Chan, AIA FROM: Casey Tibbet, M.A., Associate Cultural Resources Manager/Architectural Historian SUBJECT: Historic Resources Evaluation – Primary Record and Building, Structure, and Object (BSO) Form for 48 E. Colorado Boulevard in the City of Arcadia, Los Angeles County, California (LSA Project Number 20252289) LSA Associates, Inc. (LSA) completed a historical evaluation of the property at 48 E. Colorado Boulevard (Assessor Identification Number 5773-002-021) in the City of Arcadia. The property is developed with a single-family residence (1923) and a duplex (1950). LSA conducted research and an intensive-level field survey. The evaluation of the property was documented on Department of Parks and Recreation (DPR) 523A (Primary Record) and 523B (Building, Structure, and Object Record) forms and the property was identified on a DPR Location Map. As a result of LSA’s evaluation of this property, it was determined that the 1923 vernacular residence and the 1950 Ranch style duplex do not appear to be eligible for listing in the California Register of Historical Resources under any criteria or designation under the local ordinance. In summary, each residence is associated with a period of residential development that the City has identified as historically significant: Residential Development, 1910-1935 and Residential Development, 1946- 1970. The vernacular 1923 residence has been extensively altered (siding, fenestration, and an addition) and does not convey an association with the 1910-1935 period. The 1950 duplex has also sustained alterations (siding and additions) and is not a property type that on its own is representative of the 1946-1970 pattern of development. Research did not identify any historically significant people associated with the property. As previously stated, both buildings have sustained alterations. They are not good examples of any architectural styles, do not possess high artistic values, and are not iconic. For these reasons, the property at 48 E. Colorado Boulevard does not qualify as a “historical resource” as defined by the California Environmental Quality Act (CEQA) and, for purposes of this project, the City may make a finding of “no impact” regarding built environment historical resources.

Description: (Describe resource and its major elements. Include design, materials, condition, alterations, size, setting, and boundaries) This multi-family property is situated on the south side of E. Colorado Boulevard on a block that has commercial uses on three corners and a mix of modern and historic-period (50 years of age or older) multi-family residences. The property includes a single- family residence that was built in 1923, a detached one-car garage, and a duplex that was built in 1950. The Ranch style duplex is located at the front (north end) of the property. It has an approximately 20-foot-deep paved front setback and is separated from the sidewalk by an approximately four-foot-high wall and a metal gate. The one-story duplex is roughly rectangular in plan and rests on a raised foundation. It has a low-pitched, side-gable roof sheathed with composition shingles and no eaves. The exterior walls are clad with wood grain aluminum siding. Fenestration consists primarily of wood- framed double-hung windows with a few aluminum-framed sliding windows in the west elevation. The symmetrical, east-facing façade includes a covered, raised patio with a pair of windows and a door, two pairs of windows with metal awnings, and a covered patio with a door and a pair of windows. Both front patios have metal balustrades and metal posts that support the roofs over them. The south elevation has two windows with metal awnings, a wall-mounted air conditioner, and a vertical-rectangular attic vent. The north elevation has two windows with metal awnings, an air conditioning unit in one of the windows, a wall-mounted air conditioner, and a vertical-rectangular attic vent. The west elevation is barely visible but appears to include small additions at the north and south ends, some aluminum-framed and wood-framed windows, and at least one door. The duplex appears to be in fairly good condition but has sustained alterations including some aluminum-framed windows, window-mounted air conditioning units, and the aluminum siding.

Construction History: (Construction date, alterations, and date of alterations) No original building permits were found for the single-family residence. According to the Los Angeles County Office of the Assessor’s online property information system, the residence was built in 1923 (Los Angeles County Office of the Assessor n.d.). This is supported by Sanborn Fire Insurance Maps that show the residence at 46 Orange Avenue (now E. Colorado Boulevard) in February 1924 (Sanborn Fire Insurance Maps 1924). The following permits were found for the property (City of Arcadia var.): 1950 – Permit issued to owner William E. Hall to build duplex dwelling. Contractor is listed as B & H Construction Co. 1956 – Permit issued to owner H. E. Krol for a range. 1977 – Permit issued to owner Margaret S.

It is not a “historical resource” for the purposes of the California Environmental Quality Act (CEQA). Historic Context: Originally owned by the San Gabriel Mission and then a part of Rancho Santa Anita, the land that includes present-day Arcadia was also owned by Scottish immigrant Hugo Reid (Architectural Resources Group 2016). Reid was the first to make a modern impact on the land, raising cattle and building the first structure. After a succession of owners, in 1875 Elias J. “Lucky” Baldwin purchased 8,000 acres of the rancho along with much of the surrounding area (Ibid.). He established the Baldwin Ranch in the area that now contains the Los Angeles County Arboretum in what would become Arcadia (Ibid.). Residential development from 1875 to 1909 is one of the first important themes in the City’s history (Architectural Resources Group 2016). See Continuation Sheet B11.

Description (continued from page 1) The one-story, vernacular single-family residence is located at the rear (south end) of the property and is not visible from E. Colorado Boulevard. It is roughly rectangular in plan and appears to rest on a concrete slab. It has a very low-pitched, side-gable roof sheathed with composition shingles and has narrow eaves. The exterior walls are clad with wood grain aluminum siding. The north-facing façade has a louvered window, a door, a pair of wood-framed casement windows, and a wall-mounted air conditioning unit. The west elevation has a louvered window with a metal awning and a vinyl-framed window with an air conditioning unit in it. The south elevation (facing the alley) appears to be an addition and has two aluminum-framed sliding windows. The east elevation has a door, two aluminum-framed sliding windows, and a louvered window. The detached, one-car garage has a gable roof with exposed rafter tails, stuccoed walls, and a non-original door. The house appears to be in good condition, but has sustained alterations including the siding, windows, air conditioning units, and an addition. P5a.

Significance: (continued from page 2) In 1883, Baldwin subdivided 3,000 acres into the Santa Anita Tract (Architectural Resources Group 2016). The townsite included “town lots, villa sites, and larger 30-acre farm parcels (Architectural Resources Group 2016:27). Despite the construction of the Los Angeles & San Gabriel Valley Railroad (LA&SGVR) and one of its depots in the new townsite, sales were slow and “Baldwin deeded the remaining acreage of the Santa Anita Tract to his ranch manager Hiram Unruh” who had much greater success (Ibid.). By 1887, the townsite was known as Arcadia and the Atchison, Topeka & Santa Fe Railroad (ATSF) had gained control (see Continuation Sheet) DPR 523L (1/95) *Required Information State of California - The Resources Agency DEPARTMENT OF PARKS AND RECREATION CONTINUATION SHEET Primary # HRI # Trinomial Page 5 of 9 *Resource Name or #: (Assigned by recorder) 48 E. Colorado Boulevard *Recorded by LSA Associates, Inc. *Date: April 2025 X Continuation Update *B10. Significance: (continued from page 4) of the LA&SGVR, bringing more traffic through the area (Ibid.). The densest development occurred in the core of the town around the intersection of 1st Avenue and Santa Clara Street, where the ATSF and Southern Pacific railroads intersected (Architectural Resources Group 2016:33). The term “dense” is used loosely as the 1908 Sanborn maps show only one or two residences per block (Ibid.). Residential development in this part of town was on small lots, while development further south was on multi-acre parcels (Ibid.). As late as 1903, when a census was taken to ascertain the population of the proposed City of Arcadia, the area only had 642 residents, and many lived and worked on the Baldwin Ranch or were temporary residents working for the railroads (Ibid.). Regardless, with a booming economy increasingly based on entertainment, horse racing, hospitality, and gambling, Arcadia was incorporated in 1903, with Baldwin as its first mayor (Arcadia Historical Society 2021). Moving into the 1910s, Arcadia’s growth remained slow and steady (Architectural Resources Group 2016). However, the city began shifting away from “its sporting days to more respectable pursuits, as it outlawed liquor licensing in 1912 and embarked on a series of civic improvements” (Architectural Resources Group 2016:44). By 1915, electric streetlights had been installed in some areas and streets were graded and oiled (Ibid.). Residential development in the 1910s saw the subdivision of larger parcels into smaller ones (2.5 to 5 acres) that attracted a wider variety of buyers who were interested in a more suburban lifestyle with room for some agricultural pursuits (Architectural Resources Group 2016:49). Most of the 1910s subdivisions followed a grid pattern with graded and sometimes paved roads without curbs or sidewalks (Architectural Resources Group 2016). After World War I, the region thrived and the 1920s were a transformative period in Arcadia’s development (Ibid.). Residential subdivision accelerated with tracts designed in grid patterns like those of the 1910s, but with smaller lots (Architectural Resources Group 2016:36). Single-family residential construction dominated the period (Ibid.). Most of these were modest in size and the earliest were constructed in the Craftsman style, with Period Revival styles becoming dominant in the mid-1920s and into the 1930s (Ibid.). The smaller lot subdivisions were located closer to the original town center, Pacific Electric lines, and the commercial district at Huntington and First, while the larger multi-acre lots were in what was then the southern part of town (Ibid.). The 1929 to 1941 period was characterized nationally by massive unemployment and economic uncertainty, but Arcadia was one of the few places that did not experience a near cessation of construction (Architectural Resources Group 2016:65). The major factors for this were Anita Baldwin selling off the remaining approximately 1,300 acres of the Baldwin Ranch; establishment of military facilities and the related increase in demand for commercial businesses; and construction of a County park, which was a large Works Progress Administration (WPA) project (Ibid.). “In 1933, California re-legalized horse race betting, and Anita Baldwin seized her opportunity to revive her father’s racetrack dream” (Architectural Resources Group 2016:55). She sold 214 acres to a group of investors who hired Gordon Kaufman to design the grandstand, Turf Club, and clubhouse and landscape designer Tommy Tomson to design the park’s lush landscaping (Ibid.). “Santa Anita Park opened on Christmas day, 1934 and quickly became Arcadia’s signature landmark” (Ibid.). Other Baldwin acreage was parceled out into a number of residential subdivisions that jumpstarted construction between 1936 and 1941 (Ibid.). In Arcadia, multi-family development remained a very small component of the city’s housing stock during the Depression and World War II (WWII; Architectural Resources Group 2016). With the end of WWII and the return of thousands of veterans, Arcadia and the greater Los Angeles area saw an enormous explosion in the development of affordable housing. “For the first time in Arcadia, construction of multi-family housing helped to accommodate the large influx of new residents (Ibid.:86). Courtyard apartments were built along major thoroughfares like Baldwin Avenue, Santa Anita Avenue, and Huntington Drive (Ibid.). In the 1950s, one-story fourplexes and courtyard apartments were common, but in the 1960s two-story apartments and courtyard housing became more popular (Architectural Resources Group 2016). Residential construction in the 1960s was largely single- and multi-family infill housing in the Contemporary Ranch and Mid-Century Modern styles (Ibid.). Development during the 1945-1970 period transformed the city from semi- rural to suburban earning it the nickname a “Community of Homes” (Architectural Resources Group 2016:85). Residential Development, 1910-1935. The vernacular residence, which was built in 1923, is associated with the theme of Residential Development, 1910-1935 (Architectural Resources Group 2016). As briefly discussed above, residential construction increased in the pre- and post-World War I years. New subdivisions were typically laid out along a grid street pattern often without curbs or sidewalks. In the 1920s, single-family residential construction was dominated by modest sized Craftsman and Period Revival homes such as the subject residence. Residences associated with this theme are normally one or two stories, accompanied by a detached garage, and designed in the Craftsman, Tudor Revival, or Spanish Colonial Revival styles (Ibid.). To be historically significant, the residence must retain integrity, but because resources associated with this period are increasingly rare in Arcadia, “some latitude shall be applied when evaluating integrity” (Ibid.:52).

Colorado Boulevard *Recorded by LSA Associates, Inc. *Date: April 2025 X Continuation Update *B10. Significance: (continued from page 5) Postwar Residential Development, 1946-1970. The second residence was constructed in 1950 and, therefore, the property is also associated with the theme of Postwar Residential Development, 1946-1970. The post-WWII residential boom made a significant contribution to the broad patterns of local, regional, and even national history. In the 1960s, demographic and social changes led to major changes in the housing market (California Department of Transportation 2011). Young adults waited longer to get married and had children later. This, coupled with a rising divorce rate, created a demand for single-person households that translated into a demand for apartments (California Department of Transportation 2011). “The proportion of multi-family housing (apartments and condominiums) grew steadily in the 1960s, surpassing 40 percent of all new housing units constructed each year from 1968 through 1973. In California, the proportion of multi-family housing began to increase in the late 1950s and grew to become a majority of the new housing units built from 1962-64 and again from 1969-73” (California Department of Transportation 2011:53). The majority of the multi- family construction “took the form of low-rise garden apartment complexes in suburban areas. These typically consisted of multiple two- story buildings with separate, common parking shelters. Some of the larger apartment and condominium complexes had layouts based on cluster planning principles, with considerable areas of open space. Many included facilities for recreation such as swimming pools and tennis courts. Such shared amenities became increasingly popular, probably more than amenities within the individual living spaces, as builders competed for a portion of the youthful apartment market” (California Department of Transportation 2011:53). According to the evaluation criteria provided in the Arcadia Citywide Historic Resources Survey Report (2016), most residential properties associated with the theme of post-WWII housing will not be individually significant since individually they do not express the patterns of post-WWII development. However, collections of single- and/or multi-family properties may be historically significant if they “are excellent and intact examples of residential development representing the growth of the city during this period” (1945-1970) (Architectural Resources Group 2016:94). It should be noted that the Survey Report does not identify infill multi-family housing such as the subject property as an important property type in Arcadia. People Associated with this Residence. No information was found about the original owner/occupant or builder of the 1923 residence, which according to Sanborn maps had the address 46 Orange Avenue in 1924 and 1932. However, research did not find any other use of this address. Instead, city directories from the 1920s and 1930s list the property as 48 Orange Avenue and then 48 E. Colorado Boulevard. An undated blank permit provides the name H. M. Roth as the owner of 48 Colorado (City of Arcadia var.). Research found that in 1920, Henry M. Roth was a contractor and brick layer (Ancestry.com var.). News articles in 1926 said that the H. M. Roth Construction Company, based in Arcadia, was building 24 homes in Santa Monica (Los Angeles Times 1926). Mr. Roth died in 1934 at the age of 52 (Evening Vanguard 1934). The earliest residents found were Paul J. and Gladys H. Archibald, who are listed at 48 Orange Avenue in Arcadia from 1923 to at least 1932 (Ancestry.com var.). Paul was born in Indiana around 1895 and married Gladys Helen Roth in 1920 (Ibid.). They had at least three children: William, Mary, and David (Ibid.). In 1923, Paul was an auto operator, but by 1928 he was working as a clerk (Ibid.). By 1935, the Archibalds had relocated, and city directories listed 48 E. Colorado as vacant in 1935 and 1937 (Ibid.). In 1939 and 1940, Mrs. Marion P. Cruikshank, a widow, is listed at 48 E. Colorado Boulevard (Ancestry.com var.). Marion was born in about 1883 in South Dakota and in 1936 was employed as a nurse (Ibid.). By 1944, city directories list William E. and Helen S. Hall at 48 E. Colorado Boulevard (Ibid.). In 1944, William was in the United States Army, but by 1948 he was listed as a student and in 1950 building permits list him as the property owner (Ibid.; City of Arcadia var.). Mr. Hall built the duplex in 1950 (City of Arcadia var.). By 1954, William and Helen were living in Azusa and William was working as a draftsman (Ancestry.com var.). In 1956, a building permit lists H. E. Krol as the property owner (City of Arcadia var.). Henry E., a lawyer, and his wife Irene do not appear to have lived at this property. In 1959, city directories list 48a and 48b E. Colorado Boulevard, which appears to be the duplex, as vacant, but 48c was occupied by Mrs. Margaret Muche, an office secretary for Eastman Kodak and widow of James Muche (Ancestry.com var.). Permits from 1977 to 1990 list either Margaret S. Muche or Frank Muche as the owners (City of Arcadia var.). Margaret lived in 48c at least until 1969; she died in 1985 (Ancestry.com var.). In 1960, city directories list Evor R. Gough at 48a and Richard B. Knoble at 48b E. Colorado Boulevard (Ancestry.com var.). In 1962, unit 48a was occupied by John H. Service and unit 48b was vacant (Ibid.). In 1963, Mrs. Barbara Stotter was in 48a and Mrs. Dora McKee was in 48b (Ibid.). In 1965, Mrs. Stotler (or Stotter) remained in 48a, but 48b was vacant (Ibid). In 1969, 48a was occupied by Charles A. Fulgona and 48b was occupied by Virgil C. Cornelison (Ibid.). No additional relevant information was found for these tenants and no other pre-1976 occupants were found. Significance Evaluation. In compliance with CEQA, this property is being evaluated under the California Register criteria and the City of Arcadia criteria for Landmarks (Chapter 1, Section 9103.17.060 of the City’s Municipal Code). The California Register criteria and 1-4 of the local criteria are identical, however, in addition to meeting one of the first four criteria, the (see Continuation Sheet) DPR 523L (1/95) *Required Information State of California - The Resources Agency DEPARTMENT OF PARKS AND RECREATION CONTINUATION SHEET Primary # HRI # Trinomial Page 7 of 9 *Resource Name or #: (Assigned by recorder) 48 E. Colorado Boulevard *Recorded by LSA Associates, Inc. *Date: April 2025 X Continuation Update *B10. Significance: (continued from page 6) local criteria also requires that the property either be listed in the National Register of Historic Places or California Register (criterion 5) or be an iconic property (criterion 6). Because of this additional requirement, the local criteria are more restrictive than the California Register criteria. Therefore, it is possible for a resource to meet the California Register criteria, but not the local criteria. Criterion 1 - Associated with events that have made a significant contribution to the broad patterns of local or regional history or the cultural heritage of California or the United States. The vernacular residence, which was built in 1923, is associated with the theme Residential Development, 1910-1935. Residences associated with this theme are increasingly rare. A residence may be significant under the city’s criteria if it retains “the essential physical features that comprised its character or appearance during the period of its association” (Architectural Resources Group 2016:52). “A residential property from this period should retain integrity of location, design, feeling, and association, at a minimum, in order to convey the important association with the city’s development during this period. A property that has lost some historic materials or details may still be eligible if it retains the majority of the features that illustrate its original style and appearance in terms of the massing, spatial relationships, proportion, and fenestration pattern” (Ibid.). The 1923 residence has been extensively altered (siding, fenestration, and an addition), does not represent an architectural style associated with the 1910-1935 period, and is not visible from E. Colorado Boulevard. For these reasons, it does not convey an association with the historic theme of Residential Development, 1910-1935. It is not significant under this criterion. Because of the addition of the Ranch style duplex in 1950, the property is also associated with the theme of Postwar Residential Development, 1946-1970. In the 1960s, young adults waited longer to get married and had children later. Along with a rising divorce rate, this created a demand for single-person households that translated into a demand for multi-family housing. In California, the proportion of multi-family housing (typically condominiums and apartments) grew to become the majority of new housing units built from 1962-1964, and again from 1969-1973 (California Department of Transportation 2011). Overall, the single-family detached house was the predominant housing type during the post-WWII period and the single-family tract is the fundamental unit for postwar housing. This may be why Arcadia’s historic context statement does not identify infill development such as this multi-unit property as an important property type or a type representative of the post-war period. This property is not significant for its association with Postwar Residential Development, 1946-1970. Criterion 2 - Associated with the lives of persons important to local, California or national history. Based on the research discussed above, the property does not appear to be associated with people important in history. Criterion 3 - Embodies the distinctive characteristics of a type, period, region or method of construction or represents the work of a master or possesses high artistic values. The 1923 residence does not embody the distinctive characteristics of a style, type, period, or region. It is a very modest, generic residence that has sustained alterations including an addition and non-original aluminum siding. The 1950 duplex embodies some characteristics of the Ranch style, but it too has sustained alterations including non- original aluminum siding and additions to the west elevation. It is an unremarkable example of a modest, Ranch style duplex that does not rise to a level beyond the ordinary. No evidence was found that these buildings are the work of a master architect or builder, and they do not possess high artistic values. The property is not significant under this criterion. Criterion 4 - Has yielded, or has the potential to yield, information important to the prehistory or history of the local area, California or the nation. The residences on this property were built in 1923 and 1950 using common materials and construction practices. It does not have the potential to yield information important to the history or prehistory of the local area, California, or the nation. In addition to meeting one or more of the above criteria, the local criteria requires that one of the following criteria be met. Local Criterion 5 – Is listed on the National Register of Historic Places and/or California Register of Historical Resources. The online National Register database (current through 2012) and the National Register weekly lists from 2013 through the present, were searched, but no listings for this property were found (National Park Service n.d.a and n.d.b). In addition, a variety of sources were consulted including the California Office of Historic Preservation’s (OHP) Built Environment Resource Directory (BERD), the 2016 Citywide Historic Resources Survey Report, and the Los Angeles Conservancy website to determine whether this property is listed in or is eligible for listing in either the National Register or California Register (California Office of Historic Preservation 2021). No listing for this property was found.

According to the City’s ordinance, iconic means a property that “exhibits the City’s unique character, history, or identity and/or has been visited and photographed so often by residents and visitors to the city that it has become inextricably associated with Arcadia” (9103.17.160 Definitions). This property does not exhibit the City’s unique character, history, or identity and no indication was found that it is iconic. It is not significant under this criterion. *B12.
