Livermore and Pleasanton serve as the primary hubs in this survey, showcasing the continued suburban and industrial growth of the Tri-Valley region. The map reveals a landscape defined by water management and transit, where the S Bay Aqueduct and the Arroyo Valle traverse the terrain. Traces of older identities remain through settlements like Asco and Radum, while the sprawling residential developments of Dublin and Oak Knoll indicate modern expansion. Local education and aviation infrastructure are represented by Las Positas College and the Livermore Municipal Airport. Along the southern edge, the terrain rises into the Diablo Range, providing a sharp contrast to the developed valley floor. Genealogists will find the locations of St Michaels Cem, Roselawn Cem, and Oak Knoll Cem useful for family research in this part of Alameda County.
