Yes, look into Chapel Hill. A major in public policy or geography coupled with their minor in city and regional planning might suit you, I think.
ECU offers an undergraduate program in planning that may interest you.
Apply to the colleges you like along with some in-state options. Once/if you get into several of them, you can compare costs and make an informed decision.
If the OP can get a BA/MUP at USC in three years with generous financial aid, that may be a better deal than doing two years of college and then another two years getting a master’s in an [accredited planning program](Promoting Excellence in Academic Planning Programs | Planning Accreditation Board). A lot depends on how the financial and/or merit aid shakes out.
Financial aid can be rather limited for professional degree students, and graduate loans, unlike undergraduate loans, are not subsidized.
