SUBJECT: APPROVAL OF A ZONE CHANGE, SITE PLAN REVIEW, CONDITIONAL
USE PERMIT, VARIANCE, AND LOT MERGER TO FACILITATE THE
DEVELOPMENT OF A NEW 18,718 SQUARE FOOT YMCA FACILITY (PLN- 23-00168)
EXECUTIVE SUMMARY
The City Council will consider approving a request to construct an 18,718 square-foot YMCA facility on a 2.16-acre site. The applicant’s request includes consideration of a Zone Change, Site Plan Review, Conditional Use Permit, Variance, and Lot Merger. The project proposes changing the zoning classification from Open-Space (O-S) to Commercial Office (C-P) for the property at 11531 Downey Avenue. The zone change is requested as a clean-up item due to inconsistency with the General Plan designation for one of the parcels that is part of the proposed project site.
Staff recommends that the City Council approve the requested applications due to the project’s ability to make all necessary findings.

BACKGROUND
The applicant, Rodrigo Abello, representing the YMCA, submitted the request for the development on May 21, 2024. After subsequent resubmittals and City Staff reviews, the application was deemed complete on July 23, 2024.
The application was heard by the Planning Commission at its regularly scheduled meeting of August 21, 2024. After considering all evidence and testimony provided at the public hearing and following deliberation, a motion to recommend approval to the City Council passed with a 4-0-1 vote.
Additionally, on November 14, 2023, a request to waive City fees associated with the development of the YMCA was heard by the City Council and passed with a 4-0-1 vote.
Site and Location
The 2.16-acre project site is located in central Downey at the southwest corner of Downey Avenue and Arnett Street. The subject property is currently owned and previously operated the YMCA of Los Angeles. The site is currently developed with a 60,927 square- foot YMCA building, and one single-family home. The site is comprised of three parcels (APNs: 6255-013-032, 6255-013-033, and 6255-013-034). Two of the parcel (11521 and 11531 Downey Avenue) currently make up the existing YMCA, and the third parcel (8268 Arnett Street) is an adjoining single-family parcel purchased to facilitate the development of the new YMCA facility. The buildings were constructed from 1947 to 1965, and no major renovations have taken place since that time. Lastly, the YMCA facility is currently vacant and previously operated from 1965 – 2020.
The properties directly to the north and east are also zoned CP and developed with professional offices, medical offices, legal nonconforming single-family residences, and a parking lot. The properties directly to the west are zoned Single-Family Residential (R-1) and developed with single-family homes. Lastly, the property directly to the south is zoned Multifamily Residential (R-3) and developed with apartments.

ANALYSIS
Zone Change
The project includes a request to amend the Zoning designation for the property located at 11531 Downey Avenue (APN 6255-013-032) from the Open Space (OS) zone to the Professional Office (CP) zone. The request is needed in order to correct inconsistencies between the City’s Zoning Map and General Plan Designation Map. The General Plan Designation for all three subject properties is Office (O). The corresponding appropriate land use zoning designation for the General Plan designation of Office is the CP zone.
The request is a corrective matter and does not bestow any special privilege upon the property that would not otherwise be permissible in the current zoning designation.
Existing Zoning Proposed Zoning
Figure D – Existing and Proposed Zoning Designation
Site Plan Review
The changes to the existing site include the demolition of 53,302 square feet of the existing building and preservation of an existing 7,625 square foot gymnasium. The proposed new development would consist of an 18,718 square-foot, 27-foot-high YMCA recreational use facility. The site would be developed with various buildings with the following components: office space, swimming pool, fitness center, multipurpose room, basketball gymnasium, restrooms, locker rooms, and storage area.

The existing gymnasium to the rear of the property would maintain its existing red brick masonry aesthetic with accent concrete columns.
Figure D – Rendering of Building Entrance (left) and Downey Street Frontage (right)
Access, Circulation, and Parking
The site is accessible from two frontages, on Downey Avenue and Arnett Street, with one driveway opening on each street frontage. Both driveway openings are 26’ wide. The drive aisle widths surrounding the building and in the parking lot are no less than 26’ wide, which allows for maneuvering throughout the site for emergency vehicles.
The site would accommodate 93 standard parking spaces and 5 compact spaces.
Amongst the parking spaces, there will be accessible parking spaces and electric vehicle charging spaces. The parking provided complies with the requirements of the Downey Municipal Code (DMC) and is detailed in Table 1 of this report.
Conditional Use Permit
A CUP for the YMCA facility is required due to the proposed land use classification. As described by the applicant, proposed activities to occur onsite include: Sports and Teen Leadership programs, Academic Enrichment and Support, Water Safety and Drowning Prevention for children, teens, and adults, and healthy lifestyle programs for mind, body, and spirit for all ages. Added activities include pickle-ball and basketball, as well as sporting competitions.
Agenda Page 6
YMCA – KOLAR FAMILY YMCA OF DOWNEY
SEPTEMBER 24, 2024
PAGE 7
The YMCA facility would have approximately 100 employees to operate the site and up to 10 employees present at any given time. The hours of operation are noted below in Table 3.
Table 3
Hours of Operation
Monday - Friday 6:00 am – 9:00 pm
Saturday 8:00 am – 4:00 pm
Sunday 12:00 pm – 5:00 pm
Variance
The proposed variance is a request to deviate from DMC Section 9410.12(c). The variance is requested in order to retain the gymnasium structure in its current legal non- conforming location with a rear setback of 13.33’ (feet) and height of 25.83’ (feet). Strict compliance with the code would otherwise mean that the structure relinquishes all legal nonconforming privileges and requires that a larger portion of the existing structure be demolished to accommodate a required 46’ (foot) rear setback.
A variance request is prompted due to the amount of proposed demolition of the existing structure. In summary, DMC section 9410.12(c) allows the continuance of legal nonconformities when less than 50% of a structure is being demolished. In this particular case, the project proposes the demolition of 53,302 square feet which constitutes roughly
87.5% of the existing structure. Therefore, the existing structure is required to comply with all current development standards and may not retain a 13.33’ rear setback or height of
25.83’.
The variance is deemed necessary because the existing YMCA facility presents a unique circumstance related to how the site is operated and was constructed. The existing YMCA facility appears to be one structure because all of its separate components are attached.
However, the overall facility presents a unique circumstance because various portions of its structure rely on completely independent structural and architectural components.
Unlike a traditional structure, the gymnasium is more so built as a separate abutting structure. The gymnasium is completely enclosed and sustained by its own individual walls and foundation. In addition, the gymnasium could remain in place without any support from surrounding structures or retrofitting. Therefore, because the gymnasium can stand independently, it is reasonable to determine that it is a separate structure from the rest of the overall YMCA building. In this case, the gymnasiums’ setback may be granted, through a variance, with the same legal nonconforming rights granted to detached standalone structures. If the gymnasium were completely detached, then DMC Section 9410.12(c) would not apply, and the structure would be able to remain in place by right. Therefore, once again the particular way in which the structure was designed Agenda Page 7
YMCA – KOLAR FAMILY YMCA OF DOWNEY
SEPTEMBER 24, 2024
PAGE 8
and built presents a unique circumstance that supports the approval of the requested variance.
Lot Merger
The applicant proposes the consolidation of three separate Assessor’s Parcel Numbers (6255-013-032, 6255-013-033, AND 6255-013-034). The combined area of the lots is
2.16 acres. The parcels are legally established and can be found as Parcels 1, 2, 3, 4 and 5 as recorded in Deed Book 1, Pages 156 and 158. The parcels are also identified as lots 32, 33, and 34 in the assessor’s book number 6255 Page 13 of the County of Los Angeles. The proposed legal description and map are provided in Attachment H of this report.
California Environmental Quality Act
The City reviewed the environmental impacts of the proposed project pursuant to California Environmental Quality Act (CEQA). It was determined that this request is categorically exempt from CEQA, pursuant to Guideline Section No. 15332 (Class 32 – In-fill Development Projects). Class 32 exemptions consist of projects in urban areas on lots equal to or less than 5 acres and that do not present any potential to produce an environmental impact.
A series of technical studies were submitted to support the above environmental determination. The studies find that the project will not produce any significant impact related to Noise, Air Quality and Greenhouse Gas Emissions, Cultural Resources, and Traffic. The studies are provided in this report as Attachment I, Exhibits B-F.
Public Comment
As of the preparation of this report, staff received written correspondence from one individual requesting that the existing red curb along the south bound lane of Downey Avenue at the intersection of Downey Avenue be extended to increase visibility for drivers making right turns. A copy of the public comment is included in Attachment K.
PROJECT TIMELINE
The YMCA facility construction is anticipated to begin in October of 2024 with a grand opening tentatively scheduled for April 2026.

AN ORD INANCE OF THE CITY COUNCIL OF THE CITY OF DOWNEY
APPROVING A ZONE CHANGE DESIGNATION FROM O-S (OPEN SPACE) TO C-P (OFFICE) FOR THE PROPERTY LOCATED AT 11531 DOWNEY AVENUE WHEREAS, on May 21, 2024, the applicant, Rodrigo Abello (a representative of YMCA of Los Angeles), formally submitted a request for a Zone Change, Site Plan Review, Conditional Use Permit, Variance, and Lot Merger, to construct a new 18,718 square foot YMCA parks and recreational facility at 11521 Downey Avenue, 11531 Downey Avenue, and 8268 Arnett Street (“Project”); and
WHEREAS , on June 21, 2024, the applicant was issued a letter deeming the application incomplete; and
WHEREAS , on July 23, 2024, upon review of all required materials submitted, the applicant was issued a letter deeming the application complete; and WHEREAS, on August 8, 2024, notices of a Planning Commission public hearing for a Zone Change, Site Plan Review, Conditional Use Permit, Variance, and Lot Merger were sent to all tenants and property owners within 500 feet of the subject site, and the public hearing notice was published in Downey Patriot; and,
WHEREAS, the Planning Commission held a duly noticed public hearing on August 21 , 2024, and after fully considering all oral and written testimony, facts, and opinions, adopted Resolution No. 24-4035 recommending approval of a zone change to the City Council for the Project, as well as Resolution 24-4036 recommending approval of a Site Plan Review, Conditional Use Permit, and Variance, and Resolution 24-4037 recommending approval of a Lot Merger; and WHEREAS, the City Council held a duly noticed public hearing on September 24, 2024, to fully consider all oral and written testimony and facts and opinions regarding the Zone Change, Site Plan Review, Conditional Use Permit, Variance, and Lot Merger.
NOW, THEREFORE, THE CITY COUNCIL OF THE CITY OF DOWNEY, CALIFORNIA, DOES HEREBY ORDAIN AS FOLLOWS:
SE CTION 1. The City Council of the City of Downey hereby finds, determines, and declares as follows:
A.The zone change for the Project is necessary and desirable for the development of the community in harmony with the objectives of the General Plan and Chapter 8 of Article IX of the Downey Municipal Code and is in the interests or furtherance of the public health, safety, and general welfare. The City Council adopted a comprehensive update to the General Plan on January 25, 2005, which identifies the subject property within the designation of Office (O). The current zoning for the property is designated as Open Space (O-S), which is not the corresponding zoning for the General Plan Designation of Office.
The zone change from O-S to C-P (Commercial Office) will make the zoning for the site consistent with the General Plan. Furthermore, the zone change for this property does not grant the subject property any added liberties it did not previously already have. Therefore, with this action there is no opportunity to negatively affect the public health, safety, or general welfare of the community.
Attachment B
Agenda Page 12
ORDINANCE NO.
PAGE 2
B. The zone change will be compatible and complementary to existing conditions and adjoining property in the surrounding area. Nearby commercially developed properties along Downey Avenue are appropriately zoned C-P. The in tent of the zone change is to remove the inconsistent O-S zone and provide a compatible zoning designation of C-P.
This is ultimately compatible with the existing and proposed use on the subject property.
It is also compatible with the surrounding area, as nearby properties located to the North and East along Downey Avenue are also zoned C-P and developed with commercial office uses.
C. The site is adequate in size to accommodate the uses permitted in the requested zone and complies with all applicable property development standards. The 2.16-acre site is substantially greater than the minimum required lot size of 6,000 square feet for the C-P zone. The minimum lot size is established in part to ensure sites can appropriately meet development standards and accommodate allowed uses. Furthermore, the proposed development filed in conjunction with the zone change request will comply with all applicable development standards.
D. The site properly relates to streets and highways designed and fully improved to carry the type and quantity of traffic that is expected to be generated in the area, and utilities exist or are planned which will adequately serve the property as rezoned. Changing the zoning from O -S to C-P does not bestow upon the property an opportunity to develop the site in a way that would not otherwise be allowed in either zoning designation. Therefore, the adjoining road segments were intended to serve developments such as the proposed new YMCA facility. In addition, the proposed development request filed in conjunction with this zone change request is smaller in size than the original YMCA facility proposed to be demolished. The new development will incorporate more efficient circulation within the lot and egress and ingress for the site. Lastly, per a traffic analysis conducted for the new YMCA facility, the project is anticipated to produce a net decrease of 608 daily vehicles trips. Therefore, level of service for nearby road segments will not be altered.
E. The proposed zone change is in general conformance with the General Plan and General Plan land use designation for the parcel. The Zone Change to C-P will align the zoning map with the appropriate corresponding General Plan Designation of Office (O).
SECTION 2. The City Council further finds, determines and declares that the proposed project was reviewed for compliance with the California Environmental Quality Act (CEQA), and is categorially exempt from CEQA, pursuant to CEQA Guidelines Section 15332 (Class 32 – In- fill Development Projects). Class 32 exemptions consist of projects characterized as in-fill development meeting the following conditions: the project is consistent with the applicable general plan and zoning designations; the proposed development occurs within city limits on a site of no more than 5 acres substantially surrounded by urban uses; the project site has no value as habitat for endangered, rare, or threatened species; approval of the project would not result in any significant effects relating to traffic, noise, air quality, or water quality; and the site can be adequately served by all required utilities and public services.
SECTION 3. Based on the findings set forth in Section 1 and Section 2 of this Ordinance, the City Council hereby determines property located at 11531 Downey Avenue is hereby rezoned from O-S (Open Space) to C-P (Professional Office), as outlined in Exhibit ‘A’ of this Ordinance.
SECTION 4. If any section, subsection, sentence, clause, phrase or portion of this Ordinance is for any reason held to be invalid or unconstitutional by the decision of any court of competent jurisdiction, such decision shall not affect the validity of the remaining portions of this Attachment B

ordinance. The City Council of the City of Downey hereby declares that it would have adopted this ordinance and each section, subsection, sentence, clause, phrase or portion thereof irrespective of the fact that any one or more sections, subsections, sentences, clauses, phrases, or portions be declared invalid or unconstitutional.
SECTION 5. This Ordinance shall become effective thirty (30) days after its adoption.

WHEREAS, the Planning Commission held a duly noticed public hearing on August 21, 2024, and after fully considering all oral and written testimony, facts, and opinions, adopted Resolution No. 24-403 6 recommending approval of a Site Plan Review, Conditional Use Permit, and Variance by the City Council for the Project, as well as Resolution 24-4035 recommending approval of a Zone Change and Resolution 24-4037 recommending approval of a Lot Merger; and
WHEREAS, the City Council held a duly noticed public hearing on September 24, 2024, to fully consider all oral and written testimony and facts and opinions regarding the Zone Change, Site Plan Review, Conditional Use Permit, Variance, and Lot Merger.
NOW, THEREFO RE, THE CITY COUNCIL OF THE CITY OF DOWNEY, CALIFORNIA, DOES HEREBY RESOLVE AS FOLLOWS:
SE CTION 1. The City Council of the City of Downey hereby finds, determines, and declares as follows regarding the Site Plan Review:
A.The site plan is consistent with the goals and polices embodied in the General Plan and other applicable plans and policies adopted by the City Council. The proposed YMCA parks and recreational facility is in harmony and does not adversely affect the goals and policies outlined in the City’s General Plan. In addition, the project’s objective to revitalize the site helps achieve various long-term goals. Specifically, the following policies are promoted by the proposed development:
Policy 1.1.1 – Maintain a Balance of Land Uses
Program 9.1.1.5 – Continue the revitalization of commercial and industrial Attachment C
Agenda Page 16
Resolution No. 24 -8269
corridors.
The site is located within a commercial general plan designation and was originally developed between the years of 1947 and 1965. The new proposed parks and recreational facility will revitalize the site with a new contemporary building, landscaping, and improved vehicular circulation, which will improve the overall aesthetic of the subject property.
Policy 1.1.3 – Provide and appropriate amount of land area for business and employment.
Program 1.1.3.1 – Encourage land uses that generate jobs.
Policy 9.2.1 – Promote job-generating land uses.
Program 9.2.1.3 – Promote employment that increases the daytime population of the city creating customer demand for other businesses.
Program 9.2.2.1 – Promote a diversified employment base with jobs in sectors in addition to retail sales.
The project is anticipated to create 100 permanent jobs.
City Value – To provide excellent housing, educational, employment, and recreational
opportunities.
Program 1.1.5.3 – Promote recreation and entertainment uses that serve needs of the
public.
The site plan promotes the above policies by introducing a unique commercial recreation facility within the city, and adds to the amount of recreational options available to residents.
Goal 6.1 – Protect persons from exposure to excessive noise.
Policy 6.1.1 – Minimize noise impacts onto noise-sensitive uses.
Program 6.1.1.2 – Ensure that new developments within areas with exterior noise at unacceptable levels are designed to maintain interior noise levels at acceptable levels.
Goal 6.3 – Minimize noise impacts on noise-sensitive land uses.
Policy 6.3.1 – Minimize the amount of noise generated by land uses.
Program 6.3.1.1 – Discourage proposed land uses from generating noise at [un]acceptable levels.
As part of the project, a Noise Study identified that the development while in operation, will not generate noise beyond the levels allowed within the Downey Municipal Code.
Noise levels generated by temporary construction and long-term operations will not exceed the City’s noise ordinance. Construction activity is expected to produce noise at a maximum level of 78.8 dBA. The DMC restricts construction noise to between 7:00 a.m. and 9:00 p.m., with a maximum level of 85 dBA at property boundaries.
Attachment C
Agenda Page 17
Resolution No. 24 -8269
Long term operational noise will occur from the pickleball court, rooftop air conditioning units, and vehicle noise from the parking lot. Operational noise levels will peak at 47.8 dBA during the day and 43.0 dBA at night. The DMC restricts noise in proximity to residential zones to a maximum of 55 dBA during the day, and 45 dBA at night. Additionally, in an effort to control noise, the Project will feature a 10-foot Acoustifence around the pickleball court and will close it at night.
Goal 8.1 – Promote quality design for new, expanded, and remodeled Construction.
Policy 8.1.1 – Promote architectural design of the highest quality.
Program 8.1.1.1 – Discourage construction with architectural design of poor quality.
Goal 8.3 – Promote the enhancement of the streetscape.
Policy 8.3.1.1 – Enhance the views of property from the public streets to exhibit a positive image.
Program 8.3.1.1 – Promote prevailing street yard setbacks for buildings consistent with adjacent properties.
Program 8.3.1.2 – Maximize the landscaped setback on street yard Setbacks.
The proposed architecture is a significant upgrade to the existing vacant parks and recreational facilities on site and is compatible with surrounding properties. The proposed project would be newer than most developments within its proximity in regard to proposed quality of design, site layout, and landscaping. The site has remained relatively the same since 1965 and is surrounded by a mix of older single-family, multi-family, and commercial properties. The redevelopment of this site can serve as an example of higher quality architecture for future developments within the city, and directly enhances the surrounding area.
B. The proposed development is in accordance with the purposes and objectives of Article IX of the Downey Municipal Code (Land Use) and the zone in which the site is located. The purpose of the C-P (Commercial Office) zone, as stated in the Downey Municipal Code, “is intended to provide for the development of integrated office and professional areas wherein related types of uses and facilities may also be located. The provisions of this zone are intended to encourage the most desirable relationship of permitted uses and to provide a transition between more intensive commercial activities and residential areas.” The proposed YMCA parks and recreational facility aims to provide a service to the community, and in particular nearby residential properties. In addition, the proposed facility will operate from 6:00 am – 9:00 pm on weekdays, 8:00 am – 4:00 pm on Saturdays, and 12:00 pm – 5:00 pm on Sundays. These hours are compatible with nearby residential uses. Therefore, the proposal application is found to be in conformance with the purpose statement above.
C. The proposed development’s site plan and its design features, including architecture and landscaping, will integrate harmoniously and enhance the character and design of the site, the immediate neighborhood, and the surrounding areas of the City. The proposed design of the project will integrate harmoniously with the surrounding area by providing aesthetically pleasing architecture and landscaping. The proposed 18,718 square foot building will serve as a significant Attachment C
Agenda Page 18
Resolution No. 24 -8269
upgrade from the existing facility on the site and nearby community. In addition, the streetscape will be enhanced as well as the transition from the street onto the site through the proposed landscaping and upgraded vehicle approaches.
D. The site plan and location of the buildings, parking areas, signs, landscaping, luminaries, and other site features indicate that proper consideration has been given to both the functional aspects of the site development, such as automobile and pedestrian circulation, and the visual effects of the development from the view of the public streets. The project design incorporates the DMC required amount of parking and landscaping, including quantity of parking, quantity of trees, landscaping square footage, setbacks, parking stall dimensions, and ADA parking.
In addition, the driveway approaches and on-site drive-aisles are 26’ wide and provide adequate amount space for emergency vehicles to maneuver throughout the lot. Lastly, the photometric plan proposed for this project shows that all parts of the site will be well illuminated while simultaneously not causing any nuisance to the neighboring properties or public right-of-way. Therefore, it is determined that proper consideration has been given to the functional aspects and visual effects of the development.
E. The proposed development will improve the community appearance by preventing extremes of dissimilarity or monotony in new construction or in alterations of facilities. The proposed project reflects true contemporary style architecture and keeps with a scale consistent of smaller scale commercial development. The height and size of structure will be significantly smaller than the current structure on site. The proposed architectural style utilizing various types of materials, glazing, colors, and multiple roof heights is neither dissimilar nor monotonous from other buildings in the area, and this project will upgrade the overall appearance of the site and, in turn, improve the community appearance. This proposed development elevates the quality of design of all commercial properties within the City.
F. The site plan and design considerations shall tend to upgrade properties in the immediate neighborhood and surrounding areas with an accompanying betterment of conditions affecting the public health, safety, comfort, and welfare. The proposed architecture is a significant upgrade to the existing facilities on site and is compatible with surrounding properties although it will be newer than most developments within its proximity. In addition, the redevelopment of this site has the potential to serve as an example of higher quality architecture for future non- residential development within the City of Downey. Lastly, the operational procedures of the proposed development are also conditioned in an effort to ensure that any potential effects in public health, safety, comfort and general welfare are mitigated as much as possible.
G. The proposed development’s site plan and its design components will include graffiti-resistant features and materials in accordance with the requirements of Section 4960 of Chapter 10 of Article IV of the Downey Municipal Code. The project has been conditioned to meet the requirements specified in Section 4960 of the Downey Municipal Code. Section 4960 discusses the installation of anti-graffiti materials and the appropriate allotted time limit for the removal of graffiti.

SECTION 2. The City Council of the City of Downey hereby further finds, determines, and declares as follows regarding the Conditional Use Permit:
A. The requested Conditional Use Permit will not adversely affect the intent and purpose of Article IX of the Downey Municipal Code (Land Use) or the City's General Plan or the public convenience or general welfare of persons residing or working in the neighborhood thereof. The project is consistent with all applicable goals and policies specified in the City’s General Plan, as well as policies stated in the Downey Municipal Code. Environmental assessments conducted for the project indicate the project will not produce impacts, as they relate to Noise, Air Quality and Greenhouse Gas Emissions, Cultural Resources, and Traffic. The subject site is able to meet the parking demands of the proposed use, thus no parking impacts are expected. In addition, the owners also own an adjacent parking lot that is intended to be utilized for additional parking. The project helps achieve long term goals within the City’s General Plan by providing additional recreational services to the community. The following policies are promoted by the proposed CUP:
City Value – To provide excellent housing, educational, employment, and recreational
opportunities.
Program 1.1.5.3 – Promote recreation and entertainment uses that serve needs of the public.
The CUP promotes the above policies by preserving a unique parks and recreational facility that was previously present within the city from 1965 to 2020, and will continue to contribute to the amount of recreational options available to residents.
B. The requested use will not adversely affect the adjoining land uses and the growth and development of the area in which it is proposed to be located. The proposed use will be compatible with, and intends to compliment, other uses within the nearby commercial and residential areas. Parks and recreational facilities are common found near residential properties and intend to directly serve the adjacent community. In addition, it is anticipated the use will not adversely affect surrounding properties because the use, and conditions applicable to the use, can be classified as a less intensive use than others allowed in commercial zones. The intensity, or lack of, is ideal for the Commercial Office (C-P) zone in that it creates a buffer between sensitive uses and larger more instance commercial uses.
Conditions of approval have been incorporated in an effort to ensure compatibility with existing and future uses, as well as mitigate any potential impacts.
C. The size and shape of the site proposed for the use is adequate to allow the full development of the proposed use in a manner not detrimental to the particular area. The request for the proposed scope of work does not include changes to any lots outside of the subject site, or work required in the public right-of -way. In addition, the proposed use is in compliance with the Downey Municipal Code, including adequate parking requirements. The proposed work does not create alterations that would restrict an existing use located within the nearby area from continuing to use their property as currently developed, and does not restrict those properties from altering their structures or operations. Lastly, the new use will Attachment C
Agenda Page 20
Resolution No. 24 -8269
decrease in overall size in comparison to the previous use on site. Therefore, the size and shape of the site proposed for the use is adequate to allow the full development of the proposed use in a manner not detrimental to the particular area.
D. The traffic generated by the proposed use will not impose an undue burden upon the streets and highways in the area. A traffic analysis conducted as part of the requirements for the project found that the project would produce a net decrease of 608 daily vehicles trips. This means that the level of service for nearby road segments will not be altered, and no undue burdens to nearby streets or highways will occur as a result of the project.
SECTION 3. The City Council of the City of Downey hereby further finds, determines, and declares as follows regarding the Variance:
A. Exceptional or extraordinary conditions or circumstances exist which are peculiar to the land, structure, or building involved and which are not generally applicable to other lands, structures, or buildings in the same vicinity and zone. The YMCA facility presents a unique circumstance related to how the site is operated and was constructed. The existing YMCA facility appears to be one structure because all of its separate components are attached. However, the overall facility presents a unique circumstance because various portions of its structure rely on completely independent structural and architectural components. Unlike a traditional structure, the gymnasium is more so built as a separate abutting structure. The gymnasium is completely enclosed and sustained by its own individual walls and foundation. In addition, the gymnasium could remain in place without any support from surrounding structures or retrofitting. Therefore, because the gymnasium can stand independently, it is reasonable to determine that it is a separate structure from the rest of the overall YMCA building. In this case, the gymnasiums’ setback may be granted, through a variance, with the same legal nonconforming rights granted to detached standalone structures. If the gymnasium were completely detached, then DMC Section 9410.12(c) would not apply and the structure would be able to remain in place by right. Therefore, once again the particular way in which the structure was designed and built presents a unique circumstance that supports the approval of the requested variance.
B. The literal interpretation of the provisions of Article IX of the Downey Municipal Code (Land Use) would deprive the applicant of rights under the terms of this article commonly enjoyed by other properties in the same vicinity and zone in which the property is located. The direct request is for the YMCA gymnasium to be granted to retain its current legal nonconforming rights, the same rights applicable to detached structures. If the gymnasium were completely detached. then DMC Section 9410.12(c) would not apply and the structure would be able to remain in place by right. The particular way in which the structure was designed and built presents a unique circumstance that supports the approval of the requested variance. Much like a detached structure, the gymnasium is completely enclosed and sustained by its own individual walls and foundation. The gymnasium could remain in place without any support from surrounding structures or retrofitting.
Therefore, approval of the variance would allow the gymnasium the same privileges commonly enjoyed by other properties with detached structures.
Attachment C
Agenda Page 21
Resolution No. 24 -8269
C. Exceptional or extraordinary conditions or circumstances do not result from the actions of the applicant. The YMCA gymnasium was constructed in 1965 under the applicable development standards at the time. At that time, the developer could not have known that the gymnasium would need to be demolished under future development standards in order to upgrade the site. Therefore, the exceptional or extraordinary circumstances are not reasonably due to the actions of the applicant.
D. Granting the Variance requested will not confer on the applicant any special privilege that is denied by Chapter 8 of Article IX of the DMC to other lands, structures, or buildings in the same vicinity and zone in which the property is located. It is assumed that all similar structures, with equal characteristics, would make the same request in order to preserve a structure that can structurally stand and operate independently from other abutting structures.
Unlike a traditional structure, the gymnasium is built much like a separate abutting structure. The gymnasium is completely enclosed and sustained by its own individual walls and foundation. The gymnasium could remain in place without any support from surrounding structures or retrofitting. Therefore, because the gymnasium can stand independently it is reasonable to determine that it is a separate structure from the rest of the overall YMCA building. In this case, the gymnasiums’ setback and height may be granted, through a variance, the same legal nonconforming rights granted to detached standalone structures in other lands, structures, or buildings in the same vicinity and zone.
E. The granting of a Variance will be in harmony and not adversely affect the General Plan of the City. The proposed facility is in harmony and does not adversely affect the goals and policies outlined in the City’s General Plan. Furthermore, the continuation of nonconforming setbacks and height for the gymnasium does not directly, or inadvertently, contradict any of the aforementioned goals and policies.
Alternatively, the facility in general will promote the following:
Policy 1.1.1 – Maintain a Balance of Land Uses
Program 9.1.1.5 – Continue the revitalization of commercial and industrial corridors.
The site is located within a commercial general plan designation and was originally developed between the years of 1947 and 1965. The new proposed parks and recreational facility will revitalize the site with a new contemporary building, landscaping, and improved vehicular circulation which will improve the overall aesthetic of the subject property.
Policy 1.1.3 – Provide and appropriate amount of land area for business and employment.
Program 1.1.3.1 – Encourage land uses that generate jobs.
Policy 9.2.1 – Promote job-generating land uses.
Program 9.2.1.3 – Promote employment that increases the daytime population of the city creating customer demand for other businesses.
Program 9.2.2.1 – Promote a diversified employment base with jobs in sectors in addition to retail sales.
The project is anticipated to create 100 permanent jobs.

Resolution No. 24 -8269
City Value – To provide excellent housing, educational, employment, and recreational
opportunities.
Program 1.1.5.3 – Promote recreation and entertainment uses that serve needs of the
public.
The Variance promotes the above policies by introducing a unique recreation facility within the city, and adds to the amount of recreational options available to residents and mall patrons.
Goal 6.1 – Protect persons from exposure to excessive noise.
Policy 6.1.1 – Minimize noise impacts onto noise-sensitive uses.
Program 6.1.1.2 – Ensure that new developments within areas with exterior noise at unacceptable levels are designed to maintain interior noise levels at acceptable levels.
Goal 6.3 – Minimize noise impacts on noise-sensitive land uses.
Policy 6.3.1 – Minimize the amount of noise generated by land uses.
Program 6.3.1.1 – Discourage proposed land uses from generating noise at [un]acceptable levels.
As part of the project, a Noise Study identified that the development while in operation, will not generate noise beyond the levels allowed within the Downey Municipal Code.
Noise levels generated by temporary construction and long-term operations will not exceed the City’s noise ordinance. Construction activity is expected to produce noise at a maximum level of 78.8 dBA. The DMC restricts construction noise to between 7:00 a.m. and 9:00 p.m., with a maximum level of 85 dBA at property boundaries.
Long term operational noise will occur from the pickleball court, rooftop air conditioning units, and vehicle noise from the parking lot. Operational noise levels will peak at 47.8 dBA during the day and 43.0 dBA at night. The DMC restricts noise in proximity to residential zones to a maximum of 55 dBA during the day, and 45 dBA at night. Additionally, in an effort to control noise, the Project will feature a 10-foot Acoustifence around the pickleball court and will close it at night.
Goal 8.1 – Promote quality design for new, expanded, and remodeled Construction.
Policy 8.1.1 – Promote architectural design of the highest quality.
Program 8.1.1.1 – Discourage construction with architectural design of poor quality.
Goal 8.3 – Promote the enhancement of the streetscape.
Policy 8.3.1.1 – Enhance the views of property from the public streets to exhibit a positive image.
Program 8.3.1.1 – Promote prevailing street yard setbacks for buildings consistent with adjacent properties.
Program 8.3.1.2 – Maximize the landscaped setback on street yard Attachment C

Setbacks.
The proposed architecture is a significant upgrade to the existing vacant parks and recreational facilities on site and is compatible with surrounding properties. The proposed project would be newer than most developments within its proximity in regard to proposed quality of design, site layout, and landscaping. The site has remained relatively the same since 1965 and is surrounded by a mix of older single-family, multi-family, and commercial properties. The redevelopment of this site can serve as an example of higher quality architecture for future developments within the city, and directly enhances the surrounding area.
F. The reasons set forth in the application justify the granting of the variance and the variance is the minimum variance that will make possible the reasonable use of the land, building, or structure. The main reason is that the design and operation of the gymnasium resembles a detached structure. Detached structures would not be subject to the provisions of Downey Municipal Code Section 9410.12(c), and would be allowed by-right to maintain their legal nonconforming status. As the YMCA gymnasium shares many of the same characteristics as a separate standalone detached structure, it is justified for the gymnasium to be granted the same legal nonconforming rights.
SECTION 4. The City Council further finds, determines and declares that the proposed project was reviewed for compliance with the California Environmental Quality Act (CEQA), and is categorially exempt from CEQA, pursuant to CEQA Guidelines Section 15332 (Class 32 – In- fill Development Projects). Class 32 exemptions consist of projects characterized as in-fill development meeting the following conditions: the project is consistent with the applicable general plan and zoning designations; the proposed development occurs within city limits on a site of no more than 5 acres substantially surrounded by urban uses; the project site has no value as habitat for endangered, rare, or threatened species; approval of the project would not result in any significant effects relating to traffic, noise, air quality, or water quality; and the site can be adequately served by all required utilities and public services. .
SECTION 5. Based upon the findings set forth in Sections 1 through 4 of this Resolution, the City Council hereby approve s the Site Plan Review, Conditional Use Permit, and Variance (PLN-23-00168 ) for the Project, subject to conditions of approval attached hereto as Exhibit ‘A’, which are necessary to preserve the health, safety, and general welfare of the community and enable the City Council to make the findings set forth in the previous sections. The conditions are fair and reasonable for the accomplishment of these purposes.

Resolution No. 24 -8270
B. Development of the merged parcel creates no public health, safety or welfare hazards. The lot merger will assist in facilitating the redevelopment of the site with a small newer facility of the same use and function. All potential impacts are expected to either be reduced or equal compared to existing impacts present while the current vacant YMCA recreation facility was in operation. Lastly as evidence to the support a Class 32 CEQA exemption, the overall redevelopment of the site underwent technical studies related to Noise, Air Quality and Greenhouse Gas Emissions, Cultural Resources, and Traffic. The studies find that no impacts will be generated as a result of the redevelopment of the site. Therefore, it is further found that the merged parcels and final development will not create hazards to public health, safety, or welfare.
C. The merged parcel has adequate access and is served by all necessary utilities.
The proposed parcel will have access from two separate street frontages along Downey Avenue and Arnett Street. Maneuvering onto and out of the site is achieved through two (2) separate 26’ (foot) driveways allowing adequate access to emergency vehicles. Utilities including, but not limited to, cable, phone, internet, and electricity are currently existing on site and accessed from utility poles found along both street frontages.
D. The merged parcel is comprised of legally created standard parcels, owned in common by the same person(s). The parcels are recorded with the County of Los Angeles and identified in Parcel Map No. 6255, Page 13, as Parcels 32, 33, and 34, and are all owned by YMCA of Los Angeles.
E. The merged parcel does not require right-of-way or utility easement dedications, as none are proposed for this project and are not currently located on site to provide the current utilities to the existing site.
F. The merged parcel does not require parking or access agreements. All parking is contained on site and in compliance with the standards outlined in the Downey Municipal Code.
SECTION 2.

YMCA of Metropolitan Los Angeles (“Project Applicant”) seeks to redevelop an approximately 2.16-acre property located northwest of Downey Avenue, south of Firestone Boulevard, and east of Paramount Boulevard in the City of Downey (“City”), County of Los Angeles. The subject property’s Assessor’s Parcel Numbers (APNs) are 6255- 013-032, -033, and -034 (“Project site”). The Project site is currently developed with four (4) existing structures totaling approximately 61,756 square feet (sf).
As part of the Project, the majority of existing structures would be demolished. The existing 7,625 sf basketball gymnasium would remain and be remodeled as part of the Project. Additionally, the Project proposes the construction of a new approximately 18,808 sf gymnasium and 975 sf lobby/restroom area. The new gymnasium would include amenities such as fitness areas, locker rooms, kitchen and office areas, and an indoor pool. New landscaping would be installed around the perimeter of the site.
Figure I-1 illustrates the areas of the site to be demolished. Figure I-2 presents the proposed Site Plan.
The information presented in this Memorandum is based on our review and analysis of the following documents and information: (a) materials provided by the Project Applicant regarding the proposed Project; (b) publicly available documents and information from the City of Downey website, including but not limited to the City’s General Plan, Zoning and Land Use Code, and (c) information provided by the City of Downey staff.

II. EXISTING CONDITIONS
A. Existing Land Use
The Project site consists of three (3) lots totaling 94,185 sf/2.16 acres located at 11531 Downey Avenue in the City of Downey. All three lots are under the common ownership of the Applicant. The subject site is developed with one recreational building (built 1963), one commercial building (built 1965), and one single-family residence with detached garage (built between 1947 and 1950) totaling approximately 61,756 sf.
B. Existing General Plan Designation
The City of Downey General Plan designates the Project site as Office (O). The Office (O) land use designation allows for professional and medical office uses. The intensity of the Office designation should fall within a range of floor area ratio between 0.5:1 and 5:1. The Project is consistent with the City’s General Plan land use designation of Office (O).
C. Existing Zoning
The Project site is located within the Commercial – Professional Office (C-P) zone and Open Space (O-S) zone. APN 6255-013-032 is zoned O-S and APNs 6255-013-033 and 6255-013-034 are zoned C-P.
The C-P Zone is intended to provide for the development of integrated office and professional areas wherein related types of uses and facilities may also be located. The provisions of this zone are intended to encourage the most desirable relationship of permitted uses and to provide a transition between more intensive commercial activities and resident ial areas.
The O-S Zone is intended to prevent incompatible development in areas that should be preserved or regulated for scenic, recreational, conservation, aesthetic, or health and safety purposes. The O-S Zone may also provide for permanent open space in the community by limiting development in areas which may contain geological features that may affect the structural use of the site.
According to Downey Municipal Code (DMC) §9314.04, recreational facilities could be allowed in the C-P Zone through the issuance of a Conditional Use Permit (CUP). Recreational facilities are permitted under the O -S Zone according to DMC §9322.04. Development standards for properties within the C-P and O-S Zone are provided for in DMC §9314 and §9322, respectively. The Project is consistent with the C-P and O-S zoning.

D. Surrounding Land Uses
Surrounding land uses include residential and office uses within the City of Downey limits. Specifically, the Project site is surrounded by single-family residences to the north; multi-family residences to the south; offices to the east; and single-family residences to the west. Surrounding land uses are zoned R-1 to the north and west; R-3 to the south; and C-P to the east. The Project is consistent with the General Plan and zoning and, therefore, would complement surrounding development.
III. CEQA CATEGORICAL EXEMPTION
A. Class 32 Exemption
CEQA Guidelines Section 15332, In-Fill Development Projects, states that a Class 32 exemption consists of projects characterized as in-fill development meeting the conditions described below.
(a) The project is consistent with the applicable general plan designation and all applicable general plan policies as well as with applicable zoning designation and regulations.
(b) The proposed development occurs within city limits on a project site of no more than five acres substantially surrounded by urban uses.
(c) The project site has no value as habitat for endangered, rare or threatened species.
Attachment I.A
Agenda Page 83
CEQA Class 32 Exemption – YMCA Downey
September 17, 2024
(d) Approval of the project would not result in any significant effects relating to traffic, noise, air quality, or water quality.
(e) The site can be adequately served by all required utilities and public services.
The Project site is currently zoned C-P and O-S and has a General Plan land use designation of O. The Project is permitted, or conditionally permitted, within these designations. The Project would be implemented consistent with all applicable General Plan and zoning policies and regulations. As part of Project approval, the Project includes a request to amend the zoning designation for the property located at 11531 Downey Avenue (APN 6255-013-032) from the O-S zone to the C-P zone. This zone change request is needed in order to correct inconsistencies between the City’s Zoning Map and General Plan Land Use Designation map. The corresponding appropriate land use zoning designation for the General Plan land use designation of Office (O) is the C-P zone.
This zone change request is a corrective matter is in accordance with State law and does not bestow any special privilege upon the property that would not otherwise be permissible in the current zoning designation.
Additionally, the Project site encompasses approximately 2.16 acres, located within the City of Downey limits.
Surrounding land uses include residential and office uses. Therefore, the proposed development occurs within City limits on a site of no more than five acres substantially surrounded by urban uses.
The Project site is currently developed with urban uses surrounded by typical ornamental landscaping. According to the Department of Fish and Wildlife Service’s National Wetland Mapper, the Project site does not contain any wetland, riparian habitat or other sensitive natural community.1 The Project site is currently developed and located in an urbanized area of the City. The Project site is located within an area that has not been identified as containing species identified as a candidate, sensitive, or special status species in local or regional plans, policies or regulations or by the California Department of Fish and Wildlife or the U.S. Fish and Wildlife Service. Therefore, the Project site has no value as habitat for endangered, rare or threatened species.
The construction and operation of a project of this scale would not typically result in significant environmental impacts. For Class 32 Exemptions, the City requires the following reports: Air Quality /Greenhouse Gas (GHG) Assessment; Noise Study; Trip Generation Assessment; and Vehicle Miles Traveled (VMT) Screening Evaluation.
These reports have been prepared to support the finding of a Class 32 exemption for the Project and are summarized below.
Trip Generation Assessment
The Project-specific Trip Generation Assessment is presented as Attachment A to this Memorandum. Pursuant to City of Downey requirements, the Trip Generation Assessment was conducted consistent with the County of Los Angeles Transportation Impact Analysis Guidelines (July 23, 2020) (County Guidelines).
YMCA was in operation at the Project site for 54 years, starting in 1966. The site became fully operational in 1977 and was fully operational for 43 years until March 2020 when it was shut down due to COVID-19. The existing structures on the Project site are currently vacant and could be re-occupied with uses consistent with the underlying zoning. The Project-specific Trip Generation Assessment used empirical data collected at two other
1 https://fwsprimary.wim.usgs.gov/wetlands/apps/wetlands-mapper/ Attachment I.A
Agenda Page 84
CEQA Class 32 Exemption – YMCA Downey
September 17, 2024
existing YMCA facilities with similar operations to calculate the historic operational levels of the previously occupied YMCA structures and establish the existing environmental conditions baseline. The Trip Generation Assessment concluded that the Project would result in a net reduction of 608 two -way daily vehicle trips when compared to the prior use of the Project site. The County Guidelines indicate that any development project which can demonstrate a net increase in the daily trip generation of less than 110 two -way trips per day would not require the preparation of a Transportation Impact Analysis. Based on the results of the Trip Generation Analysis, the Project would generate fewer than 110 net new daily trips. As such, additional traffic analysis is not required for this Project.
VMT Screening Evaluation
The Project VMT Screening Evaluation is presented as Attachment B to this Memorandum.
The County Guidelines provide details on screening criteria that are used to identify when a project is anticipated to result in a less than significant transportation impact. The screening criteria identified within the County Guidelines are:
• Non-Retail Project Trip Generation Screening (generates less than 110 net new daily trips) • Retail Project Site Plan Screening
• Proximity to Transit Based Screening
• Residential Land Use Based Screening
A project needs only meet one of the above screening criteria to be excused from further VMT analysis. As stated above, the Project would not generate more than 110 net new daily trips, and as such, meets the Non-Retail Project Trip Generation Screening criteria. Pursuant to County Guidelines, no further VMT analysis is required.
Air Quality and Greenhouse Gas Emissions
Project-related operational air quality impacts and operational greenhouse gas emissions derive primarily from vehicle trips generated by the Project. According to the Air Quality & Greenhouse Gas Assessment (Attachment C of this Memorandum), the proposed Project would not result in an exceedance of the SCAQMD regional significance threshold for construction-source or operational-source emissions.
As shown in Table 6 of the Assessment, the Project is anticipated to generate less emissions per day for pollutants of VOC, NOX, CO, SOX, PM10, and PM2.5 as compared to emissions generated by the existing uses. Project emissions would not exceed applicable thresholds.
Additionally, Table 12 of the Assessment shows that the Project is anticipated to generate less GHG emissions per day as compared to emissions generated by the existing uses. The Project would result in a net decrease of approximately 463.70 MTCO2e/yr; the proposed Project would not exceed the SCAQMD’s numeric threshold of 3,000 MTCO2e/yr.
Noise Assessment
The Project Noise Assessment is presented as Attachment D to this Memorandum.
According to City Municipal Code Section 4606.5, construction noise shall not occur between 9:00 p.m. and 7:00 a.m., nor should construction noise exceed 85 dBA Lmax across any property boundary at any time. As presented Attachment I.A
Agenda Page 85
CEQA Class 32 Exemption – YMCA Downey
September 17, 2024
in Table 3 of the Noise Assessment, peak noise levels associated with Project construction are expected to reach up to 78.8 dBA Lmax. As such, construction noise would not exceed City thresholds.
Project-related operational noise sources are expected to include a pickleball court, roof-top air conditioning units, and parking lot vehicle movements. It is noted that the Project includes a 10-foot high Acoustifence along the pickleball court, as shown in Exhibit 4 of the Noise Assessment. Additionally, the pickleball court would be closed during the nighttime hours. The City of Downey Municipal Code, Chapter 6 Section 4606.3, identifies exterior noise levels standards of 55 dBA Leq for the daytime hours (7:00 a.m. to 10:00 p.m.) and 45 dBA Leq during the nighttime (10:00 p.m. to 7:00 a.m.) hours. As shown in Table 2 of the Noise Assessment, peak operational noise levels for the Project would reach up to 47.8 dBA Leq during the daytime hours and 43.0 dBA Leq during the nighttime hours at nearby sensitive receptors. As such, operational noise would not exceed City thresholds.
Utilities and Public Services
The Project site is currently served by existing utilities and public services. The Project represents an approximate 34,348 sf reduction in on-site uses (61,756 sf of existing uses minus 27,408 sf of proposed new uses), with corollary reductions in utilities and public services demands. The Project would implement all necessary on-site utility and storm water management infrastructure, consistent with City requirements. Therefore, the site can be adequately served by all required utilities and public services.
B. Review Of Exceptions to The Categorical Exemption
CEQA Guidelines include exceptions to all exemptions. As codified in Guidelines Section 15300.2, a project that would otherwise fit into an exemption must not be disqualified by the following sections:
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 adopted pursuant to law by federal, state, or local agencies. 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. c) Significant Effect. A categorical exemption 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. 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. 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. 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 applicability of the above-listed conditions to the YMCA Project is discussed below.
Attachment I.A
Agenda Page 86
CEQA Class 32 Exemption – YMCA Downey
September 17, 2024
a) This Condition would not apply under a Class 32 exemption, as it only applies to Classes 3, 4, 5, 6, and 11.
b) As presented within this Memorandum, the Project would not result in any significant individual or cumulative environmental impacts. As such, Condition b) is not applicable to the Project.
c) No significant effects would occur as a result of the Project. The Project represents the redevelopment of typical urban uses within a developed area of the City. No unusual circumstances exist. As such, Condition c) is not applicable to the Project.
d) According to the California Department of Transportation (Caltrans) California Scenic Highway Mapping System, the nearest officially designated state scenic highway is a portion of California State Route 91 located approximately 18.5 miles to the southeast. This section of scenic highway is not visible from the Project site or surrounding areas.2 As such, the Project would not result in damage to scenic resources within a highway officially designated as a state scenic highway; Condition d) is not applicable.
e) Pursuant to Government Code Section 65962.5, the Hazardous Waste and Substances Sites (Cortese) List is a planning document used by the State and local agencies to comply with the California Environmental Quality Act requirements in providing information about the location of hazardous materials release sites.
Below are the data resources that provide information regarding the facilities or sites identified as meeting the Cortese List requirements.
• List of Hazardous Waste and Substances sites from Department of Toxic Substances Control (DTSC) EnviroStor database.
• List of Leaking Underground Storage Tank Sites from the State Water Board’s GeoTracker database.
• List of solid waste disposal sites identified by Water Board with waste constituents above hazardous waste levels outside the waste management unit.
• List of “active” Cease and Desist Orders and Cleanup and Abatement Orders from Water Board.
• List of hazardous waste facilities subject to corrective action pursuant to Section 25187.5 of the Health and Safety Code, identified by DTSC.
Based on a review of the Cortese List maintained by the CalEPA, the Project site is not identified as a hazardous materials site pursuant to Government Code Section 65962.5. 3 Additionally, the Project’s Phase 1 ESA (Attachment E of this Memorandum) revealed no evidence of any recognized environmental conditions (RECs) in connection with the Project site. Condition e) would not apply.
f) Condition f) requires consideration of whether the Project may cause a substantial adverse change in the significance of a historical resource. The definition of "historical resources" is contained in CEQA

Guidelines Section 15064.5. Buildings that are 50 years or older are required to be evaluated to determine whether they meet the criteria to be considered significant historical resources.
The structures on the Project site meet the 50-year age threshold for evaluation. To this end, a Cultural Resources Study (Attachment F of this Memorandum) was prepared for the Project to locate and record any cultural resources within the site. The Study concluded that none of the structures on the Project site are associated with significant individuals, significant architectural examples, or are able to provide more information regarding the history of Downey or the State of California. As such, the on-site buildings are not considered historically significant under CEQA. The Project would not cause a substantial adverse change in the significance of a historical resource.
C. Conclusion
Based on the technical analyses prepared for the Project, the Project would not result in any significant environmental impacts. Additionally, the Project meets the conditions of a Class 32 exemption and would not conflict with any of the exceptions as codified in CEQA Guidelines Section 15300.

YMCA DOWNEY NOISE ASSESSMENT
Nicole Morse,
Urban Crossroads, Inc. is pleased to provide the following Noise Assessment for the YMCA Downey (Project), which is at 11531 Downey Avenue which is northwest of Downey Avenue, south of Firestone Boulevard, and east of Paramount Boulevard in the City of Downey (Assessor’s Parcel Numbers [APNs] 6255-013-032, -033, and -034).
PROJECT OVERVIEW
The site is currently developed with 3 structures totaling 61,756 square feet (3,254- square-foot building at 11525 Downey Avenue, 57,673-square-foot building at 11531 Downey Avenue, and 829-square-foot building at 8268 Arnett Street). The site was previously occupied by a YMCA which is currently not operational. The Project includes demolition of the existing structures on -site and developing an 18,808-square-foot gymnasium, 975-square-foot lobby/restrooms, and retrofitting of an approximate 7,625-square-foot existing gymnasium (total of 27,408 square feet). A preliminary site plan for the proposed Project is shown in Exhibit 1. The proposed Project is anticipated to have an opening year of 2026.
SUMMARY OF FINDINGS
The Noise Assessment shows that the Project will not exceed the established City of Downey operational or construction noise thresholds with nighttime restrictions and the installation of a 10-foot high Acoustifence for the planned pickleball court. Therefore, the Project operational and construction noise impacts are considered less than significant at the nearby noise-sensitive receiver locations.

NOISE FUNDAMENTALS
Noise is simply defined as "unwanted sound." Sound becomes unwanted when it interferes with normal activities, when it causes actual physical harm or when it has adverse effects on health.
Noise is measured on a logarithmic scale of sound pressure level known as a decibel (dB). A- weighted decibels (dBA) approximate the subjective response of the human ear to broad frequency noise source by discriminating against very low and very high frequencies of the audible spectrum. They are adjusted to reflect only those frequencies which are audible to the human ear. Exhibit 2 presents a summary of the typical noise levels and their subjective loudness and effects that are described in more detail below.
Since the range of intensities that the human ear can detect is so large, the scale frequently used to measure intensity is a scale based on multiples of 10, the logarithmic scale. The scale for measuring intensity is the decibel scale. Each interval of 10 decibels indicates a sound energy ten times greater than before, which is perceived by the human ear as being roughly twice as loud. (1) The most common sounds vary between 40 dBA (very quiet) to 100 dBA (very loud). Normal conversation at three feet is roughly at 60 dBA, while loud jet flyover noises equate to 110 dBA at approximately 1,000 feet, which can cause serious discomfort. (2) Another important aspect of noise is the duration of the sound and the way it is described and distributed in time.

RECEIVER LOCATIONS
To assess the potential for noise impacts, the following receiver locations, as shown on Exhibit 3, were identified as representative locations for analysis. Sensitive uses or receivers are generally defined as locations where people reside or where the presence of unwanted sound could otherwise adversely affect the use of the land. To describe the p otential off-site Project noise levels, four receiver locations in the vicinity of the Project site were identified, including the location of the nearest existing noise sensitive residential receiver (R2) located approximately 7 feet north of the Project site boundary.
The selection of receiver locations is based on FHWA guidelines and is consistent with additional guidance provided by Caltrans and the FTA. Other sensitive land uses in the Project study area that are located at greater distances than those identified in this noise study will experience lower noise levels than those presented in this report due to the additional attenuation from distance and the shielding of intervening structures.
NOISE PREDICTION MODEL
To fully describe the exterior operational noise levels from the Project, Urban Crossroads, Inc. developed a noise prediction model using the CadnaA (Computer Aided Noise Abatement) computer program. CadnaA can analyze multiple types of noise sources using the spatially accurate Project site plan, georeferenced Nearmap aerial imagery, topography, buildings, and barriers in its calculations to predict outdoor noise levels. Using the ISO 9613-2 protocol, CadnaA will calculate the distance from each noise source to the noise receiver locations, using the ground absorption, distance, and barrier/building attenuation inputs to provide a summary of noise level at each receiver and the partial noise level contributions by noise source. The noise level calculations provided in this noise assessment account for the distance attenuation provided due to geometric spreading, when sound from a localized stationary source (i.e., a point source) propagates uniformly outward in a spherical pattern. A default ground attenuation factor of 0.5 was used in the CadnaA noise analysis to account for mixed ground representing a combination of hard and soft surfaces.
OPERATIONAL NOISE ANALYSIS
This section analyzes the potential stationary-source operational noise impacts at the nearby receiver locations resulting from the operation of the proposed YMCA Downey Project. This operational noise analysis is intended to describe noise level impacts associated with the typical of daytime and nighttime activities at the Project site. The on-site Project-related noise sources are expected to include Pickleball, roof-top air conditioning units, and parking lot vehicle movements. No pickleball activities shall be permitted during the noise sensitive nighttime hours of 10:00 p.m. to 7:00 a.m.

OPERATIONAL NOISE STANDARDS
To analyze noise impacts originating from the YMCA Downey, operational source noise is evaluated against standards established under a City’s Municipal Code. For noise-sensitive residential property, the City of Downey Municipal Code, Chapter 6 Section 4606.3, identifies exterior noise levels standards of 55 dBA Leq for the daytime hours (7:00 a.m. to 10:00 p.m.) and 45 dBA Leq during the nighttime (10:00 p.m. to 7:00 a.m.) hours. The City of Downey Municipal Code Noise Standards are included in Appendix A.
OPERATIONAL NOISE SOURCES
To estimate the Project operational noise impacts, reference noise level measurements were collected from similar types of activities to represent the noise levels expected with the development of the proposed Project. While sound pressure levels (e.g., L eq) quantify in decibels the intensity of given sound sources at a reference distance, sound power levels (L w) are connected to the sound source and are independent of distance. Sound pressure levels vary substantially with distance from the source and diminish because of intervening obstacles and barriers, air absorption, wind, and other factors. Sound power is the acoustical energy emitted by the sound source and is an absolute value that is not affected by the environment. The reference project operational noise levels are based on the Project related noise source activities shown on Exhibit D. The reference project operational reference noise levels and sound power levels are summarized below on Table 1.

"Daytime" = 7:00 a.m. - 10:00 p.m.; "Nighttime" = 10:00 p.m. - 7:00 a.m. 2 Sound power level represents the total amount of acoustical energy (noise level) produced by a sound source independent of distance or surroundings. Sound power levels calculated using the CadnaA noise model at the reference distance to the noise source. Numbers may vary due to size differences between point and area noise sources.
OPERATIONAL NOISE LEVEL COMPLIANCE
Using the reference noise levels to represent the proposed Project operations that include Pickleball, roof-top air conditioning units, and parking lot vehicle movements, Urban Crossroads, Inc. calculated the operational source noise levels that are expected to be generated at the Project site. Table 2 shows the unmitigated Project operational noise levels during the daytime hours of 7:00 a.m. to 10:00 p.m. The daytime hourly noise levels at the off-site receiver locations are expected to range from 41.3 to 47.8 dBA Leq. The nighttime hourly noise levels at the off-site receiver locations are expected to range from 38.3 to 43.0 dBA Leq. The differences between the Attachment I.B

Table 2 shows that the unmitigated operational noise levels associated with YMCA Downey Project will not exceed the City of Downey exterior noise level standards.
CONSTRUCTION NOISE ANALYSIS
This section analyzes potential impacts resulting from the short-term construction activities associated with the development of the Project. According to the City’s Municipal Code Section 4606.5, noise sources associated with construction, repair or remodeling equipment and devices and other related construction noise sources shall be exempted from the provisions of this chapter provided a valid permit for such construction, repair, or remodeling shall have been obtained from the City. In any circumstance other than emergency work, no repair or remodeling shall take place between the hours of 9:00 p.m. of one day and 7:00 a.m. of the following day, and no repair or remodeling shall exceed 85 dBA Lmax across any property boundary at any time during the course of a 24-hour day.
To describe construction noise activities, this construction noise analysis was prepared using reference construction equipment noise levels from the Federal Highway Administration (FHWA) published the Roadway Construction Noise (4 p. 179) Model (RCNM), which includes a national database of construction equipment reference noise emission levels. (3) Using a composite construction equipment reference noise level of 90.0 dBA Lmax at 50 feet to describe Project grading activities, calculations of the Project construction noise level impacts at the nearby sensitive receiver locations were completed using the CadnaA noise prediction model. As shown on Table 3, the highest construction noise levels are expected to range from 74.2 to 78.8 dBA Lmax at the nearby receiver locations. Appendix C includes the detailed CadnaA construction noise model inputs. The construction noise analysis shows that the nearest receiver locations will not exceed the 85 dBA Lmax significance threshold during Project construction activities as shown on Table 3. Therefore, the noise impacts due to Project construction noise are considered less than significant at all receiver locations.

§ 4606.1. DECLARATION OF POLICY.
The Council finds and declares that noise is a major source of environmental pollution which represents a threat to the serenity and quality of life in the City. Excess noise often has an adverse physiological and psychological effect on human beings, thus contributing an economic and social loss to the community. Accordingly, it is the policy of the Council to establish standards for noise level limits for the various time periods and areas within the City. Noise in excess of the limits provided in this chapter shall constitute a public nuisance.
(Added by Ord. 508, adopted 6-22-76 )
§ 4606.2. DEFINITIONS.
As used in this chapter, unless the context otherwise clearly indicates, the following words and phrases are defined to mean and include:
"A-Weighted Sound Level." The total sound level in decibels of all sound as measured with a sound level meter with a reference pressure of 20 microPascals per square meter using the A-weighted network (scale at slow response). The unit of measurement shall be defined as db(A).
"Ambient Noise." The all-encompassing noise associated with a given environment, providing for the issuance of such permit upon the satisfactory showing that such outdoor paging system is being used and operated in violation of the provisions of any law or is being used in such a manner as to constitute a nuisance, public or private. Such revocation shall be by delivering a notice of revocation, with the reasons therefor, to the person applying for the permit in person or by mailing such notice to the address of the applicant as set forth in his application. Such revocation shall be effective within five days following the date of delivery or the date of mailing, unless within such period of time the applicant files with the City Manager a demand for a hearing.
If such a demand for a hearing is filed, the City Manager shall set the matter for a hearing before him and, at the conclusion of such hearing, shall make his determination as to whether there was good cause for the revocation, and the decision of the City Manager shall be final.

In the event the alleged violator cannot be located in order to serve the notice of intention to prosecute, the notice as required herein shall be deemed to be given upon mailing such notice by registered or certified mail to the alleged violator at his last known address or at the place where the violation occurred, in which event the 15 day period shall commence at the date of the day following the mailing of such notice. In the event of any conflict between the provisions of this chapter, the most restrictive shall be applicable. (Added by Ord. 508, eff. 6-22-76 )

YMCA DOWNEY AIR QUALITY & GREENHOUSE GAS ASSESSMENT
Tracy Zinn,
Urban Crossroads, Inc. is pleased to provide the following Air Quality & Greenhouse Gas Assessment for the YMCA Downey (Project), which is at 11531 Downey Avenue which is northwest of Downey Avenue, south of Firestone Boulevard, and east of Paramount Boulevard in the City of Downey (Assessor’s Parcel Numbers [APNs] 6255-013-032, -033, and -034).
PROJECT OVERVIEW
The site is currently developed with 3 structures totaling 61,756 square feet (3,254- square-foot building at 11525 Downey Avenue, 57,673-square-foot building at 11531 Downey Avenue, and 829-square-foot building at 8268 Arnett Street). The site was previously occupied by a YMCA which is currently not operational. The Project includes demolition of the existing structures on-site and developing an 18,808-square-foot gymnasium, 975-square-foot lobby/restrooms, and retrofitting of an approximate 7,625-square-foot existing gymnasium (total of 27,408 square feet). A preliminary site plan for the proposed Project is shown in Exhibit 1. The proposed Project is anticipated to have an opening year of 2026.
SUMMARY OF FINDINGS
Results of the assessment indicate that the Project would result in a less than significant with respect to air quality and greenhouse gases and no mitigation is required.

PROJECT AIR QUALITY IMPACTS
AIR QUALITY SETTING
SOUTH COAST AIR BASIN (SCAB)
The Project site is located in the SCAB within the jurisdiction of South Coast Air Quality Management District (SCAQMD) (1). The SCAQMD was created by the 1977 Lewis-Presley Air Quality Management Act, which merged four county air pollution control bodies into one regional district. Under the Act, the SCAQMD is responsible for bringing air quality in areas under its jurisdiction into conformity with federal and state air quality standards. As previously stated, the Project site is located within the SCAB, a 6,745-square mile subregion of the SCAQMD, which includes portions of Los Angeles, Riverside, and San Bernardino Counties, and all of Orange County.
The SCAB is bounded by the Pacific Ocean to the west and the San Gabriel, San Bernardino, and San Jacinto Mountains to the north and east. The Los Angeles County portion of the Mojave Desert Air Basin is bounded by the San Gabriel Mountains to the south and west, the Los Angeles / Kern County border to the north, and the Los Angeles / San Bernardino County border to the east. The Riverside County portion of the Salton Sea Air Basin is bounded by the San Jacinto Mountains in the west and spans eastward up to the Palo Verde Valley.
Regional Climate
The regional climate has a substantial influence on air quality in the SCAB. In addition, the temperature, wind, humidity, precipitation, and amount of sunshine influence the air quality.
The annual average temperatures throughout the SCAB vary from the low to middle 60s degrees Fahrenheit (°F). Due to a decreased marine influence, the eastern portion of the SCAB shows greater variability in average annual minimum and maximum temperatures. January is the coldest month throughout the SCAB, with average minimum temperatures of 47°F in downtown Los Angeles and 36°F in San Bernardino. All portions of the SCAB have recorded maximum temperatures above 100°F.
Although the climate of the SCAB can be characterized as semi-arid, the air near the land surface is quite moist on most days because of the presence of a marine layer. This shallow layer of sea air is an important modifier of SCAB climate. Humidity restricts visibility in the SCAB, and the conversion of sulfur dioxide (SO2) to sulfates (SO4) is heightened in air with high relative humidity.
The marine layer provides an environment for that conversion process, especially during the spring and summer months. The annual average relative humidity within the SCAB is 71 percent (%) along the coast and 59% inland. Since the ocean effect is dominant, periods of heavy early morning fog are frequent and low stratus clouds are a characteristic feature. These effects decrease with distance from the coast.
More than 90% of the SCAB’s rainfall occurs from November through April. The annual average rainfall varies from approximately nine inches in Riverside to fourteen inches in downtown Los Angeles. Monthly and yearly rainfall totals are extremely variable. Summer rainfall usually consists of widely scattered thunderstorms near the coast and slightly heavier shower activity in the eastern portion of the SCAB with frequency being higher near the coast.

Due to its generally clear weather, about three-quarters of available sunshine is received in the SCAB. The remaining one-quarter is absorbed by clouds. The ultraviolet portion of this abundant radiation is a key factor in photochemical reactions. On the shortest day of the year there are approximately 10 hours of possible sunshine, and on the longest day of the year there are approximately 14½ hours of possible sunshine.
The importance of wind to air pollution is considerable. The direction and speed of the wind determines the horizontal dispersion and transport of the air pollutants. During the late autumn to early spring rainy season, the SCAB is subjected to wind flows associated with the traveling storms moving through the region from the northwest. This period also brings five to ten periods of strong, dry offshore winds, locally termed “Santa Anas” each year. During the dry season, which coincides with the months of maximum photochemical smog concentrations, the wind flow is bimodal, typified by a daytime onshore sea breeze and a nighttime offshore drainage wind.
Summer wind flows are created by the pressure differences between the relatively cold ocean and the unevenly heated and cooled land surfaces that modify the general northwesterly wind circulation over southern California. Nighttime drainage begins with the radiational cooling of the mountain slopes. Heavy, cool air descends the slopes and flows through the mountain passes and canyons as it follows the lowering terrain toward the ocean. Another characteristic wind regime in the SCAB is the “Catalina Eddy,” a low level cyclonic (counterclockwise) flow centered over Santa Catalina Island which results in an offshore flow to the southwest. On most spring and summer days, some indication of an eddy is apparent in coastal sections.
In the SCAB, there are two distinct temperature inversion structures that control vertical mixing of air pollution. During the summer, warm high-pressure descending (subsiding) air is undercut by a shallow layer of cool marine air. The boundary between these two layers of air is a persistent marine subsidence/inversion. This boundary prevents vertical mixing which effectively acts as an impervious lid to pollutants over the entire SCAB. The mixing height for the inversion structure is normally situated 1,000 to 1,500 feet above mean sea level.
A second inversion-type forms in conjunction with the drainage of cool air off the surrounding mountains at night followed by the seaward drift of this pool of cool air. The top of this layer forms a sharp boundary with the warmer air aloft and creates nocturnal radiation inversions.
These inversions occur primarily in the winter when nights are longer and onshore flow is weakest. They are typically only a few hundred feet above mean sea level. These inversions effectively trap pollutants, such as nitrogen oxides (NOX) and carbon monoxide (CO) from vehicles, as the pool of cool air drifts seaward. Winter is therefore a period of high levels of primary pollutants along the coastline.
Wind Patterns and Project Location
The distinctive climate of the Project area and the SCAB is determined by its terrain and geographical location. The SCAB is located in a coastal plain with connecting broad valleys and low hills, bounded by the Pacific Ocean in the southwest quadrant with high mountains forming the remainder of the perimeter.
Wind patterns across the south coastal region are characterized by westerly and southwesterly onshore winds during the day and easterly or northeasterly breezes at night. Winds are characteristically light although the speed is somewhat greater during the dry summer months than during the rainy winter season.

Criteria Pollutants
Both the U.S. Environmental Protection Agency (EPA) and the California Air Resources Board (CARB) have established ambient air quality standards for common pollutants. These ambient air quality standards are levels of contaminants representing safe levels that avoid specific adverse health effects associated with each pollutant. The ambient air quality standards cover what are called “criteria” pollutants because the health and other effects of each pollutant are described in criteria documents. The six criteria pollutants are ozone (O3) (precursor emissions include NOX and reactive organic gases (ROG), CO, particulate matter (PM), nitrogen dioxide (NO2), sulfur dioxide (SO2), and lead. Areas that meet ambient air quality standards are classified as attainment areas, while areas that do not meet these standards are classified as nonattainment areas. The Riverside County portion of the SCAB is designated as a nonattainment area for the federal O3 and PM2.5 standards and is also a nonattainment area for the state standards for O3, PM10, and PM2.5.
Toxic Air Contaminants (TAC) Trend
In 1984, as a result of public concern for exposure to airborne carcinogens, CARB adopted regulations to reduce the amount of TAC emissions resulting from mobile and area sources, such as cars, trucks, stationary products, and consumer products. According to the Ambient and Emission Trends of Toxic Air Contaminants in California journal article (2) which was prepared for CARB, results show that between 1990-2012, ambient concentration and emission trends for the seven TACs responsible for most of the known cancer risk associated with airborne exposure in California have declined significantly (between 1990 and 2012). The seven TACs studied include those that are derived from mobile sources: diesel particulate matter (DPM), benzene (C6H6), and 1,3-butadiene (C4H6); those that are derived from stationary sources: perchloroethylene (C2Cl4) and hexavalent chromium (Cr(VI)); and those derived from photochemical reactions of emitted VOCs: formaldehyde (CH2O) and acetaldehyde (C2H4O)1. The decline in ambient concentration and emission trends of these TACs are a result of various regulations CARB has implemented to address cancer risk.
Some people are especially sensitive to air pollution and are given special consideration when evaluating air quality impacts from projects. These groups of people include children, the elderly, and individuals with pre-existing respiratory or cardiovascular illness. Structures that house these persons or places where they gather are defined as “sensitive receptors”. These structures typically include uses such as residences, hotels, and hospitals where an individual can remain for 24 hours. Consistent with the LST Methodology, the nearest land use where an individual could remain for 24 hours to the Project site has been used to determine construction and operational air quality impacts for emissions of PM10 and PM2.5, since PM10 and PM2.5 thresholds are based on a 24-hour averaging time.
Receptors in the Project study area are described below. All distances are measured from the Project site boundary to the outdoor living areas (e.g., backyards) or at the building façade,
1 It should be noted that ambient DPM concentrations are not measured directly. Rather, a surrogate method using the coefficient of haze (COH) and elemental carbon (EC) is used to estimate DPM concentrations.

REGULATORY BACKGROUND
FEDERAL REGULATIONS
The EPA is responsible for setting and enforcing the national ambient air quality standards (NAAQS) for O3, CO, NOX, SO2, PM10, and lead (Pb) (3). The EPA has jurisdiction over emissions sources that are under the authority of the federal government including aircraft, locomotives, and emissions sources outside state waters (Outer Continental Shelf). The EPA also establishes emission standards for vehicles sold in states other than California. Automobiles sold in California must meet the stricter emission requirements of CARB.
The Federal Clean Air Act (CAA) was first enacted in 1955 and has been amended numerous times in subsequent years (1963, 1965, 1967, 1970, 1977, and 1990). The CAA establishes the federal air quality standards, the NAAQS, and specifies future dates for achieving compliance (4). The CAA also mandates that each state submit and implement state implementation plans (SIPs) for local areas not meeting these standards. These plans must include pollution control measures that demonstrate how the standards will be met.
The 1990 amendments to the CAA that identify specific emission reduction goals for areas not meeting the NAAQS require a demonstration of reasonable further progress toward attainment and incorporate additional sanctions for failure to attain or to meet interim milestones. The sections of the CAA most directly applicable to the development of the Project site include Title I (Non-Attainment Provisions) and Title II (Mobile Source Provisions) (5) (6). Title I provisions were established with the goal of attaining the NAAQS for the following criteria pollutants O3, NO2, SO2, PM10, CO, PM2.5, and Pb. The NAAQS were amended in July 1997 to include an additional standard for O3 and to adopt a NAAQS for PM2.5.
Mobile source emissions are regulated in accordance with Title II provisions. These provisions require the use of cleaner burning gasoline and other cleaner burning fuels such as methanol and natural gas. Automobile manufacturers are also required to reduce tailpipe emissions of hydrocarbons and NOX. NOX is a collective term that includes all forms of NOX which are emitted as byproducts of the combustion process.

CALIFORNIA REGULATIONS
CARB
The CARB, which became part of the California EPA (CalEPA) in 1991, is responsible for ensuring implementation of the California Clean Air Act (AB 2595), responding to the federal CAA, and for regulating emissions from consumer products and motor vehicles. AB 2595 mandates achievement of the maximum degree of emissions reductions possible from vehicular and other mobile sources in order to attain the state ambient air quality standards by the earliest practical date. The CARB established the California ambient air quality standards (CAAQS) for all pollutants for which the federal government has NAAQS and, in addition, establishes standards for SO4, visibility, hydrogen sulfide (H2S), and vinyl chloride (C2H3Cl). However, at this time, H2S and C2H3Cl are not measured at any monitoring stations in the SCAB because they are not considered to be a regional air quality problem. Generally, the CAAQS are more stringent than the NAAQS (7) (8).
Local air quality management districts, such as the SCAQMD, regulate air emissions from stationary sources such as commercial and industrial facilities. All air pollution control districts have been formally designated as attainment or non-attainment for each CAAQS.
Serious non-attainment areas are required to prepare Air Quality Management Plans (AQMP) that include specified emission reduction strategies in an effort to meet clean air goals. These plans are required to include:
• Application of Best Available Retrofit Control Technology to existing sources; • Developing control programs for area sources (e.g., architectural coatings and solvents) and indirect sources (e.g. motor vehicle use generated by residential and commercial development);
• A District permitting system designed to allow no net increase in emissions from any new or modified permitted sources of emissions;
• Implementing reasonably available transportation control measures and assuring a substantial reduction in growth rate of vehicle trips and miles traveled; • Significant use of low emissions vehicles by fleet operators; • Sufficient control strategies to achieve a 5% or more annual reduction in emissions or 15% or more in a period of three years for ROGs, NOX, CO and PM10. However, air basins may use alternative emission reduction strategy that achieves a reduction of less than 5% per year under certain circumstances.
AQMP
Currently, the NAAQS and CAAQS are exceeded in most parts of the SCAB. In response, the SCAQMD has adopted a series of AQMP to meet the state and federal ambient air quality standards (9). AQMPs are updated regularly in order to more effectively reduce emissions, accommodate growth, and to minimize any negative fiscal impacts of air pollution control on the economy.

APPLICABLE REGULATORY REQUIRMENTS
SCAQMD Rules that are currently applicable during construction activity for this Project include but are not limited to Rule 403 (Fugitive Dust) and Rule 1113 (Architectural Coatings) (10) (11).
SCAQMD Rule 403
This rule is intended to reduce the amount of particulate matter entrained in the ambient air as a result of anthropogenic (human-made) fugitive dust sources by requiring actions to prevent and reduce fugitive dust emissions. Rule 403 applies to any activity or human-made condition capable of generating fugitive dust and requires best available control measures to be applied to earth moving and grading activities. This rule is intended to reduce PM10 emissions from any transportation, handling, construction, or storage activity that has the potential to generate fugitive dust. PM10 suppression techniques are summarized below. • Portions of a construction site to remain inactive longer than a period of three months will be seeded and watered until grass cover is grown or otherwise stabilized. • All onsite roads will be paved as soon as feasible or watered periodically or chemically stabilized.
• All material transported offsite will be either sufficiently watered or securely covered to prevent excessive amounts of dust.
• The area disturbed by clearing, grading, earthmoving, or excavation operations will be minimized at all times.
• Where vehicles leave a construction site and enter adjacent public streets, the streets will be swept daily or washed down at the end of the workday to remove soil tracked onto the paved surface.
SCAQMD Rule 1113
This rule serves to limit the volatile organic compound (VOC) content of architectural coatings used on projects in the SCAQMD. Any person who supplies, sells, offers for sale, or manufactures any architectural coating for use on projects in the SCAQMD must comply with the current VOC standards set in this rule.
METHODOLOGY
In August 2023, the California Air Pollution Control Officers Association (CAPCOA) in conjunction with other California air districts, including SCAQMD, released the latest version of the CalEEMod Version 2022.1.1.22. The purpose of this model is to calculate construction-source and operational-source criteria pollutant (VOCs, NOX, SOX, CO, PM10, and PM2.5) and GHG emissions from direct and indirect sources; and quantify applicable air quality and GHG reductions achieved from mitigation measures (12). Accordingly, the latest version of CalEEMod has been used for this Project to determine construction and operational air quality and greenhouse gas emissions.
AIR QUALITY REGIONAL EMISSIONS THRESHOLDS
The SCAQMD has developed regional significance thresholds for criteria pollutants, as summarized at Table 1 (13). The SCAQMD’s CEQA Air Quality Significance Thresholds (March Attachment I.C
Agenda Page 130
Tracy Zinn, T&B Planning, Inc.
May 14, 2024
15985-03 AQ & GHG Assessment
2023) indicate that any projects in the South Coast Air Basin (SCAB) with daily emissions that exceed any of the indicated thresholds should be considered as having an individually and cumulatively significant air quality impact.

AIR QUALITY LOCALIZED EMISSIONS THRESHOLDS
For this Project, the appropriate SRA for the LST analysis is the SCAQMD Southeast Los Angeles County Area monitoring station (SRA 5). LSTs apply to CO, NO2, PM10, and PM2.5. The SCAQMD produced look-up tables for projects less than or equal to 5 acres in size. The SCAQMD’s screening look-up tables are utilized in determining localized impacts. It should be noted that since the look- up tables identify thresholds at only 1 acre, 2 acres, and 5 acres, linear regression has been utilized to determine localized significance thresholds. Consistent with SCAQMD guidance, the thresholds presented in Table 2 were calculated by interpolating the threshold values for the Project’s disturbed acreage.
The acres disturbed is based on the equipment list and days in the demolition, site preparation, and grading phase according to the anticipated maximum number of acres a given piece of equipment can pass over in an 8-hour workday. The equipment-specific grading rates are summarized in the CalEEMod user’s guide, Appendix A: Calculation Details for CalEEMod (14). It should be noted that the disturbed area per day is representative of a piece of equipment making multiple passes over the same land area. In other words, one Rubber Tired Dozer can make multiple passes over the same land area totaling 0.5 acres in a given 8-hour day. Appendix A of the CalEEMod User Manual only identifies equipment-specific grading rates for Crawler Tractors, Graders, Rubber Tired Dozers, and Scrapers; therefore, Tractors/Loaders/Backhoes equipment that was included in the grading phase was replaced with Crawler Tractors. For analytical purposes, emissions associated with peak demolition, site preparation, and grading activities are considered for purposes of localized significance thresholds (LSTs) since this phase represents the maximum localized emissions that would occur. The Project’s construction activities could disturb a maximum of approximately 0.5 acre per day for demolition, 2 acres per day for site preparation, and 2 acres per day for grading activities. Any other construction phases of development would result in lesser emissions and consequently lesser impacts than what is disclosed herein. As such, Table 2 presents thresholds for localized construction and operational emissions. It should be noted that a 1 acre per day disturbance area for demolition activities was utilized as this is the SCAQMD look-up tables minimum acreage.

CONSTRUCTION ACTIVITIES
Construction activities associated with the Project would result in emissions of VOCs, NOX, SOX, CO, PM10, and PM2.5. Construction related emissions are expected from the following construction activities:
• Demolition
• Site Preparation
• Grading (Import/Export)
• Building Construction
• Paving
• Architectural Coating
DEMOLITION ACTIVITIES
The Project site is currently developed with 3 existing structures that will be demolished, resulting in approximately 54,131 square feet of demolished material.
GRADING ACTIVITIES
Dust is typically a major concern during grading activities. Because such emissions are not amenable to collection and discharge through a controlled source, they are called “fugitive emissions”. Fugitive dust emissions rates vary as a function of many parameters (soil silt, soil moisture, wind speed, area disturbed, number of vehicles, depth of disturbance or excavation, etc.). CalEEMod was utilized to calculate fugitive dust emissions resulting from this phase of activity. This analysis assumes that earthwork activities are expected to balance on site and no import or export of soils would be required. The CalEEMod default trip length of 20-miles will be used to analyze the emissions associated with export activities.
ON-ROAD TRIPS
Construction generates on-road vehicle emissions from vehicle usage for workers, vendors, and haul trucks commuting to and from the site. Worker and hauling trips are based on CalEEMod defaults. It should be noted that for vendor trips, specifically, CalEEMod only assigns vendor trips Attachment I.C
Agenda Page 132
Tracy Zinn, T&B Planning, Inc.
May 14, 2024
15985-03 AQ & GHG Assessment
to the Building Construction phase. Vendor trips would likely occur during all phases of construction. As such, the CalEEMod defaults for vendor trips have been adjusted based on a ratio of the total vendor trips to the number of days of each subphase of activity.
CONSTRUCTION DURATION
For purposes of analysis, construction of Project is expected to commence in November 2024 and would last through December 2025. The construction schedule utilized in the analysis represents a “conservative” analysis scenario should construction occur any time after the respective dates since emission factors for construction decrease as time passes and the analysis year increases due to emission regulations becoming more stringent2. The duration of construction activity and associated equipment represents a reasonable approximation of the expected construction fleet as required per CEQA Guidelines (15).
CONSTRUCTION EQUIPMENT
CalEEMod default parameters for equipment have been used. Consistent with industry standards and typical construction practices, each piece of equipment will operate up to a total of eight (8) hours per day, or more than two-thirds of the period during which construction activities are allowed pursuant to the code.
REGIONAL CONSTRUCTION EMISSIONS SUMMARY
The estimated maximum daily construction emissions are summarized on Table 3, and as shown, the Project construction-source emissions would not exceed SCAQMD regional thresholds. Thus, the Project would result in a less than significant impact associated with construction activities.
Detailed Construction model outputs are presented in Attachment A.
2 As shown in the CalEEMod User’s Guide Version 2022, Appendix G “Table G-11. Statewide Average Annual Offoad Equipment Emission Factors” as the analysis year increases, emission factors for the same equipment pieces decrease due to the natural turnover of older equipment being replaced by newer less polluting equipment and new regulatory requirements.

REGIONAL OPERATIONAL EMISSIONS
Operational activities associated with the Project would result in emissions of VOCs, NOX, CO, SOX, PM10, and PM2.5. Operational related emissions are expected from the following primary sources:
area source emissions, energy source emissions, and mobile source emissions.
The Project related operational air quality impacts derive primarily from vehicle trips generated by the Project. Trip characteristics available from the YMCA Downey Trip Generation Assessment were utilized in this analysis (16).
The estimated operation-source emissions from the Project are summarized on Table 4. Detailed operation model outputs are presented in Attachment A. As shown on Table 4, operational- source emissions would not exceed the applicable SCAQMD regional thresholds for emissions of any criteria pollutant.

LOCALIZED CONSTRUCTION EMISSIONS
The analysis makes use of methodology included in the SCAQMD Final Localized Significance Threshold Methodology (LST Methodology) (17). The SCAQMD has established that impacts to air quality are significant if there is a potential to contribute or cause localized exceedances of the federal and/or state ambient air quality standards (NAAQS/CAAQS). Collectively, these are referred to as Localized Significance Thresholds (LSTs). The SCAQMD established LSTs in response to the SCAQMD Governing Board’s Environmental Justice Initiative I-4 3. LSTs represent the maximum emissions from a project that will not cause or contribute to an exceedance of the most stringent applicable federal or state ambient air quality standard at the sensitive receptor.
The SCAQMD states that lead agencies can use the LSTs as another indicator of significance in its
3 The purpose of SCAQMD’s Environmental Justice program is to ensure that everyone has the right to equal protection from air pollution and fair access to the decision-making process that works to improve the quality of air within their communities. Further, the SCAQMD defines Environmental Justice as “…equitable environmental policymaking and enforcement to protect the health of all residents, regardless of age, culture, ethnicity, gender, race, socioeconomic status, or geographic location, from the health effects of air pollution.” Attachment I.C

air quality impact analyses. It should be noted that SCAQMD also states that Projects that are statutorily or categorically exempt under CEQA would not be subject to LST analyses. Projects exempt from CEQA also include infill projects that meet the H&S Code provisions. As such, although not required for this Project, LST analysis is presented to further underscore that there are in fact no significant impacts associated with the Project.
The SCAQMD recommends that the nearest sensitive receptor be considered when determining the Project’s potential to cause an individual or cumulatively significant impact. The nearest land use where an individual could remain for 24 hours to the Project site has been used to determine localized construction and operational air quality impacts for emissions of PM10 and PM2.5 (since PM10 and PM2.5 thresholds are based on a 24-hour averaging time). The nearest receptor used for evaluation of localized impacts of PM10 and PM2.5 is location R4, represented by the existing residence at 11565 Downey Ave, adjacent west of the Project site. Receptors in the Project study area shown on Exhibit 2.
As previously stated, and consistent with LST Methodology, the nearest industrial/commercial use to the Project site is used to determine construction and operational LST air impacts for emissions of NOX and CO as the averaging periods for these pollutants are shorter (8 hours or less) and it is reasonable to assume that an individual could be present at these sites for periods of one to 8 hours. It should be noted that the existing residence (R4) is located at a closer distance than the nearest industrial/commercial use. As such, the same receptor will be used for evaluation of localized NOx and CO.
It should be noted that the LST Methodology explicitly states that “It is possible that a project may have receptors closer than 25 meters. Projects with boundaries located closer than 25 meters to the nearest receptor should use the LSTs for receptors located at 25 meters (17).” As such, for evaluation of localized PM10, PM2.5, NOx and CO, a 25-meter distance will be used.

Table 7 identifies the localized impacts at the nearest receptor location in the vicinity of the Project. Outputs from the model runs for construction LSTs are provided in Attachment A. For analytical purposes, emissions associated with peak demolition, site preparation, and grading activities are considered for purposes of LSTs since these phases represent the maximum localized emissions that would occur. Any other construction phases of development that overlap would result in lesser emissions and consequently lesser impacts than what is disclosed herein.
As shown in Table 7, emissions resulting from the Project construction will not exceed the numerical thresholds of significance established by the SCAQMD for any criteria pollutant. Thus, a less than significant impact would occur for localized Project-related construction-source emissions and no mitigation is required.

LOCALIZED OPERATIONAL EMISSIONS
The Project includes demolition of the existing structures on-site and developing an 18,808- square-foot gymnasium, 975-square-foot lobby/restrooms, and retrofitting of an approximate 7,625-square-foot existing gymnasium (total of 27,408 square feet). According to SCAQMD LST methodology, LSTs would apply to the operational phase of a proposed project, if the project includes stationary sources, or attracts mobile sources that may spend long periods queuing and idling at the site (e.g., transfer facilities and warehouse buildings). The proposed project does not include such uses, and thus, due to the lack of significant stationary source emissions, no LST analysis is needed for operations.

PROJECT GHG ANALYSIS
CLIMATE CHANGE SETTING
Global climate change (GCC) is the change in average meteorological conditions on the earth with respect to temperature, precipitation, and storms. The majority of scientists believe that the climate shift taking place since the Industrial Revolution is occurring at a quicker rate and magnitude than in the past. Scientific evidence suggests that GCC is the result of increased concentrations of GHGs in the earth’s atmosphere, including carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and fluorinated gases. The majority of scientists believe that this increased rate of climate change is the result of GHGs resulting from human activity and industrialization over the past 200 years.
An individual project like the proposed Project evaluated in this memo cannot generate enough GHG emissions to affect a discernible change in global climate. However, the proposed Project may participate in the potential for GCC by its incremental contribution of GHGs combined with the cumulative increase of all other sources of GHGs, which when taken together constitute potential influences on GCC. Because these changes may have serious environmental consequences, this memo will evaluate the potential for the proposed Project to have a significant effect upon the environment as a result of its potential contribution to the greenhouse effect.
GCC refers to the change in average meteorological conditions on the earth with respect to temperature, wind patterns, precipitation and storms. Global temperatures are regulated by naturally occurring atmospheric gases such as water vapor, CO2, N2O, CH4, hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and sulfur hexafluoride (SF6). These particular gases are important due to their residence time (duration they stay) in the atmosphere, which ranges from 10 years to more than 100 years. These gases allow solar radiation into the earth’s atmosphere, but prevent radiative heat from escaping, thus warming the earth’s atmosphere. GCC can occur naturally as it has in the past with the previous ice ages.
Gases that trap heat in the atmosphere are often referred to as GHGs. GHGs are released into the atmosphere by both natural and anthropogenic activity. Without the natural GHG effect, the earth’s average temperature would be approximately 61 degrees Fahrenheit (°F) cooler than it is currently. The cumulative accumulation of these gases in the earth’s atmosphere is considered to be the cause for the observed increase in the earth’s temperature.
For the purposes of this analysis, emissions of CO2, CH4, and N2O were evaluated because these gases are the primary contributors to GCC from development projects. Although there are other substances such as fluorinated gases that also contribute to GCC, these fluorinated gases were not evaluated as their sources are not well-defined and do not contain accepted emissions factors or methodology to accurately calculate these gases.
REGULATORY SETTING
Executive Order S-3-05
Former California Governor Arnold Schwarzenegger announced on June 1, 2005, through Executive Order S-3-05, the following reduction targets for GHG emissions:
• By 2010, reduce GHG emissions to 2000 levels.
Attachment I.C
Agenda Page 140
Tracy Zinn, T&B Planning, Inc.
May 14, 2024
15985-03 AQ & GHG Assessment
• By 2020, reduce GHG emissions to 1990 levels.
• By 2050, reduce GHG emissions to 80% below 1990 levels.
The 2050 reduction goal represents what some scientists believe is necessary to reach levels that will stabilize the climate. The 2020 goal was established to be a mid-term target. Because this is an executive order, the goals are not legally enforceable for local governments or the private sector.
Assembly Bill (AB) 32
The California State Legislature enacted AB 32, which requires that GHGs emitted in California be reduced to 1990 levels by the year 2020. “GHGs” as defined under AB 32 include CO2, CH4, N2O, hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and sulfur hexafluoride (SF6). Since AB 32 was enacted, a seventh chemical, nitrogen trifluoride, has also been added to the list of GHGs.
CARB is the state agency charged with monitoring and regulating sources of GHGs. Pursuant to AB 32, CARB adopted regulations to achieve the maximum technologically feasible and cost- effective GHG emission reductions. AB 32 states the following:
“Global warming poses a serious threat to the economic well-being, public health, natural resources, and the environment of California. The potential adverse impacts of global warming include the exacerbation of air quality problems, a reduction in the quality and supply of water to the state from the Sierra snowpack, a rise in sea levels resulting in the displacement of thousands of coastal businesses and residences, damage to marine ecosystems and the natural environment, and an increase in the incidences of infectious diseases, asthma, and other human health-related problems.”
CARB approved the 1990 GHG emissions level of 427 million metric ton of CO2 equivalent per year (MMTCO2e) on December 6, 2007 (18). Therefore, emissions generated in California in 2020 are required to be equal to or less than 427 MMTCO2e. Emissions in 2020 in a “business as usual” (BAU) scenario were estimated to be 596 MMTCO2e, which do not account for reductions from AB 32 regulations (19). At that level, a 28.4% reduction was required to achieve the 427 MMTCO2e 1990 inventory. In October 2010, CARB prepared an updated BAU 2020 forecast to account for the recession and slower forecasted growth. The forecasted inventory without the benefits of adopted regulation is now estimated at 545 MMTCO2e. Therefore, under the updated forecast, a
21.7% reduction from BAU is required to achieve 1990 levels (20).
Progress in Achieving AB 32 Targets and Remaining Reductions Required The State has made steady progress in implementing AB 32 and achieving targets included in Executive Order S-3-05. The progress is shown in updated emission inventories prepared by CARB for 2000 through 2012 (21). The State has achieved the Executive Order S-3-05 target for 2010 of reducing GHG emissions to 2000 levels. As shown below, the 2010 emission inventory achieved this target.
• 1990: 427 MMTCO2e (AB 32 2020 target)
• 2000: 463 MMTCO2e (an average 8% reduction needed to achieve 1990 base) • 2010: 450 MMTCO2e (an average 5% reduction needed to achieve 1990 base) Attachment I.C
Agenda Page 141
Tracy Zinn, T&B Planning, Inc.
May 14, 2024
15985-03 AQ & GHG Assessment
CARB has also made substantial progress in achieving its goal of achieving 1990 emissions levels by 2020. As described earlier in this section, CARB revised the 2020 BAU inventory forecast to account for new lower growth projections, which resulted in a new lower reduction from BAU to achieve the 1990 base. The previous reduction from 2020 BAU needed to achieve 1990 levels was 28.4% and the latest reduction from 2020 BAU is 21.7%. • 2020: 545 MMTCO2e BAU (an average 21.7% reduction from BAU needed to achieve 1990 base)
Senate Bill (SB) 32
On September 8, 2016, Governor Jerry Brown signed the SB 32 and its companion bill, AB 197. SB 32 requires the state to reduce statewide GHG emissions to 40% below 1990 levels by 2030, a reduction target that was first introduced in Executive Order B-30-15. The new legislation builds upon the AB 32 goal of 1990 levels by 2020 and provides an intermediate goal to achieving S-3- 05, which sets a statewide GHG reduction target of 80% below 1990 levels by 2050. AB 197 creates a legislative committee to oversee regulators to ensure that CARB not only responds to the Governor, but also the Legislature (22).
AB 197
A condition of approval for SB 32 was the passage of AB 197. AB 197 requires that CARB consider the social costs of GHG emissions and prioritize direct reductions in GHG emissions at mobile sources and large stationary sources. AB 197 also gives the California legislature more oversight over CARB through the addition of two legislatively appointed members to the CARB Board and the establishment a legislative committee to make recommendations about CARB programs to the legislature.
Executive Order B-55-18 and SB 100
Executive Order B-55-18 and SB 100. SB 100 and Executive Order B-55-18 were signed by Governor Brown on September 10, 2018. Under the existing RPS, 25% of retail sales are required to be from renewable sources by December 31, 2016, 33% by December 31, 2020, 40% by December 31, 2024, 45% by December 31, 2027, and 50% by December 31, 2030. SB 100 raises California’s RPS requirement to 50% renewable resources target by December 31, 2026, and to achieve a 60% target by December 31, 2030. SB 100 also requires that retail sellers and local publicly owned electric utilities procure a minimum quantity of electricity products from eligible renewable energy resources so that the total kilowatt hours of those products sold to their retail end-use customers achieve 44% of retail sales by December 31, 2024, 52% by December 31, 2027, and 60% by December 31, 2030. In addition to targets under AB 32 and SB 32, Executive Order B- 55-18 establishes a carbon neutrality goal for the state of California by 2045; and sets a goal to maintain net negative emissions thereafter. The Executive Order directs the California Natural Resources Agency (CNRA), California Environmental Protection Agency (CalEPA), the Department of Food and Agriculture (CDFA), and CARB to include sequestration targets in the Natural and Working Lands Climate Change Implementation Plan consistent with the carbon neutrality goal.
Title 24 California Code of Regulations (CCR)
California Code of Regulations (CCR) Title 24 Part 6: The California Energy Code was first adopted in 1978 in response to a legislative mandate to reduce California’s energy consumption.
Attachment I.C
Agenda Page 142

May 14, 2024
15985-03 AQ & GHG Assessment
The standards are updated periodically to allow consideration and possible incorporation of new energy efficient technologies and methods. CCR, Title 24, Part 11: California Green Building Standards Code (CALGreen) is a comprehensive and uniform regulatory code for all residential, industrial, commercial, and school buildings that went in effect on August 1, 2009, and is administered by the California Building Standards Commission.
CALGreen is updated on a regular basis, with the most recent approved update consisting of the 2022 California Green Building Code Standards that became effective on January 1, 2023 4. As construction of the Project is anticipated to be completed in 2025, the Project would be required to comply with the Title 24 standards in place at that time.
SCAQMD
SCAQMD is the agency responsible for air quality planning and regulation in the SCAB. The SCAQMD addresses the impacts to climate change of projects subject to SCAQMD permit as a lead agency if they are the only agency having discretionary approval for the project and acts as a responsible agency when a land use agency must also approve discretionary permits for the project. The SCAQMD acts as an expert commenting agency for impacts to air quality. This expertise carries over to GHG emissions, so the agency helps local land use agencies through the development of models and emission thresholds that can be used to address GHG emissions.
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 SCAB. The Working Group developed several different options that are contained in the SCAQMD Draft Guidance Document – Interim CEQA GHG Significance Threshold, that could be applied by lead agencies. The working group has not provided additional guidance since the release of the interim guidance in 2008. The SCAQMD Board has not approved the thresholds; however, the Guidance Document provides substantial evidence supporting the approaches to significance of GHG emissions that can be considered by the lead agency in adopting its own threshold. The current interim thresholds consist of the following tiered approach:
• Tier 1 consists of evaluating whether or not the project qualifies for any applicable exemption under CEQA.
• Tier 2 consists of determining whether the project is consistent with a GHG reduction plan. If a project is consistent with a qualifying local GHG reduction plan, it does not have significant GHG emissions.
• Tier 3 consists of screening values, which the lead agency can choose, but must be consistent with all projects within its jurisdiction. A project’s construction emissions are averaged over 30 years and are added to the project’s operational emissions. If a project’s emissions are below one of the following screening thresholds, then the project is less than significant:
o Residential and commercial land use: 3,000 metric ton of CO2 equivalent (MTCO2e/yr)
4 The 2022 California Green Building Standard Code will be published July 1, 2022.
Attachment I.C
Agenda Page 143
Tracy Zinn, T&B Planning, Inc.
May 14, 2024
15985-03 AQ & GHG Assessment
o Industrial land use: 10,000 MTCO2e/yr
o Based on land use type: residential: 3,500 MTCO2e/yr; commercial: 1,400 MTCO2e/yr; or mixed use: 3,000 MTCO2e/yr
• Tier 4 has the following options:
o Option 1: Reduce Business-as-Usual (BAU) emissions by a certain percentage; this percentage is currently undefined.
o Option 2: Early implementation of applicable AB 32 Scoping Plan measures o Option 3: 2020 target for service populations (SP), which includes residents and employees: 4.8 MTCO2e per SP per year for projects and 6.6 MTCO2e per SP per year for plans;
o Option 3, 2035 target: 3.0 MTCO2e per SP per year for projects and 4.1 MTCO2e per SP per year for plans
• Tier 5 involves mitigation offsets to achieve target significance threshold.
The SCAQMD’s interim thresholds used the Executive Order S-3-05-year 2050 goal as the basis for the Tier 3 screening level. Achieving the Executive Order’s objective would contribute to worldwide efforts to cap CO2 concentrations at 450 ppm, thus stabilizing global climate.
SCAQMD only has authority over GHG emissions from development projects that include air quality permits. At this time, it is unknown if the project would include stationary sources of emissions subject to SCAQMD permits. Notwithstanding, if the Project requires a stationary permit, it would be subject to the applicable SCAQMD regulations.
SCAQMD Regulation XXVII, adopted in 2009 includes the following rules:
• Rule 2700 defines terms and post global warming potentials. • Rule 2701, Southern California (SoCal) Climate Solutions Exchange, establishes a voluntary program to encourage, quantify, and certify voluntary, high quality certified GHG emission reductions in the SCAQMD.
• Rule 2702, GHG Reduction Program created a program to produce GHG emission reductions within the SCAQMD. The SCAQMD will fund projects through contracts in response to requests for proposals or purchase reductions from other parties.
SCAQMD is the agency responsible for air quality planning and regulation in the SCAB. The SCAQMD addresses the impacts to climate change of projects subject to SCAQMD permit as a lead agency if they are the only agency having discretionary approval for the project and acts as a responsible agency when a land use agency must also approve discretionary permits for the project. The SCAQMD acts as an expert commenting agency for impacts to air quality. This expertise carries over to GHG emissions, so the agency helps local land use agencies through the development of models and emission thresholds that can be used to address GHG emissions.

PROJECT NET NEW GHG EMISSIONS – COMPARISON TO EXISTING BUILDING Table 12 shows the Project is anticipated to generate less GHG emissions per day as compared to emissions generated by the existing building, additionally; the proposed Projects emissions would be less than the applicable thresholds.
TABLE 12: PROJECT NET NEW GHG EMISSIONS
Emission Source Total CO2e
Proposed Project 730.60
Existing Building 1,194.31
Net Emissions (Proposed – Existing) -463.70
The Project would result in a net decrease of approximately 463.70 MTCO2e/yr; the proposed Project would not exceed the SCAQMD’s numeric threshold of 3,000 MTCO2e/yr. Thus, the Project would result in a less than significant impact with respect to GHG emissions and no mitigation is required.
CONCLUSION
Results of the assessment indicate that the Project is not anticipated to result in a significant impact during construction or operational activities associated with air quality and GHG and no mitigation is required.

15985 - YMCA Downey (Proposed) Detailed Report, 5/2/2024 43 / 49
Cal-Adapt midcentury 2040–2059 average projections for four hazards are reported below for your project location. These are under Representation Concentration Pathway (RCP) 8.5 which assumes GHG emissions will continue to rise strongly through 2050 and then plateau around 2100.
Climate Hazard Result for Project Location Unit
Temperature and Extreme Heat 8.91 annual days of extreme heat Extreme Precipitation 4.70 annual days with precipitation above 20 mm Sea Level Rise —meters of inundation depth
Wildfire 0.00 annual hectares burned
Temperature and Extreme Heat data are for grid cell in which your project are located. The projection is based on the 98th historical percentile of daily maximum/minimum temperatures from observed historical data (32 climate model ensemble from Cal-Adapt, 2040–2059 average under RCP 8.5). Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi.
Extreme Precipitation data are for the grid cell in which your project are located. The threshold of 20 mm is equivalent to about ¾ an inch of rain, which would be light to moderate rainfall if received over a full day or heavy rain if received over a period of 2 to 4 hours. Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi.
Sea Level Rise data are for the grid cell in which your project are located. The projections are from Radke et al. (2017), as reported in Cal-Adapt (Radke et al., 2017, CEC-500-2017-008), and consider inundation location and depth for the San Francisco Bay, the Sacramento-San Joaquin River Delta and California coast resulting different increments of sea level rise coupled with extreme storm events.
Users may select from four scenarios to view the range in potential inundation depth for the grid cell. The four scenarios are: No rise, 0.5 meter, 1.0 meter, 1.41 meters Wildfire data are for the grid cell in which your project are located. The projections are from UC Davis, as reported in Cal-Adapt (2040–2059 average under RCP 8.5), and consider historical data of climate, vegetation,population density, and large (> 400 ha) fire history. Users may select from four model simulations to view the range in potential wildfire probabilities for the grid cell. The four simulations make different assumptions about expected rainfall and temperature are: Warmer/drier (HadGEM2-ES), Cooler/wetter (CNRM-CM5), Average conditions (CanESM2), Range of different rainfall and temperature possibilities (MIROC5). Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi.

The adaptive capacity of a project refers to its ability to manage and reduce vulnerabilities from projected climate hazards. Adaptive capacity is rated on a scale of 1 to 5, with a score of 5 representing the greatest ability to adapt.
The overall vulnerability scores are calculated based on the potential impacts and adaptive capacity assessments for each hazard. Scores do not include implementation of climate risk reduction measures.

6. Climate Risk Detailed Report
6.1. Climate Risk Summary
Cal-Adapt midcentury 2040–2059 average projections for four hazards are reported below for your project location. These are under Representation Concentration Pathway (RCP) 8.5 which assumes GHG emissions will continue to rise strongly through 2050 and then plateau around 2100.
Climate Hazard Result for Project Location Unit
Temperature and Extreme Heat 8.91 annual days of extreme heat Extreme Precipitation 4.70 annual days with precipitation above 20 mm Sea Level Rise —meters of inundation depth
Wildfire 0.00 annual hectares burned
Temperature and Extreme Heat data are for grid cell in which your project are located. The projection is based on the 98th historical percentile of daily maximum/minimum temperatures from observed historical data (32 climate model ensemble from Cal-Adapt, 2040–2059 average under RCP 8.5). Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi.
Extreme Precipitation data are for the grid cell in which your project are located. The threshold of 20 mm is equivalent to about ¾ an inch of rain, which would be light to moderate rainfall if received over a full day or heavy rain if received over a period of 2 to 4 hours. Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi.

Agenda Page 222
15985 - YMCA Downey (Existing) Detailed Report, 5/1/2024 24 / 30
Sea Level Rise data are for the grid cell in which your project are located. The projections are from Radke et al. (2017), as reported in Cal-Adapt (Radke et al., 2017, CEC-500-2017-008), and consider inundation location and depth for the San Francisco Bay, the Sacramento-San Joaquin River Delta and California coast resulting different increments of sea level rise coupled with extreme storm events.
Users may select from four scenarios to view the range in potential inundation depth for the grid cell. The four scenarios are: No rise, 0.5 meter, 1.0 meter, 1.41 meters Wildfire data are for the grid cell in which your project are located. The projections are from UC Davis, as reported in Cal-Adapt (2040–2059 average under RCP 8.5), and consider historical data of climate, vegetation,population density, and large (> 400 ha) fire history. Users may select from four model simulations to view the range in potential wildfire probabilities for the grid cell. The four simulations make different assumptions about expected rainfall and temperature are: Warmer/drier (HadGEM2-ES), Cooler/wetter (CNRM-CM5), Average conditions (CanESM2), Range of different rainfall and temperature possibilities (MIROC5). Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi.
6.2. Initial Climate Risk Scores
Climate Hazard Exposure Score Sensitivity Score Adaptive Capacity Score Vulnerability Score Temperature and Extreme Heat 1 0 0 N/A
Extreme Precipitation N/A N/A N/A N/A

Flooding N/A N/A N/A N/A
Drought N/A N/A N/A N/A
Snowpack Reduction N/A N/A N/A N/A
Air Quality Degradation 0 0 0 N/A
The sensitivity score reflects the extent to which a project would be adversely affected by exposure to a climate hazard. Exposure is rated on a scale of 1 to 5, with a score of 5 representing the greatest exposure.
The adaptive capacity of a project refers to its ability to manage and reduce vulnerabilities from projected climate hazards. Adaptive capacity is rated on a scale of 1 to 5, with a score of 5 representing the greatest ability to adapt.
The overall vulnerability scores are calculated based on the potential impacts and adaptive capacity assessments for each hazard. Scores do not include implementation of climate risk reduction measures.

MANAGEMENT SUMMARY/ABSTRACT
In response to a request from the applicant, a cultural resources study was conducted by BFSA Environmental, a Perennial Company (BFSA), for the proposed YMCA Downey Project.
The proposed 2.16-acre project is located southwest of the intersection of Downey Avenue and Arnett Street and includes 11531 Downey Avenue, 11525 Downey Avenue, and 8268 Arnett Street, in the city of Downey, Los Angeles County, California (Assessor’s Parcel Numbers [APNs] 6255-013-032, -033, and -034). The project is situated within the unsectioned former Santa Gertrudes (McFarland and Downey) Rancho, Township 3 South, Range 12 West, as shown on the U.S. Geological Survey (USGS) South Gate, California Quadrangle. Currently, the property contains four historic buildings including the YMCA recreational building at 11531 Downey Avenue (built 1963), one commercial/office building at 11525 Downey Avenue (built 1965), and one single-family residence with a detached garage at 8268 Arnett Street (built between 1947 and 1950). As proposed, the project plans to clear most of the property for the development of a newly designed YMCA campus. The project proposes to demolish the buildings at 11525 Downey Avenue and 8268 Arnett Street. Likewise, most of the current YMCA recreational building at 11531 Downey Avenue will be demolished; however, approximately 7,625 square feet of the building will remain and be retrofitted.
The purpose of this investigation was to locate and record any cultural resources within the project and subsequently evaluate any resources as part of the City of Downey environmental review process conducted in compliance with the California Environmental Quality Act (CEQA).
The archaeological investigation of the project also includes the review of an archaeological records search performed at the South Central Coastal Information Center (SCCIC) at California State University, Fullerton (CSU Fullerton), in order to assess previous archaeological studies and identify any previously recorded archaeological sites within the project or in the immediate vicinity. According to the records search results, eight resources (all historic) have been recorded within one mile of the project, one of which (P-19-190639) is recorded within the subject property.
Site P-19-190639 is the YMCA recreational building at 11531 Downey Avenue. The building was recorded and evaluated by K.A. Crawford of Michael Brandman Associates in 2013.
Crawford concluded that the design, materials, and workmanship of the structure had been altered by a major addition to the northern portion of the building in the late 1970s. Subsequently, Crawford evaluated the building as not eligible for the National Register of Historic Places (NRHP).
A Sacred Lands File (SLF) search was also requested from the Native American Heritage Commission (NAHC). The search was returned with negative results for any recorded Native American sacred sites or locations of religious or ceremonial importance within the project vicinity.
BFSA staff archaeologist Mary Chitjian conducted the cultural resources survey of the YMCA Downey Project on April 15, 2024. The survey was an intensive reconnaissance consisting of a series of survey transects across the project. While the entire project was accessible, ground Attachment I.D

surface visibility was poor as the subject property is entirely developed containing the YMCA recreational building at 11531 Downey Avenue, a commercial/office building at 11525 Downey Avenue, one single-family residence with a detached garage at 8268 Arnett Street, along with associated hardscape and landscaping. No archaeological resources were identified during the survey. However, the buidings and structures within the project boundaries were constructed between 1947 and 1965 and, therefore, meet the age threshold under the National Register (36 CFR [Code of Federal Regulations] 60.4) and the California Code of Regulations (CCR § 4852) to require evaluations of potential eligibility to the California Register of Historical Resources (CRHR). Because the historic buildings and structures will be impacted by development, the evaluation of the buildings is required to address potentially significant impacts to potential historical resources. The structures were evaluated by BFSA as part of this study.
While the buildings and structures within the property meet the 50-year age threshold for evaluation, they are evaluated as not eligible for the CRHR. None of the properties are associated with significant individuals, significant architectural examples, or are able to provide more information regarding the history of Downey or the state of California. Because the buildings located at 8268 Arnett Street and 11525 and 11531 Downey Avenue are not eligible for listing on the CRHR, no site-specific mitigation measures are required for any future alterations or planned demolition of the buildings.
Although the historic buildings were evaluated as not CEQA-significant, the potential exists that unidentified cultural resources may be present that are related to the historic use of the area since prior to 1928. Based upon this potential, monitoring of grading is recommended to prevent the inadvertent destruction of any potentially important cultural deposits that were not observed or detected during the current cultural resources study. Should potentially significant cultural deposits be discovered, mitigation measures should be implemented to reduce the effects of the grading impacts. If prehistoric cultural resources are discovered, Native American monitoring would be required for all subsequent earthwork for the project. As a part of this study, a copy of this report will be submitted to the SCCIC at CSU Fullerton. Qualifications of key BFSA staff involved in the preparation of this report can be found within Appendix A.

1.0 INTRODUCTION
1.1 Project Description
The cultural resources study program for the YMCA Downey Project was conducted in order to comply with CEQA and City of Downey environmental compliance procedures. The
2.16-acre project is located southwest of the intersection of Downey Avenue and Arnett Street and includes 11531 Downey Avenue, 11525 Downey Avenue, and 8268 Arnett Street, in the city of Downey, Los Angeles County, California (APNs 6255-013-032, -033, and -034) (Figure 1.1–1).
The project is situated within the unsectioned former Santa Gertrudes (McFarland and Downey) Rancho, Township 3 South, Range 12 West, as shown on the USGS South Gate, California Quadrangle (Figure 1.1–2). Currently, the property contains four historic buildings, including the YMCA recreational building at 11531 Downey Avenue (built 1963), one commercial/office building at 11525 Downey Avenue (built 1965), and one single-family residence with a detached garage at 8268 Arnett Street (built between 1947 and 1950). As proposed, the project plans to clear most of the property for the development of a newly designed YMCA campus. The project proposes to demolish the buildings at 11525 Downey Avenue and 8268 Arnett Street. Likewise, most of the current YMCA building at 11531 Downey Avenue will be demolished; however, approximately 7,625 square feet of the building will remain and be retrofitted (Figure 1.1–3).
The decision to request this investigation was based upon cultural resource sensitivity of the locality as suggested by known site density and predictive modeling. Sensitivity for cultural resources in a given area is usually indicated by known settlement patterns, which, in southeastern Los Angeles County, were focused around freshwater resources and a food supply.
1.2 Environmental Setting
The YMCA Downey Project is generally located in southeastern Los Angeles County in the city of Downey. Geologically, the project is located within the Central Basin of the larger Los Angeles Basin, a large structural sedimentary basin bounded and cut through by several active fault systems in the Los Angeles metropolitan area (Hillhouse et al. 2002). As mapped by Saucedo et al. (2016), the project is underlain by undivided sandy, Holocene-aged young alluvium. The specific soil types found within the property are characterized as Urban land-Hueneme, drained- San Emigdio complex (NRCS 2019).
Currently, the subject property is fully developed containing the YMCA recreational building at 11531 Downey Avenue (built 1963), one commercial/office building at 11525 Downey Avenue (built 1965), one single-family residence with a detached garage at 8268 Arnett Street (built between 1947 and 1950), along with associated parking, hardscape, and landscaping.
Historically, many of the water sources in this area have been channelized, such as the Los Angeles and the San Gabriel rivers, which are situated approximately two miles west and one-and-one-half miles east, respectively, of the subject property.

1.3 Cultural Setting
The oldest directly dated human remains from coastal southern California are those of the “Los Angeles Man.” These remains were dated to 26,000 years before the present (YBP) using amino acid racemization and radiocarbon techniques; however, later dates using the more reliable accelerator mass spectrometry method determined that that date was exaggerated (Altschul and Grenda 2002). Evidence of early Holocene occupation along the southern California coast and islands has been increasing, including the Arlington Springs Site on Santa Rosa Island, the Arlington Springs and Daisy Cave Site on San Miguel Island, and Eel Point on San Clemente Island (Altschul and Grenda 2002). These sites appear to suggest an early Holocene migration southward along the coast. The fact that these early sites are present on the islands, but have yet to be found on the coast, lends support for the view that rising sea levels have probably destroyed early Holocene coastal sites. This period covers Wallace’s Period I or Early Man cultural sequences (Moratto 1984).
Due to a rapid and prolonged rise in sea level during the early Holocene, between 10,000 and 6,000 YBP, many archaeological sites associated with this early period along coastal southern California were probably destroyed or obscured by sea level advancement or sedimentation (Carbone 1991). The increase in sea levels probably forced a shift from rocky shore resources (shellfish) to estuarine and lagoon resources with a more varied economy, including marine, avian, and terrestrial species (Carbone 1991). The natural history of the Ballona Wetlands has been constructed based upon stratigraphic analysis (Altschul and Grenda 2002). The results suggest that after sea levels stabilized around 7,000 YBP, a variety of depositional environments were created that reshaped the landscape on which inhabitants were living. By 6,200 YBP, a spit of sand migrated across the mouth of the coastal inlet, creating a shallow lagoon; this area appears to have been visited by Native Americans at about this time (Altschul and Grenda 2002). As sedimentation increased, the lagoon gradually decreased in size. Because tidal waters were blocked, the lagoon shifted from marine to fresh water. As the lagoon gradually turned into tidal marshes and estuarine environments became well established, habitation along the edges of the water source increased. Based upon archaeological evidence, permanent occupation in the area appears to have occurred by 3,000 years ago and lasted until the Protohistoric Period (Altschul and Grenda 2002).
Human adaptations during the middle Holocene (circa 8,000 to 5,000 YBP) in the Los Angeles Basin are characterized by an abundance of grinding implements (specifically manos and metates). Rising sea levels began to stabilize and temperatures reached a thermal optimum at about 6,800 YBP (Altschul and Grenda 2002). Archaeological sites dating to this period tend to be located in grasslands and sagebrush communities on elevated landforms some distance from the shore (Altschul and Grenda 2002). Other characteristics of this period include stone ornaments, large projectile points, and charm stones, while bone and shell tools, ornamentation, and trade items are rare. Sites from this period appear to have consisted of semisedentary settlements with populations ranging from 15 to 100 people, primarily located in the coastal zone and along interior drainages. During this time, the Ballona region was first occupied (Altschul and Attachment I.D
Agenda Page 241
Cultural Resources Study for the YMCA Downey Project

Grenda 2002). This period covers Warren’s Encinitas Tradition and Wallace’s Period II (or Milling Stone Horizon) cultural sequences (Moratto 1984). The later date given for the Milling Stone Horizon varies to as late as 3,000 YBP. The lack of trade items such as obsidian and steatite are often used to attribute a site to this period.
A shift appears to have occurred in the later part of the middle Holocene, between 5,000 and 3,350 YBP (Altschul and Grenda 2002). Mortars and pestles were more common, which suggests that acorns were being exploited as an important part of the prehistoric diet in southern California. Other characteristics of this period include variations of large stemmed, leaf-shaped, and side-notched points, basket-hopper mortars, a variety of stone tools, bone tools, and shell ornamentation. This period corresponds to Warren’s (1968) Campbell Tradition and Wallace’s (1955, 1978) Period III, or Intermediate Horizon; however, the ending date for these periods varies to as late as approximately 1,000 YBP (Moratto 1984). There appears to have been a general shift from a plant-based economy to one that was more diversified, being a generalized hunting/fishing/gathering adaptation, possibly in response to Altithermal conditions (8,000 to 3,000 YBP) (Altschul and Grenda 2002). Evidence suggests that coastal populations placed an understandable emphasis upon marine resources, while the focus of inland occupation was upon hunting land mammals. Trade goods became more common during this period, suggesting intensified regional economic exchange and interaction. Finally, villages appear to have been more permanent during the Intermediate Horizon, closely resembling the later settlement pattern of the region (Altschul and Grenda 2002). By 3,000 YBP, the Ballona region to the north was intensively and relatively permanently occupied. Some researchers suggest that the increasing population density during the late to middle Holocene did not necessarily grow out of the local population, but was a result of a desert migration, perhaps as early as 3,000 YBP (Altschul and Grenda 2002).
During the late Holocene, population size and density increased dramatically, calling for an even more diversified economy (Altschul and Grenda 2002). This period is Wallace’s Period IV, or Late Horizon. Ethnographic data, the first of which was from Spanish explorers and missionaries, indicates that the Gabrielino (Tongva) were the major tribe established in the project area. The Spanish attributed this name to the Native Americans in the area served by the San Gabriel Mission. Gabrielino territory included the watersheds of the San Gabriel, Santa Ana, and Los Angeles rivers, portions of the Santa Monica and Santa Ana mountains, the Los Angeles basin, the coast from Aliso Creek to Topanga Creek, and the San Clemente, San Nicolas, and Santa Catalina islands (Moratto 1984). The Gabrielino spoke a Cupan language that was part of the Shoshonean or Takic family of Uto-Aztecan linguistic stock; these linguistic ties united a disperse ethnic group occupying 1,500 square miles in the Los Angeles basin region (Altschul and Grenda 2002). Interestingly, this language stock was different from that of the Chumash to the north in the Santa Barbara region, as well as from the Kumeyaay (Tipai and Ipai) in the San Diego region, both of which spoke languages of the Hokan stock (although using different dialects).
Ethnographic data states that the Gabrielino were hunters and gatherers whose food sources included acorns, seeds, marine mollusks, fish, and mammals; archaeological sites support this data, Attachment I.D

with evidence of hunting, gathering, processing, and storage implements including arrow points, fishhooks, scrapers, grinding stones, and basketry awls (Altschul and Grenda 2002). Santa Catalina Island provided a valuable source of steatite for the Gabrielino, which they quarried and traded to other groups (Heizer and Treganza 1972; Moratto 1984). About 50 to 100 permanent villages are estimated to have been in existence at the time of European contact, most of which were located along lowland rivers and streams and along sheltered areas of the coast (Moratto 1984). Smaller satellite villages and resource extraction sites were located between larger villages.
Village sites contained varying types of structures, including houses, sweathouses, and ceremonial huts (Bean and Smith 1978). Artistic items included shells set in asphaltum, carvings, painting, steatite, and baskets (Moratto 1984). Settlements were often located at the intersection of two or more ecozones, thus increasing the variety of resources that were immediately accessible (Moratto 1984). Offshore fishing and hunting were accomplished with the use of plank boats, while shellfish and birds were collected along the coast. At the time of European contact, the Gabrielino, second only to the Chumash, were the wealthiest, most populous, and most powerful ethnic group in southern California (Bean and Smith 1978; Moratto 1984).
As with other Native American populations in southern California, the arrival of the Spanish drastically changed life for the Gabrielino. Incorporation into the mission system disrupted their culture and changed their subsistence practices (Altschul and Grenda 2002).
Ranchos were established throughout the area, often in major drainages where Native American villages tended to be located. By the early 1800s, Mission San Gabriel had expanded its holdings for grazing to include much of the former Gabrielino territory (Altschul and Grenda 2002).
Eventually, widespread relocation of Native American groups occurred, resulting in further disruption of the native lifeways. With the introduction of Euro-American diseases, the Gabrielino and other groups of southern California experienced drastic population declines. In the early 1860s, a smallpox epidemic nearly wiped out the remaining Gabrielino population (Moratto 1984).
While people of Gabrielino descent still live in the Los Angeles area, the Gabrielino were no longer listed as a culturally identifiable group in the 1900 Federal Census (Bean and Smith 1978; Moratto 1984).
General History of the Los Angeles Area
The historic background of the project area began with the Spanish colonization of Alta California. The first Spanish colonizing expedition reached southern California in 1769 with the intention of converting and civilizing the indigenous populations, as well as expanding the knowledge of and access to new resources in the region (Brigandi 1998). As a result, by the late eighteenth century, a large portion of southern California was overseen by Mission San Luis Rey (San Diego County), Mission San Juan Capistrano (Orange County), and Mission San Gabriel (Los Angeles County), who began colonizing the region and surrounding areas (Chapman 1921).
Up until this time, the only known way to feasibly travel from Sonora to Alta California was by sea. In 1774, Juan Bautista de Anza, an army captain at Tubac, requested and was given permission by the governor of the Mexican State of Sonora to establish a n overland route from Attachment I.D
Agenda Page 243

Sonora to Monterey (Chapman 1921). In doing so, Juan Bautista de Anza passed through Riverside County and described the area in writing for the first time (Caughey 1970; Chapman 1921). In 1797, Father Presidente Lausen (of Mission San Diego de Alcalá), Father Norberto de Santiago, and Corporal Pedro Lisalde (of Mission San Juan Capistrano) led an expedition through southwestern Riverside County in search of a new mission site to establish a presence between San Diego and San Juan Capistrano (Engelhardt 1921). Their efforts ultimately resulted in the establishment of Mission San Luis Rey in Oceanside, California.
On September 8, 1771, Father Pedro Cambón and Father Angel Somera established the Mission San Gabriel de Arcángel near the present-day city of Montebello. In 1775, the mission was moved to its current location in San Gabriel due to better agricultural lands. This mission marked the first sustained European occupation of the Los Angeles County area. Mission San Gabriel, despite a slow start which was partially due to misconduct by Spanish soldiers, eventually became so prosperous that it was known as “The Queen of the Missions” (Johnson et al. 1972).
Each mission gained power through the support of a large, subjugated Native American workforce. As the missions grew, livestock holdings increased and became increasingly vulnerable to theft. In order to protect their interests, the southern California missions began expanding inland to try and provide additional security (Beattie and Beattie 1939; Caughey 1970).
In order to meet their needs, the Spaniards embarked on a formal expedition in 1806 to find potential locations within what is now the San Bernardino Valley. As a result, by 1810, Father Francisco Dumetz of Mission San Gabriel had succeeded in establishing a religious site, or capilla, at a Cahuilla rancheria called Guachama (Beattie and Beattie 1939). San Bernardino Valley received its name from this site, which was dedicated to San Bernardino de Siena by Father Dumetz. The Guachama rancheria was located in present-day Bryn Mawr in San Bernardino County.
These early colonization efforts were followed by establishment of estancias at Puente (circa 1816) and San Bernardino (circa 1819) near Guachama (Beattie and Beattie 1939). These efforts were soon mirrored by Spaniards from Mission San Luis Rey, who in t urn established a presence in what is now Lake Elsinore, Temecula, and Murrieta (Chapman 1921). The indigenous groups who occupied these lands were recruited by missionaries, converted, and put to work in the missions (Pourade 1964). Throughout this period, the Native American populations were decimated by introduced diseases, a drastic shift in diet resulting in poor nutrition, and social conflicts due to the introduction of an entirely new social order (Cook 1976).
The pueblo that eventually became the city of Los Angeles was established in 1781. During this period, Spain also deeded ranchos to prominent citizens and soldiers (though very few in comparison to the later Mexican Period). One such rancho, Rancho San P edro, was deeded to soldier Juan Jose Dominguez in 1784 and comprised 75,000 acres, encompassing the modern South Bay region from the Los Angeles River on the east to the Pacific Ocean on the west.
The area that became Los Angeles County saw an increase in European settlement during the Mexican Period, largely due to the many land grants (ranchos) to Mexican citizens by various governors. The period ended in early January of 1847, when Mexican forces fought the combined Attachment I.D

United States Army and Navy forces in the Battle of the San Gabriel River on January 8, 1847 and the Battle of La Mesa on January 9, 1847 (Nevin 1978). On January 10, 1847, leaders of the pueblo of Los Angeles surrendered peacefully after Mexican General Jose Maria Flores withdrew his forces. Shortly thereafter, newly appointed Mexican Military Commander of California, Andrés Pico, surrendered all of Alta California to United States Army Lieutenant Colonel John C.
Fremont in the Treaty of Cahuenga (Nevin 1978).
Treatment of Native Americans grew worse during the Rancho Period. Most were forced off their land or put to work on the now privately-owned ranchos, most often as slave labor. In light of the brutal ranchos, the degree to which Native Americans had become dependent upon the mission system is evident when, in 1838, a group of Native Americans from Mission San Luis Rey petitioned government officials in San Diego to relieve suffering at the hands of the rancheros:
We have suffered incalculable losses, for some of which we are in part to be blamed for because many of us have abandoned the Mission … We plead and beseech you … to grant us a Rev. Father for this place. We have been accustomed to the Rev.
Fathers and to their manner of managing the duties. We labored under their intelligent directions, and we were obedient to the Fathers according to the regulations, because we considered it as good for us. (Brigandi 1998:21)
Native American culture had been disrupted to the point where they could no longer rely upon prehistoric subsistence and social patterns. Not only does this illustrate how dependent the Native Americans had become upon the missionaries, but also indicates a marked contrast in the way the Spanish treated the Native Americans compared to the Mexican and United States ranchers. Spanish colonialism (missions) is based upon utilizing human resources while integrating them into their society. The Mexican and American ranchers did not accept Native Americans into their social order and used them specifically for the extraction of labor, resources, and profit. Rather than being incorporated, they were either subjugated or exterminated (Cook 1976).
Settlement of the Los Angeles region accelerated during the early American Period. The county was established on February 18, 1850. It was one of 27 counties established in the months prior to California becoming a state. Many ranchos in the county were sold or otherwise acquired by Americans, and most were subdivided into agricultural parcels or towns. Nonetheless, ranching retained its importance, and by the late 1860s, Los Angeles was one of the top dairy production centers in the country (Rolle 1963). In 1854, the United States Congress agreed to let San Pedro become an official port of entry, and by the 1880s, the railroads had established networks throughout the county, resulting in fast and affordable shipment of goods, as well as a means to transport new residents to the booming region (Dumke 1944). New residents included many health-seekers drawn to the area by the fabled climate in the 1870s to the 1880s (Baur 1959). In 1876, the county had a population of 30,000 (Dumke 1944:7); by 1900, it had reached 100,000.
In the early to mid-1900s, population growth accelerated due to industry associated with Attachment I.D

both world wars, as well as emigration from the Midwest “dust bowl” states during the Great Depression. The county became one of the most densely occupied areas in the United States. The county’s mild climate and successful economy continued to draw new residents in the late 1900s, and much of the county transformed from ranches and farms into residential subdivisions surrounding commercial and industrial centers. Hollywood’s development into the entertainment capital of the world and southern California’s booming aerospace industry were key factors in the county’s growth.
Brief History of Downey
The project is located within the former Rancho Santa Gertrudes, which was subdivided from the original Land Grant of Rancho Los Nietos. Governor Pedro Fages awarded a large land grant to Corporal José Manuel Nieto. At first it was called La Zanja, but later it was known simply as Rancho Los Nietos. The Rancho was one of the largest granted and encompassed approximately 300,000 acres, spanning from Puente Hills to the Pacific Ocean. After Nieto passed away in 1834, the Rancho was subdivided by his heirs into five smaller ranchos, which included Las Bolsas, Los Alamitos, Los Cerritos, Los Coyotes, and Santa Gertrudes. Rancho Santa Gertrudes was passed to Josefa Cota, the widow of Antonio Maria Nieto, son of Manuel Nieto. Lemuel Carpenter bought the Rancho from Josefa Cota in 1843, Capenter was married to Cota’s niece. Later, Carpenter ended up in debt to John G. Downey and committed suicide in 1859. The rancho was the sold at auction to Downey and James P. McFarland (Santa Fe Springs Library n.d.).
John Downey was an Irish Immigrant who traveled to California from the east coast in search of gold. Downey was governor of California between 1860 and 1862. At the end of his gubernatorial term, he returned to Los Angeles. In 1865, Downey began subdividing Rancho Santa Gertrudes into small farm lots (City of Downey n.d.):
Governor Downey’s acquisition of this rancho marked a shift in the primary use of the area. Rancho Gertrudes had been open cattle range; it was now put to the plow, and an agricultural/citrus started that was to prosper for almost ninety years. John Downey divided the land into agricultural plots and new residents fleeing the ravages of the Civil War developed a community. By 1873, the Southern Pacific Railroad built a line to this area between two settled areas called Gallatin and College Settlement and laid the foundations for a future city which marked a new era of prosperity for what became known as Downey City.
The Downey area grew in sporadic leaps. The California Goldrush, the Civil War, World War I; each event brought new residents to the town. The Second World War laid the foundation for establishing a strong aviation industry in Downey; and by the 1950’s this industry had become a significant economic factor for Downey.

On December 17, 1956 the community of Downey, having a population of approximately 90,000 people living within an area of 11.5 square miles, and located 12 miles southeast of the City of Los Angeles, jointed the rapidly swelling ranks of California cities to become the 50th incorporated city in Los Angeles County. By an overwhelming mandate, the citizens of Downey voted for a Council-Manager form of government to run their community – the largest in population ever known to have incorporated in the United States. At that time, Downey had an assessed value of about $100,000,000 and consisted of some of the finest new homes in Southeastern Los Angeles County and 110 industrial firms, employing over 21,000 persons on a $75,713,000 budget. (City of Downey n.d.)
Downey YMCA
The Young Men’s Christian Association (YMCA), at times referred to as the Y, was founded in London on June 6, 1844, by George Williams:
George Williams, born on a farm in 1821, came to London 20 years later as a sales assistant in a draper’s shop, a forerunner of today's department store. He and a group of fellow drapers organized the first YMCA to substitute Bible study and prayer for life on the streets. By 1851 there were 24 Ys in Great Britain, with a combined membership of 2,700. That same year the Y arrived in North America:
It was established in Montreal on November 25, and in Boston on December 29. (Marshfield Clinic Health System YMCA 2024)
The YMCA grew throughout the country during the late nineteenth century and early twentieth century. During the late 1930s, Harold Wagner, a YMCA executive for the Los Angeles area, approached Hubert Noble, a college instructor and pastor of the First Presbyterian Church of Downey, about the possibilities of opening a facility within the city of Downey. Noble opened the basement of the church to serve as the first YMCA location in Downey (Brown 2011).
With just two small basement rooms at its disposal, the Downey YMCA, first incorporated as an extension of the Y branch in Huntington Park, began establishing clubs for grade school boys around town.
By April 29, 1941, plans for a permanent facility were initiated after a group of 29 men and women met in the church basement to discuss the future of the Y in Downey. Their expansion plan estimated that a Downey branch would cost nearly $5000 a year to operate, but nonetheless, the founding members, many of whom were parents, banded together and began the development process.

The Y’s first office was in the old Downey Paint Center. Later, the small office was moved to the second floor of the Masonic Temple at Third Street and Downey Avenue. By 1947, the new board members had acquired a make-shift office and club room building on the corner of Second and Myrtle streets purchased from Downey’s first mayor, James L. Stamps. (Brown 2011)
City directories indicate that the Mrytle location was located at 11016 Myrtle Street, situated just under one-half mile north of the current location of 11531 Downey Avenue. Although Pierce describes the location as “a make-shift office and club room building,” newspaper accounts from 1964 indicate the building originally served as a Navy mess hall during World War II (Press Telegram 1964).
In 1955, the organization acquired the 11531 Downey Avenue property. Based on a Chain of Title (COT) inquiry, the property was originally three parcels, with one parcel being acquired from William Ward Altig and Marie Shelter Altig, and the remaining two parcels acquired from John W. Ezzell and Florence V. Ezzell. No records could be found to indicate whether the Ezzell’s actually resided within the property. Conversely, the Altigs did live at the property, and it is evident the property was the most notable of those acquired. William Altig was a doctor and had a large three-story colonial home with a tennis court, horse stables, swimming pool, and other amenities. The property “was considered the showplace of Downey homes at that time” (Brown 2011). The YMCA purchased Altig’s property for $67,000 in August of 1955 (Brown 2011).
Soon after the purchase, the Y moved its offices from Second and Myrtle to the Altig mansion, which underwent some minor alterations in order to provide meeting rooms for the expanding Y clubs. Following the transition, Stamps donated the old YMCA property to the Arc of Southeast Los Angeles County to help establish its first office in 1956. (Brown 2011)
Demand for more space at the new YMCA led to a campaign to raise funds for an expansion of the facility in 1962. In 1963, the architectural firm of Roy Donley & Associates were contracted to design a new facility estimated to cost $371,000 (Press Telegram 1964). Ultimately, the new 20,000-square foot YMCA facility, constructed next to the Altig residence, cost $432,000 and was dedicated in September of 1963 (Brown 2011).
The continued growth of the region during the mid-twentieth century led to a desire to expand the YMCA facility and a new fundraising campaign to raise 2.25 million dollars took place from the fall of 1973 through the spring of 1974 (Brown 2011). This expansion led to the demolition of the Altig residence in January of 1976 to expand the YMCA facility to the 44,000- square foot building now found at 11531 Downey Avenue

1.4 Results of the Archaeological Records Search
An archaeological records search for a one-mile radius around the project was conducted by BFSA at the SCCIC at CSU Fullerton. According to the records search results, eight resources (all historic) have been recorded within one mile of the project, one of which (P-19-190639) is recorded within the subject property. Site P-19-190639 is the YMCA recreational building at 11531 Downey Avenue. The building was recorded and evaluated by K.A. Crawford of Micha el Brandman Associates in 2013. Crawford concluded that the design, materials, and workmanship of the structure had been altered by a major addition to the northern portion of the building in the 1970s. Subsequently, Crawford evaluated the building as not eligible for the NRHP. Table 1.4– 1 provides descriptions for all resources identified during the SCCIC search.

The records search also identified 16 cultural resources studies which have previously been conducted within one mile of the project, one of which, conducted by Michael Brandman Associates, overlaps the subject property (Bonner et al. 2013). The 2013 study was conducted in support of the updating of cell phone signal towers located on top of the YMCA recreational building and included the formal recordation and evaluation of P-19-190639. The full records search results are included in Appendix C.
In addition, BFSA reviewed the following historic sources:

• 1923 Bell and 1964 South Gate (7.5-minute) USGS maps
• Aerial photographs (1928 through 2023)
The historic maps depict buildings within the project vicinity as early as 1899. Based on the aerial photographs (Plates 1.4–1 through 1.4–8), in 1928, the subject property and surrounding area consisted of rural residential and single-family agricultural properties. Although county assessors’ records show the 8268 Arnett Street residence was constructed in 1947, an aerial photograph from June 18, 1947, shows that at that time, the residence still had not been constructed. Regardless, by 1952, much of the surrounding area had been developed for residential and commercial use and the 8268 Arnett Street residence with detached garage is visible. The next available photograph, from 1963, shows the construction of the YMCA recreational building. At that time, the building footprint appears similar to the portion of the building which current plans indicate will remain intact and be retrofitted. However, it is likely the photograph was taken during the process of construction in 1963, as by 1968, the building is an “L”-shaped structure. The 1968 aerial also depicts the commercial/office building at 11525 Downey Avenue. Little change is evident on the 1976 aerial; however, in 1982, the large addition to the north of the YMCA recreational building, noted by Crawford, is visible. Subsequent photographs do not show any major changes noticeable at the scale of the imagery.
BFSA also requested a SLF search from the NAHC, which was negative for the presence of any recorded Native American sacred sites or locations of religious or ceremonial importance within one mile of the project. All correspondence is provided in Appendix D.

1.5 Applicable Regulations
Resource importance is assigned to districts, sites, buildings, structures, and objects that possess exceptional value or quality illustrating or interpreting the heritage of Los Angeles County in history, architecture, archaeology, engineering, and culture. A number of criteria are used in demonstrating resource importance. Specifically, the criteria outlined in CEQA, provide the guidance for making such a determination. The following sections detail the criteria that a resource must meet in order to be determined important.
1.5.1 California Environmental Quality Act
According to CEQA (§ 15064.5a), the term “historical resource” includes the following:
1) A resource listed in or determined to be eligible by the State Historical Resources Commission for listing in the CRHR (Public Resources Code [PRC] SS5024.1, Title 14 CCR. Section 4850 et seq.).
2) A resource included in a local register of historical resources, as defined in Section 5020.1(k) of the PRC or identified as significant in an historical resource survey, meeting the requirements of Section 5024.1(g) of the PRC, shall be presumed to be historically or culturally significant. Public agencies must treat any such resource as significant unless the preponderance of evidence demonstrates that it is not historically or culturally significant.
3) Any object, building, structure, site, area, place, record, or manuscript, which a lead agency determines to be historically significant or significant in the architectural, engineering, scientific, economic, agricultural, educational, social, political, military, or cultural annals of California may be considered to be an historical resource, provided the lead agency’s determination is supported by substantial evidence in light of the whole record. Generally, a resource shall be considered by the lead agency to be “historically significant” if the resource meets the criteria for listing on the CRHR (PRC SS5024.1, Title 14, Section 4852) including the following:
a) Is associated with events that have made a significant contribution to the broad patterns of California’s history and cultural heritage; b) Is associated with the lives of persons important in our past; c) Embodies the distinctive characteristics of a type, period, region, or method of construction, or represents the work of an important creative individual, or possesses high artistic values; or
d) Has yielded, or may be likely to yield, information important in prehistory or history.
Attachment I.D
Agenda Page 259
Cultural Resources Study for the YMCA Downey Project
1.0–24
4) The fact that a resource is not listed in, or determined eligible for listing in the CRHR, not included in a local register of historical resources (pursuant to Section 5020.1[k] of the PRC), or identified in an historical resources survey (meeting the criteria in Section 5024.1[g] of the PRC) does not preclude a lead agency from determining that the resource may be an historical resource as defined in PRC Section 5020.1(j) or 5024.1.
According to CEQA (§ 15064.5b), a project with an effect that may cause a substantial adverse change in the significance of an historical resource is a project that may have a significant effect on the environment. CEQA defines a substantial adverse change as:
1) Substantial adverse change in the significance of an historical resource means physical demolition, destruction, relocation, or alteration of the resource or its immediate surroundings such that the significance of an historical resource would be materially impaired.
2) The significance of an historical resource is materially impaired when a project:
a) Demolishes or materially alters in an adverse manner those physical characteristics of an historical resource that convey its historical significance and that justify its inclusion in, or eligibility for inclusion in the CRHR; or b) Demolishes or materially alters in an adverse manner those physical characteristics that account for its inclusion in a local register of historical resources pursuant to Section 5020.1(k) of the PRC or its identification in an historical resources survey meeting the requirements of Section 5024.1(g) of the PRC, unless the public agency reviewing the effects of the project establishes by a preponderance of evidence that the resource is not historically or culturally significant; or,
c) Demolishes or materially alters in an adverse manner those physical characteristics of an historical resource that convey its historical significance and that justify its eligibility for inclusion in the CRHR as determined by a lead agency for purposes of CEQA.
Section 15064.5(c) of CEQA applies to effects on archaeological sites and contains the following additional provisions regarding archaeological sites:
1) When a project will impact an archaeological site, a lead agency shall first determine whether the site is an historical resource, as defined in subsection (a). 2) If a lead agency determines that the archaeological site is an historical resource, it shall refer to the provisions of Section 21084.1 of the PRC, Section 15126.4 of the guidelines, and the limits contained in Section 21083.2 of the PRC do not apply.
Attachment I.D
Agenda Page 260
Cultural Resources Study for the YMCA Downey Project
1.0–25
3) If an archaeological site does not meet the criteria defined in subsection (a), but does meet the definition of a unique archaeological resource in Section 21083.2 of the PRC, the site shall be treated in accordance with the provisions of Section 21083.2. The time and cost limitations described in PRC Section 21083.2 (c-f) do not apply to surveys and site evaluation activities intended to determine whether the project location contains unique archaeological resources.
4) If an archaeological resource is neither a unique archaeological nor historical resource, the effects of the project on those resources shall not be considered a significant effect on the environment. It shall be sufficient that both the resource and the effect on it are noted in the Initial Study or Environmental Impact Report, if one is prepared to address impacts on other resources, but they need not be considered further in the CEQA process.
Section 15064.5(d) and (e) contain additional provisions regarding human remains.
Regarding Native American human remains, paragraph (d) states:
(d) When an Initial Study identifies the existence of, or the probable likelihood of, Native American human remains within the project, a lead agency shall work with the appropriate Native Americans as identified by the NAHC as provided in PRC SS5097.98. The applicant may develop an agreement for treating or disposing of, with appropriate dignity, the human remains and any items associated with Native American burials with the appropriate Native Americans as identified by the NAHC. Action implementing such an agreement is exempt from:

2.0 RESEARCH DESIGN
The primary goal of the research design is to attempt to understand the way in which humans have used the land and resources within the project through time, as well as to aid in the determination of resource significance. For the current project, the study area under investigation is southeastern Los Angeles County. The scope of work for the cultural resources study conducted for the YMCA Downey Project included the survey of a 2.16-acre study area and the assessment of the YMCA recreational building at 11531 Downey Avenue (built 1963), the commercial/office building at 11525 Downey Avenue (built 1965), and the single-family residence with a detached garage at 8268 Arnett Street (built between 1947 and 1950). Given the area involved, the research design for this project was focused upon realistic study options. Since the main objective of the investigation was to identify the presence of and potential impacts to cultural resources, the goal is not necessarily to answer wide-reaching theories regarding the development of early southern California, but to investigate the role and importance of the identified resources. Nevertheless, the assessment of the significance of a resource must take into consideration a variety of characteristics, as well as the ability of the resource to address regional research topics and issues.
Although survey programs are limited in terms of the amount of information available, several specific research questions were developed that could be used to guide the initial investigations of any observed cultural resources:
• Can located cultural resources be associated with a specific time period, population, or individual?
• Do the types of located cultural resources allow a site activity/function to be determined from a preliminary investigation? What are the site activities? What is the site function? What resources were exploited?
• How do the located sites compare to others reported from different surveys conducted in the area?
• How do the located sites fit existing models of settlement and subsistence for the region?
For the historic buildings, the research process was focused upon the built environment and those individuals associated with the ownership, design, and construction of the building.
Although historic structure evaluations are limited in terms of the amount of information available, several specific research questions were developed that could be used to guide the initial investigations of any observed historic resources:
• Can the building be associated with any significant individuals or events? • Is the building representative of a specific type, style, or method of construction? • Is the building associated with any nearby structures? Does the building, when studied with the nearby structures, qualify as a contributor to a potential historic district? Attachment I.D
Agenda Page 262

• Was the building designed or constructed by a significant architect, designer, builder, or contractor?
Data Needs
At the survey level, the principal research objective is a generalized investigation of changing settlement patterns in both the prehistoric and historic periods within the study area. The overall goal is to understand settlement and resource procurement patterns of the project area occupants. Further, the overall goal of the historic structure assessment is to understand the construction and use of the building within its associated historic context. Therefore, adequate information on site function, context, and chronology from both archaeological and historic perspectives is essential for the investigation. The fieldwork and archival research were undertaken with the following primary research goals in mind:
1) To identify cultural and historic resources occurring within the project; 2) To determine, if possible, site type and function, context of the deposit, and chronological placement of each cultural resource identified, and the type, style, and method of construction for any buildings;
3) To place each cultural resource identified within a regional perspective; 4) To identify persons or events associated with any buildings and their construction; and 5) To provide recommendations for the treatment of each cultural and historic resource identified.

3.0 ANALYSIS OF PROJECT EFFECTS
The cultural resources study of the project consisted of an institutional records search, archival research, an intensive cultural resource survey of the entire 2.16-acre study area, and the preparation of this technical report. This study was conducted in conformance with Section 21083.2 of the California Public Resources Code and CEQA. Statutory requirements of CEQA (Section 15064.5) were followed for the identification and evaluation of resources. Specific definitions for archaeological resource type(s) used in this report are those established by the State Historic Preservation Office (SHPO 1995).
3.1 Survey Methods
The survey methodology employed during the current investigation followed standard archaeological field procedures and was sufficient to accomplish a thorough assessment of the project. The field methodology employed for the project included walking evenly spaced survey transects set approximately 10 meters apart while visually inspecting the ground surface. All potentially sensitive areas where cultural resources might be located were closely inspected.
Photographs documenting survey areas and overall survey conditions were taken frequently.
3.2 Results of the Field Survey
BFSA staff archaeologist Mary Chitjian conducted the cultural resources survey of the YMCA Downey Project on April 15, 2024. The survey was an intensive reconnaissance consisting of a series of survey transects across the project. While the entire project was accessible, ground surface visibility was poor as the subject property is entirely developed containing the YMCA recreational building at 11531 Downey Avenue, a commercial/office building at 11525 Downey Avenue, and one single-family residence with a detached garage at 8268 Arnett Street, along with associated hardscape and landscaping (Plates 3.2–1 and 3.2–2). Vegetation within the property consisted entirely of maintained commercial and residential landscaping. The survey did not identify any prehistoric resources or archaeological sites within the property. However, all structures within the property are older than 50 years in age and must be evaluated for inclusion in the CRHR. The YMCA recreational building at 11531 Downey Avenue (built 1963) is already recorded as P-19-190639, while the commercial/office building at 11525 Downey Avenue (built 1965) and the single-family residence with a detached garage at 8268 Arnett Street (built between 1947 and 1950) have temporarily been recorded as Temp-1 and Temp-2, respectively (Figures
3.2‒1 and 3.2‒2). The appropriate State of California Department of Parks and Recreation (DPR) site record forms/updates for each resource were submitted to the SCCIC. Once processed, the SCCIC will assign permanent site number for sites Temp-1 and Temp-2. The following section provides the pertinent field results for the significance evaluation for sites P-19-190639, Temp-1, and Temp-2.

3.3 Historic Structure Analysis
Within the boundaries of the subject property, three historic properties were identified consisting of the single-family residence with a detached garage at 8268 Arnett Street (built between 1947 and 1950), the commercial/office building at 11525 Downey Avenue (built 1965), and the YMCA recreational building at 11531 Downey Avenue (built 1963). Descriptions and significance evaluations of the historic resources are provided below.
3.3.1 History of the Property: Ownership and Development The tracing of property ownership and development within the subject property focused on each individual property from the date of construction.
8268 Arnett Street (Temp-2)
The residential neighborhood surrounding 8268 Arnett Street was subdivided in 1945 as part of Tract Number 13240. However, 8268 Arnett Street and the other two properties that comprise the current study, 11531 and 11525 Downey Avenue, are depicted on the Tract Number 13240 tract map as “Not A Part of This Subdivision.” As such, it is not entirely clear when the parcels that comprise the property were subdivided. Regardless, County Assessors data indicates the residence at 8268 Arnett Street was constructed in 1947; however, the residence does not appear on a 1947 aerial of the property and a review of city directories did not identify a listing for the residence until 1950, when William Kimberly, his wife Doris, and son Fred, likely from a previous marriage, are listed at the home (Ancestry.com 2011). William is listed as a tin smith and Fred as a cabinetmaker. Minimal information could be found regarding the Kimberlys.
William was born in Toronto, Ontario, Canada in 1897, while Doris was born in Toronto in 1914.
They were not married until 1947, and in 1948, they moved to the United States (Ancestry.com 2014). The 1950 Federal Census lists the family at a different residence in Downey, 11832 Paramount Boulevard, indicating that when listed in the 1950 directory, the family had not been at the Arnett Street residence for long (Ancestry.com 2022).
A requested COT report failed to identify the original owner of the property or architect.
The City of Downey did not respond to requests for the original building permit. Further, limited information regarding individuals owning and/or residing at the property could be found through archival research. Based on a review of city directories available from Ancestry.com and newspaper entries found during property research, the individuals residing at the residence changed regularly between 1950 and 1975 (Table 3.3‒1). As such, it appears the residence served as a rental property and no information tying any of the individuals listed at the property to significant events could be found through archival research. Based on the COT for the property, the YMCA acquired the parcel from Ross P. Dunton as Executor of the Estate of Dorothy E.
Dunton in 1992.

11525 Downey Avenue (Temp-1)
County Assessors records indicate the commercial/office building at 11525 Downey Avenue was constructed in 1965. Archival research did not identify an architect for the building and the City of Downey did not respond to requests for the original building permit. According to city directories and the COT the first tenant and owner of the building was the Downey School Employees Federal Credit Union. The 1965 city directory lists both the Downey Education Association and the aforementioned credit union at the building. The Downey School Employees Federal Credit Union owned the building through 1975, when they constructed a new building at the northeast corner of Third and New streets (Los Angeles Times 1975a). Based on the COT for the property, that same year the building was sold to Kenton and Patricia Krogstad and Joel and Rita McCurdy, who rented out the office space of the building. By November of 1975, Brown & Associates Realtors is listed at the property (Los Angeles Times 1975b) and in 1978, RE/MAX Properties is listed (Los Angeles Times 1978). Other businesses identified at the property during Attachment I.D

the 1980s include the Van Buren Associates, A California Limited Partnership in 1985 (Press- Telegram 1985) and Robert Coates-C.P.A. in 1988 (Press-Telegram 1988). Based on the COT, the Krogstads and McCurdys held the property until it was sold to the YMCA in 1997. It appears the YMCA continued to rent the building as Google Street View images from 2014 and 2015 show signs at the building advertising the grand opening of the Bellflower Law Center.
11531 Downey Avenue (P-19-190639)
The history of the 11531 Downey Avenue property is presented within the historic context section (see Section 1.3). As outlined in the history of the Downey YMCA, the current 11531 Downey Avenue property was acquired in 1955. The YMCA initially utilized William Altig’s former residence and grounds for their offices and meeting spaces until a new facility, designed by Roy Donley & Associates, was constructed in 1963. In 1976, the Altig residence was demolished, and the YMCA building was expanded to the current building size now found at 11531 Downey Avenue (Brown 2011).
Roy Donley, the architect who designed the building, was born in Kenosha, Wisconsin on August 13, 1913 (PCAD 2024). Donley graduated from the University of California, Berkeley in 1938. The 1956 American Architects Directory list his principal works at that time as:
Hall of the Crucifixion-Forest Lawn Mem. Park, 51; Off. Bldg, L.A, E. I. du Pont de Nemours & Co; Kimberly Corp, Fountain Pen Factory, Culver City, Cal, & Synthetic Rubber Warehouse-Midland Rubber Corp, L.A, 53; Friden Calculators Office Building, Los Angeles, Calif, 55; Young’s Market Co, Liquor Warehouse, Long Beach, Calif. (American Architects Directory 1956)
Donely worked throughout the Los Angeles area during the 1950s and 1960s and designed modern institutional buildings exhibiting International, New Formalism, and Brutalism architectural styles. Some of Donley’s more well-known institutional buildings include the Charles Drew Middle School at 8511 Compton Avenue (Dudek 2022), the Verbum Dei High School at 11100 South Central Avenue (The Tidings 1963), as well as multiple schools in Torrance such as West High School, South High School, Hickory Elementary, and Towers Elementary (American Architects Directory 1970; Gnerre 2022).
After retirement from architecture, Donley became a successful watercolor artist and won several awards in addition to being an active member of the Pacific Palisades Art Association (Palisadian-Post 2008).
3.3.2 Description of Surveyed Resources
8268 Arnett Street
The 8268 Arnett Street single-family residence was constructed between 1947 and 1950 in the Minimal Traditional architectural style. The building exhibits a smooth, stucco finish and features a low-pitched hipped roof with a moderate eave overhang and composite shingles (Plates Attachment I.D
Agenda Page 270
Cultural Resources Study for the YMCA Downey Project
3.0–8
3.3–1 and 3.3–2). The roof plan is rectangular in shape (see Plate 1.4–8). On the primary (northeast) façade, the foundation of the residence is raised, with two concrete steps to access a covered concrete slab porch, the roof of which is supported by two painted 4" x 4" posts, one at the east corner of the porch and the other near the center of the porch (Plate 3.3–3). It is unknown whether the concrete slab continues to the interior or if the rest of the residence has a wood frame foundation.
A continuous concrete walkway starts at the street curb on Arnett Street with grass on both sides, is intersected by a concrete sidewalk, then continues straight, dividing the front yard lawn on either side, continuing to the two concrete steps on the northeast (primary) façade of the residence (see Plates 3.3–1 and 3.3–2). The steps connect to the covered concrete slab porch, which in turn leads to the main entrance of the residence. The main entrance features a white- painted, six-paneled wood door, which is near the center of the primary façade. It is unknown whether the wood door is original. The main entrance is located southeast of a protruding section of the residence, which features a 1/1 square vinyl-framed, single- or double-hung window. The main entrance is also southeast of a square 1/1 wood- or vinyl-framed, single- or double-hung window (two horizontal fixed panels per pane), which is flush with the door in a recessed wall, sitting under the covered porch (see Plate 3.3–3).
The main entrance is located northwest of a projected wall that forms three sides of a hexagon, with the segment facing the street being larger than the two flanking it. The northwest segment features a 1/1 vinyl- or wood-framed, single- or double-hung window (two horizontal fixed panels per pane). The central segment features a square picture window with four horizontal fixed panes. The southeast segment features a 1/1 vinyl-framed, single- or double- hung window (see Plate 3.3–3). The vinyl-framed windows replaced the original wood-framed windows present when the building was constructed.
The southeast façade of the residence features three 1/1 vinyl-framed, single- or double- hung windows (Plate 3.3–4). A vertical, stuccoed utility meter box protrudes from the building and is located between the southernmost window and the middle window. The roof line along the southeast façade of the residence features a small eave.
Along the perimeter of the southeastern property boundary, offset from the southeast façade, a red concrete block wall separates the residence from an adjacent parking lot, forming a setback of a few feet. It is unknown whether the wall belongs to the 8268 Arnett Street residence or to the adjacent property, the commercial/office building located at 11525 Downey Avenue (see Plates 3.3–1 and 3.3–4). The wall begins at the south corner of the property, extending northeast along the southeastern boundary, and then drops four blocks to a lower height for the last few feet.
The wall ends flush with the northeast façade of the 11525 Downey Avenue commercial/office building, a few feet before the sidewalk begins (see Plate 1.4–8).

The southwest façade of the residence was not accessible during the field survey and is not clearly visible in aerial imagery. It is unknown if it features doors or windows. It appears flush without projections or recessions. Southwest of the façade is the backyard which reaches the property boundary. It is unknown whether a physical separation such as a fence or wall exists with the adjacent outdoor corridor of the 11531 Downey Avenue property or if the 8268 Arnett Street residence is accessible via the 11531 Downey Avenue property (see Plate 1.4–8).
The northwest façade of the 8268 Arnett Street residence features two 1/1 vinyl- or wood- framed, single- or double-hung windows, one on each end of the façade, and a door with 1/1 top glazing in the middle of the façade. The roof line along the northwest façade of the residence features a small eave; however, the eave projects noticeably further over the door area (Plate 3.3– 5).
A detached garage is located in the west corner of the property and has a pyramid or hipped roof and a similarly colored smooth, stucco finish to the residence (see Plate 3.3–2). The roof plan of the garage is rectangular in shape (see Plate 1.4–8). A concrete slab the width of the garage door forms a continuous driveway from the street to the garage (see Plate 3.3–2). The northeast façade of the detached garage features a white, counterweight garage door with horizontal wood panels (Plate 3.3–6). It is unknown whether the detached garage features doors or windows on its other façades as those areas were not accessible during the survey of the property.
A chain-link fence beginning at the north corner of the residence crosses northwest over the concrete-slab driveway, featuring a swinging double gate to allow entry to the driveway, and ends at the northwestern boundary of the property. Where the chain-link fence ends, a vertical wood plank fence runs southwest along the northwestern boundary of the property separating the 8268 Arnett Street property from the adjacent property (see Plate 3.3–6). Parallel to the chain-link fence, at a lower height, a concrete block wall begins at the northwest façade of the residence and continues northwest until meeting the concrete slab driveway. The concrete block wall then continues southwest along the concrete slab driveway, containing a white-painted, metal, vertical- bar entry gate, until connecting to the primary (northeast) façade of the detached garage (see Plate
3.3–5).
11525 Downey Avenue
The 11525 Downey Avenue building is a Brutalist-style, two-story commercial/office building which features a flat roof with parapets and an asymmetrical “L”-shaped plan on a concrete slab foundation (see Plates 1.4–8 and 3.3–7). The building has a textured white stucco finish. Given the depth of the floor and roof plates, and that the stucco façade projects slightly from the concrete slab foundation, the building appears to be built using standard wood frame construction (see Plates 3.3–7 and 3.3–8).
The primary (southeast) façade of the building is split into three sections, occupying nearly the length of the property limits. The southernmost section is a white, stuccoed façade with two narrow, floor-to-ceiling, slightly recessed slit windows located in the southern third of the section (see Plate 3.3–7).

The middle section of the primary façade houses the building’s vertical circulation, shielded from the elements by the second-story floor plate and the roof plate. The middle section is open on the southeast side of the building which forms a courtyard on the first floor and a balcony on the second story. Flush with the stucco façade of the south and north sections, the middle section of the building is gated with a wrought metal fence that starts at the concrete slab level, proceeds vertically to wrap around the horizontal, slightly recessed second-story floor plate, and continues upwards to become a guardrail for the second-story balcony area. This guardrail is loosely wrapped in barbed wire. On the first floor, a wrought metal gate is flanked symmetrically by wrought metal bars and opens into the previously described vertical circulation area (Plate 3.3– 9). Almost immediately inside the gate, a concrete-stepped stairway with a black metal handrail on either side separates the building into two modules, with doors and windows present on both sides of the stairs on the first and second floors.
The northernmost section of the primary (southeast) façade is a white, stuccoed façade with three narrow, floor-to-ceiling, slightly recessed slit windows located in the northern third of the section (see Plate 3.3–7).
The northeast façade of the building occupies about a third of the property perimeter (Plates
3.3–10 and 3.3–11). The building features a rectangular footprint with a small northwestern projection on the southern end creating an “L”-shape. The northeast façade of the projection is roughly half the size of the main part of the northeast façade. The northeast façade of the northwestern projection features two narrow, slightly recessed slit windows on the second story and a garage door with horizontal panels on the first floor.
The northwest façade of the main portion of the building is about two-thirds of the building’s dimension. The northwest façade features a single, narrow, slightly recessed slit window on the second story and three pedestrian doors on the first floor. The two doors located on the northern most section of the northwest façade are wood. The door located in the middle section of the northwest façade is a wrought metal barred door, opposite the metal door on the middle section of the primary (southeast) façade, and provides entrance to the first-floor courtyard (Plate 3.3–11).
The southwest façade of the building is two stories and features textured white stucco (Plate
3.3–12). It is about half of the length of the property perimeter (see Plate 1.4–8).
To the west of the building is a parking lot with a red concrete block wall along its boundaries. The wall was previously described when discussing the 8268 Arnett Street property.
The wall begins at the west corner of the northwestern projection of the building, continuing northwest along the boundary of the property. At the west corner of the property, the wall extends northeast along the northwestern boundary of the property, and then drops four blocks to a lower height for the last few feet. The wall ends flush with the northeast façade of the 11525 Downey Avenue building, a few feet before the sidewalk begins. The wall then extends southeast until terminating at the entrance to the parking lot (see Plates 3.3–4 and 3.3–10).

11531 Downey Avenue
According to a historic architectural assessment of the property located at 11531 Downey Avenue conducted by Wayne Bonner and Kathleen Crawford for Michael Brandman Associates in 2013, “The subject property is a one- and two-story, irregular shaped, asymmetrical, Modern style, community center building located in a mixed residential and commercial neighborhood” (Bonner and Crawford 2013). BFSA concurs with the previous assessment in the classification of Modern style and adds the specification of the International style. Additionally, Bonner and Crawford’s report assessed the construction details and condition:
The 53,673 square foot building has a concrete foundation, stucco and brick exterior, and a multilevel flat roof. A flat roof projects from the main façade and is supported by square pillars. Large sections of brick wall covering alternate with large stucco-faced wall sections, creating a geometric effect on the various façades.
The entrances include glass and metal doors. Windows vary in size, shape and placement around the façades and include rectangular shaped, multlite, metal framed, fixed pane windows. The building is in good condition but has been altered by a major addition in the 1970s on the north side of the structure. (Bonner and Crawford 2013)
The primary (southeast) façade features the YMCA logo (Plate 3.3–13). This façade occupies more than half of the property perimeter. The remaining perimeter is bounded by a mixed tinted- and raw-colored concrete block wall with a vertical chain-link fence topped by three lines of barbed wire added after 2021 to the top of the concrete block wall for additional security. In front of the concrete block wall is a YMCA pole sign constructed at an unknown date (Plate 3.3– 14). Three main openings to the wall are present. Two primary vehicular entrances are in the southern parking lot area that are gated by a chain-link fence and feature double swing gates. The third opening is an area accessible by foot with a swing door in the chain-link fence that provides access along the southwest façade of the building, flanked by two almost equally sized fence sections.
Following the third opening, the chain-link fence terminates at the corner of a red brick wall that bounds the southwest and southeast façades of the building. The southernmost section of the primary (southeast) façade of the building comprises the red brick wall topped by barbed wire (Plate 3.3–15). The center section of the primary (southeast) façade still features the red brick wall, but it is overlapped by an offset stucco wall, with the stucco wall extending to the top of the second-story roof. The stucco wall features the YMCA logo on the south end (see Plates 3.3–13 and 3.3–15). At the terminus of the white stucco wall, the red brick wall continues for a few feet before transitioning to a metal fence with vertical bars. The fence features a double swing door entrance and is topped with barbed wire. Offset from the rest of the southeast façade, behind the metal fence, is the northernmost section of the primary (southeast) façade.

This northernmost section of the primary (southeast) façade is the late-1970s addition. The white stucco façade features two rows of horizontal windows: one row on the first floor and one row on the second floor. The windows are arranged three in each row, with each window being three-paned. The center of the first-floor row features a double glass door. The windows and doors on the first floor were boarded over during or after 2022 (Plates 3.3–16 and 3.3–17).
The northeast façade of the building consists of the late-1970s addition and features a smooth stucco wall painted white with seven tripartite ribbon windows that overlook the single- family residence at 8268 Arnett Street (see Plate 3.3–1). At the very top of the façade, a band of brown, corrugated metal deck siding creates a datum. This section protrudes from the rest of the façade. The westernmost section of the northeast façade is recessed by the width of stairs and the smooth stucco façade is partially painted white. An outdoor metal utility stairway connects the roof to the ground level (see Plate 3.3–6). At the top of the stairs is a small landing where a chain- link fence extends for a few feet northwest along the roof. The landing leads to a doorway in the corrugated metal deck siding datum. A 1/1 window sits under the staircase landing.
The northwest façades of both the original building and the late-1970s addition are two stories and do not feature any doors or windows (Plate 3.3–18). The façade of the northernmost portion of the building (the late-1970s addition) is concrete, while the façade of the southernmost portion of the building (the original building) is red brick.
The southwest façade of the building features a two-story red brick façade on the westernmost half and a single-story red brick façade on the easternmost half (Plate 3.3–19). The two-story portion of the façade features no door or window openings but exhibits four white pilaster-type posts alternating with the brick sections. The two-story portion features a flat roof without any coping or parapet (Plate 3.3–20). The single-story portion of the southwest façade features several door openings that have been boarded over. The roof of the single-story portion is flat with a wide overhang (see Plates 3.3–19 and 3.3–21). At the easternmost end of the southwest façade, a metal door is located between the building and a red brick wall topped with barbed wire. The red brick wall continues southeast and intersects the red brick wall that comprises the primary (southeast) façade of the building (see Plate 3.3–21).
3.3.3 Significance Evaluation
CEQA guidelines (Section 15064.5) address archaeological and historic resources, noting that physical changes that would demolish or materially alter in an adverse manner those characteristics that convey the historic significance of the resource and justify its listing on inventories of historic resources are typically considered significant impacts.
Because demolition of the buildings located at 8268 Arnett Street, 11525 Downey Avenue, and partial demolition of 11531 Downey Avenue would require approval from the City of Downey as part of the proposed project, CEQA eligibility criteria were used to evaluate the historic structures within the property as potentially significant historic buildings.

Integrity Evaluation
When evaluating a historic resource, integrity is the authenticity of the resource’s physical identity clearly indicated by the retention of characteristics that existed during its period of construction. It is important to note that integrity is not the same as condition. Integrity directly relates to the presence or absence of historic materials and character-defining features, while condition relates to the relative state of physical deterioration of the resource. In most instances, integrity is more relevant to the significance of a resource than condition; however, if a resource is in such poor condition that original materials and features may no longer be salvageable, then the resource’s integrity may be adversely impacted. For the 8268 Arnett Street, 11525 Downey Avenue, and 11531 Downey Avenue buildings, seven aspects of integrity were used for the evaluation, as recommended in the National Register Bulletin: How to Apply the National Register Criteria for Evaluation (Andrus and Shrimpton 2002):
1. Integrity of Location [refers to] the place where the historic property was constructed or the place where the historic event occurred (Andrus and Shrimpton 2002). Integrity of location was assessed by reviewing historical records and aerial photographs in order to determine if the buildings had always existed at their present locations or if they had been moved, rebuilt, or their footprints significantly altered. Historical research revealed that the buildings located at 8268 Arnett Street, 11525 Downey Avenue, and 11531 Downey Avenue were constructed in their current locations between 1947 and 1965. Therefore, the buildings retain integrity of location.
2. Integrity of Design [refers to] the combination of elements that create the form, plan, space, structure, and style of a property (Andrus and Shrimpton 2002). Integrity of design was assessed by evaluating the spatial arrangement of the buildings and any architectural features present.
a. 8268 Arnett Street: The single-family residence and detached garage were constructed in the Minimal Traditional style, between 1947 and 1950. The only known modifications that have occurred to the residence and detached garage since their construction were the replacement of the original wood windows in the residence. Although vinyl windows are not characteristic of the Minimal Traditional style, the modification does not negatively impact integrity of design to the point of no longer retaining character-defining features of the style. Therefore, the 8268 Arnett Street buildings do retain integrity of design.
b. 11525 Downey Avenue: The commercial/office building was originally constructed in 1965 in the Brutalist style. No known modifications have been made to the building since its initial construction. Therefore, the 11525 Downey Avenue building retains integrity of design.
Attachment I.D
Agenda Page 297
Cultural Resources Study for the YMCA Downey Project
3.0–35
c. 11531 Downey Avenue: The recreational facility was built in 1963 as an International-style building. A major addition was built onto the northwest side of the building in the late 1970s. Although the addition was also constructed in the International style, it altered the form, plan, or space of the building and introduced new design features, such as the stucco walls and large corrugated metal datum, which impacted the overall style of the building. Therefore, the 11531 Downey Avenue building does not retain integrity of design.
3. Integrity of Setting [refers to] the physical environment of a historic property. Setting includes elements such as topographic features, open space, viewshed, landscape, vegetation, and artificial features (Andrus and Shrimpton 2002). Integrity of setting was assessed by inspecting the elements of the property, which include topographic features, open space, views, landscape, vegetation, man-made features, and relationships between buildings and other features. The 8268 Arnett Street single- family residence and detached garage were constructed between 1947 and 1950 and were originally located in a residential neighborhood surrounded by other mostly small, residential buildings. Since its construction, the 11525 and 11531 Downey Avenue buildings were built abutting the 8268 Arnett Street property. Due to their construction, the 8268 Arnett Street property no longer retains the same open space, views, landscapes, or man-made features associated with its 1947 to 1950 construction.
Likewise, the late-1970s addition to the northeast façade of the 11531 Downey Avenue building negatively impacted integrity of setting for not only the 8268 Arnett Street property, but also the 11525 Downey Avenue property, as well as the original portion of the 11531 Downey Avenue building. The late-1970s addition dwarfs the other buildings and encroaches up to the property lines of 8268 Arnett Street and 11525 Downey Avenue. As a result, none of the buildings retain integrity of setting.
4. Integrity of Materials [refers to] the physical elements that were combined or deposited during a particular period of time and in a particular pattern or configuration to form a historic property (Andrus and Shrimpton 2002). Integrity of materials was assessed by determining the presence or absence of original building materials, as well as the possible introduction of materials that may have altered the architectural design of the buildings.
a. 8268 Arnett Street: The one-story, single-family residence and detached garage were constructed in the Minimal Traditional style, between 1947 and 1950. Since the construction of the residence, a majority, if not all, of the original wood fenestration has been replaced with vinyl windows . As these modifications resulted in the replacement of original materials with those associated with later periods, the residence at 8268 Arnett Street does not Attachment I.D
Agenda Page 298
Cultural Resources Study for the YMCA Downey Project
3.0–36
feature materials representative of a specific period of time and, therefore, no longer retains integrity of materials. The detached garage, however, has not undergone any known modifications and, therefore, does retain integrity of materials.
b. 11525 Downey Avenue: The two-story commercial/office building was originally constructed in 1965 in the Brutalist style. No known modifications have occurred since the building’s construction, and, therefore, the building does retain integrity of materials.
c. 11531 Downey Avenue: The YMCA recreation center was built in 1963. Since its construction, a large addition was built onto the northeast side of the building.
As the addition removed the northeast façade of the original building and the northwest façade of the original northeast wing, materials original to those façades, assumed to be primarily brick, were removed as well. Furthermore, new materials were introduced as part of the late-1970s addition including the corrugated metal deck siding datum, ribbon windows, and smooth stucco finishes. As a result, the building no longer retains integrity of materials.
5. Integrity of Workmanship [refers to] the physical evidence of the labor and skill of a particular culture or people during any given period in history (Andrus and Shrimpton 2002). Integrity of workmanship was assessed by evaluating the quality of the architectural features present in the buildings.
a. 8268 Arnett Street: The original workmanship demonstrated by the construction of the 8268 Arnett Street residence and detached garage is average.
Since its construction, the residence has undergone the replacement of the original wood fenestration with vinyl windows. As the wood-framed windows were one of the only features of the building that exhibited any sort of workmanship, the residence no longer retains integrity of workmanship. In addition, although no known modifications have been made to the detached garage, there are no known original features that convey the physical evidence of the labor or skill of a particular culture or people during any given period in history. Therefore, the detached garage never possessed integrity of workmanship.
b. 11525 Downey Avenue: The two-story commercial/office was originally constructed in 1965 in the Brutalist style. No known modifications have occurred since the building’s construction, however, there are no physical features on the building that convey the physical evidence of the labor or skill Attachment I.D
Agenda Page 299
Cultural Resources Study for the YMCA Downey Project
3.0–37
of a particular culture or people during any given period in history. Therefore, the 11525 Downey Avenue building never possessed integrity of workmanship.
c. 11531 Downey Avenue: The YMCA recreation center was built in 1963 in the International style. Since its construction, a large addition was built onto the northeast façade of the building. As the addition removed the northeast façade of the original building and northwest façade of the original northeast wing, materials original to those façades, assumed to be primarily brick, were removed as well. In addition, new materials were introduced as part of the late-1970s addition including the corrugated metal deck siding datum, ribbon windows, and smooth stucco finishes. Regardless of the modifications, the building never featured any elements that convey the physical evidence of the labor or skill of a particular culture or people during any given period in history. Therefore, the 11531 Downey Avenue building never possessed integrity of workmanship.
6. Integrity of Feeling [refers to] a property’s expression of the aesthetic or historic sense of a particular period of time (Andrus and Shrimpton 2002). Integrity of feeling was assessed by evaluating whether or not the resources’ features, in combination with their setting, conveyed a historic sense of the property during the period of construction.
As noted previously, the integrity of the setting for the buildings has been lost due to the transformation of the surrounding properties. In addition, the loss of integrity of materials through the late-1970s addition to the 11531 Downey Avenue property and the replacement of windows on the 8286 Arnett Street single-family residence have impacted their ability to express an aesthetic or historic sense of a particular period of time. Although the 11525 Downey Avenue building has not undergone any known modifications to its materials the loss of setting has negatively impacted its integrity of feeling. As such, none of the buildings retain integrity of feeling.
7. Integrity of Association [refers to] the direct link between an important historic event or person and a historic property (Andrus and Shrimpton 2002). Integrity of association was assessed by evaluating the resources’ data or information and their ability to answer any research questions relevant to the history of the city of Downey or the state of California. The 8268 Arnett Street buildings were constructed between 1947 and 1950. Historical research did not reveal any connections to any important historic persons or events. Therefore, the buildings located at 8286 Arnett Street do not possess integrity of association. The 11525 Downey Avenue office/commercial building was constructed in 1965. Historical research did not reveal any connections to any important historic persons or events. Therefore, the 11525 Downey Avenue building does not possess integrity of association. The 11531 Downey Avenue YMCA recreation building was constructed in 1963 and underwent modifications in the late Attachment I.D
Agenda Page 300
Cultural Resources Study for the YMCA Downey Project
3.0–38
1970s. Historical research did not reveal any connections to any important historic persons or events. Therefore, the 11531 Downey Avenue building does not possess integrity of association.
Of the seven aspects of integrity, the 8268 Arnett Street residence and detached garage possess integrity of location and design, and the detached garage possesses integrity of location, design and materials. The 11525 Downey Avenue office/commercial building possesses integrity of location, design, and materials. The 11531 Downey Avenue YMCA recreation building possesses only integrity of location.
CRHR Evaluation
For a historic resource to be eligible for listing on the CRHR, the resource must be found significant at the local, state, or national level, under one or more of the following criteria:
• CRHR Criterion 1:
It is associated with events that have made a significant contribution to the broad patterns of California’s history and cultural heritage.
a. 8268 Arnett Street: The history of 8268 Arnett Street is tied to use as a single- family residence built sometime between the years 1947 and 1950. Historical research did not reveal any association with events that have made a significant contribution to the broad patterns of California’s history or cultural heritage.
Therefore, it does not qualify for CRHR Criterion 1.
b. 11525 Downey Avenue: The 11525 Downey Avenue commercial/office building was built in 1965. Historical research did not reveal any association with events that have made a significant contribution to the broad patterns of California’s history or cultural heritage. Therefore, it does not qualify for CRHR Criterion 1.
c. 11531 Downey Avenue: The 11531 Downey Avenue building is an recreational building built in 1963. Historical research did not reveal any association with events that have made a significant contribution to the broad patterns of California’s history or cultural heritage. Therefore, it does not qualify for CRHR Criterion 1.
• CRHR Criterion 2:
It is associated with the lives of persons important in our past.
Attachment I.D
Agenda Page 301
Cultural Resources Study for the YMCA Downey Project
3.0–39
Historical research revealed that neither 8268 Arnett Street, 11525 Downey Avenue, nor 11531 Downey Avenue are associated with any persons important in our past.
Because the properties could not be associated with the lives of any important persons in our past, the buildings are not eligible for designation under CRHR Criterion 2.
• CRHR Criterion 3:
It embodies the distinctive characteristics of a type, period, region, or method of construction; represents the work of an important creative individual; or possesses high artistic values.
a. 8268 Arnett Street: The 8268 Arnett Street building was constructed between 1947 and 1950 as a Minimal Traditional-style, single-family residence.
According to McAlester (2015):
Minimal Traditional homes can be found throughout the United States. During the early 1940s, concentrations were rapidly built where new sites for World War II production plants created an urgent local need for worker housing. After the war, developers built instant communities – such as Levittown, New York on Long Island, and Brentwood in Denver, Colorado – filled with Minimal Traditional houses, sometimes using only a few
designs in a subdivision. These were sometimes located outside the city’s built-up edge, where large tracts of land were available and new broad highways and arterials were planned for easy automobile access.
The Minimal Traditional house was “the little house that could.” It was the small house that could be built with FHA [Federal Housing Administration]-insured loans in the midst of the Great Depression between 1935 and 1940; the house that could be built quickly to accommodate millions of relocating World War II production-plant workers (1941-1945); and the house that could be built rapidly during the late 1940s in large post-World War II developments (1946-1949) …
Identifying features of the Minimal Traditional style include:
Low- or intermediate-pitched roof, more often gabled; small house, generally one-story in height; roof eaves have little or no overhang; double-hung windows, typically multi-pane or 1/1; Attachment I.D

minimal amounts of added architectural detail; rarely has dormers. (McAlester 2015)
The 8268 Arnett Street residence features seven characteristics of the Minimal Traditional style, including:
The building was constructed between 1947 and 1950, within the Minimal Traditional style’s height of popularity, which lasted from circa 1935 to 1950 (McAlester 2015). Within the Minimal Traditional style, McAlester (2015) has identified three principal subtypes: Gable-and-Wing Roof, Side-Gabled Roof (commonly called Cape Cod), and Other Roof. The 8268 Arnett Street residence is classified as the Other Roof subtype, since it does not feature any gables. McAlester (2015) also notes that while “hipped-roof and front-gabled [Minimal Traditional] houses are found, with hipped-roof versions the more widespread … these variations appear to be less common than other subtypes.” As such, the 8268 Arnett Street residence is most representative of a hipped- roof Minimal Traditional style residence.
The only known modification to the residence is the replacement ofwindows from wood frame to vinyl. It is unknown if the front door is original. While these alterations do not negatively impact the integrity of design for the building, the residence no longer retains integrity of materials, setting or feeling, and it never possessed integrity of workmanship or association. As such, although the residence features character-defining features of the Minimal Traditional style, due to an overall lack of integrity, it does not embody distinctive characteristics of a type, period, region, or method of construction.
Therefore, as the residence is not considered architecturally significant, was not constructed using indigenous materials, and is not a valuable example of the use of indigenous materials or craftsmanship, it is not eligible for designation under CRHR Criterion 3.
b. 11525 Downey Avenue: According to the Modernism Context Statement (City of San Diego 2007), the Brutalism style originated from the French term béton brut, meaning “raw concrete.” Worldwide, buildings designed in the Brutalism style began to be built as early as the 1950s. Largely inspired by Le Corbusier, a Swiss architect, buildings designed in the Brutalism style are strikingly blockish, geometric, and contain design elements with repetitive shapes. The primary material used in construction of Brutalism-style buildings is concrete, which serves as not only the primary structural material, but also the finish.
Those critical of the style state that Brutalism buildings disregard the social Attachment I.D

environment, thereby causing the structure to seem inhuman, stark, and out of place.
According to the Modernism Context Statement, there are four “Primary” character-defining features of Brutalism construction (City of San Diego 2007).
The following Primary character-defining features noted in the Modernism Context Statement have been specifically applied to the 11525 Downey Avenue office/commercial building, accordingly:
1. Exposed and expressive structural system
The building has a defined second floor and roof plate in the middle section of the southeast façade. While 11525 Downey Avenue has a defined second floor and roof plates to show the vertical circulation, which can be considered expressive, they feature two finishes: stucco (second-floor plate) and parapet textured segmental paneling. As the structural system is not exposed, 11525 Downey Avenue does not possess this Primary character-defining feature of Brutalism construction.
2. Monumental massing
11525 Downey Avenue is large (at two stories) but does not fit the definition of “monumental.” The building is shorter than 11531 Downey Avenue’s tallest point. The 11525 Downey Avenue building, therefore, does not possess this Primary character-defining feature of Brutalism construction.
3. Angular and rectilinear forms
The 11525 Downey Avenue building consists of an L-shaped orthogonal massing, with rectilinear vertical designs present on the southeast, northeast, and northwest façades (narrow slit windows). Therefore, the 11525 Downey Avenue building does possess this Primary character-defining feature of Brutalism construction.
4. Exposed concrete as building finish
11525 Downey Avenue has exterior finishing such as stucco and parapet paneling. 11525 Downey Avenue, therefore, does not possess this Primary character-defining feature of Brutalism construction.
Attachment I.D
Agenda Page 304

3.0–42
Summary: Of the four Primary character-defining features of Brutalism construction expressed in the Modernism Context Statement, 11525 Downey Avenue possesses one feature.
According to the Modernism Context Statement, there are two “Secondary” character-defining features of Brutalism construction (City of San Diego 2007).
The following Secondary character-defining features noted in the Modernism Context Statement have been specifically applied to the 11525 Downey Avenue building, accordingly:
1. Repetitive patterns
The 11525 Downey Avenue building exhibits equally spaced, narrow, vertical slit windows on three façades of the building, which are a repetitive alteration of wall space, then window, then wall space. On the primary (southeast) façade, two slit windows at the southern end and three slit windows at the northern end span almost the height of the building. Likewise, on the northeast façade, three vertical windows are located towards the northernmost portion of the main section. The northwestern projection on the southern end of the building also features two narrow, vertical slit windows which only occupy the top half of the northeast façade. On the northwest façade of the main section of the building, only one window appears at the same height as the western projection.
The southwest façade has no slits or patterns of any kind; the wall only exhibits textured stucco. Despite the repetition seen in the vertical slit windows, the “repetitive patterns” feature refers more specifically to the structural form of the building and not the placement of windows or decorative elements. A definition of the form from the Saylor Academy states that “brutalist buildings usually are formed with striking repetitive angular geometries, and, where concrete is used, often revealing the texture of the wooden forms used for the in-situ casting” (Saylor Academy 2011). This description is further discussed by the authors of Brutalism:Online, who state that “brutalist buildings are usually formed with repeated modular elements forming massing representing specific functional zones” (Brutalism:Online n.d.). Although 11525 Downey Avenue exhibits a repetition of massing, with the south module being nearly symmetrical to the north module, it does not exhibit repetition of structural form, so it does not possess this Secondary character-defining feature of Brutalism construction.
Attachment I.D
Agenda Page 305

3.0–43
2. Intentional avoidance of traditional elements or ornament
The 11525 Downey Avenue building was constructed with no traditional elements (i.e., windows or doors except at the vertical circulation lobby entrance) and no ornamentation other than the wrought metal gate, fence, and narrow vertical slit windows in the southeast, northeast, and northwest façades. 11525 Downey Avenue, therefore, does possess this secondary character- defining feature of the Brutalism style.
Summary: Of the two secondary character-defining features of Brutalism construction expressed in the Modernism Context Statement, the 11525 Downey Avenue building possesses one of these features.
In evaluating the potential significance and eligibility for the designation of modern institutional buildings, the Modernism Context Statement notes the following:
In most cases these massive buildings are associated with the work of a recognized master architect, and would be considered for designation individually. Given the importance of the building form and materials to the expression of Brutalism, modifications which significantly alter or obscure these character-defining features may render the building ineligible for designation. (City of San Diego 2007)
The two-story commercial/office building at 11525 Downey Avenue was designed by an unknown architect and builder. In addition, because the building does not feature a majority of the primary character-defining features of the Brutalism style, 11525 Downey Avenue does not meet this evaluation criterion under the Modernism Context Statement. The Modernism Context Statement further notes:
Landscape styles vary dramatically for this sub-style. Location and setting are particularly relevant for Brutalist resources which are institutional and related to a ‘campus’ environment, and the preservation of the surrounding site may be important to the overall significance of the resource. (City of San Diego 2007)
The 11525 Downey Avenue building is not institutional in nature, and it is not part of a “campus” environment. The form and massing of 11525 Downey Attachment I.D
Agenda Page 306

Avenue do not “support a campus civic structure, giving architectural definition to the campuses’ streets, quadrangles, and other open spaces,” since the property does not possess streets, quadrangles, or other open spaces other than the parking lot. In addition, the varied building façades do not articulate “into constituent parts to mediate between the pedestrian scale and the scale of the building” to “provide visual continuity with neighboring buildings, and engage the landscape design of open spaces,” primarily because the property does not possess a pedestrian element or landscape design (UTSA Campus Master Plan 2014). Therefore, 11525 Downey Avenue does not meet this evaluation criterion for designation under the Modernism Context Statement. The Modernism Context Statement further notes, Southern California “examples of Brutalist architecture include some prominent structures such as Qualcomm Stadium and the Salk Institute, as well as a large concentration of downtown high-rises and buildings on the Campus of UCSD.”
11525 Downey Avenue is not a prominent structure, nor is it a high-rise located downtown or located in a campus environment. Therefore, 11525 Downey Avenue does not meet this evaluation criteria for designation under the Modernism Context Statement.
In summary, 11525 Downey Avenue only possesses one of the four primary character-defining features and one of the two secondary character-defining features of Brutalism construction, and therefore, cannot be considered a true, significant, representative example of Brutalism under the Modernism Context Statement.
c. 11531 Downey Avenue: In October 2007, the City of San Diego developed and implemented the Modernism Context Statement. The stated purpose of the Modernism Context Statement is to “assist in the identification, evaluation and preservation of significant historic buildings, districts, sites, and structures associated with the Modernism movement in San Diego from 1935 to 1970” and was created to better understand “Modern era resources and the types of resources that are significant to the history and development of San Diego” (City of San Diego 2007). The California SHPO utilizes the Modernism Context Statement in conjunction with the evaluation of potential historic resources constructed within the Modern era from 1935 to 1970.
According to Bonner and Crawford’s 2013 report and the Modernism Context Statement, the YMCA Complex at 11531 Downey Avenue was designed and constructed as a Modern style building in 1963. More specifically, the building Attachment I.D
Agenda Page 307

features International style elements. However, the building was constructed after the circa 1935 to 1955 period of significance for International structures defined by the Modernism Context Statement (City of San Diego 2007), but within the circa 1925 to present period of significance provided by McAlester (2015).
According to the Modernism Context Statement, the International style was a major worldwide architectural trend of the 1920s and 1930s that reflects the formative decades of Modernism prior to World War II (City of San Diego 2007). Although the International style originated in western Europe, it transcended any national or regional identity because International-style architecture made no reference to local vernaculars or traditional building forms. The style quickly migrated to the United States as architects from Europe fled prior to World War II. In Los Angeles, immigrant architects Rudolph Schindler and Richard Neutra were instrumental in popularizing the International style. The International style is characterized by a radical simplification of form and a complete rejection of ornament. Common features of International-style architecture include square and rectangular footprints, simple cubic or extruded rectangular forms, horizontal bands of windows, and strong right angles. Prominent building materials include concrete, smooth stucco, brick, and glass.
According to the Modernism Context Statement, there are four “Primary” character-defining features of International construction. The following primary character-defining features noted in the Modernism Context Statement (City of San Diego 2007) have been specifically applied to the 11531 Downey Avenue building:
1. Flat roofs (cantilevered slabs or parapets)
The 11531 Downey Avenue building has flat roofs throughout the various sections. Its southwest façade features a single-story portion that is flat with a wide overhang while other sections feature flat roof sections with parapets.
Therefore, the building does possess this primary character-defining feature of International construction.
2. Lack of applied ornament
The 11531 Downey Avenue building features a corrugated metal siding datum at the tallest level, located atop a portion of the late-1970s addition. As this is Attachment I.D
Agenda Page 308
Cultural Resources Study for the YMCA Downey Project
3.0–46
a decorative feature and not purely for function, the building features applied ornament. Therefore, the building does not possess this Primary character- defining feature of International construction.
3. Horizontal bands of flush windows
The 11531 Downey Avenue building features horizontal bands of flush windows along portions of the southeast and northeast façades. As these are part of the late-1970s addition and not original to the building, the original building does not possess this Primary character-defining feature of International construction. Although the addition possesses this character- defining feature, it is not a stand-alone structure and is not considered significant in its own right.
4. Asymmetrical façades
All façades of the 11531 Downey Avenue building are asymmetrical, compared to themselves and each other. Therefore, the building does possess this Primary character-defining feature of International construction.
Summary: Of the four Primary character-defining features of International construction expressed in the Modernism Context Statement, the 11531 Downey Avenue building possesses three features.
According to the Modernism Context Statement, there are four “Secondary” character-defining features of International construction. The following Secondary character-defining features noted in the Modernism Context Statement (City of San Diego 2007) have been specifically applied to the 11531 Downey Avenue building:
1. Square corners
The 11531 Downey Avenue building features square corners. Therefore, the building does possess this Secondary character-defining feature of International construction.

Agenda Page 309
Cultural Resources Study for the YMCA Downey Project
3.0–47
2. Common exterior materials include concrete, brick, and stucco
The 11531 Downey Avenue building features concrete, red brick, and smooth stucco exterior walls. Therefore, the building does possess this Secondary character-defining feature of International construction.
3. Steel sash windows (typically casement)
The 11531 Downey Avenue building features steel sash, fixed-pane windows; however, none are casement. Therefore, the building does not possess this Secondary character-defining feature of International construction.
4. Corner windows
The 11531 Downey Avenue building does not feature any corner windows.
Each corner of the buildings consists of a wall terminus. Therefore, the building does not possess this Secondary character-defining feature of International construction.
Summary: Of the four Secondary character-defining features of International construction expressed in the Modernism Context Statement, the 11531 Downey Avenue building possesses two features.
In evaluating the potential significance and eligibility for the designation of International buildings, the Modernism Context Statement notes the following:
International-style buildings were generally built for commercial or institutional use. The 11531 Downey Avenue building was constructed as a recreation center and has been used as such since its 1963 construction.
Therefore, the building does not meet this evaluation criterion under the Modernism Context Statement.
The Modernism Context Statement further notes that “Location and setting are particularly relevant for International style resources which are institutional and related to a ‘campus’ environment, and the preservation of the surrounding site may be important to the overall significance of the resource” (City of San Diego 2007). 11531 Downey Avenue is not institutional in nature and is not considered part of a “campus” environment. The form and massing of the building does not “support[s] a campus civic structure, giving architectural definition to the campuses’ streets, quadrangles, and other open spaces” (UTSA Attachment I.D
Agenda Page 310
Cultural Resources Study for the YMCA Downey Project
3.0–48
Campus Master Plan 2014). In addition, the building façades also do not articulate “into constituent parts to mediate between the pedestrian scale and the scale of the building … [to] engage the landscape design of open spaces” (UTSA Campus Master Plan 2014). Therefore, the property also does not meet this evaluation criterion for designation under the Modernism Context Statement.
In summary, the 11531 Downey Avenue building possesses three out of four of the Primary character-defining features and two out of four of the Secondary character-defining features identified in the Modernism Context Statement (City of San Diego 2007) to be considered a true, significant, representative example of an International-style structure. The building does not meet the evaluation criteria in the Modernism Context Statement regarding the types of buildings generally designed in the International style in Southern California (institutional) and their campus-like settings (City of San Diego 2007) and does not possess a high degree of original integrity. As a result the building is not eligible for designation under CRHR Criterion 3.
• CRHR Criterion 4:
It has yielded, or may be likely to yield, information important in prehistory or history.
The research conducted for this study revealed that neither the 8268 Arnett Street, nor the 11525 and 11531 Downey Avenue properties are likely to yield any additional information about the history of the city of Downey or the state of California.
Therefore, none of the properties are eligible for designation under CRHR Criterion 4.
Findings and Conclusions
The 8268 Arnett Street and 11525 and 11531 Downey Avenue buildings are evaluated as not eligible for the CRHR. The residence and detached garage at 8268 Arnett Street, the commercial/office building at 11525 Downey Avenue, and the recreational building at 11531 Downey Avenue cannot be tied to the historic development of the neighborhood. Further, none of the properties are associated with significant individuals, significant architectural examples, nor are they able to provide more information with regards to the history of the city of Downey.
Because the buildings located at 8268 Arnett Street and 11525 and 11531 Downey Avenue are not eligible for listing on the CRHR, no site-specific mitigation measures are required for any future alterations or planned demolition of the buildings.
3.4 Discussion/Summary
The field survey identified one Minimal Traditional-style residence and detached garage, one Brutalist-style commercial/office building, and one International-style recreational building.

No other cultural resources were observed during the survey. The 8268 Arnett Street and 11525 and 11531 Downey Avenue buildings meet the age threshold to require historic structure evaluations to determine eligibility for the CRHR ; however, the buildings do not possess a high degree of integrity and are evaluated as not historically or architecturally significant under any CEQA criteria.

4.0 INTERPRETATION OF RESOURCE IMPORTANCE AND IMPACT
IDENTIFICATION
4.1 Resource Importance
The cultural resources survey of the YMCA Downey Project identified the 1963 YMCA recreational building at 11531 Downey Avenue (P-19-190639), the 1965 commercial/office building at 11525 Downey Avenue (Temp-1), and the 1947 single-family residence with a detached garage at 8268 Arnett Street (Temp-2). No other cultural resources were observed during the survey. The 11531 and 11525 Downey Avenue and 8268 Arnett Street buildings meet the age threshold to require historic structure evaluations to determine eligibility for the CRHR. The conclusion of the current assessment is that the buildings and structures are not CEQA-significant or eligible for listing on the CRHR. The buildings have been thoroughly recorded and no additional information can be derived from further analysis.
4.2 Impact Identification
The proposed development of the YMCA Downey Project will include the demolition of the buildings at 11525 Downey Avenue and 8268 Arnett Street as well as the partial demolition of the YMCA recreational building at 11531 Downey Avenue. However, the removal of these buildings as part of the development of the property will not constitute an adverse impact because the buildings have been evaluated as not CEQA-significant and not eligible for listing on the CRHR. The potential does still exist, however, that historic deposits may be present that are related to the use of this location since the 1920s. To mitigate potential impacts to unrecorded historic features or deposits, monitoring of grading by an archaeologist is recommended. The monitoring program is presented in Section 5.0.
Attachment I.D
Agenda Page 313
Cultural Resources Study for the YMCA Downey Project
5.0–1
5.0 RECOMMENDATIONS
The proposed development will impact the buildings at 11531 Downey Avnue (P-19- 190639), 11525 Downey Avenue (Temp-1), and 8268 Arnett Street (Temp-2); however, as these resources are evaluated as not CRHR-eligible, impacts have been determined to be not significant.
Based upon the evaluation of the buildings and structures as lacking further research potential, resource-specific mitigation measures will not be required as a condition of approval for the project. However, the property and surrounding area have contained structures since as early as 1928, cleared for the construction of the current buildings during the early to mid-twentieth century. When land is cleared, disked, or otherwise disturbed, evidence of surface artifact scatters is typically lost. Whether or not cultural resources other than the evaluated buildings and structures have ever existed on the YMCA Downey Project property is unclear. As such, the current status of the property appears to have affected the potential to discover any surface scatters of artifacts, and cultural materials that may have been on-site could have been masked by both disking and prior grading across the property.
Given that the prior development within the project might have masked archaeological deposits, and based upon the limited visibility during the survey, there is a potential that buried archaeological deposits may be present within the project boundaries. The presence of commercial and residential buildings and structures within the subject property further indicates that there is a likelihood for the presence of associated historic deposits below the ground surface. Based upon this potential, monitoring of grading is recommended to prevent the inadvertent destruction of any potentially important cultural deposits that were not observed or detected during the current cultural resources study. The proposed monitoring tasks are detailed below.
During Grading
A. Monitor(s) Shall be Present During Grading/Excavation/Trenching
1. The archaeological monitor shall be present full-time during all soil-disturbing and grading/excavation/trenching activities that could result in impacts to archaeological resources.
2. The principal investigator (PI) may submit a detailed letter to the lead agency during construction requesting a modification to the monitoring program when a field condition such as modern disturbance post-dating the previous grading/trenching activities, presence of fossil formations, or when native soils are encountered that may reduce or increase the potential for resources to be present.
B. Discovery Notification Process
1. In the event of an archaeological discovery, either historic or prehistoric, the archaeological monitor shall direct the contractor to temporarily divert all soil - disturbing activities, including but not limited to, digging, trenching, excavating, or grading activities in the area of discovery and in the area reasonably suspected to Attachment I.D
Agenda Page 314
Cultural Resources Study for the YMCA Downey Project
5.0–2
overlay adjacent resources, and immediately notify the Native American monitor and client, as appropriate.
2. The monitor shall immediately notify the PI (unless the monitor is the PI) of the discovery.
C. Determination of Significance
1. The PI shall evaluate the significance of the resource. If human remains are involved, the protocol provided in Section D, below, shall be followed. a. The PI shall immediately notify the City of Downey to discuss the significance determination and shall also submit a letter indicating whether additional mitigation is required.
b. If the resource is significant, the PI shall submit an Archaeological Data Recovery Program (ADRP) and obtain written approval from City of Downey to implement that program. In the event that prehistoric deposits are discovered, the ADRP should also be reviewed by the Native American consultant/monitor. Impacts to significant resources must be mitigated before ground-disturbing activities in the area of discovery will be allowed to resume. c. If the resource is not significant, the PI shall submit a letter to the City of Downey indicating that artifacts will be collected, curated, and documented in the final monitoring report. The letter shall also indicate that that no further work is required.
D. Discovery of Human Remains
If human remains are discovered, work shall halt in that area until a determination can be made regarding the provenance of the human remains; and the following procedures as set forth in CEQA Section 15064.5(e), the California PRC (Section 5097.98), and the State Health and Safety Code (Section 7050.5) shall be undertaken:
1. Notification
a. The archaeological monitor shall notify the PI, if the monitor is not qualified as a PI.
b. The PI shall notify the Coroner’s Division of the Los Angeles County Sheriff’s Department after consultation with the City of Downey, either in person or via telephone.
2. Isolate discovery site
a. Work shall be directed away from the location of the discovery and any nearby area reasonably suspected to overlay adjacent human remains until a Attachment I.D
Agenda Page 315
Cultural Resources Study for the YMCA Downey Project
5.0–3
determination can be made by the sheriff-coroner in consultation with the PI concerning the provenance of the remains.
b. The sheriff-coroner, in consultation with the PI, will determine the need for a field examination to determine the provenance.
c. If a field examination is not warranted, the sheriff-coroner will determine, with input from the PI, if the remains are or are most likely to be of Native American origin.
3. If Human Remains ARE determined to be Native American
a. The medical examiner will notify the NAHC within 24 hours. By law, ONLY the medical examiner can make this call.
b. The NAHC will immediately identify the person or persons determined to be the most likely descendent (MLD) and provide contact information. c. The MLD will contact the PI within 24 hours or sooner after the sheriff-coroner has completed coordination to begin the consultation process in accordance with CEQA Section 15064.5(e), the California PRC, and the State Health and Safety Code.
d. The MLD will have 48 hours to make recommendations to the property owner or representative for the treatment or disposition with proper dignity of the human remains and associated grave goods.
e. Disposition of Native American human remains will be determined between the MLD and the PI, and, if:
i. The NAHC is unable to identify the MLD; OR
ii. The MLD failed to make a recommendation within 48 hours after being notified by the NAHC; OR
iii. The landowner or authorized representative rejects the recommendation of the MLD and mediation in accordance with PRC 5097.94 (k) by the NAHC fails to provide measures acceptable to the landowner; THEN iv. Upon the discovery of multiple Native American human remains during a ground-disturbing land development activity, the landowner may agree that additional conferral with descendants is necessary to consider culturally appropriate treatment of multiple Native American human remains.
Culturally appropriate treatment of such a discovery may be ascertained from review of the site utilizing cultural and archaeological standards.
Where the parties are unable to agree upon the appropriate treatment measures, the human remains and grave goods buried with the Native American human remains shall be reinterred with appropriate dignity.

5.0–4
4. If Human Remains are NOT Native American
a. The PI shall contact the sheriff-coroner and notify them of the historic-era context of the burial.
b. The sheriff-coroner will determine the appropriate course of action with the PI and county staff (PRC 5097.98).
c. If the remains are of historic origin, they shall be appropriately removed and conveyed to Los Angeles County. The decision for internment of the human remains shall be made in consultation with County, the applicant/landowner, and any known descendant group.
Post-Construction
A. Preparation and Submittal of Draft Monitoring Report
1. The PI shall submit to City of Downey a draft monitoring report (even if negative) prepared in accordance with the agency guidelines, which describes the results, analysis, and conclusions of all phases of the archaeological monitoring program (with appropriate graphics).
a. For significant archaeological resources encountered during monitoring, the ADRP shall be included in the draft monitoring report.
b. Recording sites with the State of California DPR shall be the responsibility of the PI, including the recording (on the appropriate forms-DPR 523 A/B) any significant or potentially significant resources encountered during the archaeological monitoring program.
2. The PI shall submit a revised draft monitoring report to the City of Downey for approval, including any changes or clarifications requested by the City.
B. Handling of Artifacts
1. The PI shall be responsible for ensuring that all cultural remains collected are cleaned and cataloged.
2. The PI shall be responsible for ensuring that all artifacts are analyzed to identify function and chronology as they relate to the history of the area; that faunal material is identified as to species; and that specialty studies are completed, as appropriate.
3. The cost for curation is the responsibility of the property owner.

YMCA DOWNEY TRIP GENERATION ASSESSMENT
Urban Crossroads, Inc. is pleased to provide the following Trip Generation Assessment for the YMCA Downey development (Project), located in the City of Downey. This trip generation assessment describes the proposed Project trip generation and determines whether any traffic operations analysis is required based on Los Angeles County’s Transportation Impact Analysis Guidelines (County Guidelines) dated July 23, 2020. Specifically, the purpose of the following trip generation assessment is to determine if any additional peak hour intersection operations analysis is required based on the County Guidelines. The County Guidelines have been utilized as the City does not have their own adopted guidelines.
PROPOSED PROJECT
The Project site is located at 11531 Downey Avenue which is northwest of Downey Avenue, south of Firestone Boulevard, and east of Paramount Boulevard (Assessor’s Parcel Numbers [APNs] 6255-013-032, -033, and -034). The site is currently developed with 3 structures totaling 61,756 square feet (3,254-square- foot building at 11525 Downey Avenue, 57,673-square-foot building at 11531 Downey Avenue, and 829-square-foot building at 8268 Arnett Street). The site was previously occupied by a YMCA which is currently not operational. The Project includes demolition of the existing structures on-site and developing an 18,808- square-foot gymnasium, 975-square-foot lobby/restrooms, and retrofitting of an approximate 7,625-square-foot existing gymnasium (total of 27,408 square feet).
A preliminary site plan for the proposed Project is shown in Exhibit 1. As indicated in Exhibit 1, access to the site will be accommodated via Downey Avenue and Arnett Street.
