About this map

The citrus-growing landscapes of Covina and Charter Oak are showcased in this mid-1920s survey, illustrating the transformation of the eastern San Gabriel Valley. The map captures a transition from large rancho-era tracts like Rincon De La Brea and the Diamond Bar Ranch to organized suburban blocks and industrial corridors. Transport infrastructure is particularly dense, with the Pacific Electric and Southern Pacific railroads cutting through the basin to serve the agricultural economy.

Notable institutions are prominently marked, including the Masonic Home and the Protestant Home for Boys, situated on the fringe of the San Jose Hills. Further south, the settlement at Spadra and the Walnut Sta reflect the rail-dependent growth along the banks of San Jose Creek. The intricate contour lines of the La Puente Hills and landmarks such as Buzzard Pk provide a detailed perspective of the local topography before the post-war housing boom.
