The bridges is a master planned redevelopment and we can't get it done. And we want to do 3 or 4 of these for nose creek, at almost an order of magnitude bigger for each one? The city could end up with quite a white elephant in that case.
For Centre St, you allow organic intensification as is already happening, supported by zoning which makes it much easier to build bigger. It is not rocket science.
As for operating costs of LRT Centre St being higher than BRT, I wouldn't think that based on back of envelop analysis. All the north south buses in the corridor are 81 buses an hour. (2006 numbers, before the BRT was expanded to an all day, all week service if my memory serves me). Given an LRT car can handle about 12x the amount of people as a bus (1 service hour of a bus average boardings [32.4] vs 1 service average of an lrv average boardings [410.7]), is the centre st LRT marginal operational cost over the nose creek alignment really going to me more than the cost savings from the buses? I really doubt it.
Even with all the extra costs of operating a tunnel south of 96th Ave, it would have to be extraordinarily expensive to be more than operating buses on that stretch.

I had a look at the Sunnyside ARP as it has a similar urban structure compared to the lands adjacent to Centre Street and similar to Bridgeland. Over the last 10 years, there has been a population drop of 9.8% from 8,939 to 8,063. This is even less population 'growth' than Bridgeland which at least has had some population growth due to The Bridges.
Zoning is an issue, but there is also the fact that many people might not want to sell, so it could make it very hard to assemble a land package.
So, as much as I'd like to sell it on growth of an established community, I think realistically one would see more population growth in the some 2 square kilometres or so of green space that is potential to be developed. This is what I think is a lower hanging fruit in terms of development opportunities.
And as for operational costs, I would think the operational costs for having a subway versus a at-grade LRT would probably be 25% more or so. I don't think a tunnel's HVAC system, water sumping system, additional lighting throughout the day would be cheap to operate or maintain, also add in some sort of annual tunnel inspection. Things like less weathering might actually reduce number of track repairs.
One would also have to compare the various economic models against the costs of expanding the BRT or HOV network. I don't know what the critical 'break-even' point would be when on a per rider basis when it becomes cheaper to go the LRT route than the BRT route. This number would be nice to know because it would provide guidance on when the LRT subway could be built.
Obviously NCLRT is still a long way off, but I think the best thing to do is to compare the various economic cases as you had mentioned earlier and to determine what is the most cost-efficient option that summarizes capital costs, operational costs, revenue streams, and the value of other developable land opportunities. City administration is already spending money on Nose Creek alignments studies so it's important to address this sooner than later to determine priorities.
There needs to be a realistic framework that goes into these economic models. One could run a P75, P50 and P25 case to capture some of the uncertainty of the assumptions.
Naheed has said that the Nose Creek alignment is not good and would plan for a Centre Street or Edmonton Trail alignment, yet has no economic support for his alternate arguments, and it is also a position that is not supported by previous council administration or by the previous transportation engineering group. Nenshi is intelligent, but by no means is he qualified to offer his own analysis and plan without a independent evaluation.
