Through a case study analysis of the Central Park placemaking initiative in Winnipeg, this Major Degree Project explores the process of collaborative planning with new immigrant communities. While existing research examines the potential of placemaking to promote physical improvements through collaborative planning, we know less about whether placemaking initiatives achieve the long-term social outcomes associated with collaborative planning theory. Located in downtown Winnipeg, Central Park is surrounded by a diverse multi-cultural community, consisting of many new immigrants. In 2008, the CentreVenture Development Corporation launched a placemaking initiative to revitalize Central Park. The community was a key collaborator in the planning and design process. This thesis examines the long-term social outcomes of this initiative. The main research methods for this project include key informant interviews, and archival and secondary source analysis of existing data. The research finds that collaborative planning processes offer the potential to promote sustainable inner city neighbourhood revitalization. Placemaking through collaborative planning can develop new institutional capacity for participants. By developing and harnessing relational, intellectual and political resources communities can mobilize co-ordinated action toward future initiatives. The findings of this research advance the literature and understanding of collaborative planning processes, particularly within the context of placemaking with new immigrant communities. This thesis adds to the literature of inner city neighbourhood revitalization and collaborative planning theory. / October 2015
