Dharma Truong, Kimley-Horn and Associates, Inc. Date: August 2026 Subject: 1515 Walnut Grove Avenue Project, Rosemead, CA – Noise and Vibration Analysis Purpose The purpose of this memorandum is to assess the potential impacts due to noise and vibration associated with construction and operation of the 1515 Walnut Grove Avenue Project (Project or proposed Project), proposed to be located in the City of Rosemead (City), California. Project Location The Project would be developed on approximately 9.28 acres (404,146 square feet) (Project Site). The Project Site is comprised of one parcel (Los Angeles County Assessor’s Parcel Number [APN] 5279-027- 001). The Project Site is currently developed with two vacant buildings built in 1982 that were operated by Southern California Edison (SCE). The Project Site includes a 249,701-sf office building; an 18,314-sf detached central plant building containing a chiller room, emergency generator room, break room, office, restroom, fan room, boiler room, transformer room, and cooling towers; and a surface parking lot. A sewer lift station is also located in the parking lot southwest of the office building. The office building and central plant are currently vacant; however, the cooling systems within the central plant remain functional, but not operational. There is minimal landscaping on the Project Site, limited to ornamental trees and shrubs. The Project Site is surrounded by office development, commercial uses, and surface parking to the north; Walnut Grove Avenue and the Whittier Narrows Golf Course to the east; surface parking and the University of the West to the south; and residential development to the west. Unincorporated areas of Los Angeles County (County) border the Project Site to the east of Walnut Grove Avenue and to the west along the Project Site’s western boundary. Please refer to Figure 1: Regional Location Map and Figure 2: Local Vicinity Map. Regional vehicle access to the Project Site is provided by the State Route (SR) 60 and SR 164 (Rosemead Boulevard), located approximately 0.54 miles (2,894 feet) south and 1.04 miles (5,491 feet) east, respectively. Local vehicle access to the Project Site is provided via Rush Street, located approximately 0.20 miles (1,040 feet) north of the Project Site and Walnut Grove Avenue directly east of the Project Site. The Project Site is located in proximity to several transit options. The Project Site is located approximately 0.25 miles (1,342 feet) south of the Los Angeles County Metropolitan Transportation Authority (Metro) 287 bus stop. The Project Site is also served by the Montebello Transit 20 San Gabriel bus line, located approximately 0.33 miles (1,772 feet) to the south of the site.

Of the 27 buildings, 13 buildings would be dedicated to 83 tandem townhomes and 14 buildings would be dedicated to 108 row townhomes. The Project would comprise a total of 191 dwelling units. Each unit would include two garage spaces. The Project would provide 104 double-striped guest parking spaces. Additionally, the Project would provide public right of way improvements such as a 1,253 square foot of parkway and a 3,000 square foot improved sidewalk along Walnut Grove Avenue. The Project would provide 126,015 square foot of open space for residents, including 75,004 square foot of landscaping, 43,597 square foot of hardscape, 3,831 square foot of decomposed granite, 972 SF playground, 1,933 square foot pool, and 160 square foot spa. A dog park, bench seating, and picnic tables would be located in the northeast corner of the Project Site. On the southeast corner of the Project Site, the Project would include a bioretention basin and recreation center with a restroom facility, community pool, group spa, cabanas, gas barbeque grills, and a sundeck. A community garden with dwarf citrus trees would be located in the southwest corner of the Project Site. A central garden court with a shade structure, picnic tables, open lawn play area, and tot-lot with play equipment and rubber surfacing would be located between buildings 13, 14, 17, and 18. Project construction is anticipated to occur in one phase, lasting approximately 34 months, beginning as early as October 2026 and ending as early as August 2029. Project construction and architectural coating would occur over one phase. Construction would be consistent with the City of Rosemead Municipal Code (RMC) Chapter 8.36, including, without limitation, the City’s noise policies. Specifically, construction would be prohibited between the hours of 8 p.m. and 7 a.m. Monday through Saturday and prohibited on Sunday or any Federal holiday, in accordance with RMC Chapter 8.36.030, Exemptions. No nighttime construction activities are anticipated. Project Site preparation for the Project would require cutting and removal of approximately 22,457 tons of recycled concrete and 5,461 tons of recycled asphalt. Materials cut would remain on site and would not be hauled away. Approximately 7,500 cubic yards of import would be required. Noise Background Sound is technically described in terms of amplitude (loudness) and frequency (pitch). The standard unit of sound amplitude measurement is the decibel (dB). The decibel scale is a logarithmic scale that describes the physical intensity of the pressure vibrations that make up any sound. The pitch of the sound is related to the frequency of the pressure vibration. Since the human ear is not equally sensitive to a given sound level at all frequencies, a special frequency-dependent rating scale has been devised to relate noise to human sensitivity. The A-weighted decibel scale (dBA) provides this compensation by discriminating against frequencies in a manner approximating the human ear's sensitivity. Noise, on the other hand, is typically defined as unwanted sound. A typical noise environment consists of a base of steady ambient noise that is the sum of various distant and indistinguishable noise sources. Superimposed on this background noise is the sound from individual local sources. These can vary from an occasional aircraft or train passing by to virtually continuous noise from traffic on a major highway. Several rating scales have been developed to analyze the adverse effects of community noise on people. Since environmental noise fluctuates over time, these scales consider that the effect of noise on people is largely dependent on the total acoustical energy content of the noise as well as the time of day when the noise occurs. For example, the equivalent continuous sound level (Leq) is the average acoustic energy content of noise for a stated period of time; thus, the Leq of a time-varying noise and that of a steady noise are the same if they deliver the same acoustic energy to the ear during exposure. The Day-Night Sound Kimley»Horn Page 5 kimley-horn.com 660 South Figueroa Street, Suite 2050, Los Angeles, CA 90017 213 261 4040 Level (Ldn) is a 24-hour average Leq with a 10 dBA “weighting” added to noise from 10:00 p.m. to 7:00 a.m. to account for noise sensitivity in the nighttime. The Community Noise Equivalent Level (CNEL) is a 24- hour average Leq with a 10 dBA weighting added to noise from 10:00 p.m. to 7:00 am. and an additional 5 dBA weighting from 7:00 p.m. to 10:00 p.m. to account for noise sensitivity in the evening and nighttime. Environmental Setting The Project Site is located within an urban environment and impacted by various noise sources. Mobile noise sources, especially traffic traveling along Walnut Grove Avenue, are the most common and substantial noise sources within the Project vicinity. The primary stationary noise sources near the Project Site are those associated with the surrounding commercial, institutional, recreational, and residential uses. Such stationary noise sources include mechanical equipment (e.g., heating, ventilation, and air conditioning [HVAC] equipment), idling and moving vehicles, parking lot activities, car radios and music playing, truck deliveries, dogs barking, people talking, recreational golf activities, and landscaping equipment. The noise associated with these sources may represent a single-event noise occurrence or short-term noise. Noise Measurements To quantify existing ambient noise levels in the Project vicinity, Kimley-Horn conducted four short-term (10-minutes) noise measurements between 12:40 p.m. and 1:40 p.m. on August 6, 2025; see Appendix A: Noise Data for additional details regarding how the ambient noise measurements were taken. The noise measurement sites were selected to be representative of the existing ambient noise levels at the noise- sensitive uses adjacent to the Project Site. Measurements of Leq are considered representative of the noise levels throughout the day. The average noise levels measured at each location are listed in Table 1: Existing Noise Measurements and shown on Figure 3: Noise Monitoring Locations Map.

The report covers both construction and operational noise impacts and describes a range of measures for controlling excessive noise and vibration. In general, the primary concern regarding vibration relates to potential damage from construction. The guidance document establishes criteria for evaluating the potential for damage for various structural categories from vibration. State State of California Noise Standards The State of California does not have standards for environmental noise, but the Governor’s Office of Land Use and Climate Innovation has established general plan guidelines for evaluating the compatibility of various land uses as a function of community noise exposure.2 The purpose of these guidelines is to maintain acceptable noise levels in a community setting for different land use types. The guidelines rank noise land use compatibility in terms of “normally acceptable,” “conditionally acceptable,” “normally unacceptable,” and “clearly unacceptable” noise levels for various land use types and are shown in Table 3: State and Land Use Compatibility Matrix.

Conditionally Acceptable: New construction or development should be undertaken only after a detailed analysis of the noise reduction requirements is made and needed noise insulation features included in the design. Conventional construction, but with closed windows and fresh air supply systems or air conditioning will normally suffice. Normally Unacceptable: New construction or development should generally be discouraged. If new construction or development does proceed, a detailed analysis of the noise reduction requirements must be made and needed noise insulation features included in the design.

Accessed September 28, 2025. In addition, California Government Code Section 65302(f) mandates that the legislative body of each county and city adopt a noise element as part of its comprehensive general plan. The local noise element must recognize the land use compatibility guidelines established by the Governor’s Office. California Code of Regulations, Title 24 The CCR, Title 24: Part 1, Building Standards Administrative Code, and Part 2, California Building Code, codify the State’s noise insulation standards. These noise standards apply to new construction in California for the purpose of interior noise compatibility from exterior noise sources. The regulations specify that acoustical studies must be prepared when noise-sensitive structures, such as residential buildings, schools, or hospitals, are located near major transportation noise sources, and where such noise sources create an exterior noise level of 65 dBA CNEL or higher. Acoustical studies that accompany building plans must demonstrate that the design of the structure would limit interior noise in habitable rooms to acceptable noise levels. For new residential buildings, schools, and hospitals, the acceptable interior noise limit for new construction is 45 dBA CNEL.

CEQA Significance Thresholds Based upon the criteria derived from the California Environmental Quality Act (CEQA) Guidelines Appendix G, a project would normally have a significant effect on the environment if it would: (a) Would the project generate a substantial temporary or permanent increase in ambient noise levels in the vicinity of the project in excess of standards established in the local general plan or noise ordinance, or applicable standards of other agencies? (b) Would the project generate excessive groundborne vibration or groundborne noise levels? (c) For a project located within the vicinity of a private airstrip or an airport land use plan or, where such a plan has not been adopted, within two miles of a public airport or public use airport, would the project expose people residing or working in the project area to excessive noise levels? Thresholds The Project is located within the City of Rosemead and as such, the noise and vibration impact analysis herein compares Project impacts at all identified sensitive receptors against the City’s standards. Construction Noise Pursuant to the City Noise Ordinance, construction between the hours of 10:00 p.m. and 7:00 a.m. Monday through Saturday, or at any time on weekends and nationally recognized holidays and that exceeds 65 dBA plus the limits specified in RMC Section 8.36.060(B) is prohibited. Therefore, this analysis uses the City’s threshold of 65 dBA for residential receptors to evaluate construction noise impacts at residential and institutional receptors. Operational Noise – Off-Site Traffic Noise Because a doubling of traffic is considered to cause a perceptible noise increase of 3-dBA above existing noise conditions, the significance for the off-site traffic noise is assessed based on a doubling of existing traffic conditions.3 3 California Department of Transportation, Technical Noise Supplement to the Traffic Noise Analysis Protocol, 2017. Kimley»Horn Page 15 kimley-horn.com 660 South Figueroa Street, Suite 2050, Los Angeles, CA 90017 213 261 4040 Operational Noise – On-Site Stationary Noise Operational noise impacts on the institutional and residential receptors are evaluated based on the standards within the City Noise Ordinance. A composite operational stationary noise impact would occur if the City’s daytime noise standard of 60 dBA and the substantial increase threshold of 5 dBA are exceeded or the City’s nighttime noise standard of 45 dBA is exceeded. Vibration The City has not established a quantitative vibration threshold. Therefore, this analysis uses the vibration thresholds provided by the FTA’s Transit Noise and Vibration Assessment Manual for building damage and Caltrans’ Transportation and Construction Vibration Manual for human annoyance. Based on the FTA criteria, construction vibration impacts would be significant if vibration levels exceed 0.3 inches-per- second (in/sec) peak particle velocity (PPV) for engineered concrete and masonry buildings. Based on the Caltrans’ criteria, construction vibration impacts with regards to human annoyance would be significant if vibration levels exceed the Caltrans’ threshold of 0.2 in/sec PPV at the nearest structure. Methodology Construction Noise Construction noise levels were based on typical noise levels generated by construction equipment published by the FTA and FHWA. The FTA’s Roadway Construction Noise Model (RCNM) was used to project construction noise levels at 50 feet from all pieces of equipment to determine the loudest construction phase. Utilizing the reference noise level data from RCNM, the highest calculated noise level would occur during the overlap of building construction, paving, and architectural coating. The SoundPLAN Model was used to determine how the sound from construction equipment would propagate and determine noise levels at the Project property line. SoundPLAN allows computer simulations of noise situations accounting for topography, noise sources, and intervening structures. Inputs to the SoundPLAN model included ground topography and ground type, existing and proposed intervening structures, noise source locations and heights, receiver locations, and sound power level data. The noise from each piece of construction equipment was modeled as an area source across the entire Project Site. This analysis is appropriate because Leq can be used to describe the noise level from the operation of each piece of equipment separately, and the levels can be combined to represent the noise level from all equipment operating at the Project Site concurrently during a given period. Operational Noise The analysis of the Project noise environment is based on noise prediction modeling and empirical observations. Reference noise level data are used to estimate the Project operational noise impacts from stationary sources. Noise levels were collected from published sources from similar types of activities and used to estimate noise levels expected with the Project’s stationary sources. The reference noise levels are used to represent a worst-case noise environment as noise levels from stationary sources can vary throughout the day. Vibration Ground-borne vibration levels associated with construction activities for the Project were evaluated utilizing typical ground-borne vibration levels associated with construction equipment, obtained from FTA published data for construction equipment. Potential ground-borne vibration impacts related to Kimley»Horn Page 16 kimley-horn.com 660 South Figueroa Street, Suite 2050, Los Angeles, CA 90017 213 261 4040 building/structure damage and interference with existing sensitive operations were evaluated, considering the distance from construction activities to nearby land uses and typically applied criteria for structural damage. Construction vibration levels were calculated using the following formula: PPVequip = PPVref x (25/D)1.5 where: PPVequip = the peak particle velocity in in/sec of the equipment adjusted for the distance PPVref = the reference vibration level in in/sec from Table 7-4 of the Federal Transit Administration, Transit Noise and Vibration Impact Assessment Manual, 2018. D = the distance from the equipment to the receiver Impact Analysis Threshold (a) Would the project generate a substantial temporary or permanent increase in ambient noise levels in the vicinity of the project in excess of standards established in the local general plan or noise ordinance, or applicable standards of other agencies? On-Site Construction Noise Construction noise typically occurs intermittently and varies depending on the nature or phase of construction (e.g., land clearing, grading, excavation, paving). Noise generated by construction equipment, including earth movers, material handlers, and portable generators, can reach high levels. During construction, exterior noise levels could affect the commercial and industrial receptors near the construction site. Project construction activities would include demolition, site preparation, grading, infrastructure improvements, building construction, paving, and architectural coating applications, as well as off-site improvements (i.e., sidewalk improvements and grind and overlay of Walnut Grove Avenue along the Project Site frontage). Typical operating cycles for these types of construction equipment may involve 1 or 2 minutes of full power operation followed by 3 to 4 minutes at lower power settings. Other primary sources of acoustical disturbance would be random incidents, which would last less than one minute (such as dropping large pieces of equipment or the hydraulic movement of machinery lifts). Typical noise levels associated with individual construction equipment are listed in Table 6: Typical Construction Noise Levels. It should be noted that the noise level values shown in Table 9 are for the equipment when operating at full power 50 feet from the sensitive receptor, without taking into account any intervening structures or topography that may reduce noise levels.

The FHWA’s RCNM was used to calculate construction noise at 50 feet for each of the Project construction phases. The highest calculated noise level at 50 feet would occur during the overlap of building construction, paving, and architectural coating. Construction noise was calculated accounting for each piece of equipment’s usage factor, or the fraction of time that the equipment would be in use at full power over a specific period of time, based on Table 1 of RCNM.4 Construction noise during the overlap of building construction, paving, and architectural coating at neighboring sensitive uses has been calculated using SoundPLAN. As this is the period of construction that would result in the greater noise level, all other construction phases would result in lower noise levels. Noise levels were based on the equipment used, distance to the nearest receptor, and acoustical usage factor for equipment. The noise from each piece of construction equipment was modeled as an area source across the entire Project Site. This methodology accounts for equipment operating throughout the Project Site and not at a fixed location for extended periods of time. See Appendix A for more information regarding the construction assumptions used in this analysis. The noise levels calculated in Table 7: Project Maximum Construction Noise Levels summarizes the exterior construction noise attributable to the Project. Implementation of Mitigation Measures MM NOI-1 and MM NOI-2, provided below, would reduce the Project’s construction noise levels. Specifically, MM NOI-1 requires the proper maintenance of construction equipment and the installation of noise 4 Federal Highway Administration, Roadway Construction Noise Model User Guide, Table1 Kimley»Horn Page 18 kimley-horn.com 660 South Figueroa Street, Suite 2050, Los Angeles, CA 90017 213 261 4040 shielding/muffling devices. The FHWA states that muffler systems can reduce noise levels by 10 dBA or more.5 MM NOI-2 requires the use of temporary noise barriers such as plywood walls with a minimum ½- inch thickness or sound blankets meeting a sound transmission class (STC) rating of 25 located along the western boundary of the Project Site. Sound blankets meeting a STC 25 rating can achieve a minimum seven to 10 dBA reduction for construction equipment with 200 Hz or lower frequency.6 A reduction of 10 dBA has been applied to the sound power levels for applicable pieces of construction equipment in SoundPLAN, accounting for the use of noise muffling devices required by MM NOI-1, and an eight-foot tall solid barrier, as required by MM NOI-2, along the western boundary of the Project Site has been input into the SoundPLAN model. As shown in Table 7, on-site construction noise with implementation of mitigation would not exceed the applicable thresholds. Therefore, construction noise impacts associated with on- site sources would be less than significant with mitigation incorporated.

Source: Refer to Appendix A for noise modeling results. As depicted in Table 7, Project construction noise would not exceed the City threshold of 65 dBA Leq at any of the identified receptors with mitigation incorporated. Additionally, The Project would comply with City’s allowable hours of construction, which are required in recognition that construction activities undertaken during daytime hours are a typical part of living in an urban environment and do not cause a significant impact. Construction-related noise would be temporary and would not result in a permanent increase in ambient noise levels in the area. Additionally, construction activities would be prohibited between the hours of between the hours of 10:00 p.m. and 7:00 a.m. Monday through Saturday, or at any time on weekends and nationally recognized holidays. The City’s permitted hours of construction are required in recognition that construction activities undertaken during daytime hours are a typical part of living in an urban environment and do not cause a significant impact. Therefore, impacts in regard to on-site construction noise would be less than significant. 5 Federal Highway Administration, Special Report - Measurement, Prediction, and Mitigation, Chapter 4 Mitigation, 2017. 6 Environmental Noise Control.

Kimley»Horn Page 19 kimley-horn.com 660 South Figueroa Street, Suite 2050, Los Angeles, CA 90017 213 261 4040 Off-Site Mobile Construction Noise In addition to on-site construction noise, the Project would generate mobile-source noise from delivery/haul trucks and construction workers traveling to and from the Project Site during Project construction via Walnut Grove Avenue. Project construction-generated trips would be temporary and cease with the end of construction. Traffic volumes along roadways within the Project vicinity would have to approximately double for the resulting traffic noise levels to generate a barely perceptible 3‐dBA increase.7 According to average daily traffic (ADT) data provided by Replica HQ, Walnut Grove Avenue between Rush Street and Drayer Lane has an ADT of 9,055.8 According to modeling assumptions in the air quality analysis prepared by Kimley-Horn in October 2025, the construction phase with the highest assumed number of vehicles would be building construction, when it is assumed, there would be up to 21 daily vendor truck trips and 139 daily worker (passenger vehicle) trips accessing the Project Site. As Project construction would not double the existing traffic volumes on Walnut Grove Avenue, the proposed Project would not generate enough traffic to result in a noticeable 3-dBA increase in ambient noise levels. Impacts associated with off-site construction mobile noise would be less than significant, and no mitigation is required. On-site Operational Noise The major on-site noise sources associated with the Project operations would include mechanical equipment (e.g., HVAC equipment), trash and recycling collection, parking and access noise, dog park, outdoor recreational space, pool equipment, and a water pump station. Mechanical Equipment. Potential stationary noise sources related to long-term Project operations would include residential mechanical equipment (e.g., HVAC equipment). A household air conditioning unit typically generates noise levels of approximately 52 dBA at 50 feet.9 It is conservatively assumed the nearest mechanical equipment (e.g., air conditioning unit) would be located on the side nearest the sensitive receptor. The noise levels associated with the mechanical equipment at the nearest sensitive receptors are shown in Table 8: Mechanical Equipment Noise Levels.

Pursuant to City Noise Ordinance the residential daytime threshold is 60 dBA, the residential nighttime threshold is 45 dBA, the commercial daytime noise threshold is 65 dBA, and the nighttime commercial threshold is 60 dBA. 3. The mechanical equipment would be shielded and the existing approximately 6-foot block wall along the western property line would remain. The noise level accounts for a 10 dBA reduction. 4. The Whittier Narrows Golf Course would not be operational during nighttime hours. Therefore, the nighttime threshold is not applicable. As shown in Table 8, the noise levels from mechanical equipment would exceed the City’s nighttime threshold of 45 dBA Leq at the residential uses located to the west of the Project Site (Sensitive Receptor 3). MM NOI-3 requires that mechanical equipment (e.g., air conditioning units) be located a minimum of 38 feet from residential receptors. With implementation of MM NOI-3, mechanical noise would be reduced to 44.4 dBA Leq at Sensitive Receptor 3. Therefore, mechanical noise would not exceed City daytime or nighttime exterior standards and impacts would be less than significant with mitigation incorporated. Trash and Recycling Pick Up. Trash and recycling would be collected along Walnut Grove Avenue. Trash and recycling trucks and pickup activities customarily generate noise levels of approximately 85 dBA at 3.3 feet.10 Trash and recycling truck pickup activity would occur infrequently and intermittently at the Project Site. Furthermore, trash and recycling pickup currently occurs under existing conditions and would not be a new noise source. The hours of trash and recycling pickup activity would depend on the service provider and would not be regulated by the Project. Therefore, Project implementation would not result in any significant effects relating to trash/recycling truck pickup noise levels. Parking. The townhouse buildings would include private attached garages. The Project Site would include guest parking along internal roadways for residential guests. Noises associated with parking activities include vehicles starting and stopping, vehicle doors closing, car horns and car alarms, loading and unloading, car radios, and conversations. The noise levels from these activities typically range from 53 to 61 dBA at 50 feet and are short-term.11 Parking activity would occur intermittently throughout the day and currently occurs under existing conditions. As such, parking activity noise associated with Project implementation would not be a new noise source and impacts would be less than significant. Dog Park. The Project would include a small and large dog park on the northeast corner of the Project Site. The dog park would be fenced and would include bench seating, picnic tables, and trash receptables. Noises associated with dog parks include dogs barking and howling, people talking, and music playing. The noise level from dogs barking and howling would be 73 dBA at approximately 3 feet.12 Table 9: Dog Park Noise Levels summarizes the dog park noise levels at the nearest sensitive receptors. 10 Kariel, H.

Pursuant to City Noise Ordinance the residential daytime threshold is 60 dBA, the residential nighttime threshold is 45 dBA, the commercial daytime noise threshold is 65 dBA, and the nighttime commercial threshold is 60 dBA. 3. The Whittier Narrows Golf Course would not be operational during nighttime hours. Therefore, the nighttime threshold is not applicable. Outdoor Space. The Project would include a community pool, group spa, cabanas, gas barbeque grills, community garden, picnic tables, open lawn play area, and tot-lot with play equipment. Per Assembly Bill 1307, Public Resources Code Section 21085, for residential uses, the effects of noise generated by Project occupants and their guests on human beings is not a significant effect on the environment. Therefore, no further analysis is required. Pool Equipment and Water Pump Station. The Project would include a community pool, group spa, and water pump station located on the southeast corner of the Project Site. The pool and spa equipment and water pump station would be entirely enclosed within a building and would not result in any measurable noise levels within the Project vicinity. Impacts would be less than significant, and no mitigation is required. Composite Noise Levels. An evaluation of the combined noise levels from the Project’s various on-site operational noise sources (i.e., composite noise level) was conducted to ascertain the potential maximum Project-related noise level. It is conservatively assumed that operational noise sources at the Project site would occur in a constant, simultaneous manner. However, noise sources would occur intermittently throughout the day. This analysis considers an exceedance of the noise standard at a sensitive receptor and a 5 dBA increase in noise levels over the existing ambient noise environment as the daytime significance criterion. Since ambient noise levels were not measured during the nighttime period, an exceedance of the noise standard is considered as the nighttime significance criterion. Table 10: Composite Noise Levels presents the composite noise level from the on-site Project-related noise sources with incorporation of MM NOI-3. As shown in Table 10, Project-generated composite noise levels would not cause a 5-dBA ambient increase at the nearest sensitive receptors. Impacts associated with Project operational composite noise would be less than significant.

Refer to Table 1 for the representative ambient noise levels. 2. A 5-dBA incremental increase is considered to be perceivable. 3. Potential impacts would occur if the noise generated by the Project would exceed the daytime noise standard and cause an incremental noise increase of 5 dBA above existing ambient conditions or exceed the nighttime noise standard. 4. Mechanical equipment noise levels at Sensitive Receptor 3 incorporates MM NOI-3, which requires a minimum distance of 38 feet between mechanical equipment and off-site sensitive receptors. Mobile Traffic Noise Project implementation would result in an increase in traffic trips along roadways near the project site. In general, a 3‐dBA increase in traffic noise is barely perceptible to people, while a 5‐dBA increase is readily noticeable. Traffic volumes on Project area roadways would have to approximately double for the resulting traffic noise levels to generate a barely perceptible 3‐dBA increase.13 According to Replica HQ, Walnut Grove Avenue between Rush Street and Drayer Lane has an existing ADT of 9,055.14 As such, the 1,375 total daily vehicle trips15 attributable to the Project would not double the existing traffic volumes on Walnut Grove. The proposed Project would not generate enough traffic to result in a noticeable 3-dBA increase in ambient noise levels and impacts associated with Project-generated mobile traffic would be less than significant. Threshold (b) Would the project generate excessive groundborne vibration or groundborne noise levels? On-site Construction Vibration 13 According to the California Department of Transportation, Technical Noise Supplement to Traffic Noise Analysis Protocol, 2013, it takes a doubling of traffic to create a noticeable (i.e., 3-dBA) noise increase. 14 ReplicaHQ, Replica Annual Average Daily Traffic (AADT) Data, 2024, https://www.replicahq.com/aadt.

Kimley»Horn Page 23 kimley-horn.com 660 South Figueroa Street, Suite 2050, Los Angeles, CA 90017 213 261 4040 Increases in groundborne vibration levels attributable to the Project would be primarily associated with short-term construction-related activities. Project construction would have the potential to result in varying degrees of temporary groundborne vibration, depending on the specific construction equipment used and the operations involved. Ground vibration generated by construction equipment spreads through the ground and diminishes in magnitude with increases in distance. The results from vibration can range from no perceptible effects at the lowest vibration levels, to low rumbling sounds and perceptible vibration at moderate levels, to slight damage at the highest levels. Groundborne vibrations from construction activities rarely reach levels that damage structures. The types of potential construction vibration impacts include human annoyance and building damage. Human annoyance occurs when construction vibration rises significantly above the threshold of human perception for extended periods of time at sensitive receptors. Land uses where people sleep or read are particularly sensitive to groundborne vibration. Building damage can be cosmetic or structural. Ordinary buildings that are not particularly fragile would not experience any cosmetic damage (e.g., plaster cracks) at distances beyond 30 feet. This distance can vary substantially depending on the soil composition and underground geological layer between vibration source and receiver. In addition, not all buildings respond similarly to vibration generated by construction equipment. The ground-borne vibration generated by construction equipment spreads through the ground and diminishes in magnitude with increases in distance. Equipment expected to be used at the Project Site that FTA guidance includes reference vibration levels for include vibratory roller, large bulldozer, loaded haul trucks, and small bulldozer. The City has not established quantitative vibration standards. Therefore, this analyses uses the FTA criteria of 0.3 in/sec PPV to evaluate building damage and the Caltrans’s criteria of 0.02 in/sec to evaluate human annoyance at the nearest structure to the Project Site. Table 11: Typical Construction Equipment Vibration Levels lists the vibration levels for typical construction equipment at 25 feet (reference distance) and 5 feet (the distance from the nearest structure to the Project Site property line). Table 11: Typical Construction Equipment Vibration Levels Equipment Reference Level PPV at 25 Feet (in/sec) PPV at 5feet (in/sec)1, 2 Vibratory Roller 0.21 2.348 Large Bulldozer 0.089 0.995 Loaded Trucks 0.076 0.850 Small Bulldozer 0.003 0.034 Exceeds Building Damage Threshold3 0.3 Yes Exceeds Human Annoyance Threshold4 0.2 Yes 1. Calculated using the following formula: PPVequip = PPVref x (25/D)1.5, where: PPVequip = the peak particle velocity in in/sec of the equipment adjusted for the distance; PPVref = the reference vibration level in in/sec from Table 7-4 of the Federal Transit Administration, Transit Noise and Vibration Impact Assessment Manual, 2018; D = the distance from the equipment to the receiver. 2. The distance from the nearest structure to the Project Site property line. The nearest structures to the Project Site are the residential uses located approximately 5 feet to the west. 3. Federal Transit Administration, Transit Noise and Vibration Impact Assessment Manual, 2018. 4. California Department of Transportation, Transportation and Construction Vibration Guidance Manual, 2020. Source: Federal Transit Administration, Transit Noise and Vibration Impact Assessment Manual, 2018. As stated above, construction activities are anticipated to occur up to the Project boundary line. The nearest structures to the Project Site property line are residential uses (Sensitive Receptor 3), located Kimley»Horn Page 24 kimley-horn.com 660 South Figueroa Street, Suite 2050, Los Angeles, CA 90017 213 261 4040 approximately 5 feet to the west. As indicated in Table 11, vibration velocities from typical heavy construction equipment operations that would be used during Project construction would exceed the FTA building damage threshold of 0.3 in/sec PPV and the Caltrans’ human annoyance threshold of 0.2 in/sec PPV at 5 feet. MM NOI-4 would be required to reduce vibration impacts to a less than significant level. MM NOI-4 would require buffer distances from the vibratory construction equipment to the adjacent receptors (residential uses to the west). Use of vibratory rollers would be prohibited within 26 feet, large bulldozers (dozers 50 tons and larger) would be prohibited within 15 feet, and loaded trucks would be prohibited within 14 feet of the residential uses to the west (Sensitive Receptor 3). As shown in Table 12: Mitigated Construction Equipment Vibration Levels, impacts with regard to structural damage and human annoyance at the nearest structure would be less than significant with implementation of MM NOI-4.

Off-Site Construction Vibration Project construction would additionally include off-site sidewalk and grind and overlay roadway improvements along the Walnut Grove Avenue frontage. The off-site improvements would require the use of vibratory rollers, loaded trucks, pavers, paving equipment, loaders, and tractors. The FTA guidance includes reference vibration levels for a vibratory roller and loaded trucks. The nearest structure to the off-site improvements would be located as near as 280 feet to the west (i.e., University of the West). As the structure would be located further from the off-site improvements than the required buffer distances listed in Table 16, it can be assumed that the vibration from off-site improvements would not exceed the FTA building damage threshold of 0.3 in/sec PPV or Caltrans’ human annoyance threshold of 0.2 in/sec PPV. As such, impacts associated with off-site improvement vibration would be less than significant, and no mitigation is required. With respect to construction trucks, Project construction would involve truck travel along nearby roadways, generating vibration events with each passing truck. During excavation, soil would be stockpiled by trucks within designated areas of the project site prior to export. According to the FTA’s Kimley»Horn Page 25 kimley-horn.com 660 South Figueroa Street, Suite 2050, Los Angeles, CA 90017 213 261 4040 Transit Noise and Vibration Impact Assessment, a truck rarely creates vibration levels that exceed 70 VdB (equivalent to 0.012 in/sec PPV) when on a roadway. The factors influencing levels of ground-borne vibration include vehicle speed, vehicle suspension, and wheel condition and type. The frequency of vibration events is not listed as an influencing factor for vibration velocity by the FTA. As such, multiple trucks traveling along the roadway would increase the frequency of vibration events but would not affect the vibration velocity experienced by receptors. Impacts would be less than significant, and no mitigation is required. Operational Vibration With respect to vibration-generating activities, operation of the Project would primarily involve personal automobiles used by residents accessing the parking spaces, occasional delivery trucks (such as UPS, FedEx, etc.), and trash and recycling collection trucks. Due to the rapid drop-off rate of ground-borne vibration and the short duration of the associated events, vehicular traffic-induced ground-borne vibration is rarely perceptible beyond the roadway right-of-way, and rarely results in vibration levels that cause damage to buildings in the vicinity.16 According to the FTA’s Transit Noise and Vibration Impact Assessment, trucks such as delivery trucks, refuse collection trucks, and occasional moving trucks rarely create vibration levels that exceed 70 VdB (equivalent to 0.012 in/sec PPV) when they are on roadways.17 Therefore, approval of the Project would not result in any significant effects relating to ground-borne vibration during Project operation.

The following measure shall be incorporated on all grading and building plans and specifications subject to approval of the City’s Building and Safety Division prior to issuance of a grading permit: • The developer shall ensure vibratory construction equipment will not operate within the construction buffer zone adjacent to the residential buildings along the western Project Site boundary. Specifically, loaded trucks shall not operate within 14 feet of the residential buildings to the west of the Project Site, large bulldozers (50 tons/100,000 pounds or larger) shall not operate within 15 feet of the residential buildings to the west of the Project Site, and vibratory rollers shall not operate within 26 feet of the residential buildings to the west of the Project Site. • The developer shall require the use of non-vibratory rollers (i.e., static or pneumatic rollers) or other less vibratory equipment within the buffer zone adjacent to the residential buildings along the western Project Site boundary. Threshold (c) For a project located within the vicinity of a private airstrip or an airport land use plan or, where such a plan has not been adopted, within two miles of a public airport or public use airport, would the project expose people residing or working in the project area to excessive noise levels? The Project Site is located approximately 3.3-miles to the southwest of the San Gabriel Valley Airport18 and is not located within the airport’s influence area or noise contours19. The Project Site is located approximately 0.14 miles to the southwest of the SCE Rosemead Heliport. The heliport is privately owned and operated by Southern California Edison (SCE) to occasionally monitor and inspect electrical infrastructure.20 As such, commercial activity would not occur at the heliport. The helicopter activity would be short in duration and permission would be required prior to any helicopter landing or launching from the helipad.21 The heliport noise is part of the existing noise environment and use of the heliport would not result in exposure of workers or residents at the Project Site to excessive noise levels. As the Project Site is not located within the vicinity of a private airstrip or airport land use plan, nor is it located within two miles of a private or public use airport, the Project would not expose people residing or working at the Project Site to excessive airport or airstrip-related noise levels, and no impact would occur. Conclusion Project implementation would result in less than significant construction and operational noise and vibration impact with mitigation incorporated. 18 The El Monte Airport was renamed the San Gabriel Valley Airport in November 2014. 19 Los Angeles County Airport Land Use Commission, Los Angeles County Airport Land Use Plan, El Monte Airport, 2004, https://planning.lacounty.gov/wp-content/uploads/2022/10/Los-Angeles-County-Airport-Land-Use-Plan.pdf.
