Harborplace redevelopment plans could erase McKeldin Square. Some McKeldins aren’t pleased.

The plan to rejuvenate Baltimore’s Harborplace has rankled relatives of a man whose vision 60 years ago inspired redevelopment of the Inner Harbor. Four family members of former Baltimore Mayor Theodore McKeldin are asking the Commission for Historical and Architectural Preservation to intercede in the once-in-a-generation plan to modernize the city’s central-most public space. They’re seeking landmark designation for a portion of the city-owned property bearing their patriarch’s name, a move that would create another layer of oversight for an enormously consequential project.
