Item F-1 Agenda Report — Beverly Hills City Council, June 17, 2025 (part 2 of 3)

Implementation P16: Use, as appropriate, the “Guidelines for Noise Compatible Land Use” (Table 5, Guidelines for Noise Compatible Land Use), or other measures that are acceptable to the city, to guide land use and zoning reclassification, subdivision, conditional use and use variance determinations and environmental assessment considerations, especially relative to sensitive uses, as defined by this chapter, within a CNEL of 65 dB airport noise exposure areas and within a line-of-sight of freeways, major highways, railroads or truck haul routes.

of the Los Angeles Municipal Code. No person shall, between the hours of 9:00 p.m. and 7:00 a.m. of the following day, perform any construction or repair work of any kind upon, or any excavating for, any building or structure, where any of the foregoing entails the use of any power driven drill, riveting machine excavator or any other machine, tool, device or equipment which makes loud noises to the disturbance of persons occupying sleeping quarters in any dwelling hotel or apartment or other place of residence. In addition, the operation, repair or servicing of construction equipment and the job-site delivering of construction materials in such areas shall be prohibited during the hours herein specified. Any person who knowingly and willfully violates the foregoing provision shall be deemed guilty of a misdemeanor punishable as elsewhere provided in this Code.

Los Angeles Municipal Code Section 112.05, Maximum Noise Level of Powered Equipment or Powered Hand Tools, states that construction and industrial machinery shall not exceed a maximum of 75 dBA at a distance of 50 feet in a residential zone or within 500 feet of a residential zone, except where compliance is technically infeasible. Technical infeasibility shall mean that said noise limitations cannot be complied with despite the use of mufflers, shields, sound barriers and/or other noise reduction device ortechniques during the operation of the equipment.

CALIFORNIA ENVIRONMENTAL QUALITY ACT THRESHOLDS
The environmental analysis in this memorandum is patterned after the Initial Study Checklist recommended by the CEQA Guidelines. The issues presented in the Initial Study Checklist have been utilized as thresholds of significance in this section. Accordingly, a project may have a significant adverse impact related to noise and vibration if it would do any of the following:
• Generation of 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 (refer to Impact Statement NOI-1); • Generation of excessive groundborne vibration or groundborne noise levels (refer to Impact Statement NOI-2); and/or
• 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 (refer to Impact Statement NOI-3).

METHODOLOGY AND THRESHOLDS OF SIGNIFICANCE
Methodology
Noise levels from construction equipment and activities were modeled using the Federal Highway Administration’s Roadway Construction Noise Model (RCNM); refer to Appendix A for results of the RCNM modeling. Project construction equipment are based on the Oakhurst Apartment Project Air Quality Assessment prepared by Michael Baker International, dated September 2024.

Thresholds of Significance
City of Beverly Hills
Construction Noise
Based on the discussion with the City of Beverly Hills6 , construction noise would be significant if 1)
construction activities occurring on the project site generate a noise increase of five dBA or more outside the hours permitted by the City of Beverly Hill’s noise ordinance at the project site (i.e., between 6:00 p.m. and 8:00 a.m. on weekdays, or at any time on Saturday, Sunday, or a public holiday), or 2) construction activities occurring on a project site generate a noise increase of five dBA or more during daytime hours at uses identified in Section 5-1-206 of the City of Beverly Hills’ Noise Ordinance, which include schools, hospitals, churches, or institutes of learning.

Operational Noise
According to the City of Beverly Hills’ Noise Ordinance, it is unlawful for any stationary source such as mechanical equipment (air condition and heating units) to increase the ambient noise levels at the property line by 5 dBA. However, the City of Beverly Hills does not have a threshold of significance for other operational noise sources (traffic noise, parking lot noise, crowd noise, etc.). As a conservative analysis, these operational noise sources would utilize the threshold of significance used for stationary sources. As such, a significance increase in noise level would occur if operational noise sources would increase the ambient noise levels by 5 dBA.

City of Los Angeles
Construction Noise
According to Los Angeles Municipal Code Section 112.03, Construction Noise, construction-related noise levels are governed by Section 41.40, Noise due to Construction, Excavation Work – When Prohibited.

According to Los Angeles Municipal Code Section 41.40, construction would be required to occur between the hours of 9:00 p.m. and 7:00 a.m. of the following day. Additionally, pursuant of Los Angeles Municipal Code Section 112.05, Maximum Noise Level of Powered Equipment or Powered Hand Tools, construction and industrial equipment should not exceed a maximum of 75 dBA at a distance of 50 feet in a residential zone or within 500 feet of a residential zone, except where compliance is technically infeasible.

Operational Noise
Los Angeles Municipal Code, Section 111.02, Sound Level Measurement Procedure and Criteria, provides procedures and criteria for the measurement of the sound level of “offending” noise sources. According to the Los Angeles Municipal Code, a noise level increase of 5 dBA over the existing average ambient noise level at an adjacent property line is considered a noise violation. As such, a significance increase in noise level would occur if operational noise sources would increase the ambient noise levels by 5 dBA. 6 9229 Wilshire Boulevard – Class 32 Report Discussion, on January 5, 2024.

IMPACT ANALYSIS
NOI-1 Generation of 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?
Less Than Significant Impact. As the project site is located within the jurisdiction of both the City of Beverly Hills and the City of Los Angeles, the analysis below would compare the project’s noise impact to the City of Beverly Hills and City of Los Angeles noise thresholds. Both the City of Beverly Hills and City of Los Angeles Noise Elements establishes guidelines for controlling construction and operational noise within their jurisdiction.

Construction Noise Impacts
Ground-borne noise and other types of construction-related noise impacts typically occur during the initial demolition and grading phases, which has the potential to create the highest levels of noise. Construction equipment produce maximum noise levels when equipment is operating under full power conditions (i.e., the equipment engine at maximum speed). However, equipment used on construction sites typically operates under less than full power conditions, or part power. To more accurately characterize construction-period noise levels, the average (Leq) noise level associated with each construction stage is calculated based on the quantity, type, and usage factors for each type of equipment that would be used during each construction stage. These noise levels are typically associated with multiple pieces of equipment simultaneously operating on part power.

Los Angeles Municipal Code Section 112.05 prohibits the use of construction and industrial equipment if the maximum noise levels exceed 75 dBA at 50 feet within a residential zone. Additionally, it should be noted that a portion of the project site is within the jurisdiction of the City of Beverly Hills. As stated above, construction noise in the City of Beverly Hills would be significant if 1) construction activities occurring on the project site generate a noise increase of five dBA or more outside the hours permitted by the City of Beverly Hill’s noise ordinance at the project site (i.e., between 6:00 p.m. and 8:00 a.m. on weekdays, or at any time on Saturday, Sunday, or a public holiday), or 2) construction activities occurring on a project site generate a noise increase of five dBA or more during daytime hours at uses identified in Section 5-1- 206 of the City of Beverly Hills’ Noise Ordinance, which include schools, hospitals, churches, or institutes of learning. For the purposes of this analysis, a construction noise impact would occur at the multi-family residential uses if construction noise generated from mobile construction equipment exceeds 75 dBA at 50 feet pursuant of the Los Angeles Municipal Code. Additionally, a significant impact would occur if construction occurring outside the permitted hours result in a 5 dBA increase or if construction would result in a 5 dBA increase at schools, hospitals, churches, or institutes of learning pursuant of the City of Beverly Hills noise ordinance.

The estimated construction noise levels at the nearest noise-sensitive receptors are presented in Table 6, Construction Noise Levels at the Nearest Residential Receptors. Noise levels from construction equipment and activities were modeled using the Federal Highway Administration’s RCNM. To present a conservative impact analysis, the estimated noise levels were calculated for a scenario in which all heavy construction equipment were assumed to operate simultaneously.

The nearest sensitive uses (multi-family residential uses) are located approximately 15 feet from the project site to the north and south. However, construction activities would occur throughout the project Oakhurst Apartments Project
Noise and Vibration Assessment 19
site, and it should also be noted that construction noise levels would intermittently occur for a few days when construction equipment is operating closest to the nearest sensitive uses. The remainder of the time, the construction noise levels would be much lower because the equipment would be working in an area farther away from the existing sensitive uses. The General Noise Assessment methodology prescribed in the FTA Transit Noise and Vibration Impact Assessment Manual, recommends evaluating construction noise from the center of the site, stating under the variable distance in its construction noise calculation to “assume that all equipment operates at the center of the project.” As such, the construction noise levels shown in Table 6 are estimated using the distance from the center of the project site to the property line of the existing sensitive receptors, which is approximately 45 feet from the closest sensitive receptor to the north and south.

Construction Noise Levels at the Nearest Residential Receptors Phase Estimated Exterior Construction Noise Level at 45 feet (Center of the Site to Residential Uses to the North and South) (dBA Leq)1
Demolition 87.8
Grading 85.5
Building Construction 88.5
Architectural Coating 74.6
Notes:

1. These noise levels conservatively assume the simultaneous operation of all heavy construction equipment at the same precise location.

Modeled heavy construction equipment include tractors, dozer, concrete saw, and excavator during the demolition phase, grader, dozer, and tractors during the grading phase, crane, forklift, generator, tractor, air compressor, generator, welders, concrete saw, and cement mixer during the building construction phase, and air compressor during the architectural coating phase.

Source: Federal Highway Administration, Roadway Construction Noise Model (RCNM), 2006 (see Appendix A).

As shown in Table 6, construction-generated noise levels would range from 74.6 dBA Leq to 88.5 dBA Leq at the nearest sensitive receptor (multi-family residences) property boundary located approximately 45 feet to the north and south from the geographic center of the project site. Additionally, it should be noted that modeling of construction noise levels in Table 6 assumes that construction equipment would operate simultaneously and represents a worse-case scenario. According to the Los Angeles Municipal Code Section 112.05, construction and industrial equipment should not exceed a maximum noise level of 75 dBA at 50 feet in a residential zone or within 500 feet of a residential zone, except where compliance is technically infeasible. As shown in Table 6, noise levels during each phase (except for architectural coating) would have an average construction noise level that exceeds the 75 dBA threshold. As part of the proposed project, a Construction Noise Management Plan (CNMP) would be implemented to reduce overall construction noise levels; refer to Appendix B, Construction Noise Management Plan. According to the CNMP, the project would use construction equipment with properly operating and maintained mufflers, locate stationary construction equipment so that emitted noise is directed away from the nearest noise sensitive receptors, and limit construction hours to be consistent with the Los Angeles Municipal Code and Beverly Hills Noise Ordinance. The required features in the CNMP would reduce noise levels by approximately 5 dBA, resulting in construction-generated noise levels ranging from 69.4 to 83.5 dBA Leq. It should be noted that the implementation of a noise barrier would further reduce construction noise levels; however, this feature was considered and determined to be infeasible as the project is surrounded by multi-story buildings, which would require noise barriers as tall as three stories to block the line-of-sight. As such, with the required features outlined in the CNMP, the project would implement all technically feasible measures to reduce construction noise levels, and therefore would comply with the Los Angeles Municipal Code requirements.

Noise and Vibration Assessment 20
According to the Los Angeles Municipal Code Section 41.40, construction would be prohibited between the hours of 9:00 p.m. and 7:00 a.m. of the following day. Pursuant of the Beverly Hills Noise Ordinance, construction would be prohibited between the hours of 6:00 p.m. and 8:00 a.m. on any day and construction shall not occur on Sunday or a public holiday. As such, to comply with both the Los Angeles Municipal Code and the Beverly Hills Noise Ordinance, noise generated from project construction activities would only occur during the hours of 8:00 a.m. and 6:00 p.m. on weekdays and would not occur on a Sunday or public holiday. Additionally, because the project site is located within a residential zone, project construction would not occur on Saturday pursuant of the Beverly Hills Noise Ordinance. It should be noted that construction activities would be exempt from the Beverly Hills noise standards per Noise Ordinance Section 5-1-205 within the permitted construction hours 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 disruption.

Furthermore, the project site is not located near any school, hospital, or institute of learning and daytime construction activities at the project site would not result in a significant impact at these receptors. The nearest school (Hawthorne Elementary School) is located approximately 0.75 mile to the west of the project site and the nearest hospital use (Cedars Sinai Medical Center) is approximately 0.5 miles to the east. Therefore, on-site construction noise would attenuate over long distances such that construction activities would not be audible at these receptors.

It should be noted that the nearest religious use (Young Israel of North, within the City of Beverly Hills) is located approximately 1,150 feet to the west (0.20 miles). The estimated construction noise levels at the nearest religious use receptors are presented in Table 7, Construction Noise Levels at the Nearest Religious Receptor.

Notes:

2. These noise levels conservatively assume the simultaneous operation of all heavy construction equipment at the same precise location.

Source: Federal Highway Administration, Roadway Construction Noise Model (RCNM), 2006 (see Appendix A).

As indicated in Table 7, construction of the proposed project would result in noise levels ranging from

46.5 to 60.3 dBA Leq at the nearest religious use. A short-term noise measurement was conducted near the closest religious use and indicates that the existing ambient noise level is approximately 63.1 dBA; refer to Table 3. As such, construction of the proposed project would not result in a 5 dBA increase over the existing ambient noise levels as identified in Section 5-1-206 of the Beverly Hills Noise Ordinance.

Thus, less than significant noise impacts from construction activities would result.

Oakhurst Apartments Project
Noise and Vibration Assessment 21
Construction Trips Noise Impacts
Construction activities would also cause increased noise along access routes along the Beverly Boulevard, Alden Drive, and Oakhurst Drive due to movement of equipment and workers, as well as haul trips.

According to the California Department of Transportation (Caltrans), a doubling of traffic (100 percent increase) on a roadway would result in a perceptible increase in traffic noise levels (3 dBA).7 As such, a significant impact would occur if construction-related trips double existing traffic volumes.

According to the Air Quality Assessment, it is anticipated that project construction would generate a maximum of 18 hauling trips per day, 100 worker trips per day, and 22 vendor trips per day. The existing ADT along Beverly Boulevard is 14,100 for eastbound traffic and 16,500 for westbound traffic. 8 Per 24-
hour traffic counts conducted in 1999 as part of the City of Beverly Hills General Plan EIR, Oakhurst Drive experiences approximately 2,397 average daily trips (ADT).9 While this data is outdated, the 24-hour traffic volume counts from 1999 is used as a conservative analysis as current traffic volumes are significantly higher than 1999. Specifically, the City of Beverly Hills Technical Noise Supplement to the Traffic Noise Analysis Protocol utilizes a growth factor of 0.8433 percent per year when factoring traffic volumes up to 2005 where applicable. As such, it would be appropriate to assume that traffic volumes factored to the year 2024 would be greater than 2,397 ADT. Nevertheless, as a conservative analysis, the lower 2,397 ADT along Oakhurst Drive from 1999 is utilized. Based on the Cedars-Sinai Medical Center West Tower Project, Appendix E, Traffic Impact Study, Alden Drive between Swall Drive and Clark Drive experiences approximately 3,468 ADT.
10 While this roadway segment is not directly located within the proximity of the proposed project, it would be appropriate to assume that ADT along this roadway would be similar. The combined total of project-related construction trips (140 trips) would not result in a doubling of existing traffic volumes along Oakhurst Drive or Alden Drive. Similarly, construction trips from the proposed project would not double existing traffic volumes for eastbound and westbound traffic along Beverly Boulevard. As the construction-related trips would not double existing traffic volumes, there would not be a perceptible increase (3 dBA) in traffic noise. Additionally, mobile traffic noise from construction trips would be temporary and would cease upon project completion. Thus, impacts in this regard would be less than significant.

Long-Term Operational Noise Impacts
Off-Site Mobile Noise
Future development generated by the proposed project would result in some additional traffic on adjacent roadways, thereby potentially increasing vehicular noise in the vicinity of existing and proposed land uses. The most prominent source of mobile traffic noise in the project vicinity is along Beverly Boulevard, Alden Drive, and Oakhurst Drive. The proposed development would also include a private alleyway located directly east of the project site.

Oakhurst Apartments Project
Noise and Vibration Assessment 22
According to the Air Quality Assessment, the project would generate approximately 283 ADT on weekdays, 255 ADT on Saturday, and 213 ADT on Sunday based on the proposed land use types. As a conservative analysis, the largest number of trips (283 ADT) would be compared to existing traffic volumes. It should be noted that traffic from existing uses on site was not considered, which results in a more conservative analysis. According to the California Department of Transportation (Caltrans), a doubling of traffic (100 percent increase) on a roadway would result in a perceptible increase in traffic noise levels (3 dBA).

As discussed above, the existing ADT along Beverly Boulevard is 14,100 for eastbound traffic and 16,500 for westbound traffic.
11 24-hour traffic counts conducted in 1999 states that Oakhurst Drive experienced around 2,397 ADT. Alden Drive experiences traffic volumes of approximately 3,468. 12 As such, the
project’s 283 ADT would not double existing traffic volumes along Beverly Boulevard (14,100 ADT for eastbound traffic and 16,500 ADT for westbound traffic), Oakhurst Drive (2,397 ADT), and Alden Drive (3,468 ADT). Thus, the project would not result in a perceptible increase traffic noise level (3 dBA) as the project’s operational trip would not double existing traffic volumes. As such, a less than significant impacts would occur in this regard.

It should be noted that the project would use the alleyway for vehicular ingress and egress to the underground parking lot. The alleyway is already used under the existing conditions by surrounding residential development for vehicular movement into parking stalls or underground parking lots.

Additionally, as previously discussed above, the estimated daily trips from the proposed project would represent a nominal increase in daily traffic compared to existing traffic conditions along Beverly Boulevard and Alden Drive which connect to the private alleyway. Thus, a less than significant impact would occur.

Stationary Noise
Stationary noise sources associated with the project would include the operation of mechanical equipment and outdoor gathering areas.

Mechanical Equipment Noise
Heating, ventilation, and air conditioning (HVAC) units would be installed on the roof of the proposed building. Typically, mechanical equipment noise is approximately 66 dBA at 3 feet from the source.13 Based upon the Inverse Square Law, sound levels decrease by 6 dBA for each doubling of distance from the source.14 The mechanical equipment (HVAC units) would be located within a screened mechanical zone located along the northwestern portion of the roof of the proposed structure. The nearest sensitive receptor to the project site is the multi-family residence located approximately 24 feet to the north of the proposed mechanical units (15 feet from the project boundary plus 9 feet setback). At this distance, the noise levels from a single HVAC unit would be approximately 48 dBA at the nearest sensitive receptor. 11 City of Beverly Hills Traffic Engineering, Traffic Flow Data, https://www.beverlyhills.org/950/Traffic-Engineering, accessed July 11, 2024. 12 City of Los Angeles, Cedars-Sinai Medical Center West Tower Project, Appendix E, Traffic Impact Study https://planning.lacity.gov/eir/CedarSinia/FEIR/Appendices/Appendix%20E%20%E2%80%93Traffic%20Impact%20Study.pdf, accessed September 26, 2024. 13 Elliott H.

Oakhurst Apartments Project
Noise and Vibration Assessment 23
This analysis assumes approximately 15 five-ton HVAC units (one single five-ton HVAC unit for every 2,500 square feet), which would generate a combined noise level of approximately 60 dBA when operating simultaneously.15 However, the proposed HVAC units would be shielded by a parapet wall, which would completely shield the HVAC units and break the line-of-sight between the HVAC units and the sensitive receptors to the north. As such, the parapet wall would further attenuate operational noise from the HVAC units by approximately 8 dBA.
16 As such, noise levels from the proposed HVAC units would be approximately 52 dBA and would not increase noise levels by more than 5 dBA over ambient daytime and nighttime noise levels (refer to Table 2, 67.0 LDay and 49.6 dBA LNight). Furthermore, HVAC units currently exist on-site and would not represent a new noise source.

Therefore, the proposed HVAC units would not generate noise levels in excess of 5 dBA over existing ambient daytime and nighttime noise level in the project vicinity in compliance with Section 5-1-202 of the Beverly Hills Noise Ordinance and Section 111.02 of the Los Angeles Municipal Code. Thus, the proposed project would not result in significant noise impacts from HVAC units to the nearest sensitive receptor, and stationary noise levels from the proposed HVAC units would comply with the Beverly Hills Noise Ordinance and Los Angeles Municipal Code. Impacts in this regard would be less than significant.

Outdoor Gathering Area Noise
The project would include an open-air courtyard located centrally on the project site. The open-air courtyard is located centrally on the second floor and would be surrounded on all sides by the proposed building. The courtyard has the potential to be accessed by groups of people intermittently for various occasions (e.g., events, other social gatherings, etc.). Noise generated by groups of people (i.e., crowds) is dependent on several factors including vocal effort, impulsiveness, and the random orientation of the crowd members. Crowd noise is estimated at 60 dBA at one meter (3.28 feet) away for raised normal speaking.17 This noise level would have a +5 dBA adjustment for the impulsiveness of the noise source, and a -3 dBA adjustment for the random orientation of the crowd members.18 Therefore, crowd noise would be approximately 62 dBA at one meter from the source (i.e., open-air courtyard).

At approximately 45 feet (center of the project site to the nearest receptor), crowd noise levels would be approximately 37 dBA. As such, crowd noise from the proposed project would not increase noise levels more than 5 dBA over ambient daytime and nighttime noise levels (refer to Table 2, 67.0 LDay and 49.6 dBA LNight). As such, noise from crowds gathering at the open-air courtyard would not be audible to the nearby sensitive receptors.

According to the Supreme Court of California ruling in the Make UC a Good Neighbor v. the Regents of the University of California, it was determined that “social noise” (noise created by humans) was not an environmental impact required by CEQA to be analyzed for residential projects. As such, Assembly Bill 1307 was signed into law in September 2023. Assembly Bill 1307 added Public Resources Code Section 21085 which states “For the purposes of this division, for residential projects, the effects of noise generated by the project occupants and their guest on human beings is not a significant effect on the environment”. As such, the analysis shown above was only included for informational purposes. Impacts would be less than significant.

Noise and Vibration Assessment 24
Cumulative Operational
Off-Site Mobile Noise
As discussed above, the project’s potential traffic redistribution noise levels would not exceed the established significance criteria (i.e., 3.0 dB increase and exceedance of 65 dBA CNEL). As discussed above, the proposed project would not double existing traffic volumes along surrounding roadways and was determined to have a less than significant impact. The closest related project is the 401 North Oakhurst Drive which would remodel the existing six-unit residential building for the construction a taller multifamily residential development with more dwelling units. The 401 North Oakhurst Drive currently on file would construct a total of 25 dwelling units. As the proposed project would construct a total of 52 units, it can be assumed that the 401 North Oakhurst Drive would result in a traffic generation ranging from 107 to 142 ADT (approximately half of the proposed project). Even with the addition of 401 North Oakhurst Drive’s projected ADT to the proposed project’s traffic generation, the combined total would not double existing traffic volumes along Oakhurst Drive, Alden Drive, and Beverly Boulevard. Therefore, the proposed project, in combination with cumulative traffic noise levels, would result in less than significant impacts.

Stationary Noise
Although the proposed multi-family residential building may occur in proximity to other future developments, the proposed development would not involve stationary noise sourcesthat are capable to produce substantial noise above existing ambient noise levels and was determined to result in a less than significant impact. Stationary noise sources associated with the project would include the operation of mechanical equipment (heating, ventilation, and air conditioning) and outdoor gathering areas, all of which are typical noise sources that are currently present in any urban setting. Additionally, as noise dissipates as it travels away from its source, noise impacts from stationary sources would be limited to each of the respective sites and their vicinities. As discussed above, the closest related project is the 401 North Oakhurst Drive. It should be noted that the 401 North Oakhurst Drive currently on file proposes a 11-story tall structure. As such, HVAC units of the related project would be located further above the existing surrounding buildings, which would help minimize noise. Nevertheless, the 401 North Oakhurst Drive would be subjected to BHMC Section 5-1-202, requiring HVAC units’ noise not to exceed 5 dBA over existing ambient noise level. Thus, compliance with BHMC Section 5-1-202 would ensure that the project and any cumulative development in the project vicinity would not be anticipated to result in a significant cumulative impact. A less than significant impact would occur in this regard.

Mitigation Measures: No mitigation is required.

NOI-2 Exposure of persons to or generation of excessive groundborne vibration or groundborne noise levels?
Short-Term Construction Vibration Impacts
Project construction can generate varying degrees of groundborne vibration, depending on the construction procedure and the construction equipment used. Operation of construction equipment generates vibrations that spread through the ground and diminish in amplitude with distance from the source. The effect on buildings located in the vicinity of the construction site often varies depending on Oakhurst Apartments Project
Noise and Vibration Assessment 25
soil type, ground strata, and construction characteristics of the receiver building(s). 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 Caltrans Transportation and Construction Vibration Manual identifies various vibration damage criteria for different building classes. This evaluation uses the Caltrans architectural damage criterion for continuous vibrations at historic and some old buildings of 0.25 inch-per-second (inch/second) PPV. The nearest structure to the project site is 416 North Oakhurst Drive to the north. This structure was built in 1965 and may be eligible to be listed in the California Register due to the structure being more than 50 years old. While a historical resources survey has not been prepared for 416 North Oakhurst Drive, as a conservative analysis, the threshold of 0.25 inch/second PPV would be used. The types of construction vibration impacts include human annoyance and building damage. Human annoyance is assessed based on levels of perception, with a PPV of 0.08 inch/second being considered “readily perceptible,” 0.1 inch/second being perceptible and may begin to annoy receptors, 0.2 inch/second being perceptible and may annoy people within buildings, and 0.4 to 0.6 inch/second as “unpleasant”; refer to Table 1. Human annoyance occurs when construction vibration rises significantly above the threshold of human perception for extended periods of time. Construction of the proposed project would occur over approximately 32 months and would include demolition, grading, building construction, and architectural coatings. Typical vibration produced by construction equipment is illustrated in Table 8, Typical Vibration Levels for Construction Equipment.

Table 8
Typical Vibration Levels for Construction Equipment
Equipment Approximate peak particle velocity at 25 feet (inch/sec)
Approximate peak particle velocity at 15 feet
(inch/sec)1
Large bulldozer 0.089 0.1915
Loaded trucks 0.076 0.1635
Small bulldozer 0.003 0.0065
Notes:

1. Calculated using the following formula:

PPV equip = PPV ref x (25/D)1.1
where: PPV equip = the peak particle velocity in in/sec of the equipment adjusted for the distance PPV ref = the reference vibration level in in/sec from Table 7-4 of the FTA Transit Noise and Vibration Impact Assessment Guidelines
D = the distance from the equipment to the receiver
Source: California Department of Transportation, Transportation and Construction Vibration Guidance Manual, April 2020.

As indicated in Table 8, vibration velocities from typical heavy construction equipment operation would range from 0.003 to 0.089 inch/second PPV at 25 feet from the source of activity. The nearest structure to the project site occupied by sensitive receptors is the existing multi-family residential building (416 North Oakhurst Drive) located approximately 15 feet to the north when measured from the project site property line to the sensitive receptor’s building façade (approximately 15 feet setback). Vibration level during the operation of construction equipment would be approximately 0.0065 inch/second PPV to

0.1915 inch/second PPV at 15 feet; refer to Table 8. As a result, construction groundborne vibration would not be capable of exceeding the 0.25 inch/second PPV significance threshold for vibration to the historic buildings and other old buildings and a less than significant impact would occur in this regard.

It should be noted that the closest structure to the project site (416 North Oakhurst Drive) would not experience vibration velocities that exceed the 0.25 inch/second PPV significance threshold for vibration Oakhurst Apartments Project

at historic buildings and other old buildings. Other potential historic buildings in the project vicinity are located further from the project site than 416 North Oakhurst Drive and therefore would be subject to lower vibration levels from construction of the project. As the threshold of 0.25 inch/second PPV for historic buildings would not be exceeded at the nearest structure, a less than significant impact would occur at other potential historic buildings nearby.

As indicated in Table 8, vibration velocities from heavy construction equipment operation would be below the 0.2 inch/second factor for human annoyance within buildings. As discussed above, 0.2 inch/second factor is the threshold in which receptors within buildings may begin to experience annoyance due to vibration velocities. However, it should be noted that vibration velocities would only occur when construction equipment are operational closer to the sensitive receptor and would diminish as they move away. Additionally, construction equipment would only be operational for short periods of time, further limiting the overall vibration velocities felt by nearby sensitive receptors. As such, equipment would not be operational at peak vibration velocities for extended periods of time and impacts would be less than significant in this regard.

Long-Term Operational Vibration Impacts
The project would involve construction of a multi-family residential building and would not generate groundborne vibration during its operation that could be felt by surrounding uses. The project operation would not involve railroads or substantial heavy truck operations, and therefore would not result in vibration impacts at surrounding uses. Thus, no impact would occur in this regard.

Mitigation Measures: No mitigation is required.

NOI-3 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??
No Impact. The nearest public use airport to the project site is the Santa Monica Municipal Airport which lies approximately 5.2 miles to the southwest of the project site. According to Exhibit 3-4, Year 2018 CNEL Contours Santa Monica Airport, of the City’s Calendar Year 2018 CNEL Contours Santa Monica Municipal Airport, the project site is not located within the Santa Monica Municipal Airport CNEL contours. 19 The
project site is not in the vicinity of a private airstrip. Therefore, no impact related to airport land use compatibility would occur.

Mitigation Measures: No mitigation is required.

Attn: Minjee Hahm
Dear Ms. Hahm,
This Construction Noise Management Plan (CNMP) for the proposed Oakhurst Apartments Project (project), located in the City of Los Angeles and City of Beverly Hills, California describes the best management practices that the contractor will implement to minimize noise disruptions on surrounding properties during construction and to ensure compliance with the City of Los Angeles and City of Beverly Hills noise ordinance.

The project site is surrounded with sensitive receptors to the north, east, and south. The receptors (multifamily residences) to the north are located approximately 15 feet from the project site boundary, the receptors (multi-family residences) to the east are located approximately 35 feet from the project site boundary, and the receptors (multi-family residences) to the south are located approximately 20 feet from the project site boundary. These receptors could be exposed to temporary and intermittent construction noise levels. The project would implement the techniques described below to manage noise generated from project construction.

Construction Noise Control Techniques
To manage construction noise, the project includes the following:
• Construction contracts will specify that all construction equipment, fixed or mobile, will be equipped with properly operating and maintained mufflers and other state-required noise attenuation devices. • A sign, legible at a distance of 50 feet, will be posted at the project construction site providing a contact name and a telephone number where residents can inquire about the construction process and register complaints. This sign will indicate the dates and duration of construction activities. In conjunction with this required posting, a noise disturbance coordinator will be identified to address construction noise concerns received. The coordinator will be responsible for responding to any local complaints about construction noise. When a complaint is received, the disturbance coordinator will notify both the City of Los Angeles and City of Beverly Hills within 24 hours of the complaint and determine the cause of the noise complaint (starting too early, malfunctioning muffler, etc.) and will implement reasonable measures to resolve the complaint. All signs posted at the construction site will include the contact name and the telephone number for the noise disturbance coordinator.
• During construction, stationary construction equipment will be placed such that emitted noise is directed away from sensitive noise receivers.
• Per Section 41.40 of the City of Los Angeles Municipal Code, construction activities will be limited to the hours between 7:00 a.m. and 9:00 p.m. on all days. Per the City of Beverly Hills Noise Ordinance, construction will be limited to the hours between 8:00 a.m. and 6:00 p.m. on any days and all construction activities will be prohibited on Sundays and holidays. To comply with the City of Los Angeles and City of Beverly Hills requirements, construction of the project will only occur during the hours of 8:00 a.m. and 6:00 p.m. on all days. Construction will not occur during Sundays and holidays.

Subject: Oakhurst Apartments Project – Air Quality Assessment

PURPOSE
The purpose of this technical memorandum is to evaluate potential short- and long-term air quality impacts that would result from the construction and operation of the proposed Oakhurst Apartments Project (project), located in the Cities of Los Angeles and Beverly Hills, California.

PROJECT LOCATION
The community of Beverly Grove is a neighborhood within the City of Los Angeles, regionally located in the western portion of Los Angeles County (County), approximately six miles west of Downtown Los Angeles; refer to Exhibit 1, Regional Vicinity Map. Surrounding communities include Hollywood to the north, Silverlake-Echo Park and Westlake to the east, South Central Los Angeles and West Adams-LeimertBaldwin Hills to the south, and West Los Angeles to the west. The City of Beverly Hills is roughly 5.7 square miles and located in the southwestern portion of the County, approximately 8.5 miles northwest of Downtown Los Angeles. Surrounding jurisdictions include the City of Los Angeles along all sides and the City of West Hollywood to the east.

The project site is specifically located at 412 North Oakhurst Drive within the Cities of Los Angeles and Beverly Hills. As shown on Exhibit 2, Site Vicinity, the site encompasses approximately 0.35-acre (0.10- acre within Beverly Hills and 0.25-acre within Los Angeles) bordered to the west by North Oakhurst Drive.

Surrounding land uses generally include residential uses on all sides. Regional access to the site is provided via State Route 2 (SR-2; Santa Monica Boulevard), Interstate 10 (I-10), State Route 187 (SR-187; Venice Boulevard), and Interstate 405 (I-405). Local access to the site is provided via Beverly Boulevard, Burton Way, South Doheny Drive, and North Oakhurst Drive.

EXISTING SITE CONDITIONS
The project site is currently developed with an existing occupied multi-family residential building located at 412 North Oakhurst Drive within the portion of the lot located within the City of Beverly Hills (within Beverly Hills; Assessor’s Parcel Number [APN] 4335-006-043) and within the portion of the lot located within the City of Los Angeles (within Los Angeles; APN 4335-006-044). The existing residential building is approximately 32,400-gross square feet and includes 15 residential units that are a maximum of three Oakhurst Apartments Project 2
Air Quality Assessment
stories.1 According to the General Plan Land Use Designations – City of Beverly Hills (Beverly Hills General Plan Land Use Map) and General Plan Land Use Map, Wilshire Community Plan (Los Angeles General Plan Land Use Map), the project site is currently designated Multi-Family Residential, High Density (within the portion of the lot located within the City of Beverly Hills) and High Medium Residential (within the portion of the lot located within the City of Los Angeles).2,3 The on-site designations allow for a maximum density of 50 dwelling units per acre (du/acre) within the portion of the lot located within the City of Beverly Hills and between 55 and 109 du/acre within the portion of the lot located within the City of Los Angeles.

Additionally, the portion of the lot located within the City of Beverly Hills allows for a 60-foot maximum building height. The portion of the lot located within the City of Los Angeles does not designate a maximum building height.The City of Beverly Hills portion of the lot is zoned Multiple Residential Zone (R4) and the City of Los Angeles portion of the lot is zoned Qualified Classification, Multiple Dwelling Zone, Height District No. 1, Oil Drilling District ([Q]R4-1-O).

Surrounding uses adjacent to the project site include residential land uses. The project site is located within walking distance of single-family homes, condominiums and apartments, as well as offices, retail stores, restaurants, and other commercial businesses along Beverly Boulevard.

PROJECT DESCRIPTION
The proposed project would involve demolishing the existing 15-unit multi-family residential building and associated parking garage and constructing a new multi-family residential (apartment) building (up to eight stories in height), landscaping, open space, and two levels of basement parking; refer to Exhibit 3, Site Plan. The building would include 52 residential units (12 residential units within the City of Beverly Hills and 40 units within the City of Los Angeles). The residential unit options would include studios through three-bedroom units. The proposed building would include common open space amenities including: a trash room, recycling room, mail room, and long-term bicycle storage room located on the first floor; a bicycle parking/maintenance room and a landscaped outdoor courtyard located on the second floor; a recreation room located on the third floor; a gym located on the fourth floor; and common space located on the fifth floor. The rooftop would include screened mechanical equipment and an area reserved for future solar panel use. Ancillary facilities, such as an elevator lobby, elevators, and stairs are also proposed.

The two basement parking levels would accommodate 66 standard parking spaces (18 standard spaces within the City of Beverly Hills and 48 standard spaces within the City of Los Angeles). Bicycle parking/storage, various utility related rooms (i.e., mechanical and electrical), and storage facilities would also be located on the basement levels. Total parking spaces, including parking at grade within the City of Los Angeles, would be 75.

Air Quality Assessment
Construction activities would include demolition, grading, building construction, and the application of architectural coatings. Construction activities and would occur over approximately 32 months, beginning in approximately October 2025 and ending May 2028. The proposed earthwork would result in approximately 19,000 cubic yards of soil export and demolition of approximately 32,400-gross square feet of an existing residential building.

CRITERIA AIR POLLUTANTS
Air quality is a general description of how levels of air pollution and other atmospheric conditions can affect public health and the environment. Under the Federal Clean Air Act (FCAA), the U.S. Environmental Protection Agency (EPA) has identified six air pollutants that are environmentally prevalent and produced by human activities to be of concern with respect to health, the environment and welfare of the public.

These specific pollutants, known as criteria air pollutants, are pollutants for which the federal and state governments have established ambient air quality standards—or criteria—for outdoor concentrations to protect public health. These pollutants are common byproducts of human activities and have been documented through scientific research to cause various adverse health effect outcomes. The federal ambient concentration criteria are known as the National Ambient Air Quality Standards (NAAQS), and the California ambient concentration criteria are referred to as the California Ambient Air Quality Standards (CAAQS). The criteria air pollutants regulated at the federal jurisdiction include carbon monoxide (CO), ground-level ozone (O3), nitrogen dioxide (NO2), respirable particulate matter ten microns or less in diameter (PM10), fine particulate matter 2.5 microns or less in diameter (PM2.5), sulfur dioxide (SO2), and lead (Pb).

Carbon Monoxide (CO). CO is an odorless, colorless toxic gas that is emitted by mobile and stationary sources as a result of incomplete combustion of hydrocarbons or other carbon-based fuels. In cities, automobile exhaust can cause as much as 95 percent of all CO emissions. CO replaces oxygen in the body’s red blood cells. Individuals with a deficient blood supply to the heart, patients with diseases involving heart and blood vessels, fetuses (unborn babies), and patients with chronic hypoxemia (oxygen deficiency) as seen in high altitudes are most susceptible to the adverse effects of CO exposure. People with heart disease are also more susceptible to developing chest pains when exposed to low levels of CO.

Ozone (O3). O3 occurs in two layers of the atmosphere. The layer surrounding the earth’s surface is the troposphere. The troposphere extends approximately 10 miles above ground level, where it meets the second layer, the stratosphere. The stratospheric (the “good” O3 layer) extends upward from about 10 to 30 miles and protects life on earth from the sun’s harmful ultraviolet rays. “Bad” O3 is a photochemical pollutant, and needs volatile organic compounds (VOCs), nitrogen oxides (NOX), and sunlight to form; therefore, VOCs and NOX are O3 precursors. To reduce O3 concentrations, it is necessary to control the emissions of these O3 precursors. Significant O3 formation generally requires an adequate amount of precursors in the atmosphere and a period of several hours in a stable atmosphere with strong sunlight.

High O3 concentrations can form over large regions when emissions from motor vehicles and stationary sources are carried hundreds of miles from their origins.

While O3 in the upper atmosphere (stratosphere) protects the earth from harmful ultraviolet radiation, high concentrations of ground-level O3 (in the troposphere) can adversely affect the human respiratory system and other tissues. O3 is a strong irritant that can constrict the airways, forcing the respiratory system to work hard to deliver oxygen. Individuals exercising outdoors, children, and people with preexisting lung disease such as asthma and chronic pulmonary lung disease are considered to be the most susceptible to the health effects of O3. Short-term exposure (lasting for a few hours) to O3 at elevated Oakhurst Apartments Project 7
Air Quality Assessment
levels can result in aggravated respiratory diseases such as emphysema, bronchitis and asthma, shortness of breath, increased susceptibility to infections, inflammation of the lung tissue, increased fatigue, as well as chest pain, dry throat, headache, and nausea.

Nitrogen Dioxide (NO2). NOX are a family of highly reactive gases that are a primary precursor to the formation of ground-level O3 and react in the atmosphere to form acid rain. NO2 (often used interchangeably with NOX) is a reddish-brown gas that can cause breathing difficulties at elevated levels.

Peak readings of NO2 occur in areas that have a high concentration of combustion sources (e.g., motor vehicle engines, power plants, refineries, and other industrial operations). NO2 can irritate and damage the lungs and lower resistance to respiratory infections such as influenza. The health effects of short-term exposure are still unclear. However, continued or frequent exposure to NO2 concentrations that are typically much higher than those normally found in the ambient air may increase acute respiratory illnesses in children and increase the incidence of chronic bronchitis and lung irritation. Chronic exposure to NO2 may aggravate eyes and mucus membranes and cause pulmonary dysfunction.

Coarse Particulate Matter (PM10). PM10 refers to suspended particulate matter, which is smaller than 10 microns or ten one-millionths of a meter. PM10 arises from sources such as road dust, diesel soot, combustion products, construction operations, and dust storms. PM10 scatters light and significantly reduces visibility. In addition, these particulates penetrate into lungs and can potentially damage the respiratory tract. On June 19, 2003, the California Air Resources Board (CARB) adopted amendments to the statewide 24-hour particulate matter standards based upon requirements set forth in the Children’s Environmental Health Protection Act (Senate Bill 25). Exposure to PM10 would result in particles being deposited on the lung surface, causing tissue damage, lung inflammation, and impacting respiratory and cardiovascular health.

Fine Particulate Matter (PM2.5). Due to recent increased concerns over health impacts related to fine particulate matter (particulate matter 2.5 microns in diameter or less), both State and Federal PM2.5 standards have been created. Particulate matter impacts primarily affect infants, children, the elderly, and those with pre-existing cardiopulmonary disease. In 1997, the EPA announced new PM2.5 standards.

Industry groups challenged the new standard in court and the implementation of the standard was blocked. However, upon appeal by the EPA, the United States Supreme Court reversed this decision and upheld the EPA’s new standards.

On January 5, 2005, the EPA published a Final Rule in the Federal Register that designates the South Coast Air Basin (Basin) as a nonattainment area for Federal PM2.5 standards. On June 20, 2002, CARB adopted amendments for statewide annual ambient particulate matter air quality standards. These standards were revised/established due to increasing concerns by CARB that previous standards were inadequate, as almost everyone in California is exposed to levels at or above the current State standards during some parts of the year, and the statewide potential for significant health impacts associated with particulate matter exposure was determined to be large and wide-ranging. On July 8, 2016, EPA made a finding that the Basin has attained the 1997 24-hour and annual PM2.5 standards based on 2011-2013 data. However, the Basin remains in nonattainment as the EPA has not determined that California has met the FCAA requirements for redesignating the Basin nonattainment area to attainment.

Due to the size of PM2.5, these particles are more likely to be inhaled and deposited in the deeper parts of the lungs. Short-term exposure (up to 24 hours) would result in chronic bronchitis, asthma attacks, respiratory symptoms, and premature mortality.

Oakhurst Apartments Project 8
Air Quality Assessment
Sulfur Dioxide (SO2). Sulfur dioxide (SO2) is a colorless, irritating gas with a rotten egg smell; it is formed primarily by the combustion of sulfur-containing fossil fuels. Sulfur dioxide is often used interchangeably with SOX. Exposure of a few minutes to low levels of SO2 can result in airway constriction in some asthmatics.

Volatile Organic Compounds (VOC). VOCs are hydrocarbon compounds (any compound containing various combinations of hydrogen and carbon atoms) that exist in the ambient air. VOCs contribute to the formation of smog through atmospheric photochemical reactions and/or may be toxic. Compounds of carbon (also known as organic compounds) have different levels of reactivity; that is, they do not react at the same speed or do not form O3 to the same extent when exposed to photochemical processes. VOCs often have an odor, and some examples include gasoline, alcohol, and the solvents used in paints.

Exceptions to the VOC designation include carbon monoxide, carbon dioxide, carbonic acid, metallic carbides or carbonates, and ammonium carbonate. VOC is not considered a criteria pollutant; however, it is a precursor to O3, which is a criteria pollutant. VOCs are a criteria pollutant since they are a precursor to O3, which is a criteria pollutant. The terms VOC and ROG (see below) are used interchangeably.

Exposure to VOC vapors would result in eyes, nose, and throat irritation, nausea, headaches, and damage to the liver, kidney, and central nervous system.

Reactive Organic Gases (ROG). Similar to VOCs, ROGs are also precursors in forming O3 and consist of compounds containing methane, ethane, propane, butane, and longer chain hydrocarbons, which are typically the result of some type of combustion/decomposition process. Smog is formed when ROG and nitrogen oxides react in the presence of sunlight. ROGs are a criteria pollutant since they are a precursor to O3, which is a criteria pollutant. The terms ROG and VOC are used interchangeably. Exposure to ROGs would result in the same adverse health effects as VOCs.

EXISITNG SETTING
Regional Topography
The CARB divides the State into 15 air basins that share similar meteorological and topographical features.

The project site lies within the South Coast Air Basin. The Basin is a 6,600 square mile area bounded by the Pacific Ocean to the west and the San Gabriel, San Bernardino, and San Jacinto Mountains to the north and east. The Basin includes all of Orange County and the non-desert portions of Los Angeles, Riverside, and San Bernardino Counties, in addition to the San Gorgonio Pass area in Riverside County. The Basin’s terrain and geographical location (i.e., a coastal plain with connecting broad valleys and low hills) determine its distinctive climate.

The extent and severity of the air pollution problem in the Basin is a function of the area’s natural physical characteristics (weather and topography), as well as man-made influences (development patterns and lifestyle). Factors such as wind, sunlight, temperature, humidity, rainfall, and topography all affect the accumulation and/or dispersion of pollutants throughout the Basin.

Climate
The general region lies in the semi-permanent high-pressure zone of the eastern Pacific Ocean. As a result, the climate is mild, tempered by cool sea breezes. The climate consists of a semi-arid environment with mild winters, warm summers, moderate temperatures, and comfortable humidity. The typical mild Oakhurst Apartments Project 9
Air Quality Assessment
climatological pattern is interrupted infrequently by periods of extremely hot weather, winter storms, or Santa Ana winds. Precipitation is limited to a few winter storms.

The average annual temperature varies little throughout the Basin, averaging 75 degrees Fahrenheit (°F).

However, with a less pronounced oceanic influence, the eastern inland portions of the Basin show greater variability in annual minimum and maximum temperatures. All portions of the Basin have had recorded temperatures over 100°F in recent years.

Although the Basin has a semi-arid climate, the air near the surface is moist due to the presence of a shallow marine layer. Except for infrequent periods when dry, continental air is brought into the Basin by offshore winds, the ocean effect is dominant. Periods with heavy fog are frequent, and low stratus clouds, occasionally referred to as “high fog,” are a characteristic climate feature. Annual average relative humidity is 70 percent at the coast and 57 percent in the eastern part of the Basin. Precipitation in the Basin is typically nine to 14 inches annually and is rarely in the form of snow or hail due to typically warm weather. The frequency and amount of rainfall is greater in the coastal areas of the Basin.

The height of the inversion is important in determining pollutant concentration. An inversion is an increase of temperature with height. When the inversion is approximately 2,500 feet above sea level, the sea breezes carry the pollutants inland to escape over the mountain slopes or through the passes. At a height of 1,200 feet, the terrain prevents the pollutants from entering the upper atmosphere, resulting in a settlement in the foothill communities. Below 1,200 feet, the inversion puts a tight lid on pollutants, concentrating them in a shallow layer over the entire coastal basin. Usually, inversions are lower before sunrise than during the day. Mixing heights for inversions are lower in the summer and more persistent, being partly responsible for the high levels of O3 observed during summer months in the Basin. Smog in southern California is generally the result of these temperature inversions combining with coastal day winds and local mountains to contain the pollutants for long periods of time, allowing them to form secondary pollutants by reacting with sunlight. The Basin has a limited ability to disperse these pollutants due to typically low wind speeds.

The area in which the project is located offers clear skies and sunshine yet is still susceptible to air inversions. These inversions trap a layer of stagnant air near the ground, where it is then further loaded with pollutants. These inversions cause haziness, which is caused by moisture, suspended dust, and a variety of chemical aerosols emitted by trucks, automobiles, furnaces, and other sources.

The project area experiences average high temperatures of up to 75°F during the month of August, and average low temperatures of 50°F during the month of December. The area also experiences an average of up to approximately 3.4 inches of precipitation per month, with the most precipitation occurring in the month of February.
4 Local Ambient Air Quality
CARB monitors ambient air quality at approximately 250 air monitoring stations across the State. Air quality monitoring stations usually measure pollutant concentrations ten feet above ground level; therefore, air quality is often referred to in terms of ground-level concentrations.

Sensitive Receptors
Sensitive receptors are defined as facilities or land uses that include members of the population that are particularly sensitive to the effects of air pollutants, such as children, the elderly, and people with illnesses.

Examples of these sensitive receptors are residences, schools, hospitals, and daycare centers. CARB has identified the following groups of individuals as the most likely to be affected by air pollution: the elderly Oakhurst Apartments Project 11
Air Quality Assessment
over 65, children under 14, athletes, and persons with cardiovascular and chronic respiratory diseases such as asthma, emphysema, and bronchitis.

The nearest sensitive receptors to the project site are the existing multi-family residential uses located 15 feet to the north and south, and multi-family residential uses located approximately 25 feet to the east.

REGULATORY SETTING
Federal
Federal Clean Air Act
The FCAA of 1970 and the FCAA Amendments of 1971 required the EPA to establish NAAQS, which required the EPA to adopt more stringent air quality standards or to include standards for other specific pollutants. The FCAA was amended in 1990 to address a large number of air pollutants that are known to cause or may reasonably be anticipated to cause adverse effects to human health or adverse environmental effects. A total of 188 specific pollutants and chemical groups were initially identified as hazardous air pollutants, and the list has been modified over time. The FCAA Amendments included new regulatory programs to control acid deposition and regulate the issuance of stationary source operating permits. These standards identify levels of air quality for “criteria” pollutants that are considered the maximum levels of ambient (background) air pollutants considered safe, with an adequate margin of safety, to protect the public health and welfare; refer to Table 2, National and California Ambient Air Quality Standards.

State
California Clean Air Act
Clean Air Act permitting in California is the shared responsibility of the CARB, its 35 air pollution control agencies (districts), and EPA Region 9. Generally, CARB plays an oversight role for permitting and does not issue any pre-construction or operating permits. However, the State agency provides significant support to agencies that need permitting assistance.

California Air Resource Board
CARB administers the air quality policy in California. The CAAQS were established in 1969 pursuant to the Mulford-Carrell Act. These standards, shown with the NAAQS in Table 2, are generally more stringent and apply to more pollutants than the NAAQS. In addition to the criteria pollutants, CAAQS have been established for visibility reducing particulates, hydrogen sulfide, and sulfates. The California Clean Air Act (CCAA), which was approved in 1988, requires that each local air district prepare and maintain an Air Quality Management Plan (AQMP) to achieve compliance with the CAAQS. These AQMPs also serve as the basis for the preparation of the State Implementation Plan (SIP) for the State of California.

Like the EPA, CARB also designates areas within California as either attainment or non-attainment for each criteria pollutant based on whether the CAAQS have been achieved. Under the CCAA, areas are designated as non-attainment for a pollutant if air quality data show that a State standard for the pollutant was violated at least once during the previous three calendar years. Exceedances that are affected by highly Oakhurst Apartments Project 12
Air Quality Assessment
irregular or infrequent events are not considered violations of a State standard and are not used as a basis for designating areas as non-attainment.

1. California standards for ozone, carbon monoxide (except 8-hour Lake Tahoe), sulfur dioxide (1- and 24-hour), nitrogen dioxide, and particulate matter (PM10, PM2.5, and visibility reducing particles), are values that are not to be exceeded. All others are not to be equaled or exceeded. California ambient air quality standards are listed in the Table of Standards in Section 70200 of Title 17 of the California Code of Regulations.

2. National standards (other than ozone, particulate matter, and those based on annual arithmetic mean) are not to be exceeded more than once a year. The ozone standard is attained when the fourth highest 8-hour concentration measured at each site in a year, averaged over three years, is equal to or less than the standard. For PM10, the 24-hour standard is attained when the expected number of days per calendar year with a 24-hour average concentration above 150 μg/m3 is equal to or less than one. For PM2.5, the 24-hour standard is attained when 98 percent of the daily concentrations, averaged over three years, are equal to or less than the standard.

3. Concentration expressed first in units in which it was promulgated. Equivalent units given in parentheses are based upon a reference temperature of 25°C and a reference pressure of 760 torr. Most measurements of air quality are to be corrected to a reference temperature of 25°C and a reference pressure of 760 torr; ppm in this table refers to ppm by volume, or micromoles of pollutant per mole of gas.

4. National Primary Standards: The levels of air quality necessary, with an adequate margin of safety, to protect the public health.

5. To attain the 1-hour national standard, the 3-year average of the annual 98th percentile of the 1-hour daily maximum concentrations at each site must not exceed 100 ppb. Note that the national 1-hour standard is in units of parts per billion (ppb). California standards are in units of parts per million (ppm). To directly compare the national 1-hour standard to the California standards the units can be converted from ppb to ppm. In this case, the national standard of 100 ppb is identical to 0.100 ppm.

6. On June 2, 2010, a new 1-hour SO2 standard was established, and the existing 24-hour and annual primary standards were revoked. To attain the 1-hour national standard, the 3-year average of the annual 99th percentile of the 1-hour daily maximum concentrations at each site must not exceed 75 ppb. The 1971 SO2 national standards (24-hour and annual) remain in effect until one year after an area is designated for the 2010 standard, except that in areas designated nonattainment for the 1971 standards, the 1971 standards remain in effect until implementation plans to attain or maintain the 2010 standards are approved. Note that the 1-hour national standard is in units of ppb. California standards are in units of parts per million (ppm). To directly compare the 1-hour national standard to the California standard the units can be converted to ppm. In this case, the national standard of 75 ppb is identical to 0.075 ppm.

7. CARB has identified lead and vinyl chloride as ‘toxic air contaminants’ with no threshold level of exposure for adverse health effects determined. These actions allow for the implementation of control measures at levels below the ambient concentrations specified for these pollutants.

8. The national standard for lead was revised on October 15, 2008, to a rolling 3-month average. The 1978 lead standard (1.5 μg/m3 as a quarterly average) remains in effect until one year after an area is designated for the 2008 standard, except that in areas designated nonattainment for the 1978 standard, the 1978 standard remains in effect until implementation plans to attain or maintain the 2008 standard are approved.

9. In 1989, CARB converted both the general statewide 10-mile visibility standard and the Lake Tahoe 30-mile visibility standard to instrumental equivalents, which are “extinction of 0.23 per kilometer” and “extinction of 0.07 per kilometer” for the statewide and Lake Tahoe Air Basin standards, respectively.

Air Quality Assessment
Regional
South Coast Air Quality Management District
The SCAQMD is one of California’s 35 air quality management districts that have prepared AQMPs to accomplish a five-percent annual reduction in air emissions. SCAQMD adopted the 2022 AQMP on December 2, 2022. The primary purpose of the 2022 AQMP is to identify, develop, and implement strategies and control measures to meet the 2015 eight-hour ozone NAAQS – 70 parts per billion (ppb) as expeditiously as practicable, but no later than the statutory attainment deadline of August 3, 2038, for the Basin and August 3, 2033, for the Riverside County portion of the Salton Sea Air Basin. The 2022 AQMP incorporates the recently adopted Southern California Association of Governments’ (SCAG) 2020-2045 Regional Transportation Plan/Sustainable Communities Strategy (2020-2045 RTP/SCS) and motor vehicle emissions from CARB. The 2022 AQMP relies on a multi-level partnership of governmental agencies at the Federal, State, regional, and local level. These agencies (EPA, CARB, local governments, SCAG, and the SCAQMD) are the primary agencies that implement the AQMP programs.

Southern California Association of Governments
On September 3, 2020, the Regional Council of SCAG formally adopted the 2020-2045 RTP/SCS. The SCS portion of the 2020-2045 RTP/SCS highlights strategies for the region to reach the regional target of reducing greenhouse gases (GHGs) from autos and light-duty trucks by 8 percent per capita by 2020, and 19 percent by 2035 (compared to 2005 levels). Specially, these strategies are:
• Focus growth near destinations and mobility options;
• Promote diverse housing choices;
• Leverage technology innovations;
• Support implementation of sustainability policies; and • Promote a green region.

Furthermore, the 2020-2045 RTP/SCS discusses a variety of land use tools to help achieve the statemandated reductions in GHG emissions through reduced per capita VMT. Some of these tools include center-focused placemaking, focusing on priority growth areas, job centers, transit priority areas, as well as high quality transit areas and green regions.

The latest 2024-2050 RTP/SCS (Connect SoCal 2024) was adopted on April 4, 2024. Connect SoCal 2024 is a vision for the future of Southern California that includes policies, strategies, and projects to advance the region's mobility, economy, and sustainability through 2050. While SCAG recently adopted the Connect SoCal 2024, the SCAQMD has not released an updated AQMP. As such, this memorandum is based off the 2022 AQMP and the RTP/SCS that was adopted at the time, the 2020-2045 RTP/SCS.

Air Pollutant Emissions Thresholds
Under CEQA, the SCAQMD is an expert agency on air quality within its jurisdiction or impacting its jurisdiction. Under the FCAA, the SCAQMD has adopted Federal attainment plans for O3 and PM10. The SCAQMD reviews projects to ensure they do not: (1) cause or contribute to any new violation of any air quality standard; (2) increase the frequency or severity of any existing violation of any air quality standard; Oakhurst Apartments Project 14
Air Quality Assessment
or (3) delay timely attainment of any air quality standard or any required interim emission reductions or other milestones of any Federal attainment plan.

The CEQA Air Quality Handbook also provides significance thresholds for both construction and operation of projects within the SCAQMD’s jurisdiction. If the SCAQMD thresholds are exceeded, a potentially significant impact could result. However, ultimately the lead agency determines the thresholds of significance for impacts. If a project proposes development in excess of the established thresholds, as outlined in Table 3, South Coast Air Quality Management District Emissions Thresholds, a significant air quality impact may occur, and additional analysis is warranted to fully assess the significance of impacts.

Local Carbon Monoxide Standards
A project would result in a local air quality impact if the project results in increased traffic volumes and/or decreases in level of service (LOS) that would result in an exceedance of the CO ambient air quality standards of 20 parts per million (ppm) for 1-hour CO concentration levels, and 9 ppm for 8-hour CO concentration levels. If the CO concentrations at potentially impacted intersections with the project are lower than the standards, then there is no significant impact. If future CO concentrations with the project are above the standard, then the project would have a significant local air quality impact.

Localized Significance Thresholds
Localized significance thresholds (LSTs) were developed in response to SCAQMD Governing Boards’ Environmental Justice Enhancement Initiative (I-4). The SCAQMD provided the Final Localized Significance Threshold Methodology (dated July 2008) for guidance. The LST methodology assists lead agencies in analyzing localized impacts associated with site-specific projects. The SCAQMD provides the LST lookup tables for one-, two-, and five-acre projects emitting CO, NOX, PM2.5, or PM10. The LST methodology and associated mass rates are not designed to evaluate localized impacts from mobile sources traveling over the roadways. The SCAQMD recommends that any project over five acres should perform air quality dispersion modeling to assess impacts to nearby sensitive receptors.

CALIFORNIA ENVIRONMENTAL QUALITY ACT THRESHOLDS
In accordance with the California Environmental Quality Act Guidelines(CEQA Guidelines), project impacts are evaluated to determine whether significant adverse environmental impacts would occur. This analysis will focus on the project’s potential impacts and provide mitigation measures, if required, to reduce or avoid any potentially significant impacts that are identified. According to Appendix G of the CEQA Guidelines, the proposed project would have a significant impact related to air quality if it would:
• Conflict with or obstruct implementation of the applicable air quality plan (refer to Impact Statement AQ-1);
• Result in a cumulatively considerable net increase of any criteria pollutant for which the project region is in non-attainment under an applicable Federal or State ambient air quality standard (refer to Impact Statement AQ-2);
• Expose sensitive receptors to substantial pollutant concentrations (refer to Impact Statement AQ-3); and/or
• Result in other emissions (such as those leading to odors) adversely affecting a substantial number of people (refer to Impact Statement AQ-4).

Methodology
Construction
Project construction would primarily generate temporary criteria pollutants from construction equipment operation on-site and construction worker vehicle trips to and from the project site, and from construction material deliveries to and from the project site. Construction input data for CalEEMod include, but are not limited to, (1) the anticipated start and finish dates of construction activity; (2) inventories of construction equipment to be used; and (3) areas to be excavated and graded. Construction emissions were quantified by estimating the types and quantity of equipment that would be used on-site during each construction phase, as provided by the model defaults. CalEEMod also estimates off-site emissions from worker, vendor, and hauling truck trips.

Construction of the proposed project is anticipated to take approximately 32 months to complete. The construction activities would include demolition, grading, building construction, and architectural coating.

The number of worker and vendor trips were based on CalEEMod defaults, and the hauling truck trips were generally based on the soil export volumes provided by the project Applicant and the building area of the existing building to be demolished; approximately 19,000 cubic yards of soil export is required for this project and the existing building to be demolished is approximately 32,400 square feet. The default trip lengths were used for worker, vendor, and hauling truck trips.

Operation
Operational sources of criteria pollutant emissions include area, energy, and mobile sources, which are further discussed below. CalEEMod modeling was conducted for the proposed project condition. As a conservative analysis, emissions from existing uses on-site were not modeled or deducted from project emissions.

Oakhurst Apartments Project 18
Air Quality Assessment
Area Sources
Emissions associated with area sources include consumer products, landscape maintenance, and architectural coating. Area source emissions were calculated using standard emission rates from CARB, USEPA, SCAQMD, and CalEEMod model defaults.

Energy Sources
The project would be served by Los Angeles Department of Water and Power (LADWP). The primary use of electricity by the project would be for space heating and cooling, water heating, ventilation, lighting, appliances, landscaping equipment, and electronics. Emissions from energy sources are primarily generated by natural gas use. The emissions factors for natural gas combustion are based on EPA’s AP-42 (Compilation of Air Pollutant Emissions Factors). Emissions from electricity use are not included in the air quality analysis as they only apply to greenhouse gas emissions since electricity generation is an indirect emission generated off-site and, therefore, not relevant for local and regional air quality conditions.

Mobile Sources
Mobile source emissions are estimated by multiplying the project’s total vehicle miles traveled (VMT) by the vehicle emission factors. The vehicle emission factors were CalEEMod default values for the Los Angeles County. The project-specific VMT were calculated from project trip generation rates and CalEEMod default trip lengths. According to CalEEMod default values, the project would result in approximately 283 daily trips during weekdays, 255 trips on Saturdays, and 213 trips on Sundays.

IMPACT ANALYSIS
AQ-1 WOULD THE PROJECT CONFLICT WITH OR OBSTRUCT IMPLEMENTATION OF THE APPLICABLE AIR QUALITY PLAN?
Level of Significance: Less Than Significant Impact.

The project is located within the South Coast Air Basin, which is governed by the SCAQMD. On December 2, 2022, the SCAQMD Governing Board adopted the 2022 AQMP. The 2022 AQMP incorporates the latest scientific and technical information and planning assumptions, including the latest applicable growth assumptions, updated emission inventory methodologies for various source categories. Additionally, the 2022 AQMP utilized information and data from SCAG and its 2020-2045 RTP/SCS. While SCAG has recently adopted Connect SoCal 2024, SCAQMD has not released an updated AQMP. As such, this consistency analysis is based off the 2022 AQMP and the RTP/SCS that was adopted at the time, the 2020-2045 RTP/SCS. According to the SCAQMD’s CEQA Air Quality Handbook, projects must be analysed for consistency with two main criteria, as discussed below.

Criterion 1:

With respect to the first criterion, SCAQMD methodologies require that an air quality analysis for a project include forecasts of project emissions in relation to contributing to air quality violations and delay of attainment.

Oakhurst Apartments Project 19
Air Quality Assessment
a) Would the project result in an increase in the frequency or severity of existing air quality violations? Since the consistency criteria identified under the first criterion pertain to pollutant concentrations, rather than to total regional emissions, an analysis of a project’s pollutant emissions relative to localized pollutant concentrations associated with the CAAQS and NAAQS is used as the basis for evaluating project consistency. As discussed under Impact Statements AQ-2 and AQ-3, the project’s short-term construction emissions, long-term operational emissions, and localized concentrations of CO, NOX, PM10, and PM2.5 would be less than significant. Due to the role VOC plays in O3 formation, it is classified as a precursor pollutant and only a regional emissions threshold has been established. As such, the project would not cause or contribute to localized air quality violations or delay the attainment of air quality standard or interim emissions reductions specified in the AQMP.
b) Would the project cause or contribute to new air quality violations? As discussed in Impact Statements AQ-2 and AQ-3, construction and operation of the proposed project would result in emissions that would be below the SCAQMD construction and operational thresholds. Therefore, the proposed project would not have the potential to cause or contribute to a violation of the ambient air quality standards.
c) Would the project delay timely attainment of air quality standards or the interim emissions reductions specified in the AQMP?
As discussed in Impact Statement AQ-3, the proposed project would result in less than significant impacts regarding localized concentrations during project construction and operations. As such, the proposed project would not delay the timely attainment of air quality standards or 2022 AQMP emissions reductions.

Criterion 2:

With respect to the second criterion for determining consistency with SCAQMD and SCAG air quality policies, it is important to recognize that air quality planning within the Basin focuses on attainment of ambient air quality standards at the earliest feasible date. Projections for achieving air quality goals are based on assumptions regarding population, housing, and growth trends. Thus, the SCAQMD’s second criterion for determining project consistency focuses on whether the project exceeds the assumptions utilized in preparing the forecasts presented in the 2022 AQMP. Determining whether a project exceeds the assumptions reflected in the 2022 AQMP involves the evaluation of the following criteria. a) Would the project be consistent with the population, housing, and employment growth projections utilized in the preparation of the AQMP?

A project is consistent with the 2022 AQMP if it is consistent with the population, housing, and employment assumptions that were used in the development of the 2022 AQMP. In the case of the 2022 AQMP, foursources of data form the basis for the projections of air pollutant emissions:
the City of Beverly Hills General Plan, the City of Los Angeles General Plan, SCAG’s regional growth forecast, and the SCAG 2020-2045 RTP/SCS. The 2020-2045 RTP/SCS also provides socioeconomic forecast projections of regional population growth.

Oakhurst Apartments Project 20
Air Quality Assessment
The project site is zoned Multiple Residential Zone (R-4), and the Beverly Hills General Plan Land Use Map and Los Angeles General Plan Land Use Map currently designate the project site as MultiFamily Residential, High Density (within the portion of the lot located in the City of Beverly Hills) and High Medium Residential (within the portion of the lot located in the City of Los Angeles). The on-site designations allow for a maximum density of 50 du/acre on the portion of the lot located in the City of Beverly Hills and between 55 and 109 du/acre on the portion of the lot located in the City of Los Angeles. Additionally, the portion of the lot located in the City of Beverly Hills allows for a 60-foot maximum building height, and the portion of the lot located in the City of Los Angeles does not designate a maximum building height. The proposed project would involve demolishing the existing residential building and constructing a 52-unit (12 residential units within the portion of the lot located in the City of Beverly Hills and 40 units within the portion of the lot located in the City of Los Angeles) residential building with common open space amenities and two levels of basement parking on an approximately 0.35-acre (0.10-acre within the portion of the lot located in Beverly Hills and 0.25-acre within the portion of the lot located in Los Angeles on) site. As such, the project would result in an overall density of 149 du/acre. The proposed building would be constructed up to a height of eight stories (or 86 feet, 11 inches), including rooftop appurtenances.

The project would seek a Density Bonus Permit within the City of Beverly Hills to allow a 50 percent density bonus for projects that include an amount of very low income units equal to 15 percent of the total base density (pursuant to California Government Code Section 65915[f][2]); and an additional 38.75 percent density bonus for projects that include an amount of very low income units equal to 10 percent of the total base density (pursuant to California Government Code Section 65915[v][2]). Within the City of Los Angeles, the project Applicant requests a 50 percent density bonus for projects that include an amount of very low income units equal to 15 percent of the total base density (pursuant to California Government Code Section 65915[f][2]).

Within the City of Beverly Hills, the proposed project would include two very low-income units; one low income unit; and nine market-rate units. With the approval of the requested waiver and Density Bonus Permit, the project would be consistent with the General Plan and Zoning Map requirements.

The population estimate as of January 1, 2024, is 31,806 persons in Beverly Hills and 3,814,318 persons in Los Angeles.
7 The project would induce population growth directly through the construction of 52 residential units. Based on CalEEMod default value, the project would result in a direct population increase of approximately 154 persons. Based on the population forecast provided in the 2020-2045 RTP/SCS, Beverly Hills and Los Angeles are estimated to have approximately 35,800 residents and 4,771,300 residents, respectively, by 2045 (the 2020-2045 RTP/SCS horizon year).8 Therefore, between 2024 and 2045, Beverly Hills and Los Angeles are expected to have an estimate population growth of 3,994 residents and 956,982 residents, respectively. The project’s 154 residents would represent approximately 3.9 percent or 0.02 percent of the anticipated growth in Beverly Hills and Los Angeles, respectively. Thus, the project would be consistent with the projections in the 2020-2045 RTP/SCS. It should be noted that the 7 California Department of Finance, Population and Housing Estimates for Cities, Counties, and the State, January 2021- 2024, with 2020 Benchmark, https://dof.ca.gov/forecasting/demographics/estimates/e-5-population-and-housing-estimatesfor-cities-counties-and-the-state-2020-2024/, accessed July 9, 2024. 8 Southern California Association of Governments, Connect SoCal 2020, Demographics and Growth Forecast, https://scag.ca.gov/sites/main/files/file-attachments/0903fconnectsocal_demographics-and-growth-forecast.pdf?1606001579, accessed July 9, 2024.

Oakhurst Apartments Project 21
Air Quality Assessment
analysis above is a conservative analysis as the project’s estimated population growth of 154 persons does not take into account the existing residents on the project site. Since SCAQMD has incorporated the 2020-2045 RTP/SCS projections into the 2022 AQMP, it can be concluded that the project would also be consistent with the 2022 AQMP.

Therefore, the project is consistent with the types, intensity, and patterns of land use envisioned for the site vicinity and would be considered consistent with the General Plans upon the approvals on the required waivers and permits. Further, the population, and housing, which are adopted by SCAG’s Regional Council, are based on the local plans and policies applicable to Beverly Hills and Los Angeles. As the SCAQMD has incorporated these same projections into the 2022 AQMP, it can be concluded that the proposed project would be consistent with the projections. b) Would the project implement all feasible air quality mitigation measures? The proposed project would not require mitigation and would result in less than significant air quality impacts; refer to Impact Statements AQ-2 and AQ-3. In addition, the project would comply with all applicable SCAQMD rules and regulations, including Rule 403 that requires control of excessive fugitive dust emissions by regular watering or other dust prevention measures, and Rule 1113 that regulates the ROG content of paint. As such, the proposed project meets this AQMP consistency criterion.
c) Would the project be consistent with the land use planning strategies set forth in the AQMP? Land use planning strategies set forth in the 2022 AQMP are primarily based on the 2020-2045 RTP/SCS. The project is located less than 0.3-mile from multiple bus stops located along Santa Monica Boulevard and Burton Way operated by Los Angeles Metro. Further, the project would provide electric vehicle (EV) charging stations and bicycle parking on-site to promote alternative transportation options. Therefore, the project would be consistent with the actions and strategies of the 2020-2045 RTP/SCS to reduce VMT and related mobile source emissions.

In conclusion, the determination of 2022 AQMP consistency is primarily concerned with the long-term influence of a project on air quality in the Basin. The proposed project would not result in a long-term impact on the region’s ability to meet State and Federal air quality. Also, the proposed project would be consistent with the goals and policies of the 2022 AQMP for control of fugitive dust. As discussed above, the proposed project’s long-term influence would also be consistent with the SCAQMD and SCAG’s goals and policies and is, therefore, considered consistent with the 2022 AQMP.

Mitigation Measures: No mitigation is required.

AQ-2 WOULD THE PROJECT RESULT IN A CUMULATIVELY CONSIDERABLE NET INCREASE OF ANY

CRITERIA POLLUTANT FOR WHICH THE PROJECT REGION IS NON-ATTAINMENT UNDER AN APPLICABLE FEDERAL OR STATE AMBIENT AIR QUALITY STANDARD? Level of Significance: Less Than Significant Impact.

2. Modeling assumptions include compliance with SCAQMD Rule 403 which requires: properly maintain mobile and other construction equipment; replace ground cover in disturbed areas quickly; water exposed surfaces three times daily; cover stockpiles with tarps; water all haul roads twice daily; and limit speeds on unpaved roads to 15 miles per hour.

Source: Refer to Appendix A for assumptions used in this analysis.

Fugitive Dust Emissions
Construction activities are a source of fugitive dust emissions that may have a substantial, temporary impact on local air quality. In addition, fugitive dust may be a nuisance to those living and working in the project area. Fugitive dust emissions are associated with land clearing, ground excavation, cut-and-fill, and truck travel on unpaved roadways. Fugitive dust emissions vary substantially from day to day, depending on the level of activity, specific operations, and weather conditions. Fugitive dust from demolition, site preparation, and construction is expected to be short-term and would cease upon project completion. It should be noted that most of this material is inert silicates, rather than the complex organic particulates released from combustion sources, which are more harmful to health.

Dust (larger than 10 microns) generated by such activities usually becomes more of a local nuisance than a serious health problem. Of particular health concern is the amount of PM10 generated as a part of fugitive dust emissions. PM10 poses a serious health hazard alone or in combination with other pollutants.

PM2.5 is mostly produced by mechanical processes. These include automobile tire wear, industrial processes such as cutting and grinding, and re-suspension of particles from the ground or road surfaces by wind and human activities such as construction or agriculture. PM2.5 is mostly derived from combustion sources, such as automobiles, trucks, and other vehicle exhaust, as well as from stationary sources. These particles are either directly emitted or are formed in the atmosphere from the combustion of gases such as NOX and sulfur oxides (SOX) combining with ammonia. PM2.5 components from material in the earth’s crust, such as dust, are also present, with the amount varying in different locations.

Air Quality Assessment
Construction activities would comply with SCAQMD Rule 402, which prohibits fugitive dust from creating a nuisance off-site, and Rule 403, which requires that excessive fugitive dust emissions be controlled by regular watering or other dust prevention measures. Adherence to SCAQMD Rule 403 would greatly reduce PM10 and PM2.5 concentrations. It should be noted that these estimated reductions were applied in CalEEMod. As depicted in Table 4, total PM10 and PM2.5 emissions would not exceed the SCAQMD thresholds during construction. Thus, construction-related air quality impacts would be less than significant.

Construction Equipment and Worker Vehicle Exhaust
Exhaust emissions (e.g., NOx and CO) from construction activities include emissions associated with the transport of machinery and supplies to and from the project site, emissions produced on-site as the equipment is used, and emissions from trucks transporting materials to/from the site. As depicted in Table 4, construction equipment and worker vehicle exhaust emissions would be below the established SCAQMD thresholds. Therefore, air quality impacts from equipment and vehicle exhaust emissions would be less than significant.

ROG Emissions
In addition to gaseous and particulate emissions, the application of asphalt and surface coatings creates ROG emissions, which are O3 precursors. As required, all architectural coatings for the proposed project structures would comply with SCAQMD Rule 1113. Rule 1113 provides specifications on painting practices as well as regulates the ROG content of paint. ROG emissions associated with the proposed project would be less than significant; refer to Table 4.

Total Daily Construction Emissions
In accordance with the SCAQMD Guidelines, CalEEMod was utilized to model construction emissions for ROG, NOX, CO, SOX, PM10, and PM2.5. As indicated in Table 4, criteria pollutant emissions during construction of the proposed project would not exceed the SCAQMD significance thresholds. Thus, total construction related air emissions would be less than significant.

Naturally Occurring Asbestos
Asbestos is a term used for several types of naturally occurring fibrous minerals that are human health hazards when airborne. The most common type of asbestos is chrysotile, but other types such as tremolite and actinolite are also found in California. Asbestos is classified as a known human carcinogen by State, federal, and international agencies and was identified as a toxic air contaminant by CARB in 1986.

Asbestos can be released from serpentinite and ultramafic rocks when the rock is broken or crushed. At the point of release, the asbestos fibers may become airborne, causing air quality and increase the risk of asbestos-related diseases and cancer (i.e., scarring of lungs [asbestosis], pleural disease, lung cancer, and mesothelioma). These rocks have been commonly used for unpaved gravel roads, landscaping, fill projects, and other improvement projects in some localities. Asbestos may be released to the atmosphere due to vehicular traffic on unpaved roads, during grading for development projects, and at quarry operations. All of these activities may have the effect of releasing potentially harmful asbestos into the air. Natural weathering and erosion processes can act on asbestos bearing rock and make it easier for asbestos fibers to become airborne if such rock is disturbed. According to the California Department of Conservation Division of Mines and Geology, A General Location Guide for Ultramafic Rocks in California Oakhurst Apartments Project 24
Air Quality Assessment
– Areas More Likely to Contain Naturally Occurring Asbestos Report (August 2000), serpentinite and ultramafic rocks are not known to occur within the project area.9 As such, the project is not subject to naturally occurring asbestos.

It is possible that the existing on-site structure contains asbestos, otherwise known as asbestos-containing materials [ACMs]. According to SCAQMD Rule 1403 requirements, prior to the start of demolition activities, the existing structure must be surveyed for the presence of ACMs by a specialist that is certified by California Occupational Safety and Health Administration (Cal/OSHA) for ACM surveys. If ACMs are determined to be present, Rule 1403 requires that the SCAQMD be notified a minimum of 10 days before any demolition activities begin with specific details of all asbestos to be removed, start and completion dates of demolition, work practices and engineering controls to be used to contain the asbestos emissions, estimates on the amount of asbestos to be removed, the name of the waste disposal site where the asbestos will be taken, and the names and addresses of all contractors and transporters that will be involved in the asbestos removal process. Therefore, through adherence to the ACMs removal requirements, detailed in SCAQMD Rule 1403, a less than significant impact pertaining to potential ACMs would result during demolition activities.

Operations
Long-term air quality impacts typically consist of mobile source emissions generated from project-related traffic (i.e., motor vehicle use by employees, deliveries travelling to and from the site), and emissions from area and energy sources. It should be noted that, as a conservative analysis, operational emissions associated with the existing uses are not deducted from project emissions. Emissions associated with each of these sources were calculated and are discussed below. Operational emissions generated by the proposed project are detailed in Table 5, Maximum Operational Emissions.

Air Quality Assessment
Notes:

1. Emissions were calculated using CalEEMod, version 2022.1.

2. The numbers may be slightly off due to rounding.

Refer to Appendix A for assumptions used in this analysis.

Mobile Source
Mobile sources are emissions from motor vehicles, including tailpipe and evaporative emissions.

Depending upon the pollutant being discussed, the potential air quality impact may be of either regional or local concern. For example, ROG, NOX, SOX, PM10, and PM2.5 are all pollutants of regional concern (NOX and ROG react with sunlight to form O3 [photochemical smog], and wind currents readily transport SOX, PM10, and PM2.5). However, CO tends to be a localized pollutant, dispersing rapidly at the source.

Project-generated vehicle emissions have been estimated using CalEEMod. Based on CalEEMod defaults, the proposed project would generate approximately 283 daily trips during weekdays, 255 trips on Saturdays, and 213 trips on Sundays. As shown in Table 5, emissions generated by vehicle traffic associated with the project would not exceed established SCAQMD thresholds.

Area Source Emissions
Area source emissions would be generated from consumer products, architectural coatings, and landscaping. The project’s criteria pollutant emissions from area sources would not exceed the established thresholds; refer to Table 5.

Energy Source Emissions
The primary use of electricity by the project would be for space heating and cooling, water heating, ventilation, lighting, appliances, landscaping equipment, and electronics. Criteria air pollutant emissions from electricity use were not quantified since criteria pollutants emissions occur at the site of the power plant, which is off-site. The project would install high efficiency lighting, appliances, and solar ready roofs.

However, as a conservative analysis, these project design features were not accounted for in the modeling. The project’s criteria pollutant emissions would be minimal and not exceed established thresholds; refer to Table 5.

Total Operational Emissions
As shown in Table 5, the total operational emissions would not exceed the SCAQMD significance thresholds. Therefore, impacts in this regard would be less than significant.

Air Quality Health Impacts
Adverse health effects induced by criteria pollutant emissions are highly dependent on a multitude of interconnected variables (e.g., cumulative concentrations, local meteorology and atmospheric conditions, and the number and character of exposed individual [e.g., age, gender]). In particular, ozone precursors VOCs and NOx affect air quality on a regional scale. Health effects related to ozone are therefore the product of emissions generated by numerous sources throughout a region. Existing models have limited sensitivity to small changes in criteria pollutant concentrations, and, as such, translating projectgenerated criteria pollutants to specific health effects or additional days of nonattainment would produce Oakhurst Apartments Project 26
Air Quality Assessment
meaningless results. In other words, the project’s less than significant increases in regional air pollution from criteria air pollutants would have nominal or negligible impacts on human health.

As noted in the Brief of Amicus Curiae by the SCAQMD, the SCAQMD acknowledged it would be extremely difficult, if not impossible to quantify health impacts of criteria pollutants for various reasons including modeling limitations as well as where in the atmosphere air pollutants interact and form. Further, as noted in the Brief of Amicus Curiae by the San Joaquin Valley Air Pollution Control District (SJVAPCD), SJVAPCD has acknowledged that currently available modeling tools are not equipped to provide a meaningful analysis of the correlation between an individual development project’s air emissions and specific human health impacts.

The SCAQMD acknowledges that health effects quantification from ozone, as an example is correlated with the increases in ambient level of ozone in the air (concentration) that an individual person breathes.

SCAQMD’s Brief of Amicus Curiae states that it would take a large amount of additional emissions to cause a modeled increase in ambient ozone levels over the entire region. The SCAQMD states that based on their own modeling in the SCAQMD’s 2012 Air Quality Management Plan, a reduction of 432 tons (864,000 pounds) per day of NOX and a reduction of 187 tons (374,000 pounds) per day of VOCs would reduce ozone levels at highest monitored site by only nine parts per billion. As such, the SCAQMD concludes that it is not currently possible to accurately quantify ozone-related health impacts caused by NOX or VOC emissions from relatively small projects (defined as projects with regional scope) due to photochemistry and regional model limitations. As such, for the purpose of this analysis, since the project would not exceed SCAQMD thresholds for construction and operational air emissions, the project would have a less than significant impact for air quality health impacts as well.

Cumulative Conclusion
With respect to the proposed project’s construction-related air quality emissions and cumulative Basinwide conditions, the SCAQMD has developed strategies to reduce criteria pollutant emissions outlined in the 2022 AQMP pursuant to FCAA mandates. As such, the proposed project would comply with SCAQMD Rule 403 requirements and the adopted 2022 AQMP emissions control measures. Rule 403 requires that fugitive dust be controlled with the best available control measures in order to reduce dust so that it does not remain visible in the atmosphere beyond the property line of the proposed project. Per SCAQMD rules and mandates, as well as the CEQA requirement that significant impacts be mitigated to the extent feasible, these same requirements (i.e., Rule 403 compliance, the implementation of all feasible mitigation measures, and compliance with adopted 2022 AQMP emissions control measures) would also be imposed on construction projects throughout the Basin, which would include related projects.

According to the SCAQMD CEQA Air Quality Handbook, project-related emissions that fall below the established construction and operational thresholds should be considered less than significant unless there is pertinent information to the contrary. As discussed previously, the proposed project would not result in short- or long-term air quality impacts, as emissions would not exceed the SCAQMD adopted construction or operational thresholds. Additionally, adherence to SCAQMD rules and regulations would alleviate potential impacts related to cumulative conditions on a project-by-project basis. As a result, the proposed project would not contribute a cumulatively considerable net increase of any nonattainment criteria pollutant. Therefore, the project’s incremental construction and operational impacts would be less than cumulatively considerable and impacts in this regard are less than significant.

Mitigation Measures: No mitigation is required.

Oakhurst Apartments Project 27
Air Quality Assessment
AQ-3 WOULD THE PROJECT EXPOSE SENSITIVE RECEPTORS TO SUBSTANTIAL POLLUTANT CONCENTRATIONS?
Level of Significance: Less Than Significant Impact.

Sensitive receptors are defined as facilities or land uses that include members of the population that are particularly sensitive to the effects of air pollutants, such as children, the elderly, and people with illnesses.

Examples of these sensitive receptors are residences, schools, hospitals, and daycare centers. CARB has identified the following groups of individuals as the most likely to be affected by air pollution: the elderly over 65, children under 14, athletes, and persons with cardiovascular and chronic respiratory diseases such as asthma, emphysema, and bronchitis.

The nearest sensitive receptors to the project site are the existing multi-family residential uses located approximately 15 feet to the north and south, and multi-family residential uses located approximately 25 feet to the east. To identify impacts to sensitive receptors, the SCAQMD recommends addressing localized significance thresholds (LSTs) for construction and operations impacts (area sources only). The CO hotspot analysis following the LST analysis addresses localized mobile source impacts.

Localized Significance Thresholds
LSTs were developed in response to SCAQMD Governing Boards’ Environmental Justice Enhancement Initiative (I-4). The SCAQMD provided the Final Localized Significance Threshold Methodology (dated June 2003 [revised 2008]) for guidance. The LST methodology assists lead agencies in analyzing localized air quality impacts. The SCAQMD provides the LST screening lookup tables for one-, two-, and five-acre projects emitting CO, NOX, PM2.5, or PM10. The LST methodology and associated mass rates are not designed to evaluate localized impacts from mobile sources traveling over the roadways. The project is located within SRA 2, Northwest Los Angeles County Coastal.

Construction LST
The SCAQMD guidance on applying CalEEMod to LSTs specifies the number of acres a particular piece of equipment would likely disturb per day.10 SCAQMD provides LST thresholds for one-, two-, and five-acre site disturbance areas; SCAQMD does not provide LST thresholds for projects over five acres. The project would actively disturb approximately one acre per day during the grading phase of construction.

Therefore, the LST thresholds for one-acre were utilized for the construction LST analysis. The closest sensitive receptors are the existing multi-family residential uses adjacent to the north and south, approximately 15 feet away. While there are receptors to the east and west that are slightly further away, the following analysis would analyze the impacts on the nearest sensitive receptors to the north and south of the project site as a conservative analysis. These sensitive land uses may be potentially affected by air pollutant emissions generated during on-site construction activities. LST thresholds are provided for distances to sensitive receptors of 25, 50, 100, 200, and 500 meters. As the nearest sensitive uses are located approximately 15 feet from the project site, the LST values for 25 meters (82 feet) were used. It should be noted that the following analysis would also address localized air quality impacts for receptors to the east and west as they are located within 25 meters (82 feet) of the project site. 10 The number of acres represent the total acres traversed by grading equipment. To properly grade a piece of land, multiple passes with equipment may be required. The disturbance acreage is based on the equipment list and days of the grading phase according to the anticipated maximum number of acres a given piece of equipment can pass over in an 8-hour workday.

Oakhurst Apartments Project 28
Air Quality Assessment
Table 6, Localized Significance of Construction Emissions, shows the localized construction-related emissions for NOX, CO, PM10, and PM2.5 compared to the LSTs for SRA 2. It is noted that the localized emissions presented in Table 6 are less than those in Table 4 because localized emissions include only onsite emissions (i.e., from construction equipment and fugitive dust), and do not include off-site emissions (i.e., from hauling activities). As shown in Table 6, localized construction emissions would not exceed the LSTs for SRA 2. Therefore, localized significance impacts from construction would be less than significant.

Notes:

1. Maximum on-site daily emissions occur during grading phase for NOX, CO, PM10, and PM2.5 in Year 1 (2025).

2. Maximum on-site daily emissions occur during building construction phase for NOx and CO, and during grading phase for PM10 and PM2.5 in Year 2 (2026).

3. Maximum on-site daily emissions occur during building construction phase for NOX, CO, PM10, and PM2.5 in Year 3 (2027) and Year 4 (2028).

4. Modeling assumptions include compliance with SCAQMD Rule 403 which requires the following: properly maintain mobile and other construction equipment; replace ground cover in disturbed areas quickly; water exposed surfaces three times daily; cover stockpiles with tarps; water all haul roads twice daily; and limit speeds on unpaved roads to 15 miles per hour.

5. The Localized Significance Threshold Mass Rate Screening Criteria was determined using Appendix C of the SCAQMD Final Localized Significant Threshold Methodology guidance document for pollutants NOX, CO, PM10, and PM2.5. The Localized Significance Threshold was based on the anticipated daily acreage disturbance for construction (approximately one acre; therefore, the one-acre threshold was used) and Source Receptor Area 2.

Refer to Appendix A for assumptions used in this analysis.

Operational LST
According to SCAQMD LST methodology, LSTs would apply to operational activities if the project includes stationary sources or attracts mobile sources that may spend extended periods queuing and idling at the site (i.e., warehouse or transfer facilities). The proposed residential development does not include such uses. Thus, due to the lack of such emissions, no long-term LST analysis is needed. Operational LST impacts would be less than significant in this regard.

Carbon Monoxide Hotspots
CO emissions are a function of vehicle idling time, meteorological conditions, and traffic flow. Under certain extreme meteorological conditions, CO concentrations near a congested roadway or intersection may reach unhealthful levels (e.g., adversely affecting residents, school children, hospital patients, and the elderly).

The Basin is designated as an attainment/maintenance area for the federal CO standards and an Oakhurst Apartments Project 29
Air Quality Assessment
attainment area under State standards. There has been a decline in CO emissions even though vehicle miles traveled (VMT) on U.S. urban and rural roads have increased; estimated anthropogenic CO emissions have decreased 68 percent between 1990 and 2014. In 2014, mobile sources accounted for 82 percent of the nation’s total anthropogenic CO emissions. Three major control programs have contributed to the reduced per-vehicle CO emissions, including exhaust standards, cleaner burning fuels, and motor vehicle inspection/maintenance programs.

According to the SCAQMD CEQA Air Quality Handbook, a potential CO hotspot may occur at any location where the background CO concentration already exceeds 9.0 parts per million (ppm), which is the 8-hour California ambient air quality standard. As previously discussed, the site is in SRA 2. Communities within SRAs are expected to have similar climatology and ambient air pollutant concentrations. The monitoring station closest to the project site is the West Los Angeles-VA Hospital Monitoring Station located at Wilshire Boulevard and Sawtelle, Los Angeles CA 90025, which is located approximately 1.34 miles southeast of the site. The CO measurements collected by this monitoring station is representative of the background CO concentration due to its close proximity to the project. The maximum CO concentration at West Los Angeles-VA Hospital Monitoring station was measured at 1.672 ppm in 2022, refer to Table

1. Given that the background CO concentration does not currently exceed 9.0 ppm, a CO hotspot would not occur at the project site.

Additionally, a detailed CO analysis was conducted in the Federal Attainment Plan for Carbon Monoxide (CO Plan) for the SCAQMD’s 2003 Air Quality Management Plan, which is the most recent AQMP that addresses CO concentrations. The locations selected for microscale modeling in the CO Plan are worstcase intersections in the Basin and would likely experience the highest CO concentrations. Thus, CO analysis within the CO Plan is utilized in a comparison to the proposed project since it represents a worstcase scenario with heavy traffic volumes within the Basin.

Of these locations, the Wilshire Boulevard/Veteran Avenue intersection in Los Angeles experienced the highest CO concentration (4.6 ppm), which is well below the 35-ppm 1-hr CO federal standard. The Wilshire Boulevard/Veteran Avenue intersection is one of the most congested intersections in Southern California with an average daily trip (ADT) volume of approximately 100,000 vehicles per day. The Beverly Boulevard currently has traffic volumes ranging from 14,100 to 16,500 ADT.11 Even with the addition of the project’s traffic generation ranging from 213 to 283 ADT, Beverly Boulevard would not experience traffic volumes exceeding 100,000 vehicles per day. As the CO hotspots were not experienced at the Wilshire Boulevard/Veteran Avenue intersection, it can be reasonably inferred that CO hotspots would not be experienced at any intersections near the project site due to the comparatively low volume of traffic that would occur as a result of project implementation. Therefore, CO hotspot impacts would not be experienced in the project’s vicinity and a less than significant impact would occur in this regard.

Mitigation Measures: No mitigation is required.

AQ-4 WOULD THE PROJECT RESULT IN OTHER EMISSIONS (SUCH AS THOSE LEADING TO ODORS) ADVERSELY AFFECTING A SUBSTANTIAL NUMBER OF PEOPLE?
Level of Significance: Less Than Significant Impact.

Oakhurst Apartments Project 30
Air Quality Assessment
According to the SCAQMD CEQA Air Quality Handbook, land uses associated with odor complaints typically include agricultural uses, wastewater treatment plants, food processing plants, chemical plants, composting, refineries, landfills, dairies, and fiberglass molding. The proposed project does not include any uses identified by the SCAQMD as being associated with odors. As such, operation of the proposed project would not generate odors that would impact nearby receptors and a less than significant impact would occur in this regard.

However, certain odors may emanate from construction operations if diesel-powered construction equipment during the construction period for the project. These odors would be limited to the construction period and would disperse quickly; therefore, these odors would not be considered a significant impact. Construction activities associated with the project may generate detectable odors from heavy-duty equipment exhaust and architectural coatings. However, construction-related odors would be short-term in nature and cease upon project completion. In addition, the project would be required to comply with the California Code of Regulations, Title 13, sections 2449(d)(3) and 2485, which minimizes the idling time of construction equipment either by shutting it off when not in use or by reducing the time of idling to no more than five minutes. This would further reduce the detectable odors from heavy-duty equipment exhaust. The project would also comply with the SCAQMD Regulation XI, Rule 1113 – Architectural Coating, which would minimize odor impacts from ROG emissions during architectural coating. Any impacts to existing adjacent land uses would be short-term and are less than significant.

Mitigation Measures: No mitigation is required.

6. Climate Risk Detailed Report

6.1. Climate Risk Summary
Cal-Adapt midcentury 2040–2059 average projections for four hazards are reported below for your project location. These are under Representation Concentration Pathway (RCP) 8.5 which assumes GHG emissions will continue to rise strongly through 2050 and then plateau around 2100.

Climate Hazard Result for Project Location Unit
Temperature and Extreme Heat 7.73 annual days of extreme heat Extreme Precipitation 7.05 annual days with precipitation above 20 mm Sea Level Rise — meters of inundation depth
Wildfire 0.30 annual hectares burned
Temperature and Extreme Heat data are for grid cell in which your project are located. The projection is based on the 98th historical percentile of daily maximum/minimum temperatures from observed historical data (32 climate model ensemble from Cal-Adapt, 2040–2059 average under RCP 8.5). Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi.

Extreme Precipitation data are for the grid cell in which your project are located. The threshold of 20 mm is equivalent to about ¾ an inch of rain, which would be light to moderate rainfall if received over a full day or heavy rain if received over a period of 2 to 4 hours. Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi.

Sea Level Rise data are for the grid cell in which your project are located. The projections are from Radke et al. (2017), as reported in Cal-Adapt (Radke et al., 2017, CEC-500-2017-008), and consider inundation location and depth for the San Francisco Bay, the Sacramento-San Joaquin River Delta and California coast resulting different increments of sea level rise coupled with extreme storm events. Users may select from four scenarios to view the range in potential inundation depth for the grid cell. The four scenarios are: No rise, 0.5 meter, 1.0 meter, 1.41 meters Wildfire data are for the grid cell in which your project are located. The projections are from UC Davis, as reported in Cal-Adapt (2040–2059 average under RCP 8.5), and consider historical data of climate, vegetation, population density, and large (> 400 ha) fire history. Users may select from four model simulations to view the range in potential wildfire probabilities for the grid cell. The four simulations make different assumptions about expected rainfall and temperature are: Warmer/drier (HadGEM2-ES), Cooler/wetter (CNRM-CM5), Average conditions (CanESM2), Range of different rainfall and temperature possibilities (MIROC5). Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi.

Global Climate Change
California is a substantial contributor of global greenhouse gases (GHGs), emitting over 381.3 million metric tons of carbon dioxide equivalent (MTCO2e) in 2021.4 Methane (CH4) is also an important GHG that potentially contributes to global climate change. GHGs are global in their effect, which is to increase the earth’s ability to absorb heat in the atmosphere. As primary GHGs have a long lifetime in the atmosphere, accumulate over time, and are generally well-mixed, their impact on the atmosphere is mostly independent of the point of emission. Every nation emits GHGs and as a result makes an incremental cumulative contribution to global climate change; therefore, global cooperation will be required to reduce the rate of GHG emissions enough to slow or stop the human-caused increase in average global temperatures and associated changes in climatic conditions.

The impact of human activities on global climate change is apparent in the observational record. Air trapped by ice has been extracted from core samples taken from polar ice sheets to determine the global atmospheric variation of CO2, CH4, and nitrous oxide (N2O) from before the start of industrialization (approximately 1750), to over 650,000 years ago. For that period, it was found that CO2 concentrations ranged from 180 to 300 parts per million (ppm). For the period from approximately 1750 to the present, global CO2 concentrations increased from a pre-industrialization period concentration of 280 to 379 ppm in 2005, with the 2005 value far exceeding the upper end of the pre-industrial period range. As of July 2024, the highest monthly average concentration of CO2 in the atmosphere was recorded at 427 ppm.5 The Intergovernmental Panel on Climate Change (IPCC) constructed several emission trajectories of GHGs needed to stabilize global temperatures and climate change impacts. It concluded that a stabilization of GHGs at 400 to 450 ppm carbon dioxide equivalent (CO2e)6 concentration is required to keep global mean warming below 2 degrees Celsius (ᵒC), which in turn is assumed to be necessary to avoid dangerous climate change.

REGULATORY SETTING
State
Various Statewide and local initiatives to reduce the State’s contribution to GHG emissions have raised awareness that, even though the various contributors to and consequences of global climate change are not yet fully understood, global climate change is under way, and there is a real potential for severe adverse environmental, social, and economic effects in the long term.

Assembly Bill 32 (California Global Warming Solutions Act of 2006). California passed the California Global Warming Solutions Act of 2006 (AB 32; California Health and Safety Code Division 25.5, Sections 38500 - 38599). AB 32 establishes regulatory, reporting, and market mechanisms to achieve quantifiable 4 California Air Resources Board, California Greenhouse Gas Emissions for 2000 to 2021, https://ww2.arb.ca.gov/ghginventory-data, accessed July 31, 2024. 5 Scripps Institution of Oceanography, Carbon Dioxide Concentration at Mauna Loa Observatory, https://scripps.ucsd.edu/programs/keelingcurve/, accessed July 31, 2024. 6 Carbon Dioxide Equivalent (CO2e) – A metric measure used to compare the emissions from various greenhouse gases based upon their global warming potential.

Oakhurst Apartments Project
Greenhouse Gas Emissions Technical Memorandum 7
reductions in GHG emissions and establishes a cap on Statewide GHG emissions. AB 32 requires that Statewide GHG emissions be reduced to 1990 levels by 2020. AB 32 specifies that regulations adopted in response to AB 1493 should be used to address GHG emissions from vehicles. However, AB 32 also includes language stating that if the AB 1493 regulations cannot be implemented, then the California Air Resources Board (CARB) should develop new regulations to control vehicle GHG emissions under the authorization of AB 32.

Executive Order S-3-05. Executive Order S-3-05 set forth a series of target dates by which Statewide emissions of GHGs would be progressively reduced, as follows:
• By 2010, reduce GHG emissions to 2000 levels;
• By 2020, reduce GHG emissions to 1990 levels; and
• By 2050, reduce GHG emissions to 80 percent below 1990 levels.

The Executive Order directed the California Environmental Protection Agency (CalEPA) Secretary to coordinate a multi-agency effort to reduce GHG emissions to the target levels. The Secretary is required to submit biannual reports to the Governor and California Legislature describing the progress made toward the emissions targets, the impacts of global climate change on California’s resources, and mitigation and adaptation plans to combat these impacts. To comply with Executive Order S-3-05, the CalEPA Secretary created the California Climate Action Team, made up of members from various State agencies and commissions. The Climate Action Team released its first report in March 2006, which proposed to achieve the targets by building on the voluntary actions of California businesses, local governments, and communities and through State incentive and regulatory programs.

Senate Bill 32. Signed into law on September 2016, SB 32 codifies the 2030 GHG reduction target in Executive Order B-30-15 (40 percent below 1990 levels by 2030). The bill authorizes CARB to adopt an interim GHG emissions level target to be achieved by 2030.

CARB Scoping Plan. On December 11, 2008, CARB adopted the Climate Change Scoping Plan (Scoping Plan), which functions as a roadmap to achieve GHG reductions in California required by AB 32 through subsequently enacted regulations. The Scoping Plan contains the main strategies California will implement to reduce GHG emissions by 174 million metric tons (MT), or approximately 30 percent, from the State’s projected 2020 emissions level of 596 million MTCO2e under a business as usual (BAU)7 scenario. This is a reduction of 42 million MTCO2e, or almost ten percent, from 2002 to 2004 average emissions, but requires the reductions in the face of population and economic growth through 2020.

The Scoping Plan calculates 2020 BAU emissions as the emissions that would be expected to occur in the absence of any GHG reduction measures. The 2020 BAU emissions estimate was derived by projecting emissions from a past baseline year using growth factorsspecific to each of the different economic sectors (e.g., transportation, electrical power, commercial and residential, industrial, etc.). CARB used three-year average emissions, by sector, for 2002 to 2004 to forecast emissions to 2020. The measures described in the Scoping Plan are intended to reduce the projected 2020 BAU to 1990 levels, as required by AB 32. 7 “Business as Usual” refers to emissions that would be expected to occur in the absence of GHG reductions; refer to http://www.arb.ca.gov/cc/inventory/data/bau.htm. Note that there is significant controversy as to what BAU means. In determining the GHG 2020 limit, CARB used the above as the “definition.” It is broad enough to allow for design features to be counted as reductions.

Oakhurst Apartments Project
Greenhouse Gas Emissions Technical Memorandum 8
AB 32 requires CARB to update the Scoping Plan at least once every five years. CARB adopted the first major update to the Scoping Plan on May 22, 2014. The updated Scoping Plan identifies the actions California has already taken to reduce GHG emissions and focuses on areas where further reductions could be achieved to help meet the 2020 target established by AB 32. The Scoping Plan update also looks beyond 2020 toward the 2050 goal, established in Executive Order S-3-05, and observes that “a mid-term statewide emission limit will ensure that the State stays on course to meet our long-term goal.” On January 20, 2017, CARB released the proposed Second Update to the Scoping Plan, which identifies the State’s post-2020 reduction strategy. The Second Update was finalized in November 2017 and approved on December 14, 2017, and reflects the 2030 target of a 40 percent reduction below 1990 levels, set by Executive Order B-30-15 and codified by SB 32. The 2017 Scoping Plan Update establishes a new Statewide emissions limit of 260 million MTCO2e for the year 2030, which corresponds to a 40 percent decrease in 1990 levels by 2030.

On December 15, 2022, CARB released the 2022 Scoping Plan for Achieving Carbon Neutrality (2022 Scoping Plan), which identifies the strategies achieving carbon neutrality by 2045 or earlier. The 2022 Scoping Plan contains the GHG reductions, technology, and clean energy mandated by statutes. The 2022 Scoping Plan was developed to achieve carbon neutrality by 2045 through a substantial reduction in fossil fuel dependence, while at the same time increasing deployment of efficient non-combustion technologies and distribution of clean energy. The plan would also reduce emissions of short-lived climate pollutants (SLCPs) and would include mechanical CO2 capture and sequestration actions, as well as emissions and sequestration from natural and working lands and nature-based strategies. Under 2022 Scoping Plan, by 2045, California aims to cut GHG emissions by 85 percent below 1990 levels, reduce smog-forming air pollution by 71 percent, reduce the demand for liquid petroleum by 94 percent compared to current usage, improve health and welfare, and create millions of new jobs. This plan also builds upon current and previous environmental justice efforts to integrate environmental justice directly into the plan, to ensure that all communities can reap the benefits of this transformational plan.

California Building Energy Efficiency Standards (Title 24) The 2022 California Building Energy Efficiency Standards for Residential and Nonresidential Buildings (California Code of Regulations, Title 24, Part 6), commonly referred to as “Title 24,” became effective on January 1, 2023. In general, Title 24 requires the design of building shells and building components to conserve energy. The standards are updated periodically to allow consideration and possible incorporation of new energy efficiency technologies and methods. The 2022 Title 24 standards encourage efficient electric heat pumps, establish electric-ready requirements for new homes, expand solar photovoltaic and battery storage standards, strengthen ventilation standards, and more.

California Green Building Standards (CALGreen)
The 2022 California Green Building Standards Code (California Code of Regulations, Title 24, Part 11), commonly referred to as CALGreen, went into effect on January 1, 2023. CALGreen is the first-in-thenation mandatory green buildings standards code. The California Building Standards Commission developed CALGreen to meet the State’s landmark initiative Assembly Bill (AB) 32 goals, which established a comprehensive program of cost-effective reductions of GHG emissions to 1990 levels by 2020. CALGreen was developed to (1) reduce GHG emissions from buildings; (2) promote environmentally responsible, cost-effective, and healthier places to live and work; (3) reduce energy and water consumption; and (4) respond to the environmental directives of the administration. CALGreen requires that new buildings employ water efficiency and conservation, increase building system efficiencies (e.g., lighting, Oakhurst Apartments Project
Greenhouse Gas Emissions Technical Memorandum 9
heating/ventilation and air conditioning [HVAC], and plumbing fixtures), divert construction waste from landfills, and incorporate electric vehicles charging infrastructure. There is growing recognition among developers and retailers that sustainable construction is not prohibitively expensive, and that there is a significant cost-savings potential in green building practices and materials.8 Regional
2020-2045 Regional Transportation Plan/ Sustainable Communities Strategy On September 3, 2020, the Regional Council of the Southern California Association of Governments (SCAG) formally adopted the Connect SoCal: 2020-2045 Regional Transportation Plan/Sustainable Communities Strategy (2020-2045 RTP/SCS). The SCS portion of the 2020-2045 RTP/SCS highlights strategies for the region to reach the regional target of reducing GHGs from autos and light-duty trucks by 8 percent per capita by 2020, and 19 percent by 2035 (compared to 2005 levels). Specially, these strategies are to:
• Focus growth near destinations and mobility options;
• Promote diverse housing choices;
• Leverage technology innovations;
• Support implementation of sustainability policies; and • Promote a green region.

Furthermore, the 2020-2045 RTP/SCS discusses a variety of land use tools to help achieve the Statemandated reductions in GHG emissions through reduced per capita vehicle miles traveled (VMT). Some of these tools include center focused placemaking, focusing on priority growth areas, job centers, transit priority areas, as well as high quality transit areas and green regions.

The most recent 2024-2050 RTP/SCS was adopted by SCAG’s Regional Council in April 2024. The 2024- 2050 RTP/SCS outlines a vision for a more resilient and equitable future, with investment, policies, and strategies for achieving the region’s shared goals through 2050. The 2024-2050 RTP/SCS sets forth a forecasted regional development pattern which, when integrated with the transportation network, measures, and policies, will reduce GHG emissions from automobiles and light-duty trucks and achieve the GHG emissions reduction target for the region set by the CARB. In addition, the 2024-2050 RTP/SCS is supported by a combination of transportation and land use strategies that outline how the region can achieve California’s GHG-emission-reduction goals and federal Clean Air Act requirements. These are articulated in a set of Regional Strategic Investments, Regional Planning Policies, and Implementation Strategies. The Regional Planning Policies are a resource for County Transportation Commissions (CTCs) and local jurisdictions, who can refer to specific policies to demonstrate alignment with the 2024-2050 RTP/SCS when seeking resources from state or federal programs. The Implementation Strategies articulate priorities for SCAG efforts in fulfilling or going beyond the Regional Planning Policies.9 While SCAG has adopted the 2024-2050 RTP/SCS, CARB has not yet certified it or approved SCAG’s GHG emissions reduction calculations.

L.A.’s Green New Deal
The City of Los Angeles’s Sustainability pLAn was first published in 2015, formalizing a commitment to addressing the climate emergency. The plan included a series of targets and strategies across different city sectors and departments to reduce GHG emissions. The second iteration of the plan was released in 2019, called L.A.’s Green New Deal. The plan is consistent with the objectives of the Paris Climate Agreement, which commits signatories to a climate action plan to help limit global warming to 1.5 degrees Celsius above pre-industrial levels. This plan is also recognized by the CARB as a comprehensive GHG reduction plan; it points to a Community and Municipal GHG Inventory as prepared by the Department of Public Works Bureau of Sanitation (LASAN), sets GHG reduction targets, forecasts emissions and determines emissions reductions required to meet targets, and lays out a selection of strategies to meet emission reduction targets. The Green New Deal includes the following targets:
• Supply 55% renewable energy by 2025; 80% by 2036; and 100% by 2045 • Source 70% of our water locally by 2035, and capture 150,000 acre feet per year of stormwater by 2035
• Reduce building energy use per square feet for all types of buildings 22% by 2025; 34% by 2035; and 44% by 2050
• Reduce Vehicle Miles Traveled per capita by at least 13% by 2025, 39% by 2035, and 45% by 2050 Oakhurst Apartments Project
Greenhouse Gas Emissions Technical Memorandum 13
• Ensure 57% of new housing units are built within 1,500 feet of transit by 2025; and 75% by 2035 • Increase the percentage of zero emission vehicles in the city to 25% by 2025; 80% by 2035; and 100% by 2050
• Create 300,000 green jobs by 2035; and 400,000 by 2050 • Convert all city fleet vehicles to zero emission where technically feasible by 2028 • Reduce municipal GHG emissions 55% by 2025 and 65% by 2035 from 2008 baseline levels, reaching carbon neutral by 2045
City of Los Angeles Green Building Code
The Los Angeles Green Building Code (LAGBC) is based on the CALGreen Code that was developed and mandated by the State to attain consistency among the various jurisdictions within the State, reduce the building's energy and water use, reduce waste, and reduce the carbon footprint. The LAGBC is Article 9 of Chapter IX of the Los Angeles Municipal Code, and adopts by reference the 2022 CALGreen Code. The provisions of LAGBC apply to the construction of every new building, every building alteration with a building permit valuation of $200,000 or more, and every building addition, unless otherwise indicated in the LAGBC, throughout the City of Los Angeles.

Methodology
Amendments to CEQA Guidelines Section 15064.4 were adopted to assist lead agencies in determining the significance of the impacts of GHG emissions. Consistent with existing CEQA practice, Section 15064.4 gives lead agencies the discretion to determine whether to assess those emissions quantitatively or qualitatively. This section recommends certain factors to be considered in the determination of significance (i.e., the extent to which a project may increase or reduce GHG emissions compared to the existing environment; whether the project exceeds an applicable significance threshold; and the extent to which the project complies with regulations or requirements adopted to implement a plan for the reduction or mitigation of GHGs). The amendments do not establish a quantified or performance-based threshold of significance; rather, lead agencies are granted discretion to establish significance thresholds for their respective jurisdictions, including looking to thresholds developed by other public agencies or suggested by other experts, such as the California Air Pollution Control Officers Association (CAPCOA), so long as any threshold chosen is supported by substantial evidence (see CEQA Guidelines Section 15064.7(c)).

Oakhurst Apartments Project
Greenhouse Gas Emissions Technical Memorandum 14
The City of Beverly Hills and City of Los Angeles have not adopted numerical significance thresholds for assessing impacts related to GHG emissions. Similarly, the SCAQMD, CARB, or any other State or regional agency have not yet adopted a numerical significance threshold for assessing GHG emissions that is applicable to the project. Since there is no applicable adopted or accepted numerical threshold of significance for GHG emissions, the methodology for evaluating the project’s impacts related to GHG emissions focuses on its consistency with statewide, regional, and local plans adopted for the purpose of reducing and/or mitigating GHG emissions. This evaluation of consistency with such plans is the sole basis for determining the significance of the project’s GHG-related impacts on the environment.

Notwithstanding, for informational purposes, the analysis also calculates the amount of GHG emissions that would be attributable to the project using recommended air quality models, as described below. The primary purpose of quantifying the project’s GHG emissions is to satisfy State CEQA Guidelines Section 15064.4(a), which calls for a good-faith effort to describe and calculate emissions. The estimated emissions inventory is also used to determine if there would be a reduction in the project’s incremental contribution of GHG emissions as a result of compliance with regulations and requirements adopted to implement plans for the reduction or mitigation of GHG emissions.

IMPACT ANALYSIS
GHG-1: Would the project generate greenhouse gas emissions, either directly or indirectly, that may have a significant impact on the environment?
GHG-2: Would the project conflict with an applicable plan, policy or regulation adopted for the purpose of reducing the emissions of greenhouse gases?
Level of Significance: Less Than Significant Impact.

Project-Related Sources of Greenhouse Gases
The proposed project would result in direct and indirect GHG emissions. Direct project-related GHG emissions would include emissions from construction activities, area sources, mobile sources, and refrigerants, while indirect sources would include emission from energy consumption, water demand, and solid waste generation. The most recent version of the California Emissions Estimator Model (CalEEMod), version 2022.1 was used to calculate project-related GHG emissions. Project construction would consist of demolition, grading, building construction, and architectural coating and would occur during a single phase over a period of 32 months, starting in October 2025 and concluding in May 2028. The project would require approximately 19,000 cubic yards of earthwork export. It should be noted that, as a conservative analysis, operational emissions associated with the existing uses are not deducted from project emissions. Table 1, Estimated Greenhouse Gas Emissions, presents the estimated GHG emissions of the proposed project. CalEEMod outputs are contained within Appendix A, Greenhouse Gas Emissions Data.

2. Totals may be slightly off due to rounding.

Refer to Appendix A for assumptions used in this analysis.

Direct Project-Related Source of Greenhouse Gases
Construction Emissions. Construction GHG emissions are amortized (i.e., total construction emissions divided by the lifetime of the project, assumed to be 30 years), 12 then added to the operational emissions.

As seen in Table 1, construction of the proposed project would result in a total of 28.96 MTCO2e per year when amortized over 30 years. This would represent a total of approximately 869 MTCO2e from all construction activities.

Area Source. Area source emissions were calculated using CalEEMod and project-specific land use data.

Project-related area sources include exhaust emissions from landscape maintenance equipment, such as lawnmowers, shedders/grinders, blowers, trimmers, chain saws, and hedge trimmers used to maintain the landscaping of the site. As noted in Table 1, the proposed project would result in 16.58 MTCO2e per year of area source GHG emissions.

Mobile Source Emissions. Based on CalEEMod defaults, the project would generate approximately 283 daily trips during weekdays, 255 trips on Saturdays, and 213 trips on Sundays, which equates to approximately 280.57 MTCO2e per year of mobile source-generated GHG emissions as modeled in CalEEMod; refer to Table 1.

Refrigerants. Refrigerants are substances used in equipment for air conditioning and refrigeration. Most of the refrigerants used today are HFCs or blends thereof, which can have high GWP values. All equipment that uses refrigerants has a charge size (i.e., quantity of refrigerant the equipment contains), and an operational refrigerant leak rate, and each refrigerant has a GWP that is specific to that refrigerant.

CalEEMod quantifies refrigerant emissions from leaks during regular operation and routine servicing over 12 In accordance with the SCAQMD guidance, projected GHGs from construction have been quantified and amortized over 30 years, which is the number of years considered to represent the life of the project. The amortized construction emissions are added to the annual average operational emissions.

the equipment lifetime, and then derives average annual emissions from the lifetime estimate. Project’s operation primarily includes air conditioning and refrigeration on-site. The project would directly result in

0.06 MTCO2e per year from refrigerants; refer to Table 1.

Indirect Project-Related Source of Greenhouse Gases
Energy Consumption. Energy consumption emissions were calculated using the CalEEMod model and project-specific land use data. Electricity and natural gas would be provided to the project site via the Los Angeles Department of Water and Power and Southern California Gas Company. The project would install high efficiency lighting, appliances, and solar ready roofs. However, as a conservative analysis, these project design features were not accounted for in the modeling. The project would indirectly result in 116.03 MTCO2e per year of GHG emissions due to energy consumption; refer to Table 1.

Water Demand. The proposed project’s operations would result in a demand of approximately 1.95 million gallons of water per year, refer to Appendix A. Emissions from indirect energy impacts due to water supply would result in 6.80 MTCO2e per year; refer to Table 1.

Solid Waste. Solid waste associated with operations of the proposed project would result in 12.01 MTCO2e per ear; refer to Table 1.

Total Project-Related Sources of Greenhouse Gases
As shown in Table 1, the total amount of proposed project-related GHG emissions from direct and indirect sources combined would total 461.01 MTCO2e per year.

Consistency with Applicable GHG Plans, Policies, or Regulations The GHG plan consistency analysis for the project is based on the project’s consistency with the SCAG’s 2020-2045 RTP/SCS, CARB’s 2022 Scoping Plan, City of Beverly Hills General Plan, Beverly Hills Sustainable City Plan, and City of Los Angeles General Plan. The 2020-2045 RTP/SCS is a regional growth management strategy that targets per-capita GHG reduction from passenger vehicles and light-duty trucks in the Southern California region. The 2020-2045 RTP/SCS incorporates local land use projections and circulation networks in city and county general plans. The 2022 Scoping Plan describes the approach California will take to reduce GHG emissions by 40 percent below 1990 levels by the year 2030. The City of Beverly Hills General Plan and City of Los Angeles General Plan contain goals and policies to reduce GHG emissions in both cities. Similarly, the Beverly Hills Sustainable City Plan (SCP) contains goals intended to support sustainable development within the City of Beverly Hills, and implementation of the SCP would contribute to a reduction in the City of Beverly Hills overall GHG emissions.

Consistency with the SCAG 2020-2045 RTP/SCS
As mentioned above, the latest 2024-2050 RTP/SCS (Connect SoCal 2024) was adopted on April 4, 2024.

However, CARB concluded that the technical methodology SCAG used to quantify the GHG emission reductions for the Connect SoCal 2024 does not operate accurately.13 SCAG resubmitted the Sustainable Communities Strategy (SCS) Submittal Package for CARB’s review in June 2024. CARB will have 60 business days to evaluate it and make its determination. Review by CARB is limited to acceptance or rejection of 13 California Air Resources Board, RE: CARB Review of Southern California Association of Governments’ 2024 SCS Senate Bill 375 Greenhouse Gas Emissions Draft Technical Methodology, March 29, 2024, https://ww2.arb.ca.gov/sites/default/files/2024-04/SCAG%20memo%20final.pdf, accessed July 31, 2024.

Oakhurst Apartments Project
Greenhouse Gas Emissions Technical Memorandum 17
SCAG’s determination that its SCS would, if implemented, achieve the region’s GHG emission reduction target. If CARB rejects SCAG’s determination of meeting the GHG emission target, SCAG would need to revise the SCS or adopt an alternative planning strategy demonstrating the ability to achieve the target.

As such, until CARB makes the decision, Connect SoCal 2024 is not a fully adopted document and is potentially subject to further updates, especially from the GHG reduction perspective of the methods and assumptions of the calculation of Auto Operating Costs (AOC)14, induced travel, electric vehicle incentives, job center parking and parking deregulation, off-model strategy assumptions, and emissions factors. As CARB has not made the decision at the time of preparation of this document, the consistency analysis relies upon the 2020-2045 RTP/SCS. Table 2¸ Consistency with the 2020-2045 RTP/SCS shows the project’s consistency with these five strategies found within the 2020-2045 RTP/SCS. As shown therein, the proposed project would be consistent with the GHG emission reduction strategies contained in the 2020- 2045 RTP/SCS.

Consistent. The proposed Project would construct a multi-family residential development near existing residential and commercial developments.

Transit Priority Areas (TPAs) are defined in the 0.5-mile radius around an existing or planned major transit stop or an existing stop along a High-Quality Transit Corridor (HQTC). A HQTC is defined as a corridor with fixed route bus service frequency of 15 minutes (or less) during peak commute hours. The project is located within an HQTC and TPA.

Additionally, the proposed project would include bicycle parking along Oakhurst Drive. This would encourage cycling as another mode of transportation. Additionally, the project is located within walking distances to existing destinations. The close proximity to existing destinations and the project’s features (reduced parking, proximity to public transit, and bicycle parking) would encourage residents and guests to use public transportation. As such, the project is consistent with this strategy.

neighborhoods.

Consistent. The proposed project would replace the existing multi-family residential building comprising of 15 dwelling units with a new residential building comprising of 52 dwelling units (12 units in the City of Beverly Hills and 40 units in the City of Los Angeles). As such, the proposed project would redevelop the land to accommodate new population growth within both cities. As such, the project is consistent with this strategy.
• Encourage design and transportation
options that reduce the reliance on
and number of solo car trips (this
could include mixed uses or locating

destinations).

Consistent. As discussed in the “right size” parking requirements consistency analysis below, the project would be subjected to California Government Code Section 65589.5(p)(1) which would require fewer parking spaces compared to the parking
requirements in the City of Beverly Hills and City of Los Angeles.

The reduction in parking spaces would reduce the overall number of solo car trips and promote the use of alternative modes of transportation. Specifically, the proposed project would include short- and long-term bicycle parking spaces which would encourage residents and visitors to utilize biking as an alternative mode of transportation. Additionally, the project is also located less than one mile from multiple bus stops serviced by the Los Angeles Metro. The project site is also located within walking distances to existing destinations such as grocery stores (Ralphs and Bristol Farms) located less than 0.1 miles to the northeast and the Beverly Center Shopping Mall less than 0.7 miles to the east.

Consistent. Pursuant to California Government Code Section 65589.5(p)(1), the maximum parking ratio that may be required of a qualifying density bonus project is one on-site parking space for each zero to one bedroom unit, one and one-half on-site parking spaces for each two- to three-bedroom unit, and two and one-half parking spaces for each four- or more bedroom unit. Within the City of Beverly Hills, the building would include: two one-bedroom units; nine two-bedroom units; and one three-bedroom unit. As such, 17 parking spaces would be required for the proposed project. The proposed project would accommodate two basement parking levels, including 18 standard parking spaces in the City of Beverly Hills.

Similarly, the portion of the project within the City of Los Angeles is subjected to California Government Code Section
65589.5(p)(1). Within the City of Los Angeles, the building would include: four studio units; seven one-bedroom units; and 29 twobedroom units. As such, 55 parking spaces would be required for the proposed project. The proposed project would accommodate two levels of basement parking levels and parking at grade comprising of 57 parking spaces. As such, the project would be consistent with parking requirements in the City of Beverly Hills and City of Los Angeles.

Not Applicable. The proposed project would not displace existing affordable housing. As such, this strategy is not applicable.

However, it should be noted that the proposed project would increase the regional housing supply and affordable housing availability. Under Senate Bill 330, cities are not permitted to replace existing residential dwelling units unless a proposed project would replace each demolish unit with a one-to-one ratio.

Additionally, replacement units must be included in the proposed housing development. The proposed project would replace the existing 15-unit multi-family building with a new residential building comprising of 52 dwelling units (12 units in the City of Beverly Hills and 40 units in the City of Los Angeles). As such, the project is consistent with Senate Bill 330. Additionally, of the 52 proposed dwelling units, the proposed project would feature three affordable housing units (two very low income units and one low income unit) within the City of Beverly Hills and five very low income units and two low income units in the City of Los Angeles. • Identify funding opportunities for new

Consistency with City of Los Angeles General Plan
As discussed above, the City of Los Angeles General Plan contains several goals related to GHG emission reduction. L.A.’s Green New Deal contains a series of targets and strategies across different city sectors and departments to reduce GHG emissions. It should be noted that all strategies included in L.A.’s Green New Deal are at the City level and do not apply to individual development projects, and therefore the project’s consistency with L.A.’s Green New Deal is not analyzed. Table 5, Consistency with Applicable Goals and Policies of the City of Los Angeles General Plan, compares the proposed project to applicable policies from the City of Los Angeles General Plan. It should be noted that the City of Beverly Hill’s decision on approving the proposed project is based on its consistency with the City of Beverly Hill’s General Plan, Sustainable City Plan, and applicable ordinances. The project’s consistency to the City of Los Angeles General Plan is provided for informational purposes only.

Goal 2: Less reliance on single-occupant vehicles with fewer commute and non-work trips.

Policy 2.2.1: Discourage single-occupant vehicle use
through a variety of measures such as market incentive
strategies, mode-shift incentives, trip reduction plans and ridesharing subsidies.

Policy 2.2.2: Encourage multi-occupant vehicle travel
and discourage single-occupant vehicle travel by
instituting parking management practices.

Consistent. Pursuant to the Los Angeles Municipal Code
Section 12.22.25(d), two options are provided regarding parking requirements for density bonus projects. Option 1 requires that one parking spaces be provided for each zero to one bedroom unit, two parking spaces for each two or three-bedroom units, and two and one-half parking spaces for each four- or more bedroom unit. However, pursuant to California Government Code Section 65589.5(p)(1) the
maximum parking ratio that may be required of a qualifying density bonus project is one on-site parking space for each zero to one bedroom unit, one and one-half on-site parking spaces for each two- to three-bedroom unit, and two and one-half parking spaces for each four- or more bedroom unit.

As such, the proposed project would have less parking than what is required in the Los Angeles Municipal Code. The reduction in parking would discourage single-occupant
vehicle travel. As previously discussed, the project is located within a TPA and HQTC which would encourage public
transit travel. As such, the project would be consistent with the goal.

air emissions by encouraging waste reduction and
recycling.

Consistent. The City of Los Angeles adopted the CalGreen Code as Los Angeles Green Building Code (LAGBC), which
requires new buildings to implement sustainability
techniques related to site development, indoor/outdoor water use, material conservation, etc. As such, the proposed
project would be designed and constructed in accordance with the sustainability techniques as outlined in the
CALGreen Code and LAGBC, in addition to those outlined in the 2022 Title 24 Standards. The project would also install energy efficient lighting and appliances, and have an area on the rooftop reserved for future solar panel use. The project would also comply with local and regional regulations and recycle or compost 75 percent of waste by 2025 pursuant to SB 1383. As such, the project would be consistent with the goal.
