Below you will find a map of the downtown Vancouver core. Pictured in this map you will see purple highlights which represent all remaining surface level parking lots/car parks/parkades.
Adjacent to these coloured plots you will also notice a number which represents the maximum building height in feet for each specific parcel as zoned by the Vancouver view cone and higher buildings policy. Land in the downtown core is becoming increasingly scarce due to stringent height limit standards imposed by city planning officials. These height limits and view cones are designed to preserve views of the surrounding scenery as well as to limit street shadows. Due to the fact that building heights in Vancouver are restricted, more buildings are then required to be constructed in order to meet office and residential demands, thus contributing to the expedient loss of parking space. On the upside, urban density is increased by having numerous smaller towers rather than a handful of taller ones.
Based on current and historical rates of construction in Vancouver, it is my estimation that all remaining parking lots will be fully built out in the next 12-15 years. This is in addition to ongoing and upcoming developments which will see the demolition of current buildings to make way for new developments.
