I'd support this. Split the entire length into a mix of developed sections (covered by buildings) and park sections (covered and then landscaped). To pay for it I would require developers that are building above the LRT line to pay into a fund to cover the park sections. High-rises immediately adjacent or on top of transit stations should be very desirable, and they would have great views as well.

You want to protect the riders view of the trench? I ride it every day and I would rather ride a train on covered tracks and read my magazine than look at rock and concrete from the bus.

It's about space. We can put all the roadways underground. Maybe if all cars are fully electric we'll be able to do that, but not now. But LRT is already fully electric so we can easily put it underground through dense areas. And in the case of the Scott Street trench we could put land back into use that was previously devoted to fossil-fuel burning vehicles.

Right. Because putting a transit corridor through unpopulated woods and along a limited-access highway is always such a recipe for transit success.

Why does it have to be a linear park?

Why not a linear unpark?

Or both?

What is this town's fetish with taking perfectly good strips of transportation corridor or land suitable for other purposes, and turning them into linear parks?

Enough with the damn linear parks.

My reason for arguing for a linear park is that there isn't enough space for development over much of the trench, especially since the demand in Ottawa for units that do not provide parking sadly is limited. Also, I feel a dedicated proper bicycle pathway is important in this area, something that could accompany the conversion.

That said, where development over the transitway is possible (for example, pretty much for the length of Tunney's), I would definitely favour it. But where it is not available, a park would be an improvement over the status quo (two high chain-link fences bordered by brush with limited cut-throughs), and by creating connections between communities, and making those north of Scott street more visibly accessible, would encourage intensification generally.

There is plenty of space for development... even if there is not much space for the kind of sad, boring, formulaic type of architecture that generally passes for development in Ottawa.

Anecdotally, when I'm on Slater and Albert for the morning and evening commutes I don't see car congestion. Lights are green for longer than they need to be to clear both the cars and the buses that wanted to pass through eastbound or westbound.
When LRT start service I would like to see the bus lanes disappear and be reclaimed as extended sidewalks. Allow sidewalk vendors and patios and such.
Doesn't this say something? Our congestion problem is caused by a reluctance to turn over more road space to transit. This all goes back to the Albert/Slater Coalition who want to eliminate surface transit as much as possible and we all know the enormous price tag that we are going to have to pay for this.

As far as your comment about sidewalk vendors and patios, we already have extended sidewalks on Sparks Street, a traditional retail street, and have not succeeded there. Why would we succeed with this on Albert and Slater, without a retail tradition and with the dominance of large office blocks shadowing the street and that don't encourage street level sidewalk facing retail and restaurants?

Our transit problem and greater urban issue stems from a reluctance to turn over more road space for sidewalks. While Sparks Street Mall is dedicated to pedestrians, it is virtually an island surrounded by a pedestrian-secondary environment filled with barriers to comfortable walking. We cannot expect to increase transit use without looking at the pedestrian situation first because transit users are simply pedestrians in between their destinations.

Surface rapid transit is not entirely compatible with the pedestrian environment. The European examples quoted are often local trams and not rapid transit. I have yet to see an example of a surface urban transit mall that claims to be a pedestrian success. In Calgary and Portland, the streets that the trains run on are not the most desired locations relative to the adjacent streets.

With proper incentives, it won't be hard to turn Albert and Slater streets into shopping streets after the DOTT is built and freed road space is given over to wider sidewalks and bike lanes. Property/business tax rates could be geared to favour open street retail over closed office space, and offer preferential rates to restaurant patios. Maybe property owners could be given a couple of years or so tax exemption for ground floor space converted from office to retail.

It should be important to note that Sparks is a failure because it does not function outside of business hours for the most part as a retail commercial destination. In Calgary after 6 pm the pedestrian mall Stephen's Avenue opens up one lane of one way traffic with limited angled and parallel parking. While it isn't nearly enough parking to fill up nearby restaurants, it is surely enough to function as teaser parking, tricking people into believing there is parking near the restaurants that now play a dominant role on the strip. This is combined with a program which encourages structured parking to allow off peak parking on evenings and weekends at especially low rates ($2 for all day on weekends, a little more on weeknights) that brings in people from all over the city to eat in nice expensive restaurants.

Granted, the shift from a situation basically similar to what Sparks is now in retail activity after business hours did take 10 or 15 years to take hold, but all it takes is a few pioneers and some good policy. Fortunately the Calgary Downtown Association got behind the initiative and ran with the ball, pushing streetscape improvements, practically forcing businesses to take patio space, and other such things. Also, Calgary's experiment has the benefit of being adjacent to the equivalent of the Rideau Centre, acting as an anchor to the pedestrian mall (Calgary just had to get people to wander down to Stephen's Ave at some point during their shopping, Ottawa is a little further than that).

I would try fixing Sparks before moving policies to other streets since critical mass is very important in the development of spaces like this.

We also have extended sidewalks and patios in the Market that work quite well. I suspect the details are probably important.

Though there are tons of neighborhoods under development along that corridor. First, between Eardley and Wilfrid-Lavigne on the north side there are hundreds of new homes and it is a short walk from several other existing neighborhoods such as Lakeview and Eardley as well as the Lavigne Gardens (near the area that got devastated by the tornado in 1994). Plus the two ends of Le Plateau will be connected in a few years and there are some less densily populated areas on the south side. The only section that might not get filled would be the north side between Vanier Road and Samuel Eddy because they are planning to preserve a significant wooded area.

The other corridor will also see significant development including the site of the former Rivermead horse race track. East of Rivermead, there are also development planned in the form of condo towers. Though less newer homes possible along that stretch then the northern area.

Pink Road is also a corridor that will see major development because of le Plateau although, the gap between the western end and Vanier Road (or moreso Kilroy Crescent) is almost filled along Pink Road, closer to the Allumettieres the gap is much larger to complete.

The big drawback on the southern corridor will be the potential elimination of lots of wooded areas and then there is the segment east of the Champlain Bridge whether it will be on Tache or further south. What might happen is that it might join Tache at St-Dominique because I doubt the Val-Tetrault residents and the Moussette Park users would like to see a BRT line cutting through. Sure for the STO the ideal would be to connect with the section under construction right beside the UQO.

The main drawback on the northern segment would be east of St-Raymond. There is no space on des Allumettieres for segregated line without 1) cutting more trees at the Gatineau Park or 2) expropriating homes along Laramee Street or 3) tunneling some sections. The most likely scenario would be that the segragated lane would eventually merge with mixed traffic at or near St-Raymond and then connects with the segment under construction at A-50. Or buses might continue on des Allumettieres until Maisonneuve or use the roundabouts and run along Montcalm which is expected to have bus lanes once they will re-built the road sometime next year barring some major changes. This drawback also concerns the Pink Road corridor

I say (as an Aylmerian) put a more tram-like system on Principal and Chemin d'Aylmer: It is the commercial and cultural centre of the city as well as the densest part. It would also pass by Rivermead Parc-O-Bus, an extremely popular park and ride where all of Aylmer's buses end up. It could be ROW in the median or on the sides of Chemin d'Aylmer up until the older parts of the city where it could mix with traffic, but at that point, car traffic isn't an issue. Trams would pass without any waiting.
Near the end of Principal, it could turn either onto the old rail trail or onto Front Street (shared traffic) and continue up to Des Allumetières where it could join up with buses from the new neighbourhoods. Aylmer, as you must understand, is a town before a suburb. We want to get people to the centre of Aylmer before we ship people off to Ottawa.

Trains along Lucèrne (Lower Aylmer Road) would be quick and cheap, since the rail bed is still left over from the original track (removed in 1991), but the catchment would be mostly in water.
Des Allumetières would be inefficient since the development around it is just sprawl. The effort would be wasted.

It's too late to protect the views of transit riders between Dominion and Bayview. If we had built a surface LRT line on the former CPR corridor as some had suggested back in the 1970s, we would today have a far different environment along that corridor. That's a "should have been", but it's not too late to at least protect their access to daylight. I too would prefer to read - using daylight if at all possible. Right now cell phone coverage is largely unaffected by the trench (though the racket of the buses makes it hard to carry on a coverage, but I'm thinking more of other smartphone uses than
just speaking), but if you cover it then every provider has to have repeater stations built into the tunnel and that requires painful negotiations with the City of Ottawa, and so on.

I would also point out that when you cover a rail line, you make it a lot noisier for those onboard because the sound waves bounce back and amplify each other. You can hear this with the O-Train going through the Dow's tunnel compared to the trench sections immediately north of it. For people not in the train, there's only a little extra noise with an open trench - in those same sections of open trench north of the tunnel, if you're standing on the Prince of Wales Drive bridge over the line an O-Train passing beneath is an unremarkable event as far as noise is concerned - unlike buses in the Transitway trench.

Basically, I think much of the desire to cover the trench is based on people's experience with the noise of the buses and wanting to rid themselves of it.

The land is a 100' RoW, which is a standard lot depth. The corridor might look wider, but that's probably due to the 66' Scott Street RoW that abuts it, so the unused portions of both RoWs meld together to make it look wider than it is. Much of this combined corridor also has enormous trunk water and sewer services running along it. So for most of the corridor, from a development perspective, given the lack of opportunity for subsurface parking and the fact that the property is only 100' deep, you're basically limited to ground-oriented units fronting Scott with some kind of surface parking, probably accessed from the north side streets/lanes and probably having generous real and apparent setbacks from Scott to accommodate the water infrastructure that lies between the trench and Scott. Given all that we'd be talking about 3-4 storey townhouses for the most part, with them maybe being live-work units (with the parking and work unit level providing a "buffer" to the tunnel below from the residential units above); only at locations like Westboro Station or around Tunney's Pasture where other adjacent redevelopable properties exist could one realistically expect anything more. I'm not sure that one could really justify covering over the trench just to build a line of townhouses from Carruthers to Roosevelt, and even less so yet another linear park.

CTV is reporting new fault-line and rock issues:

Downtown fault line may cause glitch for light rail project

Updated: Tue Dec. 21 2010 11:39:08 AM

ctvottawa.ca

A fault line in downtown Ottawa may cause difficulties for the city's new $2.1 billion tunnel and light rail project.

Crews discovered the fault line after drilling about 200 boreholes to test the quality of the rock along the tunnel route. The fault line runs along O'Connor Street. There are also issues with rock close to the University of Ottawa.

Tests found that the quality of the rock in other areas is good to excellent.

The fault line report may force the tweaking of the rail line route.

Ottawa was rocked by a 5.0 magnitude earthquake in June.

City considers shortening tunnel to keep rail plan on budget


By Neco Cockburn, Ottawa Citizen December 21, 2010 11:52 AM

OTTAWA - City of Ottawa staff are exploring the possibility of shortening the length of the planned downtown light-rail tunnel by up to almost one-third as a way to make sure the price of the project stays in line with the estimated $2.1-billion cost.

Staff said during a councillors' briefing that shortening the planned 3.2-kilometre tunnel by 600 to 900 metres is an option being considered, although more work is needed.

The current plan is for the tunnel to contain four underground stations, but a potential modification would see the Campus station at the University of Ottawa placed on the surface rather in the tunnel, and the tunnel's east entrance would be located on the existing Transitway, south of Laurier Avenue.

(Current plans would see the entrance located just south of the Campus station, near Mann Avenue).

One of the reasons that shortening the tunnel is being considered is that first phase of geotechnical work found bedrock south of Laurier near the Campus station that is two to 10 metres deeper than had been anticipated, according to staff.

A preliminary design team has suggested staff look seriously at moving the station to the surface, staff said. That would save money on possible groundwork that could be needed to shore up the softer material that a tunnel-boring machine would have to cut through closer to the surface.

A shorter tunnel would cost less, but it's too early to say how much would be saved, staff said, adding that more work is needed before potential plans could be firmed up.

City ponders shorter downtown LRT tunnel


Engineers present first report; some changes could be on the way


By JON WILLING, City Hall Bureau

The city is toying with the idea of shortening the planned downtown LRT tunnel after reviewing the first preliminary engineering results.

Staff tasked with implementing the light-rail plan said Tuesday the bedrock is deeper than expected near the proposed Campus Station at the University of Ottawa.

That might convince planners to shorten the tunnel up to 900 m and build the Campus station on the surface instead of underground.

As a result, the cost of the $735-million tunnel could decrease if it's shorter and there's one fewer underground station.

The total estimated cost of the LRT project is $2.1 billion. The 12.5-km. electric rail line would run between Tunney's Pasture and Blair station, via the downtown tunnel.

The tunnel has been planned to stretch 3.2 km between Bronson Ave. and the U of O.

Staff said the engineering so far has indicated the project will be within budget.

Another challenge emerging is shortening the project timelines.

Kanata North Coun. Marianne Wilkinson wonders if the project could be done faster than the 2019 opening date. She said it would be a "nice gesture" if Ottawa had LRT in time for Canada's 150th anniversary in 2017.

John Jensen, the city's rail implementation director, said bidders will be challenged to advance the timeline.

Other changes being considered by staff include shifting the alignment at the VIA rail station slightly north to accommodate development in the area and the pedestrian bridge which will span Hwy. 417. Staff are also looking at "simplifying" the plans for Bayview station and phasing in the construction.

This is probably WAY too late for such a criticism, but why can't we have the LRT surface just after going under the canal and have it follow the same path as Mackenzie King currently? We can still have connections to Convention Centre, Westin, Rideau Centre, DND. People don't seem to mind walking through Rideau to get from the bridge to Rideau Street and the Market currently so why does it have to change? The only other change would be that Nicolas would have to be cut-and-covered under the LRT ROW which would actually be great for pedestrians going between the U of O and Rideau (there are tons of them) as they won't have to stop for the ridiculous amounts of truck and car traffic heading to and from Quebec. Just a thought....

That was in fact the option originally considered, but the turn from the bridge to waller has a radius way below spec (it's practically a right angle): the train would have to slow down considerably in between two stations and that would increase travel times unacceptably for the whole system in such a central point.

That is my new recommendation as well. Tunnel under Albert and Slater, surface over Mackenzie King, elevated over Nicholas and Laurier then back to surface (or return to tunnel?) to Lees.

Nice try... but they are putting in turns that are just as sharp (100 m radius) between Hurdman and Train (the current alignment between those two stations is only going to be partially reused - mainly the bridge over Alta Vista and its immediate approaches) - and that's two curves in short succession, not one. "Slowing down" is also a non-issue at that location since the train would have to be going fairly slow anyway due to the nearby Rideau Station. That's in marked contrast to the curve immediately west of Alta Vista between Hurdman and Train which is going to keep vehicle speeds down for the entire trip between those two stations.

The reason I recall was that the weight of the bridge embankment/support along with the soil types it is sitting on would make station construction at that location particularly difficult. They could however put it under Daly since there is nothing below Daly itself.

How much money would be saved if my idea was done (tunnel under Albert/Slater, re-use existing Mackenzie King Bridge, elevated over Nicholas and Laurier)?
