AUTHORITY FOR REPORT
City of Fontana April 27, 2026
Engineer’s Report for Local Lighting Maintenance District No. 3 www.FinanceDTA.com

I AUTHORITY FOR REPORT
This report is prepared pursuant to the direction of the City of Fontana and in compliance with the requirements of Article 2, Chapter 3, Section 22623 of the Streets and Highways Code, State of California (Landscaping and Lighting Act of 1972) and Article XIIID added to the California Constitution in November 1996 through the passage of Proposition 218 by voters of the State of California. These Constitutional provisions affect the procedural and approval requirements for the levy of assessments. Among other things, the requirements provide that assessed parcels of real property must receive a special benefit from assessments. Assessments are also subject to majority protest requirements . These requirements apply, unless an assessment district meets certain exemptions set forth in Proposition 218 and described below.

The following assessments are exempt from the procedures and approval process of Article XIIID of the California Constitution (Proposition 218); A. Any assessment imposed exclusively to finance the capital costs or maintenance and/or operation expenses for sidewalks, streets, sewers, water, flood control, drainage systems or vector control; or
B. Any assessment imposed pursuant to a petition signed by the persons owning all of the parcels subject to the assessment at the time the assessment is initially imposed.

The City of Fontana Local Lighting Maintenance District No. 3 (Hunter's Ridge) qualifies as an existing assessment exempt from Proposition 218 under exemption "B" described above in that the assessment district was originally formed and the assessment was imposed pursuant to the district was consented to by all of the persons owning all of the parcels subject to the assessment at the time the assessment was initially imposed. The proposed assessments for the 2026-2027 Fiscal Year for Local Lighting Maintenance District No. 3 fall within this exemption because they are merely the annual levy for assessments previously consented to by property owners.

In calculating the assessment for Fiscal Year ("FY") 2026-2027, this report examines the current fiscal year’s financial obligations.

This report is organized into the following sections:

Section I – Authority For Report;
Section II – General Description;
Section III – Plans and Specifications;

METHOD OF APPORTIONMENT OF

ASSESSMENT SPREAD
City of Fontana April 27, 2026
Engineer’s Report for Local Lighting Maintenance District No. 3 www.FinanceDTA.com

VI METHOD OF APPORTIONMENT OF ASSESSMENT SPREAD
The Hunter's Ridge Specific Plan is a multi -use residential development which includes single-family dwelling units and a 3.55-acre commercial site. Areas not to be developed or improved and dedicated to the City or the Etiwanda School District or Caltrans will not be assessed for maintenance costs.

The determination of benefit takes into consideration the following:

1. The purpose of lighting is to provide a safety improvement to Hunter's Ridge Specific Plan area.

2. The maintained lighting benefits all dwelling units in the Hunter's Ridge Specific Plan as well as the commercial site.

3. All single-family dwelling units benefit equally.

4. Commercial acreage is given a benefit surcharge of 4.2 times the assessment per acre based on an equivalent of 4.2 dwelling units to the acre.

The maintenance district will provide for funding a portion of the maintenance costs of lighting facilities deemed to be a fair share of contribution.

Maintenance expenses in excess of the "fair share" contribution shall be funded by a regional lighting district which may be established in the future to include neighboring properties that will share in the benefit of the improvements and facilities.

Formula for Assessment:

A = Assessment per dwelling unit [1]
L = Number of single-family dwelling units not in the estate area M = Number of Multi-family dwelling units not in the estate area P = Number of estate dwelling units
C = Commercial units
Estimated 2026-2027 Assessment: $35,790
C(4.20A) + L(1.0A) +M(0.8A) +P(1.5A) = $35,790

3.55(4.20A) + 1,580(1.0A) + 0(.8A) + 0(1.5A) = $35,790

14.91(A) + 1,580(A) + 0(A) + 0(A) = $35,790
A = $22.44 per unit
[1] The 2026-2027 maximum assessment is $30.92, an increase of $0.61 (2%) over the prior year. 590

SUBJECT:
2026 Action Plan; Substantial Amendments to 2025-2029 Consolidated Plan and 2025 Action Plan RECOMMENDATION:

1. Adopt the 2026 Action Plan.

2. Adopt the Substantial Amendment to the 2025-2029 Consolidated Plan.

3. Adopt the Substantial Amendment to the 2025 Action Plan.

COUNCIL GOALS:
· Increase citizen involvement by seeking community input. · Practice sound fiscal management by producing timely and accurate financial information. · Practice sound fiscal management by pursuing grant opportunities. · Concentrate on Inter-governmental relations by pursuing financial participation from county, state and federal governments.
· Concentrate on Inter-governmental relations by advocating Fontana's position in regional, state, and federal organizations.

DISCUSSION:

Each year, The US Department of Housing and Urban Development (HUD) requires the submission of a One-Year Action Plan that describes planned projects along with one-year goals and budgets for the CDBG, HOME and ESG during the upcoming program year. The draft 2026 Action Plan represents the second-year program as described in the 2025-2029 Consolidated Plan. The draft document submitted for consideration fulfills HUD requirements.

Per the City’s Citizen Participation Plan (CPP), a Substantial Amendment to a Consolidated Plan is required when a Strategic Plan goal is added or removed and a Substantial Amendment to an Action Plan is required when a new activity is added. A Substantial Amendment to the 2025-2029 Consolidated Plan and the 2025 Action Plan are necessary because the City has identified a new goal it wishes to address throughout the Consolidated Plan cycle, and a new activity it would like to add to the Action Plan.

One-Year Action Plan (2026-2027)
The draft Action Plan covers the period of July 1, 2026, to June 30, 2027. It outlines the one-year City of Fontana Printed on 5/7/2026Page 1 of 3

goals and budgets for the CDBG, HOME and ESG programs, and the planned projects to address the priority needs and goals identified in the Consolidated Plan.

If additional funds become available during the program year from unanticipated increases in appropriations, savings from completed projects or dropped projects, the City will use those funds for the rental acquisition and rehabilitation program without amending the Action Plan.

This year, the City received $1,917,147 for CDBG, $575,759.69 for HOME, and $170,763 for ESG funds from HUD. In addition, the City has $4,451,494.91 in carryover HOME funds. These funds will be utilized for various rental housing projects including the CourtPlace Apartment project.

The following CDBG projects are included in the draft FY26 Action Plan:

Activity Budget
Fair Housing Services $30,000
Affordable Rental Housing Development $346,145.55
Preservation of Affordable Housing $900,000

Executive Summary
AP-05 Executive Summary - 24 CFR 91.200(c), 91.220(b)
Introduction
The 2026 Action Plan is the City of Fontana’s Annual Plan for the investment of annual allocations of Community Development Block Grant (CDBG), Home Investment Partnerships (HOME) and Emergency Solutions Grant (ESG) funds from the U.S. Department of Housing and Urban Development (HUD) during this fiscal year. These grant programs are consistent with HUD’s national strategy to provide decent housing opportunities, a suitable living environment, and economic opportunities, particularly for people with low- and moderate-income.

In consideration of finite grant resources, the goals and projects within this Action Plan outline the areas and population segments with the greatest level of need for a particular program or activity and intends to invest grant resources in high leverage opportunities where data suggests the City will be able to maximize the impact of every dollar. The Action Plan utilizes the priority needs identified in the 2025 – 2029 Consolidated Plan process, which identified the City’s priority needs, including the rationale for establishing allocation priorities and specific measurable goals to be addressed during the five-year period.

Within the 2026 Action Plan, the City proposes the following activities:

The high priority needs for Fontana include:

Describe coordination with the Continuum of Care and efforts to address the needs of homeless persons (particularly chronically homeless individuals and families, families with children, veterans, and unaccompanied youth) and persons at risk of homelessness San Bernardino County’s homeless Continuum of Care (CoC) is comprised of a network of public, private, faith-based, for-profit, and non-profit service providers who utilize several federal, state, and local resources to provide services for homeless people. The region’s municipalities, including the City of Fontana, also provide resources for services that assist the homeless and those at risk of becoming homeless. The non-profit and faith-based community plays a key role in the current CoC system.

Hundreds of agencies throughout the County provide programs ranging from feeding the homeless on the street to creating permanent supportive housing opportunities. These services are available to homeless families with children, and individuals. The non-profit and faith-based community also serves special needs populations, such as victims of domestic violence, veterans, the disabled and youth.

Explain how federal funds will leverage those additional resources (private, state and local funds), including a description of how matching requirements will be satisfied To address housing and community development needs in Fontana and maximize the effectiveness of available funds, the City will leverage its CDBG and HOME entitlement grants with a variety of funding resources. The City’s former Redevelopment Agency was the primary non-federal source of leveraged funds. With the elimination of the City’s Redevelopment Agency, the City’s ability to leverage federal funds has been substantially reduced. The City and its development partners will continue to seek new opportunities to leverage federal funds, such as the Low-Income Tax Credit program and U.S.

Matching Requirements
HOME:

HUD requires that the City provide a 25 percent match for their HOME annual allocation. In accordance with 24 CFR 92.222, satisfying the distress criteria established by the HOME Program regulations are provided a match reduction. The match reductions are granted due to fiscal distress, severe fiscal distress, and Presidential disaster declarations. When a local jurisdiction meets one of the distress criteria, it is determined to be in fiscal distress and receives a reduction of match. The City of Fontana does not qualify for a match reduction from HUD in FY 2026. Any funds that are used in a HOME activity in excess of the required match will be documented by the City and reported to HUD as part of the Consolidated Annual Performance and Evaluation Report (CAPER) each year.

ESG:

HUD requires the City provide 100 percent match for its total expenditures. The City requires the ESG subrecipient provide match from its own resources in the form of cash and from qualified non-cash sources. The City provides match for all Administrative costs incurred from qualified sources.

If appropriate, describe publicly owned land or prope rty located within the jurisdiction that may be used to address the needs identified in the plan
Fontana will comply with new State requirements under AB1486 and AB1255 to inventory and support developers to access and utilize surplus municipal and state l and for the construction of affordable housing. If such sites are identified, the City will consider the use of HUD funding or other resources to assist with site preparation and/ or development. At this time, no publicly owned land or property is expected to be used to address the needs in this plan, unless the City addresses ADA Transition Plan needs with CDBG funds.

Introduction
To address the high priority needs identified in the Strategic Plan to the 2025-2029 Consolidated Plan, the City of Fontana will invest CDBG, HOME, and ESG funds in projects that preserve affordable housing, provide fair housing services, provide services to low- and moderate-income residents, provide public services to low- and moderate-income residents, prevent homelessness, preserve neighborhoods, and improve public facilities and infrastructure. Together, these projects will address the housing and community development needs of Fontana residents-particularly those residents residing in the low- and moderate-income CDBG Target Areas.

Describe the reasons for allocation priorities and any obstacles to addressing underserved needs Based on the Strategic Plan, the City is allocating 100 percent of its 2026 CDBG funds (excluding Program Administration) to projects and activities that benefit low- and moderate-income people. The primary obstacles to meeting the underserved needs of low- and moderate-income people include lack of funding from federal, state, and other local sources and the high cost of housing that is not affordable to low-income people. Since housing continues to be the greatest need, the City will be designating most of its allocation to address housing needs and therefore not be investing in projects addressing Public Facilities and Infrastructure Improvements needs. The City will continue investing 2026 CDBG funds in projects that provide neighborhood services for low- and moderate-income people and those with special needs, and projects that prevent homelessness.

Description of the geographic areas of the entitlement (including areas of low-income and minority concentration) where assistance will be directed The City has identified LMI Areas target areas where some CDBG funds will be invested. Most CDBG funds will benefit individuals and households citywide. Infrastructure and public facility improvement and public safety projects will be focused on areas with a concentration of residents with low and moderate incomes throughout the City. Housing, public service and homeless assistance will be made available to income-qualified households throughout the City.

Rationale for the priorities for allocating investments geographically Based on the Strategic Plan, the City is allocating 100 percent of its non-administrative CDBG funds and 100 percent of its non-administrative HOME investment partnership funds for program year 2024 to projects and activities that benefit low- and moderate-income people. While the City targets public facility activities in eligible areas, it does not target specific neighborhoods with concentrated investment and instead evaluates funding on a citywide basis when determining eligibility. The City is not requesting approval of a Neighborhood Revitalization Strategy Area as part of this Plan.

Affordable Housing
AP-55 Affordable Housing – 91.220(g)
Introduction
The 2025-2029 Strategic Plan provides the framework for investing CDBG and HOME funds in Fontana. Affordable housing is a high priority need and in FY26 it will be addressed by the Affordable Rental Housing Development and Preservation of Affordable Housing activities.

Expand the Supply of Affordable Housing
The most common housing problems in the City impacting households with income at or below 80 percent AMI are housing cost burden greater than 30 percent of income followed by overcrowding and severe overcrowding. HUD CHAS data for shows in 2020 nearly 60 percent of households in this income range experience a housing cost burden, while almost five percent are living in overcrowded and severely overcrowded conditions. This includes 6,810 owner and 6,535 renter households that are cost burdened.

Overcrowding and severe overcrowding affects 3,845 households comprised of 2,680 renter households and 1,165 owner households.

Extremely low - and low-income households with one or more housing problem are presumed to b e unstably housed, meaning they are at risk of falling into homelessness. Those with one or more housing problem at this income level are highly sensitive to adverse events. The greatest concentrations of unstably housed households are among small related renter households with a housing cost burden greater than 30 percent of their income, and single family renter households living in overcrowded conditions.

There are 4,580 renter households who earn less than or equal to 50 percent AMI and are severely cost burdened, in 2020 according the CHAS data. Of these households:
- 2,465 are small related households with four or fewer members - 950 are large related households with five or more members - 770 are elderly households with one or more members over aged 62 and older - 395 are other households
These extremely low- and low-income households are considered the most at risk of becoming Preserve the Supply of Affordable Housing
The age and condition of Fontana housing stock is an important indicator of potential rehabilitation needs.

Housing over 30 years of age can be presumed to need some form of major rehabilitation, such as roof replacement, foundation work and plumbing systems. Housing over 20 years of age will generally exhibit deficiencies in terms of paint, weat herization, heating / air-conditioning systems, hot water heaters and finish plumbing fixtures. Housing values in Fontana have increased significantly over a relatively short period of time. Longtime homeowners, especially the elderly and disabled, are more likely to have fixed and limited incomes and may have difficulty maintaining their homes. 677
City of Fontana - 31 - 2026 Annual Action Plan

Thirty-two percent of housing units were constructed in or before 1979. About 42 percent of owner- and renter-occupied housing was built 30 to 40 years ago, between 1980 and 1999. There are 14,920 households with at least one member over the age of 62 and 7,115 of whom have household incomes at or below 80 percent AMI, according to 2016-2020 CHAS data. There are approximately 9,474 people aged 18 to 64 with disabilities, according to 2016-2020, ACS five-year estimates. These households may be presumed to have fixed incomes. It is reasonable to anticipate a significant number of housing units in need of repair and a significant number of households need financial assistance to complete those repairs.

Preservation of the physical and functional integrity of existing housing units occupied by low- and moderate-income households is a cost-effective way to invest limited resources to retain existing housing units that are already affordable to low- and moderate-income households in the community.

Addressing substandard housing conditions through housing preservation activities provide that all economic segments of the community have the means to ensure that their property meets local standards and that all Fontana residents have the opportunity to live in decent housing.

AP-60 Public Housing – 91.220(h)
Introduction
There is no public housing located within the City of Fontana.

Actions planned during the next year to address the needs to public housing Public housing needs are addressed by the Housing Authority of the County of San Bernardino.

Actions to encourage public housing residents to become more involved in management and participate in homeownership
To encourage public housing residents to become more involved in the management of public housing units, HACSB has developed a Resident Advisory Board (RAB) made up of participants from its Term- Limited Lease Assistance Program, Project Based Voucher Program, VASH, and the Tenant-Based Voucher Program. The RAB is tasked with discussing critical issues, like policy changes, program participant outreach efforts and messaging, that affect residents and program participants.

The HACSB offers several ongoing programs to help residents become more involved in management and participate in homeownership. HACSB offers a Family Self-Sufficiency (FSS) program for its residents, which allows participants to save a portion of their income in escrow toward the family’s departure from subsidized housing.

AP-65 Homeless and Other Special Needs Activities – 91.220(i) Introduction
The City of Fontana has identified the prevention and elimination of homelessness and provisions of public services to residents as high priority needs in the 2025-2029 Consolidated Plan. The City will allocate 92.5 percent of its ESG resources to providing homeless assistance in the City and approximately 86 percent of its CDBG public service cap (15 percent of the total allocation) to the public safety program uniquely tailored to engage and protect Fontana’s homeless residents and the remainder of the allocation will be used to provide recreational service to non-homeless elderly residents.

Describe the jurisdictions one -year goals and actions for reducing and ending ho melessness including reaching out to homeless persons (especially unsheltered persons) and assessing their individual needs.

The City of Fontana’s goal of providing public services and the associated public safety project, the FPD MET reaches out to unhoused homeless residents, assesses their needs, and helps to connect them with appropriate resources. The MET provides balanced community-oriented policing in parts of the City with a high concentration of unhoused people. These residents are highly transient, have had varied experiences with authority figures, and are uniquely vulnerable to crime. During MET patrols, officers engage people experiencing unhoused homelessness, and when appropriate, connect them with the services needed. This is sensitive and intensive work, which requires a high level of effort. It can take many engagements before an unhoused individual is ready to receive services. This specialized team provides an invaluable service to the community it serves by providing consistent personal contact with the residents and unsheltered individuals. They create relationships with the community that would not have been achieved with a standard patrol unit that rotates personnel on a regular basis.

Analysis of available data and consultation with organizations providing services for special needs populations revealed a high need for a range of additional services including, but not limited to, those concerned with developmentally disabled adults. The City’s policy for its new rental housing construction program includes a requirement to set aside a minimum number of units exclusively set aside for persons with disabilities. Any new rental project will comply with Title VIII of the Civil Rights Act of 1968 as amended, including Public Law 90-234.

Addressing the emergency shelter and transitional housing needs of homeless persons For program year 2026, The City will provide a continuum of services including emergency shelter, interim housing and permanent supportive housing for individuals experiencing homelessness. The City combines safe housing with supportive services through service coordination. The City’s PATH program supports participants in transitioning from homelessness to stable, long -term housing. The City will continue to use state fundi ng to support the operations of emergency shelter and interim housing programs that serve homeless persons.

City of Fontana - 34 - 2026 Annual Action Plan

Helping homeless persons (especially chronically homeless individuals and families, families with children, veterans and their families, and unacco mpanied youth) make the transition to permanent housing and independent living, including shortening the period of time that individuals and families experience homelessness, facilitating access for homeless individuals and families to affordable housing units, and preventing individuals and families who were recently homeless from becoming homeless again During program year 2026 the City will direct ESG and state funds such as the Family Homelessness Challenge grant funds to provide rapid rehousing, rental assistance, emergency shelter, and permanent supportive housing services to households experiencing homelessness, including supporting households living in emergency shelter, to transition as quickly as possible to permanent housing. It is anticipated that ESG funds will provide approximately four households with rapid rehousing assistance.

Helping low -income individuals and families avoid becoming homeless, especially extremely low-income individuals and families and those who are: being discharged from publicly funded institutions and systems of care (such as health care facilities, mental health facilities, foster care and other youth facilities, and corrections prog rams and institutions); or, receiving assistance from public or private agencies that address housing, health, social services, employment, education, or youth needs The County in collaboration with the CoC maintains Discharge Coordination Policies for the systems of care it administers, such as discharge from the Corrections, Foster Care, and the Mental Health systems. The City supports the CoC’s advocacy for development of consistent policy implementation by hospital administrators for best practices such as recuperative care, and co-location of health services near affordable housing developments.

During the program year 2026 the City will direct ESG and state funds to provide homelessness prevention, rapid rehousing, emergency shelter, and case management services to help households at risk of falling into homelessness avoid that experience if possible.

Discussion
With limited ESG and CDBG resources available, the City is investing ESG funds through the grants made to qualified homeless services providers to offer to person living in Fontana one or more of the following: street outreach, emergency shelter, rapid re-housing, and homelessness prevention.

Additionally, the City is investing general funds through the Police Department budget to provide MET Team officers that will connect unsheltered homeless individuals and families with emergency shelter, transitional housing, and permanent housing opportunities, as well as other services to address special needs such as drug and alcohol rehabilitation and mental health services.

AP-75 Barriers to Affordable Housing – 91.220(j)
Introduction
A barrier to affordable housing is a public policy or nongovernmental condition that constrains the development or rehabilitation of affordable housing, such as land use controls, property taxes, state prevailing wage requirements, environmental protection, cost of land and availability of monetary resources. The City of Fontana works to remove barriers to affordable housing and the financial impact of efforts to protect public health and safety by taking actions to reduce costs or provide offsetting financial incentives to assist in the production of safe, high quality, affordable housing. Barriers to affordable housing are distinguished from impediments to fair housing choice in that barriers are lawful and impediments to fair housing choice are usually unlawful.

According to the City’s 2021-2029 Housing Element, one of the major barriers to housing choice in Fontana and the region more broadly is the lack of sufficient housing affordable to a variety of income levels. While much of this is due to market and environmental constraints that are beyond the control of the City to address, the City’s land use and zoning regulations, especially parking requirements, development fees, local processing and permit procedures, and infrastructure costs, may have contributed to new housing development not keeping pace with population growth.

Actions it planned to remove or ameliorate the negative effects of public policies that serve as barriers to affordable housing such as land use controls, tax policies affecting land, zoning ordinances, building codes, fees and charges, growth li mitations, and policies affecting the return on residential investment The City’s Housing Element includes a Housing Plan with four broad goals and various supporting policies, programs, and actions for addressing the City’s housing needs, including the following:

Goal #1: Adequate housing to meet the needs of all residents in Fontana

1. Provision of Adequate Sites to Meet Regional Housing Needs Assessment Goals

2. Rezone Parcels to R-4/R-4 Overlay to Accommodate RHNA Growth Need for Low and Very Low-Income Households

3. Rezone Parcels to R5 to Accommodate RHNA Growth Need for Low and Very Low-Income Households

4. Proactively Coordinate with Property Owners to Encourage the Development of Affordable Housing in Fontana

5. Encourage the Development of Housing Units for Low-, Very Low-, and Extremely Low-Income Levels

6. Annual Monitoring of Housing Production

7. Compliance with State Density Bonus Law

8. Manufactured and Modular Housing

9. Infill Housing Program

10. Accessory Dwelling Unit Construction

11. Accessory Dwelling Units Monitoring Program

12. Conversion of Existing, Non-Permitted Accessory Dwelling Units

13. Farmworker and Employee Housing Act Compliance
682
City of Fontana - 36 - 2026 Annual Action Plan

14. Amend Fontana Zoning Code for a Variety of Housing Types

15. Minimum Lot Sizes in Multifamily Zones

16. Replacement Housing for Non-vacant Sites

17. Lot Consolidation Program for Small Sites

Goal #2: A high standard of quality in existing affordable housing stock

1. Monitoring of "At-Risk" Housing Units

2. Code Enforcement for Residential Properties

3. Housing Unit Revitalization Program

4. Resources Conservation Practices

5. Promotion of Green/Sustainable Development Practices

6. Water and Sewer Service Purveyors

Goal #3: Housing development that is not affected by governmental constraints

1. Expedited Permit Processing and other Procedures

2. Review Parking Requirements

3. Monitoring Development Fees

4. SB 35 Streamlining Procedures

Goal #4: Affirmatively further fair housing in Fontana

1. Affordable Housing Online Resource Website

2. Participation and Support of Regional Fair Housing Efforts

3. Family Self-Sufficiency Program

4. Mental Health Services Program

5. Supportive/Transitional Housing Facilitation

6. Domestic Violence Services Program

7. Community Assistance Program

8. Anti-Poverty Program

9. Housing Referral and Information Services

10. Community and Stakeholder Engagement

11. Housing for Persons with Developmental Disabilities

12. Affirmatively Further Fair Housing

The City’s 2025 Analysis of Impediments to Fair Housing identified housing issues, conditions which restrict fair housing choice or access to opportunity, and goals for addressing them. The following specific actions to address each fair housing issue identified in the assessment:
- Lending Discrimination: Hispanic and African American individuals or families experienced lower loan approval rates than other groups when purchasing or refinancing a home in the City. African Americans continue to have the lowest approval rates for home purchase loans and Hispanics have the lowest approval rat e for refinance loans. To address this issue, the City will monitor HMDA data and affirmatively market the availability of first-time homebuyer assistance programs that provide down payment assistance to low - and moderate-income homebuyers. The City will also provide written outreach to lending institutions regarding the City’s commitment to eliminate racial discrimination in lending patterns; encourage attendance of all staff at Inland Fair Housing 683
City of Fontana - 37 - 2026 Annual Action Plan

and Mediation Board (IFHMB) workshops; and provide flyers regarding FTHB education, including IFHMB’s FAQ on the City’s website.

- Discrimination Based on Disability : Complaints received by the City’s contracted fair housing service provider based on disability continue to be the leading basis of all discriminatio n complaints. This demonstrates a lack of understanding and sensitivity of the fair housing rights of the disabled by the housing industry. To address this issue, the City will continue working with their contracted fair housing service provider to provide recommendations of properties believed to be discriminatory in their practices as information is received; facilitate accessibility reviews of multi-family properties; and distribute design and construction information to all who inquire about building permits.

- Fair Housing Education : There is an increasing number of fair housing complaint intakes performed by the City’s contracted fair housing service provider. Furthermore, their interactions with housing providers and housing seekers during workshops have demonstrated a lack of understanding of both Federal and State fair housing laws. To address this issue, the City will continue working with IFHMB to provide opportunities for conducting Fair Housing workshops in the City and providing IFHMB outreach materials as a part the City’s newsletter and utility bill mailings. The City will also encourage collaboration with local realtors; provide recurring education to members of the Inland Valleys Association of Realtors; offer no-cost Fair Housing workshops; and develop a fair housing FAQ for the City’s website.

- Transit Access: Omnitrans does not have a bus route connecting the public transit system to the Falcon Ridge and Summit shopping centers located on either side of Summit Avenue off the 1 - 15 freeway in North Fontana. This is a major employment center that includes shops, restaurants, and stores such as Target, Kohls, Staples, and Stater Brothers. Additionally, bus route 82 is the southwestern-most as well as the northernmost bus route in the City, runn ing east-west in the south for miles along Jurupa Avenue, and north along Sierra Avenue from Jurupa up to the 210 freeway. An extension of this line or another route along Slover Avenue just south of the 10 freeway would connect residents to two of the top 10 employers in Fontana that are not located within one-half mile of a bus stop. To increase transit access, the City will continue to build and expand public transportation opportunities servicing the Falcon Ridge / Summit Avenue Job Center and the Southwest Industrial / Jurupa Hills Job Centers.

- Reasonable Accommodation: A significant portion of the housing in Fontana was built before the advent of modern accessibility standards, thus modifications to homes may be needed to allow access by a disabled person. To address this issue and comply with Federal and State housing laws (SB 520), the City will analyze existing land use controls, building codes, and permit and processing procedures to determine constraints they impose on the development, maintenance, and improvement of housing for persons with disabilities. Based on its findings, the City will develop a policy for reasonable accommodation to provide relief from Code regulations and permitting procedures that have a discriminatory effect on housing for individuals with disabilities.

The procedures shall include the process for requesting accommodation, a timeline for processing 684
City of Fontana - 38 - 2026 Annual Action Plan

and appeals, criteria for determining whether a requested accommodation is reasonable, and ministerial approval for minor requests.

- Public Investment in Specific Neighborhoods: Neighborhoods in the center of the city lack access to economic and educational opportunities. To address this issue, the City of Fontana has identified a total of 8 sites to accommodate future housing in a R/ECAP area. The 8 sites estimate a total of 216 potential units, 151 of which are estimated to be affordable to lower income households. The City recognizes the unique needs of R/ECAP areas will schedule at least two (2) targeted outreach meetings in the designated R/ECAP area to better understand community needs as they are related to housing. The City will work with interested developers to support affordable housing options in the R/ECAP area with a focus on quality design and access to economic and educational resources.

- Availability of Affordable Housing: The need for affordable housing outpaces the supply of housing in Fontana. To address this issue, the City will seek to increase affordable housing options for lower income residents across the City. The City’s sites strategy will take an aggressive approach to promote affordable housing in higher resource areas and will meeting with local and regional stakeholders to increase the feasibility and development of affordable housing. The City will streamline affordable housing projects, and provide additional incentives when funding is available. Additionally, the City will work with developer to potentially utilize the existing Inclusionary Ordinance.

- Access to Proficient Education : Disparities in ac cess to high quality schools disproportionately impacts protected class groups in the city, in large part due to limited affordable housing options near high-performing schools. To address this issue, the City has identified parcels adjacent to local schools for housing opportunities. Additionally, with the Fontana Unified School Districts support, parcels owned by FUSD have been identified near schools for rezone to increase density. The City will support housing opportunities adjacent to educational insti tutions and schools in order to decrease challenges related to access and commuting. The City will partner with FUSD annually to gather insight via community outreach about key housing and economic needs of FUSD families and students.

Dear City Clerk Key, Director Nevins, and Planner Quintanilla:

I am writing on behalf of Supporters Alliance for Environmental Responsibility (“SAFER”) regarding the Hilton Industrial Facility Project (Master Case No. 18-000053; Tentative Parcel Map No. 18-000005 (TPM No. 19950); Design Review No. 18-000010) (“Project”), which proposes the development of two industrial commerce center facilities totaling 71,985 square feet, located north of Hilton Drive and west of Hemlock Avenue, in the City of Fontana (“City”). With this letter, SAFER appeals to the Fontana City Council the Planning Commission’s March 17, 2026 decision to approve the Hilton Industrial Facility based on a California Environmental Quality Act (“CEQA”) Class 32 Categorical Exemption for the Project.

The Planning Commission’s March 17, 2026, decision to approve the Project should not be upheld because the Project does not qualify for a Class 32 Categorical Exemption under CEQA. SAFER therefore respectfully requests that the City rescind the Project approvals, conduct an initial study, and prepare either a mitigated negative declaration or environmental impact report to analyze and mitigate the Project’s environmental impacts.

SUBJECT: Response to SAFER Appeal Letter for Master Case No. 18 -000053 (Hilton Industrial Facility)

Dear Salvador:

This letter has been prepared per the City’s request for Lilburn Corporation to provide a response to the March 25, 2026 appeal letter from Lozeau Drury LLP ’s requesting the Planning Commission’s denial of the project. SAFER requests that the City prepare an Initial Study to analyze and mitigate the Project’s environmental impacts.

The CE Justification analysis documents that the Project is exempt from the California Environmental Quality Act (CEQA) under the Class 32 Categorical Exemption (CE) set forth in CEQA Guidelines Section 15332. The Justification Memorandum in the City’s files for the Project, provides an introduction, project description, and evaluation of the Project’s consistency with the requirements for a Class 32 CE. The Memorandum further evaluates whether any of the exceptions to categorical exemptions set forth in CEQA Guidelines Section 15300.2 apply to the Project.

CEQA Guidelines Section 15332 states that a Class 32 CE applies when:

a) The project is consistent with the applicable general plan designation and all applicable general plan policies as well as with applicable zoning designation and regulations.
b) The proposed development occurs within city limits on a project site of no more than five acres substantially surrounded by urban uses.
c) The project site has no value as habitat for endangered, rare or threatened species. d) Approval of the project would not result in any significant effects relating to traffic, noise, air quality, or water quality.
e) The site can be adequately served by all required utilities and public services.

As documented in the CE Justification, the Project is an allowable use under the City of Fontana General Plan (General Plan) land use designation of Light Industrial (I-L) and is zoned as West End Specific Plan (BP3). According to the General Plan, business parks, research and 697

development, technology centers, corporate and support office uses, clean industry, supporting retail uses, truck and equipment sales and related services are allowed. Warehouses that are designed in ways that limit off-site impacts are also permitted. The Proposed Project therefore has been evaluated as such in the General Plan EIR.

The Project Site is surrounded by a Target warehouse to the north, Vision Communications and Open Door Solutions to the east, Southern California Edison to the west, and a Service Partners, a building supply warehouse to the south. Surrounding uses predominantly consist of industrial uses.

The land uses and zoning designations surrounding the Project Site are as follows:

North: Uses to the north are designated Light Industrial (L-I) and zoned West End Specific Plan (BP3).

East: Uses to the east are designated Light Industrial (L-I) and zoned West End Specific Plan (BP3).

South: Uses to the south are designated Light Industrial (L-I) and zoned West End Specific Plan (BP3).

West: Uses to the west are designated Light Industrial (L-I) and zoned West End Specific Plan (BP3).

The analyses prepared for the subject project concludes that the Project meets all criteria shown above to qualify for an Infill Exemption and no significant impacts that could not be mitigated to levels of less than significant were identified . Based on the CE Justification Memo as well as expert review of the Proposed Project, substantial evidence supports the City’s determination that the Project is categorically exemption under CEQA Guidelines section 15332.

If you should have any questions or require additional information, please do not hesitate to give us a call.

Sincerely,

As analyzed above, the project is consistent with applicable General Plan designation and policies and zoning designation and regulations. Thus, the project would meet Criterion (a) requirements.

Criterion (b) The proposed development occurs within city limits on a project site of no more than five acres substantially surrounded by urban uses.

The Project Site is a 4.0-acre parcel located along the north side of Hilton Drive between Redwood Avenue and Hemlock Avenue , west of Sierra Avenue within the City of Fontana. As shown on Figure 2, the site is within an industrial area and adjacent to industrial uses.

The project location within the City and the size of the Project Site provide consistency with Criterial (b) requirements.

Criterion (c) The project site has no value as habitat for endangered, rare or threatened species.

A Biological Resources Assessment Letter Report dated September 2025, was prepared for the Proposed Project by Jennings Environmental LLC . (Jennings) (Appendix A). The findings are summarized herein.

Jennings conducted the general reconnaissance survey within the Project Site to identify the potential for the occurrence of special status species, vegetation communities, or habitats that could support special status wildlife species. The surveys were conducted on foot, throughout the Project Site on September 10, 2025.

No rare, State and/or federally -listed threatened or endangered species are documented/or expected to occur within the Project site. Additionally, no plant species with the CNPS California Rare Plant Rank (CRPR) of 1 or 2 were observed on -site or documented to occur on-site in the relevant databases. No other sensitive species were observed within the project area or buffer area.

The Project Site is highly disturbed. The habitat on-site is ruderal/disturbed vegetation with gravel surfaces. The site offers no suitable habitat for any rare sensitive species including listed species.

Therefore, no further surveys are required. Although the site is highly disturbed, there is some habitat within the Project site and adjacent area that is suitable for nesting birds in general. In general, the following condition of approval , in accordance with the Fontana General Plan Final Environmental Impact Report (August 10, 2018) Mitigation Measure BIO-3 and as recommended in the 2025 Biological Resources Assessment, nesting bird surveys shall be implemented prior to construction if construction occurs during the period of February 1 through September 15.

Mitigation Measure BIO -3 states that the City of Fontana shall require that all future project applicants prepare a Biological Assessment in conjunction with a project -level analysis and that the requirements of the Biological Assessment shall be a condition of approval of the individual development project.

Accordingly, the following shall be implemented prior to construction:

Prior to initial grading or clearing of areas of suitable habitat within the Planning Area (e.g., a vacant site with a landscape of grassland or low -growing, arid scrub vegetation or agricultural use or vegetation), a qualified biologist shall conduct a pre -construction 709
Hilton Drive Warehouses Project
February 3, 2026

Page 12 ends

survey, in accordance with the CDFG Staff Report on Burrowing Owl Mitigation, to determine the presence or absence of burrowing owl within the proposed area of impact.

Results of surveys, including mitigation recommendations (i.e. a Burrowing Owl Mitigation and Monitoring Report) shall be incorporated into the project -level CEQA compliance documentation.

Construction grading/clearing of areas of suitable habitat should occur between September 1 and January 31 to avoid impacts to breeding owls. If occupied burrows are discovered, they shall not be removed during nesting season [February 1 through August 31), unless a qualified biologist can determine that either the owls have not laid eggs or are incubating eggs, or that any young from the burrows are able to forage independently.

If initial grading is scheduled to occur during nesting season, the following measures shall be implemented.

If removal of occupied burrows is necessary, passive relocation outside of nesting season shall be implemented under the supervision of the qualified biologist. This shall include covering/excavation of burrows and installation of one-way doors as necessary. One-way doors will allow owls inside the burrow to exit but not allow them to re -enter. The biologist shall wait a minimum of one week before the burrow may be excavated to allow the owls time to leave the area.

The Project Site is located within the developed western area of the City and is mostly surrounded by urban land uses. There are no sensitive natural communities on the Project Site. No endangered, rare, or threatened species, as defined in CEQA Guidelines Section 15380, are expected to inhabit the site. The site is not within the designated critical habitat of any species.

As such, t he Project Site has no value as habitat for endangered, rare , or threatened species.

Thus, the Proposed Project would meet Criterion (c) requirements.

Criterion (d) Approval of the project would not result in any significant effects relating to traffic, noise, air quality, or water quality.

TRAFFIC

A Traffic Memorandum dated December 9 2025 , was prepared for the Proposed Project by Gandini Group, Inc. (Appendix B). The findings are summarized herein.

Trip Generation

As stated in the Traffic Memorandum, the Proposed Project is forecast to generate approximately 99 daily vehicle trips, including 9 vehicle trips during the AM peak hour and 11 vehicle trips during the PM peak hour which equates to approximately 150 daily PCE trips, including 13 PCE trips during the AM peak hour and 15 PCE trips during the PM peak hour.

Subject to verification by the City Traffic Engineer, the project does not appear to contribute to unique existing or proposed traffic conditions in the project vicinity to warrant further evaluation. 710
Hilton Drive Warehouses Project
February 3, 2026

Page 13 ends

Therefore, the project does not warrant the preparation of a transportation impact study with LOS analysis based on the City-established screening criteria and LOS impacts may be presumed to be negligible.

Vehicle Miles Traveled (VMT) Screening Criteria

The City TIA Guidelines identify screening criteria for certain types of projects that typically reduce VMT and may be presumed to result in a less than significant VMT impact. In accordance with the City’s project type screening, projects generating less than 500 daily vehicle trips may be presumed to have a less than significant VMT impact.

The Proposed Project satisfies the City -established vehicle miles traveled (VMT) screening criteria for projects generating less than 500 daily trip . The Proposed Project is forecast to generate approximately 99 daily vehicle trips, including 9 vehicle trips during the AM peak hour and 11 vehicle trips during the PM peak hour which equates to approximately 150 daily PCE trips, including 13 PCE trips during the AM peak hour and 15 PCE trips during the PM peak hour ..

Therefore, based on the City’s guidelines, the project would be screened out from a VMT analysis based on the daily trip thresholds and is anticipated to have a less than significant VMT impact.

NOISE

A Noise Impact Analysis, dated December 23, 2025, was prepared for the Proposed Project by Ganddini Group, Inc. (see Appendix C for report). The unit of measurement used to describe a noise level is the decibel (dB)
Construction Noise On-site

The City of Fontana has set restrictions to control noise impacts associated with the construction of the Proposed Project. According to Section 18-63 of the city’s Municipal Code, Construction or repairing of buildings or structures, construction activity is limited: between the hours of 7:00 a.m. and 6:00 p.m. on weekdays and between the hours of 8:00 a.m. and 5:00 p. m. on Saturdays except in the case of urgent necessity. Project construction noise levels are, therefore, considered exempt from municipal r egulation if activities occur within the hours specified in the City of Fontana Municipal Code, Section 18-63 of 7:00 a.m. to 6:00 p.m. on weekdays and between the hours of 8:00 a.m. to 5:00 p.m. on Saturdays. However, neither the General Plan nor the Municipal Code establish numeric maximum acceptable construction source noise levels at potentially affected receivers for CEQA analysis purposes. Therefore, a numerical construction threshold based on Federal Transit Administration (FTA) Transit Noise and Vib ration Impact Assessment Manual is used for analysis of daytime construction impacts, as discussed below. According to the FTA, local noise ordinances are typically not very useful in evaluating construction noise. They usually relate to nuisance and hours of allowed activity, and sometimes specify limits in terms of maximum levels, but are generally not practical for assessing the impact of a construction project.

Project construction noise criteria should account for the existing noise. the FTA considers a daytime exterior construction noise level of 80 dBA Leq(8-hour) for noise sensitive residential land uses, 85 dBA Leq(8 -hour) for commercial uses, and 90 dBA Leq(8 -hour) for industrial uses.

Construction noise would affect adjacent light industrial/warehouse land uses.

Project construction noise levels at nearby sensitive receptors were calculated using the FTA methodology. Modeled construction noise levels reach up to 70.7 dBA Leq at the property line shared with the industrial warehouse land use to the north, up to 68. 5 dBA Leq at the property 711
Hilton Drive Warehouses Project
February 3, 2026

Page 14 ends

line shared with the industrial land use to the south, and up to 77.9 dBA Leq at the industrial properties located to the east and west. Project construction noise levels will not exceed the FTA 90 dBA Leq (8-hour) construction noise standard for impacts to residential land uses. This impact would be less than significant.

Construction Noise Off-site

Project construction would generate up to 31 employee trips and 12 truck trips per day traveling to and from the project site via Hilton Avenue, Redwood Avenue and Hemlock Avenue to Foothill Boulevard where project trips would result in negligible increases in ambient noise levels. There are existing residential land uses along Redwood Avenue and Hemlock Avenue that would be exposed to these trips. Existing noise levels and existing plus project construction noise levels were calculated using FHWA methodology .

Operational Noise

The Proposed Project is considered an allowed use in accordance with the General Plan and West End Specific Plan standards, and the proposed warehouses are compatible with surrounding industrial developments. Noise generated by the Project would be consist ent with existing industrial noise levels and would occur within an established industrial area. As a result, anticipated warehouse-related noise would not exceed the City’s noise standards and would not introduce a new substantial noise source compared to existing conditions. Impacts would be less than significant.

AIR QUALITY

This analysis is based on the California Emissions Estimator Model (CalEEMod) version 2022 outputs (Appendix D).

Regulatory Requirements

The Project Site is located in the South Coast Air Basin (SCAB). The South Coast Air Quality Management District (SCAQMD) has jurisdiction over air quality issues and regulations within the SCAB. An evaluation of potential air quality impacts related to the Proposed Project (Warehouse Development) was prepared. The CalEEMod recommended by the SCAQMD for all general development projects within the SCAB was used to estimate project emissions.

Operational Emissions

As stated, based on the City of Fontana Traffic Engineering Division Traffic Impact Analysis (TIA) Guidelines for Vehicle Miles Traveled (VMT) and Level of Service (LOS) Assessment, dated October 2020, all truck trips were converted to passenger car equivalents (PCEs) using a 2.0 PCE factor for 2‐axle trucks, 2.5 for 3‐axle trucks, and 3.0 for 4‐ and more axle trucks. The Proposed 712
Hilton Drive Warehouses Project
February 3, 2026

Page 15 ends

Project is anticipated to generate 20 PCE trips in the a.m. peak hour, 23 PCE trips in the p.m. peak hour, and 195 daily PCE rips. The Proposed Project’s operation and construction emissions were screened using the California Emissions Estimator Model (CalEEMod) version 2022 prepared in collaboration with the SCAQMD (see Attachment B).

Construction Emissions

CalEEMod was utilized to estimate the on-site and off-site construction emissions. The emissions incorporate Rules 402 and 403 for fugitive dust by default as required during construction. The criteria pollutants screened for include reactive organic gases (ROG), nitrous oxides (NOx), carbon monoxide (CO), sulfur dioxide (SO 2), and fine and respirable particulates (PM 10 and PM2.5). Two of the analyzed pollutants, ROG and NO x, are ozone precursors. These criteria pollutants are key contributors to air qualit y degradation and can have potential significant environmental and public health impacts . Screening for these pollutants helps identify potential air quality impacts to protect public health, and comply with SCAQMD Thresholds.

Construction is anticipated to start late 2026 and end in late 2027. Construction and activities associated with the Proposed Project would have the potential to generate air emissions and toxic air contaminant emissions. The resulting emissions generated during construction and demolition of the Proposed Project are shown in Table 2 and Table 3 below which represent summer and winter conditions respectively.

As shown in Table 2 and 3, both summer and winter construction emissions are below SCAQMD thresholds. The Proposed Project does not exceed applicable SCAQMD regional thresholds during construction activities. Therefore, impacts are considered less than significant.

Operational Emissions

Operational emissions are categorized as energy (generation and distribution of energy to the end use), area (operational use of the project), and mobile (vehicle trips). Operational emissions were estimated using the CalEEMod version 2022 and are listed in Table 4 and 5, below.

As shown, both summer and winter season operational emissions are below SCAQMD thresholds. The Proposed Project would not exceed any SCAQMD thresholds for criteria pollutants during construction (see Table 2, 3). Operational emissions are less than significant and would not result in a cumulatively considerable net increase of any criteria pollutant (see Tables 4 and 5). Therefore, less than significant adverse impacts are identified or anticipated, and no mitigation measures are required.

SCAQMD has developed a methodology to assess the localized impacts of emissions from a Proposed Project as outlined within the Final Localized Significance Threshold (LST) Methodology report; completed in June 2003 and revised in July 2008. The use of LSTs is voluntary, to be implemented at the discretion of local public agencies acting as a lead agency pursuant to CEQA. LSTs apply to projects that must undergo CEQA or the National Environmental Policy Act (NEPA) and are five acres or less. LST methodology is incorporated to represent worst- 714

case scenario emissions thresholds. CalEEMod was used to estimate the on -site and off -site construction emissions. The LSTs were developed to analyze the significance of potential air quality impacts of a project to sensitive receptors (i.e. schools, single family residences, etc.) and provide screening tables for small projects (one, two, or five acres). Projects are evaluated based on geographic location and distance from the sensitive receptor (25, 50, 100, 200, or 500 meters from the site).

For the purposes of a CEQA analysis, the SCAQMD considers a sensitive receptor to be a receptor such as a residence, hospital, convalescent facility or anywhere that it is possible for an individual to remain for 24 hours. Additionally, schools, playground s, childcare centers, and athletic facilities can also be considered as sensitive receptors. Commercial and industrial facilities are not included in the definition of sensitive receptor because employees do not typically remain on-site for a full 24 hours, but are usually present for shorter periods of time, such as eight hours.

The Project Site is approximately 4.0 acres. For a conservative, worst-case analysis, the “5-acre” LSTs were applied, as larger sites correspond to higher screening thresholds. The nearest sensitive receptor is a motel located approximately 100 meters sout heast of the Site, so LSTs were evaluated at this distance. The Proposed Project’s construction and operational emissions with the appropriate LST are presented in Table 6 “Localized Significant Threshold”.

Per LST Methodology, mobile source emissions do not need to be included except for land use emissions and onsite vehicle emissions. It is estimated that approximately 10 percent of mobile emissions will occur on the Project Site.

As shown in Table 6, both construction and operational emissions are well below the applicable thresholds. As such, the potential for adverse health effects is minimal. Therefore, a Health Risk Assessment (HRA) is not required for the Proposed Project. Therefore, no significant adverse air quality impacts are identified or anticipated, and no mitigation measures are required.

WATER QUALITY

A Hydrology Study was prepared for the Proposed Project dated A ugust 16, 2023, revised July 22, 2024 by Land Development Design Company, LLC (LDDC), the results are summarized herein (Appendix E). The Proposed Project would disturb approximately four (4) acres and would therefore be subject to the National Pollutant Discharge Elimination System (NPDES) permit. The State of California is authorized to administer various aspects of the NPDES. Const ruction activities covered under the State’s General Construction permit include the removal of vegetation, grading, excavating, or any other activity that causes the disturbance of one acre or more. The General Construction permit requires recipients to reduce or eliminate non-storm water discharges into stormwater systems, and to develop and implement a SWPPP. The SWPPP is based on the principles of Best Management Practices (BMPs) to control and abate pollutants.

The SWPPP must include BMPs to prevent Pr oject-related pollutants from impacting surface waters.

The RWQCB has issued an area wide NPDES Storm Water Permit for the County of San Bernardino, the San Bernardino County Flood Control District and the unincorporated areas of San Bernardino County. The implementation of NPDES permits ensures that the State and Federal mandatory standards for the maintenance of clean water are met.

The State of California is authorized to administer various aspects of the National Pollutant Discharge Elimination System (NPDES). Construction activities covered under the State’s General Construction permit include removal of vegetation, grading, excava ting, or any other activity that causes the disturbance of one acre or more. Since the Proposed Project would disturb approximately 4.0 acres, it is subject to the NPDES permit requirements. Pursuant to Fontana Municipal Code (FMC) Section 23-516, Compliance with Mandated Best Management Practices, operation of the Proposed Project would be required to comply with applicable BMPs that may include waste storage areas to reduce pollution introduction , outdoor material storage areas to reduce pollution introduction, finish grade of landscaped areas at a minimum of 1-2 inches below top of curb, sidewalk, or pavement, use of efficient irrigation systems and landscape design, water conservation, smart controllers, and source control. Overall, upon compliance with FMC Chapter 23, Article 9, Preventing Discharge of Pollutants into Storm Drains, and implementation of the BMPs, project construction and operations would not result in any significant effects relating to water quality. Therefore, impacts regarding water quality are considered less than significant.

As demonstrated above, approval of the project would not result in any significant effects relating to traffic, noise, air quality, or water quality and therefore Criteria (d) is met.

Criterion (e) The site can be adequately served by all required utilities and public services.

The City of Fontana Public Works Department provides wastewater and stormwater collection services and oversees solid waste collection services (contracted to Burrtec), and the Fontana Water Company provides water services to the Project Site. Southern California Edison and Southern California Gas Company would provide electricity and natural gas services, respectively. Additionally, the project would be served by the Fontana Fire Protection District for fire protection services, and the Fontana Police Department for police protection services.

The Project Site is located within the service area of the Fontana Water Company (FWC) as a division of the San Gabriel Valley Water Company. The Proposed Project would include 716
Hilton Drive Warehouses Project
February 3, 2026

Page 19 ends

connection to existing FWC water mains along Hilton Drive. The Proposed Project would be served by the City of Fontana for sewer service; existing service lines are located in Hilton Drive.

Thus, the site would be adequately served by all required utilities and services and the project would meet Criterion (e) requirements.

The following analysis considers whether exceptions to the Class 32 Categorical Exemption apply:

Exception (a) A categorical exemption shall not be used for a project under Classes 3, 4, 5, 6, and 11, if the project may impact on an environmental resource of hazardous or critical concern where designated, precisely mapped, and officially adopted pursuant to law by federal, state, or local agencies.

The City is proposing a categorical exemption under Class 32 and not Classes 3, 4, 5, 6, or 11.

Therefore, Exception (a) would not apply to the project.

Exception (b) A categorical exemption shall not be used for a project when the cumulative impact of successive projects of the same type in the same place, over time is significant.

For this Exception, that disallows a categorical exemption to be used for a project when the cumulative impact of successive projects “of the same type in the same place over time” has a narrower definition than the broad definition of cumulative impacts a s defined and applied elsewhere in CEQA practice. Further in Robinson v. City & County of San Francisco (2012) 208 Cal.App.4th 950, 958, the court held that the phrase “in the same place” should be interpreted to refer to the area where the environmental impact will occur and that the affected area will depend on the nature of the environmental impact.

The project involves the development of two industrial warehouses. The Project Site is located within a developed area of the City’s west end area consisting predominately industrial uses .

Based on the analysis herein, the project would not considerably contribute to any significant impacts. As such, project impacts are not cumulatively considerable, and Exception Criterion (b) would not apply to the project.

Exception (c) A categorical exemption shall not be used for an activity where there is a reasonable possibility that the activity will have a significant effect on the environment due to unusual circumstances.

This exception applies only when both unusual circumstances and a significant impact as a result of those unusual circumstances are shown. ( Berkeley Hillside Preservation v City of Berkeley “Berkeley Hillside” (2015) 60 Cal.4th 1086, 1104) As the Supreme Court explained in Berkeley Hillside, the City’s determination whether this exception applies involves two distinct questions:
(1) whether the project presents unusual circumstances, and (2) if the project presents unusual circumstances, whether there is a reasonable possibility that a signi ficant environmental impact will result from those unusual circumstances. (60 Cal.4th at 1098.) The City considers the second prong of this two‐part test only if it first finds that some circumstance of the project is unusual. If the City finds that the project does not present unusual circumstances, the exception is inapplicable, and the agency need not reach the second prong of the two‐part test.

717
Hilton Drive Warehouses Project

Here, the City’s determination whether the proposed project presents unusual circumstances involves a factual inquiry under which the City weighs the relevant evidence to determine if those circumstances are unusual in comparison with other projects in the CEQA Guidelines Section 15332. The Proposed Project would not be used for an activity where there is a reasonable possibility that the activity will have a significant effect on the environment due to unusual circumstances and involves construction activities typical for other similar projects in the City that have been approved pursuant to the CEQA Guidelines section 15332 exemption. An example of a similar project approved by the City pursuant to the CEQA Guidelines Section 15332 exemption is the warehouse project (MCN22 -057), which was approved by the Fontana Planning Commission on December 20, 2022.

The summer and winter season operational and construction emissions are below SCAQMD thresholds. The Proposed Project would not exceed any SCAQMD thresholds for criteria pollutants. Additionally, the Proposed Project’s localized emissions are not anticipated to exceed Localized Significance Thresholds because emissions would be temporary, limited in intensity, and would occur over a short duration. Construction and operational activities would comply with applicable air quality regulations and incorporate standard best management practices, which would minimize pollutant concentrations near the Project site. Additionally, the distance to nearby sensitive receptors and prevailing dispersion conditions would reduce the potential for localized air quality impacts. Therefore, localized emissions would remain below significance thresholds.

As such, the Project Site has no value as habitat for endangered, rare, or threatened species.

With implementation of the Conditions of Approval, impacts to biological resources would be less than significant.

The existing noise levels range between 62.9 and 65.6 dBA CNEL and existing plus project construction noise levels would range between 63.2 and 65.7 dBA CNEL. Project construction traffic would result in a less than 1 dB increase along both roadways and wo uld not exceed the applicable FICON noise increase thresholds. Impacts would be less than significant and no mitigation measures are required. The Proposed Project is considered an allowed use in accordance with the General Plan and West End Specific Plan standards. The proposed warehouses show compatibility with the surrounding industrial developments. Therefore, anticipated warehouses noise associated with the project is not expected to exceed the City’s noise standards and would not introduce a new subst antial noise source compared to existing conditions. Impacts would be less than significant.

The Proposed Project satisfies the City -established vehicle miles traveled (VMT) screening criteria for projects generating less than 500 daily trip. The Proposed Project is forecast to generate approximately 99 daily vehicle trips, including 9 vehicle trips during the AM peak hour and 11 vehicle trips during the PM peak hour which equates to approximately 150 daily PCE trips, including 13 PCE trips during the AM peak hour and 15 PCE trips during the PM peak hour..

Therefore, based on the City’s guidelines, the project would be screened out from a VMT analysis based on the daily trip thresholds and is anticipated to have a less than significant VMT impact.

As such, there is no evidence that the Proposed Project will, result in a significant effect on the environment.

Exception (d) A categorical exemption shall not be used for a project which may result in damage to scenic resources, including but not limited to, trees, historic buildings, rock outcroppings, or similar resources, within a highway officially designated as a State scenic highway.

Based on the San Bernardino Countywide Map: NR-3 Scenic Routes & Highways, there are no scenic highways near the Project Site or within the City of Fontana. 6 The closest officially designated or eligible State scenic highway is Lytle Creek Canyon Drive located approximately

6.0 miles to the north in Rancho Cucamonga, San Bernadino County. Given the distance of the Project Site to Lytle Creek Canyon Drive and intervening topography, vegetation, and structures, the project would not be visible. As such, the Proposed Project would have no impact on scenic resources within a State scenic highway and Exception (d) would not apply.

Exception (e) A categorical exemption shall not be used for a project located on a site which is included on any list complied pursuant to Section 65962.5 of the Government Code.

Government Code Section 65962.5 requires the Department of Toxic Substance Control and State Water Resources Control Board to compile and update a regulatory site listing (per the criteria of the Section). The California Department of Health Services is also required to compile and update, as appropriate, a list of all public drinking water wells that contain detectable levels of organic contaminants and that are subject to water analysis pursuant to Health and Safety Code Section 116395. Section 65962.5 re quires the local enforcement agency, as designated pursuant to Section 18051 of Title 14 of the CCR, to compile, as appropriate, a list of all solid waste disposal facilities from which there is a known migration of hazardous waste. The Project Site is not currently listed pursuant to Government Code Section 65962.5 (Cortese List).7 As such, Exception (e) would not apply.

Exception (f) A categorical exemption shall not be used for a project which may cause a substantial adverse change in the significance of a historical resource.

A Cultural Resources Report dated March 2022 were prepared for the Proposed Project by LSA Associates. (Appendix F). The findings are summarized herein.

According to LSA, the cultural resources records search was completed for the project area by the South Central Coastal Information Center (SCCIC) located at California State University, Fullerton. It included a review of all recorded historic and prehistoric archaeological sites within one mile of the project. Data from the SCCIC indicate there have been 23 cultural resource studies previously conducted within one mile of the proposed project, three of which included the entirety of the project area. Although no cultural resources are documented within the project area, 21 built environment resources are recorded within one mile. The nearest is approximately 100 feet south of the project. Only one of the resources is listed in the BERD (36 -015392). No prehistoric resources are documented within a mile.

A cultural resources records search, additional research, and a field survey were conducted for the project area. No cultural resources are documented within the project parcel and none was

identified by the survey. No prehistoric resources were documented within a mile, and sensitivity for in situ undocumented subsurface resources is low. Therefore, no further investigation or archaeological monitoring is recommended. However, it is recommended that archaeological monitoring consistent with the City of Fontana’s standard condition for cultural resources be implemented. Below is the City of Fontana’s standard condition for cultural resources monitoring:

1. Upon discovery of any tribal cultural or archaeological resources, cease construction activities in the immediate vicinity of the find until the find can be assessed. All tribal cultural and archaeological resources unearthed by project construction activities shall be evaluated by the qualified archaeologist and tribal monitor/consultant. If the resources are Native American in origin, interested Tribes (as a result of correspondence with area Tribes) shall coordinate with the landowner regarding treatment and curation of these resources. Typically, the Tribe will request preservation in place or recovery for educational purposes. Work may continue on other parts of the project while evaluation takes place.

Preservation in place shall be the preferred manner of treatment. If preservation in place is not feasible, treatment may include implementation of archaeological data recovery excavation to remove the resource along the subsequent laboratory processing and analysis. All Tribal Cultural Resources shall be returned to the Tribe. Any historic archaeological material that is not Native American in origin shall be curated at a public, non-profit institution with a research interest in the materials, if such an institution agrees to accept the material. If no institution accepts the archaeological material, they shall be offered to the Tribe or a local school or historical society in the area for educational purposes.

Archaeological and Native American monitoring and excavation during construction projects shall be consistent with current professional standards. All feasible care to avoid any unnecessary disturbance, physical modification, or separation of human remains and associated funerary objects shall be taken. Principal personnel shall meet the Secretary of the Interior standards for archaeology and have a minimum of 10 years’ experience as a principal investigator working with Native American archaeological sites in southern California. The Qualified Archaeologist shall ensure that all other personnel are appropriately trained and qualified.

As such, Exception (f) would not apply.

CONCLUSION

As detailed above, construction and operations of the Project meets the five criteria required stipulated in CEQA Guidelines Section 15332 to qualify for a Class 32 CE.

RE: BIOLOGICAL RESOURCES ASSESSMENT LETTER REPORT FOR THE HILTON DRIVE

INDUSTRIAL PROJECT IN THE CITY OF FONTANA, SAN BERNARDINO COUNTY, CALIFORNIA

Dear Ms. Tubbs,
Jennings Environmental was retain ed by Lilburn Corporation (Lilburn) to conduct a Biological Resources Assessment of the proposed Hilton Drive Industrial Project (Project). The survey identified vegetation communities, the potential for the occurrence of special status species, or habitats that could support special status wildlife species, and recorded all plants and animals observed or detected within the Project boundary. This biological resources assessment is designed to address the potential effects of the proposed project on designated critical habitats and/or any species currently listed or formally proposed for listing as endangered or threatened under the federal Endangered Species Act (ESA) and the California Endangered Species Act (CESA) or species designated as sensitive by the California Department of Fish and Wildlife (CDFW) or the California Native Plant Society (CNPS). Information contained in this document is in accordance with accepted scientific and technical standards that are consistent with the requirements of the United States Fish and Wildlife Service (USFWS) and (CDFW).

Project Description and Location

The proposed Project is to develop the 3.37 -acre site with two industrial buildings . Both buildings will have office space, warehouse space , and trucking bays. Additional improvements include parking, landscaping, and lighting.

The Project is generally located in Section 2, Township 1 South, Range 6 West, and is depicted in the Fontana U.S. Geological Survey’s (USGS) 7.5-minute topographic map. More specifically, the project is located within Assessor Parcel Number ( APN) 1110-151-03, within the City of Fontana, San Bernardino County, California. The site is bordered by commercial and industrial uses on all sides, with a Southern California Edison office and storage yard to the west.

Methods

Prior to performing the updated field survey, existing documentation relevant to the Project site was reviewed. The most recent records of the California Natural Diversity Database (CNDDB) managed by CDFW (CDFW 2025), the USFWS Critical Habitat Mapper (USFWS 2025), and the California Native 724
Biological Resources Assessment for Hilton Drive Industrial Project Jennings Environmental, LLC P a g e | 2
Plant Society’s Electronic Inventory (CNPSEI) of Rare and Endangered Vascular Plants of California (CNPS 202 4) were reviewed for the following quadrangles containing and surrounding the Project site: Fontana, Devore, Guasti, and Cucamonga Peak USGS 7.5 -minute quadrangles. The Devore, Guasti, and Cucamonga Peak quads were included in this search due to the site’s proximity to their borders. These databases contain records of reported occurrences of rare, federal- or state-listed endangered or threatened species, California Species of Concern (SSC), or otherwise special status species or habitats that may occur within or in the immediate vicinity of the Project site.

Jennings biologist, Gene Jennings, conducted the general reconnaissance survey within the Project site to identify the potential for the occurrence of special status species, vegetation communities, or habitats that could support special status wildlife sp ecies. The surveys were conducted on foot, throughout the Project site between 0730 and 0830 hours on September 10, 2025 . Weather conditions during the survey included temperatures ranging from 62 – 64 degrees Fahrenheit, with cloudy skies, no precipitation, and 0 to 2 miles per hour winds. Photographs of the Project site were taken to document existing conditions and are included in Attachment B.

Results

Habitat and Wildlife
The habitat on-site consists of disturbed ruderal vegetation and bare gravel ground. The site showed signs of previous development, concrete pads. Additionally, the site is highly disturbed, and soils consist of imported fill material, likely from the surrounding developed sites. T he site is also being maintained through weed abatement (mowing or weed whacking) as eviden ced by the minimal amount of vegetation on -site and dried , broken plant parts. Plant species observed on site are :
tumbleweed (Salsola tragus ), lemon gum (Corymbia citriodora ), telegraphweed (Heterotheca grandiflora), dove weed (Croton setiger), Mediterranean mustard (Hirschfeldia incana), desert poplar (Populus euphratica), and flatspine burragweed (Ambrosia acanthicarpa). None of these plants are documented as rare using the CNPS California Rare Plant Rank (CRPR) of 1 or 2.

Animal species observed or otherwise detected on or in the vicinity of the project site during the surveys included : mourning dove ( Zenaida macroura ), common raven (Corvus corax ), Anna’s hummingbird (Calypte anna), house finch (Haemorhous mexicanus), and house sparrow (Passer domesticus). None of the animal species documented on -site are considered rare, endangered, or threatened.

The Project site is located within a largely developed portion of the City of Fontana. As mentioned above, the site is continually maintained, and portions were previously developed. As such the site offers no habitat for any listed species.

CNDDB Results

According to the CNDDB, CNPSEI, and other relevant literature and databases, 87 sensitive or rare species, 18 of which are listed as threatened or endangered, and 5 sensitive habitats, have been documented in the Fontana, Devore, Guasti, and Cucamonga Peak quads. This list of sensitive species and habitats includes any State and/or federally -listed threatened or endangered species, CDFW-designated Species of Special Concern (SSC) , and otherwise Special Animals. “Special Animals” is a general term that refers to all of the taxa the CNDDB is interested in tracking, regardless of their legal or protection status. This list is also referred to as the list of “species at risk” or “special status species.” The CDFW considers the taxa on this list to be those of greatest conservation need. 725
Biological Resources Assessment for Hilton Drive Industrial Project Jennings Environmental, LLC P a g e | 3

An analysis of the likelihood of the occurrence of all CNDDB -sensitive species documented in the Fontana, Devore, Guasti, and Cucamonga Peak quads is provided in Table 1, in Attachment C. This analysis takes into account species range as well as documentation within the vicinity of the project area and includes the habitat requirements for each species and the potential for their occurrence on the site, based on required habitat elements and range relative to the current site conditions.

According to the databases, no sensitive habitat, including US FWS-designated critical habitat, occurs within or adjacent to the project site.

Designated Critical Habitat and San Bernardino County Biotic Resources Overlay

The site is not located within or adjacent to any USFWS-designated Critical Habitat. No further action is required.

The site is within the identified boundary for burrowing owl on the San Bernar dino County Biotic Resources Overlay. See below for findings related to this species, based on the completed habitat assessment.

Special Status Species Background
Burrowing owl (BUOW) {Athene cunicularia} [State – Candidate Endangered] The BUOW is a state and federal SSC. This owl is a mottled, brownish , sand-colored, dove -sized raptor, with large, yellow eyes, a rounded head lacking ear tufts, white eyebrows, and long legs compared to other owl species. It is a ground-dwelling owl typically found in arid prairies, fields, and open areas where vegetation is sparse and low to the ground. The BUOW is heavily dependent upon the presence of mammal burrows, with ground squirrel burrows being a common choice, in its habitat to provide shelter f rom predators, and inclement weather, and to provide a nesting place.

They are also known to make use of human-created structures, such as cement culverts and pipes, for burrows.

BUOW spends a great deal of time standing on dirt mounds at the entrance to a burrow or perched on a fence post or other low -to-the-ground perch from which they hunt for prey. BUOW frequently hunt by hovering in place above the ground and dropping on their prey from above. They feed primarily on insects such as grasshoppers, June beetles, and moths, but will also take small rodents, birds, and reptiles. They are active during the day and night but are considered a crepuscular owl; generally observed in the early morning hours or at twilight. The breeding season for BUOW is February 1 through August 31. Up to 11, but typically 7 to 9, eggs are laid in a burrow, abandoned pipe, or other subterranean hollows where incubation is complete in 28 -30 days. Young BUO W fledges in 44 days. The BUOW is considered a migratory species in portions of its range, which includes western North America from Canada to Mexico, and east to Texas and Louisiana. BUOW populations in California are considered to be sedentary or locally migratory.

Throughout its range, the BUOW is vulnerable to habitat loss, predation, vehicular collisions, and destruction of burrow sites, and the poisoning of ground squirrels . BUOW has disappeared from significant portions of their range in the last 15 years. The BUOW is listed under the California Endangered Species Act as a candidate species . The BUOW is a migratory bird protected by the international treaty under the Migratory Bird Treaty Act of 1918 and by State law under the California Fish and Game Code (CDFG Code #3513 & #3503.5).

Findings: The conditions present on -site are not suitable for BUOW. California ground squirrels, a burrow surrogate species, were not observed on-site. No evidence of BUOW was found in the survey area. No burrows of appropriate size, aspect, or shape were located and no BUOW pellets, feathers, or whitewash were found. No burrowing owl individuals were observed. Additionally, the site does not contain friable soils , as evidence of gravel and cobble fill was found on-site. These factors preclude this species from the site. Therefore, no further surveys or mitigation measures are required or recommended.

Conclusions and Recommendations

Based on the literature review and personal observations made in the immediate vicinity, no rare, State and/or federally -listed threatened or endangered species are documented/or expected to occur within the Project site. Additionally, no plant species with the CNPS California Rare Plant Rank (CRPR) of 1 or 2 were observed on-site or documented to occur on-site in the relevant databases. No other sensitive species were observed within the project area or buffer area.

The Project Site is highly disturbed. T he habitat on-site is ruderal/disturbed vegetation with gravel surfaces. The site offers no suitable habitat for any rare sensitive species including listed species.

Therefore, no further surveys are required.

Nesting Birds

Although the site is highly disturbed, there is some habitat within the Project site and adjacent area that is suitable for nesting birds in general. In general, the following condition of approval should be implemented prior to construction.

Nesting bird season generally extends from February 1 through September 15 in southern California and specifically, March 15 through August 31 for migratory passerine birds. To avoid impacts to nesting birds (common and special status) during the nesting season, a qualified Avian Biologist will conduct pre ‐construction Nesting Bird Surveys (NBS) prior to Project‐related disturbance to nestable vegetation to identify any active nests. If no active nests are found, no further action will be required. If an active nest is found, the biologist will set appropriate no‐work buffers around the nest which will be based on the nesting species, its sensitivity to disturbance, nesting stage, and expected types, intensity, and duration of the disturbance. The nests and buffer zones shall be field -checked weekly by a qualified biological monitor. The approved no ‐work buffer zone shall be clearly marked in the field, within which no disturbance activity shall commence until the qualified biologist has determined the young birds have successfully fledged and the nest is inactive.

Coding and Terms

E = Endangered T = Threatened C = Candidate FP = Fully Protected WL = Watch List SSC = Species of Special Concern R = Rare

State Species of Special Concern: An administrative designation given to vertebrate species that appear to be vulnerable to extinction because of declining populations, limited acreages, and/or continuing threats. Raptor and owls are protected under section 3502.5 of the California Fish and Game code: “It is unlawful to take, possess or destroy any birds in the orders Falconiformes or Strigiformes or to take, possess or destroy the nest or eggs of any such bird.”

State Fully Protected: The classification of Fully Protected was the State's initial effort in the 1960's to identify and provide additional protection to those animals that were rare or faced possible extinction. Lists were created for fish, mammals, amphibians and reptiles. Fully Protected species may not be taken or possessed at any time and no licenses or permits may be issued for their take except for collecting these species for necessary scientific research and relocation of the bird species for the protection of livestock.

Global Rankings (Species or Natural Community Level):

G1 = Critically Imperiled – At very high risk of extinction due to extreme rarity (often 5 or fewer populations), very steep declines, or other factors.

G2 = Imperiled – At high risk of extinction due to very restricted range, very few populations (often 20 or fewer), steep declines, or other factors.

G3 = Vulnerable – At moderate risk of extinction due to a restricted range, relatively few populations (often 80 or fewer), recent and widespread declines, or other factors.

G4 = Apparently Secure – Uncommon but not rare; some cause for long-term concern due to declines or other factors.

G5 = Secure – Common; widespread and abundant.
? = Uncertainty in the exact status of an element (could move up or down one direction from current rank)

Subspecies Level: Taxa which are subspecies or varieties receive a taxon rank (T-rank) attached to their G-rank. Where the G-rank reflects the condition of the entire species, the T-rank reflects the global situation of just the subspecies. For example: the Point Reyes mountain beaver, Aplodontia rufa ssp. phaea is ranked G5T2. The G-rank refers to the whole species range i.e., Aplodontia rufa. The T-rank refers only to the global condition of ssp. phaea.

State Ranking:

S1 = Critically Imperiled – Critically imperiled in the State because of extreme rarity (often 5 or fewer populations) or because of factor(s) such as very steep declines making it especially vulnerable to extirpation from the State.

S2 = Imperiled – Imperiled in the State because of rarity due to very restricted range, very few populations (often 20 or fewer), steep declines, or other factors making it very vulnerable to extirpation from the State.

S3 = Vulnerable – Vulnerable in the State due to a restricted range, relatively few populations (often 80 or fewer), recent and widespread declines, or other factors making it vulnerable to extirpation from the State.

S4 = Apparently Secure – Uncommon but not rare in the State; some cause for long-term concern due to declines or other factors.

S5 = Secure – Common, widespread, and abundant in the State.

California Rare Plant Rankings (CNPS List):
1A = Plants presumed extirpated in California and either rare or extinct elsewhere. 1B = Plants rare, threatened, or endangered in California and elsewhere. 2A = Plants presumed extirpated in California, but common elsewhere. 2B = Plants rare, threatened, or endangered in California, but more common elsewhere. 3 = Plants about which more information is needed; a review list. 4 = Plants of limited distribution; a watch list.

Threat Ranks:
.1 = Seriously threatened in California (over 80% of occurrences threatened / high degree and immediacy of threat) .2 = Moderately threatened in California (20-80% occurrences threatened / moderate degree and immediacy of threat) .3 = Not very threatened in California (less than 20% of occurrences threatened / low degree and immediacy of threat or no current threats known) 756

TECHNICAL MEMORANDUM

TO: Ms. Cheryl Tubbs | LILBURN CORPORATION

FROM: Perrie Ilercil, Senior Engineer | GANDDINI GROUP, INC.

DATE: December 9, 2025

SUBJECT: Hilton Industrial Facility Project (EST24-00008) Transportation Screening Assessment GGI Project No. 19866

Ganddini Group, Inc. is pleased to provide this Transportation Screening Assessment for the Hilton Industrial Facility project in the City of Fontana. The purpose of this memorandum is to determine if the preparation of a traffic impact analysis with level of service (LOS) analysis or vehicle miles traveled (VMT) analysis is necessary based on the transportation study guidelines and screening criteria established by the City of Fontana. We trust the findings of this analysis will aid the City of Fontana in assessing the project.

PROJECT DESCRIPTION

The 4.01-acre project site (APN: 1110-151-03) is located on the northside of Hilton Drive approximately 950 feet east of Redwood Avenue in the City of Fontana, California. The project site is currently vacant and zoned industrial in the West End Specific Plan.

The proposed project involves the development of two warehouse buildings with a total of 71,985 square feet. Vehicle access for the project site is proposed via two driveways onto Hilton Drive. The proposed site plan is shown in Attachment A

TRIP GENERATION

Table 1 shows the proposed project trips based on trip generation rates obtained from the Institute of Transportation Engineers (ITE) Trip Generation Manual (12th Edition, 2025) for Land Use Code 150 (Warehouse).

Truck Trips

The project industrial trip generation was also calculated in terms of Passenger Car Equivalent (PCE) trips. The percentage of truck trips was obtained from the ITE Trip Generation Manual (12th Edition, 2025). The truck mix by axle type was determined based on recommendations for non-cold storage warehouse from the Warehouse Truck Trip Study Results and Usage, by South Coast Air Quality Management District, July 17, 2014.

Truck trips were converted to PCE trips based on the City of Fontana equivalent factors of 2.0 for 2-axle light-duty trucks, 2.5 for 3-axle medium-duty trucks, and 3.0 for 4+-axle heavy-duty trucks.

Project Trips

As shown in Table 1, the proposed project is forecast to approximately 99 daily vehicle trips, including 9 vehicle trips during the AM peak hour and 11 vehicle trips during the PM peak hour which equates to 758

approximately 150 daily PCE trips, including 13 PCE trips during the AM peak hour and 15 PCE trips during the PM peak hour.

CRITERIA FOR THE PREPARATION OF TRAFFIC IMPACT ANALYSES

The project has been assessed to determine if the preparation of a traffic impact analysis with level of service (LOS) analysis and vehicle miles traveled (VMT) analysis is necessary based on the criteria established as specified in the City of Fontana Transportation Impact Analysis (TIA) Guidelines for Vehicle Miles Traveled (VMT) and Level of Service Assessment (LOS) (October 2020) [“City TIA Guidelines”].

Level of Service Screening Criteria (General Plan Conformity)

As specified in the City TIA Guidelines, the requirement to prepare a transportation impact study with level of service (LOS) analysis should be based on one or more of the following criteria:

 If a project is forecast to exceed the Congestion Management Program (CMP) threshold of 250 two-way peak hour trips, a traffic impact analysis will be required.  If a project is forecast to generate between 100 and 249 two-way peak hour trips, a traffic impact analysis will be required, but the extent of the analysis will be lesser.  If a project generated between 50 and 100 two-way peak hour trips, a focused traffic analysis will be required.
 If a project generates less than 50 peak hour trips, a traffic analysis report shall not be required, and a trip generation memo will be considered sufficient unless the City has specific concerns related to project access and interaction with adjacent intersections.

The project would generate and contribute fewer than 50 peak hour trips to any intersection of two streets designated as Collector or higher on the City’s General Plan circulation system. The project does not propose any deviation from the City’s TIA Guidelines or design standards. Subject to verification by the City Traffic Engineer, the project does not appear to contribute to unique existing or proposed traffic conditions in the project vicinity to warrant further evaluation. Therefore, the project does not warrant the preparation of a transportation impact study with LOS analysis based on the City-established screening criteria and LOS impacts may be presumed to be negligible.

Vehicle Miles Traveled Screening Criteria (CEQA)

The vehicle miles traveled (VMT) screening assessment has been prepared in accordance with City TIA Guidelines, which were developed based on guidance from the Office of Planning and Research (OPR) Technical Advisory on Evaluating Transportation Impacts in CEQA (State of California, December 2018) [“OPR Technical Advisory”]. In general terms, VMT quantifies the amount and distance of automobile travel attributable to a project or region. The OPR Technical Advisory provides technical considerations regarding methodologies and thresholds with a focus on office, residential, and retail developments as these projects tend to have the greatest influence on VMT.

The City TIA Guidelines identify screening criteria for certain types of projects that typically reduce VMT and may be presumed to result in a less than significant VMT impact. To qualify for VMT screening, the project need only satisfy one of the following screening criteria:

759

Ms. Cheryl Tubbs
Hilton Industrial Facility
December 9, 2025

Hilton Industrial Facility
Transportation Screening Assessment
3 19866
 Projects located within a Transit Priority Area (TPA) □ Projects located within one-half mile radius of a major transit stop 1 or high-quality transit corridor2  Projects located within a low VMT area
□ Site location can be verified with the web-based or map-based VMT Screening Tool 3  Project Type Screening
□ Local-serving retail (less than 50,000 square feet)
□ Projects consisting of land uses which by their nature are local-serving  Project Net Daily trips less than 500 ADT
□ Projects consisting of land uses which by their nature are local-serving □ Projects which generate less than net new 500 daily vehicle trips (ADT)

TPA Screening

Projects located within a TPA, defined as within one-half mile of a major transit stop or high-quality transit corridor, may be presumed to result in a less than significant VMT impact absent substantial evidence to the contrary. The City TIA Guidelines note that this screening criteria may not apply if the project has a floor area ratio (FAR) less than 0.75, the project provides more parking than required by the city, the project is inconsistent with applicable Sustainable Communities Strategy (SCS), or the project constructs a smaller number of moderate or high-income residential units than the existing number of affordable residential units.

Based on a review of the San Bernardino County Transportation Authority (SBCTA) VMT Screening Tool, the proposed project is located within a TPA, is consistent with SCS and parking standards and does not displace residential units; however, the project is below the FAR threshold of 0.75. Therefore, the TPA screening criteria is not met.

Low VMT Area Screening

As prescribed in the City TIA Guidelines, the SBCTA VMT Screening Tool was used to assess low VMT area screening for the project. The VMT Screening Tool was developed using the County travel forecasting model to measure VMT performance for individual jurisdictions and for individual traffic analysis zones (TAZs) within the County transportation region. TAZs are geographic polygons similar to census block groups used to represent areas of homogenous travel behavior. Total daily VMT per service population was estimated for each TAZ. This presumption may not be appropriate if the project land uses would alter the existing built environment in such a way as to increase the rate or length of vehicle trips.

Based on the VMT Screening Tool results for the project site, located within TAZ 53716401, the baseline year (2025) VMT per service population for the project TAZ is equal to 53.3 VMT per service population, which is not less than the City-established threshold based on 15 percent below the San Bernardino County regional average baseline (39.0 VMT). Therefore, the project does not satisfy the City-established screening criteria for projects located in a low VMT area.

1 A major transit stop is defined as an existing rail transit station, ferry terminal with bus or rail service, or the intersection of two or more major bus routes with 20-minute or less headways during the peak commute hours (Pub. Resources Code, § 21064.3 and AB2553). 2 Fixed route bus service with less than 15-minute headways during the peak commute hours (Pub. Resources Code, § 21155). 3 The SBCTA VMT Screening Tool was developed from the San Bernardino Transportation Analysis Model (SBTAM) travel forecasting model to measure VMT performance for individual jurisdictions and for individual traffic analysis zones (TAZs). 760

Project Type Screening

The City TIA Guidelines identify the several types of projects that may be presumed to have a less than significant VMT impact as they are local serving and thus can be expected to reduce VMT or they are small enough to have a negligible impact:

 Projects consisting of local serving retail (less than 50,000) ▫ Supermarket
▫ Restaurant/café/bar
▫ Coffee/donut shop
▫ Dry cleaners
▫ Barbershop
▫ Hair/nails salon
▫ Walk-in medical clinic
▫ Urgent care
▫ Auto repair/tire shop
▫ Gyms/health club
▫ Dance/yoga/fitness/material arts studio

 Projects consisting of land uses which by their nature are local-serving ▫ Local-serving K-12 schools
▫ Local parks
▫ Day care centers
▫ Local-serving gas stations
▫ Local-serving banks
▫ Local-serving hotels (e.g., non-destination hotels)
▫ Student housing projects on or adjacent to college campuses ▫ Local-serving assembly uses (places of worship, community organizations) ▫ Community institutions (public libraries, fires stations, local government) ▫ Local-serving community colleges that are consistent with the assumptions noted in the RTP/SCS ▫ Affordable or supportive housing
▫ Assisted living facilities
▫ Senior housing (as defined by HUD)

The project does not consist of any of the specified local land use services; therefore, the proposed project does not satisfy the City-established screening criteria for local essential service projects.

Projects with net daily trips less than 500 ADT

Based on a review of greenhouse emissions produced by several types of projects, the City determined that 500 trips would not to cause a less than significant impact under CEQA.:

 Projects generating with less than 5004 daily vehicle trips (ADT) ▫ Single family residential – 52 Dwelling Units or fewer ▫ Multi-family residential – 68 Dwelling Units or fewer ▫ General Office – 51,000 square feet of less
▫ Light Industrial – 100,000 square feet or less

4 This threshold was determined not to exceed 3.000MTCO2e per year as outlined in Appendix B of the City TIA Guidelines. 761

▫ Warehousing – 287,000 square feet or less
▫ High-Cube Fulfillment Center Warehouse – 357,000 square feet or less

The project consists of 71,985 square feet of warehouse which generates less than 500 daily trips. Therefore, this screening criteria is met, and the project may be presumed to result in a less than significant VMT impact.

ACTIVE TRANSPORTATION AND PUBLIC TRANSIT ANALYSIS

Existing Conditions

The project site is located on the north side of Hilton Drive approximately 950 feet east of Redwood Avenue.

The City of Fontana General Plan Community Mobility and Circulation Element approved and adopted July 23, 2023; shows Hilton Drive is classified as a Collector Street (2+ lanes on up to an 80-foot roadway section).

On-street parking is not restricted along the project frontage. There are no designated bike facilities currently on Hilton Drive; however, there is an existing Class I bike trail north of the site along the Pacific Electric Trail, and there are proposed Class II bike lanes on Foothill Avenue south of the project site and Cherry Avenue west of the project site. Sidewalks are not currently provided along the project frontage; however, there are existing sidewalks to the east and south of the project site. There are no designated transit routes on Hilton Drive; however, Route 66 runs along Foothill Boulevard south of the project site.

This analysis also assumes the project shall comply with the following conditions as part of the City of Fontana standard development review process to ensure adequate geometric design and emergency access:

 Site-adjacent roadways shall be constructed or repaired at their ultimate half-section width, including landscaping and parkway improvements in conjunction with development, or as otherwise required by the City of Fontana.

 All on-site and off-site roadway design, signing/striping, and traffic control improvements relating to the proposed project shall be submitted to the City for review and constructed following applicable State/Federal engineering standards to the satisfaction of the City of Fontana.

 The final grading, landscaping, and street improvement plans shall demonstrate that applicable sight distance requirements are met.

 The project shall comply with the City of Fontana municipal parking requirements which will be reviewed as a part of the standard development review process.

 Final project plans shall demonstrate adequate emergency vehicle access and circulation to the satisfaction of the City of Fontana Public Works and Fire Departments.

 A construction worksite traffic control plan shall comply with applicable engineering standards outlined in the California Manual of Uniform Traffic Control Devices and shall be submitted to the City for review and approval before the issuance of a grading permit or start of construction. The plan shall identify any roadway, sidewalk, bike route, or bus stop closures and detours as well as haul routes and hours of operation. All construction-related trips shall be restricted to off-peak hours to the extent possible.

The project does not propose any post-construction changes to off-site roadways; therefore, the project 762

would not conflict with adopted policies, plans, or programs regarding public transit, bicycle, or pedestrian facilities, or otherwise decrease the performance or safety of such facilities. Additionally, the proposed project would be consistent with the City’s Active Transportation Plan by providing a sidewalk along the project’s frontage for greater pedestrian connectivity.

CONCLUSION

The proposed project is forecast to generate approximately 150 daily PCE trips, including 13 PCE trips during the AM peak hour and 15 PCE trips during the PM peak hour.

The proposed project satisfies the City-established LOS screening criteria for projects generating fewer than 50 peak hour trips. Therefore, the proposed project does not warrant the preparation of a transportation impact study with LOS analysis based on the City-established LOS screening criteria.

The proposed project satisfies the City-established vehicle miles traveled (VMT) screening criteria for projects generating less than 500 daily trips. Therefore, preparation of a transportation impact study with VMT analysis is not warranted, and the project may be presumed to result in a less than significant VMT impact.

It has been a pleasure to assist you with this project. Should you have any questions or comments, please contact Perrie Ilercil at (714) 795-3100 ext. 103 or [email protected].

EXECUTIVE SUMMARY

The proposed project involves the development of two warehouse buildings with a total of 71,985 square feet. Vehicle access for the project site is proposed via two driveways onto Hilton Drive.

Project Construction Impacts

Project construction noise levels at nearby sensitive receptors were calculated using the FTA methodology and it was determined that project construction noise levels will not exceed the FTA 90 dBA L eq (8-hour). construction noise standard for impacts to residential land uses. This impact would be less than significant.

1. INTRODUCTION

This section describes the purpose of this study and the proposed project.

PURPOSE AND OBJECTIVES

The purpose of this report is to provide an assessment of the noise impacts resulting from construction of the proposed project and to identify mitigation measures that may be necessary to reduce those impacts. The noise issues related to the proposed land use and development have been evaluated in light of applicable federal, state and local policies, including those of the City of Fontana in the context of the California Environmental Quality Act (CEQA).

Although this is a technical report, effort has been made to write the report clearly and concisely. A list of acronyms and glossary are provided in Appendix A and Appendix B of this report to assist the reader with technical terms related to noise and vibration analysis.

PROJECT LOCATION

The 4.01-acre project site (APN: 1110-151-03) is located on the northside of Hilton Drive approximately 950 feet east of Redwood Avenue in the City of Fontana, California (See Figure 1). The project site is currently vacant and zoned industrial in the West End Specific Plan.

2. NOISE FUNDAMENTALS

Sound is a pressure wave created by a moving or vibrating source that travels through an elastic medium such as air. Noise is defined as unwanted or objectionable sound. The effects of noise on people can include general annoyance, interference with speech communication, sleep disturbance, and in extreme circumstances, hearing impairment.

Commonly used noise terms are presented in Appendix B. The unit of measurement used to describe a noise level is the decibel (dB). The human ear is not equally sensitive to all frequencies within the sound spectrum.

Therefore, the “A-weighted” noise scale, which weights the frequencies to which humans are sensitive, is used for measurements. Noise levels using A-weighted measurements are written dB(A) or dBA.

From the noise source to the receiver, noise changes both in level and frequency spectrum. The most obvious is the decrease in noise as the distance from the source increases. The manner in which noise reduces with distance depends on whether the source is a point or line source as well as ground absorption, atmospheric effects and refraction, and shielding by natural and manmade features. Sound from point sources, such as air conditioning condensers, radiates uniformly outward as it travels away from the source in a spherical pattern.

The noise drop-off rate associated with this geometric spreading is 6 dBA per each doubling of the distance (dBA/DD). Transportation noise sources such as roadways are typically analyzed as line sources, since at any given moment the receiver may be impacted by noise from multiple vehicles at various locations along the roadway. Because of the geometry of a line source, the noise drop-off rate associated with the geometric spreading of a line source is 3 dBA/DD.

Decibels are measured on a logarithmic scale, which quantifies sound intensity in a manner similar to the Richter scale used for earthquake magnitudes. Thus, a doubling of the energy of a noise source, such as a doubled traffic volume, would increase the noise levels by 3 dBA; halving of the energy would result in a 3 dBA decrease.

Figure 3 shows the relationship of various noise levels to commonly experienced noise events.

Average noise levels over a period of minutes or hours are usually expressed as dBA L eq, or the equivalent noise level for that period of time. For example, L eq(8-hr) would represent an 8-hour average. When no period is specified, a one-hour average is assumed.

Noise standards for transportation noise source/land use compatibility are stated in terms of the Community Noise Equivalent Level (CNEL) and the Day-Night Average Noise Level (DNL). CNEL is a 24-hour weighted average measure of community noise. CNEL is obtained by adding five decibels to sound levels in the evening (7:00 PM to 10:00 PM), and by adding ten decibels to sound levels at night (10:00 PM to 7:00 AM). This weighting accounts for the increased human sensitivity to noise during the evening and nighttime hours. DNL is a very similar 24-hour average measure that weights only the nighttime hours.

It is widely accepted that the average healthy ear can barely perceive changes of 3 dBA; that a change of 5 dBA is readily perceptible, and that an increase (decrease) of 10 dBA sounds twice (half) as loud. This definition is recommended by the California Department of Transportation’s Technical Noise Supplement to the Traffic Noise Analysis Protocol (2013).

CITY OF FONTANA MUNICIPAL CODE

Section 18-63 Scope, enumeration of prohibited noises.

a. This article shall apply to loud, excessive, impulsive, or intrusive interior and exterior sound or noise that annoys or disturbs persons of ordinary sensibilities emanating from any type of property or source within the city.

b. The following acts, which create loud, excessive, impulsive, or intrusive sound or noise that annoys or disturbs persons of ordinary sensibilities from a distance of 50 feet or more from the edge of the property, structure or unit in which the source is located, are declared to be in violation of this article, but such enumeration shall not be deemed to be exclusive, namely:

 Construction or repairing of buildings or structures. The erection (including excavating), demolition, alteration or repair of any building or structure other than between the hours of 7:00 AM and 6:00 PM on weekdays and between the hours of 8:00 a.m. and 5:00 p.m. 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, which permit may be granted for a period not to exceed three days or less while the emergency continues and which permit may be renewed for periods of three days or less while the emergency continues. If the building inspector should determine that the public health and safety will not be impaired by the erection, demolition, alteration or repair of any building or structure or the excavation of streets and highways within the hours of 6:00 PM and 7:00 AM, and if he shall further determine that loss or inconvenience would result to any party in interest, he may grant permission for such work to be done on weekdays within the hours of 6:00 PM and 7:00 AM, upon application being made at the time the permit for the work is awarded or during the progress of the work.

FEDERAL TRANSIT ADMINISTRATION

IN THE ABSENCE OF LOCAL QUANTITATIVE CONSTRUCTION NOISE THRESHOLDS , THE FEDERAL TRANSIT ADMINISTRATION (FTA) PROVIDES GUIDELINES (FTA 2018) THAT CAN BE CONSIDERED REASONABLE CRITERIA FOR CONSTRUCTION NOISE ASSESSMENT . FTA CONSTRUCTION NOISE STANDARDS ARE PROVIDED IN FEDERAL

INTERAGENCY COMMITTEE (FICON)

The Federal Interagency Committee on Noise (FICON) developed guidance (1992) to be used for the assessment of project-generated permanent increases in noise levels that consider the ambient noise level.

The FICON recommendations are based on studies that relate aircraft noise levels to the percentage of persons highly annoyed by aircraft noise. Although the FICON recommendations were specifically developed to assess aircraft noise impacts, these recommendations are often used in environmental noise impact assessments involving the use of cumulative noise exposure metrics, such as the average-daily noise level (CNEL) and equivalent continuous noise level (Leq). FICON standards as applied to increases due to construction noise would result in a significant impact if:
 Existing noise levels are below 60 dBA, and the project results in a 5 dBA or greater increase; or  Existing noise levels range between 60 and 65 dBA, a the project results in a 3 dBA or greater increase; or
 Existing noise levels exceed 65 dBA, and the project results in an increase of 1.5 dBA or greater..

4. ANALYTICAL METHODOLOGY AND MODEL PARAMETERS

This section discusses the analysis methodologies used to assess noise impacts.

CONSTRUCTION NOISE MODELING

Construction noise will vary depending on the construction process, type of equipment involved, location of the construction site with respect to sensitive receptors, the schedule proposed to carry out each task (e.g., hours and days of the week) and the duration of the construction work.

Construction noise associated with the proposed project was calculated at the sensitive receptor locations utilizing methodology presented in the Federal Transit Administration (FTA) Transit Noise and Vibration Impact Assessment Manual (2018) together with several key construction parameters, including: distance to each sensitive receiver, equipment usage, percent usage factor, and baseline parameters for the project site.

Distances to receptors were based on the acoustical center of the project site.

The equipment used to calculate the construction noise levels for each phase were based on the assumptions provided in the CalEEMod modeling. Sound emission levels associated with typical construction equipment as well as typical usage factors are provided in. Construction noise worksheets are provided in Appendix C.

VEHICLE NOISE MODELING

Noise associated with existing traffic volumes and existing plus project construction volumes was modeled using spreadsheets that use the FHWA Traffic Noise Prediction Model (FHWA-RD-77-108) formulas. The FHWA model arrives at the predicted noise level through a series of adjustments to the Reference Energy Mean Emission Level (REMEL). Key model parameters and REMEL adjustments are presented below:

 Roadway classification (e.g., freeway, major arterial, arterial, secondary, collector, etc.),  Roadway active width (distance between the center of the outer most travel lanes on each side of  the roadway),
 Average Daily Traffic (ADT) Volumes, Travel Speeds, Percentages of automobiles, medium trucks and  heavy trucks,
 Roadway grade and angle of view,
 Site conditions (e.g., soft vs. hard), and
 Percentage of total ADT which flows each hour throughout a 24-hour period.

Traffic noise levels were calculated at the right-of-way based on distance from the centerline of the analyzed roadway. The modeling is theoretical and does not take into account any existing barriers, structures, and/or topographical features that may further reduce noise levels. Therefore, the modeled noise levels are shown for comparative purposes only to show the difference between with and without project conditions. Traffic noise calculation worksheets are included in Appendix D.

5. CONSTRUCTION NOISE IMPACTS

CONSTRUCTION NOISE - ONSITE

The City of Fontana has set restrictions to control noise impacts associated with the construction of the proposed project. According to Section 18-63[b][7] of the city’s Municipal Code, Construction or repairing of buildings or structures, construction activity is limited: between the hours of 7:00 a.m. and 6:00 p.m. on weekdays and between the hours of 8:00 a.m. and 5:00 p.m. on Saturdays except in the case of urgent necessity. Project construction noise levels are, therefore, considered exempt from municipal regulation if activities occur within the hours specified in the City of Fontana Municipal Code, Section 18-63[7] of 7:00 a.m. to 6:00 p.m. on weekdays and between the hours of 8:00 a.m. to 5:00 p.m. on Saturdays. However, neither the General Plan nor the Municipal Code establish numeric maximum acceptable construction source noise levels at potentially affected receivers for CEQA analysis purposes. Therefore, a numerical construction threshold based on Federal Transit Administration (FTA) Transit Noise and Vibration Impact Assessment Manual is used for analysis of daytime construction impacts, as discussed below. According to the FTA, local noise ordinances are typically not very useful in evaluating construction noise. They usually relate to nuisance and hours of allowed activity, and sometimes specify limits in terms of maximum levels, but are generally not practical for assessing the impact of a construction project. Project construction noise criteria should account for the existing noise.

AS SHOWN IN FEDERAL INTERAGENCY COMMITTEE (FICON)

Table 1, the FTA considers a daytime exterior construction noise level of 80 dBA L eq(8-hour) for noise sensitive residential land uses, 85 dBA L eq(8-hour) for commercial uses, and 90 dBA L eq(8-hour) for industrial uses.

Construction noise would affect adjacent light industrial/warehouse land uses. Therefore, the proposed project would result in a significant impact if it:

 Results in noise levels that exceed 90 dBA Leq (8-hour) at the property line of an existing industrial land use.

Project construction noise levels at nearby sensitive receptors were calculated using the FTA methodology.

Construction noise modeling worksheets for each phase are provided in Appendix C. Modeled construction noise levels reach up to 70.7 dBA L eq at the property line shared with the industrial warehouse land use to the north, up to 68.5 dBA L eq at the property line shared with the industrial land use to the south, and up to

77.9 dBA L eq at the industrial properties located to the east and west. Project construction noise levels will not exceed the FTA 90 dBA L eq (8-hour) construction noise standard for impacts to residential land uses. This impact would be less than significant.

CONSTRUCTION NOISE - OFFSITE

As shown in Table 3, existing noise levels range between 62.9 and 65.6 dBA CNEL and existing plus project construction noise levels would range between 63.2 and 65.7 dBA CNEL. Project construction traffic would result in a less than 1 dB increase along both roadways and would not exceed the applicable FICON noise increase thresholds. Impacts would be less than significant and no mitigation measures are required.

Term Definition
Ambient Noise
Level
The all-encompassing noise environment associated with a given environment, at a specified time, usually a composite of sound from many sources, at many directions, near and far, in which usually no particular sound is dominant.

A-Weighted Sound
Level, dBA
The sound level obtained by use of A-weighting. The A-weighting filter de-emphasizes the very low and very high frequency components of the sound in a manner similar to the frequency response of the human ear.

CNEL
Community Noise Equivalent Level. CNEL is a weighted 24-hour noise level that is obtained by adding five decibels to sound levels in the evening (7:00 PM to 10:00 PM), and by adding ten decibels to sound levels at night (10:00 PM to 7:00 AM). This weighting accounts for the increased human sensitivity to noise during the evening and nighttime hours.

Decibel, dB
A logarithmic unit of noise level measurement that relates the energy of a noise source to that of a constant reference level; the number of decibels is 10 times the logarithm (to the base 10) of this ratio.

DNL, Ldn
Day Night Level. The DNL, or Ldn is a weighted 24-hour noise level that is obtained by adding ten decibels to sound levels at night (10:00 PM to 7:00 AM). This weighting accounts for the increased human sensitivity to noise during the nighttime hours.

Equivalent
Continuous Noise
Level, Leq
A level of steady state sound that in a stated time period, and a stated location, has the same A-weighted sound energy as the time-varying sound.

Fast/Slow Meter
Response
The fast and slow meter responses are different settings on a sound level meter. The fast response setting takes a measurement every 100 milliseconds, while a slow setting takes one every second.

Frequency, Hertz In a function periodic in time, the number of times that the quantity repeats itself in one second (i.e., the number of cycles per second).

L02, L08, L50, L90 The A-weighted noise levels that are equaled or exceeded by a fluctuating sound level, 2 percent, 8 percent, 50 percent, and 90 percent of a stated time period, respectively.

Lmax, Lmin
Lmax is the RMS (root mean squared) maximum level of a noise source or environment measured on a sound level meter, during a designated time interval, using fast meter response. Lmin is the minimum level.

Offensive/
Offending/Intrusive
Noise
The noise that intrudes over and above the existing ambient noise at a given location.

The relative intrusiveness of sound depends on its amplitude, duration, frequency, and time of occurrence, and tonal information content as well as the prevailing ambient noise level.

Root Mean Square
(RMS)
A measure of the magnitude of a varying noise source quantity. The name derives from the calculation of the square root of the mean of the squares of the values. It can be calculated from either a series of lone values or a continuous varying function.

6. Climate Risk Detailed Report

6.1. Climate Risk Summary
Cal-Adapt midcentury 2040–2059 average projections for four hazards are reported below for your project location. These are under Representation Concentration Pathway (RCP) 8.5 which assumes GHG emissions will continue to rise strongly through 2050 and then plateau around 2100.

Climate Hazard Result for Project Location Unit
Temperature and Extreme Heat 21.7 annual days of extreme heat Extreme Precipitation 5.25 annual days with precipitation above 20 mm Sea Level Rise — meters of inundation depth
Wildfire 0.00 annual hectares burned
Temperature and Extreme Heat data are for grid cell in which your project are located. The projection is based on the 98th historical percentile of daily maximum/minimum temperatures from observed historical data (32 climate model ensemble from Cal-Adapt, 2040–2059 average under RCP 8.5). Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi.

Extreme Precipitation data are for the grid cell in which your project are located. The threshold of 20 mm is equivalent to about ¾ an inch of rain, which would be light to moderate rainfall if received over a full day or heavy rain if received over a period of 2 to 4 hours. Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi.

Sea Level Rise data are for the grid cell in which your project are located. The projections are from Radke et al. (2017), as reported in Cal-Adapt (Radke et al., 2017, CEC-500-2017-008), and consider inundation location and depth for the San Francisco Bay, the Sacramento-San Joaquin River Delta and California coast resulting different increments of sea level rise coupled with extreme storm events. Users may select from four scenarios to view the range in potential inundation depth for the grid cell. The four scenarios are: No rise, 0.5 meter, 1.0 meter, 1.41 meters Wildfire data are for the grid cell in which your project are located. The projections are from UC Davis, as reported in Cal-Adapt (2040–2059 average under RCP 8.5), and consider historical data of climate, vegetation, population density, and large (> 400 ha) fire history. Users may select from four model simulations to view the range in potential wildfire probabilities for the grid cell. The four simulations make different assumptions about expected rainfall and temperature are: Warmer/drier (HadGEM2-ES), Cooler/wetter (CNRM-CM5), Average conditions (CanESM2), Range of different rainfall and temperature possibilities (MIROC5). Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi. 852

Discussion

The purpose of this study is to determine the hydrology impacts to the existing downstream facilities and properties and to ensure that the design mitigates increased flows to the existing facilities.

The study will verify flows to the downstream facilities and will also size infrastructure onsite to address stormwater quality design per the WQMP and show that the discharged flows to Hilton Drive are below the levels designed in the Master Plan Hydrology (“Master Hydrology for Fontana West End Venture Foothill Drains- Lines A, B, D, J, K”.)
The project proposes to develop a 3.94-acre site located at Hilton Drive, Lot 2 tract 13643. in the city of Fontana. The site is bounded to the north, east and west by commercial developments, and to the south by the right-of-way of Hilton Drive Site soils are Hydrologic Soil Group “A.” In its existing condition, the project site is undeveloped. The project site sheets storm water flows in a southerly direction, discharging into the right-of-way of Hilton Drive. It does not accept storm water run-on from the adjacent properties. See the Pre-Developed Hydrology Map in Appendix B. There is an existing storm drain constructed in Hilton Drive identified as Line K as shown on “Master Hydrology for Fontana West End Venture Foothill Drains- Lines A, B, D, J, K”. This parcel is part of areas 991.1 & 991.2 totaling 14.0 acres.

The project proposes to develop the site for commercial use. Proposed improvements consist of two warehouse buildings with loading docks, AC pavement, concrete hardscape, landscape, concrete curbs and gutters, two catch basin inlets, and a proposed underground infiltration system. The proposed development will be 87% impervious.

The proposed site design will mimic the existing drainage patterns of the property, directing storm flows to the southerly boundary of the project site. Drainage Area A1 consists of the easterly portion of the project site Storm water sheets across proposed AC pavement and landscape to be intercepted by proposed concrete gutters. The gutters convey flows southerly to be intercepted by a proposed inlet located at the southeasterly corner of the project site. The inlet discharges flows into a proposed storm drain that conveys flows westerly and discharges into the proposed underground infiltration system located beneath the southeasterly parking area. Drainage area A2 consists of the westerly portion of the project site. Storm water sheets across proposed AC pavement and landscape to be intercepted by proposed curb gutters. The gutters convey flows southerly to be intercepted by a proposed inlet located at the southwesterly corner of the project site and discharges into an underground infiltration system. See the Post-Developed Hydrology Map in Appendix C.

862

The proposed underground infiltration system has been designed to store the Design Capture Volume (DCV) for the project site, and to infiltrate it into the soil within 48 hours. The design is in accordance with the 2013 Technical Guidance Document for Water Quality Management Plans of San Bernardino County. See Appendix F for the design of the proposed underground infiltration system Rational Studies have been prepared for the pre-developed condition and post-developed condition using CivilCADD/CivilDESIGN software. The studies were prepared for the 2-year, 10-year, 25- year and 100-year storms. Per the County guidance for design of detention basins the pre-developed condition used 1-year rainfall rates for the 2-year storm, 5-year rainfall rates for the 10-year storm, 10- year rainfall rates for the 25-year storm and 25-year rainfall rates for the 100-year storm. Studies for the post-developed condition were prepared for the same storm intervals using 2-year, 10-year, 25-year and 100-year rainfall rates. This provides a conservative design for the sizing of the storage system per the County guidance. The pre-developed condition studies are shown in Appendix B; the post- developed condition studies are shown in Appendix C.

Unit hydrographs were prepared for the 3-hour and 24-hour dura tions for the 2-year storm, 10- year storm, 25-year storm and 100 year storm. These hydrographs were used to prepare routing calculations to show the underground infiltration system provides enough storage to ensure the overflow discharge at the southeast corner of the site does not exceed the allowable rate per the Master Plan Hydrology study. See Appendix D for result.

Appendix E includes the depth versus volume calculations for the storage and outflow rates of the underground infiltration system. The underground infiltration system consists of 8-foot diameter perforated CMP pipes, backfilled with washed rock (3/4” to 1-1/2” in diameter); said rock is wrapped with a non-woven filter fabric to prevent sediment from entering the voids of the pipe and to prevent erosion of the existing soil around the system. Details for this underground system are included in Appendix E. The storm flows start to fill the pipes and rock voids (assumed to be 40% of the overall volume). While the flows are filling the system, the flows will infiltrate into the soil at a rate of 0.41 cfs for the system. During larger storm events the system will fill and bubble out of the box inlets at the southeast corner of the site, flow through the proposed landscape plater and discharge into Cherry Avenue through a proposed underwalk drain. The routing calculations show the maximum post- developed discharge rate is below the flow that was tabled for this site per the Fontana West End Venture Master Plan Line K flows. See the table below showing the pre-developed flows, post- developed flows, allowable master plan flows and peak routed flows. Note that the time of concentration for the master plan flows is much higher than for the project site hydrology. This is a 863

conservative approach, since the project site pflows would be less using the higher time of concentration.

CONCLUSION
The underground infiltration system is designed to mitigate the increased runoff due to re- development of the site and also designed to meet the requirements per the County of San Bernardino WQMP Technical Guidance Document for treatment of the required storm volume. The WQMP Exhibit is included in Appendix F to show the design layout and cross-section of the underground infiltration system. It also shows the required volumes, as calculated in the WQMP for said project, and provided volumes. Capacity calculations for the systems are also included. The soils report including the infiltration rates are attached in Appendix F. The Factor of Safety Worksheet is included as well as drawdown calculations showing the system infiltrates within 48 hours. The drawdown time is 28.4 hours for the system which is well below the maximum 48 hour drawdown time. Routing calculations show the underground system allows for 0.41 cfs of infiltration. The 2- Year and 10-Year Storms will be contained within the underground infiltration system. The 25-Year and 100-Year storms will exceed the capacity of the underground infiltration system. Once the system is full and overflows the catch basin inlet at the southwest corner (lowest outlet) the flows will discharge through an underwalk drain to 864

Hilton Drive. The discharge rate for the 25-Year storm is 2.44 cfs and the discharge rate for the 100-Year 24-Hour storm is 11.25 cfs. These rates are well below the allowed rates per the master plan hydrology for Line K, 9.71 cfs and 12.46cfs, respectively.
