The 11th Street Bungalow Historic District exemplifies, symbolizes, or manifests elements of the cultural, social, economic, political or architectural history of the City. Although the Historic District is located in the original town of Santa Monica and the lots were recorded during the 19th century, this section of town was the eastern "frontier" and was not developed until the early 20th century. By 1891, the north and eastward push of the residential district was well underway. In 1898, the first high school, Lincoln, was built at Oregon (Santa Monica Boulevard) and 11th Street and this block has remained an educational facility ever since. In 1902, only one house had been built on the block; by 1909 sixteen wood frame cottages had been erected. Much of this early development and residential growth was directly linked to the expanding network of streetcar lines in the City and nearby Los Angeles, which enable suburban growth outside of the City's central core. Three of these early homes, all hipped roof, turn-of-the-century cottages survive: 1233, 1239, and 1259 (1107 Arizona), although 1233 was modified to its current American Colonial Revival appearance around 1923 and 1239 has lost integrity. In 1911/1912 respectively, the 1221-23 and 1229 residences were added. Both were developed in the Craftsman style. By 1918, the block was fully developed, with additional Craftsman bungalows filling in the empty lots, reflecting the popularity of this form of development during the first quarter of the twentieth century. The final contributing structure, 1115 Arizona Avenue, was built in 1925. Consequently, of the ten properties in the district, 5 have substantially intact improvements that date from the area's period of significance (1905-1925) and fall into three property types/architectural styles: hipped roof cottages from the turn-of-the-century era, Craftsman bungalows from the teens, and the small, Spanish Colonial Revival style bungalow, located at 1115 Arizona Avenue. A combination of factors contributed to the area's desirability, including the beach accessible living, temperate climate, the local entertainment industry, tourism, adjacency to good schools, thriving downtown, and accessibility to affordable and efficient transportation. Like much of the surrounding neighborhood, this block of 11th Street was built for the middle and working class with moderate incomes. Because of their relative economy, bungalows were the preferred housing type to respond to the growing need for affordable housing during the 1910s and 1920s. Many of the residents were active and contributed to the City and Southern California via education, construction, commerce, and movie technologies and they exemplified the proliferation of single-family dwellings in the Santa Monica Townsite. Following the real estate boom of the 1920s, many of the property owners built second units behind or adjacent to their main homes for extra income or extended family. Given this, the district reflects an important aspect of the City's overall association with the middle and working class from the first quarter of the twentieth century. These 5 properties are significant for conveying patterns of residential development that shaped the Mid-City neighborhood of Santa Monica in the early decades of the twentieth century. Each of these properties contribute to the scale, continuity, and character of this district. As a whole, their integrity of location, design, workmanship, material, setting, feeling, and association work together to visually and physically convey time, place, historical development and authenticity from its period of significance. The collective low-scale and working-class feeling of the district has been retained as a cohesive whole, even with the development of the noncontributing apartment buildings built in the 1950's. This cluster of pre-1925 homes in the original Santa Monica tract is rare. As such, the district is an early and prime example of middle-class housing in the City and retains an important linkage to a significant architectural period that is rapidly disappearing in the City. Although there have been significant changes to the district since its period of significance identified as 1905-1925, these changes do not unduly compromise the ability of the overall district to exemplify and manifest this City's history by conveying an important development pattern. More specifically, the district does not contain so many alterations or new intrusions that it fails to convey the sense of a historic environment. For instance, the adjoining apartment buildings built in the 1950s extend the vernacular, working class nature of the neighborhood and maintain its low scale. As such, they do not diminish the integrity. The district, taken as a whole, is a microcosm of Santa Monica development. Additionally, while the residential property at 1239 11th Street is no longer a contributing structure due to significant modifications after the Northridge Earthquake, it still maintains adequate aspect of integrity based on location, setting, feeling, and association so as not to detrimentally compromise the overall integrity of the district. Many of the other extant pockets of residential neighborhoods in the Santa Monica tract also developed during this period of significance do not have subsequent infill that maintain this relationship. For all of these factors, this district exemplifies the neighborhood's earliest development and the middle-class in Santa Monica during the first quarter of the twentieth century, and as such, it exemplifies and manifests elements of the cultural, social, economic, and architectural history of the City.
