After the war, the Macks wanted to expand the seating capacity again, in a park that was running out of room to expand into. In 1949, they proposed erecting the ultimate spite fence: a new double-deck seating section in right field that would boost the park's capacity to 50,000. The problem was that the home plate-to-right field axis was the shorter dimension of the Shibe block rectangle, and since the new stand could not intrude into the play area, its fascia would have to be in the plane of the existing right field fence while its hindquarters would have to protrude out back, dangling some above the west sidewalk of North 20th Street and forming a covered arcade walkway. The $2.5-million proposal galvanized the 20th Street neighbors against the A's again, and this time the legal team could not overcome the zoning issues.
