TARC will save a seat on every bus in its fleet in remembrance of Parks and her contribution to the civil rights movement.

The proposal includes a 1,000-seat main stage auditorium, a 500-seat recital hall, and a 300-seat flexible learning stage.

The "first concepts" were unveiled Thursday, suggesting possible visions for the 51-year-old downtown plaza that Mayor Craig Greenberg has pledged to remake.
