Simi Valley and Moorpark define the urban corridors of this Ventura County landscape, where residential developments meet the steep slopes of Oak Ridge and Big Mountain. The map illustrates a complex transition between suburban expansion and active resource extraction, notably at the Big Mountain Oil Field and Oakridge Oil Field. Historic landholdings such as Ormandez Ranch and Berrington Ranch persist on the outskirts, while the community of Strathearn and the Virginia Colony neighborhood reflect the area's diverse settlement history. Waterways like Arroyo Simi and Arroyo Santa Rosa cut through the valleys, providing the geographical framework for the local infrastructure. Local recreation and services are well-documented, from the Sinaloa Golf Course and Sinaloa Lake to the Assumption Cem and the Simi Valley Sanitary Landfill.
