Oak Park is in Ventura County. The nearest CSUs are Channel Islands and Northridge. Channel Islands is not impacted, and lists “State of California” as its local area. Northridge is impacted and no longer includes Ventura County in its local area. Northridge does show what last year’s admissions thresholds were at https://www.csun.edu/prospective-students/freshman-impaction .
Other non-impacted CSUs are Bakersfield, Maritime Academy (but no CS), San Francisco, Sonoma, and Stanislaus.
The non-impacted CSUs will admit if the major is not impacted (CS is not impacted at the above-named campuses) and the applicant meets minimum CSU admission requirements.
