1.0 EXECUTIVE SUMMARY The proposed project, Starbucks – Pacific Coast Highway and Western Avenue, consists of the demolition of existing structures and the construction of a new walk-up and drive-through coffee shop. The project site is located at 1730-1734 Pacific Coast Highway in the Cities of Los Angeles and Lomita, California. The City of Los Angeles Department of Building and Safety, City of Lomita, and State of California require that commercial developments demonstrate compliance with the requirements of the California Green Building Standards Code (known as CALGreen). CALGreen states that, if noise level readings of 65 dBA LEQ or greater are documented at the proposed project site, the project must either (a) incorporate wall and roof/ceiling assemblies with a composite STC rating of at least 50 and exterior windows with an STC rating of at least 40, or (b) provide an acoustical analysis documenting interior noise levels do not exceed 50 dBA in occupied areas during any hour of operation. This report provides the performance method analysis described in Item (b). Calculations show that with the proposed exterior wall assembly and windows with a minimum rating of STC 25 in place, interior noise levels of 50 dBA or less can be achieved during the worst-case hour of operation (loudest ambient noise). With these project design features in place, all occupied rooms are expected to comply with CALGreen noise requirements. In addition, the Municipal Codes of the Cities of Los Angeles and Lomita require the assessment of noise impacts from the drive-through intercom system to determine if additional project design features are necessary and feasible to reduce project-related noise impacts to comply with applicable noise limits. Calculations show that, as currently designed, exterior noise levels from the proposed intercom are expected to meet the applicable nighttime noise limits defined by the Cities of Los Angeles and Lomita at all surrounding property lines. No mitigation is deemed necessary to attenuate project-generated noise impacts at neighboring receivers.

2.0 INTRODUCTION This acoustical analysis report is submitted to satisfy the noise requirements of the City of Los Angeles, the City of Lomita, and State of California. Its purpose is to assess interior noise impacts to the project site from transportation noise sources to determine if mitigation is necessary to reduce these noise impacts to comply with the applicable noise regulations of the City of Los Angeles and the California Green Building Standards Code (CALGreen). Additionally, this report assesses noise impacts from on-site project-related noise sources to determine if mitigation is necessary to reduce the noise impacts to be compliant with applicable limits. All noise level or sound level values presented herein are expressed in terms of decibels (dB), with A-weighting, abbreviated "dBA," to approximate the hearing sensitivity of humans. Time-averaged noise levels are expressed by the symbol “LEQ.” Unless a different time period is specified, “LEQ” is implied to mean a period of one hour. Some of the data may also be presented as octave-band-filtered and/or A-octave-band-filtered data, which are a series of sound spectra centered about each stated frequency, with half of the bandwidth above and half of the bandwidth below each stated frequency. This data is typically used for machinery noise analysis and barrier calculations.

2.1 Project Description

The proposed project, Starbucks – Pacific Coast Highway and Western Avenue, consists of the demolition of existing structures and the construction of a new walk-up and drive-through coffee shop. The project will include interior workspaces, storage, and restrooms, but will not contain any indoor cafe space. The drive-through intercom system is located to the south of the proposed building. The proposed hours of operation for the store are 24 hours a day. For additional project details, please refer to the project plans provided in Appendix A.

2.2 Project Location

The subject property is located at 1730-1734 Pacific Coast Highway in the Cities of Los Angeles and Lomita, California. The Assessor’s Parcel Numbers is 7553-018-084 and 7553-018-032. The site is currently occupied by two existing buildings, both of which will be demolished. For a graphical representation of the site, please refer to the Vicinity Map, Assessor’s Parcel Map, Satellite Aerial Photograph, and Topographic Map, provided as Figures 1 through 4, respectively.

2.3 Applicable Noise Regulations

The City of Los Angeles Department of Building and Safety, City of Lomita, and State of California require that commercial developments demonstrate compliance with the requirements of the California Green Building Standards Code (known as CALGreen). CALGreen states that, if noise level readings of 65 dBA LEQ or greater are documented at the proposed project site, the project must either (a) incorporate wall and roof/ceiling assemblies with a composite STC rating of at least 50 and exterior windows with an STC rating of at least 40, or (b) provide an acoustical analysis documenting interior noise levels do not exceed 50 dBA in occupied areas during any hour of operation. This report provides the performance method analysis described in Item (b).

In addition to the acoustical requirements of CALGreen, noise levels from drive-through intercom equipment must be adequately controlled at surrounding noise-sensitive receivers. Residential receivers are located to the south of the project site, across 258th Place. As the adjacent receivers are located in either the City of Los Angeles or the City of Lomita, the municipal codes of both cities should be considered to ensure noise impacts will remain in compliance with applicable noise limits.

The City of Lomita requires that noise impacts are controlled to be 65 dBA or less during the daytime hours of 7 a.m. to 9 p.m. and 55 dBA or less during the nighttime hours of 9 p.m. to 7 a.m. at residential properties. Noise impacts at commercial properties must likewise be controlled to be 75 dBA during the daytime hours and 70 dBA during the nighttime hours. As the drive-through will be operational during nighttime hours, the most restrictive noise limits of 55 dBA would apply at residential receivers and 70 dBA at commercial receivers within the City of Lomita.

The City of Los Angeles Municipal Code contains “presumed ambient noise levels” for various zones and states that where the ambient noise level is less than the presumed ambient noise level, the presumed ambient shall be considered the minimum ambient noise level. Although ambient noise monitoring was conducted on the subject property, noise levels at adjacent residential properties will be less than those measured on site, due to additional distance from the roadways and shielding provided by intervening structures. For this reason, although ambient noise levels still likely exceed the presumed ambient noise levels shown herein, the presumed ambient noise levels have been considered in this analysis. The presumed ambient noise levels for residential properties are 50 dBA between the hours of 7 a.m. and 10 p.m. and 40 dBA between the hours of 10 p.m. and 7 a.m. Commercial presumed ambient noise levels are 60 dBA and 55 dBA for

_______________________________________________________________________________


daytime and nighttime hours, respectively. The Municipal Code states that sound amplifying devices shall not cause the ambient noise level to be exceeded by more than five decibels. As the drive-through will be operational during nighttime hours, the most restrictive noise limits of 45 dBA at residential receivers and 60 dBA at commercial receivers would be applied to properties within the City of Los Angeles.

Pertinent sections of the CALGreen Code and the Municipal Codes of the Cities of Lomita and Los Angeles are provided as Appendix B.

3.0 ENVIRONMENTAL SETTING

3.1 Noise Environment

The primary noise source in the vicinity of the project site is automobile and truck traffic noise from Pacific Coast Highway and Western Avenue. No other noise sources are considered to be significant.

3.2 Measured Noise Levels

A long-term noise measurement was made beginning the morning of Thursday, November 5, 2015, and running through the morning of Friday, November 6, 2015. The purpose of this measurement was to obtain noise information for the site during the proposed hours of operation, currently expected to be 24 hours a day. The noise measurement was performed at four feet above the ground in a bush along the western property line with a direct line of sight to Pacific Coast Highway. Noise data obtained on site is shown in Table 1, and the measurement location is shown graphically in Figure 5.

Measured noise levels were observed to range from 60.7 dBA between the hours of 2 a.m. and 3 a.m. on November 6 to 69.2 dBA between 6 a.m. and 7 a.m. on November 6. These noise levels are considered to be representative of noise impacts at the proposed building, as the measurement location was in-line with the northernmost wall of the proposed building, the closest wall to Pacific Coast Highway. For this reason, the highest measured hourly noise level of 69.2 dBA will be used to evaluate peak hour noise impacts at the building, as the business will be in operation during all hours of the day. Additional information is provided in Section 5.0.

3.2 Future Noise Environment

The future noise environment in the vicinity of the project site will be primarily a result of the same ambient noise sources, as well as the noise generated by activity on the project site. The primary source of noise associated with the coffee shop will be the proposed drive-through intercom equipment.

The proposed drive-through intercom is expected to be manufactured by HME. The proposed HME Intercom System is measured to have a maximum noise level of 84 dBA at one foot from the speaker post. The system will also be equipped with an automatic volume control (AVC) system that will automatically reduce the sound level produced by the intercom as the ambient noise level decreases. It is likely that the actual noise level produced by the intercom system during hours with lower levels of business would be less than the projected 84 dBA, as the ambient noise level may be lower during these hours due to lower traffic volumes; however, the higher noise level will be modeled for a worst-case analysis. For further details on the HME intercom system, please refer to Appendix C: Manufacturer Data Sheets.

4.0 METHODOLOGY AND EQUIPMENT

4.1 Methodology

4.1.1 Exterior-to-Interior Noise Analysis

CALGreen requires nonresidential buildings to be designed in order to attenuate, control, and maintain average interior noise levels not greater than 50 dBA. Contemporary exterior building construction is expected to achieve at least 15 decibels of exterior-to-interior noise attenuation with windows opened. As a result, exterior noise levels of more than 65 dBA often result in interior conditions that fail to meet the 50 dBA requirements for occupied space.

Analysis for the interior noise levels requires consideration of:

• Number of unique assemblies in the wall (doors, window/wall mount air conditioners, slidingglass doors, and windows)

• Size, number of units, and sound transmission data for each assembly type• Length of sound impacted wall(s)• Depth of sound impacted room• Height of exterior wall of sound impacted room• Exterior noise level at wall assembly or assemblies of sound impacted room

The Composite Sound Transmission data is developed for the exterior wall(s) and the calculated noise exposure is converted to octave band sound pressure levels (SPL) for a typical traffic type noise. The reduction in room noise due to absorption is calculated and subtracted from the interior octave noise levels, and the octave band noise levels are logarithmically summed to yield the overall interior room noise level. When interior noise levels exceed 50 dBA, the noise reduction achieved by each element is reviewed to determine which changes will achieve the most cost-effective compliance. Windows are usually the first to be reviewed, followed by exterior doors, and then exterior walls.

Modeling of wall assemblies is accomplished using INSUL Version 6.4, which is a model-based computer program, developed by Marshall Day Acoustics for predicting the sound insulation of walls, floors, ceilings and windows. It is acoustically based on theoretical models that require only minimal material information that can make reasonable estimates of the sound transmission loss (TL) and STC for use in sound insulation calculations; such as the design of common party walls and multiple family floor-ceiling assemblies, etc. INSUL can be used to quickly evaluate new materials or systems or investigate the effects of changes to existing designs. It models individual materials using the simple mass law and coincidence frequency approach and can model more complex assembly partitions. It has evolved over several versions into an easy to use tool and has refined the theoretical models by continued comparison with laboratory tests to provide acceptable accuracy for a wide range of constructions. INSUL model performance comparisons with laboratory test data show that the model generally predicts the performance of a given assembly within 3 STC points.

4.1.2 Cadna Noise Modeling Software

Modeling of the outdoor noise environment is accomplished using Cadna Version 4.5, which is a model-based computer program developed by DataKustik for predicting noise impacts in a wide variety of conditions. Cadna (Computer Aided Noise Abatement) assists in the calculation,

_______________________________________________________________________________


presentation, assessment, and mitigation of noise exposure. It allows for the input of project information such as noise source data, barriers, structures, and topography to create a detailed model and uses the most up-to-date calculation standards to predict outdoor noise impacts.

4.2 Measurement Equipment

Some or all of the following equipment was used at the site to measure existing noise levels:

• Larson Davis Model 720, Type 2 Sound Level Meter, Serial # 0462, with microphone &windscreen

• Larson Davis Model CA150, Type 2 Calibrator, Serial # 0203

The sound level meter was field-calibrated immediately prior to the noise measurement and checked afterward, to ensure accuracy. All sound level measurements conducted and presented in this report, in accordance with the regulations, were made with a sound level meter that conforms to the American National Standards Institute specifications for sound level meters (ANSI S1.4). All instruments are maintained with National Bureau of Standards traceable calibration, per the manufacturers’ standards.

5.0 IMPACTS AND MITIGATION

5.1 Exterior (Building Facades)

Per the Los Angeles Department of Building and Safety, noise monitoring should be performed for commercial sites in order to determine noise levels at all potential hours of operation for use in performance method interior noise calculations. Noise monitoring was performed at the project site and is detailed in Section 3.2. As shown above, peak traffic noise impacts along the western property line, in line with the northernmost wall of the proposed building, were measured to be approximately 69.2 dBA between 6 a.m. and 7 a.m. on November 6. All other hours were observed to have lesser noise impacts. For this reason, for a worst-case analysis, the maximum measured noise level of 69.2 dBA will be used to conduct peak hour interior noise calculations to determine what project design features are necessary to maintain interior noise levels of 50 dBA or less during all hours of operation, per CALGreen requirements. For a graphical representation of the noise measurement location, please refer to Figure 5.

5.2 Interior

CALGreen requires that nonresidential structures that are exposed to greater than 65 dBA during any hour of operation must control interior noise levels to be 50 dBA or less. Contemporary exterior building construction is expected to achieve at least 15 decibels of exterior-to-interior noise attenuation with windows opened. As a result, exterior noise levels of more than 65 dBA may potentially result in interior conditions that fail to meet the 50 dBA requirements for commercial space.

An exterior-to-interior noise analysis was conducted for the building to evaluate the sound reduction properties of proposed exterior wall assembly, window, and door construction designs in the building. The roof assembly was not included in this evaluation as none of the surrounding roadway noise sources are elevated above the project site grade, and therefore, the roof will be shielded from high traffic noise levels. All occupied spaces were considered in this analysis.

_______________________________________________________________________________


The proposed exterior wall will consist of stucco on the exterior over plywood sheathing with two-inch by six-inch wood framing, R19 insulation in the cavity, and 5/8-inch thick Type X gypsum board on the interior. The assembly was calculated to have a rating of STC 48. This wall assembly will be used in interior noise calculations in the building. Additionally, windows were evaluated as STC 25 insulated glazing units. Please refer to Appendix C for more details.

Calculations have been performed using the assemblies detailed above to determine whether interior noise levels of 50 dBA or less can be achieved during the worst-case hour of operation. Please refer to Table 2, showing interior noise levels with the acoustical mitigation recommendations made herein, and refer to Appendix D for additional information.

Table 2. Worst-Case Interior Traffic Noise Levels with Acoustical Recommendations

Room Maximum Assumed

Exterior Facade Impact (dBA)

Minimum STC Rating for Exterior Windows

Interior Noise Level (dBA)

Back Bar 69.2 25 48.7

Work Room 69.2 N/A 36.9

As shown above, with the proposed exterior wall assembly and windows with a minimum rating of STC 25, interior noise levels are expected to remain below 50 dBA during the worst-case hour of operation (highest ambient noise level). As this represents the maximum noise impact in any one hour period during the day, all other hours are expected to have interior noise impacts that are less than those shown above. The rating of STC 25 for windows is easily achievable with single or dual pane glass, and safety and thermal requirements will almost certainly require windows and doors that exceed this requirement; however, the STC rating of windows should be confirmed with the manufacturer to ensure this rating will be met.

Exterior door installation should include all-around weather-tight door stop seals and an improved threshold closure system. The additional hardware will improve the doors’ overall sound reduction properties. The transmission loss (TL) of an exterior door without weather-tight seals is largely a factor of sound leakage, particularly at the bottom of the door if excessive clearance is allowed for air transfer. By equipping exterior doors with all-around weather-tight seals and an airtight threshold closure at the bottom, a loss of up to 10 STC points can be prevented.

Additionally, it is imperative to seal and caulk between the rough opening and the finished door frame for all doors by applying an acoustically resilient, non-skinning butyl caulking compound. Sealant application should be as generous as needed to ensure effective sound barrier isolation. The same recommendation applies to any other penetrations, cracks, or gaps through the assembly. The OSI Green Series and the Pecora AC-20 FTR acoustic sound sealants are products specifically designed for this purpose. For additional information on these products, please refer to Appendix E: Recommended Products.

The proposed project was analyzed for worst-case exterior traffic noise impacts. With the proposed exterior wall assembly and windows meeting a minimum rating of STC 25, all occupied rooms are expected to comply with CALGreen noise requirements.

_______________________________________________________________________________


5.3 Noise Impacts on Surrounding Properties

Noise levels of the proposed drive-through intercom were calculated using Cadna at surrounding property lines to the south (across 258th Place), east, and west. Commercial properties to the north are located at a considerable distance from drive-through equipment, and will also receive shielding from the on-site building. As the evaluated receivers represent the worst-case noise exposure, no noise receiver has been placed at commercial properties to the north. As per industry standard, the receivers were calculated at a height of five feet above grade to represent the height of an average individual’s ears above ground level. This calculation also makes conservative assumptions in that it was assumed that the intercom would be in constant operation, with no breaks between orders, while in actuality it will only operate for a fraction of an hour, thereby resulting in lower average hourly noise impacts than what have been calculated.

Results of the analysis are shown in Table 3. Noise contours showing intercom equipment noise levels and receiver locations are shown in Figure 6. Additional information can be found in Appendix G: Cadna Analysis Data and Results.

Table 3. Calculated Noise Impact Levels of Drive-Through Intercom Operation

Receiver Receiver Location Noise Limit (dBA) Drive-Through Intercom Noise Impact (dBA)

R-1 South Property Line (City of Los Angeles, Residential) 45 45.0

R-2 South Property Line (City of Lomita, Residential) 55 44.9

R-3 East Property Line (City of Los Angeles, Commercial) 60 58.9

R-4 West Property Line (City of Lomita, Commercial) 70 44.0

As shown above, as currently designed, noise levels from the proposed intercom are not expected to exceed the applicable nighttime noise limits of either the City of Lomita or the City of Los Angeles at surrounding property lines. Additionally, it should be noted that, as City of Los Angeles noise limits are dependent on the ambient noise environment, this assessment shows that even with the minimum possible noise limits in place for surrounding properties, noise levels are expected to remain in compliance with applicable regulations. For these reasons, no mitigation is deemed necessary to attenuate project-generated noise impacts at neighboring receivers.

_______________________________________________________________________________


6.0 CONCLUSION

CALGreen Code requires interior noise levels of 50 dBA or less within occupied commercial space. Calculations show that with the proposed exterior wall assembly and windows with a minimum rating of STC 25 in place, interior noise levels of 50 dBA or less can be achieved during the worst-case hour of operation (loudest ambient noise). With these project design features in place, all occupied rooms are expected to comply with CALGreen noise requirements.

In addition, the Municipal Codes of the Cities of Los Angeles and Lomita require the assessment of noise impacts from the drive-through intercom system to determine if additional project design features are necessary and feasible to reduce project-related noise impacts to comply with applicable noise limits. Calculations show that, as currently designed, exterior noise levels from the proposed intercom are expected to meet the applicable nighttime noise limits defined by the Cities of Los Angeles and Lomita at all surrounding property lines. No mitigation is deemed necessary to attenuate project-generated noise impacts at neighboring receivers.

7.0 CERTIFICATION

All recommendations for noise control are based on the best information available at the time our consulting services are provided. However, as there are many factors involved in sound transmission, and Eilar Associates has no control over the construction, workmanship or materials, Eilar Associates is specifically not liable for final results of any recommendations or implementation of the recommendations.

This report is based on the related project information received and measured noise levels, and represents a true and factual analysis of the acoustical impact issues associated with Starbucks – Pacific Coast Highway and Western, to be located at 1730-1734 Pacific Coast Highway in the Cities of Los Angeles and Lomita, California.

Manufacturer Data Sheets

Memo Re: Drive-Thru Sound Pressure Levels From the Menu Board or Speaker Post The sound pressure levels from the menu board or speaker post are as follows:

1. Sound pressure level (SPL) contours (A weighted) were measured on a typical HME SPP2 speaker post. The test condition was for pink noise set to 84 dBA at 1 foot in front of the speaker. All measurements were conducted outside with the speaker post placed 8 feet from a non-absorbing building wall and at an oblique angle to the wall. These measurements should not be construed to guarantee performance with any particular speaker post in any particular environment. They are typical results obtained under the conditions described above.

2. The SPL levels are presented for different distances from the speaker post:

Distance from the Speaker (Feet) SPL (dBA)

1 foot 84 dBA 2 feet 78 dBA 4 feet 72 dBA 8 feet 66 dBA

16 feet 60 dBA 32 feet 54 dBA

3. The above levels are based on factory recommended operating levels, which are preset for

HME components and represent the optimum level for drive-thru operations in the majority of the installations.

Also, HME incorporates automatic volume control (AVC) into many of our Systems. AVC will adjust the outbound volume based on the outdoor, ambient noise level. When ambient noise levels naturally decrease at night, AVC will reduce the outbound volume on the system. See below for example:

Distance from Outside Speaker Decibel Level of standard

system with 45 dB of outside noise without AVC

Decibel level of standard system with 45 dB of outside noise with

AVC active 1 foot 84 dBA 60 dBA 2 feet 78 dBA 54 dBA 4 feet 72 dBA 48 dBA 8 feet 66 dBA 42 dBA

16 feet 60 dBA 36 dBA If there are any further questions regarding this issue please contact HME customer service at 1-800-848-4468. Thank you for your interest in HME’s products.
