I live in the Silicon Valley (not sure how much that affects) and in a single parent household with income <200000.
I know my stats are a bit low, but I hope that the improvement between sophomore and junior year counts for something. I don’t really have much going on for me right now, but maybe my essays will help my chances. Any help is appreciated and thanks for your time!

What is your CP GPA (SLO uses 9-11th grades) in their GPA Calculation?

You have competitive test scores and are within range with your UC GPA but none of the these schools will be an easy admit. I would add UCR for business since their Business school is highly respected. I would apply to SJSU as a safety and again they have a good business program. The schools on your list range from a Match- UCI and maybe UCD to HIgh Matches (UCSB) and Low Reach (UCSD). SLO could be a Match-High Match depending upon your CP GPA.

Best of Luck.
