1967 Map of El Cajon

About this map

The El Cajon valley and surrounding foothills represent a significant era of post-war Southern California suburban expansion, where residential tracts like Winter Gardens and Bostonia rapidly fill the landscape between the San Diego River and the Sweetwater River. The 1967 field survey, updated with 1975 photorevisions shown in purple, highlights the conversion of agricultural lands into dense residential blocks and public infrastructure. Notable aviation and recreation history is anchored by Gillespie Field and the adjacent Cajon Speedway, while the southern slopes near Mt Helix and Calavo Gardens show a different pattern of hillside development. The map also documents extensive institutional growth, including dozens of neighborhood schools such as Lakeside Farms Sch and Granite Hills High Sch, along with specialized sites like Edgemoor Hospital and the Convent of the Sacred Heart.
