1915 Map of Hayward

About this map

Salt production and rail transport define the East Bay shoreline in the years following the turn of the century. Large operations like the Union City Salt Works and Crystal Salt Works occupy the marshy edges of San Francisco Bay, while a network of landings—including Mulford Landing, Roberts Landing, and Patterson Landing—connects the tidal sloughs to maritime trade. Inland, the landscape transitions from the developed centers of San Leandro and Hayward to the rugged drainage basins of Lake Chabot and the canyon creeks of Castro Valley.
