HONORABLE MAYOR AND CITY COUNCIL
City of Long Beach
California
RECOMMENDATION:

Development Services Department
411 West Ocean Boulevard, 3'd Floor Long Beach, CA 90802 (562) 570-5237
H-13
Receive supporting documentation into the record, conclude the public hearing, and find that the Project is exempt from further environmental review and affirm the Planning Commission's determination (Categorical Exemption CE 21-156); and, find that the project is exempt from the California Environmental Quality Act (CEQA) pursuant to Sections 15303 (Class 3 - New Construction or Conversion of Small Structures); and, Adopt a Resolution approving a General Plan Amendment (GPA21-004) to change the Land Use Element Place Type designation of 2600 California Avenue from Open Space (OS) to Neo-lndustrial (NI). (District 5)

DISCUSSION
On November 3, 2022, the Planning Commission held a duly noticed public hearing on this project, and recommended ( 4-0, with three commissioners absent) that the City Council take the above-listed actions to approve the project (Attachment A).

The applicant proposes to construct a new 3,000-square-foot medical office building on the site, within the existing landscape area. Although the Institutional (I) Zoning District designation for the subject site allows for medical offices, the project site has a current General Plan Land Use Element PlaceType designation of Open Space (OS), which appears to have been designated as such erroneously. The existing OS PlaceType supports recreational uses such as public parks and does not allow for commercial or industrial uses, such as offices. Thus, a General Plan Amendment to change the PlaceType designation is required to allow for any development to occur on the subject private property.

Project Site
The project site is located at 2600 California Avenue on the northeast corner of California Avenue and Willow Street (Attachment 8). The 0. 72-acre (31,375-square-foot) project site is currently developed with a surface parking lot, a small open space with walking path, and associated landscaping, and can be accessed via two one-way driveways on California Avenue. The project site is currently within the I Zoning District and within the Land Use Element Open Space PlaceType. The existing parking lot, and associated landscaping was

approved through a Conditional Use Permit (CUP17-007) on June 15, 2017 for off-site parking at for a commercial building across the street at 999 East Willow Street in the City of Signal Hill. The landscaped open space area on the north side of the lot site was provided by the applicant in lieu of leaving the area undeveloped and was not required as a condition of approval.

The project site is surrounded by a mixture of open space, office, and retail uses. The project site is bounded by Sunnyside Cemetery to the east, and Willow Springs Park to the north.

Properties across California Avenue (to the west) and Willow Street (to the south) are located within the City of Signal Hill and currently developed with industrial and commercial uses.

Regional access to the project site is provided by the San Diego Freeway (1-405) and the Long Beach Freeway (1-710), which are located approximately 0.6 miles north and 1.5 miles west of the project site, respectively. Local access to the project site is provided by California Avenue and East Willow Street.

Project Proposal
The proposed project requires Site Plan Review approval to construct an approximately 3,000- square-foot single-story medical office building. For non-residential projects of less than 50,000 square feet of new Gross Floor Area, Planning Commission review is not required; therefore the Staff Site Plan Review Committee reviewed and conditionally approved this proposal on October 28, 2020. Since the General Plan Amendment, discussed above, must be approved for the development to move forward, this discussion of the Site Plan Review entitlement is presented for the record of proceedings.

The proposed building is 22'-8" in height, on the northern half of the project site (Attachment C). The project site is a long and narrow rectangular shaped lot. The proposed building would be bordered to the north and south by surface parking. Physical development would be restricted to the northern portion of the project site, including 12 parking spaces for the proposed medical office. A trash enclosure, eight feet in height, would be included on the northeastern corner of the project site. The existing southern portion of the project, which includes an existing parking lot for the property at 999 East Willow Street, will remain. The design of the proposed building meets the design requirements of the I Zoning District and the Urban Design Element (UDE) of the General Plan.

The proposed project would have a Floor Area Ratio (FAR) of 0.936, which would be consistent with the project site's proposed General Plan PlaceType designation (Neo-lndustrial) FAR (minimum of 0.5 and maximum of 1.0). The Urban Design Element specifies additional design standards for the NI PlaceType, which includes the following strategy: Policy UD 25-5:

Encourage NI Place Types to have improved walkability with on-site, sidewalk and streetscape landscaping, signage and other enhancements. The proposed building provides new landscaping along the frontage and activates the current frontage along California Avenue. The Staff Site Plan Review Committee made positive findings for approval of this Site Plan Review (Attachment D).

Existing trees on site were planted in 2020; none are significant in terms of species, history, visual appeal, or habitat. Conditions of approval will require trees that are removed along the eastern site boundary to be relocated and replanted on-site, if feasible, and replaced in kind otherwise. However, potentially nesting bird species are protected from nest disturbance by the federal Migratory Bird Treaty Act (MBT A) and the California Fish and Game Code.

Therefore, a condition of approval will require all tree removal to occur in compliance with the MBTA and be accompanied by a nesting bird survey prior to tree removal. These requirements will provide a net increase in the number of trees on the development site over existing conditions. These requirements will be enforced through conditions of approval (Attachment E).

A General Plan Amendment to the Nao-Industrial (NI) PlaceType is required to allow for the proposed land use to occur on private property. The NI PlaceType is intended for light industrial, clean manufacturing, offices and commercial uses accessory to creative business.

The NI PlaceType is used in many circumstances including as a buffer between existing industrial and residential neighborhoods. On this site, the Place Type would serve as a transition to Willow Springs Park and the Sunnyside Cemetery as well as properties across California Avenue and Willow Street, located within the City of Signal Hill and currently developed with industrial and commercial uses. While the adoption of the Land Use Element is fairly recent, the proposed General Plan Amendment is still appropriate because it corrects a City error in designating this privately owned and commercially operating parcel as Open Space (Attachment F). The Open Space designation is clearly erroneous based on the Land Use District (LUO) of the property under the 1989 General Plan which was LUO No. 9G - General Industry which was intended for light and medium industrial uses compatible with sensitive uses. As such, the proposed project would have been consistent with the 1989 LUO.

Requested Entitlements and Recommended Actions
This project requires approval of a General Plan Amendment to change the Place Type for the property from OS to NI (Attachment F). The proposed project would allow the property owner to develop a new 3,000 square-foot commercial medical building and correct a City error in designating this privately owned and commercially operated parcel. The Planning Commission recommended on November 3, 2022 that the City Council approve this General Plan Amendment. The General Plan Amendment must be adopted by a Resolution, which requires City Council action.

Public Hearing Notice
A notice of public hearing was mailed on January 3, 2023, in accordance with the requirements of Chapter 21.21 of the Long Beach Municipal Code. A notice of public hearing also was published in the Long Beach Press-Telegram on January 3, 2023, also in accordance with the requirements of Chapter 21.21. Four written comments were received via e-mail prior to the Planning Commission hearing, and one verbal public comment was received during the Planning Commission hearing on October 6, 2022. As of the time this report was written, no

additional comments have been received since the Planning Commission hearing (Attachment G).

Environmental Review
In accordance with the California Environmental Quality Act (CEQA) Section 15303, Class 3(c), this project is eligible for a CEQA Categorical Exemption for "New Construction or Conversion of Small Structure" because the Site Plan Review and General Plan Amendment is for a commercial office building in an urbanized area and would be less than 10,000 square feet. A Class 3 Categorical Exemption (CE) requires that the proposed project does not involve the use of significant amounts of hazardous substances. The proposed medical building may use small amounts of hazardous substances associated with the common medical uses but would not require a significant amount of hazardous substances. The proposed project would be consistent with the project site's current zoning designation as permitted uses in the I Zoning District include medical buildings and complexes. The project would not have any significant impacts related to traffic, noise, air quality, or water quality as discussed in the following sections. Therefore, the proposed project would be consistent with subsection (c) of Section 15303 and qualifies for a Class 3 CE (Attachment H).

The proposed project would not result in any specific or general exceptions to the use of a CE as detailed under State CEQA Guidelines Section 15332. The proposed project is an office building, in an urbanized area, not exceeding 10,000 square feet in floor area on a site zoned for such use. Additionally, the proposed project would not involve the use of significant amounts of hazardous substances where all necessary public services and facilities are available, and the surrounding area is not an environmentally sensitive area. The proposed project would not cause any impacts to traffic, noise, air quality, or water quality. The project site does not have value as habitat for endangered, rare, or threatened species. The proposed project would not result in damage to a scenic resource within a highway officially designated as a State Scenic Highway, The project site is not on any list compiled pursuant to Section 65962.5 of the Government Code. Furthermore, no unusual circumstances or potential cumulative impacts would occur that may reasonably create an environmental impact. Therefore, the proposed project is exempt from the provisions of CEQA as specified by the State CEQA Guidelines identified above.

This matter was reviewed by Deputy City Attorney Erin Weesner-McKinley on December 20, 2022 and by Revenue Management Officer Geraldine Alejo on December 16, 2022.

TIMING CONSIDERATIONS
The Development Services Department is required to transmit the Planning Commission's recommendation to the City Council within 60 days of positive action by the Planning Commission, per Section 21.25.103 of the Zoning Regulations. The Planning Commission made a positive recommendation on this project's requested actions on November 3, 2022.

DISCUSSION
The project site is located at 2600 California Avenue on the northeast corner of California Avenue and Willow Street (Attachment A – Location Map). The 0.72-acre (31,375-square foot) project site is currently developed with a surface parking lot, a small open space with walking path , and associated landscaping , and can be accessed via two one-way driveways on California Ave nue. The project site is currently within the Institutional (I) Zoning District and within the Land Use Element Open Space (OS) PlaceType. The existing parking lot, and associated landscaping was approved through a Conditional Use Permit (CUP17-007) on June 15, 2017 for off-site parking at for a commercial building across the street at 999 East Willow Street in the City of Signal Hill.

The project site is surrounded by a mixture of open space, office, and retail uses. The project site is bounded to the east by a cemetery, to the north by an urban farm, to the west by California Avenue and office uses in the City of Signal Hill , and to the south by East Willow Street and retail uses. Regional access to the project site is provided by Interstates 405 (I-405) and 710 (I-710), which are located approximately 0.6 miles n orth and 1.5 miles west of the project site, respectively. Local access to the project site is provided by California Avenue and East Willow Street.

GENERAL PLAN AMENDMENT
Attachment A

CHAIR AND PLANNING COMMISSIONERS

The project site has a current General Plan Land Use Element PlaceType designation of OS. The existing OS PlaceType supports recreational space such as public parks and does not allow for commercial or industrial uses, such as offices. Although the existing I Zoning District allows for medical offices, the land use PlaceType does not. The applicant is proposing to add a new 3,000 square foot medical office building to site , within the existing landscape area (Attachment B – Plans).

A General Plan Amendment to the Neo-Industrial (NI) PlaceType is required to allow for this development to occur on private property. The NI PlaceType is intended for light industrial, clean manufacturing, offices and commercial uses accessory to creative business. The NI PlaceType is used in many circumstances including as a buffer between existing industrial and residential neighborhoods. On this site the PlaceType would serve as a transition to Willow Springs Park to the north and the S unnyside Cemetery to the east. Properties across California Avenue (to the west) and Willow Street (to the south) are located within the City of Signal Hill and currently developed with industrial and commercial uses. While the adoption of the Land Use Element is fairly recent, the proposed General Plan Amendment is still appropriate because it corrects a City error in designating this privately owned and commercially operating parcel (Attachment C – General Plan Amendment Map).

In accordance with the General Plan, the I Zoning District is generally consistent with the NI PlaceType (Table LU -6: PlaceTypes and Zoning Districts Consistency Matrix, Page 170 of the Land Use element). The site on which the General Plan Amendment is proposed is private property. Overall, the proposed PlaceType would be harmonious with the existing land uses surrounding the site (Attachment D – Findings).

SITE PLAN REVIEW

The proposed project requires Site Plan Review approval to construct an approximately 3,000-square-foot single-story medical office building. For non-residential projects of less than 50,000 square feet of new Gross Floor Area, Planning Commission review is not required, and the Staff Site Plan Review Committee reviewed and approved this proposal on October 28, 2020. Since the General Plan Ame ndment, discussed above, must be approved by the Planning Commission and City Council, this discussion of the Site Plan Review entitlement is presented for the record of proceedings.

The proposed building is 22’-8” in height, on the northern half of the project site. The project site is a long and narrow rectangular shaped lot. The proposed building would be bordered to the north and south by surface parking. Physical development would be restricted to the northern portion of the project site , including 12 parking spaces for the proposed medical office. A trash enclosure, eight feet in height, would be included on the northeastern corner of the project site. The existing southern portion of the project, which includes an existing parking lot for the property at 999 East Willow Street, will remain. The design of the proposed building meets the design requirements of the I Zoning District.

The proposed project would have a Floor Area Ratio (FAR) of 0.936, which would be consistent with the project sit e’s proposed General Plan PlaceType designation (Neo -

The Urban Design Element specifies additional design standards for the NI PlaceType, which includes the following strategy: Policy UD 25-5: Encourage NI PlaceTypes to have improve walkability with on- site, sidewalk and streetscape landscaping, signage and other enhancements. The proposed building provides new landscaping along the frontage and parking, signage and activates the current frontage along California Avenue.

Existing trees on site were planted in 2020 ; none are significant in terms of species, history, visual appeal, or habitat. Conditions of approval will require trees to be removed along the eastern site boundary are to be relocated and replanted on -site. However, all species are protected from nest d isturbance by the federal Migratory Bird Treaty Act (MBTA) and the California Fish and Game Code. Therefore, a condition of approval will require all tree removal to occur in compliance with the MBTA and be accompanied by a nesting bird survey prior to tree removal. These requirements will provide a net increase in the number of trees on the development site over existing conditions. These requirements will be enforced through conditions of approval (Attachment E – Conditions of Approval).

PUBLIC HEARING NOTICE

A total of 543 public hearing notices were distributed on October 19, 2022, in accordance with the requirements of Chapter 21.21 of the Zoning Regulations. No public comments in response to these notices were received at the time the report was prepared.

ENVIRONMENTAL REVIEW

Pursuant to the California Environmental Quality Act (CEQA) Section 15303, Class 3(c), this project is eligible for a CEQA Categorical Exemption for “ New Construction or Conversion of Small Structure” because the Site Plan Review and General Plan Amendment is for a commercial office building in an urbanized area and would be less than 10,000 s quare feet. A Class 3 Categorical Exemption (CE) requires that the proposed project does not involve the use of significant amounts of hazardous substances. The proposed medical building may use small amounts of hazardous substances associated with the common medical uses but would not require a significant amount of hazardous substances. The proposed project would be consistent with the project site’s current zoning designation as permitted uses in the I Zoning District include medical buildings and complexes. The project would not have any significant impacts related to traffic, noise, air quality, and water quality as discussed in the following sections.

Therefore, the proposed project would be consistent with subsection (c) of Section 15303 and qualifies for a Class 3 CE (Attachment F – Categorical Exemption).

The proposed project would not cause any impacts to traffic, noise, air quality, or water

quality. The project site does not have value as habitat for endangered, rare, or threatened species. The proposed project would not result in damage to a scenic resource within a highway officially designated as a State Scenic Highway. The project site is not on any list compiled pursuant to Section 65962.5 of the Government Code.

Furthermore, no unusual circumstances or potential cumulative impacts would occur that may reasonably create an environmental impact. Therefore, the proposed project is exempt from the provisions of CEQA as specified by the State CEQA Guidelines identified above.

GENERAL PLAN AMENDMENT

FINDINGS
2600 California Avenue (APN 7212-009-017)
Application No. 2008-06 (GPA21-004)
November 3, 2022

Pursuant to California Government Code Section 65358, the City Council shall not approve a General Plan Amendment unless the following findings are made. These findings and staff analysis are presented for consideration, adoption and incorporation into the record of proceedings:

1. THE PROPOSED CHANGE WILL BENEFIT THE PUBLIC INTEREST; AND

The project site is located at 2600 California Avenue on the northeast corner of California Avenue and Willow Street. The 0.72-acre (31,375 square foot) project site is currently developed with a surface parking lot, a small open space is with walking path and associated landscaping and can be accessed via two one -way driveways on California Ave.

The project site has a current General Plan PlaceType designation of Open Space.

The proposed project would require a General Plan Amendment to change the PlaceType designation to Neo -Industrial (NI). The NI PlaceType designation permits land uses associated with offices. According to the City’s Zoning Map, the project site is currently zoned for Institutional Use (I). The proposed project would be consistent with the project sites current zoning designation as permitted uses in the Institutional Zoning District include medical buildings and complexes.

This General Plan Amendment would allow for a PlaceType that is consistent with the existing Institutional Zoning District. The proposed change would allow for the construction of a medical office, where it is not allowed with the existing PlaceType.

The General Plan Amendment would ensure consistent development standards across the site in conformance with the intent of the LUE , and will allow the economic development and use of a property that is privately owned, is unsuitably sized for a park or open space, and had no prospects of development as a park or other open space.

2. THE PROPOSED CHANGE IS CONSISTENT WITH THE ZONING
DESIGNATIONS.

Although the existing Institutional District allows for medical offices, the land use PlaceType does not. The existing General Plan, Open Space PlaceType supports recreational space such as public parks and does not allow for commercial uses, such as offices. A General Plan Amendment is needed for the site to allow for development to occur on private property. The Institutional zone is consistent with the Neo Industrial PlaceType (Table LU -6: PlaceTypes and Zoning Districts General Plan Amendment Findings

Application No. 2008-06 (GPA21-004; SPR20-021)
November 3, 2022

Consistency Matrix, Page 170 of the Land Use element). The Neo -Industrial PlaceType aligns with the surrounding uses abutting the site to the west.

SITE PLAN REVIEW

FINDINGS
2600 California Avenue (APN 7212-009-017)
Application No. 2008-06 (SPR20-021)
November 3, 2022

Pursuant to Section 21.25.506 of the Zoning Ordinance, the Site Plan Review Committee or the Planning Commission shall not approve a Site Plan Review unless the following findings are made. These findings and staff analysis are presented for consideration, adoption, and incorporation into the record of proceedings.

1. THE DESIGN IS HARMONIOUS, CONSISTENT, AND COMPLETE WITHIN ITSELF

AND IS COMPATIBLE IN DESIGN, CHARAC TER, AND SCALE WITH

NEIGHBORING STRUCTURES AND THE COMMUNITY IN WHICH IT IS LOCATED;
The proposed project would construct an approximately 3,000-squar-foot single- story medical commercial building located on the northern half of the project site. The project site is a long and narrow rectangular shape d lot. The propose building would be bordered to the north and south by surface parking. Physical development would be restricted to the northern portion of the project site. The southern portion of the project site includes an existing parking lot for the property at 999 East Willow Street.

A trash enclosure, eight feet in height, would be included on the northeastern corner of the project site. The trash enclosure would include a concrete tilt up roof along with swinging gates and a roof.

The Institutional zoning district has three main criteria for building design, treatment and finish. First, all side of a building visible from a public street or adjoining, abutting or adjacent to a residential district, shall be designed, treated and finished in a manner compatible with the residential area and with other visible sides of the building. The building is not located adj acent to a residential district, but it provides a consistent material throughout, described below. Second, not less than ten percent (10%) of a building wall shall be treated and finished with a material other than stucco or c pement block, painted or unpainted. As such, the design of the proposed building will primarily be constructed out of concrete masonry unit (CMU) blocks with silver, white, gray and black. Additionally, the building will have an overhang at the front face of the building which provides a break on the building mass. Overall, the design meets the design requirements of the Institutional Zoning District. Lastly, all roof areas not visible from the public right-of-way shall be provided with

2. THE DESIGN CONFORMS TO ANY APPLICABLE SPECIAL DESIGN

GUIDELINES ADOPTED BY THE PLANNING COMMISSION OR SPECIFIC PLAN REQUIREMENTS, SUCH AS THE DESIGN GUIDELINES FOR R-3 AND R-4 MULTI-

FAMILY DEVELOPMENT, THE DOWNTOWN DESIGN GUIDELINES, PD
GUIDELINES, OR THE GENERAL PLAN;
General Plan Land Use Element: The project site has a current General Plan PlaceType designation of Open Space. The proposed project would require a General Plan Amendment to change the PlaceType designation to Neo-Industrial (NI). The NI PlaceType designation permits land uses associat ed with offices , the project site is currently zoned for Institutional Use (I). The proposed project would be consistent with the project sites current zoning designation as permitted uses in the Institutional Zoning District include medical buildings and complexes.

The proposed project would have a Floor Area Ratio (FAR) of 0.936, which would be consistent with the project site’s proposed General Plan PlaceType designation (Neo- Industrial) FAR (minimum of 0.5 and maximum of 1.0).

General Plan Urban Design Element: The Urban Design Element specifies additional design standards for the NSC-LNeo-Industrial PlaceType, which includes the following strategy:
• Policy UD 2 5-5: Encourage Neo -Industrial PlaceTypes to have improve d walkability with on -site, sidewalk and streetscape landscaping , signage and other enhancements.
o The proposed building provides new landscaping along the frontage and parking, signage and activates the current frontage along California Avenue.

No other special design guidelines adopted by Planning Commission, Planned Development District, or Specific Plan applies.

3. THE DESIGN WILL NOT REMOVE SIGNIFICANT MATURE TREES OR STREET TREES, UNLESS NO ALTERNATIVE IS POSSIBLE;
Existing trees on site were planted in 2020, none are significant in terms of species, history, visual appeal, or habitat. Conditions of approval will require trees to be removed along the eastern site boundary to be relocated and replanted on-site.

However, all species are protected from nest disturbance by the federal Migratory Bird Treaty Act (MBTA) and the California Fish and Game Code. Therefore, a condition of approval will require all tree removal to occur in compliance with the MBTA and be accompanied by a nesting bird survey prior to tree removal.

These requirements will provide a net increase in the number of trees on the development site over existing conditions. These requirements will be enforced through conditions of approval (see conditions in the project file).

4. THERE IS AN E SSENTIAL NEXUS BETWEEN THE PUBLIC IMPROVEMENT

REQUIREMENTS ESTABLISHED BY THIS ORDINANCE AND THE LIKELY IMPACTS OF THE PROPOSED DEVELOPMENT; AND
The Applicant is required to make public improvements per Chapter 21.47 and per the Technical Advisory Committee (TAC) comments submitted to the Planning Bureau by the Public Works Department, including without limitation the following:
• The Developer shall dedicate to the City of Signal Hill, and improve an approximately 10-foot by 10-foot corner cut-off for ADA curb ramp purposes at the corner of California Avenue and Willow Street adjacent to the development site, to the satisfaction of the Director of Public Works. A complete application along with all required items plus filing fee shall be submitted for review and processing.
• Developer shall be responsible for resolving all matters of easement(s) and/ or utilities encroachment to the satisfaction of the interested agency, City Department, and the Director of Public Works.
• Backflow preventer must be installed on private property and a Grant of Easement to the City must be applied for and processed. • The Developer shall demolish the existing sidewalk and curb ramp located on the corner of California Avenue and Willow Street adjacent to the project site, and construct a new ADA compliant curb ramp to the satisfaction of the Director of Public Works. Sidewalk improvements shall be constructed with Portland cement concrete.
• The Developer shall submit any off -site improvement plans for review and approval to the City of Signal Hill. Any Conditions of Approval imposed on the project by the City of Signal Hill shall be incorporated by reference.

There is an essential nexus between all the above -required improvements and the likely impacts of the proposed project. As such, the City of Long Beach Department of Public Works has communicated with the City of Signal Hill to ensure the new building will comply with the public improvement requirements of both the City of Long Beach and the City of Signal Hill.

a. Retain a Native American Monitor Prior to Commencement of Ground- Disturbing Activities
1) The project applicant/lead agency shall retain a Native American Monitor from or approved by the Gabrieleño Band of Mission Indians – Kizh Nation.

The monitor shall be retained prior to the commencement of any “ground - disturbing activity” for the subject project at all project locations (i.e., both on-site and any off -site locations that are included in the pr oject 2600 California Avenue (APN 7212-009-017)
Application No. 2008-06 (GPA21-004; SPR20-021)

description/definition and/or required in connection with the project, such as public improvement work). “Ground-disturbing activity” shall include, but is not limited to, demolition, pavement removal, potholing, auguring, grubbing, tree removal, boring, grading, excavation, drilling, and trenching. 2) A copy of the executed monitoring agreement shall be submitted to the Planning Bureau prior to the earlier of the commencement of any ground - disturbing activity, or the issuance of any permit necessary to commence a ground-disturbing activity.
3) The monitor will complete daily monitoring logs that will provide descriptions of the relevant ground -disturbing activities, the type of construction activities performed, locations of ground- disturbing activities, soil types, cultural -related materials, and any other facts, conditions, materials, or discoveries of significance to the Tribe. Monitor logs will identify and describe any discovered TCRs, including but not limited to, Native American cultural and historical artifacts, remains, places of significance, etc., (collectively, tribal cultural resources, or “TCR”), as well as any discovered Native American (ancestral) human remains and burial goods. Copies of monitor logs will be provided to the project applicant/lead agency upon written request to the Tribe.
4) On-site tribal monitoring shall conclude upon the latter of the following (1) written confirmation to the Kizh from a designated point of contact for the project applicant/lead agency that all ground -disturbing activities and phases that may involve ground- disturbing activities on the project site or in connection with the project are complete; or (2) a determination and written notification by the Kizh to the project applicant/lead agency that no future, planned construction activity and/or development/construction phase at the project site possesses the potential to impact Kizh TCRs. 5) Upon discovery of any TCRs, all construction activities in the immediate vicinity of the discovery shall cease (i.e., not less t han the surrounding 50 feet) and shall not resume until the discovered TCR has been fully assessed by the Kizh monitor and/or Kizh archaeologist. The Kizh will recover and retain all discovered TCRs in the form and/or manner the Tribe deems appropriate, in the Tribe’s sole discretion, and for any purpose the Tribe deems appropriate, including for educational, cultural and/or historic purposes.
b. Unanticipated Discovery of Human Remains and Associated Funerary Objects
1) Native American human remains are defined in PRC 5097.98 (d)(1) as an inhumation or cremation, and in any state of decomposition or skeletal completeness. Funerary objects, called associated grave goods in Public Resources Code Section 5097.98, are also to be treated according to this statute.
2) If Native American human remains and/or grave goods discovered or recognized on the project site, then all construction activities shall immediately cease. Health and Safety Code Section 7050.5 dictates that any discoveries of human skeletal material shall be immediately reported to the County Coroner and all ground-disturbing activities shall immediately halt and shall remain halted until the coroner has determined the nature of 2600 California Avenue (APN 7212-009-017)
Application No. 2008-06 (GPA21-004; SPR20-021)
November 3, 2022

Page 3 of 11 ends

the remains. If the coroner recognizes the human remains to be those of a Native American or has reason to believe they are Native American, he or she shall contact, by telephone within 24 hours, the Native American Heritage Commission, and Public Resources Code Section 5097.98 shall be followed.
3) Human remains and grave/burial goods shall be treated alike per California Public Resources Code section 5097.98(d)(1) and (2).
4) Construction activities may resume in other parts of the project site at a minimum of 200 feet away from discovered human remains and/or burial goods, if the Kizh determines in its sole discretion that resuming construction activities at that distance is acceptable and provides the project manager express consent of that determination (along with any other mitigation measures the Kizh monitor and/or archaeologist deems necessary). (CEQA Guidelines Section 15064.5(f).)
5) Preservation in place (i.e., avoidance) is the preferred manner of treatment for discovered human remains and/or burial goods. Any historic archaeological material that is not Native American in origin (non- TCR) shall be curated at a public, non-profit institution with a research interest in the materials, such as the Natural History Museum of Los Angeles County or the Fowler Museum, if such an institution agrees to accept the material.

If no institution accepts the archaeological material, it shall be offered to a local school or historical society in the area for educational purposes. 6) Any discovery of human remains/burial goods shall be kept confidential to prevent further disturbance.
c. Procedures for Burials and Funerary Remains:
1) As the Most Likely Descendant (“MLD”), the Koo- nas-gna Burial Policy shall be implemented. To the Tribe, the term “human remains” encompasses more than human bones. In ancient as well as historic times, Tribal Traditions included, but were not limited to, the preparation of the soil for burial, the burial of funerary objects with the deceased, and the ceremonial burning of human remains.
2) If the discovery of human remains includes four or more burials, the discovery location shall be treated as a cemetery and a separate treatment plan shall be created.
3) The prepared soil and cremation soils are to be treated in the same manner as bone fragments that remain intact. Associated funerary objects are objects that, as part of the death rite or ceremony of a culture, are reasonably believed to have been placed with individual human remains either at the time of death or later; other items made exclusively for burial purposes or to contain human remains can also be considered as associated funerary objects. Cremations will either be removed in bulk or by means as necessary to ensure complete recovery of all sacred materials.
4) In the case where discovered human remains cannot be fully documented and recovered on the same day, the remains will be covered with muslin cloth and a steel plate that can be moved by heavy equipment placed over the excavation opening to protect the remains. If this type of steel plate is 2600 California Avenue (APN 7212-009-017)
Application No. 2008-06 (GPA21-004; SPR20-021)

not available, a 24-hour guard should be posted outside of working hours.

The Tribe will make every effort to recommend diverting the project and keeping the remains in situ and protected. If the project cannot be diverted, it may be determined that burials will be removed.
5) In the event preservation in place is not possible despite good faith efforts by the project applicant/developer and/or landowner, before ground - disturbing activities may resume on the project site, the landowner shall arrange a designated site location within the footprint of the project for the respectful reburial of the human remains and/or ceremonial objects. 6) Each occurrence of human remains and associated funerary objects will be stored using opaque cloth bags. All human remains, funerary objects, sacred objects and objects of cultural patrimony will be removed t o a secure container on site if possible. These items should be retained and reburied within six months of recovery. The site of reburial/repatriation shall be on the project site but at a location agreed upon between the Tribe and the landowner at a site to be protected in perpetuity. There shall be no publicity regarding any cultural materials recovered.
7) The Tribe will work closely with the project’s qualified archaeologist to ensure that the excavation is treated carefully, ethically and respectfully. If data recovery is approved by the Tribe, documentation shall be prepared and shall include (at a minimum) detailed descriptive notes and sketches.

All data recovery data recovery -related forms of documentation shall be approved in advance by the Tribe. If any data recovery is performed, once complete, a final report shall be submitted to the Tribe and the NAHC. The Tribe does NOT authorize any scientific study or the utilization of any invasive and/or destructive diagnostics on human remains.

Standard Conditions – Plans, Permits, and Construction:

8. If initial construction activities take place during the bird nesting season (January through September), a nesting bird survey should be performed by a qualified biologist within three days of such activities to determine the presence/absence, location, and status of any active nests on -site or within 100 feet of the site. The findings of the survey should be summarized in a report to be submitted to the City of Long Beach prior to undertaking construction activities at the site.
a. If nesting birds are found on- site, a construction buffer of 500 feet for nesting raptors or threatened or endangered species and 100 feet of all other nesting birds should be implemented around the active nests and demarcated with fencing or flagging. Nests should be monitored at a minimum of once per week by the qualified biologist until it has been determined that the nest is no longer being used by either the young or adults. No ground disturbance should occur within this buffer until the qualified biologist confirms that the breeding/nesting is completed, and all the young have fledged. If project activities must occur within the buffer, they should be conducted at the discretion of the qualified biologist. b. If no nesting birds are observed during pre-construction surveys, no further actions would be necessary.

Re: Agenda Item I, Nov. 3, 2022 agenda
Recommendation to recommend that the City Council accept Categorical Exemption CE21-156; and Recommend that the City Council approve a General Plan Amendment (GPA21-004), to change the PlaceType designation of 2600 California Avenue from Open Space (OS) to NeoIndustrial (NI).

I urge a No vote for both of these motions.

The staff report states: “The project site is located at 2600 California Avenue on the northeast corner of California Avenue and Willow Street (Attachment A – Location Map). The 0.72-acre (31,375-square foot) project site is currently developed with a surface parking lot, a small open space with walking path, and associated landscaping, and can be accessed via two one-way driveways on California Avenue. The project site is currently within the Institutional (I) Zoning District and within the Land Use Element Open Space (OS) PlaceType. The existing parking lot, and associated landscaping was approved through a Conditional Use Permit (CUP17-007) on June 15, 2017 for off-site parking at for a commercial building across the street at 999 East Willow Street in the City of Signal Hill. The project site is surrounded by a mixture of open space, office, and retail uses. The project site is bounded to the east by a cemetery, to the north by an urban farm, (and Willow Springs Park--A.C.)to the west by California Avenue and office uses in the City of Signal Hill, and to the south by East Willow Street and retail uses.

While the adoption of the Land Use Element is fairly recent, the proposed General Plan Amendment is still appropriate because it corrects a City error in designating this privately owned and commercially operating parcel.”
My comments:

This site is currently zoned Institutional and is Open Space in the Land Use Element. As the staff report states, Open Space Place Type is for Public Parks, not commercial or industrial uses. Zoning should not be changed because a land owner wants a non-conforming use.

This land already has walking paths and landscaping. The plans call for cutting down mature trees and digging up possible Native American burial sites, with no CEQA evaluation. The site should remain as Open Space. At the very least, if the Place Type and Zoning are changed, an Environmental Impact Report must be required for any development.

DATE: September 29, 2022
TO: Alexis Oropeza, Current Planning Officer
FROM: Ashley Davis, Principal
SUBJECT: Class 3 Categorical Exemption for the Proposed Medical Building at 2600 California Avenue in the City of Long Beach, Los Angeles County, California LSA is pleased to submit this memorandum in consideration of a Class 3 Categorical Exemption for the proposed Medical Building at 2600 California Avenue (project) in the City of Long Beach, Los Angeles County, California.

PROJECT DESCRIPTION
Existing Project Site
As shown in Figure 1 (all figures are provided in Attachment A), the project site is located at 2600 California Avenue in City of Long Beach. The 0.72-acre (31,375 square foot [sf]) project site is long and rectangular shaped located on the northeast corner of California Avenue and East Willow Street The project site consists of Assessor’s Parcel Number (APN ) 7212-009-017. The project site is currently developed with a surface parking lot, a small open space area with walking path, and associated landscaping. The project site is generally flat in elevation. In the project site’s existing condition, vehicular access is provided via two one-way driveways on California Avenue.

The project site is surrounded by a mixture of open space, office, and retail uses. The project site is bounded to the east by a cemetery, to the north by an urban farm, to the west by California Avenue and office uses, and to the south by East Willow Street and retail uses. Regional access to the project site is provided by Interstates 405 (I-405) and 710 (I-710), which are located approximately 0.6 miles north and 1.5 miles west of the project site, respectively. Local access to the project site is provided by California Avenue and East Willow Street.

Proposed Project
The proposed project would construct a n approximately 3,000 sf single story medical commercial building located on the northern half of the project site. Figure 2, Conceptual Site Plan, provides an overview of the proposed site plan, including the location of the proposed building, parking areas, trash enclosure, transformer, and associated landscaping. The project site is a long a nd narrow rectangular shap e. The propose building would be bordered to the north and south by surface parking. As shown in Figure 3, physical development would be restricted to the northern portion of the project site. The southern portion of the project site includes existing par king and associated landscaping. This portion of the project site would not include physical development besides the placement of the proposed transformer and restriping of existing parking spaces . The proposed transformer would be located immediately south of the building’s exterior on the southeast corner.

Attachment H

9/29/22 (P:\CLB1904.39 Medical Building CE\CE\2600 California Ave Medical Building Final CE 9_29.docx) 2 A trash enclosure, 8 ft in height, would be included on the northeastern corner of the project site. The trash enclosure would include a concrete tilt up roof along with swinging gates and a roof.

Zoning and General Plan Land Use Designations
The project site has a current General Plan Pla ceType designation of Open Space. The proposed project would require a General Plan Amendment to change the PlaceType designation to Neo - Industrial (NI). The NI PlaceType designation permits land uses associated with offices . According to the City’s Zoning Map, the project site is currently zoned for Institutional Use (I). The proposed project would be consistent with the project sites current zoning designation as permitted uses in the Institutional Zoning District include medical buildings and complexes.

The proposed project would have a Floor Area Ratio (FAR) of .936, which would be consistent with the project site’s proposed General Plan PlaceType designation (Neo-Industrial) FAR (minimum of 0.5 and maximum of 1.0).

Parking
The proposed project would include 61 parking spaces in total, 49 of which are maintained as off-site parking for the office building located at 999 E. Willow Street, which is located in the City of Signal Hill across California Avenue. Of the 12 new spaces required for the proposed project, the following would be supplied: one van-accessible space, one electric vehicle (EV) van-accessible space, two EV charging station spaces, and two carpool/vanpool spaces. Of the 49 existing spaces 13 would be EV designated spaces, and 4 would be carpool/vanpool spaces. The project site is divided into the northern portion that includes proposed physical development and the southern portion that would not include physical development. The southern portion of the project site includes existing parking, lighting, and landscaping that would not be physically altered. The only improvements applied to the existing parking would be the designation of 13 existing parking spaces to EV capable spaces and the designation of 4 existing spaces to “vanpool or carpool”. The proposed project would include 4 bicycle parking stalls.

Building Design
The proposed building would have a total floor area of approximately 3,000 sf and would have a building footprint of 9.64% of the total project site (31,275 sf). The overall height of the medical office building is proposed to a maximum of 24 ft 8 inches. The building entrance would be provided at the northwest corner and would be ADA accessible. The proposed building windows would be a dual pane storefront system, with 65% visible light transmittance.

Lighting
The proposed project includes minimal parking lot lighting as required by the Chapter 21 Section

41.259 of the Zoning Regulations (Title 21 of the Long Beach Municipal Code). One proposed lighting pole would be included in the parking lot north of the proposed building along the eastern project site boundary. This lighting fixture would include glare shields to direct light downwards and avoid light intrusion onto adjacent properties. There are currently 11 existing p arking lot lighting poles in the parking area south of the proposed building which would be kept in place by the proposed project.

Lighting fixtures would be included at all exits and entrances.

9/29/22 (P:\CLB1904.39 Medical Building CE\CE\2600 California Ave Medical Building Final CE 9_29.docx) 3 Landscaping
The landscaping for the proposed project would include approximately 20 percent of the total project site. Proposed plant materials would be low to moderate water plantings and would match the existing landscaping included in the existing parking area in the southern portion of t he project site.

The proposed project would include planting of 5 new trees and 41 shrubs. Approximately 30 percent of the landscaping would be within a medium water zone and 70 percent would be within a low water zone. The proposed project would be servic ed with drip irrigation in order to reduce runoff. In accordance with the Chapter 21.42 of the Zoning Regulations, the proposed landscaping and irrigation for the proposed project would incorporate the Best Management Practices within the Model Water Efficient Landscape Ordinance and the Maximum Allowable Water Allowance.

Site Access
Vehicular access would be provided by two driveways on the west side of the project site. The project site would also include an exit-only driveway onto California Avenue, with a right-turn only restriction.

Infrastructure Improvements
The proposed project would use existing electricity, water, and sewer lines and connections in California Avenue. As part of the project, new electricity, water, and sewer infrastructure would be constructed within the project site to connect the proposed buildings to the existing main lines. The proposed project includes a proposed 6 -inch sewer line connection to the main 15 -inch sewer line located in California Avenue. Additionally, the proposed project would include a 2-inch domestic service connection to the domestic water supply located in California Avenue. A 12 ft -wide Los Angeles County Flood Control District easement is located along the northern-most boundary of the project site.

Construction and Grading
Development of the proposed project would require excavation and grading of the site; delivery of materials and personnel; construction of the building area and proposed parking lot; and landscaping of the project site. Construction of the proposed project is anticipated to commence in 2023 and take approximately 6 months. It is anticipated that an average of 8 construction workers onsite per day.

Based on the preliminary grading plans, approximately 350 cubic yards would be export ed from the project site. Demolition, grading, and building activities would involve the use of standard construction equipment such as scissor lifts, grading equipment, water truck, street sweeper, large forklift, standard trade trucks.

Discretionary Actions, Permits, and Other Approvals
In accordance with Sections 15050 and 15367 of the State CEQA Guidelines, the City is the designated Lead Agency for the proposed project and has principal authority and jurisdiction for CEQA actions and project approval. Responsible Agencies are those agencies that have jurisdiction or authority over one or more aspects associated with the development of a proposed project and/or mitigation.

Trustee Agencies are State agencies that have jurisdiction by law over natural resources affected by a proposed project.

The discretionary actions to be considered by the City as a part of the proposed project include:

CALIFORNIA ENVIRONMENTAL QUALITY ACT
Class 3 Categorical Exemption: New Construction or Conversion of Small Structures Under State CEQA Guidelines Section 15303, a Class 3 CE is applicable to projects that include construction and location of limited numbers of new, small facilities or structures; installation of small new equipment and facilities in small structures; and the conversion of existing small structures from one use to another where only minor modifications are made in the exterior of the structure. The numbers of structures described in this section are the maximum allowable on any legal parcel but cannot involve the use of significant amounts of hazardous substances. A Class 3 CE allows for the construction and operation of projects including but not limited to the following:
a. One single -family residence, or a second dwelling unit in a residential zone. In urbanized areas, up to three single -family residences may be constructed or converted under this exemption.
b. A duplex or similar multi- family residential structure totaling no more than four dwelling units. In urbanized areas, this exemption applies to apartments, dup lexes, and similar structures designed for not more than six dwelling units. c. A store, motel, office, restaurant, or similar structure not involving the use of significant amounts of hazardous substances, and not exceeding 2500 sf in floor area. In urbanized areas, the exemption also applies to up to four such commercial buildings not exceeding 10,000 sf in floor area on sites zoned for such use if not involving the use of significant amounts of hazardous substances where all necessary public services and facilities are available, and the surrounding area is not environmentally sensitive.

QUALIFICATION OF THE PROPOSED PROJECT
As the proposed project does not include any residential uses, accessory residential structures, or an accessory steam sterilization unit, subsections (a), (b), (d), (e), and (f) are not applicable to the proposed project. Under subsection (c) of Section 15303, the proposed project qualifies for a Class 3

9/29/22 (P:\CLB1904.39 Medical Building CE\CE\2600 California Ave Medical Building Final CE 9_29.docx) 5 CE because it is a commercial office building in an urbanized area and would be less than 10,000 sf. A Class 3 CE requires that the proposed project does not involve the use of significant amounts of hazardous substances. The proposed medical building may use small amounts of h azardous substances associated with the common medical uses but would not require a significant amount of hazardous substances. The proposed project would be consistent with the project site’s current zoning designation as permitted uses in the Institutional Zoning District include medical buildings and complexes. The project would not have any significant impacts related to traffic, noise, air quality, and water quality as discussed in the following sections. Therefore, the proposed project would be consistent with subsection (c) of Section 15303 and qualifies for a Class 3 CE.

Traffic
A Traffic Analysis for Medical Building Project at 2600 California Avenue (LSA, August 2022) (Attachment B) was prepared to identify the trip generation and potential vehicle miles traveled (VMT) impacts associated with the proposed project.

Trip Generation
The proposed project would not alter regional traffic patterns because existing surface parking spaces are being retained. New traffic generated by the proposed project was calculated using the Institute of Transportation Engineers’ (ITE) Trip Generation Manual, 11 th Edition.1 Table A, below, presents the
trip generation summary for the project. As Table A indicates, the proposed project is anticipated to generate 108 average daily trips (ADT), including 9 trips in the a.m. peak hour and 12 trips in the p.m. peak hour.

The City of Long Beach Traffic Impact Analysis Guidelines (June 2020) establish thresholds for analysis of a project’s vehicle level of service impacts. A project’s study area is determined by the facilities at which the project adds 50 or more peak-hour trips. Below this threshold, a project’s traffic impact on intersection performance is expected to be below the significance threshold. Based on the trip generation shown in Table A, the project would generate 12 or fewer trips per hour, which is well below the study area threshold. Therefore, the project would have a less than significant impact on vehicle level of service.

9/29/22 (P:\CLB1904.39 Medical Building CE\CE\2600 California Ave Medical Building Final CE 9_29.docx) 6 Vehicle Miles Traveled Analysis
As a result of Senate Bill (SB) 743, the California Office of Administrative Law cleared the revised State CEQA Guidelines for use on December 28, 2018. Concurrent with the revised State CEQA Guidelines, the Governor’s Office of Planning and Research released the Technical Advisory on Evaluating Transportation Impacts in CEQA (December 2018). As currently adopted, the State CEQA Guidelines indicate that VMT generated by a land use project is general ly the most appropriate measure of transportation impacts. The City of Long Beach Traffic Impact Analysis Guidelines (June 2020) establish screening thresholds, analysis methodology, and significance thresholds for VMT analyses in Long Beach.

Both the City guidelines and the State’s Technical Advisory provide screening thresholds for small projects. The City guidelines screen out projects generating fewer than 500 daily trips as the greenhouse gas emissions resulting from this level of vehicle traffic would be less than comparable to greenhouse gas emissions thresholds. The State’s Technical Advisory recommends that development with fewer than 110 daily trips be presumed to have a less than significant impact because projects with this level of traffic are likely to fit the criteria established for a categorical exemption for CEQA analysis.

Based on the trip generation shown in Table A, the project would generate 108 daily trips, which is below the screening thresholds described above. Therefore, the project is presumed to have a less than significant impact on VMT.

Noise
The Noise and Vibration Impact Analysis for the Medical Office Building Project at 2600 California Avenue (Noise and Vibration Impact Analysis) (LSA, August 2022) prepared for the proposed project is provided in Attachment C.

Construction Noise Impacts
Two types of short- term noise impacts would occur during project construction, including:
(1) equipment delivery and construction worker commutes; and (2) project construction activities.

The first type of short-term construction noise would result from transport of construction equipment and materials to the project site and construction worker commutes. These transportation activities would incrementally raise noise levels on access roads leading to the site. It is expected that larger trucks used in equipment delivery would generate higher noise impacts than trucks associated with worker commutes. The single-event noise from equipment trucks passing at a distance of 50 ft from a sensitive noise receptor would reach a maximum level of 84 dBA L max. However, the pieces of heavy
equipment for grading and construction activities would be moved on site only one time and would remain on site for the duration of each construction phase. This one -time trip, when heavy construction equipment is moved on and off site, would not significantly add to the traffic noise experienced over a 24-hour period in the project vicinity. The total number of daily vehicle trips would be minimal when compared to existing traffic volumes on the affected streets, and the long -term noise level change associated with these trips would not be perceptible. Therefore, equipment transport noise and construction-related worker commute impacts would be short- term and would not result in a significant off-site noise impact.

9/29/22 (P:\CLB1904.39 Medical Building CE\CE\2600 California Ave Medical Building Final CE 9_29.docx) 7 The second type of short- term noise impact is related to noise generated during site preparation, grading, building construction, architectural coating, and paving on the project site. Construction is undertaken in discrete steps, each of which has its own mix of equipment, and consequently its own noise characteristics. These various sequential phases would change the character of the noise generated on the project site. Therefore, the noise levels vary as construction progresses. Despite the variety in the type and size of construction equipment, similarities in the dominant noise sources and patterns of operation allow constructio n-related noise ranges to be categorized by work phase.

Table B lists the maximum noise levels recommended for noise impact assessments for typical construction equipment based on a distance of 50 ft between the equipment and a noise receptor.

Typical operating cycles for these types of construction equipment may involve 1 to 2 minutes of full power operation followed by 3 to 4 minutes at lower power settings.

Note: Noise levels reported in this table are rounded to the nearest whole number. 1 The usage factor is the percentage of time during a construction noise operation that a piece of construction equipment is operating at full power.
2 The maximum noise levels were developed based on Specification 721.560 from the Central Artery/Tunnel (CA/T) program to be consistent with the City of Boston’s Noise Code for the “Big Dig” project.

CA/T = Central Artery/Tunnel
FHWA = Federal Highway Administration
ft = foot/feet

The project construction composite noise levels at a distance of 50 ft would range from 74 dBA Leq to 85 dBA Leq based on a 40 percent usage factor, with the highest noise levels occurring during the grading phase.

9/29/22 (P:\CLB1904.39 Medical Building CE\CE\2600 California Ave Medical Building Final CE 9_29.docx) 8 on the average distance of activities to the surrounding receptors that would be approximately 185 ft from the property line of the existing Long Beach Islamic Center to the northwest and approximately 30 ft from the property line of the existing sensitive Sunnyside Cemetery to the east. At the estimated distances, construction noise levels experienced would be 73. 0 dBA and 78.0 dBA for the Isl amic center and the cemetery, respectively.

Although the project construction noise would be higher than the ambient noise in the project vicinity, it would cease to occur once the project construction is completed . The proposed project would comply with t he requirements of the City of Long Beach Noise Ordinance, which states that construction activities shall only occur between the hours of 7:00 a.m. to 7:00 p.m., Monday through Friday and federal holidays; or between 9:00 a.m. to 6:00 p.m. on Saturdays. C onstruction shall not occur on Sundays. Additionally, construction noise levels on average are expected to be below the FTA’s recommended 90 dBA L
eq standard. Compliance with the Noise Ordinance would ensure that construction noise does not disturb surroun ding receptors during hours when ambient noise levels are likely to be lower (i.e., at night). In addition, the proposed project would implement several best practices for reducing construction noise, including, but not limited to, maximizing the distance between noise sources and sensitive receptors during construction activities, and equipping construction equipment with properly operating and maintained noise mufflers . In conclusion, construction noise would be reduced to a less than significant level with compliance with the Title 21 of the Long Beach Municipal Code. allowable construction hours, and incorporation of the recommended best business practices.

Construction Vibration Impacts
Ground-borne noise and vibration from construction activity would be mostly low to moderate. While there is currently limited information regarding vibration source levels, to provide a comparison of vibration levels expected for a project of this size, a small bulldozer and loaded truck, as shown in Table C would generate approximately 0.003 in/sec in PPV and 0.076 in/sec in PPV , respectively, of ground-borne vibration when measured at 25 ft. Table D further shows the PPV values from other construction vibration sources at 25 ft from construction vibration sources for comparison purposes.

FTA = Federal Transit Administration
in/sec = inches per second
PPV = peak particle velocity

The distance to the nearest buildings for vibration impact analysis is measured between the nearest off-site buildings and the project boundary (assuming the construction equipment would be used at or near the project boundary) because vibration impacts occur at the buildings.

As shown in Table D, vibration levels exceeding 0.5 in/sec in PPV would result in building damage to structures constructed of non-engineered timber and masonry buildings. The closest receptor to the proposed construction activities is the existing Long Beach Islamic Center at 995 E 27 th Street, Signal Hill, which is located 160 ft northwest of the boundary of the proposed project.

Utilizing the equations above, it is expected that vibration levels generated by dump trucks and other large equipment that would be as close as approximately 160 ft would approach 0.005 in/sec in PPV, which would be below the 0.2 PPV in/sec threshold. Therefore, no construction vibration impacts would occur. No vibration reduction measures are required.

Long-Term Traffic Noise Impacts
In order to assess the potential traffic impacts related to the proposed project, LSA prepared the Traffic Analysis for Medical Building Project at 2600 California Avenue in Long Beach, California (2022).

Based on the traffic analysis results, it was determined that a net additional 108 average daily trips (ADT) would be generated by the proposed project. The existing traffic volume on the adjacent segment of East Willow Street from Atlantic Avenue to Cherry Avenue is 29,350 (Southern California Association of Governments [SCAG] 2017). With an increase of 108 ADT, the noise level increase would be less than 0.1 dBA CNEL. A noise level increase of less than 1 dBA would not be perceptible to the human ear ; therefore, the traffic noise increase along East Willow Street resulting from the project would be less than significant.

Long-Term Stationary Noise Impacts
The proposed project would include mechanical equipment re lated to heating, ventilation, and air conditioning (HVAC) equipment which could operate 24 hours per day. Rooftop HVAC would generate noise levels of 66.6 dBA L
eq at 5 ft per HVAC unit based on previous measurements conducted by LSA.

Based on the site plan, two HVAC units will be installed and would generate noise levels of 69.6 dBA Leq at 5 ft. Table E presents the noise levels from HVAC equipment at the nearest noise- sensitive location.

ft = foot/feet
HVAC = heating, ventilation, and air conditioning
Leq = equivalent continuous sound level

With two HVAC units installed, noise generated from on-site HVAC equipment would potentially reach up to 38.2 dBA Leq at the Long Beach Islamic Center, which would not exceed the City of Signal Hill’s daytime and nighttime noise level standards of 65.0 dBA Leq and 60.0 dBA Leq, respectively. In addition, noise levels to the adjacent cemetery to the east would approach 54.0 dBA Leq, which would be below the exterior noise level standard of 70 dBA L eq for District Four land uses. In addition, on -site HVAC equipment would be shielded by a parapet and roofline that would provide a further noise level reduction. Therefore, long-term stationary noise impacts from the project would be less than significant.

Long-Term Ground-Borne Noise and Vibration from Vehicular Traffic Vibration levels generated from project-related traffic are unusual for on-road vehicles because the rubber tires and suspension systems of on -road vehicles provide vibration isolation. Therefore, project-related vehicular traffic on adjacent roadway s (California Avenue and East Willow Street ) would not result in significant ground-borne noise or vibration impacts.

Land Use Compatibility Analysis
The proposed project would not contain any sensitive outdoor use areas . Therefore, this analysis focuses on the potential interior noise impacts, as described below.

The project proposes a form of air conditioning that would allow windows to remain closed. Exterior noise levels associated with traffic noise along California Avenue at the nearest façade have the potential to approach 71 dBA CNEL, requiring a minimum reduction of 26 dBA to meet 45 dBA CNEL.

The current elevation within the project plans shows that the majority of each façade would be composed of glass. Based on specifications provided, the project would install dual glazed, Solarban 90 glazing. This assembly is made up of two approximately 0.25-inch glass panels separated by a 0.5- inch air space . Typically, this glazing construction would result in a Sound Transmission Class (STC) rating of 35 and Outdoor to Indoor T ransmission Coefficient (OITC) of 28 based on specifications of similar glass panels (Vitro Architectural Glass). A minimum noise reduction of 28 dBA would be expected, resulting in an interior noise level of 43 dBA CNEL , which is below the 45 dBA threshol d.

Therefore, the proposed project would not conflict with any surrounding land uses and no land use impact would occur.

9/29/22 (P:\CLB1904.39 Medical Building CE\CE\2600 California Ave Medical Building Final CE 9_29.docx) 11 Air Quality
The Air Quality and Greenhouse Gas Technical Memorandum for t he Medical Office Building Project at 2600 California Avenue (LSA, August 2022) prepared for the proposed project is provided in Attachment D.

The project site is in the South Coast Air Basin (Basin). Air quality in the Basin is under the jurisdiction of the South Coast Air Quality Management District (SCAQMD). The California Emissions Estimator Model (CalEEMod) was used to calculate emissions from construction and operation of the proposed project.

Construction Emissions
During construction, short-term degradation of air quality may occur due to the release of particulate matter emissions (i.e., fugitive dust) generated by grading, building construction, paving, and other activities. Emissions from construction equipment are also anticipated and would include carbon monoxide (CO), nitrogen oxides (N Ox), volatile organic compounds (VOCs), directly emitted particulate matter less than 2.5 microns in size ( PM

2.5) or particulate matter less than 10 microns in
size (PM10), and toxic air contaminants such as diesel exhaust particulate matter.

Project construction activities would include grading, site preparation, building construction, architectural coating, and paving 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 disturbe d 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. PM
10 emissions would vary from day to day, depending o n the nature and magnitude of construction activity and local weather conditions. PM10 emissions would depend on soil moisture, silt content of soil, wind speed, and amount of operating equipment. Larger dust particles would settle near the source, whereas 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. 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 Rule 403 measures that were incorporated in this analysis include:
• Water active sites at least three times daily (locations where grading is to occur shall be thoroughly watered prior to earthmoving).
• Cover all trucks hauling dirt, sand, soil, or other loose materials, or maintain at least 2 feet (ft) (0.6 meter) of freeboard (vertical space between the top of the load and the top of the trailer) in accordance with the requirements of California Vehicle Code Section 23114. • Reduce traffic speeds on all unpaved roads to 15 miles per hour or less.

9/29/22 (P:\CLB1904.39 Medical Building CE\CE\2600 California Ave Medical Building Final CE 9_29.docx) 12 In addition to dust -related PM10 emissions, heavy trucks and construction equipment powered by gasoline and diesel engines would generate CO, sulfur oxides (SOx), 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 and summarized in Table F.

The results shown in Table F indicate the proposed project would not exceed the significance criteria for daily VOCs, NOx, CO, SOx, PM10, or PM2.5 emissions. Therefore, construction of the proposed project would not result in a cumulatively considerable net increase of any criteria pollutant for which the project region is in nonattainment under an applicable federal or State ambient air quality standards (AAQS).

Operational Air Quality Impacts
Long-term air pollutant emissions associated with operation of the proposed project include emissions from area, energy, and mobile sources. Area- source emissions include architectural coatings, consumer products, and landscaping. Energy -source emissions result from activities in buildings that use electricity and natural gas. Mobile -source emissions are from vehicle trips associated with operation of the project. Area -source emissions consist of direct sources of air emissions at the project si te, including architectural coatings, consumer products, and use of landscape maintenance equipment. PM10 emissions result from running exhaust, tire and brake wear, and t he entrainment of dust into the atmosphere from vehicles traveling on paved roadways .

Entrainment of PM 10 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 diesel-powered vehicles.

9/29/22 (P:\CLB1904.39 Medical Building CE\CE\2600 California Ave Medical Building Final CE 9_29.docx) 13 Energy-source emissions result from activities in buildings that use electricity and natural gas . 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 b uilding or appliance efficiency reduces the amount of energy for a given activity and thus lowe rs 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.

Long-term operational emissions associated with the proposed project were calculated using CalEEMod. Table G provides the proposed project’s estimated operational emissions.

The results shown in Table G indicate the proposed project would not exceed the significance criteria for daily VOC, NO x, CO, SOx, PM10, or PM 2.5 emissions. Therefore, operation of the proposed project would not result in a cumulatively considerable net increase of any criteria pollutant for which the project region is in nonattainment under an applicable federal or State AAQS.

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 vicinity of the proposed project site. Localized air quality impacts would occur when emissions from vehicular traffic increase as a result of the proposed project. The primary mobile-source pollutant of local concern is CO, a direc t function of vehicle idling time and, thus, of traffic flow conditions. CO transport is extremely limited; under normal meteorological conditions, it 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 road ways 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.

9/29/22 (P:\CLB1904.39 Medical Building CE\CE\2600 California Ave Medical Building Final CE 9_29.docx) 14 An assessment of project -related impacts on localized ambient air quality requires that future ambient air quality levels be projected. Existing CO concentrations in the immediate project vicinity are not available. Ambient CO levels monitored at the Los Angeles Monitoring Station located at 7201 W. Westchester Parkway (the closest station to the project site) , showed a highest recorded 1 -hour concentration of 1.8 parts per million ( ppm) (the State standard is 20 ppm) and a highest 8 -hour concentration of 1.3 ppm (the State standard is 9 ppm) from 2019 to 2021. The highest CO concentrations would normally occur during peak traffic hours; hence, CO impacts calculated under peak traffic conditions represent a worst -case analysis. Reduced speeds and vehicular congestion at intersections result in increased CO emissions.

The proposed project is expected to generate 108 average daily trips, with nine trips occurring in the AM peak hour and 12 trips occurring in the PM peak hour. The CO concentrations are not expected to significantly increase as a result of the proposed project. Therefore, given the extremely low level of CO concentrations in the project area and the lack of traffic impacts at any intersections, project - related vehicles are not expected to result in CO concentrations exceeding the State or federal CO standards. No CO hot spot s would occur and the project would not result in any project-related impacts on CO concentrations.

Health Risk on Nearby Sensitive Receptors
Sensitive receptors are defined as people who have an increased sensitivity to air pollution or environmental contaminants. Sensitive receptor locations include schools, parks and playgrounds, daycare centers, nursing homes, hospitals, and residential dwelling units. As discussed above, the closest sensitive air quality receptors include single family residential uses located approximately 400 ft southwest of the project site. The Localized Significance Threshold (LST) analysis was completed to show the construction and operational impacts at 120 meters (400 ft) to the nearest sensitive receptors to the project site in SRA 4, based on a 2-acre project size per the table notes. Tables H and I show the results of the LST analysis during project construction and operation, respectively.

As detailed in Tables H and I, the emission levels indicate that the project would not exceed SCAQMD LSTs during project construction or operation. The project’s peak operational on-site NOx emissions are less than 1.0 lbs/day. Due to the small size of the proposed project in relation to the overall Basin, the level of emissions is not sufficiently high to use a regional modeling program to correlate health effects on a Basin -wide level. On a regional scale, the quantity of emissions from the project is incrementally minor. Because the SCAQMD has not identified any o ther methods to quantify health impacts from small projects and due to the size of the project, it is speculative to assign any specific health effects to small project- related emissions. However, based on this localized analysis, the proposed project woul d not expose sensitive receptors to substantial pollutant concentrations .

Therefore, the project would not expose sensitive receptors to substantial levels of pollutant concentrations.

Odors
Heavy-duty equipment on the project site during construction woul d emit odors, primarily from equipment exhaust. However, the construction activity would cease after individual construction is completed. No other sources of objectionable odors have been identified for the proposed project.

SCAQMD Rule 402 regarding nuis ances states: “A person shall not discharge from any source whatsoever such quantities of air contaminants or other material which cause injury, detriment, nuisance, or annoyance to any considerable number of persons or to the public, or which endanger the comfort, repose, health or safety of any such persons or the public, or which cause, or have a natural tendency to cause, injury or damage to business or property.” The proposed uses are not anticipated to emit any objectionable odors. Therefore, the proposed project would not result in other emissions (such as those leading to odors) adversely affecting a substantial number of people and no impact would occur.

Greenhouse Gas
This section describes the proposed project’s construction - and operation - related greenhouse gas (GHG) emissions and contribution to global climate change. SCAQMD has not addressed emission thresholds for construction in its CEQA Handbook; however, SCAQMD requires quantification and disclosure. Thus, this section discusses construction emissions.

9/29/22 (P:\CLB1904.39 Medical Building CE\CE\2600 California Ave Medical Building Final CE 9_29.docx) 16 Construction Greenhouse Gas Emissions
Construction activities associated with the proposed project would produce combustion emissions from various sources. Construction would emit GHGs through the operation of construction equipment and from worker and builder supply vendor vehicles for the duration of the approximately 6-month construction period. The combustion of fossil -based fuels creates GHGs such as carbon dioxide (CO
2), methane (CH4), and nitrous oxide (N2O). Furthermore, the fueling of heavy equipment emits CH 4. Exhaust emissions from on -site construction activities would vary daily as construction activity levels change. As indicated above, SCAQMD does not have an adopted threshold of significance for construction-related GHG emissions. However, lead agencies are required to quantify and disclose GHG emissions that would occur during construction. The SCAQMD then requires the construction GHG emissions to be amortized over the life of the project, defined as 30 years, added to the operational emissions, and compared to the applicable interim GHG significance threshold tier.

Table J shows carbon dioxide equivalent ( CO2e) emissions calculations for each respective construction phase of the proposed project.

As indicated in Table J, it is estimated that the project would generate 67.3 metric tons (MT) of CO2e during construction of the project. When amortized over the 30 -year life of the project, annual emissions would be 2.2 MT of CO2e.

Operational Greenhouse Gas Emissions
Long-term operation of the proposed project would generate GHG emissions from area, mobile, waste, and water sources as well as indirect emissions from sources associated with energy consumption. Mobile-source GHG emissions would include project-generated vehicle trips associated with trips to the proposed project. Area-source emissions would be associated with activities such as landscaping and maintenance on the p roject site and other sources. Waste source emissions generated by the proposed project include energ y generated by landfilling and other methods of disposal related to transporting and managing project -generated waste. In addition, 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 K shows the estimated operational GHG emissions for the proposed project. Motor vehicle emissions are the largest source of GHG emissions for the project at app roximately 77 percent of the project total. Waste sources are the next largest

As discussed above, a project would have less than significant GHG emissions if it would result in operational-related GHG emissions of less than the scaled SCAQMD threshold of 2,640 MT of CO 2e per year. Based on the analysis results, the proposed project would result in 126.0 CO2e per year , which would be below the numeric threshold of 2,640 MT of CO2e per year. Therefore, operation of the proposed project would not generate significant GHG emissions that would have a significant effect on the environment.

Water Quality
The following analysis relies on the Low Impact Development (LID) Plan 2 and the Hydrology Report3 prepared for the proposed project (Attachments E and F , respectively). Both reports defined the project site as the northern region of the project site which contains an existing passive park 0.26 acre in size and omitted the existing surface parking lot from the analysis, which is located on the southern region because physical development associated with the proposed project would be restricted to the northern area. Therefore, the following analysis is only applicable to the northern area of the project site (0.26 acre).

Construction Water Quality Impacts
Construction activities would involve disturbance, grading, and excavation of soil, which could result in temporary erosion and movement of sediments into the storm drain system, particularly during precipitation events. However, the proposed project would comply with all applicable National Pollutant Discharge Elimination System (NPDES) requirements to reduce impacts to water quality.

Projects that disturb greater than 1 ac re of soil are subject to the requirements of the State Water Resources Control Boar d (SWRCB) Waste Discharge Requirements for Discharges of Storm Water

The proposed project would disturb less than 1 ac re of soil, and therefore, is not required to comply with the requirements of the SWRCB’s Construction General Permit. However, Section 5.106 of the 2019 California Green Building Standards Code (CALGreen Code)4 requires projects that disturb less than 1 acre of soil and that are not part of a larger common plan to prevent pollution of stormwater runoff during construction activities to comply with the local municipal code and/or implement a combination of erosion and sediment control and good housekeeping best management practices (BMPs). The City of Long Beach Municipal Code, Chapter

8.96, Stormwater and Runoff Pollution Control, also requires projects to implement BMPs associated with construction activities to ensure that the potential for soil erosion and sedimentation is minimized and to reduce pollutant discharges. Therefore, impacts to water quality during construction would be less than significant.

According to the Preliminary Geotechnical Investigation 5 prepared for the proposed project, the
depth to groundwater at the project site is anticipated to be greater than 20 ft below ground surface (bgs). At one boring, locating perched groundwater was encountered at a depth of 12 ft. Excavation during construction would be to a maximum depth of 18 to 24 inches bgs. 6 Therefore, due to the depth of groundwater and the proposed depth of excavation, it is not anticipated that groundwater would be encountered during construction; therefore, groundwater dewatering would not be required during construction , and construction-related impacts to groundwater would be less than significant.

Operation Water Quality Impacts
Pollutants of concern during operation of the proposed project include suspended solids/sediments, nutrients, pesticides, heavy metals, oil and grease, toxic organic compounds, and trash and debris.

According to the LID, which only addresses the northern 0.26 -acre portion of the project site being developed, the existing project site is 100 percent pervious. 7 With the development of a medical
building and associated parking lot, t he proposed project would add approximately 2,100 sf of impervious surface area. An increase in impervious surface area would increase the volume of runoff during a storm, which would potentially increase the amount of pollut ants discharged into downstream receiving waters.

The proposed project is subject to the requirements of the Los Angeles Regional Water Quality Control Board’s (RWQCB) Waste Discharge Requirements For Municipal Separate Storm Sewer System (Ms4) Discharges From The City Of Long Beach Order No R4-2014-0024, NPDES No. CAS004003, as Amended By Order No . R4-2014-0024-A01 (Long Beach MS4 Permit). In addition to the Long Beach MS4, the proposed project would be required to comply with Long Beach Municipal Code Section 8.96.130, which requires the development and implementation of structural and nonstructur al BMPs to be implemented on a post -construction basis, a maintenance agreement to assure the proper performance of BMPs, and Long Beach Municipal Code Section 18.74, which requires the preparation

The LID must demonstrate how the project will manage stormwater runoff to prevent stormwater runoff from leaving the site to the maximum extent feasible, for at least the volume of water produced by a storm event that results from:
• The volume of runoff produced from a 0.75-inch storm event; or • The eighty -fifth (85th) percentile twenty -four (24) hour runoff event determined as the maximized capture stormwater volume for the area using a forty -eight (48) to seventy-two (72) hour draw down time, from the formula recommended in Urban Runoff Quality Management, WEF Manual of Practice No. 23/ASCE Manual of Practice No. 87, (1998); or • The volume of annual runoff based on unit basin storage water quality volume, to achieve eighty percent (80%) or more volume treatment by the method r ecommended in the California Stormwater Quality Association, Best Management Practices Handbook – Industrial/Commercial (2003).

According to the LID that was prepared for the proposed project, in the existing condition, stormwater runoff from the northern portion of the project site flows generally to the north and enters the City storm drain system along California Ave nue. In the post project condition, the project site would be divided into three drainage management areas (DMAs) that would each surface drain into a single bioretention basin to treat stormwater runoff. The bioretention basin would include a slotted underdrain which would collect treated stormwater and discharge runoff to the City’s storm drain along California Avenue via a curb drain along the northern edge of the property. Any overflow runoff would be collected by curb drains located on California Ave nue. The City’s municipal storm drain outfalls to the Los Angeles Rive r, which drains to San Pedro Bay which is hydraulically connected to the Pacific Ocean. Implementation of a drainage system and operational BMPs in compliance with the requirements of the Long Beach MS4 Permit and City Municipal Code would ensure project operational impacts to water quality would be less than significant.

Due to the small increase in impervious surface area (2,100 sf), stormwater runoff from the proposed project site would not exceed the capacity of the existing storm drain system.

Project operation would not require groundwater extraction. Water usage for the proposed project would primarily be associated with irrigation for landscaping and fire suppression systems. Because the proposed project would require minimal water use, the proposed project would not generate additional demand for water that would affect groundwater supplies.

In the existing condition, the entire northern portion of the project site is entirely pervious surface area. An increase in impervious surface area decreases infiltration, which can decrease the amount of water that is able to recharge the aquifer/groundwater. However according to the Preliminary Geotechnical Investigation Report
8, the soils underlying the project site do not have a high infiltration rate. Therefore, the small increase in impervious surface area (2,100 sf) would not substantially decrease any infiltration that currently may occur on the project site. Furthermore, the groundwater basin (the West Coast Groundwater Basin of the Los Angeles Coastal P lain in Los Angeles County) underlies 160 square miles and any reduction in on -site infiltration would not be substantial.

9/29/22 (P:\CLB1904.39 Medical Building CE\CE\2600 California Ave Medical Building Final CE 9_29.docx) 20 Therefore, the project would not significantly decrease groundwater supplies or interfere with groundwater recharge.

According to the Federal Emergency Management Agency (FEMA) Flood Insurance Rate Map (FIRM) No. 06037C1966G (April 21, 2021), the project site is not located within a 100- year floodplain.

Specifically, the project site is located within Zone X, an area of minimal flood hazard (outside the 500- year floodplain). According to the Department of Conservation Tsunami Hazard Area Maps, the project site is not located within a Hazard Area.
9 Therefore, there is no risk of tsunami or seiche on
the project site. No project-related impacts associated with flood flows or release of pollutants from inundation would occur.

Overall, the proposed project would not result in impacts associated with hydrology and water quality.

CALIFORNIA ENVIRONMENTAL QUALITY ACT CATEGORICAL EXEMPTIONS —

EXCEPTIONS
State CEQA Guidelines Section 15300.2 provides exceptions that apply to specific types of projects and/or projects where substantial evidence exists that the proposed project involves unusual circumstances. The exceptions to the categorical exemptions pursuant to Section 15300.2 of the State CEQA Guidelines are the following:
(a) Location. Classes 3, 4, 5, 6, and 11 are qualified by consideration of where the project is to be located—a project that is ordinarily insignificant in its impact on the environment may in a particularly sensitive environment be significant. Therefore, these classes are considered to apply all instances, except where the project may impact on an environmental resource of hazardous or critical concern where designated, precisely mapped, and officially ad opted pursuant to law by federal, state, or local agencies.

The proposed project relies on a Class 3 Exemption, but does not qualify as an exception to the exemption under exception A. The project site is located in the City of Long Beach which is an essentially built out urban area. The project site is surrounded on all sides by urban development and is zoned for Institutional Use (I) , which allows medical offices . The project site is not designated by any federal state or local agencies to contain an env ironmental resource. In addition, the proposed project, like all projects, would be subject to the provisions of the MBTA, which prohibits disturbing or destroying active nests, and California Fish and Game Code Section 3503, which protects nests and eggs. Additionally, the proposed project is not located on a site that is included on a list of hazardous- materials sites compiled pursuant to Government Code Section 65962.5. (b) Cumulative Impact. All exemptions for these classes are inapplicable when the cumulative impact of successive projects of the same type in the same place, over time is significant.

The proposed project is a commercial office building in an urbanized area and would be less than 10,000 sf. The proposed project is an in -fill development project in an urban area. According to the Governor’s Office of Planning and Research, the term “infill development” refers to building within unused and underutilized lands within existing development patterns, typically but not exclusively in

9 Department of Conservation. 2021. Los Angeles County Tsunami Hazard Areas.

9/29/22 (P:\CLB1904.39 Medical Building CE\CE\2600 California Ave Medical Building Final CE 9_29.docx) 21 urban areas. Surrounding areas were previously developed with a surface parking lot and small open space area for qualified urban uses as defined by PRC Section 21072. The proposed project would be consistent with existing land use and visual patterns typical of an urban built environment. While a General Plan Amendment would be required to change the PlaceType designation from Open Space to Neo-Industrial (NI), this change would not conflict with surrounding land use patterns or divide an established community. T herefore, the proposed project would not contribute to a significant cumulative land use impact. The proposed project would be visually compatible with surrounding land uses and would not result in or contribute to a significant aesthetic impact.

Neither the project site nor any other project site in the City is currently used for agricultural or farmland production. Neither the project site nor the local area is particularly sensitive in terms of biological resources, and there are no mapped environmentally sensitive habitat areas within or in close proximity to the project site. The proposed project would not result in the loss of known mineral resources or a locally important mineral resource recovery site.

The proposed project would contribute criteria pollutants to the area during project construction. A number of individual projects in the area may be under construction simultaneously with the proposed project. Depending on construction schedules and actual implementation of projects in the area, gene ration of fugitive dust and pollutant emissions during construction could result in substantial short-term increases in air pollutants. However, each project would be required to comply with SCAQMD’s standard construction measures. The proposed project’s short-term construction CO, NO
2, PM10, and PM2.5 emissions would not exceed the LSTs. Therefore, construction of the proposed project would have a less than significant impact with regard to regional and localized emissions, and impacts would not be cumulatively considerable.

As climate change impacts are cumulative in nature, no typical single project can result in emissions of such a magnitude that it, in and by itself, would be significant on a project basis. The proposed project complies with performanc e-based standards included in the California Green Building Standards Code (CALGreen Code) (e.g., the 2022 Building Energy Efficiency Standards ). As GHG emissions would not exceed the SCAQMD Tier 3 numerical screening threshold, the proposed project would result in a less than significant cumulative impact related to GHG emissions. The proposed project was analyzed for consistency with the goals of Assembly Bill (AB) 32, the AB 32 Scoping Plan, Executive Order (EO) B-30-15, SB 32, and AB 197 and SCAG’s 2020– 2045 Regional Transportation Plan/Sustainable Communities Strategy (RTP/SCS). The proposed project’s GHG reduction measures make the proposed project consistent with AB 32, the AB 32 Scoping Plan, EO B-30-15, SB 32, and AB 197 and SCAG’s 2020 –2045 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. Given this consistency, it is concluded that the proposed project’s impacts are not cumulatively considerable.

Energy usage on the project site during construction would be temporary in nature. In addition, energy usage associated with operation of the proposed project would be relatively small in comparison to the State’s available energy sources, and energy impacts would be negligible at the regional level. Because California’s energy conservation planning actions are conducted at a regional level, and because the project’s total impact to regional energy supplies would be minor, the proposed project would not conflict with California’s energy conservation plans as described in the California

9/29/22 (P:\CLB1904.39 Medical Building CE\CE\2600 California Ave Medical Building Final CE 9_29.docx) 22 Energy Commission’s Final 2021 Integrated Energy Policy Report 10. In addition, as indicated above, the proposed project would comply with Title 24 and CALGreen Code standards, consistent with the City’s General Plan. Thus, as shown above, the project would avoid or reduce the inefficient, wasteful, and unnecessary cons umption of energy and not result in any irreversible or irretrievable commitments of energy. Therefore, the proposed project would not result in the wasteful, inefficient, or unnecessary consumption of energy resources during project construction or operat ion. Impacts would not be cumulatively considerable.

There are no buildings on the project site and the site itself is not considered a Historic Landmark .

Additionally, the proposed project would not conflict with any policies set forth by the Historic Preservation element of the General Plan. As there are no existing buildings they do not need to be evaluated as historical resources pursuant to CEQA. As such, project construction and operation would have no impacts to “historical resources” pursuant to State CEQA Guidelines Section 15064.5.

The project site was previously disturbed and developed with a surface parking lot. As such, ground- disturbing ac tivities associated with project construction activities are not likely to directly or indirectly destroy a unique paleontological resource or site or unique geological feature due to the disturbed nature of the project site.

The project site, like all of Southern California, would be subject to seismic ground shaking in the event of an earthquake. The proposed project would be required to comply with the California Building Code in effect at the time of construction and would not exacerbate an existing geologic or seismic hazard.

The proposed project is located in within 2 miles of the Long Beach Airport located at 4100 Donald Douglas Drive in the City of Long Beach. The project site is located outside the boundaries of the Long Beach Airport Planning Bound ary/Airport Influence Area. 11 However, according to the Los Angeles
County Airport Land Use Plan (1991, revised in 2004), the project site is located in the Federal Aviation Administration’s (FAA) Part 77 Notification Area. The purpose of the FAA Part 77 Notification process is to ensure protection of the airspace essential to the safe operation of aircraft at and around airports. Construction of structures within the FAA’s Part 77 Notification Area require that the FAA be notified of construction of any proposed structure(s) which exceed a 50 to 1 imaginary surface slope ratio within 10,000 ft of the nearest runway at a public use airport . The proposed project does not exceed a 50 to 1 imaginary surface slope ratio and therefore does not require Part 77 notification. In addition, due to the nature of this project (i.e., medical office), it would not contribute to the creation of a hazard to the public or the environment involving the transport, use, or disposal of hazardous materials.

As discussed above, wit h compliance with the applicable NPDES permit requirements and implementation of BMPs, project impacts to hydrology and water quality would be less than significant. It is assumed for the purposes of this analysis that the other projects would also comply

The proposed project would not induce substantial population growth or displace housing or substantial numbers of people. The proposed project would not provide new housing opportunities or extend roads or other infrastructure to areas not previously served. The project would include the construction of a 3,000 sf single-story medical office building. The proposed project would represent a negligible increase of jobs. Therefore, no significant impacts to population growth would occur. It is unlikely that the creation of these new jobs would cause any population relocation. Because the proposed project would not increase population in the City, construction and operation of the self - storage facility would not be anticipated to increase the use of existing neighborhood and regional parks or other recreational facilities such that substantial physical deterioration of the facility would occur or be accelerated.

The City is a completely urbanized built out area. The addition of a 3,000 single -story medical office building within a high ly developed region would not alter cumulative regional demand for fire protection services. Nor would the proposed project decrease the officer-to-resident ratio in the City or trigger the need for new or physically altered police facilities. Pursuant to California Education Code Section 17620(a)(1), the governing board of any school district is authorized to levy a fee, charge, dedication, or other requirement against any construction within the boundaries of the district for the purpose of funding the co nstruction or reconstruction of school facilities. Applicant/developers for all projects would be required to pay such fees to reduce any impacts associated with new commercial development on school services.

As stated above, surrounding areas were previously developed for qualified urban uses as defined by PRC Section 21072. As such, the sites are served by all utilities in the existing condition. The LADWP is the water provider for the project site. LADWP maintains and operates the sewer collection system including storm drains, catch basins, and sewer lines. Installation of water and sewer facilities sufficient to serve a proposed project is a standard condition for development projects. The proposed project would also pay any required water and sewer con nection fees. The project site and other regional projects in the City would be provided waste disposal from private contractors and existing landfills. Disposal capacity at these landfills is not constrained at this time, and the proposed project would not be expected to result in or contribute to a significant impact related to waste disposal.

According to the Safety Element of the Public Safety Element of the General Plan (adopted 1975), as a built - out community in an urbanized area, the City of Long Be ach is not subject to substantial wildfire risk.

In summary, the proposed project is a 3,000 sf single -story office building in an urban area. The proposed project would rely on and can be accommodated by the existing road system, public services, and utilities. Impacts of the proposed project would not be cumulatively considerable in connection with the effects of past projects, the effects of other current projects, or the effects of probable future projects.
(c) Significant Effect. A categorical exemptio n shall not be used for an activity where there is a reasonable possibility that the activity will have a significant effect on the environment due to unusual circumstances.

9/29/22 (P:\CLB1904.39 Medical Building CE\CE\2600 California Ave Medical Building Final CE 9_29.docx) 24 The Air Quality and Greenhouse Gas Analysis and the Noise and Vibration Impact Analysis for the proposed project conclude that the proposed project would not result in a significant impact related to these topics. The proposed project would be consistent with the City’s Municipal Code requirements. While the proposed project w ould include a General Plan Amendment to change the project site’s PlaceType designation from Open Space to Neo -industrial (NI), this change would not result in a significant effects on the environment due to unusual circumstances. Given the urban nature of the project site and the compatibility of the proposed project with the character of the surrounding uses, there is no evidence to indicate that the proposed project would have a significant effect on the environment due to unusual circumstances. (d) Scenic Highways. A categorical exemption shall not be used for a project which may result in damage to scenic resources, including but not limited to, trees, historic buildings, rock outcroppings, or similar resources, within a highway officially designated as a state scenic highway. This does not apply to improvements which are required as mitigation by an adopted negative declaration or certified EIR [Environmental Impact Report].

The nearest State-designated scenic highway to the project site is Pacific Coast Highway (SR-1), which is approximately 2.4 miles southeast of the project site (Caltrans 2022)

12. Therefore, the proposed
project does not have the potential to damage resources within a State- designated scenic highway.

No existing scenic rock outcroppings are located within the project limits. The project site is developed with a surface parking lot, which is not eligible for listing as a historic resource. (e) Hazardous Waste Sites. A categorical exemption shall not be used for a project located on a site which is included on any list compiled pursuant to Section 65962.5 of the Government Code.

Pursuant to Government Code Section 65962.5, the Hazardous Waste and Substances Sites List (Cortese List) has been compiled by the California Environmental Protection Agency (CalEPA) Hazardous Materials Data Management Program. The California Department of Toxic Substances Control (DTSC) compiles information from subsets of the following databases to make up the Cortese List:

1. The DTSC list of contaminated or potentially contaminated hazardous waste sites listed in the California Sites database (formerly known as ASPIS)

2. The California SWRCB listing of leaking underground storage tanks

3. The California Integrated Waste Management Board list of sanitary landfills that have evidence of groundwater contamination or known migration of hazardous materials (formerly WB-LF, now Assembly Bill 3750)

9/29/22 (P:\CLB1904.39 Medical Building CE\CE\2600 California Ave Medical Building Final CE 9_29.docx) 25 The proposed project is not located on a site that is included on a list of hazardous-materials sites compiled pursuant to Government Code Section 65962.5. Within one-quarter mile of the project site there are four nonactive Leaking Underground Storage Tanks (LUST) cleanup sites13. (f) Historical Resources. A categorical exemption shall not be used for a project which may cause a substantial adverse change in the significance of a historical resource.

The project site is currently developed with a surface parking lot and an open space area with walking trail. As there are no existing buildings on the project site there are no resources which need to be evaluated as historical resources pursuant to CEQA. As such, project construction and operation would have no impacts to “historical resources” pursuant to State CEQA Guidelines Section 5064.5.

CONCLUSION
In summary, the proposed project would not result in any specific or general exceptions to the use of a Categorical Exemption as detailed under State CEQA Guidelines Section 15332. The proposed project is an office building, in an urbanized area, not exceeding 10,000 sf in floor area on a site zoned for such us e. Additionally, the proposed project would not involve the use of significant amounts of hazardous substances where all necessary public services and facilities are available, and the surrounding area is not an environmentally sensitive area. The proposed project would not cause any impacts to traffic, noise, air quality, or water quality. The project site does not have value as habitat for endangered, rare, or threatened species. The proposed project would not result in damage to a scenic resource within a highway officially designated as a State Scenic Highway. The project site is not on any list compiled pursuant to Section 65962.5 of the Government Code. Furthermore, no unusual circumstances or pot ential cumulative impacts would occur that may reasonably create an environmental impact. Therefore, the proposed project is exempt from the provisions of CEQA as specified by the State CEQA Guidelines identified above.

MEMORANDUM
DATE: August 12, 2022
TO: Alexis Oropeza, Current Planning Officer, City of Long Beach FROM: Arthur Black, Principal Transportation Planner, LSA SUBJECT: Traffic Analysis for Medical Building Project at 2600 California Avenue in Long Beach, California
LSA has prepared this traffic analysis for the proposed construction of an approximately 3,000-square- foot (sf) medical office building (project) at 2600 California Avenue in Long Beach, Californ ia. The proposed project would be constructed on the northern portion of the project site, adjacent to an existing surface parking lot. The existing project site is developed with a surface parking lot, a small portion of open space with a walking path, an d associated landscaping. The project site is generally flat in elevation. Access to the project site would be provided via two driveways on the west side of the project site. The project site would also include an exit-only driveway onto California Avenue, with a right-turn-only restriction. The proposed project would include a passenger drop -off zone directly adjacent to the building entrance.

The proposed project would include 61 parking spaces in total, 49 of which are maintained as off-site parking for the office building located at 999 East Willow Street. The southern portion of the project site includes existing parking, lighting, and landscaping that would continue to provide on-site parking.

The proposed project would include four bicycle parking stalls.

The purpose of this traffic analysis is to identify the potential traffic and circulation effects, as well as the potential California Environmental Quality Act (CEQA) transportation impacts, associated with the proposed project. Thi s traffic analysis identifies the trip generation of the proposed project and determines the vehicle miles traveled (VMT) implications of the proposed project.

Trip Generation
LSA does not believe regional traffic patterns would be altered by the project because existing surface parking spaces are being retained. New traffic generated by the proposed project was calculated using the Institute of Transportation Engineers’ (ITE) Trip Generation Manual, 11 th Edition.1 Table A, below,
presents the trip generation summary for the project. As Table A indicates, the proposed project is anticipated to generate 108 average daily trips (ADT), including 9 trips in the a.m. peak hour and 12 trips in the p.m. peak hour.

Vehicle Miles Traveled Analysis
As a result of Senate Bill (SB) 743, the California Office of Administrative Law cleared the revised State CEQA Guidelines for use on December 28, 2018. Concurrent with the revised State CEQA Guidelines, the Governor’s Office of Planning and Research released the Technical Advisory on Evaluating Transportation Impacts in CEQA (December 2018). As currently adopted, the CEQA guidelines indicate that VMT generated by a land use project is generally the most appropriate measure of transportation impacts. The City of Long Beach Traffic Impact Analysis Guidelines (June 2020) establish screening thresholds, analysis methodology, and significance thresholds for VMT analyses in Long Beach.

Both the City guid elines and the State’s Technical Advisory provide screening thresholds for small projects. The City guidelines screen out projects generating fewer than 500 daily trips as the greenhouse gas emissions resulting from this level of vehicle traffic would be less than comparable to greenhouse gas emissions thresholds. The State’s Technical Advisory recommends that development with fewer than 110 daily trips be presumed to have a less than significant impact because projects with this level of traffic are likely to fit the criteria established for a categorical exemption for CEQA analysis.

Based on the trip generation shown in Table A, the project would generate 108 daily trips, which is below the screening thresholds described above. Therefore, the project is pr esumed to have a less than significant impact on VMT.

Conclusion
Based on the results of this traffic analysis, the project would have a less than significant impact on vehicle level of service and VMT.

TO: Alexis Oropeza, Current Planning Officer, City of Long Beach FROM: J.T. Stephens, Principal
Moe Abushanab, Noise Engineer
SUBJECT: Noise and Vibration Impact Analysis Memorandum for the Medical Office Building Project at 2600 California Avenue in the City of Long Beach, California

INTRODUCTION
This noise and vibration impact analysis has been prepared to evaluate the potential impacts associated with the proposed Medical Office Building (project) located at 2600 California Avenue in the City of Long Beach (City), California, in support of a Categorical Exemption (CE) . This report is intended to satisfy the City’s requirement for a project-specific noise and vibration impact analysis by examining the short-term and long-term noise and vibration impacts on sensitive uses adjacent to the project site. This report also evaluates noise impacts to the proposed sensitive uses that would be developed as part of the project and identifies the necessary project design features and standard project conditions.

PROJECT LOCATION
The 0. 72-acre project site is a long , thin, rectangular parcel located on the northeast corner of California Avenue and East Willow Street on Assessor’s Parcel Number (APN) 7212-009-017 in Long Beach, California. The existing project site is developed with a surface parking lot, a small portion of open space with a walking path, and associated landscaping. The project site is generally flat in elevation. In the project site’s existing condition, vehicular access is provided via two one -way driveways on California Avenue.

The project site is surrounded by a mixture of open space, office, and retail uses. The project site is bounded to the east by a cemetery, to the north by an urban farm, to the west by California Avenue and office uses, and to the south by East Willow Street and retail uses. Regional access to the project site is provided by Interstates 405 (I -405) and 710 (I-710), which are located approximately 0.6 mile north and 1.5 miles west of the project site, respectively. Local access to the project site is provided by California Avenue and East Willow Street . The project location and conceptual site plan are presented on Figures 1 and 2 , respectively . All figures are pr ovided in Attachment B of this memorandum.

PROJECT DESCRIPTION
The proposed project would construct an approximately 3,000 -square-foot (sf) single-story medical office building located towards the northern end of the proj ect site. Figure 2, Conceptual Site Plan,

9/12/22 «P:\CLB1904.39 Medical Building CE\Technical Studies\Noise\Noise and Vibration Memo 9-12-22.docx» 2 provides an overview of the proposed site plan, including the location of the proposed building, parking areas, trash enclosure, transformer, and associated landscaping.

A trash enclosure, 8 feet (ft) in height, would be included on the northeastern corner of the project site. The trash enclosure would include a concrete tilt-up roof along with swinging gates and a roof. A proposed transformer would be located immediately south of the building’s exterior southeast corner. The proposed project would include 61 parking spaces in total, 49 of which are maintained as off-site parking for the office building located at 999 East Willow Street.

The proposed building would have a building footprint of 9.64 percent of the total project site (31,275 sf). The overall height of the medical office building is proposed to be a maximum of 24 ft, 8 inches.

The building entrance would be provided at the northwest corner and would be Americans with Disabilities Act ( ADA) accessible. The proposed building windows would be a dual -pane storefront system, with 65 percent visible light transmittance.

Construction would include vegetation removal, excavation, grading, building construction, and the installation of landscaping and irrigation, lighting, storm drain facilities, and underground utilities.

Construction of the proposed project is anticipated to commence in 2023 and would take approximately 6 months.

Based on the preliminary grading plans, approximately 350 cubic yards wou ld be exported from the project site. Demolition, grading, and building activities would involve the use of standard earthmoving equipment such as large excavators, cranes, and other related equipment.

METHODOLOGY
Evaluation of noise and vibration impacts associated with the proposed project will include the following:
• Determine the short-term construction noise levels at off-site sensitive uses and compare those levels to the City’s Municipal Code Ordinance requirements; • Determine the long -term noise levels at off -site sensitive uses and compare th ose levels to the City's pertinent noise standards;
• Determine the short-term construction-related vibration levels at off- site sensitive uses and compare those levels to the Federal Transit Administration’s (FTA) vibration thresholds1; and • Determine the required project design features, such as mechanical ventilation or building façade enhancements, to reduce long-term, on-site noise impacts from all sources.

1 The City’s General Plan Noise Element does not include standard criteria for assessing vibration impacts but suggests, for the purpose of determining the significance of vibration impacts experienced at s ensitive uses surrounding the project, the use of the guidelines within the FTA’s Transit Noise and Vibration Impact Assessment Manual (FTA 2018).

9/12/22 «P:\CLB1904.39 Medical Building CE\Technical Studies\Noise\Noise and Vibration Memo 9-12-22.docx» 3 CHARACTERISTICS OF SOUND
Noise is usually defined as unwanted sound. Noise consists of any sound that may produce physiological or psychological damage and/or interfere with communication, work, rest, recreation, and sleep.

To the human ear, sound has two significant characteristics: pitch and loudness. Pitch is generally an annoyance, while loudness can affect the ability to hear. Pitch is the number of complete vibrations, or cycles per second, of a wave resulting in the tone’s range from high to low. Loudness is the strength of a sound that describes a noisy or quiet environment and is measured by the amplitude of the sound wave. Loudness is determined by the intensity of the sound waves combined with the reception characteristics of the human ear. Sound intensity is the av erage rate of sound energy transmitted through a unit area perpendicular to the direction in which the sound waves are traveling. This characteristic of sound can be precisely measured with instruments. The analysis of a project defines the noise environment of the project area in terms of sound intensity and its effect on adjacent sensitive land uses.

Measurement of Sound
Sound intensity is measured through the A -weighted scale to correct for the relative frequency response of the human ear. That is, an A -weighted noise level de -emphasizes low and very high frequencies of sound similar to the human ear’s de-emphasis of these frequencies. Unlike linear units (e.g., inches or pounds), decibels are measured on a logarithmic scale , which is a scale based on multiples of 10.

For example, 10 decibels (dB) is 10 times more intense than 0 dB, 20 dB is 100 times more intense than 0 dB, and 30 dB is 1,000 times more intense than 0 dB. Thirty decibels (30 dB) represents 1,000 times as much acoustic energy as 0 dB. The decibel scale increases as the square of the change, representing the sound pressure energy. A sound as soft as human breathing is about 10 times greater than 0 dB. The decibel system of measuring sound gives a rough connection between the physical intensity of sound and its perceived loudness to the human ear. A 10 dB increase in sound level is perceived by the human ear as only a doubling of the sound’s loudness. Ambient sounds generally range from 30 dB (very quiet) to 100 dB (very loud).

Sound levels are generated from a source, and their decibel level decreases as the distance from that source increases. Sound dissipates exponentially with distance from the noise source. For a single - point source, sound levels decrease approximately 6 dB for each doubling of distance from the source.

This drop-off rate is appropriate for noise generated by stationary equipment. If noise is produced by a line source (e.g., highway traffic or railroad operations) the sound decreases 3 dB for each doubling of distance in a hard site environment. Similarly, line sources with intervening absorptive vegetation or line sources which are located at a great distance to the receptor would decrease 4.5 dB for each doubling of distance.

There are many ways to rate noise for various t ime periods, but an appropriate rating of ambient noise affecting humans also accounts for the annoying effects of sound. The equivalent continuous sound level (L
eq) is the total sound energy of time- varying noise over a sample period. However, the predominant rating scales for human communities in the State of California are the L eq and Community Noise Equivalent Level (CNEL) or the day -night average noise level (L dn) based on

9/12/22 «P:\CLB1904.39 Medical Building CE\Technical Studies\Noise\Noise and Vibration Memo 9-12-22.docx» 4 A-weighted decibels (dBA). CNEL is the time -weighted average noise over a 24 -hour period, with a 5 dBA weighting factor applied to the hourly L eq for noises occurring from 7:00 p.m. to 10:00 p.m. (defined as relaxation hours), and a 10 dBA weighting factor applied to noises occurring from 10:00 p.m. to 7:00 a.m. (defined as sleeping h ours). Ldn is similar to the CNEL scale but without the adjustment for events occurring during the relaxation hours. CNEL and L dn are within 1 dBA of each other and are normally interchangeable. The City of Long Beach uses the CNEL noise scale for long - term noise impact assessment.

Other noise rating scales of importance when assessing the annoyance factor include the maximum instantaneous noise level (L max), which is the highest sound level that occurs during a stated time period. The noise environments discussed in this analysis for short -term noise impacts are specified in terms of maximum levels denoted by Lmax, which reflects peak operating conditions and addresses the annoying aspects of intermittent noise. It is often used together with another noise scale or noise standards in terms of percentile noise levels in noise ordinances for enforcement purposes. For example, the L
10 noise level represents the noise level exceeded 10 percent of the time during a stated period. The L50 noise level represents the median noise level (i.e., half the time the noise level exceeds this level, and half the time it is less than this level). The L 90 noise level represents the noise level exceeded 90 percent of the time and is considered the background noise level during a monitoring period. For a relatively constant noise source, the Leq and L50 are approximately the same.

Noise impacts can be described in three categories. The first is audible impacts that refer to increases in noise levels noticeable to humans. Audible increases in noise levels generally refer to a change of

3.0 dB or greater because this level has been found to be barely perceptible in exterior environments.

The second category, potentially audible, refers to a change in the noise level between 1.0 and 3.0 dB. This range of noise levels has been found to be noticeable only in laboratory environments. The last category is changes in noise levels of less than 1.0 dB, which are inaudible to the human ear. Only audible changes in existing ambient or background noise levels (3.0 dB or greater) are considered potentially significant.

Physiological Effects of Noise
Physical damage to human hearing begins at prolonged exposure to noise levels higher than 85 dBA.

Exposure to high noise levels affects the entire system, with prolonged noise exposure in excess of 75 dBA increasing body tensions, thereby affecting blood pressure and functions of the heart and the nervous system. In comparison, extended periods of noise exposure above 90 dBA would result in permanent cell damage. When the noise level reaches 120 dBA, a tickling sensation occurs in the human ear even with short-term exposure. This level of noise is called the threshold of feeling. As the sound reaches 140 dBA, the tickling sensation is replaced by the feeling of pain in the ear. This is called the threshold of pain. A sound level of 160–165 dBA will result in dizziness or loss of equilibrium. The ambient or background noise problem is widespread and generally more concentrated in urban areas than in outlying less developed areas. Table A lists definitions of acoustical terms, and Table B shows common sound levels and their sources.

Term Definitions
Decibel, dB A unit of level that denotes the ratio between two quantities proportional to power, the number of decibels is 10 times the logarithm (to the base 10) of this ratio.

Frequency, Hz Of a function periodic in time, the number of times that the quantity repeats itself in one second (i.e., number of cycles per second).

A-Weighted Sound Level, dBA The sound level obtained by use of A-weighting. The A-weighting filter deemphasizes the very low and very high frequency components of the sound in a manner similar to the frequency components of the sound in a manner similar to the frequency response of the human ear and correlates well with subjective reactions to noise. All sound levels in this assessment are A-weighted, unless reported otherwise.

L01, L10, L50, L90 The fast A-weighted noise levels equaled or exceeded by a fluctuating sound level for 1 percent, 10 percent, 50 percent, and 90 percent of a stated time period.

Equivalent Continuous Noise Level, Leq The level of a steady sound that, in a stated time period and at a stated location, has the same A-weighted sound energy as the time varying sound.

Community Noise Equivalent Level, CNEL The 24-hour A-weighted average sound level from midnight to midnight, obtained after the addition of 5 dB to sound levels occurring in the evening from 7:00 p.m. to 10:00 p.m. and after the addition of 10 dB to sound levels occurring in the night between 10:00 p.m. and 7:00 a.m.

Day/Night Noise Level, Ldn The 24-hour A-weighted average sound level from midnight to midnight, obtained after the addition of 10 dB to sound levels occurring in the night between 10:00 p.m. and 7:00 a.m.

Lmax, Lmin The maximum and minimum A-weighted sound levels measured on a sound level meter, during a designated time interval, using fast time averaging.

Ambient Noise Level The all-encompassing noise associated with a given environment at a specified time, usually a composite of sound from many sources at many directions, near and far; no particular sound is dominant.

Intrusive The noise that intrudes over and above the existing ambient noise at a given location. The relative intrusiveness of a sound depends upon its amplitude, duration, frequency, and time of occurrence and tonal or informational content, as well as the prevailing ambient noise level.

CHARACTERISTICS OF VIBRATION
Vibration refers to ground -borne noise and perceptible motion. Ground -borne vibration is almost exclusively a concern inside buildings and is rarely perceived as a problem outdoors, where the motion may be discernible. Typically, there is more adverse reaction to effects associated with the shaking of a building. Vibration energy propagates from a source through intervening soil and rock layers to the foundations of nearby buildings. The vibration then propagates from the foundation throughout the remainder of the structure. Building vibration may be perceived by occupants as the motion of building surfaces, the rattling of items on shelves or hanging on walls, or a low -frequency rumbling noise. The rumbling noise is caused by the vibration of walls, floors, and ceilings that radiate sound waves. Annoyance from vibration often occurs when the vibration exceeds the threshold of perception by 10 dB or less. This is an order of magnitude below the damage threshold for normal buildings.

Typical sources of ground -borne vibration are construction activities (e.g., blasting, pile driving, and operating heavy-duty earthmoving equipment), steel-wheeled trains, and occasional traffic on rough roads. Problems with both ground-borne vibration and noise from these sources are usually localized

9/12/22 «P:\CLB1904.39 Medical Building CE\Technical Studies\Noise\Noise and Vibration Memo 9-12-22.docx» 7 to areas within approximately 100 ft from the vibration source, although there are examples of ground-borne vibration causing interference out to di stances greater than 200 ft (Caltrans 2013 ).

When roadways are smooth, vibration from traffic, even heavy trucks, is rarely perceptible. It is assumed for most projects that the roadway surface will be smooth enough that ground -borne vibration from street traffic will not exceed the impact criteria; however, the construction of the project could result in ground-borne vibration that may be damaging.

Ground-borne vibration has the potential to damage buildings. Although it is very rare for typical construction activities to cause even cosmetic building damage, it is not uncommon for construction processes such as blasting and pile driving to cause vibration of sufficient amplitudes to damage nearby buildings ( Caltrans 2013). Ground-borne vibration is usually measured in terms of vibration velocity, either the root-mean-square (RMS) velocity or peak particle velocity (PPV). The PPV is used to characterize potential for structure damage.

THRESHOLDS OF SIGNIFICANCE
Based on the Guidelines for the Implementation of the California Environmental Quality Act (CEQA), Appendix G, Public Resources Code, Sections 15000–15387, a project will normally have a significant effect on the environment related to noise if it will substantially increase the ambient noise levels for adjoining areas or conflict with adopted environmental plans and the goals of the community in which it is located. The following are the thresholds for potential noise impacts.

REGULATORY SETTING
The following section summarizes the regulatory framework related to noise, including federal, State, and City of Long Beach plans, policies, and standards.

Federal Regulations
In 1972, Congress enacted the United States Noise Control Act. This act authorized the United States Environmental Protection Agency (USEPA) to publish descriptive data on the effects of noise and establish levels of sound “requisite to protect the public welfare with an adequate margin of safety.” These levels are separated into health (hearing loss levels) and welfare (annoyance levels). For protection against hearing loss, 96 pe rcent of the population would be protected if sound levels are less than or equal to 70 dBA during a 24-hour period of time. At 55 dBA L dn, 95 percent sentence clarity
(intelligibility) may be expected at 11 ft, with no community reaction. However, 1 perce nt of the population may complain about noise at this level and 17 percent may indicate annoyance. The USEPA cautions that these identified levels are guidelines, not standards.

State Regulations
The State of California has established regulations that help prevent adverse impacts to occupants of buildings located near noise sources. Referred to as the State Noise Insulation Standard, it requires buildings to meet performance standards through design and/or building materials that would offset any noise source in the vicinity of the receptor. State regulations include require ments for the construction of new hotels, motels, apartment houses, and dwellings other than detached single- family dwellings that are intended to limit the extent of noise transmitted into habitable spaces. These requirements are found in the California Code of Regu lations, Title 24 (known as the Building Standards Administrative Code), Part 2 (known as the California Building Code), Appendix Chapters

9/12/22 «P:\CLB1904.39 Medical Building CE\Technical Studies\Noise\Noise and Vibration Memo 9-12-22.docx» 8 12 and 12A. For limiting noise transmitted between adjacent dwelling units, the noise insulation standards specify the extent to which walls, doors, and floor-ceiling assemblies must block or absorb sound. For limiting noise from exterior noise sources, the noise insulation stan dards set an interior standard of 45 dBA CNEL in any habitable room with all doors and windows closed.

Local and Regional Policies and Regulations
City of Long Beach Noise Element
The City of Long Beach General Plan addresses noise in its Noise Element. The proposed Draft Noise Element, released in May 2019, has not yet been adopted . The Noise Element contains goals and policies for noise control and abatement in the City. The goals and policies contained in the Noise Element address noise in relation to land use planning, the noise environment, transportation noise, construction and industrial noise, population and housing noise, and public health and safety. General noise goals for Long Beach aim to attain a healthier and quieter environment for all citiz ens while maintaining a reasonable level of economic progress and development.

The City, consistent with the California Office of Planning and Research, has established land use compatibility guidelines for determining acceptable noise lev els for specified land uses as shown in Table C. The se land use compatibility guidelines are intended to be an advisory resource when considering changes in land use and policies, such as zoning modifications.

City of Long Beach Municipal Code
The City of Long Beach addresses noise impacts in Title 8: Health and Safety, Chapter 8.80, Noise , of its Municipal Code. Chapter 8.80, Noise, establishes exterior noise limits for the generation of sound within the City. The maximum noise levels vary based on the receiving land use type and the cumulative duration of noise. Table D summarize those noise limits.

In addition, Section 8.80.150(C) states the following:
“If the measured ambient level exceeds that permissible within any of the first four (4) noise limit categories in Subsection B of this Section, the allowable noise exposure standard shall be increased in five (5) decibels increments in each category as appropriate to encompass or reflect the ambient noise level. In the event the ambient noise level exceeds the fifth noise limit category in Subsection B of this Section, the maximum allowable noise level under said category shall be increased to reflect the maximum ambient noise level.”

City of Signal Hill Municipal Code
The nearest sensitive receptor, the Long Beach Islamic Center, is located within the City of Signal Hill.

The City of Signal Hill addresses noise impacts in its Municipal Code, Chapter 9.16, Noise. Section

9.16.020 establishes ambient base noise levels at receiving land uses, as presented in Table E, below.

The ambient noise level is defined as “the level obtained when the noise level is averaged over a period of fifteen minutes without inclusion of noise from isolated identifiable sources, at the location and time of day near that at which a comparison is to be made.”

In addition, Section 9.16.060 states the following:
“It is unlawful for any person to operate any machinery, equipment, compressor, pump, generator, fan, air conditioning apparatus, or similar mechanical device, or provide boarding or daycare to animals in an enclosed building (kennel) in any manner so as to create any noise which would cause the noise level at the property line of any property to exceed the ambient noise level by more than five decibels.” Noise regulations established by the City of Long Beach also affect noise levels in Signal Hill. As discussed in the previous section, the City of Long Beach has implemented an Airport Noise Compatibility Ordinance which effectively limits noise for neighborhoods in both Long Beach and Signal Hill.

9/12/22 «P:\CLB1904.39 Medical Building CE\Technical Studies\Noise\Noise and Vibration Memo 9-12-22.docx» 11 Applicable Vibration Standards
The City’s Noise Element does not include specific criteria for assessing vibration impacts; it suggests that for the purpose of determining the significance of vibration impacts experienced at sensitive uses surrounding the project, the guidelines within the FTA ’s 2018 Transit Noise and Vibration Impact Assessment Manual (FTA Manual) should be used to determine vibration impacts.

The criteria for environmental impact s from ground -borne vibration and noise are based on the maximum levels for a single event. Table F lists the potential vibration building damage criteria associated with construction activities , as suggested in the FTA Manual. FTA guidelines show that a vibration level of up to 0.5 inches per second (in/sec) in PPV is considered safe for buildings consisting of reinforced concrete, steel, or timber (no plaster), and would not result in any construction vibration damage. For a nonengineered timber and masonry building, the construction building vibration damage criterion is 0.2 in/sec in PPV.

Table F: Construction Vibration Damage Criteria
Building Category PPV (in/sec)
Reinforced concrete, steel, or timber (no plaster) 0.50 Engineered concrete and masonry (no plaster) 0.30
Non-engineered timber and masonry buildings 0.20

EXISTING SETTING
Sensitive Receptors and Land Uses in the Project Vicinity Certain land uses are considered more sensitive to noise and vibration than others. Examples of these include residential areas, educational facilities, hospitals, childcare facilities, places of worship, and senior housing. The project site is surrounded primarily by open space, office, and commercial uses.

The closest sensitive receptors include the following:
• Northwest: Long Beach Islamic Center across East 27th Street • East: Sunnyside Cemetery (Per the City’s Municipal Code, this land use falls under District Four.) The project site has a c urrent General Plan PlaceType designation of Open Space. The proposed project would require a General Plan Amendment to change the PlaceType designation to Neo Industrial (NI). The NI PlaceType designation permits land uses associated with offices . According to the City’s 2017 Land Use Zoning Map, the project site is currently zoned for Institutional Use (I). The proposed project would be consistent with the project site’s current zoning designation as permitted uses in the Institutional Zoning District include medical offices and complexes.

Overview of the Existing Noise Environment
The primary existing noise sources in the project area are traffic noise on California Avenue and East Willow Street, parking lot activities, and commercial activities. Also, aircraft takeoffs associated with the Long Beach Airport contribute to the existing noise environment in the project vicinity.

9/12/22 «P:\CLB1904.39 Medical Building CE\Technical Studies\Noise\Noise and Vibration Memo 9-12-22.docx» 12 Long-Term Noise Measurements
Long-term (24-hour) noise level measurements were conducted on May 5 and May 6, 2022, using two (2) Larson Davis Spark 706RC Dosimeters. Table G provides a summary of the measured hourly noise levels and calculated CNEL levels from the long-term noise level measurements. As shown in Table G, the calculated CNEL levels range from 65.1 dBA CNEL to 68.2 dBA CNEL. Hourly noise levels at surrounding sensitive uses are as low as 54.0 dBA Leq during nighttime hours and 60.1 dBA Leq during daytime hours. Long-term noise monitoring data results are provided in Attachment C. Figure 3 shows the long-term monitoring locations. Because the measured noise levels are below the ambient noise levels established by the City of Signal Hill Municipal Code, the noise levels from Signal Hill’s Municipal Code presented in Table E will be utilized as the noise limits in the assessment of noise impacts to the Long Beach Islamic Center as it is located within the City of Signal Hill boundary, while the noise limits presented in Table D for the City of Long Beach will be utilized for the assessment of noise impacts to Sunnyside Cemetery.

Aircraft Noise
Long Beach Airport is located approximately 1.25 miles northeast of the project site. The Los Angeles County Airport Land Use Plan (ALUC 2004) shows that the project site is well outside the 65 dBA CNEL noise contour for the airports. While aircraft operations may contribute to the noise in the project area from th is airport, the project site is not expected to experience airport- related noise levels in excess of the City of Long Beach exterior standards.

PROJECT IMPACT ANALYSIS
The project would result in short-term construction noise and vibration impacts and long-term mobile and stationary source noise and vibration impacts as described below.

9/12/22 «P:\CLB1904.39 Medical Building CE\Technical Studies\Noise\Noise and Vibration Memo 9-12-22.docx» 13 Short-Term Construction-Related Impacts
Project construction would result in short -term noise and vibration impacts on adjacent land use s.

Maximum construction impacts would be short -term, generally intermittent depending on the construction phase, and variable depending on rece ptor distance from the active construction area.

The duration of impacts generally would be from one day to several days depending on the phase of construction. The level s and types of impacts that would occur during construction are described below.

The first type of short-term construction noise would result from transport of construction equipment and materials to the project site and construction work er commutes. These transportation activities would incrementally raise noise levels on access roads leading to the site. It is expected that larger trucks used in equipment delivery would generate higher noise impacts than trucks associated with worker commutes. The single-event noise from equipment trucks passing at a distance of 50 ft from a sensitive noise receptor would reach a maximum level of 84 dBA Lmax. However, the pieces of heavy equipment for grading and construction activities would be moved on site only one time and would remain on site for the duration of each construction phase. This one -time trip, when heavy construction equipment is moved on and off site, would not significantly add to the traffic noise experienced over a 24-hour period in the project vicinity. The total number of daily vehicle trips would be minimal when compared to existing traffic volumes on the affected streets, and the long -term noise level change associated with these trips would not be perceptible. Therefore, equipment transport noise and construction -related worker commute impacts would be short- term and would not result in a significant off-site noise impact.

The second type of short- term noise impact is related to noise generated during site preparation, grading, building construction, architectural coating, and paving on the project site. Construction is undertaken in discrete steps, each of which has its own mix of equipment, and consequently its own noise characteristics. These various sequential phases would chan ge the character of the noise generated on the project site. Therefore, the noise levels vary as construction progresses. Despite the variety in the type and size of construction equipment, similarities in the dominant noise sources and patterns of operati on allow construction -related noise ranges to be categorized by work phase.

Table H lists the maximum noise levels recommended for noise impact assessments for typical construction equipment based on a distance of 50 ft between the equipment and a noise receptor.

Typical operating cycles for these types of construction equipment may involve 1 to 2 minutes of full power operation followed by 3 to 4 minutes at lower power settings.

Utilizing the equations from the methodology above and the reference informati on in Table E, the composite noise level of each construction phase was calculated. The project construction composite noise levels at a distance of 50 ft would range from 74 dBA Leq to 85 dBA Leq based on a 40 percent usage factor, with the highest noise levels occurring during the grading phase.

Construction noise levels will fluctuate throughout the construction period as equipment moves between the various areas on the project site. In order to assess the specific noise levels at the surrounding receptors, the average noise level experienced during construction was assessed based on the average distance of activities to the surrounding receptors that would be approximately 185 ft from the property line of the existing Long Beach Islamic Center to the northwest and approximately 30 ft from the property line of the existing sensitive Sunnyside Cemetery to the east. At the estimated distances, construction noise levels experienced would be 73.0 dBA and 78.0 dBA for the Islamic center and the cemetery, respectively.

Although the project construction noise would be higher than the ambient noise in the project vicinity, it would cease to occur once the project construction is completed . The p roposed project would comply with the requirements of the City of Long Beach Noise Ordinance, which states that construction activities shall only occur between the hours of 7:00 a.m. to 7:00 p.m., Monday through Friday and federal holidays; or between 9:0 0 a.m. to 6:00 p.m. on Saturdays. Construction shall not occur on Sundays. Additionally, construction noise levels on average are expected to be below the FTA’s recommended 90 dBA L
eq standard. Compliance with the Noise Ordinance would ensure that construction noise does not disturb surrounding receptors during hours when ambient noise levels are likely to be lower (i.e., at night). In addition, the proposed project would implement several best practices for reducing construction noise, including, but not l imited to, maximizing the distance between noise sources and sensitive receptors during construction activities, and equipping construction equipment with properly operating and maintained noise mufflers . In conclusion, construction noise would be reduced to a less than significant level with compliance with the City’s Municipal Code allowable construction hours, and incorporation of the recommended best business practices. No mitigation is required.

Construction Vibration Impacts
Ground-borne noise and vibration from construction activity would be mostly low to moderate. While there is currently limited information regarding vibration source levels, to provide a comparison of vibration levels expected for a project of this size, a small bulldozer and loaded truck , as shown in Table I, would generate approximately 0 .003 in/sec in PPV and 0.076 in/sec in PPV , respectively, of ground-borne vibration when measured at 25 ft. Table F further shows the PPV values from other construction vibration sources at 25 ft from construction vibration sources for comparison purposes.

As shown in Table F , vibration levels exceeding 0.5 in/sec in PPV would result in building damage to structures constructed of non-engineered timber and masonry buildings. The closest receptor to the proposed construction activities is the existing Long Beach Islamic Center at 995 East 27th Street, Signal Hill, which is located 160 ft northwest of the boundary of the proposed project.

Based on the traffic analysis results, it was determined that a net additional 108 average daily trips (ADT) would be generated by the proposed project. The Existing traffic volume on the adjacent segment of East Willow Street from Atlantic Avenue to Cherry Avenue is 29,350 (Southern California Association of Governments [ SCAG] 2017). Using the equation below, with an increase of 108 ADT, the noise level increase would be less than 0.1 dBA CNEL.

Change in CNEL = 10 log10 [Ve+p/Vexisting]
Where: Vexisting = the existing daily volume
Ve+p = existing daily volumes plus project
Change in CNEL = the increase in noise level due to the project A noise level increase of less than 1 dBA would not be perceptible to the human ear ; therefore, the traffic noise increase along East Willow Street resulting from the project would be less than significant.

9/12/22 «P:\CLB1904.39 Medical Building CE\Technical Studies\Noise\Noise and Vibration Memo 9-12-22.docx» 17 Long-Term Stationary Noise Impacts
The proposed project would include mechanical equipment related to heating, ventilation, and air conditioning (HVAC) equipment which could operate 24 hours per day. Rooftop HVAC would generate noise levels of 66.6 dBA Leq at 5 ft per HVAC unit based on previous measurements conducted by LSA.

Based on the site plan, two HVAC units will be installed and would generate noise levels of 69.6 dBA Leq at 5 ft. Table J presents the noise levels from HVAC equipment at the nearest noise -sensitive location.

In addition, noise levels to the adjacent cemetery to the east would approach 54.0 dBA Leq, which would be below the exterior noise level standard of 70 dBA Leq for District Four land uses , as identified in Table D previously. In addition, on-site HVAC equipment would be shielded by a parapet and roofline that would provide a further noise level reduction.

Long-Term Ground-Borne Noise and Vibration from Vehicular Traffic Vibration levels generated from project -related traffic are unusual for on-road vehicles because the rubber tires and suspension systems of on -road vehicles provide vibration isolation. Therefore, project-related vehicular traffic on adjacent roadway s (California Avenue and East Willow Street ) would not result in significant ground-borne noise or vibration impacts.

Land Use Compatibility Analysis
The proposed project would not contain any sensitive outdoor use areas. Therefore, this analysis focuses on the potential interior noise impacts, as described below.

Interior Noise Analysis
The project proposes a form of air conditioning that would allow windows to remain closed. Exterior noise levels associated with traffic noise along California Avenue at the nearest façade h ave the potential to approach 71 dBA CNEL, requiring a minimum reduction of 26 dBA to meet 45 dBA CNEL.

The current elevation withi n the project plans shows that the majority of each façade would be

9/12/22 «P:\CLB1904.39 Medical Building CE\Technical Studies\Noise\Noise and Vibration Memo 9-12-22.docx» 18 composed of glass. Based on specifications provided, the project would install dual glazed, Solarban 90 glazing. This assembly is made up of two approximately 0.25-inch glass panels separated by a 0.5- inch air space . Typically, this glazing construction would result in a Sound Transmission Class (STC) rating of 35 and Outdoor to Indoor Transmission Coefficient (OITC) of 28 based on specifications of similar glass panels (Vitro Architectural Glass). A minimum noise reduction of 28 dBA would be expected, resulting in an interior noise level of 43 dBA CNEL, which is below the 45 dBA threshold.

SUMMARY
Based on the analysis above, the proposed project would be in compliance with the City of Long Beach and the City of Signal Hill noise standards with the implementation of the following project design features and regulatory compliance measures . The Project Applicant should verify that final design plans reflect the following design features:
• The proposed project includes installation of central air conditioning which allows windows to remain closed.
• Windows and glass doors with rating of STC 35 or higher for the exterior façades.

In addition, during project construction, the following best business practices would reduce potential noise increases to the extent feasible:
• The project shall comply with the City’s permitted hours of construction , which is 7:00 a.m. to 7:00 p.m., Monday through Friday and on federal holidays; and 9 :00 a.m. to 6 :00 p.m. on Saturdays. Construction shall not occur on Sundays.
• The project construction contractor shall ensure that the greatest distance between noise sources and sensitive receptors during construction activities is achieved. • The project construction contractor shall equip c onstruction equipment, fixed or mobile, with properly operating and maintained noise mufflers consistent with manufacturers’ standards. • The project contractor shall place all stationary construction equipment so that emitted noise is directed away from sensitive receptors nearest the project site whenever feasible. • The project construction contractor shall use on-site electrical sources to power equipment rather than diesel generators whenever feasible.
• The project construction contractor shall reduce non -essential idling of construction equipment to no more than five minutes per hour.

FROM: Amy Fischer, Principal
Cara Carlucci, Senior Planner
SUBJECT: Air Quality and Greenhouse Gas Technical Memorandum for the Medical Office Building Project at 2600 California Avenue in the City of Long Beach, California

INTRODUCTION
LSA has prepared this Air Quality and Greenhouse Gas Technical Memorandum to evaluate the impacts associated with construction and operation of the proposed Medical Building Project (project) located at 2600 California Avenue in the City of Long Beach (City), Los Angeles County, California. This analysis was prepared using methods and assumptions recommended in the air quality impact assessment guidelines of the South Coast Air Quality Management District (SCAQMD) in its CEQA Air Quality Handbook (1993) and associated updates. This analysis includes an assessment of criteria pollutant emissions, an assessment of carbon monoxide (CO) hot-spot impacts, and an assessment of the project’s greenhouse gas (GHG) emissions.

PROJECT LOCATION
The 0.72-acre project site is located on the northeast corner of California Avenue and East Willow Street (Assessor’s Parcel Number [APN] 7212-009-017) in the City of Long Beach, Los Angeles County, California. The existing project site is developed with a surface parking lot, a small open space area with a walking path, and associated landscaping. The project site is generally flat in elevation.

The project site is surrounded by a mixture of open space, office, and retail uses. The project site is bounded to the east by a cemetery, to the north by an urban farm, to the west by California Avenue and office uses, and to the south by East Willow Street and retail uses. Regional access to the project site is provided by Interstates 405 (I -405) and 710 (I-710), which are located approximately 0.6 mile north and 1.5 miles west of the project site, respectively. Local access to the project site is provide d by California Avenue and East Willow Street . The project location is shown in Figure 1 (provided in Attachment A).

PROJECT DESCRIPTION
The proposed project would include the construction of a 3,000 -square-foot medical office and associated improvements located towards the northern end of the project site. The southern portion of the project site includes existing parking and associated landscaping , which would not include physical development besides the inclusion of the proposed transformer. The proposed transformer

9/12/22 (P:\CLB1904.39 Medical Building CE\Technical Studies\AQ GHG\Medical Building CE AQ GHG Memo 9-12-22.docx) 2 would be located immediately south of the building’s exterior on the southeast corner. The proposed project would include 61 parking spaces in total, 49 of which are maintained as off-site parking for the office building located at 999 East Willow Street.

Typical operational characteristics include employees and patients traveling to and from the site. The project is assumed to operate 24 hours per day, 7 days per week; however, this may shift depending on the tenant, as the hours of operation are unknown. The proposed project is expected to generate approximately 108 average daily trips.

Construction of the proposed project is anticipated to commence in 2023 and would take approximately 6 months. Based on the preliminary grading plans, approximately 350 cubic yards would be exported fr om the project site. Demolition, grading, and building activities would involve the use of standard earthmoving equipment such as large excavators, cranes, and other related equipment.

EXISTING LAND USES IN THE PROJECT AREA
For the purposes of this analys is, sensitive receptors are areas of the population that have an increased sensitivity to air pollution or environmental contaminants. Sensitive receptor locations include residences, schools, daycare centers, hospitals, parks, and similar uses that are sensitive to air quality. Impacts on sensitive receptors are of particular concern because th ose receptors are the population most vulnerable to the effects of air pollution. The project site is surrounded primarily by open space, office, and retail uses . The areas adjacent to the project site include the following uses:

Sunnyside Cemetery to the east, an urban farm to the north opposite E 27th Street, California Avenue and office uses to the west, and retail uses to the south by E ast Willow Street. The closest sensitive receptors to the project site include single family residential uses located approximately 400 feet southwest of the project site.

ENVIRONMENTAL SETTING
Air Quality Background
Air quality is primarily a function of local climate, local sources of air pollution, and regional pollution transport. The amount of a given pollutant in the atmosphere is determined by the amount of the pollutant released and the atmosphere’s ability to transport and dilute the pollutant. The major determinants of transport and dilution are wind, atmospheric stability, terrain and, for photochemical pollutants, sunshine.

A region’s topographic features have a direct correlation with air pollution flow and therefore are used to determine the boundary of air bas ins. The proposed project is in Long Beach , Los Angeles County, and is within the jurisdiction of SCAQMD, which regulates air quality in the South Coast Air Basin (Basin).

The Basin comprises approximately 10,000 square miles and covers all of Orange Count y and the urban parts of Los Angeles, Riverside, and San Bernardino C ounties. The Basin is on a coastal plain

9/12/22 (P:\CLB1904.39 Medical Building CE\Technical Studies\AQ GHG\Medical Building CE AQ GHG Memo 9-12-22.docx) 3 with connecting broad valleys and low hills to the east. Regionally, the Basin is bounded by the Pacific Ocean to the southwest and high mountains to the east, forming the inland perimeter.

Both State and federal governments have established health-based Ambient Air Quality Standards for six criteria air pollutants: CO, ozone (O 3), nitrogen dioxide (NO 2), sulfur dioxide (SO 2), lead (Pb), and suspended particulate matter. 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. Two criteria pollutants, O 3 and NO2, are considered regional pollutants because they (or their precursors) affect air quality on a regional scale.

Pollutants such as CO, SO
2, and Pb are considered local pollutants that tend to accumulate in the air locally.

Air quality monitoring stations are located throughout the nation and are maintained by the local air districts and State air quality regulating agencies. Data collected at permanent monitoring stations are used by the United State Environmental Pr otection Agency ( EPA) to identify regions as “attainment” or “nonattainment” depending on whether the regions meet the requirements stated in the applicable National Ambient Air Quality Standards (NAAQS). Nonattainment areas are imposed with additional restrictions as required by the EPA. In addition, different classifications of attainment (e.g., marginal, moderate, serious, severe, and extreme) are used to classify each air basin in the State on a pollutant -by-pollutant basis. The classifications are used as a foundation to create air quality management strategies to improve air quality and to comply with the NAAQS. As shown in Table A, the Basin is designated as nonattainment by federal standards for O 3 and particulate matter less than

2.5 microns in diameter (PM2.5) and nonattainment by State standards for O3, particulate matter less than 10 microns in diameter (PM10), and PM2.5.

9/12/22 (P:\CLB1904.39 Medical Building CE\Technical Studies\AQ GHG\Medical Building CE AQ GHG Memo 9-12-22.docx) 4 O3 levels, as measured by peak concentrations and the number of days over the State 1-hour standard, have declined substantially as a result of aggressive programs by SCAQMD and other regional, State, and federal agencies. The reduction of peak concentration s represents progress in improving public health; however, the Basin still exceeds the State standard for 1 -hour and 8-hour O3 levels. The EPA lowered the 1997 0.80 parts per million (ppm) national 8 -hour ozone standard to 0.75 ppm in 2008 and then to 0.70 ppm on October 1, 2015. The Basin is classified nonattainment for the 1-hour and 8- hour ozone standards at the State and federal level. 2019 data were not available; therefore, in 2020 and 2021, the Signal Hill Air Monitoring Station located at 1710 E 20th Street (the closest monitoring station to the project site) recorded the following exceedances of the State and federal 1-hour and 8- hour O3 standards.1
• The federal 8-hour ozone standard had 4 exceedances in 2020 and no exceedances in 2021. • The State 8-hour ozone standard had 4 exceedances in 2020 and no exceedances in 2021. • The State 1 -hour ozone standard had 4 exceedances in 2020 and an unknown number of exceedances in 2021.

National and State standards have also been established for PM 2.5 over 24-hour and yearly averaging periods. PM2.5, because of the small size of individual particles, can be especially harmful to human health. PM2.5 is emitted by common combustion sources such as cars, trucks, buses, and power plants, in addition to ground-disturbing activities. On December 17, 2006, the EPA strengthened the 24 -hour PM2.5 NAAQS from 65 micrograms per cubic meter (µg/m3) to 35 µg/m3, and the Basin was subsequently designated “moderate” nonattainment for 2006 24 -hour PM 2.5 NAAQS on December 14, 2 009. The Basin is also considered a nonattainment area for the PM2.5 standard at the State level. No exceedances of the federal 24 -hour PM2.5 were recorded at the Long Beach Monitoring Station located at 1305 E.

Pacific Coast Highway (the closest station to the project site monitoring PM2.5) during the 2019 to 2021 time period.

The Basin is classified as a PM 10 nonattainment area at the State level and was redesignated from serious nonattainment to attainment of the federal PM10 standard on July 26, 2013. Because the Basin was redesignated from nonattainment to attainment, a PM10 maintenance plan was adopted in 2013 and is required to be updated every 10 years. From 2019 to 2021, the Long Beach Air Monitoring Station located at 1305 E. Pacific Coast Highway (the closest monitoring station to the project site ) recorded no exceedances of the federal 24-hour PM10 standard were measured at the Long Beach Air Monitoring Station during the 2019–2021 time period.

All areas of the Basin have continued to remain below the federal CO standards (35 ppm 1 -hour and 9 ppm 8-hour standards) since 2003. The EPA redesignated the Basin to attainment of the federal CO standards, effective June 11, 2017. The Basin is also well below the State CO standards (20 ppm 1-hour CO and 9 ppm 8-hour CO).

9/12/22 (P:\CLB1904.39 Medical Building CE\Technical Studies\AQ GHG\Medical Building CE AQ GHG Memo 9-12-22.docx) 5 Greenhouse Gas and Global Climate Change Background
GHGs are present in the atmosphere naturally, are released by natural sources, or form from secondary reactions taking place in the atmosphere. 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. Although manmade GHGs include naturally occurring GHGs such as carbon d ioxide (CO
2), methane (CH 4), and nitrous oxide (N 2O), some gases like hydrofluorocarbons (HFCs), perfluorocarbons ( PFCs), nitrogen trifluoride ( NF3), and sulfur hexafluoride (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.

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 GWP is based on several factors, including the relative effectiveness of a gas to absorb infrared radiation and length of time that the gas remains in the atmosphere (“atmospheric lifetime”). The GWP of each gas is measured relative to CO
2, 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).

REGULATORY SETTING
This section provides regulatory background information for air quality, GHGs, and energy.

Air Quality
Applicable federal, State, regional, and local air quality regulations are discussed below.

Federal Regulations
The 1970 Federal Clean Air Act (CAA) authorized the establishment of national health-based air quality standards and set deadlines for their attainment. The CAA Amendments of 1990 changed deadlines for attaining national standards as well as the remedial actions required for areas of the nation that exceed the standards. Un der the CAA, 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.

State Regulations
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 CO, O 3, SO2, and NO2 by
the earliest practical date. The CCAA provides districts with the authority to regulate indirect sources and mandates that air quality districts focus particular attention on reducing emissions from

9/12/22 (P:\CLB1904.39 Medical Building CE\Technical Studies\AQ GHG\Medical Building CE AQ GHG Memo 9-12-22.docx) 6 transportation and area- wide emission sources. Each nonattainment district is required to adopt a plan to achieve a 5 percent annual redu ction, 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 California Air Resources Board (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 co ntaminants, and oversee compliance with air pollution rules and regulations.

Regional Regulations
The proposed project would be required to comply with regional rules that assist in reducing short - term air pollutant emissions. SCAQMD Rule 403 requires that fugitive dust be controlled with best available control measures so the presence of such dust does not remain visible in the atmosphere beyond the property line of the emission s source. In addition, SCAQMD Rule 403 requires implementation of dust suppression techniques to prevent fugitive dust from creating a nuisance off site. SCAQMD Rule 1113 limits the volatile organic compound (VOC) content of architectural coatings.

Applicable dust suppression techniques from SCAQMD Rule 403 and low VOC content in paints under SCAQMD Rule 1113 are summarized below. Implementation of these dust suppression techniques can reduce the fugitive dust generation (and thus the PM 10 component). Compliance with these rules
would reduce impacts on nearby sensitive receptors.

South Coast Air Quality Management District Rule 403 Measures. • Water active sites at least twice daily (locations where grading is to occur will be thoroughly watered prior to earthmoving).
• All trucks hauling dirt, sand, soil, or other loose materials are to be covered or should maintain at least 2 feet (ft) of freeboard in accordance with the requirements of California Vehicle Code Section 23114 (freeboard means vertical space between the top of the load and top of the trailer). • Traffic speeds on all unpaved roads shall be reduced to 15 miles per hour or less.

South Coast Air Quality Management District Rule 1113 Measures. SCAQMD Rule 1113 governs the sale, use, and manufactu re of architectural coating and limits the VOC content in paints and pain t solvents. This rule regulates the VOC content of paints available during construction and operation of the proposed project. Therefore, all paints and solvents used during construction and operation of the proposed project must comply with SCAQMD Rule 1113.

Local Regulations
City of Long Beach General Plan Air Quality Element (1996).The adopted City of Long Beach General Plan addresses air quality in its Air Quality Element and contains goals and policies and actions in relation to government organization roles and responsibilities, ground transportation, air transportation, land use, particulate emissions, energy conservation, and education. The following

9/12/22 (P:\CLB1904.39 Medical Building CE\Technical Studies\AQ GHG\Medical Building CE AQ GHG Memo 9-12-22.docx) 7 policies related to air quality are presented in the Air Quality Element 2 and are applicable to the proposed project:
• Policy 2.1.1: Reduce Vehicle Trips. Use incentives, regulations, and transportation demand management techniques, in cooperation with other jurisdictions in the South Coast Air Basin to eliminate vehicle trips that would otherwise occur.
• Policy 2.1.2: Reduce Vehicle Mi les Traveled. Use incentives, regulations, and transportation demand management in cooperation with other jurisdictions in the South Coast Air Basin, to reduce vehicle miles traveled.
• Policy 7.1: Energy Conservation. Reduce energy consumption through conse rvation improvements and requirements.
• Policy 7.2: Recycle Wastes. Promote local recycling of wastes and the use of recycled materials.

Greenhouse Gas Emissions
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 EPA has the authority to regulate CO 2 emissions under the CAA.

Although there currently are no adopted federal regulations for the control or reduction of GHG emissions, the EPA commenced several actions in 2009 to implement a regulatory approach to global climate change, including the 2009 EPA final rule for mand atory reporting of GHGs from large GHG emission sources in the United States. Additionally, the EPA Administrator signed an endangerment finding action in 2009 under the CAA , finding that seven GHGs (CO2, CH4, N2O, HFCs, NF3, PFCs, and SF6) constitute a th reat 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.

State Regulations
CARB is the lead agency for implementing climate change regulations in the State. Since its formation, 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 32 (2006), Californ ia Global Warming Solutions Act. California’s major initiative for reducing GHG emissions is Assembly Bill (AB) 32, passed by the State legislature on August 31, 2006.

This effort set a GHG emission reduction target to reduce 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 CO 2e.

The emissions target of 427 MMT requires the reduction of 169 MMT from the State’s projected

2 City of Long Beach. 1996. Long Beach General Plan. December. Website: https://www.longbeach.gov/lbds /planning/advance/general-plan/ (accessed May 2022).

9/12/22 (P:\CLB1904.39 Medical Building CE\Technical Studies\AQ GHG\Medical Building CE AQ GHG Memo 9-12-22.docx) 8 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 CARB approved the Scoping Plan on Decembe r 11, 2008. It 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 emissio ns level of 596 MMT of CO2e under a business-as-usual scenario (this is a reduction of 42 MMT of 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 reduction of 31.7 MMT of CO2e); • The Low-Carbon Fuel Standard (15.0 MMT of CO2e);
• Energy efficiency measures in buildings and appliances and the widespread development of combined heat and power systems (26.3 MMT of CO2e); and • A renewable portfolio standard for electricity production (21.3 MMT of CO2e).

The Scoping Plan identifies 18 emission redu ction 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 of CO 2e 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 California Enviro nmental Quality Act ( 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.

The CARB approved the First Update to the Climate Change Scoping Plan on May 22, 2014 . The First Update identifies opportunities to leverage existing and new funds to further drive GHG emissions reductions through strategic planning and targeted low carbon investments. The First Update defines CARB climate change priorities until 2020 and sets the groundwork to reach long-term goals set forth in Executive Orders (EOs) 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 ,3 to reflect the 2030 target set by EO B-30-15 and codified by Senate Bill (SB) 32.

Senate Bill 375 (2008). Signed into law on October 1, 2008, SB 375 supplements GHG reductions from new vehicle technology and fuel standards with reductions from more efficient land use patterns and

9/12/22 (P:\CLB1904.39 Medical Building CE\Technical Studies\AQ GHG\Medical Building CE AQ GHG Memo 9-12-22.docx) 9 improved transportation. Under the law, the CARB approved GHG reduction targets in February 2011 for California’s 18 federally designated regional planning bodies, known as Metropolitan Planning Organizations (MPOs). The CARB may update the targets every 4 years and must update them every 8 years. MPOs, in turn, must demonstrate how their plans, policies , and transportation investments meet the targets set by the CARB through Sustainable Community Strategies (SCS). The SCS s are included with the Regional Transportation Plan, a report required by State law. Howeve r, if an MPO finds that its SCS will not meet the GHG reduction target, it may prepare an Alternative Planning Strategy. The Alternative Planning Strategy identifies the impediments to achieving the targets.

Executive Order B-30-15 (2015). Governor Jerry Brown signed EO 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 Reductio n Act. SB 350, signed by Governor Je rry 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 • Increase 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 (CPUC) for the private utilities and by the CEC for municipal utilities. Each utility m ust submit a procurement plan showing it will purchase clean energy to displace other nonrenewable resources. The 50 percent increase in energy efficiency in buildings must be achieved through the use of existing energy efficiency retrofit funding and regu latory tools already available to S tate energy agencies under existing law. The addition made by this legislation requires S tate energy agencies to plan for and implement those programs in a manner that achieves the energy efficiency target.

9/12/22 (P:\CLB1904.39 Medical Building CE\Technical Studies\AQ GHG\Medical Building CE AQ GHG Memo 9-12-22.docx) 10 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 A B 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 Brown’s April 2015 EO B-30-15. SB 32 builds on AB 32 and keeps us on the path toward achieving the State’s 2050 objective of reducing emissions to 80 percent below 1990 levels, consistent with an Intergovernmental Panel on Climate Change analysis of the emission trajectory that would stabilize atmospheric GHG concentrations at 450 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 Brown signed SB 100, which raises California’s renewable 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 zero-carbon 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 W estern grid or allow resource shuffling to achieve the 100 percent carbon-free electricity target.

Executive Order B -55-18. EO 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.” EO B-55-18 directs CARB to work with relevant State agencies to ensure future Scoping Plans identify and r ecommend 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 CO 2e from the atmosphere, including through sequestration in forests, soils, and other natural landscapes.

Title 24, Building Efficiencies Standards, and the California Green Building Standards Code. In November 2008, the California Building Standards Commission established the California Green Building Standards Code (CALGreen Code) (California Code of Regulations , Title 24, Part 11), which sets performance standards for residential and nonresidential development to reduce environmental impacts and to encourage sustainable construction practices. The CALGreen Code addresses energy efficiency, water conservation, material conservation, planning and design, and overall environmental quality. The CALGreen Code was most recently updated in 2019 to include new mandatory measures for residential and nonresidential uses. The new measures took effect January 1, 2020.

Regional Regulations
Southern California Association of Governments . SCAG is a regional council consisting of the following six counties: Imperial, Los Angeles, Orange, Riverside, San Bernardino, and Ventura. In total, the SCAG region encompasses 191 cities and over 38,000 square miles within Southern California.

SCAG is the MPO serving the region under federal law and serves as the Joint Powers Authority, the Regional Transportation Planning Agency, and the Council of Governments under State law. As the

9/12/22 (P:\CLB1904.39 Medical Building CE\Technical Studies\AQ GHG\Medical Building CE AQ GHG Memo 9-12-22.docx) 11 Regional Transportation Planning Agency, SCAG prepares long -range transportation plans for the Southern California region, including the RTP/SCS and the 2008 Regional Comprehensive Plan (RCP).

On September 3, 2020 , SCAG adopted Connect SoCal –The 2020 –2045 Regional Transportation Plan/Sustainable Communities Strategy (2020 –2045 RTP/SCS).4 In general, the SCS 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 (VMT) 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. The RTP/SCS lays ou t a strategy for the region to meet these targets. Overall, the SCS 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 plan for more active lifestyles.
5 However, the SCS does not require that local General Plans, Specific Plans, or zoning be consistent with the SCS; instead, it provides incentives to governments and developers for consistency.

South Coast Air Quality Management District. In 2008, 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 Plans (2008) that could be applied by lead agencies. On September 28, 2010, SCAQMD Working Group Meeting #15 provided further guidance, including a tiered approach for evaluating GHG emissions for development projects where SCAQMD is not the lead agency. SCAQMD has not presented a finalized version of these thresholds to the governing board.

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, SCAQMD identifies a GHG efficiency level that, when applied Statewide or to a d efined geographic area, would meet the 2020 and post -2020 emission 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 would be able to accommodate expected population gr owth and achieve economic development objectives while also abiding by AB 32’s emissions target and future post - 2020 targets. The SCAQMD has established a flow chart for evaluating GHG significance and indicates that when a project is exempt from CEQA, no further analysis is required.

City of Long Beach Sustainable City Action Plan. The City of Long Beach’s Sustainable City Action Plan (SCAP) was adopted in February 2010. The SCAP is intended to guide operational, policy, and financial decisions to create a more sustainable Long Beach. The SCAP includes initiatives, goals, and actions that will move Long Beach toward becoming a sustainable city. These goals and actions included in the SCAP relate to the following:
• Buildings & Neighborhoods • Urban Nature
• Energy • Waste Reduction
• Green Economy & Lifestyle • Water
• Transportation
City of Long Beach Draft Climate Action and Adaptation Plan (CAAP). The City of Long has recently adopted the Climate Action and Adaptation Plan (CAAP). 6 The CAAP 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, incent ives, 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 (CAAP Checklist) which w ould be used for future projects to determine their consistency with the CAAP.

METHODOLOGY
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 so il disturbance, fuel combustion from mobile heavy -duty, diesel- and gasoline -powered equipment, portable auxiliary equipment, and worker commute trips.

The California Emissions 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. This analysis assumes that construction would begin in 2023 and would last approximately 6 months. This analysis also assumes the use of Tier 2 construction equipment and that the proposed project would comply with SCAQMD Rule 403 measures . Based on the preliminary

9/12/22 (P:\CLB1904.39 Medical Building CE\Technical Studies\AQ GHG\Medical Building CE AQ GHG Memo 9-12-22.docx) 13 grading plans, approximately 350 cubic yards would be exported from the project site, which was included in CalEEMod. Demolition, grading, and building activities would involve the use of standard earthmoving equipment such as large excavators, cranes, and other related equipment. All o ther 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
This air quality analysis includes estimating emissions associated with long -term operation of the project. Indirect emissions of criteria pollutants with regional impacts would be emitted by project - generated vehicle trips. In addition, localized air quality impacts (i.e., higher carbon monoxide concentrations or “hot-spots”) near intersections or roadway segments in the project vicinity would also potentially occur due to project-generated vehicle trips.

Consistent with 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 Location and Description section, the proposed project would develop a 3,000-square-foot medical office building and associated improvements. The analysis was conducted using land use codes Medical Office Building, City Park, and Parking Lot. Trip generation rates used in CalEEMod for the project were based on the project’s estimated trip generation of 108 average daily trips.

Greenhouse Gas Emissions
GHG emissions associated with the p roject 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 p roject-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 do any of the following:
• 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 • Result in other emissions (such as those leading to odors) affecting a substantial number of people

9/12/22 (P:\CLB1904.39 Medical Building CE\Technical Studies\AQ GHG\Medical Building CE AQ GHG Memo 9-12-22.docx) 14 Certain air districts (e.g., SCAQMD) have created guidelines and requirements to conduct air quality analysis. The SCAQMD’s current guidelines, the CEQA Air Quality Handbook7 with associated updates, were followed in this assessment of air quality impacts for the proposed project.

Regional Emissions Thresholds
SCAQMD has established daily emission thresholds for construction and operation of a proposed project in the Basin. The emission thresholds were established based on the attainment status of the Basin with regard to air quality standards for specific crite ria pollutants. Because the concentration standards were set at a level that protects public health wit h an adequate margin of safety , these emission thresholds are regarded as conservative and would overstate an individual project’s contribution to health risks. Table B lists t he CEQA significance thresholds for construction and operational emissions established for the Basin.

CO = carbon monoxide
lbs/day = pounds per day
NOX = nitrogen oxides
PM2.5 = particulate matter less than 2.5 microns in size PM10 = particulate matter less than 10 microns in size
SCAQMD = South Coast Air Quality Management District
SOX = sulfur oxides
VOC = volatile organic compound

Projects in the Basin with construction - or operation -related emissions that exceed an y of their respective emission thresholds would be considered significant under SCAQMD guidelines. These thresholds, which the 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.

Local Microscale Concentration Standards
The significance of localized project impacts under CEQA depends on whether ambient CO leve ls 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 exc eedance of one or more of the 1-hour or 8-hour standards. The following are applicable local emission concentration standards for CO:

• California State 8-hour CO standard of 9 ppm
Localized Impacts Analysis
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. 8 This guidance was used to analyze potent ial localized air quality impacts associated with construction of the proposed project. Localized significance thresholds (LSTs) 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 South Coastal Los Angeles County area (SRA 4). SCAQMD provides LST screening tables for 25, 50, 100, 200, and 500-meter (m) source-receptor distances. As identified above, the closest sensitive receptors to the project site include single family residential uses located approximately 400 feet southwest of the project site. An LST analysis was completed to show the construction and operation al impacts at a distance of 120 meters (400 ft) to the nearest sensitive receptors. Based on the anticipated construction equipment, the maximum daily disturbed acreage for the proposed project was modeled for 2 acres

• Conflict with an applicable plan, policy or regulation adopted for the purpose of reduction the emissions of greenhouse gases.

To provide guidance to local lead agencies on determining significance for GHG emissions in their CEQA documents, SCAQMD has convened a GHG CEQA Signif icance Threshold Working Group (Working Group). Based on the last Working Group meeting held in September 2010 (Meeting No. 15), SCAQMD proposed to adopt a tiered approach for evaluating GHG emissions for development projects where SCAQMD is not the lead agency:
• Tier 1. Exemptions: If a project is exempt from CEQA, project-level and cumulative GHG emissions are less than significant.
• Tier 2. Consistency with a Locally Adopted GHG Reduction Plan: If the project complies with a GHG emissions reduction plan or mitigation program that avoids or substantially reduces GHG emissions in the project’s geographic area (i.e., city or county), project-level and cumulative GHG emissions are less than significant.
• Tier 3. Numerical Screening Threshold: If GHG emissions are less than the numerical screening - level threshold, project-level and cumulative GHG emissions are less than significant. • Tier 4. Performance Standards: If emissions exceed the numerical scree ning threshold, a more detailed review of the project’s GHG emissions is warranted. The SCAQMD has proposed an efficiency target for projects that exceed the bright- line threshold. The current recommended approach is per-capita efficiency targets. The SCAQMD is not recommending use of a percentage emissions reduction target. Instead, the SCAQMD proposes proposed a 2020 efficiency target of

4.8 MT of CO
2e per year per service population for project-level analyses and 6.6 MT of CO2e per year per service popul ation for plan-level projects (e.g., program -level projects such as General Plans).

Because the project would begin operations in the post -2020 timeframe, the 2020 numerical screening threshold of 3,000 MT of CO2e and the efficiency target of 4. 8 MT of CO2e per year per service population would need to be adjusted to reflect the State’s post-2020 GHG reduction goals.

CARB has completed a Scoping Plan, which will be utilized by the SCAQMD to establish the 2030 GHG efficiency threshold. SCAQMD has yet to publish a quantified GHG efficiency threshold for the 2030 target. A scaled threshold consistent with State goals detailed in SB 32, EO B-30-15, and EO S-3-05 to reduce GHG emissions by 40 percent below 1990 levels by 2030 and 80 percent below 1990 levels by 2050, respectively, was developed for 2023 , when construction of the proposed project would be completed. Though th e SCAQMD has not published a quantified threshold beyond 2020, this assessment uses a threshold of 2, 640 MT of CO
2e per year or 4.2 MT of CO2e per year per service
population, which was calculated for the project operational year of 2023 based on the GHG reduction goals of SB 32 and EO B-30-15.

9/12/22 (P:\CLB1904.39 Medical Building CE\Technical Studies\AQ GHG\Medical Building CE AQ GHG Memo 9-12-22.docx) 17 For the purpose of this analysis, the proposed project will be compared to the adjusted screening- level Tier 3 Numerical Screening Threshold of 2,640 MT of CO2e per year.

IMPACT ANALYSIS
This section identifies pote ntial air quality and GHG impacts associated with implementation of the proposed project.

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 project-related vehicular trips and due to energy consumption (e.g., electricity and natural gas usage) by 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.

The proposed project would include a 3,000-square-foot medical office building. The proposed project is not considered a project of Statewide, regional, or area-wide significance (e.g., large-scale projects such as airports, electrical generating facilities, petroleum and gas refineries, residential development of more than 500 dwelling units, shopping center or business establishment employing more than 1,000 persons or encompassing more than 500,000 square feet of floor space) as defined in the California Code of Regulations (Title 14, Division 6, Chapter 3, Article 13, §15206(b)). Because the proposed project would not be defined as a regionally significant project under CEQA, it does not meet the Southern California Association of Governments’ (SCAG) Intergovernmental Review criteria.

The City’s General Plan is consistent with the SCAG Regional Comprehensive Plan Guidelines and the SCAQMD Air Quality Management Plan (AQMP). Pursuant to the methodology provided in the SCAQMD’s CEQA Air Quality Handbook , consistency with the Basin 201 6 AQMP is affirmed when a project (1) would not increase the frequency or severity of an air quality standards violation or cause a new violation, and (2) is consistent with the growth assumptions in the AQMP. Consistency review is presented as follows:

1. The project would result in short -term construction and long-term operational pollutant emissions that are all less than the CEQA significance emissions thresholds established by SCAQMD, as demonstrated below; therefore, the project in would not result in an increase in the frequency or severity of an air quality standards violation or cause a new air quality standard violation.

2. The CEQA Air Quality Handbook indicates that consistency with AQMP growth assumptions must be analyzed for new or amended General Plan elements, Specific Plans, and significant projects.

9/12/22 (P:\CLB1904.39 Medical Building CE\Technical Studies\AQ GHG\Medical Building CE AQ GHG Memo 9-12-22.docx) 18 Significant projects include airports, electrical generating facilities, petroleum and gas refineries, designation of oil drilling districts, water ports, solid waste disposal sites, and offshore drilling facilities; therefore, the proposed project is not defined as significant.

Based on the consistency analysis presented above, the proposed project would be consistent with the regional AQMP.

Criteria Pollutant Analysis
The Basin is currently designated nonattainment for the federal and State standards for O 3 and PM2.5.

In addition, the Basin is in nonattainment for the PM10 standard. The Basin’s nonattainment status is attributed to the region’s development history. Past, present, and future development projects contribute to the region’s adverse air quality impacts on a cumulative basis. By its very nature, air pollution is largely a cumulative impact. No single project is sufficient in size to, by itself, result in nonattainment of an ambient air quality standard. Instead, a project’s individual emissions contribute to existing cumulatively significant adverse air quality i mpacts. If a project’s contribution to the cumulative impact is considerable, then the project’s impact on air quality would be considered significant.

In developing thresholds of significance for air pollutants, SCAQMD considered the emission levels for which a project’s individual emissions would be cumulatively considerable. If a project exceeds the identified significance thresholds, its emissions would be cumulatively considerable, resulting in significant adverse air quality impacts to the region’s ex isting air quality conditions. Therefore, additional analysis to assess cumulative impacts is not necessary. The following analysis assesses the potential project-level air quality impacts associated with construction and operation of the proposed project.

Construction Emissions. During construction, short-term degradation of air quality may occur due to the release of particulate matter emissions (i.e., fugitive dust) generated by grading, building construction, paving, and other activities. Emissions from construction equipment are also anticipated and would include CO, nitrogen oxides ( NO
x), VOC, directly emitted PM 2.5 or PM 10, and toxic air contaminants such as diesel exhaust particulate matter.

Project construction activities would include grading, site preparation, building c onstruction, architectural coating, and paving 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 addit ional source of airborne dust after it dries. PM 10 emissions would vary from day to day, depending on the nature and magnitude of construction activity and local weather conditions. PM 10 emissions would depend on soil moisture, silt content of soil, wind speed, and amount of operating equipment. Larger dust particles would settle near the source, wh ereas 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. SCAQMD has established Rule 403: Fugitive Dust, which would require the

9/12/22 (P:\CLB1904.39 Medical Building CE\Technical Studies\AQ GHG\Medical Building CE AQ GHG Memo 9-12-22.docx) 19 applicant to implement measures that would reduce the amount of particulate matter generated during the construction period. The Rule 403 measures that were incorporated in this analysis include:
• Water active sites at least three times daily (locations where grading is to occur shall be thoroughly watered prior to earthmoving).
• Cover all trucks hauling dirt, sand, soil, or other loose mate rials, or maintain at least 2 feet (0.6 meter) of freeboard (vertical space between the top of the load and the top of the trailer) in accordance with the requirements of California Vehicle Code Section 23114. • Reduce traffic speeds on all unpaved roads to 15 miles per hour or less.

In addition to dust -related PM
10 emissions, heavy trucks and construction equipment powered by gasoline and diesel engines would generate CO, sulfur oxides (SO x), NO x, VOCs and some soot particulate (PM2.5 and PM10) in exhaust em issions. 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 and summarized in Table D.

Attachment B provides CalEEMod output sheets.

Maximum Daily Regional Pollutant Emissions (lbs/day)

Note = Values may not appear to add up correctly due to rounding.

The results shown in Table D indicate the proposed project would not exceed the significance criteria for daily VOC, NOx, CO, SOx, PM10, or PM2.5 emissions. Therefore, construction of the proposed project would not result in a cumulatively considerable net increase of any criteria pollutant for which the project region is in nonattainment under an applicable federal or State AAQS.

Operational Air Quality Impacts. Long-term air pollutant emissions associated with operation of the proposed project include em issions from area, energy, and mobile sources. Area-source emissions

9/12/22 (P:\CLB1904.39 Medical Building CE\Technical Studies\AQ GHG\Medical Building CE AQ GHG Memo 9-12-22.docx) 20 include architectural coatings, consumer products, and landscaping. Energy -source emissions result from activities in buildings that use electricity and natural gas . Mobile-source emissions are from vehicle trips associated with operation of the project. Area-source emissions consist of direct sources of air emissions at the project site, including architectural coatings, consumer products, and use of landscape maintenance equipment.

PM10 emissions result from running exhaust, tire and brake wear, and t he entrainment of dust into the atmosphere from vehicles traveling on paved roadways. Entrainment of PM10 occurs when vehicle tires pulverize small rocks and pavement an d the vehicle wa kes 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 diesel- powered vehicles.

Energy-source emissions result from activities in buildings that use electricity and natural gas . 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 lowe rs 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.

Long-term operational emissions associated with the proposed project were calculated using CalEEMod. Table E provides the proposed project’s estimated operational emissions. Attachment B provides CalEEMod output sheets.

Note: Some values may not appear to add correctly due to rounding.

The results shown in Table E indicate the proposed project would not exceed the significance criteria for daily VOC, NO x, CO, SOx, PM10, or PM 2.5 emissions. Therefore, operation of the proposed project would not result in a cumulatively considerable net increase of any criteria pollutant for which the project region is in nonattainment under an applicable federal or State AAQS.

9/12/22 (P:\CLB1904.39 Medical Building CE\Technical Studies\AQ GHG\Medical Building CE AQ GHG Memo 9-12-22.docx) 21 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 vicinity of the proposed project site. Localized air quality impacts would occur when emissions from vehicular traffic increase as a result of the proposed project. The primary mobile -source 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, it disperses rapidly with distance from the source. However, under certain extreme m eteorological 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 that future ambient air quality levels be projected. Existing CO concentrations in the immediate project vicinity are not available. Ambient CO levels monitored at the Los Angeles Monitoring Station located at 7201 W. Westchester Parkway (the closest station to the project site) , showed a highest recorded 1-hour concentration of 1.8 ppm (the State standard is 20 ppm) and a highest 8 -hour concentration of

1.3 ppm (the S tate standard is 9 ppm) from 201 9 to 202 1. The highest CO concentrations would normally occur during peak traffic hours; hence, CO impacts calculated under peak traffic conditions represent a worst-case analysis. Reduced speeds and vehicular congestion at intersections result in increased CO emissions.

Health Risk on Nearby Sensitive Receptors
Sensitive receptors are defined as people who ha ve an increased sensitivity to air pollution or environmental contaminants. Sensitive receptor locations include schools, parks and playgrounds, daycare centers, nursing homes, hospitals, and residential dwelling units. As discussed above, the closest sensitive receptors include single family residential uses located approximately 400 feet southwest of the project site. LST analysis was completed to show the construction and operational impacts at 120 meters (400 feet) to the nearest sensitive receptors to the project site in SRA 4, based on a 2-acre project size. Tables F and G show the results of the LST analysis during project construction and operation, respectively.

As detailed in Tables F and G, the emission levels indicate that the project would not exceed SCAQMD LSTs during project construction or operation. The project’s peak operational on-site NOx emissions are less than 1.0 lb/day. Due to the small size of the proposed project in relation to the overall Basin, the level of emissions is not sufficiently high to use a regional modeling program to correlate health effects on a Basin -wide level. On a regional scale, the quantity of emissions from the project is incrementally minor. Because the SCAQMD has not identified any o ther methods to quantify health impacts from small projects and due to the size of the project, it is speculative to assign any specific health effects to small project- related emissions. However, based on this localized analysis, the proposed project woul d not expose sensitive receptors to substantial pollutant concentrations .

Therefore, the project would not expose sensitive receptors to substantial levels of pollutant concentrations.

Therefore, the proposed project would not result in other emissions (such as those leading to odors) adversely affecting a substantial number of people.

Greenhouse Gas Emission 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 p roject’s construction- and operational-related GHG emissions and contribution to global climate change. SC AQMD has not addressed emission thresholds for construction in its CEQA Handbook; however, SCAQMD requires quantification and disclosure. Thus, this section discusses construction emissions.

Construction Greenhouse Gas Emissions . Construction activities associated with the proposed project would produce combustion emissions from various sources. Construction would emit GHGs through the operation of construction equipment and from worker and builder supply vendor vehicles for the duration of the approximately 6-month construction period. The combustion of fossil -based fuels creates GHGs such as CO
2, CH4, and N 2O. Furthermore, the fueling of heavy equipment emits CH4. Exhaust emissions from on -site construction activities would vary d aily as construction activity levels change.

As indicated above, SCAQMD does not have an adopted threshold of significance for construction - related GHG emissions. However, lead agencies are required to quantify and disclose GHG emissions that would occur during construction. The SCAQMD then requires the construction GHG emissions to be amortized over the life of the project, defined as 30 years, added to the operational emissions, and compared to the applicable interim GHG significance threshold tier. Table H shows CO 2e emission calculations for each respective construction phase of the proposed project.

CO2e = carbon dioxide equivalent

As indicated in Table H , it is estimated that the project would generate 67.3 MT of CO2e during construction of the project. When amortized over the 30 -year life of the project, annual emissions would be 2.2 MT of CO2e.

9/12/22 (P:\CLB1904.39 Medical Building CE\Technical Studies\AQ GHG\Medical Building CE AQ GHG Memo 9-12-22.docx) 24 Operational Greenhouse Gas Emissions . Long-term operation of the proposed project would generate GHG emissions from area, mobile, waste, and water sources as well as indirect emissions from sources associated with energy consumption. Mobile -source GHG emissions would include project-generated vehicle trips associated with trips to the proposed project. Area- source emissions would be associated with activities such as landscaping and maintenance on the project site and other sources. Waste source emissions generated by the proposed project incl ude energy generated by landfilling and other methods of disposal related to transporting and managing project -generated waste. In addition, 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 I shows the estimated operational GHG emissions for the proposed project. Motor vehicle emissions are the largest source of GHG emissions for the project at approximately 7 7 percent of the project total. Waste sources are the next largest category at approximately 13 percent. Energy and water sources are about 8 percent and 2 percent of the total emissions respectively. Attachment B provides additional calculation details.

SCAQMD = South Coast Air Quality Management District

As discussed above, a project would have less than significant GHG emissions if it would result in operational-related GHG emissions of less than the scaled SCAQMD threshold of 2,640 MT of CO2e per year. Based on the analysis results, the proposed project would result in 126.0 CO2e per year , which would be below the numeric threshold of 2,640 MT of CO2e per year. Therefore, operation of the proposed project would not generate significant GHG emissions that would have a significant effect on the environment.

Consistency with Greenhouse Gas Reduction Plans
As presented above, the City of Long Beach is currently preparing a CAAP, which includes the CAAP Checklist which would be used for future projects to determine their consistency with the CAAP.

However, since the CAAP has not yet been approved , the proposed project was analyzed for consistency with the goals of AB 32, the AB 32 Scoping Plan, EO B-30-15, SB 32, and AB 197 and SCAG’s 2020–2045 RTP/SCS.

9/12/22 (P:\CLB1904.39 Medical Building CE\Technical Studies\AQ GHG\Medical Building CE AQ GHG Memo 9-12-22.docx) 25 CARB Scoping Plan. As discussed above, California’s major initiative for reducing GHG emissions is AB 32, passed by the State Legislature on August 31, 2006. AB 32 is aimed at reducing GHG emissions to 1990 levels by 2020. AB 32 requires 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 comp liance mechanisms, monetary and nonmonetary incentives, voluntary actions, market-based mechanisms (e.g., cap-and-trade system), and an AB 32 implementation fee to fund the program.

EO B-30-15 added the immediate target of reducing GHG emissions to 40 per cent below 1990 levels by 2030. CARB released a second update to the Scoping Plan, the 2017 Scoping Plan, to reflect the 2030 target set by EO B-30-15 and codified by SB 32. 10 SB 32 affirms the importance of addressing climate change by codifying into statute the GHG emissions reduction target of at least 40 percent below 1990 levels by 2030 contained in EO B-30-15.

SB 32 builds on AB 32 and keeps us 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 CARB related to the adoption of strategies to reduce GHG emissions. Additional direction in AB 197 that is intended to provide easier public access to air emission data collected by the CARB was posted in December 2016.

As identified above, the AB 32 Scoping Plan contains GHG reduction measures that work towards reducing GHG emissions, consistent with the targets set by AB 32, EO 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.

Energy-efficient 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 e nergy 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 ident ified above, the proposed project would comply with the 2019 CALGreen Code standards, regarding energy conservation and green building standards. Therefore, the proposed project would comply with applicable energy measures.

Water conservation and efficienc y 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 be required to comply with the 2019 CALGreen Code standards, 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 Landscap e Ordinance. Therefore, the proposed project would not conflict with any of the water conservation and efficiency measures.

9/12/22 (P:\CLB1904.39 Medical Building CE\Technical Studies\AQ GHG\Medical Building CE AQ GHG Memo 9-12-22.docx) 26 The goal of transportation and motor vehicle measures is to develop regional GHG emission reduction targets for passenger vehicles. Specific regional emission targets for transportation emissions would not directly apply to the proposed project. However, vehicles traveling to the project site would comply with the Pavley II (LEV III) Advanced Clean Cars Program. 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. Therefore, the proposed project would not conflict with the identified transportation and motor vehicle measures.

The proposed project would comply with existing State regulations adopted to achieve the overall GHG emission reduction goals identified in AB 32, the AB 32 Scoping Plan, EO B-30-15, SB 32, and AB 197.

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 throug h 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 more efficiently distribute population, housing, and employment growth, as well as a forecasted development pattern that is generally consistent with regional- level General Plan data. T he 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.

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.

The proposed project would include a 3,000- square-foot medical office building. Due to the size of the proposed proj ect, it is anticipated that implementation of the proposed project would not 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.

9/12/22 (P:\CLB1904.39 Medical Building CE\Technical Studies\AQ GHG\Medical Building CE AQ GHG Memo 9-12-22.docx) 27 CONCLUSION
Based on the analysis presented above, construction and operation of the proposed project would not result in the generation of criteria air pollutants that would exceed SCAQMD thresholds of significance. Compliance with SCAQMD Rule 403: Fugitive Dust would further reduce construction dust impacts. The proposed project is not expected to produce significant emissions that would affect nearby sensitive receptors. The project would also be consis tent with the 2016 AQMP. The project would also not result in objectionable odors affecting a substantial number of people. GHG emissions released during construction and operation of the project are estimated to be minimal and would not be cumulatively considerable. The proposed project would generally be consistent with both the CARB Scoping Plan and the SCAG’s RTP/SCS.
