Colleagues mourned Mr. Wallace's passing at the University of Pennsylvania, where he taught planning and urban design for 17 years.
''David Wallace was a giant in his field," said Gary Hack, dean of Penn's School of Design. ''The work he did on the Inner Harbor in Baltimore was a model of how cities should revitalize their waterfronts."
In 1963, Mr. Wallace and three partners -- Ian McHarg, William Roberts, and Thomas Todd -- created the conceptual plan that was to be the blueprint for three decades of rebuilding along Baltimore's once-grubby waterfront.
For 25 years, their firm helped fill out that initial vision, designing promenades, piers, and bridges and setting guidelines for private development. Today the project is considered one of the great US urban renewal successes.
Mr. Wallace's work in Baltimore won his firm a job in New York in 1965 writing a master plan for a redevelopment of Lower Manhattan to complement the then-ongoing construction of the World Trade Center.
The plan's central ideas included creating a new residential community at the tip of Manhattan, easier public access to the waterfront, and the depression of the area's elevated expressways.
