Normally I am not for this kind of decision making - but it would please me greatly to see that stretch of homes expropriated for a big fat elevated transit line.

That sounds a bit vengeful.... but I would say the same thing a bit more clinically. Wherever we build transit in the GTA, density has to follow. That doesn’t imply towers, but at minimum it implies a buildout to the full Avenues 8-story scale. That ought to be applied all along Bloor-Danforth from Kennedy to Kipling. Similarly the zoning for multiple-family dwellings must be increased, allowing smaller but still multi-family structures anywhere within a few blocks of a subway station.

I live in such a a single family home neighbourhood with a short walk to the subway, and all I see being constructed around here are monster homes. That has to stop. Triplexes, ok. One option is to impose surtaxes or development super fees on any new housing construction in that proximity zone that doesn’t offer multiple units, owned or leased. Or just raise tax assessments. Change the economics so that the people who say “I have money, so it’s my right to buy close to the subway” are outbid by people who say “I will use the same land to house more people”.

So yeah, that kinda dooms the present neighbourhoods close to Eglinton (just as it dooms the Kingsway, and others near Bloor/Danforth). Building transit and then surrounding it with suburbs is a bigger waste than overbuilding a line where a more modest form of transit would do.

I don't think any expropriation would be necessary with an elevated transit line on Eglinton West. Where the townhomes are it would run down the centre of Eglinton taking up no more room than an in-median setup. There are townhomes right on Overlea, I don't believe the gov't is planning on expropriating all of those too for any OL.

I still don't understand why they want this entire stretch tunneled. Doesn't add up.

It does add up. When the next government swoops in and cancels the line in a few years, the PCs get to yell about how the Liberals want to take your subways.

I imagine Ford is not smart enough to realize what is happening, and the civil servants view this as a blank check since the gov't is motivated to build something.
Different generation - but the Highway 11 twinning to North Bay was the same. They came up with their own standards, well above the normal MTO practice, because they realized the project would go ahead regardless of cost. And why not build a bigger empire for yourself.

There is a pipeline underground under Eglinton Avenue West in Etobicoke. They have to take into consideration if they have to avoid the pipeline or move it.
I suspect there are pipelines under just about every road. It this a real concern or just an excuse.
I wouldn't be surprised if it costs $1M/km to relocate - and to avoid this they will choose construction methods that are $100M/km more expensive.

It's a major trunk line. I presume there has to be x feet of vertical separation between the tunnel and the gas line - just in case. Relocation won't fix that because the gas line crosses the route.

Wait. Does it run along Eglinton West? Does it cross Eglinton at 1 of the Arterial crossings? Does it cross Eglinton at all Arterial crossings?

I would suspect crossing perpendicular is much easier to handle as they can most likely locally protect the pipe.
If it runs parallel, then that's a pretty wide corridor. If this pipeline is under the centre of the road, then just shift the transit line within the ROW, and then onl ya few minor pedestrian crossings are required.

^See http://www.eglintonwestlrt.ca/wp-content/uploads/2017/10/Stage-One-Report.pdf

The gas main runs along the south side of Eglinton, but it potentially crosses the plane of the tunnel west of Martin Grove Rd.

The map calls it a ‘vital’ line which I take to mean they can’t just valve it off somewhere and splice in a relocated segment. From where it is above ground out that way, it’s a pretty big pipe.

I’m speculating that the issue is not so much supporting it during construction, but rather not having any underground voids (such as a transit station or tunnel) in proximity where gas might collect should the pipe break or leak. Hence the need for a tunnel to be a fair ways underground to ensure a barrier. Gas is heavier than air, after all.

Thanks,

There was some traffic study to improve this area. Essentially, the joining Eglinton happened too close to Martin Grove, resulting in Eglinton cars shooting across to the left to make the turn onto Martin Grove, while the 401 cars where coming right to continue on Eglinton. I recall that a good solution here was to move this intersection to the West side of Mimico Creek, and then there is space to elevate over Mimico Creek and never really cross the gas line. A quick read, I think the east-west gas line in 900mm diameter, and north-south ones 200mm (Royal York) to 300mm (Martin Grove) - I assume these smaller one can be relocated vertically if required.

So it seems it should be (note that the link still had the mid-block stops, so the results were skewed to have the line under the centre of the road, and also done in such a way that the mid-block stops are at-grade);
Jane - Elevated, north side.
Scarlet - Elevated, north side.
Royal York - buried, north side.
Islington - buried, north side.
Kipling - buried, north side (if you're worried about a 1 ha. parcel of woods, you may as well give up building the city).
Martin Grove - buried, north side
Line goes to the south west of Martin Grove and elevates just before Mimico Creek (EDIT: I show it going under the 427 bridges, but I could imagine a scenario where it flies over them all).
North side means tracks just to the north of Eglinton, but station excavation and EB platform under north lanes of Eglinton. Buried means all track underground, with station and track between built with cut-and-cover (and precast concrete box segments to speed construction).

If the high pressure natural gas pipeline is close to the underground LRT station at Kipling & Eglinton, that's okay. Doug Ford lives close to that intersection. So if an "incident" happens from the gas pipeline, Doug's home would be in the way. Unfortunately, his neighbours would also be in trouble.

Maybe Doug will pay for the extra precautions needed for an underground LRT next to his home.

Not gonna lie, if this thing gets built I would visit Square One more frequently. 68 minutes one-way from Yonge&Eglinton to Square One according to the Business Case using the preferred Option 4.

Regional connectivity sorta wins with this overpriced transit expansion.
The reverse is also true. I predict that the shopping/dining options along Eglinton east of Keele, that will open up for people in Etobicoke and Mississauga, will be significant. The thought of Eglinton/Bathurst bagels in my commuting reach........

While it's not on anyone's priority list, extending the St Clair streetcar to Six Points would have a similar benefit. Maybe some day.
