To your first point, it isn't so much that there is a height limit on moving people, its more that keeping up with these densities is difficult. My argument is essentially that if there is demand for 1000 units, that it would be better to spread this over ten 100 unit buildings than two 500 unit buildings. The reason is that transit is better spread across these 10 buildings than it would be for 2 buildings. There is a certain demand for living in Hamilton, and if we want the city to grow more sustainably while also generating livable places to live outside the core, we need both highrises in downtown and midrises elsewhere.
Highrises of epic proportions look nice, but take demand from other locations the city should be focusing on. They do not generate a community, make it difficult to keep up with transit and are not great psychologically for humans.
Again, I think we agree on nearly everything here, except height alone. I think an obsession with height for heights sake is as bad as limiting height for Nimbys. I think the limitations in downtown are fine, the issue is that the planning policy for the rest of the city is terrible. Downtowns policy is terrible in the context of the rest of the city.
Any major road, be it Concession, Ottawa, Kenilworth, Parkdale, Barton, Cannon, Upper Wellington, Upper James should all be zoned for 3-4 storey minimum, with 8-10 storey as of right with bonusing available for higher heights. There should be limitations on parking on these streets and no surface parking similar to downtown.
The issue isn't a height limit downtown in my opinion, its that the rest of the city has bad planning. From friends who have done cost analysis on different heights of buildings, it made me form this opinion, because to put it simply, height to price per unit is not a linear function. There are a whole bunch of factors that cause certain heights to be less financially stable than others.
Having been dealing with the city for a while now with various issues, I honestly don't think Jason Thorne is the issue. It's the city not allowing him to properly plan anything outside the downtown. I have spoken and discussed many of these issues with planners from Burlington and city staff from Kitchener. Thorne is a great addition to the city, the man is right in his understanding of height limits, and how they affect property speculation and the power they give the city with bonusing. The issue is that our politicians and staff are regressive and don't think.
With the 4 recent midrise failures, staff recommended denial on 2 which council voted against, and recommended approval on 1 which council voted against. These 3 midrises could have held the quantity of people that a single 35 storey tower would hold. Instead they deny that, and will approve a 30 storey tower downtown.
This is bad planning, plain and simple. This cap was designed by a planner, and is being used by a ignorant council in the wrong way. Unfortunately, planners can't force the hand of council. There is also the situation of demand and supply. The demand right now is artificially high because of the low supply. Taller towers could indeed provide this supply, but this isn't Toronto, demand does have a limit here. If we fill tall towers with people, midrises won't be able to develop as demand won't be there. You can see how many highrise and midrise developments are dragging their feet because of slow sales. RC3, Steel City Video, Connolly, and others are sitting waiting for demand to pick back up. When it does, a ton of people will go to a very small area, and businesses that already exist will have more customers but vacant units further out will remain empty.
Extremely low density in some areas, with extremely high density in others is bad planning practice, and while you bring up that my European example is a bad one, I disagree, because we should be trying to emulate that success in European cities. Many North American cities are doing exactly that, and even in Toronto, midrise areas are flourishing.
Hamilton is like a micro version of Ontario. If we look at Ontario, one area is desirable and has jobs and is accessible and therefore expensive and that's Toronto, while the locations with less jobs, that require a car and is less desirable is Brantford, Hamilton, St Catherine's. Hamilton has James and it has Ottawa, and the exact same thing is happening, where James is desirable, accessible, and has jobs, while Ottawa St is not as desirable, less accessible, and has much fewer jobs.
This is a result of no new growth in Ottawa St area, and has until recently been the same problem in Hamilton when compared to Toronto. Hamilton needs to grow up everywhere, not just downtown. By putting a 60, 70, 80, 90 storey tower downtown Hamilton you slow that from happening. Hamilton's major issue isn't a 30 storey limit downtown, it's that the city doesn't understand what that means.
It means that 30 storeys should be the limit in bad locations for height, and it means that if a developer wants to go higher there should be bonusing. It also means that the city needs to have a comprehensive plan outside the downtown, and not deny 11 storey buildings 1 block outside the "downtown" secondary plan.
The Pier 8 development is a great example of good planning, and would not have been improved by being taller. Toronto's waterfront is much less enjoyable because of the massive height right against the water, and the locations with midrises are much nicer with large walking paths and restaurants and patios. I legitimately think Centre Mall at Barton should have been the same design, and Ottawa St and Kenilworth would have exploded with popularity, especially with Go nearby and LRT bringing people into and out of downtown.
Most people I know that do enjoy living in Toronto live outside the main core, by Ossington, by the ROM, or out by Queen East. I will also add that I agree that Mississauga isn't bad because of height, but again it isn't helped by it. My point was that height alone does nothing.
I don't think having no height limit achieves anything, and the reality is that Hamilton's downtown core has a limit in size. It's unlikely we will be tearing down old victorian homes east of John St anytime soon to build condo buildings. Even at John and Barton, there is a townhouse complex being build, not even a midrise. If we go too tall, then we will have extremely tall towers against low density residential which is bad planning as well.
Again, my point with agreeing with the height limits for now is because I don't think that if we suddenly allowed unlimited height Hamilton would get significantly better. Hamilton's issues revolve around leadership, bad planning in general outside the downtown core, which mostly has a decent secondary plan, and infrastructure.
Infrastructure can be improved with property taxes, but is helped more by property taxes and people using it, and the best way to get the latter is to increase density around transit corridors, which is all I am really arguing for. Also your points are better received by me, than blindly wanting tall towers which is what many on here naively want with the assumption that is will solve everything.
Also my comment is much more rambly, but I'm too tired to edit. I hope to see you continue to advocate for height where it makes sense, and appreciated your design around Jamesville, I do like that design more, as I agree that it a good location for a bit more height. I think it illustrates where we agree and disagree. Firstly I don't like space in the middle of buildings as this is a known problem area in older developments and become dead zones. I personally think the corner of Strachan and James is too tall, and half the height should be taken to the corner Ferrie and James, to match the kitty corner. The middle section should be a market square type design similar to what you can see in Brantford's Harmony Square with water feature and ice rink and a few commercial units. I think this would get a better bang for your buck than just a triangle in the middle which would feel exclusive to owners in those buildings.
