National City and the surrounding South Bay area are shown here during a period of significant urban expansion, characterized by the dense residential infill and freeway development of the late 1960s and mid-1970s. The landscape is defined by its transit corridors, including the San Diego and Arizona Eastern RR and the San Diego Freeway, which intersect the older street grids of Chula Vista and Lemon Grove. Deep within the canyons, newer developments like Lynwood Hills and Sunny Vista appear alongside established institutions such as the Chollas Heights Naval Radio Sta and St Michaels Academy. The presence of numerous large burial grounds, including Greenwood Cemetery and Mount Hope Cem, provides a detailed record of the region's communal history. Near Sweetwater Res, the map captures the transition from open canyon lands to structured suburban environments.
