Recently the question around the amount of space taken up (exclusively) by single detached houses has show up on my Twitter feed citing that SFH take up 70%, 66%, and 57%, 56% (timestamp 3:50). I personally have thrown in 34% as a contender. And, just for the fun of it, by the end of this post I will have thrown 33% and 28% and my favorite, 81%, into the mix.
Ever since I played with the LIDAR-generated building height data I thought that I should use that to map gross floor area (GFA) and floor space ratio (FSR). Gross floor area is the total floor area inside the building envelope. So for a three storey building, it is the area of the footprint times three. Floor space ratio is the GFA divided by the area of the parcel it sits on.
The other day I saw that Downtown brings in 23% of CoV tax revenue but only makes up 5% of the city area. Intrigued by that I decided to add a ‘Tax Density’ layer to my Vancouver Assessment Map. The idea was to try and understand the tax revenue generated by different areas in Vancouver. The data is already available in the CoV open data property dataset so it would only take half an hour to ad it to my map.
