Humboldt, Chico, and Cal Poly SLO are arguably the most traditional and residential. They aren’t commuter schools, for the simple reason that they aren’t located within commuting distance of any significant urban areas. So the vast majority of students live either on campus or nearby in town. The presence of so many students in these relatively small communities creates a fun college town vibe.
SDSU has more commuters, but it is a relatively large school, and there are enough residential students concentrated in the College Area to create a student-oriented neighborhood with a similar vibe.
Sonoma, Channel Islands, and Monterey Bay have a lot of residential students on-campus, but don’t have much in the way of student-oriented neighborhoods or services in the adjacent off-campus areas. Some people find the vibe to be lacking.
