The Pennsylvania Avenue Development Corporation (PADC) was created on April 17, 1973. President Nixon named Elwood Quesada the PADC's first chairman, and the corporation's board of directors had its first meeting in June. The revised Owings plan for redevelopment was immediately called into question by John Woodbridge, the PADC's new staff director and an architect in Owings' firm. Upset with the way the massive, Brutalist-style J. Edgar Hoover Building disrupted foot traffic and retail trade along Pennsylvania Avenue, the PADC instead proposed a much stronger emphasis on retail and housing in the new master plan. Among the earliest projects it approved was Market Square, a mixed-use development on the north side of Pennsylvania Avenue NW between 7th and 9th Streets NW that contained housing as well as retail areas and included space for a new memorial. The PADC laid out its preliminary plan for redevelopment by March 1974, and approved its final plan in October 1974. The Willard Hotel, Old Post Office Pavilion, and other historic buildings on Pennsylvania Avenue were retained and the underground expressway removed from the plan.
