it is really unlikely you will make it into any of the UCs with a GPA in the 3.0 range.

Most of the CSUs are going to be open to you. Take a look at SF, Sac, Chico, Sonoma as viable options.
Attending a CC for a couple of years, then transferring to a UC is certainly an option.
Apply broadly and good luck.
