I don't disagree that elevated rail, when implemented correctly, is fantastic as pointed out in the vid from the excellent Mr Martin above. Vancouver and suburbs, London and the DLR, Berlin to name a few are all fantastic when implemented correctly and into an urban/suburban enevlope that is fitting.
This is part of the problem with them releasing a rough sketch on a napkin with no actual details. We have a roughed in conceptual sketch that as noted is subject to change pending further study.

10th whilst not perfect, does have residental and commercial along it and yes, shadows.
With no design showing the guideway between stations, will it be a single span such as the existing Sunalta section with a wide gap between the lines or will it be a slimmer version with the tracks basically side by side. Will the guideway extend across the entire roadway, encroaching over the sidewalks or will it be retained within the road right of way. My concern here is'nt around will it cast a shadow, yes it's DT there will be shadows but rather will it block out light and the sky simply over the road (great) or will it also block out over the sidewalk. From Bottlescrew Bills and 1st St across towards 2nd St, theres a fairly busy enterainment strip with bars and restaurants. Whilst obviously having a station near will be be a positive in terms of accesibilty, what impact will it actual have on the streetscape, desireabilty of the establishments. If a wide deck blocks out the natural light and projects a permenant shadow creating a dark, cold streetscape, will that invigorate businesses?
Will the large mature trees along the north side be removed, will they be able to survive in the new enviroment?

The previously mentioned Transit systems that successfully employ elevated rail, I would argue do in a manner that integrates the rail with the streetscape and not simply 'caps' it over the road way.

Skytrain as it runs in Richmond, is perfectly scaled in a way that the guideway fits with the street and isnt forced up againt adjoining structures or with significant negative impact to the pedestrian realm.
There's a wide setback from buildings and the station is built off of the roadway to the side. I understand existing buildings etc may prevent that here but could the station be built over the parking lot that is directly beside the envisoned station or a small parcel of it for the station head, reducing the volume that would be over the road way?

In New Westminster, where the Skytrain is DT, the guideways are again kept to the side of the roadway or intergrated cleanly and intelligently with the buildings. Its not simply dropped into the middle of the roadway. Theres still seperation between guideway and nearby buildings.

Metrotown/Burnaby again has the elevated guideway seperated from nearby buildings and the guideway itself is in its own envelope ( not directly above any of the adjacant roadways or butting up against buildings, impacting the nearby streetscape.)

The DLR in London has significant elevated sections but again, they are built to work with the enviroment and streetscapes that they are placed in.

The same with Berlin, their guideways and stations are built to fit the environment, not just can you put it in there.

The alignement that has been presented, in my opinion when viewed with the above often cited examples, fails to incorporate itself in a manner that is conducive to anything other than, can a line 'fit'.
The Province if serious, should have presented a seriously thought out plan, elevated can work, it just has to be built to the enviroment its being placed in. With nothing concrete in the report ( everything is subject to change, pending further study....) people are concerned (righlty or wrongly) that it will look like the Sunalta elevated section.
And on the subject of noise etc, I think its unfair to equate those living on 10th already as being used to dealing with trains from CPKC. I would imagine theres a difference between a couple of trains an hour, 50 or so metres away to a train every 5/10 minutes, 3-5 metres away. But we dont know, because it was'nt studied. I saw an interview on the news the other day, done under the Sunalta guideway and they had to stop as the train came over becuase of the noise. So if it hasnt been mitigated in a study, people will go with what they know, which in my case is an interview conducted 2ft apart that had to stop becuase of a train going over the elevated guideway.

And if we are including photos of 2nd st, lets include where the line is proposed to go, which is to 7th ave. Its not all office, there is pedestrian realm there too.

With all that said, elevated can work but whats been proposed needs alot of work. The Province stating accept it and then figure out the rest yourselves is beyond ridiculous. Not accepting any cost increases, specifically to the segment that they are redesigning and forcing on the city is political grandstanding and bullying plain and simple. If they were serious, they would have came back with, this is the base, lets now finese it together and see where we get. Lets actually make something that works like anyone of the above mentioned systems.

Instead we get stuck with this cycle of BS.
Apologies for the length, time to rest my fingers....

Why would the province care. Appeasing your supporters. Getting votes. There was no reasonable reason for province to pull funding and cause all this mess besides the above??
Not wanting to see projects developed that fall below a certain cost to benefit ratio? Not that it was expressed exactly as this.

Or the city can take what they’ve been told by the province: elevated on this route and do what it typically does: optimize.

I think you’re getting too granular for the decision at this point.

I understand that for many all that can be compared is document to document. But the choice isn’t that. It is between underground without the province (and likely the feds), or elevated with everyone.
 
How is asking for what the Province dictated, to actually include some sense of details, being too granular?
I explicitly stated I would support elevated but in this current iteration that has to be decided on in short term, that includes limited costing and scoping, I'd be pushing the provider to damn well fill in some blanks or give me assurances.
This is exactly the point to be asking questions not 4 years down the line.

If I had an investor (1 of equal 3) suddenly try and pull shoot and re-write a requirement to there own wants and needs, ignoring any pre-agreed requirements and research of which all 3 parties reviewed and agreed to, you better believe that I'd be pushing them for covering any additional costs that results Soley from their late game changes.
And yes I understand the reduction in scope by the city in July could be seen as one and the same however I view an entirely different alignment using a completely different medium with a bunch of unknowns as a much more significant change.

I don't agree with simply accepting something that is not up to standard because someone is trying to threaten/bully/extort, call it whatever you want, you to go with want they want.
As the Province has repeatedly said, it's a City project.
So I will get granular and ask for specific details.

I can support an elevated but at the same time question such apparent shortfalls in what was presented.
I don't have to blindly and quietly agree.
 
Risk lens proportionality has to be applied here. The city has elevated stations and guideway costed for this project already, just different parts.

Despite being 60% designed the tunnel and underground stations have much higher risk than a 5% design for the downtown/beltline elevated section.

Not underground is so much less risky.

This project many issues arose from thoughts around risk costing, governance and transfer, that I guess the final misunderstandings should come from that too!
 
I'm not debating the pros and cons of each scenario, nor providing a personal preference, but responding to the snarky comments given to people fairly analyzing some of the rational concerns just as they would provide equally for underground and at grade. No scenario is perfect but it's not offside to evaluate them.
This isn't any different than NIMBYism with other developments. The final and lasting outcome is never anywhere as bad as imagined. The construction phase sucks, but it passes - though it truly does suck for small businesses. There was a recent article where Bottlescrew Bill's complained about already having suffered through long construction phases...but I'm not sure how many other small businesses will truly suffer here. Village Ice Cream?

But I agree we latté sippers can be too dismissive of NIMBYs overall. The bad faith hyperbole makes it hard to engage with the genuine issues. It sucks to find yourself on the NIMBY side of an argument where it feels futile (but I guess Glenmore Landing shows us that the hyperbolic crap works!), and when you can't see the greater good argument - but it shouldn't be hard to see with mass transit.

I updated the poll with a new question - Elevated or Underground. I don't believe there's a correct answer only a decision based on weighing out different factors, and it'll vary from person to person depending on the importance of the factors.

I suppose it doesn't really seem to be on the table yet, but I'd hope there could be another option short of cancellation: try to use the federal funding to build it as BRT? I've seen others suggesting this elsewhere, so I'd be curious where it stands here.

I just can't vote for any of these three options. U/G is out of the question as the city simply cannot afford it (with or without the province IMO), and I don't trust the province to maintain their funding commitment no matter how the city proceeds. So for me it boils down to:

1. LRT that terminates south of CP tracks for now
2. BRT (probably less total spend by the city)

Can you clarify exactly what your point is here as you quoted haltcatchfire directly on his point about snarky comments to posters like myself asking questions of the proposed alignment?
Because I and others are asking questions about gaps in the Province's alignment, we are NIMBY like?
What bad faith hyperbole did I put forward to avoid engaging on genuine issues? I stated I support elevated if underground was totally uneconomically viable and even provided examples of where elevated was done well and what we should be hoping to emulate vs whats been quickly drafted in 3 months.
If now isnt the right time to start asking questions that were'nt addressed in the report, when exactly would be?

And to provide context, I live in Mckenzie by 130th. Shepard would be a ten minute walk door to door. A train would be absolutely amazing but I'm not going to grace myself with it, if it means spiting another section of the city with something ill-thought out. If that was the case, Id say ram the dam thing up Macleod and 1st at grade and screw what anyone says, if it means I can get my seat at Shepard.
 
I think the section from 4th to Shepard is the most logical to move forward on. The design is mostly done and the ROW is right there. TOD is already beginning in Douglas Glen and Quarry Park. We’ve purchased trains. The storage and maintenance facility is a no brainer.
That's the crux of this whole line in a nutshell. The business case (for the SE line, ignore the N line which probably makes more sense) exists from the central business district to the burbs in the SE. The most expensive and tricky part is around the CBD, which has hamstrung this project for the better part of a decade now (and been bungled by at least two levels of government along the way). Then in the middle of the SE segment, you have several consecutive stations with close to zero ridership throughout the industrial park areas, killing the business case for the city's most recent proposal to cut a bunch of the south stations. So we end up with this beast of a project, where on paper it makes no sense to invest billions unless you go big and the least capable funding partner probably can't absorb that burden on their own.

Critisisms don't immediately equal against/nimby. It's how projects get refined.

No profound point, the broader commentary on this is just interesting (moreso reddit/etc; the discourse here is quite thoughtful). Many of the very same people who scoff at NIMBYs against rezoning or other developments are strongly taking up NIMBY talking points here. I completely understand the hating UCP part, but there wasn't exactly a lot of enthusiasm for the stub line when approved in late July...more like 'resigned acceptance' from even the staunchest supporters. But the tunnel alignment seems to be back to sliced bread status now.

1. LRT that terminates south of CP tracks for now
2. BRT (probably less total spend by the city)
I added BRT as an option to the poll, as like you mentioned it has been discussed as an option as well.
 
2. BRT (probably less total spend by the city)
It's worth noting that although BRT costs less in the short term, it costs a lot more in the longer term. An articulated bus in Canada can hold around ~110 passengers, while the CAF LRVs will be able to hold around 288. There are articulated bus variants internationally that can carry up to 270 passengers, but I can't speak to those. With the Canadian models, you'd need roughly five articulated buses with five operators to carry the same number of people as a two-car train with one operator. An LRV can last anywhere from 30 to 40 years (although, Edmonton is pushing its U2s to 50), but a bus only lasts 18-20 years if it is given a mid-life refurbishment; meaning you need to replace those buses roughly twice as often as the LRVs. You also need more storage space for all those buses than you would for LRVs, more people maintaining them, and a larger budget for fuel (and I presume parts too, but I could be wrong).

Although specific to Edmonton, this report to Council provides some interesting numbers (bolding is mine):

"A BRT scenario was evaluated with the assumption that articulated buses would be used, which can each accommodate 70-85 people.* For this exercise, the Valley Line LRT is assumed to operate with two 40-meter low-floor vehicles during peak hours, which can accommodate 275 passenger per vehicle, or 550 passengers per train. Therefore, seven articulated buses are required to provide the same capacity as a two-car train. The typical lifespan of an articulated bus is 12 years, whereas a light rail vehicle has a life expectancy of 35 years.

Therefore, to move the same number of riders by bus over the life expectancy of a single two-car low-floor train, a total of approximately 21 buses is required. This also results in a corresponding increase in staff time to operate and maintain the fleet of buses compared to LRT. Generally, LRT vehicles are less expensive to operate on a per-rider basis compared to buses, as the cost to maintain, operate and power a single two-car LRT train is less than that for seven articulated buses.

As a result of these factors, the total life cycle cost of a BRT system over a 35-year period could be 20-30% more than that of an LRT system. As LRT and BRT technology evolves, there may be new vehicle types such as double articulated buses or rubber-tire mounted trains, which may increase the capacity of BRT and make it more competitive with LRT."

Keep in mind that the original plan for the Green Line Transitway was that it'd be upgraded to LRT in roughly 10-30 years; I can certainly understand why the city jumped at the increased funding opportunity to skip all those operating costs and go right to LRT. With what's happening now, would it be worth to go the route that's cheaper now but pricier over time? I dunno, but I get why people find it tempting to at least consider.

*The capacity figure that I cited is different from the report's figure, but mine also comes from a City of Edmonton page.
