The hills east of Napa transition from agricultural flats to the steep ridges of the Vaca Mountains in this early 1950s survey. Significant land use is evident near the Napa State Hospital and the nearby Coombsville settlement, which sits along the valley floor. The map highlights the area's early water infrastructure, including reservoirs like Lake Frey, Lake Madigan, and Lake Curry, complete with an Intake Tower and spillways. These water bodies, along with Green Valley Falls, signify the importance of water management for the surrounding Wooden Valley and the developing Napa corridor.
