About this map

Industrial expansion and maritime logistics define the southern California coast in the mid-1920s, as shown in this detailed survey of Los Angeles Harbor and the surrounding waterfront. The landscape is a complex network of man-made waterways including the Turning Basin, West Basin, and the engineered Cerritos Channel. Land use is dominated by critical infrastructure such as the Union Oil Refinery and the Southern California Edison Co Power Plant, supported by a dense grid of Southern Pacific and Pacific Electric rail lines that connect the shipping slips to the interior.

Residential and military life centers on the developed grid of San Pedro and Wilmington. The strategic importance of the heights is evident at Fort McArthur Upper Reservation and the lower batteries near Point Fermin. To the east, the natural wetlands of Bixby Slough and the Salt Ponds provide a sharp contrast to the intensive dredging of Terminal Island and the expanding shipping facilities at Fish Harbor.
