MIG, Inc – Fontana Citrus Industrial Building Project Noise and Vibration Report – July 2023
EXECUTIVE SUMMARY
This Noise Impact Analysis Report (“Report”) evaluates and documents noise levels associated with the construction and operation of the proposed Fontana Citrus Industrial Building Project (proposed “Project”) located at the northeast corner of the intersection of Citrus Avenue and Slover Avenue and at the southwest corner of the intersection of Oleander Avenue and Boyle Avenue, in the in the south-central part of the City of Fontana, in San Bernardino County.
This Report is intended to assist the California Environmental Quality Act (“CEQA”) Lead Agency (City of Fontana, “City”) with its review of the proposed Project’s potential noise and vibration impacts in compliance with the State CEQA Statutes and Guidelines, particularly in respect to the noise and vibration issues identified in Appendix G of the State CEQA Guidelines.
S.1 PROPOSED PROJECT DESCRIPTION
CHIPT Fontana Citrus Avenue, L.P. is proposing to develop the proposed Project, which would consist of consolidating 15 parcels into 1 parcel, demolishing 25 small existing structures, and constructing a new industrial building with approximately 360,500 square feet of gross building space (the “Building”). The building would be all-electric design. The approximately 16.12-acre rectangular Project site is bound by Boyle Avenue to the north, Slover Avenue and existing commercial development (an Arco fuel service station) to the south, existing non-conforming residential development to the east, and Citrus Avenue and existing commercial development (the same Arco fuel service station) to the west. The Project site is approximately 485 feet (0.9 miles) south of a Union Pacific Railroad (“UPRR”) line and 575 feet (0.11 miles) south of Interstate 10 (I-10).
The building would include 55 truck docks located mainly at the southern portion of the site, with additional docks located at the western portion of the site. Truck access would be provided along three driveways on the southern side of the site and one driveway in the northwestern corner of the site. Truck movements would generally occur along the southern side of the site and potentially from the northwestern truck dock to the southern docks via an internal driveway. Parking space for commuter vehicles (e.g., cars and pick-up trucks) would be present on the western and eastern perimeters of the proposed warehouse.
The proposed Project would involve construction and operational activities that would generate noise from construction equipment, on- and off-site vehicle and truck trips, truck dock loading and unloading activities (including cargo handling equipment use), and heating, ventilation, and air conditioning (“HVAC”) equipment. Construction activities are anticipated to last approximately 10 months and begin in early 2024. The building could operate 24-hours per day, 7 days per week.
S.2 POTENTIAL CONSTRUCTION NOISE AND VIBRATION IMPACTS
The proposed Project’s construction noise and vibration levels were estimated using the Federal Highway Administration’s Roadway Construction Noise Model (“RCNM”), Version 1.1. The RCNM is a computer program that uses empirical data and sound propagation principles to predict noise levels associated with a variety of construction equipment and operations. The equipment assumptions used in this Report are based on, and consistent with, the California Emissions Estimator Model (“CalEEMod”) construction phasing, equipment usage, and operating schedules used to evaluate the proposed Project’s potential construction air quality impacts (MIG, 2023).
Page S-II Executive Summary
MIG, Inc – Fontana Citrus Industrial Building Project Noise and Vibration Report – July 2023
The RCNM was used to model noise levels at 12 different receptor locations that could be impacted by the project’s construction noise levels. Construction noise was modeled to reflect both worst-case and typical construction noise levels. As estimated using the RCNM, the modeled worst-case construction noise level at any residential receptor location would be 94.4 dBA Leq. This would occur at the residence located east of the Project site, along Oleander Avenue, during the Project’s grading phase. During typical construction periods, construction noise levels would not exceed 80 dBA Leq at any residence near the Project site.
The City’s Municipal Code does not establish numeric standards for construction noise levels (e.g., 90 dBA Leq) but does limit construction activities to the hours of 7 AM to 6 PM during weekdays and 8 AM to 5 PM on Saturday (Municipal code Section 18-63). Potential construction noise level increases at residential land uses, when compared to the existing ambient noise environment, could be up to approximately 9 to 38 dBA higher than existing conditions, depending on the construction activities undertaken. This temporary increase is considered substantial and has the potential to annoy sensitive residential land uses. MIG, therefore, recommends Mitigation Measure NOI-1 be incorporated into the Project, which would reduce construction noise levels by 5 dBA to 10 dBA at individual receptor locations during the daytime. The implementation of Mitigation NOI-1 would lower overall Project construction noise levels, reduce the potential for Project construction noise levels to surprise or annoy residential receptors, and reduce the potential for Project construction noise levels to interfere with normal use of residential properties. The implementation of Mitigation Measure NOI-1 would, therefore, render the proposed Project’s potential construction noise levels less than significant with mitigation.
Vibrational construction activities could take place as close as approximately 30 feet from residential buildings and 35 feet from an adjacent commercial building. The use of a vibratory roller at these distances would have the potential to generate worst-case ground-borne vibration levels of approximately 0.172 inches per second peak particle velocity (in/sec PPV) and 0.145 in/sec PPV, respectively, which would be strongly perceptible per Caltrans’ criteria. At no point during construction would Project equipment generate ground-borne vibration that has the potential to damage the structural integrity of any buildings near the Project site. In addition, as vibration-generating equipment (e.g., vibratory roller) moves away from the property line, vibration levels would decrease. At approximately 375 feet, the vibratory roller would produce vibrations that would not be perceptible at nearby commercial or residential building locations. Although construction-related vibrations could be perceptible, they would not be excessive for several reasons. First, potential worst-case construction vibrations would be intermittent, lasting only a few hours each day at any individual receptor. Second, potential worst-case construction vibrations would occur only when equipment operates directly adjacent to a receptor, which is not anticipated to last more than several days in total. Third, all construction activity would occur during the daytime, when human beings are less sensitive to vibrations, and would not interfere with evening or nighttime use of residences. Finally, potential construction vibrations would not result in physical damage to any building or structure because estimated worst-case vibration levels would be below Caltrans’ guidelines for damage to sensitive residential structures and commercial structures. For these reasons, the proposed Project would not result in excessive ground-borne vibration levels. This impact would be less than significant.
S.3 POTENTIAL OPERATIONAL NOISE IMPACTS
Once constructed, the proposed Project would generate noise from on-site and off-site activities. On-site activities would include vehicle travel and parking, truck travel, maneuvering, and idling, heating, ventilation, and air conditioning (HVAC) equipment operations, and other miscellaneous activities such as refuse collection, small, non-diesel-powered pallet jacks and lifts, and landscaping equipment. Off-site
Executive Summary Page S- III
MIG, Inc – Fontana Citrus Industrial Building Project Noise and Vibration Report – July 2023
noise activities would include vehicle travel on Slover Avenue, Oleander Avenue, and Boyle Avenue used to access the site.
The proposed Project could generate worst-case combined hourly noise levels of approximately 55.2 dBA Leq at adjacent residential property lines. These noise levels would not exceed the City’s exterior noise standard for residential land uses (70 dBA Leq daytime / 65 dBA Leq nighttime), nor would the Project result in interior noise levels at any residential or commercial building that exceed City standards (45 dB for residential zoning districts). This impact would be less than significant.
The proposed Project would have a limited potential to generate operational noise levels that exceed City standards because the proposed Project’s design and estimated noise levels would be consistent with City’s General Plan Noise and Safety policies pertaining to noise. At worst-case, the proposed Project is estimated to generate hourly noise levels of 55.2 dBA. The proposed Project’s truck dock bays would be inset along the southern perimeter of the warehouse building, behind 10-foot-tall concrete screening walls. The warehouse building and concrete screening walls would visually screen and shield noise from the loading docks from impacting adjacent residential property lines.
The proposed Project would generate off-site vehicle trips that would be distributed onto Slover Avenue, Oleander Avenue, and Boyle Avenue and potentially increase noise levels along travel routes. Caltrans considers a doubling of total traffic volume to result in a three (3) dBA increase in traffic-related noise levels. The proposed Project would not double traffic volumes on any local roadway and, therefore, would not result in a substantial off-site increase in noise levels.
The proposed Project would not result in excessive operational vibration levels because it does not involve the use of large or vibration-inducing equipment near off-site structures during operations.
S.4 AIRPORT NOISE-RELATED IMPACTS
The proposed Project is located approximately 7.4 miles east of the nearest runway associated with the Ontario International Airport. The proposed Project is not located in a noise impact zone associated with Ontario International Airport. Therefore, the proposed Project would not expose people working in the Project area to excessive airport-related noise levels.
S.5 OTHER NOISE AND VIBRATION EFFECTS
The California Supreme Court in California Building Industry Association v. Bay Area Air Quality Management District, 62 Cal.4th 369 (2015) ruled that CEQA review is focused on a project’s impact on the environment “and not the environment’s impact on the project.” Per this ruling, a Lead Agency is not required to analyze how existing conditions might impact a project’s future users or residents; however, a Lead Agency may elect to disclose information relevant to a project even if it not is considered an impact under CEQA. Furthermore, the City’s General Plan Noise Element set noise standards for receiving land uses which require evaluation for consistency and compliance even if such evaluation is not required by CEQA.
The City’s General Plan Noise and Safety does not establish noise and land use compatibility standards for industrial land uses because such land uses are not considered to be noise-sensitive uses. As described in Section 4.2.1, the 24-hour CNEL value at LT-1 was determined to be 67.7 dBA CNEL (see Table 4 1). This CNEL value is within the normally acceptable noise level (75 CNEL) identified for industrial land uses in the Governor’s Office of Planning and Research (OPR) most recently published General Plan
Page S-IV Executive Summary
MIG, Inc – Fontana Citrus Industrial Building Project Noise and Vibration Report – July 2023
Guidelines (OPR, 2017). The proposed Project, therefore, would not be exposed to unacceptable exterior noise levels that exceed City General Plan noise and land use compatibility standards.
The proposed building’s southern façade would be subjected to noise levels of approximately 70.4 dBA CNEL. Standard construction techniques and materials for new commercial/industrial buildings are commonly accepted to provide a minimum exterior to interior noise attenuation (i.e., reduction) of 30 to 32 dBA with all windows and doors closed, which would result in interior noise levels of approximately 41 dBA Leq for occupied rooms fronting Slover Avenue. Thus, with standard construction techniques, the proposed Project would satisfy interior building code noise requirements.
S.6 RECOMMENDED MITIGATION MEASURES
To reduce the potential for Project construction activities to result in a substantial temporary increase in ambient noise levels in the vicinity of the Project site that could annoy adjacent residential receptors and/or interfere with the normal use and enjoyment of residential properties, MIG recommends Mitigation Measure NOI-1 be incorporated into the Project.
Mitigation Measure NOI-1: Reduce Construction Noise Levels. To reduce potential noise levels associated with construction of the proposed Project, the Applicant and/or its designated contractor, contractor’s representatives, or other appropriate personnel shall:
1) Notify Adjacent Land Use of Planned Construction Activities. This notice shall be provided at
least two weeks prior to the start of any construction activities, describe the noise control
measures to be implemented by the Project, and include the name and phone number of a designated contact for the Applicant and the City of Fontana responsible for handling
construction-related noise complaints (per action #5 below). This notice shall be provided to
the owner/occupants of all occupied properties within 250 feet of the Project site.
2) Restrict work hours/equipment noise. All construction-related work activities, including material deliveries, shall be subject to the requirements of City Municipal Code Section 18-63.
Construction activities, including deliveries, shall only occur during the hours of 7:00 AM to
6:00 PM on weekdays and 8:00 AM to 5:00 PM on Saturdays. The Applicant and/or its contractor shall post a sign at all entrances to the construction site informing contractors,
subcontractors, construction workers, etc. of this requirement.
3) Construction equipment selection, use, and noise control measures. The following measures shall apply during construction activities:
a) Contractors shall use the smallest size equipment capable of safely completing work
activities. b) Construction staging shall occur as far away from the adjacent residential properties as
possible.
c) The Applicant and/or his contractor shall connect to existing electrical service at the site to avoid the use of stationary power generators. This measure shall be subject to the
approval of the local electric utility. If electric service is denied, the Applicant shall ensure
actions 3a, 3b, and 3d are implemented.
d) All stationary noise-generating equipment such as pumps, compressors, and welding machines shall be shielded and located as far from residential land uses as possible given
site and active work constraints. Shielding may consist of a three- or four-sided enclosure
Executive Summary Page S- V
MIG, Inc – Fontana Citrus Industrial Building Project Noise and Vibration Report – July 2023
provided the structure/enclosure breaks the line of sight between the equipment and the receptor and provided for proper ventilation and equipment operation.
e) Heavy equipment engines shall be equipped with standard noise suppression devices such as mufflers, engine covers, and engine/mechanical isolators, mounts, and be maintained in accordance with manufacturer’s recommendations during active construction activities.
f) Pneumatic tools shall include a noise suppression device on the compressed air exhaust.
g) No radios or other amplified sound devices shall be audible beyond the property line of the construction site.
4) Install Construction Noise Barrier. During all demolition, site preparation, grading, trenching, and structure foundation work (e.g., excavation, pad pour, etc.), the Applicant shall install and maintain a physical noise barrier along the eastern perimeter of the site. The noise barrier shall extend to a height of eight (8) feet above grade. Potential barrier options capable of reducing construction noise levels could include, but are not limited to:
a) A plywood or other barrier installed at-grade (or mounted to structures located at-grade, such as a K-Rail), and consisting of a solid material (i.e., free of openings or gaps other than weep holes) that has a minimum rated transmission loss value of 20 dB.
b) Commercially available acoustic panels or other products such as acoustic barrier blankets that have a minimum sound transmission class (STC) or transmission loss value of 20 dB.
c) Any combination of noise barriers and commercial products that have a minimum sound transmission class (STC) or transmission loss value of 20 dB.
The noise barrier may be removed following the completion of building foundation work (i.e., it is not necessary once framing and typical vertical building construction begins provided no other grading, foundation, etc. work is still occurring on-site). Furthermore, the noise barrier shall not be required if the 10-foot-tall perimeter concrete masonry unit wall included in the project’s site plan is fully constructed prior to the start of substantial demolition, site preparation, and grading activities at the site (i.e., only clearing and grubbing and grading necessary to access the site and install the perimeter wall may occur).
5) Prepare a Construction Noise Complaint Plan: The Applicant shall prepare a Construction Noise Complaint Plan that shall:
a) Identify the name and/or title and contact information (including phone number and email) for a designated Project and City representative responsible for addressing construction-related noise issues.
b) Includes procedures describing how the designated Project representative will receive, respond, and resolve construction noise complaints.
c) At a minimum, upon receipt of a noise complaint, the Project representative shall notify the City contact, identify the noise source generating the complaint, determine the cause of the complaint, and take steps to resolve the complaint.

2 PROPOSED PROJECT DESCRIPTION
The following describes the Building and the activities proposed by the Project.
2.1 PROJECT LOCATION
The proposed Project would be located at the northeast corner of the intersection of Citrus Avenue and Slover Avenue and at the southwest corner of the intersection of Oleander Avenue and Boyle Avenue in the south-central part of the City of Fontana, San Bernardino County. The Project site is a partially developed, approximately 16.12-acre (gross), irregularly shaped area that consists of 15 parcels of land (Assessor’s Parcel Number (APN) 0251-151-03, 07, -09, -10, -14, -15, -16, -21, -22 and -39 to -44) The site is bound by Boyle Avenue to the north, Slover Avenue and existing commercial development (an Arco fuel service station) to the south, existing non-conforming residential development to the east, and Citrus Avenue and existing commercial development (the same Arco fuel service station) to the west (see Figure 2-1: Aerial View of Project Site).
The Project site is, at closest, approximately 485 feet (0.09 miles) south of a Union Pacific Railroad (UPRR) line and 575 feet (0.1 miles) south of Interstate 10 (I-10).1
2.1.1 SITE LAND USE AND ZONING
The City’s General Plan primarily designates the site as Light Industrial (I-L); however, a single parcel in the southern portion of the site (APN 251-151-10) is designated Community Commercial (C-C; (City of Fontana, 2022a). The City’s Zoning Map also designates the Project site as Light Industrial (M-1) and Community Commercial (C-1; City of Fontana, 2022b). Per the Zoning Map, the Project site is not located within any Specific Plan area or zoning overlay district.
2.1.2 SURROUNDING LAND USES
The proposed Project site is surrounded by a mix of non-conforming residential and light industrial uses to the north (across Boyle Avenue), non-conforming residential uses to the east and commercial uses to the southeast (across Oleander Avenue), commercial, light industrial, educational, and residential land uses to the south (across Slover Avenue), and commercial and residential land uses to the west (primarily across Citrus Avenue).
The proposed Project is located approximately 7.4 miles east of the nearest runway associated with the Ontario International Airport. Based on the City’s General Plan, Fontana has no areas identified as having a residential land use designation within the noise impact zones (City of Fontana, 2018; Ontario International Airport – Inter Agency Collaborative, 2011). Airport-related noise is not considered in this Report due to the proximity to the nearest airport.
1 Unless otherwise indicated, reported distances are measured between the edge of the listed feature (e.g., road or rail right-of-way, land use property boundary, etc.) and the Project’s closest property line.

Proposed Project Description Page 2-3
MIG, Inc – Fontana Citrus Industrial Building Project Noise and Vibration Report – July 2023
2.2 EXISTING SITE DESCRIPTION AND OPERATIONS
The Project site includes occupied and vacated residences, ancillary residential structures (e.g., garages, sheds, and other structures), and a retail building. The site includes 13 single-family residences and 12 ancillary structures occupying approximately 31,359 feet, a metal building occupying 19,445 square feet, and a plant nursery occupying approximately 950 square feet. A majority of the site is undeveloped and consists of crushed aggregate/ruderal vegetation.
2.3 PROPOSED SITE DEVELOPMENT AND OPERATIONS
The proposed Project would involve the development of a new, all-electric approximately 360,500 square foot industrial building. Approximately 5,500 square feet of the building’s total area would consist of office space. The entire approximately 16.12-acre site would be graded; the portions of the site not developed with the Building would either be hardscaped (e.g., parking or sidewalks) or landscaped. The proposed Project site plan is shown in Figure 2-2: Site Plan.
2.3.1 SITE LAYOUT AND BUILDING DESCRIPTION
The proposed rectangular building would reach a height of 50 feet above ground level. The long axis of the building, like the site, would be oriented east to west, with the front of the building on the eastern perimeter. The building’s office space would be located at the southeastern corner of the building. Employee parking areas would generally be located along the site’s western and eastern perimeter.
The Building would include 55 truck docks located mainly at the southern portion of the site, with additional docks located at the western portion of the site. The building’s southern façade would include 46 truck docks that would be set back from the site’s southern property line by approximately 206 feet and the building’s western façade would include 9 truck docks that would be set back from the northwestern property boundary by at least 185 feet. The building’s facades would be set back at least 20 feet from the site’s northern property line, 146 feet from the site’s southern property line, 58 feet from the eastern property line, and 50 feet from the western property line. Consistent with Fontana Industrial Sustainability Ordinance requirements (see Section 4.3.4.1), the Project would include a 10-foot-tall concrete screening wall around the site perimeter. An existing 6-foot-tall concrete wall located along a portion of the shared property line with the Arco fuel station adjacent to the southwest corner of the site would also remain in place.
2.3.2 SITE ACCESS AND PARKING
Access to the site would be provided via five driveways: two along the northern portion of the site on Boyle Avenue and three along the southern portion of the site on Slover Avenue. There would be drive aisles along the western, southern, and eastern portions of the site which would connect these five driveways. The southwest, southcentral, and southeast driveways would be connected by a 56-foot-wide drive aisle while the drive aisles along the western and eastern portions of the site would be as narrow as 30 feet wide. The three southern driveways would provide access to the 46 docks along the building’s southern façade. The northwestern driveway would provide access to the 9 docks along the building’s western façade and the northeastern driveway would provide access to employee parking in the eastern portion of the site. There would be a total of 110 employee parking spaces, which would be located along the western portion of the site (30 stalls) and the eastern portion of the site (81 stalls). In addition, there would be 52 trailer stalls located along the southern boundary of the site. A median in Slover Avenue would prevent trucks from turning left into the site’s southern driveways.

2.3.3 PROJECT OPERATIONS
The proposed Project is considered a speculative industrial building because tenants/end users have not been identified. In general, industrial warehouse buildings generate noise emissions from sources such as on- and off-site vehicle trips, on-site truck maneuvering, loading, and unloading activities, on-site parking, and other on-site operations. With regards to potential Project operations that could generate emission, this Report assumes:
• Hours of Operation: The Project could operate up to 24 hours per day, 7 days per week. Employee shift changes would occur in the morning (approximately 7 to 8 AM), afternoon (approximately 3 PM to 4 PM), and nighttime (approximately 11 PM to 12 AM), with most employees working a daytime shift.
• Vehicle Trip Generation: The proposed Project’s trip generation potential, as estimated in the Site Access Memorandum prepared for the Project, is summarized in Table 2-1 (Ganddini Group, 2023). As shown in Table 2-1, the proposed Project would result in 505 total vehicle trips per day, including 425 passenger vehicle trips and 80 truck trips. The site memorandum assumed that 95% of inbound trucks would access and exit the site from the southern driveways on Slover Avenue and 5% would access and exit the site from the northwestern driveway on Boyle Avenue.
• Yard Equipment: The Project could include the use and operation of up to 43 electric -powered forklifts, pallet jacks, and other material handling equipment and 1 electric-powered yard hostler. This estimate is based on the average equipment usage at high cube warehouses, based on a survey conducted by the South Coast Air Quality Management District (SCAQMD, 2014). This forklifts would primarily operate inside the proposed industrial warehouse building.

2.3.4 PROJECT DESIGN FEATURES THAT REDUCE NOISE POLLUTION
The proposed Project would include design features that reduce exposure to noise generation associated with the Project, and that are necessary to comply with the City of Fontana Municipal Code, Chapter 9, Article V: Industrial Commerce Centers Sustainability Standards. These design features are part of the proposed Project and are reflected in the analyses contained in this Report; they are not mitigation measures. The proposed Project’s emission reduction design features are summarized in Table 2-2.
Table 2-2: Summary of Project Design Features that Reduce Noise Pollution
Project Design Feature Code Section and Requirement Design Feature Description Project Design Feature
Landscaping Buffer 9-71.(a) Warehouse buildings larger than 50,000 sq ft but less than 400,000 sq ft shall include a minimum 10-foot-wide landscaping buffer, measured from the property line of all adjacent sensitive receptors. Buffer areas shall include at a minimum a solid decorative wall of at least 10 feet in height, natural ground landscaping, and solid screen buffering trees, unless there is an existing solid block wall.
The Applicant will require a 10-foot- wide landscaping buffer, measured from the property line adjacent sensitive receptors to the east. The buffer includes a minimum10-foot solid wall, natural ground landscaping, and a solid screen of evergreen, drought tolerant buffer trees.
This buffer would limit noise transmission to surrounding adjacent land uses and receptors.
Location of Truck Docks 9-71.(f) Unless impossible, docks and truck entries shall be oriented away from abutting sensitive receptors. As best able, docks, truck entries and drive aisles shall be located away from nearby sensitive receptors.
The Project is designed with docks located to the south and west, away from sensitive receptors to the north and east. The northwest driveway near residential receptors to the north of the Project site across Boyle Avenue would only be used by 5% of truck trips (Ganddini 2023).
The site plan and layout of the drive aisle and docks would minimize noise due to both docks areas facing away from nearby sensitive receptors and being recessed on the western and southern sides of the site, respectively. The trailer stalls area and setbacks of the building from the eastern and southern property lines would also limit noise
Proposed Project Description Page 2-7

transmission originating from the docks.
Truck Routing and Idling Restriction 9-72.(c, e-i, d) Signs are required for a 3-minute idling limit, on-site circulation patterns, parking, truck routes, and the SCAQMD contact information.
A truck routing plan to and from the state highway system based on the City's latest truck route map is required. It will include the facility’s operational characteristics and measures for preventing truck queuing, circling, stopping, and parking on public streets.
Facility operators will submit a truck routing plan and install the required signs.
On-site circulation, parking, and signs would help reduce traffic congestion entering into and exiting from the site via Boyle Avenue and Slover Avenue. These features would also reduce truck idling, and therefore would reduce noise generation.
Use of Zero Emission On-site Operations Equipment (forklifts, pallet jacks, etc.)
9-73.(a) On-site motorized operational equipment shall be ZE (zero emission).
The Applicant will require the use of electric forklifts, pallet jacks, and other cargo/material handling equipment as a lease condition / condition of sale.
Electric motorized operational equipment would generally limit noise generation, especially in and around the docks area.
2.4 PROJECT CONSTRUCTION
Construction of the proposed Project is anticipated to begin as early as January 2024 and take approximately 10 months to complete. The development of the approximately 16.12-acre site and the construction of the approximately 360,500 square feet industrial warehouse building would require demolition, site preparation, grading, trenching, building construction, paving, and architectural coating phases/activities. A total of 51,754 square-feet of building space would be demolished. Site grading would require approximately 18,600 cubic yards of cut and 24,000 cubic yards of fill, resulting in the net import of 5,400 cubic yards of soil. The proposed Project is anticipated to require varying types of equipment throughout the different construction phases including, but not limited to, bulldozers, backhoes, loaders, graders, cranes and forklifts. Table 2-3 summarizes the proposed Project’s construction phasing and the typical pieces of heavy-duty, off-road construction equipment that would be required during each phase.

3 NOISE AND VIBRATION FUNDAMENTALS
3.1 DEFINING NOISE
“Sound” is a vibratory disturbance created by a moving or vibrating source and is capable of being detected. For example, airborne sound is the rapid fluctuation of air pressure above and below atmospheric pressure. “Noise” may be defined as unwanted sound that is typically construed as loud, unpleasant, unexpected, or undesired by a specific person or for a specific area.
3.1.1 SOUND PRODUCTION
Sound has three properties: frequency (or pitch), amplitude (or intensity or loudness), and duration. Pitch is the height or depth of a tone or sound and depends on the frequency of the vibrations by which it is produced. Sound frequency is expressed in terms of cycles per second, or Hertz (Hz). Humans generally hear sounds with frequencies between 20 and 20,000 Hz and perceive higher frequency sounds, or high pitch noise, as louder than low-frequency sound or sounds low in pitch. Sound intensity or loudness is a function of the amplitude of the pressure wave generated by a noise source combined with the reception characteristics of the human ear. Atmospheric factors and obstructions between the noise source and receptor also affect the loudness perceived by the receptor.
The frequency, amplitude, and duration of a sound all contribute to the effect on a listener, or receptor, and whether or not the receptor perceives the sound as “noisy” or annoying. Despite the ability to measure sound, human perceptibility is subjective, and the physical response to sound complicates the analysis of its impact on people. People judge the relative magnitude of sound sensation in subjective terms such as “noisiness” or “loudness.”
3.1.2 MEASURING SOUND
Sound pressure levels are typically expressed on a logarithmic scale in terms of decibels (dB). A dB is a unit of measurement that indicates the relative amplitude (i.e., intensity or loudness) of a sound, with 0 dB corresponding roughly to the threshold of hearing for the healthy, unimpaired human ear. Since decibels are logarithmic units, an increase of 10 dBs represents a ten-fold increase in acoustic energy, while 20 dBs is 100 times more intense, 30 dBs is 1,000 times more intense, etc. In general, there is a relationship between the subjective noisiness or loudness of a sound and its intensity, with each 10 dB increase in sound level perceived as approximately a doubling of loudness. Due to the logarithmic basis, decibels cannot be directly added or subtracted together using common arithmetic operations: 50 𝑑𝑑𝑑𝑑𝑑𝑑𝑑𝑑𝑑𝑑𝑑𝑑𝑑𝑑𝑑𝑑+50 𝑑𝑑𝑑𝑑𝑑𝑑𝑑𝑑𝑑𝑑𝑑𝑑𝑑𝑑𝑑𝑑 ≠100 𝑑𝑑𝑑𝑑𝑑𝑑𝑑𝑑𝑑𝑑𝑑𝑑𝑑𝑑𝑑𝑑
Instead, the combined sound level from two or more sources must be combined logarithmically. For example, if one noise source produces a sound power level of 50 dBA, two of the same sources would combine to produce 53 dB as shown below. 10 ∗ 10 𝑑𝑑𝑙𝑙𝑙𝑙�10�5010�+ 10�5010��=53 𝑑𝑑𝑑𝑑𝑑𝑑𝑑𝑑𝑑𝑑𝑑𝑑𝑑𝑑𝑑𝑑
In general, when one source is 10 dB higher than another source, the quieter source does not add to the sound levels produced by the louder source because the louder source contains ten times more sound energy than the quieter source.
Page 3-2 Noise Fundamentals
MIG, Inc – Fontana Citrus Industrial Building Project Noise and Vibration Report – July 2023
3.1.3 CHARACTERIZING SOUND
Although humans generally can hear sounds with frequencies between 20 and 20,000 Hz most of the sound humans are normally exposed to do not consist of a single frequency, but rather a broad range of frequencies perceived differently by the human ear. In general, humans are most sensitive to the frequency range of 1,000–8,000 Hz and perceive sounds within that range better than sounds of the same amplitude in higher or lower frequencies. Instruments used to measure sound, therefore, include an electrical filter that enables the instrument’s detectors to replicate human hearing. This filter known as the “A-weighting” or “A-weighted sound level” filters low and very high frequencies, giving greater weight to the frequencies of sound to which the human ear is typically most sensitive. Most environmental measurements are reported in dBA, meaning decibels on the A-scale. Most environmental measurements are reported in dBA, meaning decibels on the A-scale. A list of common noise sources and their associated A-weighted noise level is provided in Table 3-1. Other weightings include the B-, C-, and D-weighting, but these scales are not commonly used for environmental noise because human annoyance correlates well with the A-weighting and these weighting scales are not incorporated in typical environmental noise descriptors.
Sound levels are usually not steady and vary over time. Therefore, a method for describing either the average character of the sound or the statistical behavior of the variations over a period of time is necessary. The continuous equivalent noise level (Leq) descriptor is used to represent the average character of the sound over a period of time. The Leq represents the level of steady-state noise that would have the same acoustical energy as the sum of the time-varying noise measured over a given time period. Leq is useful for evaluating shorter time periods over the course of a day. The most common Leq averaging period is hourly, but Leq can describe any series of noise events over a given time period.
Variable noise levels are the values that are exceeded for a portion of the measured time period. Thus, the L01, L05, L25, L50, and L90 descriptors represent the sound levels exceeded 1%, 5%, 25%, 50%, and 90% of the time the measurement was performed. The L90 value usually corresponds to the background sound level at the measurement location.
When considering environmental noise, it is important to account for the different responses people have to daytime and nighttime noise. In general, during the nighttime, background noise levels are generally quieter than during the daytime but also more noticeable because household noise decreases as people begin to retire and sleep. Accordingly, a variety of methods for measuring noise have been developed. The California General Plan Guidelines for Noise Elements identifies the following common metrics for measuring noise (OPR, 2017):
• Ldn or DNL (Day-Night Average Level): The average equivalent A-weighted sound level during a 24-hour day, divided into a 15-hour daytime period (7:00 AM to 10:00 PM) and a 9-hour nighttime period (10:00 PM to 7:00 AM). A 10 dB “penalty” is added to measure nighttime noise levels when calculating the 24-hour average noise level. For example, a 45-dBA nighttime sound level (e.g., at 2:00 AM) would contribute as much to the overall day-night average as a 55-dBA daytime sound level (e.g., at 7:00 AM).
• CNEL (Community Noise Equivalent Level): The CNEL descriptor is similar to DNL, except that it includes an additional 5 dBA penalty for noise events that occur during the evening time period (7:00 PM to 10:00 PM). For example, a 45-dBA evening sound level (e.g., at 8:00 PM) would contribute as much to the overall day-night average as a 50-dBA daytime sound level (e.g. at 8:00 AM).

The artificial penalties imposed during DNL and CNEL calculations are intended to account for a receptor’s increased sensitivity to noise levels during quieter nighttime periods. As such, the DNL and CNEL metrics are usually applied when describing longer-term ambient noise levels because they account for all noise sources over an extended period of time and account for the heightened sensitivity of people to noise during the night. In contrast, the Leq metric is usually applied to shorter reference periods where sensitivity is presumed to remain generally the same.
Federal and State agencies have established noise and land use compatibility guidelines that use averaging approaches to noise measurement. The State Department of Aeronautics and the California Commission on Housing and Community Development have adopted the CNEL for evaluating community noise exposure levels.

3.1.4 SOUND PROPAGATION
The energy contained in a sound pressure wave dissipates and is absorbed by the surrounding environment as the sound wave spreads out and travels away from the noise generating source. The strength of the source is often characterized by its “sound power level.” Sound power level is independent of the distance a receiver is from the source and is a property of the source alone. Knowing the sound power level of an idealized source and its distance from a receiver, sound pressure level at the receiver point can be calculated based on geometrical spreading and attenuation (noise reduction) as a result of distance and environmental factors, such as ground cover (asphalt vs. grass or trees), atmospheric absorption, and shielding by terrain or barriers.
For an ideal “point” source of sound, such as mechanical equipment, the energy contained in a sound pressure wave dissipates and is absorbed by the surrounding environment as the sound wave spreads out in a spherical pattern and travels away from the point source. Theoretically, the sound level attenuates, or decreases, by 6 dB with each doubling of distance from the point source. In contrast, a “line” source of sound, such as roadway traffic or a rail line, spreads out in a cylindrical pattern and theoretically attenuates by 3 dB with each doubling of distance from the line source; however, the sound level at a receptor location can be modified further by additional factors. The first is the presence of a reflecting plane such as the ground. For hard ground, a reflecting plane typically increases A-weighted sound pressure levels by 3 dB. If some of the reflected sound is absorbed by the surface, this increase will be less than 3 dB. Other factors affecting the predicted sound pressure level are often lumped together into a term called “excess attenuation.” Excess attenuation is the amount of additional attenuation that occurs beyond simple spherical or cylindrical spreading. For sound propagation outdoors, there is almost always excess attenuation, producing lower levels than what would be predicted by spherical or cylindrical spreading. Some examples include attenuation by sound absorption in air; attenuation by barriers; attenuation by rain, sleet, snow, or fog; attenuation by grass, shrubbery, and trees; and attenuation from shadow zones created by wind and temperature gradients. Under certain meteorological conditions, like fog and low-level clouds, some of these excess attenuation mechanisms are reduced or eliminated due to noise reflection.
3.1.5 NOISE EFFECTS ON HUMANS
Noise effects on human beings are generally categorized as:
• Subjective effects of annoyance, nuisance, and/or dissatisfaction
• Interference with activities such as speech, sleep, learning, or relaxing
• Physiological effects such as startling and hearing loss
Most environmental noise levels produce subjective or interference effects; physiological effects are usually limited to high noise environments such as industrial manufacturing facilities or airports.
Predicting the subjective and interference effects of noise is difficult due to the wide variation in individual thresholds of annoyance and past experiences with noise; however, an accepted method to determine a person’s subjective reaction to a new noise source is to compare it the existing environment without the noise source, or the “ambient” noise environment. In general, the more a new noise source exceeds the ambient noise level, the more likely it is to be considered annoying and to disturb normal activities.
Under controlled conditions in an acoustical laboratory, the trained, healthy human ear is able to discern 1‐dB changes in sound levels when exposed to steady, single‐frequency (“pure‐tone”) signals in the mid‐frequency (1,000–8,000 Hz) range. In typical noisy environments, changes in noise of 1 to 2 dB are
Noise Fundamentals Page 3-5
MIG, Inc – Fontana Citrus Industrial Building Project Noise and Vibration Report – July 2023
generally not perceptible. However, it is widely accepted that people can begin to detect sound level increases of 3 dB in typical noisy environments. Further, a 5-dB increase is generally perceived as a distinctly noticeable increase, and a 10-dB increase is generally perceived as a doubling of loudness that would almost certainly cause an adverse response from community noise receptors.
When exposed to high noise levels, humans may suffer hearing damage. Sustained exposure to high noise levels (e.g., 90 dB for hours at a time) can cause gradual hearing loss, which is usually temporary, whereas sudden exposure to a very high noise level (e.g., 130 to 140 dB) can cause sudden and permanent hearing loss. In addition to hearing loss, noise can cause stress in humans and may contribute to stress-related diseases, such as hypertension, anxiety, and heart disease (Caltrans, 2013).
3.1.6 GROUND-BORNE VIBRATION AND NOISE
Vibration is the movement of particles within a medium or object such as the ground or a building. Vibration may be caused by natural phenomena (e.g., earthquakes, volcanic eruptions, sea waves, landslides) or humans (e.g., explosions, machinery, traffic, trains, construction equipment). Vibration sources are usually characterized as continuous, such as factory machinery, or transient, such as explosions.
As is the case with airborne sound, ground-borne vibrations may be described by amplitude and frequency; however, unlike airborne sound, there is no standard way of measuring and reporting amplitude. Vibration amplitudes can be expressed in terms of velocity (inches per second) or discussed in dB units to compress the range of numbers required to describe vibration. Vibration impacts to buildings are usually discussed in terms of peak particle velocity (PPV) in inches per second (in/sec). PPV represents the maximum instantaneous positive or negative peak of a vibration signal and is most appropriate for evaluating the potential for building damage. Vibration can impact people, structures, and sensitive equipment. The primary concern related to vibration and people is the potential to annoy those working and residing in the area. Vibration with high enough amplitudes can damage structures (such as crack plaster or destroy windows). Ground-borne vibration can also disrupt the use of sensitive medical and scientific instruments, such as electron microscopes. Potential human annoyance associated with ground-borne velocity is typically assessed using velocity decibel (VdB) notation.
Ground-borne noise is noise generated by vibrating building surfaces such as floors, walls, and ceilings that radiate noise inside buildings subjected to an external source of vibration. The vibration level, the acoustic radiation of the vibrating element, and the acoustical absorption of the room are all factors that affect potential ground-borne noise generation.

4 ENVIRONMENTAL AND REGULATORY SETTING
This chapter provides information on the environmental and regulatory noise setting of the proposed Project.
4.1 PROJECT LOCATION AND SITE DESCRIPTION
The proposed Project would be located on developed light industrial land in the southern part of the City of Fontana. Refer to Section 2.1.2 for a description of the Project site and its surroundings.
4.2 EXISTING NOISE ENVIRONMENT
The City’s General Plan Chapter 11 Noise and Safety identifies traffic noise, including traffic on major roadways (e.g., Interstate 10 (I-10) and Interstate 15 (I-15) freeways, portions of SR-210, etc.), airport noise associated with Ontario International Airport, and non-transportation sources including industrial, commercial, and residential activities and equipment as the predominant noise sources in the City (City of Fontana, 2018). The proposed Project is located along Citrus Avenue and Slover Avenue, south of I-10 freeway. The segment of Citrus Avenue north of Jurupa Avenue and Slover Avenue are designated as truck routes by the City (City of Fontana, 2018). The closest air travel facility to the Project site is Ontario International Airport, located approximately 7.4 miles to the west.
4.2.1 AMBIENT NOISE LEVELS AT PROJECT SITE
MIG conducted ambient noise level monitoring at and near the proposed Project site from approximately 11:00 AM on Wednesday, February 5, 2023, to 11:00 AM on Thursday, February 6, 2023 (see Appendix A). The ambient noise levels were digitally measured and stored using one (1) Larson Davis SoundTrack LxT sound level meter that meets American National Standards Institute requirements for a Type 1 integrating sound level meter. The sound meter was calibrated immediately before and after the monitoring period using a reference one kilohertz (1kH) check frequency and 114 dB sound pressure level and found to be operating within normal parameters for sensitivity. Measurements were continuously collected over the sample period in 1-minute intervals. This interval was selected to capture long-term noise events and increases in noise levels above typical background conditions. Ambient noise measurements were also made using one Piccolo-II Integrating Averaging Sound Level Meter that meets the ANSI S1.43 Type 2 requirements for an integrated sound level meter. The sound meter was calibrated immediately before and after the monitoring period using a reference 1kH check frequency and 94 dB sound pressure level and found to be operating within normal parameters for sensitivity. Short-term measurements were periodically collected over sample periods in 1-minute intervals in order to capture short-term noise events and increases in noise levels above background conditions. Weather conditions during the monitoring were generally clear and sunny during the daytime and clear and cool during the nighttime. Temperatures ranged from 50 to 60 degrees Fahrenheit. Winds were generally light and variable and ranged from approximately 5 to 10 miles per hour (mph).
The ambient noise monitoring conducted for this Report included one (1) long-term (LT) and five (5) short-term (ST) measurement at locations selected to:
• Provide direct observations of existing noise sources at and in the vicinity of the proposed Project;
• Measure typical ambient noise levels at and in the vicinity of the proposed Project; and

As shown in Table 4-1 and Table 4-2, the measured ambient noise levels at and near the Project site are consistently above approximately 55 dBA Leq during the daytime, evening, and nighttime. Measured noise levels were higher closer to Slover Avenue (ST-4 and ST-5) than on the interior of the Project site (LT-1) due to higher traffic volumes on this road. The 24-hour noise exposure level at LT-1 was 67.7 dBA CNEL.
4.2.1.1 Discussion of Ambient Noise Levels at an Existing Warehouse/Business Park Use
In addition to collecting ambient noise data at the Project site, MIG has conducted ambient noise level monitoring at an existing, approximately 80,000 square-foot warehouse/business park use to inform potential project noise levels. The existing warehouse was located at 1900 East Alessandro Boulevard in the City of Riverside. The noise monitoring was conducted from approximately 8:30 AM to 3:00 PM on Tuesday, July 28, 2020, following the same procedures described in Section 4.2.1. Measurements were continuously collected over the sample period in 1-minute intervals. This interval was selected to capture short-term noise events and increases in noise levels above typical background conditions. Weather conditions during the monitoring were generally clear and sunny, with temperatures ranging from the low 80’s (in the morning) to the high 90’s (in the later afternoon). Winds were generally calm. The ambient noise monitoring included two (2) ST measurements at locations selected to:
• Provide direct observations and measurements of existing noise sources at and in the vicinity of the existing 80,000 square foot warehouse; and
• Determine typical ambient noise levels at and in the vicinity of the proposed Project; and
Environmental and Regulatory Framework Page 4-5
MIG, Inc – Fontana Citrus Industrial Building Project Noise and Vibration Report – July 2023
The existing warehouse ambient noise monitoring locations were generally located approximately 90 feet and 385 feet from the site’s entrance, approximately 50 feet from drive aisles/maneuvering areas, and approximately 115 feet from building façade/truck dock doors. Based on observations made during the ambient noise monitoring, the noise environment at a warehouse is a function of intermittent site usage, with noise levels increasing during truck unloading and loading activities and returning to background levels when truck docks are not in use. Table 4-3 summarizes the results of the existing warehouse ambient noise monitoring conducted previously by MIG. Refer to Appendix A for detailed ambient noise monitoring results.

Both sites were situated approximately 50 feet from the main drive aisle providing access to truck loading/unloading docks and approximately 100 feet from the building façade/truck dock doors.
4.2.2 NOISE SENSITIVE RECEPTORS
Noise sensitive land uses and receptors are buildings or areas where unwanted sound or increases in sound may have an adverse effect on people or land uses. The City’s General Plan defines noise as unwanted sound, and the Municipal Code defines sensitive noise receptors as any residence including private homes, condominiums, apartments, and living quarters, schools, preschools, daycare centers, in-home daycares, health facilities such as hospitals, long term care facilities, retirement and nursing homes, prisons, and dormitories (City of Fontana, 2018).
Based on the City’s General Plan and Municipal Code, the noise sensitive receptors near the proposed Project site include:
• Single-family residences on Boyle Avenue (north of the Project site) and Oleander Avenue (adjacent to the site’s eastern property line)
• Single-family residences west of the Project site across Citrus Avenue

4.3 FEDERAL, STATE, AND LOCAL NOISE REGULATIONS
4.3.1 FEDERAL NOISE AND VIBRATION REGULATIONS
There are no federal noise and vibration regulations that directly apply to the proposed Project, but the FTA’s 2018 Transit Noise and Vibration Impact Assessment Manual document sets groundborne vibration annoyance criteria for general assessments. The criteria vary by the type of building being subjected to the vibrations, and the overall number of vibration events occurring each day. The City’s General Plan references these criteria or evaluating human annoyance response to groundborne vibration (see Section 4.3.4.2).
4.3.2 STATE NOISE AND VIBRATION REGULATIONS
4.3.2.1 California Building Standards Code
The California Building Standards Code is contained in Title 24 of the California Code of Regulations and consists of 11 different parts that set various construction and building requirements. Part 2, California Building Code, Section 1207, Sound Transmission, establishes sound transmission standards for interior walls, partitions, and floor/ceiling assemblies. Specifically, Section 1207.4 establishes that interior noise levels attributable to exterior noise sources shall not exceed 45 dBA DNL or CNEL (as set by the local General Plan) in any habitable room.
The California Green Building Standards (CALGreen) Code is Part 11 to the California Building Standards Code. Chapter 5, Nonresidential Mandatory Standards, Section, establishes additional standards for interior noise levels:
1. Section 5.507.4.1.1 sets forth that buildings exposed to a noise level of 65 dB Leq (1-hour) during any hour of operation shall have exterior wall and roof-ceiling assemblies exposed to the noise source meeting a composting sound transmission class (STC) rating of at least 45 (or an outdoor indoor transmission class (OITC) of 35, with exterior windows of a minimum STC of 40. 2. Section 5.507.4.2 sets forth that wall and roof assemblies for buildings exposed to a 65 dBA Leq pursuant to Section 5.507.4.1.1, shall be constructed to provide an interior noise environment attributable to exterior sources that does not exceed 50 dBA Leq in occupied areas during any hour of operation. This requirement shall be documented by preparing an acoustical analysis documenting interior sound levels prepared by personnel approved by the architect or engineer of record.

5 NOISE IMPACT ANALYSIS
This chapter evaluates the potential for the proposed Project to result in direct and indirect changes to the existing noise and vibration environment in the vicinity of the Project area. Refer to Chapter 6 for information and disclosures about the existing noise and vibration environment’s effect and overall compatibility on the proposed Project.
5.1 THRESHOLDS OF SIGNIFICANCE
In accordance with Appendix G of the State CEQA Guidelines, the proposed Project could result in potentially significant impacts related to noise and vibration if it would:
• Generate a substantial temporary or permanent increase in ambient noise levels in the vicinity of the project in excess of the standards established in:
o City Municipal Code Section 18-62 and Section 18-63 (Prohibited Noise) and Section 30-543 (Industrial Zoning Districts); or
o General Plan Noise and Safety; or
• Generate excessive ground-borne vibration or ground-borne noise levels in excess of the standards established in:
o City Municipal Code Section 30-543; or
• Expose people residing or working in the Project area to excessive airport-related noise levels.
5.2 NOISE IMPACT ANALYSIS METHODOLOGY
The construction and operation of the proposed Project would generate noise and vibration. This section describes the Project’s noise sources and the methodologies used to estimate potential Project noise and vibration levels.
5.2.1 CONSTRUCTION NOISE
As described in Section 2.3.4 and shown in Table 2-3, the proposed Project would generate construction noise from the following sources:
• Heavy equipment operations throughout the Project area. Some heavy equipment would consist of mobile equipment such as a loader, excavator, etc. that would move around work areas; other equipment would consist of stationary equipment (e.g., air compressors) that would generally operate in a fixed location until work activities are complete. Heavy equipment generates noise from engine operation, mechanical systems and components (e.g., fans, gears, propulsion of wheels or tracks), and other sources such as back-up alarms. Mobile equipment generally operates at different loads, or power outputs, and produce higher or lower noise levels depending on the operating load. Stationary equipment generally operates at a steady power output that produces a constant noise level.
• Vehicle trips, including worker, vendor, and haul truck trips. These trips would occur on the roads that provide access to the Project site, Slover Avenue, Oleander Avenue, and Boyle Avenue.
Page 5-2 Noise Impact Analysis
MIG, Inc – Fontana Citrus Industrial Building Project Noise and Vibration Report – July 2023
Since Project-specific construction equipment information is not available at this time, potential construction-related noise impacts can only be evaluated based on the typical construction activities associated with a typical industrial warehousing development project. This Report estimates heavy-duty construction equipment noise levels using the FHWA’s Roadway Construction Noise Model (RCNM), Version 1.1. The RCNM is a computer program that uses empirical data and sound propagation principles to predict noise levels associated with a variety of construction equipment and operations. The equipment assumptions used in this Report are based on, and consistent with, the CalEEMod construction phasing, equipment usage, and operating schedules used to evaluate the proposed Project’s potential construction air quality impacts (MIG, 2023).
The RCNM was used to model noise levels at 12 different receptor locations that could be impacted by the project’s construction noise levels. The location of the modeled construction noise receptors is shown in Figure 5-1 and summarized in Table 5-1.
Construction noise was modeled for two scenarios:
• Worst Case Construction Noise Levels: This scenario models potential short-term construction equipment operations along the Project site’s property lines. Such operations are assumed to occur during the Project’s demolition, site preparation, grading, and paving phases. This scenario represents the shortest distance between potential Project construction activities and modeled noise receptors.
• Typical Construction Noise Levels: This scenario models typical, sustained construction equipment noise levels based on the geographic center of the likely work areas at the site. For site preparation and grading phases, typical construction equipment noise levels were modeled from the center of the Project site. For all other phases except demolition, typical construction equipment noise levels were modeled from the center of the site on the east and west sides of the proposed building.
The RCNM input distance between the closest edge of the work area to the modeled construction noise receptors is shown in Table 5-2.

5.2.2 OPERATIONAL NOISE
Once constructed, the proposed Project would generate noise from the following activities:
• Off-site vehicle travel on Boyle Avenue, Oleander Avenue, Slover Avenue, and Citrus Avenue. The proposed Project would generate 425 total daily passenger car trips and 80 total daily
Noise Impact Analysis Page 5-5
MIG, Inc – Fontana Citrus Industrial Building Project Noise and Vibration Report – July 2023
truck trips (equal to 505 total vehicle trips and 644 total passenger car equivalent (PCE) trips (Ganddini Group, 2023).2 The following describes the inbound and outbound vehicle travel patterns anticipated for the Project:
o Inbound Truck Trips. Sixty percent (60%) of inbound truck trips would access the site traveling southbound on Citrus Avenue and eastbound on Slover Avenue and turning into southcentral driveway. Forty percent (40%) of inbound truck trips would access the site by traveling westbound on Slover Avenue. Five percent (5%) of the truck trips would divert to the north on Oleander Avenue (i.e., at the Slover Avenue and Oleander intersection) before turning west on Boyle Avenue and accessing the site through the northeast driveway. The remaining 35% of truck trips from westbound Solver Avenue (prior to the Solve Avenue and Oleander Avenue intersection) would continue westbound on Slover Avenue and access the site via the southwestern driveway (10% of truck trips), the southcentral driveway (15% of truck trips), or the southeast driveway (10% of truck trips).
o Outbound Truck Trips. Sixty percent (60%) of outbound truck trips would exit by traveling westbound on Slover Avenue from the southern driveways (30% from the southwest, 25% from the southcentral, and 5% from the southeast) and turning north on Citrus Avenue at the Citrus-Slover intersection. Forty percent (40%) of outbound truck trips would travel eastbound on Slover Avenue, with 35% of truck trips exiting the site by traveling eastbound on Slover Avenue from the southcentral driveway and 5% of truck trips exiting the site by traveling eastbound on Boyle Avenue from the northwest driveway, turning south on Oleander Avenue, and then turning east on Slover Avenue.
o Inbound Passenger Vehicle Trips. Thirty percent (30%) of inbound passenger vehicle trips would access the site traveling southbound on Citrus Avenue. Fifteen percent (15%) of inbound passenger vehicle trips would access the site traveling eastbound on Slover Avenue (originating from west of Citrus Avenue). Five percent (5%) of inbound passenger vehicle trips would access the site traveling northbound on Citrus Avenue. Ten percent (10%) of inbound passenger vehicle trips would access the site traveling northbound on Oleander Avenue. Forty percent (40%) of inbound passenger vehicle trips would access the site traveling westbound on Slover Avenue (originating from east of Oleander Avenue). Sixty percent (60%) of inbound passenger vehicle trips would enter the site via the northern driveways on Boyle Avenue (15% into the northwest and 45% into the northeast). Forty percent (40%) of inbound passenger vehicle trips would enter the site via the southern driveways on Slover Avenue (10% into the southwest and 30% into the southeast).
o Outbound Passenger Vehicle Trips. Forty percent (40%) of outbound passenger vehicle trips would exit via the northern driveways on Boyle Avenue (10% from the northwest and 30% from the northeast). Sixty percent (60%) of outbound passenger vehicle trips would exit via the southern driveways on Slover Avenue (20% from the southwest and 40% from the southeast). Thirty percent (30%) of outbound passenger vehicle trips would travel eastbound on Slover Avenue. Five percent (5%) of outbound passenger vehicle trips
2 Passenger Car Equivalent (PCE) trips calculated to account for the additional capacity used by larger vehicles such as trucks. Truck trips were converted to PCE trips based on an equivalency factor of 2.0 (i.e., one truck trip is equal to approximately two passenger cars). (Ganddini Group, 2023).

would travel southbound on Oleander Avenue. Forty percent (40%) of outbound passenger vehicle trips would travel northbound on Citrus Avenue. Fifteen percent (15%) of outbound passenger vehicle trips would travel westbound on Slover Avenue. Ten percent (10%) of outbound passenger vehicle trips would travel southbound on Citrus Avenue.
• On-site passenger car travel along the site driveways and perimeter road/fire lane, automobile parking, and other miscellaneous automobile noise sources such as doors closing and engine start-up and revving. On-site automobile travel is assumed to occur at low speeds (15 mph).
• On-site truck travel along the site drive aisle to loading dock areas, truck maneuvering into and out of loading docks, and other miscellaneous sources such as engine start-up and revving, cab door closing, and release of compressed air from truck brake systems. Similar to automobiles, on-site truck travel is assumed to occur at low speeds (no more than 15 mph). According to the trip generation assessment prepared for the Project, truck trips are assumed to consist of 2-axle trips (16.7% of all truck trips), 3-axle trips (20.7% of all trips) large, heavy-duty 4-axle or more truck trips (62.6% of all truck trips). On-site idling was assumed to occur for up to 15 minutes per loading/unloading operation.
• Cargo management (i.e., forklifts) operations at truck docks. The proposed project would incorporate up to 43 electric-powered forklifts during operation as described in Section 2.3.3. Forklift operation and backup alarm was assumed to occur at each truck dock for approximately 30 minutes per loading/unloading operation.
• Rooftop mounted HVAC unit, assumed to be rated at 5 tons and generally located in the center of the office portion of the proposed building. The unit would be fully concealed behind a parapet or enclosure that would reduce potential HVAC unit noise levels.
• Other miscellaneous noise sources, such as landscaping equipment, garbage collection services, and other miscellaneous site operations (e.g., occasional electric power jack or pallet lift). These noise sources would be intermittent and would not substantially change overall Project noise levels. Therefore, these noise sources are not discussed further in this Report.
5.2.2.1 Operational Noise Level Estimates
The proposed Project’s operational noise levels were estimated using standard theoretical equations for predicting environmental noise levels (Caltrans, 2013). For an ideal point source of sound, the energy contained in a sound pressure wave dissipates and is absorbed by the surrounding environment as the sound wave spreads out in a spherical pattern and travels away from the point source. Theoretically, the sound level attenuates, or decreases, by 6 dB with each doubling of distance from the point source. The change in noise levels between two distances can be calculated according to Equation 1 as follows:
Noise Impact Analysis Page 5-7
MIG, Inc – Fontana Citrus Industrial Building Project Noise and Vibration Report – July 2023
Equation 1
dBA2 = dBA1 + 20log (D1/D2)
Where:
dBA1 = Known noise level, such as a reference noise level
D1 = Distance associated with dBA1
dBA2 = Noise level at distance 2
D2 = Distance associated with dBA2
For an ideal line source of sound, the energy contained in a sound pressure wave dissipates and is absorbed by the surrounding environment as the sound wave spreads out in a cylindrical pattern from the source. Theoretically, the sound level attenuates, or decreases, by 3 dB with each doubling of distance from the line source. The change in noise levels between two distances can be calculated according to Equation 2 as follows:
Equation 2
dBA2 = dBA1 + 10log (D1/D2)
Where:
dBA1 = Known noise level, such as a reference noise level
D1 = Distance associated with dBA1
dBA2 = Noise level at distance 2
D2 = Distance associated with dBA2
For noise sources that do not operate continuously (e.g., vehicles and trucks that travel on-site, park, and then cease to generate noise),the average, hourly noise level associated with variable (i.e., non-steady) noise source can be calculated using Equation 3 as follows:
Equation 3
Hourly Leq = 10 * Log (Ph) * 10(Lp/10) Where: Ph = Percentage or fraction of hour the noise is generated Lp = The noise level generated during the partial hour (Ph)
Finally, the total combined sound pressure level from multiple, identical sources of noise at a receiver location can be calculated using Equation 4 as follows:
Equation 4
SPLTotal = SPL1 + 10 * Log (N)
Where:
SPL1 = Sound pressure level of one source
N = Number of identical sources to be added
Reference and potential hourly average noise levels associated with the proposed Project’s noise sources are summarized in Table 5-3. All reference noise levels are presented at a distance of three (3) feet from the source.

5.2.3 GROUND-BORNE VIBRATION
Project construction activities would involve the use of large equipment capable of generating ground-borne vibrations. Since Project-specific construction equipment information is not available at this time, potential construction-related vibration impacts can only be evaluated based on the typical construction activities associated with a typical business park / warehousing development. This Report estimates potential construction vibration levels using methodologies, reference vibration levels, and other factors documented and contained in Caltrans’ Transportation and Construction Vibration Guidance Manual and the FTA’s Transit Noise and Vibration Impact Assessment Manual (Caltrans 2020 and FTA 2018). Reference vibration levels are vibrations from specific equipment or activity types that are well documented and for which usage is common practice in environmental vibration analyses. The equipment assumptions used in this Report are based on, and consistent with, the CalEEMod construction phasing, equipment usage, and operating schedules used to evaluate the proposed Project’s potential construction air quality impacts (MIG, 2023).

MIG, Inc – Fontana Citrus Industrial Building Project Noise and Vibration Report – July 2023
Like sound transmission through the air, the transmission of vibrations through the ground decreases with distance from the source of the vibration. Theoretically, the change in vibration levels between two distances can be calculated according to Equation 5 and Equation 6 as follows:
Equation 5
PPVEquipment = PPVRef x (25/d)^n (inches/second)
Where:
PPVEquipment = Known peak particle velocity (PPV) level at 25 feet
D = Distance from equipment to the receiver (feet)
n = Vibration attenuation rate given ground characteristics
Equation 6
Lv.distance = Lvref – 30log(D/25)
Where:
Lv.distance = The root mean square velocity level adjusted for distance (VdB)
Lvref = The source reference vibration level at 25 feet (VdB)
D = Distance from the equipment to the receiver (feet)
5.3 TEMPORARY CONSTRUCTION NOISE AND VIBRATION IMPACTS
The proposed Project’s short-term construction-related noise and vibration levels were estimated using project-specific information and standard noise and vibration estimation methodologies recommended by Caltrans, the FHWA, and FTA (see Section 5.2). The results of this modeling, and a discussion regarding the significance of the Project’s construction noise and vibration levels, are provided below.
5.3.1 TEMPORARY CONSTRUCTION NOISE LEVELS
Table 5-4 summarizes modeled construction equipment noise levels at residential and non-residential receptors in the vicinity of the Project site for each anticipated Project construction activity.
As shown in Table 5-4, the modeled worst-case construction noise level at any residential receptor location would be 94.4 dBA Leq. This would occur at the residence (R6) located east of the Project site during the Project’s grading phase. During typical construction periods, construction noise levels would not exceed 82 dBA Leq at any residential location, and would generally be less than 75 dBA Leq. These noise level estimates are based on peak equipment usage during each construction phase. As construction progresses within each phase, less equipment is usually required to perform activities and, therefore, less equipment noise is generated.
The City’s Municipal Code does not establish numeric standards for construction noise levels (e.g., 90 dBA Leq) but does limit construction activities to the hours of 7 AM to 6 PM during weekdays and 8 AM to 5 PM on Saturday (Municipal code Section 18-63). As shown in Table 5-4 and discussed above, the Project’s potential exterior construction noise levels would range from approximately 55 dBA Leq to 94 dBA Leq depending on the specific equipment in use and the distance between the equipment and adjacent residential properties. These noise levels would be approximately 9 dB to 38 dB above the existing ambient noise levels measured at the Project site (see Table 4-1 and Table 4-2). Although the City does not maintain a specific construction noise level standard, the temporary increase in noise levels associated with
Page 5-10 Noise Impact Analysis
MIG, Inc – Fontana Citrus Industrial Building Project Noise and Vibration Report – July 2023
the proposed construction activities could, at times, be substantial and have the potential to annoy adjacent residential receptors and/or interfere with the receptors normal use and enjoyment of their property.

(A) Worst case distances are measured between the Project property line and the receptor property line. (B) Typical distances are measured between the east and west parts of the site and the receptor property line or building façade.
Although Project construction may result in a substantial temporary increase in ambient noise levels, it is not anticipated to result in physical harm (e.g., temporary or permanent hearing loss or damage) to any sensitive noise receptor near the Project area for several reasons. First, the construction phases with the most large-equipment operations – site preparation and grading – are anticipated to occur for no more than 40 days (not necessarily consecutive) out of the Project’s approximately 10-month construction schedule. Second, during this 40-day period, the estimated worst-case noise levels would only occur at receptor locations during the time when multiple pieces of equipment are operating directly adjacent to that receptor. As equipment moves along the property line and throughout the site, noise levels would decrease at one receptor and increase at a different receptor. These worst-case conditions (i.e., multiple pieces of equipment operating directly adjacent to one specific receptor) are estimated to occur no more than four (4) hours a day for no more than several days. Thus, receptors would not be continuously exposed to the estimated worst-case noise levels (noise levels would decrease as equipment moves away and return to ambient conditions when construction ceases for the day). Finally, the estimated construction noise levels presented in Table 5-4 are exterior noise levels, whereas receptors would be likely to be inside residential buildings during active construction operations. Interior noise levels would be approximately 12 dBA to 30 dBA lower depending on façade construction and whether windows or doors were open or closed. Physiological effects occur when the human ear is subjected to extremely high noise levels (e.g., above 110 dBA) for a short period or prolonged exposure to high noise environments. For example, to protect workers from noise-induced hearing loss, the U.S. Occupational Safety and Health Administration (OSHA) limits worker noise exposure to 90 dBA as averaged over an 8-hour time period (29 CFR 1910.95). Similarly, the National Institute for Occupational Safety and Health (NIOSH) recommends workers limit noise exposure to no more than 85 dBA over an 8-hour period to protect against noise-induced hearing loss (NIOSH, 1998). Although unmitigated hourly construction noise levels may approach 88 dBA Leq to 94 dBA Leq during certain construction phases, such noise levels would not be sustained over an 8-hour period

(due to movement of equipment and changes in operations that occur during daily construction activities). Therefore, at worst-case, noise from construction activities may pose a temporary interference or annoyance effect on nearby sensitive receptors but would not result in adverse physiological effects on human receptors in the surrounding area.
To reduce the potential for Project construction activities to result in a substantial temporary increase in ambient noise levels in the vicinity of the Project site that could annoy adjacent residential receptors and/or interfere with the normal use and enjoyment of residential properties, MIG recommends Mitigation Measure NOI-1 be incorporated into the Project.
Mitigation Measure NOI-1: Reduce Construction Noise Levels. To reduce potential noise levels associated with construction of the proposed Project, the Applicant and/or its designated contractor, contractor’s representatives, or other appropriate personnel shall:
6) Notify Adjacent Land Use of Planned Construction Activities. This notice shall be provided at
least two weeks prior to the start of any construction activities, describe the noise control
measures to be implemented by the Project, and include the name and phone number of a designated contact for the Applicant and the City of Fontana responsible for handling
construction-related noise complaints (per action #5 below). This notice shall be provided to
the owner/occupants of all occupied properties within 250 feet of the Project site.
7) Restrict work hours/equipment noise. All construction-related work activities, including material
deliveries, shall be subject to the requirements of City Municipal Code Section 18-63.
Construction activities, including deliveries, shall only occur during the hours of 7:00 AM to 6:00 PM on weekdays and 8:00 AM to 5:00 PM on Saturdays. The Applicant and/or its
contractor shall post a sign at all entrances to the construction site informing contractors,
subcontractors, construction workers, etc. of this requirement. 8) Construction equipment selection, use, and noise control measures. The following measures
shall apply during construction activities:
a) Contractors shall use the smallest size equipment capable of safely completing work
activities. b) Construction staging shall occur as far away from the adjacent residential properties as
possible.
c) The Applicant and/or his contractor shall connect to existing electrical service at the site to avoid the use of stationary power generators. This measure shall be subject to the
approval of the local electric utility. If electric service is denied, the Applicant shall ensure
actions 3a, 3b, and 3d are implemented. d) All stationary noise-generating equipment such as pumps, compressors, and welding
machines shall be shielded and located as far from residential land uses as possible given
site and active work constraints. Shielding may consist of a three- or four-sided enclosure provided the structure/enclosure breaks the line of sight between the equipment and the
receptor and provided for proper ventilation and equipment operation.
e) Heavy equipment engines shall be equipped with standard noise suppression devices such as mufflers, engine covers, and engine/mechanical isolators, mounts, and be maintained in accordance with manufacturer’s recommendations during active construction activities.
f) Pneumatic tools shall include a noise suppression device on the compressed air exhaust.
Page 5-12 Noise Impact Analysis
MIG, Inc – Fontana Citrus Industrial Building Project Noise and Vibration Report – July 2023
g) No radios or other amplified sound devices shall be audible beyond the property line of the construction site.
9) Install Construction Noise Barrier. During all demolition, site preparation, grading, trenching, and structure foundation work (e.g., excavation, pad pour, etc.), the Applicant shall install and maintain a physical noise barrier along the eastern perimeter of the site. The noise barrier shall extend to a height of eight (8) feet above grade. Potential barrier options capable of reducing construction noise levels could include, but are not limited to:
a) A plywood or other barrier installed at-grade (or mounted to structures located at-grade, such as a K-Rail), and consisting of a solid material (i.e., free of openings or gaps other than weep holes) that has a minimum rated transmission loss value of 20 dB.
b) Commercially available acoustic panels or other products such as acoustic barrier blankets that have a minimum sound transmission class (STC) or transmission loss value of 20 dB.
c) Any combination of noise barriers and commercial products that have a minimum sound transmission class (STC) or transmission loss value of 20 dB.
The noise barrier may be removed following the completion of building foundation work (i.e., it is not necessary once framing and typical vertical building construction begins provided no other grading, foundation, etc. work is still occurring on-site). Furthermore, the noise barrier shall not be required if the 10-foot-tall perimeter concrete masonry unit wall included in the project’s site plan is fully constructed prior to the start of substantial demolition, site preparation, and grading activities at the site (i.e., only clearing and grubbing and grading necessary to access the site and install the perimeter wall may occur).
10) Prepare a Construction Noise Complaint Plan: The Applicant shall prepare a Construction Noise Complaint Plan that shall:
a) Identify the name and/or title and contact information (including phone number and email) for a designated Project and City representative responsible for addressing construction-related noise issues.
b) Includes procedures describing how the designated Project representative will receive, respond, and resolve construction noise complaints.
c) At a minimum, upon receipt of a noise complaint, the Project representative shall notify the City contact, identify the noise source generating the complaint, determine the cause of the complaint, and take steps to resolve the complaint.
The implementation of Mitigation Measure NOI-1 would reduce construction noise levels by 5 dBA to 10 dBA at individual receptor locations during the daytime. Based on the estimated worst-case scenario (94 dBA Leq), exterior noise levels at individual receptors could reach 84 dBA Leq to 89 dBA Leq for limited periods of time. Such noise levels would be similar to the maximum measured daytime noise levels in the project vicinity, but noticeably louder (approximately 12 dBA to 30 dBA) than the typical measured daytime noise levels (approximately 57 dBA Leq to 72 dBA Leq, see Table 5-4). Although worst-case noise levels could be noticeably louder than typical hourly daytime noise levels, Mitigation Measure NOI-1 would require the Applicant to provide advance warning of the proposed Project’s potentially noisy construction activities, restrict work hours to periods when humans are less sensitive to elevated noise levels in accordance with Municipal Code requirements, implement equipment noise control measures, install a temporary noise barrier between work areas and affected residences, and prepare and plan for potential unanticipated or
Noise Impact Analysis Page 5-13
MIG, Inc – Fontana Citrus Industrial Building Project Noise and Vibration Report – July 2023
unexpected construction noise issues. By providing advanced notice of loud construction activities and implementing equipment control measures and temporary noise barriers, the potential for sensitive residential receptors to be surprised or annoyed by loud exterior noises would be substantially reduced. In addition, daytime noise levels inside potential residential buildings would be approximately 12 dBA to 30 dBA lower, depending on whether windows and doors were open or closed. Thus, interior noise levels at individual receptors locations could potentially reach 54 dBA Leq to 77 dBA Leq during the daytime. At no time would the proposed Project’s exterior or interior construction noise be loud enough to result in physical harm to adjacent residential receptors. Finally, although worst-case construction noise levels could be noticeably louder than typical conditions, this impact would occur intermittently (anticipated to be no more than four (4) hours per day) for several days during the Project’s anticipated 40-day site preparation and grading phases, which would not constitute sustained or prolonged exposure to substantial temporary noise increases. The implementation of Mitigation NOI-1 would lower overall Project construction noise levels, reduce the potential for Project construction noise levels to surprise or annoy residential receptors, and reduce the potential for Project construction noise levels to interfere with normal use of residential properties. The implementation of Mitigation Measure NOI-1 would, therefore, render the proposed Project’s potential construction noise levels less than significant with mitigation.
5.3.2 TEMPORARY CONSTRUCTION VIBRATION LEVELS
The potential for ground-borne vibration and noise is typically greatest when vibratory or large equipment such as rollers, impact drivers, or bulldozers are in operation. For the proposed Project, these types of equipment would primarily operate during demolition, site preparation, grading, and paving work. This equipment would, at worst-case and for very limited period of times, operate adjacent to the site’s property lines and within approximately 30 feet of the residential building façade to the east of the site and approximately 35 feet of the Arco gas station building façade to the west of the site; however, most construction activities would generally take place hundreds of feet away from these building locations.3 A summary of predicted worst-case construction vibration levels is presented in Table 5-5.
As shown in Table 5-5, the proposed Project’s construction activities would have the potential to generate worst-case ground-borne vibration levels of approximately 0.145 in/sec PPV at non-residential buildings and 0.172 in /sec PPV at residential buildings, which could be strongly perceptible per the Caltrans criteria for continuous vibration sources identified in Table 4-5 (0.10 in/sec PPV). These vibration levels are associated with the operation of a vibratory roller approximately 10 feet from the Project boundary. As the vibratory roller (and other equipment) moves away from the property line, vibration levels would decrease but, in general, the operation of vibratory and non-vibratory construction equipment could produce vibration levels that may be perceptible to buildings within approximately 400 feet and 100 feet, respectively. It is noted the vibration estimates shown in Table 5-5 do not take into account differences in grade or other subsurface conditions that may limit vibration transmission. In addition, the vibration estimated shown in Table 5-5 do not consider any loss of vibratory energy associated with the transfer of vibrations across different medium (e.g., from the soil to a concrete foundation to a floor or wall assembly). The vibration estimates shown in Table 5-5, therefore, are likely to overestimate potential vibration levels associated with construction equipment.
3 The worst-case distance between potential vibration generating work areas and nearby building facades is as measured from the edge of paved/hardscaped areas to the building façade.

Source: FTA, 2018 and MIG (see Appendix B). (A) Values represent highest estimated ground-borne vibration level for vibratory roller and typical construction equipment (see Appendix B).
As shown in Table 5-5, the proposed Project’s potential construction activities would have the potential to be perceptible at residential and commercial receptor locations; however, the vibration levels that could be generated by potential construction activities would not be considered excessive for several reasons. First, potential worst-case construction vibrations would be intermittent, lasting only a few hours each day at any individual receptor. Second, potential worst-case construction vibrations would occur only when equipment operates directly adjacent to a receptor, which is not anticipated to last more than several days in total. Third, all construction activity would occur during the daytime, when human beings are less sensitive to vibrations, and would not interfere with evening or nighttime use of residences. Finally, potential construction vibrations would not result in physical damage to any building or structure because estimated worst-case vibration levels would be below Caltrans’ guidelines for damage to sensitive residential structures and commercial structures (0.3 in/sec and 0.5 in/sec PPV, respectively, see Table 4-4). For these reasons, the proposed Project would not result in excessive ground-borne vibration levels. This impact would be less than significant.
5.4 OPERATIONAL NOISE IMPACTS
Once constructed, the proposed Project would generate noise from on-site and off-site activities. On-site activities would include vehicle and truck travel, HVAC operations, and other miscellaneous site maintenance and operations activities. Off-site noise activities would include vehicle and truck travel on Citrus Avenue, Slover Avenue, Oleander Avenue, and Boyle Avenue. These noise sources are described in Section 5.2.2.
5.4.1 ON-SITE NOISE GENERATION ANALYSIS
The proposed Project’s potential noise levels were estimated using the reference and calculated hourly Leq noise levels identified in Table 5-3 above, adjusted for distance (between the noise source and property line) and activity levels (e.g., number of automobile trips, trucks idling, etc.). In general, the estimated noise levels are theoretical predictions; they do not account for potential reflection or partial shielding, atmospheric or ground absorption, or other excess attenuation factors. For multiple noise sources such as cars parking, trucks idling, HVAC units, etc., noise levels were modeled from a single location to conservatively aggregate noise levels from an area (i.e., overestimate noise levels coming from any single point). For the purposes of this analysis, the Project’s noise sources (HVAC units, parking areas, drive aisles, and truck dock bays) were treated as stationary noise sources. Although the noise generated
Noise Impact Analysis Page 5-15
MIG, Inc – Fontana Citrus Industrial Building Project Noise and Vibration Report – July 2023
from parking areas, drive aisles, and truck dock bays is primarily generated by cars and trucks (mobile sources) and not stationary sources, this analysis conservatively compares noise from these sources against the City’s exterior stationary source noise standards because noise from these areas would generally come from a fixed location (e.g., an idling truck, a parked car, etc.). In addition, it is assumed that all on-site travel would occur at slow speed (15 mph or less), and due to the short distance traveled on-site (as little as 250 feet to some dock locations), on-site truck travel would be similar to a stationary source (as compared to trucks travelling on Citrus Avenue, Slover Avenue, Oleander Avenue, or Boyle Avenue). Project noise levels were estimated at eight (8) property line receiver locations surrounding the site, as shown in Figure 5-2. Only Project noise sources within 700 feet of a noise receiver that had a direct line of sight to the receiver were included in the noise prediction estimates. The distance between property line receiver locations and the Project’s noise sources is shown in Table 5-6.

MIG, Inc – Fontana Citrus Industrial Building Project Noise and Vibration Report – July 2023
The following discusses the key assumptions made to estimate potential Project noise levels at noise receiver locations:
• Truck entrances: Truck entrances would be located on Boyle Avenue at the northwest portion of the site and Slover Avenue at the southwestern, southcentral, and southeastern portions of the site. Truck entrances include truck turns into and out of the facility and are assumed to produce an average hourly noise level of approximately 71.4 dBA at a distance of 3 feet (see Table 5-3).
• On-site passenger car parking: Parking areas were assumed to require vehicle travel/maneuvering, doors closing, and engine start/revving activities that would produce an average hourly noise level of approximately 64.9 dBA at a distance of 3 feet (see Table 5-3).
• On-site truck travel: Each on-site truck trip was assumed to travel at low speed (no more than 15 mph) and produce an average hourly noise level of 75.2 dBA at a distance of 3 feet (see Table 5-3). Truck travel lanes would include driveways along Boyle Avenue and Slover Avenue. The amount of peak on-site truck travel activity (34 total trips in the peak hour periods) was determined from the Project’s Vehicle Miles Traveled Screening Analysis (Ganddini Group, 2023).
• On-site truck maneuvering and idling: Loading dock areas were assumed to require truck travel and maneuvering, back-up alarms, air brake release, and other related activities that would produce an average hourly noise level of approximately 89.3 dBA at a distance of 3 feet (see Table 5-3). Dock areas would be located at least 195 feet from adjacent residential property lines to the east. A 10-foott high concrete screening wall would provide screening from the dock areas to adjacent property lines east of the project site. This wall would provide a minimum of 5 dBA attenuation of noise from the truck dock area.
• HVAC unit: An HVAC unit was assumed to operate for 40 minutes of each hour and produce an average hourly noise level of 80 dBA at a distance of 3 feet. HVAC units would be located behind a 3-foot parapet wall that would provide at least 5 dB of attenuation. The HVAC unit would be located in the center of office space area.

(A) “—” indicates noise source does not contribute to noise levels at the property line receiver because it is more than 700 feet away from the receptor or the receiver is shielded from the noise source by the proposed warehouse building.
(B) See Section 4.3.4.1. Since the proposed Project could be operational for 24 hours a day, the nighttime 65 dBA standard is used for comparison in this table.
As shown in Table 5-7, the proposed Project’s stationary noise sources would not generate noise levels that exceed the City’s Municipal Code exterior noise standards for residential land uses. This impact would be less than significant.
Noise Impact Analysis Page 5-19
MIG, Inc – Fontana Citrus Industrial Building Project Noise and Vibration Report – July 2023
5.4.1.2 Compliance with City Interior Noise Standards
As shown in Table 5-7, the proposed Project would not generate noise levels that exceed the City’s exterior noise standards for residential land uses. The maximum estimated hourly Leq values at any residential receptor (R8) would be 55.2 dBA Leq. Typical residential-type construction achieves a minimum of 12 to 30 db of exterior-to-interior noise reduction, depending on whether windows and doors are open or closed, which would be sufficient to ensure the City’s 45 dBA interior noise standard (Municipal Code Section 30-469) is met inside nearby residential buildings. This impact would be less than significant.
5.4.1.3 Compliance with City of Fontana General Plan
The Project’s consistency with the applicable policies of the City’s General Plan Chapter 11: Noise and Safety is summarized in Table 5-8.
Table 5-8: Project Consistency with Applicable General Plan Noise Policies
General Plan Noise and Safety Goal/Policy Consistency Analysis
Goal 8: The City of Fontana protects sensitive land uses from excessive noise by diligent planning through 2035.
Policy 2: Noise-tolerant land uses shall be guided into areas irrevocably committed to land uses that are noise-producing, such as transportation corridors.
Consistent. As discussed in Section 2.1.1, the proposed Project would be located in a light-industrial zoned area.
Policy 4: Noise spillover or encroachment from commercial, industrial and educational land uses shall be minimized into adjoining residential neighborhoods or noise-sensitive uses.
Consistent. As discussed above in Section 5.4.1, the Project operations would not generate noise levels exceeding the City’s exterior noise standards for residential or commercial land uses.
Goal 10: Fontana’s residents are protected from the negative effects of “spillover” noise.
Policy 1: Residential land uses and areas identified as noise-sensitive shall be protected from excessive noise from non-transportation sources including industrial, commercial, and residential activities and equipment.
Consistent. As discussed in Section 5.3, the proposed project’s temporary construction related noise with mitigation incorporated would not result in a significant impact to the surrounding land uses.
5.4.2 OFF-SITE OPERATIONAL NOISE LEVELS
The proposed Project would generate vehicle trips that would be distributed onto the local roadway system and potentially increase noise levels along travel routes. Caltrans considers a doubling of total traffic volume to result in a three (3) dBA increase in traffic-related noise levels (Caltrans, 2013). If the proposed Project would not result in a doubling of traffic volumes on the local roadway system, it would not result in a substantial permanent increase in traffic-related noise levels.
The proposed Project would result in a net increase in trip generation equal to 363 total vehicle trips, on a daily basis, which would be distributed onto Oleander Avenue, Slover Avenue, and Citrus Avenue (Ganddini Group, 2023). According to the City’s General Plan, average daily traffic (ADT) volumes on Citrus Avenue were estimated to be between approximately 5,600 and 34,600 for the road segment near the proposed Project. ADT volumes on Slover Avenue were estimated to be approximately 13,400 for the road segment near the proposed Project. ADT volumes were not described for Boyle Avenue or
Page 5-20 Noise Impact Analysis
MIG, Inc – Fontana Citrus Industrial Building Project Noise and Vibration Report – July 2023
Oleander Avenue (City of Fontana, 2018 Exhibit 9.5 Average Daily Trips). The addition of Project trips to these roadways would not result in a doubling of traffic volumes or a substantial change in off-site traffic noise levels. This impact would be less than significant.
5.5 AIRPORT-RELATED NOISE
As described in Section 2.1.2, the proposed Project is located approximately 7.4 miles east of the nearest runway associated with the Ontario International Airport. Therefore, the proposed Project would not expose people to excess continuous or single-event airport-related noise levels.

6 OTHER NOISE AND VIBRATION EFFECTS
The California Supreme Court in California Building Industry Association v. Bay Area Air Quality Management District, 62 Cal.4th 369 (2015) ruled that CEQA review is focused on a project’s impact on the environment “and not the environment’s impact on the project.” Per this ruling, a Lead Agency is not required to analyze how existing conditions might impact a project’s future users or residents; however, a Lead Agency may elect to disclose information relevant to a project even if it not is considered an impact under CEQA.
This chapter discusses the existing noise environment and the degree to which the existing environment is compatible and consistent with City goals, policies, and standards for the proposed Project’s noise environment.
6.1 REVIEW STANDARDS
The existing noise environment described in Section 4.2 is reviewed against the following goals, policies, and standards. Would the Project:
• Expose people working in the project area to existing noise levels that exceed the standards established in:
o General Plan Noise and Safety; or
o The California Building Code.
6.2 LAND USE COMPATIBILITY – EXTERIOR NOISE EXPOSURE
The City’s General Plan Noise and Safety does not establish noise and land use compatibility standards for industrial land uses because such land uses are not considered to be noise-sensitive uses. As described in Section 4.2.1, the 24-hour CNEL value at LT-1 was determined to be 67.7 dBA CNEL (see Table 4-1). This CNEL value is within the normally acceptable noise level (75 CNEL) identified for industrial land uses in the Governor’s Office of Planning and Research (OPR) most recently published General Plan Guidelines (OPR, 2020, Appendix D Figure 2). The proposed Project, therefore, would not be exposed to unacceptable exterior noise levels that exceed City General Plan noise and land use compatibility standards.
6.3 INTERIOR NOISE LEVEL COMPATIBILITY
Part 2, California Building Code, Section 1206.4 establishes that interior noise levels attributable to exterior noise sources shall not exceed 45 dBA DNL or CNEL (as set by the local General Plan) in any habitable room. In addition, Chapter 5 of the California Green Building Standards Code sets forth that buildings exposed to a noise level of 65 CNEL (where noise contours are available) or 65 dBA Leq (1-hour where noise levels are not available) shall: 1) have exterior wall and roof-ceiling assemblies exposed to the noise source that meeting a composite STC rating of at least 50 (or a composite OITC) rating no less than 40, with exterior windows of a minimum STC of 40 or OITC 30 (Section 5.507.4.1); or 2) provide an interior noise environment attributable to exterior sources that does not exceed 50 dBA Leq in occupied areas during any hour of operation. In addition, County Code Section 83.01.080 (h) sets forth that warehousing areas shall be sound attenuated to meet an interior sound level of 65 dBA.
As described above, the proposed building’s southern façade would be subjected to noise levels of approximately 70.4 dBA CNEL. Standard construction techniques and materials for new
Page 6-2 Other Noise and Vibration Issues
MIG, Inc – Fontana Citrus Industrial Building Project Noise and Vibration Report – July 2023
commercial/industrial buildings are commonly accepted to provide a minimum exterior to interior noise attenuation (i.e., reduction) of 30 to 32 dBA with all windows and doors closed, which would result in interior noise levels of approximately 41 dBA Leq for occupied rooms fronting Slover Avenue.4 Thus, with standard construction techniques, the proposed Project would satisfy interior building code noise requirements.
4 The U.S. Department of Housing and Urban Development (HUD) Noise Guidebook and supplement (2009a, 2009b) includes information on noise attenuation provided by building materials and different construction techniques. As a reference, a an exterior wall consisting solely of 4 x 8 x 16, 3-cell lightweight concrete masonry units with a density of 17 pounds per block has an STC rating of 40. This reduction may be slightly lower (2-3 dBs) for traffic noise due to the specific frequencies associated with traffic noise.
