Even if you’ve been doing nothing but glimpse at the headlines of Ottawa’s major dailies, you doubtless know about the “rising” costs of the City’s light rail plans. With the first phase projected to top $2 billion, the province is starting to get cold feet over helping to fund the project, and it seems like many people are getting antsy over exactly how much the City will have to shell out to get things done.
Others have already done an excellent job of deconstructing the numbers that are floating around, showing that things may not be as bad as they seem, but the fact remains: the plan is now percieved as being too expensive. Regardless of the plan’s actual value and cost-effectiveness, it’s possible that it will need to be scaled down in order to secure funding from higher levels of government. So my thought is, why not a combined surface and underground system in the downtown core? Here’s a map I threw together:

Blue is surface rail, red is tunneled. Train symbols represent potential stations. Map created using Google Maps.
In this proposal, rail would follow the Transitway to Lebreton, where it would divert north along the current alignment of Wellington Street—currently used for tour bus parking, I believe—before diving underground for a short tunneled section at Commissioner Street. A slight curve under Bronson Park would line the rail up with Sparks Street, where it would come aboveground just after Bay. From there, it would run along Sparks with stops at Lyon, Bank, and Metcalfe, before diving back underground to curve around to Mackenzie King and Campus stations.
Before I go on, I should say that this is entirely conjecture. I’m not certain if any of these curves or climbs would actually work for LRT vehicles, it just seemed like the most logical way to do things at the time.
I think there would be a number of advantages to this idea. Most notably, it would remove nearly a kilometre of tunnel, which, at a guess, would probably shave $60–70 million off the bill, along with allowing for surface stations instead of underground stops, also representing a significant savings. Furthermore, I chose Sparks Street for the surface section for a reason: having trains running along that corridor would do a lot to improve the liveliness of that half-abandoned pedestrian mall, giving people a reason to be there outside of office workers on their lunch breaks.
Of course, there would be obstacles. The National Capital Commission would of course be reluctant to allow trains on Sparks, something that would need to be heavily negotiated. And it still wouldn’t be cheap, just somewhat less-expensive, so it would hopefully be more palatable to the McGuinty government.
Sparks is not the only option for surface rail, either. Albert and Slater could theoretically be used, as they are now, however I think it would be difficult to remove the need for tunneled sections entirely. If the current Transitway lanes were used, leading to the Mackenzie King Bridge, then an extremely tight turn would be required to align trains up for the run to Campus station. Either a tunnel would be needed to make a more gradual turn, or a serious reconstruction of the area around the east end of the bridge would be necessary.
In all, while it would require a lot of work and a lot of inter-agency co-operation, I think Sparks Street is the most logical place to build a section of surface rail, if we decide it’s neccessary to reduce the plans cost. At this point, I think it would be premature to scrap the current tunnel plan entirely, but it is at least worth considering our alternatives.




Urban Barrhaven?
Tags: barrhaven, development, mississauga
When Ottawans think of dense, urban neighborhoods, chances are good that Barrhaven is not high up on the list. In fact, most of us probably wouldn’t even put it on the list in the first place. However, it seems that Minto is trying to change things with a proposed new town “centre” for Barrhaven. I’m chosing to put centre in quotation marks simply because this development is not so much central as it is stuck on the southern end of the suburb, but it is an intriguing proposal nevertheless.
First, let’s take a look at the proposed location.

Located south of Strandherd and west of Greenbank\Jockvale, this is very plainly a new development. There’s no real urban fabric on the site right now, as it’s merely a collection of fields south of a big box\power centre development. Unfortunately, this means that it is a greenfields development, and one that pushes the boundary of Barrhaven further south and west, which is the proposal’s most negative aspect. However, this is balanced by the nature of the proposal.
As described in the article linked, the development will be reasonably dense and mixed use, with 1,200 residential units. Even taking the most conservative population numbers (assuming one resident per unit) that represents a population density of about 95 people per hectare, putting it right up with many of Ottawa’s dense neighborhoods in the core. The addition of office and retail space, as well as nearby transit infrastructure with the southwest Transitway extension definitely makes this a very progressive proposal for an area like Barrhaven. And provided it complies with the City’s urban design guidelines, it could become a genuinely urban space.
I’m not without my reservations, however. It’s becoming more and more common for developers to claim they are building a “new downtown” somewhere—it’s currently happening all over the Greater Toronto Area in reaction to Ontario’s Places to Grow initiative—but it remains to be seen if any of them achieve a true urban experience. Perhaps the best case study we have for this kind of suburban downtown is Mississauga, which is quite dense and actually has one of Canada’s most significant concentrations of high-rise development, but is a long way from vibrant.

While dense, Mississauga is still fundamentally suburban in character. Roads are wide, and cars are still the prefered transportation mode, while buildings ignore the street. It’s a common shortfall of these kinds of developments, and one which the Minto development should strive to avoid. Mississauga is not a perfect analogue, of course, as there is no mall anchoring this development, and the overall height is lower, however there are lessons to be learned. Keep roadways narrow and stops for cars frequent, so that pedestrians have priority over traffic. Don’t forget the sidewalk, and have plenty of shops and buildings fronting directly upon it, while removing parking lots that face right onto the street.
Creating a downtown instead of having one growing organically is always a challenge. I think it can be done, given good design and by paying attention to the mistakes of the past. This is a potentially important development for Ottawa, and hopefully Minto can come up with something interesting and urban.
