About this map

San Francisco Bay dominates this late-1940s survey of the Peninsula shoreline, revealing an intricate network of waterways and industrial salt production. The landscape is defined by extensive Salt Evaporating Ponds and a complex system of tidal channels, including Steinberger Slough and Belmont Slough. This era captures the early development of infrastructure such as the San Mateo Bridge and the Bay Shore Highway as they began to reshape the western shore of the bay.

Maritime and aviation history are well-represented by City Harbor, Yacht Harbor, and San Carlos Airport. The map also details several large landmasses within the marshlands, notably Bair Island and Greco Island, and marks the broadcast presence of Oradio Sta KNBC. This document provides a clear look at the Redwood City Boundary before the significant landfill and residential expansion of the mid-20th century.
