The Puente Hills and La Habra Hills dominate the center of this landscape, acting as a natural divide between the burgeoning residential developments of the Los Angeles Basin and the industrial corridors of the San Gabriel Valley. During the early 1960s and into the 1980s revision, this area transitioned from agricultural and petroleum-producing land into a dense suburban sprawl. Significant petroleum infrastructure remains visible in the Brea-Olinda Oil Field and Whittier Oil Field, reflecting the region's deep ties to the California oil boom.
