Map of Los Angeles County

This impressive overview of the transportation network of Los Angeles County reflects the tremendous growth enjoyed by the region in the first decade of the 20th century. Between 1900 and 1910, L.A.’s population more than tripled (from ~102,000 to ~320,000, with the county nearly keeping the same pace. The infrastructure could hardly keep up. In order to facilitate the rapid suburbanization, the Pacific Electric (P.E.) system spread across the county like spokes from a wheel. These lines, plus several other railroads, composed the primary transit for the masses, as well as the framework for regional growth. Automobile ownership was also increasing thanks to the temperate climate and relatively flat terrain, though only a handful of roads are named within the map. The detailed image also reflects several other important developments across Los Angeles County. The incorporation of the ‘ Shoestring Strip’ allowed the city to annex the towns of San Pedro and Wilmington, allowing for the control of L.A. Harbor prior to the completion of the Panama Canal. The San Fernando Reservoir reflects the southern terminus of the Los Angeles Aqueduct, which would begin flowing the year after publication. The first film studio, Nester Studios, opened in the barely visible neighborhood of Hollywood the year prior (1911). The locally produced map was copyrighted by James Chadwick in 1912 and originally sold for 25 cents, according to the front cover. Distribution was supported by the Hotel Woodward, boldly promoted above the index at the bottom of the page. Printed by the Commercial Printing House.
