The approximately 10.4-acre previously graded project site is currently undeveloped. The project would construct a 120-bed behavioral health facility in a 92,349-square-foot building. This report discusses potential noise impacts from the construction and operation of the project. As part of this assessment, noise levels due to vehicle traffic were calculated and evaluated against City of Chula Vista (City) noise and land use compatibility guidelines. In addition to compatibility, the potential for noise to impact adjacent uses from future on-site sources and construction activity was assessed. A summary of the findings is provided below. Construction Noise Construction activity is regulated by the Chula Vista Municipal Code (CVMC), which prohibits construction and building work in residential zones that would cause noises disturbing to the peace, comfort, and quiet enjoyment of property of any person residing or working in the vicinity between the hours of 10:00 p.m. and 7:00 a.m., Monday through Friday, and between the hours of 10:00 p.m. and 8:00 a.m., Saturday and Sunday. Noise associated with the grading, building, and paving for the project would potentially result in short-term impacts to surrounding residential properties. Construction noise levels would range from 56 to 68 A-weighted decibels equivalent noise level [dB(A) Leq] at the adjacent properties. Although the existing adjacent residences would be exposed to construction noise levels that could be heard above ambient conditions, the exposure would be temporary. Additionally, construction activities would occur only during the hours specified in the CVMC. Because construction activities associated with the project would comply with the applicable regulation for construction, temporary increases in noise levels from construction activities would be less than significant. Traffic Noise On-site Traffic Noise The main sources of vehicle traffic noise at the project site are Hunte Parkway, Fenton Street, Showroom Place, Yosemite Drive, and River Rock Road. Exterior noise levels were modeled at the project site to determine compatibility with City standards. The applicable standards for noise sensitive uses such as the project are an exterior noise level of 65 community noise equivalent level (CNEL) and an interior noise level of 50 CNEL. The project’s exterior useable spaces include the six proposed exterior activity areas and the staff outdoor area. As calculated in this analysis, noise levels at the staff outdoor area and the exterior activity areas would range from 31 to 45 CNEL. Noise levels at the exterior use areas would be compatible with the City’s standard of 65 CNEL. Noise Analysis Eastlake Behavioral Health Hospital Project Page 2 Exterior noise levels at the building façade are projected to range from 38 to 51 CNEL. The interior noise level standard is 50 CNEL. According to the Federal Highway Administration (FHWA), when windows are open, standard construction techniques provide a 10 dB exterior-to-interior noise level reduction (FHWA 2011). Based on these standards, interior noise levels would be reduced to 41 CNEL or less. Therefore, impacts related to on-site traffic noise would be less than significant. Off-site Traffic Noise The additional vehicle trips associated with the project would increase noise levels on nearby roadways. A noise increase of 3 dB or more would be considered significant because 3 dB is the level at which an increase in noise is perceptible to a person. As calculated in this analysis, direct off-site noise level increases due to the project would be 1 dB or less. Therefore, direct off-site noise impacts associated with the project would be less than significant. The total horizon year traffic volumes (year 2035) plus project traffic would increase over the existing condition, ranging from less than 1 dB to 5 dB. However, the project’s contribution to the increase over ambient noise levels would be 1 dB or less. Therefore, the project would result in a less than cumulatively considerable off-site noise level increase, and cumulative traffic noise impacts associated with the project would be less than significant. On-site Generated Noise The primary noise sources on-site would be rooftop heating, ventilating, and air conditioning (HVAC) equipment, an emergency generator, and truck deliveries and loading dock activities. For a worst-case analysis, property line noise levels due to all noise sources were modeled and compared to the most restrictive nighttime CVMC limits. Typical noise levels without the continuous operation of the emergency generator were also modeled. As calculated in this analysis, on-site generated noise levels at the residential property lines would range from 35 to 45 dB(A) Leq with the generator running and 34 to 43 dB(A) Leq without the generator running. Noise levels would not exceed the single family residential CVMC limits. At the commercial property lines, noise levels would range from 40 to 54 dB(A) Leq with the generator running and 39 to 51 dB(A) Leq without the generator running. Noise levels would not exceed the commercial CVMC limits. Therefore, impacts related to on-site generated noise would be less than significant. Noise Analysis Eastlake Behavioral Health Hospital Project Page 3 1.0 Introduction 1.1 Project Description The Eastlake Behavioral Health Hospital Project (project) is located at 830 and 831 Showroom Place in the city of Chula Vista, California, north Fenton Street, west of Hunte Parkway, and east of Lane Avenue. The project site is a previously graded pad in the EastLake Business Center Specific Plan area and is bounded by single-family residential uses to the north and southeast, commercial uses to the west and south. Specifically, the project site sits adjacent to The District at Eastlake, which is nearly fully developed with commercial uses and parking. The project site is surrounded by commercial uses such as restaurants, and family-oriented businesses, providing play areas and classes for adults and children. A number of these businesses include Eastlake Speed Circuit, Crunch Select Gym, Ninja Factory, Sky Zone, Play City, Pride Martial Arts, Kid Ventures, Sylvan Learning Center, Little Artists, DanceArts, and Floaties Swim School. The Eastlake Montessori School is also located within The District at Eastlake. The project site is a previously graded pad in the Eastlake Business Center and is bounded by single-family residential uses to the north and southeast, commercial uses to the west and south, and aA boat and recreational vehicle storage lot to the south. The approximately 10.4-acre project site is currently undeveloped. Figure 1 shows the regional location of the project. Figure 2 shows an aerial photograph of the project and vicinity. The project would construct a 120-bed behavioral health facility in a 92,349-square-foot building with exterior activity areas and a staff outdoor area. Figure 3 shows the proposed site plan. 1.2 Fundamentals of Noise Sound levels are described in units called the decibel (dB). Decibels are measured on a logarithmic scale that quantifies sound intensity in a manner similar to the Richter scale used for earthquake magnitudes. Thus, a doubling of the energy of a noise source, such as doubling of traffic volume, would increase the noise level by 3 dB; a halving of the energy would result in a 3 dB decrease. However, human perception of noise has no simple correlation with acoustical energy. A change in noise levels is generally perceived as follows: 3 A-weighted dB [dB(A)] barely perceptible, 5 dB(A) readily perceptible, and 10 dB(A) perceived as a doubling or halving of noise (California Department of Transportation 2013). In technical terms, sound levels are described as either a “sound power level” or a “sound pressure level,” which while commonly confused, are two distinct characteristics of sound. Both share the same unit of measure, the dB. However, sound power, expressed as Lpw, is the energy converted into sound by the source. As sound energy travels through the air, it creates a sound wave that exerts pressure on receivers such as an eardrum or microphone, the sound pressure level. Sound measurement instruments only measure sound pressure, and limits used in standards are generally sound pressure levels.

To accommodate this phenomenon, the A-scale, which approximates the frequency response of the average young ear when listening to most ordinary everyday sounds, was devised. When people make relative judgments of the loudness or annoyance of a sound, their judgments correlate well with the A-scale sound levels of those sounds. Therefore, the “A-weighted” noise scale is used for measurements and standards involving the human perception of noise. Noise levels using A-weighted measurements are designated with the notation dB(A). 1.2.1 Descriptors The impact of noise is not a function of loudness alone. The time of day when noise occurs and the duration of the noise are also important. In addition, most noise that lasts for more than a few seconds is variable in its intensity. Consequently, a variety of noise descriptors has been developed. The noise descriptors used for this study are the equivalent noise level (Leq) and the community noise equivalent level (CNEL). The Leq is the equivalent steady-state noise level in a stated period of time that is calculated by averaging the acoustic energy over a time period; when no period is specified, a 1-hour period is assumed. The CNEL is a 24-hour equivalent sound level. The CNEL calculation applies an additional 5 dB(A) penalty to noise occurring during evening hours, between 7:00 p.m. and 10:00 p.m., and a 10 dB(A) penalty is added to noise occurring during the night, between 10:00 p.m. and 7:00 a.m. These increases for certain times are intended to account for the added sensitivity of humans to noise during the evening and night. 1.2.2 Propagation Sound from a localized source (approximating a “point” source) radiates uniformly outward as it travels away from the source in a spherical pattern, known as geometric spreading. The sound level decreases or drops off at a rate of 6 dB(A) for each doubling of the distance. Traffic noise is not a single, stationary point source of sound. The movement of vehicles makes the source of the sound appear to emanate from a line (line source) rather than a point when viewed over some time interval. The drop-off rate for a line source is 3 dB(A) for each doubling of distance. The propagation of noise is also affected by the intervening ground, known as ground absorption. A hard site (such as parking lots or smooth bodies of water) receives no additional ground attenuation, and the changes in noise levels with distance (drop-off rate) are simply the geometric spreading of the source. A soft site (such as soft dirt, grass, or scattered bushes and trees) provides an additional ground attenuation value of 1.5 dB(A) per doubling of distance. Thus, a point source over a soft site would drop off at 7.5 dB(A) per doubling of distance. Noise Analysis Eastlake Behavioral Health Hospital Project Page 8 2.0 Applicable Noise Standards 2.1 General Plan 2.1.1 Noise/Land Use Compatibility The Environmental Element of the City of Chula Vista (City) General Plan contains applicable noise/land use compatibility guidelines, which are shown in Table 1. As shown, noise sensitive uses such as the project are considered compatible when located in areas where exterior noise levels are 65 CNEL or less (City of Chula Vista 2005). For the project, the City applies this exterior noise level standard at the proposed exterior use areas which include the six proposed exterior activity areas and the staff outdoor area (see Figure 3). Table 1 Exterior Land Use/Noise Compatibility Guidelines Land Use CNEL 50 55 60 65 70 75 Residential Schools, Libraries, Daycare Facilities, Convalescent Homes, Outdoor Use Areas, and Other Similar Uses Considered Noise Sensitive Neighborhood Parks, Playgrounds Offices and Professional Places of Worship (excluding outdoor use areas) Golf Courses Retail and Wholesale Commercial, Restaurants, Movie Theaters Industrial, Manufacturing 2.1.2 Policies The following policies from the City General Plan are relevant to this noise analysis: EE 21.1 Apply the exterior land use-noise compatibility guidelines contained in Table 9-2 of this Environmental Element to new development where applicable and in light of project-specific considerations. (Note: Table 9-2 of the Environmental Element is Table 1 of this report.) EE 21.2 Where applicable, the assessment and mitigation of interior noise levels shall adhere to the applicable requirements of the California Building Code with local amendments and other applicable established City standards. EE 21.3 Promote the use of available technologies in building construction to improve noise attenuation capacities. EE 22.5 Require projects to construct appropriate mitigation measures in order to attenuate existing and projected traffic noise levels in accordance with applicable standards, including the exterior land use/noise compatibility guidelines contained in Table 9-2 of this Environmental Element. Noise Analysis Eastlake Behavioral Health Hospital Project Page 9 2.2 City of Chula Vista Noise Control Ordinance 2.2.1 On-site Generated Noise The Noise Control Ordinance (Chula Vista Municipal Code [CVMC] Chapter 19.68) establishes noise criteria to prevent noise and vibration that may jeopardize the health or welfare of the City’s citizens or degrade their quality of life. CVMC Section 19.68.030 defines exterior noise standards for various receiving land uses. The noise standards are not to be exceeded at the portion of a property used for a particular land use. For nuisance noise, the noise standards cannot be exceeded at any time. Examples of nuisance noise provided in the Noise Control Ordinance include pets in residential neighborhoods, private parties of limited duration, sound amplifiers and musical instruments, and any activities in commercial areas other than permitted uses. For environmental noise, the Leq in any one hour cannot exceed the noise standards. These standards are shown in Table 2. The noise standards in Table 2 do not apply to construction activities. Table 2 City of Chula Vista Exterior Noise Limits Receiving Land Use Category Noise Level [dB(A)]1,2,3 10:00 p.m. to 7:00 a.m. (Weekdays) 7:00 a.m. to 10:00 p.m. (Weekdays) 10:00 p.m. to 8:00 a.m. (Weekends) 8:00 a.m. to 10:00 p.m. (Weekends) All residential (except multiple dwelling) 45 55 Multiple dwelling residential 50 60 Commercial 60 65 Light Industry – I-R and I-L zone 70 70 Heavy Industry – I zone 80 80 SOURCE: CVMC Section 19.68.030 1 Environmental Noise – One-hour equivalent in any hour; Nuisance Noise – not to be exceeded any time 2 According to CVMC Section 19,68,030(b)(2), if the alleged offensive noise contains a steady, audible sound such as a whine, screech or hum, or contains a repetitive impulsive noise such as hammering or riveting, the standard limits shall be reduced by 5 decibels. 3 If the measured ambient level, measured when the alleged noise violation source is not operating, exceeds the standard noise limit, the allowable noise exposure standard shall be the ambient noise level. Section 19.68.060(A) states that “Warning devices necessary for the protection of public safety, as, for example, police, fire and ambulance sirens, and train horns, are exempted from the provisions of this title.” 2.2.2 Construction Noise Construction noise is regulated by CVMC Section 17.24.040, which prohibits construction and building work in residential zones that would cause noises disturbing to the peace, comfort, and quiet enjoyment of property of any person residing or working in the vicinity between the hours of 10:00 p.m. and 7:00 a.m., Monday through Friday, and between the hours of 10:00 p.m. and 8:00 a.m., Saturday and Sunday. Noise Analysis Eastlake Behavioral Health Hospital Project Page 10 2.3 California Green Building Standards Code – Environmental Comfort For nonresidential structures, Title 24, Chapter 12, Section 1207.5 refers to 2016 California Green Building Standards, Chapter 5 – Nonresidential Mandatory Measures, Division 5.5 – Environmental Quality, Section 5.507 – Environmental Comfort, Subsection 5.507.4 – Acoustical Control. Pursuant to these standards, all nonresidential building construction shall employ building assemblies and components that achieve a composite sound transmission class rating of at least 50 or shall otherwise demonstrate that exterior noise shall not result in interior noise environment where noise levels exceed 50 A-weighted equivalent decibels [dB(A) Leq] in occupied areas during any hour of operation (24 California Code of Regulations 1207.5 2016). 3.0 Existing Conditions Existing noise levels in the vicinity of the project site were measured on March 14, 2019, using one Larson-Davis Model LxT, Type 1 Integrating Sound Level Meter, serial number 3827. The following parameters were used: Filter: A-weighted Response: Slow Interval Period 1 minute Time History Period: 5 seconds The meter was calibrated before and after each measurement. The meter was set 5 feet above the ground level for each measurement. Noise measurements were taken to obtain typical ambient noise levels at the project site and in the vicinity. The weather was sunny and warm with a slight breeze, zero to two miles per hour on average. Three 15-minute measurements were taken, as described below. The measurement locations are shown on Figure 4, and detailed data is contained in Attachment 1. Measurement 1 was located at the northeast corner of the project site, approximately 400 feet west of Hunte Parkway and 200 feet northwest of Yosemite Drive. Noise levels were measured for 15 minutes. The main noise source at this location was vehicle traffic Yosemite Drive. Secondary sources of noise included activities at Eastlake Middle School, airplanes, and bird vocalizations. Vehicle traffic on Yosemite Drive was counted during the measurement period. The average measured noise level was 52.4 dB(A) Leq. Measurement 2 was located near the northern project boundary, approximately 130 feet south of River Rock Road. Noise levels were measured for 15 minutes. The main noise source at this location was vehicle traffic on River Rock Road and airplanes. Secondary sources of noise included activities at Eastlake Middle School and bird vocalizations.

Diesel engine-driven trucks also would bring materials to the site and remove the soils from excavation. Construction equipment with a diesel engine typically generates maximum noise levels from 70 and 95 dB(A) maximum sound level (Lmax) at a distance of 50 feet (Federal Highway Administration [FHWA] 2006). Table 5 summarizes typical construction equipment noise levels.

During excavation, grading, and paving operations, equipment moves to different locations and goes through varying load cycles, and there are breaks for the operators and for non-equipment tasks, such as measurement. Average construction noise levels were calculated for the simultaneous operation of three common pieces of construction equipment: backhoe, excavator, and loader. The usage factors were applied to the maximum noise level at 50 feet for each piece of equipment, and then noise levels were added logarithmically. Hourly average noise levels would be approximately 85 dB(A) Leq at 50 feet from the center of construction activity when assessing three pieces of common construction equipment working simultaneously. Noise Analysis Eastlake Behavioral Health Hospital Project Page 14 4.2 Traffic Noise Analysis 4.2.1 On-Site Traffic Noise Noise generated by future traffic was modeled using SoundPLAN Essential, version 4.1. The SoundPLAN program (Navcon Engineering 2015) uses the FHWA Traffic Noise Model algorithms and reference levels to calculate noise levels at selected receiver locations. The model uses various input parameters, such as projected hourly average traffic rates; vehicle mix, distribution, and speed; roadway lengths and gradients; distances between sources, barriers, and receivers; and shielding provided by intervening terrain, barriers, and structures. Receivers, roadways, and barriers were input into the model using three- dimensional coordinates. The locations of future buildings were obtained from project plans and drawings. Noise levels due to vehicle traffic on the roadways nearest to the project site where modeled. For the purpose of traffic noise compatibility analysis, the noisiest condition is represented as the maximum level of service (LOS) C traffic volume. This condition represents a condition where the maximum number of vehicles are using the roadway at the maximum speed. LOS A and B categories allow full travel speed but do not have as many vehicles, while LOS E and F have a greater number of vehicles, but due to the traffic volume travel at reduced speeds, thus generating less noise. Hunte Parkway is a 4-lane major road with a maximum LOS C capacity of 33,800 average daily traffic (ADT), and Fenton Street is a Class I Collector with a maximum LOS C capacity of 24,800 ADT (City of Chula Vista 2005). Showroom Place, Yosemite Drive, and River Rock Road are not circulation element roadways. Showroom Place is a cul-de-sac that ends at the project site. The total project trip generation of 2,400 ADT was used to model vehicle traffic noise from Showroom Place (Linscott, Law & Greenspan, Engineers 2019). Yosemite Drive and River Rock Road are residential streets. The residential street design volume of 1,200 ADT was used to model vehicle traffic noise from these two roads (City of Chula Vista 2012). A standard vehicle classification mix of 95 percent automobiles, 2 percent medium trucks, 1 percent heavy trucks, 1 percent buses, and 1 percent motorcycles was modeled. Table 6 summarizes the traffic volumes and vehicle classification mixes for the modeled roadways.

Traffic noise levels were calculated at 50 feet from the centerline of the affected roadways to determine the noise level increase associated with the project. The model uses various input parameters, such as traffic volumes; vehicle mix, distribution, and speed. The roadways included in the traffic impact analysis are Otay Lakes Road, Eastlake Parkway, Fenton Street, and Hunte Parkway. Traffic noise levels were calculated based on the total average daily traffic volumes on each roadway segment. For modeling purposes, “hard” ground conditions were used for the analysis of future conditions, since a majority of the project area is paved and the hard site provides the most conservative impact assessment. Existing and future (year 2035) traffic volumes with and without the project were obtained from the project traffic impact analysis (Linscott, Law & Greenspan, Engineers 2019). Table 7 summarizes the future traffic volumes for the area roadway segments. Modeled noise levels do not account for shielding provided by intervening barriers and structures.

These sources would have the potential to produce noise in excess of City limits (see Table 2). Noise Analysis Eastlake Behavioral Health Hospital Project Page 16 Noise levels due to on-site sources were modeled using SoundPLAN. The SoundPLAN program models noise propagation following the International Organization for Standardization method ISO 9613-2 – Acoustics, Attenuation of Sound during Propagation Outdoors. The model calculates noise levels at selected receiver locations using input parameter estimates such as total noise generated by each noise source; distances between sources, barriers, and receivers; and shielding provided by intervening structures. 4.3.1 Heating, Ventilation, and Air Conditioning Equipment The HVAC equipment would be located at various locations on the roof of the proposed building. It is not known at this time which manufacturer, brand, or model of unit or units will be selected for use in the project. Typically, a capacity of 1-ton per 340 square feet would be required for large office buildings. This ratio was used to determine the total HVAC capacity required for the project. Based on this ratio, the 92,349-square-foot building would require a capacity of approximately 272 tons. As a conservative analysis, thirty 10-ton units, for a total capacity of 300 tons, were modeled on the roof of the proposed building. Based on review of manufacturer specifications for a sample unit (Trane Model T/YSCE120ED), a representative noise level for a 10-ton unit would be a sound power level of 79 dB. Noise specifications are contained in Attachment 2. All units were modeled at full capacity during the daytime and nighttime hours. 4.3.2 Emergency Generator The emergency generator would be located on the west side of the proposed building within a 16-foot concrete masonry unit wall. The specifications for the Cat C27 diesel generator set that would be used are contained in Attachment 3. Based on these noise specifications, the generator produces a noise level of 75 dB(A) at 23 feet. Continuous operation of the generator would only occur during emergency situations when the facility loses power from the main power grid. However, the generator would be operated periodically for routine testing and maintenance. Property line noise levels were modeled with and without operation of the generator. Modeled noise levels take into account to 16-foot wall that would surround the generator. The generator would also be equipped with a sound blanket, however, noise reduction due to this feature were not taken into account. 4.3.3 Delivery Trucks Two loading docks would be located on the west side of the proposed building. In order to evaluate the truck delivery noise impacts, the analysis utilized reference noise level measurements taken at an Albertson’s Shopping Center in San Diego, California in 2011. The measurements include truck drive-by noise, truck loading/unloading, and truck engine noise. The unmitigated exterior noise levels for truck drive-by noise and truck engine noise were measured at 66.5 dB(A) Leq at a distance of 25 feet from the loading dock. This is equivalent to a sound power level of 92.1 dB(A). Noise Analysis Eastlake Behavioral Health Hospital Project Page 17 The on-site maneuvering associated with the delivery trucks consists of the truck entering the site and backing into the loading dock, idling, loading and unloading, and leaving the site. It is anticipated that the project would receive three to five deliveries per day. Because there are two loading docks, the simultaneous operation of two delivery trucks was modeled. It was assumed that it would take 5 minutes for a truck to enter and leave the project site. During the loading/unloading of the truck, the engine can only idle for a maximum of 5 minutes in compliance with state regulations for air quality. To calculate property line noise levels, trucks were modeled as a line source while entering and leaving the site, and as a point source at each loading dock while idling. 5.0 Future Acoustical Environment and Impacts 5.1 Construction Noise Noise associated with the grading, building, and paving for the project would potentially result in short-term impacts to surrounding residential properties. There are residential uses located north and southeast of the project site. A variety of noise-generating equipment would be used during the construction phase of the project, such as excavators, backhoes, front-end loaders, and concrete saws, along with others. The exact number and pieces of construction equipment required are not known at this time. As discussed, average construction noise levels were calculated. Based on this analysis, hourly average noise levels would be approximately 83 dB(A) Leq at 50 feet from the center of construction activity when assessing three pieces of common construction equipment working simultaneously. Construction noise is considered a point source and would attenuate at approximately 6 dB(A) for every doubling of distance. To reflect the nature of grading and construction activities, equipment was modeled as an area source distributed over the project footprint. Noise levels were modeled at a series of 20 receivers located at the adjacent uses. The results are summarized in Table 8. Modeled receiver locations and construction noise contours are shown in Figure 5. SoundPLAN data is contained in Attachment 4. As shown, construction noise levels would range from 56 to 68 dB(A) Leq at the adjacent uses. Although the existing adjacent residences would be exposed to construction noise levels that could be heard above ambient conditions, the exposure would be temporary. Additionally, construction activities would occur between the hours of 7:00 a.m. and 10:00 p.m. Monday through Friday, and between the hours of 8:00 a.m. and 10:00 p.m. Saturday and Sunday, as specified in the City Construction Noise Ordinance. Because construction activities associated with the project would comply with the applicable regulation for construction, temporary increases in noise levels from construction activities would be less than significant.

Noise level contours were modeled at the first-floor level. These contours take into account shielding provided by the proposed building and grading, but do not taken in to account shielding due to adjacent buildings and are therefore conservative. Future vehicle traffic noise-level contours are shown in Figure 6. SoundPLAN data are contained in Attachment 5. As discussed in Section 2.1, noise sensitive uses such as the project are considered compatible when located in areas where exterior noise levels are 65 CNEL or less. This standard is applicable at exterior use areas that include the six proposed exterior activity areas and the staff outdoor area. To refine the noise analysis and determine noise levels at exterior use areas and the building façade, exterior noise levels were calculated at a series of receiver locations at the staff outdoor area (Receiver 1), the exterior activity areas (Receivers 2 through 7), and around the proposed building (Receivers 8 through 15). Modeled receiver locations are shown in Figure 6. Table 9 summarizes the projected future noise levels at the 15 modeled receivers.

Noise levels at the exterior use areas would be compatible with the City’s standard of 65 CNEL. Exterior noise levels at the building façade are projected to range from 38 to 51 CNEL. The interior noise level standard is 50 CNEL. When windows are open, standard construction techniques provide a 10 dB exterior-to-interior noise level reduction (FHWA 2011). Based on these standards, interior noise levels would be reduced to 41 CNEL or less. Therefore, impacts related to on-site traffic noise would be less than significant. 5.2.2 Off-site Traffic Noise The project would increase traffic volumes on local roadways. However, the project would not substantially alter the vehicle classifications mix on local or regional roadways, nor would the project alter the speed on an existing roadway or create a new roadway. Thus, the primary factor affecting off-site noise levels would be increased traffic volumes. While changes in noise levels would occur along any roadway where project-related traffic occurs, for noise assessment purposes, noise level increases are assumed to be greatest nearest the project site, as this location would represent the greatest concentration of project-related traffic. Traffic noise increases attributable to the project were assessed against a significance threshold of 3 dB, which is the level at which an increase in noise is considered to be barely perceptible (Caltrans 2013). Table 10 presents a conservative assessment of traffic noise levels based on the existing, existing plus project, horizon year (2035), and horizon year (2035) plus project noise levels generated by traffic. Table 10 also summarizes the direct and cumulative traffic noise level increases due to the project. Noise level calculations are contained in Attachment 6. Noise Analysis Eastlake Behavioral Health Hospital Project Page 22 Table 10 Traffic Noise Level with and without Project and Ambient Noise Increases Roadway Segment Existing Existing + Project Direct Increase Year 2035 Year 2035 + Project Direct Increase Cumulative Increase Over Existing Otay Lakes Road State Route 125 Northbound Ramps to Eastlake Parkway 77 77 <1 78 78 <1 1 Eastlake Parkway to Lane Avenue 75 75 <1 75 76 1 1 Lane Avenue to Fenton Street 73 74 1 75 75 <1 2 Fenton Street to Hunte Parkway 73 74 1 75 75 <1 2 East Hunte Parkway 70 70 <1 75 75 <1 5 Eastlake Parkway Fenton Street to Otay Lakes Road 72 72 <1 72 73 1 1 Fenton Street Lane Avenue to Showroom Place 66 66 <1 68 68 <1 2 Showroom Place to Otay Lakes Road 65 66 1 67 68 1 3 Hunte Parkway Otay Lakes Road to Clubhouse Drive 71 71 <1 72 72 <1 1 As shown in Table 10, direct off-site noise level increases due to the project would be 1 dB or less. Therefore, direct off-site noise impacts associated with the project would be less than significant. Similar to direct traffic noise impacts, a cumulative traffic noise impact occurs when the noise level would exceed the applicable standard and a substantial noise level increase compared to existing noise occurs. As shown, the total horizon year (year 2035) plus project increase over the existing condition would range from 1 dB to 5 dB. However, the project’s contribution to the increase over ambient noise levels would be 1 dB or less. Therefore, the project would result in a less than cumulatively considerable off-site noise level increase, and cumulative traffic noise impacts associated with the project would be less than significant. 5.3 On-site Generated Noise The primary noise sources on-site would be HVAC equipment, an emergency generator, and truck deliveries and loading dock activities. Using the on-site noise source parameters discussed in Section 4.3, noise levels were modeled at a series of 20 receivers located at the property line. For a worst-case analysis, noise levels due to all noise sources were modeled and compared to the most restrictive nighttime CVMC limits. Typical noise levels without the continuous operation of the emergency generator were also modeled. Modeled receivers and the locations of the on-site noise sources are shown in Figures 7a and 7b. Figure 7a shows the on-site generated noise contours with operation of the emergency generator, and Figure 7b shows the noise contours without operation of the emergency generator. Modeled data is included in Attachment 7. Future projected noise levels are summarized in Table 11.

Noise levels would not exceed the single-family residential CVMC limits. At the commercial property lines, noise levels would range from 40 to 54 dB(A) Leq with the generator running and 39 to 51 without the generator running. Noise levels would not exceed the commercial CVMC limits. Therefore, impacts related to on-site generated noise would be less than significant. 6.0 Conclusions 6.1 Construction Noise As shown in Table 8, construction noise levels would range from 56 to 68 dB(A) Leq at the adjacent property lines. Although the existing adjacent residences would be exposed to construction noise levels that could be heard above ambient conditions, the exposure would be temporary. Additionally, construction activities would occur between the hours of 7:00 a.m. and 10:00 p.m. Monday through Friday, and between the hours of 8:00 a.m. and 10:00 p.m. Saturday and Sunday, as specified in the CVMC. Because construction activities associated with the project would comply with the applicable regulation for construction, temporary increases in noise levels from construction activities would be less than significant. Noise Analysis Eastlake Behavioral Health Hospital Project Page 26 6.2 Traffic Noise 6.2.1 On-site Traffic Noise The main sources of vehicle traffic noise at the project site are Hunte Parkway, Fenton Street, Showroom Place, Yosemite Drive, and River Rock Road. The exterior noise level standard for noise sensitive uses such as the project is 65 CNEL. This standard is applicable at exterior use areas which include the six proposed exterior activity areas and the staff outdoor area. As shown in Table 9, noise levels at the staff outdoor area and the exterior activity areas would range from 31 to 45 CNEL. Noise levels at the exterior use areas would be compatible with the City’s standard of 65 CNEL. Exterior noise levels at the building façade are projected to range from 38 to 51 CNEL. The interior noise level standard is 50 CNEL. When windows are open, standard construction techniques provide a 10 dB exterior-to-interior noise level reduction (FHWA 2011). Based on these standards, interior noise levels would be reduced to 41 CNEL or less. Therefore, impacts related to on-site traffic noise would be less than significant. 6.2.2 Off-site Traffic Noise The additional vehicle trips associated with the project would increase noise levels on nearby roadways. A noise increase of 3 dB or more would be considered significant because 3 dB is the level at which an increase in noise is perceptible to a person. As shown in Table 10, direct off-site noise level increases due to the project would be 1 dB or less. Therefore, direct off-site noise impacts associated with the project would be less than significant. The total horizon year (year 2035) plus project increase over the existing condition would range from less than 1 dB to 5 dB. However, the project’s contribution to the increase over ambient noise levels would be 1 dB or less. Therefore, the project would result in a less than cumulatively considerable off-site noise level increase, and cumulative traffic noise impacts associated with the project would be less than significant. 6.3 On-site Generated Noise The primary noise sources on-site would be HVAC equipment, an emergency generator, and truck deliveries and loading dock activities. For a worst-case analysis, property line noise levels due to all noise sources were modeled and compared to the most restrictive nighttime CVMC limits. Typical noise levels without the continuous operation of the emergency generator were also modeled. As shown in Table 11, property line noise levels with and without operation of the emergency generator are not projected to exceed the applicable residential and commercial CVMC limits. Therefore, impacts related to on-site generated noise would be less than significant.
