About this map

Walnut Creek and the neighboring suburban centers of Concord, Pleasant Hill, and Lafayette are shown here as they appeared in the early 1990s. The landscape is defined by the rapid convergence of residential development against the geographic boundaries of the Briones Hills and Lime Ridge. The map captures a critical period of infrastructure, showing the Contra Costa Canal and Mokelumne Aqueduct threading through the valley alongside established aviation and military hubs like Buchanan Field and the Naval Weapons Station (Concord).

Historically significant land grants are still noted by their traditional names, including Canada Del Pinole and Arroyo De Las Nueces Y Bolbones, reflecting the area's deep Spanish-era roots. For genealogists, the map identifies specific local landmarks such as Lafayette Cemetery, St Stephen Cem, and Diablo Valley College, providing a detailed look at the social and institutional fabric of Contra Costa County during this era.
