SUBJECT: SIERRA BUSINESS CENTER (COMPRISED OF THE SIERRA INDUSTRIAL FACILITY [SHEA PROJECT]
& NORTH FONTANA INDUSTRIAL COMPLEX [ACACIA PROJECT]) NOISE ASSESSMENT
Dear Ms. Tracy Zinn:
Urban Crossroads, Inc. is pleased to provide the following Noise Assessment for the Sierra Business
Center development (referred to as “Project”) located east of Sierra Avenue and south of Duncan
Canyon Road in the City of Fontana. The Project includes two separate and independent but adjacent
projects: the Sierra Industrial Facility (Shea Project) and the North Fontana Industrial Complex (Acacia
Project). The purpose of this Noise Assessment is to describe the cumulative off-site traffic noise level
increases, as well as the operational and construction noise impacts both the Acacia and Shea projects
since they are adjacent to one another and are expected to be entitled and constructed on similar
timeframes.
The Shea Project provides for the development of an approximately 11.1-acre site with a single
commerce center building with a maximum of 199,999 sf, including up to 19,900 sf of office space. The
structure would be supported by a screened truck yard and trailer storage area along the south side of
the structure, vehicular parking areas, drive aisles, and landscaping. The typical height of the building
is designed to reach 41.0 feet above finished floor elevation; however, the building would have a
varied roofline and the maximum height (including parapets) would extend to 46.0 feet above finished
floor elevation. The building would be constructed of tilt-up panels and low-reflective, blue glass. The
Shea Project would require a General Plan Amendment and a Zone change, revising the General Plan
designation from Multi-Family High Density Residential (R-MFH) to Light Industrial (I-L) and the zoning
designation from Multi-Family High Density Residential (R-5) to Light Industrial (M-1).
The Acacia Project provides for the development of an approximately 19.0-acre site with two
commerce center buildings with a total maximum of 385,043 square feet (sf). Building 1 would consist
of 296,297 sf and Building 2 would consist of 88,746 sf. The structures would be supported by a
screened truck yard and trailer storage area along the south side of Building 1 and the west side of
Building 2, vehicular parking areas, drive aisles, and landscaping. The typical heights of both Building 1
and Building 2 are designed to reach 40 feet 6 inches above finished floor elevation; however, the
buildings would have a varied roofline and the maximum height (including parapets) would extend to
45 feet 6 inches above finished floor elevation. Both buildings would be constructed of tilt-up panels
and low-reflective, blue glass. The Acacia Project would require a General Plan Amendment and a

and General Commercial (C-G) to Light Industrial (I-L) and the zoning designation from Multi-Family
High Density Residential (R-5) and General Commercial (C-2) to Light Industrial (M-1).
OFF-SITE TRAFFIC NOISE METHODS AND PROCEDURES
The following section outlines the methods and procedures used to estimate and analyze the future
traffic noise environment needed to describe the off-site Project-related traffic noise level increases.
FHWA TRAFFIC NOISE PREDICTION MODEL
The expected roadway noise level increases from vehicular traffic were calculated by Urban
Crossroads, Inc. using a computer program that replicates the Federal Highway Administration (FHWA)
Traffic Noise Prediction Model- FHWA-RD-77-108. (1) The FHWA Model arrives at a predicted noise
level through a series of adjustments to the Reference Energy Mean Emission Level (REMEL). In
California the national REMELs are substituted with the California Vehicle Noise (Calveno) Emission
Levels. (2) Adjustments are then made to the REMEL to account for: the roadway classification (e.g.,
collector, secondary, major or arterial), the roadway active width (i.e., the distance between the center
of the outermost travel lanes on each side of the roadway), the total average daily traffic (ADT), the
travel speed, the percentages of automobiles, medium trucks, and heavy trucks in the traffic volume,
the roadway grade, the angle of view (e.g., whether the roadway view is blocked), the site conditions
("hard" or "soft" relates to the absorption of the ground, pavement, or landscaping), and the
percentage of total ADT which flows each hour throughout a 24-hour period. Research conducted by
Caltrans has shown that the use of soft site conditions is appropriate for the application of the FHWA
traffic noise prediction model used in this analysis. (3)
OFF-SITE TRAFFIC NOISE PREDICTION MODEL INPUTS
Table 1 presents the roadway parameters used to assess the Project-related off-site traffic noise level
increases. Table 1 identifies the six off-site study area roadway segments, the distance from the
centerline to adjacent land use based on the functional roadway classifications per the City of Fontana
General Plan, and the posted vehicle speeds. The without project ADT volumes used in this study area
presented on Table 2 are based on North Fontana Industrial Complex (Acacia) Traffic Study by Urban
Crossroads, Inc. for the following traffic scenarios. (4)
1. Existing (2021)
2. Existing (2021) plus Project (E+P)
3. Existing plus Ambient Growth without Project (EA)
4. Existing plus Ambient Growth with Project (EAP) (Acacia + Shea Sites)
5. Opening Year Cumulative (2024) without Project (OYC)
6. Opening Year Cumulative (2024) with Project (OYCP)

The ADT volumes vary for each roadway segment based on the existing traffic volumes and the
combination of (Acacia + Shea Sites) Project trip generation. This analysis relies on a comparative
evaluation of the off-site traffic noise impacts at the boundary of the right-of-way of the receiving
adjacent land use, without and with project ADT traffic volumes.

To quantify the off-site noise levels, the Project related truck trips were added to the heavy truck
category in the FHWA noise prediction model. The addition of the Project related truck trips increases
the percentage of heavy trucks in the vehicle mix. This approach recognizes that the FHWA noise
prediction model is significantly influenced by the number of heavy trucks in the vehicle mix.

Table 3 provides the time of day (daytime, evening, and nighttime) vehicle splits. Table 4 shows the
traffic flow by vehicle type (vehicle mix) used for all without Project traffic scenarios, and Tables 5 to 7
show the vehicle mixes used for the with Project (Acacia + Shea Sites) traffic scenarios. Due to the
added Project truck trips, the increase in Project traffic volumes and the distributions of trucks on the
study area road segments, the percentage of autos, medium trucks and heavy trucks will vary for each
of the traffic scenarios. This explains why the existing and future traffic volumes and vehicle mixes
vary between seemingly identical study area roadway segments.

OFF-SITE TRAFFIC NOISE ANALYSIS
To assess the off-site traffic CNEL noise level impacts associated with the Project, noise contours were
developed based on an estimate of without and with (Acacia + Shea Sites) Project traffic volumes.
Noise contours were used to assess the Project’s incremental 24-hour dBA CNEL traffic-related noise
impacts at land uses adjacent to roadways conveying Project traffic. Noise contour boundaries
represent the equal levels of noise exposure and are measured in CNEL from the center of the
roadway. The noise contours represent the distance to noise levels of a constant value and are
measured from the center of the roadway for the 70, 65, and 60 dBA CNEL noise levels. The noise
contours do not consider the effect of any existing noise barriers or topography that may attenuate
ambient noise levels. In addition, because the noise contours reflect modeling of vehicular noise on
area roadways, they appropriately do not reflect noise contributions from the surrounding stationary
noise sources within the Project study area. Tables 8 through 13 present a summary of the exterior

OFF-SITE TRAFFIC NOISE LEVEL INCREASES
Noise level increases resulting from the Project are evaluated based on the Appendix G CEQA
Guidelines. Under CEQA, consideration must be given to the magnitude of the increase, the existing
baseline ambient noise levels, and the location of receivers to determine if a noise increase represents
a significant adverse environmental impact. This approach recognizes that there is no single noise
increase that renders the noise impact significant. (5) This is primarily because of the wide variation in
individual thresholds of annoyance and differing individual experiences with noise. Thus, an important
Ms. Tracy Zinn
T&B Planning Inc.

way of determining a person’s subjective reaction to a new noise is the comparison of it to the existing
environment to which one has adapted—the so-called ambient environment. In general, the more a
new noise exceeds the previously existing ambient noise level, the less acceptable the new noise will
typically be judged. The Federal Interagency Committee on Noise (FICON) (6) developed guidance to
be used for the assessment of project-generated increases in noise levels that consider the ambient
noise level. The FICON recommendations are based on studies that relate aircraft noise levels to the
percentage of persons highly annoyed by aircraft noise. Although the FICON recommendations were
specifically developed to assess aircraft noise impacts, these recommendations are often used in
environmental noise impact assessments involving the use of cumulative noise exposure metrics, such
as the average-daily noise level (CNEL) and equivalent continuous noise level (Leq).
As previously stated, the approach used in this noise study recognizes that there is no single noise
increase that renders the noise impact significant, based on a 2008 California Court of Appeal ruling on
Gray v. County of Madera. (5) For example, if the ambient noise environment is quiet (<60 dBA) and
the new noise source greatly increases the noise levels, an impact may occur if the noise criteria may
be exceeded. Therefore, for this analysis, a readily perceptible 5 dBA or greater project-related noise
level increase is considered a significant impact when the without project noise levels are below 60
dBA. Per the FICON, in areas where the without project noise levels range from 60 to 65 dBA, a 3 dBA
barely perceptible noise level increase appears to be appropriate for most people. When the without
project noise levels already exceed 65 dBA, any increase in community noise louder than 1.5 dBA or
greater is considered a significant impact if the noise criteria for a given land use is exceeded, since it
likely contributes to an existing noise exposure exceedance. The FICON guidance provides an
established source of criteria to assess the impacts of substantial temporary or permanent increase in
baseline ambient noise levels. Based on the FICON criteria, the amount to which a given noise level
increase is considered acceptable is reduced when the without Project (baseline) noise levels are
already shown to exceed certain land-use specific exterior noise level criteria. The specific levels are
based on typical responses to noise level increases of 5 dBA or readily perceptible, 3 dBA or barely
perceptible, and 1.5 dBA depending on the underlying without Project noise levels for noise-sensitive
uses. These levels of increases and their perceived acceptance are consistent with guidance provided
by both the Federal Highway Administration (7 p. 9) and Caltrans (8 p. 2_48).
EXISTING PROJECT TRAFFIC NOISE LEVEL INCREASES
An analysis of existing traffic noise levels plus traffic noise generated by the proposed Project has been
included in this report for informational purposes and to fully analyze all the existing traffic scenarios
identified in the Traffic Study. However, the analysis of existing off-site traffic noise levels plus traffic
noise generated by the proposed Project scenario will not actually occur since the Project would not be
fully constructed and operational until 2024 conditions. Table 8 shows the Existing without Project
conditions CNEL noise levels. The Existing without Project exterior noise levels range from 59.3 to 76.5
dBA CNEL, without accounting for any noise attenuation features such as noise barriers or topography.
Table 9 shows the Existing with Project conditions ranging from 60.5 to 76.7 dBA CNEL. Table 14 shows
Ms. Tracy Zinn
T&B Planning Inc.

14283-08 Sierra Business Center Noise
that the Project off-site traffic noise level increases range from 0.0 to 1.2 dBA CNEL on the study area
roadway segments. Based on the significance criteria for off-site traffic noise, land uses adjacent to the
study area roadway segments would experience less than significant noise level impacts due to
unmitigated Project-related traffic noise levels.
EA TRAFFIC NOISE LEVEL INCREASES
Table 10 presents the EA 2024 without Project conditions CNEL noise levels. The EA without Project
exterior noise levels range from 59.6 to 76.7 dBA CNEL, without accounting for any noise attenuation
features such as noise barriers or topography. Table 11 shows that the EA with Project conditions will
range from 60.7 to 76.9 dBA CNEL. Table 15 shows that the Project off-site traffic noise level increases
range from 0.0 to 1.1 dBA CNEL on the study area roadway segments. Based on the significance
criteria for off-site traffic noise, land uses adjacent to the study area roadway segments would
experience less than significant noise level impacts due to unmitigated Project-related traffic noise
levels.
OYC 2024 TRAFFIC NOISE LEVEL INCREASES
Table 12 presents the OYC 2024 without Project conditions CNEL noise levels. The OYC 2024 without
Project exterior noise levels range from 59.6 to 77.2 dBA CNEL, without accounting for any noise
attenuation features such as noise barriers or topography. Table 13 shows that the OYC 2024 with
Project conditions will range from 60.7 to 77.4 dBA CNEL. Table 16 shows that the Project off-site
traffic noise level increases range from 0.0 to 1.1 dBA CNEL on the study area roadway segments.
Based on the significance criteria for off-site traffic noise, land uses adjacent to the study area roadway
segments would experience less than significant noise level impacts due to unmitigated Project-related
traffic noise levels.

NOISE PREDICTION MODEL
To fully describe the exterior operational and construction noise levels from the Project, Urban
Crossroads, Inc. developed a noise prediction model using the CadnaA (Computer Aided Noise
Abatement) computer program. CadnaA can analyze multiple types of noise sources using the spatially
accurate Project site plan, georeferenced Nearmap aerial imagery, topography, buildings, and barriers
in its calculations to predict outdoor noise levels. Using the ISO 9613-2 protocol, CadnaA will calculate

14283-08 Sierra Business Center Noise
the distance from each noise source to the noise receiver locations, using the ground absorption,
distance, and barrier/building attenuation inputs to provide a summary of noise level at each receiver
and the partial noise level contributions by noise source. The noise level calculations provided in this
noise assessment account for the distance attenuation provided due to geometric spreading, when
sound from a localized stationary source (i.e., a point source) propagates uniformly outward in a
spherical pattern. A default ground attenuation factor of 0.5 was used in the noise analysis to account
for mixed ground representing a combination of hard and soft surfaces.
OPERATIONAL NOISE
This section analyzes the potential stationary-source operational noise impacts at the nearby receiver
locations resulting from the operation of the proposed Sierra Business Center Project. Using the same
approach for the Shea and Acacia projects, this operational noise analysis is intended to describe noise
level impacts associated with the expected typical of daytime and nighttime activities from the
combined Sierra Business Center Project site. The on-site Sierra Business Center related noise sources
are expected to include loading dock activity, roof-top, air-conditioning units, trash enclosure activity,
parking lot vehicle movements, and truck movements. Exhibit A identifies the noise source locations
used to assess the operational noise levels.
OPERATIONAL NOISE LEVEL COMPLIANCE
To demonstrate compliance with local noise regulations, the Project-only operational noise levels are
evaluated against exterior noise level thresholds based on the City of Fontana and the City of Rialto
exterior noise level standards at nearby noise-sensitive receiver locations. Table 17 shows that the
operational noise levels associated with Sierra Business Center Project will satisfy the City of Fontana
and the City of Rialto daytime and nighttime hourly exterior noise level standards at all nearby receiver
locations. Therefore, the operational noise impacts are considered less than significant at the nearby
noise-sensitive receiver locations. Appendix B includes the detailed noise model inputs and
calculations used to estimate the Project operational noise levels presented in this section.

"Daytime" = 7:00 a.m. to 10:00 p.m.; "Nighttime" = 10:00 p.m. to 7:00 a.m.
PROJECT OPERATIONAL NOISE LEVEL INCREASES
To describe the Project operational noise level increases, the Project operational noise levels are
combined with the existing ambient noise levels measurements for the nearby receiver locations
potentially impacted by Project operational noise sources. Since the units used to measure noise,
decibels (dB), are logarithmic units, the Project-operational and existing ambient noise levels cannot be
combined using standard arithmetic equations. (9) Instead, they must be logarithmically added using
the following base equation:
SPLTotal = 10log10[10SPL1/10 + 10SPL2/10 + … 10SPLn/10]
Where “SPL1,” “SPL2,” etc. are equal to the sound pressure levels being combined, or in this case, the
Project-operational and existing ambient noise levels. The difference between the combined Project
and ambient noise levels describes the Project noise level increases to the existing ambient noise
environment. As indicated on Table 18, the Project will generate a daytime noise operational level
increase ranging from 0.7 to 1.6 dBA Leq at the nearest receiver locations. Table 19 shows that the
Project will generate a nighttime operational noise level increase ranging from 1.0 to 4.6 dBA Leq at the
nearest receiver locations. A review of the operational noise level increases shows that the nighttime
increases are somewhat higher than the daytime increases. This is largely due to the lower nighttime
ambient conditions that when combined with the Project produce a higher relative increase.
The project-related operational noise level increases will satisfy the operational noise level increase
significance criteria. Therefore, the incremental Project operational noise level increase is considered
less than significant at all receiver locations.

CONSTRUCTION NOISE
This section analyzes potential impacts resulting from the short-term construction activities associated
with the development of the Project. Exhibit B shows the construction activity boundaries in relation
to the nearest sensitive receiver locations
CONSTRUCTION NOISE SOURCES
To describe construction noise activities, this construction noise analysis was prepared using reference
construction equipment noise levels from the Federal Highway Administration (FHWA) published the
Roadway Construction Noise Model (RCNM), which includes a national database of construction
equipment reference noise emission levels. (10) The RCNM equipment database, provides a
comprehensive list of the noise generating characteristics for specific types of construction equipment.
In addition, the database provides an acoustical usage factor to estimate the fraction of time each
piece of construction equipment is operating at full power (i.e., its loudest condition) during a
construction operation.
Using the reference construction equipment noise levels and the CadnaA noise prediction model,
calculations of the Project construction noise level impacts at the nearby sensitive receiver locations
were completed. Consistent with FTA guidance for general construction noise assessment, the Project
construction noise analysis relies on the combined noise levels for the loudest construction equipment,
assuming they operate at the same time, with the highest reference noise level of 83 dBA Leq.
Appendix C includes the detailed CadnaA construction noise model inputs.
CONSTRUCTION NOISE LEVEL COMPLIANCE
The construction noise analysis shows that the highest construction noise levels will occur when
construction activities take place at the closest point from the edge of primary construction activity to
each of the nearby receiver locations. Project construction noise levels are considered exempt if
activities occur within the hours specified in the City of Fontana Municipal Code, Section 18-63(7) of
7:00 a.m. to 6:00 p.m. on weekdays and between the hours of 8:00 a.m. to 5:00 p.m. on Saturdays.
If Project construction activity occurs outside of the hours specified in the Municipal Code, noise levels
shall satisfy the City of Fontana construction noise level thresholds of 70 dBA Leq during the daytime
hours and 65 dBA Leq during the nighttime hours. No Project construction activity is planned within the
hours specified in the City of Fontana Municipal Code, Section 18-63(7). As shown on Table 20, the
noise impacts due to project construction noise is considered less than significant at all receiver
locations.

4 Do the estimated Project construction noise levels exceed the construction noise level threshold during the

NIGHTTIME CONCRETE POUR NOISE ANALYSIS
Nighttime concrete pouring activities are often used to support reduced concrete mixer truck transit
times and lower air temperatures than during the daytime hours and are generally limited to the actual
building pad area as shown on Exhibit C. Since the nighttime concrete pours will take place outside the
permitted City of Fontana Municipal Code, Section 18-63(b)(7) hours of 7:00 a.m. and 6:00 p.m. on
weekdays and between the hours of 8:00 a.m. and 5:00 p.m. on Saturdays the Project Applicant will be
required to obtain authorization for nighttime work from the City of Fontana. Any nighttime
construction noise activities shall satisfy the residential noise limit categories.
NIGHTTIME CONCRETE POUR REFERENCE NOISE LEVEL MEASUREMENTS
To estimate the noise levels due to nighttime concrete pour activities, sample reference noise level
measurements were taken during a nighttime concrete pour at a construction site. Urban Crossroads,
Inc. collected short-term nighttime concrete pour reference noise level measurements during the
noise-sensitive nighttime hours between 1:00 a.m. to 2:00 a.m. The reference noise levels describe the
expected concrete pour noise sources that may include concrete mixer truck movements and pouring
activities, concrete paving equipment, rear mounted concrete mixer truck backup alarms, engine
idling, air brakes, generators, and workers communicating/whistling. To describe the nighttime
concrete pour noise levels associated with the construction of the Sierra Business Center, this analysis
relies on reference sound power level of 100.3 dBA Lw. While the Project noise levels will depend on
the actual duration of activities and specific equipment fleet in use at the time of construction, the
Ms. Tracy Zinn

14283-08 Sierra Business Center Noise
reference sound power level of 100.3 dBA Lw is used to describe the expected Project nighttime
concrete pour noise activities.
NIGHTTIME CONCRETE POUR NOISE LEVEL COMPLIANCE
As shown on Table 21, the noise levels associated with the nighttime concrete pour activities are
estimated to range from 31.8 to 48.0 dBA Leq and will satisfy the City of Fontana 65 dBA Leq nighttime
stationary-source exterior hourly average Leq residential noise level threshold at all the receiver
locations. Based on the results of this analysis, all nearest noise receiver locations will experience less
than significant impacts due to the Project related nighttime concrete pour activities. Appendix D
includes the CadnaA nighttime concrete pour noise model inputs.

CONSTRUCTION VIBRATION ANALYSIS
Construction activity can result in varying degrees of ground vibration, depending on the equipment
and methods employed. Operation of construction equipment causes ground vibrations that spread
through the ground and diminish in strength with distance. Ground vibration levels associated with
various types of construction equipment are summarized on Table 22. Based on the representative
vibration levels presented for various construction equipment types, it is possible to estimate the
potential for human response (annoyance) and building damage using the following vibration
assessment methods defined by the FTA. To describe the vibration impacts the FTA provides the
following equation: PPVequip = PPVref x (25/D)1.5
TABLE 22: VIBRATION SOURCE LEVELS FOR CONSTRUCTION EQUIPMENT
Equipment PPV (in/sec)
at 25 feet
Small bulldozer 0.003
Jackhammer 0.035
Loaded Trucks 0.076
Large bulldozer 0.089
Federal Transit Administration, Transit Noise and Vibration Impact Assessment Manual
Table 23 presents the expected Project related vibration levels at the nearby receiver locations. At
distances ranging from 58 to 1,397 feet from Project construction activities, construction vibration
velocity levels are estimated to range from 0.000 to 0.025 in/sec PPV. Based on maximum acceptable
continuous vibration threshold of 0.3 PPV (in/sec), the typical Project construction vibration levels will
fall below the building damage thresholds at all the noise sensitive receiver locations. Therefore, the
Project-related vibration impacts are considered less than significant during typical construction
activities at the Project site. Moreover, the vibration levels reported at the sensitive receiver locations
are unlikely to be sustained during the entire construction period but will occur rather only during the
times that heavy construction equipment is operating adjacent to the Project site perimeter.

CONCLUSIONS
This Noise Assessment demonstrates that the off-site study area roadway segments will experience
less than significant Project-related traffic noise level increases. In addition, the operational noise
levels associated with Sierra Business Center Project will satisfy the City of Fontana exterior noise level
standards at all nearby receiver locations. Therefore, the operational noise impacts are considered less
than significant at the nearby noise-sensitive receiver locations and the Project construction noise is
not expected to result in significant noise impacts. If you have any questions, please contact me
