclosed in the SWIP SP PEIR
nor result in substantial increases in the severity of the environmental impacts previously disclosed in the
SWIP SP PEIR.
b. Subsequent to the certification of the SWIP SP PEIR, no substantial changes in the circumstances under
which the Project would be undertaken have occurred that would require major revisions to the SWIP SP
PEIR due to the involvement of new significant environmental effects or a substantial increase in the
severity of previously identified significant effects.
c. There is no evidence in the public record that new information of substantial importance has become
available that is applicable to the Project and/or Project Site, was not known and could not have been
known with the exercise of reasonable diligence at the time the SWIP SP PEIR was certified and would
alter the conclusions of the SWIP SP PEIR.

2.0 ENVIRONMENTAL SETTING
Addendum to the
SWIP Specific Plan Update and Annexation PEIR Environmental Setting
Almond Avenue Trailer Yard 2-1
2.0 ENVIRONMENTAL SETTING
2.1 Project Location
The Project Site is on the west side of Almond Avenue, approximately 1,242 feet south of San Bernardino Avenue
and 612 feet north of Valley Boulevard in the City of Fontana, San Bernardino County, California. The Project Site
is in the southwest portion of the City and is approximately 0.7 roadway miles northwest of the Cherry Avenue
on/off-ramps to Interstate 10 (I-10) and approximately 3 roadway miles east of the Fourth Street on/off-ramps to
Interstate 15 (I-15). The Project’s location is illustrated in Figure 2-1, Regional Map, Figure 2-2, Vicinity Map, and
Figure 2-3, USGS Topographic Map.
2.2 Existing Condition of Project Site
As shown on Figure 2-4 through Figure 2-6, the Project Site is currently developed, highly disturbed, and functions
as an outdoor industrial storage yard. The Site is used for the storage of precast concrete construction products
and related concrete products, including but not limited to pipes, catch basins, storage tanks, utility vaults, and
roadway barriers, associated with concrete manufacturing operations that are conducted on an adjacent (off-site)
property. Site conditions consist primarily of compacted dirt and gravel surfaces, and the Site is occupied by
numerous stacks and rows of concrete products, manufacturing components and forms, and related materials, as
well as truck parking/storage for heavy duty trucks used in connection with the operations. The Project Site
contains internal access drives and circulation areas used for material handling and vehicle access but there are
no existing connections to Almond Avenue. The Project Site is enclosed by approximately 6-foot-tall chain link
fencing topped with barbed wire.
2.3 Environmental Setting and Surrounding Land Uses
The Project area was historically used for agricultural land uses before transitioning to commercial/industrial land
uses; areas north of San Bernardino Avenue were primarily occupied by the Kaiser Steel Mill and developed in the
1940s while areas south of San Bernardino Avenue began transitioning to commercial and industrial land uses in
the 1980s. Existing land uses surrounding the Project Site include the following:
North: The property immediately north of the Project Site is occupied by Jensen Precast, an industrial facility
utilized for the manufacture and outdoor storage of precast concrete infrastructure products.
South: The properties immediately south of the Project Site are developed with truck-serving industrial uses,
including a truck wash facility and a truck fueling station.
East: The Project Site fronts Almond Avenue to the east. Directly across Almond Avenue, is a vacant property
that is approved for development with a 275,684-square-foot warehouse building, but has not yet
commenced construction. Other properties along the east side of Almond Avenue are developed with
industrial and logistics-related uses, including Prime Truck and Trailer Repair, Swift Transportation, and
other fleet maintenance and equipment storage facilities.
West: The property immediately west of the Project Site is occupied by IAA Fontana, an auto auction and vehicle
storage facility.

SWIP Specific Plan Update and Annexation PEIR Environmental Setting
Almond Avenue Trailer Yard 2-2
2.4 Existing General Plan and Zoning
The City of Fontana General Plan and SWIP SP are the prevailing long-range planning documents that pertain to
the Project Site. The City of Fontana General Plan Land Use Map identifies the Project Site as being within the
SWIP SP area and designates the Project Site for Light Industrial (I-L) land uses. The SWIP SP establishes the specific
zoning regulations, including development standards and design guidelines, for each of its nine (9) development
districts.
The Project Site is located within the Speedway Industrial District (SID), which encompasses approximately 126.2
acres within the northern portion of the SWIP SP. The SID is intended to promote the continued use and expansion
of industrial and logistics-based development by supporting warehousing, distribution, manufacturing, and
related service commercial uses. The SWIP Specific Plan anticipates that the SID area will largely redevelop with a
mixture of industrial, manufacturing, processing, warehousing, and logistics-based distribution uses, with
warehousing, distribution and other truck-related industrial uses as the primary planned uses in the area due to
its proximity to I-10. The SWIP SP assumes that almost the entirety of the SID area will be re-developed with only
31,508 s.f. of existing development to be retained and a maximum of 2,540,637 s.f. of new development (for a
total of 2,572,145 s.f. of building area within the SID area).

3.0 PROJECT DESCRIPTION
The Project evaluated by this EIR Addendum consists of two proposals: an Administrative Site Plan (City Case No.
ASP 25-0020) and a Conditional Use Permit (City Case No. CUP 25-0015). The proposed development actions are
collectively referred to as Master Case No. 25-0059. The application materials for the Project are herein
incorporated by reference pursuant to CEQA Guidelines Section 15150 and copies are available for review at the
City of Fontana Community Development Department, Planning Division, located at 8353 Sierra Avenue, Fontana,
California, 92335. The individual components of the Project are discussed below.
3.1 Project Components
3.1.1 Administrative Site Plan
Administrative Site Plan No. 25-0020 (ASP 25-0020) provides a development plan for the redevelopment of the
Project Site in conformance with the property’s General Plan land use designation “Light Industrial (I-L)” and SWIP
SP zoning designation (SID). ASP 25-0020 is designed to comply with all applicable design, screening, and
development standards of the Southwest Industrial Park Specific Plan (SWIP) and the Fontana Municipal Code.
ASP 25-0020 includes the following components:
A. Conceptual Site Plan
As illustrated on, Figure 3-1, Conceptual Site Plan, the Project is designed with trailer parking rows and internal
circulation aisles generally aligned with the parcel boundaries to facilitate efficient trailer storage and circulation.
Site access would be provided from Almond Avenue, which forms the eastern boundary of the Project Site. The
Project would provide a total of 250 trailer parking stalls (each trailer stall would be 12 feet wide by 53 feet long),
along with 39 passenger vehicle parking spaces, including accessible parking, for on-site personnel. A 1,558-
square-foot prefabricated office building would be located in the southeast corner of the Project Site, adjacent to
Almond Avenue, providing office and restroom facilities to support site operations. A small pre-fabricated guard
shack, approximately 160 square feet, would be positioned adjacent to the entry driveway to facilitate site access
control. The Project would also include a trash/recycling enclosure and landscaped areas along the Site’s
perimeter and internal drive aisles (described in further detail on the following page). Vehicular access to the
Project would be provided via a single full-access driveway connection to Almond Avenue, located at the southeast
corner of the Project Site.
A 14-foot-tall concrete tilt-up wall would be constructed along the perimeter of the Project Site. The wall would
screen trailers and on-site operations from the public right-of-way and adjacent properties, including viewpoints
along Almond Avenue. Security lighting would be installed throughout the facility.
B. Conceptual Architecture Plan
The proposed office building would be a single-story prefabricated structure, approximately 18 feet in height. The
building would provide approximately 1,558 square feet of floor area and include administrative office space and
restroom facilities to support on-site operations. The building would feature a one-story design, smooth wall
panels with brick-pattern accent veneer, a glazed entry element, and metal canopy accents, painted in a palette
of white and medium- to dark-gray tones consistent with surrounding industrial uses. The proposed architectural
Addendum to the
SWIP Specific Plan Update and Annexation PEIR Project Description
Almond Avenue Trailer Yard 3-2
elevations are illustrated on Figure 3-2, Conceptual Architectural Elevations, and the proposed materials are
illustrated on Figure 3-3, Conceptual Material Board.
C. Conceptual Landscape Plan
The Project Site currently contains limited existing vegetation, consisting primarily of trees and grass along
portions of the Site perimeter, while the interior of the Site is largely disturbed and devoid of vegetation. Existing
vegetation within the Project Site would be removed during Project construction. Proposed landscaping would
include a mixture of ornamental and drought-tolerant plant species, featuring low- and moderate-water-use trees,
shrubs, accent plantings, and low-growing groundcover to provide visual interest and soften the Site’s perimeter.
As shown on Figure 3-4, Conceptual Landscape Plan, landscaping would be installed primarily along the eastern,
southern, and western edges of the Project Site, including within a landscaped berm installed along the Project
Site’s frontage on Almond Avenue. To maintain clear and efficient circulation for trailers, the interior truck court
would remain free of landscaping, with plant materials limited to perimeter areas where they would not interfere
with on-site operations. Prior to building permit issuance, the Project Applicant would be required to submit final
planting and irrigation plans to the City of Fontana for review and approval. The plans are required to comply with
the “Landscape and Water Conservation Ordinance” from Chapter 28, Article IV, Section 28-91 through 28-119 of
the Fontana Municipal Code, which establishes requirements for landscape design, automatic irrigation system
design, and water-use efficiency.
3.1.2 Conditional Use Permit
The proposed Conditional Use Permit (CUP No. 25-0015, ) is required to authorize operation of the proposed
trailer parking facility, as specified by the zoning requirements for the Speedway Industrial District (SID) of the
Southwest Industrial Park (SWIP) Specific Plan. The CUP process allows the City to evaluate conditions relative to
the development impacts, considering factors such as truck circulation, screening, and compatibility with
surrounding industrial development.
3.2 Project Technical Characteristics
3.2.1 Public Road Improvements
The Project Site abuts one public street: Almond Avenue to the east. As part of the Project, frontage improvements
would be made to Almond Avenue as follows:
Almond Avenue
The Project would construct frontage and access improvements along the west side of Almond Avenue consistent
with City of Fontana requirements. Because no formal driveway connection to the Project Site currently exists,
the Project would install a new driveway approach in conformance with City Standard No. 1018. The Project would
also complete any frontage repairs such as curb, gutter, or sidewalk replacement as identified during final
engineering review, along with any necessary ADA transitions, utility adjustments in the public right-of-way, and
minor signage or striping modifications. In addition, new streetlights would be installed along the Project frontage
on the Almond Avenue in conformance with City Standard No. 1017. No roadway widening or intersection
improvements would be needed. All improvements would occur within existing developed public right-of-way.

SWIP Specific Plan Update and Annexation PEIR Project Description
Almond Avenue Trailer Yard 3-3
3.2.2 Utility Improvements
The Project’s proposed utility plan is depicted on Figure 3-5, Conceptual Utility Plan and described below.
Water Infrastructure
Water service to the Project Site would be provided by the Fontana Water Company (FWC). As shown on the
Conceptual Utility Plan, the Project would include a new water service connection from Almond Avenue to serve
domestic and irrigation demands associated with the office building and perimeter landscaping. All proposed
water facilities would be designed and constructed in accordance with FWC standards and City of Fontana
requirements. The Project also includes installation of a new public fire hydrant along Almond Avenue to provide
fire protection service in compliance with City of Fontana Fire Department and FWC requirements. Final sizing,
spacing, and configuration of fire protection infrastructure would be confirmed during final engineering and
building permit review.
Overall water demand associated with the Project would be relatively low due to the limited building area and
absence of water-intensive uses. The Project would not require expansion of off-site water supply infrastructure
and would be adequately served by existing municipal water facilities.
Sanitary Sewer Infrastructure
Wastewater service for the Project Site would be provided by the City of Fontana. Under proposed conditions,
wastewater generation would be limited to domestic flows associated with restroom facilities within the on-site
office building. No industrial wastewater, process discharges, truck washing, or other water-intensive activities
are proposed as part of the Project. As shown on the Conceptual Utility Plan, the Project would include a new 6-
inch VCP sanitary lateral serving the office building, which would connect to the existing 8-inch municipal sewer
main in Almond Avenue. All sewer facilities would be designed and constructed in accordance with City of Fontana
standards and requirements. The Project would not require expansion of off-site sewer conveyance or wastewater
treatment facilities and would be adequately served by existing municipal infrastructure.
Stormwater Drainage Infrastructure
The Project would include construction of an on-site stormwater drainage system designed to collect, treat, and
convey stormwater runoff in accordance with the City of Fontana storm drain standards, the Project’s Water
Quality Management Plan (WQMP), and applicable Municipal Separate Storm Sewer System (MS4) requirements.
The storm drain system would consist of on-site catch basins, private storm drain piping, and water quality
treatment features designed to manage runoff generated by the proposed improvements. Stormwater runoff
generated during storm events would be collected by the on-site drainage facilities and directed to water quality
treatment measures designed to capture and treat the initial runoff (“first flush”), which typically contains the
highest concentration of pollutants. Treatment measures would include low impact development (LID)-based best
management practices (BMPs), such as infiltration and filtration features, as identified in the approved WQMP.
Treated stormwater would be managed on site to the maximum extent practicable, with controlled discharge to
the existing public storm drain system, as required.
The Project would not require construction of new off-site storm drain facilities or expansion of existing
downstream infrastructure. Final storm drain design details, including the location and configuration of storm
Addendum to the
SWIP Specific Plan Update and Annexation PEIR Project Description
Almond Avenue Trailer Yard 3-4
drain facilities and water quality BMPs, would be reviewed and approved by the City of Fontana during final
engineering and permitting.
Dry Utilities
Electric power and natural gas services are available to the Project Site and surrounding area. Utility purveyors
serving the Project vicinity include Southern California Edison (SCE) for electric service and Southern California
Gas Company (SoCalGas) for natural gas service. Telecommunications and fiber optic services are provided by
various private providers including AT&T and Charter Communications. Existing overhead electrical facilities,
consisting of power poles and overhead lines, are located along the east side of Almond Avenue adjacent to the
Project frontage. As part of the Project, the existing power poles would be removed and the overhead electrical
lines would be undergrounded. Underground utility improvements would be designed and constructed in
accordance with applicable utility purveyor standards and City requirements. Final utility routing, connection
locations, and appurtenances (e.g., pull boxes, vaults, cabinets, and pad-mounted equipment) would be
determined during final engineering in coordination with SCE and the City Engineering Department.
3.3 Construction Characteristics
Project construction is anticipated to span a period of approximately 12 months. The expected duration of each
stage of construction is summarized in Table 3-1, Construction Schedule. The composition of the construction
equipment fleet that the Project Applicant intends to use to construct the Project is summarized in Table 3-2,
Construction Equipment Fleet. Project construction activities and equipment would be required to comply with
the applicable sustainability standards established by Fontana Municipal Code Chapter 30, Article VII Industrial
Zoning Districts.

The Project’s proposed grading activities would affect the entire Project Site. Other than the roadway and utility
improvements described above, no other off-site physical impacts are anticipated as part of the Project.
Before grading begins, the Project Site would be prepared by reworking the existing gravel surface, removing
materials and equipment stockpiles, and clearing any remaining debris associated with the existing use. Earthwork
activities associated with Project construction would result in approximately 16,957 cubic yards (cy) of cut and
16,957 cubic yards of fill, respectively, with no import or export of soil required. When grading is complete, the

Project Site would create a level surface suitable for paving and trailer storage. Minor elevation changes would
occur to establish proper stormwater drainage but, overall, the Project Site would be perceived as flat. The Project
grading concept is illustrated on Figure 3-8, Proposed Grading Plan.

3.4 Operational Characteristics
The Project would operate as an outdoor trailer storage facility with a small onsite office building for
administrative activities and a separate guard station located near the primary site entrance for access control.
No warehousing, distribution, or indoor material-handling activities are proposed as part of the Project and would
not contain any building in which cargo, goods, or products are moved or stored for later distribution to business
or retail customers. The Project Site would be used exclusively for the parking and storage of empty or loaded
truck trailers, with tractor units entering the Site only for trailer pick-up and drop-off. No outdoor storage of
materials unrelated to trailer parking would occur.
The specific end user of the Project has not yet been identified; however, operations would be limited to trailer
storage and routine management activities typically associated with this type of facility. Hazardous materials
storage is not proposed. Small quantities of maintenance-related products (such as cleaners or lubricants) may be
stored in limited amounts consistent with normal business operations. No fueling station, repair facility, or truck-
washing operations are proposed. For purposes of this Addendum, Project operations were analyzed
Addendum to the
SWIP Specific Plan Update and Annexation PEIR Project Description

conservatively, assuming activities could occur 24 hours per day, seven days per week, with onsite lighting used
during nighttime hours. All exterior lighting would comply with Fontana Municipal Code Section 30-544, which
requires lighting to be directed and/or shielded to prevent adverse effects on adjacent properties and prohibits
lighting that creates adverse glare..
Employee and visitor trips would be minimal, as operations primarily consist of trailer drop-offs and pick-ups.
Using the trip generation rates given in the Institute of Transportation Engineers (ITE) Trip Generation Manual
(12th Edition) and based on calculations from the Project’s transportation assessment (Appendix L), the Project is
anticipated to generate approximately 238 total vehicle trips per day, including 15 trips during the morning peak
hour and 18 during the evening peak hour. Water demand would be limited to the office building and landscape
irrigation, and wastewater generation would similarly be minimal and limited to office-related uses.

4.0 ENVIRONMENTAL ANALYSIS
Addendum to the
SWIP Specific Plan Update and Annexation PEIR Environmental Analysis
Almond Avenue Trailer Yard 4-1
4.0 ENVIRONMENTAL ANALYSIS
The scope of the City’s environmental review of the Project is governed by CEQA (See Public Resources Code
Section 21166) and the CEQA Guidelines (See CEQA Guidelines Section 15162). The environmental review
evaluates the environmental effects associated with implementation of the Project and compares this with the
information and environmental effects that were expected from buildout of the SWIP SP and as disclosed in the
SWIP SP PEIR. This Addendum also reviews new information, if any, of substantial importance that was not known
and could not have been known with the exercise of reasonable due diligence at the time the SWIP SP PEIR was
certified. This evaluation includes a determination as to whether the Project would result in any new significant
impacts or a substantial increase to a previously identified significant impact.
Because the CEQA Guidelines do not stipulate the format or content of an Addendum, the topical areas identified
in the City of Fontana’s Initial Study form (as set forth in the City’s 2019 Local Guidelines for Implementing the
California Environmental Quality Act, adopted April 23, 2019) were used as guidance for this Addendum. This
analysis provides the City with the factual basis for determining whether any changes in the Project, any changes
in circumstances, or any new information that has become available since the certification of the SWIP SP PEIR
would require additional environmental review (i.e., preparation of a Subsequent or Supplemental EIR).
A Mitigation Monitoring and Reporting Program (MMRP) was adopted in conjunction with certification of the
SWIP SP PEIR. The MMRP specified MMs that would apply to development activities within the SWIP SP area to
minimize the environmental effects of the SWIP SP implementation. The previously adopted MMs applicable to
the Project will be imposed as conditions of approval and are listed in Appendix A, attached hereto.
On the basis of this evaluation:
I find that the significant effects that would result from the Project have been addressed in an earlier certified EIR
(Southwest Industrial Park Specific Plan Update and Annexation Program EIR, State Clearinghouse Number
2009091089) and that none of the determinations set forth in the Public Resources Code Section 21166 and State
CEQA Guidelines Section 15162 can be established and, thus, an Addendum to the Southwest Industrial Park
Specific Plan Update and Annexation Program EIR shall be prepared.

Almond Avenue Trailer Yard 4-2
4.1 Aesthetics
Would the Project:
a. Have a substantial adverse effect on a scenic vista?
SWIP SP PEIR Finding: The SWIP SP PEIR identified scenic vistas adjacent to the southeastern portion of the SWIP
SP area in the form of uninterrupted, panoramic views of the San Gabriel/San Bernardino Mountains to the north
and Jurupa Mountains to the south, as well as scenic vistas in the form of isolated windrows viewed across large
open spaces and along several roadways within the southern portion of the SWIP SP. The SWIP SP PEIR concluded
that although the SWIP SP includes various design features to minimize impacts to scenic vistas and would comply
with existing local requirements related to scenic vistas, implementation of the SWIP SP would result in significant
and unavoidable direct and cumulatively considerable impacts to scenic vistas and there were no feasible MMs
that would reduce the impacts to a level below significance. The City adopted a Statement of Overriding
Considerations for this impact in conjunction with certification of the SWIP SP EIR.
Analysis of Project: The Project Site is in the northern portion of the SWIP SP area, which is not an area identified
within the SWIP SP PEIR as having scenic vistas. The Project Site is located along Almond Avenue, within a fully
developed and urbanized portion of the City characterized by industrial uses and truck-related facilities. The
Project Site does not contain or adjoin any designated scenic resources or open space areas that contribute to a
public scenic vista. Existing views of distant mountain ranges are intermittently visible along Almond Avenue but
are already obstructed by existing industrial development, structures, and utility infrastructure. The most visually
prominent components of proposed trailer parking facility, the prefabricated office building and guard shack, and
perimeter walls/fencing, would not be tall enough to substantially alter the visual character of the area or obstruct
remaining distant mountain views. Because the Project is consistent with the industrial land use designation and
development intensity evaluated in the certified SWIP PEIR, and the Project Site does not contribute to any
identified scenic vista, implementation of the Project would not result in any new or more severe scenic vista
impacts than the significant and unavoidable direct and cumulatively considerable impacts previously disclosed in
the SWIP SP PEIR.
b. Substantially damage scenic resources, including, but not limited to, trees, rock outcroppings, and historic
buildings within a state scenic highway?
SWIP SP PEIR Finding: The SWIP SP PEIR determined that the SWIP SP area does not contain any geologic
formations or historic structures that could be characterized as scenic resources. Further, the SWIP SP PEIR
concludes that compliance with Article III - Preservation of Heritage, Significant and Specimen Trees of the City of
Fontana Municipal Code would minimize impacts to mature trees within the SWIP SP. The SWIP SP PEIR concluded
that impacts to scenic resources would be less than significant.
Analysis of Project: According to the California Department of Transportation (CalTrans), there are no State-
designated scenic highways in the vicinity of the Project Site (CalTrans, 2025). Furthermore, the Project Site does
not contain any scenic resources, including, but not limited to, trees, rock outcroppings, and historic buildings.
Accordingly, the Project would have no impact on any scenic resources, including scenic resources within a state
Addendum to the
SWIP Specific Plan Update and Annexation PEIR Environmental Analysis
Almond Avenue Trailer Yard 4-3
scenic highway corridor. Implementation of the Project would not result in any new or more severe significant
impacts to scenic resources within a State scenic highway than previously disclosed in the SWIP SP PEIR.
c. In non-urbanized areas, substantially degrade the existing visual character or quality of public views of the
site and its surroundings? (Public Views are those that are experienced from publicly accessible vantage
points). If the project is an urbanized area, would the project conflict with applicable zoning and other
regulations governing scenic quality?
SWIP SP PEIR Finding: The SWIP SP PEIR determined that construction activities within the SWIP SP area that
occur near residentially-zoned property would result in temporary significant impacts to the visual
quality/character of the SWIP SP area. However, the SWIP SP PEIR included a MM (MM 4.1-3a) that would require
development projects located within or near residentially-zoned property to incorporate practices during
construction to minimize visual impact. With application of the identified mitigation, the SWIP SP PEIR concluded
that impacts to visual quality/character during construction would be less than significant. The SWIP SP PEIR
concluded that long-term impacts to visual quality/character would be less than significant with mandatory
adherence to the land use and development regulations established in the SWIP SP.
Analysis of Project: Because the Project Site is neither zoned for residential land uses nor abuts residentially zoned
properties, SWIP PEIR Mitigation Measure 4.1-3a is not applicable to the Project and the Project would not be
required to implement any special construction practices to address adverse aesthetic impacts. The proposed
trailer parking facility would redevelop an outdoor storage yard with minimal screening and no landscaping with
a modern trailer parking facility that is fully screened from the public right-of-way by a 14-foot-tall solid screen
wall. The Project includes a landscape plan that would consist of ornamental trees, shrubs, and groundcovers
selected to soften the visual appearance of perimeter improvements and enhance the overall aesthetic quality of
the Site relative to existing conditions. Additionally, landscaping will be planted on a berm along the Project Site’s
frontage along Almond Avenue to minimize the perceived height of the screen wall. The City conducted a thorough
review of the Project’s design and determined that the Project would be consistent with the applicable
development standards and design guidelines from the SWIP SP. Accordingly, there are no components of the
Project that would degrade the existing visual character or quality of the Site and its surroundings beyond what
was evaluated and disclosed in the SWIP PEIR. Implementation of the Project would not result in any new or more
severe significant impacts to visual character or quality than previously disclosed in the SWIP PEIR.
d. Create a new source of substantial light or glare, which would adversely affect day or nighttime views in
the area?
SWIP SP PEIR Finding: The SWIP SP PEIR disclosed that implementation of the SWIP SP would have the potential
to create new sources of outdoor light and glare in the form of streetlights, exterior lighting, and security lighting,
as well as glare effects caused by reflective surfaces. However, the SWIP SP PEIR determined that light and glare
impacts would be less than significant because development within the SWIP SP area would be required to comply
with the lighting requirements of the Fontana Municipal Code Chapter 30 which would minimize the potential for
light and/or glare effects to occur. Accordingly, the SWIP SP PEIR concluded that light and/or glare impacts from
implementation of the SWIP SP would be less than significant.
Addendum to the
SWIP Specific Plan Update and Annexation PEIR Environmental Analysis
Almond Avenue Trailer Yard 4-4
Analysis of Project: The Project would be required to comply with the SWIP SP design guidelines applicable to
outdoor lighting. In addition, the Project would be required to comply with the outdoor lighting standards
contained in the Fontana Municipal Code Chapter 30. The Municipal Code lighting standards govern the placement
and design of outdoor lighting fixtures to ensure adequate lighting for public safety while also minimizing light
pollution and glare and precluding public nuisances (e.g., blinking/flashing lights, unusually high intensity, or bright
lighting). Through mandatory compliance with these standards, Project implementation would result in a less-
than-significant impact related to lighting and glare by: 1) ensuring that the Project would be compatible with the
setting of the surrounding area; 2) preventing substantial light or glare from falling on public streets or property
adjoining the Project Site; and 3) preventing “spillover” effects from the Project Site that could interfere with day
or nighttime views in the area. Implementation of the Project would not result in any new or more severe
significant impacts related to lighting/glare than previously disclosed in the SWIP SP PEIR.
4.2 Agriculture and Forestry Resources
Would the project:
a. Convert Prime Farmland, Unique Farmland, or Farmland of Statewide Importance (Farmland), as shown
on the maps prepared pursuant to the Farmland Mapping and Monitoring Program of the California
Resources Agency, to non-agricultural use?
SWIP SP PEIR Finding: The SWIP SP PEIR disclosed that implementation of the SWIP SP would not convert any
“Prime Farmland,” “Unique Farmland,” or “Farmland of Statewide Importance” to non-agricultural use, as there
is no prime farmland, unique farmland, or farmland of statewide importance located within the SWIP SP
boundaries. The SWIP SP PEIR concluded that no impact would occur.
Analysis of Project: The Project Site is mapped by the California Department of Conservation (DOC) as “Urban and
Built-Up Land” (DOC, 2022). Implementation of the Project would, therefore, not result in the conversion of Prime
Farmland, Unique Farmland, or Farmland of Statewide Importance to non-agricultural use. No impact would
occur. Implementation of the Project would not result in any new or more severe significant impacts to agricultural
resources than previously disclosed in the SWIP SP PEIR.
b. Conflict with existing zoning for agricultural use, or a Williamson Act contract?
SWIP SP PEIR Finding: The SWIP SP PEIR disclosed that none of the lands within the SWIP SP area were designated
or zoned for agricultural use, or subject to a Williamson Act contract. Therefore, the SWIP SP PEIR concluded that
no impacts would occur.
Analysis of Project: The Project Site is neither zoned for agricultural use nor subject to a Williamson Act contract.
Accordingly, the Project would not conflict with existing zoning for agricultural use or with a Williamson Act
contract. Implementation of the Project would not result in any new or more severe significant impacts to
agricultural resources than previously disclosed in the SWIP SP PEIR.
Addendum to the
SWIP Specific Plan Update and Annexation PEIR Environmental Analysis
Almond Avenue Trailer Yard 4-5
c. Conflict with existing zoning for, or cause rezoning of, forest land (as defined in Public Resources Code
section 12220(g)), timberland (as defined by Public Resources Code section 4526), or timberland zoned
Timberland Production (as defined by Government Code section 51104(g))?
SWIP SP PEIR Finding: The SWIP SP PEIR disclosed that there are no areas zoned for forest land, timberland, or
Timberland Production exist within the vicinity of the SWIP SP.
Analysis of Project: The Project Site is not zoned for forest land or timberland. Additionally, there are no lands in
the Project Site vicinity that are zoned for forest land or timberland. Therefore, implementation of the Project
would not conflict with, or cause the rezoning of, forest land or timberland. Implementation of the Project would
not result in any new or more severe significant impacts to forestry resources than previously disclosed in the
SWIP SP PEIR.
d. Result in the loss of forest land or conversion of forest land to non-forest use?
SWIP SP PEIR Finding: The SWIP SP PEIR disclosed that the SWIP SP exists within an urbanized area, occupied
primarily by industrial uses, and that no forest land exists within the site vicinity.
Analysis of Project: The Project Site is not zoned for forest land nor does any forest land exist in the vicinity of the
SWIP SP. The Project Site, and the surrounding area, is highly urbanized and is used primarily for industrial
purposes (Google Earth Pro, 2025). Therefore, the Project would not result in the loss of forest land, nor will any
forest land be converted to non-forest land. Implementation of the Project would not result in any new or more
severe significant impacts to forestry resources than previously disclosed in the SWIP SP PEIR.
e. Involve other changes in the existing environment which, due to their location or nature, could result in
conversion of Farmland, to non-agricultural use or conversion of forest land to non-forest use?
SWIP SP PEIR Finding: The SWIP SP PEIR disclosed that there are no active agricultural areas or forest land areas
within the SWIP SP area. Accordingly, the SWIP SP PEIR concluded that no impacts would occur.
Analysis of Project: As previously discussed above, the Project Site does not include Farmland (defined as Prime
Farmland, Unique Farmland, or Farmland of Statewide Importance) or forest land and, therefore, would not
convert Farmland to non-agricultural use of forest land to non-forest use. The Project would not result in any
impacts to agricultural and/or forestry resources. Implementation of the Project would not result in any new or
more severe significant impacts to agricultural/forestry resources than previously disclosed in the SWIP SP PEIR.
4.3 Air Quality
An Air Quality Assessment, dated February 16, 2026 (Urban Crossroads, 2026a), and Mobile Source Health Risk
Assessment, dated February 16, 2026 (Urban Crossroads, 2026b), were prepared for the Project by Urban
Crossroads, Inc. (Urban Crossroads) to evaluate potential criteria and hazardous air pollutant emissions that could
result from the Project’s construction and operation. These reports are included as Appendices B and C,
respectively, to this EIR Addendum and their findings are incorporated into the analysis presented herein.
Addendum to the
SWIP Specific Plan Update and Annexation PEIR Environmental Analysis
Almond Avenue Trailer Yard 4-6
Would the project:
a. Conflict with or obstruct implementation of the applicable air quality plan?
SWIP SP PEIR Finding: The SWIP SP PEIR disclosed that emissions resulting from buildout of the SWIP SP would
exceed SCAQMD thresholds and would potentially result in a long-term impact on the region’s ability to meet
State and Federal Ambient Air Quality Standards. Therefore, the SWIP SP PEIR concluded that buildout of the SWIP
SP would conflict with the 2007 Air Quality Management Plan (AQMP) for the South Coast Air Basin (2007 AQMP).
The SWIP SP PEIR included mitigation to minimize the SWIP SP’s air pollutant emissions; however, the SWIP SP
PEIR concluded that air quality impacts related to a conflict with or obstruction of the implementation of the 2007
AQMP would be significant and unavoidable. The City of Fontana adopted a Statement of Overriding
Considerations for this impact in conjunction with certification of the SWIP SP EIR.
Analysis of Project: The Project Site is located within the South Coast Air Basin (SCAB or “Basin”). The SCAQMD is
principally responsible for air pollution control in the SCAB. The SCAQMD has adopted a series of AQMPs to reduce
air emissions in the Basin. When the SWIP SP PEIR was certified, the SCAQMD’s 2007 AQMP was the applicable
air quality plan for the SCAB. Since that time, the SCAQMD has adopted the 2022 AQMP which was approved in
December 2022 and is in effect at this time. For purposes of evaluation and to determine whether the Project
would result in any new or more severe significant air quality impacts than disclosed in the SWIP SP PEIR,
consistency with both the 2007 AQMP, which was applicable at the time the SWIP SP PEIR was written, and the
2022 AQMP are discussed below.
The SWIP SP PEIR concluded that buildout of the SWIP SP would conflict with the 2007 AQMP due to the resulting
operational emissions that would impede the region’s ability to meet State and Federal Ambient Air Quality
Standards. The Project would implement the SWIP SP land use plan but would, in fact, generate substantially
fewer net daily traffic trips than the land uses assumed by the SWIP SP PEIR (the Project’s daily traffic is discussed
in further detail in EIR Addendum Subsection 4.17). Thus, the Project would reduce vehicle tailpipe emissions
within the SWIP SP area relative to the levels disclosed in the SWIP SP PEIR, although the emissions reductions
provided by the Project would not be sufficient to avoid the significant and unavoidable conflict with the 2007
AQMP that was disclosed in the SWIP EIR. Further, the Project will be required to comply with much stricter air
quality regulations than those that existed in 2012 (when the SWIP SP PEIR was certified), including regulations
applicable to truck and other vehicle emissions that are much more protective of the environment and that will
reduce emissions when compared to the emissions that the SWIP SP PEIR assumed would occur from build out of
the SWIP SP area (including development of the Project Site). Implementation of the Project would contribute to
the significant and unavoidable conflict with the 2007 AQMP that was identified in the SWIP SP PEIR; but, would
neither result or contribute to a new, significant conflict with the 2007 AQMP nor increase the severity of the
conflict previously disclosed in the SWIP SP PEIR and, instead, would result in less severe air quality impacts.
The Project is consistent with the SWIP SP, which was approved by the City in 2012, is reflected on the City of
Fontana’s General Plan Land Use Map, and is accounted for by the growth projections utilized by SCAQMD during
preparation of the 2022 AQMP. Thus, the Project would be consistent with the 2022 AQMP, which relies on
adopted local General Plans for growth (and emissions) projections. Furthermore, the Project would not increase
the severity of existing air quality violations; cause or contribute to new violations; or delay the timely attainment
of the air quality standards established in the 2022 AQMP (as discussed under Responses 4.3(b) and (c), below).
Addendum to the
SWIP Specific Plan Update and Annexation PEIR Environmental Analysis
Almond Avenue Trailer Yard 4-7
Based on the foregoing analysis, the Project would not conflict with or obstruct implementation of the 2007 or
2022 AQMP. Implementation of the Project would not result in any new or more severe significant impacts to
related to air quality than the significant and unavoidable impacts previously disclosed in the SWIP SP PEIR.
b. Result in a cumulatively considerable net increase of any criteria pollutant for which the project region is
non-attainment under an applicable federal or state ambient air quality standard?
SWIP SP PEIR Finding: The SWIP SP PEIR determined that implementation of the SWIP SP would result in
cumulatively considerable net increases of criteria pollutants, including ozone precursors, for which the SCAB is
in non-attainment of applicable federal and/or state ambient air quality standards. The SWIP SP PEIR included
mitigation to minimize the SWIP SP’s air pollutant emissions; however, the SWIP SP PEIR concluded that
cumulative air quality impacts would be significant and unavoidable. The City of Fontana adopted a Statement of
Overriding Considerations for this impact in conjunction with certification of the SWIP SP EIR.
Analysis of Project: The Project Applicant would redevelop the Project Site with land uses permitted by the SWIP
SP; therefore, the Project would not generate air pollutant emissions that were not already anticipated by the
SWIP SP PEIR. Further, as stated above, regulations enacted since 2012 would generally reduce the Project’s
emissions when compared to the emissions assumed in the SWIP SP PEIR.
Notwithstanding, an Air Quality Impact Analysis (AQIA, Appendix B to this EIR Addendum) was prepared to
quantify air pollutant emissions associated with the implementation of the Project. The Project’s maximum
construction-related criteria pollutant emissions and operational criteria pollutant emissions are summarized in
Table 4-1, Project Construction Emissions Summary and Table 4-2, Project Operational Emissions Summary,
respectively. The methodology used to calculate the air pollutant emissions associated with the Project is
described in detail in the AQIA. It should be noted that although the Project would be required to comply with all
applicable MMs from the SWIP SP PEIR that were required to reduce air pollution, the analysis below does not
take credit for any emission reductions that would result from the implementation of the SWIP SP PEIR MMs.
Thus, the actual construction and operational emissions associated with the Project is expected to be less than
the quantities disclosed in Table 4-1 and Table 4-2.

As shown in Table 4-1 and Table 4-2, Project-related construction and operational activities would not exceed the
SCAQMD significance threshold for any criterial pollutant. The SCAQMD considers any project-specific criteria
pollutant emissions that exceed applicable SCAQMD significance thresholds also to be cumulatively considerable.
Conversely, if a project does not exceed the SCAQMD regional thresholds, then SCAQMD considers that project’s
air pollutant emissions to not be cumulatively considerable because criteria pollutant emissions that fall below
the significance threshold would not adversely affect SCAQMD’s ability to meet air quality standards within the
SCAB. Thus, because Project construction and operation would not exceed the SCAQMD significance thresholds,
implementation of the Project would not result in a cumulatively considerable net increase of any criteria
pollutant, including any pollutants for which the SCAB does not attain applicable federal or State ambient air
quality standards. Furthermore, it bears noting that the Project operations would generate substantially fewer
net daily traffic trips than the land uses assumed by the SWIP SP PEIR (the Project’s daily traffic is discussed in
further detail in EIR Addendum Subsection 4.17). Thus, the Project would reduce vehicle tailpipe emissions within
the SWIP SP area relative to the levels disclosed in the SWIP SP PEIR, although the emissions reductions provided
by the Project would not be sufficient to avoid the significant and unavoidable cumulative impact that was
disclosed in the SWIP EIR. Implementation of the Project would not result in any new or more severe significant
impacts to related to air quality than the significant and unavoidable direct and cumulative considerable impacts
previously disclosed in the SWIP SP PEIR.
Mitigation: Although the Project would not contribute cumulatively considerable volumes of criteria pollutant
emissions, the Project would be required to comply with applicable MMs identified in the SWIP SP PEIR to reduce
cumulative air pollutant emissions across the SWIP SP area, as presented below in the Mitigation Monitoring and
Reporting Program (MMRP) for the SWIP SP PEIR (attached hereto as Appendix A).

• Discontinue operation during second-stage smog alerts.
• All haul trucks shall be covered prior to leaving the site to prevent dust from impacting
the surrounding areas.
• Comply with AQMD Rule 403, particularly to minimize fugitive dust and noise to
surrounding areas.
• Moisten soil each day prior to commencing grading to depth of soil cut.
• Water exposed surfaces at least twice a day under calm conditions, and as often as
needed on windy days or during very dry weather in order to maintain a surface crust and
minimize the release of visible emissions from the construction site.
• Treat any area that will be exposed for extended periods with a soil conditioner to
stabilize soil or temporarily plant with vegetation.
• Wash mud-covered tires and under carriages of trucks leaving construction sites.
• Provide for street sweeping, as needed, on adjacent roadways to remove dirt dropped by
construction vehicles or mud, which would otherwise be carried off by trucks departing
Project Sites.
• Securely cover all loads of fill coming to the site with a tight-fitting tarp.
• Cease grading during periods when winds exceed 25 miles per hour.
• Provide for permanent sealing of all graded areas, as applicable, at the earliest practicable

MM 4.2-2c All industrial and commercial facilities shall post signs requiring that trucks shall not be left idling
for prolonged periods pursuant to Title 13 of the California Code of Regulations, Section 2485,
which limits idle times to not more than five minutes.
MM 4.2-2j All residential, commercial, and industrial structures shall be required to incorporate light colored
roofing materials.
Note: The following SWIP SP PEIR MMs do not apply to the Project or have been satisfied as part of the City’s
review of the Project’s proposed entitlement applications: Mitigation Measure MM 4.2-1d does not apply because
the Project does not include residential development and does not include 45,000 square feet or more of retail,
commercial, or industrial building space that would trigger the applicability thresholds of the measure. MMs 4.2-
2a and 4.2-2b do not apply to the Project based on the location of the Project Site within the SWIP SP area; MMs
4.2-2d, MM 4.2-2e, MM 4.2-2f, and MM 4.2-2g do not apply because the Project consists of a trailer storage yard
with a small accessory office building and would not generate the level or type of on-site employment associated
with these measures (e.g., preferential vanpool parking, food service uses, or transit schedule posting and
coordination requirements for tenants with 50 or more employees). MMs 4.2-2h and 4.2-2i do not apply to the
Project because these MMs only apply to residential and commercial buildings; and MMs 4.2-2k and 4.2-2l were
satisfied by the Air Quality Impact Analysis (Appendix B) and Mobile Source Health Risk Assessment (Appendix C)
prepared for the Project.
c. Expose sensitive receptors to substantial pollutant concentrations?
SWIP SP PEIR Finding: The SWIP SP PEIR determined that construction and operation of the SWIP SP would not
expose any sensitive receptors to substantial, localized pollutant concentrations. The SWIP SP PEIR concluded that
air quality impacts related to localized pollutant concentrations would be less than significant and no mitigation
was required.
Analysis of Project: The Project would redevelop the Project Site with land uses permitted by the SWIP SP;
therefore, the types of air pollutant emissions generated by the Project already were anticipated by the SWIP SP
PEIR. Further, as noted previously, the Project is anticipated to substantially reduce vehicle traffic to and from the
Project Site below the levels assumed by the SWIP SP PEIR and regulations enacted since the SWIP SP PEIR was
certified in 2012, both of which would generally reduce the Project’s emissions when compared to the emissions
disclosed in the SWIP SP PEIR. Notwithstanding, an AQIA and HRA were performed to quantify localized air
pollutant emissions associated with construction and operation of the Project. The methodologies used to
calculate the localized criteria air pollutant emissions associated with the Project is described in detail in the AQIA
and HRA (see Appendices B and C, respectively).
Project-related construction localized emissions are presented in Table 4-3, Project Construction Localized
Emissions Summary. The data presented in Table 4-3 confirms the Project would not exceed the SCAQMD
significance thresholds for localized air pollutant emissions during construction. Therefore, Project construction
would expose sensitive receptors near the Project Site to less-than-significant localized criteria pollutant
concentrations.

Additionally, a mobile source health risk analysis was prepared to evaluate the potential for the proposed use and
design for the Project to expose residential, worker, and school child receptors near the Project Site to localized
diesel emissions that could result in carcinogenic and non-carcinogenic health effects. The methodology used to
calculate Project-related localized diesel emissions is described in detail in Appendix C. The results of the mobile
source health risk analysis are summarized in Table 4-5, Summary of Construction Health Risks and Table 4-6,
Summary of Project-Related Diesel Emissions Health Risks which show that the Project’s construction and
operation would result in less-than-significant health risks (carcinogenic and non-carcinogenic) to sensitive
receptors in the Project vicinity.

Lastly, the Air Quality Impact Analysis concluded that the Project would not produce the volume of traffic
required to cause or contribute to the formation of a CO “hot spot” (Urban Crossroads, 2026a, p. 23)
Addendum to the
SWIP Specific Plan Update and Annexation PEIR Environmental Analysis
Almond Avenue Trailer Yard 4-14
Based on the foregoing analysis, the Project would not expose sensitive receptors near the Project Site to
significant pollutant concentrations during construction and operation. Implementation of the Project would not
result in any new or more severe significant impacts to related to air quality than previously disclosed in the SWIP
SP PEIR.
d. Result in other emissions (such as those leading to odors) adversely affecting substantial number of
people?
SWIP SP PEIR Finding: The SWIP SP PEIR concluded that implementation of the SWIP SP would not expose a
substantial number of people to objectionable odors.
Analysis of Project: Project construction activities could produce odors resulting from construction equipment
exhaust, application of asphalt, and/or the application of architectural coatings; however, standard construction
practices would minimize the odor emissions and their associated impacts. Furthermore, any odors emitted during
construction would be temporary, short-term, and intermittent in nature, and would cease upon the completion
of the respective phase of construction. In addition, construction activities on the Project Site would be required
to comply with SCAQMD Rule 402, which prohibits the discharge of odorous emissions that would create a public
nuisance (SCAQMD, 2005a). Accordingly, the Project would not create objectionable odors affecting a substantial
number of people during construction.
During long-term operation, the proposed Project would include trailer storage land uses, which are not typically
associated with objectionable odors. Project operations would not generate substantial solid waste. Refuse would
be limited to minor waste from the on-site office and routine property maintenance. A trash/recycling enclosure
is included on-site and would be removed at regular intervals in compliance with the City’s solid waste regulations.
Furthermore, the proposed Project would be required to comply with Fontana Municipal Code Section 30-261,
Odors, and SCAQMD Rule 402, which prohibits the discharge of odorous emissions that would create a public
nuisance, during long-term operation. As such, long-term operation of the proposed Project would not create
objectionable odors affecting a substantial number of people.
The Project would not create objectionable odors affecting a substantial number of people during either
construction or long-term operation; impacts would be less than significant. Implementation of the Project would
not result in any new or more severe significant impacts related to objectional odors than previously disclosed in
the SWIP SP PEIR.
4.4 Biological Resources
A Biological Resources Report (dated November 2025) (Cadre, 2025) was prepared for the Project by Cadre
Environmental (Cadre). The Biological Resources Report evaluates the existing biological resources on the Project
Site and evaluates the potential impacts to these resources that may occur because of Project implementation.
The Habitat Assessment is included as Appendix D to this EIR Addendum and its findings are incorporated into the
analysis herein.
Would the Project:

SWIP Specific Plan Update and Annexation PEIR Environmental Analysis
Almond Avenue Trailer Yard 4-15
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 California Department of Fish and Wildlife or U.S. Fish and Wildlife Service?
SWIP SP PEIR Finding: The SWIP SP PEIR determined that implementation of the SWIP SP had the potential to
result in direct and/or indirect impacts to sensitive species, including the Delhi Sands flower loving fly, burrowing
owl, northwestern San Diego pocket mouse, western pocket mouse, western mastiff bat, western yellow bat, and
San Diego desert woodrat. The SWIP SP PEIR also determined that portions of the SWIP SP area contain habitat
for the San Bernardino kangaroo rat, California gnatcatcher, and sensitive pocket mice. Lastly, the SWIP SP PEIR
determined that construction activities within the SWIP SP area could disturb/destroy active raptor and/or
migratory bird nests, which would be a violation of the Migratory Bird Treaty Act (MBTA). The SWIP SP PEIR
included MMs 4.3-1a through 4.3-1h to reduce potential impacts to sensitive species and migratory birds
(including the burrowing owl) to a level below significance.
Analysis of Project: The Project Site is developed, currently operating as an outdoor storage area for an active
concrete manufacturing facility, and is devoid of vegetation communities (Cadre, 2025, p. 3). Due to the developed
condition of the Project Site and the surrounding area, the Project Site has a low likelihood of supporting any of
the sensitive species identified in the SWIP SP PEIR as potentially occurring within the SWIP SP area (Cadre, 2025,
p. 27). No bird nests were observed on-site; however, birds have the potential to build nests on-site (Cadre, 2025,
p. 31). Accordingly, the Project would be required to comply with SWIP SP PEIR MM 4.3-1b to preclude substantial
impacts to nesting birds – this MM requires pre-construction nesting bird surveys in the event that construction
activities occur during the avian nesting season. In addition, the Project would be required to comply with MM
4.3-1c to preclude potential impacts to bats that may roost in trees on-Site. Implementation of the Project would
not result in any new or more severe impacts to sensitive wildlife or plant species than previously disclosed in the
SWIP SP PEIR.
Mitigation: No new or updated MMs are required. All applicable MMs identified in the SWIP SP PEIR to reduce
impacts related to sensitive plant and animal species continue to apply to the Project, as presented below and in
the MMRP for the SWIP SP PEIR (attached hereto as Appendix A).
MM 4.3-1b Any future land disturbance for site-specific developments within the Project Site shall be
conducted outside of the State-identified bird nesting season (February 15 through September
1). If construction during the nesting season must occur, the site shall be evaluated by a City-
approved biologist prior to ground disturbance to determine if nesting birds exist on-site. If any
nests are discovered, the biologist shall delineate an appropriate buffer zone around the nest,
depending on the species and type of construction activity. Only construction activities approved
by the biologist shall take place within the buffer zone until the nest is vacated.
MM 4.3-1c Prior to any ground disturbance, trees scheduled for removal shall be evaluated by a City-
approved biologist for roosting bats. If a roost is present the biologist will develop a plan to
minimize impacts to the bats to the greatest extent feasible.
Note: The following SWIP SP PEIR MMs do not apply to the Project or have been satisfied as part of the City’s
review of the Project’s proposed entitlement applications: MMs 4.3-1a, 4.3-1d, 4.3-1e, 4.3-1f, 4.3-1g, 4.3-1h do
Addendum to the
SWIP Specific Plan Update and Annexation PEIR Environmental Analysis
Almond Avenue Trailer Yard 4-16
not apply due to the developed/disturbed condition of the Project Site and the lack of natural or sensitive habitat
on-site; MM 4.3-3a does not apply due to the lack of natural drainage courses or wetlands on the Project Site.
b. Have a substantial adverse effect on any riparian habitat or other sensitive natural community identified
in local or regional plans, policies, and regulations or by the California Department of Fish and Wildlife or
U.S. Fish and Wildlife Service?
SWIP SP PEIR Finding: The SWIP SP PEIR concluded that implementation of the SWIP SP would not result in the
loss of riparian habitat but could result in the loss or degradation of Designated Critical Habitats of two Federally-
listed species: the San Bernardino kangaroo rat (SBKR) and the California gnatcatcher (CAGN). The SWIP SP PEIR
applied mitigation (i.e., MMs 4.3-1a through 4.3-1h) to future development projects within the SWIP SP area to
reduce potential impacts to sensitive natural communities to less than significant.
Analysis of Project: The Project Site is completely developed/disturbed and is currently operating as an outdoor
storage area for a concrete manufacturing facility. No riparian habitat or other sensitive natural communities
occur onsite. In addition, no jurisdictional resources regulated by the USACE, CDFW, or RWQCB are present within
or adjacent to the Project Site (Cadre, 2025, p. 30). Accordingly, the Project would not result in significant impacts
to riparian habitat or other sensitive natural communities. The City determined that the Project would not be
subject to MMs 4.3-1a through 4.3-1h, except for MMs 4.3-1b and 4.3-1c as described in the preceding subsection,
due to the lack of riparian habitat or potentially sensitive natural communities on the Project Site. Implementation
of the Project would not result in a new or more severe significant impacts to riparian habitats or sensitive natural
communities than previously disclosed in the SWIP SP PEIR.
c. Have a substantial adverse effect on State or federally protected wetlands (including, but not limited to,
marsh, vernal pool, coastal, etc.) through direct removal, filling, hydrological interruption, or other means?
SWIP SP PEIR Finding: The SWIP SP PEIR determined that there is a potential for streambeds, wetlands, and/or
riparian areas to occur within the SWIP SP area, and that impacts to these water features and vegetation may
require compliance with permit requirements of the U.S. Army Corps of Engineers (ACOE), Regional Water Quality
Control Board (RWQCB), and California Department of Fish and Game (CDFG). The SWIP SP PEIR included MM 4.3-
3a requiring jurisdictional delineations be performed for future development proposals that could potentially
affect jurisdictional drainages or wetlands. The SWIP SP PEIR concluded that implementation of SWIP SP PEIR MM
4.3-3a would reduce potential impacts to streambeds, wetlands, and/or riparian to a level below significance.
Analysis of Project: The Project Site is fully developed/disturbed and is currently operating as an active concrete
manufacturing facility, including storage and staging areas. No wetlands or other jurisdictional aquatic resources
are present within or adjacent to the Project Site (Cadre, 2025, p. 30). Accordingly, the Project would not result in
significant impacts to State or federally protected wetland. SWIP SP MM 4.3-3a would not be applicable to the
Project due to the lack of potential streambeds, wetlands, and/or riparian habitat on the Project Site.
Implementation of the Project would not result in any new or more severe significant impacts to State or federally
protected wetlands than previously disclosed in the SWIP SP PEIR.
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 wildlife nursery sites?
Addendum to the
SWIP Specific Plan Update and Annexation PEIR Environmental Analysis
Almond Avenue Trailer Yard 4-17
SWIP SP PEIR Finding: The SWIP SP PEIR determined that because the SWIP SP is surrounded by urban
development (paved roads, industrial, commercial and residential development, and the I-10 freeway) no
migratory corridors exist within or near the SWIP SP area that would be affected by the development of the SWIP
SP. The SWIP SP PEIR concluded impacts would be less than significant.
Analysis of Project: Under existing conditions, the Project Site has no wildlife habitat value due to its
developed/disturbed condition and lack of vegetation (Cadre, 2025, p. 27). Moreover, no local or regional wildlife
corridors are present within or adjacent to the Project Site (Cadre, 2025, p. 31). As such, implementation of the
Project would not interfere with the movement of any native resident or migratory wildlife species or with
established native resident or migratory wildlife corridors. Implementation of the Project would not result in any
new or more severe significant impacts to wildlife movement corridors than previously disclosed in the SWIP SP
PEIR.
e. Conflict with any local policies or ordinances protecting biological resources, such as a tree preservation
policy or ordinance?
SWIP SP PEIR Finding: The SWIP SP PEIR determined that implementation of the SWIP SP could involve the
removal of heritage, significant, or specimen trees. However, the SWIP SP PEIR concluded that all development
within the SWIP SP would be subject to compliance with Chapter 28 Article III of the City’s Municipal Code (which
establishes regulations for the protection and preservation of heritage trees, significant trees, and specimen trees
on public and private property). Accordingly, the SWIP SP PEIR concluded that mandatory compliance with
Chapter 28 Article III of the City’s Municipal Code would ensure that impacts associated with tree removals would
be less than significant.
Analysis of Project: The Project Applicant would be subject to mandatory compliance with Chapter 28 Article III
of the Fontana Municipal Code during the grading and building permit review processes and would be required to
demonstrate compliance to the City. Accordingly, the implementation of the Project would not conflict with the
City’s Tree Preservation Ordinance. There are no other local policies or ordinances protecting biological resources
that are applicable to the Project. Implementation of the Project would not result in any new or more severe
significant impacts due to a conflict with a local policies or ordinances protecting biological resources than
previously disclosed in the SWIP SP PEIR.
f. Conflict with the provisions of an adopted Habitat Conservation Plan, Natural Community Conservation
Plan, or other approved local, regional, or state habitat conservation plan?
SWIP SP PEIR Finding: The SWIP SP PEIR determined that buildout of the SWIP SP would not conflict with an
adopted habitat conservation plan because there were no adopted/approved habitat conservation plans
applicable to the SWIP SP area at the time that the SWIP SP PEIR was prepared. A recovery plan was released in
1997 for the Delhi Sands flower-loving fly that included the SWIP SP area; however, an assessment of the recovery
of Delhi Sands flower-loving fly in 2008 indicated that much of the Jurupa Recovery Unit may no longer provide
conservation value for Delhi Sands flower-loving fly. Regardless, the SWIP SP PEIR concluded that compliance with
the MMs included in the EIR would reduce potential impacts to the Delhi Sands flower-loving fly to a level below
significance.

SWIP Specific Plan Update and Annexation PEIR Environmental Analysis
Almond Avenue Trailer Yard 4-18
Analysis of Project: There are no habitat conservation plans or Natural Community Conservation Plans that are
applicable to the Project Site (CDFW, 2023). As disclosed in the SWIP SP PEIR, a recovery plan for the Delhi Sands
flower-loving fly was released in 1997 that included the SWIP SP area. However, based on soil data published by
the United States Department of Agriculture (USDA) Natural Resources Conservation Service and the Project’s
Biological Resources Assessment, the Project Site does not contain Delhi series soils, which are a requirement for
the species (USDA, 2019; Cadre, 2025, p. 18). Because there is no potential for the Project Site to support the Delhi
Sands flower-loving fly, implementation of the Project would not conflict with the provisions of the recovery plan
for the species. Accordingly, the Project would not conflict with the provisions of an applicable habitat
conservation plan or other approved local, regional, or State habitat conservation plan. Implementation of the
Project would not result in any new or more severe impacts related to conflicts with an adopted habitat
conservation plan, natural community conservation plan or other approved habitat conservation plan than
previously disclosed in the SWIP SP PEIR.
4.5 Cultural Resources
A Cultural Resources Study (dated October 20, 2025) (BFSA, 2025a) was prepared for the Project by Brian F. Smith
and Associated (BFSA) to identify potential archaeological and historical resources that may be affected by the
Project. This report includes the findings from an archaeological pedestrian survey; a cultural records search and
sacred lands search and an inventory of all recorded archaeological and historical resources located on the Project
Site and within a one-mile radius of the Project Site. This report is included as Appendix E to this EIR Addendum
and its findings are incorporated into the analysis presented herein.
Would the Project:
a. Cause a substantial adverse change in the significance of a historical resource pursuant to §15064.5?
SWIP SP PEIR Finding: The SWIP SP PEIR identified nine (9) historical resources in the SWIP SP area, none of which
were identified as significant historical resources under CEQA. Additionally, the SWIP SP PEIR determined that the
SWIP SP area has low sensitivity for historical resources. The SWIP SP PEIR included MMs that require future
development projects within the SWIP SP area to perform a pre-construction historical resources survey (and
implement a mitigation program if important resources are present) and to implement safeguards during grading
to protect/preserve historical resources that may be uncovered during grading activities (MMs 4.4-1a and 4.4-1b).
With application of the required MMs, the SWIP SP PEIR concluded that impacts to historic resources would be
less-than-significant.
Analysis of Project: In conformance with SWIP Specific Plan PEIR Mitigation Measure 4.4-1a, a historical resources
records search and assessment were conducted for the Project by BFSA. The South Central Coastal Information
Center (SCCIC) records search identified 36 resources within a one-mile radius of the Project Site, all of which are
historic. A portion of one recorded resource (Site SBR-4131H) overlaps the Project Site. Site SBR-4131H consists
of the historic Kaiser Steel Mill, established by Henry J. Kaiser as part of the Kaiser Steel Corporation and originally
opened in 1942. The boundary of Site SBR-4131H appears to have been loosely drawn, and although the mapped
area overlaps the Project Site, no physical remains of the historic resource have ever been documented within the
property. The Kaiser Steel Mill ceased operations in 1983, and by the 1990s, all major components of the former
facility had been demolished to accommodate redevelopment of the property as the California Speedway. As
Addendum to the
SWIP Specific Plan Update and Annexation PEIR Environmental Analysis
Almond Avenue Trailer Yard 4-19
such, for all practical purposes, Site SBR-4131H no longer exists today. (BFSA, 2025a, pp. 1.0-15 and 1.0-16)
Although the Kaiser Steel Mill remains listed in the California Register of Historical Resources (CRHR) as a Point of
Historical Interest, the physical integrity of the resource has been completely lost. (BFSA, 2025a, pp. 1.0-16)
Accordingly, implementation of the Project would not result in an adverse change in the significance of a historical
resource. The Project would not result in a new or more severe significant impact to historical resources than
previously disclosed in the SWIP SP PEIR.
Mitigation: No new or updated MMs are required. All applicable MMs identified in the SWIP SP PEIR to reduce
impacts to cultural resources continue to apply to the Project as listed below and in the MMRP for the SWIP SP
PEIR (attached hereto as Appendix A).
MM 4.4-1b If any historical resources are encountered before or during grading, the developer shall retain a
qualified archaeologist to monitor construction activities and to take appropriate MMs to protect
or preserve them for study.
Note: MM 4.4-1a was satisfied by the Cultural Resources Study (Appendix E) that was prepared for the Project.
b. Cause a substantial adverse change in the significance of an archaeological resource pursuant to
§15064.5?
SWIP SP PEIR Finding: The SWIP SP PEIR determined that no archaeological resources or Native American sites
exist within the SWIP SP area, and that the likelihood of encountering potentially significant prehistoric
archaeological resources within the SWIP SP area is considered low. The City of Fontana consulted with the Soboba
Band of Luiseño Indians and the Morongo Band of Mission Indians as part of the Senate Bill 18 (SB 18) Native
American tribal consultation process for the SWIP SP. The Soboba Band of Luiseño Indians identified the site as
being located within the tribe’s Tribal Traditional Use Area. The SWIP SP PEIR included MMs to minimize impacts
related to Native American resources and previously undiscovered archaeological resources that could be
encountered during ground disturbing activities (MMs 4.4-2a through 4.4-2c). Following implementation of
mitigation, the SWIP SP PEIR concluded that implementation of the SWIP SP would result in less-than-significant
impacts to prehistoric archaeological resources.
Analysis of Project: The Project Site was surveyed by BFSA for the presence of prehistoric archaeological resources
in accordance with SWIP SP PEIR MM 4.4-2a. No cultural resources were identified within the Project Site during
the archaeological records search and pedestrian survey. The report concludes there is little to no potential for
archaeological resources to be encountered due to previous grading and ground disturbance. (BFSA, 2025a, pp.
4.0-1) However, as a standard practice for all development projects in Fontana, the City would require the Project
Applicant to comply with conditions of approval that establish protocols for consultation, monitoring, and
resource recovery to protect inadvertent discoveries of buried/masked prehistoric archaeological resources. The
City’s standard conditions of approval are consistent with SWIP SP PEIR MM 4.4-2b, which requires the Project
Applicant to retain a qualified archaeological monitor during grading activities and implement a mitigation
recovery program, and SWIP SP PEIR MM 4.4-2c, which requires the Project Applicant to consider the requests of
the Soboba Band of Luiseño Indians and Morongo Band of Mission Indians concerning procedures for the
treatment of any Native American cultural resources. Compliance with the City’s standard conditions of approval,
which would ensure compliance with mitigation measures from the SWIP SP PEIR, would ensure the Project’s
Addendum to the
SWIP Specific Plan Update and Annexation PEIR Environmental Analysis
Almond Avenue Trailer Yard 4-20
potential impacts to archaeological resources would be less than significant. The SWIP SP EIR assumed that the
Project Site would be fully developed. Implementation of the Project would not result in any new or more severe
significant impacts to archaeological resources than previously disclosed in the SWIP SP PEIR.
Standard Condition of Approval: The City requires the following condition of approval of all discretionary
development approvals:
Upon discovery of any tribal cultural or archaeological resources, cease construction activities in
the immediate vicinity of the find until the find can be assessed. All tribal cultural and
archaeological resources unearthed by project construction activities shall be evaluated by the
qualified archaeologist and tribal monitor/consultant. If the resources are Native American in
origin, interested Tribes (as a result of correspondence with area Tribes) shall coordinate with the
landowner regarding treatment and curation of these resources. Typically, the Tribe will request
preservation in place or recovery for educational purposes. Work may continue on other parts of
the project while evaluation takes place.
Preservation in place shall be the preferred manner of treatment. If preservation in place is not
feasible, treatment may include implementation of archaeological data recovery excavation to
remove the resource along the subsequent laboratory processing and analysis. All Tribal Cultural
Resources shall be returned to the Tribe. Any historic archaeological material that is not Native
American in origin shall be curated at a public, non-profit institution with a research interest in the
materials, if such an institution agrees to accept the material. If no institution accepts the
archaeological material, they shall be offered to the Tribe or a local school or historical society in
the area for educational purposes.
Archaeological and Native American monitoring and excavation during construction projects shall
be consistent with current professional standards. All feasible care to avoid any unnecessary
disturbance, physical modification, or separation of human remains and associated funerary
objects shall be taken. Principal personnel shall meet the Secretary of the Interior standards for
archaeology and have a minimum of 10 years’ experience as a principal investigator working with
Native American archaeological sites in southern California. The Qualified Archaeologist shall
ensure that all other personnel are appropriately trained and qualified.
Mitigation: No new or updated MMs are required. All applicable MMs identified in the SWIP SP PEIR to reduce
impacts to cultural resources continue to apply to the Project as listed below and in the MMRP for the SWIP SP
PEIR (attached hereto as Appendix A).
MM 4.4-2b If any prehistoric archaeological resources are encountered before or during grading, the
developer shall retain a qualified archaeologist to monitor construction activities and to take
appropriate MMs to protect or preserve them for study. With the assistance of the archaeologist,
the City of Fontana shall:
• Enact interim MMs to protect undesignated sites from demolition or significant modification
without an opportunity for the City to establish its archaeological value.
Addendum to the
SWIP Specific Plan Update and Annexation PEIR Environmental Analysis
Almond Avenue Trailer Yard 4-21
• Consider establishing provisions to require incorporation of archaeological sites within new
developments, using their special qualities at a theme or focal point.
• Pursue educating the public about the area’s archaeological heritage.
• Propose MMs and recommend conditions of approval (if a local government action) to
eliminate adverse project effects on significant, important, and unique prehistoric resources,
following appropriate CEQA guidelines.
• Prepare a technical resources management report, documenting the inventory, evaluation,
and proposed mitigation of resources within the project area. Submit one copy of the
completed report, with original illustrations, to the San Bernardino County Archaeological
Information Center for permanent archiving.
MM 4.4-2c Where consistent with applicable local, State and federal law and deemed appropriate by the City,
future site-specific development projects shall consider the following requests by the Soboba
Band of Luiseño Indians and Morongo Band of Mission Indians:
• In the event Native American cultural resources are discovered during construction for future
development, all work in the immediate vicinity of the find shall cease and a qualified
archaeologist meeting Secretary of Interior standards shall be hired to assess the find. Work
on the overall project may continue during this period;
• Initiate consultation between the appropriate Native American tribal entity (as determined
by a qualified archaeologist meeting Secretary of Interior standards) and the City/project
applicant;
• Transfer cultural resources investigations to the appropriate Native American entity (as
determined by a qualified archaeologist meeting Secretary of Interior standards) as soon as
possible;
• Utilize a Native American Monitor from the appropriate Native American entity (as
determined by a qualified archaeologist meeting Secretary of Interior standards) where
deemed appropriate or required by the City, during initial ground disturbing activities, cultural
resource surveys, and/or cultural resource excavations.
Note: MM 4.4-1a was satisfied by the Cultural Resources Study (Appendix E) prepared for the Project.
c. Disturb any human remains, including those interred outside of formal cemeteries?
SWIP SP PEIR Finding: The SWIP SP PEIR did not identify any cemeteries or archaeological sites that may contain
human remains within the SWIP SP area. The SWIP SP PEIR concluded that with mandatory compliance with the
California Health and Safety Code Section 7050.5-7055 and Section 5097.98 of the California Public Resources
Code, the SWIP SP would result in less-than-significant impacts with respect to disturbance of human remains.
Analysis of Project: The Project Site does not contain a known cemetery. While not anticipated, in the unlikely
event that human remains are discovered during Project grading or other ground-disturbing activities, the Project
would be required to comply with the applicable provisions of California Health and Safety Code Section 7050.5
as well as Public Resources Code Section 5097 et. seq. Mandatory compliance with these provisions of California
state law would require that human remains, if unearthed during construction activities, to be appropriately
Addendum to the
SWIP Specific Plan Update and Annexation PEIR Environmental Analysis
Almond Avenue Trailer Yard 4-22
treated thereby ensuring that Project impacts would be less than significant. The SWIP SP PEIR assumed that the
Project Site would be fully developed. Implementation of the Project would not result in new or more severe
significant impacts related to the potential discovery of human remains than previously disclosed in the SWIP SP
PEIR.
4.6 Energy
Energy was not an independent CEQA topic in 2012 when the SWIP SP PEIR was certified 1. Although no stand-
alone Energy Analysis was prepared for this Project, the Project’s anticipated energy use is limited to typical office
and site-lighting demands associated with an outdoor trailer storage yard. As discussed in this section, the Project
would comply with applicable Title 24 and CALGreen requirements and would not result in inefficient, wasteful,
or unnecessary consumption of energy during construction or operation.
Would the Project:
a. Result in potentially significant environmental impact due to wasteful, inefficient, or unnecessary
consumption of energy resources, during project construction or operation?
SWIP SP PIER Finding: While energy was not a specifically called out topic at the time, the SWIP SP PEIR was
prepared, it nonetheless analyzed potential impacts in this regard and concluded that implementation of the SWIP
SP, including construction and operation, would not result in wasteful or unjustifiable consumption of energy
resources.
Analysis of Project: While energy was not an independent CEQA topic when the SWIP SP PEIR was certified, the
PEIR nonetheless evaluated energy consumption associated with implementation of the SWIP SP and concluded
that construction and operation of land uses within the Plan area would not result in wasteful or unjustifiable
consumption of energy resources. The Project is consistent with the SWIP SP land use plan and development
intensity; therefore, the Project’s energy demand falls within the scope of what was previously evaluated in the
SWIP SP PEIR.
Construction Energy
Project construction would require temporary electricity and fuel consumption associated with grading, paving,
utility installation, and construction of the onsite office and guard station. Construction-related energy use would
be typical for a project of this type and limited in duration. Construction equipment is required to comply with
California Air Resources Board (CARB) emissions and efficiency standards, which serve to minimize fuel
consumption and prohibit unnecessary idling. Because construction energy demand would be short term, typical
for similar site-improvement projects, and not require a permanent or ongoing commitment of energy resources,
construction energy use would not be considered wasteful, inefficient, or unnecessary.
1 Changes in CEQA analytical methodologies, significance thresholds, or regulatory requirements do not constitute “new information”
requiring supplemental environmental review where the underlying environmental issue was known and addressed at the time the prior
EIR was certified. (Concerned Dublin Citizens v. City of Dublin (2013) 214 Cal.App.4th 1301, 1320; Olen Properties Corp. v. City of Newport
Beach (2023) 93 Cal.App.5th 270, 280; Hilltop Group Inc. v. County of San Diego (2024) 99 Cal.App.5th 890.)
Addendum to the
SWIP Specific Plan Update and Annexation PEIR Environmental Analysis
Almond Avenue Trailer Yard 4-23
Operational Energy
During long-term operation, the Project’s energy use would be limited primarily to: electricity for site lighting,
security systems, and the small onsite office and guard station; and transportation fuel associated with employee
vehicle trips and truck movements related to trailer drop-offs and pick-ups. The Project does not include
warehouse distribution operations, cold storage, manufacturing, or other energy-intensive uses. As such,
operational energy demand would be substantially lower than the warehouse development scenario considered
in the SWIP SP PEIR. The Project is required to comply with current Title 24 and CALGreen building efficiency
standards, which are more stringent than those in effect at the time the SWIP SP PEIR was certified. These
standards ensure that building energy use is minimized and not wasteful or inefficient.
Vehicle-related fuel consumption would also be less than the levels assumed in the SWIP SP PEIR because the
Project generates substantially fewer daily vehicle trips than the warehouse scenario evaluated in the original
PEIR.
Conclusion
Based on the limited and non–energy-intensive nature of Project operations and mandatory compliance with
State energy efficiency requirements, the Project would not result in the wasteful, inefficient, or unnecessary
consumption of energy resources during construction or operation. Implementation of the Project would not
result in new or more severe energy-related impacts than those disclosed in the SWIP SP PEIR.
Mitigation: No new or updated MMs are required. All applicable MMs identified in the SWIP SP PEIR to maximize
energy efficiency continue to apply to the Project as listed below and included in the MMRP for the SWIP SP PEIR
(attached hereto as Appendix A).
MM 4.2-5a Prior to the issuance of building permits, future development projects shall demonstrate the
incorporation of project design features that achieve a minimum of 28.5 percent reduction in GHG
emissions from business as usual conditions. Future projects shall include, but not be limited to,
the following list of potential design features.
Energy Efficiency
• Design buildings to be energy efficient and exceed Title 24 requirements by at least 5 percent.
• Install efficient lighting and lighting control systems. Site and design building to take
advantage of daylight.
• Use trees, landscaping and sun screens on west and south exterior building walls to reduce
energy use.
• Install light colored “cool” roofs and cool pavements.
• Provide information on energy management services for large energy users.
• Install energy efficient heating and cooling systems, appliances and equipment, and control
systems (e.g., minimum of Energy Star rated equipment).
• Implement design features to increase the efficiency of the building envelope (i.e., the barrier
between conditioned and unconditioned spaces).
• Install light emitting diodes (LEDs) for traffic, street and other outdoor lighting.
Addendum to the
SWIP Specific Plan Update and Annexation PEIR Environmental Analysis
Almond Avenue Trailer Yard 4-24
• Limit the hours of operation of outdoor lighting.
Renewable Energy
• Install solar panels on carports and over parking areas. Ensure buildings are designed to have
“solar ready” roofs.
• Use combined heat and power in appropriate applications.
• Water Conservation and Efficiency
• Create water-efficient landscapes with a preference for a xeriscape landscape palette.
• Install water-efficient irrigation systems and devices, such as soil moisture-based irrigation
controls.
• Design buildings to be water-efficient. Install water-efficient fixtures and appliances (e.g., EPA
WaterSense labeled products).
• Restrict watering methods (e.g., prohibit systems that apply water to non-vegetated surfaces)
and control runoff.
• Restrict the use of water for cleaning outdoor surfaces and vehicles.
• Implement low-impact development practices that maintain the existing hydrologic character
of the site to manage storm water and protect the environment. (Retaining storm water
runoff on-site can drastically reduce the need for energy-intensive imported water at the site).
• Devise a comprehensive water conservation strategy appropriate for the project and location.
The strategy may include many of the specific items listed above, plus other innovative MMs
that are appropriate to the specific project.
• Provide education about water conservation and available programs and incentives.
Solid Waste MMs
• Reuse and recycle construction and demolition waste (including, but not limited to, soil,
vegetation, concrete, lumber, metal, and cardboard).
• Provide interior and exterior storage areas for recyclables and green waste and adequate
recycling containers located in public areas.
• Provide education and publicity about reducing waste and available recycling services.
Transportation and Motor Vehicles
• Limit idling time for commercial vehicles, including delivery and construction vehicles.
• Promote ride sharing programs (e.g., by designating a certain percentage of parking spaces
for ride sharing vehicles, designating adequate passenger loading and unloading and waiting
areas for ride sharing vehicles, and providing a web site or message board for coordinating
rides).
• Create local “light vehicle” networks, such as neighborhood electric vehicle (NEV) systems.
• Provide the necessary facilities and infrastructure to encourage the use of low or zero-
emission vehicles (e.g., electric vehicle charging facilities and conveniently located alternative
fueling stations).
• Promote “least polluting” ways to connect people and goods to their destinations.
• Incorporate bicycle lanes and routes into street systems, new subdivisions, and large
developments.
Addendum to the
SWIP Specific Plan Update and Annexation PEIR Environmental Analysis
Almond Avenue Trailer Yard 4-25
• Incorporate bicycle-friendly intersections into street design.
• For commercial projects, provide adequate bicycle parking near building entrances to
promote cyclist safety, security, and convenience. For large employers, provide facilities that
encourage bicycle commuting (e.g., locked bicycle storage or covered or indoor bicycle
parking).
• Create bicycle lanes and walking paths directed to the location of schools, parks and other
destination points.
b. Conflict with or obstruct a state or local plan for renewable energy or energy efficiency?
SWIP SP PEIR Finding: Although the SWIP SP PEIR did not specifically address this question, the SWIP SP PEIR
disclosed that all future development within the SWIP SP area would be required to comply with Title 24 of the
California Code of Regulation (of which Part 6 establishes the State’s Building Energy Efficiency Standards),
development standards and design requirements related to sustainability and energy conservation contained in
the City of Fontana Municipal Code, and current and future State legislation, executive orders, and regulatory
guidance to maximize energy efficiency. Furthermore, the SWIP SP PEIR also acknowledged that it was probable
that new technologies would emerge and be incorporated into future development to reduce energy
consumption. Lastly, the SWIP SP PEIR included a MM (MM 4.2-5a) that would require future development to
incorporate design features that would minimize the consumption of energy.
Analysis of Project: The Project would not conflict with or obstruct a State or local plan for renewable energy or
energy efficiency. As acknowledged in the SWIP SP PEIR, all development within the SWIP SP area is required to
comply with the California Building Energy Efficiency Standards (Title 24, Part 6), CALGreen requirements, and
applicable sustainability and energy conservation provisions of the City of Fontana Municipal Code. These
requirements have become more stringent since certification of the SWIP SP PEIR and ensure that new
development incorporates energy-efficient design features and building systems.
The Project consists of a paved trailer storage yard with a small onsite office building and guard station, which are
not energy-intensive land uses. Mandatory compliance with the most current Title 24 and CALGreen standards,
as well as SWIP SP PEIR MM 4.2-5a, would ensure that the Project’s limited building energy use is minimized and
does not conflict with State or local plans aimed at promoting renewable energy or energy efficiency.
Mitigation: No new or updated MMs are required. SWIP SP PEIR MM 4.2-5a, as presented above and in the MMRP
for the SWIP SP PEIR, attached hereto as Appendix A, continue to apply to the Project.
Monitoring: Monitoring shall occur as specified in the MMRP for the SWIP SP PEIR; refer to Appendix A.
4.7 Geology and Soils
A Geotechnical Investigation (dated September 9, 2025) (TGR, 2025) was prepared for the Project by TGR
Geotechnical, Inc. (TGR) to evaluate the geotechnical conditions of the subject property, identify any geological
hazards, and provide recommendations for the future development of the Project. Additionally, a Paleontological
Resources Assessment (October 20, 2025) (BFSA, 2025b), was prepared by BFSA to evaluate the potential for the
Project Site to contain significant, non-renewable paleontological (fossil) resources. These reports are included as
Addendum to the
SWIP Specific Plan Update and Annexation PEIR Environmental Analysis
Almond Avenue Trailer Yard 4-26
Appendices F and M, respectively, to this EIR Addendum and their findings are incorporated into the analysis
presented herein.
Would the Project:
a. Directly or indirectly cause potential substantial adverse effects, including the risk of loss, injury or death
involving:
i. Rupture of a known earthquake fault, as delineated on the most recent Alquist-Priolo Earthquake
Fault Zoning Map issued by the State Geologist for the area or based on other substantial evidence
of a known fault? Refer to Division of Mines and Geology Special Publication 42.
SWIP SP PEIR Finding: The SWIP SP PEIR determined that there are no Alquist-Priolo earthquake faults located
within the SWIP SP area. The nearest fault to the SWIP SP area is the Cucamonga Fault which traverses through
the northern portion of the City of Fontana approximately 7.0 miles north of the SWIP SP area. The SWIP SP PEIR
concluded that because no known earthquake faults are known to exist beneath the SWIP SP area, impacts related
to fault rupture would be less than significant.
Analysis of Project: According to the TGR Geotechnical Report (2025), the Project Site is located within a
seismically active region; however, it is not located within an Alquist-Priolo Earthquake Fault Zone (TGR, 2025, p.
3). In addition, the geotechnical report indicates that there are no Holocene-active, pre-Holocene, or age-
undetermined faults located within or immediately adjacent to the subject property, and therefore surface fault
rupture is not anticipated. (TGR, 2025, p. 3) The nearest mapped fault is an unnamed inferred fault approximately
0.6 mile southeast of the Site, with the Red Hill-Etiwanda Avenue, Cucamonga (Sierra Madre) Fault Zone, and San
Jacinto Fault (San Bernardino Valley section) located between roughly 5 and 7 miles from the Site (TGR, 2025, p.
4). Accordingly, the Project would not expose people or structures to adverse effects from fault rupture, and
implementation of the Project would not result in any new or more severe impacts than those previously
evaluated in the SWIP PEIR.
ii. Strong seismic ground shaking?
SWIP SP PEIR Finding: The SWIP SP PEIR determined that development within the SWIP SP area could be exposed
to strong seismic ground shaking due to the numerous active faults located in the southern California region. The
SWIP SP PEIR concluded that future development’s adherence to standard engineering practices and design
criteria relative to seismic and geologic hazards in accordance with the California Building Code (CBC) would
reduce the significance of impacts related to seismic ground shaking to a level below significance.
Analysis of Project: The Project Site is in a seismically active area of Southern California and is anticipated to
experience moderate-to-severe ground shaking during the Project’s lifetime (TGR, 2025, p. 3). This risk is not
considered substantially different than that of other similar properties in the Southern California area. Consistent
with the conclusion in the SWIP SP PEIR concerning impacts related to seismic ground shaking, the Project is
required to adhere to standard engineering practices and design criteria relative to seismic and geologic hazards
in accordance with the CBC, including the California Building Standards Code (CBSC), also known as California Code
of Regulations (CCR), Title 24 (Part 2), and the Fontana Building Code, which is based on the CBSC with local
amendments. The CBSC and Fontana Building Code provide standards that must be met to safeguard life or limb,
Addendum to the
SWIP Specific Plan Update and Annexation PEIR Environmental Analysis
Almond Avenue Trailer Yard 4-27
health, property, and public welfare by regulating and controlling the design, construction, quality of materials,
use and occupancy, location, and maintenance of all buildings and structures, and these standards have been
specifically tailored for California earthquake conditions. In addition, TGR provided recommendations for
construction of the Project to minimize on-site hazards from strong seismic ground shaking, which will be
implemented as one of the City’s conditions of Project approval. The SWIP SP PEIR assumed the Project Site would
be fully developed. With mandatory compliance with State and local building standards, the Project would not
expose people and structures to substantial adverse effects, including loss, injury, or death, involving seismic
ground shaking. The Project would result in new or more severe significant impacts related to seismic ground-
shaking than previously disclosed in the SWIP SP PEIR.
iii. Seismic-related ground failure, including liquefaction?
SWIP SP PEIR Finding: The SWIP SP PEIR determined that although the potential exists for liquefaction to occur
within the SWIP SP area, future development within the SWIP SP would be subject to site-specific geotechnical
investigations and would comply with existing CBSC standards to minimize any potential ground failure or
liquefaction hazards. Accordingly, the SWIP SP PEIR concluded that implementation of the SWIP SP would not
expose people or structures to potential impacts related to seismic ground failure or liquefaction.
Analysis of Project: The Project Site is not within an area of liquefaction susceptibility (TGR, 2025, p. 4).
Accordingly, the Project would not expose people or structures to substantial adverse effects, including loss,
injury, or death, involving liquefaction. The SWIP SP PEIR assumed the Project Site would be fully developed.
Therefore, the Project would not result in new or more severe significant impacts related to liquefaction than
previously disclosed in the SWIP SP PEIR.
iv. Landslides?
SWIP SP PEIR Finding: The SWIP SP PEIR concluded that the risk of landslides in the SWIP SP area is low due to the
relatively flat topography of the SWIP SP area. The SWIP SP PEIR concluded that no impact would occur with
regard to landslides.
Analysis of Project: The Project Site is flat and has no substantial natural or man-made slopes under existing
conditions. Additionally, there are no substantial natural or man-made slopes in proximity to the Project Site.
Therefore, the potential for landslides on- or off-site is low. Proposed grading would not create manufactured
slopes; therefore, implementation of the Project would not create a landslide risk to surrounding properties. The
SWIP SP PEIR assumed the Project Site would be fully developed. The Project would not result in new or more
severe significant impacts related to landslide than previously disclosed in the SWIP SP PEIR.
b. Result in substantial soil erosion or the loss of topsoil?
SWIP SP PEIR Finding: The SWIP SP PEIR concluded that compliance with all requirements set forth in the National
Pollutant Discharge Elimination System (NPDES) permit for construction activities (e.g., implementation of BMPs
through preparation of a Stormwater Pollution Prevention Plan [SWPPP]) would preclude potential soil erosion
impacts.
Addendum to the
SWIP Specific Plan Update and Annexation PEIR Environmental Analysis
Almond Avenue Trailer Yard 4-28
Analysis of Project: The analysis below summarizes the likelihood of the Project to result in substantial soil erosion
during temporary construction activities and/or long-term operation. As demonstrated in the analysis below,
implementation of the Project would not result in substantial effects related to soil erosion or the loss of topsoil.
Implementation of the Project would not result in any new impacts or more severe significant impacts related to
soil erosion than previously disclosed in the SWIP SP PEIR, which assumed the Project Site would be fully
developed.
Construction Activities
Project construction would involve clearing, grading, excavation, paving, utility installation, placement of a
prefabricated office building, and landscaping installation, which has the potential to temporarily expose on-site
soils that are currently covered by concrete and could be subject to erosion during rainfall events or high winds.
Pursuant to State Water Resources Control Board requirements, the Project Applicant would be required to obtain
coverage under the State’s General Construction Storm Water Permit for construction activities (NPDES permit).
The NPDES permit is required for all projects that include construction activities, such as clearing, grading, and/or
excavation that disturb at least one (1) acre of total land area. Compliance with the NPDES Permit requires the
Project Applicant to prepare and submit to the City for approval a Project-specific SWPPP. The SWPPP would
identify a combination of erosion control and sediment control MMs (i.e., BMPs) to reduce or eliminate sediment
discharge to surface water from stormwater and non-stormwater discharges during construction. In addition, the
Project would be required to comply with SCAQMD Rule 403, which establishes requirements for the control of
dust during construction (including wind erosion) (SCAQMD, 2005b). With mandatory compliance to the
requirements noted in the Project’s SWPPP, as well as applicable regulatory requirements, there would be no
potential for substantial water and/or wind erosion impacts during Project construction. Implementation of the
Project would not result in any new or more severe significant impacts related to soil erosion than previously
disclosed in the SWIP SP PEIR.
Operational Activities
Upon Project build-out, the Project Site would be redeveloped with a paved trailer parking facility, prefabricated
office building, and landscaping. Stormwater runoff from the Site would be captured and treated to reduce
pollutants, including sediment, prior to discharge. A portion of on-site runoff would be routed to on-site
infiltration and treatment facilities, while excess runoff would be conveyed off-site via the on-site storm drain
system.
The City’s Municipal Storm Water Permit will require the Project Applicant to prepare and implement a WQMP
(see City of Fontana Municipal Code Section 5-14, Compliance with the NPDES Permit, & Chapter 23, Article IX,
Preventing Discharge of Pollutants into Storm Drains). The WQMP is required to identify an effective combination
of erosion control and sediment control best management practices (BMPs) to reduce or eliminate sediment
discharge to surface water from stormwater and non-stormwater discharges. The Preliminary WQMP for the
Project is attached hereto as Appendix I. Compliance with the WQMP would be required as a condition of Project
approval, and long-term maintenance of on-site water quality features is required. Because the Project would be
required to utilize erosion and sediment control MMs to preclude substantial, long-term soil erosion and loss of
topsoil, substantial soil erosion would not occur. Implementation of the Project would not result in any new or
more severe significant impacts related to soil erosion than previously disclosed in the SWIP SP PEIR.

c. Be located on a geologic unit or soil that is unstable, or that would become unstable as a result of the
project, and potentially result in on- or off-site landslide, lateral spreading, subsidence, liquefaction, or
collapse?
SWIP SP PEIR Finding: The SWIP SP PEIR determined that the SWIP SP area is not located on a geologic unit or soil
that is unstable, or that would become unstable as a result of the project and potentially result in on- or off-site
landslide, lateral spreading, subsidence, liquefaction, or collapse. The SWIP SP EIR concluded that a less-than-
significant impact would occur.
Analysis of Project: The Project Site contains previously disturbed soils and fill that could be subject to settlement
if not properly prepared. However, the Geotechnical Investigation provides site preparation, grading, and
engineered fill recommendations that would reduce potential settlement and instability hazards to acceptable
levels (TGR, 2025, p. 8). The Project would be required to implement the design, grading, and construction
recommendations within its Geotechnical Investigation pursuant to City Municipal Code Chapter 26, Division 4,
Investigation of Soil Conditions, which would ensure that the Project Site’s soils remain stable post-development.
(The City would assign a condition of approval to the Project requiring implementation of the Geotechnical
Investigation pursuant to Municipal Code Chapter 26, Division 4.) Based on the foregoing analysis, implementation
of the Project would not expose people or structures to significant hazards related to unstable soils.
Implementation of the Project would not result in any new impacts or more severe significant impacts related to
unstable soils than previously disclosed in the SWIP SP PEIR.
d. Be located on expansive soil, as defined in Table 18-1- B of the Uniform Building Code (since renamed as
the California Building Code), creating substantial direct or indirect risks to life or property?
SWIP SP PEIR Finding: The SWIP SP PEIR determined that soils in portions of the SWIP SP area are susceptible to
expansion. However, the SWIP SP PEIR concluded that because future development within the SWIP SP would be
subject to site-specific geotechnical investigations and would be required to comply with CBSC standards
addressing expansive soil hazards, impacts associated with expansive soils would be less than significant.
Analysis of Project: The Project would be designed and constructed in accordance with the California Building
Code and the recommendations provided in the project-specific Geotechnical Report. The Geotechnical Report
includes grading and foundation recommendations and notes that slab design should consider the expansion
index of the soil. (TGR, 2025, pp. 6-7) Therefore, the Project would not create substantial direct or indirect risks
to life or property related to expansive soils. The SWIP SP PEIR assumed the Project Site would be fully developed.
Implementation of the Project would not result in any new impacts or more severe significant impacts related to
expansive soil than previously disclosed in the SWIP SP PEIR.
e. Have soils incapable of adequately supporting the use of septic tanks or alternative wastewater disposal
systems where sewers are not available for the disposal of wastewater?
SWIP SP PEIR Finding: The SWIP SP PEIR did not identify any significant adverse effects related to septic systems,
because the SWIP SP would be served by sewer facilities and therefore not entail the installation of septic tanks
or alternative wastewater disposal systems.
Addendum to the
SWIP Specific Plan Update and Annexation PEIR Environmental Analysis
Almond Avenue Trailer Yard 4-30
Analysis of Project: The Project would connect to the municipal sewer system and does not propose the use of
septic tanks or alternative waste water disposal systems. Implementation of the Project would not result in any
new impacts or more severe significant impacts related to septic tanks or alternative wastewater disposal systems
than previously disclosed in the SWIP SP PEIR.
f. Directly or indirectly destroy a unique paleontological resource or site or unique geologic feature?
SWIP SP PEIR Finding: The SWIP SP PEIR disclosed that the southern portion of the SWIP SP area is underlain by
Pleistocene older fan deposits, which have a high potential to contain important fossil resources. The SWIP SP
PEIR included MMs 4.4-3a and 4.4-3b which require future development projects within the SWIP SP to analyze
potential impacts to paleontological resources on a site-specific basis prior to construction and, then, implement
any recommended mitigation program (if required). The SWIP SP PEIR concluded that with implementation of
mitigation, the SWIP SP would result in less-than-significant impacts to paleontological resources.
Analysis of Project: In accordance with SWIP SP PEIR MM 4.4-3a, a Paleontological Resources Assessment
(Appendix M), was prepared for the Project Site by BFSA. The Paleontological Assessment concluded that the
Project Site is underlain by Holocene-age young alluvial fan deposits (Qyf5), which have a low paleontological
sensitivity, but that these younger deposits are likely underlain by older, late Pleistocene alluvial fan deposits
(Qyf1) (BFSA, 2025b, p. 10). Older Pleistocene deposits, specifically in the Inland Empire, have a high
paleontological sensitivity. Accordingly, BFSA concluded that the strata underlying the Project Site has the
potential to contain important fossil deposits and recommended paleontological monitoring be performed during
the Project’s grading, excavation, or utility trenching activities that occur at or below 5 feet below the existing
ground surface (ibid.). The Project’s monitoring program would be required to comply with the performance
standards established by SWIP SP PEIR MM 4.4-3b. With compliance with SWIP SP PEIR MM 4.4-3b, the Project
would minimize the significance of the Project’s potential effects to important paleontological resources to less-
than-significant levels. This conclusion is consistent with the conclusion from the SWIP SP PEIR, which assumed
the Project Site would be fully developed. Implementation of the Project would not result in any new or more
severe significant impacts to paleontological resources than previously disclosed in the SWIP SP PEIR.
Mitigation: No new MMs are required. All applicable MMs identified in the SWIP SP PEIR to reduce impacts to
paleontological resources continue to apply to the Project, as listed below and included in the MMRP for the SWIP
SP PEIR (attached hereto as Appendix A).
MM 4.4-3b Should mitigation monitoring be recommended for a specific project within the Project Site, the
program shall include, but not be limited to, the following MMs:
• Assign a paleontological monitor, trained, and equipped to allow the rapid removal of fossils
with minimal construction delay, to the site full-time during the interval of earth-disturbing
activities.
• Should fossils be found within an area being cleared or graded, earth-disturbing activities shall
be diverted elsewhere until the monitor has completed salvage. If construction personnel
make the discovery, the grading contractor shall immediately divert construction and notify
the monitor of the find.
Addendum to the
SWIP Specific Plan Update and Annexation PEIR Environmental Analysis
Almond Avenue Trailer Yard 4-31
• All recovered fossils shall be prepared, identified, and curated for documentation in the
summary report and transferred to an appropriate depository (i.e., San Bernardino County
Museum).
• A summary report shall be submitted to City of Fontana. Collected specimens shall be
transferred with copy of report to San Bernardino County Museum.
Note: MM 4.4-3a was satisfied by the Paleontological Resources Assessment (Appendix N) that was prepared for
the Project. The Assessment recommends preparation of a Paleontological Resources Impact Mitigation Program
(PRIMP), including paleontological monitoring during grading and trenching activities. This recommendation is
consistent with SWIP SP PEIR MM 4.4-3b and does not represent a new or modified mitigation measure.
4.8 Greenhouse Gas Emissions
A Greenhouse Gas Assessment (dated February 16, 2026) (Urban Crossroads, 2026a) was prepared for the Project
by Urban Crossroads to quantify the GHG emissions that would result from Project-related construction and
operational activities. This report is included as Appendix B to this EIR Addendum and its findings are incorporated
into the analysis presented herein.
Would the Project:
a. Generate greenhouse gas emissions, either directly or indirectly, that may have a significant impact on the
environment?
b. Conflict with any applicable plan, policy, or regulation of an agency adopted for the purpose of reducing
the emissions of greenhouse gases?
SWIP SP PEIR Finding: The SWIP SP PEIR disclosed that implementation of the SWIP SP would result in GHG
emissions equal to 1,147,515.21 MTCO2eq/year absent project design features and mitigation. The SWIP SP PEIR
included mitigation (MM 4.2-5a) that would require the individual development projects within the SWIP SP area
to incorporate sustainable practices related to water usage, energy usage, solid waste generation, and
transportation. The SWIP SP PEIR determined that implementation of the reduction MMs required by MM 4.2-5a
would reduce GHG emission from buildout of the SWIP SP to 774,572.77 MTCO2eq/year (an approximate 32.5
percent reduction relative to the unmitigated emissions). The SWIP SP PEIR determined that because MM 4.2-5
would result in GHG reductions that would exceed the mandate of Assembly Bill (AB) 32, that implementation of
the SWIP SP would not generate GHG emissions that have a significant impact on the environment and, also, that
the SWIP SP would be consistent with applicable plans and policies related GHG emissions reductions.
Analysis of Project: The Project’s annual GHG emissions are summarized in Table 4-7, Annual Project Greenhouse
Gas Emissions. The GHG emissions reported in Table 4-7 are unmitigated and do not account for any mitigation
required by the SWIP SP PEIR. The methodology used to quantify the Project’s annual GHG emission is described
in the Project’s Greenhouse Gas Assessment (see Appendix A).

The Project would implement the SWIP SP land use plan and the Project’s proposed land use and development
intensity is consistent with the development regulations contained within the SWIP. Therefore, the GHG emissions
produced by the Project are within the scope of the project that was evaluated in the SWIP SP PEIR. Of note, the
proposed trailer yard would generate fewer daily traffic trips than the land uses assumed by the SWIP SP PEIR (the
Project’s daily traffic is discussed in further detail in EIR Addendum Subsection 4.17); therefore, the Project would
reduce vehicle tailpipe emissions within the SWIP SP area relative to the levels disclosed in the SWIP SP PEIR
(vehicle tailpipe emissions represent a substantial share of GHG emissions). Additionally, Senate Bill 32 (SB 32),
which was not in effect at the time the SWIP SP EIR was certified, establishes a more stringent GHG reduction
target than the regulations that were in effect at the time (i.e., Assembly Bill 32 [AB 32]). The Project would have
to comply with these more stringent GHG reduction targets, as well as other regulations that have been enacted
since 2012 that are more protective of the environment and will reduce the Project’s GHG emissions when
compared to the emissions levels the SWIP SP PEIR assumed would occur from the development of the Project
Site, including but not limited to the following: 1) 2022 California Energy Code (which is more stringent and
requires greater energy savings than the 2010 edition that was in effect at the time the SWIP SP PEIR was certified);
2) 2022 California Green Building Standards Code (which is more stringent and requires greater energy savings
than the 2010 edition that was in effect at the time the SWIP SP PEIR was certified); and 3) City of Fontana
Ordinance 1891 (Industrial Commerce Centers Sustainability Guidelines, which was not in effect at the time the
SWIP SP PEIR was certified and includes numerous design and operational measures that would directly reduce
local air pollution and GHG emissions and minimize potential adverse effects to global climate change).
Accordingly, the Project’s GHG emissions do not represent a new, significant air quality impact or an increase in
the severity of a significant air quality impact previously disclosed in the SWIP SP PEIR.
Additionally, the Project’s Greenhouse Gas Analysis report demonstrates that the Project would be consistent
with and would not conflict with implementation of the goals and objectives established by applicable GHG
emissions reductions plans, and policies, including AB 32, SB 32, and the CARB Scoping Plan. Refer to Appendix A
for a detailed analysis of the Project’s consistency with the consistency GHG emissions reductions plans and
policies. Lastly, the Project would be required to comply with MM 4.2-5a from the SWIP SP PEIR, which would
reduce the Project’s GHG emissions below the levels listed in Table 4-7 (and further reduce GHG emissions below
the levels disclosed by the SWIP SP PEIR).
Addendum to the
SWIP Specific Plan Update and Annexation PEIR Environmental Analysis
Almond Avenue Trailer Yard 4-33
Based on the foregoing analysis, the Project’s GHG emissions would be less than significant and would be further
reduced by after the application of required mitigation from the SWIP SP PEIR. Implementation of the Project
would not result in any new or more severe significant impacts related to conflicts with goals and objectives
established by applicable GHG emissions reductions plans, and policies than previously disclosed in the SWIP SP
PEIR.
Mitigation: No new or updated MMs are required. SWIP SP PEIR MM 4.2-5a, as presented previously in Subsection
4.6 applies to the Project.
4.9 Hazards and Hazardous Materials
A Phase I Environmental Site Assessment (ESA) dated March 10, 2025 (HMC, 2025a) and a Phase II ESA dated
November 11, 2025 (HMC, 2025b) was prepared by HMC Management Consulting, Inc. (HMC) to determine the
presence/absence of hazards and hazardous materials on the Project Site. This report is included as Appendix G
and Appendix H, respectively, to this EIR Addendum and its findings are incorporated in the analysis presented
herein.
Would the Project:
a. Create a significant hazard to the public or the environment through the routine transport, use, or disposal
of hazardous materials?
SWIP SP PEIR Finding: The SWIP SP PEIR determined that the land uses proposed by the SWIP SP could entail the
routine transport, use, storage, and/or disposal of hazardous materials. The SWIP SP PEIR disclosed that all future
development within the SWIP SP would be required to comply with applicable federal, state, and local regulations
related to handling, transport, and disposal of hazardous materials and waste. Additionally, the SWIP SP PEIR
established mitigation that prohibits the siting of facilities that handle hazardous materials near sensitive
receptors (i.e., schools, childcare facilities, and senior centers) and requires businesses that handle hazardous
materials to submit hazardous materials inventories to the San Bernardino County Fire Department (MM 4.5-1a
and 4.5-1c, respectively). The SWIP SP PEIR concluded that mandatory compliance with applicable regulations and
implementation of the MMs included in the SWIP SP PEIR would ensure that the SWIP SP would not create a
significant hazard to the public or the environment through the routine transport, use, or disposal of hazardous
materials. Impacts would be less than significant.
Analysis of Project: As demonstrated by the analysis below, the Project would not result in a hazard to the public
or the environment through the routine transport, use, or disposal of hazardous materials. The Project would not
result in any new impacts, or increase the severity of previously identified significant impacts, as compared to the
analysis presented in the SWIP SP PEIR.
Existing Conditions
A Phase I Environmental Site Assessment (ESA) was prepared for the Project Site to identify recognized
environmental conditions (RECs). The Site is currently used for outdoor storage of precast concrete products and
equipment, and the Phase I reconnaissance did not observe hazardous materials storage, USTs/ASTs, or other
Addendum to the
SWIP Specific Plan Update and Annexation PEIR Environmental Analysis
Almond Avenue Trailer Yard 4-34
hazardous material handling features associated with routine use of hazardous materials (HMC, 2025a, p. 11).
While the Phase I ESA identified the former gravel pit and uncontrolled fill as a REC and noted potential for
methane gas and vapor intrusion, these conditions relate to potential subsurface issues rather than routine
transport, use, or disposal of hazardous materials associated with current Site operations (HMC, 2025a, pp. 19-
22). The Phase I ESA review of regulatory databases did not identify any hazardous materials violations or cleanup
actions associated with the Project Site.
Although no evidence of hazardous materials/conditions were observed on the Project Site, the Project Applicant
would be required to comply with SWIP SP PEIR MM 4.5-2b, which requires the excavation/removal, remediation,
and off-site transport and disposal of hazardous materials in accordance with applicable federal, State, and local
requirements, should any contamination be discovered on the Project Site during construction. Compliance with
SWIP SP PEIR MM 4.5-2b would ensure that any potentially hazardous materials that may be present on the
Project Site under existing conditions would not present a substantial hazard to people or the environment.
Based on the foregoing analysis, the Project would not result in any new impacts, or increase the severity of
previously identified significant impacts, as compared to the analysis presented in the SWIP SP PEIR.
Construction Activities
Construction of the trailer yard (grading, paving, installation of striping, prefabricated office, and a guard shack)
would require use of heavy equipment fueled and maintained with oil, diesel, gasoline, and similar materials.
These substances are typical for all construction sites and would be used in small quantities subject to standard
regulatory requirements. Construction contractors would be required to comply with all applicable federal, state,
and local laws and regulations regarding the transport, use, and storage of hazardous construction-related
materials, including but not limited requirements imposed by the Environmental Protection Agency (EPA),
California Department of Toxic Substances Control (DTSC), SCAQMD, Santa Ana RWQCB, and the San Bernardino
County Fire Protection District. With mandatory compliance with applicable hazardous materials regulations, the
Project would not create a significant hazard to the public or the environment through routine transport, use, or
disposal of hazardous materials during the construction phase. The Project would not result in any new impacts,
or increase the severity of previously identified significant impacts, as compared to the analysis presented in the
SWIP SP PEIR.
Operational Activities
The Project involves a trailer storage yard, a small, prefabricated office, and a guard shack. Routine operations
would not involve the use, storage, or disposal of hazardous materials beyond small quantities of typical
commercial/maintenance supplies (e.g., cleaning products, lubricants, and paints). The Project does not propose
industrial uses, bulk chemical storage, vehicle fueling, or other hazardous materials operations. If any future
tenant or site operator uses hazardous materials in reportable quantities, they would be required to comply with
SWIP SP PEIR MM 4.5-1c, the California Hazardous Materials Release Response Plans and Inventory Law, the
Hazardous Materials Business Emergency Plan (HMBEP) requirements, and San Bernardino County Fire Protection
District permitting requirements. Mandatory regulatory compliance would ensure any hazardous materials, if
used, would not pose a significant hazard to the public or environment.
Addendum to the
SWIP Specific Plan Update and Annexation PEIR Environmental Analysis
Almond Avenue Trailer Yard 4-35
Compared to the land uses and assumptions analyzed in the SWIP SP PEIR, the Project represents a substantially
lower-intensity land use with respect to hazardous materials and would not increase the severity of previously
disclosed impacts.
Mitigation: No new or updated MMs are required. All applicable MMs identified in the SWIP SP PEIR to reduce
hazards and hazardous materials impacts continue to apply to the Project, as presented below and in the MMRP
for the SWIP SP PEIR, attached hereto as Appendix A.
MM 4.5-1c The City shall require all businesses that handle hazardous materials above the reportable
quantity to submit an inventory of the hazardous materials that they manage to the San
Bernardino County Fire Department – Hazardous Materials Division in coordination with the
Fontana Fire Protection District.
MM 4.5-2b Prior to potential remedial evacuation and grading activities within the site (if remediation is
required), impacted areas shall be cleared of all maintenance equipment and materials (e.g.,
solvents, grease, waste-oil), construction materials, miscellaneous stockpiled debris (e.g., scrap
metal, pallets, storage bins, construction parts), above ground storage tanks, surface trash, piping,
excess vegetation and other deleterious materials. These materials shall be removed off-site and
properly disposed of at an approved disposal facility. Once removed, a visual inspection of the
areas beneath the removed materials shall be performed. Any stained soils observed underneath
the removed materials shall be sampled. In the event concentrations of materials are detected
above regulatory cleanup levels during demolition or construction activities, the project applicant
shall comply with the following MMs in accordance with Federal, State, and local requirements:
• Excavation and disposal at a permitted, off-site facility;
• On-site remediation, if necessary, or
• Other MMs as deemed appropriate by the County.
MM 4.5-2c Prior to the issuance of a grading or building permit, a Certified Environmental Professional shall
confirm the presence or absence of asbestos-containing materials (ACMs) and lead-based paint
(LBPs) prior to structural demolition/renovation activities. Should ACMs or LBPs be present,
demolition materials containing ACMs and/or LBPs shall be removed and disposed of at an
appropriate permitted facility.
MM 4.5-2d In the event any electrical transformers require relocation as a result of future development
associated with the project, the relocation shall be conducted under the purview of the local
electricity purveyor to identify property-handling procedures regarding potential polychlorinated
biphenyls (PCBs).
Note: The following SWIP SP PEIR MMs do not apply to the Project or have been satisfied as part of the City’s
review of the Project’s proposed entitlement applications: MMs 4.5-1a, 4.5-1b, 4.5-1d were addressed during City
review; MM 4.5-2a was addressed by the Phase I Environmental Site Assessment that was prepared for the Project
(Appendix G); MMs 4.5-2e and 4.5-2f are not applicable to the Project due to the Project Site’s location.

b. Create a significant hazard to the public or the environment through reasonably foreseeable upset and
accident conditions involving the release of hazardous materials into the environment?
SWIP SP PEIR Finding:
Short-Term Construction Activities
The SWIP SP PEIR determined that the existing structures within the SWIP SP area likely contain LBP, ACMs, and/or
other contaminants, and therefore demolition of the buildings would potentially create a significant hazard to the
public or the environment through reasonably foreseeable upset and accident conditions involving the release of
hazardous materials into the environment, which presents a potentially significant impact. The SWIP SP PEIR
concluded that compliance with SWIP SP PEIR MM 4.5-2c requiring an ACM/LBP survey and any necessary
abatement be conducted prior to issuance of grading and/or building permits, as well as compliance with SCAQMD
Rule 1403, would reduce potential impacts associated with demolition to the existing buildings to a less-than-
significant level.
The SWIP SP PEIR also determined that grading and excavation for future development within the SWIP SP area
could expose construction workers and the public to unidentified hazardous substances present in the soil or
groundwater associated with the I-10 freeway, Union Pacific Railroad alignment, and unidentified underground
storage tanks (USTs). The SWIP SP PEIR included MMs to ensure that future development projects evaluate
potential, site-specific hazardous conditions and implement remediation programs, as needed, to ensure that
development activities within the SWIP SP area would not increase the potential for accident conditions that could
result in the release of hazardous materials into the environment (i.e., MM 4.5-2a, 4.5-2b, 4.5-2d-4.5-2f). The
SWIP SP PEIR concluded that compliance with the required MMs and applicable regulatory requirements would
reduce potential construction-related impacts to a level below significance.
Long-Term Operational Activities
The SWIP SP PEIR determined that the operation of future development associated with the SWIP SP could create
a significant hazard to the public or the environment through reasonably foreseeable upset and accident
conditions involving the release of hazardous materials into the environment. The SWIP SP PEIR disclosed that
typical incidents associated with operations of typical commercial and industrial development projects that could
result in accidental release of hazardous materials include leaking storage tanks, spills during transport,
inappropriate storage, inappropriate use, and/or natural disasters. The SWIP SP PEIR concluded that compliance
with mandatory regulations and SWIP SP PEIR MM 4.5-1a through 4.5-1d, which prohibit the siting of facilities
that handle hazardous materials near sensitive receptors (i.e., schools, childcare facilities and senior centers) and
the transportation of hazardous materials near sensitive receptors, and requires businesses that handle hazardous
materials to submit hazardous materials inventories to the San Bernardino County Fire Department would ensure
that operational impacts are less than significant.
Analysis of Project:
Short-Term Construction Activities
As described above, the Phase I ESA prepared for the Project Site did not identify any recognized environmental
conditions (RECs) on the Almond parcel. The Site contains no existing buildings that would require demolition, and
Addendum to the
SWIP Specific Plan Update and Annexation PEIR Environmental Analysis
Almond Avenue Trailer Yard 4-37
therefore the potential for upset or accidental release of hazardous materials associated with asbestos-containing
materials (ACMs) or lead-based paint (LBP) during demolition does not apply to this Project. Construction of the
trailer yard would involve typical grading, paving, and installation of a prefabricated office building and security
kiosk. As with any construction site, the use of heavy equipment would require fuels, oils, lubricants, and other
common construction-related materials that could be hazardous if improperly stored or handled. However,
construction contractors are required to comply with all applicable federal, State, and local regulations governing
the transportation, storage, and handling of hazardous materials.
Consistent with SWIP SP PEIR MM 4.5-2b, if previously unknown contamination (e.g., stained soil or odorous soil)
is encountered during grading, work must stop and appropriate sampling, handling, and off-site disposal
procedures must be implemented. Compliance with this MM ensures that any accidental discovery of hazardous
materials during construction would not result in a substantial hazard to workers or the public.
With mandatory regulatory compliance and implementation of applicable SWIP SP PEIR MMs, short-term
construction activities would not create a significant hazard through reasonably foreseeable upset or accident
conditions.
Long-Term Operational Activities
The Project includes a trailer storage yard, a small prefabricated office, a guard shack, and does not propose
industrial processes, fueling operations, bulk chemical storage, or other uses that typically involve hazardous
materials. Routine operation of the site would involve only small quantities of common commercial materials
(e.g., cleaning supplies), which do not pose a risk of significant accidental release. In the event that a future site
occupant or operator uses hazardous materials in reportable quantities, compliance with federal and State
Community Right-To-Know laws, the Hazardous Materials Business Emergency Plan (HMBEP) requirements, and
SWIP SP PEIR MM 4.5-1c would ensure proper storage, inventory reporting, spill response, and emergency
procedures. These regulations are designed to prevent or minimize accidental release of hazardous materials.
Given the nature of the proposed trailer yard and the lack of industrial operations, the Project would not materially
increase the potential for upset or accident conditions resulting in the release of hazardous materials. The SWIP
SP PEIR assumed more intensive industrial and warehouse uses within the Specific Plan area than what is proposed
for this Site; therefore, the Project would not result in new or more severe impacts.
Mitigation: No new or updated MMs are required. All applicable MMs identified in the SWIP SP PEIR to mitigate
hazards and hazardous materials impacts continue to apply to the Project, as listed above. Refer to the MMRP for
the SWIP SP PEIR, attached hereto as Appendix A.
Note: The following SWIP SP PEIR MMs do not apply to the Project or have been satisfied as part of the City’s
review of the Project’s proposed entitlement applications: MMs 4.5-1a, 4.5-1b, 4.5-1d were addressed during City
review; MM 4.5-2a was addressed by the Phase I Environmental Site Assessment prepared for the Project
(Appendix G); MMs 4.5-2e and 4.5-2f are not applicable to the Project due to the Project Site’s location.

SWIP Specific Plan Update and Annexation PEIR Environmental Analysis
Almond Avenue Trailer Yard 4-38
c. Emit hazardous emissions or handle hazardous or acutely hazardous materials, substances, or waste
within one-quarter mile of an existing or proposed school?
SWIP SP PEIR Finding: The SWIP SP PEIR disclosed that there are four (4) schools located either inside or within
one-quarter mile of the SWIP SP boundaries and that hazardous emissions or the handling of hazardous materials
or substances would occur within one-quarter mile of an existing or proposed school. The SWIP SP PEIR concluded
that compliance with standard regulatory requirements and MMs from the SWIP SP PEIR would ensure that
impacts associated with construction and operation of the SWIP SP are less than significant.
Analysis of Project: No existing or proposed schools are located within one-quarter mile of the Project Site.
Construction activities would involve only typical construction materials (e.g., fuels, lubricants, paints) used in
accordance with applicable federal, State, and local regulations. Project operations involve a trailer storage yard
with a small, prefabricated office and guard shack and would not emit hazardous emissions or involve the handling
of hazardous or acutely hazardous materials. Since there are no schools within one-quarter mile of the Site and
the Project does not involve hazardous material use, the Project would not expose a school to hazardous emissions
or hazardous material handling. Implementation of the Project would not result in any new impacts or more
severe significant impacts related to hazardous materials than previously disclosed in the SWIP SP PEIR.
d. Be located on a site which is included on a list of hazardous materials sites compiled pursuant to
Government Code Section 65962.5 and, as a result, would it create a significant hazard to the public or the
environment?
SWIP SP PEIR Finding: The SWIP SP PEIR disclosed that there are various hazardous material sites listed on federal,
State, and local records databases located within the SWIP SP area. As previously discussed under the analysis for
Items “a” and “b,” above, the SWIP SP PEIR included mitigation that requires future development projects within
the SWIP SP area to conduct site-specific investigations (i.e., Phase I ESAs) and perform remedial activities, as
necessary, prior to construction to correct any identified environmental conditions (SWIP SP PEIR MM 4.5-2a and
4.5-2b, respectively). The SWIP SP PEIR concluded that with the required mitigation, impacts would be reduced to
a level below significance.
Analysis of Project: Government Code Section 65962.5 (the “Cortese List”) identifies properties in the State of
California that are known to contain hazardous materials or have experienced a release that requires regulatory
action. According to the Phase I Environmental Site Assessment prepared for the Project, the Project Site is not
listed on any database compiled pursuant to Government Code Section 65962.5, including the DTSC hazardous
waste facilities list, the State Water Resources Control Board’s list of leaking underground storage tanks, or the
list of solid waste disposal or cleanup sites. The Project Site appeared in a limited number of environmental
databases due to routine regulatory permits (e.g., stormwater compliance), but these listings do not indicate
contamination, unauthorized releases, or regulatory cleanup requirements. No hazardous materials sites subject
to the Cortese List were identified on the Project Site. Since the Site is not included on any list of hazardous
materials sites pursuant to Government Code Section 65962.5, implementation of the Project would not create a
significant hazard to the public or the environment. Implementation of the Project would not result in any new
impacts or more severe significant impacts related to hazardous materials than previously disclosed in the SWIP
SP PEIR.

e. For a project located within an airport land use plan or, where such a plan has not been adopted, within
two miles of a public airport or public use airport, would the project result in a safety hazard or excessive
noise for people residing or working in the project area?
SWIP SP PEIR Finding: The SWIP SP PEIR disclosed that the Ontario International Airport is located approximately
three miles west of the SWIP SP Area and that the southwestern portion of the SWIP SP area is located within the
Ontario Airport’s “Airport Influence Area.” The SWIP SP PEIR determined that development within the SWIP SP
area would consist of industrial, commercial, and office development and would not result in a safety hazard for
people working in the SWIP SP area. Accordingly, the SWIP SP PEIR concluded that a less-than-significant impact
would occur.
Analysis of Project: The Project Site is located within the “Airport Influence Area” (AIA) for the Ontario
International Airport. The Project Site is not located within any airport safety zones, and the height of the proposed
structures would be consistent with applicable airspace protection requirements. The Project Site is located within
an area subject to aircraft noise exposure in the 60–65 dBA CNEL range. (City of Ontario, 2011) Industrial and
warehousing uses are considered compatible with this level of aircraft noise exposure, and the project-specific
noise analysis demonstrates that aircraft-related noise impacts would be less than significant. Accordingly, the
Project would neither introduce a hazard to airport operations nor expose future on-site employees to excessive
aircraft noise, and would not result in new or more severe significant impacts related to air travel than those
previously disclosed in the SWIP SP PEIR
f. Impair implementation of or physically interfere with an adopted emergency response plan or emergency
evacuation plan?
SWIP SP PEIR Finding: The SWIP SP PEIR disclosed that construction activities associated with future development
could temporarily impact traffic on streets that would serve as evacuation routes due to roadway improvements
and extension of construction activities into the rights-of-way. The SWIP SP PEIR included MMs 4.5-6a and 4.5-6b,
which require the implementation of a traffic control plan during construction of future development projects
within the SWIP SP area and, also, require coordination between the City of Fontana Engineering Department and
City of Fontana Police Department to ensure adequate access for emergency vehicles during the construction of
future development projects within the SWIP SP area. Additionally, the SWIP SP PEIR disclosed that all future
development would be required to provide sufficient emergency access, as required by the City’s Zoning Code.
The SWIP SP PEIR concluded that with implementation of the recommended mitigation, future construction
activities related to the SWIP SP would result in less-than-significant impacts with regard to emergency access.
Analysis of Project: The Project Site does not have any emergency facilities nor is it identified as an emergency
evacuation route by any emergency response plans or emergency evacuation plans (City of Fontana, 2018a).
During construction and at Project build out, adequate emergency vehicle access along Almond Avenue would be
required to be always maintained. As part of the City’s discretionary review process, the City reviewed the
Project’s plans and found that appropriate emergency ingress and egress is available to and from the Project Site
to ensure public safety; thus, the Project’s design would not substantially impede emergency response times in
the local area. Furthermore, the Project would be required to ensure adequate access for emergency vehicles is
maintained throughout the Project’s construction activities pursuant to SWIP SP PEIR MM 4.5-6a. Mandatory
compliance with SWIP SP PEIR MM 4.5-6a would ensure the Project’s impacts regarding interference with the
Addendum to the
SWIP Specific Plan Update and Annexation PEIR Environmental Analysis
Almond Avenue Trailer Yard 4-40
City’s emergency response plan and evacuation routes would be less than significant. Implementation of the
Project would not result in any new impacts or more severe impacts related to emergency response plans than
previously disclosed in the SWIP SP PEIR.
Mitigation: No new or updated MMs are required. All applicable MMs identified in the SWIP SP PEIR to mitigate
hazards and hazardous materials impacts – as presented below – continue to apply to the Project. Refer to the
MMRP for the SWIP SP PEIR, attached hereto as Appendix A.
MM 4.5-6a Prior to the issuance of grading permits, future developers shall prepare a Traffic Control Plan for
implementation during the construction phase. The Plan may include the following provisions,
among others:
• At least one unobstructed lane shall be maintained in both directions on surrounding
roadways.
• At any time only a single lane is available, the developer shall provide a temporary traffic
signal, signal carriers (i.e., flagpersons), or other appropriate traffic controls to allow travel in
both directions.
• If construction activities require the complete closure of a roadway segment, the developer
shall provide appropriate signage indicating detours/alternative routes.
MM 4.5-6b Prior to construction, the City of Fontana Engineering Department shall consult with the City of
Fontana Police Department to disclose temporary closures and alternative travel routes, in order
to ensure adequate access for emergency vehicles when construction of future projects would
result in temporary lane or roadway closures.
g. Expose people or structures, either directly or indirectly, to a significant risk of loss, injury or death involving
wildland fires?
SWIP SP PEIR Finding: The SWIP SP PEIR determined that the SWIP SP is in an urbanized area, and no wildlands
exist in the vicinity of the SWIP SP area. The SWIP SP PEIR concluded that no impact related to wildland hazards
would occur.
Analysis of Project: The Project Site is in an urbanized area and is not located adjacent to wildlands (Google Earth
Pro, 2025). The SWIP SP PEIR assumed the Project Site would be fully developed. Therefore, the Project would not
expose people or structures, either directly or indirectly to a significant risk of loss, injury, or death involving
wildland fires. Implementation of the Project would not result in any new impacts or more severe significant
impacts related to wildland fires than previously disclosed in the SWIP SP PEIR.
4.10 Hydrology and Water Quality
A Preliminary Water Quality Management Plan (WQMP) (dated January 27, 2026) (Thienes, 2026a) and Hydrology
Study (dated March 25, 2026) (Thienes, 2026b) were prepared for the Project by Thienes Engineering, Inc. (herein
“Thienes”). The purpose of the Preliminary WQMP is to help identify pollutants of concern, establish the BMP for
the Project to minimize the release of pollutants of concern, and establish long term maintenance responsibilities
Addendum to the
SWIP Specific Plan Update and Annexation PEIR Environmental Analysis
Almond Avenue Trailer Yard 4-41
for the Project’s water quality features. The Hydrology Report identifies drainage patterns and off-site flow
tributary to the Project Site and evaluates post-development runoff conditions. The hydraulic calculations are
intended to be used to design the Project’s storm drain system. These reports are included as Appendices I and J,
respectively, to this EIR Addendum and their findings are incorporated into the analysis presented herein.
Would the Project:
a. Violate any water quality standards or waste discharge requirements or otherwise substantially degrade
surface or ground water quality?
SWIP SP PEIR Finding: The SWIP SP PEIR determined that development of the SWIP SP could adversely affect
water quality through the discharge of various waterborne pollutants. The SWIP SP PEIR concluded that future
development projects within the SWIP SP would be required to comply with National Pollutant Discharge
Elimination System (NPDES) regulations and implement Best Management Practices (BMPs) to reduce water
pollution from urban runoff. The SWIP SP PEIR concluded that with adherence to existing State water quality
requirements, impacts to water quality would be less than significant.
Analysis of Project: As demonstrated in the analysis below, the Project would not violate any water quality
standards or waste discharge requirements. The Project would not result in any significant impacts that were not
disclosed in the SWIP SP PEIR or increase the severity of any significant impacts identified in the SWIP SP PEIR.
Construction Activities
Construction of the Project would involve clearing and demolition, grading, paving, utility installation, and
landscaping activities. Construction activities would result in the generation of potential water quality pollutants
such as silt, debris, and construction chemicals (such as paints and solvents), and other chemicals with the
potential to adversely affect water quality (should these materials come into contact with water that reaches the
groundwater table or flows off-site).
Pursuant to the requirements of the Santa Ana RWQCB and Fontana Municipal Code Section 5-14 (Compliance
with the NPDES Permit) & Chapter 23, Article IX (Preventing Discharge of Pollutants into Storm Drains), the Project
Applicant would be required to obtain coverage under the State’s General Construction Storm Water Permit for
construction activities (NPDES permit). The NPDES permit is required for all development projects that include
construction activities, such as clearing, grading, and/or excavation, that disturb at least one (1) acre of total land
area. In addition, the Project Applicant would be required to comply with the Santa Ana RWQCB’s Santa Ana River
Basin Water Quality Control Program. Compliance with the NPDES permit and the Santa Ana River Basin Water
Quality Control Program involves the preparation and implementation of a SWPPP for construction-related
activities. The SWPPP will specify the BMPs that the Project’s construction contractors would be required to
implement during construction activities to ensure that potential pollutants of concern are prevented, minimized,
and/or otherwise appropriately treated prior to being discharged from the subject property. Examples of BMPs
that may be utilized during construction include, but are not limited to sandbag barriers, geotextiles, storm drain
inlet protection, sediment traps, rip rap soil stabilizers, and hydro-seeding. Mandatory compliance with the
SWPPP would ensure that the Project does not violate any water quality standards or waste discharge
requirements during construction activities.
Addendum to the
SWIP Specific Plan Update and Annexation PEIR Environmental Analysis
Almond Avenue Trailer Yard 4-42
Operational Activities
To meet the requirements of the City’s Municipal Storm Water Permit – and in accordance with Fontana Municipal
Code Chapter 23, Article IX – the Project Applicant would be required to prepare and implement a WQMP. A
WQMP is a site-specific post-construction water quality management program designed to minimize the release
of potential waterborne pollutants, including pollutants of concern for downstream receiving waters, under long-
term conditions via BMPs. Implementation of the WQMP ensures on-going, long-term protection of the
watershed basin. The Project’s Preliminary WQMP, prepared by Thienes Engineering, Inc. is included as Appendix
I to this EIR Addendum. As identified in the Preliminary WQMP, the Project is designed to include structural source
control BMPs consisting of a hydrodynamic separator, underground detention system, and proprietary Modular
Wetlands System (MWS) for biotreatment (Thienes, 2026a, pp. 1-1 through 1-2). Non-structural source control
BMPs include routine catch basin inspection, litter and debris control, employee training, and compliance with
spill prevention and hazardous materials management requirements. Because infiltration is infeasible due to the
presence of uncontrolled fill soils, the on-site biotreatment BMPs are designed to treat the full design capture
volume prior to discharge. Treated flows and overflows would be discharged by daylighting onto a riprap pad at
the southwest corner of the Site, where runoff would disperse in a manner consistent with existing drainage
patterns.
Additionally, the NPDES program requires certain land uses, including certain industrial land uses, to prepare a
SWPPP for operational activities and to implement a long-term water quality sampling and monitoring program,
unless an exemption has been granted (Industrial General Permit). Under this currently effective NPDES Industrial
General Permit, the Project may be required to prepare a SWPPP for operational activities and implement a long-
term water quality sampling and monitoring program or receive an exemption. Because the permit is dependent
upon a detailed accounting of all operational activities and procedures, and the Project’s users and their
operational characteristics are not currently known, details of the operational SWPPP (including BMPs) or
potential exemption to the SWPPP operational activities requirement cannot be determined with certainty at this
time. However, based on the performance requirements of the NPDES Industrial General Permit, the Project’s
mandatory compliance with all applicable water quality regulations would further reduce potential water quality
impacts during long-term operation.
Based on the foregoing analysis, the Project would not violate any water quality standards or waste discharge
requirements or otherwise substantially degrade surface or ground water quality during long-term operation.
Implementation of the Project would not result in any new or more severe significant impacts related to water
quality than previously disclosed in the SWIP SP PEIR.
b. Substantially decrease groundwater supplies or interfere substantially with groundwater recharge such
that the project may impede sustainable groundwater management of the basin?
SWIP SP PEIR Finding: The SWIP SP PEIR determined that the majority of the SWIP SP area is developed and
urbanized and, therefore, that implementation of the SWIP SP would not introduce substantial new impervious
surfaces to the SWIP SP area. The SWIP SP PEIR also disclosed that no groundwater extraction would occur as part
of the SWIP SP. Accordingly, the SWIP SP PEIR concluded that implementation of the SWIP SP would result in less-
than-significant impacts related to depletion of groundwater supplies or interference with groundwater recharge.
Addendum to the
SWIP Specific Plan Update and Annexation PEIR Environmental Analysis
Almond Avenue Trailer Yard 4-43
Analysis of Project: The Project would be required to connect to the City of Fontana’s municipal water system;
therefore, no water wells would be constructed on the Project Site and Project operations would not directly draw
groundwater supplies. The Project Site is underlain by the Chino Groundwater Basin. Most of the groundwater
recharge in the Chino Groundwater Basin occurs within percolation basins located mostly in the northern and
western portions of the Basin (and north and west of the City of Fontana) (CBWCD, 2017). Infiltration of on-site
runoff is infeasible due to underlying uncontrolled fill soils. Instead, the Project’s on-site storm drain system is
designed to capture, detain, and treat stormwater runoff through biotreatment and proprietary treatment control
BMPs prior to discharge. These design features would maintain existing drainage patterns and prevent substantial
alteration of groundwater recharge conditions. Accordingly, implementation of the Project would not
substantially decrease groundwater supplies or interfere with groundwater recharge and would not impede
sustainable groundwater management of the Chino Groundwater Basin. The Project would not result in any new
or more severe significant impacts related to groundwater supplies or recharge than previously disclosed in the
SWIP SP PEIR.
c. Substantially alter the existing drainage pattern of area, including through the alteration of the course of
a stream or river or through the addition of impervious surfaces, in a manner which would:
i. result in substantial erosion or siltation on- or off-site?
SWIP SP PEIR Finding: The SWIP SP PEIR disclosed that the SWIP SP area is located within an urbanized area that
is served by existing stormwater drainage facilities operated by the City of Fontana and the County of San
Bernardino. The SWIP SP PEIR concluded that the drainage infrastructure proposed by the SWIP SP would
adequately serve future development within the SWIP SP area and would minimize impacts related to erosion or
siltation, resulting in less-than-significant impacts regarding erosion or siltation.
Analysis of Project: As previously discussed under Response 4.7(b), implementation of the Project would not
result in substantial soil erosion or the loss of topsoil. Implementation of the Project would not result in any new
or more severe significant impacts related to soil erosion or siltation than previously disclosed in the SWIP SP PEIR.
ii. Substantially increase the rate or amount of surface run off in a manner which would result in
flooding on- or off-site?
SWIP SP PEIR Finding: The SWIP SP PEIR concluded that implementation of the SWIP SP would not result in a
substantial increase in surface runoff and would result in less-than-significant impacts related to flooding.
Analysis of Project: The Project would implement industrial land uses on the Project Site in accordance with the
SWIP SP land plan; therefore, the site development activities proposed by the Project (and the resulting surface
runoff flows) were planned by the SWIP SP (and its storm drain master plan) and anticipated by the SWIP SP PEIR,
which assumed the entire Project Site would be developed. According to the Project’s Preliminary Hydrology
Report, the existing-condition 25-year peak flow rate from the site is approximately 14.7 cubic feet per second
(cfs). The City’s design standard requires that the post-development 100-year peak discharge not exceed 90
percent of the existing 25-year peak flow, or approximately 13.2 cfs. The Project is designed to achieve a 100-year
peak discharge of approximately 12.7 cfs, which satisfies this criterion. (Thienes, 2026b, pp. 6-7) Accordingly, the
Project would not substantially increase the rate or amount of surface runoff in a manner that would result in
Addendum to the
SWIP Specific Plan Update and Annexation PEIR Environmental Analysis
Almond Avenue Trailer Yard 4-44
flooding on- or off-site. Implementation of the Project would not result in any new or more severe significant
impacts related to flooding on- or off-site than previously disclosed in the SWIP SP PEIR.
iii. Create or contribute runoff water which would exceed the capacity of existing or planned
stormwater drainage systems or provide substantial additional sources of polluted runoff?
SWIP SP PEIR Finding: The SWIP SP PEIR concluded that implementation of the SWIP SP would require the
installation of drainage infrastructure improvements; but that existing and planned stormwater drainage systems
would have adequate capacity to convey surface runoff flows from the SWIP SP area. The SWIP SP PEIR also
concluded that the SWIP SP would not generate substantial, additional sources of polluted runoff.
Analysis of Project: As discussed in Response 4.10(a) above, the Project will be required to comply with a SWPPP
and a site-specific WQMP, which will identify BMPs necessary to ensure that near-term construction activities and
long-term operations would not result in substantial amounts of polluted runoff. The Project proposes to
redevelop the Site with a trailer parking facility and associated improvements that would not substantially
increase impervious area compared to existing conditions. According to the Project’s Preliminary Hydrology
Report, the Project would not exceed the City’s allowable discharge threshold and would be designed to avoid
adverse effects on neighboring properties and downstream storm drain facilities. Additionally, the Project’s
WQMP includes structural and operational BMPs to minimize potential long-term water quality impacts. (Thienes,
2026a, pp. 1-1). Implementation of the Project would not result in any new or more severe significant impacts
related to existing or planned stormwater drainage systems or polluted runoff than previously disclosed in the
SWIP SP PEIR.
iv. Impede or redirect flood flow?
SWIP SP PEIR Finding: The SWIP SP PEIR concluded that although portions of the SWIP SP area would be located
within the 100-year base flood plain, the SWIP SP area is already developed with urbanized uses, and future
development of structures within the SWIP SP area would not occur within an existing floodway or otherwise
impede or redirect flood flows. Therefore, the SWIP SP PEIR concluded that the SWIP SP would result in a less-
than-significant impact.
Analysis of Project: According to Figure 4-1, Flood Hazard Map, of the City’s General Plan EIR, the Project Site and
surrounding area are not within a Federal Emergency Management Agency (FEMA) 100-year flood zone (City of
Fontana, 2018b). Accordingly, the Project would not place structures within a 100-year flood hazard area that
could impede or redirect flood flows, which the same area that the SWIP SP PEIR assumed would be developed
with structures. Implementation of the Project would not result in any new or more severe significant impacts
related to flood flows than previously disclosed in the SWIP SP PEIR.
d. In flood hazard, tsunami, or seiche zones, risk release of pollutants due to project inundation?
SWIP SP PEIR Finding: The SWIP SP PEIR determined that the SWIP SP area is not located near a major dam or
within a dam inundation area. Additionally, the SWIP SP PEIR did not identify any significant effects within the
SWIP SP area related to inundation by seiche, tsunami, or mudflow.
Addendum to the
SWIP Specific Plan Update and Annexation PEIR Environmental Analysis
Almond Avenue Trailer Yard 4-45
Analysis of Project: The Pacific Ocean is located over 40 miles southwest of the Project Site; consequently, there
is no potential for the Project Site to be impacted by a tsunami as tsunamis typically only reach up to a few miles
inland. The Project Site is not subject to flooding hazards associated with a seiche as the nearest large body of
surface water (Prado Reservoir) is located approximately 12 miles southwest of the Project Site, which is too far
away to inundate the Project Site. Furthermore, as noted in the City of Fontana General Plan EIR on Figure 4-2,
Dam Inundation Areas in Fontana, the Project Site is not located within any mapped dam inundation area, which
the same area that the SWIP SP PEIR assumed would be developed with structures (City of Fontana, 2018b).
Implementation of the Project would not result in any new or more severe significant impacts related to
inundation than previously disclosed in the SWIP SP PEIR.
e. Conflict with or obstruct implementation of water quality control plan or sustainable groundwater
management plan?
SWIP SP PEIR Finding: The SWIP SP PEIR concluded that future development within the SWIP SP area would be
required to adhere to State water quality requirements and would not result in substantial adverse water quality
effects. Although the SWIP SP PEIR did not specifically address the potential for the SWIP SP PEIR to conflict with
or obstruct implementation of a sustainable groundwater management plan, the PEIR did address the potential
for the SWIP SP to deplete groundwater supplies or interfere with groundwater recharge (and concluded that
such impacts would be less than significant).
Analysis of Project: As discussed in Response 4.10(a) above, the Project Site is located within the Santa Ana River
Basin and Project-related construction and operational activities would be required to comply with the Santa Ana
RWQCB’s Santa Ana River Basin Water Quality Control Plan by preparing and adhering to a SWPPP and WQMP.
Implementation of the Project would not conflict with or obstruct the Santa Ana River Basin Water Quality Control
Plan.
The Project Site is located within the Chino Groundwater Basin, which is an adjudicated groundwater basin.
Adjudicated basins, like the Chino Groundwater Basin are exempt from the 2014 Sustainable Groundwater
Management Act (SGMA) because such basins already operate under a court-ordered management plan to ensure
the long-term sustainability of the Subbasin. The Project would include onsite stormwater detention and
controlled discharge to meet City peak flow requirements. Discharge would be limited using an orifice plate, and
temporary surface detention would occur in the southerly area around the proposed catch basins. (Thienes,
2026b, pp. 2-3) No component of the Project would obstruct or prevent implementation of the management plan
for the Chino Groundwater Basin. As such, the Project’s construction and operation would not conflict with any
sustainable groundwater management plan.
Based on the foregoing information, implementation of the Project would not result in any new or more severe
significant impacts related to the implementation of water quality control plans or sustainable groundwater
management plans than previously disclosed in the SWIP SP PEIR.

SWIP Specific Plan Update and Annexation PEIR Environmental Analysis
Almond Avenue Trailer Yard 4-46
4.11 Land Use and Planning
Would the Project:
a. Physically divide an established community?
SWIP SP PEIR Finding: The SWIP SP PEIR determined the SWIP SP would not divide an established community, as
it would implement a range of industrial, commercial, public, and residential land uses similar to the land uses
that already existed within the SWIP SP boundaries. Additionally, the SWIP SP PEIR determined that existing
development within the SWIP SP area was already divided by the existing local roadway network, and the SWIP
SP would not create additional physical barriers between these land uses. Therefore, the SWIP SP PEIR concluded
impacts in this regard would be less than significant.
Analysis of Project: The Project would implement the land use plan for the SWIP Specific Plan. While several legal
nonconforming single-family residences are located approximately 0.17 mile south, 0.20 mile west, and 0.27 mile
east of the Project Site, these residences are isolated and are separated from the Project Site by existing industrial
uses and public roadways. No component of the Project would interfere with access to or from these residences
from existing public streets or from existing points of ingress and egress. Thus, the Project would not divide an
established community, nor would the Project prevent or obstruct access to an established community.
Implementation of the Project would not result in any new or more severe significant impacts related to physically
dividing an established community than previously disclosed in the SWIP SP PEIR.
b. Cause a significant environmental impact due to a conflict with any land use plan, policy, or regulation
adopted for the purpose of avoiding or mitigating an environmental effect?
SWIP SP PEIR Finding: The SWIP SP PEIR determined that the SWIP SP would not directly conflict with the policy
or regulations adopted for the purpose of avoiding or mitigating an environmental effect, including the City’s
General Plan and Zoning and Development Code. Accordingly, the SWIP SP PEIR concluded that the SWIP SP would
result in a less-than-significant impact.
Analysis of Project: The Project Site would be developed in accordance with the land use regulations and
development standards contained within the SWIP SP; therefore, the development activities proposed by the
Project were anticipated by the SWIP SP PEIR, and in fact, the Project would implement the vision of the SWIP SP,
making the Project Site more much consistent with applicable land use policies, plans and regulations that existing
uses. As noted above, the SWIP SP PEIR concluded that implementation of the SWIP SP would not conflict with
any land use policies or regulations adopted for the purpose of mitigating or avoiding an environmental impact.
Thus, because the Project is consistent with the SWIP SP and because the SWIP SP was previously found to not
conflict with any land use plan, policy, or regulation adopted for the purpose of avoiding or mitigating an
environmental effect, implementation of the Project would not cause a significant environmental impact due to
a land use planning conflict. Implementation of the Project would not result in any new or more severe significant
impacts related to conflicts with a land use plan, policy, or regulation than previously disclosed in the SWIP SP
PEIR.

4.12 Mineral Resources
Would the Project:
a. Result in the loss of availability of a known mineral resource that would be of value to the region and the
residents of the state?
SWIP SP PEIR Finding: The SWIP SP PEIR determined that according to the City’s General Plan, no known deposits
of precious gemstones, ores, or unique, or rare minerals have been identified within the vicinity of the SWIP SP
area. Thus, no impact would occur in this regard.
Analysis of Project: The Project Site is located within the mineral resource zone 3 (MRZ-3), which is classified as
an area where the significance of mineral deposits cannot be determined from available data (DOC, 1984). As
such, the Project Site does not contain a “known mineral resource.” Additionally, the Project Site is not zoned for
mining and is not used for mining under existing conditions. The Project, which would develop an area that the
SWIP SP PEIR assumed would be developed with non-mining land uses, would not result in the loss of availability
of a known mineral resource that would be of value to the region and the residents of the State. Implementation
of the Project would not result in any new or more severe significant impacts related to mineral resources than
previously disclosed in the SWIP SP PEIR.
b. Result in the loss of availability of a locally-important mineral resource recovery site delineated on a local
general plan, specific plan or other land use plan?
SWIP SP PEIR Finding: The SWIP SP PEIR did not identify any significant environmental effects within the SWIP SP
area related to the loss of availability of a locally-important mineral resource recovery site delineated on a local
general plan, specific plan or other land use plan. The SWIP SP PEIR concluded that no impact would occur.
Analysis of Project: The Project Site is not located in an area that the City’s General Plan or the SWIP SP have
identified as being of local importance for mineral resources. Accordingly, implementation of the Project would
not result in the loss of availability of a locally-important mineral resource recovery site delineated on a local
general plan, specific plan, or other land use plan. Implementation of the Project would not result in any new
impacts or more severe impacts related to the loss of availability of a locally-important mineral resource recovery
site than previously disclosed in the SWIP SP PEIR.
4.13 Noise
A Noise Impact Analysis (dated March 4, 2025) (Urban Crossroads, 2025a) was prepared for the Project by Urban
Crossroads to evaluate Project-related long-term operational and short-term construction noise impacts. This
report is included as Appendix K to this EIR Addendum, and its findings are incorporated into the analysis
presented herein.
Would the Project result in:
Addendum to the
SWIP Specific Plan Update and Annexation PEIR Environmental Analysis
Almond Avenue Trailer Yard 4-48
a. Generation of a substantial temporary or permanent increase in ambient noise levels in the vicinity of the
project in excess of standards established in the local general plan or noise ordinance, or applicable
standards of other agencies?
SWIP SP PEIR Finding: The SWIP SP PEIR determined that although the construction of future development and
improvements in the SWIP SP Area would be required to adhere to the hours permitted by the City’s Municipal
Code (between 7:00 a.m. and 6:00 p.m. on weekdays and between 8:00 a.m. and 5:00 p.m. on Saturdays), due to
the proximity of residential and institutional uses to the SWIP SP area, such construction could result in temporary,
localized increases in noise levels and vibration that may exceed established standards. As such, the SWIP SP PEIR
included mitigation to minimize potential adverse effects to sensitive receptors (SWIP SP PEIR MMs 4.7-1a and
4.7-1b). The SWIP SP PEIR concluded that compliance with the City’s permitted hours of construction and
implementation of SWIP SP PEIR MMs 4.7-1a and 4.7-1b would ensure construction-related noise levels do not
exceed regulatory standards, and impacts would be less than significant.
The SWIP SP PEIR determined that future development in the SWIP SP area could, potentially, result in a
permanent exposure of sensitive receptors to ambient noise from stationary sources that exceeds established
standards. The SWIP SP PEIR included MM 4.7-2a, which requires industrial facilities in proximity to existing
sensitive receptor land uses to implement design MMs such as noise walls and berms to minimize operational
noise levels. Additionally, the SWIP SP includes design guidelines and development standards that are aimed at
reducing noise impacts, including building orientation, wall placement, lot dimensions, maximum intensity,
outdoor storage, setbacks, buffers, edge conditions, and landscaping that would serve to minimize noise impacts
on sensitive land uses in the vicinity. The SWIP SP PEIR concluded that with implementation of the SWIP SP design
guidelines and development standards and implementation of mitigation, the SWIP SP would result in less-than-
significant stationary source noise impacts.
The SWIP SP PEIR determined that future development in the SWIP SP area could result in a permanent increase
in ambient noise levels from mobile sources (vehicular traffic and rail) in excess of established standards. The
SWIP SP PEIR concluded that future mobile noise source impacts from buildout of the SWIP SP would be significant
and unavoidable.
Analysis of Project: The analysis below summarizes the potential for Project-related activities to generate or
expose sensitive receptors to noise levels that exceed applicable standards during temporary construction
activities and/or long-term operation. As demonstrated in the analysis below, implementation of the Project
would not result in any new or increase the severity of previously identified significant impacts, as compared to
the analysis presented in the SWIP SP PEIR. Refer to the Project’s Noise Impact Analysis (Appendix K) for a detailed
discussion of the methodologies and assumptions used to calculate the Project’s construction and operational
noise.
Construction Activities
Project construction would result in short-term noise associated with site preparation, grading, building
construction, paving, and architectural coatings. The Project would implement land uses that are consistent with
those contemplated under the SWIP SP land use plan; therefore, construction activities would be similar in nature,
intensity, and duration to those assumed in the SWIP SP PEIR. Construction noise levels at the nearest sensitive
receptors would range from approximately 50.4 to 57.1 dBA Leq, which would not exceed the applicable 80 dBA
Addendum to the
SWIP Specific Plan Update and Annexation PEIR Environmental Analysis
Almond Avenue Trailer Yard 4-49
Leq daytime construction noise threshold (Urban Crossroads, 2025a, p. 46). Temporary construction noise
increases above existing ambient conditions would range from 0.2 to 5.7 dBA Leq, well below the 20 dBA Leq
threshold considered a substantial temporary increase (Urban Crossroads, 2025a, p. 47).
The Project would be required to comply with the City’s standard conditions of approval to minimize construction
noise (provided at the end of this section for reference) and SWIP SP PEIR MMs 4.7-1a, which requires the Project’s
construction contractor to comply with the permitted daytime hours of construction as defined in Section 18-63
of the City’s Municipal Code and with defined performance criteria to minimize noise emissions from the Project
Site during construction. Compliance with applicable mitigation from the SWIP SP PEIR, required City conditions
of approval, and applicable standards from the City’s Municipal Code would ensure that implementation of the
Project would not result in any new or more severe impacts from construction noise than previously disclosed in
the SWIP SP PEIR.
Operational Activities – On-Site Noise
Long-term operational noise would result from on-site sources such as trailer storage activity, truck movements,
trash enclosure activity, and mechanical equipment. Project operational noise levels at nearby noise-sensitive
receptors would range from approximately 32.3 to 38.5 dBA Leq during both daytime and nighttime hours (Urban
Crossroads, 2025a, p. 39). These levels would not exceed the City’s applicable exterior stationary-source noise
standard of 65 dBA Leq for residential land uses. In addition, Project-related operational noise would increase
existing ambient noise levels by approximately 0.0 to 0.5 dBA Leq, which is well below the applicable operational
noise increase thresholds of significance (Urban Crossroads, 2025a, p. 41). Accordingly, operation of the Project
would not result in the generation of a substantial permanent increase in ambient noise levels in the vicinity of
the Project Site in excess of the standards from the City of Fontana’s Noise Ordinance. Implementation of the
Project would not result in any new or more severe significant impacts from on-site stationary operational noise
sources than previously disclosed in the SWIP SP PEIR.
Operational Noise – Off-Site Mobile Sources (Traffic)
The Project would implement the SWIP SP land use plan; therefore, the mobile-source noise emissions (i.e., traffic
noise) produced by the Project were anticipated by the SWIP SP PEIR. The Project’s proposed land uses would
generate fewer daily traffic trips than the land uses assumed by the SWIP SP PEIR (the Project’s daily traffic is
discussed in further detail in Subsection 4.17); therefore, the Project would reduce mobile-source noise emissions
within the SWIP SP area relative to the levels disclosed in the SWIP SP PEIR but the mobile-source noise reductions
afforded by the Project would not be sufficient to avoid the significant and unavoidable mobile-source noise
impact, as identified in the SWIP SP PEIR. Notwithstanding and based on the foregoing, the Project would not
result in any new or more severe significant impacts from mobile sources than the significant and unavoidable
impacts that were previously disclosed in the SWIP SP PEIR.
Standard Condition of Approval: The City requires the following condition of approval of all discretionary
development approvals:
The construction contractor will use the following source controls at all times:
Addendum to the
SWIP Specific Plan Update and Annexation PEIR Environmental Analysis
Almond Avenue Trailer Yard 4-50
a. Construction shall be limited to 7:00 am to 6:00 pm on weekdays, 8:00 am to 5:00 pm on
Saturdays, and no construction on Sundays and Holidays unless it is approved by the
building inspector for cases that are considered urgently necessary as defined in Section
18-63(7) of the Municipal Code.
b. For all noise-producing equipment, use types and models that have the lowest
horsepower and the lowest noise generating potential practical for their intended use.
c. The construction contractor will ensure that all construction equipment, fixed or mobile,
is properly operating (tuned-up) and lubricated, and that mufflers are working
adequately.
d. Have only necessary equipment onsite.
e. Use manually-adjustable or ambient-sensitive backup alarms. When working adjacent to
residential use(s), the construction contractor will also use the following path controls,
except where not physically feasible, when necessary:
i. Install portable noise barriers, including solid structures and noise blankets,
between the active noise sources and the nearest noise receivers.
ii. Temporarily enclose localized and stationary noise sources.
iii. Store and maintain equipment, building materials, and waste materials as far as
practical from as many sensitive receivers as practical.
Mitigation: No new or updated MMs are required. All applicable MMs identified in the SWIP SP PEIR to reduce
noise impacts continue to apply to the Project, as listed below and in the MMRP for the SWIP SP PEIR (attached
hereto as Appendix A).
MM 4.7-1a The following MMs shall be implemented when construction is to be conducted within 500 feet
of any sensitive structures or has the potential to disrupt classroom activities or religious
functions.
• The City shall restrict noise intensive construction activities to the days and hours specified
under Section 18-63 of the City of Fontana Municipal Code. These days and hours shall also
apply any servicing of equipment and to the delivery of materials to or from the site.
• All construction equipment shall be equipped with mufflers and sound control devices (e.g.,
intake silencers and noise shrouds) no less effective than those provided on the original
equipment and no equipment shall have an unmuffled exhaust.
• The City shall require that the contractor maintain and tune-up all construction equipment to
minimize noise emissions.
• Stationary equipment shall be placed so as to maintain the greatest possible distance to the
sensitive use structures.
• All equipment servicing shall be performed so as to maintain the greatest possible distance
to the sensitive use structures.
• If construction noise does prove to be detrimental to the learning environment, the City shall
allow for a temporary waiver thereby allowing construction on Weekends and/or holidays in
those areas where this construction is to be performed in excess of 500 feet from any
residential structures.
Addendum to the
SWIP Specific Plan Update and Annexation PEIR Environmental Analysis
Almond Avenue Trailer Yard 4-51
• The construction contractor shall provide an on-site name and telephone number of a contact
person. Construction hours, allowable workdays, and the phone number of the job
superintendent shall be clearly posted at all construction entrances to allow for surrounding
owners and residents to contact the job superintendent. If the City or the job superintendent
receives a complaint, the superintendent shall investigate, take appropriate corrective action,
and report the action taken to the reporting party. In the event that construction noise is
intrusive to an educational process, the construction liaison will revise the construction
schedule to preserve the learning environment.
MM 4.7-b Should potential future development facilitated by the proposed project require offsite
import/export of fill material during construction, trucks shall utilize a route that is least disruptive
to sensitive receptors, preferably major roadways (Interstate 10, Interstate 15, State Route 60,
Sierra Avenue, Beech Avenue, Jurupa Avenue, and Slover Avenue). Construction trucks should, to
the extent practical, avoid the weekday and Saturday a.m. and p.m. peak hours (7:00 a.m. to 9:00
a.m. and 4:00 p.m. to 6:00 p.m.).
Note: The following SWIP SP PEIR MMs do not apply to the Project or have been satisfied as part of the City’s
review of the Project’s proposed entitlement applications: MMs 4.7-2a and 4.7-3b were satisfied by the Project’s
Noise Analysis (Appendix K) prepared for the Project; MM 4.7-3a does not apply to the Project because the Project
is not a noise-sensitive land use and due to the location of the Project Site.
b. Generation of excessive ground borne vibration or ground borne noise levels?
SWIP SP PEIR Finding: The SWIP SP PEIR disclosed that construction activities associated with the SWIP SP could
potentially expose sensitive receptors to sporadic, high vibration levels. However, the SWIP SP PEIR concluded
that with implementation of SWIP SP PEIR MMs 4.7-1a and 4.7-1b (previously described under Threshold “a”), the
SWIP SP would generate less-than-significant ground borne vibration or ground borne noise during construction
activities.
Analysis of Project: Construction of the Project would involve typical site preparation, grading, and building
construction activities that are similar in nature to those anticipated under the SWIP SP PEIR. Project-specific
vibration modeling indicates that peak construction-related vibration levels at the nearest sensitive receptors
would be less than or equal to 0.01 inches per second (in/sec) peak particle velocity (PPV) (Urban Crossroads,
2025a, p. 48). These levels are well below the Caltrans Transportation and Construction Vibration Guidance
Manual threshold of 0.3 PPV (in/sec) for older residential structures. Accordingly, construction of the Project
would not generate excessive ground-borne vibration or ground-borne noise levels.
During Project operation, vibration levels associated with truck and trailer movements within the Project Site and
along adjacent public roadways would be similar to existing conditions, as truck activity currently occurs in the
vicinity of the Project Site. Operational vibration levels are not expected to result in perceptible or excessive
ground-borne vibration or ground-borne noise at nearby sensitive receptors. Implementation of the Project would
not result in any new or more severe ground-borne vibration or ground-borne noise impacts than those previously
disclosed in the SWIP SP PEIR.

c. For a project located within the vicinity of a private airstrip or an airport land use plan or, where such a
plan has not been adopted, within two miles of a public airport or public use airport, would the project
expose people residing or working in the project area to excessive noise levels?
SWIP SP PEIR Finding: The SWIP SP PEIR determined that people residing or working within the SWIP SP area
would not be exposed to excessive aircraft noise levels from operations at the Ontario International Airport
(located approximately 11 miles to the west of the SWIP SP area). Therefore, the SWIP SP PEIR concluded that a
less-than-significant impact would occur.
Analysis of Project: Ontario International Airport is located over four miles from the Project Site. Accordingly, the
SWIP SP PEIR concluded that aircraft noise impacts would be less than significant. The Project Site is not located
within the vicinity of a private airstrip or within two miles of a public or public-use airport. Implementation of the
Project would not increase exposure of people residing or working in the Project area to aircraft-related noise.
The Project would not result in any new or more severe impacts related to aircraft noise than those previously
disclosed in the SWIP SP PEIR.
4.14 Population and Housing
Would the Project:
a. Induce substantial unplanned population growth in an area, either directly (for example, by proposing new
homes and businesses) or indirectly (for example, through extension of roads or other infrastructure)?
SWIP SP PEIR Finding: The SWIP SP PEIR concluded that the SWIP SP would be a growth-inducing project due to
the following factors: development of infrastructure improvements that would provide additional capacity
necessary to support development within the SWIP SP area; the creation of 39,416 new employment positions
that would foster economic expansion and growth within the City of Fontana; and direct growth in the City’s
population due to the potential for future employees (and their families) to relocate to the City of Fontana.
Accordingly, the SWIP SP PEIR concluded the SWIP SP would result in a significant and unavoidable impact related
to growth inducement.
Analysis of Project: The Project does not include a residential component and, therefore, would not directly
induce population growth within the area. The Project would redevelop an existing industrial property with a
trailer parking facility and a small, prefabricated office building to support on-site operations. The Project would
not generate a substantial number of new employment opportunities or extend infrastructure beyond what has
already been planned and constructed to serve the SWIP SP area. The Project represents implementation of the
adopted SWIP SP, which designates the Site for industrial uses, and was anticipated in the SWIP SP PEIR.
Accordingly, the Project would not induce population growth to a greater degree than previously disclosed, and
no new or more severe impacts related to substantial unplanned population growth would occur beyond those
identified as significant and unavoidable in the SWIP SP PEIR.

SWIP Specific Plan Update and Annexation PEIR Environmental Analysis
Almond Avenue Trailer Yard 4-53
b. Displace substantial numbers of existing people or housing, necessitating the construction of replacement
housing elsewhere?
SWIP SP PEIR Finding: The SWIP SP PEIR determined the SWIP SP would not result in any direct impacts to existing
residences located within the SWIP SP area that would necessitate construction of replacement housing. The SWIP
SP PEIR concluded impacts in this regard would be less than significant.
Analysis of Project: There are no existing dwelling units on the Project Site, and no housing would be removed or
displaced as a result of the Project. Implementation of the Project would not displace any residents or necessitate
the construction of replacement housing elsewhere. The Project would not result in any new or more severe
impacts related to the displacement of people or housing than previously disclosed in the SWIP SP PEIR.
4.15 Public Services
Would the project result in substantial adverse physical impacts associated with the provision of new or physically
altered governmental facilities, need for new or physically altered governmental facilities, the construction of
which could cause significant environmental impacts, in order to maintain acceptable service ratios, response times
or other performance objectives for any of the public services:
a. Fire Protection?
SWIP SP PEIR Finding: The SWIP SP PEIR determined that future development associated with the SWIP SP would
increase the need for fire protection and emergency medical services within the SWIP SP area. However, all future
development projects located within the SWIP SP area would be required to pay the City’s development impact
fee and the SWIP SP PEIR included MMs 4.8-2a through 4.8-2c that established performance goals for the City to
monitor to ensure that acceptable fire protection resources, service ratios, and response times are met. The SWIP
SP PEIR concluded that with payment of development impact fees and implementation of the required mitigation,
the SWIP SP would result in less-than-significant impacts regarding fire protection services.
Analysis of Project: The Project Applicant would develop the Project Site in accordance with the SWIP SP land use
plan. Accordingly, the development activities proposed by the Project were planned by the SWIP SP and, thus, the
Project’s demand for fire protection services was anticipated by the SWIP SP PEIR. The Project Applicant would
also be required to pay applicable development impact fees, as specified in the SWIP SP PEIR, to offset its demand
for fire protection services. (The City uses a portion of collected development impact fees to fund fire protection
facilities.) Implementation of the Project would not result in any new impacts or more severe impacts related to
fire protection services than previously disclosed in the SWIP SP PEIR.
Mitigation: No new or updated MMs are required. SWIP SP PEIR MMs 4.8-2a through 4.8-2c, which address
impacts to fire protection services, are policy-level actions that fall under the City’s responsibility and do not
require any actions from private development projects. No component of the Project would prevent or obstruct
the City’s implementation of SWIP SP PEIR MMs 4.8-2a through 4.8-2c.
Addendum to the
SWIP Specific Plan Update and Annexation PEIR Environmental Analysis
Almond Avenue Trailer Yard 4-54
b. Police Protection?
SWIP SP PEIR Finding: The SWIP SP PEIR determined that future development associated with the SWIP SP would
increase the need for police protection services within the SWIP SP area. However, all future development projects
located within the SWIP SP area would be required to pay the City’s development impact fee and the SWIP SP
PEIR included MMs 4.8-1a through 4.8-1i that established performance goals and identified community outreach
and involvement programs to ensure that acceptable police protection resources, service ratios, and response
times are met. The SWIP SP PEIR concluded that with payment of development impact fees and implementation
of the required mitigation, the SWIP SP would result in less-than-significant impacts regarding police protection
services.
Analysis of Project: The Project would develop the Project Site in accordance with the SWIP SP land use plan.
Accordingly, the development activities proposed by the Project were planned by the SWIP SP and, thus, the
Project’s demand for police protection services was anticipated by the SWIP SP PEIR. The Project Applicant would
also be required to pay applicable development impact fees, as specified in the SWIP SP PEIR, to offset its demand
for police protection services. (The City uses a portion of collected development impact fees to fund police
protection services/facilities.) Implementation of the Project would not result in any new impacts or more severe
impacts related to police protection services than previously disclosed in the SWIP SP PEIR.
Mitigation: No new or updated MMs are required. SWIP SP PEIR MMs 4.8-1a through 4.8-1i, which address
impacts to police protection services, are policy-level actions that fall under the City’s responsibility and do not
require any actions from private development projects. No component of the Project would prevent or obstruct
the City’s implementation of SWIP SP PEIR MMs 4.8-1a through 4.8-1i.
c. Schools?
SWIP SP PEIR Finding: The SWIP SP PEIR determined that future development associated with the SWIP SP could
increase the demand for public school services. However, all future development projects located within the SWIP
SP area would be required to pay the applicable school district development impact fee and the SWIP SP PEIR
included MM 4.8-3a through 4.8-3f to ensure that acceptable public-school resources are available. The SWIP SP
PEIR concluded that with payment of development impact fees and implementation of the required mitigation,
the SWIP SP would result in less-than-significant impacts regarding public school services.
Analysis of Project: The Project would develop the Project Site in accordance with the SWIP SP land use plan.
Accordingly, the development activities proposed by the Project were planned by the SWIP SP and, thus, the
Project’s indirect demand for public school services was anticipated by the SWIP SP PEIR. The Project Applicant
would be required to pay all applicable development impact fees, as required by State law, to offset its demand
for public school services. Implementation of the Project would not result in any new impacts or more severe
impacts related to school facilities than previously disclosed in the SWIP SP PEIR.
Mitigation: No new or updated MMs are required. SWIP SP PEIR MMs 4.8-3a through 4.8-3f, which address
impacts to public schools, are policy-level actions that fall under the City’s responsibility and do not require actions
from private development projects. No component of the Project would prevent or obstruct the City’s
implementation of SWIP SP PEIR MMs 4.8-3a through 4.8-3f.
Addendum to the
SWIP Specific Plan Update and Annexation PEIR Environmental Analysis
Almond Avenue Trailer Yard 4-55
d. Parks?
SWIP SP PEIR Finding: The SWIP SP PEIR determined that future development associated with the SWIP SP could
attract new residents to the City of Fontana that would increase the demand for parks and recreation facilities in
the City. The SWIP SP does not propose any new neighborhood and community park facilities nor does the SWIP
SP propose any development that would directly contribute park development impact fees to the City (i.e.,
residential); therefore, existing recreational facilities within the City would be accessed by new residents indirectly
generated by the SWIP SP without the addition of new revenue sources to offset the potential deterioration of
such facilities. The SWIP SP PEIR concluded that future park and recreational facility impacts resulting from future
development associated with the SWIP SP would be significant and unavoidable. The SWIP SP PEIR included MMs
4.8-5a through 4.8-5g to ensure the City achieves park design requirements and parkland standards in other areas
of the City; nevertheless, the SWIP SP PEIR concluded that impacts would be significant and unavoidable after
mitigation.
Analysis of Project: The Project would develop the Project Site in accordance with the SWIP SP land use plan.
Accordingly, the development activities proposed by the Project were planned by the SWIP SP and, thus, would
not create a demand for public park areas that was not previously anticipated by the SWIP SP PEIR. (Although it
should be noted that, as a proposed industrial use, the Project is not anticipated to create a substantial demand
for public park facilities.) Implementation of the Project would not result in any new impacts or more severe
impacts related to park facilities than the significant and unavoidable impacts previously disclosed in the SWIP SP
PEIR.
Mitigation: No new or updated MMs are required. SWIP SP PEIR MMs 4.8-5a through 4.8-5g, which address
impacts to public parks, are policy-level actions that fall under the City’s responsibility and do not require actions
from private development projects. No component of the Project would prevent or obstruct the City’s
implementation of SWIP SP PEIR MMs 4.8-5a through 4.8-5g.
e. Other Public Facilities?
SWIP SP PEIR Finding: The SWIP SP PEIR disclosed that future industrial, commercial, and office development
associated with the SWIP SP would create substantial employment opportunities within the SWIP SP area, which
could, in turn, lead to a population increase within the City and an associated increase in demand for library
facilities. However, the SWIP SP PEIR determined that future development associated with the SWIP SP would not
significantly increase the demand for library services to the extent that would require construction of additional
library facilities. Additionally, library facility impact fees would be imposed on future development projects within
the SWIP SP area that would fund improvements to the library system. The SWIP SP PEIR also included MM 4.8-
4a, which tasked the City with pursuing opportunities to expand library services. The SWIP SP PEIR concluded that
with payment of library facility impact fees and implementation of mitigation, the SWIP SP would result in less-
than-significant impacts to library facilities.
Analysis of Project: The Project Applicant would develop the Project Site in accordance with the SWIP SP land use
plan. Accordingly, the development activities proposed by the Project were planned by the SWIP SP and, thus,
would not create a demand for public library services that was not previously anticipated by the SWIP SP PEIR.
Addendum to the
SWIP Specific Plan Update and Annexation PEIR Environmental Analysis
Almond Avenue Trailer Yard 4-56
The Project Applicant would be required to pay all applicable development impact fees, as specified in the SWIP
SP PEIR, to offset its demand for public library services and ensure that impacts to public library services remain
less than significant. (The City uses a portion of collected development impact fees to fund library facilities.)
Implementation of the Project would not result in any new impacts or more severe impacts related to other public
facilities than previously disclosed in the SWIP SP PEIR.
Mitigation: No new or updated MMs are required. SWIP SP PEIR MM 4.8-4a, which addresses impacts to other
public services, is a policy-level action that falls under the City’s responsibility and does not require actions from
private development projects. No component of the Project would prevent or obstruct the City’s implementation
of SWIP SP PEIR MM 4.8-4a.
4.16 Recreation
Would the Project:
a. Increase the use of existing neighborhood and regional parks or other recreational facilities such that
substantial physical deterioration of the facility would occur or be accelerated?
b. Include recreational facilities or require the construction or expansion of recreational facilities, which
might have an adverse physical effect on the environment?
SWIP SP PEIR Finding: The SWIP SP PEIR determined that future development associated with the SWIP SP could
attract new residents to the City of Fontana that would increase the demand for parks and recreation facilities in
the City. The SWIP SP does not propose any new neighborhood and community park facilities nor does the SWIP
SP propose any development that would directly contribute park development impact fees to the City (i.e.,
residential); therefore, existing recreational facilities within the City would be accessed by new residents indirectly
generated by the SWIP SP without the addition of new revenue sources to offset the potential deterioration of
such facilities. The SWIP SP PEIR concluded that future park and recreational facility impacts resulting from future
development associated with the SWIP SP would be significant and unavoidable. The SWIP SP PEIR included MMs
4.8-5a through 4.8-5g (which are policy-level actions that fall under the City’s responsibility, as noted above) to
ensure the City achieves park design requirements and parkland standards in other areas of the City; nevertheless,
the SWIP SP PEIR concluded that impacts would be significant and unavoidable after mitigation.
Analysis of Project: The Project would develop the Project Site in accordance with the SWIP SP land use plan.
Accordingly, the development activities proposed by the Project were planned by the SWIP SP and, thus, the
Project’s indirect demand for parks was anticipated by the SWIP SP PEIR. As a proposed industrial use, the Project
is not anticipated to create a substantial demand for public park facilities and is not anticipated to include any
action that would increase the availability of park land in the City. Implementation of the Project would not result
in any new impacts or more severe impacts related to recreational facilities than previously disclosed in the SWIP
SP PEIR.
4.17 Transportation
A Trip Generation Assessment (dated November 14, 2025) (Urban Crossroads, 2025b) was prepared for the Project
by Urban Crossroads, Inc. to quantify the total daily and peak hour traffic expected during Project and to quantify
Addendum to the
SWIP Specific Plan Update and Annexation PEIR Environmental Analysis
Almond Avenue Trailer Yard 4-57
the Project’s transportation impacts, respectively. The Trip Generation Assessment is included as Appendix L to
this EIR Addendum and its findings are incorporated into the analysis presented herein.
Would the Project:
a. Conflict with an applicable plan, ordinance or policy addressing the circulation system, including transit,
roadway, bicycle, and pedestrian facilities?
SWIP SP PEIR Finding: In accordance with Senate Bill (SB) 743, the California Natural Resources Agency adopted
revisions to the CEQA Guidelines in December 2018 related to the evaluation of transportation impacts. With the
adoption of these revisions, automobile delay, measured by level of service (LOS) or similar metrics, no longer
constitutes a significant environmental effect under CEQA. Accordingly, the following information is provided for
informational purposes only and does not relate to a CEQA transportation impact or mitigation requirement.
The Project Site is located within the SID of the SWIP SP. The SID allows for a mixture of industrial, manufacturing,
warehousing, logistics, and service commercial uses, with a maximum buildout of approximately 2,540,637 square
feet. According to the SWIP Project Traffic Analysis, buildout of the SID would generate approximately 8,358 two-
way trips per day, including 987 trips during the AM peak hour and 1,046 trips during the PM peak hour, based on
1,705,576 square feet of warehousing/light industrial/service commercial uses on 126.2 acres. This equates to an
average trip generation rate of approximately 66.23 daily trips per acre, 7.82 AM peak hour trips per acre, and
8.29 PM peak hour trips per acre within the SID.
The SWIP SP PEIR disclosed that the addition of traffic associated with buildout of the SWIP Specific Plan would
cause nine (9) roadway segments and 19 intersections within the study area to operate at deficient levels under
the “Existing with Project” traffic analysis scenario. The SWIP Specific Plan EIR determined that implementation
of mitigation measures MM 4.9-1a through 4.9-1cc, which include roadway widenings, signalization, and
intersection improvements, would improve operations to satisfactory levels of service. However, because many
of the recommended improvements were unfunded or only partially funded at the time of approval and several
improvements were located outside the City of Fontana’s jurisdiction, the SWIP Specific Plan EIR concluded that
transportation impacts would be significant and unavoidable in the short term.
The SWIP Specific Plan EIR further disclosed that, under long-term (2030) buildout conditions, traffic associated
with the Specific Plan would contribute to deficient operations at 10 roadway segments and 19 intersections.
While implementation of mitigation measures MM 4.9-1dd through 4.9-1ll would improve operations to
satisfactory levels of service, full implementation of these improvements could not be assured. Accordingly, the
SWIP Specific Plan EIR concluded that transportation impacts would remain significant and unavoidable under
long-term conditions.
Analysis of Project: The proposed Project is calculated to generate 238 actual vehicle trips per day, consisting of
100 passenger vehicle trips and 138 truck trips, and 15 AM peak hour and 18 PM peak hour trips (Urban
Crossroads, 2025b, p. 3). When converted to passenger car equivalent (PCE) factors, the Project is estimated to
generate 514 PCE trips per day, including 33 PCE trips during the AM peak hour and 38 PCE trips during the PM
peak hour (Urban Crossroads, 2025b, p. 3). Under the currently approved SWIP land use assumptions, the Project
Site would otherwise be expected to generate 630 daily trips, including 74 AM peak hour trips and 79 PM peak
Addendum to the
SWIP Specific Plan Update and Annexation PEIR Environmental Analysis
Almond Avenue Trailer Yard 4-58
hour trips (Urban Crossroads, 2025b, p. 4). Therefore, the Proposed Project represents a reduction of 116 daily
trips, 41 fewer AM peak hour trips, and 41 fewer PM peak hour trips compared to the traffic levels assumed within
the SID by the SWIP SP PEIR (Urban Crossroads, 2025b, p. 5).
Because the Project would result in a substantial reduction in total daily and peak hour traffic relative to the
assumptions used in the SWIP SP PEIR, implementation of the Project would neither result in new significant
transportation impacts that were not disclosed in the SWIP SP PEIR nor substantially increase the severity of the
significant transportation effects previously identified in the SWIP SP PEIR. The reduction in expected traffic within
the SWIP SP area would not avoid any of the significant and unavoidable traffic impacts previously identified in
the SWIP SP PEIR, although traffic level of service is no longer considered an environmental impact under CEQA.
Mitigation: In accordance with Senate Bill (SB) 743, the California Natural Resources Agency adopted revisions to
the CEQA Guidelines in December 2018 related to the evaluation of transportation impacts. With the adoption of
these revisions, automobile delay, measured by level of service (LOS) or similar metrics, no longer constitutes a
significant environmental effect under CEQA. Accordingly, the following information is provided for informational
purposes only and does not relate to a CEQA transportation impact or mitigation requirement.
Due to the relatively small volume of peak hour traffic generated by the Project and the Project Site’s location,
which does not abut any roadway facility identified in the SWIP SP PEIR as requiring improvement, the City of
Fontana Engineering Department determined that the Project is not responsible for directly implementing any of
the transportation improvements identified in the SWIP SP PEIR. However, prior to issuance of building permits,
the Project Applicant would be required to pay applicable development impact fees to the City, from which the
City would allocate a portion toward the design and construction of roadway improvements that enhance
circulation within the City generally and within the SWIP SP area specifically. In addition, as part of the Project’s
construction, the Applicant would improve the west side of Almond Avenue along the Project Site frontage,
thereby implementing elements of the SWIP SP Circulation Master Plan and improving local vehicular and non-
vehicular circulation.
b. Conflict or be inconsistent with CEQA Guidelines section 15064.3 or will conflict with an applicable
congestion management program, including, but not limited to, level of service standards and travel
demand MMs, or other standards established by the county congestion management agency for
designated roads or highways?
SWIP SP PEIR Finding: The topic of vehicle miles traveled (VMT) was not specifically addressed in the SWIP SP PEIR
as this threshold of significance was not in place at the time the SWIP SP PEIR was certified 2. Notwithstanding,
VMT was assessed as part of the air quality impact analysis included as part of the SWIP SP PEIR. Thus, the SWIP
SP PEIR contained sufficient information about projected VMT resulting from vehicle trips originating from or
terminating within the SWIP SP area that associated effects could be determined by the public with the exercise
of reasonable diligence.
2 Changes in CEQA analytical methodologies, significance thresholds, or regulatory requirements do not constitute “new information”
requiring supplemental environmental review where the underlying environmental issue was known and addressed at the time the prior
EIR was certified. (Concerned Dublin Citizens v. City of Dublin (2013) 214 Cal.App.4th 1301, 1320; Olen Properties Corp. v. City of Newport
Beach (2023) 93 Cal.App.5th 270, 280; Hilltop Group Inc. v. County of San Diego (2024) 99 Cal.App.5th 890.)
Addendum to the
SWIP Specific Plan Update and Annexation PEIR Environmental Analysis
Almond Avenue Trailer Yard 4-59
The SWIP SP PEIR determined that because the City has a standard program (Circulation Development Fees) to
fund regional improvements, the San Bernardino Associated Governments (SANBAG) considers the City exempt
from congestion management plan (CMP) traffic impact analysis and no CMP analysis was required for the SWIP
SP. (Since certification of the SWIP SP PEIR, SANBAG was re-organized as the San Bernardino County
Transportation Authority [SBCTA].)
Analysis of Project: CEQA Guidelines Section 15064.3(c) is clear that “[t]he provisions of [Section 15064.3] shall
apply prospectively as described in [CEQA Guidelines] Section 15007.” CEQA Guidelines Section 15007(c)
specifically states: “[i]f a document meets the content requirements in effect when the document is sent out for
public review, the document shall not need to be revised to conform to any new content requirements in
Guideline amendments taking effect before the document is finally approved.” The CEQA Guidelines changes with
respect to VMT took effect on July 1, 2020, whereas the SWIP SP PEIR was certified in 2012. As such, and in
accordance with CEQA Guidelines Sections 15064.3(c) and 15007(c), revisions to the SWIP SP PEIR are not required
under CEQA in order to conform to the new requirements established by CEQA Guidelines Section 15064.3.
Once a project is approved, CEQA does not require that it be analyzed anew every time another discretionary
action is required to implement the project. Quite the opposite, where an EIR or MND has previously been
prepared for a project, CEQA expressly prohibits agencies from requiring a subsequent or supplemental EIR or
MND, except in specified circumstances (Pub. Res. Code Section 21166.). Under CEQA, “Section 21166 comes into
play precisely because in-depth review has already occurred, the time for challenging the sufficiency of the original
EIR has long since expired, and the question is whether circumstances have changed enough to justify repeating
a substantial portion of the process.” (Citizens Against Airport Pollution v. City of San Jose (“CAAP”) (2014), 227
Cal.App.4th at 796.) There was no CEQA requirement to analyze VMT at the time the SWIP SP PEIR was certified;
thus, there is no need to analyze VMT impacts in connection with this EIR Addendum.
Furthermore, the new VMT requirements set forth by CEQA Guidelines Section 15064.3 do not relate to a different
type of impact, but merely a different way of analyzing transportation impacts. The SWIP SP PEIR included a
detailed assessment of potential impacts, including potential impacts to air quality as a result of projected VMT.
As this information was disclosed as part of the SWIP SP PEIR, VMT associated with buildout of the SWIP SP do
not comprise “new information” that was not known or could not have been known at the time the SWIP SP PEIR
was certified. Because VMT impacts were known, the adoption of the requirement to analyze VMT therefore does
not constitute significant new information requiring preparation of a subsequent or supplemental EIR. Concerned
Dublin Citizens v. City of Dublin (2013) 214 Cal.App.4th 1301, 1320.
In the case of the proposed Project, there are no changed circumstances that would warrant additional analysis
under Public Resources Code Section 21166. The results of any VMT analysis would show that VMT from the
Project is less than what would occur under the development assumptions utilized in the SWIP SP PEIR, based on
the Project’s substantial reduction in passenger vehicle and heavy truck traffic relative to the calculations utilized
in the SWIP SP PEIR. As shown in the preceding response, the Project is calculated to eliminate 116 daily vehicle
traffic trips within the SWIP SP area based on the original traffic generation factors that were assumed in the SWIP
SP PEIR. Therefore, there is substantial evidence that the Project as proposed would result in reduced VMT as
compared to the project evaluated by the SWIP SP PEIR.

SWIP Specific Plan Update and Annexation PEIR Environmental Analysis

Regarding the Project’s potential to conflict with the applicable congestion management program (the San
Bernardino County Congestion Management Program), the Project would not contribute substantial traffic, which
is defined as 50 or more peak hour trips, to any San Bernardino County Congestion Management Program facility
and, therefore, would have no potential to result in substantial adverse effects/conflicts to appliable level of
service standards. Implementation of the Project would not result in any impacts that were not previously
disclosed in the SWIP SP PEIR.
Therefore, and based on the foregoing analysis, the Project would not result in any new impacts not already
analyzed in the SWIP SP PEIR, and the Project would not increase the severity of a significant impact as previously
identified and analyzed in the SWIP SP PEIR.
c. Substantially increase hazards due to a geometric design feature (e.g., sharp curves or dangerous
intersections) or incompatible uses (e.g., farm equipment)?
SWIP SP PEIR Finding: The SWIP SP PEIR did not identify any safety hazards related to a design feature or land use
proposed by the SWIP SP.
Analysis of Project: City staff reviewed the Project’s design for conformance with applicable City
engineering/design standards. Additionally, the Project Applicant would not introduce an incompatible use to the
Project Site, as the Project area is mostly developed with industrial land uses and truck traffic is commonplace on
roadways in the vicinity of the Project Site. Implementation of the Project would not result in any new impacts or
more severe impacts related to hazards due to a geometric design feature than previously disclosed in the SWIP
SP PEIR.
d. Result in inadequate emergency access?
SWIP SP PEIR Finding: The SWIP SP PEIR did not identify substantial adverse impacts related to inadequate
emergency access. The SWIP SP PEIR concluded that potential impacts to emergency access caused by
construction activities associated with the SWIP SP would be addressed through the required implementation of
a traffic management plan, which would reduce impacts to less than significant. The SWIP SP PEIR concluded that
the improvements proposed by the SWIP SP would be implemented in a manner that would improve local
circulation and emergency access, and, therefore, impacts would be less than significant without the need for
mitigation.
Analysis of Project: The Project would construct industrial land uses on the Project Site, which would require the
need for emergency access to-and-from the Project Site. The City reviewed the Project’s design to ensure that
adequate access to-and-from the site would be provided for emergency vehicles. The City also will require the
Project to provide adequate paved access to-and-from the site (via a condition of approval) and will review all
future Project construction drawings to ensure that adequate emergency access is maintained along abutting
public streets during temporary construction activities. Implementation of the Project would not result in any new
impacts or more severe impacts related to inadequate emergency access than previously disclosed in the SWIP SP
PEIR.

4.18 Tribal Cultural Resources
Assembly Bill 52 (AB 52) was signed into law in 2014 and added the topic of “Tribal Cultural Resources” to Appendix
G of the CEQA Guidelines, including the thresholds listed below. Thus, at the time the SWIP SP PEIR was certified
in 2012, AB 52 was not in place and the SWIP SP PEIR did not specifically address this topic. Notwithstanding, the
SWIP SP PEIR disclosed substantial information regarding cultural resources, including sites, places, and objects
that have cultural value to a California Native American tribe, within the SWIP SP study area and provided a
detailed analysis of potential impacts to these resources (see Section 4.5 of this EIR Addendum). As such,
information about tribal cultural resources was available with the exercise of reasonable diligence at the time the
SWP SP PEIR was certified in 2012, and the topic of tribal cultural resources does not represent new information
of substantial importance which was not known and could not have been known at the time that the SWIP SP PEIR
was certified. During the public review period and public hearings associated with the SWIP SP PEIR, no objections
or concerns were raised regarding the EIR’s analysis of tribal cultural resources, and no legal challenge was filed
within the statute of limitations period established by Public Resources Code §21167(c). Pursuant to CEQA case
law and CEQA Guidelines Section 15162(a)(3), the topic of tribal cultural resources does not provide new
information of substantial importance or substantial evidence of a new impact to the environment that was not
or could not have been known at the time the SWIP SP PEIR was certified.
Furthermore, AB 52 is applicable to all development projects for which a Notice of Preparation of an EIR (NOP) or
a notice of intent to adopt a negative declaration (NOI) was circulated for public review on or after July 1, 2015.
Because the NOP for the SWIP SP PEIR was published prior to July 1, 2015, and the Project does not require the
publication of a new NOP because it is following the implementation process for the SWIP SP, AB 52’s
requirements to evaluate potential impacts to tribal cultural resources is not applicable to the Project.
Would the project cause a substantial adverse change in the significance of a tribal cultural resource, defined in
Public Resources Code Section 21074 as either a site, feature, place, cultural landscape that is geographically
defined in terms of the size and scope of the landscape, sacred place, or object with cultural value to a California
Native American tribe, and that is:
a. Listed or eligible for listing in the California Register of Historical Resources, or in a local register of
historical resources as defined in Public Resources Code Section 5020.1(k)?
SWIP SP PEIR Finding: Although the SWIP SP PEIR did not specifically address this subject, the SWIP SP PEIR
disclosed all recorded historical resources in the SWIP SP area and identified the potential for discovery of historic
and archaeological resources during earth moving construction activity. Mitigation was included in the SWIP SP
PEIR to reduce impacts to historical and archaeological resources to a level below significance.
Analysis of Project: The Project Site, which the SWIP SP PEIR assumed would be fully developed, does not have
any resources listed or eligible for listing in the California Register of Historical Resources, or in any local register
of historical resources (refer to Response 4.5(a)). Accordingly, the Project would not impact a tribal cultural
resource that is listed or eligible for listing in the California Register of Historical Resources, or in a local register
of historical resources as defined in Public Resources Code Section 5020.1(k). Implementation of the Project would
not result in any new or more severe significant impacts related to tribal cultural resources than previously
disclosed in the SWIP SP PEIR.

SWIP Specific Plan Update and Annexation PEIR Environmental Analysis
Almond Avenue Trailer Yard 4-62
b. A resource determined by the lead agency, in its discretion and supported by substantial evidence, to be
significant pursuant to criteria set forth in subdivision (c) of Public Resources Code Section 5024.1? In
applying the criteria set forth in subdivision (c) of Public Resources Code Section 5024.1, the lead agency
shall consider the significance of the resource to a California Native American tribe.
SWIP SP PEIR Finding: Although the SWIP SP PEIR did not specifically address this subject, the SWIP SP PEIR
contained sufficient information related to the SWIP SP’s cultural setting to conclude that there was the potential
for tribal cultural resources to be located within the SWIP SP area.
Analysis of Project: The Project Site is highly disturbed, and no known tribal cultural resources were determined
to occur on the Project Site or in the Project Site’s immediate vicinity (refer to Item “b” under Subsection 4.5 of
this EIR Addendum). Notwithstanding, as a standard practice for all development projects in Fontana, the City
would require the Project Applicant to comply with conditions of approval that establish protocols for
consultation, monitoring, and resource recovery to protect inadvertent discoveries of buried/masked prehistoric
archaeological resources. The City’s standard conditions of approval would be consistent with SWIP SP PEIR MMs
4.4-1b, 4.4-2b, and 4.4-2c. Mandatory compliance with the City’s standard conditions of approval (which would
ensure implementation of SWIP SP EIR MMs 4.4-1a, 4.4-1b, 4.4-2a, and 4.4-2b) would preclude potential impacts
to tribal cultural resources as defined in Public Resources Code 5024.1(c). Implementation of the Project would
not result in any new or more severe significant impacts related to tribal cultural resources than previously
disclosed in the SWIP SP PEIR.
Mitigation: No new or updated MMs are required. SWIP SP EIR MMs 4.4-2b and 4.4-2c apply to the Project, as
presented in Subsection 4.5 of this EIR Addendum and in the MMRP for the SWIP SP PEIR, attached hereto as
Appendix A.
4.19 Utilities and Service Systems
Would the Project:
a. Require or result in the relocation or construction of new or expanded water, wastewater treatment or
storm water drainage, electric power, natural gas, telecommunication facilities, the construction or
relocation of which could cause significant environmental effects?
SWIP SP PEIR Finding: The SWIP SP PEIR disclosed that each future development proposal within the SWIP SP area
will be reviewed by the City staff to confirm that utility/infrastructure improvements would be available to serve
the project or that improvements planned by the SWIP SP would be installed as part of development.
Analysis of Project: The utility and infrastructure improvements proposed by the Project Applicant are discussed
in Section 3.0 of this EIR Addendum. The installation of the infrastructure improvements proposed by the Project
Applicant would result in physical environmental impacts; however, these impacts have already been disclosed
throughout this EIR Addendum and were determined to be within the scope of the analysis for the SWIP SP PEIR.
b. Have sufficient water supplies available to serve the project and reasonably foreseeable future
development during normal, dry, and multiple dry years?
Addendum to the
SWIP Specific Plan Update and Annexation PEIR Environmental Analysis
Almond Avenue Trailer Yard 4-63
SWIP SP PEIR Finding: The SWIP SP PEIR concluded that the City would have sufficient water supply to meet the
water demands of the SWIP SP in addition to the City’s existing and projected future service obligations.
Analysis of Project: The Project would implement industrial land uses on the Project Site in accordance with the
SWIP SP land plan. Accordingly, the development activities and water demand proposed by the Project were
planned by the SWIP SP and, therefore, anticipated by the SWIP SP PEIR. Furthermore, the FWC’s 2020 Urban
Water Management Plan (UWMP), which anticipates buildout of the SWIP SP and its associated water demand,
indicates that the FWC has sufficient water supplies to meet its service demand for normal, single-dry year, and
multiple-dry year conditions through at least the year 2045 (FWC, 2021, pp. 7-6 - 7-8). Accordingly, the Project
would not require new or expanded water entitlements. Implementation of the Project would not result in any
new impacts or more severe impacts related to water supplies than previously disclosed in the SWIP SP PEIR.
c. Result in a determination by the wastewater treatment provider, which serves or may serve the project,
that it has adequate capacity to serve the project’s projected demand in addition to the provider’s existing
commitments?
SWIP SP PEIR Finding: The SWIP SP PEIR determined that existing wastewater treatment facilities could
accommodate the SWIP SP’s demand for wastewater treatment services.
Analysis of Project: The SWIP Specific Plan EIR determined that existing wastewater collection and treatment
facilities have adequate capacity to accommodate wastewater flows associated with buildout of the SWIP Specific
Plan area. The proposed Project is consistent with the land use types and development intensity evaluated in the
SWIP Specific Plan EIR. The proposed Project would generate minimal wastewater, limited primarily to domestic
wastewater from a small office restroom. Water use associated with on-site landscaping would not contribute to
wastewater flows. Wastewater generated by the Project would be conveyed to existing wastewater collection
and treatment facilities serving the SWIP Specific Plan area. The Project would not require the construction of new
or expanded wastewater treatment facilities. Accordingly, the Project would not result in a determination by the
wastewater treatment provider that it lacks adequate capacity to serve the Project’s demand in addition to
existing commitments, and would not result in new or more severe wastewater-related impacts beyond those
previously disclosed in the SWIP SP PEIR.
d. Generate solid waste in excess of State or local standards, or in excess of the capacity of local
infrastructure, or otherwise impair the attainment of solid wastes reduction goals?
SWIP SP PEIR Finding: Solid waste from the SWIP SP area would be disposed at the Mid-Valley Landfill. The SWIP
SP PEIR determined that the Mid-Valley Landfill has sufficient capacity to accommodate the solid waste disposal
needs of the SWIP SP. The SWIP SP PEIR incorporated mitigation from the City of Fontana General Plan EIR that
pertain to solid waste as MMs 4.8-9a through 4.8-9d to further reduce the amount of solid waste that would be
diverted to the Mid-Valley Landfill. (SWIP SP PEIR MMs 4.8-9a through 4.8-9d are policy-level actions that are the
responsibility of the City that do not require any actions of development projects.)
Analysis of Project: Construction of the proposed Project would involve primarily site preparation activities,
including removal of existing site features, grading, and paving, as well as installation of prefabricated structures.
As a result, construction-related solid waste would be limited, temporary, and typical of site improvement
Addendum to the
SWIP Specific Plan Update and Annexation PEIR Environmental Analysis
Almond Avenue Trailer Yard 4-64
activities. Operational solid waste generation would be minimal and associated primarily with routine office and
site maintenance activities. Solid waste generated by the Project would be collected and disposed of in accordance
with State and local regulations, including compliance with CalGreen requirements, which requires a minimum of
65 percent of all solid waste be diverted from landfills (by recycling, reusing, and other waste reduction strategies)
(CalGreen, 2022); for construction and operational waste diversion. Given the Project’s limited solid waste
generation and its consistency with the land use assumptions evaluated in the SWIP SP PEIR, the Project would
not generate solid waste in excess of State or local standards, would not exceed the capacity of local solid waste
infrastructure, and would not impair the attainment of applicable solid waste reduction goals. The Project would
not result in new or more severe solid waste impacts beyond those previously disclosed in the SWIP Specific Plan
EIR.
e. Comply with federal, State, and local management and reduction statutes and regulations related to solid
wastes?
SWIP SP PEIR Finding: The SWIP SP PEIR concluded that SWIP SP would be in compliance with all State and local
requirements related to solid waste. Therefore, impacts would be less than significant.
Analysis of Project: The Project would be required to comply with Chapter 24 of the City’s Municipal Code, which
would require future tenants of the Project to segregate and place solid waste generated by the Project into
containers for collection. There are no components of the Project that would result in non-compliance with
federal, state, or local statutes or regulations related to solid waste. Implementation of the Project would not
result in any new or more severe significant impacts related to conflicts with federal, State, and local management
and reduction statues than previously disclosed in the SWIP SP PEIR.
4.20 Wildfire
If located in or near state responsibility areas or lands classified as very high fire hazard severity zones would the
project:
a. Substantially impair an adopted emergency response plan or emergency evacuation plan?
b. Due to slope, prevailing winds, and other factors exacerbate wildfire risks and thereby expose project
occupants to, pollutant concentrations from a wildfire or the uncontrolled spread of a wildfire?
c. Require the installation or maintenance of associated infrastructure (such as roads, fuel breaks, emergency
water sources, power lines or other utilities) that may exacerbate fire risk or that may result in temporary
ongoing impact to the environment?
d. Expose people or structures to significant risks, including downslope or downstream flooding or landslides,
as a result of runoff, post-fire slope instability, or drainage changes?
SWIP SP PEIR Finding: The SWIP SP PEIR determined that the SWIP SP is located in an urbanized area, and no
wildlands exist in the vicinity of the SWIP SP area. The SWIP SP PEIR concluded that no impact related to wildland
hazards would occur.
Analysis of Project: The Project Site is not located in or near a state responsibility area or lands classified as very
high fire hazard severity zones (CAL FIRE, 2024; City of Fontana, 2018b); therefore, implementation of the Project
Addendum to the
SWIP Specific Plan Update and Annexation PEIR Environmental Analysis
Almond Avenue Trailer Yard 4-65
would not exacerbate existing wildfire hazard risks or expose people or the environment to adverse environmental
effects related to wildfires within a state responsibility area or very high fire hazard severity zone. The SWIP SP
PEIR assumed the Project Site would be developed. Implementation of the Project would not result in any new or
more severe significant impacts related to wildfire hazards than previously disclosed in the SWIP SP PEIR.
4.21 Mandatory Findings of Significance
Does the Project:
a. Have the potential to substantially degrade the quality of the environment, substantially reduce the
habitat of a fish or wildlife species, cause a fish or wildlife population to drop below self-sustaining levels,
threaten to eliminate a plant or animal community, substantially reduce the number or restrict the range
of a rare or endangered plant or animal, or eliminate important examples of the major periods of California
history or prehistory?
SWIP SP PEIR Finding: The SWIP SP PEIR concluded that, following mitigation, the SWIP SP would result in less-
than-significant impacts to sensitive plant and animal species as well as habitats. Additionally, the SWIP SP PEIR
concluded that, with mitigation, the SWIP SP would result in less-than-significant impacts to archaeological,
historical, and paleontological resources, and, therefore, would not eliminate important examples of major
periods of California history or prehistory.
Analysis of Project: As indicated throughout the analysis presented herein, implementation of the Project would
not substantially degrade the quality of the environment, substantially reduce the habitat of fish or wildlife
species, cause a fish or wildlife populations to drop below self-sustaining levels, threaten to eliminate a plant or
animal community, or reduce the number or restrict the range of a rare or endangered plant or animal, or
eliminate important examples of the major periods of California history or prehistory, to a greater degree than
previously disclosed in the SWIP SP PEIR.
b. Have impacts that are individually limited, but cumulatively considerable? (“Cumulatively considerable”
means that the incremental effects of a project are considerable when viewed in connection with the
effects of past projects, the effects of other current projects, and the effects of probable future projects)?
SWIP SP PEIR Finding: The SWIP SP PEIR addressed cumulative impacts for each of the environmental topics
evaluated. The SWIP SP PEIR concluded the SWIP SP would result in significant and unavoidable cumulative
impacts regarding the following issues:
• Aesthetics (scenic vistas);
• Air Quality (construction-related and operational emissions);
• Noise (long-term mobile noise and increases to incremental noise levels);
• Recreation (parks/recreation facilities); and
• Transportation/Traffic (roadway segments/intersections performance).
Analysis of Project: As described throughout this analysis, implementation of the Project would not result in new
environmental impacts that were not previously disclosed in the SWIP SP PEIR and would not increase the severity
Addendum to the
SWIP Specific Plan Update and Annexation PEIR Environmental Analysis
Almond Avenue Trailer Yard 4-66
of environmental impacts disclosed in the SWIP SP PEIR. There is also no new information of substantial
importance since the time the SWIP SP PEIR was certified that was not already known and analyzed in the SWIP
SP PEIR. Therefore, there is no potential for the Project to result in cumulatively considerable effects to the
environment beyond those previously disclosed in the SWIP SP PEIR (and already disclosed throughout this
analysis), and instead, the Project’s impacts are generally less than the impacts assumed and analyzed in the SWIP
SP PEIR. The SWIP SP PEIR concluded that cumulative effects would be significant and unavoidable for the topics
of aesthetics, air quality, noise, recreation, and transportation and traffic.
c. Have environmental effects, which will cause substantial adverse effects on human beings, either directly
or indirectly?
SWIP SP PEIR Finding: The SWIP SP PEIR concluded that while changes to the environment that could indirectly
affect human beings would be possible in all of the designated CEQA issue areas, those changes to the
environment that the SWIP SP would cause that could directly affect human beings include:
• Air Quality (construction-related and operational emissions);
• Hazards and Hazardous Materials (contaminated soil and groundwater [SWIP SP PEIR concluded impacts
in this issue area would be less than significant with implementation of MMs]);
• Noise (long-term mobile noise and increases to incremental noise levels);
• Recreation (parks/recreation facilities); and
• Transportation/Traffic (roadway segments/intersections performance).
Analysis of Project: Implementation of the Project would not result in environmental effects that would cause
substantial adverse effects on human beings, either directly or indirectly, beyond those disclosed in the SWIP SP
PEIR, and instead, the Project’s impacts are generally less than the impacts assumed and analyzed in the SWIP SP
PEIR.
