A plan to transform a Harvard Square retail property that has had multiple previous redevelopment efforts fall through is set to be revived with a public hearing May 24.
The plan, a vertical expansion of the Crimson Galeria retail property at 57 John F. Kennedy St., would add three floors with 40 rental units on top of the existing two-story structure. Filed March 30 with the Cambridge Planning Board, the proposal would include eight affordable units.
