About this map

Seal Beach and Huntington Beach anchor the coastline of this wartime survey, showing the Orange County shoreline before the post-war housing boom. The landscape is dominated by the extensive wetlands of Bolsa Chica and a network of water management features including the Las Bolsas Ditch and Bolsa Ditch. These marshlands were then occupied by private sporting estates such as the Sunset Gun Club and the Bolsa Chica Gun Club, highlighting the area's transition from wildlife habitat to managed recreation.

Inland, the agricultural character of the era is evident in the grid of local roads like Heil Avenue and Springdale St. Small settlements like Wintersburg and the presence of the Springdale Sch suggest a rural community connected by the Pacific Electric railroad. This rail line provided a critical link between the coastal resorts and the interior valleys, while the Long Beach Breakwater indicates early infrastructure developments along the Pacific Ocean margin.
