My thoughts are if Saskatoon wants more in-fill and have more densification instead of urban sprawl requiring more expensive highways with interchanges and bridges for the city, Saskatoon needs to take advantage with developers like Urban Capital & Victory Majors and foster even taller developments than this.
Reducing the size or simply forcing residential and office developments to the outskirts of the city makes the costs for infrastructure for the city even more expensive. Nimbys may not want development in their beloved areas of the city but if they had to put money where their mouth is and have to pay extra taxes to make up for lost taxes when new construction is deterred, they may come to the realization that they play a part in urban sprawl too.
I'm not entirely sure what the difference to anyone not living or using these future developments for the construction to be 12 storeys or 14 or 17 etc. The extra traffic in the areas is only a small fraction of what it is already there and some of these developments have no sunlight shadow affect on surrounding neighbours houses what-so-ever. Saskatoon will never graduate into reputable city status & get lost in the dust of similar sized cities like Kelowna & Regina etc if it can't build developments like those cities are currently doing.
I did a quick graphic of what the scale of a 17 storey building would like on that plot of land. Do you think it's out of proportion for the neighbourhood, keeping in mind that it's in a part of the city that's zoned for high density development?
