II noise level or sound level values presented herein arc expressed in terms of decibels (dB), with A-weighting, abbreviated "dHJ\," to approximate the hearing sensitivity of humans. T ime-averaged noise levels arc expressed by the symbol "LEQ·" nless 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 -octave-band-filtered data, which arc 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. '11,is data is typically used for machinery noise analysis and barrier calculations. Sound pressure is the actual noise experienced by a human or registered by a sound level instrument. When sound pressure is used to describe a noise source, the distance from the noise source must be specified in order to provide complete information. Sound power, on the other hand, is a specialized analytical metric used to provide information witl,out the distance reyuircment, and may be used to calculate the sound pressure at any desired distance. 2.1 Project Description The proposed project, BM\X' of Carlsbad, includes tenant improvements to existing properties. The tenant improvements consist of tl1e remodel of a collision center, smog center, and rental car center. The collision center is proposed to have nine programming and detailing bays to provide body shop, painting, and detailing service s in addition to nine service bays to provide mechanical servicing. The smog center is proposed to have eight service bays, where smog checks/mechanical repairs will be performed. It is assumed that all buildings will include rooftop I IV AC units. The detailing/programming and service bays the primary focus of this analysis; however rooftop I IVAC equipment was also analyzed. The proposed hours of operation arc 8:30 a.m. to 9 p.m. Monday through Saturday and 10 a.m. to 7 p.m. on Sunday. For addi tional project details and equipment positioning, please refer to tl1e project plans provided in Appendix A. Eilar Associates, Inc. 2.2 Project Location The subj ect properties are located at 5215 Car County Drive and 5245 Car County Drive in the City of Carlsbad, California. The 5215 Car County Drive site is currently occupied by a car dealership, and will be renovated to contain a collision center. The 5245 Car County Drive site is currently occupied by a smog center and car rental center, proposed to remain. The Assessor's Parcel umbers (AP s) for the sites are 21 l-080-12-00 and 211- 080-13-00. For a graphical representation of the site, please refer to the Vicinity Map, Assessor's Parcel Map, Satellite Aerial Photograph, and T opographic Map provided as Figures 1 through 4, respectively. 2.3 Applicable Noise Regulations The City of Carlsbad oise Elemen t to the G eneral Plan provides noise standards for non-tran sportation noise sources such as service bays and HVAC equipment. As measured from the property Linc of noise-sensitive receivers, non-transportation no ise sources must not exceed 55 dB L EQ between the ho urs of 7 a.m. and 10 p.m. As B [W of Carlsbad is not expected to operate before 7 a.m. or after 10 p.m. on any day, the project- generated noise must not exceed 55 dB L EQ at no ise-sensitive property lines. According to the Carlsbad Noise Element to the General Plan, noise-sensi tive uses include schools, hospitals, places o f worship, and residences. As the surrounding property to the cast is zoned as Open Space (OS) and the properties to the north, south, and west are zoned Regional Commercial (R), they arc not considered to be noise-sensitive receivers, and no noise limits would apply in these locations. To determine tl1e compatibility of the proposed project with the ci ty noise exposure guidelines, the noise compatibility matrix was used. The City of Carlsbad oise Element to the General Plan states that exterior noise levels at commercial uses and outdoor uses (such as parks and o pen space) should not exceed 70 d HA DNL. As ONT. is typically used to measure transportation noise, a noise limit of 70 dB A L i;Q was applied to surrounding pr.operty lines. Pertinent sections of the City of Carlsbad oise Element to d1c General Plan arc provided as AppcndL'C B. 3.0 Environmental Setting 3.1 Existing Noise Environment An on-site inspection was conducted on the morning of Wednesday, June 12, 2019. The ex1st111g noise environment consists primarily of traffic traveling on surrounding roadways, aircraft noise associated with McClellan-Palomar Airport, train noise, and mechanical noise from existing buildings on site. brief ambient noise measurement was taken during the inspection, for a duration of 15 minutes. The microphone position was approximately fi ve feet above the existing grade. Tne measured noise level is shown in Table 1 and the measurement location is shown in Figure 3. Table 1. On-Site Noise Measurement Conditions and Results Date Wcdncsday,Junc 12, 20 19 Time 1 lJ:07 a.m. -10:22 a.m. Conditions Pardy cloudy skies, light wi nd at 3 mph, tcmpcrau1re in the upper 60s, with moderately high humidity Measured Noise Level 69.9 <lRJ\ LFQ Eilar Associates, Inc. 3.2 Future Noise Environment The future noise environment in the vicinity of the project site will be primarily a result of the same noise sources, as well as the noise generated by the proposed mechanical equipment on site, which includes 17 service bays (nine at the colfaion center and eight at the smog center), nine detailing/programming bays at the comsion center, four rooftop air conditioning units (t\.VO at the collision center, one at the smog center, and one at the car rental center), three rooftop exhaust fans (one per evaluated building), and a paint booth (to be located at the comsion center), in order of greatest to least noise impact. The service bays are expected to use equipment such as air compressors, power tools, and vacuums. o manufacturer information was available for this equipment; however, based on measurements of a similar operational facility performed by Eilar J\ssociates on April 23, 2015, the service bays are expected to generate a noise level of approximately 66.3 dB A at a distance of 25 feet from the service garage opening. The detailing and programming bay · are expected to use equipment such as pressure washers and vacuums. o manufacturer information was available for this equipment; however, based on measurements of similar equipment performed by Eilar ssociates on April 23, 2015, the detailing and programming bays are expected to generate a noise level of approximately 65.5 dB1\ at a distance of 15 feet from the equipment. The rooftop air conditioning units are expected to be equivalent to be the model T /YSC1201134W, manufactured by Trane. As the manufacturer provides octave band sound power levels for the units, the provided octa e band levels were incorporated into the noise model as such. The rooftop exhaust fan .is expected to be equi valent to be the model G-300-C-VGD, manufactured by Greenheck. As the manufacturer provides octave band sound power levels fo r the units, the provided octave band levels were incorporated into the noise model as such. The pa.int booth is proposed to be the model 99273 pa.int spray booth, manufactured by Garmat USA. As the noise levels for the paint booth were provided in broadband sound pressure levels at a specified distance (52 dBA as measured at a distance of 20 feet from the booth), sound pressure levels were converted to sound power levels using the reference distance given, and a standard frequency spectrum typical of an air compressor was applied. Sound power levels of the proposed equipment arc shown in Table 2, and manufacturer sheets arc provided in Appendix C. Table 2.

Please refer to J .'igurc 5 for a graphical representation of the mechanical cguipmcnt locations on site. o other proposed cguipment on site is anticipated to generate significant levels of noise. 4.0 Methodology and Equipment 4.1 Methodology .Modeling of the outdoor noise environment is accomplished using CadnaA Version 2020, which is a model-based computer program developed by DataKustik for predicting noise impacts in a wide variety of conditions. CadnaA (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. Noise standards used by CadnaA that arc particularl y relevant to this analysis include TSO 9613 (Attenuation of sound during propagation outdoors). CadnaA provides results that arc in line with basic acoustical calculations for distance attenuation and barrier insertion loss. 4.2 Measurement Equipment Some or all of the following cyuipment was used at the site to measure existing noise levels: • Larson Davis Model LxT Type 1 Sound Level Meter, Serial # 4084 • Larson Davis Model Cf\250 Type 1 Calibrator, Serial # 2106 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 ational Standards Institute specifications for sound level meters (A SJ S 1.4). AU instruments arc maintained with ational Bureau of Standards traceable calibration, per the manufacturers' standards. 5.0 Operational Noise Impacts oisc levels of the proposed equipment we re calculated using CadnaA at surrounding properties to the south, cast (across Car Country Drive), and wes t. ;\II receivers were calculated at a height of fi ve feet above grade, to account for the height of an average individual's cars above the ground. Calculations include the shielding that will be provided by th e proposed on-site structures. Appropriate duty cycles were applied to the mechanical eguipment proposed to be opcratino-on site. Based on professional experience, the detailing/programming bays arc expected to be in operation about 50% of the time, and therefore were evaluated ass uming that each bay would be in operation for 30 minutes per hour. As th e reference noise level for service bays is an average noise level measured over the course of one hour, this noise level accounts for typical duty cycles of eyuipment in use, and therefore, service bays were input into the model as operational for the entire hour. The rooftop air conditioning units and exhaust fan were evaluated as being operational during the entire hour. TI1cse scenarios arc assumed to be a worst-case estimate of usage of eguipment on the proposed project site. Calculations arc shown in Table 3 and noise contours are shown in Figure 5.

This analysis is based upon a current worst-case scenario of anticipated equipment for tl,is facili ty. Substitution of equipment wit!, higher noise emission le els may invalidate tl,e recommendations of this study. These conclusions and recommendations arc based on the best and most current project-related information available at the time this study was prepared. 7 .0 Certification J\ll recommendations for noise control arc based on the best information available at the time our consulting services are provided. I lowever, as there are many factors involved in sound transmission, and Eilar Associates has no control over the construction, workmanship, or materials, Eilar J\ssociates is specifically not liable for final results of any recommendations or implementation of the recommendations.

These standards apply to the noise sources themselves, as measured at the edge of the property line; noise caused by motor vehicles traveling to and from the site is exempt from this standard. TABLE 5-2: ALLOWABLE NOISE EXPOSURE1 LAND USE Residential Motels, Hotels Hospitals, Residential Care Facilities, Schools, libraries, Museums, Churches, Day Care Facilities Playgrounds, Parks, Recreation Uses Commercial and Office Uses Industrial Uses OUTDOOR ACTIVITY' • AREAS (OBA CNEL) 604 65 65 65 65 70 INTERIOR SPACES (OBA CNEL) 45 45 45 50 50 65 1 Development proposed within the McClellan-Palomar Airport Area of Influence shall also be subject to the noise compatibility policies contained in the ALUCP. 2 For non-residential uses, where an outdoor activity area is not proposed, the standard does not ap- ply. Where the location of outdoor activity areas is unknown, the exterior noise level standard shall be applied to the property line of the receiving use. Where it ,snot possible to reduce noise in outdoor activity areas to the allowable maximum, levels up to 5 dB higher may be allowed provided that available exterior noise level reduction measures have been Implemented and Interior noise levels are in compliance with this table. 4 An exterior noise exposure level of 65 dBA CNEL is allowable for residential uses on a mixed-use project and for residential uses within the McClellan-Palomar Airport Area of Influence, pursuant to the noise compatibility policies contained in the ALUCP.

Policies Land Use and Noise Compatibility 5-P.1 Acceptability of Use Location. Use the noise and land use compat- ibility matrix (Table 5-1) and Future Noise Contours map (Figure 5-3) as criteria to determine acceptability of a land use, including the improvement/construction of streets, railroads, freeways and highways. Do not permit new noise-sensitive uses-including schools, hospitals, places of worship, and homes-where noise levels are "normally unacceptable" or higher, if alternative locations are available for the uses in the city. 5-P.2 Required Noise Analysis. Require a noise analysis be conducted for all discretionary development proposals (except for develop- ments of single family homes with four units or fewer) located where projected noise exposure would be other than "normally acceptable". A required noise analysis should: a. Be prepared by a certified noise consultant or acoustical engineer; b. Be funded by the applicant; c. Include a representative, on-site day and night sound level measurement; d. Include a delineation of current (measured) and projected (General Plan or 10 years in future, whichever horizon extends further out) noise contours; I I I I I I I I I I I I I I I I I I Appendix C ~Ianufacturer Data Sheets • Eilar Associates, Inc.

Results may vary by location due to site conditions and other factors beyond the control of the manufacturer. Scope: A representative Garmat USA, Inc. paint spray booth with model 99273 mechanical package, comprised of a direct gas fired heated air makeup unit and exhaust unit, were tested for sound levels at location described below. Equipment Location: 1501 West Tufts Avenue, Unit F Englewood, CO 80110 General: Decibel readings were made at 7:45 AM using a BEHA model 93-20 Sound Level Meter. The unit was calibrated before measurements began. All readings have been made in Decibels and were recorded both inside the building that housed the paint spray booth as well as the exterior of the building. Measurements made inside of the building were done from three to thirty-seven feet from the mechanical package with the sensor of the sound level meter pointed directly at the mechanical package. The bay door of the building was opened and exterior measurements were made starting at the bay door opening and finishing at one hundred feet from the bay door with the sensor of the sound level meter pointed directly at the bay door and slightly up to sample the sound from the duct openings on the roof of the building. A series of ambient measurements were made after calibration of the sound meter. The mechanical package was turned on and the measurements were repeated. At the end of the testing the sound level meter was checked for calibration and showed no change. Ambient Readings: Inside of building: @3' 42dB @9' 42dB @15' 42dB @21' 41dB @27' 41.SdB Outside of building: @door 48dB @20' 48dB @40' 48.SdB @60' 48dB @80' 48dB @ 100' 52dB (close to street) Mechanical package running: Inside of building: @3' 63dB @9' 60dB @15' 60dB @21' 58dB @27' 56dB Outside of building: @door 54dB @20' 52dB @40' SOdB @60' 48dB @80' SOdB @ 100'52dB (close to street) Readings throughout paint spray booth interior with mechanical package running: Anthony Demarest Controls Engineer and Compliance Mgr Garmat USA 61.SdB • Eilar Associates, Inc.
