According to the Certified PEIR and LUEP Addendum, Section 4.9.2, noise levels from construction activities would attenuate with distance at rate of 6 dB per doubling of distance between the noise source and the sensitive receptors. Noise levels may be attenuated an additional

3.0 to 5.0 dB by a first row of houses/buildings and 1.5 dB for each additional row of houses in built-up environments. These factors generally limit the distance construction noise travels and ensure noise impacts from construction are localized. The Certified PEIR and LUEP Addendum concluded that project construction would result in a potentially significant impact from construction noise: however, implementation of Mitigation Measures Noise-1(a) through Noise-1(b), which require specific conditions during construction activities, such as construction of temporary noise barriers and/or the use of equipment mufflers, would reduce the noise impacts to less than significant.

Construction of the proposed project would require the use of similar types of heavy-duty equipment that were considered in the Certified PEIR and LUEP Addendum (refer to the Certified PEIR, Appendix E, Table 9). However, the proposed project would not use impact pile driving methods during construction, which was considered in the Certified PEIR and LUEP Addendum.

A Noise and Vibration Impact Analysis (Noise Report) (Appendix G) was prepared by LSA (2022) for the proposed project. The Noise and Vibration Impact Analysis estimated that construction noise levels would not exceed the significance threshold at off-site noise sensitive receptors, including the residences to the east along Long Beach Boulevard, residences to the south along East 4th Street, and multi-family residences to the west across Promenade North, without implementation of Mitigation Measures Noise-1(a) and Noise-1(b) as proposed in the Certified PEIR and LUEP Addendum. Thus, project construction noise would not exceed the construction noise levels identified and disclosed in the Certified PEIR and LUEP Addendum.

In addition, although the project construction would generate periodic noise that would at times be higher than the ambient noise in the project vicinity, construction noise would cease to occur once construction is completed. Project construction would also be required to comply with the requirements of the City of Long Beach Noise Ordinance, as stated above. Compliance with the City’s Noise Ordinance would ensure project construction complies with applicable construction noise standards. Therefore, construction of the proposed project would not result in new significant impacts or a substantial increase in the severity of construction noise impacts previously identified in the Certified PEIR and LUEP Addendum. Impacts associated with construction noise would be less than significant.

Operation
The Certified PEIR and LUEP Addendum determined that noise sources typically associated with commercial land uses include mechanical equipment operations, parking lot noise (e.g., opening and closing of vehicle doors, people talking, car alarms), delivery activities (e.g., use of forklifts, hydraulic lifts), trash compactors, and air compressors. As stated in the Certified PEIR and LUEP Addendum, noise from such equipment can reach intermittent levels of approximately 90 dBA, 50 feet from the source. These elevated noise levels, which have the potential to be generated by Downtown Plan Program EIR Addendum
The Mosaic Project 106 ESA / 201801165.12
Downtown Plan Program EIR Addendum December 2022
commercial uses within mixed use land use designations, would expose nearby noise sensitive land uses (e.g., residential units) to excessive noise levels that violate the City Noise Ordinance.

Implementation of projects would be consistent with the noise associated with the development of similar land uses under the Certified PEIR and LUEP Addendum based on the type of land use development. Traffic noise would be the predominant noise source associated with development under the proposed project and would be consistent with the noise impacts identified in the Certified PEIR and LUEP Addendum. It is assumed, based on the nature of growth within the City, that new developments would be limited to a few acres or less and traffic from these developments would not be confined to one area but spread throughout the City based on the location of the new developments. Therefore, operational noise levels from projects developed under the Project would be consistent with operational noise identified in the Certified PEIR and LUEP Addendum and would not result in significant noise impacts.

Project operations would generate noise from project-related increase in roadway traffic and from mechanical equipment related to heating, ventilation and air conditioning (HVAC) operations, and parking lot noise (e.g., opening and closing of vehicle doors, people talking, car alarms). As discussed in the Noise Report, operational noise resulting from long-term traffic associated with the proposed project would result in an increase of 0.8 dBA CNEL or less over existing traffic noise conditions along The Promenade, which would not be a perceptible change in noise level. Similarly, under the future opening year, traffic noise level increases would be 0.7 dBA CNEL or less over the future opening year baseline traffic noise conditions along The Promenade. Therefore, the traffic noise increase along The Promenade resulting from the proposed project would be less than significant. As discussed in the Noise Report, mechanical equipment noise would be contained within the proposed building, and the parking area would be within the two basement levels that would be fully enclosed within the proposed project building. Therefore, noise impacts from mechanical equipment and parking areas would be less than significant. Based on the above, project operation would not result in new significant impacts or a substantial increase in the severity of operational noise impacts previously identified in the Certified PEIR and LUEP Addendum.

CONCLUSION: Same Impact as “Approved Project.” The proposed project would result in similar impacts as those identified in the Certified PEIR and LUEP Addendum; thus, impacts would be less than significant.
b) Groundborne Vibration
Construction
The Certified PEIR and LUEP Addendum determined that project construction would require the use of heavy-duty construction equipment including pile drivers (refer to the Certified PEIR, Appendix E, Table 9), which would generate vibration levels exceeding thresholds. The Certified PEIR and LUEP Addendum determined that construction vibration during implementation of the Downtown Plan would result in a potentially significant impact from ground-borne vibration of heavy construction equipment. However, the Certified PEIR and LUEP Addendum concluded that the use of administrative controls (such as scheduling construction activities with the highest potential to produce perceptible vibration to hours with least potential to affect nearby properties) would reduce perceptible vibration to a minimum. Despite these administrative controls, the Downtown Plan Program EIR Addendum
The Mosaic Project 107 ESA / 201801165.12
Downtown Plan Program EIR Addendum December 2022
Certified PEIR and LUEP Addendum determined that the use of pile-driving and other substantial vibration impact equipment (e.g., jackhammers) during construction would result in a significant and unavoidable impact.

Project construction would require the use of similar typical heavy-duty equipment construction equipment, as required in the Certified PEIR and LUEP Addendum (refer to the Certified PEIR, Appendix E, Table 9). However, the proposed project would not use impact pile driving methods during construction and instead would use pile drilling for shoring (e.g., drilled cast-in-place soldier piles). Pile drilling or displacement does not require impact equipment and generates lower vibration levels than pile driving. According to the FTA Transit Noise and Vibration Impact Assessment, vibration levels generated from construction dissipate rapidly with distance, as shown in Table 10, Vibration Source Amplitudes for Construction Equipment.

TABLE 10

VIBRATION SOURCE AMPLITUDES FOR CONSTRUCTION EQUIPMENT
Equipment Reference Peak Particle Velocity (PPV) (inches/second) 25 Feet
Hoe Ram 0.089
Caisson Drilling 0.089
Large Bulldozer 0.089
Loaded Trucks 0.076
Jackhammer 0.035
Small Bulldozer 0.003
SOURCE: FTA 2018.

As shown in Table 10, vibration levels from pile drilling or displacement, shown as caisson drilling in Table 10, generates vibration levels that are similar to large bulldozer equipment and only slightly greater than vibrations caused by loaded trucks.

The structures adjacent to or near the project site’s boundary are classified as either FTA Building Category I (reinforced-concrete, steel, or timber [no plaster]), or FTA Building Category III (nonengineered timber and masonry buildings), where the threshold for potential structural damage to Category I structures is 0.5 inches per second peak particle velocity (in/sec PPV) for continuous/frequent intermittent vibration sources. The threshold for potential structural damage to Category III structures is 0.2 in/sec PPV for continuous/frequent intermittent vibration sources. The threshold for distinctly perceptible vibration with respect to human annoyance is 78 Lv (VdB) as shown in Table D of the Noise Report prepared for the proposed project.

The nearest vibration-sensitive land use (i.e., structures) to the project site are the existing residences located to the west of the project site boundary. The maximum estimated vibration velocity level from the proposed project’s construction equipment would be up to approximately

0.021 in/sec PPV at the closest sensitive receptor, which would not exceed the 0.2 in/sec PPV Downtown Plan Program EIR Addendum
The Mosaic Project 108 ESA / 201801165.12
Downtown Plan Program EIR Addendum December 2022
significance threshold. Therefore, the on-site vibration impacts during construction of the proposed project would not exceed the significance threshold for building damage for the residential buildings. However, the parking structure to the west of the project site is located at a distance of 5 feet from the project site. The proposed project would be required to implement Mitigation Measure Noise-2 from the Certified PEIR, identified in Table 1 above. With implementation of Mitigation Measure Noise-2, which requires City review and approval for all construction projects that include potential vibration-generating activities within 100 feet of existing structures, impacts would be reduced to less than significant.

With respect to human annoyance impacts, loaded trucks and other similar equipment used during project construction would generate vibration levels up to approximately 99 VdB at the closest sensitive receptor, which would exceed the 78 VdB significance threshold. As with any type of construction, vibration levels during any phase may at times be perceptible. However, construction phases that have the highest potential of producing vibration would be intermittent and would only occur for short periods of time for any individual project site. In addition, the use of best management practices such as scheduling construction activities with the highest potential to produce perceptible vibration to hours with the least potential to affect nearby properties, perceptible vibration can be kept to a minimum. Based on the above, project construction would not result in new significant impacts or a substantial increase in the severity of construction groundborne vibration impacts previously identified in the Certified PEIR and LUEP Addendum.

Operation
The Certified PEIR and LUEP Addendum determined that operational land uses associate with development in the Downtown Plan area would not generate substantial vibrations and that any minor vibrations from on-site equipment would attenuate with distance. Vibration impacts with respect to operation would result in a less-than-significant impact.

The proposed project would not have any land uses that would generate substantial vibrations at the source. The residential uses and associated parking structure would not require any substantial machinery or equipment that would generate vibration aside from typical HVAC equipment. In addition, potential vibration impacts generated from project-related traffic on the adjacent roadways (including Long Beach Boulevard, E 4th Street, and E 6th Street for the proposed project) are unusual for on-road vehicles given that rubber tires and vehicle suspension systems provide vibration isolation. Therefore, project-related vehicular traffic on adjacent roadways would not result in significant ground-borne noise or vibration impacts and impacts would be less than significant. Therefore, project operation for the proposed project would not result in new significant impacts or a substantial increase in the severity of operational groundborne vibration impacts previously identified in the Certified and LUEP Addendum.

CONCLUSION: Less Impact than “Approved Project.” The proposed project would result in less severe impact than in the Certified PEIR and LUEP Addendum; thus, project impacts related to vibration would be less than significant with implementation of Mitigation Measure Noise-2.

c) Permanent Increase in Ambient Noise Levels
The Certified PEIR and LUEP Addendum determined that the implementation of the Downtown Plan would generate a net increase in traffic volumes, which would increase traffic noise levels directly attributable to development within the Downtown Plan area. However, noise from increased traffic from the implementation of the Downtown Plan would increase noise levels by 1 dB over future traffic noise without the proposed project, which would be less-than-significant.

The proposed project would result in a net increase in vehicular traffic to and from the project site, which would increase traffic noise levels on local roadways. Table O in the Project’s Noise Report shows that, noise from existing and future opening year traffic is expected to increase by 0.8 dBA CNEL or less along The Promenade and less along all other roadway segments evaluated in the project vicinity. A noise level increase of less than 1 dBA would not be perceptible to the human ear; therefore, the traffic noise increase along The Promenade and other roadway segments resulting from the proposed project would be less than significant. The proposed project’s increase in traffic noise along other roadway segments would be similarly low and below the level of perceptibility, given the proposed project’s low contribution to traffic.

As discussed under Issue a), above, noise sources typically associated with stationary sources that contribute to ambient noise levels from commercial land uses include mechanical equipment operations, parking lot noise (e.g., opening and closing of vehicle doors, people talking, car alarms), delivery activities (e.g., use of forklifts, hydraulic lifts), trash compactors, and air compressors. As discussed in the Noise Report prepared for the proposed project, mechanical equipment noise would be contained within the proposed building, and the parking area would be fully enclosed within the proposed project building. As a result, noise impacts from mechanical equipment and parking areas would be less than significant. Therefore, project operation would not result in new significant impacts or a substantial increase in the severity of permanent operational noise impacts previously identified in the Certified PEIR and LUEP Addendum.

The proposed project would result in operational noise consistent with what is detailed in the Certified PEIR and LUEP Addendum. Therefore, proposed project would not result in new significant impacts or a substantial increase in severity of temporary noise increase than what was identified in the Certified PEIR and LUEP Addendum.

CONCLUSION: Same Impact as “Approved Project.” The proposed project would result in similar impacts as those identified in the Certified PEIR and LUEP Addendum; thus, project impacts related to a permanent increase in ambient noise levels would be less than significant. d) Temporary Increase in Ambient Noise Levels
As discussed under Issue a), the Certified PEIR and LUEP Addendum determined that project construction would result in a temporary substantial ambient noise level increase, resulting in a potentially significant impact, requiring mitigation measures Noise-1(a) and Noise-1(b) (construction best management practices and temporary noise barriers) proposed in the Certified PEIR and LUEP Addendum to reduce construction noise levels to less-than-significant impact.

Downtown Plan Program EIR Addendum
The Mosaic Project 110 ESA / 201801165.12
Downtown Plan Program EIR Addendum December 2022
Construction under the proposed project would require the use of similar heavy duty dieselpowered equipment with high noise level characteristics, as required in the Certified PEIR.

However, the proposed project would not use pile driving methods during construction. Although construction noise would be localized to the project site and immediate vicinity during construction, noise sensitive receptors in proximity to the site could be intermittently exposed to temporary elevated levels of construction noise throughout project construction. As discussed in the Noise Report prepared for the proposed project, the estimated construction noise levels would not exceed the significance threshold at off-site noise sensitive receptors, including the residences to the west, east, and south of the project site. In addition, compliance with the City’s Noise Ordinance would ensure project construction complies with applicable construction noise standards, including hours when construction could occur. Therefore, project construction would not result in new significant impacts or a substantial increase in the severity of construction noise impacts previously identified in the Certified PEIR and LUEP Addendum.

CONCLUSION: Same Impact as “Approved Project.” The proposed project would result in similar impacts as those identified in the Certified PEIR and LUEP Addendum; thus, project impacts related to a temporary increase in ambient noise levels would be less than significant. e–f) Aircraft Noise
The Certified PEIR and LUEP Addendum determined that the Downtown Plan would not be located in proximity to an airport or airstrip and, therefore, would not be located within an Airport Land Use Compatibility Plan and would not expose workers or residents to excessive noise levels from aircraft.

The proposed project would be within the development parameters considered in the Certified PEIR and LUEP Addendum. Thus, the proposed project would not result in an impact from aircraft noise that was not previously considered in the Certified PEIR and LUEP Addendum.

Discussion
a) Population Growth
As discussed in the Certified PEIR and LUEP Addendum, the Downtown Plan is intended to accommodate substantial population growth in the Downtown Plan area with the proposed addition of 5,000 dwelling units. Based on the City average of 2.90 persons per household (City of Long Beach, 2010), the proposed Downtown Plan area’s 5,000 dwelling units would generate a net increase of approximately 14,500 new residents. The SCAG projections estimated the City’s population to grow by 6 percent from 2005 to 2015 and is anticipated to increase another 3 percent from 2015 to 2020. This represents an annual growth rate of less than 1 percent per year over the next two decades. According to the 2008 SCAG projections, the city was expected to increase in population to approximately 503,251 residents by 2010 and exceed 572,000 residents by 2035. The Downtown Plan area is expected to increase in population to approximately 70,091 residents by 2010 and nearly 80,000 residents by 2035. Thus, projected population increase in Downtown Plan is within the SCAG projections for the city. Although the area is presently zoned to permit densities of up to and exceeding 138 dwelling units per acre under the existing PD-30 zone, because implementation of the Downtown Plan would increase population growth substantially, the impact of this growth was determined to be significant and unavoidable.

The LUEP Addendum evaluated the environmental impacts of implementing the LUEP in combination with the Downtown Plan. Under the LUEP, it was determined that an additional 3,260 residential units can be accommodated by reducing office by 417,060 square feet, commercial uses by 135,320 square feet, and hotel uses by 177 rooms. This would result in an additional 9,454 residents living within the Downtown Plan area above what was evaluated in the Certified PEIR.

While exchanging retail/commercial or hotel square footage with residential square footage would increase the number of residential units and residents generated within the Downtown Plan area; however, as described in the Certified PEIR, this increase is within SCAG’s population growth projections for the City and the Downtown Plan area. Nevertheless, because implementation of the Downtown Plan, including in the LUEP, would increase population growth substantially, the impact of this growth was determined to be significant and unavoidable. Therefore, impacts were determined to remain significant and unavoidable with implementation of the LUEP in the LUEP Addendum.

Downtown Plan Program EIR Addendum
The Mosaic Project 112 ESA / 201801165.12
Downtown Plan Program EIR Addendum December 2022
The proposed project would utilize the LUEP to develop 900 residential units and 38,405 square feet of commercial space and therefore, is considered to be within the development envelope of the Certified PEIR and LUEP Addendum. The proposed 900 residential dwelling units would add approximately 2,358 residents to the population (DOF, 2022).8,9 As discussed above, the LUEP Calculator provides for an additional 3,260 housing units to be developed within the Downtown Plan area, which would exceed the 5,000 residential units and 14,500 new residents that were evaluated in the Certified PEIR. However, the floor area of office and commercial uses and the number of hotel rooms that have been approved to date are substantially lower than what was evaluated in the Certified PEIR but was evaluated in the LUEP Addendum. Thus, reallocation among the residential, commercial, office, and hotel land uses considered in the Certified PEIR can occur without a substantial change to the findings, significance determinations, and mitigation measures in the Certified PEIR.

In addition, as described above and in the PEIR and LUEP Addendum, SCAG projected the population to increase to approximately 503,251 residents by 2010 and to exceed 572,000 residents by 2035 in the city. The Downtown Plan area was expected to have a population of approximately 70,091 residents by 2010 and nearly 80,000 residents by 2035. Thus, even with the increase in population above what was evaluated in the Certified PEIR, the projected population increase in the Downtown Plan area, including from the proposed project, would still be within SCAG’s population projections for the city. In addition, the additional population growth related to the exchanging of commercial, office, and hotel uses for additional residential units has been evaluated within the LUEP Addendum. Therefore, the proposed project would not increase impacts above what was identified in the Certified PEIR and LUEP Addendum and impacts would be less than significant, which is a less severe impact than the significant and unavoidable impacts identified in the Certified PEIR and LUEP Addendum. Thus, the proposed project would not result in a new or more severe impact related to population growth than what was previously considered in the Certified PEIR and LUEP Addendum.

CONCLUSION: Less Impact than “Approved Project.” The proposed project would result in less severe impacts than the Certified PEIR and LUEP Addendum’s significant and unavoidable impact. Thus, impacts related to population growth would be less than significant with implementation of the proposed project
b–c) Household Displacement
As discussed in the Certified PEIR and LUEP Addendum, implementation of the Downtown Plan would occur over a period of 25 years or longer and would potentially result in the displacement of existing housing and people, primarily housed in medium density multifamily dwelling units.

Although new development would occur at higher densities and with more modern housing, frequently as part of a mixed-use development, residents would be displaced from their existing dwelling units and may be unable to obtain similar housing with respect to quality, price, and/or 8 Residential population calculated using information from the California Department of Finance (DOF) to provide the most recent generation rates for residential populations available. 9 900 residential units x City of Long Beach’s average household size of 2.62= 2,358 residents Downtown Plan Program EIR Addendum
The Mosaic Project 113 ESA / 201801165.12

location. Therefore, housing displacement impacts were determined to be significant and unavoidable in the Certified PEIR.

The proposed project would develop 900 residential units and 38,405 square feet of commercial space and, therefore, is considered to be within the development envelope of the Certified PEIR and LUEP Addendum. The proposed project would be developed on a site containing 197,513 square feet of existing commercial and retail uses. Therefore, the proposed project would not require the demolition of existing residential dwellings and, thus, would not result in the displacement of people or housing. Furthermore, development of the project would provide an additional 900 residential units within the Downtown Plan area, which would help to satisfy the City’s Regional Housing Needs Assessment goals. Therefore, the project would result in less-than-significant impacts related to the displacement of housing and residents. Thus, the proposed project would not result in a new or more severe impact related to the displacement of housing or resident than what was previously considered in the Certified PEIR and LUEP Addendum.

Discussion
a.i) Fire Protection
As discussed in the Certified PEIR and LUEP Addendum, fire protection services would be provided by the LBFD, which maintains 23 fire stations in addition to its headquarters near Long Beach Airport. The LBFD employs a total of 364 fire fighters with 118 suppression fire fighters on duty at all times. Additionally, structural fire suppression in the Downtown Plan area would receive response from four stations (Fire Stations 1, 2, 3, and 10) and approximately 27 firefighters (City of Long Beach, 2010). The standard established by the National Fire Protection Association for response to emergency calls is 6 minutes from call initiation to arrival on-scene of the first appropriate unit 90 percent of the time. Furthermore, the Fire Prevention Bureau reviews every new development proposal and may suggest additional fire prevention features to be included in project design. The City allocates funding to the LBFD during the annual budget process, the amount of which is based on cumulative development and the changing needs of the City. Through this process, funding for additional staffing and equipment needs would be addressed as the needs arise. Any proposed development within the Downtown Plan area would be required to pay fees pursuant to the Fire Facilities Impact Fee, as amended, in Chapter 18.23 of the LBMC. These fees would be used to finance the construction of additional fire facilities or improvements to current facilities. Therefore, provided that additional funding is provided to the LBFD as needed, new fire protection facilities would not be needed, and the Downtown Plan would not significantly affect fire protection or emergency services in the city.

The closest fire station to the project site is Fire Station 1, located approximately 0.5 mile southwest of the project site at 100 Magnolia Avenue. The proposed project’s addition of 900 residential units would increase the need for fire services at the project site. However, the project site is already developed and operating with commercial/retail uses and is currently served by Fire Station 1. The proposed project would adhere to all Fire Prevention Bureau codes and regulations, including access, sprinklers, placement of fire hydrants and fire flows, in accordance with the LBMC to minimize the risk of fires onsite. Furthermore, since the proposed project would be an urban infill development, Downtown Plan Program EIR Addendum
The Mosaic Project 115 ESA / 201801165.12
Downtown Plan Program EIR Addendum December 2022
development of the project would not expand the LBFD service area but would rather increase the residential densities in the existing service area.

In addition, the City allocates funding to the LBFD during the annual budget process, the amount of which is based on cumulative development and the changing needs of the City. Through this process, funding for additional staffing and equipment needs would be addressed as the needs arise. The proposed project would be required to pay fees pursuant to the Fire Facilities Impact Fee, as amended, in Chapter 18.16 of the LBMC. These fees would be used to finance additional resources necessary for the LBFD to maintain adequate fire service for the Downtown area. Therefore, the proposed project would result in less than significant impacts to fire service. Thus, the proposed project would not result in a new or more severe impact to fire service than what was previously considered in the certified PEIR and LUEP Addendum.

CONCLUSION: Same Impact as “Approved Project.” The proposed project would be consistent with the analysis and conclusions presented in the Certified PEIR and LUEP Addendum; thus, impacts to fire service would be less than significant with implementation of the project. a.ii) Police Protection
As discussed in the Certified PEIR and LUEP Addendum, police protection services would be provided by the Long Beach Police Department (LBPD), which maintains 40 sworn officers in the Downtown Plan area and approximately 930 sworn officers in the entire city (City of Long Beach, 2010). LBPD’s average response time for Priority One emergency calls is 4.2 minutes, meeting the target response time of 5 minutes. The Downtown Plan would incrementally increase demands on the LBPD and may require expansion facilities or replacement of existing facilities. However, as stated in the Certified PEIR and LUEP Addendum, funding for the LBPD is not tied to individual development projects. Furthermore, the City of Long Beach Department of Development Services requires the payment of development impact fees for police facilities to ensure adequate service levels are maintained as per LBMC Chapter 18.15. Therefore, provided that additional funding is provided to the LBPD to support any expanded operations, the Downtown Plan’s impact on police protection services would be less than significant.

The project site is currently developed and operating with commercial/retail uses and is served by the LBPD. The proposed project would provide 900 residential units, thereby increasing the demand for police protection services near the project site. However, the proposed project would include security features, such as lighting, cameras, and security personnel, which would help reduce the likelihood of crime on the project site. Additionally, the Police Headquarters and South Division within the Downtown Plan area is located approximately 0.4 mile southwest of the project site and is likely to deter crime within the project vicinity due to the increased presence of police officers in the area. Furthermore, since the proposed project would be an urban infill development, development of the project would not expand the LBPD service area but would rather increase the residential densities in the existing service area. Given the sufficient funding for the LBPD and timely police response times, as indicated in the Certified PEIR and LUEP Addendum, sufficient police protection services would be available to serve the project site and no new facilities would be required. As such, the proposed project would not result in a new or more severe impact to police service than what was previously considered in the Certified PEIR and LUEP Addendum.

CONCLUSION: Same Impact as “Approved Project.” The proposed project would be consistent with the analysis and conclusions presented in the Certified PEIR and LUEP Addendum; thus, impacts to police services would be less than significant with implementation of the proposed project.
a.iii) Schools
The Downtown Plan area is within the boundaries of the Long Beach Unified School District (LBUSD), which operates 52 elementary schools, 23 middle and K–8 schools, and 12 high schools.

The total district enrollment for the 2005–2006 school year was approximately 93,589 students (City of Long Beach, 2010). As discussed in the Certified PEIR, the Downtown Plan would generate an estimated 670 school-age students (370 new elementary school students, 105 new middle school students, and 195 new high school students), which could adversely affect school facilities. However, as a condition of development, each individual project within the Downtown Plan area would be required to pay the applicable required State-mandated school impact fees under the provisions of SB 50. The LUEP Addendum determined that exchanging retail/commercial or hotel square footage with residential square footage would not alter the conclusions of the Certified PEIR for schools, as future development considered under the LUEP is consistent with the density/intensity of development considered in the Certified PEIR. Furthermore, each individual project evaluated under the LUEP would also be required to pay the applicable required Statemandated school impact fees under the provisions of SB 50. Therefore, impacts to school facilities and services in the Downtown Plan area would be reduced to a less-than-significant level.

The proposed project would provide 900 additional new residential units which would generate approximately 67 new elementary school students, 19 new middle school students, and 35 new high school students, in addition to the projected amounts included in the Certified PEIR.10 However, as indicated in the LBUSD Facility Master Plan Update in 2022, LBUSD is continuing to experience a period of declining student enrollment as a result of the community’s slow growth residential population, declining birth rates, and aging population since 2003-04, resulting in excess capacity at some of the campuses (LBUSD, 2022). Additionally, the proposed project’s corresponding incremental increase in demand for schooling services would be mitigated by its contribution to the State-mandated school impact fees, which would be a condition of approval for project implementation. As discussed in the Certified PEIR and LUEP Addendum, pursuant to the provisions of SB 50, the payment of statutory fees is deemed to be full and complete mitigation of the impacts to schools. With the existing capacity and the payment of impact fees, the proposed project’s impact on school services would be less than significant. For these reasons, the proposed project would not result in a new or more severe impact to schools than what was previously considered in the Certified PEIR and LUEP Addendum.
10 According to the Certified PEIR for the Downtown Plan, 0.074 new elementary school students, 0.021 new middle school students, and 0.039 new high school students are generated with each additional residential unit. Therefore, the proposed project would add an additional 67 elementary school students (0.074 x 900 = 67); 19 middle school students (0.021 x 900 = 19); and 35 high school students (0.039 x 900 = 35).

Downtown Plan Program EIR Addendum December 2022
CONCLUSION: Same Impact as “Approved Project.” The proposed project would be consistent with the analysis and conclusions presented in the Certified PEIR and LUEP Addendum; thus, impacts schools would be less than significant with implementation of the proposed project. a.iv) Parks and Recreation
As discussed in the Certified PEIR and LUEP Addendum, the City of Long Beach is currently deficient in parkland by about 820 acres. With new development in the Downtown Plan area, the deficiency would likely increase with each subsequent project. The increased demand for recreational opportunities associated with the Downtown Plan would place additional stress on the City’s recreation system. To reduce this stress, individual project applicants within the Downtown Plan area would be required to pay an in-lieu park and recreation facilities impact fee as a condition of approval. Although the collection of required fees would mitigate some of the overburden on the recreation system, it is not expected to be enough to meet the established standard of 8 acres of parkland per 1,000 residents. Therefore, the Certified PEIR and LUEP Addendum found that the impact on park and recreation facilities from new development would be significant and unavoidable.

As discussed above, the 900 residential units and 38,405 square feet of commercial space proposed under the project is within the development envelope of the Downtown Plan Certified PEIR and LUEP Addendum. The proposed project would develop 900 residential units and, thus, could add approximately 2,358 new residents to the Downtown Plan area: thereby, increasing the demand for parks and recreation services and facilities near the project site. The project would provide 93,222 square feet of common open space, or 39 percent of the project site 11, which constitutes as public open space. The common open space provided by the project would exceed the 20 percent open space requirement of the Downtown Plan. In addition to the common open space, the proposed project would also provide 451 units with private balconies (50 percent of total units). Building B would include a pool and spa area, outdoor seating, fire pit, BBQ area, and turf fitness area; Building C1 would include a pool and spa area, outdoor seating, cabanas, fire pit, flex lawn, and BBQ area on; and Building C2 would include a pool and spa area, outdoor seating, fire pit, BBQ area, flex lawn, dog patch, and landscaping on Level 4. In addition, each building would include a roof deck that would be available for residents to use and that would include a fire pit and outdoor seating. Additionally, as discussed in the Certified PEIR and LUEP Addendum, the proposed project would be required to pay an in-lieu park and recreation facilities impact fee as a condition of approval. Therefore, no new or more severe impacts on park and recreation facilities would occur from implementation of the proposed project than what was previously considered in the Certified PEIR and LUEP Addendum.

CONCLUSION: Same Impact as “Approved Project.” The proposed project would result in less severe impacts than identified in the Certified PEIR and LUEP Addendum’s significant and unavoidable impact; thus, the proposed project’s impacts related to parks and recreation would be less than significant.
11 93,222 sf of common open space/ 239,169 sf of the project site area = 0.38977. 0. 38977 x 100 = 39% of the project site is dedicated open space.

a.v) Libraries and Other Public Facilities
The Downtown Plan area is served by the Long Beach Public Library (LBPL) system, which is staffed by approximately 250 personnel at the Main library located in Downtown and the 11 branch libraries. Buildout of the Downtown Plan would incrementally increase demand for library services in the City and may cause demands for library services to exceed the capacity of the Main Library and at branch libraries that serve the Downtown Plan area. However, as stated in the Certified PEIR and the LUEP Addendum, funding for the LBPL is not tied to individual development projects.

Therefore, provided that additional funding is provided to the LBPL to support any expanded operations, the Downtown Plan’s impact on library services would be less than significant.

As discussed above, the 900 residential units and 38,405 square feet of commercial space proposed under the project is within the development envelope of the Certified PEIR and LUEP. Consistent with the Certified PEIR and the LUEP Addendum, development of the proposed project would increase the demand for library services in the Downtown Plan area. However, as stated in the Certified PEIR and the LUEP, funding allocated to the LBPL to maintain adequate levels of service is not directly tied to individual development projects. The City has the authority to construct new facilities to serve the Downtown Plan area and, as such, the environmental impact of such construction would not be a result of individual development projects, such as the proposed project.

As such, the proposed project would result in less than significant impacts to libraries and other public facilities. Therefore, no new or more severe impacts to libraries and other public facilities would occur with development of the proposed project than what was previously considered in the Certified PEIR and LUEP Addendum.

Discussion
The discussion of potential impacts related to transportation and traffic is based on the Traffic Impact Analysis (TIA), prepared by LSA Associates, Inc. in October 2022 (Appendix H). The proposed project would be required to pay a fair-share contribution to be determined in consultation with the City to implement Mitigation Measures Traf-1(a) through Traf-1(f), identified in Table 1 above, which require improvements to specific intersections and roadways in the Downtown Plan area. CEQA Guidelines Section 15064.3 eliminated transportation delay methodologies, such as level of service (LOS), as a measure of transportation impacts effective July 1, 2020. In lieu of LOS methods, Section 15064.3 established VMT as the method for evaluating transportation impacts.

The Office of Planning and Research has advised that agencies may rely on a certified EIR before July 1, 2020, that analyzed traffic impacts using the LOS metric for analyzing transportation impacts (Office of Planning and Research, 2022).

CEQA Guidelines Section 15064.3(b)(1) also provides that generally, land use projects within onehalf mile of a major transportation stop or a stop within a high-quality transportation corridor “should be presumed to have less than significant transportation impact.” The project site is within one-half mile of the Metro A Line, which is indicated in the TIA Guidelines as a major transit stop (Appendix H). Therefore, project impacts related to transportation would be less than significant.

Downtown Plan Program EIR Addendum
The Mosaic Project 121 ESA / 201801165.12
Downtown Plan Program EIR Addendum December 2022
a) Plans, Ordinances, and Policies
The Certified PEIR identified significant impacts at 16 intersections in the Downtown Plan area.

Partial mitigation was identified to mitigate those impacts, but physical constraints at some locations made expansion of the roadway cross-sections difficult. Therefore, impacts at eight intersections were identified as significant and unavoidable. The LUEP Addendum determined that exchanging retail/commercial or hotel square footage with residential square footage would not alter the conclusions of the Certified PEIR in regard to conflicting with an applicable plan, ordinance or policy establishing measures of effectiveness for the performance of the circulation system, as future development considered under the LUEP is consistent with the density/intensity of development considered in the Certified PEIR. Thus, impacts under the LUEP would remain significant and unavoidable, similar to the Certified PEIR.

The traffic study prepared for the Certified PEIR analyzed 28 Traffic Analysis Zones (TAZ). The proposed project is located within TAZ #17, which was evaluated in the Certified PEIR and LUEP Addendum with an assumed combination of residential and office land uses that would generate a total of 374 AM peak hour trips, 500 PM peak hour trips, and 9,600 daily trips. As calculated in the TIA, the proposed project would generate a net total of 278 AM peak hour trips, 165 PM peak hour trips, and a total of 3,509 daily trips taking into consideration the existing trips generated by the existing retail and restaurant operations within the two large one-story commercial buildings. The boundaries of TAZ #17 encompass one approved project that is currently under construction (Partake Collective), which includes 9 commercial kitchens and 10 prep kitchens. Partake Collective is located at 456 Elm Avenue and is estimated to generate a total of approximately 59 AM peak hour trips, 166 PM peak hour trips, and 1,368 daily trips. With the implementation of the proposed project and other cumulative projects within TAZ #17, the traffic zone would generate a total of approximately 337 new AM peak hour trips, 331 new PM peak hour trips, and 4,877 new daily trips. Based on this data, the traffic zone would generate 37 fewer AM peak hour trips, 169 fewer PM peak hour trips, and 4,723 fewer daily trips as compared to the Certified PEIR and LUEP Addendum.

Furthermore, the TIA included an impact evaluation for the 24 intersections in the vicinity of the project site for both the Existing Condition + Project and Opening Year (2027) + Project scenarios, which included the ten intersections that were evaluated in the Traffic Study prepared for the Certified PEIR. To determine Exiting Conditions + Project traffic scenario, the TIA applied the forecasted traffic anticipated to be generated by the proposed project to existing traffic volumes at the 24 study intersections. Based on Table F within the TIA, all 24 study intersections are projected to operate an acceptable level of service (LOS) during both the a.m. and p.m. peak hours. In addition, Table G of the TIA demonstrates that the proposed project would not adversely affect the queuing lengths at the 24 study intersections under the Exiting Conditions + Project traffic scenario (Appendix H).

To determine the Opening Year (2027) + Project scenario, a 0.4 percent per year growth rate, for a total of 2 percent, was applied to the existing traffic volumes in combination with traffic generated by 40 cumulative projects and the proposed project at the 24 study intersections. As shown in Table H of the TIA, the proposed project would not adversely affect the 24 study intersections as all intersections are projected to operate at acceptable LOS during both the a.m. and p.m. peak hours.

Downtown Plan Program EIR Addendum
The Mosaic Project 122 ESA / 201801165.12
Downtown Plan Program EIR Addendum December 2022
In addition, as shown in Table I, would not adversely affect the queuing lengths at the 24 study intersections under the Exiting Conditions + Project traffic scenario (Appendix H).

In addition, as the project site is located in a low VMT residential area within one-half mile of a major transit stop and as the retail component of the proposed project is less than 50,000 square feet, the project is screened out from requiring a VMT analysis. The TIA also evaluated the project’s potential to impact alternative modes of transportation and determined that implementation of the proposed project would not be adversely affected by the project. In contrast, the proposed project would provide pedestrian/bicycle connectivity to and from the local circulation network with the offsite improvements while also increasing the safety of the motorists, pedestrians, and bicyclists. For these reasons, the proposed project would result in less than significant impacts related to conflicting with applicable transportation plans, ordinances, or policies. Therefore, no new or more severe impacts to conflicting with applicable transportation plans, ordinances, or policies would occur with development of the proposed project than what was previously considered in the Certified PEIR and LUEP Addendum.

CONCLUSION: Less Impact than “Approved Project.” The proposed project would result in less-than-significant impacts, which would be less severe impacts than the Certified PEIR and LUEP Addendum’s significant and unavoidable impact; thus, the proposed project’s impacts related to conflicting with applicable transportation plans, ordinances, or policies would be less than significant.
b) Congestion Management Programs
As noted in the Certified PEIR and LUEP Addendum, the intersections of Alamitos Avenue/7th Street and Alamitos Avenue/Ocean Boulevard are the only Downtown Plan area intersections that are designated as Congestion Management Program (CMP) arterial monitoring locations. The traffic study prepared for the Certified PEIR concluded that development of the Downtown Plan would result in a significant impact at both intersections because it would increase intersection delay by two percent or more. Considering right-of-way constraints and the potential for significant secondary impacts to pedestrians and bicyclists that could occur as a result of roadway widening, no feasible mitigation measures were identified to mitigate the significant CMP impacts. Therefore, the Certified PEIR’s CMP impacts at these intersections were identified as significant and unavoidable.

Per California Government Code Section 65088 et seq, the TIA for the proposed project did not include an analysis of CMP intersections or freeways because as of August 2019, the provisions of the CMP no longer apply to any of the 89 local jurisdictions in Los Angeles County.

CONCLUSION: Same Impact as “Approved Project.” The proposed project would be consistent with the analysis and conclusions presented in the Certified PEIR and LUEP Addendum; thus, impacts would be significant and unavoidable.
c) Air Traffic Patterns
The Certified PEIR and LUEP Addendum determined that the Downtown Plan would result in no impact to air traffic patterns.

Downtown Plan Program EIR Addendum
The Mosaic Project 123 ESA / 201801165.12
Downtown Plan Program EIR Addendum December 2022
The development of the proposed mixed-use project would not necessitate any changes in air patterns. The proposed project does not allow for development at a greater density/intensity than previously considered in the Certified PEIR and LUEP Addendum. Thus, the proposed project would not result in a new or more severe impact to air traffic patterns than what was previously considered in the Certified PEIR and LUEP Addendum.

CONCLUSION: Same Impact as “Approved Project.” The proposed project would be consistent with the analysis and conclusions presented in the Certified PEIR and LUEP Addendum; thus, no impact to changes in air traffic patterns would occur with implementation of the proposed project. d) Hazardous Design Features
The Certified PEIR and LUEP Addendum determined that the Downtown Plan would result in no impact to hazardous conditions due to a design feature or incompatible uses.

The proposed project does propose off-site improvements, which includes the closure of The Promenade North between East 4th Street and East 5th Street for pedestrian use only. However, The Promenade North is already a pedestrian paseo between East 3rd Street and East 4th Street, where the proposed project would extend the pedestrian paseo and would not affect existing roadways operation. Furthermore, the TIA found that the proposed project would increase pedestrian, bicyclists, and motorists’ safety and would not include any hazardous design features.

Therefore, the proposed project would result in less than significant impacts and would not result in a new or more severe impact related to hazardous design features than what was previously considered in the Certified PEIR or LUEP Addendum.

Vehicular access to the parking garages for Building B and Building C1 would be provided from two right-in/right-out driveways on Long Beach Boulevard and vehicular access to the parking garage for Building C2 would be provided from one right-in/right-out driveway on 6th Street. The TIA concluded that all project driveways would be forecast to operate at satisfactory levels of service during both the AM and PM peak hours and would meet the minimum sight distance requirements specified in the California Manual on Uniform Traffic Control Devices (refer to Appendix H). Pedestrian access to both the residential and commercial components of the project Downtown Plan Program EIR Addendum
The Mosaic Project 124 ESA / 201801165.12
Downtown Plan Program EIR Addendum December 2022
would be provided via building entries/exits located on the streets bordering the project site. The proposed project would not alter through-traffic operations for emergency vehicles or cause more circuitous access conditions. Development of the proposed project would alter existing street patterns as The Promenade North between East 4th Street and East 5th Street would be closed for pedestrian access only.

However, the closure of The Promenade North would not impair emergency access as The Promenade North is already a pedestrian paseo between East 3rd Street and East 4th Street, where the proposed project would extend the pedestrian paseo and would not affect existing roadways operation. In addition, the proposed project has been reviewed by the LBFD and was determined to be in compliance with emergency access requirements. No issues related to the closure of The Promenade North to vehicular traffic were identified. Furthermore, The Promenade North is not considered a major roadway and is not indicated as a City disaster route (Los Angeles County Public Works, 2013). Furthermore, any proposed development within the Downtown Plan area, including the proposed project, would be required to pay fees pursuant to the Fire Facilities Impact Fee, as amended, in Chapter 18.16 of the Long Beach Municipal Code (LBMC), as well as the Police Facilities Impact Fee as amended in Chapter 18.15 of the LBMC. Therefore, the proposed project would not result in a new or more severe impact than what was previously considered in the Certified PEIR and LUEP Addendum.

CONCLUSION: Same Impact as “Approved Project.” The proposed project would be consistent with the analysis and conclusions presented in the Certified PEIR and LUEP Addendum; thus, impacts related to emergency access would be less than significant with implementation of the project.
f) Public Transit, Bicycle, or Pedestrian Facilities
The Certified PEIR determined that the Downtown Plan would not conflict with adopted policies, plans, or programs supporting alternative transportation.

As stated above, the proposed project includes offsite improvements, which consists of, but is not limited to, the closure of The Promenade between East 4th Street and East 5th Street for pedestrian use only, dedicating sidewalks, and providing bicycle facilities. The project would provide pedestrian/bicycle connectivity to/from the local circulation network while ensuring the safety of motorists, pedestrians, and bicyclists. In addition, development of the proposed project would not affect existing operations of mass transit. Thus, the proposed project would not introduce any conflicts with adopted policies, plans, or programs supporting alternative transportation that were not previously considered in the Certified PEIR and LUEP Addendum. Project impacts would be less than significant.

Discussion
a, b, e) Wastewater
As discussed in the Certified PEIR, buildout of the Downtown Plan would incrementally increase wastewater disposal demand in the city due to the increased demand for wastewater disposal and the increase in development activity in the Downtown Plan area. However, development projects built within the Downtown Plan area would generate an estimated 2.55 million gallons per day (mgd) of wastewater per day at peak flow, which would account for approximately 0.6 percent of the combined 400 mgd design capacity of the Joint Water Pollution Control Plant (JWPCP) and the Long Beach Reclamation Plant’s (LBWRP) 25 mgd capacity. Due to sufficient capacity levels, the Certified PEIR determined that the Downtown Plan’s impacts to wastewater would be less than significant.

The proposed project would be served by the LBWD. A will serve letter for the proposed project from LBWD was received on October 4, 2022, and indicated that LBWD would have capacity to serve the project site upon the condition of approval that the LBWD sewer system is able to meet the sewer peak flows from the final designed project with minimum two weeks of sewer flow monitoring performed by the project developer (Appendix I). According to LBWD’s evaluation of the project site, wastewater generated from the proposed project would be discharge to either an existing 8-inch Vitrified Clay (VCP) sewer line in East 6th Street north of the project site, an 8-inch VCP sewer line in The Promenade North east of the southernmost parcel of the project site, or 8- inch VCP sewer lines in portions of East 5th Street, East 4th Street, and just north of the intersection of Long Beach Boulevard and East 5th Street. Therefore, development of the proposed project Downtown Plan Program EIR Addendum
The Mosaic Project 126 ESA / 201801165.12
Downtown Plan Program EIR Addendum December 2022
would be within the existing capacity of the LBWD, and impacts would be less than significant.

Thus, the proposed project would not result in a new or more severe impact related to wastewater than what was not previously considered in the Certified PEIR and LUEP Addendum.

CONCLUSION: Same Impact as “Approved Project.” The proposed project would be consistent with the analysis and conclusions presented in the Certified PEIR and LUEP Addendum; thus, impacts related to wastewater would be less than significant with implementation of the proposed project.
c) Storm Drain Resources
Refer to Section IX, Hydrology and Water Quality, of this document for discussion of the proposed project’s impacts to the City’s storm drain system.
d) Water Supply and Demand
As discussed in the Certified PEIR, buildout of the Downtown Plan would incrementally increase water supply and demand in the city. Due to the increased demand for water supply and the increase in development activity in the Downtown Plan area, the impact on water supply and demand would be considered potentially significant. However, the Certified PEIR evaluated LBWD’s capabilities and determined that the LBWD would have the resources to meet the demand of future projects in the Downtown Plan area. Therefore, development projects built within the Downtown Plan area that conform to the provisions of the Plan have been anticipated by the LBWD and impacts would be less than significant.

Water Code Section 10912(a) and (b) and SB 610 require that a Water Supply Assessment be prepared if the development is expected to demand an amount of water equivalent to or greater than the amount of water needed for 500 dwelling units. The proposed project would develop 900 dwelling units, which would exceed the 500 dwelling unit threshold under SB 610. However, in accordance with the CREED vs. City of San Diego case law, an addendum to a previous EIR that included a Water Supply Assessment can rely on the original Water Supply Assessment to satisfy the requirements of the Water Code. The Certified PEIR included a Water Availability Assessment by the LBWD, where the Certified PEIR stated that if development projects built within the Downtown Plan area conform to the provisions of the Downtown Plan and have been anticipated by the LBWD, these projects will not be required to prepare a project-specific Water Availability/Supply Assessment during the development review phase of project entitlement. A will serve letter from LBWD for the proposed project was received on October 4, 2022, which indicated that LBWD has capacity to serve the project site upon the condition of approval that the LBWD water system is able to meet the potable water demands from the final designed project through water modeling and a hydraulic study completed by LBWD (Appendix I). Therefore, a Water Supply Assessment was not required for the proposed project.

As discussed above, the 900 residential units and 38,405 square feet of commercial space proposed under the project is within the development envelope of the Certified PEIR and LUEP Addendum.

A will serve letter for the proposed project from LBWD was received and indicated that LBWD would have capacity to serve the project site upon the condition of approval that the LBWD water system is able to meet the potable water demands from the final designed project through water Downtown Plan Program EIR Addendum
The Mosaic Project 127 ESA / 201801165.12
Downtown Plan Program EIR Addendum December 2022
modeling and a hydraulic study completed by LBWD (Appendix I). Water supply would be required for both construction and operation of the proposed project. According to LBWD’s evaluation of the project site, potable water would be conveyed to the project site by either an existing 8-inch Asbestos Cement (AC) potable water line north of the project site in East 6th Street, an 8-inch AC potable water line east of the project site in Long Beach Boulevard, an 8-inch Ductile Iron (DI) potable water line south of the project site in East 4th Street, an existing 8-inch DI potable water line between the project parcels in East 5th Street, and an 8-inch DI potable water line east of the southernmost parcel of the project site in The Promenade North. Installation of new water laterals serving the new buildings’ infrastructure would be limited to minor off-site work associated with connections to the public main. Compliance with the City’s building permit process would ensure that the locations and depth of all water lines are identified prior to proposed ground disturbance activities to avoid water lines and disruption of water service.

Moreover, the proposed project would incorporate a fire sprinkler suppression system to reduce or eliminate the public hydrant demands, which would be subject to LBFD review and approval during the design and permitting of the proposed project. In addition, the project would include backflow prevention devices and separate meters pursuant to City requirements. Therefore, compliance with the California Fire Code requirements and in accordance with LBWD’s evaluation of the proposed project, impacts related to water supply and demand would be less than significant. Thus, the proposed project would not result in a new or more severe impact related to water supply and demand than what was not previously considered in the Certified PEIR and LUEP Addendum.

CONCLUSION: Same Impact as “Approved Project.” The proposed project would be consistent with the analysis and conclusions presented in the Certified PEIR and LUEP Addendum; thus, impacts related to water supply and demand would be less than significant with project implementation.
f–g) Solid Waste Disposal
As discussed in the Certified PEIR, buildout of the Downtown Plan would incrementally increase solid waste disposal treatment demand in the city. However, the city has one of the highest landfill diversion rates of any large city in the United States, with an estimated 69 percent of the City’s trash diverted from disposal through recycling, reuse, and waste reduction as of 2006 (the most recent year reported). Following collection, refuse within the city is transported directly to landfills or to landfills following combustion in the Southeast Resource Recovery Facility (SERRF), a publicly owned solid waste management facility. SERRF applies mass burn technology to reduce the volume of solid waste entering landfills by 80 percent. This technology generates electricity for operation of the SERRF and residual electricity is available for purchase by SCE for use throughout the City and State. SERRF processes an average of 1,290 tons of municipal solid waste per day with a daily capacity for 1,380 tons. It has processed over 3.5 million tons of solid waste since it first opened and has reduced the volume of solid waste entering landfills by over 4 million cubic yards.

Based on Los Angeles County Sanitation District’s (LACSD) operation of the Mesquite Regional Landfill, which is permitted for up to 20,000 tons per day for approximately 100 years, adequate landfill capacity exists to accommodate solid waste disposal needs of the Downtown Plan area.

Downtown Plan Program EIR Addendum
The Mosaic Project 128 ESA / 201801165.12
Downtown Plan Program EIR Addendum December 2022
Due to the increased demand for solid waste disposal treatment and the increase in development activity in the Downtown Plan area, the impact on solid waste disposal systems would be considered potentially significant. However, this impact would be reduced to a less-than-significant level with the implementation of Mitigation Measures Utilities-3(a) through Utilities-3(d), identified in Table 1 above.

As discussed above, the 900 residential units and 38,405 square feet of commercial space proposed under the project is within the development envelope of the Certified PEIR and LUEP Addendum.

The proposed project would generate solid waste during construction and operation. However, as indicated in the Certified PEIR and LUEP Addendum, it is expected that a large percentage of the project’s refuse would be diverted from disposal through recycling, reuse, and waste reduction, including combustion in the SERRF. The proposed project would be within the development parameters considered in the Certified PEIR and LUWP Addendum and would not allow for development at a greater density/intensity than previously considered. The proposed project would also follow all applicable solid waste policies and objectives that are required by law, statute, or regulation and would be required to implement Mitigation Measures Utilities-3(a) through Utilities-3(d) from the Certified PEIR and LUEP Addendum, which would implement recycling measures for all construction-related wastes in coordination with the City Building Official, as well as recycling bins and educational materials to encourage recycling and proper management and disposal of household hazardous waste. Thus, any potential impacts to solid waste disposal services would be reduced to a less than significant level. Therefore, implementation of the proposed project would not result in new or more severe impacts related to solid waste than what was previously considered in the Certified PEIR and LUEP Addendum.

CONCLUSION: Same Impact as “Approved Project.” The proposed project would be consistent with the analysis and conclusions presented in the Certified PEIR and LUEP Addendum; thus, the proposed project’s impacts to solid waste would be reduced to less than significant with implementation of Mitigation Measures Utilities-3(a) through Utilities-3(d).

Discussion
a) Environmental Resources
As discussed in Section IV, Biological Resources, of this document, no impacts to rare or endangered species habitats are expected. In addition, as discussed in Section V, Cultural Resources, the proposed project would not be expected to eliminate important examples of the major periods of California history or prehistory. Therefore, no impact to environmental resources would occur and further study of this issue is not warranted. b) Cumulative Impacts
The Certified PEIR and LUEP Addendum determined the Downtown Plan would cause significant and unavoidable cumulative impacts to the following resource areas: aesthetics (shade and shadow), air quality (construction and operation), cultural resources (historic), greenhouse gas emissions, noise (operational traffic), population and housing, public services (parks and recreation), transportation and traffic, and utilities and service systems (solid waste). Cumulative impacts identified for the proposed project would be similar to those identified for the Certified PEIR and LUEP Addendum for greenhouse gas emissions, public services (parks and recreation), transportation and traffic, and utilities and service systems (solid waste). The project would not have cumulative impacts greater than what was originally considered in the Certified PEIR and LUEP Addendum. Thus, considering the conclusions of this Addendum, the proposed project conforms with all of the conclusions provided in the Certified PEIR and LUEP Addendum.

Therefore, no additional cumulative impacts would occur with implementation of the proposed project than what was previously considered in the Certified PEIR and LUEP Addendum. c) Human Impacts
Generally, impacts to human beings are more specifically focused on impacts associated with air quality, hazards and hazardous materials, and noise. As discussed in the previous sections, the Downtown Plan Program EIR Addendum
The Mosaic Project 130 ESA / 201801165.12
Downtown Plan Program EIR Addendum December 2022
proposed project would not result, either directly or indirectly, in adverse hazards related to air quality, hazardous materials, or noise. Compliance with applicable rules and regulations along with implementation of appropriate mitigation measures would reduce potential impacts on human beings to a less-than-significant level. The proposed project would not result in new significant impacts or a substantial increase in severity of air quality, hazards and hazardous materials, and noise impacts than what was identified in the Certified PEIR and LUEP Addendum.

INTRODUCTION
This air quality and greenhouse gas (GHG) impact analysis has been prepared to evaluate the potential air quality and GHG emissions impacts associated with the proposed Mosaic Project (project) at 450 The Promenade North in Long Beach, California. This report provides a projectspecific air quality and GHG emissions impact analysis by examining the impacts of the proposed uses on regional air quality and nearby sensitive uses. This air quality and GHG impact analysis follows the guidelines identified by the South Coast Air Quality Management District (SCAQMD) in its California Environmental Quality Act (CEQA) Air Quality Handbook1 and associated updates.

PROJECT LOCATION AND DESCRIPTION
The 5.49-acre project site is at 450 The Promenade North in Long Beach, California. The project site is bounded by 6th Street to the north, 4th Street to the south, Long Beach Boulevard to the east, and existing residential and commercial uses and public parking structures to the west. The project location is shown on Figure 1.

The proposed project includes the demolition of 197,513 square feet of existing commercial (retail uses) that are currently on site. The project would construct 900 residential dwelling units and 38,405 square feet of commercial uses. The proposed project would consist of three residential buildings and one commercial pavilion. The buildings would have eight levels. The project would include both indoor and outdoor amenities for the future residents, including community rooms and common outdoor open space. The proposed project would have the following sustainability features: high efficiency heating, ventilation, and air conditioning (HVAC) equipment, high-efficiency gas water heater or a heat pump water heater, and solar photovoltaic (PV) with a potential battery storage. In addition, the proposed project would use low-flow plumbing fixtures. The proposed project does not include any emergency generators. The project site plan is shown on Figure 2.

Access to the project site would be provided via three garage entries along 6 th Street and Long
Beach Boulevard. The site would have a total of 1,383 parking spaces, with an additional 39 spaces for commercial parking located in existing city parking structures. The proposed project would also include 187 bicycle parking spaces. Based on the Traffic Impact Analysis (TIA) LSA prepared, once operational, the proposed project would generate approximately 3,509 net new average daily trips.2 Construction of the proposed project is anticipated to begin in the fourth quarter of 2023 and would end the fourth quarter of 2027. Based on the preliminary grading plans, in addition to the existing building demolition, 7,610 cubic yards of soil would be exported from the project site. 1 South Coast Air Quality Management District. 1993.

For the purposes of this analysis, sensitive receptors are areas of population that have an increased sensitivity to air pollution or environmental contaminants. Sensitive receptor locations include residences, schools, day care centers, hospitals, parks, and similar uses that are sensitive to air quality. Impacts on sensitive receptors are of particular concern because they are the population most vulnerable to the effects of air pollution. The project site is bounded by 6th Street to the north, 4th Street to the south, Long Beach Boulevard to the east, and existing residential and commercial uses and public parking structures to the west. Existing land uses in the project area primarily include residential and commercial uses. The closest sensitive receptors to the project site include multifamily residential uses approximately 80 feet west of the project site across The Promenade North. In addition, residential uses are located approximately 90 feet south of the project site opposite East 4th Street and approximately 130 feet east of the project site opposite Long Beach Boulevard.

BACKGROUND
This section provides background information on air pollutants and their health effects. It also provides regulatory background information, including information from the California Air Resources Board’s (CARB) Air Quality and Land Use Handbook1 (CARB Handbook); a description of the general health risks of toxics, and the significance criteria for project evaluation.

AIR POLLUTANTS AND HEALTH EFFECTS
Both State and federal governments have established health-based Ambient Air Quality Standards for six criteria air pollutants:2 carbon monoxide (CO), ozone (O3), nitrogen dioxide (NO2), sulfur dioxide (SO2), lead, and suspended particulate matter (PM). In addition, the State has set standards for sulfates, hydrogen sulfide, vinyl chloride, and visibility-reducing particles. These standards are designed to protect the health and welfare of the populace with a reasonable margin of safety.

Long-term exposure to elevated levels of criteria pollutants may result in adverse health effects.

However, emission thresholds established by an air district are used to manage total regional emissions within an air basin based on the air basin’s attainment status for criteria pollutants. These emission thresholds were established for individual projects that would contribute to regional emissions and pollutant concentrations and could adversely affect or delay the projected attainment target year for certain criteria pollutants.

Occupants of facilities such as schools, daycare centers, parks and playgrounds, hospitals, and nursing and convalescent homes are considered to be more sensitive than the general public to air pollutants because these population groups have increased susceptibility to respiratory disease.

Persons engaged in strenuous work or exercise also have increased sensitivity to poor air quality.

Residential areas are considered more sensitive to air quality conditions, compared to commercial and industrial areas, because people generally spend longer periods of time at their residences, with greater associated exposure to ambient air quality conditions. Recreational uses are also considered sensitive compared to commercial and industrial uses due to greater exposure to ambient air quality conditions associated with exercise.

Ozone
Rather than being directly emitted, O3 (smog) is formed by photochemical reactions between NOX and VOC. Ozone is a pungent, colorless gas. Elevated O3 concentrations result in reduced lung function, particularly during vigorous physical activity. This health problem is particularly acute in sensitive receptors such as the sick, elderly, and young children. O3 levels peak during the summer and early fall months.
1 California Air Resources Board. 2005. Air Quality and Land Use Handbook: A Community Health Perspective. May. 2 Criteria pollutants are defined as those pollutants for which the federal and State governments have established ambient air quality standards, or criteria, for outdoor concentrations in order to protect public health.

P:\LBL2201\Air Quality\Mosaic LB AQ-GHG Report 10032022.docx (10/03/22) 6 Carbon Monoxide
CO forms from the incomplete combustion of fossil fuels, almost entirely from automobiles. It is a colorless, odorless gas that can cause dizziness, fatigue, and impairments to central nervous system functions. CO passes through the lungs into the bloodstream, where it interferes with the transfer of oxygen to body tissues.

Particulate Matter
PM is the term used for a mixture of solid particles and liquid droplets found in the air. Coarse particles are those that are 10 microns or less in diameter, or PM10. Fine, suspended particulate matter with an aerodynamic diameter of 2.5 microns or less, or PM2.5, is not readily filtered out by the lungs. Nitrates, sulfates, dust, and combustion particulates are major components of PM10 and PM2.5. These small particles can be directly emitted into the atmosphere as byproducts of fuel combustion; through abrasion, such as tire or brake lining wear; or through fugitive dust (wind or mechanical erosion of soil). They can also be formed in the atmosphere through chemical reactions.

Particulates may transport carcinogens and other toxic compounds that adhere to the particle surfaces and can enter the human body through the lungs.

Nitrogen Dioxide
NO2 is a reddish-brown gas that is a byproduct of combustion processes. Automobiles and industrial operations are the main sources of NO2. Aside from its contribution to O3 formation, NO2 also contributes to other pollution problems, including a high concentration of fine particulate matter, poor visibility, and acid deposition. NO2 may be visible as a coloring component on high pollution days, especially in conjunction with high ozone levels. NO2 decreases lung function and may reduce resistance to infection.

Sulfur Dioxide
SO2 is a colorless, irritating gas formed primarily from incomplete combustion of fuels containing sulfur. Industrial facilities also contribute to gaseous SO2 levels in the region. SO2 irritates the respiratory tract, can injure lung tissue when combined with fine particulate matter, and reduces visibility and the level of sunlight.

Lead
Leaded gasoline (phased out in the United States beginning in 1973), paint (on older houses and cars), smelters (metal refineries), and the manufacture of lead storage batteries have been the primary sources of lead released into the atmosphere. Lead has multiple adverse neurotoxic health effects, and children are at special risk. Some lead-containing chemicals cause cancer in animals.

Lead levels in the air have decreased substantially since leaded gasoline was eliminated. Ambient lead concentrations are only monitored on an as-warranted, site-specific basis in California. On October 15, 2008, the United States Environmental Protection Agency (USEPA) strengthened the national ambient air quality standard for lead by lowering it from 1.5 to 0.15 micrograms per cubic meter (µg/m3
). The USEPA revised the monitoring requirements for lead in December 2010. These requirements focus on airports and large urban areas, resulting in an increase in 76 monitors nationally.

P:\LBL2201\Air Quality\Mosaic LB AQ-GHG Report 10032022.docx (10/03/22) 7 Volatile Organic Compounds
VOCs (also known as reactive organic gases and reactive organic compounds) are formed from the combustion of fuels and the evaporation of organic solvents. VOCs are not defined as criteria pollutants, however, because VOCs accumulate in the atmosphere more quickly during the winter, when sunlight is limited and photochemical reactions are slower, they are a prime component of the photochemical smog reaction. There are no attainment designations for VOCs.

Toxic Air Contaminants
In addition to the criteria pollutants discussed above, toxic air contaminants (TACs) are another group of pollutants of concern. TACs are injurious in small quantities and are regulated by the USEPA and the CARB. Some examples of TACs include benzene, butadiene, formaldehyde, and hydrogen sulfide. The identification, regulation, and monitoring of TACs is relatively recent compared to that for criteria pollutants.

TACs do not have ambient air quality standards, but are regulated by the USEPA, CARB, and the SCAQMD. In 1998, the CARB identified particulate matter from diesel-fueled engines as a TAC. The CARB has completed a risk management process that identified potential cancer risks for a range of activities using diesel-fueled engines.1 High-volume freeways, stationary diesel engines, and facilities attracting heavy and constant diesel vehicle traffic (e.g., distribution centers and truck stops) were identified as posing the highest risk to adjacent receptors. Other facilities associated with increased risk include warehouse distribution centers, large retail or industrial facilities, high-volume transit centers, and schools with a high volume of bus traffic. Health risks from TACs are a function of both concentration and duration of exposure.

Unlike TACs emitted from industrial and other stationary sources noted above, most diesel particulate matter is emitted from mobile sources—primarily “off-road” sources such as construction and mining equipment, agricultural equipment, and truck-mounted refrigeration units, as well as “on-road” sources such as trucks and buses traveling on freeways and local roadways.

Although not specifically monitored, recent studies indicate that exposure to diesel particulate matter may contribute significantly to a cancer risk (a risk of approximately 500 to 700 in 1,000,000) that is greater than all other measured TACs combined.2 The technology for reducing diesel particulate matter emissions from heavy-duty trucks is well established, and both State and federal agencies are moving aggressively to regulate engines and emission control systems to reduce and remediate diesel emissions. The CARB anticipates that by 2020, average statewide diesel particulate matter concentrations will decrease by 85 percent from levels in 2000 with full implementation of the CARB’s Diesel Risk Reduction Plan,3 meaning that the statewide health risk from diesel 1 California Air Resources Board. 2000.

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.
b 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.

Contact USEPA for further clarification and current national policies. c 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.
d Any equivalent measurement method which can be shown to the satisfaction of the CARB to give equivalent results at or near the level of the air quality standard may be used.
e National Primary Standards: The levels of air quality necessary, with an adequate margin of safety to protect the public health. f National Secondary Standards: The levels of air quality necessary to protect the public welfare from any known or anticipated adverse effects of a pollutant.
g Reference method as described by the USEPA. An “equivalent method” of measurement may be used but must have a “consistent relationship to the reference method” and must be approved by the USEPA. h On October 1, 2015, the national 8-hour ozone primary and secondary standards were lowered from 0.075 to 0.070 ppm. i On December 14, 2012, the national annual PM2.5 primary standard was lowered from 15 μg/m3 to 12.0 μg/m3 . The existing national
24- hour PM2.5 standards (primary and secondary) were retained at 35 μg/m3 , as was the annual secondary standard of 15 μg/m3. The existing 24-hour PM10 standards (primary and secondary) of 150 μg/m3 also were retained. The form of the annual primary and secondary standards is the annual mean, averaged over 3 years. j 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. k 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 parts per billion (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.
l The 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.
m 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.
n In 1989, the 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.

GREENHOUSE GASES AND GLOBAL CLIMATE CHANGE
Global climate change is the observed increase in the average temperature of the Earth’s atmosphere and oceans in recent decades. The Earth’s average near-surface atmospheric temperature rose 0.6 ± 0.2° Celsius or 1.1 ± 0.4° Fahrenheit (°F) in the 20th century. The prevailing scientific opinion on climate change is that most of the warming observed over the last 50 years is attributable to human activities. The increased amounts of carbon dioxide (CO2) and other GHGs are the primary causes of the human-induced component of warming. GHGs are released by the burning of fossil fuels, land clearing, agriculture, and other activities, and lead to an increase in the greenhouse effect.1
GHGs are present in the atmosphere naturally, are released by natural sources, or are formed from secondary reactions taking place in the atmosphere. The gases that are widely seen as the principal contributors to human-induced global climate change are:
• CO2
• Methane (CH4)
• Nitrous oxide (N2O)
• Hydrofluorocarbons (HFC)
• Perfluorocarbons (PFC)
• Sulfur hexafluoride (SF6)
• Nitrogen trifluoride (NF3)
Over the last 200 years, humans have caused substantial quantities of GHGs to be released into the atmosphere. These extra emissions are increasing GHG concentrations in the atmosphere, and enhancing the natural greenhouse effect, which is believed to be causing global warming. While manmade GHGs include naturally occurring GHGs such as CO2, CH4, and N2O, some gases, like HFCs, PFCs, and SF6 are completely new to the atmosphere.

Certain gases, such as water vapor, are short-lived in the atmosphere. Others remain in the atmosphere for significant periods of time, contributing to climate change in the long term. Water vapor is excluded from the list of GHGs above because it is short-lived in the atmosphere and its atmospheric concentrations are largely determined by natural processes, such as oceanic evaporation. For the purposes of this air quality analysis, the term “GHGs” will refer collectively to the six gases listed above only.

These gases vary considerably in terms of global warming potential (GWP), which is a concept developed to compare the ability of each GHG to trap heat in the atmosphere relative to another gas. The global warming potential is based on several factors, including the relative effectiveness of 1 The temperature on Earth is regulated by a system commonly known as the “greenhouse effect.” Just as the glass in a greenhouse lets heat from sunlight in and reduces the heat escaping, greenhouse gases like carbon dioxide, methane, and nitrous oxide in the atmosphere keep the Earth at a relatively even temperature. Without the greenhouse effect, the Earth would be a frozen globe; thus, although an excess of greenhouse gas results in global warming, the naturally occurring greenhouse effect is necessary to keep our planet at a comfortable temperature.

The GWP of each gas is measured relative to CO2, the most abundant GHG; the definition of GWP for a particular GHG is the ratio of heat trapped by one unit mass of the GHG to the ratio of heat trapped by one unit mass of CO2 over a specified time period. GHG emissions are typically measured in terms of pounds or tons of “CO2 equivalents” (CO2e). Table C shows the GWP for each type of GHG. For example, SF6 is 22,800 times more potent at contributing to global warming than carbon dioxide.

The following discussion summarizes the characteristics of the six GHGs and black carbon.

Carbon Dioxide
In the atmosphere, carbon generally exists in its oxidized form, as CO2. Natural sources of CO2 include the respiration (breathing) of humans, animals and plants, volcanic out gassing, decomposition of organic matter and evaporation from the oceans. Human caused sources of CO2 include the combustion of fossil fuels and wood, waste incineration, mineral production, and deforestation. Natural sources release approximately 150 billion tons of CO2 each year, far outweighing the 7 billion tons of man-made emissions of CO2 each year. Nevertheless, natural removal processes, such as photosynthesis by land- and ocean-dwelling plant species, cannot keep pace with this extra input of man-made CO2, and consequently, the gas is building up in the atmosphere. In 2019, total annual CO2 accounted for approximately 83 percent of California's overall GHG emissions.1 Transportation is the single largest source of CO2 in California, which is primarily comprised of on-road travel. Electricity production, industrial and residential sources also make important contributions to CO2 emissions in California.

Methane
CH4 is produced when organic matter decomposes in environments lacking sufficient oxygen.

Natural sources include wetlands, termites, and oceans. Decomposition in landfills accounts for the 1 California Air Resources Board. 2021a. GHGs Descriptions & Sources in California. Website: ww2.arb.ca. gov/ghg-descriptions-sources (accessed July 2022).

P:\LBL2201\Air Quality\Mosaic LB AQ-GHG Report 10032022.docx (10/03/22) 13 majority of human-generated CH4 emissions in California and in the United States as a whole.

Agricultural processes such as intestinal fermentation, manure management, and rice cultivation are also significant sources of CH4 in California. Total annual emissions of CH4 accounted for approximately 9 percent of GHG emissions in California. 1 Nitrous Oxide
N2O is produced naturally by a wide variety of biological sources, particularly microbial action in soils and water. Tropical soils and oceans account for the majority of natural source emissions. Nitrous oxide is a product of the reaction between nitrogen and oxygen during fuel combustion. Both mobile and stationary combustion emit N2O, and the quantity emitted varies according to the type of fuel, technology, and pollution control device used, as well as maintenance and operating practices. Agricultural soil management and fossil fuel combustion are the primary sources of human-generated N2O emissions in California. Nitrous oxide emissions accounted for approximately 3 percent of GHG emissions in California in 2019.
2 Hydrofluorocarbons, Perfluorocarbons, Sulfur Hexafluoride, and Nitrogen Trifluoride HFCs are primarily used as substitutes for ozone-depleting substances regulated under the Montreal Protocol.3 PFCs and SF6 are emitted from various industrial processes, including aluminum smelting, semiconductor manufacturing, electric power transmission and distribution, and magnesium casting. Semiconductor manufacturing also emits a small amount of NF3 which was added to the inventory as required by Senate Bill (SB) 104 passed in 2009, because it is a potent GHG.4 There is no aluminum or magnesium production in California; however, the rapid growth in the semiconductor industry leads to greater use of PFCs. HFCs, PFCs, SF6, and NF3 accounted for about 5 percent of GHG emissions in California in 2019.
5 Black Carbon
Black carbon is the most strongly light-absorbing component of PM formed by burning fossil fuels such as coal, diesel, and biomass. Black carbon is emitted directly into the atmosphere in the form of PM2.5 and is the most effective form of PM, by mass, at absorbing solar energy. Per unit of mass in the atmosphere, black carbon can absorb 1 million times more energy than CO2. 6 Black carbon
contributes to climate change both directly, such as absorbing sunlight, and indirectly, such as 1 California Air Resources Board (CARB). 2021a. GHGs Descriptions & Sources in California. Website:

Most United States emissions of black carbon come from mobile sources (52 percent), particularly from diesel-fueled vehicles. The other major source of black carbon is open biomass burning, including wildfires, although residential heating and industry also contribute. The CARB estimates that the annual black carbon emissions in California have decreased approximately 70 percent between 1990 and 2010 and are expected to continue to decline significantly due to controls on mobile diesel emissions.

Effects of Global Climate Change
Effects from global climate change may arise from temperature increases, climate-sensitive diseases, extreme weather events, and air quality. There may be direct temperature effects through increases in average temperature leading to more extreme heat waves and less extreme cold spells.

Those living in warmer climates are likely to experience more stress and heat-related problems.

Heat-related problems include heat rash and heat stroke. In addition, climate-sensitive diseases may increase, such as those spread by mosquitoes and other disease-carrying insects. Such diseases include malaria, dengue fever, yellow fever, and encephalitis. Extreme events such as flooding and hurricanes can displace people and agriculture. Global climate change may also contribute to air quality problems from increased frequency of smog and particulate air pollution.1 Additionally, according to the 2006 California Climate Action Team (CAT) Report,2 the following applicable climate change effects, which are based on trends established by the United Nations Intergovernmental Panel on Climate Change (IPCC), can be expected in California over the course of the next century.
• The loss of sea ice and mountain snowpack, resulting in higher sea levels and higher sea surface evaporation rates with a corresponding increase in tropospheric water vapor due to the atmosphere’s ability to hold more water vapor at higher temperatures.3 • Rise in global average sea level, primarily due to thermal expansion and melting of glaciers and ice caps in the Greenland and Antarctic ice sheets.4

REGULATORY SETTING
This section provides regulatory background information for air quality and GHG.

AIR QUALITY REGULATORY SETTING
The USEPA and the CARB regulate direct emissions from motor vehicles. The SCAQMD is the regional agency primarily responsible for regulating air pollution emissions from stationary sources (e.g., factories) and indirect sources (e.g., traffic associated with new development), as well as monitoring ambient pollutant concentrations.

Federal Clean Air Act
The 1970 federal Clean Air Act authorized the establishment of national health-based air quality standards and also set deadlines for their attainment. The federal Clean Air Act Amendments of 1990 changed deadlines for attaining national standards as well as the remedial actions required of areas of the nation that exceed the standards. Under the Clean Air Act, State and local agencies in areas that exceed the national standards are required to develop State Implementation Plans to demonstrate how they will achieve the national standards by specified dates.

California Clean Air Act
In 1988, the California Clean Air Act (CCAA) required that all air districts in the State endeavor to achieve and maintain California ambient air quality standards (CAAQS) for CO2, O3, SO2, and NO2 by the earliest practical date. The California Clean Air Act provides districts with authority to regulate indirect sources and mandates that air quality districts focus particular attention on reducing emissions from transportation and area-wide emission sources. Each nonattainment district is required to adopt a plan to achieve a 5 percent annual reduction, averaged over consecutive 3-year periods, in district-wide emissions of each nonattainment pollutant or its precursors. A Clean Air Plan shows how a district would reduce emissions to achieve air quality standards. Generally, the State standards for these pollutants are more stringent than the national standards.

The CARB is the State’s “clean air agency.” The CARB’s goals are to attain and maintain healthy air quality, protect the public from exposure to toxic air contaminants, and oversee compliance with air pollution rules and regulations.

Assembly Bill 2588 Air Toxics ‘Hot Spots’ Information and Assessment Act Under Assembly Bill (AB) 2588, stationary sources of air pollutants are required to report the types and quantities of certain substances their facilities routinely released into the air. The goals of the Air Toxics “Hot Spots” Act are to collect emission data, identify facilities having localized impacts, determine health risks, and notify nearby residents of significant risks.

P:\LBL2201\Air Quality\Mosaic LB AQ-GHG Report 10032022.docx (10/03/22) 18 The California Air Resources Board Handbook
The CARB has developed an Air Quality and Land Use Handbook1 intended to serve as a general reference guide for evaluating and reducing air pollution impacts associated with new projects that go through the land use decision-making process. According to the CARB Handbook, recent air pollution studies have shown an association between respiratory and other non-cancer health effects and proximity to high traffic roadways. Other studies have shown that diesel exhaust and other cancer-causing chemicals emitted from cars and trucks are responsible for much of the overall cancer risk from airborne toxics in California. The CARB Handbook recommends that county and city planning agencies strongly consider proximity to these sources when finding new locations for “sensitive” land uses such as homes, medical facilities, daycare centers, schools, and playgrounds.

Land use designations with air pollution sources of concern include freeways, rail yards, ports, refineries, distribution centers, chrome plating facilities, dry cleaners, and large gasoline service stations. Key recommendations in the CARB Handbook include taking steps to avoid siting new, sensitive land uses:
• Within 500 feet of a freeway, urban roads with 100,000 vehicles/day or rural roads with 50,000 vehicles/day.
• Within 1,000 feet of a major service and maintenance rail yard. • Immediately downwind of ports (in the most heavily impacted zones) and petroleum refineries. • Within 300 feet of any dry cleaning operation (for operations with two or more machines, provide 500 feet).
• Within 300 feet of a large gas station (defined as a facility with a throughput of 3.6 million gallons per year or greater).

The CARB Handbook specifically states that its recommendations are advisory and acknowledges land use agencies have to balance other considerations, including housing and transportation needs, economic development priorities, and other quality of life issues.

The recommendations are generalized and do not consider site-specific meteorology, freeway truck percentages, or other factors that influence risk for a particular project site. The purpose of this guidance is to further examine project sites for actual health risk associated with the location of new sensitive land uses.

The SCAQMD is the agency principally responsible for comprehensive air pollution control in the Basin and is tasked with implementing certain programs and regulations required by the CAA and the CCAA. The SCAQMD prepares plans to attain CAAQS and national ambient air quality standards (NAAQS). SCAQMD is directly responsible for reducing emissions from stationary (area and point) sources. The SCAQMD develops rules and regulations, establishes permitting requirements, inspects emissions sources, and enforces such measures though educational programs or fines, when necessary.

The proposed project could be subject to the following SCAQMD rules and regulations. • Regulation IV - Prohibitions: This regulation sets forth the restrictions for visible emissions, odor nuisance, fugitive dust, various air pollutant emissions, fuel contaminants, start-up/shut-down exemptions, and breakdown events.
○ Rule 402 - Nuisance: This rule restricts the discharge of any contaminant in quantities that cause or have a natural ability to cause injury, damage, nuisance, or annoyance to businesses, property, or the public.
○ Rule 403 - Fugitive Dust: This rule requires the prevention, reduction, or mitigation of fugitive dust emissions from a project site. Rule 403 restricts visible fugitive dust to a project property line, restricts the net PM10 emissions to less than 50 µg/m3 and restricts the tracking out of bulk materials onto public roads. Additionally, Rule 403 requires an applicant to utilize one or more of the best available control measures (identified in the tables within the rule). Control measures may include adding freeboard to haul vehicles, covering loose material on haul vehicles, watering, using chemical stabilizers, and/or ceasing all activities.

Finally, Rule 403 requires that a contingency plan be prepared if so determined by the USEPA. In addition, SCAQMD Rule 403(e), Additional Requirements for Large Operations, includes requirements to provide Large Operation Notification Form 403 N, appropriate signage, additional dust control measures, and employment of a dust control supervisor that has successfully completed the Dust Control training class in the South Coast Air Basin. • Regulation XI - Source Specific Standards: Regulation XI sets emissions standards for different sources.
○ Rule 1113 - Architectural Coatings: This rule limits the amount of VOCs from architectural coatings and solvents, which lowers the emissions of odorous compounds.

The SCAQMD is responsible for demonstrating regional compliance with ambient air quality standards but has limited indirect involvement in reducing emissions from fugitive, mobile, and natural sources. To that end, the SCAQMD works cooperatively with the CARB, the Southern California Association of Governments (SCAG), county transportation commissions, local governments, and other federal and State government agencies. It has responded to this requirement by preparing a series of Air Quality Management Plans (AQMPs) to meet CAAQS and NAAQS. SCAQMD and the SCAG are responsible for formulating and implementing the AQMP for the Basin. The main purpose of an AQMP is to bring the area into compliance with federal and State air

SCAQMD approved the 2016 AQMP on March 3, 2017, and submitted the plan to CARB on March 10, 2017. Key elements of the 2016 AQMP include:
• Calculating and taking credit for co-benefits from other planning efforts (e.g., climate, energy, and transportation)
• A strategy with fair-share emission reductions at the federal, State, and local levels • Investment in strategies and technologies meeting multiple air quality objectives • Seeking new partnerships and significant funding for incentives to accelerate deployment of zero-emission and near-zero emission technologies
• Enhanced socioeconomic assessment, including an expanded environmental justice analysis • Attainment of the 24-hour PM2.5 standard in 2019 with no additional measures • Attainment of the annual PM2.5 standard by 2025 with implementation of a portion of the O3 strategy
• Attainment of the 1-hour O3 standard by 2022 with no reliance on “black box” future technology (Clean Air Act Section 182(e)(5) measures)
The SCAQMD is currently preparing the 2022 AQMP, which will address the requirements for meeting the 2015 O3 standard. A Control Measures Workshop was held on November 10, 2021, to provide an overview of the control measures and strategies that are being developed/considered for the 2022 AQMP. The control measures include updated 2016 AQMP control measures and new control measures related to area, mobile, and stationary sources.

Southern California Association of Governments
SCAG is a council of governments for Los Angeles, Orange, Riverside, San Bernardino, Imperial, and Ventura counties. It is a regional planning agency and serves as a forum for regional issues relating to transportation, the economy and community development, and the environment. SCAG is the federally designated Metropolitan Planning Organization (MPO) for the majority of the southern California region and is the largest MPO in the nation. With regard to air quality planning, SCAG prepares the Regional Transportation Plan (RTP) and Regional Transportation Improvement Program (RTIP), which address regional development and growth forecasts and form the basis for the land use and transportation control portions of the AQMP and are utilized in the preparation of the air quality forecasts and consistency analysis included in the AQMP.

The RCP is a framework for decision‐making for local governments, assisting them in meeting federal and State mandates for growth management, mobility, and environmental standards, while maintaining consistency with regional goals regarding growth and changes. Policies within the RCP include consideration of air quality, land use, transportation, and economic relationships by all levels of government.

SCAG adopted the 2020–2045 Regional Transportation Plan/Sustainable Communities Strategy (Connect SoCal) on September 3, 2020. Connect SoCal is a long-range visioning plan that balances future mobility and housing needs with economic, environmental, and public health goals. Connect SoCal is an important planning document for the region, allowing project sponsors to qualify for federal funding and taking into account operations and maintenance costs to ensure reliability, longevity, and cost effectiveness. The forecasted development pattern, when integrated with the financially constrained transportation investments identified in Connect SoCal, would reach the regional target of reducing GHG emissions from automobiles and light-duty trucks by 19 percent by 2035 (compared to 2005 levels).

The project site is with the City of Long Beach Downtown Plan area. The City of Long Beach Downtown Plan Program Environmental Impact Report (Downtown Plan PEIR) identified the following mitigation measures that would apply to the proposed project and that would help to reduce and avoid potential impacts related to air quality:
• Mitigation Measure AQ-1(a): To reduce short-term construction emissions, the City shall require that all construction projects that would require use of heavy-duty (50 horsepower [hp] or more), off-road vehicles to be used during construction shall require their contractors to implement the Enhanced Exhaust Control Practices (listed below) or whatever mitigation measures are recommended by SCAQMD at the time individual portions of the site undergo construction, including those specified in the mitigation recommendations in the SCAQMD CEQA Handbook or SCAQMD’s Mitigation Measures and Control Efficiencies recommendations located at the following url: http://www.aqmd.gov/ceqa/handbook/mitigation/MM_intro.html.

Enhanced Exhaust Control Practices
○ The project applicant shall provide a plan for approval by the City, demonstrating that the heavy-duty (50 hp or more) offroad vehicles to be used in the construction project, including owned, leased, and subcontractor vehicles, will achieve a project-wide fleet-average 20 percent NOx reduction, 20 percent VOC reduction, and 45 percent particulate reduction compared to the 2011 CARB fleet average, as contained in the URBEMIS output sheets in Appendix C [of the Downtown Plan PEIR]. Acceptable options for reducing emissions may include use of late-model engines, low-emission diesel products, alternative fuels, engine retrofit technology, after-treatment products, and/or other options as they become available. SCAQMD, which is the resource agency for air quality in the project area, can be used in an advisory role to demonstrate fleet-wide reductions. SCAQMD’s mitigation measures for off-road engines can be used to identify an equipment fleet that achieves this reduction (SCAQMD 2007b).
○ The project applicant shall submit to the City a comprehensive inventory of all off-road construction equipment, equal to or greater than 50 hp, that would be used an aggregate of 40 or more hours during any portion of the construction project. The inventory shall include the hp rating, engine production year, and projected hours of use for each piece of equipment. The inventory shall be updated and submitted monthly throughout the duration of the project, except that an inventory shall not be required for any 30-day period in which no construction activity occurs. At least 48 hours prior to the use of heavy-duty off-road equipment, the project representative shall provide the City with the anticipated construction timeline including start date and name and phone number of the project manager and onsite foreman. A visual survey of all in-operation equipment shall be made at least weekly, and a monthly summary of the visual survey results shall be submitted throughout the duration of the project, except that the monthly summary shall not be required for any 30-day period in which no construction activity occurs. The monthly summary shall include the quantity and type of vehicles surveyed and the dates of each

○ If, at the time of construction, SCAQMD, CARB, or the EPA has adopted a regulation or new guidance applicable to construction emissions, compliance with the regulation or new guidance may completely or partially replace this mitigation if it is equal to or more effective than the mitigation contained herein, and if the City so permits. Such a determination must be supported by a project-level analysis and be approved by the City. • Mitigation Measure AQ-1(b): Prior to construction of each development phase of onsite land uses that are proposed within 1,500 feet of sensitive receptors, each project applicant shall perform a project-level CEQA analysis that includes a detailed LST analysis of constructiongenerated emissions of NO2, CO, PM10, and PM2.5 to assess the impact at nearby sensitive receptors. The LST analysis shall be performed in accordance with applicable SCAQMD guidance that is in place at the time the analysis is performed. The project-level analysis shall incorporate detailed parameters of the construction equipment and activities, including the year during which construction would be performed, as well as the proximity of potentially affected receptors, including receptors proposed by the project that exist at the time the construction activity would occur.
• Mitigation Measure AQ-1(c): Prior to issuance of a grading permit, the project plans shall include the following provisions to reduce construction-related air quality impacts:
○ Provide temporary traffic controls such as a flag person, during all phases of construction to maintain smooth traffic flow;
○ Provide dedicated turn lanes for movement of construction trucks and equipment on- and off-site;
○ Reroute construction trucks away from congested streets or sensitive receptor areas; ○ Appoint a construction relations officer to act as a community liaison concerning onsite construction activity including resolution of issues related to PM10 generation; ○ Improve traffic flow by signal synchronization, and ensure that all vehicles and equipment will be properly tuned and maintained according to manufacturers’ specifications; ○ Use coatings and solvents with a VOC content lower than that required under AQMD Rule 1113;
○ Construct or build with materials that do not require painting; ○ Require the use of pre-painted construction materials if available; ○ Require the use of 2010 and newer diesel haul trucks (e.g., material delivery trucks and soil import/export);

Drycleaning operations that use perchloroethylene shall not be located within 300 feet of any sensitive receptor. A setback of 500 feet shall be provided for operations with two or more machines. • Mitigation Measure AQ-6: The following mitigation measures shall be implemented to control exposure of sensitive receptors to operational odorous emissions. The City shall ensure that all project applicant(s) implement the following measures:
○ The City shall consider the odor-producing potential of land uses when reviewing future development proposals and when the exact type of facility that would occupy areas zoned for commercial, industrial, or mixed-use land uses is determined. Facilities that have the potential to emit objectionable odors shall be located as far away as feasible from existing and proposed sensitive receptors.
○ Before the approval of building permits, odor-control devices shall be identified to mitigate the exposure of receptors to objectionable odors if a potential odor producing source is to occupy an area zoned for commercial land use. The identified odor-control devices shall be installed before the issuance of certificates of occupancy for the potentially odor producing use. The odor-producing potential of a source and control devices shall be determined in coordination with SCAQMD and based on the number of complaints associated with existing sources of the same nature.
○ Truck loading docks and delivery areas shall be located as far away as feasible from existing and proposed sensitive receptors.
○ Signs shall be posted at all loading docks and truck loading areas to indicate that dieselpowered delivery trucks must be shut off when not in use for longer than 5 minutes on the premises in order to reduce idling emissions. This measure is consistent with the ATCM to Limit Diesel-Fueled Commercial Motor Vehicle Idling, which was approved by California’s Office of Administrative Law in January 2005. (This measure is also required by Mitigation Measure AQ-4 to limit TAC emissions.)

GREENHOUSE GAS REGULATORY SETTING
This section describes regulations related to global climate change at the federal, State, and local level.

Federal Regulations
The United States has historically had a voluntary approach to reducing GHG emissions. However, on April 2, 2007, the United States Supreme Court ruled that the USEPA has the authority to regulate CO2 emissions under the federal Clean Air Act. While there currently are no adopted federal regulations for the control or reduction of GHG emissions, the USEPA commenced several actions in 2009 to implement a regulatory approach to global climate change.

This includes the 2009 USEPA final rule for mandatory reporting of GHGs from large GHG emission sources in the United States. Additionally, the USEPA Administrator signed an endangerment finding action in 2009 under the Clean Air Act, finding that six GHGs (CO2, CH4, N2O, HFCs, PFCs, SF6) constitute a threat to public health and welfare, and that the combined emissions from motor vehicles cause and contribute to global climate change, leading to national GHG emission standards.

In October 2012, the USEPA and the National Highway Traffic Safety Administration (NHTSA), on behalf of the United States Department of Transportation, issued final rules to further reduce GHG emissions and improve corporate average fuel economy (CAFE) standards for light-duty vehicles for model years 2017 and beyond (77 Federal Register 62624). The NHTSA’s CAFE standards have been enacted under the Energy Policy and Conservation Act since 1978. This national program requires automobile manufacturers to build a single light-duty national fleet that meets all requirements under both federal programs and the standards of California and other states. This program would increase fuel economy to the equivalent of 54.5 miles per gallon, limiting vehicle emissions to 163 grams of CO2 per mile for the fleet of cars and light-duty trucks by model year 2025 (77 Federal Register 62630).

On March 21, 2020, the USEPA and the NHTSA finalized the Safer Affordable Fuel-Efficient (SAFE) Vehicles Rule for Model Years 2021–2026 Passenger Cars and Light Trucks (SAFE Vehicles Rule). The SAFE Vehicles Rule amends certain existing CAFE and tailpipe CO2 emissions standards for passenger cars and light trucks and establish new standards, all covering model years 2021 through 2026. More specifically, NHTSA set new CAFE standards for model years 2022 through 2026 and amended its 2021 model year CAFE standards, and the USEPA amended its CO2 emissions standards for model years 2021 and later. On May 12, 2021, the NHTSA published a notice of proposed rulemaking in the Federal Register, proposing to repeal key portions of the SAFE Vehicles Rule that would have reduced CAFE standards. The final rule repealing portions of the SAFE Vehicles Rule was published on December 29, 2021. The repeal will allow California to set its own GHG standards if it chooses, even if the emissions standards conflict with CAFE standards enacted by the United States Department of Transportation.

P:\LBL2201\Air Quality\Mosaic LB AQ-GHG Report 10032022.docx (10/03/22) 29 State Regulations
The CARB is the lead agency for implementing climate change regulations in the State. Since its formation, the CARB has worked with the public, the business sector, and local governments to find solutions to California’s air pollution problems. Key efforts by the State are described below.

Assembly Bill 1493 (2002)
In a response to the transportation sector’s significant contribution to California’s CO2 emissions, AB 1493 was enacted on July 22, 2002. AB 1493 requires the CARB to set GHG emission standards for passenger vehicles and light duty trucks (and other vehicles whose primary use is noncommercial personal transportation in the State) manufactured in 2009 and all subsequent model years. These standards (starting in model years 2009 to 2016) were approved by the CARB in 2004, but the needed waiver of CAA Preemption was not granted by the USEPA until June 30, 2009. The CARB responded by amending its original regulation, now referred to as Low Emission Vehicle III, to take effect for model years starting in 2017 to 2025. The Trump administration revoked California’s waiver in 2019, but the Biden administration restored California’s waiver in 2021 Executive Order S-3-05 (2005)
Governor Arnold Schwarzenegger signed Executive Order S-3-05 on June 1, 2005, which proclaimed that California is vulnerable to the impacts of climate change. To combat those concerns, the executive order established California’s GHG emissions reduction targets, which established the following goals.
• GHG emissions should be reduced to 2000 levels by 2010. • GHG emissions should be reduced to 1990 levels by 2020. • GHG emissions should be reduced to 80 percent below 1990 levels by 2050.

The Secretary of the California Environmental Protection Agency (CalEPA) is required to coordinate efforts of various State agencies in order to collectively and efficiently reduce GHGs. A biannual progress report must be submitted to the Governor and State Legislature disclosing the progress made toward greenhouse emission reduction targets. In addition, another biannual report must be submitted illustrating the impacts of global warming on California’s water supply, public health, agriculture, the coastline, and forestry, and report possible mitigation and adaptation plans to address these impacts.

The Secretary of CalEPA leads this CAT made up of representatives from State agencies as well as numerous other boards and departments. The CAT members work to coordinate statewide efforts to implement global warming emission reduction programs and the State’s Climate Adaptation Strategy. The CAT is also responsible for reporting on the progress made toward meeting the statewide GHG targets that were established in the executive order and further defined under AB 32, the “Global Warming Solutions Act of 2006.” The first CAT Report to the Governor and the Legislature was released in March 2006, which laid out 46 specific emission reduction strategies for reducing GHG emissions and reaching the targets established in the Executive Order. The most recent report was released in December 2020.

P:\LBL2201\Air Quality\Mosaic LB AQ-GHG Report 10032022.docx (10/03/22) 30 Assembly Bill 32 (2006), California Global Warming Solutions Act California’s major initiative for reducing GHG emissions is AB 32, passed by the State Legislature on August 31, 2006. This effort aims at reducing GHG emissions to 1990 levels by 2020. The CARB has established the level of GHG emissions in 1990 at 427 million metric tons (MMT) of CO2e. The emissions target of 427 MMT requires the reduction of 169 MMT from the State’s projected business-as-usual 2020 emissions of 596 MMT. AB 32 requires the CARB to prepare a Scoping Plan that outlines the main State strategies for meeting the 2020 deadline and to reduce GHGs that contribute to global climate change. The Scoping Plan was approved by the CARB on December 11, 2008, and contains the main strategies California will implement to achieve the reduction of approximately 169 MMT of CO2e, or approximately 30 percent, from the State’s projected 2020 emissions level of 596 MMT of CO2e under a business-as-usual scenario (this is a reduction of 42 MMT CO2e, or almost 10 percent from 2002–2004 average emissions). The Scoping Plan also includes CARB-recommended GHG reductions for each emissions sector of the State’s GHG inventory. The Scoping Plan calls for the largest reductions in GHG emissions to be achieved by implementing the following measures and standards.
• Improved emissions standards for light-duty vehicles (estimated reductions of 31.7 MMT CO2e) • The Low-Carbon Fuel Standard (15 MMT CO2e)
• Energy efficiency measures in buildings and appliances and the widespread development of combined heat and power systems (26.3 MMT CO2e)
• A renewable portfolio standard for electricity production (21.3 MMT CO2e) The Scoping Plan identifies 18 emission reduction measures that address cap-and-trade programs, vehicle gas standards, energy efficiency, low carbon fuel standards, renewable energy, regional transportation-related GHG targets, vehicle efficiency measures, goods movement, solar roof programs, industrial emissions, high-speed rail, green building strategies, recycling, sustainable forests, water, and air. The measures would result in a total reduction of 174 MMT CO2e by 2020.

On August 24, 2011, the CARB unanimously approved both the new supplemental assessment and reapproved its Scoping Plan, which provides the overall roadmap and rule measures to carry out AB 32. The CARB also approved a more robust CEQA equivalent document supporting the supplemental analysis of the cap-and-trade program. The cap-and-trade took effect on January 1, 2012, with an enforceable compliance obligation that began January 1, 2013.

CARB has not yet determined what amount of GHG reductions it recommends from local government operations and local land use decisions; however, the Scoping Plan states that land use planning and urban growth decisions will play an important role in the State’s GHG reductions because local governments have primary authority to plan, zone, approve, and permit how land is developed to accommodate population growth and the changing needs of their jurisdictions (meanwhile, CARB is also developing an additional protocol for community emissions). CARB further acknowledges that decisions on how land is used will have large impacts on the GHG emissions that will result from the transportation, housing, industry, forestry, water, agriculture, electricity, and

The Scoping Plan states that the ultimate GHG reduction assignment to local government operations is to be determined. With regard to land use planning, the Scoping Plan expects an approximately 5.0 MMT CO2e reduction due to implementation of SB 375.

In addition to reducing GHG emissions to 1990 levels by 2020, AB 32 directed the CARB and the CAT to identify a list of “discrete early action GHG reduction measures” that could be adopted and made enforceable by January 1, 2010. On January 18, 2007, Governor Schwarzenegger signed Executive Order S-1-07, further solidifying California’s dedication to reducing GHGs by setting a new Low Carbon Fuel Standard. The Executive Order sets a target to reduce the carbon intensity of California transportation fuels by at least 10 percent by 2020 and directs the CARB to consider the Low Carbon Fuel Standard as a discrete early action measure. In 2011, United States District Court Judge Lawrence O’Neil issued an injunction preventing implementation of the Low Carbon Fuel Standard, ruling that it is unconstitutional. In 2012, the Ninth Circuit Court of Appeal stayed the District Court’s injunction, allowing implementation of the Low Carbon Fuel Standard. The Ninth Circuit decided to uphold the Low Carbon Fuel Standard.

In June 2007, the CARB approved a list of 37 early action measures, including three discrete early action measures (Low Carbon Fuel Standard, Restrictions on GWP Refrigerants, and Landfill CH4 Capture).1 Discrete early action measures are measures that were required to be adopted as regulations and made effective no later than January 1, 2010, the date established by Health and Safety Code Section 38560.5. The CARB adopted additional early action measures in October 2007 that tripled the number of discrete early action measures. These measures relate to truck efficiency, port electrification, reduction of PFCs from the semiconductor industry, reduction of propellants in consumer products, proper tire inflation, and SF6 reductions from the non-electricity sector. The combination of early action measures is estimated to reduce statewide GHG emissions by nearly 16 MMT.2

The First Update identifies opportunities to leverage existing and new funds to further drive GHG emission reductions through strategic planning and targeted low carbon investments. The First Update defines CARB climate change priorities until 2020, and also sets the groundwork to reach long-term goals set forth in Executive Orders S-3-05 and B-16-2012. The Update highlights California’s progress toward meeting the “near-term” 2020 GHG emission reduction goals as defined in the initial Scoping Plan. It also evaluates how to align the State’s “longer-term” GHG reduction strategies with other State policy priorities for water, waste, natural resources, clean energy, transportation, and land use. CARB released a second update to the Scoping Plan, the 2017 Scoping Plan, 1 to reflect the 2030
target set by Executive Order B-30-15 and codified by SB 32.

The Draft 2022 Scoping Plan Update2 assesses progress toward the statutory 2030 target, while laying out a path to achieving carbon neutrality no later than 2045. The 2022 Scoping Plan Update focuses on outcomes needed to achieve carbon neutrality by assessing paths for clean technology, energy deployment, natural and working lands, and others, and is designed to meet the State’s longterm climate objectives and support a range of economic, environmental, energy security, environmental justice, and public health priorities.

Senate Bill 97 (2007)
SB 97, signed by the Governor in August 2007 (Chapter 185, Statutes of 2007; Public Resources Code, Sections 21083.05 and 21097), acknowledges climate change is a prominent environmental issue that requires analysis under CEQA. This bill directed the Governor’s Office of Planning and Research to prepare, develop, and transmit to the California Resources Agency guidelines for mitigating GHG emissions or the effects of GHG emissions, as required by CEQA.

The California Natural Resources Agency adopted the amendments to the State CEQA Guidelines in November 2018, which went into effect in December 2018. The amendments do not identify a threshold of significance for GHG emissions, nor do they prescribe assessment methodologies or specific mitigation measures. The amendments encourage lead agencies to consider many factors in performing a CEQA analysis, but preserve the discretion granted by CEQA to lead agencies in making their own determinations based on substantial evidence. The amendments also encourage public agencies to make use of programmatic mitigation plans and programs when they perform individual project analyses.

Senate Bill 375 (2008)
SB 375, the Sustainable Communities and Climate Protection Act, which establishes mechanisms for the development of regional targets for reducing passenger vehicle GHG emissions, was adopted by the State on September 30, 2008. On September 23, 2010, the CARB adopted the vehicular GHG emissions reduction targets that had been developed in consultation with the MPO; the targets require a 6 to 15 percent reduction by 2020 and between 13 to 19 percent reduction by 2035 for each MPO. SB 375 recognizes the importance of achieving significant GHG reductions by working 1 California Air Resources Board (CARB). 2017. California’s 2017 Climate Change Scoping Plan.

Executive Order B-30-15 (2015)
Governor Jerry Brown signed Executive Order B-30-15 on April 29, 2015, which added the immediate target of:
• GHG emissions should be reduced to 40 percent below 1990 levels by 2030.

All State agencies with jurisdiction over sources of GHG emissions were directed to implement measures to achieve reductions of GHG emissions to meet the 2030 and 2050 targets. CARB was directed to update the AB 32 Scoping Plan to reflect the 2030 target, and therefore, is moving forward with the update process. The mid-term target is critical to help frame the suite of policy measures, regulations, planning efforts, and investments in clean technologies and infrastructure needed to continue reducing emissions.

Senate Bill 350 (2015) Clean Energy and Pollution Reduction Act SB 350, signed by Governor Jerry Brown on October 7, 2015, updates and enhances AB 32 by introducing the following set of objectives in clean energy, clean air, and pollution reduction for 2030.
• Raise California’s renewable portfolio standard from 33 percent to 50 percent. • Increasing energy efficiency in buildings by 50 percent by the year 2030.

The 50 percent renewable energy standard will be implemented by the California Public Utilities Commission for the private utilities and by the California Energy Commission for municipal utilities.

Each utility must submit a procurement plan showing it will purchase clean energy to displace other non-renewable resources. The 50 percent increase in energy efficiency in buildings must be achieved through the use of existing energy efficiency retrofit funding and regulatory tools already

Senate Bill 32, California Global Warming Solutions Act of 2016, and Assembly Bill 197 In summer 2016, the Legislature passed, and the Governor signed, SB 32 and AB 197. SB 32 affirms the importance of addressing climate change by codifying into statute the GHG emissions reductions target of at least 40 percent below 1990 levels by 2030 contained in Governor Jerry Brown’s April 2015 Executive Order B-30-15. SB 32 builds on AB 32 and keeps California on the path toward achieving the State’s 2050 objective of reducing emissions to 80 percent below 1990 levels, consistent with an IPCC analysis of the emissions trajectory that would stabilize atmospheric GHG concentrations at 450 parts per million (ppm) CO2e and reduce the likelihood of catastrophic impacts from climate change.

The companion bill to SB 32, AB 197, provides additional direction to CARB related to the adoption of strategies to reduce GHG emissions. Additional direction in AB 197 meant to provide easier public access to air emissions data that are collected by CARB was posted in December 2016.

Senate Bill 100
On September 10, 2018, Governor Jerry Brown signed SB 100, which raises California’s renewables portfolio standard requirements to 60 percent by 2030, with interim targets, and 100 percent by 2045. The bill also establishes a State policy that eligible renewable energy resources and zerocarbon resources supply 100 percent of all retail sales of electricity to California end-use customers and 100 percent of electricity procured to serve all State agencies by December 31, 2045. Under the bill, the State cannot increase carbon emissions elsewhere in the Western grid or allow resource shuffling to achieve the 100 percent carbon-free electricity target.

Executive Order B-55-18
Executive Order B-55-18, signed September 10, 2018, sets a goal “to achieve carbon neutrality as soon as possible, and no later than 2045, and achieve and maintain net negative emissions thereafter.” Executive Order B-55-18 directs CARB to work with relevant State agencies to ensure future Scoping Plans identify and recommend measures to achieve the carbon neutrality goal. The goal of carbon neutrality by 2045 is in addition to other statewide goals, meaning not only should emissions be reduced to 80 percent below 1990 levels by 2050, but that, by no later than 2045, the remaining emissions be offset by equivalent net removals of CO2e from the atmosphere, including through sequestration in forests, soils, and other natural landscapes.

Title 24, Building Standards Code and California Green Building Standards Code In November 2008, the California Building Standards Commission established the California Green Building Standards (CALGreen) Code, which sets performance standards for residential and nonresidential development to reduce environmental impacts and encourage sustainable construction practices. The CALGreen Code addresses energy efficiency, water conservation, material conservation, planning and design, and overall environmental quality. The CALGreen Code is updated every 3 years and was most recently updated in 2019 to include new mandatory

The next set of standards will be adopted in 2022 and apply to projects seeking building permits on or after January 1, 2023.

California Building Efficiency Standards (Title 24, Part 6) The California Building Standards Code, or Title 24 of the California Code of Regulations contains the regulations that govern the construction of buildings in California. Within the Building Standards Code, two parts pertain to the incorporation of both energy efficient and green building elements into land use development. Part 6 is California’s Energy Efficiency Standards for Residential and NonResidential Buildings. These standards were first adopted in 1978 in response to a legislative mandate to reduce California’s energy consumption and are updated on an approximately 3-year cycle to allow consideration and possible incorporation of new energy efficient technologies and methods. All buildings for which an application for a building permit is submitted on or after January 1, 2020, must follow the 2019 standards. The next set of standards is anticipated for release in 2022. Energy efficient buildings require less electricity; therefore, increased energy efficiency reduces fossil fuel consumption and decreases GHG emissions.

Cap and Trade
The development of a cap-and-trade program was included as a key reduction measure of the CARB AB 32 Climate Change Scoping Plan. The cap-and-trade program will help put California on the path to meet its goal of reducing GHG emissions to 1990 levels by 2020 and ultimately achieving an 80 percent reduction from 1990 levels by 2050. The cap-and-trade emissions trading program developed by the CARB took effect on January 1, 2012, with enforceable compliance obligations beginning January 1, 2013. The cap-and-trade program aims to regulate GHG emissions from the largest producers in the State by setting a statewide firm limit, or cap, on allowable annual GHG emissions. The cap was set in 2013 at approximately 2 percent below the emissions forecast for 2020. In 2014, the cap declined approximately 2 percent. Beginning in 2015 and continuing through 2020, the cap has been declining approximately 3 percent annually. The CARB administered the first auction on November 14, 2012, with many of the qualified bidders representing corporations or organizations that produce large amounts of GHG emissions, including energy companies, agriculture and food industries, steel mills, cement companies, and universities. On January 1, 2015, compliance obligation began for distributors of transportation fuels, natural gas, and other fuels.

The cap-and-trade program was initially slated to sunset in 2020, but the passage of SB 398 in 2017 extended the program through 2030.

Executive Order N-79-20
Executive Order N-79-20, signed by Governor Gavin Newsom on September 23, 2020, sets the following goals for the State: 100 percent of in-state sales of new passenger cars and trucks shall be zero-emission by 2035; 100 percent of medium- and heavy-duty vehicles in the State shall be zeroemission by 2045 for all operations where feasible and by 2035 for drayage trucks; and 100 percent of off-road vehicles and equipment in the State shall be zero-emission by 2035, where feasible.

P:\LBL2201\Air Quality\Mosaic LB AQ-GHG Report 10032022.docx (10/03/22) 36 Low Carbon Fuel Standard
In January 2007, EO S-01-07 established a low carbon fuel standard (LCFS). This Executive Order calls for a statewide goal to be established to reduce the carbon intensity of California’s transportation fuels by at least 10 percent by 2020, and that an LCFS for transportation fuels be established for California. The LCFS applies to all refiners, blenders, producers, or importers (“Providers”) of transportation fuels in California, including fuels used by off-road construction equipment. In June 2007, CARB adopted the LCFS under AB 32 pursuant to Health and Safety Code Section 38560.5, and, in April 2009, CARB approved the new rules and carbon intensity reference values with new regulatory requirements taking effect in January 2011. The standards require providers of transportation fuels to report on the mix of fuels they provide and demonstrate they meet the LCFS intensity standards annually. This is accomplished by ensuring that the number of “credits” earned by providing fuels with a lower carbon intensity than the established baseline (or obtained from another party) is equal to or greater than the “deficits” earned from selling higher intensity fuels. In response to certain court rulings, CARB re-adopted the LCFS regulation in September 2015, and the LCFS went into effect on January 1, 2016. In 2018, CARB approved amendments to the regulation to readjust carbon intensity benchmarks to meet California’s 2030 GHG reductions targets under SB 32.

These amendments include opportunities to promote zero-emission vehicle (ZEV) adoption, carbon capture and sequestration, and advanced technologies for decarbonization of the transportation sector.

Advanced Clean Cars Program
In January 2012, CARB approved the Advanced Clean Cars program, which combines the control of GHG emissions and criteria air pollutants, as well as requirements for greater numbers of ZEVs, into a single package of regulatory standards for vehicle model years 2017 through 2025. The new regulations strengthen the GHG standard for 2017 models and beyond. This will be achieved through existing technologies, the use of stronger and lighter materials, and more efficient drivetrains and engines. The program’s ZEVs regulation requires battery, fuel cell, and/or plug-in hybrid electric vehicles to account for up to 15 percent of California’s new vehicle sales by 2025. The program also includes a clean fuels outlet regulation designed to support the commercialization of zero-emission hydrogen fuel cell vehicles planned by vehicle manufacturers by 2015 by requiring increased numbers of hydrogen fueling stations throughout the State. The number of stations will grow as vehicle manufacturers sell more fuel cell vehicles. By 2025, when the rules will be fully implemented, the statewide fleet of new cars and light trucks will emit 40 percent fewer GHGs and 75 percent fewer smog-forming emissions than 2012 model year vehicles.

Executive Order B-48-18
In January 2018, Governor Jerry Brown signed Executive Order B-48-18 requiring all State entities to work with the private sector to have at least 5 million ZEVs on the road by 2030 and install 200 hydrogen fueling stations and 250,000 electric vehicle charging stations by 2025. It specifies that 10,000 of the electric vehicle charging stations should be direct current fast chargers. This order also requires all State entities to continue to partner with local and regional governments to streamline the installation of ZEV infrastructure. The Governor’s Office of Business and Economic Development is required to publish a Plug-in Charging Station Design Guidebook and update the 2015 Hydrogen Station Permitting Guidebook to aid in these efforts. All State entities are required to participate in

Regional Regulations
South Coast Air Quality Management District
In 2008, the SCAQMD formed a Working Group to identify GHG emissions thresholds for land use projects that could be used by local lead agencies in the Basin. The Working Group developed several different options that are contained in the SCAQMD 2008 draft guidance document titled Interim CEQA GHG Significance Threshold for Stationary Sources, Rules and Plans1 that could be applied by lead agencies. On September 28, 2010, SCAQMD Working Group Meeting No. 15 provided further guidance, including a tiered approach for evaluating GHG emissions for development projects where the SCAQMD is not the lead agency. The SCAQMD has not presented a finalized version of these thresholds to the governing board.

The SCAQMD identifies the emissions level for which a project would not be expected to substantially conflict with any State legislation adopted to reduce statewide GHG emissions. As such, the utilization of a service population represents the rates of emissions needed to achieve a fair share of the State’s mandated emissions reductions. Overall, the SCAQMD identifies a GHG efficiency level that, when applied statewide or to a defined geographic area, would meet the year 2020 and post-2020 emissions targets as required by AB 32 and SB 32. If projects are able to achieve targeted rates of emissions per the service population, the State will be able to accommodate expected population growth and achieve economic development objectives, while also abiding by AB 32’s emissions target and future post-2020 targets.

Southern California Association of Governments
On September 3, 2020, SCAG adopted Connect SoCal.2 In general, Connect SoCal outlines a development pattern for the region, which, when integrated with the transportation network and other transportation measures and policies, would reduce vehicle miles traveled from automobiles and light-duty trucks and thereby reduce GHG emissions from these sources. For the SCAG region, CARB has set GHG reduction targets at 8 percent below 2005 per capita emissions levels by 2020, and 19 percent below 2005 per capita emissions levels by 2035. Connect SoCal lays out a strategy for the region to meet these targets. Overall, Connect SoCal is meant to provide growth strategies that will achieve the regional GHG emissions reduction targets. Land use strategies to achieve the region’s targets include planning for new growth around high-quality transit areas and livable corridors and creating neighborhood mobility areas to integrate land use and transportation and 1 South Coast Air Quality Management District. 2008a.

City of Long Beach Climate Action and Adaptation Plan
The City of Long Climate Action and Adaptation Plan (CAAP)2 was adopted on August 16, 2022 and is a comprehensive planning document outlining the City’s proposed approach both to address climate impacts on Long Beach and to reduce Long Beach’s impact on the climate by reducing GHG emissions. The CAAP provides a framework to reduce the City's GHG footprint (climate action) and ensure the community and physical assets are better protected from the impacts of climate change (climate adaptation). The vision of the CAAP is to create a more sustainable, resilient, and equitable city by addressing climate change in a way that remedies existing environmental health disparities while also improving health, quality of life, and enhancing economic vitality throughout Long Beach.

The CAAP includes a roadmap for implementing new polices, programs, incentives, requirements, projects, and initiatives in the immediate future, as well as longer-term actions that will need to be studied further while monitoring how the climate continues to change and evaluating the effectiveness of actions taken. The CAAP also includes the CAAP Consistency Review Checklist to be used for future projects to determine their consistency with the CAAP.

City of Long Beach Downtown Plan
The Downtown Plan PEIR identified the following mitigation measures that would apply to the proposed project and that would help to reduce and avoid potential impacts related to GHG emissions:
• Mitigation Measure GHG-1(a): Implement Mitigation Measure AQ-1. Implementation of the mitigation measures described in Section 4.2, Air Quality, of the PEIR, which would reduce construction emissions of criteria air pollutants and precursors, would also act to reduce GHG emissions associated with implementation of the Project. The construction mitigation measures for exhaust emissions are relevant to the global climate change impact because both criteria air pollutant and GHG emissions are frequently associated with combustion byproducts. • Mitigation Measure GHG-1(b): Implement Additional Measures to Control ConstructionGenerated GHG Emissions. To further reduce construction-generated GHG emissions, the project applicant(s) of all public and private developments shall implement all feasible measures for reducing GHG emissions associated with construction that are recommended by the City and/or SCAQMD at the time individual portions of the site undergo construction, including those specified in the mitigation recommendations in the SCAQMD CEQA Handbook or SCAQMD’s 1 Southern California Association of Governments. 2020.

http://www.aqmd.gov/ceqa/handbook/mitigation/MM_intro.html. Such measures may reduce GHG exhaust emissions from the use of onsite equipment, worker commute trips, and truck trips carrying materials and equipment to and from the project site, as well as GHG emissions embodied in the materials selected for construction (e.g., concrete). Other measures may pertain to the materials used in construction. Prior to the construction of each development phase, the project applicant(s) shall obtain the most current list of GHG-reduction measures that are recommended by the City and/or SCAQMD and stipulate that these measures be implemented during the appropriate construction phase. The project applicant(s) for any particular development phase may submit to the City a report that substantiates why specific measures are considered infeasible for construction of that particular development phase and/or at that point in time. The report, including the substantiation for not implementing particular GHG-reduction measures, shall be approved by the City.

The City’s recommended measures for reducing construction-related GHG emissions at the time of writing the PEIR are listed below and the project applicant(s) shall, at a minimum, be required to implement the following:
○ Improve fuel efficiency from construction equipment:
■ reduce unnecessary idling (modify work practices, install auxiliary power for driver comfort),
■ perform equipment maintenance (inspections, detect failures early, corrections), ■ train equipment operators in proper use of equipment, ■ use the proper size of equipment for the job, and
■ use equipment with new technologies (repowered engines, electric drive trains). ○ Use alternative fuels for electricity generators and welders at construction sites such as propane or solar, or use electrical power.
○ Use a CARB-approved low-carbon fuel, such as biodiesel or renewable diesel for construction equipment (emissions of NOx from the use of low carbon fuel must be reviewed and increases mitigated). Additional information about low-carbon fuels is available from CARB’s Low Carbon Fuel Standard Program. ○ Encourage and provide carpools, shuttle vans, transit passes and/or secure bicycle parking for construction worker commutes.
○ Reduce electricity use in the construction office by using compact fluorescent bulbs, powering off computers every day, and replacing heating and cooling units with more efficient ones.

○ Use locally sourced or recycled materials for construction materials (goal of at least 20 percent based on costs for building materials, and based on volume for roadway, parking lot, sidewalk, and curb materials).
○ Minimize the amount of concrete used for paved surfaces or use a low carbon concrete option.
○ Produce concrete onsite if determined to be less emissive than transporting ready mix. ○ Use EPA-certified SmartWay trucks for deliveries and equipment transport. Additional information about the SmartWay Transport Partnership Program is available from CARB’s Heavy-Duty Vehicle GHG Measure and EPA.
○ Develop a plan to efficiently use water for adequate dust control. This may consist of the use of non-potable water from a local source
• Mitigation Measure GHG-2(a): Implement Mitigation Measure AQ-3. Implementation of the mitigation measures described in Section 4.2, which would reduce operational emissions of criteria air pollutants and precursors, would also act to reduce GHG emissions associated with implementation of the Project. The operational mitigation measures for exhaust emissions are relevant to the global climate change impact because both criteria air pollutant and GHG emissions are frequently associated with combustion byproducts. • Mitigation Measure GHG-2(b): Implement Additional Measures to Reduce Operational GHG Emissions. For each increment of new development within the Project area requiring a discretionary approval (e.g., tentative subdivision map, conditional use permit, improvement plan), measures that reduce GHG emissions to the extent feasible and to the extent appropriate with respect to the state’s progress at the time toward meeting GHG emissions reductions required by the California Global Warming Solutions Act of 2006 (AB 32) shall be imposed, as follows:
○ The project applicant shall incorporate feasible GHG reduction measures that, in combination with existing and future regulatory measures developed under AB 32, will reduce GHG emissions associated with the operation of future project development phases and supporting roadway and infrastructure improvements by an amount sufficient to achieve the goal of 6.6 CO2e/SP/year, if it is feasible to do so. The feasibility of potential GHG reduction measures shall be evaluated by the City at the time each phase of development is proposed to allow for ongoing innovations in GHG reduction technologies and incentives created in the regulatory environment.
○ For each increment of new development, the project applicant shall obtain a list of potentially feasible GHG reduction measures to be considered in the development design from the City. The City’s list of potentially feasible GHG reduction measures shall reflect the

The project applicant(s) shall then submit to the City a mitigation report that contains an analysis demonstrating which GHG reduction measures are feasible for the associated reduction in GHG emissions, and the resulting CO2e/SP/year metric. The report shall also demonstrate why measures not selected are considered infeasible. The mitigation report must be reviewed and approved by the City for the project applicant(s) to receive the City’s discretionary approval for the applicable increment of development. In determining what measures should appropriately be imposed by a local government under the circumstances, the following factors shall be considered:
■ The extent to which rates of GHG emissions generated by motor vehicles traveling to, from, and within the Project site are projected to decrease over time as a result of regulations, policies, and/or plans that have already been adopted or may be adopted in the future by CARB or other public agency pursuant to AB 32, or by EPA; ■ The extent to which mobile-source GHG emissions, which at the time of writing the PEIR comprise a substantial portion of the state’s GHG inventory, can also be reduced through design measures that result in trip reductions and reductions in trip length; ■ The extent to which GHG emissions emitted by the mix of power generation operated by SCE, the electrical utility that will serve the Project site, are projected to decrease pursuant to the Renewables Portfolio Standard required by SB 1078 and SB 107, as well as any future regulations, policies, and/or plans adopted by the federal and State governments that reduce GHG emissions from power generation; ■ The extent to which replacement of CCR Title 24 with the California Green Building Standards Code or other similar requirements will result in new buildings being more energy efficient and consequently more GHG efficient;
■ The extent to which any stationary sources of GHG emissions that would be operated on a proposed land use (e.g., industrial) are already subject to regulations, policies, and/or plans that reduce GHG emissions, particularly any future regulations that will be developed as part of CARB’s implementation of AB 32, or other pertinent regulations on stationary sources that have the indirect effect of reducing GHG emissions; ■ The extent to which the feasibility of existing GHG reduction technologies may change in the future, and to which innovation in GHG reduction technologies will continue, effecting cost-benefit analyses that determine economic feasibility; and ■ Whether the total costs of proposed mitigation for GHG emissions, together with other mitigation measures required for the proposed development, are so great that a reasonably prudent property owner would not proceed with the project in the face of such costs.
○ In considering how much, and what kind of, mitigation is necessary in light of these factors, the following list of options shall be considered, though the list is not intended to be

Energy Efficiency
■ Include clean alternative energy features to promote energy self-sufficiency (e.g., photovoltaic cells, solar thermal electricity systems, small wind turbines). ■ Design buildings to meet CEC Tier II requirements (e.g., exceeding the requirements of Title 24 [as of 2007] by 20 percent).
■ Site buildings to take advantage of shade and prevailing winds and design landscaping and sun screens to reduce energy use.
■ Install efficient lighting in all buildings (including residential). Also install lighting control systems, where practical. Use daylight as an integral part of lighting systems in all buildings.
■ Install light-colored “cool” pavements, and strategically located shade trees along all bicycle and pedestrian routes.

■ With the exception of ornamental shade trees, use water-efficient landscapes with native, drought-resistant species in all public area and commercial landscaping. Use water-efficient turf in parks and other turf-dependent spaces. ■ Install the infrastructure to use reclaimed water for landscape irrigation and/or washing cars.
■ Install water-efficient irrigation systems and devices, such as soil moisture-based irrigation controls.
■ Design buildings and lots to be water efficient. Only install water-efficient fixtures and appliances.
■ Restrict watering methods (e.g., prohibit systems that apply water to non-vegetated surfaces) and control runoff. Prohibit businesses from using pressure washers for cleaning driveways, parking lots, sidewalks, and street surfaces. These restrictions should be included in the Covenants, Conditions, and Restrictions of the community.

SETTING

ATTAINMENT STATUS
The CARB is required to designate areas of the State as attainment, nonattainment, or unclassified for all State standards. An attainment designation for an area signifies that pollutant concentrations did not violate the standard for that pollutant in that area. A nonattainment designation indicates that a pollutant concentration violated the standard at least once, excluding those occasions when a violation was caused by an exceptional event, as defined in the criteria. An unclassified designation signifies that data do not support either an attainment or nonattainment status. The CCAA divides districts into moderate, serious, and severe air pollution categories, with increasingly stringent control requirements mandated for each category.

The USEPA designates areas for O3, CO, and NO2 as either does not meet the primary standards, cannot be classified, or better than national standards. For SO2, areas are designated as does not meet the primary standards, does not meet the secondary standards, cannot be classified, or better than national standards.

Table F provides a summary of the attainment status for the Basin with respect to NAAQS and CAAQS.

The annual average temperature varies little throughout the Basin, ranging from the low to middle 60s°F. With a more pronounced oceanic influence, coastal areas show less variability in annual minimum and maximum temperatures than inland areas. The climatological station closest to the site is the Long Beach Station.
1 The monthly average maximum temperature recorded at this station ranged from 65.2°F in January to 80.7°F in August, with an annual average maximum of 72.4°F. The monthly average minimum temperature recorded at this station ranged from 44.8°F in January to

62.1°F in August, with an annual average minimum of 53.4°F. These levels are still representative of the project area.

The majority of annual rainfall in the Basin occurs between November and March. Summer rainfall is minimal and is generally limited to scattered thundershowers in coastal regions and slightly heavier showers in the eastern portion of the Basin and along the coastal side of the mountains. Average monthly rainfall at the Long Beach station varied from 2.88 inches in January to 0 inch in July, with an annual total of 12.72 inches. Patterns in monthly and yearly rainfall totals are unpredictable due to fluctuations in the weather.

The Basin experiences a persistent temperature inversion (increasing temperature with increasing altitude) as a result of the Pacific high. This inversion limits the vertical dispersion of air contaminants, holding them relatively near the ground. As the sun warms the ground and the lower air layer, the temperature of the lower air layer approaches the temperature of the base of the inversion (upper) layer until the inversion layer finally breaks, allowing vertical mixing with the lower layer. This phenomenon is observed in mid-afternoon to late afternoon on hot summer days when the air appears to clear up suddenly. Winter inversions frequently break by midmorning.

Winds in the project area blow predominantly from the south-southwest, with relatively low velocities. Wind speeds in the project area average about 5 miles per hour. Summer wind speeds average slightly higher than winter wind speeds. Low average wind speeds, together with a persistent temperature inversion, limit the vertical dispersion of air pollutants throughout the Basin. Strong, dry, north or northeasterly winds, known as Santa Ana winds, occur during the fall and winter months, dispersing air contaminants. The Santa Ana conditions tend to last for several days at a time.

The combination of stagnant wind conditions and low inversions produces the greatest pollutant concentrations. On days of no inversion or high wind speeds, ambient air pollutant concentrations are the lowest. During periods of low inversions and low wind speeds, air pollutants generated in urbanized areas are transported predominantly onshore into Riverside and San Bernardino counties.

In the winter, the greatest pollution problems are CO and NOx because of extremely low inversions and air stagnation during the night and early morning hours. In the summer, the longer daylight hours and brighter sunshine combine to cause a reaction between hydrocarbons and NOx to form photochemical smog. Smog is a general term that is naturally occurring fog that has become mixed with smoke or pollution. In this context it is better described as a form of air pollution produced by 1 Western Regional Climate Center. n.d. Recent Climate in the West.

AIR QUALITY MONITORING RESULTS
Air quality monitoring stations are located throughout the nation and are maintained by the local air pollution control district and State air quality regulating agencies. The SCAQMD, together with the CARB, maintains ambient air quality monitoring stations in the Basin. The air quality monitoring stations closest to the project site are at 2425 Webster Street in Long Beach, 1710 East 20th Street in Signal Hill, 1305 East Pacific Coast Hwy in Long Beach, 700 North Bullis Road in Compton, and 1630 North Main Street in Los Angeles.

Pollutant monitoring results for years 2019 to 2021 at the Long Beach, Signal Hill, Compton, and Los Angeles air quality monitoring stations, shown in Table G, indicate that air quality in the area has generally been good. As indicated in the monitoring results, the federal PM10 standard had one exceedance in 2019 and no exceedances in 2020 and 2021. The State PM10 standard had 4 exceedances in 2019, 3 exceedances in 2020, and 0 exceedances in 2021. The federal PM2.5 levels had 0 exceedances in 2019, and an unknown number of exceedances in 2020 and 2021. The 1-hour ozone standards exceed the State standard 0 times in 2019, 4 times in 2020, and an unknown number of times in 2021. The 8-hour ozone State and federal standards were exceeded 4 times in 2020 only. The CO, SO2, and NO2 standards were not exceeded in this area during the 3-year period.

GREENHOUSE GAS EMISSIONS INVENTORY
An emissions inventory that identifies and quantifies the primary human-generated sources and sinks of GHGs is a well-recognized and useful tool for addressing climate change. This section summarizes the latest information on global, United States, and California GHG emission inventories.

Global Emissions
Worldwide emissions of GHGs in 2018 totaled 25.6 billion metric tons of CO2e. Global estimates are based on country inventories developed as part of the programs of the United Nations Framework Convention on Climate Change.

P:\LBL2201\Air Quality\Mosaic LB AQ-GHG Report 10032022.docx (10/03/22) 48 United States Emissions
In 2019, the year for which the most recent data are available, the United States emitted about 6,558 MMT CO2e. Overall, emissions in 2019 decreased by 1.7 percent since 2018 and were 13 percent below 2005 levels. This decrease was driven largely by a decrease in emissions from fossil fuel combustion resulting from a decrease in total energy use in 2019 compared to 2018 and a continued shift from coal to natural gas and renewables in the electric power sector. Of the six major sectors – residential, commercial, agricultural, industry, transportation, and electricity generation – transportation accounted for the highest amount of GHG emissions in 2019 (approximately 29 percent), with electricity generation second at 25 percent and emissions from industry third at 23 percent.1
State of California Emissions
The State emitted 418.2 MMT CO2e in 2019, 7.2 MMT CO2e lower than 2018 levels and almost 13 MMT CO2e below the 2020 GHG Limit of 431 MMT CO2e.2 The CARB estimates that transportation was the source of approximately 40 percent of the State’s GHG emissions in 2019, followed by industrial sources at approximately 21 percent and electricity generation at 14 percent. The remaining sources of GHG emissions were agriculture at 8 percent, residential activities at 7 percent, commercial activities at 4 percent, high GWP at 5 percent, and waste at 2 percent.3 City of Long Beach
As part of preparing the City’s CAAP, the City developed baseline GHG emissions inventories for the year 2015 for production and consumption “jurisdictional emissions”—those emissions sources over which the City and community have some amount of influence. These jurisdictional emissions sources are primarily aligned with the BASIC inventory methodology described in the CAAP, except for the removal of port-based waterborne activities like cargo shipping and aircraft activities at the Long Beach Airport.

As shown in Table H below, the City’s 2015 total jurisdictional production emissions were 2,799,123 MT CO2e per year with the majority coming from stationary sources (49 percent) and transportation contributing (44 percent). The remaining approximately 6 percent comes from solid waste and wastewater.

In addition, a consumption emissions inventory of the City of Long Beach was conducted for the CAAP based on the average carbon generated in the production and use of goods and services by households in Long Beach. Consumption emissions are categorized as energy, transportation, or goods and services. As shown in Table I below, the City’s 2015 total consumption emissions were 1 United States Environmental Protection Agency. 2021. Inventory of U.S. Greenhouse Gas Emissions and Sinks: 1990-2019.

METHODOLOGY
The methodology used to estimate air quality and GHG impacts is described below.

CONSTRUCTION EMISSIONS
Construction activities can generate a substantial amount of air pollution. Construction activities are considered temporary; however, short term impacts can contribute to exceedances of air quality standards. Construction activities include site preparation, earthmoving, and general construction.

The emissions generated from these common construction activities include fugitive dust from soil disturbance, fuel combustion from mobile heavy-duty diesel and gasoline powered equipment, portable auxiliary equipment, and worker commute trips.

The California Emission Estimator Model version 2020.4.0 (CalEEMod) computer program was used to calculate emissions from on-site construction equipment and emissions from worker and vehicle trips to the site (provided as Appendix A). As discussed in the Project Description, construction of the proposed project is anticipated to begin in the fourth quarter of 2023 and would end the fourth quarter of 2027. Based on the preliminary grading plans, 7,610 cubic yards of soil would be exported from the project site, which was included in CalEEMod. In addition, the proposed project would include the demolition of approximately 197,523 square feet, which was also included in CalEEMod.

In addition, consistent with Downtown Plan PEIR Mitigation Measures AQ-1(c), this analysis assumes the use of Tier 4 construction equipment and use of low-VOC paint. In addition, this analysis assumes compliance with SCAQMD Rule 403 measures. All other construction details are not yet known; therefore, default assumptions (e.g., construction worker and truck trips and fleet activities) from CalEEMod were used.

OPERATIONAL EMISSIONS
Consistent with the SCAQMD guidance for estimating emissions associated with land use development projects, the CalEEMod computer program was used to calculate the long-term operational emissions associated with the project. As discussed in the Project Description, the proposed project would replace the existing commercial buildings to include the construction of 900 residential dwelling units and 38,405 square feet of commercial uses. Therefore, the existing conditions analysis was conducted using land use code Strip Mall. Although the existing site includes 197,513 square feet of existing uses, only 39,224 square feet is currently occupied, which was included in this analysis. The proposed project analysis was conducted using land codes Apartments Mid Rise, Strip Mall, and Enclosed Parking Structure. Trip generation rates in CalEEMod were based on the TIA prepared by LSA, which identifies that the existing conditions typically generate approximately 2,136 average daily trips and the proposed project would generate approximately 5,645 average daily trips.1 As such, the proposed project would result in a net increase in 3,509 average daily trips. In addition, this analysis assumes the use of low-VOC paint consistent with Downtown Plan PEIR Mitigation Measure AQ-1(c) and exceedance of current Title 24 standards by 20 percent and use of solar PV consistent with Downtown Plan PEIR Mitigation Measure AQ-2. 1 LSA, 2022. op. cit.

GREENHOUSE GAS ANALYSIS
GHG emissions associated with the project would occur over the short-term from construction activities, consisting primarily of emissions from equipment exhaust. There would also be long-term GHG emissions associated with project-related vehicular trips. Recognizing that the field of global climate change analysis is rapidly evolving, the approaches advocated most recently indicate that for determining a project’s contribution to GHG emissions, lead agencies should calculate, or estimate, emissions from vehicular traffic, energy consumption, water conveyance and treatment, waste generation, construction activities, and any other significant source of emissions within the project area. The CalEEMod results were used to quantify GHG emissions generated by the project.

THRESHOLDS OF SIGNIFICANCE
The State CEQA Guidelines indicate that a project would normally have a significant adverse air quality impact if project-generated pollutant emissions would:
• Conflict with or obstruct implementation of the applicable air quality plan; • Result in a cumulatively considerable net increase of any criteria pollutant for which the project is nonattainment under applicable federal or state ambient air quality standards; • Expose sensitive receptors to substantial pollutant concentrations; or • Result in other emissions (such as those leading to odors) affecting a substantial number of people.

The State CEQA Guidelines indicate that a project would normally have a significant adverse greenhouse gas emission impact if the project would:
• Generate greenhouse gas emissions, either directly or indirectly, that may have a significant impact on the environment; or
• Conflict with an applicable plan, policy or regulation adopted for the purpose of reduction the emissions of greenhouse gases.

Certain air districts (e.g., SCAQMD) have created guidelines and requirements to conduct air quality analysis. SCAQMD’s current guidelines, the CEQA Air Quality Handbook with associated updates, were followed in this assessment of air quality and GHG impacts for the proposed project.

REGIONAL EMISSIONS THRESHOLDS
SCAQMD has established daily emissions thresholds for construction and operation of a proposed project in the Basin. The emissions thresholds were established based on the attainment status of the Basin with regard to air quality standards for specific criteria pollutants. Because the concentration standards were set at a level that protects public health with an adequate margin of safety, these emissions thresholds are regarded as conservative and would overstate an individual project’s contribution to health risks.

Table J lists the CEQA significance thresholds for construction and operational emissions established for the Basin. Projects in the Basin with construction- or operation-related emissions that exceed any of their respective emission thresholds would be considered significant under SCAQMD guidelines. These thresholds, which SCAQMD developed and that apply throughout the Basin, apply as both project and cumulative thresholds. If a project exceeds these standards, it is considered to have a project-specific and cumulative impact.

LOCALIZED IMPACTS ANALYSIS
The SCAQMD published its Final Localized Significance Threshold Methodology in July 2008, recommending that all air quality analyses include an assessment of air quality impacts to nearby sensitive receptors.1 This guidance was used to analyze potential localized air quality impacts associated with construction of the proposed project. Localized significance thresholds (LST) are developed based on the size or total area of the emission source, the ambient air quality in the source receptor area, and the distance to the project. Sensitive receptors include residences, schools, hospitals, and similar uses that are sensitive to adverse air quality.

LSTs are based on the ambient concentrations of that pollutant within the project source receptor area (SRA) and the distance to the nearest sensitive receptor. For the proposed project, the appropriate SRA for the LST is the nearby South Coastal LA County (SRA 4). SCAQMD provides LST screening tables for 25, 50, 100, 200, and 500-meter source-receptor distances. As identified above, the closest sensitive receptors to the project area include multifamily residential uses approximately 80 feet west of the project site across The Promenade North. In cases where receptors may be closer than 82 feet (25 meters), any distances within the 82-foot (25-meter) buffer zone can be used. As such, the minimum distance of 82 feet was used. Based on the anticipated construction equipment, it is assumed that the maximum daily disturbed acreage for the proposed project would be 3.5 acres during construction.2 Once operational, the 5-acre threshold would apply.

LOCAL MICROSCALE CONCENTRATION STANDARDS
The significance of localized project impacts under CEQA depends on whether ambient CO levels in the vicinity of the project are above or below State and federal CO standards. Because ambient CO levels are below the standards throughout the Basin, a project would be considered to have a significant CO impact if project emissions result in an exceedance of one or more of the 1-hour or 8-hour standards. The following are applicable local emission concentration standards for CO:
• California State 1-hour CO standard of 20 ppm
• California State 8-hour CO standard of 9 ppm

GLOBAL CLIMATE CHANGE
Section 15064.4 of the State CEQA Guidelines states “A lead agency should make a good-faith effort, based to the extent possible on scientific and factual data, to describe, calculate or estimate the amount of greenhouse gas emissions resulting from a project.” In performing that analysis, the lead agency has discretion to determine whether to use a model or methodology to quantify GHG emissions, or to rely on a qualitative analysis or performance-based standards. In making a determination as to the significance of potential impacts, the lead agency then considers the extent to which the project may increase or reduce GHG emissions compared to the existing environmental setting, whether the project emissions exceed a threshold of significance that the lead agency determines applies to the project, and the extent to which the project complies with regulations or requirements adopted to implement a Statewide, regional, or local plan for the reduction or mitigation of GHG emissions.

Therefore, consistent with the State CEQA Guidelines, Section 15183.5, if a project is consistent with an adopted qualified Greenhouse Gas Reduction Strategy that meets the standards, it can be presumed that the project would not have significant GHG emission impacts. The City of Long Beach CAAP meets the requirements of State CEQA Guidelines, Section 15183.5; therefore, the proposed project will be evaluated for consistency with the City’s CAAP.

Based on the City’s CAAP, the following steps must be completed to demonstrate conformance with the City’s CAAP:
• Step 1: Demonstrate consistency with the City’s General Plan. All projects must demonstrate consistency with the City’s General Plan and the existing land use designation of the 2019 Land

Alternatively, if a project is not consistent with the land use designation of the 2019 LUE, the project must identify an alternative compliance mechanism. • Step 2: Determine if project screens out of CAAP Action consistency. If the project would achieve emissions of 1.4 metric tons of CO2e per year per service population or less, the project is considered consistent with the CAAP Actions and the analysis is complete. • Step 3: Demonstrate consistency with the CAAP GHG Emission Reduction Actions. Table 1 of the CAAP Checklist identifies the CAAP Action consistency requirements for projects. Projects must demonstrate consistency with the CAAP Action requirements or document why the strategies are not applicable or are infeasible.
• Step 4: Identify alternative project emission reduction measures and additional GHG reductions.

Projects that propose alternative GHG emission reduction measures to those identified in Table 1 of the CAAP Checklist or propose to include additional GHG emission reduction measures shall provide a summary explanation of the proposed measures and demonstrate GHG reductions achievable though the proposed measures. Documentation for these alternative or additional project measures shall be documented in Table 2 of the CAAP Checklist. • Step 5: Demonstrate consistency with the CAAP Adaptation Actions. Table 3 of the CAAP Checklist identifies the CAAP Adaptation Action consistency requirements for projects. Projects must demonstrate consistency with the CAAP Adaptation Action requirements listed in Table 3 of the CAAP Checklist or document why the strategies are not applicable or are infeasible.

IMPACTS ANALYSIS
This section identifies the air quality and GHG emissions impacts associated with implementation of the proposed project. The results of the impact analyses are then compared to applicable thresholds of significance.

AIR QUALITY IMPACTS
Air pollutant emissions associated with the project would occur over the short term from construction activities and over the long term from operational activities associated with the proposed land uses
Consistency with Applicable Air Quality Plans
A consistency determination plays an essential role in local agency project review by linking local planning and unique individual projects to the air quality plans. A consistency determination fulfills the CEQA goal of fully informing local agency decision-makers of the environmental costs of the project under consideration at a stage early enough to ensure that air quality concerns are addressed. Only new or amended General Plan elements, Specific Plans, and significantly unique projects need to undergo a consistency review due to the air quality plan strategy being based on projections from local General Plans.

With respect to determining the proposed project consistency with AQMP growth assumptions, the projections in the AQMP for achieving air quality goals are based on assumptions in SCAG’s RTP/SCS regarding population, housing, and growth trends. Although the SCAG’s 2020–2045 RTP/SCS is the most recent adopted version, the AQMP was prepared with growth projections from the prior 2016- 2040 RTP/SCS. As such, this analysis includes a discussion of SCAG’s 2016-2040 RTP/SCS and SCAG’s 2020–2045 RTP/SCS.

According to SCAG’s 2016–2040 RTP/SCS, the forecasted population and employment for Long Beach in 2012 was 466,300 residents and 153,200 employees and in 2040 is anticipated to have a population and employment of 484,500 residents and 181,700 employees.1 Therefore, the forecasted population for Long Beach will grow by approximately 18,200 residents and 28,500 employees between 2012 and 2040. In addition, according to the SCAG’s 2020–2045 RTP/SCS, the forecasted population and employment for Long Beach in 2016 was 470,900 residents and 155,900 employees and in 2045 is anticipated to have a population and employment of 489,600 residents and 185,400 employees.2 Therefore, the forecasted population for Long Beach will grow by approximately 18,700 residents and 29,500 employees between 2016 and 2045. 1 Southern California Association of Governments. 2016.

P:\LBL2201\Air Quality\Mosaic LB AQ-GHG Report 10032022.docx (10/03/22) 57 As identified in the City’s LUE, the average household size is 2.92 people for owner-occupied units and 2.74 people for renter-occupied units.
1 The proposed project would include renter-occupied
units; therefore, development of the project site with 900 new dwelling units could house 2,466 residents. Thus, the residents of the proposed project would account for approximately 14 percent of the population growth forecasted by SCAG in Long Beach between 2012 and 2040 and approximately 13 percent of the population growth forecasted by SCAG in Long Beach between 2016 and 2045. In addition, the proposed project would include 38,405 square feet of commercial uses; however, the existing site includes 197,513 square feet of existing uses with 39,224 square feet currently occupied. Therefore, this analysis assumes that the proposed project would not generate a substantial amount of new employees.

Because the project falls within the previously assumed growth projections for the City, the additional units from the proposed project would not interfere with SCAQMD’s goals for improving air quality in the region because they would house growth that SCAQMD already projected for the City. Therefore, the proposed project would not conflict with the 2016 AQMP and, as such, would not jeopardize attainment of the CAAQS and NAAQS in the area under the jurisdiction of the SCAQMD.

Furthermore, as shown in Tables N and O below, construction and operation of the project would not result in an exceedance of the SCAQMD’s thresholds for criteria pollutants; therefore, the project is not expected to result in a violation of air quality standards. Due to these factors, it can be concluded that the proposed project would be consistent with the projections in the AQMP.

Criteria Pollutant Analysis
The following sections describe the proposed project’s construction- and operation-related air quality impacts and localized impacts.

Construction Emissions
During construction, short-term degradation of air quality may occur due to the release of particulate emissions generated by demolition, grading, paving, building, and other activities.

Emissions from construction equipment are also anticipated and would include CO, NOx, VOC, directly-emitted particulate matter (PM2.5 and PM10), and TACs such as diesel exhaust particulate matter.

Project construction activities would include demolition, grading, site preparation, building, paving, and architectural coating activities. Construction-related effects on air quality from the proposed project would be greatest during the site preparation phase due to the disturbance of soils. If not properly controlled, these activities would temporarily generate particulate emissions. Sources of fugitive dust would include disturbed soils at the construction site. Unless properly controlled, vehicles leaving the site would deposit dirt and mud on local streets, which could be an additional source of airborne dust after it dries. PM10 emissions would vary from day to day, depending on the 1 City of Long Beach. 2019. City of Long Beach General Plan Land Use Element. December. Website:

P:\LBL2201\Air Quality\Mosaic LB AQ-GHG Report 10032022.docx (10/03/22) 58 nature and magnitude of construction activity and local weather conditions. PM10 emissions would depend on soil moisture, silt content of soil, wind speed, and the amount of operating equipment.

Larger dust particles would settle near the source, while fine particles would be dispersed over greater distances from the construction site.

Water or other soil stabilizers can be used to control dust, resulting in emission reductions of 50 percent or more. The SCAQMD has established Rule 403: Fugitive Dust, which would require the applicant to implement measures that would reduce the amount of particulate matter generated during the construction period. The CalEEMod analysis assumed that the proposed project would water exposed areas twice per day, reducing PM2.5 and PM10 emissions by 55 percent, consistent with Rule 403.

In addition to dust-related PM10 emissions, heavy trucks and construction equipment powered by gasoline and diesel engines would generate CO, SO2, NOx, VOCs and some soot particulate (PM2.5 and PM10) in exhaust emissions. If construction activities were to increase traffic congestion in the area, CO and other emissions from traffic would increase slightly while those vehicles idle in traffic.

These emissions would be temporary in nature and limited to the immediate area surrounding the construction site.

Construction emissions were estimated for the project using CalEEMod. Table L lists the tentative project construction schedule for the project based on an estimated start date in the fourth quarter of 2023 and end the fourth quarter of 2027. Table M lists the potential construction equipment to be used during project construction under each phase of construction. Construction-related emissions are presented in Table N.

Operational Air Quality Impacts
Long-term air pollutant emission impacts are those typically associated with mobile sources (e.g., vehicle trips), energy sources (e.g., electricity and natural gas), and area sources (e.g., architectural coatings and the use of landscape maintenance equipment).

PM10 emissions result from running exhaust, tire and brake wear, and the entrainment of dust into the atmosphere from vehicles traveling on paved roadways. Entrainment of PM10 occurs when vehicle tires pulverize small rocks and pavement and the vehicle wakes generate airborne dust. The contribution of tire and brake wear is small compared to the other PM emission processes.

Gasoline-powered engines have small rates of particulate matter emissions compared with dieselpowered vehicles.

Energy source emissions result from activities in buildings for which electricity and natural gas are used. The quantity of emissions is the product of usage intensity (i.e., the amount of electricity or natural gas) and the emission factor of the fuel source. The primary sources of energy demand for the proposed project would include building mechanical systems, such as heating and air conditioning, lighting, and plug-in electronics, such as refrigerators or computers. Greater building or appliance efficiency reduces the amount of energy for a given activity and thus lowers the resultant emissions. The emission factor is determined by the fuel source, with cleaner energy sources, like renewable energy, producing fewer emissions than conventional sources.

Typically, area source emissions consist of direct sources of air emissions at the project site, including architectural coatings and the use of landscape maintenance equipment. Area source emissions associated with the project would include emissions from the use of architectural coatings, consumer products, and landscaping equipment. The residential units would not include wood-burning hearths.

Long-term operation emissions associated with the existing uses and proposed project were calculated using CalEEMod. Model results are shown in Table O below. CalEEMod output sheets are provided as Appendix A.

The results shown in Table O indicate the project would not exceed the significance criteria for VOC, NOx, CO, SOx, PM10, or PM2.5 emissions; therefore, the proposed project would not have a significant effect on regional air quality. As discussed previously, the Downtown Plan PEIR identified mitigation measures that would apply to the proposed project. With implementation of Downtown Plan PEIR Mitigation Measure AQ-2, operation of the project would not result in a cumulatively considerable net increase of any criteria pollutant for which the project is nonattainment under an applicable federal or State ambient air quality standard.

Localized Significance Analysis
Project construction and operation emissions were compared to the LST screening tables in SRA 4, based on a 25-meter source-receptor distance and a disturbed acreage of 3.5-acres for construction and 5.0 acres for operation. The results of the LST analysis, are summarized in Table P and Table Q.

Construction emissions would vary throughout the project construction period and the maximum localized emissions would only occur temporarily during the overlapping building construction and architectural coating phases. As shown in Table P, the maximum daily localized construction emissions would not exceed the SCAQMD LST. In addition, as indicated in Table Q, the project would not result in an exceedance of the SCAQMD LST during project operation.

Long-Term Microscale (CO Hot Spot) Analysis
Vehicular trips associated with the proposed project would contribute to congestion at intersections and along roadway segments in the project vicinity. Localized air quality impacts would occur when emissions from vehicular traffic increase as a result of the proposed project. The primary mobilesource pollutant of local concern is CO, a direct function of vehicle idling time and, thus, of traffic flow conditions. CO transport is extremely limited; under normal meteorological conditions, CO disperses rapidly with distance from the source. However, under certain extreme meteorological conditions, CO concentrations near a congested roadway or intersection may reach unhealthful levels, affecting local sensitive receptors (e.g., residents, schoolchildren, the elderly, and hospital patients). Typically, high CO concentrations are associated with roadways or intersections operating at unacceptable levels of service or with extremely high traffic volumes. In areas with high ambient background CO concentrations, modeling is recommended to determine a project’s effect on local CO levels.

An assessment of project-related impacts on localized ambient air quality requires the projection of future ambient air quality levels be projected. Ambient CO levels monitored at the Compton and Long Beach stations (the closest stations to the project site) showed a highest recorded 1-hour concentration of 4.5 ppm (the State standard is 20 ppm) and a highest 8-hour concentration of 3.7 ppm (the State standard is 9 ppm) during the past 3 years (Table G). The highest CO concentrations would normally occur during peak traffic hours; hence, CO impacts calculated under peak traffic conditions represent a worst-case analysis.

P:\LBL2201\Air Quality\Mosaic LB AQ-GHG Report 10032022.docx (10/03/22) 63 Based on the TIA LSA prepared for the project, the proposed project would generate 278 net new AM peak-hour trips and 165 net new PM peak-hour trips. As identified in the TIA, the evaluation of the study area intersection level of service (LOS) shows that the addition of project traffic would not cause an intersection operation to deteriorate below the City’s performance threshold. 1 As the
proposed project would not substantially increase delay at nearby intersections and given the extremely low level of CO concentrations in the project area and lack of traffic impacts at any intersections, project-related vehicles are not expected to contribute significantly to result in the CO concentrations exceeding the State or federal CO standards.

Health Risk on Nearby Sensitive Receptors
Sensitive receptors are defined as people that have an increased sensitivity to air pollution or environmental contaminants. Sensitive receptor locations include schools, parks and playgrounds, day care centers, nursing homes, hospitals, and residential dwelling units. As identified above, the closest sensitive receptors to the project area include multi-family residential uses located approximately 80 feet west of the project site across The Promenade North.

Construction of the proposed project may expose surrounding sensitive receptors to airborne particulates and a small quantity of construction equipment pollutants (i.e., usually diesel-fueled vehicles and equipment). However, construction contractors would be required to implement measures to reduce or eliminate emissions by following SCAQMD rules for standard construction practices, including the use of Tier 4 construction equipment and use of low-VOC paint consistent with Downtown Plan PEIR Mitigation Measures AQ-1(c) and compliance with SCAQMD Rule 403 measures, which would substantially reduce diesel particulate matter emissions. Once operational, the proposed project would not be a source of substantial pollutant concentrations and would not generate a substantial number of truck trips that would warrant a mobile source health risk assessment. In addition, Downtown Plan PEIR Mitigation Measures AQ-4(a), AQ-4(b), and AQ-5 would further reduce exposure of sensitive receptors to operational emissions of TACs. In addition, as shown in Table P and Table Q, the project would not result in significant localized or regional emissions during project construction or operation. Therefore, with implementation of applicable Downtown Plan PEIR mitigation measures, the project would not be a source of substantial pollutant emissions, and sensitive receptors would not be exposed to substantial pollutant concentrations during project construction and operation.

Odors
During project construction, some odors may be present due to diesel exhaust. However, these odors would be temporary and limited to the construction period. The proposed project would not include any activities or operations that would generate objectionable odors and once operational, the project would not be a source of odors. In addition, Downtown Plan PEIR Mitigation Measure AQ-6 would control exposure of sensitive receptors to operational odorous emissions. Therefore, with implementation of Downtown Plan PEIR Mitigation Measure AQ-6, the proposed project would not result in other emissions (such as those leading to odors) affecting a substantial number of people.

GREENHOUSE GAS EMISSIONS IMPACTS
The following sections describe the proposed project’s construction- and operation-related GHG impacts and consistency with applicable GHG reduction plans.

Generation of Greenhouse Gas Emissions
This section describes the proposed project’s construction- and operational-related GHG emissions and contribution to global climate change.

Construction Greenhouse Gas Emissions
Demolition and construction activities associated with the proposed project would produce combustion emissions from various sources. During construction, GHGs would be emitted through the operation of construction equipment and from worker and builder supply vendor vehicles, each of which typically use fossil-based fuels to operate. The combustion of fossil-based fuels creates GHGs such as CO2, CH4, and N2O. Furthermore, CH4 is emitted during the fueling of heavy equipment. Exhaust emissions from on-site construction activities would vary daily as construction activity levels change.

Using CalEEMod, it is estimated that the project would generate 6,016.4 metric tons of CO2e during construction. When annualized over the 30-year life of the project, annual emissions would be 200.6 metric tons CO2e. Implementation of Downtown Plan PEIR Mitigation Measures GHG-1(a) and GHG1(b) would reduce construction-related GHG emissions.

Operational Greenhouse Gas Emissions
Long-term operational GHG emissions are typically associated with mobile, area, and stationary sources as well as indirect emissions from sources associated with energy consumption, waste sources, and water sources. As identified above, the proposed project would result in more daily trips than under existing conditions; therefore, the proposed project would generate new mobile source GHG emissions. Area source emissions would be associated with activities such as landscaping and maintenance on the project site, and other sources. Energy source emissions would be generated at off-site utility providers as a result of increased electricity demand generated by the project. Waste source emissions generated by the proposed project include energy generated by landfilling and other methods of disposal related to transporting and managing project generated waste. Water source emissions associated with the proposed project are generated by water supply and conveyance, water treatment, water distribution, and wastewater treatment.

GHG emissions were estimated using CalEEMod. Table R shows the calculated GHG emissions for the existing uses and the proposed project.

As discussed above, consistent with State CEQA Guidelines Section 15183.5, if a project is consistent with an adopted qualified Greenhouse Gas Reduction Strategy that meets the standards, it can be presumed that the project would not have significant GHG emission impacts. The City of Long Beach CAAP meets the requirements of State CEQA Guidelines Section 15183.5; therefore, the proposed project will be evaluated for consistency with the City’s CAAP.

As discussed above, based on the City’s LUE, the average household size is 2.92 people for owneroccupied units and 2.74 people for renter-occupied units.1 The proposed project would include renter-occupied units; therefore, development of the project site with 900 new dwelling units could house 2,466 residents. In addition, the proposed project would include 38,405 square feet of commercial uses; however, the existing site includes 197,513 square feet of existing uses with 39,224 square feet currently occupied. Therefore, this analysis assumes that the proposed project would not generate a substantial amount of new employees. As such, the total service population (employees plus population) would be 2,466 people. The proposed project would result in per service population emission of 1.5 metric tons of CO2e per year per service population, which is above the CAAP screening threshold of 1.4 metric tons of CO2e per year per service population.

Therefore, the proposed project is required to illustrate compliance with the CAAP Greenhouse Gas 1 City of Long Beach. 2019. City of Long Beach General Plan Land Use Element. December. Website:

Therefore, with implementation of Regulatory Control Measure GHG-1, the proposed project would be consistent with the City’s CAAP and would not generate greenhouse gas emissions that may have a significant effect on the environment.

Consistency with Greenhouse Gas Reduction Plans
California Air Resources Board Scoping Plan
The following discussion evaluates the proposed project according to the goals of AB 32, the AB 32 Scoping Plan, Executive Order B-30-15, SB 32, and AB 197.

AB 32 is aimed at reducing GHG emissions to 1990 levels by 2020. AB 32 requires the CARB to prepare a Scoping Plan that outlines the main State strategies for meeting the 2020 deadline and to reduce GHGs that contribute to global climate change. The AB 32 Scoping Plan has a range of GHG reduction actions, which include direct regulations, alternative compliance mechanisms, monetary and non-monetary incentives, voluntary actions, market-based mechanisms such as a cap-and-trade system, and an AB 32 implementation fee to fund the program.

Executive Order B-30-15 added the immediate target of reducing GHG emissions to 40 percent below 1990 levels by 2030. CARB released a second update to the Scoping Plan, the 2017 Scoping Plan,
1 to reflect the 2030 target set by Executive Order B-30-15 and codified by SB 32. SB 32 affirms the importance of addressing climate change by codifying into statute the GHG emissions reductions target of at least 40 percent below 1990 levels by 2030 contained in Executive Order B-30-15. SB 32 builds on AB 32 and keeps California on the path toward achieving the State’s 2050 objective of reducing emissions to 80 percent below 1990 levels. The companion bill to SB 32, AB 197, provides additional direction to the CARB related to the adoption of strategies to reduce GHG emissions.

Additional direction in AB 197 intended to provide easier public access to air emissions data that are collected by CARB was posted in December 2016.

In addition, the Draft 2022 Scoping Plan Update2 assesses progress toward the statutory 2030 target, while laying out a path to achieving carbon neutrality no later than 2045. The 2022 Scoping Plan Update focuses on outcomes needed to achieve carbon neutrality by assessing paths for clean technology, energy deployment, natural and working lands, and others, and is designed to meet the State’s long-term climate objectives and support a range of economic, environmental, energy security, environmental justice, and public health priorities.

The Scoping Plan contains GHG reduction measures that work towards reducing GHG emissions, consistent with the targets set by AB 32, Executive Order B-30-15 and codified by SB 32 and AB 197.

The measures applicable to the proposed project include energy efficiency measures, water conservation and efficiency measures, and transportation and motor vehicle measures, as discussed below.

P:\LBL2201\Air Quality\Mosaic LB AQ-GHG Report 10032022.docx (10/03/22) 68 Energy efficiency measures are intended to maximize energy efficiency building and appliance standards, pursue additional efficiency efforts including new technologies and new policy and implementation mechanisms, and pursue comparable investment in energy efficiency from all retail providers of electricity in California. In addition, these measures are designed to expand the use of green building practices to reduce the carbon footprint of California’s new and existing inventory of buildings. As discussed above, the proposed project would include high efficiency HVAC equipment and solar PV with a potential battery storage. In addition, the project would comply with CALGreen regarding energy conservation and green building standards. Therefore, the proposed project would comply with applicable energy measures.

Water conservation and efficiency measures are intended to continue efficiency programs and use cleaner energy sources to move and treat water. Increasing the efficiency of water transport and reducing water use would reduce GHG emissions. As noted above, the project would comply with CALGreen, which includes a variety of different measures, including reduction of wastewater and water use. In addition, the proposed project would be required to comply with the California Model Water Efficient Landscape Ordinance. The proposed project would also include high efficiency gas water or a heat pump water heater as a sustainability feature. In addition, the proposed project would use low-flow plumbing fixtures. Therefore, the proposed project would not conflict with any of the water conservation and efficiency measures.

The goal of transportation and motor vehicle measures is to develop regional GHG emissions reduction targets for passenger vehicles. Specific regional emission targets for transportation emissions would not directly apply to the proposed project. The second phase of Pavley standards will reduce GHG emissions from new cars by 34 percent from 2016 levels by 2025, resulting in a 3 percent decrease in average vehicle emissions for all vehicles by 2020. Vehicles traveling to the project site would comply with the Pavley II (LEV III) Advanced Clean Cars Program. In addition, the proposed project would develop a new mixed-use residential and commercial building on an infill, previously developed project site in downtown Long Beach, which would locate residents and employees near existing residential and commercial uses and alternative transportation including the Metro A Line (Blue) and other nearby public transit lines, reducing the vehicle miles traveled and the demand for travel by single-occupancy vehicles. Therefore, the proposed project would not conflict with the identified transportation and motor vehicle measures.

Therefore, the proposed project would comply with existing State regulations adopted to achieve the overall GHG emissions reduction goals identified in AB 32 and SB 32.

SCAG’S Regional Transportation Plan/Sustainable Communities Strategy SCAG’s 2020–2045 RTP/SCS was adopted September 3, 2020. SCAG’s RTP/SCS identifies that land use strategies that focus on new housing and job growth in areas served by high-quality transit and other opportunity areas would be consistent with a land use development pattern that supports and complements the proposed transportation network. The core vision in the 2020–2045 RTP/SCS is to better manage the existing transportation system through design management strategies, integrate land use decisions and technological advancements, create complete streets that are safe to all roadway users, preserve the transportation system, and expand transit and foster development in transit-oriented communities. The 2020–2045 RTP/SCS contains transportation projects to help

The forecasted development pattern, when integrated with the financially constrained transportation investments identified in the 2020–2045 RTP/SCS, would reach the regional target of reducing GHG emissions from autos and light-duty trucks by 8 percent per capita by 2020 and 19 percent by 2035 (compared to 2005 levels). The 2020–2045 RTP/SCS does not require that local General Plans, Specific Plans, or zoning be consistent with the 2020–2045 RTP/SCS but provides incentives for consistency for governments and developers.

The proposed project would include the construction of 900 residential dwelling units and 38,405 square feet of commercial uses. The project site is currently developed with commercial buildings, which would be demolished as a part of the proposed project. The new mixed-use residential and commercial building would be consistent with SCAG’s goals for new housing and job growth. In addition, although the proposed project would generate 3,509 net new average daily trips, as discussed above, the proposed project would develop a new mixed-use residential and commercial building on an infill, previously developed project site in downtown Long Beach, which would locate residents and employees near existing residential and commercial uses and alternative transportation including the Metro A Line (Blue) and other nearby public transit lines, reducing the vehicle miles traveled and the demand for travel by single-occupancy vehicles. Therefore, the proposed project would not conflict with the 2020–2045 RTP/SCS transportation strategies.

Implementing SCAG’s RTP/SCS will greatly reduce the regional GHG emissions from transportation, helping to achieve statewide emission reduction targets. The proposed project would not conflict with the stated goals of the RTP/SCS; therefore, the proposed project would not interfere with SCAG’s ability to achieve the region’s GHG reduction targets at 8 percent below 2005 per capita emissions levels by 2020 and 19 percent below 2005 per capita emissions levels by 2035, and it can be assumed that regional mobile emissions will decrease in line with the goals of the RTP/SCS.

Furthermore, the proposed project is not regionally significant per State CEQA Guidelines Section 15206, and, as such, it would not conflict with the SCAG RTP/SCS targets, since those targets were established and are applicable on a regional level.

Implementation of the proposed project is not expected to interfere with SCAG’s ability to implement the regional strategies outlined in the RTP/SCS. Therefore, the proposed project would not conflict with plans, policies, or regulations adopted for the purpose of reducing GHG emissions.

As described above, the proposed project would generally be consistent with the City’s CAAP, the Scoping Plan, and SCAG’s RTP/SCS. Therefore, the proposed project would not conflict with any applicable plan, policy, or regulation of an agency adopted for the purpose of reducing the GHG emissions.

CONCLUSION
Based on the analysis presented above, with implementation of Downtown Plan PEIR Mitigation Measures AQ-1(a) and AQ-1(c), construction of the proposed project would not result in the generation of criteria air pollutants that would exceed SCAQMD thresholds of significance. In addition, with implementation of Downtown Plan PEIR Mitigation Measure AQ-2, operation of the proposed project would not exceed SCAQMD thresholds of significance. With implementation of Mitigation Measures AQ-4(a), AQ-4(b), and AQ-6, the proposed project is not expected to produce significant emissions that would affect nearby sensitive receptors. With implementation of Downtown Plan PEIR Mitigation Measure AQ-6, the project would also not result in other emissions (such as those leading to odors) affecting a substantial number of people. With implementation of Downtown Plan PEIR Mitigation Measures GHG-1(a), GHG-1(b), GHG-2(a), and GHG-2(b) and Regulatory Control Measure GHG-1, GHG emissions released during construction and operation of the project are estimated to be lower than significance thresholds and would not be cumulatively considerable. The project would also be consistent with the City’s CAAP, the State’s GHG emissions reductions objectives embodied in AB 32, Executive Order B-30-15, SB 32, AB 197, and SCAG’s RTP/SCS. Therefore, the proposed project would not conflict with the implementation of plans adopted for the purpose of reducing GHG emissions. As such, with implementation of applicable Downtown Plan PEIR mitigation measures, the proposed project would not result in significant air quality or GHG impacts.
