Results

 

After our attempt at running ModelBuilder and the subsequent manual iterations, we produced a series of five maps aggregating our results: visual displays of the remaining available residential areas with average monthly rent prices by dissemination area at the 100m, 200m, 300m, 400m, and 500m buffer distances. We produced an additional map at the 300m buffer level showing only the available residential areas with the lowest rent (less than $750 per month). The results visually displayed by the maps are quantified as areas (in square kilometers) and as percents of total residential area as well as Vancouver’s total area in Table 1.
