I'd rezone the entire Macleod Trail corridor for high density, would love to see it become somewhat of a Kingsway-style street (a la Burnaby)... as I believe that is the best we could ever hope from Macleod.
Would also love to see Sunnyside and Hillhurst both rezoned for high density. Would prefer to see both as mostly 6 - 10 storey towers, with a couple of 10 - 16 storey towers in there.
Along Centre Street North, I'd prefer to see the entire corridor south of 40 Avenue lined with well-scaled 4 - 8 storey buildings, with the area in the vicinity of the intersection of 16 Avenue including buildings 15 - 20 storeys, with the intersection itself having buildings between 25 and 30 storeys. Everything between that and the Centre Street Bridge would be between 5 and 10 storeys.
I'd also love to see Crowfoot Crossing as an ocean of skyscrapers tapering to the west, offering most of the residents amazing views of the Rockies.
