There are tons of colleges near beaches or lakes with beaches. Most of them will have bio and communications majors. More difficult might be speech disorders and under $30k.
Florida:
Atlantic coast: Jacksonville - U of North Florida, Jacksonville U.
Flagler has a lot of financial aid and she might be able to bring it under $30k
Embry Riddle - mostly engineering but bio and some other classes. They like female applicants.
Florida tech - all kinds of bio. Communications. Not sure about the speech therapy, but they have a big psych program specializing in autism (Doug Flutie on the board because of his work with his son’s autism issues)
Stetson, Rollins (my fav!), Palm Beach Atlantic, St Thomas, Barry, U Miami
The honors college of FAU is in Jupiter. FAU itself in Boca.
Gulf Coast: New College, Florida Gulf Coast, Ave Maria (very catholic, so a very niche school, but beautiful), U of South Florida (2 campuses), U of Tampa, U of West Florida in Pensicola)
For most of Florida, it is 4 hours or less across the state, so it is likely one could be on a beach within an hour from most college campuses.
Maryland has schools on the Eastern Shore (Salisbury) which could be affordable.
How about Western Washington in Bellingham? It is a WUE school (I couldn’t figure out where your daughter lives now to see if she qualifies for WUE discount.
