I don’t agree that Irvine and Davis can be considered safeties; I think they are matches - low matches at best. Merced would definitely be a safety, and Santa Cruz is a low-match/safety.
Are you in NorCal or SoCal? There are good, affordable safeties among the WUE schools, but if you want to be close to home, then it depends which of the adjacent states you are closer to. Portland State, Arizona State, Northern Arizona, U of Arizona, and the U of Nevada campuses (Reno & Las Vegas) would be ones to look at for starters. Colorado State is farther but an excellent engineering school and a great financial deal with WUE so perhaps worth a look.
Oregon State is a great engineering school (and has an honors college) which used to be a WUE school but isn’t anymore; however, they have bumped up OOS merit aid so they could still be worth looking at.
If you’re 100% sure about engineering, you might want to look at Colorado School of Mines. It’s expensive as an OOS public (around $53K total COA) but still considerably cheaper than full-paying for a private U, and it is a comparable experience academically to small private engineering schools like RPI and WPI (not quite as lofty as Caltech and Mudd but not that far off in terms of rigor; and you don’t sound like full-paying for Caltech or Mudd would be a realistic financial option for you even if you could get in). As a woman with your stats I think your admission chances are excellent. It can be an amazing place to go to college if you’re sure about STEM and like beautiful natural environment and a close-knit campus community.
Here is the whole list of non-California WUE schools that offer MechE. All are a great financial deal (most cheaper than UC at 150% of in-state tuition) and there are many excellent engineering programs. Many have excellent honors programs as well.
