Among the unintended consequences of urban renewal were confusing new trafficpatterns, blocked vehicular access to commercial centers, neighborhoods isolated or divided by highways, thedisruption of existing businesses, and the removal of large numbers of minority residents. Also, the closeassociation of urban renewal planning with modern architecture meant that the new construction in theseneighborhoods was of disorientingly different scale and design than what had stood before. The storefronts ofneighborhood main streets were replaced by massive interior shopping malls and their parking lots, and amultitude of small, mixed-use buildings by monolithic office and apartment towers.However, open space – its preservation as well as its creation – was an important tenet of urban renewal.Planners wished to relieve density, pollution, and congestion, and to bring suburban levels of fresh air,greenery, and spaciousness to the city. The new developments resulting from urban renewal almost alwaysincluded parks, plazas, and other outdoor places to provide these amenities, as well as places for residentsand workers to sit, socialize, and eat, and to gather in numbers for concerts, theatrical events, and politicaldemonstrations, which had begun to exert significant pressure on public outdoor spaces during the politicalturmoil of the 1960s.Several factors contributed to the conditions which brought urban renewal to Pittsburgh’s North Side andAllegheny Commons. The Great Depression, followed by World War II, had resulted in a long deferral ofmaintenance to the area’s infrastructure and building stock by 1945. After the war’s end, Federal subsidies forsuburban housing construction, highways, and home ownership, along with urban racial tensions andcontinuing economic decline in the City of Pittsburgh generally, contributed to the abandonment of much of theNorth Side (along with other, formerly comfortable city neighborhoods) by much of the white middle class. Asbusinesses followed their clientele to newly-built suburban communities with less traffic and ample freeparking, urban neighborhoods such as Pittsburgh’s North Side became seen as “blighted.” Old buildings,outdated infrastructure, excessive density, and inefficient traffic patterns were all identified as culprits to beremedied.In the early 1960s, the Urban Redevelopment Authority of Pittsburgh (URA) authorized an urban renewalscheme for the heart of the former Allegheny City on the North Side. Ultimately, 518 buildings weredemolished and replaced by offices, apartment buildings, and a shopping mall called Allegheny Center. Mostof the demolition and new construction took place in the historic core of Allegheny City. The neighborhoodsbeyond the outer boundaries of Allegheny Commons more or less successfully resisted wholesale eradication,opting instead for longer-term, incremental revitalization strategies. In terms of its open space agenda, theurban renewal plan for the North Side reduced density and introduced several plazas and a small, new publicsquare, called Ober Park, to the core of old Allegheny. But the planners’ primary open space initiative wasfocused on the neighborhood’s existing well-used but deteriorated park, Allegheny Commons.To revitalize Allegheny Commons, the URA hired the landscape architecture firm of Simonds and Simonds todevise a plan for West Common, the park’s most spacious area, in 1966. John Ormsbee Simonds, whofounded the firm with his brother, Philip, was an influential modernist landscape architect, environmentalplanner, and educator whose projects included Mellon Square in downtown Pittsburgh, Chicago’s BotanicalGarden, and 20 master-planned towns in Florida, including Miami Lakes and Pelican Bay. Simonds andSimonds flourished during the post-World War II boom and took part in the Pittsburgh Renaissance, usingmodernist forms and materials to design two major public spaces, Mellon Square and the Equitable LifeInsurance Plaza, in downtown Pittsburgh during the 1950s. Simonds and Simonds grew from its founding as asmall residential firm to a large, multi-disciplinary planning and design practice, earning regard for its work indesigning and planning recreational facilities, parks, and open spaces. This led to a commission in AlleghenyCommons during the 1950s, in which John Simonds partnered with architect Lamont Button and the Director of24
