The traditional urban layout of Vancouver was reminiscent of a small-town. Grid-iron patterned streets were lined with single-family dwellings, businesses could be found along main streets and industry was concentrated along shorelines and inlets. The 1960s ushered in a shift towards higher densities through high rise residential buildings in the downtown core. In the 1980s, redevelopment of brownsites (former industrial areas) for condominium development in the False Creek region was a result of it being the site for Expo 1986. Previously, this area was the heartland of industry and had begun to deteriorate as industry shifted. After the Expo the site was acquired by Hong Kong billionaire Li Ka-Shing for $320 million and a numerous residential luxury developments followed suite. These developments promoted a tone of sustainability that were supported through planning documents such as Livable Region Strategic Planning (1996). Urban planning strategies such as Smart Growth stressed environmental goals could be achieved through the provision of walkable and mixed-use urban areas which would reduce urban sprawl. Critiques of Smart Growth highlight the often ignored equity aspects of the strategy as they often ignore low-income residents. Housing affordability became an issue during 2001-2007 as the price for a typical two-bedroom in the west end of Vancouver shifted from $260,000 to $650,000. In 2008, the city council accepted EcoDensity as a solution to housing affordability which promoted further densification of downtown and surrounding neighbourhoods. EcoDensity is the solution to housing affordability rather than provision of social housing. A number of towers were constructed in the downtown Eastside displaced approximately 4,000 low-income residents from June 2007-January 2008. Critiques of EcoDensity, suggest that the strategy does not account for enough citizen input in planning measures.
