Usually I am telling high school students to add a safety or two to their list. I think that I go the other way in your case.
I see several schools on your list that should be solid safeties. U.Vermont (often abbreviated UVM, which comes from the Latin for University of the Green Mountains) is a long way from California, but should be a safety and a good merit scholarship should also be likely. Colorado is a good choice. Again merit aid should be possible (or at least one daughter was offered merit aid there with stats that were lower than yours – admittedly this was a while ago). Wisconsin seems likely (probably not a safety) and is ranked in the top 10 in the US for mathematics. I am guessing that “Udub” is Washington (probably not a safety) mostly because Wisconsin is already on the list and Waterloo seems less likely. I would expect that at least some of the UCs would be safeties (not the highest ranked ones but that is okay). UC Berkeley is of course not a safety at all but is excellent for applied math if you get accepted, and should be a relative bargain for an in-state student who does not qualify for need based aid at top private schools.
Brown is a reach, but I think a reasonable reach.
I am going to recommend that you add an application to Stanford. It is of course very good for mathematics, and you are a very strong applicant. Stanford would be a reach, but does not seem completely impossible given your excellent results from high school.
