There are two distinct parts of University City divided by Rose Canyon, featuring the Rose Canyon Open Space preserve, and railroad tracks passing through it. South of Rose Canyon lies the older part of University City, built out in the 1960s-1980s and historically referred to as University Square, centered on Governor Drive. It is a mostly residential neighborhood along Governor Drive with many single family homes. In this area, just southwest of the Governor Drive exit from I-805 is a commercially zoned area containing office parks with low-rise buildings.
