2012 Map of Ontario

About this map

Claremont, Montclair, and Upland are centered in this highly developed Inland Empire landscape, reflecting the suburban expansion and academic clusters of the early 21st century. The map highlights significant educational institutions such as Claremont Graduate University and the Western University of Health Sciences, alongside local landmarks like the Cable Airport and the Mission Tiki Drive-In Theatre. This era of the region’s growth is characterized by a dense grid of residential streets and arterial roads like W Arrow Hwy and San Bernardino Rd. A notable remnant of earlier land use is found at Voortman's Egg Ranch near the southern boundary, while the presence of the Metrolink rail line underscores the area's transition into a major commuter hub. Water management is visible through engineered features like the San Antonio Creek Channel and the Ontario Reservoir Number 1.
