Item 6C - Noise Study) esi engineering December 13, 2023 Mr. Tanner Brandt Christianson Companies 4609 33rd Avenue S., Suite 400 Fargo, ND 58104 Subject: DRAFT Summary Report for Car Wash Noise Control Tommy's Express Car Wash — Southlake, Texas Dear Mr. Brandt: We understand you are in the process of developing a new Tommy's Express Car Wash in Southlake, Texas. The proposed site is at the northeast corner of N. Pearson Lane and W. Southlake Boulevard (see Figure 1). Noise levels from the car wash sources must meet the City of Southlake Code requirements at the nearest receivers. ESI Engineering was asked to prepare calculations to evaluate car wash equipment noise levels, and if necessary, develop recommendations to meet the Code requirements. The following is a summary of our analysis results and recommendations. r1i Is , - - P 64 # Liar —� pooh �' u�hlake P.re-Sci�ool Figure 1 — Aerial image overlaid with the Tommy's Express Car Wash project site plan.

However, the west side of North Pearson Lane is in Keller, Texas. Figure 2 shows the proposed project site and the nearest property types as zoned by the City of Southlake and the City of Keller.

The project site has: • A proposed new retail center to the west side of the car wash site. • Nearby residential neighbors in nearly all directions. • Nearby commercial neighbors in nearly all directions. • A public utilities facility to the east. The current project layout has the car wash building located near the east side of the lot with the car wash entrance facing north and the exit facing south. Sixteen vacuums are shown at the head of parking stalls to the west of the car wash building. Mr. Tanner Brandt Christianson Companies DRAFT Noise Code Requirements December 13, 2023 Page 3 States and cities often have requirements for noise level limits at neighboring receivers. Based on our review of the State of Texas laws that relate to nuisances, we are only aware of "Chapter 42. Disorderly Conduct And Related Offenses" of the Texas Penal Code (provided in Attachment A) having noise level limitations. Section c.2 states that, "a noise is presumed to be unreasonable if the noise exceeds a decibel level of 85 after the person making the noise receives notice from a magistrate or peace officer that the noise is a public nuisance." In our opinion, a noise level of 85 dBA at residential or commercial receivers would be perceived as excessively loud and result in many complaints. We have also reviewed the Noise Nuisances portion within the City of Southlake Code of Ordinances (provided in Attachment B). "Section 11-61. — Offenses" has requirements for maximum allowable noise levels by receiving property type. Table 1 shows the noise limits given in this section of the Code. Since the Code does not clarify how the noise levels should be evaluated, we assume the intent is to evaluate average (LAeq') noise over a long period of time (e.g., 10 minutes, 1 hour, etc.) at the receiving property line or anywhere on the receiving property. Table 1 - City of Southlake Prima Facie Maximum Allowable Noise Levels Property Receiving Sound Daytime Nighttime Sundays Residential 60 dBA 55 dBA 55 dBA Commercial 70 dBA 65 dBA 65 dBA "Section 11-60. — Definitions" has the following definitions that relate to the noise level requirements in Table 1: • Residential means any property used for temporary or permanent dwelling purposes. • Commercial means property used for purposes other than residential or agricultural regardless of whether the property has a commercial zoning designation. • Daytime means the hours from 7:00 AM to 9:00 PM. • Nighttime means the hours from 9:00 PM until 7:00 AM. • A -weighted sound level means the sound pressure level in decibels as measured on a sound level meter using the A -weighted network. The sound pressure level so read is designated in dB(A) or dBA.2 ' LAeq, or equivalent A -weighted sound pressure level, is the average overall A -weighted sound level measured in pascals during a particular time period that is then converted to decibels. 2 As defined in ANSI S12:60, "A -weighted sound level. Sound pressure level measured with a conventional frequency weighting that roughly approximates how the human ear hears different frequency components of sounds at typical listening levels for speech. The A -weighting (see IEC 61672-1) attenuates the low -frequency (or low -pitch) content of a sound. A -weighted sound level is expressed in decibels, unit symbol dB[A]." Mr. Tanner Brandt Christianson Companies DRAFT December 13, 2023 Page 4 The City of Keller Code of Ordinances also has a Noise Ordinance section (provided in Attachment C). While the Keller Code provides descriptions of possible noise nuisances, it does not give specific noise level limitations. In the absence of clearly defined noise level limits in the Keller Code, we recommend using the City of Southlake noise level requirements for similar receiving properties within the City of Keller. We understand the proposed car wash will only operate during daytime hours on weekdays and weekend days. Therefore, based on the most stringent limits for Sunday operations in the City of Southlake Code, the maximum allowable noise levels for the project are 55 dBA at residential receivers and 65 dBA at commercial receivers (highlighted green in Table 1 above). Existing Car Wash Measurements To determine the car wash noise sources and equipment noise levels for the Southlake project, noise measurements were made at an existing car wash. On Tuesday, February 8, 2022, Mr. Ryan Skoug of ESI Engineering visited an existing Tommy's Express Car Wash in Mounds View, Minnesota to make observations and perform noise measurements. We understand that the equipment for the Southlake car wash will be the same as that used in Mounds View. Sound measurement data sheets are provided in Attachment D. The following is a summary of the visit findings: 1. There were multiple Tommy Car Wash Systems vacuums at the site (see Figure 3). No mufflers were installed on top of the vacuums. The measured LAeq sound pressure level at a distance of 10' from one running vacuum was 72 dBA. Figure 3 — Photo of a vacuum at the Mounds View Tommy's Express Car Wash. Mr. Tanner Brandt Christianson Companies DRAFT December 13, 2023 Page 5 2. The dominant noise source near the car wash exit (see Figure 4) was the drier system, which had eighteen blowers (shown in Figure 5). The measured LAeq sound pressure level at a distance of 58' from the exit, with a zero -degree offset from the exit centerline, was 83 dBA. When a measurement was made 54' from the exit with a 45 degree offset from the exit centerline, the measured LAeq was 79 dBA. Figure 4 — Photo of the Tommy's Express Car Wash exit with drier system beyond. Figure 5 — Photo of the Tommy's Express Car Wash drier system. Mr. Tanner Brandt December 13, 2023 Christianson Companies Page 6 DRAFT 3. The dominant noise sources near the car wash entrance were the automated audio system (see Figure 6) and the drier system at the other end of the car wash. Noise from the other car wash equipment inside the building was also audible. The measured LAeq sound pressure level at a distance of 48' from the entrance, with a zero -degree offset from the entrance centerline, was 72 dBA. Figure 6 — Photo of the Tommy's Car Wash entrance. 4. The car wash building had louvers with dampers on each side (see Figure 7). The dampers could be opened and closed to control the release of heat and steam from inside the building, which also allows sound to leak out. The dominant noise source radiating from the dampers was the drier system. Noise from the other car wash equipment inside the building was also audible. The measured LAeq level at a distance of 8.5' from one open damper (shown in Figure 8) was 76 dBA. Mr. Tanner Brandt Christianson Companies DRAFT December 13, 2023 Page 7 Figure 7 — Photo of the Tommy's Express Car Wash with sidewall louvers circled. e Figure 8 — Photo of the Tommy's Express Car Wash with an open damper circled. Mr. Tanner Brandt Christianson Companies DRAFT Noise Analysis December 13, 2023 Page 8 Calculations were prepared to determine the car wash noise levels at the nearest receiver locations to the Southlake project site. The measured LAeq sound pressure level results from the Tommy's Express Car Wash in Mounds View, MN were used as source data for the analysis. The results were converted into LAeq sound power levels to determine the noise from each source independent of distance. Table 2 shows the sound power levels used for each noise source. Table 2 — Car Wash Source Sound Power Levels Source Source Height in Noise Model Sound Power Levels (dBA) Per Frequency (Hz) Overall Sound Power Level (dBA) 63 125 250 500 1 k 2k 4k 8k One Vacuum 4.5' 56 57 66 75 82 86 84 80 90 Exit Opening 5' 70 83 93 102 103 100 94 84 107 Entrance Opening 5' 62 71 81 87 91 89 82 77 95 Open Side Louver 12' 58 71 81 86 89 85 76 68 92 Noise contour plots were prepared to help evaluate the car wash noise levels at the proposed project site. The calculations included the car wash building, all other nearby buildings, and a source for each of the car wash noise producers. Sources were the exit opening, entrance opening, fourteen east -facing sidewall louvers, sixteen west -facing sidewall louvers, and sixteen vacuums near the head of parking stalls to the west of the car wash building. The existing car wash measurement results showed that drier system noise at the exit and entrance was directional. At a 45 degree offset from the centerline, the sound power was about 5 dBA quieter. This "tunnel effect" of the sound dispersion from the exit and entrance was included in the noise calculations. We reviewed the project site ground elevations on Google Earth and found that the site has an increase in elevation to the north, and a decrease in elevation to the south. Based on our review these elevations, we created the topographic contour lines that are shown on the aerial image in Figure 9. Because the effectiveness of barrier noise reduction changes depending on the elevation of the source and receiver positions, these topo lines were included in our noise calculations and contour plots. Mr. Tanner Brandt Christianson Companies DRAFT December 13, 2023 Page 9 Figure 9 - Aerial image showing the topo lines that were included in the noise calculations. We understand the project will also include the following options to reduce the car wash equipment noise levels at nearby receiver properties: 1. A 520' long, 8' tall stone fence will be installed along the north property line of the project site. We assume the following: a. The 8' fence height is relative to the elevation of the ground. b. The fence will have no air gaps from ground up and from end to end. c. The fence panels will have a minimum sound isolation rating (sound transmission class, or STC') of STC 25. We understand the project team is considering the use of a Hilltop Concrete fence (see Figure 10), which has a laboratory tested STC 35 rating (see test report in Attachment E) that meets the minimum criterion. 3 Sound transmission class, or STC, is defined in ASTM standard C634-13 as, "a single -number rating calculated in accordance with Classification E413 using values of sound transmission loss. It provides an estimate of the performance of a partition in certain common sound insulation problems." It is based on laboratory tests of wall and floor/ceiling assemblies that serve as acoustical barriers, with higher values representing better insulation. Mr. Tanner Brandt Christianson Companies DRAFT December 13, 2023 Page 10 Figure 10 — Hilltop Concrete photo of a concrete fence. 2. The loudest car wash noise source is the drier system. We understand the individual Tommy Car Wash Systems blowers can be installed with variable frequency drives (VFDs) to control blower speeds between 0 Hz (00/o speed) and 60 Hz (100% speed). Based on a Tommy Car Wash Systems report dated May 18, 2021 (provided in Attachment F), the car wash noise levels were reduced by 10 dBA when the blowers ran at 40 Hz (67% speed). For the Southlake car wash, the blowers will run at no more than 40 Hz to achieve about 10 dBA of blower noise reduction at the car wash exit, entrance, and side wall louvers. 3. Tommy Car Wash Systems has optional mufflers that can be provided with the vacuums. Based on a Tommy Car Wash Systems report (provided in Attachment G), installing a P-VAC-335 muffler (shown in Figure 1 1) on top of a vacuum reduces noise levels by 9 dBA and does not affect the vacuum suction. For the Southlake car wash, the vacuums will all be installed with the P-VAC-335 mufflers. Mr. Tanner Brandt Christianson Companies DRAFT December 13, 2023 Page 11 Figure 11 — Photo of a Tommy Car Wash Systems vacuum with a P-VAC-335 muffler. The calculation results for these basis -of -design conditions are summarized in the noise contour plot shown in Figure 12. The results show that the loudest overall noise level at a residential receiver is 55 dBA, and 64 dBA at a commercial receiver, which meets the 55 dBA and 65 dBA criteria, respectively. No other modifications to the car wash equipment are necessary. Mr. Tanner Brandt Christianson Companies DRAFT December 13, 2023 Page 12 Figure 12 - Noise contour plot showing the Tommy's Express Car Wash equipment noise levels at the proposed project site. Mr. Tanner Brandt Christianson Companies DRAFT Conclusions December 13, 2023 Page 13 ESI Engineering was asked to evaluate equipment noise levels for a proposed Tommy's Express Car Wash in Southlake, Texas. While the State of Texas does not have noise level limitations that apply to this project, the City of Southlake Code of Ordinances require that the car wash noise levels not exceed 55 dBA and 65 dBA at residential and commercial receivers, respectively. Calculations were prepared to evaluate car wash equipment sound levels at the nearest receiver properties to the project site. The calculations were based on the following: • Measured noise levels from a Tommy's Express Car Wash in Mounds View, Minnesota. • A 8' tall stone fence along the north property line of the project site. • The car wash drier blowers operate at a maximum 40 Hz (10 dBA reduction). • Mufflers are installed on the car wash vacuums (9 dBA reduction). These basis -of -design conditions produced calculated noise levels that met the City of Southlake requirements at the nearby residential and commercial receivers. No additional mitigation measures are necessary. We appreciate the opportunity to serve the needs of Christianson Companies on this project and remain available to assist in the resolution of these and any other matters. Please let us know if you have any questions or need more information. Sincerely, Ryan L. Skoug, P.E. (OR), INCE Bd. Cert Consulting Engineer ESI Engineering, Inc. Andrew A.J.

The noise. reduction is ac hiaved because the sound rnu-gt diffract over the top or around the sides of the barrier. This diffraction scatters the sound so that less of it reaches the listener. The practical limit of noise reduction which can be achieved by means of a barrier is 24 dS. Vvrherx choosing a barrier structure, the engineer wants to be sure that the sound which goes through the barrier is insignificant in coznparisou vuith the soured which diffracts over the barrier_ Since the limit of noise reduction for a barrier is 24 dB, if a barrier provides a transmission loss of about 34 dB, this concUtion is assured. However, in most practical applications of barriers, the noise reduction ' idnich is achieved is Tuach less than 24 dB, especially at low frequencies. In these situations, transrrdssion losses of much less than :34 dB are quite adequate. According to Western Electro-Acoustic Laboratory, Inc. (VYCAL) Soured Transmission Loss Test Deport TL95-1, your product achieves transmission loss (TL) of greater than 34 dB in most one-third octave bands above 80 H- A. traxtsirniission loss of 29 dl3 was measured at SO Hz. Even if the barrier cordigt_txation was such that a xioise reduction of 24 dB was achieved at SU Hz (which is very uni ikel y), the fact that your product has a TL of 29 dB in that band would only compromise the noise reduction by 1 dB to 23 dP. in conclusion, I would say that your product could f mction as barmier structure in almost every conceivable situation. As an acoustical consultant, I w[]uld not have any hesitation to approve your product to be used for any specified barriers. if you have any questions or if; vA-- can be- of Further assistance, please feel free to call.

Measurements were taken between 10:00pm and 12:00am on May 18th at the Hudsonville Location. Instrumentation & Procedure Measurements were recorded using an Extech Instruments Model 407730 Sound Level Meter. This meter is calibrated and meets the standards of the National Institute of Standards and Technology and conforms with ISO 10012 and ANSI Z540-1-1994. Sound levels were recorded both at ground level as well as at a height of 5 feet off the surface. Measurements were recorded as an average of a 5 second period at each point. Samples were recorded with minimum possible ambient noise pollution when applicable and with the standard blower motor configuration. Procedure was repeated with blower motor frequency adjusted in 10Hz increments from 60Hz to 10Hz. Atmospheric & Ambient Conditions Atmospheric data is taken from the weather station at Gerald R. Ford International Airport and is shown in Table 1. Ambient sound levels were recorded at the maximum distance from the tunnel exit with all wash functions turned off. Ambient sound levels ranged from a minimum of 50clB to a maximum of 60clB. It should be noted that while efforts were made to prevent contamination of data from ambient conditions, some noise pollution from the environment was unavoidable.
