1993 Map of San Mateo

About this map

The Andreas Rift Zone carves a distinct geological path through the heart of the Peninsula, separating the urbanized corridor of San Mateo and Burlingame from the protected waters of the Lower Crystal Springs Reservoir. This 1993 revision, based on contours from 1946, illustrates the intense suburban densification of the late 20th century. While residential blocks of Hillsborough and Belmont fill the hillsides, the map captures specific cultural institutions like the Bay Meadows Racetrack and the Fiesta Grounds (Fairground) before later redevelopment changed these local landmarks. Along the San Francisco Bay shoreline, the engineered landscape of Foster City appears with its signature network of lagoons and waterways, including the Brewer Island Seal Slough, standing in contrast to the natural mudflats near Coyote Point. This record is particularly valuable for genealogists and local historians, as it marks numerous cemeteries and sanitaria including St Johns Cemetery and the Alexander Sanitarium.
