Founded on the prairie in 1885, the city of Calgary has sprawled to its present population of one million people. In 1914, the General Hospital was built on the south edge of the Bridgeland-Riverside community. Overlooking Calgary’s downtown, it stood for almost a century, symbolically significant yet physically severing the community from the city. In 1998, it was demolished. A national competition called for the development of a sustainable, transit supportive and pedestrian-friendly community on the site. Bridgeland-Riverside is an old neighbourhood of modest houses nestled beneath a bluff, fronting onto First Avenue. Square blocks distinguish this street, which is intersected by a pair of unique elm canopied streets: a remnant of a 1912 City Beautiful Plan designed by famed architect Thomas Mawson. The competition brief was to transform the hospital site into a sustainable community that integrated the surrounding neighbourhood. A skeptical community, scarred by the loss of the hospital, was immersed in the design process. A series of charettes exposed them to a variety of building typologies, ultimately convincing them that if properly implemented, an appropriate density of an additional 2500 residents on the 37 acre site would support the renaissance of the community. Bryant Park, surrounded by multi-storied buildings, served as the park precedent. The intersection connects old and new: the tree-lined streets extend through the reestablished blocks to the new park, built on the hospital footprint. A major urban design initiative of the Master Plan is the extension of the two tree-lined corridors (a function of the Mawson Plan) into the Park as a major built promontory and as a pedestrian stairway. Together these elements frame a new soccer field, designed for local use. An existing park was separated from the community by the Hospital, and thus was used primarily as a regional park. Our intent was to reclaim the park for local use. Forthcoming phases each focus on a small public square that connects visually to the central park. Density and height increase the closer the development gets to the downtown core.
