The Human Beans' coffee shops provide convenient quality coffee, espresso, smoothies and hot chocolate. All Human Bean coffee shops are drive-through facilities; no tables or seating areas are provided. The site plan for the Human Bean drive-through coffee shop provides a single -sided drive -up design with a menu board and order station conveniently located in the landscaped area. The building is 600 sq. ft. and the drive-through lane may accommodate up to 5 stacked cars. Five on-site parking spaces and one loading space are provided for Human Bean's employees and the wholesale/distribution building. The project was approved by the Planning Commission; the Planning Commission did not adopt hours of operation for the project and they did not limit the hours of operation of the speaker mounted on the menu ordering board. Hours of Operation The proposed hours of operation are from 5 am to 9 pm daily. It is important for the Human Bean to open at 5 am to serve beverages to employees of local businesses, construction workers, and commuters. Limiting the Human Bean's hours would deprive the business of servicing customers during prime revenue time. Human Bean's main competitor opens for business at 4:30 am or at 5:00 am depending on their location within the City. Speaker at Menu Ordering Board At the Planning Commission hearing, a neighbor raised concerns regarding the hours of operation and the volume of the speaker. The Commissioners discussed the issue but did not adopt restrictive hours for the use of the speaker. To address the neighbor's concerns, 45 dB Acoustics completed an acoustical report 1 noise analysis (Report). Per their report, the three properties flanking the project site could be impacted from the noise emanating from the speaker. A summary of the results are discussed below and a copy of their report is attached for your reference. Planning Solutions 1360 New Wine Place Templeton, CA 93465 Planning Solutions plan ni ngsolutions(@,cha iter. net 805-801-6453 The project will use a speaker model that is equipped with an Automatic Volume Control System which automatically limits the volume of the speaker to a volume that is 15 dB above the ambient noise level measured one foot from the speaker. The use of the Automatic Volume Control System assures that the sound from the speaker • will beat or below the ambient noise level just 10 meters from the speaker, • will be below the ambient noise level at the property boundaries, and • will not be audible at the three locations that could be impacted by the speaker noise - adjacent properties lying to the north (R1), east (R2), and south (R3). n SFRwH�� t �.Occupatior ti' s SFR WarP-ase r' t Ij AD 1\1 Ilk V y ` tilfTra f'•;♦♦'4,}��� � it ► �• �l 1. •`l` •1� .'` ,� _" NO '.lf.i.� `. ,1i `•\ Y^ti r li Y -c e y5k.• ,\ +L I,'• '�� '� r a✓."i ''ice IR V. } ;k . �� �.. t.; , - �r � ✓ •fie � .ems '+ .�, 11 /e.' ..... •ii's./'',/ /—�. 017Iq@'" Figure 7: 45d6 Acoustics acoustical report dated January 7, 2020 Both the Noise Element of the General Plan and the ordinance allow up to 50 dB for daytime and up to 45 dB for nighttime. In the case of the Human Bean project, Section 9-14.05 (b) of the ordinance allows a higher level because the ambient noise level at the property boundary of the receiving site pre -project exceeds the level permitted by the ordinance at two of the three locations during daytime hours and at one of the three locations during nighttime hours. Planning Solutions 1360 New Wine Place Templeton, CA 93465 Planning Solutions pLanr-Cingsolutions@charter.net 805-801-6453 Table 1 below provides data for the maximum pre and post -project daytime noise levels and maximum pre and post project nightime noise levels at each of the three adjacent properties. As stated above, the maximum pre and post project daytime noise level for R1 and R3 exceed the ordinance requirement of 50 dB during the daytime. The 45 dB nightime level is exceeded at R1. Since the level of the noise at the property line does not increase post project, there is no impact to the adjacent parcels.

The concern expressed by the neighbor and discussed by the Planning Commissioners was addressed and the report determined that their concerns have no factual basis. Even in the unlikely event that the speaker could be heard, it would be below the standard established by the Noise Element. In order for the Human Bean to be a viable addition to the City's businesses, the hours of operation must be similar to their competitors and the conditions placed on the project must be based on factual data. We respectfully request that you uphold the Planning Commission's approval of this project, deny the appeal, and adopt appropriate conditions of approval.

Box 3067 805 801-0453 Atascadero, CA Stockton, CA 95213 I ExeCUt1VC SLlInniary This project was analyzed for compliance with the City of Atascadero's General Plan Noise Element. Operational hours for the drive-through are 5am to 9pm. Traffic counts from the City's 2015 published levels were conservatively adusted to 6,000 AADT which more than accounts for I% per year growth factor. This AADT was then parsed into day, evening, and nighttime traffic count per hour for present-day traffic noise for EI Camino Real—this becomes 382 cars/hour for the twelve daytime hours of 7 am to 7 pm, 200 cars/hour within the three evening hours from 7 pm to 10 pm, and 91 cars/hour for the nine nighttime hours from to 10 pm to 7 am. A 5 -car queue of idling vehicles was included as an incremental noise source for all operational hours of the business. An order -speaker stand system utilizing dynamic background/ambient noise level adjustment to within 15 dB over the current background level was modeled. This system provides an obvious benefit over other conventional systems without this technology. Regardless of the ambient background noise level, the speaker's sound level will adapt to existing hourly daytime and nighttime noise levels. Under the above conditions and assumptions, the drive-through coffee shop is anticipated to fully comply with the Noise Element requirements for the City of Atascadero. 45dB Acoustics, LLC Atascadero Drive-Throu h Coffee Sha 3 Introduction This sound level assessment is intended to determine the potential impact of on-site noise associated with operations and patrons at the proposed drive-through order coffee shop. The project was analyzed assuming operational drive-through hours for the business of 5 am to 9 pm. The following topics are presented: • The topographical relationship of on-site and off-site transportation noise sources in relation to the single -story residences opposite the proposed project. • Identification of noise sources and their characteristics, including predicted noise levels at the exterior of the potentially sensitive residential land use to the south. • Determination of ambient sound levels and mapping of sound level contours for various scenarios, including speaker -post drive-through ordering. • Basis for the sound level prediction which is obtained from published data, the noise attenuation measures to be applied, and an analysis of speaker board sound level scenarios. • Information on fundamentals of noise and vibration to aid in interpreting the report. 4 Project Location The proposed project is located at 7835 El Camino Real, this street being the priinary transportation noise source for the area. page 2 of 15 noise nianagenient : room acoustics : environmental impact www.45dB.com 45dB Acoustics, LLC Atascadero Drive -Through Coffee Shop Figure 1: Vicinity Map of Project Location with plan overlaid 5 Regulatory Setting Noise regulations are addressed by federal, state, and local government agencies. Local policies are generally adaptations of federal and state guidelines, adjusted to prevailing local condition. 5.1 Local Regulation The City of Atascadero General Plan, Noise Element provides regulation and guidelines regarding noise. The Noise Element provides the conclusions, recommendations, and strategies necessary to ensure an appropriately quiet and pleasurable interior environment for all. Since the regulation of transportation noise sources such as roadway and train traffic primarily fall under either State or Federal jurisdiction, the local jurisdiction generally uses land use and planning decisions to limit locations or volumes of such transportation noise sources, to avoid development within noise impact zones, or to shield impacted receivers or sensitive receptors. The maximum allowable noise exposure to assess new stationary noise sources at the nearest receiving land use property line, are the applicable noise limits (Figure 2). In this report we have evaluated the entire propertly boundary for each adjacent neighboring property. page 3 of 15 noise management : room acoustics : environmental impact www.45dB.eom 45dB Acoustics, LLQ' Atascadero Drive-Throuah Coffee 5h Figure 2: Maximum Allowable Noise Exposure, City of Atascadero Table n--4.

The results are mapped as sound level contours on the following pages. In this case, the City of Atascadero has published traffic counts for this location of El Camino Real (Figure 3) from June of 2015, which we conservatively adjust upward to 6,000 AADT.

Mounted on the speaker post, the speaker sound power level includes the order taker's voice. The speaker audio output must be loud enough to be clearly heard by the customer over the noise of the customer's vehicle, any local traffic and other ambient background noise in the area. However, if it is too loud, the sound may be objectionable to neighbors or even violate specific regulations. The base station speaker used in this project is equipped with a feature known as Automatic Volume Control or "AVC" which can be used to reduce the outbound sound pressure level based on ambient noise. When AVC is active, the speaker output sound level is reduced to a level that is 15 dB above the ambient noise level at the speaker post microphone, and never increases in level above what would be heard with AVC turned off. This feature considerably reduces the Sound Pressure Level (SPL) during quiet periods and may help in satisfying local requirements. Documentation of such a system, made by HCL, is included in the appendix. Sound levels are measured in units of dB SPL and include a frequency variable weight referred to as "A Weighting", referred to as dBA. The sound pressure level from a speaker decreases (attenuates) as the distance away increases. However, it can be difficult to predict how much reduction will actually occur in a real-world setting. For a single point sound source, the SPL drops approximately d dB for every doubling of the distance from the source. Thus, starting at one foot away from the speaker, the level will be 36 dB lower at 64 feet away. Buildings, automobiles, walls and street traffic will all affect the sound's direction and attenuation rate. The speaker output sound level is never more than 15 dB above the ambient noise level at one foot distance from the speaker. This is particularly beneficial at night when there is less traffic on surrounding streets and fewer cars in the drive-through. Because the speaker is adjusting sound level continuously, it ensures that the output level is high enough to be heard by the customer whatever the surrounding sound level may be. As an example, if the ambient noise level is 47 dBA, the speaker adjusts output sound level to approximately 62 dBA at a position about 1 ft from the speaker. Given this condition, the SPL will be below the ambient noise level less than 20 ft away from the speaker post. The front elevation of the nearest residence at 7765 El Camino Real is approximately 65 feet from the speaker post. Even with the menu board acting as a solid noise barrier wall located directly behind the speaker, the noise level of the speaker falls to the ambient level, i.e., 15dB attenuation, at approximately 10m distance. The customer's vehicle acts to further block that sound propagation in the opposite direction. Speaker sound levels will fall well below ambient sound level in all directions within the project property boundaries. This is demonstrated in the project -only sound level contours from the speaker and cars in Figure 6, and the scenario with page 6 of 15 noise managen2ent : room acoustics : environniental in�pact w,"v.45dI3.com 45dI Acoustics, LLC Atascadero Drive -Through Coffee Shop the project in place in addition to traffic in Figure 7. The worst-case, or highest, noise level locations for each propertly line are identified in Figure 7, as R1, R2, and R3 as shown. Since the speaker self -adjusts to the noise level measured at the speaker post, a noisy vehicle will drive the output sound level up. Thus, the use of automatic volume control speakers will not guarantee that the SPL is below any particular level for all vehicles or conditions. However, it will keep the speaker output level from becoming excessively loud in relation to existing ambient sound levels. page 7 of 15 noise management : room acoustics : em,ironmental impact www.45dB.com 45dB Acoustics, LLC Atascadero Drive -Through Coffee Shop Figure 6: Project -only sound level contours for daytime (no traffic noise) 32 26 n 4., k.f i 1�Y ti 4a f'• 1111','; 2SJ hs31 Q Bn AN. air I ti ',�• •�f• y • Figure 7: Total sound level contours for nighttime (with traffic noise) page 8 of 15 noise management : room acoustics : environirzenlal impacl kvwkk1.45dB.com 45dB Acoustics, LLC Atascadero Drive -Through Coffee Shop Table i below provides a summary of the existing daytime ("Ld') and nighttime ("Ln") levels for the highest noise levels due to the project at the worst-case propertly line noise levels for the three closest neighbors, Table 1 shows that there is a negligible, or less -than -significant impact for all receivers.

The drive-through Automatic Volume Control speaker system means that the ordering board and queue for drive-thru will not be audible at any of the neighboring addresses. for 45dB Acoustics, LLC A California Limited Liability Company K2 by Sarah Taubitz, MSME, Member INCE-USA page 9 of 15 noise management : room aeonstics environmental impact www.45dB.com 4MBAcoitstics, LLC Atascadero Drive -Through Coffee Shop S Appendix 8.1 Terminology/Glossary A -Weighted Sound LeveI (dBA) The sound pressure level in decibels as measured on a sound level meter using the internationally standardized A -weighting filter or as computed from sound spectral data to which A -weighting adjustments have been made. A -weighting de-emphasizes the low and very high frequency components of the sound in a manner similar to the response of the average human ear. A - weighted sound levels correlate well with subjective reactions of people to noise and are universally used for community noise evaluations, Air -borne Sound Sound that travels through the air, differentiated from structure -borne sound. Ambient Sound Level The prevailing general sound level existing at a location or in a space, which usually consists of a composite of sounds from many sources near and far. The ambient level is typically defined by the Leq level. Background Sound Level The underlying, ever-present lower level noise that remains in the absence of intrusive or intermittent sounds. Distant sources, such as Traffic, typically make up the background. The background level is generally defined by the L90 percentile noise level. Community Noise Equivalent Level (CNEL) The Leq of the A -weighted noise level over a 24-hour period with a 5 dB penalty applied to noise levels between 7 p.m. and 10 p.m. and a 10 dB penalty applied to noise levels between 10 p.m. and 7 a.m. CNEL is similar to Ldn. Day -Night Sound Level (Ldn) The Leq of the A -weighted noise level over a 24-hour period with a 10 dB penalty applied to noise levels between 10 p.m. and 7 a.m. Ldn is similar to CNEL. Decibel (dB) The decibel is a measure on a logarithmic scale of the magnitude of a particular quantity (such as sound pressure, sound power, sound intensity) with respect to a reference quantity. DBA or dB(A) A -weighted sound level. The ear does not respond equally to all frequencies, but is less sensitive at low and high frequencies than it is at medium or speech range frequencies. Thus, to obtain a single number representing the sound level of a noise containing a wide range of frequencies in a manner representative of the ear's response, it is necessary to reduce the effects of the low and high frequencies with respect to the medium frequencies. The resultant sound level is said to be A -weighted, and the units are dBA. The A -weighted sound level is also called the noise level. page 10 of 15 noise management : room acoustics : environmental impact www.450.coin 45dB Acoustics, LLC Atascadero Drive -Through Coffee Shop Energy Equivalent Level (Leq) Because sound levels can vary markedly in intensity over a short period of time, some method for describing either the average character of the sound or the statistical behavior of the variations must be utilized. Most commonly, one describes ambient sounds in terms of an average level that has the same acoustical energy as the summation of all the time -varying events. This energy -equivalent sound/noise descriptor is called Leq. In this report, an hourly period is used. Field Sound Transmission Class (FSTC) A single number rating similar to STC, except that the transmission Ioss values used to derive the FSTC are measured in the field. All sound transmitted from the source room to the receiving room is assumed to be through the separating wall or floor -ceiling assembly. Outdoor -Indoor Transmission Class (RITC) A single number classification, specified by the American Society for Testing and Materials (ASTM E 1332 issued 1994), that establishes the A -weighted sound level reduction provided by building facade components (walls, doors, windows, and combinations thereof), based upon a reference sound spectra that is an average of typical air, road, and rail transportation sources. The ❑ITC is the preferred rating when exterior facade components are exposed to a noise environment dominated by transportation sources. Percentile Sound Level, Ln The noise level exceeded during n percent of the measurement period, where n is a number between 0 and 100 (e.g., L 10 or L90) Sound Transmission Class (STC) STC is a single number rating, specified by the American Society for Testing and Materials, which can be used to measure the sound insulation properties for comparing the sound transmission capability, in decibels, of interior building partitions for noise sources such as speech, radio, and television. It is used extensively for rating sound insulation characteristics of building materials and products. Structure -Borne Sound Sound propagating through building structure. Rapidly fluctuating elastic waves in gypsum board, joists, studs, etc. Sound Exposure Level (SEL) SEL is the sound exposure level, defined as a single number rating indicating the total energy of a discrete noise -generating event (e.g., an aircraft flyover) compressed into a 1 -second time duration. This level is handy as a consistent rating method that may be combined with other SEL and Leq readings to provide a complete noise scenario for measurements and predictions. However, care must be taken in the use of these values since they may be misleading because their numeric value is higher than any sound level which existed during the measurement period. page 11 of 15 noise management : room acoustics : environmental impact www.45dB.com 45dB Acoustics, LLC Atascadero Drive -Through Coffee Shop Subjective Loudness Level In addition to precision measurement of sound level changes, there is a subjective characteristic which describes how most people respond to sound: A change in sound level of 3 dBA is barely perceptible by most listeners. A change in level of b dBA is clearly perceptible. A change of 10 dBA is subjectively perceived as being twice {or half} as loud. 8.2 Calculating CN)L Housing and Urban Development (HUD) Code of Federal Regulations (CFR), Part 51 Environmental Criteria and Standards, along with Federal Highway Administration (FHWA) guidelines are used for estimating CNEL values based on "design hour" traffic flow measurement. Highway projects receiving Federal aid are subject to noise analyses under the procedures of the FHWA. Where such analyses are available they may be used to assess sites subject to the requirements of this standard. The Federal Highway Administration employs two alternate sound level descriptors (23 CFR 772.12): (i) The A -weighted sound level not exceeded more than 10 percent of the time for the highway design hour traffic flow, symbolized as L10; or (ii) The equivalent sound level for the design hour, symbolized as Leq. The day -night average sound level may be estimated from the design hour L10 or Leq values by the following relationships, provided heavy trucks do not exceed 10 percent of the total traffic flow in vehicles per 24 hours and the traffic flow between 10 p.m. and 7 a.m. does not exceed 15 percent of the average daily traffic flow in vehicles per 24 hours: (a) CNEL - L10 (design hour) - 3 decibels (b) CNEL Leq (design hour) decibels Existing highway traffic noise measurements are made to represent an hourly equivalent sound level, Leq. Statistical accuracy requires a minimum measurement of approximately eight minutes. Most highway agencies have automated measurement equipment and typically measure 15 -minute time periods to represent the Leq. This is acceptable if unusual events do not occur during the noisiest hour. Measurements along low-volume highways may require longer measurement periods (e.g., 30-60 minutes) to attain desirable statistical accuracy. If information is not available to identify the noisiest hour of the day or if there is pub] is controversy at a specific location, 24-hour measurements may be necessary. The FHWA stipulates the use of noise meters with sufficient accuracy to yield valid data for the particular project (ANSI S 1.4-1983, TYPE II or better). The measurement procedure shall ensure measurements have consistent and supportable validity. Traffic conditions, climatic conditions, and land uses at the time of measurement shall be noted. page 12 of 15 noise management : room acoustics : environmental impact anm.45dB.com 45dB Acoustics, LLC Atascadero Drive -Through Coffee Shop 8.3 Traffic Noise Model (TNM) The Federal Highway Administration Traffic Noise Model (TNM) used for the sound level analysis in this study, contains the following components: 1. Modeling of five standard vehicle types, including automobiles, medium trucks, heavy trucks, buses, and motorcycles, as well as user -defined vehicles. 2. Modeling both constant- and interrupted -flow traffic using a field -measured data base. 3. Modeling effects of different pavement types, as well as the effects of graded roadways. 4. Sound level computations based on a one-third octave -band data base and algorithms. 5. Graphically -interactive noise barrier design and optimization. 6. Attenuation over/through rows of buildings and dense vegetation. 7. Multiple diffraction analysis. 8. Parallel barrier analysis. 9. Contour analysis, including sound level contours, barrier insertion loss contours, and sound -level difference contours. These components are supported by a scientifically founded and experimentally calibrated acoustic computation methodology, as well as a flexible data base, made up of over 6040 individual pass -by events measured at forty sites across the country. 8.4 SoundPLAN Acoustics Software SoundPLAN, the software used for this acoustic analysis, is an acoustic ray -tracing program dedicated to the prediction of noise in the environment. Noise emitted by various sources propagates and disperses over a given terrain in accordance with the laws of physics. Worldwide, governments and engineering associations have created algorithms to calculate acoustical phenomena to standardize the assessment of physical scenarios. Accuracy has been validated to be + 1- 2.7 dBA with an 85% confidence level. SoundPLAN is compliant with TNM standards described above. The software calculates sound attenuation of environmental noise, even over complex terrain, uneven ground conditions, and with complex obstacles. The modeling software calculates the sound field in accordance with ISO 9613-2 "Acoustics - Attenuation of sound during propagation outdoors, Part 2: General Method of Calculation." This standard states that "this part of ISO 9613 specifies an engineering method for calculating the attenuation of sound during propagation outdoors, in order to predict the levels of environmental noise at a distance from a variety of sources. The method predicts the equivalent continuous A -weighted sound pressure level under meteorological conditions favorable to propagation from sources of known sound emissions. These conditions are for downwind propagation under a well-developed moderate ground-based temperature inversion, such as commonly occurs at night." page 13 of 15 noise management : roam acoustics : environmental impact www.45d6.com 45dBAcoustics, LLC Atascadero Drive -Through Coffee Shop 8.5 Characteristics of Sound When an object vibrates, it radiates part of its energy as acoustical pressure in the form of a sound wave. Sound can be described in terms of amplitude (loudness), frequency (pitch), or duration (time). The human hearing system is not equally sensitive to sound at all frequencies. Therefore, to approximate this human, frequency -dependent response, the A -weighted filter system is used to adjust measured sound levels. The normal range of human hearing extends from approximately 0 to 140 dBA. Unlike linear units such as inches or pounds, decibels are measured on a logarithmic scale, representing points on a sharply rising curve. Because of the physical characteristics of noise transmission and of noise perception, the relative loudness of sound does not closely match the actual amounts of sound energy. Table 2 below presents the subjective effect of changes in sound pressure levels. Table 2. Sound Level Change Relative Loudness/Acoustic Energy Loss 0 dBA Reference 0% -3 dBA Barely Perceptible Chane 50% -5 dBA Readily Perceptible Change 67% -10 dBA Half as Loud 90% -20 dBA 114 as Loud 99% -30 dBA 118 as Loud 99.9% Source: Highway Traffic Noise Analysis and Abalement Policy and Guidance, U.S. Department of Transportalion, Federal Highway Administralion, Office of Environment and Planning, Noise and Air QualitBranch, June 1995. Sound levels are generated from a source and their decibel level decreases as the distance from that source increases. Sound dissipates exponentially with distance from the noise source. This phenomenon is known as spreading loss. Generally, sound levels from a point source will decrease by 6 dBA for each doubling of distance. Sound levels for a highway line source vary differently with distance because sound pressure waves propagate along the line and overlap at the point of measurement. A closely spaced, continuous fine of vehicles along a roadway becomes a line source and produces a 3 dBA decrease in sound level for each doubling of distance. However, experimental evidence has shown that where sound from a highway propagates close to "soft" ground (e.g., plowed farmland, grass, crops, etc.), a more suitable drop-off rate to use is not 3.0 dBA but rather 4.5 dBA per distance doubling (FHWA 2010). When sound is measured for distinct time intervals, the statistical distribution of the overall sound level during that period can be obtained. The Leq is the most common parameter associated with such measurements. The Leq metric is a single -number noise descriptor that represents the average sound level over a given period of time. For example, the L50 noise level is the level that is exceeded 50 percent of the time. This level is also the level that is exceeded 30 minutes in an hour. Similarly, the L02, L08 and L25 values are the noise levels that are exceeded 2, 8, and 25 percent of the time or 1, 5, and 15 minutes per hour. Other values typically noted during a noise survey are the Lmin and Lmax. These values represent the minimum and maximum root -mean -square noise levels obtained over the measurement period. page 14 of 15 noise management : roo►n acouslics : environmental impact www.45d8.com 45dB Acoustics, LLC Atascadero Drive -Through Coffee Shop Because community receptors are more sensitive to unwanted noise intrusion during the evening and at night, State law requires that, for planning purposes, an artificial dB increment be added to quiet -time noise levels in a 24-hour noise descriptor called the CNEL or Ldn. This increment is incorporated in the calculation of CNEL or Ldn, described earlier. 8.6 Evidence of Compliance Evidence of compliance shall consist of submittal of an acoustical analysis report, prepared under the supervision of a person experienced in the field of acoustical engineering, with the application for building permit. The report shall show topographical relationship of noise sources and dwelling site, identification of noise sources and their characteristics, predicted noise spectra at the exterior of the proposed dwelling structure considering present and future land usage, basis for the prediction (measured or obtained from published data), noise attenuation measures to be applied, and an analysis of the noise insulation effectiveness of the proposed construction showing that the prescribed interior noise level requirements are met. If interior allowable noise levels are met by requiring that windows be unopenable or closed, the design for the structure must also specify the means that will be employed to provide ventilation and cooling, if necessary, to provide a habitable interior environment. 1..

These regulations are of particular importance to drive-thru operators because the drive-thru is viewed as a source of noise. The noise originates both from the vehicles themselves and from the drive-thru communications system. This white paper addresses common questions related to sound from the communications system. Note: Because every site is different and each municipality has its own regulations, HMI; is unable to make specific recommendations for compliance or give any assurance that any particular system configuration will comply with any given regulations. Statements made in this paper should be taken as general guidelines, but to ensure compliance, the site planner should retain the services of a qualified acoustic consultant equipped to make the necessary measurements. In the drive-thru, the primary source of sound other than the vehicles is often the drive-thru communications system. Outbound audio includes the order taker's voice and any sound provided by the message repeater. The outbound audio is delivered by the speaker and must be loud enough to be clearly heard by the customer over the noise of the customer's vehicle, any local traffic and other ambient background noises in the area, However, if it is too loud, the sound can be objectionable to neighbors or even violate specific regulations. HME base stations are equipped with a feature known as Automatic Volume Control or "AVC" which can be used to reduce the outbound sound pressure level based on ambient noise. When AVC is active, the outbound level is reduced to a level that is 15 dB above the ambient noise level at the speaker post microphone, but it never increases the level above what would be heard with AVC turned off. This feature can considerably reduce the SPL during quiet periods and may help in satisfying local requirements. Sound levels are measured in units of dB SPL and usually include a frequency variable weight referred to as "A Weighting". For this reason, the units are frequently written as "dBA SPL" and that notation will be used throughout this paper. The sound pressure level from a speaker decreases as the distance away increases. However, it can be difficult to predict how much reduction will actually occur. For a single point sound source like an alarm bell hanging in air, the SPL drops approximately 6 dB every time the distance from the source doubles. Thus if one starts one foot away, the level will be 36 dB lower when one is 64 feet away. Unfortunately, speakers are neither single point sources nor are they hanging in air. Rather, speakers are mounted in a variety of different type enclosures. Further, the building, the ground and even other cars in proximity all effect the sound's direction and decay rate. All of this tends to make the sound more directional and the decay rate less predictable. This paper provides some "typical" measurements taken outdoors under specific circumstances. These measurements can be used as a guide for what levels might occur in a drive-through installation. These measurements were taken using "pink noise', a type of noise frequently used for acoustic testing, at levels simulating the loudest speech expected from an order taker. All typical measurements provided here were taken using the following equipment: • Base station: HME ION IQ set to factory default levels ■ Communicator: HME COM6000 ■ Speaker: HME SP10 • Speaker post: Texas Digital model 107150 DCO 5124/2010 Rev. 1.0 Drive-Thru Sound Levels The measurement environment was as follows: • Asphalt parking lot 50 ft from any building • Ambient background noise level: --47 dBA SPL • Nearest vehicle not part of measurement: 15 ft Initial measurements were taken with AVC off, no vehicle in front of the speaker post, and no other obstructions within at least 100 ft of the speaker. These are not "normal" conditions for a drive-thru, but they do yield one worst-case measurement. Under these conditions, the sound pressure level 1 foot in front of the speaker is 90 dBA SPL. At 17 feet, it drops down to a normal conversational level of 66 dBA SPL, but does not drop to 60 dBA until a distance of 55 feet. Figure 1 shows the loudness contours for both 60 dBA and 66 dBA levels. Since the primary concern is noise abatement at a distance, higher level contours are not shown. Loudness Contours o° 60 315` sem` 40 a 27a` go` 122z-5-t1`s5` 18Q= 55 dB 60 d6 Figure 1 — 5P10 SPL Contours With a vehicle parked in front of the speaker, the shape of the contour changes dramatically and depends on many factors including the height, size, shape, and angle of the vehicle. Because of the tremendous differences in vehicles, positioning, and lane construction, HMB cannot predict with any certainty the shape of the resulting SPL contours. However, generally, the shape flattens and the loudest sounds are found at angles to the front and rear of the vehicle with the front being louder. DCO 5/24/2010 Rev. 1.0 2 Drive-ihru Sound Levels AVC Operation AVC measures the ambient noise level in the drive-thru and adjusts the outbound level down so that it is never more than 15 dB above the ambient noise level. This is particularly useful at night when there is less traffic on surrounding streets and fewer cars in the drive-thru. It may also be useful in situations where the regulations do not specify specific sound pressure levels, but use terms like "reasonable" or "sufficient". Because AVC adjusts continuously, it ensures that the outbound level is high enough to be heard by the customer whatever the conditions may be. As an example, if the ambient noise level is 47 dBA, AVC will adjust the outbound level to approximately 62 dBA at a position about 1 ft from the speaker. Given this condition, the SPL will be below the ambient noise level less than 20 ft away from the post. Since AVC adjusts based on the noise level measured at the speaker post, a noisy vehicle will drive the outbound level up. Thus, the use of AVC will not guarantee that the SPL is below any particular level for all vehicles or conditions. However, it will keep the outbound level from becoming excessively loud. Guidelines HME cannot make specific recommendations, but here are some general things that can be done to minimize issues: • Place the speaker post where vehicles can get close to it. This allows the outbound level to be kept to a minimum. • Use brick or concrete walls to isolate the installation from adjacent residences. These walls make good barriers, but must be high enough that sounds do not easily go over them. • Adjust the outbound level to the minimum necessary to be clearly heard by customers • Use AVC in situations where noise abatement is an issue to further reduce outbound levels during quiet periods. Don't • Face the speaker post toward busy streets. This increases the ambient noise level and makes it necessary to use higher outbound levels. • Place the speaker post on a curve in the lane. Curves force vehicles to be further away from the post, which results in higher outbound level requirements and makes it difficult for order takers to hear customers. • Face the speaker post or the drive-thru lane at adjacent residences. Remember that the highest sound levels are likely to be directly opposite the post and off the front of vehicles: • Turn the outbound level up higher than necessary. ■ Rely on vegetation to reduce sounds. Plants have rather limited impact on sound levels. DCO 5/24/2010 Rev. 1.0 Customer Driven 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 ost; Distance from the Speaker (Feet) SPL (dBA) I 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 or 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 6o 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.

Yes, Mr. Newton is frustrated & feels like there is a lot of focus on his two parcels, it feels like he's been singled out. His consultant team has over 125 years of experience & none of us have seen this level of focus on specific parcel either. While it is no secret that Mr. Newton would like to permit mini -storage on his site, he has also discussed other permitted uses with staff, but has found no support for any of those uses either. In addition, Mr. Newton has been told that he cannot rezone his parcel due to the "pending" General Plan Update which is creating an inability for him to exercise his property rights. Mr. Newton bought his parcels based on the zoning. He wanted to develop them into a source of income. We need your help. You are smart people, certainly you see the dilemma. All Mr. Newton wants to know is "what is the right use"? This site is home to other failed proposals that did not meet the City's expectations either, so it begs the question that no one seems to be able to answer, what can be approved on this site? Despite numerous meetings, we only hear statements like "partner with developers who know haw to get a project approved" or sell the parcel, no actual input that could result in an approvable project. We'd like to request that rather than make a revision now that might not even matter after the General Plan Amendment, that you just wait on taking any action for zoning on the P zoned parcels for now. Maybe Mr. Newton's parcels won't even be P zoned after the General Plan Amendment. The timing for this zone revision just feels forced; certainly, there is no imminent threat to the City that would make this change necessary. In the meantime, Mr. Newton has been keeping communication open with the City in hopes that he can deliver a project that is a win for him & the community. Could you hit the pause button on any action & wait until the General Plan Update occurs? Thank you for your consideration.
