EXECUTIVE SUMMARY

Acoustics Group, Inc., (AGI) has conducted a noise study of the Kerry’s Auto Project in
Chandler, AZ. The Kerry’s Auto’s Site Plan has been reviewed, noise measurements
conducted, noise levels analyzed, and an impact assessment performed to determine
compliance with the City of Chandler Noise Ordinance.

Noise from future equipment operations would be as high as 52 dBA at the office
boundary to the east (NM1), 46.2 dBA at the residential boundary to the south (NM2), 36
dBA at the residential boundary to the west (NM3), 41.3 dBA at the residential boundary
to the north (NM4) and 53.8 dBA at the commercial boundary to the north (NM5),
respectively. When combined with the ambient background noise, the increase in noise
level above the ambient baseline will be 0.8 dB at NM1, 0.1 dB at NM2, 0.0 dB at NM3,
0.1 dB at NM4 and 0.1 dB at NM5. The increase in noise level attributed to the future
operational noise levels will be less than significant and will not result in significant noise
impacts at any of the nearby boundary locations.

Noise from pneumatic tools, tire dismounting/mounting, air compressors and general
operations has the potential to be audible at the nearest residences, commercial and
office boundaries when there are lulls in the ambient background noise. However, during
periods of less intense activity or when the ambient background noise is higher such as
during the midday or afternoon, noise from the repair shop would be less noticeable.
Noise control measures are identified to minimize the potential for annoyance on the
nearest receivers.

This report has been organized into multiple sections for ease of reference. Section 1
introduces the Project and provides a general discussion on the Project Components.
Section 2 discusses Noise Fundamentals, and Section 3 presents the Noise Standards.
Section 4 discusses the Existing Noise Environment; Section 5 discusses the Noise
Analysis and Section 6 discusses the Impact Assessment. Section 7 presents the Noise
Control Measures. Section 8 discusses the Conclusion.

INTRODUCTION

Kerry’s Auto proposes a new auto service center at 1071 S. Cooper Rd. in Chandler, AZ.
The future facility will operate from 7:00 AM to 7:00 PM Monday through Friday, 7:00 AM
to 5:00 PM Saturday, and closed on Sunday. Refer to Figure 1 for the general location of
the Site and a Vicinity Map. Land uses immediately surrounding the site are commercial
and residential. Approximately 6-ft high noise barrier walls protect the residential land
uses to the south, west, and north of the project site. The main noise concern is future
automotive repair operations affecting the neighboring residential and office properties.
Refer to the Appendix for the Project Drawings.

NOISE

The magnitude by which noise affects its surrounding environment is measured on a
logarithmic scale in decibels (dB). Because the human ear is limited to hearing a specific
range of frequencies, the A-weighted filter system is used to form relevant results. A-
weighted sound levels are represented as dBA. Figure 2 shows typical A-weighted
exterior and interior noise levels that occur in human environments.

Several noise metrics have been developed to evaluate noise. Leq is the energy average
noise level and corresponds to a steady-state sound level that has the same acoustical
energy as the sum of all the time varying noise events. Lmax is the maximum noise level
measured during a sampling period, and Lxx are the statistical noise levels that are
exceeded xx-% of the time of the measurement. L50 is the average noise level that is
exceeded 50% of the time, 30 minutes in a 60 minute period.

NOISE STANDARDS

The City of Chandler and the County of Maricopa Noise Ordinances do not adopt a
specific noise standard limit. However, the Noise Ordinances state that no person shall
disturb the peace, quiet and comfort of the surrounding neighborhood (Section 11-10 and
P-23). Per each code, noise produced in the normal conduct of business is excluded from
the ordinance provisions.

EXISTING NOISE LEVELS

AGI conducted a site visit on December 6, 2021 to observe the project site and conduct
a short term noise survey. Ambient noise measurements were conducted at the project
site (NM1) and at the residential neighborhoods to the south (NM2), west (NM3) and north
(NM5). A noise measurement was also conducted at the commercial boundary located to
the north (NM4). Figure 3 shows the location of the noise measurement locations.

The short-term Leq measured at location NM1 was 59.1 dBA. The noise sources
contributing to the ambient measurement data at NM1 were from vehicular traffic, distant
car exhaust, small aircraft, and cars at gas station parking lot. The short-term Leq
measured at receiver NM2 was 62.2 dBA with contributing noise sources from vehicular
traffic, distant car exhaust, loud motorcycle exhaust, music and small aircraft. At receiver
NM3, the short-term Leq was 73.6 dBA and was primarily due to vehicular traffic, car
exhaust and car music and to a lesser extent distant gardeners and small aircraft. The
short-term Leq at receiver NM4 was 60.6 dBA and was attributed to vehicular traffic,
parking lot and small aircraft. The short-term Leq was 68.5 dBA at location NM5 and was
due to vehicular traffic, loud motorcycle and car exhausts, distant gardeners, and small
aircraft. Table 1 summarizes the noise measurement data from the survey. Refer to the
Appendix for the measurement data sheets.

NOISE ANALYSIS

The future noise generated from Kerry’s Auto operations has the potential to impact
nearby properties. The methodology used to analyze and predict operations noise from
the project involved the use of the CadnaA computer noise model. CadnaA can simulate
the physical environment by factoring in x, y, and z geometrics of a particular site to
simulate the buildings, obstacles, and typography. The model uses industry recognized
algorithms (ISO 9613) to perform acoustical analyses. The noise generated by future

operations was calculated by inputting acoustical sources at the project site. AGI’s
industry acoustical database was used for the modeling inputs.

Kerry’s Auto’s future operations were analyzed based on the updated northern site plan
that is located further away from residences at the southern property boundary. The
northern facing roll up door will direct operations noise to the northern direction towards
the existing commercial development and away from the southern and western residential
developments. The overall benefit of the northern site configuration is a reduced noise
exposure to the residents to the south compared to locating the building at the southern
minimum setback of the originally approved PDP.
Operational noise sources were modeled for peak hour activity where all the service bays
are all operating simultaneously. The future facility will include 8 lifts, an alignment rack,
air compressor and a standard array of pneumatic, electric and hand tools. The operator
is forecasting as much as 905 vehicles per month or 30 vehicles per day for service1.
Typical noise sources from the facility will include the compressor, brake rotor lathe,
loudspeaker public address, tire balance machine, releasing air from tires, impact wrench,
tire dismount and remount, lifts, air ratchet, lift air valve, alignment rack, hammering, cars
starting and car door slam. Table 2 lists the typical equipment and operational noise levels
from the future facility.

The hourly Leq from future facility operations is estimated to be 52 dBA at the office
boundary to the east (NM1), 46.2 dBA at the residential boundary to the south (NM2), 40
dBA at the residential boundary to the west (NM3), 41.3 dBA at the residential boundary
to the north (NM4) and 53.8 dBA at the commercial boundary to the north (NM5),
respectively. Table 3 summarizes the projected operational noise levels at the nearest
boundaries. Refer to Figure 4 for a noise contour map of Kerry’s Auto’s Projected
Operational Noise Levels. Refer to the Appendix for the projected individual equipment
noise levels at each receiver location.

IMPACT ASSESSMENT

The hourly Leq from future facility operations is estimated to be 52 dBA at receiver NM1,
46.2 dBA at receiver NM2, 40 dBA at receiver NM3, 41.3 dBA at receiver NM4 and 53.8
dBA at receiver NM5, respectively. When combined with the ambient background noise,
the increase in noise level above the ambient baseline will be 0.8 dB at NM1, 0.1 dB at
NM2, 0.0 dB at NM3, 0.1 dB at NM4 and 0.1 dB at NM5. The increase in noise level
attributed to the future operational noise levels will be less than significant and will not
result in significant noise impacts at any of the nearby boundary locations2.
Because the noise from air lifts, air ratchet, air drill, and impact wrenches are distinctive,
the operational noise levels from the future Kerry’s Auto could be occasionally audible to
the nearest receivers when there are lulls in the background traffic noise. Noise control
measures are identified to reduce operational noise levels to lessen annoyance. Refer to
Table 4 for a summary of the future Kerry’s Auto operational noise levels and impact
assessment.

NOISE CONTROL MEASURES

The following noise control measures should be implemented to minimize noise at the
nearest residential properties:
1. Low noise power tools such as electric or low noise equivalent, should be used.
2. Rotary electric lifts should be used in lieu of pneumatic lifts.
3. Noisy equipment such as the brake lathe should be located within the service area
and shielded from line of site to the nearest homes to the north.
4. The air compressor should be shielded with a minimum 6-ft high concrete masonry
unit (CMU) walled enclosure with a solid rooftop constructed from minimum 5/8” thick
tongue and groove plywood with built-up roofing. The access door should be a solid
core wood or metal panel door to form a continuous barrier to prevent sound
transmission.
5. The metal roll up door should be kept closed during the early morning and evening
hours to the extent feasible.

CONCLUSION

AGI has conducted a noise study of the Kerry’s Auto Project in Chandler, AZ. The Kerry’s
Auto’s Site Plan has been reviewed, noise measurements conducted, noise levels
analyzed, and an impact assessment performed to determine compliance with the City of
Chandler Noise Ordinance.
