Detailed map of Long Beach, California, privately prepared by Southern Pacific Railroad for internal usage.
The map is based upon a "map of J.L. Foster, city engineer of Long Beach in 1906 [and] data accumulated from records of Los Angeles Co, and private surveys by Mr. Foster."
The map illustrates the subdivisions in Long Beach within 1300 feet of the center line of the Southern Pacific Railroad, west of the Los Angeles River. and centered on the San Gabriel River. A significant part of Long Beach is shown in remarkable detail. The progress and growth of the City is quite remarkable over the past decade, in comparison to a map of circa 1900 (see link below).
