1974 Map of Costa Mesa

About this map

Costa Mesa and Fountain Valley are captured here in a transition point of mid-1970s development, shown through the detailed lens of a 1974 orthophotograph. This aerial survey provides a photographic record of the suburban expansion across Orange County, where residential grids and industrial tracts meet the natural curve of the Santa Ana River. The imagery reveals the density of the built environment just inland from the Pacific Ocean, documenting the precise footprint of streets and commercial centers in Westminster and its surrounding communities. By using actual photography rather than traditional topographic symbols, the map preserves a visual census of the landscape, from the specialized land use in the river valley to the burgeoning neighborhoods that would define the region's late-twentieth-century character.
