Oregon State is a GREAT suggestion. Definitely check them out.
I just did some quick research on CSUs with particularly popular ES majors based on NCES data. They include:
Cal Poly Humboldt (I love that part of California, again seems like a great location for such a major, although I understand some would consider it remote):
Also Cal State Channel Islands (again just feels to me like a super cool location for this, although I understand its smaller size and more isolated setting might not be for everyone):
Monterey Bay also has an obviously cool location, and then a pretty interesting twist on the major:
Others that popped up included “usual suspects” like San Diego State, San Jose State, and Long Beach.
Anyway, point being there seems like a lot of possible options for more likely California colleges that would be good fits academically, and might be in some pretty cool locations (depending on your preferences, of course).
