Have you visited Corvallis?
It is a nice college town, with the great advantage of being immediately adjacent to campus, similar to the arrangement at UC Davis. Corvallis has shops, restaurants, coffee shops, farmers market, etc. My kids both prefer “urban” schools, but they both thought Corvallis would be sufficient because it’s totally walkable / bikeable from campus.
Unlike the city of Berkeley where I live, Corvallis still has actual movie theaters, including Darkside Cinema, which is the sort of local independent movie theater every college town should have. (Berkeley has one movie theater left… it’s really small and not adjacent to campus. The others have all closed.)
UC COA is currently listed at $45,234 for residents, although the actual cost will vary by campus.
