Looking at Cal Poly SLO, Cal Poly Pomona, USC, Chapman, UC Santa Cruz, Santa Clara University, U of O, Syracuse

oh and Boston University and Northeastern

https://www.universityofcalifornia.edu/infocenter/freshman-admissions-summary indicates that Merced is probably a match, Riverside is probably a high match / low reach, and all other UCs are reaches or unrealistic reaches.

CPSLO and CPP are the only California publics with 5-year BArch programs. CPSLO is a reach; see https://admissions.calpoly.edu/prospective/profile.html . CPP is less obvious, though both the campus and the architecture major are impacted.
