About this map

The Cosumnes River and its network of seasonal drainages define this agricultural landscape in the late 1960s, where the convergence of the Southern Pacific and the Central California Traction Road supported a string of small rail-side communities. Rural life centers on settlements like Clay, Herald, and Centralia, which are linked by an extensive grid of section-line roads such as Grant Line Road and Arno Road. Local education and social hubs are anchored by the Colony Sch and the Arcobe Union Sch, reflecting the distributed population of family ranches.

Water management and terrain shape the local economy, visible in the numerous wells and irrigation features like Windmill Draw and the Laguna Creek system. The map documents the boundary between Sacramento and San Joaquin counties, tracing the historical Grant Boundary through an area of transitioning land use, where established homesteads like Bottimore Ranch and Valensin sit alongside modern infrastructure such as the Colony Woods Substation.
