1.2 Fundamentals of Noise
Sound levels are described in units called the decibel (dB). Decibels are measured on a logarithmic scale that quantifies sound intensity in a manner similar to the Richter scale used for earthquake magnitudes. Thus, a doubling of the energy of a noise source, such as doubling of traffic volume, would increase the noise level by 3 dB; a halving of the energy would result in a 3 dB decrease.

Additionally, in technical terms, sound levels are described as either a "sound power level" or a "sound pressure level," which while commonly confused are two distinct characteristics of sound. Both share the same unit of measure, the dB. However, sound power, expressed as Low, is the energy converted into sound by the source. The Low is used to estimate how far a noise will travel and to predict the sound levels at various distances from the source. As sound energy travels through the air, it creates a sound wave that exerts pressure on receivers such as an eardrum or microphone and is the sound pressure level. Noise measurement instruments only measure sound pressure, and noise level limits used in standards are generally sound pressure levels.

The human ear is not equally sensitive to all frequencies within the sound spectrum. To accommodate this phenomenon, the A-scale, which approximates the frequency response of the average young ear when listening to most ordinary everyday sounds, was devised. When people make relative judgments of the loudness or annoyance of a sound, their judgments correlate well with the A-scale sound levels of those sounds. Therefore, the "A-weighted" noise scale is used for measurements and standards involving the human perception of noise. Noise levels using A-weighted measurements are designated with the notation dB(A). The impact of noise is not a function of loudness alone. The time of day when noise occurs and the duration of the noise are also important. In addition, most noise that lasts for more than a few seconds is variable in its intensity. Consequently, a variety of noise descriptors has been developed. The noise descriptors used for this study are the one-hour equivalent noise level (Leg), the community noise equivalent level (CNEL), and the day night equivalent level (Lon). The CNEL is a 24-hour equivalent sound level.

The CNEL calculation applies an additional 5 dB(A) penalty to noise occurring during evening hours, between 7:00 p.m. and 10:00 p.m., and an additional 10 dB(A) penalty is added to noise occurring during the night, between 10:00 p.m. and 7:00 a.m. These increases for certain times are intended to account for the added sensitivity of humans to noise during the evening and night. Similar to the CNEL, the Lon is a 24-hour equivalent level that applies an additional 10 dB(A) penalty to noise occurring during the night.

Sound from a small, localized source (approximating a "point" source) radiates uniformly outward as it travels away from the source in a spherical pattern, known as geometric spreading. The sound level decreases or drops off at a rate of 6 dB(A) for each doubling of the distance.

Traffic noise is not a single, stationary point source of sound. The movement of vehicles makes the source of the sound appear to emanate from a line (line source) rather than a point when viewed over some time interval. The drop-off rate for a line source is 3 dB(A) for each doubling of distance.

The propagation of noise is also affected by the intervening ground, known as ground absorption. A hard site (such as parking lots or smooth bodies of water) receives no additional ground attenuation, and the changes in noise levels with distance (drop-off rate) are simply the geometric spreading of the source. A soft site (such as soft dirt, grass, or scattered bushes and trees) receives an additional ground attenuation value of 1.5 dB(A) per doubling of distance.

Thus, a point source over a soft site would attenuate at 7.5 dB(A) per doubling of distance.

Human perception of noise has no simple correlation with acoustical energy. A change in noise levels is generally perceived as follows: 3 dB(A) barely perceptible, 5 dB(A) readily perceptible, and 10 dB(A) perceived as a doubling or halving of noise (California Department of Transportation [Caltrans] 2013).

2.0 Applicable Standards

2.1 General Plan
The Noise Element of the General Plan establishes noise compatibility standards for a variety of land uses. For the purposes of this analysis, the noise standards for schools, churches, and libraries were used to assess compatibility.

For these land uses, noise levels are considered clearly acceptable up to 55 CNEL and normally acceptable up to 60 CNEL.

2.2 Municipal Code
Title 41 of the CMC contains the City's Noise Abatement and Control Regulations. Noise level limits for operational noise sources are provided in Section 41.10.010 and construction noise regulations are provided in Sections 4.10.040 and 4.10.050.

2.2.1 Municipal Code Operational Noise Regulations
The applicable property line noise level limits provided in Section 41.10.010 of the CMC are summarized in Table 1.

These maximum one-hour sound level limits are the maximum noise levels allowed at any point on or beyond the property boundaries due to activities occurring on the property. Where two or more zones adjoin, the sound level limit is the arithmetic mean of the respective limits for the two zones.

Table 1

The project site is zoned R-3/P. The property to the northeast is zoned R-3/P, the properties to the southeast are zoned R-3, and the properties to the south, west, and north are zoned C. Therefore, the applicable property line limits between the project site and the adjacent residential uses are 55 dB(A) Leg during the daytime, 50 dB(A) Leg in the evening, and 45 dB(A) Leg during the nighttime, and the applicable property line limits between the project site and the adjacent commercial uses are 57.5 dB(A) Leq during the daytime, 55 dB(A) Leq in the evening, and 47.5 dB(A) Lea during the nighttime.

2.2.2 Municipal Code Construction Noise Regulations
The following is from CMC Noise Abatement and Control Regulations:

41.10.040 Construction noise curfew.

A. It shall be unlawful for any person, between the hours of 7:00 p.m. and 7:00 a.m. of any day or on legal holidays and Sundays to erect, construct, demolish, excavate for, alter or repair any building or structure in such a manner as to create a disturbing, excessive or offensive noise unless a noise control permit has been applied for and granted beforehand by the Noise Control Officer. In granting such a permit, the Noise Control Officer should consider whether the construction noise in the vicinity of the proposed work site would be less objectionable at night than during the daytime; whether obstruction and interference with traffic, particularly on streets of major importance, would be less objectionable at night than during the daytime; whether the type of work to be performed emits noises at such a low level as to not cause significant disturbances in the vicinity of the work site; the character and nature of the neighborhood of the proposed work site; whether great economic hardship would occur; if the work is in the general public interest; and he shall prescribe such conditions, working time, types of construction equipment to be used and permissible noise levels as he deems to be required in the public interest.

B. The provisions of subsection A of this section shall not apply to emergency work as defined herein; provided, that the Noise Control Officer shall be notified in writing of such emergency work no later than 48 hours after work commences.

41.10.050 Construction noise limits.

Except as provided in CMC 41.10.040(B), it shall be unlawful for any person, including the City of Coronado, to conduct any construction activity so as to cause, at or within the property lines of any property zoned residential, an average sound level greater than 75 decibels during a one-hour period any time between the hours of 7:00 a.m. to 7:00 p.m. unless a variance has been applied for and granted by the Noise Control Officer.

3.0 Existing Conditions
Existing noise levels in the vicinity of the project site were measured on May 19, 2024, using one Larson-Davis Model LxT, Type 1 Integrating Sound Level Meter, serial number 3829. The following parameters were used:

Filter: A-weighted
Response: Slow
Interval Period 1 minute
Time History Period: 5 seconds
The meter was calibrated before measurement. The meter was set 5 feet above the ground level for each measurement. The weather was cloudy and cool with a slight breeze during the measurement period. Figure 4 shows the noise measurement locations. Noise measurement data is provided in Attachment 1.

Measurement 1 was located near the eastern project boundary approximately 25 feet from C Avenue and 60 feet from 10th Street. The main source of noise was vehicle traffic on C Avenue and 10th Street, and secondary sources of noise included pedestrians. Noise levels were measured for 15 minutes, and vehicle traffic on C Avenue was counted.

The average measured noise level was 56.1 dB(A) Leq.

Measurement 2 was located near the southern project boundary approximately 30 feet from the centerline of 10t Street and 10 feet from the existing building on-site. The main source of noise was vehicle traffic on 10th Street, and secondary sources of noise included bells and activities at the adjacent church. Noise levels were measured for 15 minutes, and vehicle traffic on 10th Street was counted. The average measured noise level was 60.6 dB(A) Leq.

Measurement 3 was located at the western project boundary adjacent to the alley and approximately 105 feet from 10th Street. The main sources of noise included vehicle traffic on 10th Street and through the alley, a delivery truck in the alley, and activities at the adjacent commercial uses. Noise levels were measured for 15 minutes, and vehicle traffic on 10th Street and in the alley was counted. The average measured noise level was 62.6 dB(A) Lea- Table 2 summarizes the measured noise levels. Table 3 summarizes the traffic counts.

4.0 Methodology
Noise level predictions and contour mapping were developed using noise modeling software, SoundPlan Essential, version 4.1 (Navcon Engineering 2018). SoundPLAN calculates noise propagation based on the International Organization for Standardization method (ISO 9613-2 - Acoustics, Attenuation of Sound during Propagation Outdoors). The model calculates noise levels at selected receiver locations using input parameter estimates such as total noise generated by each noise source; distances between sources, barriers, and receivers; and shielding provided by intervening terrain, barriers, and structures. The model outputs can be developed as noise level contour maps or noise levels at specific receivers. In all cases, receivers were modeled at 5 feet above ground elevation, which represents the average height of the human ear.

4.1 Construction Noise Analysis
Project construction noise would be generated by diesel engine-driven construction equipment used for site preparation and grading, building construction, loading, unloading, and placing materials and paving. Diesel engine-driven trucks also would bring materials to the site and remove the soils from excavation.

Construction equipment with a diesel engine typically generates maximum noise levels from 70 to 95 dB(A) Leq at a distance of 50 feet (Federal Highway Administration [FHWA] 2006 and 2008; Federal Transit Authority 2018). During construction, equipment moves to different locations and goes through varying load cycles, and there are breaks for the operators and for non-equipment tasks, such as measurement. Table 4 summarizes typical construction equipment noise levels and duty cycles.

The project site is surrounded by multi-family residential uses to the northeast, a church and preschool to the east and southeast, and commercial properties to the south, southwest, and northwest. Construction noise levels were modeled at the adjacent receivers assuming the simultaneous use of an excavator and a loader, which would generate a combined sound power level of 113.9 dB(A) Low. This noise level was modeled as an area source covering the entire project site. The existing wall located between the project site and the property to the north was taken into account.

Additionally, there is a possibility that site dewatering would be required if groundwater is encountered during excavation. Dewatering would require the use of a 5 horsepower pump that would operate continuously including during the nighttime hours. Based on calculation details provided in An Introduction to Sound Level Data for Mechanical and Electrical Equipment (Continuing Education and Development, Inc. 2013), a 5 horsepower pump with - 30 to no fitical guipment (Continuing Education and a 3,000 to 3,600 rotations per minute motor generates a noise level of 76.0 dB(A) Leg at 3 feet which is equivalent to a sound power level of 83.2 dB(A) Lpw. This noise level was modeled as a point source near the center of the project site. Pump specifications are provided in Attachment 2.

4.2 Traffic Noise Analysis

4.2.1 On-Site Noise Compatibility
The SoundPLAN program uses the FHWA Traffic Noise Model algorithms and reference levels to calculate traffic noise levels at selected receiver locations. The model uses various input parameters, such as projected hourly average traffic rates; vehicle mix, distribution, and speed; roadway lengths and gradients; distances between sources, barriers, and receivers; and shielding provided by intervening terrain, barriers, and structures. Receivers, roadways, and barriers were input into the model using three-dimensional coordinates.

The main source of traffic noise at the project site is vehicle traffic on 10th Street, C Avenue, and Orange Avenue. Year 2025 and year 2050 traffic volumes were obtained from San Diego Association of Governments (SANDAG) Series 14 traffic projections (SANDAG 2024). The year 2025 vehicle traffic volumes were used to determine if the project would result in a significant increase in ambient noise levels. Because the year 2025 traffic volumes are greater than year 2050 volumes, year 2025 vehicle traffic volumes were used to determine compatibility with the City's noise standards.

There are no traffic projections available for the segments of 10th Street and C Avenue immediately adjacent to the project site because they do not carry large traffic volumes. However, the portion of 10th Street northwest of the project site has a year 2025 volume of 1,400 average daily traffic (ADT). As a conservative analysis, this volume was used to calculate traffic noise levels due to the segments of 10th Street and C Avenue immediately adjacent to the project site. A vehicle classification mix of 95 percent automobiles, 2 percent medium trucks, 1 percent heavy trucks, 1 percent buses, and 1 percent motorcycles was modeled. Based on field traffic counts conducted during the noise Attachment 1
Mr. Jon Becker

July 23, 2024
measurements, this vehicle classification mix is conservative. Modeled noise contours take into account shielding provided by existing surrounding buildings and the proposed building. Table 5 summarizes the modeled future vehicle traffic parameters.

ADT = average daily traffic; mph = miles per hour

4.2.2 Off-Site Traffic Noise Increase
The project was also evaluated to determine if project-generated traffic would result in a significant increase in ambient noise levels. Off-site traffic noise was modeled using the FHWA Traffic Noise Prediction Model algorithms and reference levels. Traffic noise levels were calculated at 50 feet from the centerline of the affected roadways to determine the noise level increase associated with the project. The model uses various input parameters, such as traffic volumes, vehicle mix, distribution, and speed. Based on the Vehicle Miles Traveled Assessment prepared for the project, during regular operations the project would generate up to 48 ADT, and during special events the project would generate up to a maximum of 104 ADT (Linscott, Law & Greenspan, Engineers [LLG] 2024). Noise levels adjacent to Orange Avenue, 10th Street, and C Avenue were calculated using the FHWA Traffic Noise Prediction Model algorithms without and with project-generated traffic.

4.3 On-Site Noise Analysis
The operational noise sources on the project site are anticipated to be those that would be typical of religious facility, and would include rooftop mechanical equipment, people gathering, amplified music within the Assembly Hall during wedding receptions, vehicles arriving and leaving, and landscaping equipment. Noise associated with landscaping equipment is anticipated to be similar to the existing landscaping activities on the project site and typical of landscaping activities throughout the City, and would not generate noise levels in excess of CMC limits. Parking activities would occur within the underground parking garage which would be accessed from the alley to the west away from adjacent residential uses. As such, noise levels from underground parking activities would not be audible at the adjacent residential uses and are not anticipated to exceed the CMC noise level limits. This analysis therefore focuses on noise levels generated by rooftop mechanical equipment, people gathering in outdoor spaces, and amplified music. Noise levels were calculated for the following scenarios: (1) wedding/reception with maximum occupancy and amplified music, (2) larger events with maximum occupancy and no amplified music, and (3) nighttime operation of the rooftop mechanical equipment.

Attachment 1
Mr. Jon Becker

July 23, 2024
As discussed in Section 1.1, amplified music could be played during wedding receptions. The amplified music would be located inside the Assembly Hall and would end at 10:00 p.m. Based on noise level measurements conducted at a wedding, a 100-person event with amplified music and speech generates a noise level of 72.0 dB(A) Leq at 50 feet (Bollard Acoustical Consultants, Inc. 2019). This is equivalent to a sound power level of 103.6 dB(A) Low. As a condition of project approval, it would be required that all doors and windows in the Assembly Hall remain closed during events with amplified music. A 10 dB(A) noise reduction would be achieved by closing windows and doors (FHWA 2011), therefore, a noise level of 93.6 dB(A) Lpw was modeled. Amplified music was modeled during the daytime and evening hours, and would not occur during the nighttime hours after 10:00 p.m.

The project includes an outdoor terrace outside of the Assembly Hall where people could gather. Based on SoundPLAN emissions data, a normal speaking voice generates a sound power level of 65 dB(A) Lpw (Navcon Engineering 2018). A total of 25 people were modeled at the outdoor terrace, for a total sound power level of

79.0 dB(A) Lpw. This is conservative since it assumes all people would be speaking at the same time. This noise level was modeled during the daytime and evening hours since all regularly scheduled events and special events would end by 10:00 p.m.

The rooftop mechanical equipment would consist of three air conditioning units and a boiler concealed by a 42-inch parapet wall. Each of the air conditioning units were assumed to be similar to a Carrier 12.5-ton rooftop unit that generates a sound power level of 79.0 dB(A) Leq and the boiler was assumed to be similar to a 150 horsepower unit that generates a sound power level of 90.2 dB(A) Leq. Sound specifications are provided in Attachment 3. The rooftop mechanical equipment was modeled at full capacity during the daytime, evening, and nighttime hours for all three modeled scenarios.

5.0 Noise Impacts

5.1 Construction Noise Analysis
The project site is surrounded by multi-family residential uses to the northeast, a church and preschool to the east and southeast, and commercial properties to the south, southwest, and northwest. Construction noise is regulated by Sections 41.10.040 and 41.10.050 of the CMC. Construction noise shall not exceed an average hourly noise level of 75 dB(A) Leg at any residential property line. Using the parameters discussed in Section 4.1, construction noise levels were modeled at a series of 14 receivers located at the adjacent properties. The results are summarized in Table 6 Modeled receiver locations and construction noise contours are shown in Figure 5. SoundPLAN data is presented in Attachment 4.

R/3 = Multiple Family Residential, 28 dwelling units per acre, 3,500 square feet minimum lot size As shown, construction noise levels are anticipated to be 75 dB(A) Leg or less at all residentially zoned properties.

Although the existing adjacent uses would be exposed to construction noise levels that could be heard above ambient conditions, the exposure would be temporary. In accordance with Section 41.10.040 of the CMC, construction activities would not occur before 7:00 a.m. or after 7:00 p.m. on Mondays through Saturdays and would not occur any time on Sundays and holidays. As construction activities associated with the project would comply with requirements of the CMC, temporary increases in noise levels from construction activities would be less than significant. Note that modeled construction noise levels take into account the existing wall located between the project site and the residential uses to the north. In order to comply with the noise level limits of the CMC, it shall be required that this wall remain in place during all project construction activities.

Although construction noise levels are not anticipated to exceed 75 dB(A) Leg, due to the proximity of the adjacent residential uses, the following measures are recommended to ensure that the project complies with the CMC.

NOS-1 The City shall ensure that the construction contractor(s) contract and specifications for all project-related activities include the following requirements during construction activities:
• The existing wall located between the project site and the residential uses to the north shall remain in place during all project construction activities.
• Construction hours shall be conducted in compliance with Coronado Municipal Code (CMC) 41.10.040 with respect to allowable timeframes and days of the week (including weekends and holidays). Per CMC 41.10.050, noise from construction activities shall meet the standard of 75 dB(A) Leg over any one- hour period, unless authorization to exceed this limit has been granted via permit by the City's Noise Control Officer (NCO) in advance.

• Construction during nighttime hours is prohibited unless authorized by the NCO in advance via permit. • All idling (i.e., engines running) equipment shall be kept to a minimum. • The use of noise-producing signals, including horns, whistles, alarms, and bells, shall be used for safety warning purposes only.
• Communication with local residents shall be maintained prior to and during construction. Specifically, the local residents shall be informed of the schedule, duration, and progress of the construction and shall be provided contact information (e.g., a telephone hotline and/or email address) for noise- or vibration-related complaints. The City shall establish a process to investigate these complaints in a timely manner and, if determined to be valid, detail efforts to provide a timely resolution and response to the complainant—with copy of outcome description documented in a log for the duration of the construction activities.
• Locate fixed/stationary equipment (e.g., generators, compressors) shall be located as far as possible from residential uses.
• All noise-producing equipment and vehicles using internal combustion engines shall be equipped with exhaust mufflers (or comparable noise-reducing exhaust flow treatments); air-inlet silencers; and, hoods, shrouds, shields, or other noise-reducing features in good operating condition that meet or exceed original factory specifications. Mobile or fixed "package" equipment (e.g., arc-welders, air compressors, generators) shall be equipped with shrouds and noise control features that are readily available for that type of equipment.

Additionally, as discussed in Section 4.1, there is a possibility that site dewatering would be required with the use of a pump that would operate continuously including during the nighttime hours. Since pump operation would occur outside the times allowable by Section 41.10.040 of the CMC, the applicable noise level limits would be those provided in Section 41.10.010 of the CMC (see Table 1). These limits include 45 dB(A) Leg at the residentially zoned properties and 47.5 dB(A) Leg at the commercially zoned properties. Pump noise levels were modeled using the parameters discussed in Section 4.1. The results are summarized in Table 7. Modeled receiver locations and dewatering noise contours are shown in Figure 6. SoundPLAN data is presented in Attachment 5.

The following considerations shall be implemented as necessary to ensure that noise levels due not exceed the applicable CMC limits:
• The noise specifications for the selected pump shall not exceed a sound pressure level of 76.0 dB(A) Leg at 3 feet.
• The pump shall be located as far away from the residentially zoned properties as feasible, and shall not be located closer than 50 feet from the residentially zoned properties. • An enclosure or barrier shall be constructed around the pump in order to shield noise from the adjacent residentially zoned properties.
• Communication between the applicant team and local residents shall be maintained prior to and during construction, including all dewatering activities. Specifically, the local residents shall be Attachment 1

5.2 Traffic Noise Analysis

5.2.1 On-site Noise Compatibility
Noise and land use compatibility is regulated by the Noise Element of the City's General Plan. Noise levels for the project are considered clearly acceptable up to 55 CNEL and normally acceptable up to 60 CNEL. In normally acceptable areas, common building construction would make the indoor noise environment acceptable.

Vehicle traffic noise level contours across the project site were calculated using SoundPLAN. These contours take into account the project area topography and shielding provided by existing surrounding buildings and the proposed building. Noise levels were also modeled at a series of 12 specific receiver locations on the project site. These receivers and noise contours are shown in Figure 7. The results are summarized in Table 8. SoundPLAN data are provided in Attachment 6.

Mr. Jon Becker

July 23, 2024
The interior noise level standard for noise sensitive land uses is 45 CNEL. Interior noise levels can be reduced through standard construction techniques. When windows are closed, standard construction techniques provide various exterior-to-interior noise level reductions depending on the type of structure and window. According to the FHWA's Highway Traffic Noise Analysis and Abatement Guidance, buildings with masonry façades and double-glazed windows can be estimated to provide a noise level reduction of 35 dB, while light-frame structures with standard windows may provide noise level reductions of at least 20 dB (FHWA 2011). Because exterior noise levels are projected to be 60 CNEL or less, assuming a 20 dB exterior-to-interior noise reduction would result in interior noise levels that are 40 CNEL or less. Thus, interior noise levels would not exceed the standard of 45 CNEL. Exterior and interior noise impacts would be less than significant.

5.2.2 Off-Site Vehicle Traffic Noise
The project would contribute traffic to the local roadways. However, the project would not substantially alter the vehicle classifications mix on local or regional roadways nor would the project alter the speed on an existing roadway or create a new roadway. Thus, the primary factor affecting off-site noise levels would be increased traffic volumes.

While changes in noise levels would occur along any roadway where project-related traffic occurs, for noise assessment purposes, noise level increases are assumed to be greatest nearest the project site, as this location would represent the greatest concentration of project-related traffic. A substantial noise increase is defined as an increase of 3 dB above existing conditions.

As discussed in Section 2.2.2, during regular operations the project would generate up to 48 ADT, and during special events the project would generate up to a maximum of 104 ADT (LLG 2024). Table 9 summarizes the traffic noise levels without and with the project and the associated increase in noise. FHWA calculations are shown in Attachment 7.

NOTE: Noise levels are modeled at 50 feet from the roadway.

CNEL = community noise equivalent level
As shown, the project would result in a noise increase of 0.3 dB or less, which would not be an audible change in noise levels. Therefore, the project would not result in the exposure of noise sensitive land uses to significant noise levels, and impacts would be less than significant.

5.3 On-Site Noise Analysis
The operational noise sources on the project site are anticipated to include rooftop mechanical equipment, people gathering, and amplified music within the Assembly Hall during wedding receptions. Noise level limits for operational Attachment 1
Mr. Jon Becker

noise sources are provided in Section 41.10.010 of the CMC. Using the parameters discussed in Section 4.3, property line noise levels were modeled using SoundPLAN. Noise levels were calculated for the following scenarios:
(1) wedding/reception with maximum occupancy and amplified music, (2) larger events with maximum occupancy and no amplified music, and (3) nighttime operation of the rooftop mechanical equipment. The modeling results are summarized in Table 10. Operational noise contours are shown in Figures 8a through 8c. SoundPLAN data is contained in Attachment 8.

The noise sources modeled for the first scenario, special event with amplified music, includes indoor amplified music and speech, people gathering on the outdoor terrace, and rooftop mechanical equipment. The noise sources modeled for the second scenario, event without amplified music, include people gathering on the outdoor terrace and rooftop mechanical equipment As shown in Table 10, noise levels due to these on-site noise sources would not exceed either the daytime or evening noise level limits. All events would end at 10:00 p.m. Therefore, the only remaining on-site noise source during the nighttime hours would be the rooftop mechanical equipment. As shown, noise levels due to this equipment would be less than the applicable nighttime noise level limit. Project operation would comply with the CMC and impacts would be less than significant. As a condition of project approval, it would be required that all doors and windows in the Assembly Hall remain closed during events with amplified music.

NOS-3 The project's Major Special Use Permit shall include the following conditions:
• Noise levels shall not exceed the applicable noise level limits specified in the CMC. The applicable noise level limits between the project site and the adjacent R-3 and R-3/P zones are 55 dB(A) Lea between 7:00 a.m. and 7:00 p.m., 50 dB(A) Leq between 7:00 p.m. and 10:00 p.m., and 45 dB(A) Lea between 10:00 p.m. and 7:00 a.m. The applicable noise level limits between the project site and the adjacent C zones are 57.5 dB(A) Leq between 7:00 a.m. and 7:00 p.m., 55 dB(A) Leq between 7:00 p.m. and 10:00 p.m., and 47.5 dB(A) Leq between 10:00 p.m. and 7:00 a.m. • During all events with amplified music, all facility windows and doors shall remain closed. • Amplified music shall not exceed a noise level of 72 dB(A) Leq when measured at 50 feet from the speakers.

5.4 Vibration
Human reaction to vibration is dependent on the environment the receiver is in, as well as individual sensitivity. For example, outdoor vibration is rarely noticeable and generally not considered annoying. Typically, humans must be inside a structure for vibrations to become noticeable and/or annoying (FTA 2018). Based on several federal studies, the threshold of perception is 0.035 inch per second (in/sec) peak particle velocity (PPV), with 0.24 in/sec PPV being a distinctly perceptible (Caltrans 2013). Vibration perception would occur at structures, as people do not perceive vibrations without vibrating structures (FTA 2018).

Construction activities produce varying degrees of ground vibration depending on the equipment and methods employed. Ground vibrations from typical construction activities rarely reach levels high enough to cause damage to structures. Based on best available data, impacts associated with project construction equipment vibration shall be considered significant if the PPV exceeds 0.2 in/sec which is the standard recommended by the FTA for assessing construction vibration impacts at masonry structures such as those surrounding the project site (FTA 2018).

Table 11 summarizes the vibration levels generated by equipment that could be used at the project site.

Table 11
Construction Equipment Vibration Levels
Equipment PPV (in/sec) at 25 feet) Distance to 0.2 PPV (feet) Small Bulldozer 0.003 <1
Loaded Truck 0.076 10
Jackhammer 0.035 5
SOURCE: FTA 2018.

PPV = peak particle velocity; in/sec = inch per second
Attachment 1
Mr. Jon Becker

July 23, 2024
Construction equipment with the greatest potential to generate vibration would be a loaded truck. According to the FTA, loaded trucks generate vibration levels of 0.089 in/sec PPV at 25 feet. Vibration levels would exceed 0.2 in/sec PPV at distances closer than 10 feet between the equipment and a building. The nearest building is located approximately 10 feet from the edge of the project footprint. A loaded truck would not be located immediately adjacent to the building due to physical constraints. Rather, they would be located either on the adjacent roads or on the project site at distances greater than 10 feet from the adjacent buildings. All other construction equipment operating on-site would generate vibration levels that are less than a loaded truck. Further, all construction activities would occur during the daytime hours between 7:00 a.m. and 7:00 p.m. as required by the CMC Noise Abatement and Control Regulations and would not generate any vibration during the night when it would be more likely to create a disturbance. Therefore, project construction is not anticipated to generate significant vibration levels. Once operational, the project would not be a source of groundborne vibration.

6.0 Conclusions
Noise impacts due to construction and operation of the project were assessed in accordance with standards established in the City's General Plan Noise Element and the CMC. As discussed in this analysis, construction noise levels are anticipated to be 75 dB(A) Leq or less at the adjacent properties. Although the existing adjacent uses would be exposed to construction noise levels that could be heard above ambient conditions, the exposure would be temporary. Due to the proximity of the adjacent residential uses, in order to ensure that construction activities associated with the project comply with requirements of the CMC, mitigation measure NOS-1 would be required.

With implementation of mitigation measure NOS-1, temporary increases in noise levels from construction activities would be less than significant.

The project may also require dewatering if groundwater is encountered. Since pump operation would occur outside the times allowable by Section 41.10.040 of the CMC, the applicable noise level limits would be those provided in Section 41.10.010 of the CMC. Pump noise levels are not anticipated to exceed the applicable noise level limits at the adjacent properties. Due to the proximity of the adjacent residential uses and the fact that the pump would need to operate during the nighttime hours, mitigation measure NOS-2 would be required. With implementation of mitigation measure NOS-2, temporary increases in noise levels from dewatering activities would be less than significant.

Future exterior noise levels are projected to be less than 60 CNEL at the proposed church, and are considered normally acceptable. Thus, the project could be compatible with City standards. Because exterior noise levels are projected to be 60 CNEL or less, assuming a 20 dB exterior-to-interior noise reduction would result in interior noise levels that are 40 CNEL or less. Thus, interior noise levels would not exceed the standard of 45 CNEL. Exterior and interior noise impacts would be less than significant.

The project would contribute traffic to the local roadways. As calculated in this analysis, the project would result in a noise increase of 0.3 dB or less, which would not be an audible change in noise levels. Therefore, the project would not result in the exposure of noise sensitive land uses to significant noise levels, and impacts would be less than significant.

Property line noise levels due to on-site events with amplified music, events without amplified music, and rooftop mechanical equipment are not anticipated to exceed the applicable limits specified in the CMC. In order to ensure that project operation would comply with requirements of the CMC, mitigation measure NOS-2 would be required.

With implementation of mitigation measure NOS-3, impacts due to on-site noise sources would be less than significant.

Sound Level
Table A2-20 summarizes predicted sound pressure levels for Model CB Boilers. Tables A2-21 through A2-25 give detailed octave band sound pressure levels for each boiler. These values are based on standard motors. Optional motor types and alti- tude conditions can increase sound levels.

Units
The units for the sound level tables are dBA (decibels, mea- sured on the A-weighted scale) in reference to 0.0002
microbars (20 micro-Newtons per square meter). They are standardly referenced in specifying and reporting sound pres- sure levels on industrial equipment.

Test Method
The sound pressure levels in the above tables were obtained from tests in accordance with the "ABMA Test Code for the Measurement of Sound from Packages Boilers." In accordance with this code, the sound pressure levels reported were mea- sured on the boiler centerline 4-1/2 feet vertically above the bottom of the base rails and 3 feet horizontally in front of the end of the blower motor or front surface of the electrical cabi- Sound Level Meter
The sound level meter used complies with ANSI S1.4, Type 1 (Precision). The readings are taken with the meter set for slow response.

Sound Pressure sound levels. (Since A-scale sound levels are dominated by mid-frequency sounds, the A-scale sound levels between two On large size boilers, the need for auxiliary equipment, and the boilers can be in reasonable agreement even though the low necessary interconnecting piping, make it impractical (and and high frequencies of octave band measurement do not
sometimes impossible) to provide a boiler testing environment closely correspond). that is suitable for obtaining the data needed to develop Sound Pressure Power levels.

Typical Values
Sound pressure levels (dBA) for identical boilers will vary between boiler rooms. In addition, variations will occur between different people using different sound meters on the same boiler. And finally, no two boilers can be expected to give precisely the same sound levels. For these reasons, we can only predict, but not guarantee, sound levels (dBA).

Octave Band
When predicting sound pressures in octave bands (e.g., dB at 125 Hz), even greater variations between boilers, between sound meters, and between operators can be expected. These larger variations in the low and high frequencies make octave band levels a less reliable method of reporting than A-scale A2-30 Cleaver y Brooks®
