City of Fontana | Addendum to the General Plan FEIR for the
Community Mobility and Circulation Element Update
Introduction 1
1 INTRODUCTION
1.1 PURPOSE AND BACKGROUND
On November 13, 2018, the City Council certified the Fontana Forward General Plan Update 2015-
2035 Final Environmental Impact Report (State Clearinghouse [SCH] # 2016021099) (General Plan
FEIR) and adopted the Fontana Forward General Plan Update 2015-2035, which modernized the
Community Mobility and Circulation Element among other chapters. Since certification of the
2018 General Plan FEIR, the City and its regional partners have advanced the transportation vision
through regional corridor studies and by adopting Industrial Commerce Centers Sustainability
Standards (FMC Ch. 9, Art. V) requiring Truck Routing Plans tied to the City’s adopted truck-route
map and related signage/enforcement.
On September 24, 2024, Assembly Bill (AB) 98 was signed into law requiring all cities and counties
in the warehouse concentration region, which includes Fontana, to update its Community Mobility
and Circulation Element to include truck routes meeting certain requirements. More specifically,
AB 98 requires the City to identify and establish specific travel routes for the transport of goods,
materials, or freight for storage, transfer, or redistribution to safely accommodate additional truck
traffic and avoid residential areas and sensitive receptors. The City is also required to maximize the
use of interstate or state divided highways as preferred routes for truck routes, and maximize use
of arterial roads, major thoroughfares, and predominantly commercially oriented local streets
when state or interstate highways are not utilized. On October 3, 2025, Senate Bill 415 (SB 415) was
signed into law providing various clarifications to AB 98. However, SB 415 did not alter the
requirements set forth by AB 98 for circulation element updates for cities and counties in the
warehouse concentration region, such as Fontana.
The City has prepared an Addendum to the General Plan FEIR for the Community Mobility and
Circulation Element Update (referenced herein as “Project” or “proposed Project”). The Project
establishes a comprehensive citywide truck-route network, updates the Community Mobility and
Circulation Element text and mapping, refines goals and policies to improve goods movement
efficiency, reduces conflicts with sensitive land uses, and aligns local policy with State freight and
greenhouse gas reduction initiatives, in compliance with AB 98. The Project does not modify any
existing land use designations, nor does it increase development capacity beyond the levels
evaluated in the General Plan FEIR; refer to Section 2 for more detail.
1.2 CEQA REQUIREMENTS
The City of Fontana is the Lead Agency under the California Environmental Quality Act (CEQA)
for the Addendum to the General Plan FEIR for the Community Mobility and Circulation Element
Update Project.
The purpose of this document is to analyze the potential differences between the impacts
identified in the General Plan FEIR and those that would potentially be associated with the
proposed Project.
City of Fontana | Addendum to the General Plan FEIR for the
Community Mobility and Circulation Element Update
Introduction 2
As part of its decision-making process, the City is required to review and consider whether the
proposed Project would create new significant impacts or significant impacts that would be
substantially more severe than those disclosed in the General Plan FEIR. (Public Resource Code §
21166; CEQA Guidelines § 15162.) If major revisions to the General Plan FEIR are not necessary and
none of the conditions described in State CEQA Guidelines Section 15162 calling for the
preparation of additional CEQA documentation has occurred, the City may adopt an Addendum
to the General Plan FEIR to document its findings that no subsequent or supplemental CEQA
document is required. (CEQA Guidelines § 15164.)
Specifically, after approving a project and prior to approving further discretionary action for that
project, depending upon the situation, the lead agency must generally: (1) prepare a Subsequent
EIR; (2) prepare a Supplemental EIR; (3) prepare a Subsequent Negative Declaration; (4) prepare
an Addendum to the EIR or Negative Declaration; or (5) prepare no further documentation. (See
State CEQA Guidelines, §§ 15162 – 15164.) State CEQA Guidelines Section 15162 states:
When an EIR has been certified or a negative declaration adopted for a project, no subsequent
EIR shall be prepared for that project unless the lead agency determines, on the basis of
substantial evidence in the light of the whole record, one or more of the following:
(1) Substantial changes are proposed in the project which will require major revisions of
the previous EIR or negative declaration due to the involvement of new significant
environmental effects or a substantial increase in the severity of previously identified
significant effects;
(2) Substantial changes occur with respect to the circumstances under which the project
is undertaken which will require major revisions of the previous EIR or Negative
Declaration due to the involvement of new significant environmental effects or a
substantial increase in the severity of previously identified significant effects; or
(3) 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 or the Negative Declaration was adopted, shows any of the
following:
(A) The project will have one or more significant effects not discussed in the previous
EIR or negative declaration;
(B) Significant effects previously examined will be substantially more severe than
shown in the previous EIR;
(C) Mitigation measures 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 mitigation measure
or alternative; or
City of Fontana | Addendum to the General Plan FEIR for the
Community Mobility and Circulation Element Update
Introduction 3
(D) Mitigation measures 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
mitigation measure or alternative.
Section 15164 of the State CEQA Guidelines explains when an Addendum to an EIR is appropriate.
Per this section, where some changes or additions are necessary to the previously certified EIR, but
none of the conditions described in Section 15162 calling for the preparation of a subsequent EIR
(as described above) have occurred, then the lead agency is directed to prepare an Addendum
to the certified EIR (State CEQA Guidelines, § 15164). Further, the Addendum should include a
“brief explanation of the decision not to prepare a subsequent EIR pursuant to Section 15162,”
and that “explanation must be supported by substantial evidence” (State CEQA Guidelines, §
15164 [e]). The Addendum need not be circulated for public review but may simply be attached
to the certified EIR (State CEQA Guidelines, § 15164 [c]).
1.3 INCORPORATION BY REFERENCE
The documents outlined below, which were utilized during preparation of this Addendum and are
a matter of public record, are hereby incorporated by reference.
Fontana Forward General Plan Update 2015–2035
The City Council adopted the Fontana Forward General Plan Update 2015–2035 on November
13, 2018. The General Plan is the city’s comprehensive policy document for long-range growth
and is organized into the seven State-mandated elements: Land Use, Community Mobility and
Circulation, Housing, Conservation, Open Space, Noise, and Safety, along with optional elements
addressing economic development, public health, infrastructure, sustainability, and downtown
revitalization. The plan projects citywide build-out to 2035, establishes land-use capacities for
residential, commercial, and industrial districts, and provides goals and policies for goods-
movement corridors that are the subject of this Truck Route Network Update.
Fontana Forward General Plan Update 2015–2035 Final EIR
The Final Environmental Impact Report for the Fontana Forward General Plan Update 2015–2035
was certified on August 10, 2018. The report evaluates the potential environmental effects of build-
out contemplated by the General Plan and identifies mitigation measures where feasible. Issues
addressed include transportation, air quality, greenhouse gas emissions, noise, biological
resources, cultural resources, hydrology, and hazards. Significant and unavoidable impacts were
identified for regional air quality and greenhouse gas emissions, while all other issue areas were
found to be less than significant after mitigation. The Final EIR serves as the environmental baseline
for this Addendum.

Community Mobility and Circulation Element Update
Introduction 4
Fontana Active Transportation Plan
The City of Fontana developed and approved an Active Transportation Plan (ATP) in 2017 to guide
infrastructure improvements towards improving mobility throughout the City through safe,
convenient, accessible, and comfortable walking and bicycling linkages. The following goals are
the most relevant to the Downtown Area Plan:
• Increase and improve pedestrian and bicyclist access to employment centers, schools,
transit, recreation facilities, and other community destinations through the City.
• Improve safety through the design and maintenance of sidewalks, streets, intersections,
and other roadway improvements such as signage, striping, lighting, wayfinding, and
landscaping
• Improve the quality, operation, and integrity of the pedestrian and bicycle network
infrastructure and facilities that allows for convenient and direct connections throughout
the City.
Within the Project Area, the ATP includes new planned bike facilities on Foothill Boulevard, Arrow
Boulevard, Valencia Avenue, Orange Way, Ceres Avenue, and Sierra Avenue.
City of Fontana Traffic Impact Analysis Guidelines
The City of Fontana developed their own traffic impact analysis (TIA) guidelines to consistently
assess the traffic impacts generated by development projects on the surrounding transportation
network. The TIA guidelines serve as a tool for the City to evaluate the effects a development will
have on the City’s transportation infrastructure, identify improvements required to maintain the
City’s Level of Service (LOS) standards and address Section XVII (Transportation) of Appendix G of
the California Environmental Quality Act (CEQA) Guidelines. The TIA guidelines include
requirements to determine the analysis study area, analyses scenarios, and analyses processes.
Finally, the TIA guidelines include recommendations for determining VMT impact thresholds and
mitigation requirements for various land use projects.
Fontana Municipal Code (FMC)
The Fontana Municipal Code implements General Plan policy through zoning, subdivision,
building, and street standards. FMC Chapter 17, Motor Vehicles and Traffic, contains ordinances
for traffic administration; operation of motor vehicles; stopping, standing and parking; loading and
unloading; pedestrians and bicycles; truck routes; funding of air pollution reduction programs; and
illegal street racing. Compliance with these code provisions will guide implementation of the
updated truck-route network and ensure consistency with General Plan policies and previously
adopted mitigation measures.
City of Fontana | Addendum to the General Plan FEIR for the
Community Mobility and Circulation Element Update
Description of the Proposed Project 5
2 DESCRIPTION OF THE PROPOSED PROJECT
2.1 PROJECT LOCATION AND SETTING
The City of Fontana is in southern San Bernardino County approximately 50 miles east of the City
of Los Angeles. Fontana is a rapidly growing urban community encompassing 52 square miles,
including the City’s Sphere of Influence (SOI). Fontana is in a valley and is adjacent to three major
transportation corridors, including Interstates 10 and 15 and State Route 210. Surrounding
communities are the cities of Rancho Cucamonga and Ontario to the west, the city of Rialto and
the unincorporated community of Bloomington to the east, the city of Jurupa Valley to the south,
and the San Gabriel Mountains and San Bernardino National Forest to the north. Regional access
to the City is provided via Interstate 10 (east-west), Interstate 15 (north-south), and State Route 210
(east-west); refer to Figure 1, Regional Location Map. Approximately 6,000 acres (11,000 acres in
the SOI) are designated for commercial and industrial uses; refer to Figure 2, General Plan Planning
Area.
2.2 PROJECT CHARACTERISTICS
In compliance with Assembly Bill 98 (AB 98), the City of Fontana has prepared a focused update
to its Community Mobility and Circulation Element, including its Truck Route Map to align the
General Plan with current regulatory requirements.
Community Mobility and Circulation Element Organization
The existing Community Mobility and Circulation Element is organized into the following sections:
Community Mobility and Circulation in the Fontana Forward Vision and Principles; Findings and
Challenges; Goals and Policies; Hierarchy of Streets in Fontana; What the Community Said; Policies
and Actions to Achieve the Goals; and Getting Started. The proposed update would maintain the
organization and structure of the existing Community Mobility and Circulation Element.
Summary of Community Mobility and Circulation Element Modifications
The City’s Community Mobility and Circulation Element would be amended primarily to
incorporate AB 98 requirements for a designated truck-route network, while keeping the broader
multi-modal framework established in the Fontana Forward General Plan Update 2015–2035. The
City’s existing Truck Route Map (Exhibit 9.7, Truck Routes) would be updated to shift truck traffic
away from residential uses and sensitive receptors, while also clarifying what facilities are officially
part of the City-controlled local truck route network. Figure 3, Proposed Truck Route Map, shows
the proposed updates to the City’s local truck route network. The proposed updated truck route
network would continue to provide access for industrial and similar uses, with parcels being within
a short drive to either local or regional truck routes.
City of Fontana | Addendum to the General Plan FEIR for the
Community Mobility and Circulation Element Update
Description of the Proposed Project 6
In addition, the Project proposes minor text changes to existing policies and actions in the City’s
Community Mobility and Circulation Element, as well as the addition of new policies and actions,
as described further below. The changes and additions would further address AB 98 requirements
to provide specific truck route requirements and avoid residential areas and sensitive receptors,
as well as direct the City towards meeting other AB 98 requirements. The following summarizes the
proposed modifications to the Community Mobility and Circulation Element, as compared to the
existing Community Mobility and Circulation Element. Changes are provided with double
underline for new text and strike through for deleted text.
Goal 2: Fontana’s street network is safe and accessible to all users, especially the most vulnerable
such as children, youth, older adults and people with disabilities.
• Modified Policy: Support Maintain a designated truck routes network that avoids negative
impacts on residential and commercial areas and other sensitive uses, while with arterial
streets accommodating the efficient movement of trucks on designated truck routes and
arterial streets.
• Modified Action G: Vigorously and consistently enforce speed limits, truck use of
designated truck routes, and other traffic laws.
• New Action O: Develop and maintain a citywide system of clear and conspicuous signage
denoting truck routes and other truck requirements and restrictions.
• New Action P: Maintain an up-to-date online map of citywide truck routes, and make
available maps and source data to local warehouse operators, fleet operators, and truck
drivers.
• New Action Q: Regularly review the citywide truck route map to see if changes in land use
or other conditions require updates to accommodate truck access and avoid sensitive
uses.
Goal 7: The city of Fontana participates in shaping regional transportation policies to reduce traffic
congestion and greenhouse gas emissions.
• New Policy: Coordinate with regional agencies and adjacent jurisdictions on regional
goods movement planning and cross-jurisdictional consistency.
• Modified Action D: Support the adoption and use of technologies that reduce emissions
from passenger, and transit, and goods movement vehicles.

3 ENVIRONMENTAL APPROACH AND ANALYSIS
This analysis has been prepared to determine whether the proposed Project could result in any
new significant impacts or a substantial increase in the severity of previously identified significant
impacts in the General Plan FEIR. This review is limited to evaluating whether the Project would
trigger further environmental analysis beyond the General Plan FEIR. This Addendum is intended
solely to analyze the impacts of the proposed update to the Community Mobility and Circulation
Element. The Project does not involve any site-specific development or infrastructure projects and
is not intended to serve as the environmental analysis for potential future site-specific or
infrastructure projects within the General Plan Planning Area.
This analysis is based on the CEQA Guidelines Appendix G Checklist and provides a summary of
impacts in the General Plan FEIR and the potential impacts associated with the Project. This
comparative analysis provides the City with the factual basis for determining whether the Project
would require additional environmental review such as the preparation of a Subsequent EIR or
Supplemental EIR.

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 point). If the
project is in an urbanized area,
would the project conflict with
applicable zoning and other
regulations governing scenic
quality?
X
d. Create a new source of
substantial light or glare which
would adversely affect day or
nighttime views in the area?
X
General Plan FEIR Conclusions
Would the project have a substantial adverse effect on a scenic vista?
The northern and southern portions of the City have direct lines of sight to the San Gabriel
Mountains and the Jurupa Hills, respectively (considered scenic resources for the FEIR analysis).
Since these areas of the City are closest in proximity to the San Gabriel Mountains and the Jurupa
Hills, the General Plan FEIR states that a potentially significant impact could occur if viewsheds to
these scenic resources were obscured by development.
In the north and south of the city, master planned communities developed through the specific
plan process since the 1980s are not expected to experience substantial land use changes over
the next 20 years, as these areas are built out. Therefore, the General Plan FEIR states that
viewsheds in these areas will be largely unaffected by the implementation of the General Plan
City of Fontana | Addendum to the General Plan FEIR for the
Community Mobility and Circulation Element Update
Addendum Finding 14
Update since few deviations in land use patterns are proposed in these areas. Changes
anticipated under implementation of the General Plan Update include enhancing connections
to local destinations (e.g., parks, schools, retail centers) through safe pedestrian and bicycle
routes, as well as walking trails. Such changes would be implemented at ground level and,
therefore, would not interrupt views of the scenic resources to the north and south (namely, the
mountains and hills). In addition, open spaces in these areas would be preserved, thereby
eliminating the potential for structural development to obscure viewsheds (only structures related
to the management of resources would be permitted).
Therefore, the General Plan FEIR concluded that compliance with identified goals, policies, and
actions of the General Plan Update and applicable regulations outlined in specific plans,
implementation of development associated with the General Plan Update will result in a less than
significant impact on scenic vistas.
Would the project substantially damage scenic resources, including, but not limited to, trees, rock
outcroppings, and historic buildings within a state scenic highway?
There are no officially designated or eligible state scenic highways within or adjacent to the
General Plan Planning Area, and no rock outcroppings exist within the City. As there are no
officially designated or eligible scenic highways within or adjacent to the Project area,
implementation of the General Plan Update was concluded to result in a less than significant
impact to scenic resources within a state scenic highway.
Would the project substantially degrade the existing visual character or quality of public views of
the site and its surroundings?
The General Plan Planning Area is urbanized and largely built out. In accordance with the Land
Use, Zoning, and Urban Design Element of the General Plan Update, future development within
the City would largely consist of infill development and redevelopment of previously built sites to
accommodate new growth, as well as annexation of land within the Sphere of Influence to
improve entrance corridors. In addition, the Community and Neighborhoods Element and
Downtown Area Plan identify the need to redevelop older neighborhoods; provide more
compact, walkable, mixed-use developments with new housing and shopping opportunities; and
revitalize the central core of the City. The ultimate design of these new developments could have
a potentially significant impact on visual character or quality of the Project area and its
surroundings.
Infill, redevelopment, and new construction would alter the visual character in areas in which that
development would occur. However, the Land Use, Zoning, and Urban Design Element provides
specific strategies and recommendations to ensure that urban design applied to new and existing
development would be visually appealing and compatible with existing development and would
enhance connectivity throughout the City. While the visual character could change substantially
with implementation of the General Plan Update (e.g., infill development where no structures
currently exist; new mixed-use development on underutilized land), such changes are more likely
City of Fontana | Addendum to the General Plan FEIR for the
Community Mobility and Circulation Element Update
Addendum Finding 15
to be considered a beneficial aesthetic impact and an improvement to the views within the
Project area, rather than an adverse impact.
Policies and actions included in the Land Use, Zoning, and Urban Design Element, the Community
and Neighborhoods Element, and the Downtown Area Plan are consistent with the principles and
goals stated in the General Plan Update for those chapters. Additionally, urban design that will
shape the character of new construction for infill, redevelopment, and new development would
be guided by the policies and actions in the General Plan Update, as well as the City’s Zoning
and Development Code, which is required to be consistent with the City’s General Plan. Therefore,
implementation of development allowed under the General Plan Update was concluded to have
a less than significant impact on the existing visual character and quality of the Planning Area and
its surroundings.
Would the project create a new source of substantial light or glare which would adversely affect
day or nighttime views in the area?
Development under the General Plan will introduce new light sources in areas that were previously
vacant or underutilized, and additional sources of light in previously developed areas, including
exterior building and sign lighting, streetlights, transit shelter lighting, security lighting in parks and
on trails, and additional vehicle headlights. Future development projects would be required to
comply with existing City regulations to address light and glare impacts to adjacent properties.
For instance, Section 30.326 of the Fontana Municipal Code requires low-level security lighting for
all multiple-family residential common parking areas, and for all other uses anticipated to have
night-time activity. In addition, all lights must be directed and shielded to prevent light and glare
from spilling over onto adjacent properties (thereby avoiding an adverse effect), and lighting
design must be compatible with the architectural style of related buildings. With compliance with
the Fontana Municipal Code, the General Plan FEIR concluded that implementation of
development under the General Plan Update would result in less than significant impacts of light
and glare on day and nighttime views.
Analysis of Project
a. Would the project have a substantial adverse effect on a scenic vista?
b. Would the project substantially damage scenic resources, including, but not limited to,
trees, rock outcroppings, and historic buildings within a state scenic highway?
c. Would the project, 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 point). If the project is in an
urbanized area, would the project conflict with applicable zoning and other regulations
governing scenic quality?
d. Would the project create a new source of substantial light or glare which would adversely
affect day or nighttime views in the area?

Addendum Finding 16
The Project does not propose site-specific development; rather, it involves amendments to the
General Plan Community Mobility and Circulation Element to comply with AB 98 requirements
related to the City’s truck-route network. Specifically, the City’s existing Truck Route Map (Exhibit
9.7, Truck Routes) would be updated to shift truck traffic away from residential uses and sensitive
receptors, while also clarifying what facilities are officially part of the City-controlled local truck
route network. The Project also proposes minor text changes to existing policies and actions in the
City’s Community Mobility and Circulation Element, as well as the addition of new policies and
actions, to further address AB 98 requirements to provide specific truck route requirements and
avoid residential areas and sensitive receptors, as well as direct the City towards meeting other
AB 98 requirements.
The proposed Project would not result in any modifications to existing land use designations or
modify any existing roadways or roadway classifications or allow for any specific circulation system
projects or improvements. The Project would not modify any General Plan policies or programs
specific to visual resources.
As the Project does not propose any development, it would not obscure viewsheds to the San
Gabriel Mountains, Jurupa Hills, or other scenic resources, and would not result in a substantial
adverse effect on a scenic vista. Similarly, as the Project does not propose site-specific
development or modify any General Plan policies or programs specific to visual resources, the
Project would not substantially degrade the existing visual character or quality of public views of
a site and its surroundings or conflict with zoning and other regulations governing scenic quality.
As discussed in the General Plan FEIR, there are no officially designated or eligible scenic highways
within or adjacent to the City and as such, the Project would not substantially damage scenic
resources, including, but not limited to, trees, rock outcroppings, and historic buildings within a
state scenic highway.
While headlights and reflective materials associated with trucks traveling along the City’s truck-
route network would contribute to light and glare along designated truck routes, these sources of
light and glare already exist under existing conditions. The Project involves a citywide redistribution
of truck trips on City roadways; the Project would not create new truck trips within the City or
region and as such, the Project would not generate new sources of light and glare. Rather, the
Project is likely to have an overall beneficial impact by updating the City’s existing Truck Route
Map to shift truck traffic away from residential uses and sensitive receptors, thereby reducing the
potential for light and glare near sensitive receptors. Therefore, the Project would not create a
new source of substantial light or glare which would adversely affect day or nighttime views in the
area.
The General Plan includes goals, policies, and actions to protect the visual character of the City
and reduce potential impacts to scenic resources and to reduce impacts associated with light
and glare as a result of new development. The proposed amendments to the General Plan
Community Mobility and Circulation Element would not conflict with implementation of these
General Plan goals, policies, or actions or the General Plan FEIR mitigation measures.

The City’s Resource Area (OS-R) zoning district includes agricultural land, which accounts for
approximately 332 acres (less than 2 percent) of the Project area. No portion of the City is
designated or zoned as forest land or timberland. Therefore, the General Plan FEIR concludes that
implementation of the General Plan would not result in impacts to agriculture or forestry resources.

General Plan FEIR Conclusions
Would the project conflict with or obstruct implementation of the applicable air quality plan?
As a policy document, no development is authorized or would directly occur from the adoption
of the General Plan Update. However, development can be expected to occur within the
planning area guided by General Plan policies.
Pursuant to the methodology provided in Chapter 12 of the 1993 SCAQMD CEQA Air Quality
Handbook, consistency with the 2016 AQMP is affirmed when a project: (1) does not increase the
frequency or severity of an air quality standards violation or cause a new violation and (2) is
consistent with the growth assumptions in the AQMP(SCAQMD).
Criterion 1. Air quality modelling is typically undertaken to determine if a specific project could
cause a violation of any air quality standard either regionally or locally. However, given that the
General Plan Update represents a programmatic proposal and would not directly result in
construction of any development or infrastructure, such analysis was not conducted as part of the
environmental impact analysis. As discussed in the General Plan FEIR, future developments that
result from buildout of the General Plan Update would be subject to CEQA.
Criterion 2. With implementation of the General Plan Update, the City of Fontana planning area
is estimated to grow to a total population of 315,852, which is an approximately 12% increase
City of Fontana | Addendum to the General Plan FEIR for the
Community Mobility and Circulation Element Update
Addendum Finding 21
compared to the population forecast assumed in the RTP/SCS and has the potential to be
inconsistent with the 2016 AQMP. However, the land use modifications and policies proposed as
part of the General Plan Update would result in an approximately 19% reduction in per capita
vehicle miles traveled compared to 2040 buildout of the 2003 General Plan. Despite the projected
population growth (including employment) associated with the General Plan Update, daily total
vehicle miles traveled within the General Plan Planning Area would be reduced by approximately
9%. The emissions inventory in the 2016 AQMP demonstrates that mobile source vehicle emissions
represents the single largest category and approximately 56% of all emissions in the South Coast
Air Basin (SCAB). As a result, the 9% reduction in daily total vehicle miles traveled under buildout
for the General Plan Update would have a substantial reduction in mobile source vehicle
emissions which are the single largest contributor of criteria air pollutants in the SCAB.
While implementation of the General Plan Update would result in projected population growth
that exceeds the population estimates considered in the RTP/SCS, a considerable reduction of
per capita (25%) and total (9%) criteria air pollutant emissions would occur compared to existing
conditions. These emissions reductions would occur as a result of the land use modifications and
policies that would substantially decrease vehicle miles travelled within the City. The reduction in
emissions from General Plan Update implementation would be achieved despite the projected
population growth. Because the projected population growth would result in considerably fewer
emissions than those considered for the City of Fontana population in the SCAQMD’s AQMP, the
General Plan FEIR concluded that implementation of the General Plan Update would be
consistent with the AQMP and impacts would be less than significant.
Would the Project violate any air quality standard or contribute substantially to an existing or
projected air quality violation?
Short-term Impacts. The General Plan Update has the potential to result in 33,454 acres of land use
compared to 33,428 acres of land use from the current 2003 General Plan. Overall, this represents
a negligible difference (0.07%). Some building demolition and construction would be expected
to occur as a result of land use modifications included in the General Plan Update such as
changing some commercial land uses to walkable mixed use land uses. These construction
activities would not all occur simultaneously but would rather be spread over the General Plan
Update’s 20-year build-out schedule.
Pursuant to existing CEQA requirements, short-term, project-specific construction-related emissions
will be analyzed as development proposals are submitted. Mitigation will be applied, where
necessary, and typically includes requirements for use of low-VOC paints, installation of diesel
particulate filters on older construction equipment, and limitations on hauling distances and daily
trips.
Long-term Impacts. Operational emissions from area, energy, mobile, and point sources were
estimated in CalEEMod 2016.3.1 for the land use mix proposed under the General Plan Update.
Compared to the 2003 General Plan, it is estimated that all criteria pollutants from the General
Plan Update would decrease overall with the exception of PM2.5. However, the estimated increase
City of Fontana | Addendum to the General Plan FEIR for the
Community Mobility and Circulation Element Update
Addendum Finding 22
of 6.28 pounds per day PM2.5 emissions are below the applicable SCAQMD threshold of
significance of 55 pounds per day. The estimates also show a substantial reduction in emissions
associated with the reduction in vehicle miles traveled achieved by the proposed goals and
policies of the General Plan Update. The General Plan Update would therefore not violate any air
quality standard or contribute substantially to an existing or projected air quality violation. The
General Plan FEIR concluded potential impacts would be less than significant.
Would the project 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?
Compared to the 2003 General Plan, the General Plan reduces long term criteria pollutant
emissions overall, with the exception of PM2.5, which increases by about 6.28 pounds per day, a
level well below SCAQMD’s 55 pounds per day threshold. With supporting General Plan policies
that reduce vehicle miles traveled and improve transportation efficiency, the General Plan FEIR
concluded the General Plan would not result in a cumulatively considerable net increase of
criteria pollutants, and potential impacts would therefore be less than significant.
Would the project expose sensitive receptors to substantial pollutant concentrations?
Concentrations of Criteria Pollutants
Future development associated with buildout of the General Plan would be required to prepare
an air quality impact analysis for individual development projects where possible emissions could
impact sensitive receptors. Such analyses would include project-specific mitigation measures, as
appropriate. As well, future construction activities will be subject to routine control measures as
required by SCAQMD (Rules 402, 403, 1108, and 1113). It should be noted that SCAQMD guidance
indicates that analysis of localized criteria pollutant impacts is required; therefore, future
construction projects would be assessed for localized criteria pollutant impacts on a case-by-case
basis under the purview of the City.
According to the Air Quality and Land Use Handbook, the California Air Resources Board (CARB)
recommends that sensitive land uses are not located within 500 feet of highways or major arterials
having average annual daily traffic (AADT) that exceeds 100,000 vehicles. This is due to the
concentration of pollutants that accumulate in this proximity to freeways and other major arterials.
There are no non-freeway roadways in the General Plan Planning Area that are projected to have
an AADT that exceeds 100,000 vehicles; however, there are three major freeways in the General
Plan Planning Area (I-10, I-15, and SR-210) that do exceed the 100,000 vehicles. Based on CARB
guidelines, a significant impact could occur if the General Plan Updates would permit new
residential or other sensitive uses within 500 feet of these highways. Under existing conditions,
residential land uses exist within 500 feet of these highways within the General Plan Planning Area.
Also, there are a number of vacant parcels designated for residential land use within 500 feet of
either freeway. However, the General Plan Update does not propose new sensitive land uses
within 500 feet of I-10, I-15, or SR-210.
City of Fontana | Addendum to the General Plan FEIR for the
Community Mobility and Circulation Element Update
Addendum Finding 23
As shown in the General Plan FEIR, the General Plan Update would not substantially degrade the
existing Levels of Service at the most potentially affected intersections in the City. As a result, the
General Plan Update would not be expected to create a CO hotspot or contribute to a
substantial increase in existing CO concentrations at intersections with poor Levels of Service.
Pursuant to existing regulations, future development projects associated with buildout of the
General Plan Update will be screened and analyzed pursuant to the CO Protocol to determine if
a CO hotspot may occur at congested intersections. Mitigation may be required, if necessary, to
alleviate traffic congestion and minimize the hotspot potential. Other mitigation could include
operational restrictions on future development. With screening and analysis of future projects
pursuant to the CO Protocol, the General Plan FEIR concluded impacts related to carbon
monoxide hotspots would be less than significant.
With the implementation of General Plan Update policies and adherence to existing
environmental regulations that require specific analysis of impacts of industrial projects on sensitive
receptors, the General Plan FEIR concluded that the General Plan Update would not expose
sensitive receptors to substantial criteria air pollutant concentrations and potential impacts would
be less than significant.
Toxic Air Contaminants
The General Plan Update could result in the addition of 377 acres of new industrial land use
compared to the 2003 General Plan. However, as identified in the Land Use, Zoning, and Urban
Design Element of the General Plan Update, the heaviest industrial land uses, which most
commonly contribute to toxic air contaminants, are concentrated in the southwest corner of the
City in areas designated for industrial development and away from sensitive receptors, such as
residential areas. The City also has policies restricting the location of residences near heavy
industrial areas. The General Plan FEIR concluded that the General Plan Update would therefore
not expose sensitive receptors to substantial toxic air contaminants. Impacts would be less than
significant.
Would the project result in other emissions (such as those leading to odors) adversely affecting a
substantial number of people?
Odor-generating uses are typically agricultural operations, wastewater treatment plants, landfills,
and certain industrial activities. In Fontana, the heaviest industrial land uses, which most commonly
contribute to odors, are concentrated in the southwest corner of the City in areas designated for
industrial development and away from sensitive receptors, such as residential areas. The City also
has policies restricting the location of residences near heavy industrial areas. According to the
General Plan FEIR, future projects would be reviewed case by case, with siting as the primary
avoidance measure and additional mitigation such as filtration if needed. Therefore, the General
Plan FEIR concluded that impacts related to odors would be less than significant with
implementation of existing development review practices.

Analysis of Project
a. Would the project conflict with or obstruct implementation of the applicable air quality
plan?
Pursuant to the methodology provided in Chapter 12 of the 1993 SCAQMD CEQA Air Quality
Handbook, consistency with the 2016 AQMP is affirmed when a project: (1) does not increase the
frequency or severity of an air quality standards violation or cause a new violation and (2) is
consistent with the growth assumptions in the AQMP.
Criterion 1. The purpose of the redistribution of truck travel required under AB 98 has the goal of
improving air quality at sensitive land uses. Consequently, the Project does not involve the
development of land uses or roadways that would promote population growth within the City.
However, the Project was assessed relative to changes in air pollutant emissions associated with
vehicle trips and Vehicle Miles Travelled (VMT). The potential for air quality impacts associated
with vehicular emissions occurs on both a local and regional level. Redistribution of diesel-fueled
vehicles would reduce the exposure of air toxics, such as diesel exhaust, from sensitive land uses
consistent with the goal of AB 98. The increase in diesel exhaust emissions along truck routes
designated under AB 98 was evaluated below relative to increases in health risk along the
proposed transportation corridors. It found that the transportation corridors with the three highest
truck volumes and highest potential for diesel related health risk due to the proposed Project
would result in health risk levels that are below the SCAQMD’s significance thresholds for acute,
chronic, and cancer. The Project was analyzed and found that it would also not result in significant
increases in other localized pollutants such as carbon monoxide and odors. As such, localized air
pollutants due to the Project would result in less than significant air quality impacts at corridors
where trucks would be relocated under AB 98. Areas where there would be less truck traffic
attributable to the Project would experience less truck related exhaust emissions and would
consequentially experience a beneficial impact on localized air quality.
In terms of regional air quality, the changes to the truck routes under the Project would result in
changes to VMT. According to the Traffic Memorandum prepared for the proposed Project
(Kittelson & Associates, 2025), the Project would increase truck VMT by approximately 797 VMT
under future Project conditions as compared to future No Project conditions. This increase in VMT
represents a 0.02 percent change in total VMT resulting from the Project and would result in
increases in vehicular emissions which are substantially below the SCAQMD’s operations phase
CEQA thresholds as analyzed in the impact analysis below. Because the Project would not exceed
the SCAQMD’s localized or regional significance thresholds, the Project would not result in a
significant impact related to increasing the frequency or severity of an air quality standards
violation or cause a new violation.
Criterion 2. The second criterion involves whether the Project is consistent with the growth
assumptions in the 2022 AQMP. The Project would not change land use development within the
City. There also would not be a change in vehicular trip generation within the City. In addition, the
VMT increase associated with the Project would result in a 0.02 percent increase which is not

Community Mobility and Circulation Element Update
Addendum Finding 25
considered to be a substantial increase in truck travel within the City. Consequently, the Project
would not result in substantial growth in vehicle use compared to the assumptions used in the 2022
AQMP. Additionally, the Project is consistent with the land use planning strategies set forth in the
AQMP relative to reducing the exposure of sensitive land uses to air pollutant concentrations.
Potential impacts related to the Project would therefore be less than significant.
Because the Project would not exceed either Criterion 1 nor Criterion 2, the Project would not
conflict with or obstruct implementation of the 2022 AQMP and would result in less than significant
air quality impacts.
b. Would the project 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?
The SCAQMD has developed significance thresholds for both construction and operations phase
activities.
Short-Term Construction Emissions Impacts
The Project does not propose the development of roadway infrastructure nor involve any
construction activities. Consequently, the Project does not involve construction related emissions.
As such, there would be no impact related to Project related construction emissions.
Long-Term Operational Emissions Impacts
The Project’s operational emissions would be associated with trucks travelling within the City. The
change in truck emissions are related to changes in the amount of vehicle trips or changes in the
VMT. As discussed previously, the Project does not involve the development of land uses or
roadways that would promote new vehicle trip growth or changes in vehicle trips within the City.
As such, the Project would not result in additional truck trips and associated emissions beyond
those that are currently occurring or projected to occur in the City.
Truck related VMT is estimated to be 4,733,518 miles within the City under future conditions without
the Project. The Project’s redistribution of truck trips will increase VMT by 797 miles under future
Project conditions and result in a total of 4,734,315 miles (Kittelson & Associates, 2025). This increase
in VMT represents a 0.02 percent change in total VMT resulting from the Project. To calculate the
emissions associated with the increase in VMT, truck emissions associated with VMT were
calculated based on emission rates calculated with the California Air Resources Board’s EMFAC
emission factor model. EMFAC2025 was used to calculate emission rates based on heavy-duty
trucks within San Bernardino for the year 2040. Calculation sheets for these emissions are provided
in Appendix A. The EMFAC2025 estimated emissions from the change in VMT of 797 miles
attributable to Project operations are summarized in Table 1, Truck-Related Emissions (Maximum
Pounds Per Day).

As shown in Table 1, emission calculations generated from CalEEMod demonstrate that Project
operations would not exceed the South Coast AQMD thresholds for any criteria air pollutants.
Therefore, Project cumulative operational impacts would be less than significant.
c. Would the project expose sensitive receptors to substantial pollutant concentrations?
Localized Construction Significance Analysis
As discussed previously, the Project would not involve construction activities and consequently
would not generate construction related emissions. As such, there would not be localized
construction emissions and would have no impact related to localized construction emissions.
Localized Operational Significance Analysis
The SCAQMD has developed Localized Significance Thresholds (LSTs) to assess the potential for
projects to create localized air quality impacts during operations. LSTs provide screening-level
thresholds for criteria pollutants—nitrogen oxides (NOx), carbon monoxide (CO), coarse
particulate matter (PM10), and fine particulate matter (PM2.5)—to determine whether emissions
from a project could cause or contribute to exceedances of ambient air quality standards at
nearby sensitive receptors such as residences, schools, or hospitals. LSTs are typically applied to
on-site operational sources, such as parking/loading areas, stationary and area emissions, for
proposed land uses but do not include off-site vehicle trips.
Since the Project involves a citywide redistribution of truck trips on City roadways, the use of the
SCAQMD’s LSTs do not apply. According to assessment methods established by the SCAQMD,
vehicular emissions are best assessed based on an analysis of carbon monoxide “hot spots” and
whether the proposed Project would have the potential to result in exceedances of the California
Ambient Air Quality Standards or National Ambient Air Quality Standards. It has long been
recognized that carbon monoxide exceedances are caused by vehicular emissions, primarily
when vehicles are idling at intersections. Vehicle emissions standards have become increasingly
stringent in the last 20 years. With the turnover of more polluting older vehicles, introduction of
cleaner fuels, and implementation of control technology from the use of catalytic converters,
City of Fontana | Addendum to the General Plan FEIR for the
Community Mobility and Circulation Element Update
Addendum Finding 27
carbon monoxide concentrations have steadily declined. The South Coast Air Basin has been in
a state of attainment of the California and National ambient air quality standards for CO for
approximately two decades. Many air pollutant monitoring stations are no longer measuring CO
due to low concentration levels of this pollutant. Accordingly, with the steadily decreasing carbon
monoxide emissions from vehicles, even very busy intersections do not result in exceedances of
the carbon monoxide standard.
The 2022 AQMP is the most recent version that addresses carbon monoxide concentrations. As
part of the South Coast AQMD Carbon Monoxide Hotspot Analysis, the Wilshire Boulevard/Veteran
Avenue intersection, one of the most congested intersections in Southern California with
approximately 100,000 average daily traffic (ADT), was modeled for carbon monoxide
concentrations. This modeling effort identified a carbon monoxide concentration high of 4.6 ppm,
which is well below the 35-ppm 1-hour Federal standard and 20-ppm California 1-hour CO
standard. The proposed Project would not result in a redistribution of truck traffic volumes required
to generate a carbon monoxide hot spot in the context of the South Coast AQMD’s Carbon
Monoxide Hotspot Analysis. Under existing conditions, the roadway segment of Cherry between
Valley and Slover has the highest traffic volumes for local roadways and results in 46,999 ADT
(Kittelson & Associates, 2025). Additional vehicle trips for intersections along that roadway
segment results in vehicle trips of less than the 100,000 ADT referenced in the AQMP. As excessive
carbon monoxide hotspots were not experienced at the Wilshire Boulevard/Veteran Avenue
intersection even as it accommodates 100,000 ADT, it can be reasonably inferred that carbon
monoxide hotspots would not occur at any Project area intersections since local roadways within
the City would not exceed 100,000 ADT. There are freeway segments within the City that exceed
100,000 ADT but the nearest residential uses are located at least 100 feet from the nearest
centerline of the freeway segment. This distance allows for dispersion of roadway air pollutants. In
addition, SCAQMD carbon monoxide measurements near the 10 freeway for monitoring area of
Fontana shows CO concentrations of 1.5 ppm for 1-hour concentrations and 1.1 ppm for 8-hour
concentrations (SCAQMD 2025). This is a small fraction of the State and federal ambient air quality
standards for carbon monoxide. Lastly, the State of California’s vehicle fleet is increasingly
transitioning to hybrid, fuel cell, or electric vehicles which results in little or no idling emissions.
Therefore, potential impacts related to CO hotspots attributable to the Project would be less than
significant.
Diesel emissions from trucks are a key concern in air quality assessments because Diesel particulate
matter (DPM) is classified by the California Air Resources Board (CARB) as a toxic air contaminant
due to its strong links to respiratory illness, cardiovascular disease, and increased cancer risk. As a
result, evaluating diesel emissions from truck operations is an important part of both health risk
assessment and localized air quality impact analysis. Diesel particulate matter emissions are often
quantified for use in health risk assessments, which estimate potential cancer and non-cancer
health risks for sensitive receptors.
Heavy-duty trucks are a common source of DPM, in contrast to passenger vehicles (such as light-
duty cars and trucks). The inhalation of DPM generates cancer and non-cancer health risks,

Community Mobility and Circulation Element Update
Addendum Finding 28
especially where concentrations are elevated for long periods of time and for younger sensitive
receptors. The Office of Environmental Health Hazards Assessment (OEHHA) includes procedures
for evaluating hazardous air pollutants. Based on the guidance provided by OEHHA, an air toxics
health impact analysis has been prepared to analyze whether the proposed truck route map,
which would result in changes to truck travel within the City, would result in an impact from diesel
exhaust emitted by heavy-duty trucks.
An air toxics health risk assessment was conducted utilizing Lakes Environmental Software AERMOD
and the CARB’s Hotspots Analysis Reporting Program Version 2 (HARP 2) Air Dispersion, Modelling,
and Risk Tool (ADMRT) for the DPM associated with the heavy-duty trucks. Emissions associated
with the change in truck travel due to the Project were calculated. The three roadway segments
that would have the highest change in truck VMT due to the Project were selected for analysis.
The maximum residential (70-year exposure) cancer, chronic (non-cancer), and acute (non-
cancer) risks were assessed and compared to SCAQMD thresholds. OEHHA does not consider
DPM to result in health effects from acute exposure. Table 2, Truck-Related Health Risks, presents
the results of the analysis. Refer to Appendix A for model inputs.
Table 2
Truck-Related Health Risks
Analysis Locations Cancer Risk
per Million Chronic Risk Acute Risk
210 Freeway – 15 Freeway to Citrus Avenue 3 <0.1 0
Citrus Avenue - Baseline Avenue to Foothill Boulevard 1 <0.1 0
Foothill (Citrus Avenue -Sierra Avenue) 2 <0.1 0
Significance Threshold 10 1 1
Exceeds Threshold? No No No
Sources: AERMOD 11.2.0 and HARP-2 Air Dispersion and Risk Tool (version 22118); refer to Appendix A for
model outputs.
As shown in Table 2, the Project would result in health risks for cancer, chronic, and acute
exposures that are less than the SCAQMD’s significance thresholds. In addition, the Project would
not result in carbon monoxide hotspots. As such, the Project would result in less than significant
impacts related to localized health risks.
d. Would the project result in other emissions (such as those leading to odors) adversely
affecting a substantial number of people?
Heavy-duty trucks can generate odorous diesel particulate matter with the potential to adversely
affect nearby sensitive receptors. As the Project would not create new truck trips within the City
or region, the Project would not generate new opportunities for activities that would emit
objectionable odors affecting substantial numbers of people beyond existing conditions. Rather,
the Project is likely to have an overall beneficial impact by updating the City’s existing Truck Route
Map to shift truck traffic away from residential uses and sensitive receptors, thereby reducing the
potential for exposure. As such, the Project would not result in new significant impacts or a

substantial increase in the severity of previously identified significant impacts relative to other
emissions such as odors.
Conclusion
The Project would not result in new or greater air quality impacts beyond those identified in the
General Plan FEIR.
Applicable General Plan FEIR Mitigation Measures: No mitigation measures are required.

General Plan FEIR Conclusions
Would the project have a substantial adverse effect, either directly or through habitat
modifications, on any species identified as a candidate, sensitive, or special status species in local
or regional plans, policies, or regulations, or by the CDFW or USFWS?
The northern and southern portions of the City have the most potential to support habitat suitable
for special status species due to the presence of open space along the foothills of the San Gabriel
Mountains and in the Jurupa Hills. Except for the burrowing owl and nesting raptors or passerine
birds, no special status species have the reasonable potential to occupy lands that are subject to
the General Plan land use changes.
One species of concern that is known to occur in areas that may be affected by the General Plan
Update is the burrowing owl. This species is known to nest in existing burrows, culverts, or other
appropriately-sized holes on disturbed, vacant, or agricultural lands. Therefore, it could
theoretically inhabit any such land in the General Plan Planning Area. Any future development of
these types of areas could potentially impact this species. The General Plan FEIR concludes that
implementation of MM-BIO-1 would reduce the potential impacts to burrowing owls to a less than
significant level.
The General Plan Planning Area also supports a wide variety of potential nesting habitat for raptors
and passerines. Nesting birds can be adversely affected from noise or human activity generated
during construction, resulting in decreased reproductive success or abandonment of a nest or an
area defined as nesting habitat. Any future development within the General Plan Planning Area
that resulted in such adverse effects may be considered in violation of the MBTA, which would be
considered a significant impact. The General Plan FEIR concludes that implementation of MM-
BIO-2 would reduce the potential impacts to nesting birds to a less than significant level.
Would the project have a substantial adverse effect on any riparian habitat or other sensitive
natural community identified in local or regional plans, policies, regulations, or by the CDFW or
USFWS?
The CNDDB identified five sensitive natural communities within the General Plan Planning Area:
California Walnut Woodland, Coastal and Valley Freshwater Marsh, Riversidean alluvial fan sage
scrub (RAFSS), Southern Riparian Forest, and Southern Sycamore Alder Riparian Woodland. These
communities and remaining natural riparian habitat all occur within portions of the San Gabriel
Mountains foothills and Jurupa Hills to the north and south of the City, respectively. Temporary or
permanent impacts to these habitats would have a significant impact. However, the General Plan
FEIR concluded that Goal 1 of the General Plan governing Conservation, Open Space, Parks, and
Trails will protect these areas; therefore, no impact to these sensitive habitats would occur.
City of Fontana | Addendum to the General Plan FEIR for the

Addendum Finding 32
Would the project have a substantial adverse effect on federally protected wetlands as defined
by Section 404 of the Clean Water Act (including, but not limited to, marsh, vernal pool, coastal,
etc.) through direct removal, filling, hydrological interruption, or other means?
Temporary or permanent impacts to federally protected wetlands as defined by Section 404 of
the Clean Water Act (CWA) would have a significant impact. However, based on a review of the
USFWS’ National Wetlands Inventory online mapper and surveys conducted, no wetlands located
within the General Plan Planning Area are subject to land use changes. Therefore, the General
Plan FEIR concluded that implementation of the General Plan Update would not impact any
wetlands as defined by Section 404 of the CWA.
Would the project interfere substantially with the movement of any native resident or migratory fish
or wildlife species or with established native resident or migratory wildlife corridors, or impede the
use of native wildlife nursery sites?
Due to development of the valley floor and surrounding the Jurupa Hills, wildlife movement within
the General Plan Planning Area is limited to an east-west orientation along the foothills of the San
Gabriel Mountains north of I-15. Temporary or permanent impacts to such areas as described in
Table 5.3-3 of the General Plan FEIR would have a significant impact. However, this area will be
protected by Goal 1 of the General Plan Update governing Conservation, Open Space, Parks,
and Trails and are not subject to land use changes. Therefore, the General Plan FEIR concluded
that no impacts would occur.
Would the project conflict with any local policies or ordinances protecting biological resources,
such as a tree preservation policy or ordinance?
Development allowed by the updated General Plan would be required to comply with General
Plan policies and existing City policies related to the protection of biological resources. As a result,
the General Plan FEIR concluded the General Plan Update would not conflict with any City
policies, regulations, or standards designed to protect biological resources.
Would the project conflict with the provisions of an adopted Habitat Conservation Program (HCP),
Natural Community Conservation Plan (NCCP), or other approved local, regional, or state habitat
conservation plan?
No formal HCP exists that includes the General Plan Planning Area. However, in 2004, the City
commissioned the preparation of a MSHCP to address potential impacts to sensitive RAFSS and
RSS habitats and special status species that may occur within the North Fontana Conservation
Program Area in the San Gabriel Mountains foothills. To enforce the intent of the MSHCP during
the period of time required for its preparation and adoption, the City Council approved City
Ordnance No. 1464 on December 7, 2004. This ordinance established a tiered mitigation fee
program for development within the subject area.
Goal 1 of the General Plan Update governing Conservation, Open Space, Parks, and Trails will
protect the area encompassed within the North Fontana Conservation Program Area. In addition,
City of Fontana | Addendum to the General Plan FEIR for the
Community Mobility and Circulation Element Update
Addendum Finding 33
the ordinance stipulates that the payment of mitigation fees pursuant to the policy shall not apply
to the adoption or amendment of the City’s General Plan; therefore, the General Plan FEIR
concluded no impact would occur.
As discussed in Section 5.9.3 of the General Plan FEIR, none of the land use changes proposed in
the General Plan Update would conflict with the North Fontana Conservation Program since no
land use changes are proposed in affected areas nor has the City adopted a Multiple Species
Habitat Conservation Plan. Therefore, impacts would be less than significant.
Analysis of Project
a. Would the project 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

The Project does not propose site-specific development; rather, it involves amendments to the
General Plan Community Mobility and Circulation Element to comply with AB 98 requirements
related to the City’s truck-route network. Specifically, the City’s existing Truck Route Map (Exhibit
9.7, Truck Routes) would be updated to shift truck traffic away from residential uses and sensitive
receptors, while also clarifying what facilities are officially part of the City-controlled local truck
route network. The Project also proposes minor text changes to existing policies and actions in the
City’s Community Mobility and Circulation Element, as well as the addition of new policies and
actions, to further address AB 98 requirements to provide specific truck route requirements and
avoid residential areas and sensitive receptors, as well as direct the City towards meeting other
AB 98 requirements.

specific to biological resources.
The Project does not propose any development and proposed changes to the City’s truck-route
network would occur within the rights-of-way of existing local roadways. Further, the Project
involves a citywide redistribution of truck trips on City roadways; the Project would not create new
truck trips within the City or region. As such, the Project would not have a substantial adverse
effect on any candidate, sensitive, or special-status species; would not have the potential to
directly or indirectly impact riparian habitat or other sensitive natural communities; and would not
impact federally protected wetlands.
As discussed in the General Plan FEIR, due to development of the valley floor and surrounding the
Jurupa Hills, wildlife movement within Fontana is limited to an east-west orientation along the
foothills of the San Gabriel Mountains north of I-15. The Project does not propose to designate any
roadway segments north of I-15 as truck routes. As such, the Project would not interfere
substantially with the movement of any native resident or migratory fish or wildlife species or with
established native resident or migratory wildlife corridors, or impede the use of native wildlife
nursery sites, resulting in new or greater impacts beyond those identified in the General Plan FEIR.
The Project does not propose site-specific development or modify any General Plan policies or

regulations, or standards designed to protect biological resources. Further, as discussed in the
General Plan FEIR, the City has not adopted a Multiple Species Habitat Conservation Plan. The
Project does not propose to designate any roadway segments within the North Fontana
Conservation Program Area. Therefore, the Project would not conflict with the provisions of an
adopted Habitat Conservation Program, Natural Community Conservation Plan, or other
approved local, regional, or state habitat conservation plan.
The General Plan includes goals, policies, and actions to preserve open space and protect
biological resources. The proposed amendments to the General Plan Community Mobility and
Circulation Element would not conflict with implementation of these General Plan goals, policies,
or actions or the General Plan FEIR mitigation measures.
Conclusion
The Project would not result in new or greater biological resources impacts beyond those identified
in the General Plan FEIR.

The City certified the General Plan FEIR before CEQA Guidelines Appendix G was revised to
address paleontological resources within Section 3.7, Geology and Soils and to address tribal
cultural resources within Section 3.18, Tribal Cultural Resources. For purposes of this analysis, the
topics of paleontological resources and tribal cultural resources are discussed below, consistent
with the General Plan FEIR.
General Plan FEIR Conclusions
Would the project cause a substantial adverse change in the significance of a historical or
archeological resource pursuant to § 15064.5?
As discussed in the General Plan FEIR, development implemented under the General Plan Update
could potentially affect known or unknown cultural and/or paleontological resources. However,
effects on cultural resources can only be addressed after a project has been proposed because
the effects are dependent on location, site conditions, and project development characteristics
(e.g., depth of ground disturbances). Therefore, the General Plan FEIR states that potential
impacts that could destroy or damage cultural resources as a result of development under the
General Plan Update are too speculative to assess at this time. Consequently, each project and
the potential impacts will be assessed by the City at the time of a development proposal.
The General Plan includes goals, policies, and actions that align with Article XIII of the Fontana
Municipal Code, Preservation of Historic Resources. Future development projects will be subject
to applicable regulations in City Municipal Code dealing with cultural resources as well as federal
and state cultural resources laws and regulations. Therefore, the General Plan FEIR concluded that
the General Plan Update will result in a less than significant impact to cultural resources.
City of Fontana | Addendum to the General Plan FEIR for the

Would the project cause a substantial adverse change to the significance of a Tribal Cultural
Resources as defined in Public Resources Code section 21074
(site/feature/place/landscape/sacred place of object) that holds cultural or religious value to a
California Native American Tribe?
The City is required to comply with AB 52 and SB 18 dealing with Tribal Cultural Resources. These
laws require the City to consult with Native American Tribes to determine their interest in future
projects located within the City. General Plan Update goals, policies, and actions are consistent
with the requirements of AB 52 and SB 18 and Goal 3: Cultural and archaeological resources are
protected and preserved reinforces the City’s commitment to the preservation of cultural and
archaeological resources, including Tribal Cultural Resources. Therefore, the General Plan FEIR
concluded that the General Plan Update will not cause significant impacts to Tribal Cultural
Resources.
Would the project directly or indirectly destroy a unique paleontological resource or site or unique
geologic feature?
As discussed in the General Plan FEIR, no specific development project is part of the General Plan
Update and future projects will undergo environmental and development review at the time of a
development application. The project would be assessed for the potential to impact
paleontological resources based on the location of the project with respect to the sensitivity of
the underlying geologic formations to contain fossils as well as the depth of excavation of the
facilities associated with the project. Therefore, it is speculative to evaluate impacts of future
projects on paleontological resources. The General Plan FEIR concluded that the General Plan
Update goals, policies, and actions commit the City to preserve and protect significant historic
and cultural resources. Therefore, no significant impacts will result to paleontological resources
from the General Plan Update goals, policies, and actions.
Would the project disturb any human remains, including those interred outside of formal
cemeteries?
Potential impacts to human remains, like impacts to historic or archaeological resources, are
dependent on the location and nature of the project such as excavation for project features.
According to the General Plan FEIR, future projects will be subject to environmental review by the
City and subject to federal and state law regarding disturbance of human remains. Because no
site-specific work is authorized by the General Plan Update, evaluating such impacts now would
be speculative. The General Plan’s goals, policies, and actions commit the City to preserve and
protect significant historic and cultural resources. Therefore, the General Plan FEIR concluded that
no significant impacts would result to human remains from the General Plan Update goals,
policies, and actions.

The General Plan FEIR does not include a stand-alone Energy analysis section. The City certified
the FEIR before CEQA Appendix G was revised to add a specific Energy checklist item. However,
the topic of energy is addressed in General Plan FEIR Section 7.6, Energy Conservation.
General Plan FEIR Conclusions
Approval and implementation of actions related to the General Plan Update would result in an
irretrievable commitment of nonrenewable resources, such as energy supplies and other
construction-related resources. The energy resource demands would be used for construction,
heating and cooling of buildings, transportation of people and goods from the City, heating and
refrigeration for food preparation and water, as well as lighting and other associated energy
needs.
Nonrenewable resources would be committed primarily in the form of fossil fuels and would
include fuel, oil, natural gas, and gasoline used by vehicles and equipment associated with
implementation of the General Plan Update. Since alternative energy sources such as solar or
wind energy are not currently in widespread local use, it is unlikely that real savings in non-
renewable energy supplies (i.e., oil and gas) could be realized in the immediate future.
Analysis of Project
a. Would the project result in potentially significant environmental impact due to wasteful,
inefficient, or unnecessary consumption of energy resources, during project construction
or operation?
The Project would result in a redistribution of truck trips to reduce environmental effects to
residential uses and other sensitive land uses. This redistribution of trips would reduce the exposure
of air and noise pollution to sensitive land uses. The change in truck routing would result in an
City of Fontana | Addendum to the General Plan FEIR for the

Addendum Finding 40
increase of 797 VMT which represents an increase in fuel usage of approximately 0.02 percent
(Kittelson & Associates, 2025). This is a nominal increase in fuel consumption to support the
environmental and health benefits associated with the proposed Project. As such, the Project
would result in a less than significant environmental impact due to wasteful, inefficient, or
unnecessary consumption of energy resources.
b. Would the project conflict with or obstruct a state or local plan for renewable energy or
energy efficiency?
The Project does not propose site-specific development; rather, it involves amendments to the
General Plan Community Mobility and Circulation Element to comply with AB 98 requirements
related to the City’s truck-route network. Specifically, the City’s existing Truck Route Map (Exhibit
9.7, Truck Routes) would be updated to shift truck traffic away from residential uses and sensitive

City’s Community Mobility and Circulation Element, as well as the addition of new policies and
actions, to further address AB 98 requirements to provide specific truck route requirements and
avoid residential areas and sensitive receptors, as well as direct the City towards meeting other
AB 98 requirements.
The proposed Project would not result in any modifications to existing land use designations or
modify any existing roadways or roadway classifications or allow for any specific circulation system
projects or improvements. Further, the Project would not create new truck trips within the City or
region; rather, the updates to the Truck Route Map would identify specific routes existing trucks
within the City would be required to utilize when traveling within the City. The nominal increase in
VMT and associated fuel consumption attributable to the Project would also not conflict with
energy efficiency. As such, the proposed amendments to the General Plan Community Mobility
and Circulation Element would not conflict with implementation of General Plan goals, policies,
or actions related to energy efficiency and resource conservation.
Conclusion
The Project would not result in new or greater energy impacts beyond those identified in the
General Plan FEIR.

General Plan FEIR Conclusions
Would the project create a significant hazard to the public or the environment through the
exposure of people or structures to potential substantial adverse effects involving risk of loss, injury
or death involving rupture of a known earthquake fault or strong seismic shaking or seismic-related
ground failure or landslides? Or result in substantial soil erosion?
City of Fontana | Addendum to the General Plan FEIR for the
Community Mobility and Circulation Element Update
Addendum Finding 42
As discussed in the General Plan FEIR, new and existing development would be subject to
earthquakes that could damage facilities and/or affect reliable use of facilities, including faults
identified on the Alquist-Priolo Earthquake Fault Zoning Map. Primary earthquake hazards include
damage from ground displacement along a fault zone, severe ground shaking, and induced
secondary hazards such as liquefaction in areas that are underlain by unconsolidated alluvial
deposits, seismically induced differential settlement, lurching, landslides, and rockfalls. In addition,
as groundshaking hazards are near surface phenomena, pipelines and other infrastructure are
particularly susceptible to damage. Damage or rupture of pipelines during a seismic event could
result in underground and surface release of water, which could result in localized flooding,
erosion, liquefaction, differential settlement, and lateral spreading.
Compliance with federal, state, county, and local regulations relating to the geologic hazards
would reduce the potential risk of potential impacts from geologic hazards to a less than
significant level. Furthermore, adherence to the mitigation program included in the City’s Local
Hazard Mitigation Plan (LHMP) to protect life, property and the environment would further reduce
potential impacts relative to geologic resources and geologic hazards.
Because the City is in Seismic Zone 4 of the 2016 California Building Code (CBC), structures would
be designed in accordance with parameters given within Chapter 16 of the current CBC. In
addition, as required by CBC Chapter 16, Division IV for the construction of new buildings and/or
structures, specific engineering design and construction measures would be implemented to
anticipate and avoid the potential for adverse impacts to human life and property caused by
seismically induced groundshaking. Thus, the majority of earthquake-related hazards would be
minimized by engineering design, compliance with local, state, and/or federal regulations
pertaining to geological hazards, or avoidance of high hazard areas. As such the General Plan
FEIR concluded that the General Plan Update would not create a significant hazard to the public
or the environment through the exposure of people or structures to potential substantial adverse
effects. In addition, the General Plan Update includes goals, policies, and actions that would
further reduce risks from geologic hazards.
Would the project be located on a geologic unit or soil that is unstable our would become
unstable, or potentially result in a potentially significant risk from on- or off-site landslide, lateral
spreading, subsidence, liquefaction, or collapse? Would the project be located in an area of
expansive soils?
The General Plan Update does not consider or analyze specific development projects; therefore,
the actual potential for future construction sites or developments associated with the General
Plan Update are unknown. However, given the relatively stable geology and soils within the City,
it is unlikely that there would be a potential risk that represents a significant change or increase
from the conditions that are currently present.
According to the General Plan FEIR, compliance with federal, state, and local regulations would
minimize the risks associated with the potential risk from landslides, subsidence, liquification, or
collapse relative to existing conditions. According to the City of Fontana 2017 LHMP, there have
City of Fontana | Addendum to the General Plan FEIR for the
Community Mobility and Circulation Element Update
Addendum Finding 43
been no reported historical occurrences of landslides in the City of Fontana. The only areas
susceptible to landslips are the southern Jurupa hillsides and the northern part of the city close to
the San Bernardino National Forest, but there is a low probability of this hazard affecting these
areas in the future. Therefore, the General Plan FEIR concluded that future development under
the General Plan Update would result in a less than significant impact relative to these potential
risks.
Adherence to building codes and development that includes site specific geotechnical studies
that would be prepared for each specific future project as mandated by the CBC would identify
and minimize risks from areas of unstable soils by ensuring the incorporation of recommendations
from the site-specific geotechnical investigations into design of plan for those future projects.
Overall, the Planning Area would not be located on a geologic unit or soil that is unstable. In
addition, the General Plan Update includes goals, policies, and actions would further reduce risks
from geologic hazards. Accordingly, the General Plan FEIR concluded impacts are less than
significant.
Would the project 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?
The General Plan Update does not consider or analyze specific development projects; therefore,
the actual potential for future construction sites or developments associated with the Update are
unknown. According to the General Plan FEIR, the City of Fontana has limited septic systems and
given the relatively stable geology and soils within the City, it is unlikely that there would be a
potential risk that represents a significant change or increase from the conditions that are currently
present. Overall, the City of Fontana is served by a sewer system and the use of septic systems or
other alternative wastewater disposal systems would be managed on a case-by-case basis.

The Project does not propose site-specific development; rather, it involves amendments to the
General Plan Community Mobility and Circulation Element to comply with AB 98 requirements
related to the City’s truck-route network. Specifically, the City’s existing Truck Route Map (Exhibit
9.7, Truck Routes) would be updated to shift truck traffic away from residential uses and sensitive
receptors, while also clarifying what facilities are officially part of the City-controlled local truck
route network. The Project also proposes minor text changes to existing policies and actions in the
City’s Community Mobility and Circulation Element, as well as the addition of new policies and
actions, to further address AB 98 requirements to provide specific truck route requirements and
avoid residential areas and sensitive receptors, as well as direct the City towards meeting other
AB 98 requirements.
The proposed Project would not result in any modifications to existing land use designations or
modify any existing roadways or roadway classifications or allow for any specific circulation system
projects or improvements. The Project would not modify any General Plan policies or programs
specific to geology and soils.
The Project does not propose any development and proposed changes to the City’s truck -route
network would occur within the rights-of-way of existing local roadways. Further, the Project
involves a citywide redistribution of truck trips on City roadways; the Project would not create new
truck trips within the City or region. As such, the Project would not directly or indirectly cause
potential substantial adverse effects, including the risk of loss, injury, or death involving rupture of
a known earthquake fault, strong seismic ground shaking, seismic-related ground failure, including
liquefaction, or landslides. In addition, the Project would not result in substantial soil erosion or the
loss of topsoil.
As discussed, the Project does not propose any development and proposed changes to the City’s
truck-route network would occur within the rights-of-way of existing local roadways. While
geological conditions underneath these roadways may vary, roadways are required to be
designed and constructed in accordance with applicable roadway standards, which would
address potential impacts related to geological hazards. The Project involves a citywide
redistribution of truck trips on City roadways; the Project would not create new truck trips within
the City or region. As such, the Project would not 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

The Project does not involve development and does not propose any changes related to septic

The General Plan includes goals, policies, and actions to reduce potential geologic and soil
hazards. The proposed amendments to the General Plan Community Mobility and Circulation
Element would not conflict with implementation of these General Plan goals, policies, or actions
or the General Plan FEIR mitigation measures.
Conclusion
The Project would not result in new or greater geology and soils impacts beyond those identified
in the General Plan FEIR.

General Plan FEIR Conclusions
Would the project generate greenhouse gas emissions, either directly or indirectly, that may have
a significant impact on the environment?
As discussed in the General Plan FEIR, implementation of the General Plan Update would
generate short-term construction and long-term operational GHG emissions associated with future
development projects.
Short-Term Emissions. Typically, construction-related GHG emissions contribute unsubstantially (less
than one percent) to a project’s annual greenhouse gas emissions inventory and mitigation for
construction-related emissions is not effective in reducing a project’s overall contribution to
climate change, given how small of a piece of the total emissions construction emissions are.
Short-term climate change impacts due to future construction-related activities would be subject
to State requirements for GHG emissions and would be assessed on project-by-project basis.
Furthermore, the General Plan Update policies related to Community Mobility and Circulation and
Sustainability and Resilience indicate the City of Fontana’s commitment to reduce greenhouse
gas emissions are consistent with State goals. Implementation of AB 32 and SB 375 through ARB’s
Scoping Plan and SCAG’s 2016 RTP/SCS are also designed to achieve the required reduction in
greenhouse gas emissions.
Long-Term Emissions. Future development projects will result in continuous GHG emissions from
mobile, area, and operational sources. With implementation of the General Plan Update, the City
of Fontana planning area is estimated to grow to a total population of 315,852, which is an
approximately 12% increase compared to the population forecast assumed in the RTP/SCS and
has the potential to be inconsistent with the 2016 AQMP. However, the land use modifications and
policies proposed as part of the General Plan Update would result in an approximately 19%
City of Fontana | Addendum to the General Plan FEIR for the
Community Mobility and Circulation Element Update
Addendum Finding 47
reduction in per capita vehicle miles traveled compared to 2040 buildout of the 2003 General
Plan. Despite the projected population growth (including employment) associated with the
General Plan Update, daily total vehicle miles traveled within the planning area would be
reduced from by approximately 9%.
According to the CARB’s 2017 Climate Change Scoping Plan, the transportation sector remains
the largest source of GHG emissions in the State, accounting for 37% of the inventory. To further
evaluate potential long-term increases in GHG emissions because of the land use modifications
associated with the General Plan Update, land use-specific emissions factors were estimated
using CalEEMod and applied to the land use acreages in the 2003 General Plan and General Plan
Update. As shown in Table 5.6-6 of the General Plan FEIR, implementation of the General Plan
Update including the 9% reduction in vehicle miles traveled achieved by the goals and policies
of the General Plan Update, would result in a substantial net reduction in greenhouse gas
emissions compared to the 2003 General Plan. The General Plan FEIR concluded potential impacts
would therefore be less than significant.
In addition, the General Plan FEIR determined that policies in the General Plan Update support
actions that reduce GHG emissions and help to quantify emissions reductions (refer to Table 5.6-6
in the General Plan FEIR). The Community Mobility and Circulation Element of the General Plan
Update supports options for transit and active transportation (pedestrian and bicycle mobility) for
Fontana. These concepts are consistent with the SCAG 2016 RTP/SCS concepts of Neighborhood
Mobility Areas and Livable Corridors and are applied in the General Plan Update as “Connected
Neighborhoods.” The Sustainability and Resilience Element of the General Plan Update supports
the concept of environmental sustainability. Environmental sustainability is defined as the ability
of the environment to continue to properly function indefinitely. The element establishes goals and
policies in the categories of energy, waste reduction, urban design, urban nature, transportation,
environmental health, water and energy efficient city buildings and facilities.
Would the project conflict with an applicable plan, policy or regulation adopted for the purpose
of reducing the emissions of greenhouse gases?
California Air Resources Board Scoping Plan (AB 32)
CARB’s 2017 Scoping Plan identifies strategies to reduce California’s greenhouse gas emissions in
support of AB 32. The General Plan Update will not conflict with the implementation of regional
transportation-related GHG targets outlined in SCAG’s RTP/SCS because the land use
modifications and reduction in vehicle miles traveled result in lower emissions than those
forecasted in the RTP/SCS, nor would it conflict with any of the other provisions of the Scoping Plan
or applicable regulation related to GHG reductions. Fontana’s General Plan Update supports the
Plan through energy efficiency, green building, recycling/waste, and water conservation through
proposed goals, objectives, and policies. The General Plan FEIR concluded potential impacts
would be less than significant.

Analysis of Project
a. Would the project generate greenhouse gas emissions, either directly or indirectly, that
may have a significant impact on the environment?
Emissions of GHGs contributing to global climate change are attributable in large part to human
activities associated with the industrial/manufacturing, utility, transportation, residential, and
agricultural sectors. Therefore, the cumulative global emissions of GHGs contributing to global
climate change can be attributed to every nation, region, and city, and virtually every individual
on Earth. A project’s GHG emissions are at a micro-scale relative to global emissions but could
result in a cumulatively considerable incremental contribution to a significant cumulative macro-
scale impact. Estimated GHG emissions attributable to the Project would be primarily associated
with increases of CO2 and other GHG pollutants, such as methane (CH4) and nitrous oxide (N2O),
from the nominal increase in VMT related to truck rerouting. According to the Traffic Memorandum
prepared for the proposed Project (Kittelson & Associates, 2025), the Project would increase truck
VMT by approximately 797 VMT. Estimated GHG emissions related to the increase in 797 VMT due
to the proposed Project are summarized in Table 3, Project Operational GHG Emissions (Metric
Tons/Year). Truck emissions associated with VMT were calculated based on emission rates
calculated with the California Air Resources Board’s EMFAC emission factor model. EMFAC2025
was used to calculate emission rates based on heavy-duty trucks within San Bernardino for the
year 2040. Calculation sheets for these emissions are provided in Appendix A. As shown Table 3,
the annual mitigated GHG emissions associated with the proposed Project would be
approximately 148 MT CO2e. This is below the SCAQMD’s interim draft threshold of significance of
10,000 MT CO2e for GHG emissions for industrial projects. Since truck related travel within the City
supports industrial uses, the use of the industrial land use based threshold is appropriate. Because
Project related GHG emissions are below the SCAQMD’s significance threshold, the Project would
result in less than significant GHG impacts related to the generation of GHG emissions.

The Project does not propose site-specific development; rather, it involves amendments to the
General Plan Community Mobility and Circulation Element to comply with AB 98 requirements
related to the City’s truck-route network. Specifically, the City’s existing Truck Route Map (Exhibit

route network. The Project also proposes minor text changes to existing policies and actions in the
City’s Community Mobility and Circulation Element, as well as the addition of new policies and
actions, to further address AB 98 requirements to provide specific truck route requirements and
avoid residential areas and sensitive receptors, as well as direct the City towards meeting other
AB 98 requirements.
The proposed Project would not result in any modifications to existing land use designations or
modify any existing roadways or roadway classifications or allow for any specific circulation system
projects or improvements. The Project would maintain the broader multi-modal framework
established in the Fontana Forward General Plan Update 2015–2035, which would contribute to
reduced automobile trips and VMT, supporting reductions in regional GHG emissions.
The Project does not propose modifications to existing land use designations, does not propose
site-specific development, and does not authorize or facilitate future development projects.
Further, the Project would not create new truck trips within the City or region; rather, the updates
to the Truck Route Map would identify specific routes existing trucks within the City would be
required to utilize when traveling within the City. Increases in GHG emissions due to the
redistribution of truck traffic to sensitive land uses were found to be a small fraction of the
SCAQMD’s draft interim threshold for industrial uses and would result in less than significant impacts
related to GHG emissions. As such, the Project would not increase GHG emissions or conflict with
applicable GHG plans, policies, or regulations.
Conclusion
The Project would not result in new or greater greenhouse gas emissions impacts beyond those
identified in the General Plan FEIR.
Applicable General Plan FEIR Mitigation Measures: No mitigation measures are required.

Would the project create a significant hazard to the public or the environment through the routine

Would the project create a significant hazard to the public or the environment through reasonably

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?
As discussed in the General Plan FEIR, implementation of the General Plan Update will not directly
result in any specific development project; individual projects would undergo environmental
review as they are proposed. As such, the General Plan FEIR discussion focuses on potential
hazardous materials impacts associated with new land use policies and actions contained in the
General Plan Update to guide future development in the City. Notwithstanding, it should be noted
that no new development under the General Plan Update is proposed in locations that are
currently identified in Government Code section 65962.5 (referred to as the Cortese List).
The General Plan Update would introduce new land uses to the City that may, in turn, result in new
uses of hazardous materials and the potential generation of hazardous waste greater than current
conditions. With new industrial and mixed-use development proposed under the General Plan
Update, there is an increased potential for spills and accidents involving hazardous materials to
occur where such materials are newly used, handled, transported, and disposed of, thereby
causing possible injury or harm to humans and the environment. However, the General Plan FEIR
concluded that compliance with federal, state, county, and local regulations relating to the use,
storage, handling, transport, and disposal of hazardous materials would reduce the potential risk
of hazardous materials exposure to a less than significant level. Furthermore, household hazardous
materials or wastes, such as paint, chemicals, oil, anti-freeze, pesticides, cleaners, etc., are
required to be disposed of at the City’s Household Hazardous Waste facility, in accordance with
State and local regulations.
Implementation of the General Plan Update would not result in impacts associated with known
and/or suspected hazardous materials. However, there is a potential that previously unknown
hazardous material contamination from historical use of a property may be encountered during
future development activities. Should such contamination be discovered, existing federal, state,
and local regulations would require delineation of properties containing hazardous substances,
and remediation of those properties to a level approved by the designated enforcement agency.
As such, the General Plan FEIR concluded that with compliance with existing regulations
pertaining to hazardous materials contamination, impacts associated with hazardous materials
would be less than significant. In addition, the General Plan Update includes goals, policies, and
City of Fontana | Addendum to the General Plan FEIR for the
Community Mobility and Circulation Element Update
Addendum Finding 52
actions that could further reduce risk of improper use, storage, and/or transport of hazardous
materials.
Would the project emit hazardous emissions or handle hazardous or acutely hazardous materials,
substances, or waste within one-quarter mile of an existing or proposed school?
The General Plan Update does not approve site-specific development. Given the distribution of
schools citywide, some future projects could occur within one-quarter mile of existing or proposed
schools; however, all businesses that handle or transport hazardous materials on site would be
required to comply with federal, state, and local regulations for hazardous wastes. This includes
submittal of a Hazardous Materials Business Plan under Health and Safety Code Chapter 6.95,
consideration of school proximity under CEQA Guidelines Section 15186, and siting provisions for
new schools per Education Code Section 17210. Given the above, compliance with federal, state,
and local regulations would minimize the risks associated with the exposure of school populations
to hazardous materials. Therefore, the General Plan FEIR concluded that future development
under the General Plan Update would result in a less than significant impact relative to the
emissions or handling of hazardous materials within one-quarter mile of school facilities.
Would the project result in a safety hazard for people residing or working in the project area 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 for people residing or working in the project area for a
project within the vicinity of a private airstrip?
There are no private airstrips located within or in the vicinity of the City. Therefore, the General
Plan FEIR concluded that no impact would occur as a result of General Plan Update
implementation with respect to people residing or working in the vicinity of a private airstrip. For
public airports, the General Plan is required to be consistent with applicable airport land use
compatibility plans. Proposed development under the General Plan Update within the noise
contours of the Airport Compatibility Plan would be substantially similar to existing development
(i.e., industrial uses). Further, the Airport Compatibility Plan concluded that land uses that fall within
the noise impact zone are industrial land uses. Projected 2020 conditions in the Noise Impact Map
for the Ontario Airport in the Airport Compatibility Plan show 65-decibel contour extending to the
intersection of E. Santa Ana Street and S. Wineville Road, located in Ontario near the western
edge of Fontana. However, Title 21 (State Noise Standards) establishes that a CNEL of 65 decibels
is the standard for the acceptable level of aircraft noise for persons living in the vicinity of airports.
With adherence to existing state and local regulations, the General Plan FEIR concluded that
impacts related to people residing or working within an airport land use plan would be less than
significant. In addition, the General Plan Update’s Noise and Safety Element contains several
goals, policies, and actions to minimize noise impacts to people and the environment in the
vicinity of sources of noise.
City of Fontana | Addendum to the General Plan FEIR for the
Community Mobility and Circulation Element Update
Addendum Finding 53
Would the project impair implementation of or physically interfere with an adopted emergency
response plan or emergency evacuation plan?
Implementation of the General Plan Update could generate an increase in the residential and
employee population in the City as a result of the construction of new residential housing and
commercial/retail growth. This new development could, in turn, result in an increase in traffic.
These new potential sources of congestion on local roads and freeways could increase response
times for medical or other emergencies and could delay evacuation of the population in an
emergency.
According to the City’s LHMP, numerous alternative routes, secondary points of access, cul-de-
sac turnarounds, and other features that improve traffic circulation are planned into new
development and redevelopment during the City's internal review process, which includes the
Fire Department. These ongoing mitigations are in place so that emergency vehicles may respond
quickly. Additionally, installation of security gate override systems and traffic signal pre-emption
devices at critical signalized intersections are ongoing mitigations for systems that could otherwise
obstruct or impair emergency access.
As discussed in the General Plan FEIR, the General Plan Update does not propose changes to
circulation in the City or to physical orientation of the Project area that could interfere with the
City’s emergency response or evacuation procedures. In addition, the General Plan Update does
not propose to change or eliminate existing emergency response facilities such as fire stations.
Furthermore, goals, policies, and actions in the Community Mobility and Circulation Element do
not involve modifications to roadways in any manner that would impede response to an
emergency. The General Plan Update goals, policies, and actions are consistent with the LHMP.
Given the above, compliance with the mitigation program contained in the City’s LHMP, along
with implementation of the policies and actions in the Noise and Safety Element and the
Community Mobility and Circulation Element of the General Plan Update, the General Plan FEIR
concluded that the General Plan Update would result in a less than significant impact to the City’s
emergency response plan or emergency evacuation plan.
Would the project expose people or structures to a significant risk of loss, injury or death involving
wildland fires, including where wildlands are adjacent to urbanized areas or where residences are
intermixed with wildlands?
The General Plan Planning Area is urbanized and surrounded by other urbanized communities;
however, growth has occurred adjacent to or in the vicinity of areas prone to wildfire within the
community. Historically, most of the wildfires in Fontana have occurred in northwest Fontana, with
occasional fires in the Jurupa Hills.
Under the General Plan Update, the master planned communities developed through the specific
plan process since the 1980s that are located in the northern and southern portions of the City are
not anticipated to experience land use changes over the next 20 years. These are areas that are
geographically closer to the foothills to the north and south that are more prone to wildland fires.

However, there are areas within the northern portion of the City that may be developed for
residential and mixed uses, including: approximately 269 acres of currently undeveloped land
along the southern edge of I-15, between Duncan Canyon and the northern edge of the City;
and approximately 101 acres in the Ventana Specific Plan near the Duncan Canyon interchange.
The State of California Department of Forestry and Fire Protection (CalFIRE) has created, and
continues to revise, a map of all Fire Hazard Severity Zones (FHSZ) within the state, including those
in the City. The “Very High FHSZ” can be used to enforce enhanced regulations from the State Fire
Marshal published within the California Building Code that relates to ignition and ember resistive
building construction within the City. In addition, a Fire Hazard Overlay District (included in the
City’s Zoning and Development Code) in the northern and southern portions of the City are
subject to regulations to mitigate risk from wildfire. The overlay district provides requirements for
fire resistive construction, fuel modification areas, development property line setbacks, and
vegetation clearances from roadways and buildings.
The General Plan Update includes goals, policies, and actions to reduce risk of urban fires in the
project area. The General Plan FEIR concluded that with compliance with existing state and local
regulations, the City’s Zoning and Development Code, and mitigation in the LHMP – supported by
implementation of the General Plan Update policies and actions relative to development in fire-
prone areas – impacts to the public and environment related to risk of hazards due to wildland
fire would be less than significant.

rather, it involves amendments to the General Plan Community Mobility and Circulation Element
to comply with AB 98 requirements related to the City’s truck-route network. Specifically, the City’s
existing Truck Route Map (Exhibit 9.7, Truck Routes) would be updated to shift truck traffic away
from residential uses and sensitive receptors, while also clarifying what facilities are officially part
of the City-controlled local truck route network. The Project also proposes minor text changes to
existing policies and actions in the City’s Community Mobility and Circulation Element, as well as
the addition of new policies and actions, to further address AB 98 requirements to provide specific
truck route requirements and avoid residential areas and sensitive receptors, as well as direct the
City towards meeting other AB 98 requirements.
The proposed Project would not result in any modifications to existing land use designations or
modify any existing roadways or roadway classifications or allow for any specific circulation system
projects or improvements. Sites included on a list of hazardous materials sites compiled pursuant
to Government Code Section 65962.5 are associated with specific development properties; there
are no public rights-of-way identified on the Cortese list. Further, the Project would not create new
truck trips within the City or region; rather, the updates to the Truck Route Map would identify
specific routes existing trucks within the City would be required to utilize when traveling within the
City. As such, the Project would not increase the transport of potentially hazardous materials within
the City or region or introduce new hazards that may cause accidental spills or hazardous
materials release. Similar to of the General Plan FEIR, compliance with federal, state, county, and
local regulations relating to the use, storage, handling, transport, and disposal of hazardous
materials would reduce the potential risk of hazardous materials exposure to a less than significant
level.
The Fontana city limits are located approximately three miles east of the nearest point of the
Ontario International Airport runway, and the southern half of the City is located within the

boundaries of the airport influence area of the Ontario International Airport Land Use
Compatibility Plan. As discussed in the General Plan FEIR, the airport influence area includes areas
in which current or future airport-related safety, noise, airspace protection, or overflight factors
may significantly affect land uses or necessitate restrictions on those uses. As shown in the Safety
Zones map of the Ontario Airport in the Airport Compatibility Plan, the City is not located within
any safety zones associated with the Ontario Airport. The Noise Impact Zones map for the Ontario
Airport in the Airport Compatibility Plan show the 65-70 decibel and 60-65 decibel CNEL contours
extending into the western edge of Fontana, in an area located north of Jurupa Avenue and
south of Slover Avenue. The Project does not propose to designate any new roadway segments
within the noise contours identified in the Ontario Airport in the Airport Compatibility Plan beyond
the roadway segments that are already designated in the existing Truck Route Map. As such, the
Project would not result in new or greater safety or noise impacts related to airports.
Similar to existing conditions, emergency vehicles would not be subject to the Truck Route Map.
Neither the existing General Plan Community Mobility and Circulation Element nor the City’s Local
Hazard Mitigation Plan identify evacuation routes. The LHMP states that interstates serve as major
emergency response and evacuation routes in the City. The proposed amendments to the
General Plan Community Mobility and Circulation Element would not designate new or alter
existing emergency vehicle or evacuation routes. Emergency evacuation routes would continue
to be identified at the time of an emergency in coordination with emergency responders with
major roadways and interstates serving as primary evacuation routes. The proposed amendments
to the General Plan Community Mobility and Circulation Element would further support and
facilitate goods movement and are not anticipated to increase congestion on designated truck
routes that could interfere with the City’s emergency response or evacuation procedures. Similar
to existing conditions, trucks would be required to yield the right-of-way to emergency vehicles in
compliance with the California Vehicle Code. As such, the Project would not conflict with
emergency response and evacuation.
According to CalFIRE’s FHSZ maps, there are Very High FHSZ in Local Responsibility Area within the
northern and southern portions of Fontana.1 The City’s existing Truck Route Map designates a
portion of Jurupa Avenue which is within a Very High FHSZ as a truck route. Similar to existing
conditions, the Project proposes to designate this portion of Jurupa Avenue which is within a Very
High FHSZ as a truck route. The Project does not propose to designate any new truck routes in Very
High FHSZs or State Responsibility Areas beyond the roadway segments that are already
designated in the existing Truck Route Map. As such, the Project would not result in new or greater
impacts related to wildfire hazards.
The General Plan includes goals, policies, and actions to protect and prepare the community
from hazards and hazardous conditions, including from human activity and wildland fires. The
proposed amendments to the General Plan Community Mobility and Circulation Element would

actions and the addition of new policies and actions to meet the City’s goods movement needs
while avoiding residential areas and sensitive receptors, including schools. As such, the Project
would not increase hazards and hazardous conditions or interfere with an adopted emergency
response plan or emergency evacuation plan.
Conclusion
The Project would not result in new or greater hazards and hazardous materials impacts beyond
those identified in the General Plan FEIR.
Applicable General Plan FEIR Mitigation Measures: No mitigation measures are required.

General Plan FEIR Conclusions
Would the project substantially increase the rate or amount of surface runoff in a manner that
would result in flooding on- or off-site, or create or contribute runoff water that would exceed the
capacity of existing or planned stormwater drainage systems to provide the designed level of
flood control?
As discussed in the General Plan FEIR, implementation of the General Plan Update could result in
additional households and employees within the General Plan Planning Area that will entail
construction of projects with impervious surfaces. The focus for growth in the General Plan Update
is in the Downtown Core of the City and “Livable Corridors” which is currently developed and
contains stormwater drainage facilities. The construction of structures and facilities with impervious
surfaces in areas where there are currently no impervious surfaces, potentially increasing the rate
of stormwater runoff compared to existing conditions. The City has adopted existing regulations
and policies that minimize on- and off-site flooding which can alter drainage patterns or stream
course and cause erosion and sedimentation impacts. The floodway and floodplain districts
regulations contained in the Municipal Code are specifically designed to prevent and regulate
development in flood-prone areas.
MS4 permit requirements include the reduction of pollutant discharges to the maximum extent
practicable (MEP) and protection of water quality. Requirements also include identification of
major outfalls and pollutant loads and control of discharges from new development and
redevelopment. Future projects undertaken over the planning horizon of the General Plan Update
may cause changes in drainage patterns, increased imperviousness, and other effects that could
potentially alter local hydrology that could cause or contribute to local flooding and exceedance
of local drainage system capacity. However, the City of Fontana is subject to the NPDES permitting
process under its MS4 codified as Title 14 (Storm Drains and Flood Management) of the Municipal
Code. Implementation of the requirements of the MS4 permit and other regulations would ensure
that the volume and rate of stormwater runoff from future development would not exceed local
drainage volume and flow requirements and would prevent downstream flooding. The General
Plan FEIR concluded that this would reduce potential stormwater runoff and drainage impacts to
less-than-significant levels. Further, the General Plan Update includes Goals, Policies, and Actions
that would further reduce impacts to hydrologic resources.
Would the project substantially alter the existing drainage pattern of the site or area in a manner
that would generate substantial additional sources of polluted runoff, substantially degrade water
quality, or violate any water quality standards or WDR?
The General Plan Update does not consider or analyze specific development projects; therefore,
the actual potential for future construction sites or developments associated with the General
Plan Update Goals, Policies, and Actions are unknown. Future projects must comply with the City’s
MS4 permit and Title 14 of the Municipal Code, implementing NPDES requirements and best
management practices to control pollutants in urban runoff. Implementation of the requirements
of the MS4 permit and other regulations would ensure that the volume and rate of stormwater

Community Mobility and Circulation Element Update
Addendum Finding 60
runoff from future development would not exceed local drainage volume and flow requirements
and would prevent downstream flooding. The General Plan FEIR concluded that this would reduce
potential stormwater runoff and drainage impacts to less-than-significant levels. Further, the
General Plan Update includes Goals, Policies, and Actions that would further reduce impacts to
hydrologic resources.
Would the project result in a net deficit in aquifer volume or a lowering of the local groundwater
table level at the projects site such that existing uses in the groundwater area of influence that rely
on groundwater wells could not be reasonably supported?
Future development within the Planning Area would require additional water services that would
come from local groundwater sources. Future development may also impact groundwater
recharge by increasing impervious surfaces that could hinder percolation of drainage into
subsurface aquifers. Future development could also impact groundwater recharge if existing
spreading grounds are altered (e.g., developed upon) without construction of replacement
facilities. Additionally, drainage may be directed away from its natural source where it may be
deposited in other water bodies.
The General Plan Update does not consider or analyze specific development projects; therefore,
the actual potential for future construction sites or developments associated with the General
Plan Update Goals, Policies, and Actions are unknown. Groundwater production and recharge in
the Santa Ana River Watershed, including the Santa Ana Groundwater Basin, are managed under
the 1969 Stipulated Agreement and overseen by the Santa Ana River (SAR) Watermaster to
maintain safe basin operating levels. Future projects must comply with applicable conservation,
recycling, and recharge provisions, and the General Plan supports water‐efficient landscaping,
reuse, and recharge practices that reduce demand and aid replenishment. As a result, the
General Plan FEIR concluded that the potential for impacts to groundwater levels within the region
is less than significant. Further, the General Plan Update includes Goals, Policies, and Actions that
would further reduce impacts to hydrologic resources.
Would the project expose people or structures to a significant risk of loss, injury or death involving
as a result of the failure of a levee or dam?
The General Plan Update does not consider or analyze specific development projects; therefore,
the actual potential for future construction sites or developments associated with the General
Plan Update Goals, Policies, and Actions are unknown. However, some future development could
result in the construction of certain structures and infrastructure in the SAR floodplain that would
be exposed to flood conditions from the 100-year flood event as mapped by the FEMA in the
Flood Insurance Rate Map (FIRM) for the area. Furthermore, the City of Fontana is not located in
a mapped dam inundation area.
There are areas shown on the FIRM as having minimal risk from the failure or overtopping of a levee
or flood control channel. These are on the Hawker Crawford Channel, the Etiwanda/San Sevaine
Channel, San Sevaine Channel, and West Fontana Channel. These are either delineated as

Shaded Zone X (i.e., areas protected from flooding by a levee), Zone X (i.e., 500-year floodplain),
Zone A (i.e., no base flood elevations determined), or Zone AO (i.e., depth 1 foot) on the FIRM. As
a National Flood Insurance Program (NFIP) participant, the City administers floodplain
development permits and floodplain management ordinances that regulate construction in
Special Flood Hazard Areas to reduce flood risk. Therefore, the General Plan FEIR concluded
impacts from flooding due to a 100- year event or from the failure of a levee or dam would be
less than significant. Further, the General Plan Update includes Goals, Policies, and Actions that
would further reduce impacts to hydrologic resources.
Analysis of Project
a. Would the project violate any water quality standards or waste discharge requirements or
otherwise substantially degrade surface or groundwater quality?
b. Would the project substantially decrease groundwater supplies or interfere substantially
with groundwater recharge such that the project may impede sustainable groundwater
management of the basin?
c. Would the project substantially alter the existing drainage pattern of the site or 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:

d. Would the project, in flood hazard, tsunami, or seiche zones, risk release of pollutants due
to project inundation?
e. Would the project conflict with or obstruct implementation of a water quality control plan
or sustainable groundwater management plan?
The Project does not propose site-specific development; rather, it involves amendments to the
General Plan Community Mobility and Circulation Element to comply with AB 98 requirements
related to the City’s truck-route network. Specifically, the City’s existing Truck Route Map (Exhibit
9.7, Truck Routes) would be updated to shift truck traffic away from residential uses and sensitive
receptors, while also clarifying what facilities are officially part of the City-controlled local truck
route network. The Project also proposes minor text changes to existing policies and actions in the

avoid residential areas and sensitive receptors, as well as direct the City towards meeting other
AB 98 requirements.
The proposed Project would not result in any modifications to existing land use designations or
modify any existing roadways or roadway classifications or allow for any specific circulation system

specific to hydrology and water quality. The General Plan includes goals, policies, and actions to
protect water quality and groundwater recharge, reduce potential impacts to drainage patterns,
and reduce impacts due to inundation. The proposed amendments to the General Plan
Community Mobility and Circulation Element would not conflict with implementation of these
General Plan goals, policies, or actions or the General Plan FEIR mitigation measures.
Conclusion
The Project would not result in new or greater hydrology and water quality impacts beyond those
identified in the General Plan FEIR.

General Plan FEIR Conclusions
Would the project physically divide an established community?
The General Plan Update represents a policy-level project designed to direct long-term growth
within the planning area. The General Plan Update Land Use Map retains the City’s commercial,
industrial, and residential character. However, the Walkable Mixed-Use land uses are introduced
in the City’s downtown core. Neither would they indirectly lead to the division of an established
community, as the changes would not trigger the development of major new infrastructure (such
as major roads or freeways, power easements, or water conveyance facilities), which could
physically divide existing developed areas of the City. The new mixed-use land use categories
would not impact established communities since the land use categories encourage infill
development on vacant parcels and enhance community character. In addition, the mixed-use
land uses allow for safe and convenient walking to nearby shopping and maintenance of
established neighborhoods through the following goals and policies in the General Plan Update.
Therefore, the General Plan FEIR concluded potential impacts would be less than significant.
Would the project 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?
The General Plan FEIR concluded that none of the changes in the General Plan Update would
affect plans, policies, or regulations of other agencies that have jurisdiction within the planning
area.
With regard to state policy frameworks, the goals, policies, and actions of the General Plan
Update are consistent with State of California climate-change policy framework. The vision of the
City of Fontana | Addendum to the General Plan FEIR for the
Community Mobility and Circulation Element Update
Addendum Finding 64
California Climate Strategy is to reduce greenhouse gas emissions to 40% below 1990 levels by
2030. This is consistent with the City of Fontana’s General Plan Update Goals and Policies. With
regards to the San Bernardino County General Plan, the goals, policies, and actions of the
Fontana General Plan Update are consistent with the adopted San Bernardino Countywide Vision.
The San Bernardino Countywide Vision illustrates the “support for creation of environments and
protection of rural lifestyles to design senses of place that reflect local community values and
history.” Similarly, the City of Fontana General Plan Update reiterates these visionary elements by
encouraging a complete price range of housing from affordable to luxury and the improvement
of livability and energy efficiency through smart planning, design, and technology. Goals and
Policies of the General Plan Update are consistent with the San Bernardino County’s General Plan.
The Countywide Plan is intended to “go well beyond” a traditional general plan to become a
comprehensive Countywide Plan that complements and informs the Countywide Vision by taking
into account all services, not just land-use planning, provided by the County Government.
San Bernardino County has jurisdiction over land uses within the SOI and there is a proposed
application for a project within the SOI. The proposed project is subject to a variety of Federal,
State, and locally adopted plans designed to mitigate environmental impacts or to preserve
important resources. Plans and policies related to specific resource issues are addressed in those
specific sections of the General Plan FEIR.
No conflicts between the specific resources and a policy or regulation of another agency would
occur as a result of the proposed project. Therefore, the General Plan FEIR concluded impacts
would be less than significant.

established community.
The Project would not modify any General Plan policies or programs specific to land use. The
General Plan includes goals, policies, and actions to ensure development occurs consistent with
the General Plan and other adopted plans designed to mitigate environmental impacts or to
preserve important resources. The proposed modifications to goals and policies within the
Community Mobility and Circulation Element include text revisions to ensure compliance with AB
98, such as maintaining a designated truck route network that avoids sensitive uses while
continuing to accommodate efficient movement of trucks; enforcing designated truck routes;
developing and maintaining signage and an online map of citywide truck routes; and updating
the truck route map as needed. A new policy has also been proposed to provide for coordination
with regional agencies and adjacent jurisdictions on regional goods movement planning and
cross-jurisdictional consistency. The proposed modifications and introduction of a new policy
would not conflict with any land use plan, policy, or regulation adopted for the purpose of
avoiding or mitigating an environmental effect. Impacts would be less than significant.
Conclusion
The Project would not result in new or greater land use and planning impacts beyond those
identified in the General Plan FEIR.

would continue to be protected over the long term. Overall, the General Plan FEIR concluded
that the General Plan Update would not contribute to a loss of mineral resources.

General Plan FEIR Conclusions
Would the Project expose persons to or generation of noise levels in excess of standards
established in the local general plan or noise ordinance, or applicable standards of other
agencies?
Future development could generate construction and operational noise. With respect to
construction impacts, construction or repairing of buildings or structures under the General Plan
Update would be restricted by City ordinance to 7:00 am to 6:00 pm on weekdays and between
8:00 am and 5:00 pm on Saturdays, except in case of urgent necessity in the interest of public
health and safety, and then only with a permit from the building inspector (Municipal Code of
Ordinances, Chapter 18, City of Fontana).
With respect to operations impacts, while future development under the General Plan Update
could result in the exposure to persons to or generate noise levels in excess of City standards,
potential increases in noise levels would be assessed in conjunction with the city’s review of site-
specific noise impact analysis. In accordance with the City of Fontana Municipal Code of
Ordinances (Chapter 18), standards for exterior and interior noise levels have also been
City of Fontana | Addendum to the General Plan FEIR for the
Community Mobility and Circulation Element Update
Addendum Finding 69
established to protect residents from noise levels in excess of acceptable levels. In the event
significant impacts are anticipated, appropriate mitigation would be developed at that time. In
addition, the General Plan Update includes Goals, Policies, and Actions that pertain to protecting
new development from noise impacts through compatible use with surrounding areas, road
maintenance standards, and setbacks.
Would the project result in generation of excessive groundborne vibration or groundborne noise
levels?
Construction and heavy vehicle activity could generate groundborne vibration and noise,
including possible pile driving near sensitive uses. However, construction hours are limited by the
Municipal Code, and the City’s performance standards prohibit perceptible vibration at
residential property lines. According to the General Plan FEIR, unless the vibration results in physical
damage to local structures, it does not constitute a significant impact.
Future construction activities would be assessed in conjunction with the City’s routine review of
site-specific geotechnical studies and the recommended grading and foundation design
measures. For projects subject to review under CEQA, measures to mitigate potentially significant
vibration impacts must be considered in the project planning process, prior to project approvals.
The General Plan FEIR concluded that by complying with the City Noise Ordinance, California
Building Code standards, and applicable regulations, potential vibration impacts from future
development would be less than significant.
Would the Project result in a substantial permanent increase in ambient noise levels in the project
vicinity above levels existing without the Project?
According to the General Plan FEIR, increases in traffic could result in permanent increases in
ambient noise levels, e.g., where a roadway segment is proposed to be expanded with additional
travel lanes over the long-term to achieve level of service standards. Roadway noise could also
increase on an existing roadway that will carry increasing traffic volumes. In either scenario,
roadway noise levels could increase to beyond the levels considered acceptable for the
adjacent land uses. The City’ s noise ordinance contains standards for mobile noise sources and
outdoor and indoor noise limits for residential uses, places of worship, educational facilities,
hospitals, hotels/motels, and commercial and other land uses. The noise standard for exterior living
areas is 65 dBA CNEL. The indoor noise standard is 45 dBA CNEL, which is consistent with the State
of California Interior and Exterior Noise Standards. As well, the City’s ordinance specific to industrial
zoning districts (Sec. 30-239 - Land use compatibility) specifies development policies to minimize
noise levels, such as consideration of physical barriers, building orientation, and infill development.
The General Plan FEIR concluded that continued enforcement of these policies and standards
would reduce potential permanent ambient noise impacts. Each future project would be
evaluated on a case-by-case basis pursuant to CEQA, and appropriate noise thresholds
established. In the event significant impacts are anticipated, appropriate mitigation would be
developed at that time. In addition, the General Plan Update’s Noise and Safety Element contains
City of Fontana | Addendum to the General Plan FEIR for the
Community Mobility and Circulation Element Update
Addendum Finding 70
several goals, policies, and actions to minimize noise impacts to people and the environment in
the vicinity of sources of noise.
Would the Project result in a substantial temporary or periodic increase in ambient noise levels in
the project vicinity above levels existing without the Project?
Construction associated with future projects could cause temporary increases in ambient noise
near work areas, particularly by sensitive receptors. However, it is anticipated that any increase in
noise due to construction traffic would be temporary (i.e., would no longer occur once build-out
of the project area is complete). Further, all construction noise would be restricted by City
ordinance to 7:00 am to 6:00 pm on weekdays. Therefore, the General Plan FEIR concluded that
temporary noise impacts associated with construction-related activities would be less than
significant.
Future construction projects within the City will also be subject to the measures outlined in the City
of Fontana Municipal Code of Ordinances (Chapter 18) and assessed in conjunction with the
City’s review of site-specific noise impact analyses. According to the General Plan FEIR, noise
levels at sensitive receptors would be analyzed on a case-by-case basis and appropriate
mitigation applied to restrict noise levels to acceptable levels. In the event significant impacts are
anticipated, appropriate mitigation would be developed at that time. In addition, the General
Plan Update’s Noise and Safety Element contains several goals, policies, and actions to minimize
noise impacts to people and the environment in the vicinity of sources of noise.
Would the Project expose people residing or working in the project area to excessive noise levels
(for projects 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; or for projects located within the vicinity
of a private airstrip)?

contour for forecast 2020 conditions extends to the City’s western edge. However, the planned
use specified in the General Plan Update for the LA/Ontario area is industrial, which is not
considered a sensitive land use for the 65 dB airport noise zone. Furthermore, the LA/Ontario
International Airport Land Use Compatibility Plan found no residential designations within the
airport noise impact zones in Fontana and identified affected lands as industrial.
In accordance with “Goal 1” of the General Plan Update Noise and Safety Element, no changes
will occur to land uses in areas that are susceptible to a 65 dBA CNEL or greater. This includes
preventing new residents or workers from being exposed to excessive noise levels associated with
air traffic (Ontario International Airport). Therefore, the General Plan FEIR concluded that impacts
associated with aircraft noise would be less than significant.

Analysis of Project
a. Would the project result in 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?
The Project does not propose site-specific development or facilitate future development projects;
rather, it involves amendments to the General Plan Community Mobility and Circulation Element
to comply with AB 98 requirements related to the City’s truck-route network. Specifically, the City’s
existing Truck Route Map (Exhibit 9.7, Truck Routes) would be updated to shift truck traffic away
from residential uses and sensitive receptors, while also clarifying what facilities are officially part
of the City-controlled local truck route network. The Project also proposes minor text changes to
existing policies and actions in the City’s Community Mobility and Circulation Element, as well as
the addition of new policies and actions, to further address AB 98 requirements to provide specific
truck route requirements and avoid residential areas and sensitive receptors, as well as direct the
City towards meeting other AB 98 requirements.
The proposed Project would not result in any modifications to existing land use designations or
modify any existing roadways or roadway classifications or allow for any specific circulation system
projects or improvements. As such, the Project does not include physical modifications of roadway
infrastructure that would require construction activities. As such, there would not be any
construction noise and would result in no impacts related to temporary noise increases
attributable to the Project.
The operations phase of the Project would not result in additional vehicle trips. However, the
Project will result in a rerouting of truck trips which would increase VMT within the City. Truck related
VMT is estimated to be 4,733,518 miles within the City under future conditions without the Project.
The Project’s redistribution of truck trips will increase VMT by 797 miles under future Project
conditions and result in a total of 4,734,315 miles. This increase in VMT represents a 0.02 percent
change in total VMT resulting from the Project (Kittelson & Associates, 2025). The noise levels for
roadways in the project traffic study area were estimated using the Federal Highway
Administration (FHWA) Highway Traffic Noise Prediction Model (RD-77-108). The FHWA model
calculates a predicted noise level through a series of adjustments to a reference sound level
based on a distance of 50 feet from the centerline of the roadway. These adjustments account
for traffic flows, speed, truck mix, varying distances from the roadway, length of exposed roadway,
and noise shielding. The calculations do not take into account the effect of any noise barriers or
topography that may affect ambient noise levels.
Changes in traffic noise levels due to the redistribution of truck trips attributable to Project
operations are summarized in Table 4, Roadway Traffic Noise. This Table accounts for the
estimated changes in traffic noise for future conditions with and without the Project occurring
within the City. As shown in Table 4, some roadway segments have reduced noise exposure levels,
while others have no change or a slight increase in traffic generated noise levels. The highest
increase in noise levels along analyzed roadway segments is 0.2 dBA CNEL. This increase in noise

Community Mobility and Circulation Element Update
Addendum Finding 72
levels is below the minimum change necessary for human hearing to discern a change in noise
levels. A change in noise levels of 1 decibel is perceptible under laboratory conditions whereas a
3 decibel change is the minimum change to be perceptible in outdoor conditions. Because the
Project would result in a maximum increase in traffic noise along all analyzed roadway segments
of less than 3 dB, the Project would not cause a perceptible change in noise levels and
consequently would result in less than significant noise impacts during the operations phase.

b. Would the project result in generation of excessive groundborne vibration or groundborne
noise levels?
The Project does not involve the development of roadway infrastructure and consequently would
not result in vibration associated with construction equipment. Consequently, no vibration impacts
would occur associated with construction equipment.
For the operations phase of the Project, the rerouting of trucks would result in an increase in truck
travel which have the potential to generate vibration. Vehicles traveling on roadways are
supported by flexible suspensions and pneumatic tires, which makes them generally inefficient
sources of ground vibration. However, vibrations can occur when vehicles pass over uneven or
rough pavement. On smooth roadways, continuous traffic tends to produce low, steady levels of
vibration. In contrast, pavement irregularities can cause heavy trucks to generate localized,
intermittent vibration spikes. These spikes are typically short-lived, lasting only a few seconds, or
often just fractions of a second. Because vibration diminishes quickly with distance, the presence
of multiple trucks rarely leads to cumulative increases in ground vibration. Instead, a higher volume
of trucks usually results in more frequent vibration spikes, but not necessarily stronger ones.
Passenger cars, by comparison, produce vibration levels only about one-fifth to one-tenth those
of trucks, and their contribution is typically exceeded by vibrations from heavy truck traffic.
Impacts related to pavement irregularities are uncommon due to the City’s roadway
maintenance programs and vibration dissipates rapidly within short distances from the roadway.
The Project would reroute trucks from noise and vibration sensitive uses such as residential land
uses. The incremental increase in VMT of 0.02 percent due to the Project would not substantially
change the low levels of vibration generated by trucks. In addition, the City’s roadway
maintenance programs minimize any vibration generated by roadway irregularities that may
result in the generation of vibration near vibration sensitive land uses. As such, the Project would
result in less than significant vibration impacts during the operations phase.
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?
As mentioned previously, portions of Fontana lie under the LA/Ontario International Airport flight
path, and the 65 dB CNEL contour for forecast 2020 conditions extends to the City’s western edge.
The Project would result in rerouting of trucks away from noise sensitive land uses and would not
develop noise sensitive land uses such as residential uses. Truck drivers are not considered a noise
sensitive population and roadways are not noise sensitive land uses. As such, the Project would
result in no impacts related to the exposure to people residing or working in the project area to
excessive noise levels from aircraft.
Conclusion
The Project would not result in new or greater noise impacts beyond those identified in the General
Plan FEIR.

General Plan FEIR Conclusions
Would the project induce substantial 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)?
According to the General Plan FEIR, implementation of the General Plan Update could result in
an additional 23,492 households and an additional 40,599 employees within the General Plan
Planning Area. The focus for growth in the General Plan Update is in the Downtown Core of the
City and “Livable Corridors” as described in Chapter 14 - Downtown Area Plan of the General
Plan. The General Plan Update would not designate formerly undeveloped lands needing major
infrastructure expansions (e.g., water, sewer, wastewater) for development. Instead, the General
Plan Update has been developed to 1) accommodate anticipated growth in existing developed
areas that are adequately served by infrastructure, 2) revive underutilized parcels and uses, and
3) preserve and enhance residential opportunities and options within the City.
Due to the focused nature of the General Plan Update on the Downtown Core and Livable
Corridors and the fact that no infrastructure improvements are proposed for the areas where new
residential development would occur, the General Plan Update is predicted to accommodate
anticipated population growth within the City in an orderly manner. The Housing Element
establishes an overall development capacity for the City and serves as a policy guide for
determining the appropriate physical development and character of the City. In addition, goals
and policies related to population and housing in the General Plan Update were developed to
be consistent with and complement the strategies, principles, goals, and policies contained in the

2014 – 2021 Housing Element. Therefore, the General Plan FEIR concluded that potential impacts
would be less than significant.
Would the project displace substantial numbers of existing housing, necessitating the construction
of replacement housing elsewhere?
The General Plan Update would not result in the direct displacement or demolition of residential
structures because it does not authorize specific construction projects, development plans, or
other land-altering activity. While the Update could result in indirect impacts by establishing land
use policies that provide incentives for private redevelopment initiatives in the Downtown Core
and Livable Corridors, the Downtown Area Plan designates land for high-density, transit-oriented
housing that accommodates and encourages development of housing under State Housing
Element Law. Therefore, the General Plan FEIR concluded that there would be no significant
impact related to the reduction of substantial numbers of existing housing necessitating the
construction of replacement housing elsewhere.
Would the project displace substantial numbers of people, necessitating the construction of
replacement housing elsewhere?
The General Plan Update would not result in any direct displacement of substantial numbers of
people because it does not authorize any construction or redevelopment activity that would
displace people. The General Plan Update designates the Downtown Core and Livable Corridors
as land for the development of transit oriented, high-density housing that accommodates and
encourages development of housing for low-income persons. As such, the General Plan FEIR
concluded that there would be no significant impact related to the reduction of substantial
numbers of existing housing, necessitating the construction of replacement housing elsewhere.
Analysis of Project
a. Would the project 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)?
b. Would the project displace substantial numbers of existing people or housing,
necessitating the construction of replacement housing elsewhere?
The Project does not propose site-specific development; rather, it involves amendments to the
General Plan Community Mobility and Circulation Element to comply with AB 98 requirements
related to the City’s truck-route network. Specifically, the City’s existing Truck Route Map (Exhibit
9.7, Truck Routes) would be updated to shift truck traffic away from residential uses and sensitive
receptors, while also clarifying what facilities are officially part of the City-controlled local truck
route network. The Project also proposes minor text changes to existing policies and actions in the
City’s Community Mobility and Circulation Element, as well as the addition of new policies and
actions, to further address AB 98 requirements to provide specific truck route requirements and

avoid residential areas and sensitive receptors, as well as direct the City towards meeting other
AB 98 requirements.
The proposed Project would not result in any modifications to existing land use designations or
modify any existing roadways or roadway classifications or allow for any specific circulation system
projects or improvements. The Project would not modify any General Plan policies or programs
specific to population and housing. The General Plan includes goals, policies, and actions to
reduce impacts associated with increased population and housing within the City. The proposed
amendments to the General Plan Community Mobility and Circulation Element would not conflict
with implementation of these General Plan goals, policies, or actions or the General Plan FEIR
mitigation measures.
Conclusion
The Project would not result in new or greater population and housing impacts beyond those
identified in the General Plan FEIR.
Applicable General Plan FEIR Mitigation Measures: No mitigation measures would be required.

General Plan FEIR Section 5.12, Public Services, Recreation and Utilities, addresses the topics of
utilities and service systems and recreation. For purposes of this analysis, the topics of utilities and
service systems and recreation are discussed below, consistent with the organization of the
General Plan FEIR.
General Plan FEIR Conclusions
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:
• Police protection?
The General Plan continues existing police programs and adds a five year strategic planning
process to align staffing, training, facilities, and equipment with population growth. Police service
needs would increase incrementally, and the City would use development impact fees and
project level review to maintain service ratios, response times, and performance objectives. Any
future construction or expansion of police facilities would undergo City and CEQA review to

identify and mitigate site specific impacts. The General Plan FEIR concluded that with these
policies, actions, and funding mechanisms in place, implementation of the General Plan would
not require new or expanded governmental facilities that cause significant environmental effects,
and impacts would be less than significant.
• Fire protection?
The General Plan maintains and strengthens fire protection through goals, policies, and actions
that continue the City’s partnership with the San Bernardino County Fire Department, monitor
growth to align stations, equipment, training, and resources, require fire hazard reducing designs
in new development, and keep hazard mitigation and emergency programs current. Buildout will
occur over two decades within the existing Fontana Fire Protection District service area, and any
need for new or expanded fire facilities would be addressed incrementally using development
mitigation fees and project level City and CEQA review to identify and mitigate site specific
impacts. Because facility locations and designs are not yet defined, detailed impacts are
speculative, but the plan’s policies and funding mechanisms are designed to maintain
acceptable service levels without causing significant environmental effects. The General Plan FEIR
concluded that impacts related to fire protection facilities would be less than significant.
• Schools?
The General Plan does not propose specific school construction. Fontana Unified and Etiwanda
School Districts monitor growth, update facilities plans, and collect development impact fees
consistent with State law, which is considered sufficient to mitigate school facility impacts from
long term growth. While enrollment and planned housing could create localized needs, the
location, size, and timing of any new or expanded schools are not defined and would be
evaluated through project level City and CEQA review when proposed. The General Plan FEIR
concluded that with these policies, planning practices, and fee programs in place, the project
would not require new or physically altered school facilities that cause significant environmental
effects, and impacts would be less than significant.
Would the Project have sufficient water supplies available to serve the project from existing
entitlements and resources, or are new or expanded entitlements needed?
The General Plan advances integrated water management and conservation through goals,
policies, and actions that promote using the right water for the right use, expanding recycled
water and graywater, and reducing per capita demand. The Fontana Water Company’s 2017
Urban Water Management Plan projects 2035 demand of about 51,211 acre-feet and identifies
reasonably available supplies of about 53,711 acre-feet, with ongoing updates every five years to
track reliability. As individual projects are entitled, water allocation and any required on- or off-site
infrastructure will be addressed through city codes and conditions of approval, with developers
responsible for needed improvements. Based on existing entitlements, planned supplies, and
conservation programs, sufficient water is available to serve buildout under the General Plan, and

new or expanded entitlements are not anticipated. The General Plan FEIR concluded that
impacts related to water supply would be less than significant.
Require or result in the construction of new water treatment facilities or expansion of existing
facilities that the construction of could cause significant environmental effects.
The General Plan does not propose specific construction or expansion of water treatment facilities,
and the City does not own the water supply infrastructure. Most growth is directed to the urban
core where delivery systems already exist, and water purveyors indicate they can serve projected
demand with existing entitlements. While routine maintenance, upgrades, and targeted service
extensions will occur over time through purveyor capital improvement programs, the location and
timing of any new or expanded facilities are not defined and would be evaluated under
applicable environmental review when proposed. Based on these factors, the General Plan FEIR
concluded that the General Plan Update would not require new or expanded water treatment
facilities that cause significant environmental effects, and impacts would be less than significant.
Would the project 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?
Wastewater generated under the General Plan will be served by IEUA Regional Plants 1 and 4,
which have available capacity and operational flexibility to balance flows. While population and
employment are expected to grow through 2035, the plan’s conservation and reuse strategies,
coordination with IEUA, and support for greywater and recycled water are expected to reduce
per capita flows. Project level entitlements will confirm available treatment and collection
capacity and may require developer funded extensions or upsizing where needed, with any site
specific impacts addressed through environmental review. The General Plan FEIR concluded that
based on existing plant capacities, planned coordination, and conservation measures, adequate
wastewater treatment capacity is expected to be available in addition to existing commitments,
and impacts would be less than significant.
Would the project require or result in the construction of new wastewater treatment facilities or
expansion of existing facilities, the construction of which could cause significant environmental
effects?
Construction of new or improvements to existing treatment facilities depends upon the rate and
locations of growth, along with deterioration of aging facilities. The City does not operate the
regional plants, or the wastewater system. As such, the General Plan Update does not include
construction or expansion of any specific wastewater facilities projects. Thus, identifying the
specific location(s) or timing of new or expanded facilities is speculative. Construction of new or
expanded wastewater treatment facilities could result in environmental impacts; however, those
projects would be reviewed for the potential for site specific impacts at that time, and appropriate
mitigation, if necessary, would be applied. Therefore, the General Plan FEIR concluded that no

Community Mobility and Circulation Element Update
Addendum Finding 84
significant impacts are known at this time to occur from the construction of new wastewater
treatment facilities or expansion of existing facilities.
Would project wastewater treatment requirements exceed the requirements of the applicable
Regional Water Quality Control Board?
Wastewater treatment for future development of the General Plan Update will be provided by
the Inland Empire Utilities Agency, which is responsible for complying with Regional Water Quality
Control Board requirements. New projects must meet current building codes and pay
development impact fees that help fund sewer system improvements and expansions. The
General Plan promotes resource efficient systems, recycled water, and graywater where feasible,
and does not include policies that would increase the risk of regulatory exceedances. The General
Plan FEIR concluded that based on these obligations and funding mechanisms, the General Plan
Update would not cause wastewater treatment requirements to exceed RWQCB standards, and
impacts would be less than significant.
Would the project be served by a landfill with sufficient permitted capacity to accommodate the
project’s solid waste disposal needs?
The Mid Valley Landfill is currently permitted through about 2033, and regional trends and updated
projections indicate capacity could extend well beyond that horizon. Although the General Plan
allows for population and employment growth, statewide diversion requirements and local
programs are expected to limit disposal tonnage through recycling and organics diversion, with
City policies aimed at maximizing landfill capacity and maintaining dependable, environmentally
safe service. Because no specific land development is approved by the plan, solid waste
demands will be addressed during project level review and through compliance with the
municipal code and CalRecycle regulations, with developer fees and service arrangements
refined as needed. The General Plan FEIR concluded that based on existing permitted capacity,
ongoing diversion, and General Plan policies, the General Plan Update would be served by
landfills with sufficient capacity, and impacts would be less than significant.
Would the project comply with federal, state, and local statutes and regulations related to solid
waste?
Solid waste collection and disposal in Fontana is provided under established contracts and
permits, with Burrtec collecting municipal solid waste and delivering to the Mid-Valley Landfill,
which is monitored by the County’s Solid Waste Management Division for ongoing compliance
and reporting. The General Plan does not alter these responsibilities and is not expected to impede
compliance with federal, state, or local solid waste statutes and regulations. The General Plan FEIR
concluded that with continued adherence to existing programs and regulatory oversight, impacts
related to regulatory compliance would be less than significant.

Community Mobility and Circulation Element Update
Addendum Finding 85
Would the project require or result in the construction of new storm water treatment drainage
facilities or expansion of existing facilities, the construction of which could cause significant
environmental effects?
The General Plan does not change drainage patterns or approve specific stormwater projects.
Instead, it emphasizes low impact development and green infrastructure, continued
implementation of the City’s Water Quality Management Plan and MS4 requirements, and code
updates to promote infiltration, permeable surfaces, and landscaped stormwater features. Any
future extensions or upgrades to storm drain facilities will be identified through the City’s Master
Plan of Drainage, development review, and the Capital Improvement Program, with developers
funding required improvements and projects subject to applicable environmental review. The
General Plan FEIR concluded that with these policies, programs, and regulatory requirements in
place, the General Plan Update would not require new or expanded stormwater treatment or
drainage facilities that cause significant environmental effects, and impacts would be less than
significant.
Would the project include recreational facilities or require the construction or expansion of
recreational facilities which might have an adverse physical effect on the environment?
The City’s park standard is 5 acres per 1,000 residents. With a 2035 population forecast of 269,066,
the need is about 1,345 acres, and the City already has roughly 1,621 acres of parks and public
use land, which meets the standard. The General Plan does not authorize specific new recreation
facilities; proposed trail concepts, such as completing the San Sevaine Trail and exploring an
Eastside Trail, would be advanced as separate projects with funding, design, and project level
environmental review. Because existing acreage satisfies the performance standard and any
future trail construction would undergo appropriate review, the General Plan FEIR concluded that
the General Plan Update would not require new or expanded recreational facilities that cause
significant environmental effects, and impacts would be less than significant.
A project is considered to have a significant impact if the project increases 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.
The City collects Quimby Act parkland or in-lieu fees from new residential subdivisions and
supplements park funding through development impact fees, grants, joint-use partnerships, and
other sources, while encouraging private open space in large projects. The General Plan adds
policies to maintain parks to a high standard, ensure walking and biking access, expand trails,
update the Parks, Recreation, and Trails Master Plan on a regular cycle, and establish a Parks
Foundation to support improvements and programming. With these funding mechanisms,
maintenance commitments, and programmatic policies in place, increased use of neighborhood
and regional parks as the population grows is not expected to cause or accelerate substantial
physical deterioration. The General Plan FEIR concluded that recreation impacts would be less
than significant.

The Project does not propose site-specific development; rather, it involves amendments to the
General Plan Community Mobility and Circulation Element to comply with AB 98 requirements
related to the City’s truck-route network. Specifically, the City’s existing Truck Route Map (Exhibit
9.7, Truck Routes) would be updated to shift truck traffic away from residential uses and sensitive

receptors, while also clarifying what facilities are officially part of the City-controlled local truck
route network. The Project also proposes minor text changes to existing policies and actions in the
City’s Community Mobility and Circulation Element, as well as the addition of new policies and
actions, to further address AB 98 requirements to provide specific truck route requirements and
avoid residential areas and sensitive receptors, as well as direct the City towards meeting other
AB 98 requirements.
The proposed Project would not result in any modifications to existing land use designations or
modify any existing roadways or roadway classifications or allow for any specific circulation system
projects or improvements. The Project would not modify any General Plan policies or programs
specific to public services, recreation, and utilities and service systems. As discussed, the Project
does not propose any development. Further, the Project involves a citywide redistribution of truck
trips on City roadways; the Project would not create new truck trips within the City or region. As
such, the Project would not increase the population of residents or workers in Fontana requiring
the provision of additional public services, recreation, and utilities and service systems beyond
existing conditions. The General Plan includes goals, policies, and actions to reduce impacts
associated with increased population and the provision of public services, recreation, and utilities
within the City. The proposed amendments to the General Plan Community Mobility and
Circulation Element would not conflict with implementation of these General Plan goals, policies,
or actions or the General Plan FEIR mitigation measures.
Conclusion
The Project would not result in new or greater public services, recreation, and utilities and service
systems impacts beyond those identified in the General Plan FEIR.
Applicable General Plan FEIR Mitigation Measures: No mitigation measures would be required.

The City certified the General Plan FEIR before the above checklist item (b) was added to the
State CEQA Guidelines and prior to VMT becoming the required CEQA metric instead of Level of

is addressed in the General Plan FEIR’s Transportation section.
General Plan FEIR Conclusions
Would the project conflict with an applicable plan, ordinance, or policy establishing measures of
effectiveness for the performance of the circulation system, taking into account all modes of
transportation including mass transit and non-motorized travel and relevant components of the
circulation system, including, but not limited to, intersections, streets, highways, and freeways,
pedestrian and bicycle paths, and mass transit?
The General Plan FEIR concluded that the General Plan Update’s Community Mobility and
Circulation Element is consistent with State, regional, and local multimodal policies and plans,
including the SCAG 2016-2040 Regional Transportation Plan/Sustainable Communities Strategy
(RTP-SCS) and the City’s Active Transportation Plan (ATP), and is designed to expand transit and
active transportation while reducing per-capita VMT. The Community Mobility and Circulation
Element includes Goals, Policies, and Actions intended to connect neighborhoods and City
destinations by expanding transportation choice, consistent with current State planning practices
as regulated by the California Complete Streets Act (AB 1358), the Sustainable Communities and
City of Fontana | Addendum to the General Plan FEIR for the
Community Mobility and Circulation Element Update
Addendum Finding 90
Climate Protection Act (SB 375), the Global Warming Solutions Act (AB 32), and SB 743. Each of
these state regulations seeks to reduce transportation’s impact on the environment by increasing
multi-modal travel and reducing the average distance needed to travel for common functions.
In addition, policies in the General Plan update will result in future projects in the City, particularly
commercial and residential, integrating with pedestrian and bicycle networks adjacent and
nearby to project locations, and allocating the necessary space within project boundaries to
accommodate this pedestrian and bicycle infrastructure.
To reduce dependency on the automobile, the General Plan Update adds two new Walkable
Mixed-Use (WMXU) land use definitions that are designed to promote pedestrian- and bicycle-
friendly development, increase housing diversity, increase transit use, and ensure economic
vitality in the downtown and along important corridors. The WMXU definitions encourage infill
development on vacant parcels and enhance community character. Accordingly, the Update
would not conflict with applicable plans, ordinances, or policies establishing measures of
effectiveness for the circulation system.
Estimates of VMT produced by development in the City of Fontana and its sphere of influence
area have been derived using the San Bernardino Transportation Analysis Model (SBTAM) for
conditions based on the current General Plan and for conditions based on the General Plan
Update. The resulting data, summarized in Table 5.13-6 of the General Plan FEIR, indicates that the
SBTAM estimates that both the current General Plan and the General Plan Update result in more
daily trips, more VMT, and higher VMT per capita when compared to existing conditions. However,
the SBTAM data also indicates that the General Plan Update results in fewer trips and less total
VMT in comparison to the current General Plan. The General Plan also results in approximately 19
percent lower VMT per capita in comparison to the current General Plan (28.1 vs. 34.7) based on
the SBTAM data. The General Plan Update reduces VMT per capita consistent with State goals
outlined in SB 743. By reducing the amount of travel on a per capita basis, the General Plan
Update is consistent with current State policy and the General Plan FEIR concluded that the
General Plan Update would have a less than significant impact on State and local highways.
Based on the analysis of vehicular traffic, the General Plan Update would result in potentially
significant impacts to the traffic and transportation network as ADT would exceed an established
LOS threshold at the following location, which is forecast to operate at LOS “F” under General Plan
buildout conditions: Citrus Avenue between Arrow Boulevard and Foothill Boulevard. To reduce
traffic volumes on this roadway, potential traffic calming and complete street improvements
could be applied to promote the use of non-vehicular travel. This segment of Citrus Avenue has
been identified in the City’s ATP for the provision of a Class II bike lane. The roadway could also
be modified by prohibiting on-street parking and constructing a raised median to increase the
roadway’s vehicular capacity, thereby improving the roadway LOS. With the implementation of
mitigation measure MM-TRA-1), consisting of traffic calming treatments to reduce traffic volumes
and/or an increase in vehicular capacity obtained by constructing a raised median, the General
Plan FEIR concluded that the impact to this segment of Citrus Avenue would be less than
significant.
City of Fontana | Addendum to the General Plan FEIR for the
Community Mobility and Circulation Element Update
Addendum Finding 91
Would the project conflict with an applicable CMP, including, but not limited to, LOS standards
and travel demand measures, or other standards established by the county congestion
management agency for designated roads or highways?
The General Plan FEIR concluded that the General Plan Update remains consistent with the San
Bernardino County Congestion Management Program (CMP) network and classifications, and all
CMP facilities in Fontana are projected to operate at LOS E or better except Citrus Avenue
between Arrow Boulevard and Foothill Boulevard. At that segment, buildout conditions would
exceed the CMP LOS E standard, constituting a significant impact. The General Plan FEIR
concluded that with implementation of MM-TRA-1 (traffic-calming treatments to reduce volumes
and/or a raised median to increase capacity), the impact on Citrus Avenue would be less than
significant.
Result in a change in air traffic patterns, including either an increase in traffic levels or a change
in location that results in substantial safety risks?
There are no airports within the City. According to the General Plan FEIR, the General Plan Update
would not result in the development of a new airport within the City, or throughout San Bernardino
County, nor will it introduce new land uses that could prevent safety hazards to air traffic. There
are no components of the General Plan that directly apply to air traffic patterns. Impacts from
changes in air traffic patterns will be controlled by compliance with applicable federal, state, and
local regulations.
Should new helipads or heliports be proposed in the future within the planning area, such
developments would be required to be submitted through the City to the County of San
Bernardino for review and action. While not anticipated, any future helipad or heliport project
must comply with the State permit procedure provided by law and with all conditions of approval
imposed or recommended by the Federal Aviation Administration (FAA), by the County of San
Bernardino, and by Caltrans/Division of Aeronautics, in addition to any other local requirements.
As such, the General Plan FEIR concluded that the General Plan Update will result in a less than
significant impact due to a change in air traffic patterns.
Substantially increase hazards due to a design feature (e.g., sharp curves or dangerous
intersections) or incompatible uses (e.g., farm equipment)
Hazards are defined as changes to circulation patterns that could result in unsafe driving or
pedestrian conditions. Future projects under the General Plan Update would not substantially
increase hazards due to design features or incompatible uses and would not introduce design
features incompatible with current circulation patterns. Future development under the General
Plan Update would conform to City and State roadway design standards, be reviewed on a
project-by-project basis and provide any required circulation improvements.
The City periodically monitors LOS, traffic accident patterns, and physical conditions of the existing
street system, and makes improvements to roadways as needed. Additionally, the City requires
development projects to provide circulation improvements to achieve stated City goals and to
City of Fontana | Addendum to the General Plan FEIR for the
Community Mobility and Circulation Element Update
Addendum Finding 92
mitigate to the maximum extent feasible traffic impacts to adjacent land uses and neighborhoods
as well as vehicular conflicts related to a project. There are no components of the General Plan
Update that directly apply to hazards due to design features or incompatible uses. Impacts from
design features or incompatible uses will be controlled by compliance with applicable federal,
state, and local regulations. As such, the General Plan FEIR concluded that the General Plan
Update will result in a less than significant impact due to traffic hazards from a design feature or
incompatible uses from implementation of the General Plan Update.
Result in inadequate emergency access?
Future development would be required to comply with the City’s Fire Code provisions for
adequate emergency access. The General Plan Update does not alter emergency access
standards or impede their implementation. Therefore, the Genera Plan FEIR concluded that the
General Plan Update will result in a less than significant impact to emergency access due to
implementation of the General Plan Update.
Would the project conflict with adopted policies, plans, or programs regarding public transit,
bicycle, or pedestrian facilities, or otherwise decrease the performance of safety of such facilities?
According to the General Plan FEIR, the General Plan Update supports and is consistent with the
City’s adopted transit and active transportation plans, including the 2017 Active Transportation
Plan, and does not include policies that would reduce access to or safety of transit, bicycle, or
pedestrian facilities. The Goals, Policies, and Actions of the General Plan Update have been
formulated to supports the City’s vision to take advantage of more transportation choices, to walk
and bike to nearby parks, schools, and stores, use transit and ride sharing, and drive longer
distances as needed. Therefore, the General Plan FEIR concluded that the General Plan Update
will result in a less than significant impact to policies, plans, or programs regarding public transit,
bicycle, or pedestrian facilities, or performance of safety due to implementation of the General
Plan Update.
Analysis of Project
a. Would the project conflict with a program, plan, ordinance or policy addressing the
circulation system, including transit, roadway, bicycle and pedestrian facilities?
The Project does not propose site-specific development; rather, it involves amendments to the
General Plan Community Mobility and Circulation Element to comply with AB 98 requirements
related to the City’s truck-route network. Specifically, the City’s existing Truck Route Map (Exhibit
9.7, Truck Routes) would be updated to shift truck traffic away from residential uses and sensitive
receptors, while also clarifying what facilities are officially part of the City-controlled local truck
route network. The Project also proposes minor text changes to existing policies and actions in the
City’s Community Mobility and Circulation Element, as well as the addition of new policies and
actions, to further address AB 98 requirements to provide specific truck route requirements and
avoid residential areas and sensitive receptors, as well as direct the City towards meeting other
AB 98 requirements.
City of Fontana | Addendum to the General Plan FEIR for the
Community Mobility and Circulation Element Update
Addendum Finding 93
The Project would not involve any physical modifications to the existing roadway system. A review
of roadway segment operations determined that the proposed truck route map would not worsen
roadway segment operations (i.e., reduce LOS) when compared to the current truck route map
and General Plan buildout conditions. The proposed truck routes would occur along roadways
identified as Major or Primary Highways in the General Plan Community Mobility and Circulation
Element. The General Plan includes goals, policies, and actions to promote multi-modal
transportation, including policies addressing transit, roadway, bicycle, and pedestrian facilities.
The proposed amendments to the General Plan Community Mobility and Circulation Element
would not conflict with implementation of these General Plan goals, policies, and actions. The
Project proposes three minor text changes to existing policies and actions in the City’s Community
Mobility and Circulation Element, and the addition of four new policies and actions related to
truck routes and avoiding residential and sensitive uses in order to address AB 98 requirements.
These proposed changes are unrelated to goals, policies, and actions designed to promote multi-
modal transportation. The Project proposes changes to existing policies and actions and the
addition of new policies and actions to meet the City’s goods movement needs while avoiding
residential areas and sensitive receptors.
The proposed Project would not result in any modifications to existing land use designations or
modify any existing roadways or roadway classifications or allow for any specific circulation system
projects or improvements. As such, the proposed truck route map would not physically alter or
interfere with transit, roadway, bicycle, and pedestrian facilities.
b. Would the project conflict or be inconsistent with CEQA Guidelines section 15064.3,
subdivision (b)?
CEQA Guidelines section 15064.3 establishes vehicle miles traveled (VMT) as the primary metric for
evaluating transportation-related environmental impacts under CEQA. This Addendum does not
need to include an analysis of VMT because the General Plan FEIR was certified before VMT
became the required CEQA metric in evaluating transportation impacts. Nonetheless, the
following discussion regarding the Project’s potential VMT impacts is included for informational
purposes.
A VMT analysis was conducted to determine if the rerouted truck trips associated with the
proposed truck route map would alter VMT under near- or long-term conditions, as documented
in the Truck Route Update Recommendations Memorandum prepared for the proposed Project
(Kittelson & Associates, 2025). While the City of Fontana has prepared Traffic Impact Analysis (TIA)
Guidelines for Vehicle Miles Traveled (VMT) and Level of Service Assessment (City of Fontana,
2020), the City’s guidelines are limited to land use projects and do not outline methodologies and
VMT impact thresholds for transportation projects such as the proposed Project. Therefore, the
VMT analysis relied on guidance published by the Governor’s Office of Land Use and Climate
Innovation (LCI) in its Technical Advisory on Evaluating Transportation Impacts in CEQA (LCI, 2018).
According to LCI, if a transportation project would likely lead to a measurable and substantial
increase in vehicle travel, the lead agency should conduct an analysis assessing the amount of
vehicle travel the project will induce. The VMT analysis examined the potential for the Project to
City of Fontana | Addendum to the General Plan FEIR for the
Community Mobility and Circulation Element Update
Addendum Finding 94
lead to additional vehicle travel on the roadway network (known as induced vehicle travel),
resulting in a net increase in VMT.
The VMT analysis included a review of short-term shifts in VMT, calculated based on anticipated
rerouted truck trips due to the proposed truck route map. The Truck Route Update
Recommendations Memorandum concludes that the truck route map update would not result in
significant short-term changes in citywide VMT. The memorandum also explored the potential for
long-term increases in VMT, which are tied to vehicle travel that is induced due to increased
vehicular capacity, or increases in land use development resulting from significant infrastructure
improvements. Consistent with LCI’s guidance, it was concluded that since the updated truck
route map is not increasing capacity or expanding the network, but rather modifying the
designated network of roads that existing truck traffic must follow between their destinations, the
proposed Project is not anticipated to result in long-term increases in VMT.
c. Would the project substantially increase hazards due to a geometric design feature (e.g.,
sharp curves or dangerous intersections) or incompatible uses (e.g., farm equipment)?
d. Would the project result in inadequate emergency access?
The Project does not propose site-specific development; rather, it involves amendments to the
General Plan Community Mobility and Circulation Element to comply with AB 98 requirements
related to the City’s truck-route network. Specifically, the City’s existing Truck Route Map (Exhibit
9.7, Truck Routes) would be updated to shift truck traffic away from residential uses and sensitive
receptors, while also clarifying what facilities are officially part of the City-controlled local truck
route network. The Project also proposes minor text changes to existing policies and actions in the
City’s Community Mobility and Circulation Element, as well as the addition of new policies and
actions, to further address AB 98 requirements to provide specific truck route requirements and
avoid residential areas and sensitive receptors, as well as direct the City towards meeting other
AB 98 requirements.
The proposed Project would not result in any modifications to existing land use designations or
modify any existing roadways or roadway classifications or allow for any specific circulation system
projects or improvements. As such, the Project would not increase hazards due to a geometric
design feature or incompatible uses. Similar to existing conditions, emergency vehicles would not
be subject to the Truck Route Map. Neither the existing General Plan Community Mobility and
Circulation Element nor the City’s Local Hazard Mitigation Plan identify evacuation routes. The
LHMP states that interstates serve as major emergency response and evacuation routes in the
City. The proposed amendments to the General Plan Community Mobility and Circulation Element
would not designate new or alter existing emergency vehicle or evacuation routes. Emergency
evacuation routes would continue to be identified at the time of an emergency in c oordination
with emergency responders with major roadways and interstates serving as primary evacuation
routes. The proposed amendments to the General Plan Community Mobility and Circulation
Element would further support and facilitate goods movement and are not anticipated to
increase congestion on designated truck routes that could interfere with the City’s emergency
City of Fontana | Addendum to the General Plan FEIR for the
Community Mobility and Circulation Element Update
Addendum Finding 95
response or evacuation procedures. Similar to existing conditions, trucks would be required to yield
the right-of-way to emergency vehicles in compliance with the California Vehicle Code. As such,
the Project would not result in inadequate emergency access.
The Project would maintain the broader multi-modal framework established in the Fontana
Forward General Plan Update 2015–2035, which would contribute to reduced automobile trips
and VMT. The Project does not propose modifications to existing land use designations, does not
propose site-specific development, and does not authorize or facilitate future development
projects. Further, the Project would not create new truck trips within the City or region; rather, the
updates to the Truck Route Map would identify specific routes existing trucks within the City would
be required to utilize when traveling within the City.
The General Plan includes goals, policies, and actions to promote multi-modal transportation. The
proposed amendments to the General Plan Community Mobility and Circulation Element would
not conflict with implementation of these General Plan goals, policies, or actions or the General
Plan FEIR mitigation measures, nor would the Project conflict with other adopted plans such as the
ATP or SCAG RTP/SCS. In addition, the Project proposes changes to existing policies and actions
and the addition of new policies and actions to meet the City’s goods movement needs while
avoiding residential areas and sensitive receptors.
Conclusion
The Project would not result in new significant impacts or a substantial increase in the severity of
previously identified significant impacts relative to transportation beyond those identified in the
General Plan FEIR.
Applicable General Plan FEIR Mitigation Measures: No mitigation measures are required.

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

The City certified the General Plan Final FEIR before the above checklist items were added to the
State CEQA Guidelines. However, the topic of tribal cultural resources is addressed in General Plan
Final FEIR Section 5.4, Cultural Resources. For purposes of this analysis, tribal cultural resources are
evaluated in Section 3.5, Cultural Resources, consistent with the organization of the General Plan
FEIR.

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?
X
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?
X
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 or ongoing impacts
to the environment?
X
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?

The City certified the General Plan FEIR before the Wildfire checklist item was added to the State
CEQA Guidelines. Wildfire hazards are addressed in General Plan FEIR Section 5.7, Hazards and
Hazardous Materials. For this analysis, wildfire is evaluated within the Hazards and Hazardous
Materials environmental analysis, consistent with the organization of the General Plan FEIR.

4 ADDENDUM FINDING
As detailed herein, on the basis of substantial evidence in the light of the whole record, a
Subsequent or Supplemental EIR is not required for the proposed Community Mobility and
Circulation Element Update because none of the criteria requiring such a document under Public
Resources Code Section 21166 or State CEQA Guidelines section 15162 are met.
The Community Mobility and Circulation Element Update would result in no new significant
impacts that were not analyzed in the General Plan FEIR, nor would the proposed Project cause
a substantial increase in the severity of any previously identified significant impacts. The potential
impacts associated with the proposed Project would either be the same or less than those
described in the General Plan FEIR. In addition, there are no substantial changes to the
circumstances under which the proposed Project would be undertaken that would result in new
or more severe environmental impacts than previously addressed in the General Plan FEIR, nor has
any new information regarding the potential for new or more severe significant environmental
impacts been identified. Therefore, in accordance with Section 15164 of the State CEQA
Guidelines, this Addendum to the previously certified General Plan FEIR has been prepared for the
proposed Community Mobility and Circulation Element Update. In taking action on any of the
Project, the decision-making body must consider the whole of the data presented in the General
Plan FEIR and this Addendum.
