In the next 30 years Metro Vancouver is projected to grow by about 1.1 million people.[1] To understand the impact of this growth we will use the West End as an illustration. Pictured below, the West End is a residential area primarily consisting of mid-rise and high-rise apartment buildings. Before the 6-story building cap was lifted in 1957 the West End mostly consisted of detached housing.[2]

Using the population growth projections for Metro Vancouver, we can determine the size of the neighborhoods that would need to transition from single family residential to West End equivalent densities in order to accommodate this growth.

Table 1. Metro Vancouver population growth projections SUBREGION POP. 2011 POP. 2041 +POP. 2011 – 2041 +%POP. 2011 – 2041 1.

For the baseline density in this calculation we will use Hastings-Sunrise, a neighborhood in Vancouver that primarily consists of detached housing. Using the difference in population density between Hastings-Sunrise and the West End we can determine the size of the densified residential areas required to accommodate the population growth.

West end population density: 21,830 / km2 [7]

Hastings-Sunrise population density: 4,190 / km2 [7]

The results are calculated in Table 2 below. To give a sense of proportion the results are compared to the 2.0 km2 [8] area of the West End and the 5.8 km2 [9] area of the downtown Vancouver peninsula from Main Street to Stanley park.

The image below shows the size of the densified areas required in the sub-regions of Metro Vancouver. The locations selected are primarily single family detached residential, but are otherwise arbitrary. The areas are intended only to give a sense of the scale of residential redevelopment that will need to occur.
