Hope Springs Eternal for Light Rail City

LRT tightIn answering questions from Councillors during last week’s LRT routing debate, Transportation Department officials showed us a conceptual map of the full potential build out of our region’s LRT network to illustrate some points about connectivity.

It caught all of us by surprise — pleasantly so. I called it the ‘Hope Springs Eternal’ map. I also asked for a copy to share as it’s now in the public realm. Enjoy.

A couple of important qualifiers: this was for modeling purposes only, and does not presuppose Council’s ultimate decisions about alignments currently under debate (SE and W) or future projects (NW and E).

This map (prepared by our consultants Steer Davies Gleave) has roots in earlier decisions Council gave with respect to the overall LRT Network Plan as well as the ‘Urban Style’ system commitment of more frequent stops and low-floor technology. I wrote about these decisions previously here.

The issue at this level is not whether a given line or station go here or there, but how eager are we to bring a vision of this ambition to life? It’s certainly not up to the city alone — projects like this require the alignment of at least two and, properly, three orders of government. It will require the relentless pressure of citizens on Councillors, but more particularly on MLAs and MPs.

I’m game.

The Way we Grow/Sprawl

Good urban form, by way of example.

I caused a bit of a stir on Thursday at Council by raising some concerns about the city’s proposed development plan ‘The Way we Grow’. I rather flippantly suggested we could call it ‘The Way we Sprawl.’

Scott McKeen wrote about the plan in Friday’s Journal and his critique is similar to mine. In spite of what he said, there are some very positive things in this plan, so I don’t want to write it off completely. I’ll come back to that.

First, though, the part of the plan I spoke against and voted against yesterday is the part where our expectations for relative share of growth are set out, which is section 2.1.1.2, on page 13, which reads:

Encourage a greater percentage 25% of city-wide housing unit growth to locate in the Downtown and mature neighbourhoods (see Map 3: Mature Neighbourhood Overlay) and around premium transit locations where infrastructure capacity supports redevelopment.

The underlying assumption of the plan is that the city will grow by 400,000 people in the next 30 years. This means 75% of the units will be outside of the core and away from ‘premium transit’ (i.e. LRT or the very best bus service). Furthermore, since we’re assuming that households occupying infill and intensification units have fewer members, 25% of units in the core only comes to 20% of the people (which has been our experience, since families with children still largely flock to the suburbs, vs. the singles and empty nesters who may pick smaller units with better locations). On other words, our plan presumes that 320,000 people will locate on the periphery, near or beyond Anthony Henday Drive.

I find this tough to swallow.

But here’s the plan’s qualifying statement in the plan about how fast we can ‘turn the ship’ from our suburban character to urban, from page 12:

Changing our current growth pattern will take time.  Edmonton’s mature neighbourhoods received 18% of the city’s growth in housing units in 2007; despite this unit growth, the population in these mature areas has declined in recent years.  Between 2005 and 2008, mature neighbourhoods declined in population by 1%.  All new population growth during this time occurred in other areas of the city, primarily in our developing communities.  The MDP proposes a new direction for growth and it will take time to effect change.  The Plan is a long term strategy and will require incremental decisions that support our commitment to saying “yes” to the things we want and need and “no” to the things that do not advance our City Vision and goals.

I think we need to ‘turn the ship’ faster and push for a bigger share of growth to be urban, rather than suburban, over the 30 years of the plan. Easier said then done, yes, but let’s ask why would it be desirable to urbanize at least as much as we suburbanize?

  • A less efficient city will cost more to serve well, or will end up with declining services. We know these peripheral neighbourhoods will be very expensive to deliver services to and maintain infrastructure for; things like fire protection, waste collection, and transit will be more costly to deliver to further suburbia than if we densify the exiting footprint properly. This is intuitive, but the city is also studying this. Wish we had the results.
  • Peripheral neighbourhoods, no matter how walkable or attractive, will lock in automobile dependancy for the vast majority of their residents. There is well-documented public health evidence that automobile dependance leads to higher rates of obesity as well as impacts to emotional well-being. Our council-stated goal to see a shift from car use to other modes of transportation (principally transit, walking and cycling) stands in jeopardy. This means more traffic, more delay, more private and public expense on cars and infrastructure.
  • Plus there’s no way we achieve community-wide reductions in greenhouse gasses with rising distances travelled by car and worsening downstream gridlock.

In other words, for fiscal, social and environmental reasons, there is a strong case against conceding to so much peripheral development. Again, I’m not calling for a halt to it, since I don’t see how we could accomplish that under current legislation. I’m calling for greater urbanization within today’s footprint. We’re told that market demand’s not there, that demand is for the suburbs, and that we can’t fight that. But I think we have to work to make urban living more family-friendly – which we’re beginning to do – and we need to make it competitive in terms of affordability. This is work worth doing, even if it’s hard. It doesn’t mean cramming families into highrises, it means more duplexes where there are bungalows, nice townhomes where there are underused lands, and family-oriented units on the ground floor of some taller buildings. That, by the way, is city building.

I should note that there is much to like in the plan: the parts that deal with integrating transit and land planning in established areas are positive (section 2.3); the new provisions in chapter 9 about Urban Agriculture and Food are very encouraging; and the design principles for planning in established and new areas are sound in my view (e.g. chapter 3).

The one outstanding issue we’ll grapple with next time Council deals with the plan in February is density targets for new development. These are mandated under the Capital Region Land Use Plan, but these were not going to be discussed in our MDP. At my urging, they will be. Targets were a source of significant debate in Calgary’s recent plan, and were watered down before final passage. If we can achieve sufficient thresholds of density in the new areas then some of the inefficiencies and negative impacts of this growth can be reduced.

A Lego Urban Design Primer

Sarah and I were at the store picking up some things for the newborn, and I wandered over to the Lego section to see what the latest ridiculous theme lines were (something went wrong between Castle Lego and Star Wars Lego, in my view). It just so happens that they have released a line that feels like what I grew up with in the ’80s: the City series.

lego boxAlthough he won’t be old enough to play with it for a few years (he’s two weeks old today) I bought Dexter the ‘City Corner’ set, which just so happens to be a superb example of sound urban design.

Notice first the mixed use development, where people can live and work in the same spot, in this case there is residential use above the pizzeria. Almost every truly vibrant place has a mix of land uses, as opposed to segregated uses where people live in one district, work in another, and shop in yet another, etc.

Second, it’s an active street, featuring the following:

  • Sidewalks: you would think these go without saying, but think of the streets you know without sidewalks, and I guarantee you’re thinking of a place you wouldn’t want to walk. Notice that it’s cycle friendly as well.transit
  • Effective transit: I’m assuming because Lego is European that the transit is frequent and reliable, which makes this spot an appealing point of origin for people who live here, and an easy-to-access destination for visitors.  (I added the pantograph to the bus, figuring that if it’s European it also ought to be electric.)
  • Defined edge: a line of buildings built to the sidewalk, which join to form a street wall which defines the space. (I’ll need to dig out some of my classic Lego to add some more buildings to really bear this out, which I probably won’t have time to do until Dexter is talking.)active31
  • Active building frontages: the businesses themselves contributes to a positive pedestrian environment; however, the presence of commercial activity is not sufficient in and of itself. To make it work, the frontage must be permeable (the businesses are inviting and accessible from the street) and fine-grained (in that the individual business frontages are not too wide, therefore offering many options to strollers and contributing a sense of rhythm to the street).
  • Crime Prevention Through Environmental Design (CPTED, or ’sep-ted’ as we say): part of the benefit of having activity at all hours, which comes more easily with mixed use, is having ‘eyes on the street‘ which helps deter crime. Notice also the lighting on the buildings, which eliminates dark corners. For bonus points, the lighting is all downward casting, which reduces light pollution (which is light waste when you think about it) and is generally more energy efficient.

The only missing things I can think of are: secure bike parking, renewable micro power generation, public art, and a bit of green space. All in all, still a surprising example of a “place worth caring about” in the words of urbanist James Howard Kunstler.

An Urban Vision for LRT

The city just unveiled a consultant’s report with a high-level vision for the long-term LRT network, which aims to take rapid transit to all corners of the city, though with a different flavour than we’ve known until now. Council will hear from the public and debate these recommendations at the Transportation and Public Works Committee on June 2.

I took this picture of the sleek and popular LUAS on vacation in Dublin in 2008.

With a general consensus that our city needs to ‘grow up’ instead of ‘grow out’ (or at least achieve a better balance of infill redevelopement and intensification versus so-called ‘greenfield’ development) the consultants have recommended that Edmonton develop an LRT with an ‘urban’ feel, instead of the more ‘suburban’ system we’ve been developing.

The key differences between an urban and suburban system is the separation between stations: suburban system stops are up to 2.5km apart, whereas urban system stations are 400-800m apart. The advantage of the urban style is that you begin to develop corridors of density, where the density is spread more evenly along the LRT, rather than in isolated nodes. The tradeoff is that travel long distances on the LRT takes a bit longer, but if our end goal is to build the core, not encourage more suburbs, then urban style is the way to go.

This does mean LRT out to the International Airport and for example, Spruce Grove is less likely, but LRT technology was never well suited to that since it’s top speed is 80km/h and since electrification is most efficient with frequent stopping and starting, not long runs. A fast rail or bus link to our urban LRT system is more appropriate for getting out to the region. Where we’re contiguous, as with St. Albert, an argument can still me made to connect with LRT; Sherwood Park as well, in time.

I am hopeful that if these recommendations are approved by Council that the argument for a station near Harry Ainlay at 40 Ave on 111 St will gain traction, understanding however that it would come with some redevelopment as well.

The other key recommendation is to look at a ‘low-floor’ style of system for the West, East and and Southeast lines. These board from the curb and are much less infrastructure-heavy. Low-floor LRTs are not streetcars because they still run in their own right of ways, but those right of ways are cobbled or sometimes even vegetated, as opposed to the great grey swaths that we’re used to.

Having ridden the Dublin low-floor system last year I can attest to the lovely sense of appropriate scale as it worms its way through the city, stopping frequently enough to have an impact but without disrupting the underlying feel of the city.

central-circulationThe recommendations call for a shift in the bus service to feed the LRT and connect the ’spokes’ with better crosstown service.

They also call for looking at building a ‘central area circulation’ by connecting the University Area on the South LRT with Bonnie Doon on the SouthEast LRT via Whyte, which is very exciting in my mind — finally recognition that the core of the city spans the river and includes both Downtown and University/Strathcona.

What do you all think of it?
