1915 Map of San Mateo

About this map

San Francisco Bay and the Pacific coastline of the peninsula define this landscape at a time of significant early growth, as documented in 1914 culture revisions. The urban expansion from San Francisco southward is evident in the development of Daly City and South San Francisco, while established institutions like the Alms House and Industrial School sit near the northern boundary. Inland, the critical water infrastructure of the Spring Valley Ridge is fully detailed, including San Andreas Lake and Crystal Springs Lake held by the Crystal Springs Dam. Transportation networks are dominated by the Southern Pacific RR and the Southern Pacific Interurban, which connect coastal settlements like Moss Beach and Princeton to the growing industrial and residential hubs. Small community landmarks such as Hoyt School and Brewer School provide essential points of reference for local family history research.
