You are correct that the UC’s will most likely be close to full pay at $60K/year to attend. You might want to look a Pitzer/Pomona and Claremont McKenna colleges (3 of the 5 Claremont Consortium) which has an excellent Environmental Analysis program. They are private LAC’s which may give decent FA.

Also look at Santa Clara University although their FA is not usually great.
